AI Technical Summary
During the manufacturing process of automobile accessories, the stamping machine is prone to impact the bolts when it frequently raises and drops metal materials, resulting in damage and deformation of the external threads, making it difficult to disassemble and assemble later.
An automobile accessories stamping machine with an external thread protection mechanism was designed, and it adopts structures such as protective pipes, sliding pipes, movable top covers and flexible collision avoidance layers. The threads are initially protected by the protection pipes. The flexible collision avoidance layer absorbs external impacts to prevent thread damage, and automatically adapts to bolt installations of different lengths by tightening bolts and sliding strips.
It effectively prevents the destruction and deformation of the threads during handling, ensures the stable installation and safety of the bolts during use, and simplifies the later disassembly and assembly process.

Description
Technical Field
[0001] The utility model relates to the technical field of automobile manufacturing, and particularly relates to a stamping machine for automobile parts with an external thread protection mechanism. Background Art
[0002] As an important part of modern industry, the automobile parts manufacturing industry provides high-quality and high-performance components to support the continuous development of automobile production.
[0003] With the continuous progress of automobile technology and the gradually increasing expectations of consumers for safety, fuel efficiency, and environmental protection performance, automobile manufacturers' requirements for the quality and precision of parts are also increasing day by day.
[0004] As one of the core equipment in automobile parts manufacturing, the stamping machine mainly works by using a hydraulic press and a precision-designed die to quickly and accurately stamp a cut and processed metal plate or coil into the required shape.
[0005] However, in actual use, due to the need to frequently load and unload metal materials, the bolts are easily impacted during the handling process, damaging and deforming the external threads on the bolt surface, making the later disassembly and assembly difficult. Content of the Utility Model
[0006] The purpose of the utility model is to provide a stamping machine for automobile parts with a reasonable design and an external thread protection mechanism to solve the above-mentioned defects in view of the defects and deficiencies of the prior art.
[0007] To achieve the above purpose, the utility model adopts the following technical solutions: It includes a stamping machine body, and a plurality of components are installed on the stamping machine body through mounting nuts and mounting bolts. A thread protection structure is provided above the mounting nut on each mounting bolt.
[0008] Preferably, the thread protection structure includes a protection tube provided on the mounting bolt, a sliding tube is slidably installed above the protection tube, and the top end of the sliding tube is connected with a movable top cover through a connecting bearing.
[0009] Preferably, internal threads matching the mounting bolts are provided in both the movable top cover and the protection tube.
[0010] Preferably, several sliding strips are vertically provided on the outer side of the protection tube, several sliding grooves corresponding to the sliding strips are opened in the sliding tube, and several sliding strips are slidably installed in the sliding grooves.
[0011] Preferably, a tightening bolt is provided at the bottom of the protection tube.
[0012] Preferably, a flexible anti-collision layer is provided on the outer side of the sliding tube.
[0013] After adopting the above structure, the beneficial effects of the present utility model are as follows:
[0014] The device initially protects the thread through a protective tube, and then the flexible anti-collision layer on the sliding tube can absorb external impacts, thereby preventing damage to the thread.
[0015] The device can tighten the installation nut while fixing the device by tightening the bolt, preventing loosening.
[0016] The device enables the sliding tube to slide up and down through a sliding bar, so as to automatically adapt to the installation of bolts of different lengths, and thus install bolts at different positions of the punching machine.
[0017] The device can connect the movable top cover to the bolt by rotation through the movable top cover and the connecting bearing, thereby fixing the position of the sliding tube and preventing vibration during use. Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] Refer to Figure 1 - Figure 2As shown, it includes a stamping machine body 1, and multiple components are installed on the stamping machine body 1 through mounting nuts 2 and mounting bolts 3. A thread protection structure is provided above the mounting nut 2 on each mounting bolt 3.
[0026] Refer to Figure 1 - Figure 4 As shown, the thread protection structure includes a protection tube 4 provided on the mounting bolt 3. A sliding tube 6 is slidably installed above the protection tube 4. The top end of the sliding tube 6 is connected to a movable top cover 8 through a connecting bearing 7.
[0027] Refer to Figure 1 - Figure 4 As shown, internal threads 9 matching the mounting bolts 3 are provided in both the movable top cover 8 and the protection tube 4;
[0028] Several sliding bars 10 are vertically provided on the outer side of the protection tube 4. Several sliding grooves 11 corresponding to the sliding bars 10 are opened in the sliding tube 6, and several sliding bars 10 are all slidably installed in the sliding grooves 11; A tightening bolt 5 is provided at the bottom of the protection tube 4;
[0029] A flexible anti-collision layer 12 is provided on the outer side of the sliding tube 6.
[0030] The principle and usage process of the present utility model:
[0031] First, install the stamping machine, and then install the thread protection structure on the components to be installed: Lift the sliding tube 6, and the sliding tube 6 slides upward along the sliding bars 10, so that the movable top cover 8 is away from the protection tube 4. At the same time, align the internal thread 9 of the protection tube 4 with the mounting bolt 3 and screw and tighten it through the tightening bolt 5, thereby pressing the lower mounting nut 2. Then put down the sliding tube 6 and rotate the movable top cover 8 so that the internal thread 9 inside it is connected to the mounting bolt 3. Due to the connecting bearing 7, the rotation of the movable top cover 8 will not affect the protection tube 4. During use, the flexible anti-collision layer 12 can absorb the external impact and keep the internal thread safe. At the same time, when installing on mounting bolts 3 of different lengths, the sliding tube 6 can slide up and down to adapt to the installation.
