Hall chip forming tool

Abstract

The invention discloses a Hall chip forming tool comprising an upper die holder, a lower die holder, a plurality of guide pillars and a feeding guide slot, wherein the upper die holder and the lower die holder are respectively provided with an upper die block assembly and a lower die block assembly; the upper die block assembly comprises an upper die fixing block, an upper blade and an upper die pressing block; the lower die block assembly comprises a lower die fixing block, a lower blade, a lower die pressing block and a lower die forming block; the end of the lower die fixing block is provided with a hinge and a cam, and the cam is right positioned under the hinge to be matched with the hinge; and the upper die holder is provided with an air cylinder, and a piston rod of the air cylinder is fixedly connected to the upper surface of the upper die holder. The Hall chip forming tool disclosed by the invention adopts a once fixation and multi-forming mode so as to avoid the damage to a chip part and a capacitor part. The structure of the Hall chip forming tool is once fixed by adopting a spring buffering method so as to prevent a Hall chip pin from being pressed to be transformed. In addition, the Hall chip forming tool disclosed by the invention adopts a hinge structure to assist 90 DEG forming, so that the production efficiency is enhanced.

Description

technical field [0001] The invention relates to the field of Hall chip production and processing equipment, in particular to a Hall chip molding tool. Background technique [0002] The Hall effect is a magnetoelectric effect, which was discovered by the German physicist Hall in 1879 when he studied the nature of the force on a current-carrying conductor in a magnetic field. According to the Hall effect, people use semiconductor materials to make Hall elements. It has the advantages of sensitivity to magnetic field, simple structure, small size, wide frequency response, large output voltage change and long service life. Therefore, it is widely used in measurement, automation, computer and Information technology and other fields have been widely used. [0003] In recent years, with the development of the automobile industry, Hall devices have been widely used in the field of auto parts. The output of Hall devices is directly interfaced with the electronic control unit to ...

Problems solved by technology

[0007] The purpose of the present invention is to provide a Hall chip forming tool, which is used to bend and cut the Hall chip by one-time fixing and multiple forming methods, so as to solve the need for secondary fixing and two-time forming in the existing bending forming device. The secondary molding production method is easy to increase the deformation of the Hall chip during the transfer process, resulting in damage to the capacitor part and the chip part of the Hall chip; at the same time, the spring support method is used for the upper and lower fixing blocks, which increases the upper and lower parts. The stroke of the fixed block is used to slow down the running speed of the upper and lower fixed blocks, so as to reduce the possibility of pin deformation during the Hall chip fixing process; in addition, when forming the Hall chip foot, use the Hall chip pin Due to the weak stress at the hole, the hinge structure is adopted to reduce the production process and improve production efficiency.
