The invention discloses a novel method for manufacturing a base and a bracket of a stapler. The method comprises the following steps of: manufacturing the base by a steel plate cold stamping process, and forming a square hole at the position of a central line at one end of the base; and converting materials at the position of the square hole into two symmetrical brackets by a flanging process while the square hole is formed, cutting a part of the materials at the position of the central line of the base at one end of the bracket by a cold cutting method, separating the cut materials from the base partially, and pressing the separated part upwards to form a return spring.
Description
technical field [0001] The invention relates to a manufacturing method of a stapler base and a bracket, in particular to a manufacturing method of a novel stapler base and a bracket, and belongs to the technical field of stationery. Background technique [0002] At present, it is known that the base, the bracket and the return spring of the stapler are separate structures, and after being manufactured independently, they are then riveted and installed and fixed on the base. The structure of this independent structure has many manufacturing processes, The defects of complex manufacturing process, low material utilization rate and high cost. Contents of the invention [0003] The purpose of the present invention is to: provide a novel stapler base and a manufacturing method for the bracket, which overcomes the problems of many manufacturing processes, complicated manufacturing processes, low material utilization rate and high cost brought by the existing stapler. defect. ...
