Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, and in particular to a bending component for automotive mold processing. Background Technology

[0002] Patent document CN222428954U discloses a novel multi-bending structure, including a base plate. A frame is fixedly connected to both ends of the top of the base plate. Hydraulic cylinders are fixedly installed in the middle of both sides of the top of the frame. Mounting plates are fixedly connected to the bottom ends of the two hydraulic cylinders. Several insertion slots are opened at the bottom of the mounting plates. A bending knife is inserted into the inner wall of one of the insertion slots. Slide rails are fixedly connected to both sides of the top of the base plate. Sliding strips are slidably connected to the surfaces of the two slide rails. A placement platform is fixedly connected to the surface of the two sliding strips. An installation cavity is opened at the top inside the placement platform.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0046] Example 1

[0047] like Figure 1-10 As shown, this utility model proposes a bending assembly for automotive mold processing, including a frame 100, and further including a bending bearing member, a reset member, a limiting member, a bending member, and a fixing member. The bending bearing member has an assembly space on its upper part. The reset member is disposed in the bending bearing member. The limiting member is disposed in the bending bearing member, with one side of the limiting member contacting the reset member. The limiting member can move under the drive of the reset member. The bending member is disposed in the bending bearing member, with one side of the bending bearing member contacting the limiting member. The bending member bends the sheet metal. The fixing member is disposed in the bending bearing member, with one side of the fixing member abutting against the bending member. The fixing member fixes the bending member.

[0048] In this embodiment, the bending load-bearing component includes a fixed support 110 and a sliding circular groove 120. The fixed support is rectangular in shape. The top of the fixed support is provided with a threaded hole 111, a first threaded hole 112, and a second threaded hole 113. The upper part of the fixed support is provided with an inner square groove 114. The fixed support is provided with a guide rail 115. There is a pair of sliding circular grooves. The sliding circular grooves are formed in the fixed support. One side of the sliding circular groove is connected to the inner square groove of the fixed support, and the other side of the sliding circular groove is connected to the guide rail.

[0049] In this embodiment, the reset component includes a limiting plate 210, a connecting bolt 220, a spring guide pin 230, and a reset spring 240. The limiting plate is disposed in the concave square groove of the fixed support. The limiting plate is provided with a threaded hole 211 corresponding to the threaded hole 1. The connecting bolt is inserted into the threaded hole 211 and the threaded hole 1 in sequence, and forms a threaded engagement with the threaded hole 211 and the threaded hole 1. The connecting bolt limits the limiting plate. The spring guide pin is disposed in the sliding circular groove, and one side of the spring guide pin abuts against the limiting plate. The reset spring is sleeved on the spring guide pin, and one side of the reset spring abuts against the limiting plate.

[0050] In this embodiment, the limiting component includes a top pin 310, which is disposed in a sliding circular groove. One side of the top pin abuts against one side of the return spring, and one side of the top pin extends out of the sliding circular groove. The front end of the top pin is provided with an arc portion, and the top pin is provided with an insertion hole.

[0051] In this embodiment, the bending component includes a bending roller 410 and a limiting groove 420. The bending roller is mounted on a guide rail of a fixed support. The bending roller has a bending part 411, which contacts the sheet metal to bend it. The limiting groove is formed on the bending roller and has an abutment surface 421 and a guide surface 422. The limiting groove contacts a top pin, and the top pin cooperates with the limiting groove to limit the bending roller. The abutment surface abuts against the top pin, so that the bending roller can only rotate clockwise. While the bending roller rotates clockwise, its bending part contacts the sheet metal, thereby driving the sheet metal to bend. The shape of the sheet metal after bending is adapted to the shape of the bending part. By controlling the angle and shape of the bending part, the bending angle of the sheet metal can be adjusted. At this time, only the shape of the bending part has a unique influence on the bending of the sheet metal. As long as the shape of the bending part remains unchanged, the bending angle of the sheet metal is always the angle adapted to the bending part, thereby ensuring the bending accuracy of the sheet metal.

[0052] In this embodiment, the fixing component includes a fixing block 510 and a connecting bolt 520. The fixing block is disposed on the top of the fixing support. The top of the fixing block is provided with a threaded hole 511. The position of the threaded hole 511 corresponds one-to-one with the position of the threaded hole 520. One side of the fixing block has a limiting part 512, which abuts against one side of the bending roller. The fixing block limits the bending roller. The connecting bolt is inserted into the threaded hole 510 and the threaded hole 511 in sequence. The connecting bolt and the threaded hole 510 form a threaded engagement, and the fixing block is fixed by the connecting bolt.

[0053] In this embodiment, a reinforcing coating is provided on the bending part of the bending roller. The reinforcing coating is a carburized layer, which increases the hardness and wear resistance of the bending part.

[0054] Example 2

[0055] like Figure 1-12 The difference between this embodiment and embodiment 1 is that, in this embodiment, the frame is provided with a sliding groove.

[0056] In this embodiment, the limiting assembly further includes a rotating screw 610, a guide rod 620, a spacer block 630, a drive cylinder 640, and a limiting block 650. The rotating screw is rotatably mounted on the bottom of the processing table, and a handwheel is provided on one side of the rotating screw. The guide rod is located on the bottom of the processing table, and the spacer block is slidably mounted in a groove of the processing table. The bottom of the spacer block and the rotating screw form a threaded engagement, and the other side of the spacer block is slidably mounted on the guide rod. The drive cylinder is mounted on the spacer block, and the limiting block is mounted on the drive end of the drive cylinder. The limiting block limits the material. During processing, by rotating the rotating screw, the rotating screw drives the spacer block to move through the threaded engagement, thereby adjusting the position of the material. Then, the material abuts against the spacer block, and at the same time, the drive cylinder drives the limiting block to fix the material, thereby completing the fixing of the material without manual fixing, and also precisely controlling the extension length of the material.

[0057] The working principle of this utility model:

[0058] When processing the sheet metal, the top pin is placed into the sliding groove of the fixed support, and the return spring is sleeved on the spring guide pin. The spring guide pin and the return spring are placed in the sliding groove, with one side of the return spring abutting against one side of the top pin. The limiting plate is then placed into the concave square groove to limit the spring guide pin and the spring. The connecting bolt is inserted into the threaded hole three of the limiting plate to fix the fixing block. At the same time, the bending roller is placed on the guide rail of the fixed support, with the limiting groove contacting the top pin. The abutting surface of the limiting groove abuts against the top pin, and the guide surface contacts the arc part of the top pin. The limiting part abuts against the bending plate. The fixing block is placed on top of the fixed support, and the fixing block limits the bending roller. The connecting bolt one is then inserted into the limiting plate. The bending roller is fixed in four threaded holes. The sheet metal is then placed on the frame. The drive unit moves the fixed support downward, and the bending part of the bending roller comes into contact with the sheet metal. The bending part rotates passively and abuts against the sheet metal, bending it. At the same time, the guide surface of the limiting groove moves the top pin toward the compression return spring. When one side of the bending part is completely in contact with the sheet metal, the fixed support can no longer move downward. At this point, the shape of the sheet metal matches the bending part, and the bending of the sheet metal is completed. The drive unit moves the fixed support upward, and the bending part of the bending roller no longer comes into contact with the sheet metal. Under the action of the return spring, the top pin pushes the limiting groove, thereby resetting the bending roller. The bending of the sheet metal is now complete.
