Ultrasonic-assisted stamping device with overload buffering protection function

Abstract

An ultrasonic auxiliary punching device with a buffering overload protection function comprises a hydraulic punching machine, an ultrasonic generator, an ultrasonic vibration assembly, a punching head and a punching die, a mounting hole is vertically formed in the center of a punching lifting platform of the hydraulic punching machine, and the ultrasonic vibration assembly is arranged in the mounting hole and fixedly connected with the punching lifting platform through a bolt assembly; the lower end of the ultrasonic vibration assembly extends downwards out of the stamping lifting platform, a buffering overload protection mechanism is arranged on the lower portion of the hydraulic stamping machine, a stamping workbench of the hydraulic stamping machine is arranged on the top of the buffering overload protection mechanism, a replaceable stamping die is arranged on the stamping workbench, and a stamping head is arranged at the lower end of the ultrasonic vibration assembly and located over the stamping die. The ultrasonic generator is connected with the ultrasonic vibration assembly through a wire. According to the ultrasonic vibration additional stamping head, the quality and precision of a stamped workpiece are improved, the die is rapidly reset after stamping, discharging is convenient, meanwhile, overload protection is achieved for an ultrasonic vibration system, and safe stamping operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of punching machinery and equipment, in particular to an ultrasonic auxiliary punching device with buffer overload protection. Background technique [0002] In the industrial production process, the stamping process has the advantages of saving materials and energy, and high efficiency compared with traditional casting. It does not require high technical requirements for operators, and can obtain the advantages of workpiece products that cannot be achieved by mechanical processing. Therefore, its use is becoming more and more. more extensive. Stamping production is mainly for sheet metal parts. Through the stamping die, blanking, punching, forming, stretching, trimming, shaping, riveting and extrusion can be realized, and are widely used in various fields. For example, many accessories such as switches, cups, mobile phone casings, computer casings, car casings, and even aircraft, missiles, etc. can be prod...

AI Technical Summary

Problems solved by technology

The finished workpiece of the current stamping machine is closely attached to the mold, and the separation between the two is basically done manually. It is very difficult for manual labor and may even damage the processed workpiece, and the labor intensity of the workers is very high. It is not conducive to improving the production efficiency of enterprises

[0003] In the daily production of enterprises, workpiece shapes of different specifications may be required, but the purchase cost of molds is high and the purchase cycle is long. Purchasing multiple types of molds with different specifications of molds is not conducive to improving the economic income of enterprises

The molds designed and produced by the enterprise itself are not conducive to the separation of workers and workpieces. It is time-consuming and laborious, and it is easy to damage the quality of the processed workpieces and reduce the production efficiency of the enterprise.

[0004] In some fields, high-quality, high-quality comprehensive performance products are emphasized, but the quality is difficult to guarantee, and high-quality, high-precision, long-life products are usually expensive, which is not convenient for enterprise development and limits the scope of application of products
