Automatic clamping device of protection cover for horizontal bunker car carrier roller bearing pedestal for mine

Abstract

The invention belongs to the technical field of mine mechanical manufacturing equipment, and relates to an automatic clamping device of a protection cover for a horizontal bunker car carrier roller bearing pedestal for a mine. An upper mold punch and a rear supply base U groove jointly stamp a plate before an arc plate is bent into an arc plate, a moving stop rod prevents left and right moving, arear supply air cylinder pushes a post-stack seal plate, a rear seal plate on the most-front position is tightly attached to the rear side face of an upper mold, a rear lower pushing air cylinder drives a rear lower pushing plate to downward push a rear seal plate to be matched with the arc plate, a front supply air cylinder pushes a pre-stack seal plate, a front seal plate on the most-front position is tightly attached to the front side face of the upper mold, a front lower pushing air cylinder drives a front lower pushing plate to downwards push a front seal plate to be matched with the arcplate, the automation degree is improved, the labor intensity is reduced, work efficiency is improved, the number of stations is reduced, carrying and transferring steps between the stations are reduced, the work hour is shortened, the occupied workshop space and circulation equipment are reduced, the product size is good in consistency, interchangeability is improved, an welding seal is improved.

Description

technical field [0001] The invention belongs to the technical field of mining machinery manufacturing equipment, and relates to a manufacturing equipment of a horizontal warehouse car for mines, in particular to an automatic clamping device for a protective cover for a bearing seat of an idler roller of a horizontal warehouse car for a mine. Background technique [0002] There are multiple rollers on the horizontal warehouse car for mines, which are used to support the rubber conveyor belt and the weight of the materials carried on it. The idler roller is one of the most important components of the horizontal warehouse car. The idler roller includes a bearing seat, and a ball bearing is arranged in the bearing seat, and the bearing seat is an important part on the idler roller. There is a lot of water in the production site of the mine, and the water will cause the ball bearing to be damaged prematurely. Therefore, a bearing seat shield 1 is installed around the bearing seat...

AI Technical Summary

Problems solved by technology

After the arc-shaped plate 11 is removed from the punch press, it cannot maintain a completely consistent draft angle, and there is a certain springback angle, which cannot be completely resolved even if the overpressure method is used. Need other equipment to be calibrated before it can be used, adding calibration steps and calibration equipment

The traditional manufacturing process has low work efficiency and many stations. The handling and transfer between stations takes up more man-hours, workshop space and turnover equipment. The labor intensity is high, the size is not completely uniform, the interchangeability is poor, and sometimes the welding sealing is not good. It is easy to flow in and pour water, and then it will penetrate into the ball bearing and shorten the service life of the ball bearing
