Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, and in particular to a bending equipment for magnesium-aluminum alloy parts. Background Technology

[0002] Magnesium-aluminum alloy is an alloy composed of magnesium and aluminum, and may also contain small amounts of other metallic elements such as manganese and zinc. Magnesium-aluminum alloy has high strength and rigidity, enabling it to withstand large loads and making it suitable for manufacturing parts with high strength requirements. Magnesium-aluminum alloy parts require bending operations during the manufacturing process.

[0003] A search revealed Chinese Patent Publication No. CN219924216U, which discloses a high-temperature alloy steel bending machine with a fixed function. The machine includes a worktable with a bending block on its top surface, a stamping structure on the front side of the bending block, and a rocker arm locking clamp on the middle side. In this design, the cylinder mounting base for the stamping structure and the mounting base for the rocker arm locking clamp are rigidly connected, making it impossible to adapt to the thickness or length of the alloy parts being processed. This results in the equipment being difficult to flexibly match the needs of different workpiece specifications during actual production, limiting its applicability and failing to meet actual usage requirements. Therefore, a bending machine for magnesium-aluminum alloy parts is proposed to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bending device for magnesium-aluminum alloy parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bending device for magnesium-aluminum alloy parts includes a processing table, a plurality of support legs at the bottom of the processing table, an installation groove at the top of the processing table, a bending positioning seat at the top of the processing table, a stamping mechanism extending into the installation groove and to its top at the outer side of the processing table, an adjustment mechanism extending outward at the inner side of the bending positioning seat, and clamping components at both the adjustment mechanism and the top of the processing table.

[0007] The stamping mechanism includes a first motor, which is fixedly installed on the left side of the processing table. The output shaft of the first motor is fixedly connected to a first screw extending into the mounting groove. A movable block extending to the top of the mounting groove is threaded onto the outer side of the first screw. A support block is fixedly installed on the top of the movable block. A push cylinder extending through to the front side of the support block is fixedly installed on the rear side of the support block. A stamping block extending to the side of the bending positioning seat is fixedly connected to the output end of the push cylinder.

[0008] Preferably, the adjusting mechanism includes a second screw, which is rotatably mounted on the inner side of the bending positioning seat. A second motor is fixedly mounted on the right side of the bending positioning seat. The output shaft of the second motor is fixedly connected to the second screw. A threaded block that fits against the inner wall of the bending positioning seat is threaded on the outer side of the second screw. A mounting plate that extends through to the rear side of the threaded block is fixedly mounted on the rear side of the bending positioning seat.

[0009] Preferably, the clamping assembly includes a fixing plate, and there are two fixing plates, which are respectively fixedly installed on the top of the mounting plate and the processing table. A threaded post is threaded through the front side of the fixing plate and threaded post is threadedly installed on the rear side. A handwheel is fixedly installed on the rear side of the threaded post and a clamping plate is movably installed on the front side of the threaded post.

[0010] Preferably, a heating rod located at the bending corner is fixedly installed inside the bending positioning seat, and a bearing plate is fixedly installed on the rear side of the bending positioning seat.

[0011] Preferably, the bending positioning seat has a U-shaped structure design, and the bottom of the bending positioning seat has an elongated hole that matches the moving trajectory of the mounting plate.

[0012] Preferably, an anti-slip pad is fixedly installed on the front side of the clamping plate, and the anti-slip pad is a rubber product.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The bending equipment for the magnesium-aluminum alloy parts, by setting a first motor in the stamping mechanism to drive the first screw to rotate, can drive the moving block to move linearly along the mounting groove, thereby adjusting the position of the support block, the push cylinder and the stamping block, so that the stamping block can be adjusted according to the thickness of the alloy sheet, adapting to the bending requirements of sheets of different thicknesses.

[0015] 2. The bending equipment for this magnesium-aluminum alloy part uses a second motor in the adjustment mechanism to drive the second screw to rotate, causing the threaded block to move the mounting plate along the elongated hole of the bending positioning seat. This allows the clamping assembly on the left side to be adjusted appropriately according to the length of the alloy part. In conjunction with the threaded post and handwheel in the clamping assembly on the top of the processing table, the clamping position of the clamping plate can be manually adjusted. The rubber anti-slip pad increases the friction with the workpiece and avoids hard contact that could scratch the surface, adapting to the clamping requirements of magnesium-aluminum alloy parts of different sizes.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a bending device for magnesium-aluminum alloy parts, including a processing table 1, which serves as the main load-bearing platform of the device. Several support legs 2 are fixedly installed at the bottom of the processing table 1. The support legs 2 distribute the weight of the device through multi-point support, thereby enhancing the load-bearing capacity and stability of the processing table. An installation groove 3 is provided on the top of the processing table 1. A bending positioning seat 4 is fixedly installed on the top of the processing table 1. The bending positioning seat 4 has a U-shaped structure design. A heating rod 41 located at the bending corner is fixedly installed inside the bending positioning seat 4. It is embedded in the corner contact area to locally heat the bending part, thereby reducing the hardness and yield strength of the magnesium-aluminum alloy. The heating rod 41 adopts the components used in existing molds. A bearing plate 42 is fixedly installed on the rear side of the bending positioning seat 4. The bearing plate 42 is used to support the workpiece of the processing sheet.

