Description

Technical Field

[0001] This invention relates to the field of Hall effect stents, and in particular to a manufacturing process for Hall effect stents. Background Technology

[0002] To install the Hall sensor, a corresponding Hall bracket needs to be designed, and the Hall sensor is mounted on the Hall bracket using bolts.

[0003] If multiple Hall sensors are to be installed on the Hall bracket, multiple threaded holes need to be machined. These holes require punching or drilling, followed by tapping, a cumbersome process that also imposes requirements on the material thickness of the Hall bracket, increasing costs. Using thin steel plates of 1-2mm thickness for Hall bracket production could be considered, but to ensure structural strength, the Hall bracket's structure is irregular, increasing production difficulty. Conventional welding production is also costly and requires improvement. Summary of the Invention

S2, Surface Treatment Grind the flat blank to remove burrs from the edges, positioning holes, and mounting holes; S3, bending The flat blank is bent using a bending machine. First, the fixed foot plate is bent outward at the bottom of the support plate, and then the reinforcing rib plate and support plate are bent downward to obtain a semi-finished product. S4, Press Riveting A positioning block corresponding to the substrate is installed on the riveting equipment. The positioning block has an indented groove located below the positioning hole. First, the riveting nut is placed on the indented groove, and then the semi-finished product is placed on the positioning block so that the top of the riveting nut enters the positioning hole. The pressure head is used to press down on the area of ​​the substrate corresponding to the positioning hole to realize the riveting fixation of the riveting nut.

[0009] In a preferred embodiment of the present invention, the reinforcing rib plate adopts a long strip structure.

[0010] In a preferred embodiment of the present invention, the support plate adopts a trapezoidal structure.

[0011] In a preferred embodiment of the present invention, the fixed foot plate is perpendicular to the support plate, and the base plate is perpendicular to the support plate.

[0012] In a preferred embodiment of the present invention, the length of the upper part of the positioning block corresponds to the spacing between the reinforcing ribs at the front and rear ends of the substrate.

[0013] In a preferred embodiment of the present invention, the width of the upper part of the positioning block corresponds to the spacing between the support plates at the left and right ends of the substrate.

[0014] In a preferred embodiment of the present invention, the pressure head corresponds one-to-one with the positioning hole.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-3 The embodiments of the present invention include: A manufacturing process for a Hall effect support, such as Figure 1 As shown, the Hall bracket includes a base plate 1, a reinforcing rib plate 5, a support plate 2, a press-fit nut 7, and a fixing foot plate 4. The reinforcing rib plate 5 is disposed at the front and rear ends of the horizontal base plate and extends downward. The support plate 2 is disposed at the left and right ends of the base plate 1 and extends downward. The fixing foot plate 4 is disposed at the bottom of the support plate 2 and extends outward horizontally. The base plate 1, the reinforcing rib plate 5, the support plate 2, and the fixing foot plate 4 adopt an integrated structure, which is structurally stable and does not require welding.

[0019] The press-fit nuts 7 are spaced apart on the bottom surface of the base plate 1. The base plate 1 has positioning holes 6 that correspond one-to-one with the press-fit nuts 7, facilitating the press-fitting construction of the press-fit nuts 7. The fixing foot plate 4 has mounting holes 3, facilitating the fixing foot plate 4 to be fixed in the equipment with bolts.

[0020] The production process includes the following steps: S1, stamping A 1.5mm thick strip steel sheet is fed into a progressive die. The progressive die has punching and blanking stations in the forward direction of the strip steel sheet. In one stroke, the positioning holes 6 and mounting holes 3 are punched sequentially, and the base plate 1, reinforcing rib plate 5, support plate 2, and fixing foot plate 4 are cut to obtain a flat blank. Figure 2 As shown; In this embodiment, there are four positioning holes 6, which can accommodate four rivet nuts 7. The positioning holes 6 are arranged in a rectangular array on the substrate 1, achieving a rectangular array distribution of the rivet nuts 7, thus improving construction convenience and positioning accuracy. S2, Surface Treatment Grind the flat blank to remove burrs from the edges, positioning holes 6 and mounting holes 3, to avoid scratching your hands and to facilitate subsequent bending and riveting. S3, bending The flat blank is bent using a bending machine. First, the fixed foot plate 4 is bent outward at the bottom of the support plate 2, and then the reinforcing rib plate 5 and the support plate 2 are bent downward to obtain a semi-finished product, thereby improving the bending strength of the substrate 1. The reinforcing rib 5 adopts a long strip structure and extends along the width direction of the substrate 1, which can improve the bending strength of the substrate 1 in the width direction; the support plate 2 adopts a trapezoidal structure, which is wider at the top and narrower at the bottom, reducing the footprint of the fixed foot plate 4 while improving the bending strength of the substrate 1 in the length direction. It occupies little installation space and is flexible in position. In this embodiment, the fixed foot plate 4 is perpendicular to the support plate 2, and the base plate 1 is perpendicular to the support plate 2. It is necessary to pay attention to the springback problem during the bending process, and reduce the R angle or increase the degree of bending deformation within the allowable range to ensure that the angles of each part are in place after bending. S4, Press Riveting Positioning blocks 8 corresponding to substrate 1 are installed on the riveting equipment, such as Figure 3 As shown, the positioning block 8 has an indented groove 9 located below the positioning hole 6. First, the rivet nut 7 is placed on the indented groove 9, and then the semi-finished product is placed on the positioning block 6, so that the top of the rivet nut 7 enters the positioning hole 6. In this embodiment, the length of the upper part of the positioning block 8 corresponds to the spacing between the reinforcing ribs 5 at the front and rear ends of the substrate 1, and the width of the upper part of the positioning block 8 corresponds to the spacing between the support plates 2 at the left and right ends of the substrate 1, so as to realize the self-positioning of the substrate 1 above the positioning block 8, avoid the misalignment problem between the rivet nut 7 and the positioning hole 6, and facilitate the operation by human hand or robot arm. The pressing head on the riveting equipment is used to press down on the area corresponding to the positioning hole on the base plate 1, thereby achieving the riveting fixation of the riveting nut 7. Figure 1 As shown, the finished Hall bracket is obtained. In this embodiment, the pressure head corresponds one-to-one with the positioning hole, and all the rivet nuts 7 are riveted and fixed simultaneously in one operation, which improves production efficiency.

[0021] In summary, the Hall effect bracket manufacturing process described in this invention enables the production of Hall effect brackets, reduces production difficulty and cost, ensures structural accuracy and stability, and eliminates the need for welding, thereby improving production efficiency and environmental friendliness.
