Description

Technical Field

[0001] This utility model particularly relates to a square aluminum punching device. Background Technology

[0002] Square aluminum tubes and profiles are widely used in building curtain walls, machinery frames, display racks, and furniture manufacturing due to their excellent structural strength and lightweight properties. In these applications, in addition to conventional end-face connections, more and more scenarios require punching holes in the side walls of aluminum profiles to achieve functions such as lateral connections, pipeline passage, ventilation and heat dissipation, or specific aesthetics.

[0003] Most mainstream specialized fixtures and devices currently on the market are optimized for vertical drilling or punching. For example, using a clamping plate to press the profile onto a worktable, followed by machining from top to bottom by a vertical drilling machine or machining center, is suitable for drilling holes on the upper surface of the profile, but it cannot efficiently and accurately complete the sidewall machining. Another example is using flat-jaw vises or V-blocks to hold square aluminum, where the side space is often blocked by the fixture body, preventing the punching mechanism from reaching the machining position, or requiring very complex and expensive angle head attachments. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a square aluminum punching device.

[0005] To solve the aforementioned technical problems, this utility model adopts the following technical solution: A square aluminum punching device includes a base and a side punching mechanism. A vertical frame is mounted on the base, and a first mounting bracket is fixed to the vertical frame while a second mounting bracket is slidably mounted thereon. The first and second mounting brackets are arranged opposite each other, each having a first L-shaped limiting part and a second L-shaped limiting part. A driving device is provided on the vertical frame to drive the second mounting bracket closer to or further away from the first mounting bracket, such that the first and second L-shaped limiting parts together form a limiting space for clamping a square aluminum tube, with the sidewall of the clamped square aluminum tube facing the side punching mechanism. The side punching mechanism is horizontally mounted and used to punch the sidewall of the square aluminum tube facing it.

[0006] Preferably, the first mounting bracket includes two parallel and spaced-apart first mounting plates fixed to the upright, each of the two first mounting plates having a first L-shaped opening, the two first L-shaped openings together constituting the first L-shaped limiting part.

[0007] Preferably, a slide bar is horizontally fixed on the upright frame, and a connecting frame for connecting to the second mounting frame is slidably disposed on the slide bar. The driving device is disposed on the upright frame and is used to drive the second mounting frame to move the connecting frame along the slide bar.

[0008] Preferably, the second mounting bracket includes symmetrically arranged second mounting plates, and a fastener is connected between the two second mounting plates. The fastener is connected to the connecting bracket, and each of the two second mounting brackets has a second L-shaped opening. The two second L-shaped openings together constitute the second L-shaped limiting part.

[0009] Preferably, each second mounting plate is also connected to a base plate at its lower end, each base plate is slidably connected to the base, and a crossbar is connected between the two base plates.

[0010] Preferably, the driving device is a telescopic motor.

[0011] Preferably, anti-slip ridges with serrated surfaces are provided on the inner sidewalls of the first L-shaped opening and the second L-shaped opening.

[0012] The beneficial effects of this utility model are: This invention utilizes a limiting space formed by two opposing L-shaped limiting parts to simultaneously grip a square aluminum tube from four directions (top, bottom, left, and right), achieving "four-sided positioning." This structure is particularly optimized to resist the enormous torsional and impact forces generated during lateral punching, effectively preventing workpiece rotation and movement during processing, and fundamentally ensuring the machining accuracy of the sidewall holes. Unlike traditional top-down machining fixtures, the L-shaped limiting clamping method of this application allows the aluminum tube to be "suspended" above the base, providing ample and interference-free working space for the lateral punching mechanism.

[0019] A square aluminum punching device includes a base 1 and a side punching mechanism 2. A stand 3 is provided on the base 1. A first mounting bracket is fixed on the stand 3 and a second mounting bracket is slidably provided on the stand 3. The first mounting bracket and the second mounting bracket are arranged opposite to each other and are respectively provided with a first L-shaped limiting part and a second L-shaped limiting part. A driving device 4 is provided on the stand 3 to drive the second mounting bracket to move closer to or away from the first mounting bracket, so that the first L-shaped limiting part and the second L-shaped limiting part together form a limiting space 5 for clamping a square aluminum tube, and the side wall of the clamped square aluminum tube faces the side punching mechanism 2. The side punching mechanism 2 is horizontally installed and is used to punch the side wall of the square aluminum tube facing it.

[0020] Furthermore, the first mounting frame includes two parallel and spaced first mounting plates 61 fixed to the upright frame 3. Each of the two first mounting plates 61 has a first L-shaped opening 62, and the two first L-shaped openings 62 together constitute the first L-shaped limiting part.

[0021] Furthermore, a sliding rod 7 is horizontally fixed on the upright frame 3, and a connecting frame 8 for connecting to the second mounting frame is slidably arranged on the sliding rod 7. The driving device 4 is arranged on the upright frame 3 and is used to drive the second mounting frame to move the connecting frame 8 along the sliding rod 7.

