Shear mechanism for cutting spiral coil and then bending countersink head

Abstract

The invention discloses a shear mechanism for cutting a spiral coil and then bending a countersink head. The shear mechanism comprises an L-shaped fixing plate, and is characterized in that a slide rail is fixed to the front side surface of the transversal part of the L-shaped fixing plate, and a spiral coil location frame is fixed to the outer side of the longitudinal part of the L-shaped fixingplate; a working groove is formed in the side of the spiral coil location frame, a through groove allowing the spiral coil to penetrate through is formed in the bottom side of the spiral coil locationframe, and tooth grooves allowing the spiral coil to be correspondingly embedded and located are formed in the two side surfaces of the port of the through groove; a connection arm is fixed to the slide block of the slide rail, and a cutting knife group for cutting the spiral coil and then bending the countersink head is installed on the connection arm; and the bottom of the cutting knife group is inserted into the working groove, and cuts the spiral coil and then bends the countersink head after working. The structure completes the action of cutting, bending and safe hooking-back simultaneously, thereby increasing the working efficiency during production, and improving the safe use performance of the product.

Description

technical field [0001] The invention relates to the technical field of a metal helical coil shearing mechanism in the bookbinding industry, in particular to a scissors mechanism for bending a hidden head after cutting the helical coil. Background technique [0002] At present, in the bookbinding industry, for the bending and hiding process of the spiral (single) coil, what can be done on the equipment is only to manually bend the end of the spiral coil after cutting. However, the artificially bent metal wire is irregular, affecting the appearance, low work efficiency, and unsafe. The coil binding process must be processed with safety hooks. At present, the only method that various enterprises in this book industry can adopt is manual safety hooking, which leads to low efficiency, irregularity and instability in the production process. It is imperative to use mechanical equipment for bending and safety hook processing. Contents of the invention [0003] The purpose of th...
