Supporting plate mechanism capable of being additionally installed on general plate shearing machine and used for positioning corner shearing of rectangular plate

Abstract

The invention relates to a supporting plate mechanism capable of being additionally installed on a general plate shearing machine and used for positioning the corner shearing of a rectangular plate. The supporting plate mechanism comprises a bedplate fixed on the plate shearing machine, and is characterized in that at least two sets of positioning structures are fixed on the bedplate; each set ofpositioning structure comprises two pairs of electric telescopic rods; the rod parts of one pair of electric telescopic rods limit one side edge of the rectangular plate, the rod parts of the other pair of electric telescopic rods limit another side edge of the rectangular plate, and the two side edges are adjacent; each pair of electric telescopic rods comprises at least two electric telescopic rods fixed at the bottom of the bedplate; and the rod part of each electric telescopic rod can extend upwards out of the top surface of the bedplate or retract downwards to be hidden below the top surface of the bedplate. According to the supporting plate mechanism, the positioning size is stable and accurate, the corner shearing speed is greatly increased, the corner shearing is not influenced byon-site light, and people do not need to visually observe whether the line drawing positions are aligned with the edges of the plate or not, so that the foolproof operation is realized, and the working efficiency of plate shearing is greatly improved.

Description

technical field [0001] The invention relates to an auxiliary device of a shearing machine, in particular to a supporting plate mechanism which can be installed on a general-purpose shearing machine for positioning the shearing angle of a rectangular plate. Background technique [0002] The sink is formed by stretching the sheet. In order to prevent stress cracking during the stretching process in the sink industry, it is generally necessary to cut the corners of the right angles of the rectangular sheet multiple times, which can be cut twice. Generally, the corners are cut at most three times, and then stretched to eliminate the stress concentration at the corners of the rectangular sheet and prevent cracking and whitening during the stretching process. The traditional old method is the line drawing method. [0003] In the actual operation process of the traditional line drawing method, the edge of the plate is limited by factors such as workers, the size of the plate, and t...

Problems solved by technology

[0003] In the actual operation process of the traditional line drawing method, the edge of the plate is limited by factors such as workers, the size of the plate, and the light on site, and the error size is relatively large; each operation must be aligned with the edge of the plate with the naked eye , the operating efficiency is also low

Compared with traditional sink stretching, dishwasher sink stretching not only has a deeper stretching depth, but also has much higher dimensional requirements. Therefore, the precision of the cutting angle of the plate is also higher, and the traditional line drawing method cannot meet the requirements at all.