[0022] Furthermore, the second mounting bracket includes symmetrically arranged second mounting plates 91, and a fixing member 92 is connected between the two second mounting plates 91. The fixing member 92 is connected to the connecting bracket 8. Both second mounting brackets are provided with second L-shaped openings 93, and the two second L-shaped openings 93 together constitute the second L-shaped limiting part.

[0023] Furthermore, each second mounting plate 91 is also connected to a base plate 10 at its lower end, each base plate 10 is slidably connected to the base 1, and a crossbar 11 is connected between the two base plates 10.

[0024] Furthermore, the driving device 4 is a telescopic motor.

[0025] Furthermore, anti-slip ridges 70 with serrated surfaces are provided on the inner sidewalls of the first L-shaped opening 62 and the second L-shaped opening 93.

[0026] The working principle of this utility model is as follows: In Embodiment 1, the upright frame 3 is vertically fixed to the rear of the base 1. The lateral punching mechanism 2 is mounted on the base 1 via a bracket and is located on one side of a preset processing station, with its punch facing the front of the limiting space 5. The first mounting frame is fixed to the upright frame 3 by bolts. In a specific embodiment, the first mounting frame may include two parallel and spaced-apart first mounting plates 61. Each first mounting plate 61 has a first L-shaped opening 62 machined on it, and the two first L-shaped openings 62 together constitute the first L-shaped limiting part.

[0027] Based on the above technical solution, the second mounting bracket is arranged opposite to the first mounting bracket and can slide on the base 1. To achieve smooth sliding, a smooth sliding rod 7 is horizontally fixed on the upright 3. A connecting bracket 8 is slidably fitted onto the sliding rod 7. The second mounting bracket includes two symmetrically arranged second mounting plates 91, which are connected as a whole by a fastener 92, which is then fixedly connected to the connecting bracket 8. Each second mounting plate 91 has a second L-shaped opening 93 machined on it, and the two second L-shaped openings 93 together constitute a second L-shaped limiting part. This design is mainly because the huge reaction force generated during punching will attempt to cause the second mounting bracket to twist or jam. The guide of the sliding rod 7 can resist this lateral force and torque, ensuring that the second mounting bracket always slides smoothly along a straight line without the risk of shaking or "jamming".

[0028] The driving device 4 is the telescopic motor in this embodiment. Its cylinder is fixed on the upright frame 3, and the end of its piston rod is connected to the connecting frame 8. When the telescopic motor is activated, it can drive the connecting frame 8 to move the entire second mounting frame linearly along the slide rod 7, thereby moving closer to or away from the first mounting frame. This design is adapted to square aluminum tubes with different cross-sectional dimensions, and for workpieces of various specifications within a certain size range, there is no need to change the fixture.

[0029] Based on the above technical solution, anti-slip ridges 70 with serrated surfaces are provided on the inner sidewalls of the first L-shaped opening 62 and the second L-shaped opening 93 to increase the friction with the surface of the aluminum tube.

[0030] In use, the operator places a square aluminum tube onto the first L-shaped limiting part. The telescopic motor is activated, its piston rod extends, pushing the second mounting bracket forward until the second L-shaped limiting part contacts the aluminum tube. Together with the first L-shaped limiting part, the second L-shaped limiting part clamps the aluminum tube tightly within the formed rectangular limiting space 5. At this point, the front surface of the aluminum tube (the surface facing the lateral punching mechanism) is completely exposed, without any obstruction. The lateral punching mechanism 2 is then activated, and the punch quickly strikes, punching a round hole in the side wall of the aluminum tube. After punching, the punch retracts, the telescopic motor piston rod contracts, and the second mounting bracket retracts to release the aluminum tube, allowing the operator to remove the finished product.

[0031] Based on the above technical solution, this embodiment has been optimized to further improve the stability and load-bearing capacity of the second mounting bracket during the sliding process. A base plate 10 is also fixedly connected to the lower end of each second mounting plate 91. The bottoms of these two base plates 10 are in direct contact with the upper surface of the base 1 and can slide. At the same time, a crossbar 11 is connected between the two base plates 10. In this way, the second mounting bracket forms two support points, one above and one below, through the cooperation of the upper connecting frame 8 with the sliding rod 7 and the lower base plate 10 with the base 1. This greatly enhances the rigidity and stability of the moving parts, and is especially suitable for processing long or heavy aluminum profiles.

[0032] This invention utilizes a limiting space formed by two opposing L-shaped limiting parts to simultaneously grip a square aluminum tube from four directions (top, bottom, left, and right), achieving "four-sided positioning." This structure is particularly optimized to resist the enormous torsional and impact forces generated during lateral punching, effectively preventing workpiece rotation and movement during processing, and fundamentally ensuring the machining accuracy of the sidewall holes. Unlike traditional top-down machining fixtures, the L-shaped limiting clamping method of this application allows the aluminum tube to be "suspended" above the base, providing ample and interference-free working space for the lateral punching mechanism.

[0033] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
