Abstract

The invention belongs to the technical field of punching and manufacturing of metal plates and particularly relates to a stabilizing pin for a formed metal plate. The stabilizing pin is characterized by comprising a carrier, a conical head threaded rod and a locating pin, a threaded hole and a locating pin mounting hole are formed in the axial direction of the carrier, the locating pin mounting hole is formed in an eccentric mode, a step table is arranged in the locating pin mounting hole, the locating pin enters the locating pin mounting hole from the bottom of the carrier and is fixed through a screw plug, a cavity is formed in the back of the locating pin, a spring is arranged in the cavity, the bottom of the spring abuts against the screw plug, the side face of the carrier is provided with a steel ball mounting hole, the steel ball mounting hole is communicated with the threaded hole, and the front face of the conical head threaded hole is screwed into the threaded hole and tightly presses a steel ball arranged in the steel ball mounting hole. The stabilizing pin for the formed metal plate is simple in structure, convenient to install, capable of effectively solving the problem that a part formed through stretching jumps on a blank holder, and capable of improving the debugging efficiency of a die and ensuring the punching stability of the die.

Description

technical field

[0001] The invention belongs to the technical field of stamping and manufacturing of sheet metal, and in particular relates to a stabilizer pin after forming of sheet metal. Background technique

[0002] When stamping, especially in automatic production, it is necessary to install positioning pins on the mold. The positioning pins need to be stuck on the edge of the stamping parts to prevent the parts from moving on the mold after forming, so as to obtain a stable position of the parts on the mold. , so as to meet the requirements of the automatic robot to send the parts to the subsequent mold according to the expected position, to ensure the normal operation of the stamping production, and to obtain products with stable dimensions. After the blank is drawn and formed, the boundary of the part needs to be restricted, but the drawn part boundary line cannot be accurately measured, and it needs to be determined through repeated experiments during the mold debug...
