Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and in particular to a metal cutting device for processing automotive brake pads. Background Art

[0002] The raw materials of brake pads are usually supplied in the form of large coils or sheets. In order to process these raw materials into brake pads, it is first necessary to cut them according to the designed dimensions and shapes of the brake pads. Cut the large sheet of friction material into the size and shape suitable for the brake pads of a specific vehicle model;

[0003] In the prior art, a Chinese patent with the publication number "CN111496307A" discloses a sheet cutting device for processing metal products, which relates to the technical field of metal product processing. It includes a support frame, on which a support plate is horizontally fixed. A push plate vertically penetrates through a strip-shaped through hole. One end of the push plate is fixedly connected to a clamping mechanism, and the other end of the push plate is fixed on a conveyor belt. A stepping mechanism for driving a runner stepping mechanism is provided on the support frame, a cutting mechanism for cutting a metal plate is provided on the support frame, and a lifting mechanism for driving the cutting mechanism to move vertically is provided on the support; The present invention cuts the metal plate through the provided cutting mechanism. The provided stepping mechanism can drive the clamping mechanism to drive the metal plate to perform horizontal equidistant stepping movement, and the lifting mechanism drives the blade in the cutting mechanism to reciprocate vertically up and down;

[0004] The above patent can achieve the effect of automatically cutting the metal plate at equal intervals. However, in actual operation, a semi-gear is used to control the cutting interval, and its cutting interval cannot be easily adjusted. It is necessary to replace semi-gears with different diameters for adaptation. This operation is relatively cumbersome and will consume more time. Especially when facing production tasks with different size specifications and different cutting interval requirements, frequently replacing semi-gears will reduce production efficiency and increase the labor cost and time cost of equipment adjustment, which is not conducive to quickly responding to diverse production and processing requirements. For this reason, we propose a metal cutting device for processing automotive brake pads to solve the above problems. Summary of the Invention

[0008] Preferably, the two guide seats are symmetrically distributed along the axis of the moving table. The guide seats are slidably connected to the inner wall of the guide groove. One end of the return spring is fixedly connected to the bottom of the inner cavity of the installation groove, and the other end of the return spring is fixedly connected to the top of the inner cavity of the installation groove.

[0017] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0018] In the present invention, the fixed frame serves as the load-bearing main body, and a cutting machine is built therein. The moving table at the top of the cutting machine is slidably connected to the inner wall of the fixed frame. The guiding seats symmetrically distributed on both sides of the moving table fit with the guiding grooves on the inner wall of the fixed frame, enabling it to always shuttle along the established track.

[0019] The control component controls the cutting accuracy. The rotating roller is the core component, and multiple rows of teeth are designed on its surface. These teeth not only have different quantities, but also cannot form a complete tooth ring when any row is distributed along the circumferential direction. They are evenly arranged from small to large along the length direction of the rotating roller and are tightly meshed with the toothed plate on the top of the moving table. When the rotating roller rotates at a fixed speed, the meshing time of different rows of teeth with the toothed plate is different, thereby ingeniously changing the downward movement time of the cutting machine, and the cutting spacing can be easily adjusted to accurately adapt to the processing requirements of brake pad metals of different sizes.

[0020] The limit seat is assembled with the limit groove on the inner ring wall of the connecting ring, and is connected to the positioning sleeve through components such as a rotating bearing, a fixing ring, and a connecting rod. The positioning spring in the positioning sleeve drives the driving roller to contact the toothed plate. One driving roller is linked with the control motor through a threaded roller. When the control motor rotates, it drives the threaded roller, which in turn drives the driving roller and the rotating roller to move horizontally to select the appropriate tooth position. The other driving roller relies on the telescopic spring in the assembly cylinder and cooperates with the threaded roller to ensure the horizontal movement process. The driving motor at the end of the assembly cylinder continuously outputs power to drive the entire device to operate efficiently, continuously injecting energy into the metal cutting operation of automotive brake pads, fully demonstrating the advantages of the reasonable structure, convenient operation, and high precision of the device.

Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0034] Please refer to Figures 1-9, the present invention provides a metal cutting device for processing automotive brake pads, including a fixed frame 1. Inside the fixed frame 1 is a cutting machine 2. On the top of the cutting machine 2 is installed a moving table 201, which is slidably connected to the inner wall of the fixed frame 1. On the top of the moving table 201 is provided a control component 3. On both sides of the moving table 201 are fixedly connected guiding seats 202, and the two guiding seats 202 are symmetrically distributed along the axis of the moving table 201. On both sides of the inner wall of the fixed frame 1 are opened guiding grooves 203, and the guiding seats 202 are slidably connected to the groove walls of the guiding grooves 203.

On the top of the moving table 201 is fixedly connected a toothed plate 206. On one side of the fixed frame 1 close to the toothed plate 206 is opened a communication window 207. In the fixed frame 1 of the metal cutting device for processing automotive brake pads is provided a cutting machine 2, and the moving table 201 on the top of the cutting machine 2 is slidably connected to the inner wall of the fixed frame 1. The guiding seats 202 on both sides of the moving table 201 are symmetrically distributed along its axis, and the guiding seats 202 are slidably connected to the groove walls of the guiding grooves 203 opened on both sides of the inner wall of the fixed frame 1, which can ensure that the moving table 201 moves smoothly along the established direction during the up and down movement. When the moving table 201 moves downward under the action of an external force, the return spring 205 in the installation groove 204 at the top of one end of the guiding seat 202, with one end fixedly connected to the bottom of the inner cavity of the installation groove 204 and the other end fixedly connected to the top of the inner cavity, relying on the elastic action of the return spring 205, can make the moving table 201 return to the initial position after the rotating roller 301 disengages from the toothed plate 206, realizing the homing operation of the moving table 201.

When any row of teeth 302 is distributed along the circumferential direction of the rotating roller 301, it cannot form a complete toothed ring structure by surrounding one week. The numbers of the multiple rows of teeth 302 are uniformly arranged from small to large along the length direction of the rotating roller 301. The rotating roller 301 is meshed and connected to the toothed plate 206 through the multiple rows of teeth 302. In the control component 3 is a rotating roller 301, on the surface of which are fixedly connected multiple rows of teeth 302 with different numbers.

The rotating roller 301 is meshed and connected to the toothed plate 206 fixedly connected to the top of the moving table 201 through these teeth 302. When the rotating speed of the rotating roller 301 is constant, due to the different numbers of teeth 302 in different rows, when meshing with the toothed plate 206, the downward movement time of the cutting machine 2 will be changed, and thus the cutting distance can be easily adjusted.

[0036] Furthermore, driving rollers 303 are fixedly connected to both ends of the rotating roller 301. Limiting seats 304 are fixedly connected to both sides of the driving rollers 303. The two limiting seats 304 are symmetrically distributed along the axis of the driving roller 303. A connecting ring 305 is sleeved on the surface of the driving roller 303.

The moving sleeve 311 at one end of the connecting rod 309 slides inside the positioning sleeve 310, and a positioning spring 312 is arranged between the two. The sliding seats 313 on both sides of the moving sleeve 311 are slidably connected to the inner walls of the sliding windows 314 on both sides of the positioning sleeve 310. The function of the positioning spring 312 is to make the driving roller 303 in close contact with the toothed plate 206 to ensure smooth meshing.

[0037] Further, a connecting seat 315 is rotatably connected to one end of a driving roller 303 away from the rotating roller 301. A threaded groove 317 is formed at one end of the connecting seat 315 away from the driving roller 303. A threaded roller 318 is disposed inside the threaded groove 317.

In addition, the assembly cylinder 323 is driven by the driving motor 326 to drive the entire device to operate for cutting work.

[0038] Working principle

[0039] In the actual use process, a cutting machine 2 is built into the fixed frame 1. The moving table 201 at the top of the cutting machine 2 is slidably connected to the inner wall of the fixed frame 1. The guide seats 202 on both sides of the moving table 201 and the guide grooves 203 on both sides of the inner wall of the fixed frame 1 are slidably matched, so as to ensure that the moving table 201 can move smoothly up and down along the established direction. When the moving table 201 moves downward under an external force, the return spring 205 in the mounting groove 204 at the top of one end of the guide seat 202, relying on the structure in which its two ends are respectively fixedly connected to the bottom and top of the inner cavity of the mounting groove 204, can make the moving table 201 return to the initial position after the rotating roller 301 disengages from the toothed plate 206, realizing the homing operation of the moving table 201 and performing spacing cutting.

