A small portable two-way retractable stamping device

Abstract

The invention discloses a small portable two-way telescopic stamping device. The device comprises a bottom blocky shell, a middle supporting shell arranged on one side of the upper surface of the bottom blocky shell and a top blocky shell; a hollow structure is arranged in the middle supporting shell, an iron core of which the surface is provided with a coil in a winding mode is fixed to the position, located over the hollow structure, of the middle supporting shell, a storage battery is fixed to the position, located over the iron core, inside the middle supporting shell, and a group of controllers are fixed to the side face of the middle supporting shell. According to the small portable two-way telescopic stamping device, internal hydraulic oil is extruded through the electromagnetic working principle and the principle that like magnetic poles repel each other and unlike magnetic poles attract each other; due to the fact that the transforming speed between the magnetic poles is high and large magnetic force is formed, the formed stamping speed is high, and the stamping power is high; in addition, due to the fact that the device achieves two-way stamping, the relative speed of an upper die block and a lower die block at the contacting moment is 1-2 times that of a one-way stamping device, and then the stamping range of the device is effectively widened.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a small portable bidirectional telescopic stamping device. Background technique [0002] my country's patent number CN200920185956.8 discloses a safety device for small stamping equipment, which is used for small stamping equipment, including an adapter block arranged at the output end of the piston rod of the stamping equipment, and a groove rotatably arranged on the adapter block. A pulley, a curved groove type sliding crank rod that is rotatably connected to the body of the stamping equipment at one end, and a stopper fixedly arranged at the other end of the curved groove type sliding curved rod, and the grooved pulley is installed on the In the curved groove of the curved groove type sliding curved rod. The utility model solves the problems in the prior art, and provides a small stamping equipment safety device which is simple in structure, economical and practica...

AI Technical Summary

Problems solved by technology

[0003] Obviously, the above-mentioned device is a single-pass stamping device. When stamping, the instantaneous contact speed of the two sets of stamping dies is limited, so the stamping force is limited and the stamping range is also limited.
