Description
Technical Field
[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for aluminum tube production. Background Art
[0002] Punching refers to the process of punching holes to meet different needs, including: eight-shaped holes, hexagonal holes, perforated plates, long holes, square holes, round holes, perforated plate nets, triangular holes, etc. Compared with plate punching, although there are many similarities in deformation properties and characteristics, the aluminum tube is a hollow cylindrical blank. When punching, the tube wall that the convex and concave dies contact is an isolated surface instead of a flat surface like the plate, so special process measures and mold structure forms are required.
[0003] For example, an aluminum tube punching device with the authorization announcement number "CN214349005U" can directly rotate the inner screw sleeve to disengage from the shelf groove and tilt it after the device is stable, and then rotate the threaded shaft to disengage and touch the ground to form an oblique support, thereby reinforcing the stability of the four legs and the device. By designing a rotating adjustment screw, the aluminum tube can be pushed to move until it is clamped by the stop plate to position the aluminum tube. The concave clamp seat can keep the aluminum tube from falling out, making the aluminum tube processing more stable. However, the aluminum tube punching device punches the aluminum tube through the punching head. Since the position of the punching head is fixed, when it is necessary to punch other positions of the aluminum tube, it is impossible to punch other positions of the aluminum tube, thereby increasing the working limitations. At the same time, the aluminum tube punching device limits the aluminum tube by manually rotating the adjustment screw by the operator. Each time processing, the operator needs to manually fix it. When there are many aluminum tubes to be processed, it is necessary to consume more physical strength of the operator, thereby increasing the manual labor. Utility Model Content

At the same time, the aluminum tube punching device limits the aluminum tube by manually rotating an adjusting screw by an operator. Each time processing is performed, the operator is required to manually fix the aluminum tube. When a large number of aluminum tubes need to be processed, the operator needs to consume more physical strength, thereby increasing the problem of manual labor.

[0010] Preferably, the outer wall of the second shell is fixedly connected to the bent plate, and the right end of the double-sided rack is slidably connected to the slider.

[0026] Working principle:
[0027] When punching aluminum tubes using a punching device:
[0028] Preparation process:
[0029] The operator first places the aluminum tube to be punched between the two slide plates 306 .
[0030] Aluminum tube limiting process:
[0031] The operator starts the second cylinder 302, and the output end of the second cylinder 302 extends to drive the moving block 303 to move, thereby moving the vertical plate 304. The movement of the vertical plate 304 drives the protruding column 305 to slide along the inclined groove processed on the slide plate 306, thereby driving the slide plate 306 to slide along the outer wall of the fixed column 307. At the same time, the slide plate 306 slides inward along the slide groove processed on the first shell 301. When the outer walls of the slide plate 306 are tightly fitted with both ends of the aluminum tube, the second cylinder 302 is closed, and the operator does not need to manually perform too many operating steps, so that the aluminum tube can be limited without the operator consuming much physical strength.
[0032] Punching head adjustment process:
[0033] The operator starts the power supply of the second motor 702, and the output shaft of the second motor 702 rotates to drive the output shaft of the worm 703 to rotate, thereby driving the two worm wheels 704 to rotate, and driving the double-sided rack 706 to move to the right. When the double-sided rack 706 engages with the incomplete gear 705 below, it drives the double-sided rack 706 to move to the left. The movement of the double-sided rack 706 drives the block 707 to slide along the slide groove processed on the inner wall of the second shell 701. The movement of the double-sided rack 706 drives the slider 6 to slide along the slide groove processed on the bent plate 8. The movement of the slider 6 drives the first motor 5 and the punching head 4 to move. When the punching head 4 moves to the appropriate position, the power supply of the second motor 702 is turned off to enable the punching head 4 to punch holes in different positions of the aluminum tube, thereby reducing working limitations.
[0034] Aluminum tube punching process:
[0035] The operator starts the power supply of the first motor 5, and the output shaft of the first motor 5 rotates to drive the punching head 4 to rotate, and then starts the first cylinder 2. The output end of the first cylinder 2 extends to drive the first shell 301 to move upward, thereby driving the limited aluminum tube to move upward to punch the aluminum tube. When the punching is completed, the output end of the first cylinder 2 moves downward. When the first shell 301 is reset, the power supply of the first cylinder 2 and the first motor 5 is turned off. Then the operator starts the second cylinder 302. The telescopic end of the second cylinder 302 retracts to drive the two slides 306 to move outward synchronously. When the two slides 306 move to the appropriate position, the second cylinder 302 is turned off, and then the operator removes the punched aluminum tube.
