The Eckart HSE4 rotary-linear actuator is a combination of a rotary actuator and a dual-action linear cylinder, allowing for full flexibility in a minimal amount of space. Consequently, both a rotary movement and a linear movement can be executed even when operated in an extremely small area. Additionally, since the rotary actuator and the linear cylinder are hydraulically-driven separately, any movement sequences can be selected: for example, rotating to the left and right, extending linearly, and retracting.
Furthermore, if both components are driven evenly, then both types of movement will be executed synchronously. The directional valve controls the movement of rod rotation and linear stroking. Because of its torque, angle of rotation, pressure range, positioning accuracy, stability of position, type of attachment, and its dimensions, the Eckart HSE4 rotary actuator can be used in a wide range of applications.
Common applications for the HSE4 include lifting and turning. Not only is the HSE4 a compact and robust unit, but it is also wear-resistant, efficient, and cushioning. Additionally, the HSE4 unit can be driven via “black and white” or with proportional, control, and servo valves. For the purpose of subsequent driving, the piston end-positions at the linear cylinder and at the rotary actuator can be scanned via electronic end-position acknowledgement mechanisms. Ultimately, with the HSE4, you have a high-performing product that is both robust and compact, allowing for optimal adaptation depending on your specific requirements.

Helical Spline Hydraulic Rotary Actuators:
Our rotary actuators are the helical spline design. This means, a piston and a helix, or sliding spline, work together to convert the linear motion of the piston into rotational motion. Composed of two moving parts and some form of housing, the sliding helical splined gear concept within the actuator is used in many applications where a rotary movement is required. Helical Spline Actuators function when the piston is axially displaced using hydraulic pressure causing simultaneous rotation of the piston. Standard amounts of rotation are 90°, 180°, and 360°; but are available generally up to 720° or more. Additional rotation is created by making the spline gears longer while maintaining the same diameter. The primary benefit to this type of product compared to alternative designs such as linkages using hydraulic cylinders (linear actuators) is its compact design.

Hydraulic Press Products — Parallelism Control System
The Hylatechnik parallel leveling device preserves the life of presses and machine tools, increasing the economic return on your equipment and the quality of the work piece.
Often press manufacturers and tool makers are asked to design a press or die with severe off-center loads. The off-center load forces the slide to tilt placing high side thrust loads on the slide, gibs and frame. The result is abnormal wear of gib and slide liners, improper die alignment, reduced die life and lower part quality.
The Hylatechnik Parallelism Equalizer consists of four cylinders set beneath the ram and connected to a specially designed metering system. The instant the cylinders come in contact with the ram, oil in the cylinder flows to the metering system. The metering system prevents any of the cylinders from moving ahead of the rest, assuring parallelism.
The Hylatechnik Parallelism Equalizer permits the placement of tools with off-center load conditions without twisting the ram to non-acceptable conditions. Press and tool life is increased and common use of cutting, drawing, trimming and contouring tools become possible.
Purpose:
Corrects off-center loads in hydraulic presses
To prevent press ram from taking out of parallel positions, even with severe off-center loads
To permit the simultaneous use of several dies on the press for better machine utilization
Particularly suitable for use with progressive tooling
Results:
Parallelism of ram is accurately maintained, even with severe off-center loads
Press and tooling is protected
Economic utilization of machine is increased
Quality of work piece is increased

Have you ever been in a metal stamping facility and heard something that sounds like a train running into the building every time the press cycled? If you have, what you are hearing is an event called reverse tonnage and it is tearing up the press. In this short explanation, we will attempt to explain Reverse Tonnage also known as Snap-Through in a metal stamping press. Reverse tonnage is the undesirable results of cutting, blanking, and perforating operations. In the stamping process, the moment the punch meets the material, the press frame begins to deflect until the press has built up enough force to exceed the shear strength of the material and the punch breaks through. When this happens the press frame will release the stored-up energy and snap back past its original position or resting position into a compression load.
The press frame and components that are designed to function in a tension load are now in a compression load condition and all of this will occur in less than 20 milliseconds. At the instant of breakthrough during blanking, the press and dies are subjected to severe stress. This compression load condition on the press frame is called reverse tonnage and it can damage your press.
The conventional industry standard is to have presses designed to accept a reverse tonnage load that does not exceed 10% of the maximum forward capacity of the press. In other words, the maximum allowable reverse load for a 600-ton press is 60 tons. So, anything over 60 tons, you risk damaging your press.
So, what happens when we have too much reverse tonnage?
Fatigue failure of press components — especially in the slide connection area, but also main frame parts. Sooner or later, this could result in damage to bearings, seals, gibwayes, etc.
Premature wear of punches and die components
Foundation issue along with a high noise level
Components like bolts, air, and hydraulic lines become loose causing unnecessary leakage
Electrical malfunctions
High snap-through affects the operator and could cause fatigue, foot, ankles, knees, hips, and even back problems
There are several ways to reduce reverse tonnage in a blanking operation:
Change raw material to a softer, thinner type if the job allows for it
Maintain punches to limit the applied tonnage or step the punches
Reducing the press speed helps, but it increases the production time
Place the tooling in higher tonnage capacity presses
Many times, these reduction methods are not practical or may only minimally reduce the reverse tonnage on these heavy-hitting jobs. However, the hydraulic Shock Damper is the solution. Hylatechnik developed the hydraulic Shock Damper over 45 years ago and stampers from around the world have been protecting their equipment by using them.
Hylatechnik Shock Dampers are designed to protect the press and tooling from snap-through loads. The Hylatechnik dampers will reduce or eliminate reverse loads, floor vibration, noise, and will increase tool life as well as forward tonnage in many applications.
Applications include hydraulic presses, mechanical presses, and press breaks. The shock dampers are not limited to the press size. They can be used on the largest of machines.
Additional benefits of the Hylatechnik Shock Damper are:
Increase press speed
Use full press capacity
Reduction in foundation vibration
Reports have shown a reduction in floor vibration of nearly 40%
Reduction in noise levels
According to AIDA Americas research, they found that the reverse load can be reduced by 83%-99% in some of their presses by using the Hylatechnik Shock Damper.

