multifunctional scissors

Abstract

The invention discloses a multifunctional scissors machine. The multifunctional scissors machine includes a short spring welding device and a scissors device which are matched in sequence. The short spring welding device includes a spring feeding port, a feeding guide rail and a spring discharging port arranged in sequence; the scissors device includes a frame, and the frame is provided with a scissors seat and a lifting frame; the scissors seat is provided with an ultrasonic pressing table and a blade, and the ultrasonic pressing A knife track groove runs through the middle of the table, and the blade and the knife track groove are slidably matched. In the present invention, the semi-finished spring material to be processed is compressed and sent to the conveyor belt processing part by setting the feeding guide rail, the cloth at both ends of the spring material is welded by the ultrasonic welding head, and the spring is stretched by its own elastic force to open the cloth to realize the tight wrapping of the cloth. The scissors seat, ultrasonic pressing table and ultrasonic welding table are set to thicken the suture gap; since the blade is set in the middle of the ultrasonic pressing table, it is ensured that the cutting point is the middle line of the welding and suture gap, which ensures that the suture will not be damaged, and the yield is guaranteed.

Description

technical field [0001] The invention relates to the field of spring processing, in particular to a multifunctional scissors machine. Background technique [0002] Spring is a commonly used part. In the spring bed, the spring is usually wrapped with cloth. However, in the current production process of the cloth wrapped spring, affected by the processing technology, the cloth wrapped with the spring is not tight enough, which may easily cause the cloth and the spring to be misaligned; especially for short The wrapping of the spring, because the length of the short spring is shorter, the wrapped cloth is less likely to form a tight wrap. [0003] In the current spring production process, the assembly line usually wraps multiple springs in sequence to form a long strip of spring material. A dividing line is stitched between each spring of the long strip of spring material to ensure that each spring is individually wrapped. However, the actual demand The length of the spring mat...

Problems solved by technology

[0004] When cutting spring materials at present, because the stitching gap between the cloth-wrapped and separated springs is small, it is easy to cut the stitching gap during cutting, making the spring exposed and unusable. The existing cloth wrapping process and material transmission process cannot achieve Very precise cutting control, resulting in more defective products, to achieve precise transportation control and cutting control requires a huge additional cost
