Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision machining machinery, and in particular to a high-precision spring forming device for automotive radar. Background Technology
[0002] With the rapid development of automotive intelligence and autonomous driving technology, the precision requirements of key internal components of vehicle radar, as a core sensing component, are becoming increasingly stringent. Among them, high-precision springs used for signal transmission, structural support, and buffer protection directly affect the detection accuracy, stability, and service life of the radar. Conventional mold forming processes have two major technical bottlenecks: first, burrs and dimensional deviations are easily generated during the forming of micro pins; second, angular deviations occur when the spring releases residual stress. Therefore, we propose a high-precision spring sheet forming device for automotive radar. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a high-precision spring sheet forming device for automotive radar. By setting the synergistic effect of punch and bending knife, differential punching technology is used to avoid burr residue. The punching surface is strictly controlled to face downward to ensure angle consistency, making the produced workpieces more precise.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A high-precision spring sheet forming device for automotive radar includes a working mechanism, wherein a blade assembly mechanism is fixedly installed on the inner side of the front end of the working mechanism. The blade assembly includes a drive box, with a blade disc at the outer end of the drive box. Punch 1, punch 2, punch 3, bending blade 1, bending blade 2, and bending blade 3 are sequentially mounted on the upper end of the blade disc. After bending blade 1 completes the main body angle, two precision bends are achieved through cam stroke control. The first bend results in a small angle at the end, and the second stroke fine-tuning ensures angle consistency, thus improving the stability of the device during production.
[0005] Furthermore, the working mechanism includes a support cabinet, and supports are provided at the four lower corners of the support cabinet. The support cabinet has a working box fixedly installed at the upper middle part, and a docking groove is provided on the inner front side of the working box. By setting up the support cabinet to provide support for the device, the convenience of using the device is improved.
[0006] Furthermore, the drive box is fixedly installed at the inner end of the docking groove, and the drive box is adapted to the docking groove. By setting the drive box to be fixedly installed at the inner end of the docking groove and adapting the drive box to the docking groove, the docking installation of the drive box is more stable, and the stability of the device during use is improved.
[0007] Furthermore, punch one and punch three have the same structure. Punch two is set to complete the outer shape punching and fix the material. At the same time, the small corners at the head and tail are precisely processed. The pressing device ensures the flatness of the material. Punch one and punch three punch the material connection parts to cut off. Differential punching technology is used to avoid burr residue. The punching surface is strictly controlled to face downwards to reduce the generation of burrs in the product and improve product quality.
[0008] Furthermore, the second punch is located below the first and third punches, and the cross-section of the second punch is rectangular.
[0009] Furthermore, the bending blade one, bending blade two, and bending blade three are coaxially connected.
[0010] Furthermore, the T-angle dimensions of the bending blades one, two, and three increase sequentially. Furthermore, the working box and the drive box are internally interconnected.
[0011] In summary, this utility model has the following beneficial effects: 1. The cam stroke control enables two precision bends. The first bend results in a small angle at the end, and the second stroke fine adjustment ensures angle consistency, improving the stability of the equipment during production. The support cabinet provides support for the equipment, improving the convenience of use. 2. By setting the drive box to be fixedly installed at the inner end of the docking groove, the drive box is adapted to the docking groove, making the docking installation of the drive box more stable and improving the stability of the device during use. The shape is punched and the material is fixed by setting the second punch. At the same time, the small corners at the head and tail are precisely processed, and the flatness of the material is ensured by the pressing device. The first punch and the third punch cut off the material connection part. Differential punching technology is used to avoid burr residue. The punching surface is strictly controlled to face downwards to reduce the generation of burrs in the product and improve product quality. Attached Figure Description

[0016] Referring to Figures 1-4, a high-precision spring sheet forming device for automotive radar is shown in a preferred embodiment of the present invention, which includes a working mechanism 1, and a blade assembly mechanism 2 is fixedly installed on the inner side of the front end of the working mechanism 1. The tool assembly mechanism 2 includes a drive box 201. A tool disc 202 is provided at the outer end of the drive box 201. Punch 1 203, punch 204, punch 3 205, bending knife 1 206, bending knife 207, and bending knife 3 208 are sequentially installed on the upper end of the tool disc 202. After the main body is bent by setting bending knife 1 206, punch 2 204 is located below punch 1 203 and punch 3 205. The cross-section of punch 2 204 is rectangular. Bending knife 1 206, bending knife 207, and bending knife 3 208 are coaxially connected. The T-angle dimensions of bending knife 1 206, bending knife 207, and bending knife 3 208 increase sequentially. Two precision bends are achieved by controlling the cam stroke. The small angle is achieved in the later part of the first bend, and the fine adjustment in the second stroke ensures the consistency of the angle, which improves the stability of the device during production.
[0017] Referring to Figures 1-2, the working mechanism 1 includes a support cabinet 101. Support legs 102 are provided at the four corners of the lower end of the support cabinet 101. A work box 103 is fixedly installed in the middle of the upper end of the support cabinet 101. The front inner side is provided with a docking groove 104, and the interior of the working box 103 and the drive box 201 are interconnected. The support cabinet 101 is provided to support the device, which improves the convenience of using the device.
[0018] Referring to Figures 2-4, the drive box 201 is fixedly installed at the inner end of the docking groove 104. The drive box 201 is adapted to the docking groove 104. By setting the drive box 201 to be fixedly installed at the inner end of the docking groove 104, the drive box 201 is adapted to the docking groove 104, making the docking installation of the drive box 201 more stable and improving the stability of the device during use.
[0019] Referring to Figures 3-4, punch 203 and punch 205 have the same structure. The punches are configured differently. Step 204 completes the outer shape punching and fixes the material. Simultaneously, the head and tail corners are precisely machined, and the material flatness is ensured by the pressure device. Punch 1 203 and punch 3 205 cut off the material connection parts. Differential punching technology is used to avoid burr residue. The punching surface is strictly controlled to face downwards to reduce the generation of burrs in the product and improve product quality.
[0020] Specific implementation process: This device achieves high-precision spring sheet forming by relying on the coordinated action of different functional components in the cutter group mechanism 2 according to the logic of fixed punching, bending and cutting. The raw material of the spring sheet to be processed is transported to the processing area below the cutter head 202 to complete the initial positioning and prepare for the subsequent forming process. The drive box 201 drives the cutter head 202 to operate. The punch 204 on the cutter head 202 has a rectangular cross-section and first acts on the raw material to complete the shape punching according to the preset shape of the spring sheet, initially determining the outline of the spring sheet and simultaneously fixing the raw material. After completing the shape punching and the processing of the small corners at the head and tail, the cutter head 202 drives the coaxially connected bending cutter 1 206, bending cutter 207, and bending cutter 3 208 to act in sequence. The cam stroke control achieves two precision bending. In the first bending, bending cutter 1 206 first acts on the raw material to complete the initial bending of the main body angle of the spring sheet and processes the small corner of the rear section of the spring sheet. In the second fine adjustment, the bending cam continues to control the stroke of bending cutter 207 and bending cutter 3 208. The angle dimensions are successively larger than those of the bending blade 206. Further fine-tuning is performed on the bending part of the spring sheet to strictly ensure the consistency of the overall bending angle of the spring sheet. After the bending process is completed, the cutter head 202 drives the punches 203 and 205 with the same structure to complete the punching and cutting. The formed automotive radar spring sheet is separated from the raw material matrix by the separation device. The formed spring sheet is transported to the designated collection area to complete the single spring sheet forming process. Then the device is reset and enters the next processing cycle.
