Abstract
Description
Technical Field
[0001] The utility model belongs to the field of auxiliary equipment for automobile sheet metal processing, and particularly relates to a buffer device for a rear baffle of a swing shear. Background Art
[0002] A swing shear can shear steel plates or aluminum plates to produce various shaped sheets. After the shearing is completed, the sheets need to be conveyed to a stacking area through a conveyor roller path for stacking and packing.
[0003] On a shearing and stacking production line for automobile sheets in our enterprise, a pushing baffle is arranged at the rear baffle of the stacking area. The pushing baffle is driven by an electric push rod and can push and pat the automobile sheets falling on the conveyor roller path to make them flush with the front baffle, so as to adjust the position of the sheets for neat stacking. However, directly pushing and patting the automobile sheets in this way by the pushing baffle easily causes damage to the sheets and reduces the product quality. Summary of the Utility Model
[0004] Based on the defects existing in the existing pushing baffle in the background art during use, the present application provides a buffer device for a rear baffle of a swing shear, which includes a pushing baffle, a bracket, a buffer plate and a buffer spring. The pushing baffle is vertically arranged, and two brackets are respectively and fixedly connected to both sides of the top of the pushing baffle. One end of the buffer plate is hinged between the two brackets, and a buffer spring is fixedly connected to the side of the buffer plate close to the pushing baffle.
[0005] In this way, when the pushing baffle is driven by the electric push rod to push and pat the automobile sheets in the stacking area, the automobile sheet will first contact the buffer plate. Under the action of the impact force, the buffer plate swings towards the pushing baffle, and the buffer spring between the buffer plate and the pushing baffle is compressed to buffer the impact force. In this way, the direct impact between the pushing baffle and the automobile sheet is avoided. Under the buffering of the buffer plate and the buffer spring to the impact force, the damage to the automobile sheet can be avoided and the quality of the automobile sheet can be guaranteed.
[0006] Further, a shock pad is fixedly connected to the center of the side of the buffer plate where the buffer spring is arranged. The shock pad is made of rubber. When the impact force received by the buffer plate is too large and the buffer spring is compressed to the limit, the shock pad can play a role and contact the pushing baffle to further buffer, so as to avoid violent impact between the buffer plate and the pushing baffle.
[0007] Preferably, the buffer plate is a three-layer composite plate including a bakelite plate, a polyurethane plate and an iron sheet. The polyurethane plate is fixedly connected to the side of the bakelite plate away from the pushing baffle, and the iron sheet is coated on the outer side of the polyurethane plate. Such a buffer plate has a certain flexibility and is less likely to damage the automobile sheet.
[0008] Preferably, the bracket is integrally formed by a straight part and a vertical part; an installation hole is provided on the vertical part of the bracket, and a threaded hole is provided on the upper side surface of the push baffle at a corresponding position. After the vertical part of the bracket is attached to the side surface of the push baffle, a bolt passes through the installation hole of the vertical part of the bracket and then screws into the threaded hole of the push baffle to achieve the fixed installation of the bracket, so that the bracket can be firmly installed on the push baffle; a pin shaft is provided between the straight parts of the two brackets, and a bushing is fixedly connected to the top of the buffer plate. The bushing of the buffer plate is sleeved on the pin shaft to achieve the hinge connection of the buffer plate.
[0009] Through the above technical solutions, the present utility model has at least the following beneficial effects:
[0010] The buffer device of the post shear stop of the present application has a simple and delicate structure and can be stably and firmly installed on the push baffle in the stacking area. When the push baffle pushes and pats the automotive sheet falling on the conveyor roller path, the automotive sheet will first contact the buffer plate. Under the action of the impact force, the buffer plate swings towards the push baffle, and the buffer spring between the buffer plate and the push baffle is compressed to buffer the impact force, thus avoiding the direct impact between the push baffle and the automotive sheet. Under the buffering of the impact force by the buffer plate and the buffer spring, the automotive sheet can be prevented from being damaged and the production quality of the automotive sheet can be guaranteed.
