from Lemacher Hydraulik®
Energy efficient, precise and fast 40 to 10,000kN
The innovative products successfully developed in over 45 years are combined in our hydraulic presses. With our energy-efficient HYDROQUICK® systems and the press design developed by Lemacher Hydraulik, we create a resource-efficient solution with our experience. Our hydraulic presses are versatile and can be mounted flexibly to suit the range of applications of our customers.
With our press design we achieve a maximum of precision and stability. We clamp the press yoke and the press table between the tie bars and thus create a high degree of stiffness in the press frame. The tilting rigidity is thus further improved and the frame centres itself automatically under load. The ball rail guide optimizes the precision and increases the overall running time of the press, even without complex parallel programming. This high precision is particularly important in order to maintain exact repeat accuracy and minimize tool wear. Apart from this, no additional guides are required on the press tool.
The HYDROQUICK system was specially designed for use in fast hydraulic presses. The three-chamber principle makes it possible to freely select the rapid and power stroke paths. The area ratios in the system can thus be adapted to the requirements.
Above all, however, this system is responsible for saving energy and large oil volumes. This advantage means that the running costs of Lemacher hydraulic presses are considerably lower compared to conventional hydraulic presses. Detailed descriptions of the energy efficiency of the HYDROQUICK systems can be found here.
A further highlight is the cutting shock damping integrated in the HQE system, which can be optionally switched on in our servo hydraulic presses. Additional energy sources or additional space are not required for damping in our HQE system. Equipped with this, noise and stress for man and machine are reduced to a minimum.
The current ultimate in the field of hydraulic drives for presses ensures servo hydraulics in symbiosis with our HQE system. Our servo-valve controlled and speed-regulated drive ensures highest accuracies with simultaneous extreme energy savings. This combination results in synergies that make our hydraulic presses the most efficient and dynamic of their kind.
Example using an HT-0160 servo hydraulic press
Steel press substructure, with screwed-on press frame in rigid steel design. HYDROQUICK - rapid stroke cylinder, with slide bore or slide plate with linear guides and displacement measuring system. Fail-safe Siemens SPS control. The change-over points for rapid feed, power stroke and rapid return as well as pressure and speed are separately adjustable for set-up and automatic operation and can be stored in the PLC as required. Dynamically optimized motion sequences of the ram movements with optimal decompression are easy to adjust. The result are quiet aggregates due to the system-related small internal gear pump. The presses can be integrated into an existing workflow or supplied as a single workstation with a light curtain or with two-hand control.
Applications: Punching, punching, bending, flanging, drawing, embossing, riveting, edging, etc.