[0040] On the surface of the rotating roller 301 in the control component 3, there are multiple rows of teeth 302 with different numbers and which cannot form a complete toothed ring structure around the circumference. The numbers of these teeth 302 are arranged evenly along the length direction of the rotating roller 301 from small to large. The rotating roller 301 is meshed and connected to the toothed plate 206 at the top of the moving table 201 through the teeth 302. When the rotation speed of the rotating roller 301 is constant, due to the difference in the numbers of teeth 302 in different rows, the downward movement time of the cutting machine 2 will be changed when meshing with the toothed plate 206, thereby realizing the easy adjustment of the cutting spacing.

[0041] Both ends of the rotating roller 301 are fixedly connected with driving rollers 303. The limiting seats 304 on the driving rollers 303 are in contact with the limiting grooves 306 on the inner ring wall of the connecting ring 305. The connecting ring 305 is connected to the fixed ring 308 through a rotating bearing 307. The fixed ring 308 is connected to the positioning sleeve 310 through a connecting rod 309. The moving sleeve 311 at one end of the connecting rod 309 slides in the positioning sleeve 310, and the positioning spring 312 between the two makes the driving roller 303 and the toothed plate 206 in close contact to ensure smooth meshing.

[0042] At one end of a driving roller 303 away from the rotating roller 301, it is threadedly connected to a threaded roller 318 through a connecting seat 315. The threaded roller 318 drives a driven gear 319. The driven gear 319 meshes with a driving gear 320 (the diameter ratio of the driving gear 320 to the driven gear 319 is 1:4). The driving gear 320 is driven by a control motor 321. When the control motor 321 rotates, it drives the driving gear 320, the driven gear 319, and the threaded roller 318 to rotate, thereby driving the driving roller 303 and the rotating roller 301 to move horizontally. In this way, the positions of teeth 302 with different numbers can be selected to mesh with the toothed plate 206, changing the cutting spacing. At the same time, there is a telescopic spring 325 in the fitting cylinder 323 sleeved at one end of the other driving roller 303. One end of it is in contact with the fitting seat 324 of the driving roller 303, and the other end is in contact with the bottom of the inner cavity of the fitting cylinder 323. The telescopic spring 325 cooperates with the threaded roller 318 to ensure the stability of the horizontal movement process of the driving roller 303 and the rotating roller 301.

[0043] One end of the assembly cylinder 323 away from the driving roller 303 is provided with a driving motor 326. The output end of the driving motor 326 is fixedly connected to the assembly cylinder 323. The driving motor 326 provides driving force for the operation of the whole device, ensuring the normal development of the cutting work, so that the device can cut the metal for automotive brake pads according to the set cutting spacing and other requirements.

[0044] The moving table 201 realizes smooth up and down movement and return by the cooperation of the guide seat 202 and the guide groove 203 and the return spring 205; the positioning spring 312 ensures close contact and smooth meshing between the driving roller 303 and the toothed plate 206, and the telescopic spring 325 cooperates with the threaded roller 318 to ensure the stability of the lateral movement during the lateral movement. As a whole, the movement of each component of the device is stable during the working process, ensuring the quality and accuracy of the cutting work. The connection between the components of the device is tight and the cooperation is orderly. From the guiding of the moving table 201 and the adjustment of the cutting spacing by the control component 3 to the stability and driving structure related to the driving roller 303, each part cooperates with each other, reflecting a relatively reasonable structural design, which is beneficial to improving the reliability and service life of the device, and is also convenient for operation and maintenance. By the cooperation of the multi-row different numbers of teeth 302 of the rotating roller 301 in the control component 3 and the toothed plate 206, and the way of driving the rotating roller to move laterally to select different positions of the teeth 302 to mesh by using the control motor 321 and the threaded roller 318, the cutting spacing can be easily and flexibly adjusted to meet the needs of cutting metal for brake pads of different sizes, improving the applicability of the device.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
