Description

Technical Field

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

[0002] Brake pad assembly is a crucial component of a vehicle's braking system. It consists of multiple parts, among which the damping pad and friction pad are two key components. The main function of the damping pad is to reduce or eliminate noise generated during braking. During braking, the friction between the brake pads and the brake disc produces vibrations at different frequencies, thus generating noise. The damping pad absorbs and blocks these vibrations, reducing noise transmission and improving driving comfort and quietness. The damping pad and friction pad play unique and irreplaceable roles in the brake pad assembly; their coordinated work not only ensures the high efficiency of the braking system but also significantly improves driving safety and comfort. With the continuous advancement of automotive technology, the performance requirements for brake pad assemblies are constantly increasing. In the future, the materials, structures, and manufacturing processes of damping pads and friction pads will continue to innovate to meet higher standards of driving safety and comfort.

[0003] Traditional sound-absorbing sheet bending often uses large bending equipment, which is bulky and complex in structure. This not only results in high procurement costs but also occupies a lot of production space, placing a heavy economic burden on small enterprises or workshops and limiting their space.

[0019] 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.

[0020] Please see Figure 1-5This utility model provides a technical solution for a manual simple bending machine for sound-absorbing sheets: a manual simple bending machine for sound-absorbing sheets includes a base plate 1, both ends of the base plate 1 are provided with movable grooves, and a bending handle 2 is rotatably connected in each of the two movable grooves. The two sets of bending handles 2 are symmetrically installed, and a quick clamp seat 3 is installed at the top of the base plate 1 between the two sets of bending handles 2. A manual clamping device 4 is installed on the quick clamp seat 3.

[0021] In this embodiment, bending handles 2 are provided at both ends of the base plate 1 to facilitate bending of the bending portions at both ends of the sound-absorbing sheet 6. A quick clamp seat 3 is provided, and a manual clamping device 4 is installed on the quick clamp seat 3. The manual clamping device 4 quickly presses the sound-absorbing sheet 6 and the friction plate 7 onto the base plate 1. The manual clamping device 4 is a common clamping fixture, which is well known in the technical field, and its structure will not be described in detail here.

[0022] Furthermore, a steel pad 5 is provided at the top center of the base plate 1.

[0023] In this embodiment, a steel pad 5 is fixedly installed in the middle of the base plate 1 to protect the sound-absorbing sheet 6, prevent the sound-absorbing sheet 6 from being worn during bending, and reduce the product defect rate.

[0024] Typically, a sound-absorbing plate 6 is provided on the steel pad 5, with bent portions at both ends of the sound-absorbing plate 6, and a friction plate 7 is provided on the sound-absorbing plate 6.

[0025] In this embodiment, by placing the silencing sheet 6 to be bent on the steel pad 5, and placing the friction plate 7 on the silencing sheet 6, it is convenient to press the bent portions of the silencing sheet 6 at both ends of the friction plate 7 together with the device.

[0026] Specifically, pressure grooves are provided on opposite sides of the two sets of bending handles 2, and the pressure grooves are adapted to the bent parts at both ends of the sound-absorbing plate 6.

[0027] In this embodiment, a pressure groove is provided at the bottom of the bending handle 2, wherein the pressure groove is adapted to the bending portions at both ends of the sound-absorbing plate 6, so that the bending portions of the sound-absorbing plate 6 can be bent and pressed onto the friction plate 7 by rotating the two bending handles 2, thereby realizing the press-fitting of the friction plate assembly.

[0028] In addition, two sets of side stops 8 are fixedly connected to both sides of the base plate 1 on the bending handle 2, and a top stop 9 is installed at the end of the base plate 1 away from the manual clamping device 4.

[0029] In this embodiment, side stops 8 and top stops 9 are respectively provided on the base plate 1, wherein the side stops 8 and top stops 9 surround the sound-absorbing plate 6 and the friction plate 7, as shown in the attached figure. Figure 3As shown, the side stops 8 and top baffle 9 on both sides can be used to limit the position of the noise-reducing plate 6 and the friction plate 7, which facilitates the quick assembly of the noise-reducing plate 6 and the friction plate 7 on the bending machine. It also facilitates the accurate alignment of the noise-reducing plate 6 and the friction plate 7, which greatly improves the bending effect and efficiency.

[0030] It should be noted that several sets of mounting holes 10 are provided around the base plate 1.

[0031] In this embodiment, by providing mounting holes 10 around the base plate 1, the device can be easily mounted on the workbench through the mounting holes 10, ensuring the stability of the device during the bending process.

[0032] The working principle and usage process of this utility model are as follows: After the utility model is installed, it is mounted on the workbench at the designated work location through the mounting hole 10. The sound-absorbing sheet 6 to be bent is placed on the steel pad 5, and the friction plate 7 is placed on the sound-absorbing sheet 6. The side blocks 8 on both sides and the top baffle 9 limit the sound-absorbing sheet 6 and the friction plate 7. Then, the manual clamping device 4 is used to press the sound-absorbing sheet 6 and the friction plate 7 onto the steel pad 5. The operator holds the two bending handles 2 and rotates them inward to bend the two ends of the sound-absorbing sheet 6 and press them onto the friction plate 7. After bending is completed, the bending handles 2 are reset and the manual clamping device 4 is released. The sound-absorbing sheet 6 and the friction plate 7 are then removed. The above completes the usage process of a simple manual bending machine for sound-absorbing sheets.

[0033] 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.
