Description

Technical Field

[0001] The utility model relates to the technical field of hot riveting equipment, in particular to a hot riveting head of hot riveting equipment for automobile sensors. Background Art

[0002] During the hot riveting process, the material is first heated to above its softening point in order to form the desired shape under pressure. The material then needs to be cooled to solidify its shape and maintain the desired properties. The cooling rate is one of the key factors affecting the final performance of the material. After hot riveting, in order to quickly cool the product to room temperature for subsequent processing or treatment, air blowing is an efficient method. During air blowing, blowing air into the hot riveting head can accelerate heat dissipation, shorten the cooling time, and thus improve production efficiency. In addition, an appropriate cooling rate is crucial to ensuring the molding quality of the hot riveting head, especially the hot riveting head made of PBT-GF30. By controlling the cooling rate, the product can be crystallized and solidified under optimal conditions, reducing the generation of internal stress and defects, and improving the overall quality of the product.

[0003] After traditional hot rivet studs are heated and pressed into shape, they cannot be cooled quickly during the air-blowing cooling process, resulting in carbonization, whitening, and wire drawing of the product rivet heads (especially PBT-GF30 hot rivet studs). This places high demands on parameter debugging. In addition, since existing hot rivet heads generally have a large through-hole in the head for ventilation cooling during cooling, the head is easily deformed by pressure during hot riveting, resulting in the need for frequent replacement of the hot rivet heads. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a hot rivet head of a hot riveting device for an automobile sensor, which can realize rapid cooling of the hot rivet head, reduce the generation of internal stress and defects in the hot rivet head, and improve the overall quality of the product.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows.

[0006] A hot rivet head for hot riveting equipment of automobile sensors includes a hot rivet head body, a hot rivet head body head portion arranged at the lower end of the hot rivet head body, and a hot rivet head body tail portion arranged at the upper end of the hot rivet head body; the hot rivet head body head portion is provided with a plurality of air blowing cooling channels arranged at even intervals, and the air blowing cooling channels are provided through the hot rivet head body head portion.

[0007] The above-mentioned hot rivet head of the hot riveting equipment for automobile sensors has a head end portion of the hot rivet head body provided with an inwardly recessed groove for shaping the product rivet head.

[0008] The above-mentioned hot riveting head of the hot riveting equipment for automobile sensors has a threaded hole on the tail of the hot riveting head body, and the hot riveting head body is threadedly connected to the hot riveting equipment through the threaded hole.

[0009] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is as follows.

[0010] The utility model provides a hot rivet head for hot riveting equipment of automobile sensors. By opening a plurality of groups of air blowing cooling channels which are set through and evenly arranged in the head of the hot rivet head body, the hot rivet head is quickly cooled, thereby realizing rapid temperature reduction of the hot rivet head, avoiding carbonization, whitening and wire drawing of the product rivet head, enabling the product rivet head to crystallize and solidify under optimal conditions, reducing the generation of internal stress and defects, improving the overall quality of the product, and at the same time improving the strength of the hot rivet head and making it less prone to deformation.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0014] A hot riveting head for hot riveting equipment of automobile sensors, such as Figure 1 As shown, it includes a hot rivet head body 1, a hot rivet head body head 3 arranged at the lower end of the hot rivet head body 1, and a hot rivet head body tail 2 arranged at the upper end of the hot rivet head body 1.

[0015] A plurality of evenly spaced air cooling channels 4 are provided on the head portion 3 of the hot rivet head body. The air cooling channels 4 are provided through the head portion 3 of the hot rivet head body. Cold air is blown into the air cooling channels 4 so as to quickly cool the head portion 3 of the hot rivet head body.

[0016] Since the air blowing cooling channels 4 are arranged at intervals through the head portion 3 of the hot rivet head body, the deformation resistance of the head portion 3 of the hot rivet head body is improved, and the head portion 3 of the hot rivet head body is more solid.

[0017] An inwardly recessed groove 5 is provided at the end of the head 3 of the heat rivet head body. The groove 5 is fitted with the heat rivet stud on the sensor and shapes the heat rivet stud. The shape of the groove 5 can be processed according to the desired forming shape of the heat rivet stud.

[0019] During use, the hot rivet head body 1 is threadedly connected to the hot riveting equipment through the threaded hole 6 to preheat the hot rivet head. Then, the hot rivet head body 1 is moved downward so that the groove 5 contacts the hot rivet stud on the sensor so that the hot rivet stud is melted and then pressed down to form. Finally, cold air is blown into the air cooling channel 4 to take away the heat from the head of the hot rivet head body, thereby achieving rapid cooling of the hot rivet head, so that the product rivet head can crystallize and solidify under optimal conditions, reduce the generation of internal stress and defects, and improve the overall quality of the product.
