Description

Technical Field

[0001] This utility model belongs to the field of brake disc processing technology, and in particular relates to a stamping die for processing automotive brake discs. Background Technology

[0002] A brake disc is a tool that uses brake calipers to clamp the brake disc and generate braking force on a car.

[0003] It is generally processed using stamping dies during production.

[0004] According to a public disclosure (CN 220028431U), a stamping die for processing automotive brake discs includes a working platform. A lower template for placing the disc is installed on the inner side of the working platform. An upper template, which closes with the lower template, is positioned above it. The upper template is connected to a cylinder installed inside the working platform, enabling its vertical movement. A positioning mechanism distributed on the lower template automatically positions the disc on the upper surface of the lower template. The positioning mechanism includes a positioning unit and a reset unit. The positioning unit is used during the downward pressing of the upper template. This invention, by setting a positioning mechanism, eliminates the need for manual adjustment of the brake disc's position during processing. The brake disc is automatically positioned in the center of the lower template during the downward pressing process of the upper template, further improving work efficiency.

[0005] In the aforementioned application, the mold cannot be pushed out after stamping due to the cooperation between the upper template and the cylinder assembly. It needs to be removed manually. The temperature of the brake disc after stamping is too high, which can easily cause harm to the human body. Therefore, the effect is not ideal. Summary of the Invention

[0006] The purpose of this utility model is to provide a stamping die for processing automotive brake discs. Through the cooperation between components such as the motor, support block, rotating shaft, slide groove, rack, and half gear inside the ejection device, when the motor starts, the rotating shaft rotates, causing the half gear to intermittently mesh with the rack. When meshing, the push rod on the side of the rack ejects the stamped brake disc. The ejected brake disc enters the collection box through the transmission belt, achieving both ejection and collection of the brake disc, thus solving the existing problems.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a stamping die for processing automotive brake discs, including a base plate, a processing table fixedly connected to the top of the base plate, a stamping device provided on the top of the processing table, and an ejection device provided inside the processing table.

[0009] The ejection device includes a motor, which is disposed on the side of the processing table. A support block is fixedly connected to the top of the processing table. The side of the motor is fixedly connected to the side of the support block. A rotating shaft is fixedly connected to the output shaft of the motor. A sliding groove is provided inside the processing table. A rack is slidably connected inside the sliding groove. A half gear is fixedly passed through the circumference of the rotating shaft. A push rod is fixedly connected to the side of the rack.

[0010] Furthermore, the inner wall of the slide is elastically connected with a spring, and the end of the spring away from the slide is fixedly connected to the side of the rack. This design facilitates the rack to be reset by the spring.

[0011] Furthermore, a conveyor frame is fixedly connected to the top of the base plate, and a conveyor belt is drivenly connected to the circumferential surface of the conveyor frame. A collection box is fixedly connected to the top of the base plate. This design facilitates the conveyor belt to transport the ejected brake disc.

[0012] Furthermore, the side of the rack is elastically connected to the inner wall of the slide groove by a spring, and the collection box is located below the conveyor frame. This design facilitates the collection of brake discs through the collection box.

[0013] Furthermore, a heat dissipation device is provided on the top of the base plate. The heat dissipation device includes a fan frame, and a rotating shaft is rotatably connected inside the fan frame. A first belt groove is formed on the circumferential surface of the rotating shaft, and a second belt groove is formed on the circumferential surface of the rotating shaft. A belt is driven to the circumferential surface of the first belt groove, and the inner side of the belt is on the circumferential surface of the second belt groove. Blades are fixedly connected to the circumferential surface of the rotating shaft. This design facilitates the rotation of the rotating shaft through belt transmission, thereby driving the rotating shaft to rotate and allowing the blades to dissipate heat from the brake disc on the conveyor belt.

[0014] Furthermore, a protective sleeve is fixedly connected to the circumferential surface of the rotating shaft, and a ventilation opening is provided on the side of the protective sleeve. This design helps to prevent the blades from causing harm to the human body when passing through the protective sleeve.

[0015] Furthermore, the number of blades is set to six, and they are arranged in a circumferential array on the circumferential surface of the rotation axis. This design is beneficial for heat dissipation through multiple blades.

