Technical Field
[0001] The utility model relates to the field of stamping dies, in particular to a cold stamping die structure for square tubes. Background Technique
[0002] Square tubes, also known as square steel pipes, are steel pipes with a square cross-section and are widely used in many fields such as construction, machinery manufacturing, and furniture. Due to their excellent structural characteristics and wide application fields, square tubes have become an indispensable important material in modern industry and construction. To meet the usage requirements, sometimes it is necessary to punch holes in square tubes, and at this time, a cold stamping die structure is required to punch the square tubes.
[0003] However, when the existing cold stamping die structure punches holes, generally, it is necessary for workers to mark the square tubes manually first. The manual marking process is easily affected by the skill level and experience of the operators, resulting in inaccurate markings, and thus causing deviations during punching; in addition, relying on manual marking not only takes time, but also is more likely to cause inconsistencies during mass production, affecting production efficiency.
[0004] Therefore, in view of the above problems, a cold stamping die structure for square tubes is proposed. Content of the Utility Model
[0005] In order to make up for the deficiencies of the existing technology and solve the problems raised in the background technique, the utility model proposes a cold stamping die structure for square tubes.

[0007] The stamping component is installed on the workbench. The stamping component includes a pair of oppositely arranged mounting seats. In the middle of the tops of the two mounting seats, a top plate is fixedly installed. A stamping hole is opened in the middle of the top plate. Above the workbench, a hydraulic driving device is fixedly installed. The bottom of the telescopic end of the hydraulic driving device is fixedly installed with a connecting plate. In the middle of the bottom end of the connecting plate, a stamping head is fixedly installed. A die core is arranged between the two mounting seats. The die core is arranged in an inverted U shape. A through hole is opened in the middle of the die core. The square tube body is movably sleeved outside the die core;
[0008] The limiting component is arranged on the side of the stamping component, and the punching position on the square tube body is positioned through the limiting component.
[0009] Preferably, the limiting component is composed of a plurality of limiting units, a first sliding rod and a second sliding rod. Each limiting unit includes a moving block. An installation hole is formed at one end of the moving block. The first sliding rod slidably penetrates through the installation hole. An activity groove is formed at one end of the moving block away from the installation hole. A sleeve is arranged in the middle of the activity groove. The second sliding rod slidably penetrates through the middle of the sleeve. A baffle is movably installed in the activity groove. The end of the baffle is movably sleeved outside the sleeve.
[0010] Preferably, a fixing rod is fixedly connected to the end of the mold core. One side of the top of the workbench is fixedly connected with a side plate. The fixing rod is fixedly connected to the side plate.
[0011] Preferably, guide wheels are respectively rotatably installed at the front and rear ends of the opposite side edges of the two mounting seats.
[0012] Preferably, a guide rod is fixedly connected to the workbench at a position outside the mounting seat. A guide hole adapted to the guide rod is formed on the connecting plate. The guide rod is slidably arranged in the guide hole.

[0016] The beneficial effects of the present utility model are as follows:
[0017] 1. By providing a stamping component in the present utility model, punching operations can be performed on the square tube body. When in use, the square tube body is inserted into the middle of the mounting seat from one end, and the square tube body is sleeved outside the mold core. Then, the hydraulic driving device drives the connecting plate and the punching head to move downward. The punching head enters the inner side of the top plate from the punching hole and performs punching operations on the square tube body. The waste generated by punching falls into the inner cavity of the mold core from the through hole, and when the square tube body is taken out, the waste can be taken out at the same time, which is convenient for cleaning the waste.
[0018] 2. The utility model determines the punching position by setting a limiting component. When punching the square pipe body, first rotate the baffles in multiple limiting units upward, then sleeved the square pipe body on the die core, reset the baffle that is farthest from the feeding port of the square pipe stamping component, and slide the square pipe body along the die core until it abuts against the lowered baffle. Then rotate all the other baffles in the reverse direction and place them on the top of the square pipe body. After each punching, retreat the square pipe body in the direction of the feeding port. When the end of the square pipe body passes by the baffle placed on the top, under the action of gravity, the baffle automatically falls and resets. Then push the square pipe body forward again to make it abut against the fallen baffle, and then perform punching again, which is convenient for quickly determining the punching position.
