Stamping device with buffer structure

Abstract

The invention discloses a stamping device with a buffer structure. The stamping device comprises a machine tool, a supporting frame is connected to the left side of the machine tool, an electric control box is connected to the left side of the supporting frame, a fixing base is connected to the top of the right side wall of the supporting frame, an air cylinder is connected to the bottom of the fixing base, the bottom of the air cylinder is connected with an upper die base, and a pressing column is connected to the bottom of the upper die base; the top of the machine tool is connected with a workbench, the top of the workbench is connected with a lower die base, and the lower die base is located under the upper die base. The stamping device with the buffer structure is reasonable in structural design and easy to operate, a workpiece can be continuously punched, a pressing block descends along a buffering cavity to extrude buffering liquid, a concave part on an inner pipe is extruded outwards to slightly deform, meanwhile, a protruding part of a reinforcing hoop deforms due to outward abutting and pressing of the inner pipe, inward tightening force is generated, the tightening force can counteract part of liquid pressure, a good buffering effect can be achieved, damage to stamping equipment and a die is avoided, and the service life of the device can be prolonged.

Description

technical field [0001] The invention relates to the technical field of punching devices, in particular to a punching device with a buffer structure. Background technique [0002] Stamping die is a special process equipment for processing materials into parts in cold stamping processing, called cold stamping die. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] In the processing and production of auto parts, punching of rolling parts is often involved. In the punching process, when the rolling parts break, the hydraulic machine suddenly unloads and loses the load, so that the load of the workpiece disappears suddenly. The liquid compression energy in the oil cylinder and the fuselage The elastic deformation can be released sharply, causing the workpiece to suddenly lose control at the moment of fracture, and to ...

[0003] In the processing and production of auto parts, punching of rolling parts is often involved. In the punching process, when the rolling parts break, the hydraulic machine suddenly unloads and loses the load, so that the load of the workpiece disappears suddenly. The liquid compression energy in the oil cylinder and the fuselage The elastic deformation can be released sharply, causing the workpiece to suddenly lose control at the moment of fracture, and to punch down at a great speed, which will have a huge impact on the buffer cylinder. The stamping machine will not only produce huge and strong bounce, shock and vibration, but will noise, and cause damage to both the punching machine and the mold, which seriously affects the accuracy and service life of the punching machine. Therefore, we propose a punching device with a buffer structure
