Description

Technical Field

[0001] This utility model relates to the field of automotive muffler hook technology, specifically to a cold pressing forming machine for automotive muffler hooks. Background Technology

[0002] A car muffler is mainly used to reduce the noise generated by the engine of a motor vehicle. Its principle is that the car exhaust pipe consists of two pipes of different lengths. These two pipes are separated and then converge. Since the length difference between the two pipes is equal to half the wavelength of the sound wave emitted by the car, the two sound waves interfere and cancel each other out when they overlap, thus reducing the sound intensity and decreasing the transmitted sound, thereby achieving a muffler effect. With the development of the modern automotive industry and industry requirements, existing cars must be equipped with car mufflers. When using a car muffler, a hook needs to be installed on its side surface.

[0003] Chinese utility model patent application number 202220745472.X discloses a cold pressing forming device for automotive muffler hooks. The above technical solution can realize the quick assembly and disassembly of the forming mold through a lifting installation mechanism, thereby facilitating the replacement of the forming mold and effectively improving the replacement efficiency of the forming mold. This allows the forming device to quickly change the forming mold according to the processing requirements of the hook, greatly improving the practicality of the forming device and helping to achieve efficient production of automotive muffler hooks of different specifications.

[0004] However, in actual use, when only the lower mold is replaced for hook materials of different diameters, the upper mold may not be able to meet the requirements for compression deformation of the hook material during cold pressing because the reserved position of the upper mold is not suitable for the hook material of that diameter and length. This results in a significant waste of raw materials and an increase in processing costs. The above technical solution requires bolt fixing when replacing the upper mold, which is troublesome to install and disassemble, thereby reducing the production efficiency of hooks and making it inconvenient to use.

[0005] Therefore, a cold pressing forming machine for automotive muffler hooks is proposed. Utility Model Content

[0025] like Figure 1-4 As shown, a cold pressing forming machine for automotive muffler hooks includes a processing base plate 1. A trapezoidal groove 101 is formed on the top of the processing base plate 1. A cold pressing frame 2 is mounted on the top of the processing base plate 1. A hydraulic telescopic rod 3 is mounted on the cold pressing frame 2. An upper mold 4 is housed inside the cold pressing frame 2. An installation groove 401 is formed on the top of the upper mold 4. An upper mold fixing component 5 is mounted on the cold pressing frame 2 to install and fix the upper mold 4. The upper mold fixing component 5 includes a housing 50 disposed at the bottom end of the hydraulic telescopic rod 3. 1. A lower mold 6 is provided at the top of the processing base plate 1, and a lower mold fixing component 7 is provided on the processing base plate 1 to install and fix the lower mold 6. Specifically, the upper mold 4 and the lower mold 6 can be replaced by the upper mold fixing component 5 and the lower mold fixing component 7, respectively. For hook parts of different diameters, the upper mold 4 and the lower mold 6 can be replaced with appropriate ones. During cold pressing, it can fit more closely with the car muffler hook, avoid its displacement during cold pressing, and thus ensure the cold pressing effect and quality.

[0026] like Figure 2 and 4 As shown, an electric telescopic rod 502 is provided at the top of the interior of the housing 501. The telescopic end of the electric telescopic rod 502 is connected to a compression trapezoidal block 503. A connecting groove 5031 is provided on each side of the inclined surface of the compression trapezoidal block 503. Specifically, the extension and retraction of the electric telescopic rod 502 can drive the compression trapezoidal block 503 to rise and fall.

[0027] like Figure 4 As shown, two sliding trapezoidal blocks 504 are slidably arranged inside the housing 501. Each of the inclined surfaces of the sliding trapezoidal blocks 504 is provided with a slider 505 that is slidably arranged inside the connecting groove 5031. Specifically, when the extrusion trapezoidal block 503 is raised or lowered, since the slider 505 is slidably arranged inside the connecting groove 5031, it can drive the two sliding trapezoidal blocks 504 to move closer or further away from each other, and thus also drive the two L-shaped mounting plates 506 to move closer or further away from each other. When installing the upper mold 4, the L-shaped mounting plates 506 can be inserted into the mounting groove 401. Then, the electric telescopic rod 502 extends and can push the extrusion trapezoidal block 503 to move downward. Therefore, the extrusion trapezoidal block 503 can extrude the sliding trapezoidal blocks 504 on both sides, thereby causing the two L-shaped mounting plates 506 to move away from each other and then be inserted into the mounting groove 401 to realize the installation of the upper mold 4.

[0028] like Figure 2 and 4 As shown, each of the two sliding trapezoidal blocks 504 has a symmetrical L-shaped mounting plate 506 at its bottom.

[0029] like Figure 3 As shown, a through groove 601 is provided on the lower mold 6, and a trapezoidal slider 701 adapted to the trapezoidal groove 101 is provided at the bottom end of the lower mold 6; specifically, the trapezoidal groove 101 can limit the lower mold 6, so that it can only slide along the direction of the trapezoidal groove 101.

[0030] like Figure 3 As shown, the lower mold fixing component 7 includes two fixing plates 702 set at the top of the processing base plate 1. A limiting rod 703 is movably arranged in the through groove 601. A limiting cap 704 is provided at one end of the limiting rod 703, and a screw rod 705 is provided at the other end of the limiting rod 703. A nut 706 is threaded on the screw rod 705. Specifically, the limiting rod 703 is inserted into the through groove 601, then one side of the limiting cap 704 is attached to one side of the fixing plate 702, and then the nut 706 is tightened, so that one side of the nut 706 is attached to one side of the fixing plate 702, thereby stably fixing the lower mold 6 on the processing base plate 1.

[0031] In summary: Mold 4 and lower mold 6 can be replaced by upper mold fixing component 5 and lower mold fixing component 7 respectively. For hook components of different diameters, the upper mold 4 and lower mold 6 can be replaced with appropriate ones. During cold pressing, this allows them to fit more closely to the car muffler hook, preventing it from shifting during cold pressing, thus ensuring the cold pressing effect and quality.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
