Description

Technical Field

[0001] The utility model relates to the field of bending machines, in particular to an aluminum strip bending machine. Background Art

[0002] The aluminum bar bending machine includes a workbench, and an aluminum bar limit block, a corner pressing cylinder, a bending assembly, and a top pressing assembly installed on the workbench. When the aluminum bar is loaded, it passes through the aluminum bar limit block and then the bending assembly. Then, when working, the corner pressing cylinder presses the aluminum bar at the bending position, and then the top pressing assembly works to press the aluminum bar against the workbench. Finally, the bending assembly works to bend the aluminum bar.

[0003] The entire bending process is highly automated, but existing small-scale bending machines mostly rely on manual labor to load aluminum bars. Therefore, after the aluminum bars are bent, they also need to be removed from the workbench manually. In actual operation, due to the unreasonable arrangement of the top clamping assembly on the existing aluminum bar bending machine, the pressure plate on the top clamping assembly only moves upward after releasing the pressure on the aluminum bar, and the pressure plate is always directly above the aluminum bar.

[0004] Therefore, when the operator takes out the aluminum bar, he needs to lift the aluminum bar first to separate the aluminum bar from the aluminum bar limit block, and then move the aluminum bar out from the horizontal empty space to the side. The reason for this step is that the pressure plate is directly above the aluminum bar, which increases the unloading operation of the aluminum bar, increases the difficulty of operation, and reduces production efficiency. In addition, the angle of the pressure plate of the existing aluminum bar bending machine remains unchanged. Every time it is pressed on the aluminum bar, the aluminum bar will form friction on the bottom surface of the pressure plate when it is bent. Over time, it will cause wear and depression at a single position on the bottom surface of the pressure plate, thereby affecting the stability of the pressure plate pressing. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technical problems, the purpose of the utility model is to provide an aluminum bar bending machine that can also translate the pressure plate toward the outside of the workbench during the process of raising the pressure plate after the bending is completed, so that the pressure plate avoids from above the aluminum bar, and can intermittently drive the pressure plate to rotate to avoid continuous wear of a single position on the bottom surface of the pressure plate.

[0006] In order to solve the problems of the prior art, the technical solutions of the present utility model are as follows:

[0007] The aluminum strip bending machine comprises a workbench, a support frame is fixed on one side of the top surface of the workbench, and a guide rod cylinder is fixed in the middle of the crossbeam of the support frame;

[0008] A connecting plate is fixed to the protruding end of the guide rod cylinder, an extension plate is slidably mounted on the bottom surface of the connecting plate, the extension plate extends from the inner side of the support frame to the top surface of the workbench, and a pressure plate is mounted on the bottom surface of the extension plate away from the support frame.

[0009] The two side plates of the support frame are provided with translation components for driving the extension plate to slide along the direction passing through the inner side of the support frame.

[0010] Preferably, the translation assembly includes drive grooves respectively opened on the two side panels of the support frame, and the drive grooves on the two side panels are opposite to each other. The bottom surface of the extension plate is rotatably connected to a drive column through a bearing, and the two ends of the drive column are respectively inserted into the two drive grooves.

[0011] Preferably, the driving groove comprises a vertical groove located at the lower part and an inclined groove located at the upper end of the vertical groove and connected to the vertical groove, and the inclined groove is arranged to be inclined upward from an end close to the pressure plate to an end away from the pressure plate.

[0012] Preferably, the pressure plate includes a rotating shaft fixed in the middle of the top surface of the pressure plate, the upper end of the rotating shaft is rotatably connected to the extension plate through a bearing, a motor is fixed to one end of the top surface of the extension plate close to the rotating shaft, and the upper end of the rotating shaft is fixed to the output end of the motor.

[0013] Preferably, a slide bar is symmetrically fixed to the bottom surface of the connecting plate, a slide rail is symmetrically fixed to the top surface of the extension plate, and the slide bar is slidably connected to the slide rail.

[0014] Preferably, a reinforcement ring is fixed on the bottom surface of the extension plate at a position facing the pressure plate, and the upper end of the rotating shaft is rotatably connected to the inner wall of the reinforcement ring.

[0015] Compared with the prior art, the advantages of the present invention are as follows:

[0016] 1. After the bending work is completed, the extended end of the guide rod cylinder contracts, driving the connecting plate, extension plate and pressure plate to rise. During the rising process, the extension plate can slide toward the inner side of the support frame through the translation component, so that the pressure plate is moved away from directly above the aluminum bar. Therefore, when the aluminum bar is subsequently unloaded, the employee only needs to directly pull up and remove the aluminum bar without moving the aluminum bar horizontally. This reduces the number of aluminum bar unloading steps and improves the production efficiency of aluminum bars.

