Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic punching machines, in particular to a hydraulic punching machine with high precision. Background Art
[0002] A hydraulic punch press is a machine tool that uses a hydraulic system to drive a punch for stamping. It is usually used for punching, cutting, forming and other processing operations on metal sheets. The hydraulic punch press has the characteristics of simple structure, strong impact force and easy operation. High-precision hydraulic punch presses can achieve precise punching, cutting and forming of metal sheets to meet the processing needs of workpieces with high product precision requirements. It has a high processing speed and efficiency, and can quickly and accurately complete the processing of large quantities of workpieces, thereby improving production efficiency.
[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:
[0004] (1) Lack of material limit devices. The workpiece may shift or swing during the processing, which will lead to a decrease in processing accuracy and affect product quality. Failure to set a limit device may cause the workpiece to be unstable during processing, increasing the safety risk of operators. There are safety hazards such as loose clamping and workpiece flying out. It is easy to be affected by external factors and cause displacement or deflection. The processing error will increase, affecting the accuracy and consistency of the product.
[0005] (2) Workpieces of different shapes and sizes may require different limiting methods. If only a single limiting device is set, it may not be able to meet the diverse processing requirements, limiting the applicability of the hydraulic press. A single limiting device may not be able to meet the limiting requirements for multiple directions of the workpiece, resulting in affected processing accuracy. Especially for workpieces with complex shapes, the accuracy may not be guaranteed. A single limiting device limits the flexibility of the operator to adjust the limiting method according to actual needs, which may lead to the inability to effectively adapt to the requirements of different processing tasks.

By starting the hydraulic telescopic rod 7 to extend toward the lower end, the pressure plate 4 is driven to move toward the lower end synchronously. The moving pressure plate 4 further drives the hinged rod 2 16 to rotate with the connecting rod 3 21 as the center, thereby driving the hinged rod 1 15 and the hinged rod 2 16 to rotate with the connecting rod 2 20 as the connection, so that the hinged rod 2 16 drives the rotating baffle 19 to rotate with the connecting rod 1 18 as the center, and the rotating rotating baffle 19 pushes the clamping blocks 10 at both ends to move outward. When the rotating baffle 19 remains in a vertical state, it is affected by the elastic potential energy of the damping spring 2 14 to pull the extension rods 11 on both sides to move inward, and at the same time drives the connecting slider 13 at the lower end of the clamping block 10 to move with the guide rail 12 as the track and tighten inward, thereby automatically clamping the internal material.

When the rotating baffle 19 remains in a vertical state, it is affected by the elastic potential energy of the damping spring 2 14 and pulls the extension rods 11 on both sides inward. The part moves, and at the same time, the connecting slider 13 at the lower end of the clamping block 10 is driven to move with the guide rail 12 as the track, and tightened inwardly, so as to automatically clamp the internal material. When the hydraulic telescopic rod 7 is started to extend and retract toward the lower end, the limiting sliders 8 fixedly connected at both ends of the hydraulic telescopic rod 7 slide on the surface of the limiting rod 5, so as to limit the hydraulic telescopic rod 7 when extending and retracting downward, thereby improving the hydraulic accuracy.
