With the improvement of the current quality of life, metal stamping parts have gone deep into various fields, and it has been closely related to our lives.
The metal stamping parts are made by the stamping process, which is a processing method in which the blank of the workpiece is plastically deformed or separated by the external force exerted by the die, so as to obtain the workpiece with certain size, shape and performance.
The stamping and drawing process should be combined with the actual conditions of equipment and personnel to select and design a process plan with advanced technology, reasonable economy and reliable use.
The following describes the process advantages and manufacturing principles of the next hardware stamping parts:
I. technological advantages of metal stamping parts.
(1) the assembly and repair of metal stamping parts are convenient, convenient and labor-saving.
(2) the shape of the metal stamping parts is simple and the structure is reasonable, which can be beneficial to the manufacture of the die.
(3) hardware stamping parts should be applied to the existing material equipment, process equipment and process flow.
(4) Metal stamping parts can improve the utilization rate of metal materials and reduce the types and specifications of materials.
(5) the metal stamping parts are beneficial to the exchange of the same batch of workpieces and reduce the scrap status.
II. Manufacturing principles of hardware stamping parts.
(1) Precision principle: the number of drawing processes is related to material properties, drawing height, drawing steps, drawing diameter, material thickness and so on.
(2) Fine principle: the number of working procedures of bending parts mainly depends on the messy degree of its structural shape, and depends on the number of bending angles and bending direction.
(3) exquisite principle: when the cross-section quality and standard precision of stamping workpiece are high, consideration can be given to adding dressing process after blanking process or selecting fine blanking process directly.
(4) exquisite principle: when blanking a workpiece with simple shape, you can choose a single-process die, while when blanking a messy workpiece, due to the limitation of the structure or strength of the die, several parts of blanking should be paid dividends on the surface and inside. it is necessary to choose multi-channel metal stamping process.
(5) principle of fine products: in order to ensure the quality of fine metal stamping parts, sometimes the number of processes is needed.
Such as the additional process hole punching of bending parts, the increase of deformation in the forming process to reduce hole blanking to transfer the deformation zone, etc., to ensure the degree of fine and exquisite products.