Real-Life Customer Testimonials:
Reese Products: 25% Reverse load tonnage reduced to 0.01% on a 400-ton press:
As part of the demonstration, Press Automation installed Hylatechnik Shock Dampers onto a 400-ton Niagara press. Before the Dampers were added, the press was seeing a reverse load of 100 tons or 25% tonnage, significantly exceeding the recommended 10% of the rated forward load in a reverse load situation. By placing the Hylatechnik Dampers on the press, the reverse load was reduced to 0.01% tonnage or 1.2 tons. There was also a substantial reduction in the noise around the press with the Dampers in place. FYI: 100 tons ÷ 400 ton press = 25%
Bobcat: 1700-ton press shows a drastic difference in vibration with Shock Dampers:
Shock Dampers tested on Bobcat’s 1700-ton press resulted in “a drastic difference in vibration felt and ‘crack’ heard. With the dampers, the press stroked almost as smooth as if the die was stroked empty,” Dave Owens, Manufacturing Engineer in a test report for Bobcat.
A customer contacted us for assistance in reducing floor vibration and reverse loads on their 1600-ton Version Press. The press was being used for a heavy blanking application, which caused severe floor vibration and high reverse loads. The vibration was so intense that it caused a shock that traveled to neighbors across the street, prompting them to contact local authorities and shut down the stamping facility’s production at 11:00 P.M. We were called to do a demonstration of the Hylatechnik Shock Dampers, along with an engineering firm, to document the foundation vibration caused by each press stroke. The results were remarkable and using the Hylatechnik Shock Damper System reduced the floor vibration by 40%. The Shock Dampers also reduced the reverse load within the press manufacturer’s acceptable range. In the assessment provided from HGC Engineering, Brian Howe, MEng, MBA, PEng wrote that the Shock Dampers “provided an improvement in vibration levels occurring on the press frame and transmitted to the surrounding ground.”

Hydraulic Press Products — Hyla-Lift Die Splitter Cart
Hylatechnik Hyla-Lift is a portable hydraulic die separator cart. The cart is used for die setting and die separation. Hyla-Lift replaces sledge hammer and crowbar, saves working time and protects tool guides.
The four lifting cylinders have exact parallel motion even with unequal tool loads. This allows the operator to release the tool jam and lift the upper plate level. Unequal distances between tool top and base are equalized with the adjustment screws. Longer separating strokes than the actual cylinder stroke allows are achieved by repeated lifting and supporting action. The cart is available in three different lifting capacities, 10, 30, or 40 tons.

Hydraulic Press Products — Die Splitter Turnover Device
The Universal 1972 Die Splitter/Turnover Device is the ideal equipment for testing and spotting dies. The up and down movement of the upper plate is driven through two ball bearing screws connected by two gear motors with two encoders for perfect synchronization. The upper cross member can be rotated by 180° allowing work to be preformed quickly and safely. Dies are split and turned over quickly in under 2 minutes and safely without injury to workers.
The hydraulic power unit drives the rotation of the upper cross member and provides the power for the lower plate to slide out of the machinery. The parallels with “T” slots for die clamping of upper and lower tooling can be moved in order to install dies of different dimensions. These parallels move easy on the ball bearings supports.
Designed to perform several operations without having to use other tools: – Testing the mechanical operation of a tool without having to use a costly traditional press – Changing versions on dies without having to stop the press for longer than is needed to remove the tool – Enabling just one operator to open and split the two sections of the die without having to use jacks or bridge-cranes – Quickly turning over, in total safety, the top part of the tool without exposing personnel to the risks which this operation involves
The die splitters are available in different sizes: – Entry-Level ELI15: 1,500 x 1,000mm and 1.5 ton dies – Entry-Level ELI30: 2,000 x 1,300mm and 3 ton dies – Small: 2,000 x 1,300mm and 6 ton dies – Medium: 3,600 x 1,500mm and 15 ton dies – Large: 6,000 x 2,400mm and 65 ton dies
