Description

A waste discharge device for a stretching machine

Technical Field

The utility model relates to the technical field of stretching machines, in particular to a waste material discharging device for a stretching machine.

Background Art

Hydraulic stretching has the characteristics of convenient processing and easy forming of parts with special shapes. At present, many thin plate forming products are processed by hydraulic stretching. During the working process of the stretching machine, cutting waste will be continuously produced. If these cutting wastes cannot be discharged, it will cause blockage and mold smashing, affecting the normal operation of the equipment. In severe cases, it may cause the stretching machine to stop.

At present, a waste blowing and discharging device for a stretching machine announced by a Chinese patent with a publication number of CN210652031U includes: a stretching machine cover, a blowing device, a waste discharge pipe, a waste collection box, a negative pressure pump and a wheel. The stretching machine cover includes a cover top plate, a cover side plate and a cover back plate. The inner wall of the cover side plate is provided with a vertically extending slide rail, and the cover back plate is provided with a waste discharge port. The blowing device can slide up and down in the slide rail and can rotate through a slider and a rotating shaft. One end of the waste discharge pipe is connected to the waste discharge port, and the other end of the waste discharge pipe is connected to the top of the waste collection box. The negative pressure pump is connected to the inside of the waste collection box. The stretching machine cover is covered on the outside of the stretching machine, and the blowing device is used to blow the waste and debris generated on the stretching machine in the direction of the waste discharge port. The negative pressure pump generates negative pressure in the waste collection box and the waste discharge pipe, and the waste of the stretching machine is discharged to the waste collection box under the action of the airflow. It is easy to use and can discharge the waste of the stretching machine in time.

In actual use, it is found that the blowing device of the existing equipment can only be adjusted manually, and the position after adjustment is a fixed setting, which results in a limited blowing range of the blowing device on the debris generated on the stretching machine, and the debris on the stretching machine cannot be completely blown into the waste discharge port.