[0016] This utility model has the following beneficial effects:

[0017] This invention utilizes the interplay between components such as the motor, support block, rotating shaft, slide groove, rack, and half gear within the ejection device. When the motor starts, the rotating shaft rotates, causing the half gear to intermittently mesh with the rack. During meshing, the push rod on the side of the rack ejects the stamped brake disc. The ejected brake disc then enters the collection box via a transmission belt, achieving both ejection and collection of the brake disc.

[0018] This invention achieves a cooling effect by coordinating the components such as the fan frame, rotating shaft, belt, blades, and protective sleeve inside the heat dissipation device. When the motor starts, the rotating shaft, driven by the belt, rotates, causing the blades on the rotating shaft to dissipate heat from the brake disc on the conveyor belt.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The ejection device 4 includes a motor 41, which is mounted on the side of the processing table 2. A support block 42 is fixedly connected to the top of the processing table 2. The side of the motor 41 is fixedly connected to the side of the support block 42. A rotating shaft 43 is fixedly connected to the output shaft of the motor 41. A sliding groove 44 is provided inside the processing table 2. A rack 45 is slidably connected inside the sliding groove 44. A half gear 46 is fixedly passed through the circumference of the rotating shaft 43. A push rod 47 is fixedly connected to the side of the rack 45.

[0030] A spring 48 is elastically connected to the inner wall of the slide groove 44. The end of the spring 48 away from the slide groove 44 is fixedly connected to the side of the rack 45. This design facilitates the reset of the rack 45 through the spring 48.

[0031] A conveyor frame 49 is fixedly connected to the top of the base plate 1. A conveyor belt 410 is connected to the circumference of the conveyor frame 49. A collection box 411 is fixedly connected to the top of the base plate 1. This design is beneficial for the conveyor belt 410 to convey the ejected brake disc.

[0032] The side of the rack 45 is elastically connected to the inner wall of the slide 44 by a spring 48. The collection box 411 is located below the conveyor frame 49. This design facilitates the collection of brake discs through the collection box 411.

[0033] A heat dissipation device 5 is provided on the top of the base plate 1. The heat dissipation device 5 includes a fan frame 51. A rotating shaft 52 is rotatably connected inside the fan frame 51. A first belt groove 53 is formed on the circumferential surface of the rotating shaft 43. A second belt groove 54 is formed on the circumferential surface of the rotating shaft 52. A belt 55 is driven to the circumferential surface of the first belt groove 53. The inner side of the belt 55 is on the circumferential surface of the second belt groove 54. A blade 56 is fixedly connected to the circumferential surface of the rotating shaft 52. This design is conducive to the rotation of the rotating shaft 43 by the transmission of the belt 55, which drives the rotating shaft 52 to rotate, so that the blade 56 can dissipate heat from the brake disc on the conveyor belt 410.

[0034] A protective sleeve 57 is fixedly connected to the circumferential surface of the rotating shaft 52. A ventilation opening 58 is provided on the side of the protective sleeve 57. This design helps to prevent the blade 56 from causing harm to the human body through the protective sleeve 57.

[0035] The number of blades 56 is set to six, and they are arranged in a circumferential array on the circumferential surface of the rotation axis 52. This design is beneficial for heat dissipation through multiple blades 56.

[0036] One specific application of this embodiment is as follows: After the brake disc is stamped, it needs to be ejected. First, the motor 41 is started. When the motor 41 is started, the shaft 43 on the output shaft of the motor 41 rotates counterclockwise. When the shaft 43 rotates counterclockwise, the half gear 46 on the shaft 43 intermittently meshes with the rack 45. When the half gear 46 meshes with the rack 45, the rack 45 slides to the right, causing the push rod 47 to eject the stamped brake disc. When the shaft 43 rotates clockwise, the half gear 46 on the shaft 43 cannot mesh with the rack 45, and ejection is not possible at this time.

[0037] The newly installed brake disc is overheating and needs to be cooled. First, the motor 41 is started. When the motor 41 starts, the shaft 43 on the output shaft of the motor 41 rotates counterclockwise. When the shaft 43 rotates counterclockwise, the shaft 52 driven by the belt 55 rotates counterclockwise. When the shaft 52 rotates counterclockwise, the blades 56 on the shaft 52 cool the brake disc on the conveyor belt 410. The cooled brake disc enters the collection box 411. When the shaft 43 rotates clockwise, the shaft 52 driven by the belt 55 rotates clockwise. When the shaft 52 rotates clockwise, the blades 56 on the shaft 52 cannot cool the brake disc on the conveyor belt 410.
