Technical Field

[0001] This utility model belongs to the field of handheld punching machine technology, specifically, it relates to a highly adaptable handheld punching machine. Background Technology

[0002] In today's industrial processing field, handheld punch presses are a commonly used small processing device, widely used for punching various thin sheet materials. Traditional handheld punch presses have certain limitations in design, especially the structural design of the steel plate placement area is not flexible enough.

[0003] Chinese patent application number CN202420746428.X discloses a handheld punch press, including a first cylinder body, a die head sleeve, and a punch base. A rear cover is connected to the rear surface of the first cylinder body by screw threads. A second pneumatic cylinder body is integrally formed at one end of the first cylinder body. An internal air supply chamber is opened inside the punch base. An adjusting component is provided inside the internal air supply chamber. A booster cylinder is installed at one end of the second pneumatic cylinder body. A pressure supply component is provided inside the first cylinder body. A linkage component is provided inside the second pneumatic cylinder body. A punch head is installed at one end of the linkage component.

[0004] In the aforementioned patent design, when using an existing handheld punch press to punch steel plates, the width of the steel plate placement area is usually fixed, while the thickness of the steel plates to be punched varies. Therefore, when processing thicker steel plates, the steel plate cannot be stably fixed in the appropriate position because the width of the placement area is not adjustable. This causes the steel plate to easily shift during the punching process, resulting in deviations in the punching position and uneven roughness of the punching edges. This affects the punching effect and product quality, increases the scrap rate, and makes it difficult to meet the needs of current diversified production.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0036] Example 1

[0037] Please refer to Figure 1-5 A highly adaptable handheld punching machine includes: a handheld punching machine body 1, a die head sleeve 2 fixedly connected to one end of the handheld punching machine body 1, a placement groove 3 formed on the die head sleeve 2, a punching groove 4 formed on one side of the die head sleeve 2, an installation groove 5 formed on one side of the inner wall of the placement groove 3, a fixing plate 6 slidably fitted to the inner wall of the installation groove 5, a mating block 7 fixedly connected to one side of the fixing plate 6, and an adjustment mechanism 8 provided inside the installation groove 5. The mating block 7 slidably fits to one side of the inner wall of the placement groove 3, and the punching groove 4 mates with the output end of the handheld punching machine body 1. A mounting shell 12 is fixedly connected to the upper side of the die head sleeve 2, a slider 13 is slidably and elastically fitted to the inner wall of the mounting shell 12, a connecting rod 14 is fixedly connected to one side of the slider 13, and a limit block 15 is fixedly connected to one end of the connecting rod 14, the limit block 15 mates with multiple scale blocks 10.

[0038] Implementation process: The width of the steel plate on the die head sleeve 2 is adjusted by adjusting mechanism 8. During the adjustment process, scale block 10 rotates with knob 86. The adjustment range can be observed directly through indicator block 11. When the adjustment is in the appropriate position, slider 13 pushes limit block 15 to lock the corresponding scale block 10 under the elastic action in mounting shell 12, fixing the position of knob 86 and ensuring the stability of the width of the placement groove. After preparation, the steel plate is placed in the placement groove 3, and the handheld punching machine body 1 is started. Its output end punches the steel plate through the punching groove 4.

[0039] Benefits of implementation: The combination of knob 86, scale block 10 and indicator block 11 allows operators to quickly and accurately adjust the width of the placement slot, and limit block 15 further ensures the stability after adjustment, simplifies the operation process and improves work efficiency.

[0040] Example 2

[0041] The adjusting mechanism 8 includes a worm gear 81 rotatably engaged with the lower side of the inner wall of the mounting groove 5. A double-acting lead screw 82 is rotatably engaged with the inner wall of the mounting groove 5. One end of the double-acting lead screw 82 is fixedly connected to a worm wheel 83. Two movable seats 84 are threaded onto the double-acting lead screw 82. A connecting rod 85 is provided between each of the two movable seats 84 and the fixed plate 6. A knob 86 is fixedly connected to the upper end of the worm gear 81. The worm gear 81 meshes with the worm wheel 83, and the two ends of the connecting rod 85 are rotatably engaged with the fixed plate 6 and the movable seats 84, respectively. A sliding groove 9 is provided on one side of the inner wall of the mounting groove 5, and the two movable seats 84 are slidably engaged with the inner wall of the sliding groove 9. Multiple scale blocks 10 are evenly mounted on the outer side of the knob 86, and an indicator block 11 is provided on one side of the mold head sleeve 2. The multiple scale blocks 10 cooperate with the indicator block 11.

[0042] Implementation process: When it is necessary to adjust the placement width according to the thickness of the steel plate, the operator turns the knob 86, which drives the worm 81 to rotate synchronously. Since the worm 81 meshes with the worm wheel 83, the rotation of the worm 81 causes the worm wheel 83 to drive the double-acting screw 82 to rotate. There are two moving seats 84 threaded on the double-acting screw 82. During the rotation of the screw, the two moving seats 84 will move towards or away from each other along the double-acting screw 82 under the guidance of the slide groove 9. The moving seats 84 are rotatably connected to the fixed plate 6 through the connecting rod 85, which in turn pushes the fixed plate 6 to slide in the mounting groove 5. The mating block 7 also slides on the inner wall of the placement groove 3, thereby realizing the adjustment of the width of the placement groove 3.

[0043] Benefits of implementation: The width of the placement slot 3 can be flexibly changed by adjusting mechanism 8 to adapt to steel plates of different thicknesses, effectively solving the problem of fixed width of steel plate placement in traditional handheld punching machines, and greatly improving the equipment's processing capacity for various specifications of plates.
