Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a brake pad retaining spring processing and bending device. Background Art

[0002] Brake pad retaining springs are important components in the automobile brake system. They are used to ensure the gap between the brake pad and the brake disc and to separate the brake pad after the brake is released to prevent the brake pad from continuously contacting the brake disc. The bending device for processing brake pad retaining springs is a device used to bend and adjust retaining springs during the manufacturing process.

[0003] For example, an automatic bending device for processing brake pad retaining springs disclosed in the authorization announcement number CN208373919U includes a horizontally arranged bottom plate, support plates are welded on both sides of the top of the bottom plate, and a first slide groove is opened along the height direction of the two support plates on the side close to each other, and a first spring is connected to the top inner wall of the first slide groove, and the bottom end of the first spring is connected to a first slider slidably installed inside the first slide groove. After adopting the above technical solution, the beneficial effects of the utility model are: it is convenient to quickly remove the bent retaining spring, saving time and effort, improving the processing efficiency of the device, and suitable for market promotion.

[0004] Although the above patent facilitates the quick removal of the bent retaining spring, saving time and effort, when bending, there is no arc-shaped structure to support one side, and the middle part of the steel plate may fold vertically instead of arc-shaped after bending.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-5 As shown, a technical solution provided by the utility model:

[0026] A brake pad retaining spring processing and bending device comprises a frame 1, a storage platform 2 is arranged in the middle of the bottom end of the frame 1, an arc-shaped convex block 3 is arranged on the upper end surface of the storage platform 2, and an arc-shaped concave block 4 is arranged on the inner top of the frame 1; a bending mechanism is arranged between the top ends of the frame 1, and the bending mechanism comprises a bracket 5, the bracket 5 is fixedly installed just above the top end of the frame 1, a hydraulic rod 6 is fixedly installed in the middle of the top end of the bracket 5, and a pressing platform 7 is fixedly installed on the output shaft of the hydraulic rod 6;

[0027] In this embodiment, when processing the retaining spring, the workpiece is placed on the upper ends of the four push rods 18 for support, and then the hydraulic rod 6 is started. After the hydraulic rod 6 is started, the pressing platform 7 is controlled to be pressed down. When the pressing platform 7 is pressed down, the arc-shaped recessed block 4 is driven to be pressed down synchronously until the two sides of the pressing platform 7 are against the two sides of the plate and then continue to descend. At this time, the arc-shaped protrusion 3 and the arc-shaped recessed block 4 will bend the workpiece into an arc-shaped structure. In this way, when the workpiece is bent, the middle part of the workpiece is positioned by the arc-shaped protrusion 3 and the arc-shaped recessed block 4 and will not be folded vertically, so that the retaining spring can be quickly formed.

[0028] like Figure 2 and Figure 4As shown, a top material ejection mechanism is arranged outside the top of the arc-shaped concave block 4, and the ejection mechanism includes a bottom box 8, which is fixedly installed at the lower middle part of the press platform 7, and a top plate 9 is movably installed at the lower inner part of the bottom box 8, and the top of the top plate 9 is movably connected with the inner part of the bottom box 8 through a plurality of springs 10, and a through groove 11 is provided in the middle of the arc-shaped concave block 4, and the ejection mechanism also includes a slide groove 12, and the slide groove 12 is provided on both sides of the inner wall of the press platform 7, and sliders 13 are arranged outside the four corners of the arc-shaped concave block 4, and the slider 13 is movably connected with the slide groove 12, and a guide rod 14 is fixedly installed at the top of the slider 13, and a guide groove 15 is provided at the upper inner end of the press platform 7 located at the slide groove 12, and the guide rod 14 is movably connected with the guide groove 15, and a spring 16 is provided in the middle of the guide rod 14, and the other end of the spring 16 is provided at the upper inner end of the slide groove 12;

[0029] In this embodiment, when bending, the arc-shaped protrusion 3 and the arc-shaped recessed block 4 will bend the workpiece into an arc-shaped structure, and at the same time press the top plate 9 into the bottom box 8 and compress the spring 2 10. When the retaining spring is formed, the pressure plate 7 is controlled to be lifted. At this time, the compressed spring 2 10 will rebound to control the top plate 9 to descend, and the retaining spring inside the arc-shaped recessed block 4 will pop out. In this way, after the retaining spring is bent, the retaining spring can be automatically popped out, thereby achieving the purpose of facilitating material unloading.

[0030] like Figure 3 and Figure 5 As shown, the four corners of the arc-shaped protrusion 3 are provided with a supporting mechanism, which includes a rod groove 17, which is opened at the four corners of the arc-shaped protrusion 3, and the insides of the four rod grooves 17 are all movably sleeved with a push rod 18, and a spring 19 is provided between the push rod 18 and the lower outer part of the arc-shaped protrusion 3;

[0031] In this embodiment, the device has rod grooves 17 at the four corners of the arc-shaped protrusion 3, and push rods 18 are movably installed inside the four rod grooves 17. The rod grooves 17 are movably connected to the lower end surface of the arc-shaped protrusion 3 through spring three 19. In this way, when placing the workpiece, the workpiece can be lifted and supported by the four push rods 18, and in the process of pressing and bending, the four push rods 18 will drop synchronously without causing movement interference, thereby achieving the purpose of facilitating loading.

[0032] Working principle: When processing the retaining ring, place the workpiece on the upper ends of the four push rods 18 for support, and then start the hydraulic rod 6. After the hydraulic rod 6 is started, the pressing platform 7 is controlled to be pressed down. When the pressing platform 7 is pressed down, the arc-shaped recessed block 4 is driven to be pressed down synchronously until the two sides of the pressing platform 7 are against the two sides of the plate and then continue to decline. At this time, the arc-shaped protrusion 3 and the arc-shaped recessed block 4 will bend the workpiece into an arc-shaped structure, and at the same time press the top plate 9 into the bottom box 8 and compress the spring 2 10. When the retaining ring is formed, the pressing platform 7 is controlled to lift. At this time, the compressed spring 2 10 will rebound to control the top plate 9 to descend, and the retaining ring inside the arc-shaped recessed block 4 will pop out.
