[0002] Punching stainless steel round pipes is a common pipe fitting processing technology. When punching pipe fittings, a punching machine is usually used. The operator fixes the pipe fitting on the positioning die of the punching machine and punches out the hole shape downward through the punch.

[0003] For small-scale workshops, the current workshops use semi-automatic punching machines, which require manual intervention. When punching a circle of ventilation holes from the outside to the inside of the stainless steel round pipe opening, the operator needs to rotate the pipe body to the punching position for processing in turn, and generally holds the pipe body by hand to stabilize it during the punching process. This punching method is time-consuming and laborious, and has low efficiency.

[0004] Therefore, aiming at the semi-automatic punching machine used in the factory, we further improve it. Under the condition of controlling the cost, a punching fixture for stainless steel pipes is provided. By installing the pipe fitting through the clamping structure and rotating it for punching, the punching efficiency is improved, and the workload of operators can be reduced while the product quality is stable.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] As Figures 1-4 shown, the present invention provides a technical solution: a punching fixture for stainless steel pipes, including a fixed die base 1 and a movable die base 2. The fixed die base 1 is fixed on the workbench surface 3. The top of the fixed die base 1 is slidably provided with a vertically oriented punch 4. A fixed die core 5 is horizontally arranged on the fixed die base 1 along a direction perpendicular to the punch 4. A blanking hole 51 matching the punch 4 is arranged on the fixed die core 5 along the movement direction of the punch 4. The blanking hole 51 extends vertically downward. A scrap belt conveyor 11 is arranged at the bottom of the fixed die base 1 corresponding to the lower part of the blanking hole 51, which is convenient for handling waste materials.

[0025] The movable die base 2 is arranged opposite to the fixed die base 1. The movable die core 6 is rotatably connected to the movable die base 2 through a bearing, and the movable die core 6 and the fixed die core 5 are distributed on the same horizontal axis. The opposite ends of the movable die core 6 and the fixed die core 5 are both frustum-shaped, which is convenient for feeding. A template 61 distributed circumferentially is arranged on the movable die core 6, and a positioning cavity for inserting a pipe fitting is formed between the movable die core 6 and the template 61. The clamping plate 611 is detachably installed inside the template 61 through bolts, which can avoid the frequent contact and wear between the clamping plate 611 and the stainless steel pipe and is convenient for replacement after damage. Spring ball plungers 62 distributed circumferentially are arranged on the movable die core 6, and the template 61 and the spring ball plungers 62 are staggered to clamp the stainless steel pipe to be processed sleeved on the movable die core 6.

[0026] The movable die base 2 is slidably arranged on the workbench surface 3 along the axial direction of the movable die core 6. A slide block 21 is arranged at the bottom of the movable die base 2. The slide block 21 is slidably arranged on the slide rail 31 embedded in the workbench surface 3. Mounting holes 32 are arranged on the workbench surface 3 at intervals along the length direction of the slide rail 31. A screw can be arranged at the bottom of the slide rail 31 and inserted into the mounting hole 32 and locked by a nut for installation. The installation position of the slide rail 31 along the length direction can be adjusted through the mounting hole 32, so that the slide rail 31 can extend outwards to increase the length of the working area, which is convenient for processing pipes with longer lengths.

[0027] A translation drive cylinder 7 for driving the movable die holder 2 to slide horizontally is arranged on the workbench surface 3. The translation drive cylinder 7 is horizontally arranged along the sliding direction of the movable die holder 2. A rotary drive motor 8 for driving the movable die core 6 to rotate around the horizontal axis of the movable die core 6 is arranged on the movable die holder 2. The output end of the rotary drive motor 8 is connected to the movable die core 6.

[0028] During use, when the translation drive cylinder 7 is reset, the movable die holder 2 moves away from the fixed die holder 1 to provide a feeding space. Manually feed the pipe body into the positioning cavity for pipe fitting insertion formed by the movable die core 6 and the template 61. The pipe body is stably clamped by the template 61 and the spring ball head plunger 62. Then, the translation drive cylinder 7 drives the movable die holder 2 to drive the whole to move horizontally towards the fixed die holder 1, so that the other end of the pipe body is installed on the fixed die core 5 and enters the processing area below the punch 4. The punch 4 punches down the hole pattern once and resets upward once. The rotary drive motor 8 drives the movable die core 6 to rotate a set angle on the movable die holder 2. The movable die core 6 drives the pipe body clamped on it to rotate to the position for processing the hole pattern at another angle. The punch 4 continues to punch down and process the hole pattern and then resets. After a circle of ventilation holes is processed, the translation drive cylinder 7 is reset again, and the operator unloads the pipe body.
