Description

Technical Field

[0001] This utility model relates to the processing of sound-absorbing sheets, and in particular to an upward bending machine. Background Technology

[0002] Brake pad noise dampers are important components in automotive braking systems used to reduce braking noise. Their main function is to reduce abnormal noise during braking by absorbing vibration and buffering impact. During braking, the friction between the brake pads and the brake disc can generate vibration noise (especially high-frequency whistling). The noise damper absorbs vibration energy through elastic materials (such as rubber, silicone, or composite materials) to suppress noise. During emergency braking or frequent braking, the noise damper can reduce direct collisions between the brake pads and the calipers and brackets, extending the life of components. Some noise dampers are designed as heat insulation layers to protect the brake pad backing from high-temperature damage. The noise damper clips, as standardized carriers, can be adapted to automated production lines (such as robot gripping and conveyor belt transfer) to achieve rapid feeding, transfer, or stacking of noise dampers.

[0003] Traditional sound-absorbing sheet bending fixtures bend downwards, resulting in unstable bending structure and misalignment of the bending mechanism. This leads to inaccurate bending of the sound-absorbing sheets and a low product yield. Utility Model Content

[0004] This utility model provides an upward bending machine, which aims to solve the problem that traditional sound-absorbing sheet bending fixtures, by bending downwards, have unstable bending structures, causing the bending mechanism to deviate, resulting in inaccurate bending of the sound-absorbing sheets and low product yield.

[0005] This utility model is implemented as follows: an upward bending machine includes a work plate, a lower pressure block is installed above the work plate, and a bending mechanism is symmetrically installed on both the left and right ends of the lower pressure block; the bending mechanism includes a bending seat, which is installed on one side of the work plate, and a bending bearing is symmetrically arranged at both ends of the top of the bending seat. Bending arms are sleeved on the two sets of bending bearings, and the bending arms are rotatably connected to the bending seat through the bending bearings at both ends. A bending block is fixedly connected to the side wall of the bending bearing near the lower pressure block.

[0006] Preferably, a mounting plate is fixedly connected to the top of the pressing block, and a clamp handle is fixedly connected to the top of the mounting plate.

[0007] The beneficial effect of adopting the above-mentioned further solution is that it can press the sound-absorbing sheet tightly, which makes it easier to bend both ends of the sound-absorbing sheet through the bending mechanism on both sides.

[0008] Preferably, limit blocks are symmetrically installed at both ends of the mounting plate, and each limit block is provided with a limit screw, the position of which corresponds to the top position of the bending bearing.

[0009] The beneficial effects of adopting the above-mentioned further solution are: to limit the contact between the bending mechanisms on both sides and to limit the bending angle.

[0010] Preferably, the mounting plate is equipped with two sets of guide shafts, and the working plate is provided with guide pads directly below the two sets of guide shafts.

[0011] The beneficial effects of adopting the above-mentioned further solution are: ensuring that the lower pressure block moves up and down smoothly, and that the guide pad is compatible with the guide shaft.

[0012] Preferably, the bottom of the pressing block is provided with several sets of spring plungers.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, under the reset action of the spring plunger, the silencing plate is disengaged from the lower pressure block, preventing the silencing plate from sticking to the lower pressure block, which facilitates material unloading.

[0014] Preferably, each of the bending seats has a mounting base fixedly connected to its bottom.

[0015] The advantages of adopting the above-mentioned further solution are: it facilitates fixing to the external mold via the mounting base, while improving the stress on the base.

[0016] Preferably, the working plate has several mounting holes around its perimeter.

[0017] The advantage of adopting the above-mentioned further solution is that it facilitates installation on the external mold through the mounting holes.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an upward bending machine that uses a lower pressure block to press the sound-absorbing sheet on the work plate, and uses bending mechanisms on both sides to bend the sound-absorbing sheet upwards. The size of the bending block is adapted to the size of the sound-absorbing sheet, making it easy to adapt the size of the bending block to the size of the sound-absorbing sheet, facilitating the bending of sound-absorbing sheets of different sizes. This device improves the stability of the structure by improving the force on the bending arm and the base through upward bending of the sound-absorbing sheet, preventing the bending mechanism from shifting, ensuring the bending accuracy of the sound-absorbing sheet, and improving the product yield.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution for an upward bending machine: an upward bending machine includes a working plate 1, a lower pressure block 2 is installed above the working plate 1, and a bending mechanism 3 is symmetrically installed on both the left and right ends of the lower pressure block 2.

