Auxiliary grabbing punching device for blister lining

Abstract

The invention discloses an auxiliary grabbing punching device for a blister lining, and relates to the technical field of punching equipment. The auxiliary grabbing punching device for the blister lining comprises an L-shaped mounting frame; the L-shaped mounting frame comprises a horizontal plate and a vertical plate which are fixed to each other; a first air cylinder is fixedly mounted on the upper surface of the horizontal plate; a piston rod of the first air cylinder penetrates through the horizontal plate and is connected with a movement frame; and a safety pin mechanism is fixedly mounted on one side surface, far away from the movement frame, of the vertical plate. According to the auxiliary grabbing punching device for the blister lining, the first air cylinder drives a mounting frame to drive a #-shaped rail frame to ascend and descend, and an adsorption point of the blister lining is adsorbed through the action of a sucking disc component, so that the blister lining is pressed; the punching precision of a punching head mechanism is improved; the punched blister lining is driven to ascend through the sucking disc component so as to facilitate the taking of people and reducethe operation risk of people; moreover, the collision and strain deformation of the blister lining are avoided; and the safety and the use performance of the blister lining are ensured.

Description

technical field [0001] The invention belongs to the technical field of punching equipment, and in particular relates to an auxiliary grasping punching device for a blister lining. Background technique [0002] At present, in the refrigerator industry, before the refrigerator is pre-installed, it is necessary to punch holes in the parts of the blister lining that need to be threaded or plugged. For the lining that is not suitable for the blister-punching line After completion, it is manually transported to the punching station, and then the inner lining is punched by a manual punching machine; [0003] Nowadays, using a special punching machine to punch the inner liner requires workers to carry the inner liner into the punching equipment, place the inner liner accurately on the punching positioning point, and take it out after the punching is completed; Under this traditional method, workers need to put their upper body into the punching machine when taking out the lining, w...

Problems solved by technology

[0003] Nowadays, using a special punching machine to punch the inner liner requires workers to carry the inner liner into the punching equipment, place the inner liner accurately on the punching positioning point, and take it out after the punching is completed; In this traditional method, workers need to put their upper body into the punching machine when taking out the lining, which increases the risk of workers' operation

And because the lining is often tightly attached to each positioning structure of the punching machine due to the punching pressure after punching, it greatly increases the difficulty for workers to take out the lining. For larger and heavier linings, Scratches on the inner wall and bump marks caused by pulling often occur during the removal process

At the same time, during the punching process, the back of part of the inner lining could not fully fit the positioning surface of the special machine due to reasons such as improper molding, resulting in a lack of punching accuracy.

[0004] Part of the special punching machine adopts the method of installing a mechanical ejector device on the die or positioning part. Although this method can facilitate the removal of the inner lining, it will cause strain and deformation of the inner lining due to uneven force, and it cannot completely solve the problem of workers removing the inner lining. The defect of putting the upper body into the punching machine when lining
