A precision punching equipment for processing automobile door hinges

Abstract

The invention discloses a precision punching equipment for processing automobile door hinges, which comprises a base, a cylinder is fixedly installed on the upper end of the base, a filtering mechanism is arranged inside the cylinder, and a filter mechanism is arranged inside the cylinder. A protective machine cover is fixedly installed at the center of the cavity, a clamp assembly is arranged on the upper end of the protective machine cover, and a drain pipe is fixedly installed on the outer front of the cylinder. The precision punching equipment used for the processing of automobile door hinges according to the present invention, through the installed filter mechanism and filter tube, the filter mechanism can block some larger metal debris, and it is also convenient for the staff to take it out for replacement and cleaning , and the magnet inside the filter tube can absorb fine metal debris to the filter net, so that it is convenient for the staff to clean up, and the metal content of the sewage filtered by the filter mechanism and the filter tube is less, thereby reducing the difficulty of subsequent sewage treatment.

Description

technical field [0001] The invention relates to the technical field of precision punching equipment, in particular to a precision punching equipment used for processing automobile door hinges. Background technique [0002] The car door hinge is mainly installed between the car door and the car body to ensure the rotation of the car door, and the door hinge will need a precise punching device to process and drill the hole during the processing process, because the door hinge is a bit rough during the processing process. Small errors will lead to different sizes of hinge holes, which will affect the processing and subsequent use of the entire hinge, and if the torque of the hole drilled by the hinge is large during the production process of the hinge, it will cause the punching drill to collapse, so now the car The hinge punching devices in the production workshop are relatively accurate. [0003] However, the current precision punching equipment for automobile hinge processi...

Problems solved by technology

[0002] The car door hinge is mainly installed between the car door and the car body to ensure the rotation of the car door, and the door hinge will need a precise punching device to process and drill the hole during the processing process, because the door hinge is a bit rough during the processing process. Small errors will lead to different sizes of hinge holes, which will affect the processing and subsequent use of the entire hinge, and if the torque of the hole drilled by the hinge is large during the production process of the hinge, it will cause the punching drill to collapse, so now the car The hinge punching devices in the production workshop are relatively accurate

[0003] However, the current precision punching equipment for automobile hinge processing will produce a large amount of metal debris during use, and the metal debris produced will stay on the punching equipment for a long time, which will affect the use of the punching device, and the falling The metal debris is inconvenient for the staff to clean up, and the metal debris falling from processing will be discharged along with the cleaned sewage without cleaning, which will increase the difficulty of subsequent sewage treatment;

[0004] Moreover, when the precision punching device is in use, the piston rod that stretches back and forth will be washed by cooling water for a long time, which will affect the accuracy of the entire punching device, and the sewage on the surface of the piston rod cannot be cleaned in time every time it is used, which will lead to insufficient surface of the piston rod. The smoothness, thus affecting the service life of the piston rod
