Stamping die with safety protection function

Abstract

The utility model relates to the technical field of metal stamping, in particular to a stamping die with a safety protection function, which comprises a base, supporting legs are fixedly arranged on four sides of the bottom end of the base, a module is fixedly arranged at the top end of the base, and protective plates are fixedly arranged on two sides of the top end of the base. When the metal mesh enclosure needing to be punched is shaped, the air cylinder is started to drive the mounting plate fixed to the top end of the air cylinder to descend, the mounting plate descends to drive the punching machine head at the bottom end of the mounting plate to descend to punch and form a die, however, the punching machine head can be abraded or needs to be cleaned in long-term and massive operation, and therefore the punching machine head needs to be detached and cleaned, and the cost is reduced. At the moment, pull blocks at the two ends of the mounting block are pulled at the same time to enable a pull rod fixed to one end to move, the pull rod moves to drive a clamping block fixed to one end to leave a fixing groove, and therefore the fixed relation between the punching machine head and the mounting block is canceled, the punching machine head can be conveniently taken down to be cleaned, maintained or replaced, the effect is better when the device punches the metal mesh enclosure, and the practicability of the device is improved.

[0003] In a stamping die with a safety protection function, the disclosure specification of the Chinese utility model patent application is CN203400985U. Although it has the advantage of emergency braking of the micro stamping machine in dangerous situations to protect personnel safety, it is not convenient to replace, repair and clean the device, and its braking and buffering effect is not good. Therefore, a stamping die with a safety protection function is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a stamping die with a safety protection function to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, the punching mechanism comprises a cylinder, a mounting plate, a mounting block, a mounting groove, a square groove, a disassembly mechanism, a fixed block, a fixed groove and a punching machine head, a cylinder is fixedly arranged on four sides of the top of the base, a mounting plate is fixedly arranged on the top of the cylinder, a mounting block is fixedly arranged on the bottom of the mounting plate, a mounting groove is provided at the bottom of the mounting block, square grooves are provided at both ends of the mounting groove, a disassembly mechanism is provided in the square groove, a fixed block is provided in the mounting groove, fixed grooves are provided at both ends of the fixed block, and a punching machine head is fixedly arranged at the bottom of the fixed block;

[0009] Preferably, the disassembly and assembly mechanism comprises a through hole, a pull rod, a second spring and a clamping block, a through hole is opened at one end of the square slot, a pull rod is arranged in the through hole, a second spring is fixedly arranged on the outside of one end of the pull rod located inside the square slot, and a clamping block is fixedly arranged on one end of the pull rod located inside the square slot;

[0010] Preferably, the card block is arranged in a single-sided trapezoidal shape;

[0011] Preferably, a pull block is fixedly provided at one end of the pull rod located outside the through hole.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. This stamping die with a safety protection function will start the cylinder when shaping the metal mesh cover to be stamped, driving the mounting plate fixed on its top to descend. The descent of the mounting plate drives the stamping head at its bottom to descend to stamp the die into shape. However, the stamping head will cause wear or need to be cleaned during long-term and large-scale operation, so it needs to be disassembled for cleaning. At this time, the pulling blocks at both ends of the mounting block are pulled at the same time to move the pull rod fixed at one end. The movement of the pull rod drives the fixed block at one end to leave the fixed groove, thereby canceling the fixed relationship between the stamping head and the mounting block, making it convenient to remove it for cleaning, maintenance or replacement, so that the device can have a better effect when stamping the metal mesh cover, thereby enhancing the practicality of the device.

[0014] 2. This stamping die with safety protection function is very easy to injure the operator's hands when an emergency occurs during the operation of the device. Therefore, locking mechanisms are set on both sides of the device. When the device fails, the electromagnetic sheet in the control strip groove will cancel the magnetism at the same time, and the telescopic rod at one end will pop out the strip block fixed at one end under the force of the spring. When the stamping mechanism descends, it will be locked to prevent it from continuing to punch down and causing harm to the operator, thereby improving the safety of the device.
