[0004] However, it is found in the actual use process that although the above device can protect workers through the protective cover, the position of the protective cover is not convenient to adjust, which hinders the blanking of automobile parts and the work of taking the parts after stretch-bending. In order to further optimize the protection effect of the device, a stretch-bending machine for automobile part production is proposed. Content of the Utility Model

[0005] The utility model provides a stretch-bending machine for automobile part production, which solves the problem that it is not convenient to blank and take parts under the premise of ensuring the protection effect in the related technology.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1 to 4As shown in the figure, this embodiment proposes a stretch-bending machine for the production of automotive parts, including a base 1, a protection mechanism 2, a stretch-bending mechanism 3, and a positioning mechanism 4. The protection mechanism 2 includes a reserved cavity 201 opened inside the base 1. The inner wall of the reserved cavity 201 is fixedly connected with a servo motor 202, and the output shaft end of the servo motor 202 is fixedly connected with a lead screw 203.

[0025] When the servo motor 202 starts, it drives the lead screw 203 to rotate, and the rotation of the lead screw 203 does not contact the inner wall of the reserved cavity 201.

[0026] A movable sleeve block 204 is installed in the inner wall of the reserved cavity 201. The inner wall of the sleeve block 204 is threadedly connected with the outer surface of the lead screw 203. When the lead screw 203 rotates, the sleeve block 204 moves in the inner wall of the reserved cavity 201.

[0027] The other end of the sleeve block 204 is fixedly connected with a protective cover 205. The protective cover 205 is located in front of the base 1. The upper surface of the base 1 is fixedly connected with a stretch-bending forming plate 5. The height value of the protective cover 205 is greater than the height value of the stretch-bending forming plate 5. By limiting the height of the protective cover 205, more comprehensive protection can be provided for the staff during the stretch-bending process.

[0028] When the sleeve block 204 moves, it drives the protective cover 205 to move, so that the protective cover 205 can approach or move away from the base 1.

[0029] When performing the stretch-bending work on automotive parts, the protective cover 205 can be made to approach the base 1 and contact the surface of the base 1, so as to provide protection for the workers in front of the base 1 and avoid sudden breakage and outward ejection due to accidental factors during stretch-bending, which may injure the operating workers.

[0030] After the stretch-bending work is completed, the protective cover 205 can be made to move away from the base 1, so as to facilitate the removal of the automotive parts that have completed the stretch-bending work above the base 1, realizing more convenient blanking and material taking work.

[0031] Mounting seats 6 are fixedly connected to the four corners of the bottom surface of the base 1. By setting the mounting seats 6, the device can be conveniently positioned at a suitable position to perform the stretch-bending work on automotive parts.

[0032] Embodiment 2

[0033] As Figures 1 to 4As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment further proposes that the stretch-bending mechanism 3 includes guide rails 301 fixedly connected to both sides of the base 1. The inner wall of each guide rail 301 is fixedly connected with a hydraulic rod 302. The output ends of the two hydraulic rods 302 are both fixedly connected with connection blocks 303, and the two connection blocks 303 are respectively slidably sleeved in the inner walls of the two guide rails 301.

[0034] By setting the hydraulic rod 302, when the hydraulic rod 302 is started, the corresponding connection block 303 can be moved in the inner wall of the guide rail 301.

[0035] A synchronous controller 304 is installed behind the base 1. The two hydraulic rods 302 are both electrically connected to the synchronous controller 304. By setting the synchronous controller 304, the two hydraulic rods 302 can be controlled to work synchronously, thereby facilitating the stretch-bending work of automotive parts.

[0036] Both sides of the base 1 are rotatably connected with support arms 305. The outer surface of each support arm 305 is hinged with a connecting rod 306 through a pin shaft. The mutually approaching ends of the two connecting rods 306 are respectively hinged to the two connection blocks 303. By setting the connecting rod 306, the connection block 303 can drive the support arm 305 to rotate during the movement, which is beneficial to the subsequent stretch-bending work.

[0037] When the two hydraulic rods 302 are started to work, the two connection blocks 303 can be moved in the corresponding guide rails 301, thereby being able to adjust the positions of the two support arms 305 and facilitating the subsequent stretch-bending work.

[0038] The upper surface of each support arm 305 is fixedly connected with a fixing plate 307. One side surface of the two fixing plates 307 that approaches each other is fixedly connected with a cylinder 308. Receiving grooves 309 are opened on both sides of the base 1, and the receiving grooves 309 are adapted to the fixing plates 307. By setting the receiving grooves 309, the fixing plates 307 can be received when the support arms 305 rotate, preventing the occurrence of movement interference during the stretch-bending of automotive parts.

[0039] The positioning mechanism 4 includes two positioning grooves 401. The mutually remote side surfaces of the two positioning grooves 401 are respectively fixedly connected to the output ends of the two cylinders 308. By setting the positioning grooves 401, the positioning work of automotive parts can be facilitated.

[0040] A bolt 402 is threadedly connected to the inner wall of each positioning groove 401. The two ends of each bolt 402 are respectively fixedly connected with a positioning piece 403 and a hexagonal head 404. By setting the positioning piece 403, the automotive part can be conveniently positioned in the inner wall of the positioning groove 401, facilitating the subsequent stretch-bending work. By setting the hexagonal head 404, the contact area on the outer surface of the bolt 402 can be increased, facilitating the rotation of the bolt 402.

[0041] After positioning both ends of the automotive part in the two positioning grooves 401 respectively, the two hydraulic rods 302 can be driven to work synchronously, so that the two support arms 305 rotate simultaneously, and then the automotive part above the base 1 can be bent by the bending forming plate 5.

[0042] Working principle: When bending the automotive part, the servo motor 202 can be driven to work first to make the lead screw 203 rotate. By the rotation of the lead screw 203, the sleeve block 204 can move along the reserved cavity 201, and then the protective cover 205 can be moved away from the front of the base 1 through the movement of the sleeve block 204, so that the automotive part can be conveniently positioned above the base 1. When positioning the automotive part, its two ends can be respectively placed in the two positioning grooves 401. During the placement process, the position of the positioning groove 401 can be adjusted by the air cylinder 308, and then the bolt 402 can be rotated by turning the hexagonal head 404 with a wrench, and then the automotive part can be positioned in the positioning groove 401 through the positioning piece 403. Then, the servo motor 202 is driven to make the lead screw 203 rotate in the reverse direction. By the reverse rotation of the lead screw 203, the sleeve block 204 drives the protective cover 205 to move close to the front of the base 1 until the protective cover 205 contacts the surface of the base 1. Then, the two hydraulic rods 302 are started to make the two connecting blocks 303 move synchronously, and the two support arms 305 are made to rotate synchronously through the two connecting rods 306. In this way, the automotive part clamped in the two positioning grooves 401 can be bent by the bending forming plate 5. During the bending process, the protective cover 205 can provide protection for the staff in front of the base 1 to avoid sudden fracture due to accidental factors during bending and flying outwards to injure the operating workers. When the bending work is completed, the servo motor 202 can be started again to make the protective cover 205 move away from the base 1, which is convenient for removing the bent automotive part.

[0043] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