[0027] The bending mechanism 3 includes: a bending seat 31, which is installed on one side of the working plate 1. A bending bearing 32 is symmetrically arranged at both ends of the top of the bending seat 31. Bending arms 33 are sleeved on the two sets of bending bearings 32. The bending arms 33 are rotatably connected to the bending seat 31 through the bending bearings 32 at both ends. A bending block 34 is fixedly connected to the side wall of the bending bearing 32 near the lower pressure block 2.

[0028] In this embodiment, the sound-absorbing sheet 11 on the working plate 1 is pressed by the lower pressure block 2, and the two sides of the sound-absorbing sheet 11 are bent upward by the bending mechanism 3 on both sides. The bending mechanism 3 includes a bending seat 31, and bending grooves are opened at both ends of the bending seat 31. Two sets of bending arms 33 are located in the bending grooves at both ends and are rotatably connected to the bending seat 31 by bending bearings 32. The bending arms 33 can rotate in the bending grooves. A bending block 34 is provided on the inner side of the bending arm 33 and is connected to the bending arm 33 by an external bending drive to drive the bending arm 33. The bending arm 33 rotates inward, and the bending block 34 bends the sound-absorbing plate 11 upward. The bending block 34 is detachably connected to the bending arm 33. The size of the bending block 34 is adapted to the size of the sound-absorbing plate 11, which makes it easy to adapt the size of the bending block 34 to the size of the sound-absorbing plate 11. This facilitates the bending processing of sound-absorbing plates 11 of different sizes. By bending the sound-absorbing plate upward, improving the force on the bending arm and the base, this device improves the stability of the structure, prevents the bending mechanism from deviating, ensures the bending accuracy of the sound-absorbing plate, and improves the product yield.

[0029] Furthermore, a mounting plate 4 is fixedly connected to the top of the lower pressure block 2, and a clamp handle 5 is fixedly connected to the top of the mounting plate 4.

[0030] In this embodiment, by providing an installation plate 4, it is convenient to fix the pressure block 2 at the bottom of the installation plate 4. By fixing the clamp handle 5 at the middle position of the top of the installation plate 4, it is convenient to connect the clamp handle 5 to the external pressure cylinder. The external pressure cylinder drives the pressure block 2 to rise and fall, pressing the sound-absorbing sheet 11, which facilitates the bending of both ends of the sound-absorbing sheet 11 by the bending mechanism 3 on both sides.

[0031] Typically, limit blocks 6 are symmetrically installed at both ends of the mounting plate 4, and limit screws 7 are provided on each limit block 6. The position of the limit screws 7 corresponds to the top position of the bending bearing 32.

[0032] In this embodiment, limit blocks 6 are fixedly installed at both ends of the mounting plate 4. The positions of the limit blocks 6 at both ends correspond to the bending mechanisms 3 on both sides. Limit screws 7 are provided on the limit blocks 6 to limit the bending mechanisms 3 on both sides and limit the bending angle.

[0033] Specifically, two sets of guide shafts 8 are installed on the mounting plate 4, and guide pads 9 are correspondingly set on the working plate 1 directly below the two sets of guide shafts 8.

[0034] In this embodiment, guide shafts 8 are symmetrically installed at the front end of the mounting plate 4 to ensure that the lower pressure block 2 moves up and down smoothly, and the guide pad 9 is adapted to the guide shaft 8.

[0035] In addition, several sets of spring plungers 10 are provided around the bottom of the lower pressure block 2.

[0036] In this embodiment, several sets of spring plungers 10 are arranged around the bottom of the lower pressure block 2. When the lower pressure block 2 is pressed onto the silencing plate 11, the spring plungers 10 are compressed and contact the top of the silencing plate 11 by the bottom spring column. When the lower pressure block 2 rises, the silencing plate 11 is disengaged from the lower pressure block 2 by the reset action of the spring plungers 10, preventing the silencing plate 11 from sticking to the lower pressure block 2 and facilitating material unloading. The structure of the spring plungers 10 is a common spring column structure, which is well known to those skilled in the art, and will not be described in detail here.

[0037] In addition, each bending seat 31 has a mounting base 35 fixedly connected to its bottom.

[0038] In this embodiment, by fixing the mounting base 35 to the bottom of the bending base 31, it is convenient to fix it to the external mold by the mounting base 35, while improving the stress on the base.

[0039] It should be noted that several mounting holes are provided around the perimeter of the work plate 1.

[0040] In this embodiment, mounting holes are provided around the perimeter of the work plate 1 to facilitate mounting on the external mold.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
