Description

Technical Field

[0001] The present invention relates to the technical field related to the angle adjustment of a bending machine, and specifically to a bending device for magnesium alloy manufacturing. Background Art

[0002] A bending machine is a device used for bending metal plates. It changes the shape of the metal plate by applying force and pressure, bending it into the required angle or shape. When using a bending machine, the operator needs to adjust the clamping device, select a suitable die according to specific process requirements and bending drawings, and set corresponding parameters (such as bending angle, bending force, etc.), and then start the machine for bending processing. The bending devices for magnesium alloy manufacturing in the prior art have the following defects:

[0003] 1. In the prior art, when the bending device for magnesium alloy manufacturing is in use, the bending radius is mostly fixed. Different bending angles require different bending radii. An inappropriate bending radius will greatly reduce the service life at the bent corner. The traditional method is to process special bending punches of different specifications or process on bending machines with different bending degrees; therefore, during the manufacturing process of magnesium alloy plates with various different bending degrees, the number of bending machines required will increase or multiple bending punches need to be replaced, resulting in low work efficiency and high work costs.

[0004] 2. In the prior art, when adjusting the angle of the bending punch, it is usually adjusted manually, and it is difficult to accurately and quickly adjust the angle of the bending punch, thus affecting the bending efficiency of the magnesium alloy plate; and after the angle adjustment of the bending punch is completed, when stamping and bending the magnesium alloy plate, the inside of the bending punch is basically empty, so it is easy for the bending punch to rotate and deform when subjected to a large external force, thus affecting the bending effect of the magnesium alloy plate.

[0005] 3. In the prior art, before stamping and bending the magnesium alloy plate, it is necessary to clamp and fix both sides of the magnesium alloy plate to prevent the magnesium alloy plate from deforming during stamping and bending; however, the existing clamping components cannot adjust the angle of the clamping components along with the deformed sides of the magnesium alloy plate during bending, thus affecting the stamping and bending effect of the magnesium alloy plate, and the clamping components accurately reset to the horizontal state, thus affecting the subsequent stamping work of the magnesium alloy plate. Summary of the Invention

[0006] The purpose of the present invention is to provide a bending device for magnesium alloy manufacturing to overcome the above-mentioned defects in the prior art.

The upward movement of the two sliding plates drives the two second placing plates to rotate and move through two pairs of second rotating plates respectively; when the sliding plate moves upward and contacts the positioning block, the sliding plate stops moving. At this time, the two first placing plates and the two second placing plates are in a horizontal state, so as to facilitate the next bending deformation of the magnesium alloy plate;

[0020] In a bending device for manufacturing magnesium alloy of the present invention, a stamping assembly is provided. The rotation of the lead screw in the stamping assembly drives the moving block to move, so that the up and down movement degree of the moving block can be accurately controlled by controlling the number of turns of the lead screw rotation, so as to accurately control the angle between the two stamping plates, so as to quickly adjust the angle between the two stamping plates according to the required stamping angle; then, the upper planes of a number of first elastic bumps contact and cooperate with the lower planes of a number of second elastic bumps, and the lower planes of the first elastic bumps contact the inclined surfaces of the upper parts of the second elastic bumps, so that the moving block can move upward smoothly and the downward movement of the moving block is restricted, avoiding the situation that the two stamping plates rotate inward during the stamping of the magnesium alloy plate; finally, after the water bag is filled with solution, it supports between the two stamping plates, further avoiding the situation that the two stamping plates rotate inward during the stamping of the magnesium alloy plate;

[0043] Preferably, a spring 42 is connected between the upper side of each rubber block 41 and the inner upper side of the slide groove 38 .

[0044] Preferably, two positioning blocks 43 are fixedly disposed on one side of the two first fixing plates 31 facing each other.

[0045] In the initial state, the two second electric telescopic rods 44 are in an extended state, the four springs 42 are in a stretched state to generate elastic force, and the slide plate 39 is resisted by the positioning block 43 and is difficult to move upward, so that the two first placement plates 32 and the two second placement plates 49 are in a horizontal state.

[0046] Specific usage method of the present invention: The staff places the magnesium alloy plate on the upper sides of two second placing plates 49, and makes both sides at the two ends of the magnesium alloy plate located inside four L-shaped plates 33 respectively. Then, the staff rotates four bolts 34. By the rotation of the bolts 34 in threaded contact with the upper parts of the L-shaped plates 33, the pressing plates 35 are driven to move downward. The four pressing plates 35 move downward to clamp and fix the four corners of the magnesium alloy plate respectively. Among them, when the pressing plates 35 move downward, the rubber plates 36 are driven to move downward, so that the rubber plates 36 are in pressing contact with the magnesium alloy plate.

