Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe processing technology, specifically to a shaping fixture for thin-walled exhaust pipe parts. Background Technology

[0002] The exhaust pipe is part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, exhaust pipe and muffler. The three-way catalytic converter, which controls the emission of pollutants from the engine, is also installed in the exhaust system. The exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe.

[0003] When processing and producing exhaust pipes, a stamping device is generally used to stamp thin iron sheets. The iron sheets are squeezed by a molding rod to form the shape of the exhaust pipe. After stamping, the formed exhaust pipe is located between the upper and lower molds, and workers need to remove the exhaust pipe by hand. If the equipment malfunctions or the workers accidentally start the stamping equipment, it will cause injury to the workers' hands. Therefore, we have proposed a forming fixture for thin-walled exhaust pipe parts. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 As shown, a forming fixture for a thin-walled exhaust pipe includes an exhaust pipe fixture body 1 and a lower mold 2 and an upper mold 3 disposed therein. A lower stamping rod is disposed on the right side of the lower mold 2, and an upper stamping rod is disposed on the right side of the upper mold 3. A stamping box 4 is disposed inside the exhaust pipe fixture body 1, and a magnet 10 is disposed inside the stamping box 4. A torsion spring 14 is sleeved on the surface of the rotating shaft of the lower U-shaped block 51, which can release the force applied to the lower U-shaped block 51 after deflection, and can return the lower U-shaped block 51 to the starting position through the elastic force of the torsion spring 14. The position of the upper U-shaped block 52 is fixed by the magnet 10, thereby preventing the position of the molding rod 7 from shifting during stamping. An arc groove 11 is opened inside the stamping box 4, and a groove is opened on the surface of the stamping box 4. The arc groove 11 can ensure the range of motion of the connecting rod when the first universal ball 6 rotates.

[0017] The groove allows the molding rod 7 to be moved and adjusted easily. The stamping box 4 has a deflection structure 5 inside. The deflection structure 5 includes a lower U-shaped block 51 hinged inside the stamping box 4. Arc-shaped pieces 53 are fixedly connected to the front and rear sides of the top of the lower U-shaped block 51. An upper U-shaped block 52 is fixedly connected to the top of the arc-shaped pieces 53. The opposite side of the arc-shaped pieces 53 on the front and rear sides is slidably connected to the second universal ball 8. When the upper U-shaped block 52 deflects, it can drive the second universal ball 8 and the molding rod 7 to move, so as to drive the molding rod 7 to flip and move the molding rod 7 away from the upper mold 3 and the lower mold 2, thereby ensuring the safety of the workers when removing the exhaust pipe. A first universal ball 6 is embedded inside the stamping box 4. The right side of the first universal ball 6 is fixed to the second universal ball 8 through a connecting rod. The right side of the second universal ball 8 is fixedly connected to the molding rod 7.

[0018] The bottom of the upper stamping rod is fixedly connected to a second locking block 13, and the top of the lower stamping rod is fixedly connected to a first locking block 12. The first locking block 12 and the second locking block 13 are horizontally aligned. By setting the first locking block 12 and the second locking block 13, when the molding rod 7 is pressed down, the position of the molding rod 7 will not shift, thereby ensuring the stability of the operation of the molding rod 7.

[0019] A handle 9 is fixedly connected to the top of the upper U-shaped block 52. The surface of the handle 9 is provided with anti-slip ridges, which makes it easy for the staff to pull the upper U-shaped block 52. The anti-slip ridges can increase the friction of the staff's hands.

[0020] Several limiting rods 15 are provided on the left and right sides of the top of the lower mold 2. The limiting rods 15 are located at the rear corner of the lower mold 2. The setting of the limiting rods 15 can facilitate the quick positioning of the iron sheet when it is placed on the top of the lower mold 2, thereby improving the stability of the stamping operation.

[0021] It is worth noting that the exhaust pipe tool body 1 is formed by placing an iron sheet on top of the lower mold 2 and extruding it through the molding rod 7 and the upper mold 3, causing the iron sheet to deform and wrap around the surface of the molding rod 7, thereby forming an exhaust pipe. Since the exhaust pipe tool body 1 is existing technology, it will not be described in this solution.

[0022] When the molding rod 7 returns to the starting position, it is located above the lower stamping rod. When the upper mold 3 descends to stamp the molding rod 7, it will drive the upper stamping rod to descend together and press the molding rod 7. Since the upper stamping rod and the lower stamping rod are existing technologies, they will not be described in this solution.

[0023] Working principle: After the worker places the thin iron sheet used to make the exhaust pipe on the top of the lower mold 2, the exhaust pipe fixture body 1 can be activated, causing the thin iron sheet to wrap around the surface of the molding rod 7 and form it. Then, the lower mold 2 is raised and the wrapping of the molding rod 7 is released. Then, the handle 9 can be pulled downwards. As the handle 9 moves, the upper U-shaped block 52 is offset downwards, and the arc-shaped piece 53 and the lower U-shaped block 51 are offset. At the same time, the angle of the first universal ball 6 is offset, and simultaneously, the second universal ball 8 moves the connecting rod away from the angle of the exhaust pipe. One end of the molding rod 7 provides support. When the molding rod 7, the first universal ball, and the connecting rod are moved under force, they can deflect. Thus, when the second universal ball 8 moves, it can drive the molding rod 7 to shift. At this time, the molding rod 7 can be separated from the upper mold 3 and the lower mold 2. Then, the worker can remove the die-cast exhaust pipe. After that, the handle 9 can be released. The elastic force of the torsion spring 14 can drive the lower U-shaped block 51 back to the starting position, thereby driving the molding rod 7 back to the starting position. The above operation can be repeated to achieve continuous operation.
