Embodiment Construction

[0012] The present invention includes the work roll 1 of the plate rolling machine, the dumping bearing body 2, and the column pin 4, and is characterized in that the column pin 4 has a loading and unloading groove 5, and the depth of the loading and unloading groove 5 is greater than the height h of the arcuate body groove on the working roll 1, loading and unloading The length of the groove 5 is greater than the length a of the arch groove on the work roll 1 .

[0013] Column pin 4 outer end also has rotating handle 6, can rotate column pin 4 conveniently.

[0014] When the plate rolling machine is working (see Figure 5-6 ), the work roll 1 of the plate rolling machine and the dumping bearing body 2 are connected by the pin 4; when the workpiece needs to be taken out (see Figure 7-8 ), only need to rotate the column pin 4 at a certain angle to separate the dumped bearing body 2 from the work roll 1, tilt the bearing body 2 by 90°, and take out the cylindrical workpiece ro...

Abstract

The invention relates to a toggle positioning mechanism for lapping machines, in particular to a toggle positioning mechanism for medium and small lapping machines, which comprises working rollers of a lapping machine, a pouring bearing body and a dowel pin, and is characterized in that the dowel pin is provided with an assembling and disassembling tank, the depth of the assembling and disassembling tank is greater than the height of the bow-shaped tank on the working rollers, and the length of the assembling and disassembling tank is greater than that of the bow-shaped tank on the working rollers. The toggle positioning mechanism reduces the labor intensity of the medium and small tri-roller lapping machines during the pouring and resetting of the toggles, and enhances the reliability.

Description

technical field [0001] The invention relates to an inverted positioning mechanism of a plate rolling machine, in particular to an inverted positioning mechanism of a small and medium-sized plate rolling machine. Background technique [0002] At present, the structure of dumping and resetting the small and medium-sized three-roller plate bending machine in China is connected by a column pin. When the plate bending machine is working (see Figure 1~2 ), the work roll 1 of the plate rolling machine and the dumping bearing body 2 are connected by the pin 3; when the workpiece needs to be taken out (see Figure 3-4 ), the dumping bearing body 2 must be separated from the work roll 1, and the column pin 3 must be pulled out along the right direction before the rolled cylindrical workpiece can be taken out. Therefore, the operation is laborious and the reliability is poor. Contents of the invention [0003] The purpose of the present invention is to provide a small and medium-si...
