Problems solved by technology

Since the safety bolt has a large structure and weighs about 30kg in order to meet the supporting load, the operator needs to place four safety bolts between the upper and lower molds, which is not only labor-intensive, but also inefficient in the arrangement of safety bolts

Embodiment Construction

[0011] A limit device, comprising a connecting arm 10, one end of the connecting arm 10 is hinged to the column 1 of the press and the axis of the hinge axis is located in the vertical direction, the other end of the connecting arm 10 is connected to the supporting column 20, and the column length of the supporting column 20 is located in the vertical direction. In the vertical direction, the connecting arm 10 rotates around the hinge axis so that the support column 20 is located between the upper and lower molds 2 and 3 or at an avoidance position of the lower mold 3 moving path.

[0012] In this application, the connecting arm 10 connected with the support column 20 is directly hinged with the press column 1, the structure is simple, and the layout is convenient. It can play the role of supporting the upper mold 2 without the need for workers to carry the support column 20 back and forth, which reduces the labor intensity of the workers and improves the arrangement efficiency...

Abstract

The invention discloses a limiting device. The limiting device comprises a connecting arm. One end of the connecting arm is hinged to a pressing machine vertical column, and the axial direction of a hinged shaft is located in the vertical direction. The other end of the connecting arm is connected to supporting columns. The length directions of the supporting columns are located in the vertical direction. The connecting arm rotates around the hinged shaft to enable the supporting columns to be located between an upper mold and a lower mold or located at an avoiding position of the moving pathof the lower mold. A worker directly rotates the support columns around the hinged shaft to the position which is between the upper mold and lower mold around the hinged shaft, the labor intensity ofthe worker is greatly reduced, and the efficiency of the arrangement of the support columns is significantly improved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a limiting device for limiting the relative positions of upper and lower dies. Background technique [0002] A mold usually includes an upper mold and a lower mold that cooperate with each other. In the stamping forming process, when the upper and lower molds are separated up and down, the blank to be formed is placed between them. After the upper and lower molds are closed, the blank is formed into the desired shape, and the upper and lower molds are separated to take out the formed part. When the mold is in the storage area or during non-working hours, the upper and lower molds do not need to be fully clamped, but a columnar safety bolt is placed between the clamping surfaces of the upper and lower molds, and the safety bolt is fixed on the side of the press. On the four uprights, when in use, the electrical interlock plug should be pulled out to ensure that the producti...