[0047] Secondly, the staff starts the motor 19. The start of the motor 19 drives the lead screw 20 to rotate. The rotation of the lead screw 20 is in threaded contact with the inside of the moving block 21 through the outside of the lead screw 20, so that the moving block 21 moves vertically up and down in the through hole 18. The up and down movement of the moving block 21 drives two stamping plates 16 to rotate around the fixed rod 15 respectively through the rotation of two first rotating plates 22, so as to adjust the angle between the two stamping plates 16. Among them, when the moving block 21 moves upward in the through hole 18, the upward movement of the moving block 21 drives a plurality of second elastic bumps 25 to move upward. The upward movement of the second elastic bumps 25 makes the upper part of the second elastic bumps 25 in contact with the lower inclined surface of the first elastic bumps 24, so that the second elastic bumps 25 and the first elastic bumps 24 are squeezed and deformed, so as to enable the moving block 21 to move upward smoothly. When the position adjustment of the moving block 21 is completed, at this time, the upper parts of a plurality of first elastic bumps 24 are in contact with the lower planes of the second elastic bumps 25, so as to limit and fix the moving block 21 through the cooperation of a plurality of first elastic bumps 24 and a plurality of second elastic bumps 25, and avoid the situation that the two stamping plates 16 rotate inward during the stamping process of the magnesium alloy plate.

[0048] When the angle between the two stamping plates 16 is adjusted, at this time, two electromagnetic valves 30 are opened, and the solution in the annular water bucket 27 enters the two water sacs 26 through the two telescopic connecting pipes 29, so that the two water sacs 26 are filled with the solution. When the two water sacs 26 are filled with the solution, at this time, the two electromagnetic valves 30 are closed, so as to support between the two stamping plates 16 through the two water sacs 26, and further avoid the situation that the two stamping plates 16 rotate inward during the stamping process of the magnesium alloy plate.

[0049] Next, the first electric telescopic rod 13 extends to drive the first moving plate 14 to move downward. The downward movement of the first moving plate 14 drives the two stamping plates 16 to move downward. The two stamping plates 16 move downward to contact the middle part of the magnesium alloy plate, thereby stamping and bending the magnesium alloy plate. At this time, the middle part of the magnesium alloy plate is under pressure, causing the two second placement plates 49 to rotate relative to each other and the two first placement plates 32 to rotate respectively with the upper ends of the two first fixing plates 31, so as to facilitate the stamping and bending of the magnesium alloy plate. Among them, during the bending deformation process of the magnesium alloy plate, while the two second placement plates 49 rotate and deform relative to each other, the two second placement plates 49 slide on the two second fixing plates 50 respectively, so that the two second placement plates 49 are always located on the lower side of the magnesium alloy plate. The rotation and movement of the two second placement plates 49 can drive the four L-shaped plates 33 to rotate and move respectively, so that the four rubber plates 36 cooperate with the two second placement plates 49 to always clamp and fix the four corners of the magnesium alloy plate, and can change the clamping angle following the angle after the magnesium alloy plate is bent and deformed, improving the effect of the bending deformation of the magnesium alloy plate.

[0050] Meanwhile, the rotation of the second placement plate 49 drives the two second rotating plates 40 to rotate, thereby pushing the sliding plate 39 to move downward in the groove 37. The downward movement of the sliding plate 39 drives the two rubber blocks 41 to squeeze and rub downward in the two sliding grooves 38 respectively, so that the sliding plate 39 moves smoothly in the groove 37, facilitating the smooth and slow rotation of the second placement plate 49, and preventing the two second placement plates 49 from rotating or moving too fast and affecting the bending deformation effect of the magnesium alloy plate. And through the rotation of the two second placement plates 49 to support the bending shape of the lower side of the magnesium alloy plate and cooperate with the two stamping plates 16 to stamp the bending shape of the upper side of the magnesium alloy plate, the magnesium alloy plate is bent and deformed with high precision. Among them, the downward movement of the rubber block 41 further stretches the spring 42 to generate elastic force.