[0026] A stamping mechanism 5 is fixedly installed on the outer side of the processing table 1, extending into and to the top of the mounting groove 3. The stamping mechanism 5 includes a first motor 51, which is fixedly installed on the left side of the processing table 1. The output shaft of the first motor 51 is fixedly connected to a first screw 52 extending into the mounting groove 3. A moving block 53 extending to the top of the mounting groove 3 is threaded onto the outer side of the first screw 52. A support block 54 is fixedly installed on the top of the moving block 53. A push cylinder 55 extending through to the front of the support block 54 is fixedly installed on the rear side of the support block 54. The output end of cylinder 55 is fixedly connected to a stamping block 56 extending to the side of the bending positioning seat 4. The push cylinder 55 and the stamping block 56 adopt the existing technology structure, which is designed to improve the bending effect. The bending equipment for magnesium-aluminum alloy parts can drive the first screw 52 to rotate by the first motor 51 in the stamping mechanism 5, which can drive the moving block 53 to move linearly along the mounting groove 3, thereby adjusting the position of the support block 54, the push cylinder 55 and the stamping block 56, so that the stamping block 56 can be adjusted according to the thickness of the alloy sheet, adapting to the bending requirements of sheets of different thicknesses.

[0027] An adjustment mechanism 6 extending to the outside is movably installed on the inner side of the bending positioning seat 4. The adjustment mechanism 6 includes a second screw 61, which is rotatably installed on the inner side of the bending positioning seat 4. A second motor 62 is fixedly installed on the right side of the bending positioning seat 4. The output shaft of the second motor 62 is fixedly connected to the second screw 61. A threaded block 63 that fits against the inner wall of the bending positioning seat 4 is threaded on the outer side of the second screw 61. A mounting plate 64 that penetrates to the rear side of the bending positioning seat 4 is fixedly installed on the rear side of the threaded block 63. An elongated hole 641 that matches the moving trajectory of the mounting plate 64 is opened at the bottom of the bending positioning seat 4. The adjustment mechanism 6 realizes flexible adjustment of the workpiece clamping range, which can be appropriately adjusted according to the length of the workpiece.

[0028] Both the adjusting mechanism 6 and the top of the processing table 1 are fixedly equipped with clamping components 7. The clamping components 7 include two fixing plates 71, which are respectively fixedly installed on the mounting plate 64 and the top of the processing table 1. A threaded post 72 is threaded through the rear side of each fixing plate 71 and extends to its front side. A handwheel 73 is fixedly installed on the rear side of the threaded post 72. A clamping plate 74 is movably installed on the front side of the threaded post 72. An anti-slip pad 741 is fixedly installed on the front side of the clamping plate 74. The anti-slip pad 741 is made of rubber and its rubber material can increase slip resistance. The bending equipment for magnesium-aluminum alloy parts has a high frictional force with the workpiece and avoids hard contact that could scratch the surface. The second motor 62 in the adjustment mechanism 6 drives the second screw 61 to rotate, which causes the threaded block 63 to move the mounting plate 64 along the elongated hole 641 of the bending positioning seat 4. This allows the clamping assembly 7 on the left side to be adjusted appropriately according to the length of the alloy part. With the cooperation of the threaded post 72 and the handwheel 73 in the clamping assembly 7 on the top of the processing table 1, the clamping position of the clamping plate 74 can be manually adjusted to meet the clamping requirements of magnesium-aluminum alloy parts of different sizes.

[0029] The working process of this utility model:

[0030] Step 1: First, place the magnesium-aluminum alloy part to be bent on the top of the bearing plate 42 on the back side of the bending positioning seat 4, and align the area to be bent with the corner of the bending positioning seat 4. At this time, start the second motor 62. The second motor 62 drives the second screw 61 to rotate. The threaded block 63 moves along the second screw 61 to the back side of the bending positioning seat 4, which drives the mounting plate 64 to move synchronously through the elongated hole 641, so that the clamping assembly 7 on the left side is adjusted according to the workpiece.

[0031] Step 2: When the processing plate is too long, it can be double-clamped and fixed by the clamping components 7 on the mounting plate 64 and the processing table 1. When the processing plate is short, it can be clamped and fixed by the clamping components 7 on the mounting plate 64. Specifically, the handwheel 73 is turned to drive the threaded column 72 to rotate. The threaded column 72 pushes the clamping plate 74 forward until the anti-slip pad 741 of the clamping plate 74 presses and clamps the workpiece on the back side of the quasi-bending positioning seat 4, thus completing the fixation of the workpiece.

[0032] Step 3: After fixing, start the stamping mechanism 5 to perform bending: the first motor 51 drives the first screw 52 to rotate, and the moving block 53 moves along the mounting groove 3 towards the bending positioning seat 4, driving the support block 54, the push cylinder 55 and the stamping block 56 to move synchronously until the stamping block 56 matches the thickness of the workpiece; at this time, the push cylinder 55 starts, and its output end pushes the stamping block 56 to the corner of the bending positioning seat 4. The bending action is completed by the cooperation of the stamping block 56 and the bending positioning seat 4. During the bending process, the heating rod 41 at the corner of the bending positioning seat 4 continuously heats the bending area, reduces the yield strength of the magnesium-aluminum alloy, reduces the springback after bending, and ensures accurate bending angle.

[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
