Description

Technical Field

[0001] The utility model relates to the technical field of trimming, and more specifically, to a trimming device for processing fastener products. Background Technique

[0002] The trimming device can accurately cut the edges of fastener products, ensuring the dimensional accuracy and shape consistency of the products, thereby improving the overall quality of the products. Secondly, during the production process of fasteners, burrs may be generated on the edges. These burrs not only affect the appearance of the products but may also have an adverse impact on subsequent use.

[0003] In the existing publicly disclosed technical literature, the patent with the patent announcement number CN104043727A discloses a fastener processing method and device. This device cuts the two sides of the plane where the root of the straight cylinder is located from the intermediate body to form a turning surface that is only connected to the intermediate body on one side of the auxiliary hole. The part between the turning surface and the flank surface is the base surface; the fastener is obtained through multiple bending forming operations. In this way, the strip can be pulsed at adjacent multiple stations in sequence to form the fastener, improving the production efficiency, avoiding the errors brought by the existing processing methods, reducing the production cost, and improving the product quality at the same time. However, this device has the following defects.

[0004] During the use of the device for trimming fastener products, a cutting knife is needed to fit on the edge part of the fastener product to achieve the cutting operation. However, after cutting, the impurities on the trimmed edge will be adsorbed and attached to the edge part of the cutting knife. After each trimming, the cutting knife for trimming needs to be cleaned, resulting in more time-consuming and laborious trimming. Therefore, a trimming device for processing fastener products is needed. Content of the Utility Model