[0051] Finally, when the bending deformation of the magnesium alloy plate is completed, the staff rotates the four bolts 34 to loosen the four corners of the magnesium alloy plate. Then, the staff controls the first electric telescopic rod 13 to contract. The contraction of the first electric telescopic rod 13 drives the two stamping plates 16 to move upward. The staff holds the two second placement plates 49 to prevent the two second placement plates 49 from rotating, and moves the bent magnesium alloy plate into the L-shaped plate 33 on one side, so that the magnesium alloy plate disengages from the L-shaped plate 33 on the other side. The space inside the four L-shaped plates 33 enables the easily removal of the bent magnesium alloy plate. The staff takes out the bent magnesium alloy plate from the two second placement plates 49.

[0052] After the magnesium alloy plate is bent, the staff loosens the two second placing plates 49. The four rubber blocks 41 move upward under the elastic force of the four springs 42 respectively. The upward movement of the four rubber blocks 41 drives the two sliding plates 39 to move respectively. The upward movement of the two sliding plates 39 drives the two second placing plates 49 to rotate and move their positions respectively through the two pairs of second rotating plates 40. When the sliding plate 39 moves upward and contacts the positioning block 43, the sliding plate 39 stops moving. At this time, the two first placing plates 32 and the two second placing plates 49 are in a horizontal state, so as to facilitate the next bending deformation of the magnesium alloy plate.

[0053] In the bending device for manufacturing magnesium alloy of the present invention, a clamping assembly is provided. First, the four pressing plates 35 move downward to clamp and fix the four corners of the magnesium alloy plate respectively. Then, the four rubber plates 36 are in extrusion contact with the magnesium alloy plate, so as to further clamp and fix the two ends of the magnesium alloy plate. Then, during the bending deformation of the magnesium alloy plate, while the two second placing plates 49 rotate and deform relative to each other, the two second placing plates 49 slide on the two second fixing plates 50 respectively, so that the two second placing plates 49 are always located on the lower side of the magnesium alloy plate. The rotation and movement of the two second placing plates 49 can drive the four L-shaped plates 33 to rotate and move respectively, so that the four rubber plates 36 and the two second placing plates 49 cooperate to always clamp and fix the four corners of the magnesium alloy plate, and can change the clamping angle following the angle after the magnesium alloy plate is bent and deformed, improving the effect of bending deformation of the magnesium alloy plate. Finally, the four rubber blocks 41 move upward under the elastic force of the four springs 42 respectively. The upward movement of the four rubber blocks 41 drives the two sliding plates 39 to move respectively. The upward movement of the two sliding plates 39 drives the two second placing plates 49 to rotate and move their positions respectively through the two pairs of second rotating plates 40. When the sliding plate 39 moves upward and contacts the positioning block 43, the sliding plate 39 stops moving. At this time, the two first placing plates 32 and the two second placing plates 49 are in a horizontal state, so as to facilitate the next bending deformation of the magnesium alloy plate.

[0054] In a bending device for manufacturing magnesium alloys according to the present invention, a stamping assembly is provided. By the up-and-down movement of the moving block 21 in the through hole 18 in the stamping assembly and the rotation of two first rotating plates 22, the angle between the two stamping plates 16 can be adjusted, so that the angle between the two stamping plates 16 can be quickly adjusted according to the required stamping angle. Further, by the upper plane contact between the upper parts of a number of first elastic bumps 24 and the lower parts of a number of second elastic bumps 25 and the inclined plane contact between the lower parts of a number of first elastic bumps 24 and the upper parts of a number of second elastic bumps 25, the moving block 21 can move upward smoothly, and the downward movement of the moving block 21 is restricted, avoiding the situation that the two stamping plates 16 rotate inward during the stamping of the magnesium alloy plate. Finally, after the water bag 26 is filled with the solution, it plays a supporting role between the two stamping plates 16, further avoiding the situation that the two stamping plates 16 rotate inward during the stamping of the magnesium alloy plate.

[0055] In a bending device for manufacturing magnesium alloys according to the present invention, by the extrusion of two stamping plates 16 in the stamping assembly and the rotation of two first placing plates 32 and a second placing plate 49 in the clamping assembly, the stamping and bending of the magnesium alloy plate can be carried out. Further, by the rotation of two second placing plates 49 in the clamping assembly to support the lower side of the magnesium alloy plate in a bent shape and the stamping of the upper side of the magnesium alloy plate in a bent shape by two stamping plates 16 in the stamping assembly, the magnesium alloy plate can be bent and deformed with high precision, improving the bending quality of the magnesium alloy plate.

[0056] The above embodiments are only used to illustrate the technical concept and features of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
