Problems solved by technology

The problem that this existing cutting device exists is: in order to reach the smoothness of loading and unloading, need leave larger gap between the product piece of automobile door glass guide rail and the cutting edge of lower static knife, but if the gap is bigger, the automobile door glass The deformation of the guide rail near the cutting position will also increase, and the tolerance requirements of the product parts cannot be guaranteed; while reducing the gap and ensuring the tolerance requirements of the product parts, the automatic return function cannot be realized
Therefore, it is difficult for the current cutting device to take into account the dual requirements of improving the processing quality of the product and automatically returning the material

Abstract

A cutting-off and material returning device for cutting off automobile door glass guide rails comprises a base, a clamping mechanism, a cutting-off mechanism and a material returning mechanism. The clamping mechanism comprises a clamping oil cylinder, a sliding block, a movable clamping block and a clamping assembly. A clamping oil cylinder piston rod is fixedly connected with one end of the sliding block, and the other end of the sliding block is fixedly connected with the movable clamping block through a movable clamping block mounting seat. An upper wedge and a lower wedge are fixed to the upper portion and the lower portion of the movable clamping block correspondingly. The clamping assembly comprises an upper knife, a middle shaping plate and a lower knife. The middle shaping plate is fixed to a mounting frame. The upper knife and the lower knife are connected to the upper portion and the lower portion of the middle shaping plate in a floating mode correspondingly. The front end of the movable clamping block corresponds to the middle shaping plate. The upper wedge and the lower wedge correspond to the upper portion of the upper knife and the lower portion of the lower knife respectively. The cutting-off mechanism comprises a cutting-off oil cylinder and a cutting-off knife. The material returning mechanism comprises a material returning oil cylinder and a material returning rod. According to the cutting-off and material returning device for cutting off the automobile door glass guide rails, structure setting is ingenious, feeding is convenient, material returning is smooth, non-deformation of cut-off products can be guaranteed, and an automatic material returning function can be completed after cutting-off.

Description

technical field [0001] The invention relates to a cutting device for stretch-bending product parts, in particular to a cutting and returning device for cutting the stretch-bending formed automobile door glass guide rail product parts. Background technique [0002] The car door glass guide rail is a product installed on the car door window, which mainly plays the role of sliding guide for the car door glass and installing the sealing strip. In the automotive metal parts processing industry, usually the connected left and right car door glass guide rails are stretch-bent and formed, and then the left and right car door glass guide rails after stretch-bending are cut to process left and right independent of automotive door glass guide rail products. Existing car door glass guide rail cutting device such as Figure 9 As shown, the device is powered by an oil cylinder, and the oil cylinder, lower static knife, and moving knife mounting block are installed on the mounting plate. ...