[0017] 2. The translation assembly and the connection plate are mechanically linked to each other, and the extension plate is controlled by the extension force of the guide rod cylinder, which reduces the investment in power equipment, thereby greatly reducing the production, manufacturing and operation and maintenance costs of the equipment, making it more suitable for small production enterprises to put into use;

[0018] 3. By rotatably connecting the pressure plate with the extension plate, and setting a motor and a rotating shaft to drive the pressure plate to intermittently rotate a certain angle, all positions of the bottom surface of the pressure plate can evenly withstand the wear of the bending of the aluminum bar, avoiding the occurrence of continuous wear at a single position on the bottom surface of the pressure plate, so that the shape of the bottom surface of the pressure plate can always remain flat, thereby ensuring the stability of the clamping and extending the service life of the pressure plate.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] For example 1, please refer to Figures 1 to 3 , this embodiment provides an aluminum bar bending machine, including a workbench 1, on the top surface of which are mounted an aluminum bar limit block, a corner pressing cylinder, and a bending assembly;

[0026] When the aluminum bar is working, the two aluminum bar limit blocks are used to limit the horizontal direction of the aluminum bar. When loading, the aluminum bar passes between the two aluminum bar limit blocks;

[0027] The corner pressing cylinder is extended so that its extended end presses against the outer wall of the aluminum bar, and the position where the aluminum bar is pressed is the inflection point when it bends;

[0028] The bending assembly is the main structure that provides the force for bending the aluminum strip and completes the bending work of the aluminum strip. The above structures are all existing technologies, so they will not be described again.

[0029] A support frame 2 is fixed to one side of the top surface of the workbench 1. The support frame 2 is composed of side plates 202 located on both sides and a crossbeam 201 located between the upper ends of the two side plates 202. The side plates 202 are fixed to the top surface of the workbench 1. A guide rod cylinder 3 is fixed in the middle of the crossbeam 201.

[0030] A connecting plate 4 is fixed to the extended end of the guide rod cylinder 3, an extension plate 5 is slidably mounted on the bottom surface of the connecting plate 4, a slide bar 12 is symmetrically fixed to the bottom surface of the connecting plate 4, and a slide rail 11 is symmetrically fixed to the top surface of the extension plate 5, the slide bar 12 is slidably connected to the slide rail 11, and the extension plate 5 is slidably connected to the connecting plate 4 through the slide rail 11 and the slide bar 12;

[0031] The extension plate 5 extends from the inner side of the support frame 2 to the top surface of the workbench 1. A pressure plate 6 is installed on the bottom surface of the extension plate 5 away from the support frame 2. A driving groove 7 is provided on both side plates 202, and the driving grooves 7 on the two side plates 202 are opposite to each other. The bottom surface of the extension plate 5 is rotatably connected to a driving column 8 through a bearing. The two ends of the driving column 8 are respectively inserted into the two driving grooves 7. The driving groove 7 includes a vertical groove at the bottom and an inclined groove at the upper end of the vertical groove and connected to the vertical groove. The inclined groove is inclined upward from the end close to the pressure plate 6 to the end away from the pressure plate 6.

[0032] After the aluminum strip is loaded into place and the corner pressing cylinder presses the aluminum strip tightly, the protruding end of the guide rod cylinder 3 can be driven to extend, so that the connecting plate 4 drives the extension plate 5 and the pressure plate 6 to move downward. In the process of downward movement, the driving column 8 slides along the inner wall of the inclined groove, pushing the extension plate 5 to slide down at the bottom of the connecting plate 4 while sliding toward the side close to the aluminum strip, and finally makes the pressure plate 6 face the position of the aluminum strip of the corner pressing cylinder pressing column until the driving column 8 reaches the vertical groove, and then the guide rod cylinder 3 continues to extend until the pressure plate 6 is finally pressed against the surface of the aluminum strip, completing the pressing work, and then the bending work is carried out;

[0033] After the bending is completed, the guide rod cylinder 3 contracts, the connecting plate 4 rises, and the extension plate 5 slides toward the inside of the support frame 2 while rising, so that the pressure plate 6 avoids from above the aluminum bar, which is convenient for workers to remove the aluminum bar. During the aluminum bar unloading process, they only need to pull it directly upwards and then remove it vertically, without adding the step of moving it in the horizontal direction, which greatly reduces the operation steps of aluminum bar unloading and improves processing efficiency.

[0034] For example 2, please refer to Figure 4 This embodiment provides a further technical solution based on the first embodiment. The pressure plate 6 includes a rotating shaft 9 fixed at the middle position of the top surface of the pressure plate 6. The upper end of the rotating shaft 9 is rotatably connected to the extension plate 5 through a bearing. A reinforcing ring 13 is fixed on the bottom surface of the extension plate 5 facing the pressure plate 6. The upper end of the rotating shaft 9 is rotatably connected to the inner wall of the reinforcing ring 13, which improves the stability of the connection of the rotating shaft 9. A motor 10 is fixed to one end of the top surface of the extension plate 5 close to the rotating shaft 9, and the upper end of the rotating shaft 9 is fixed to the output end of the motor 10.

[0035] According to the setting, the motor 10 can drive the rotating shaft 9 to rotate a certain angle after each bending of the aluminum bar or after multiple bending of the aluminum bar, thereby driving the pressure plate 6 to rotate a certain angle, and then continue to press the aluminum bar. In this way, each bending of the aluminum bar causes wear on the bottom surface of the pressure plate 6, and since the pressure plate 6 can rotate intermittently, each position of the bottom surface of the pressure plate 6 can withstand wear evenly, and there will be no severe wear at a single position, which will cause a single position to be concave and the bottom surface of the pressure plate 6 to be uneven, thereby ensuring the stability of the pressing and improving the service life of the pressure plate 6.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
