The U-shaped bracket comprises two vertical parts and a horizontal part, and the two vertical parts are each provided with a circular hole, and the two circular holes are located on the same axis. The circular holes in the two vertical parts are used to pass through the two circular holes to fix the vehicle lamp on the U-shaped bracket by using a connecting piece, and the light angle of the vehicle lamp can be adjusted by the connecting piece. The horizontal part is provided with a mounting hole, and a bolt can pass through the mounting hole to fix the U-shaped bracket on the mounting seat of the vehicle body.

When the U-shaped bracket is processed, two circular holes and a mounting hole are first formed on the plate-shaped plate, and then the plate is placed on the bending equipment. The plate is bent twice by the bending equipment. Specifically, the plate is bent once, then the plate is taken down by the staff for adjustment and then bent again, so as to form the U-shaped bracket, so that the included angle between the two vertical parts and the horizontal part is ninety degrees, and the circular holes in the two vertical parts are located on the same axis. The above bending method can make the plate deform naturally during bending, so that the deformation of the material is more uniform, compared with the traditional method of clamping and fixing the plate by using a fixed device and bending the plate.

[0003] A metal material processing bending device disclosed in Chinese patent document CN112517683B is convenient to adjust, which comprises a workbench, a bending die mechanism, a tool holder mechanism, a bending tool mechanism, a main support and a fixed track are arranged at the top end of the workbench, the fixed track is located at the center position of the top end of the workbench, the main support is located on one side of the fixed track, a top plate is arranged at the top end of the main support, a hydraulic push rod is arranged at the top end of the top plate, the tool holder mechanism is located below the hydraulic push rod, and the output end of the hydraulic push rod penetrates through the bottom end of the hydraulic push rod and is connected with the tool holder mechanism.

[0004] In use, through the setting fixed track, lower module, sliding groove, limiting groove, fixed groove, bending groove, fixed hook, movable clamping block, connecting notch, pressing thread, movable hook, connecting block, fixed block, limiting sliding block and reset spring, the lower module can be quickly disassembled or installed, the lower module is connected with the fixed track through the fixed hook and the movable hook, the movable hook can be disassembled and assembled with the lower module through the fixed block and the fixed groove, the movable clamping block can fix and limit the fixed block, the fixed block can be moved out of the fixed groove by pushing the movable clamping block upwards, and then the movable hook is separated from the lower module, so that the lower module can be disassembled, and when the lower module is installed, the fixed block can be inserted into the fixed groove.

[0005] However, the above patent document still has the following shortcomings: After the plate is bent once, the worker needs to take the plate out of the bending equipment and adjust the plate before putting it into the bending equipment again for secondary bending. In the process of manual operation, the positions of the two bending of the plate are prone to deviation, so that the round holes on the two vertical parts are not on the same axis, thereby affecting the subsequent operation of installing the car lamp on the U-shaped support by passing the two round holes through the connecting piece.

DETAILED DESCRIPTION

[0037] Embodiments of the present application are described below in detail, examples of which are shown in the accompanying drawings.

The bending mechanism 1 can bend the plate 4 once and twice, so as to form a U-shaped car lamp bracket. The material containing mechanism 2 is connected to the bending mechanism 1 and is used for limiting and installing the plate 4. After the plate 4 is bent once, the material containing mechanism 2 can drive the plate 4 to overturn and move, so as to move the twice-bent part of the plate 4 to the position directly below the bending mechanism 1, so as to facilitate the bending mechanism 1 to bend the plate 4 twice, thereby forming a U-shaped car lamp bracket, and further making the round holes 44 on the bending section one 41 and the bending section two 43 located on the same axis, so as to avoid affecting the operation of installing the car lamp on the U-shaped car lamp bracket by passing the two round holes 44 through the connecting piece. The positioning mechanism 3 is connected to the material containing mechanism 2 and can be inserted into the mounting hole 45 on the plate 4, so as to position the plate 4 when it is bent once, so as to avoid deviation of the bent part of the plate 4 when it is bent once.

[0039] As shown in Figures 1 to 3 The bending mechanism 1 comprises a base 11, a gantry 12, a pushing piece 13, a mounting seat 14, a bending head 15 and a bending die 16. The gantry 12 is connected to the top of the base 11. The pushing piece 13 is connected to the inner top wall of the gantry 12 and is a pneumatic cylinder. The mounting seat 14 is connected to the telescopic end of the pushing piece 13. The bending head 15 is connected to the bottom of the mounting seat 14 and is used for bending the plate 4. The bending die 16 is arranged on the base 11 and is used for limiting the bending angle of the plate 4, so as to enable the plate 4 to be bent by ninety degrees.

[0040] The bent part of the plate 4 is placed directly below the bending head 15. The pushing piece 13 is started to drive the bending head 15 to move downward and close to the plate 4. After the bending head 15 contacts the plate 4, the plate 4 is guided by the bending die 16, so as to enable the bending section one 41 or the bending section two 43 of the plate 4 to be bent by ninety degrees and be perpendicular to the horizontal section 42. After the plate 4 is bent once and twice, a U-shaped car lamp bracket is formed.

[0041] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10As shown, the containing mechanism 2 comprises a containing seat 21, a driving member, a guide member 25, a blocking part 26 and an elastic part one 27. The containing seat 21 is limitingly and slidably connected to the top of the base 11. The top of the containing seat 21 is provided with a limiting groove 22. The limiting groove 22 can limit the plate 4 in the width direction to avoid the bending part of the plate 4 from being inclined. The bending die 16 is provided with two bending dies 16, which are both connected to the limiting groove 22 and correspond to the two bending parts of the plate 4 to facilitate one-time bending and two-time bending of the plate 4. The driving member comprises a driving source 23 and a lead screw 24. The driving source 23 is connected to the base 11 and is a motor. The lead screw 24 is connected to the output shaft of the driving source 23 and is threadedly connected to the containing seat 21. The driving source 23 drives the lead screw 24 to rotate, which can drive the containing seat 21 to move and thus drive the plate 4 after one-time bending to move to facilitate two-time bending of the plate 4. The guide member 25 is connected to the base 11. The blocking part 26 is limitingly and slidably connected to the guide member 25. The elastic part one 27 is connected between the blocking part 26 and the guide member 25 and is a compression spring for supporting the blocking part 26 and driving the blocking part 26 to reset.

[0042] The plate 4 is placed into the limiting groove 22 and the left end of the plate 4 is in contact with the left side of the inner wall of the limiting groove 22, so that the one-time bending part of the plate 4 is aligned with the bending head 15. The pushing member 13 is started to drive the bending head 15 to move downward and close to the plate 4. After the bending head 15 contacts the plate 4, the bending die 16 guides the plate 4 to be bent, so that the bending section one 41 is bent, the bending section one 41 and the horizontal section 42 are upwardly buckled, the horizontal section 42 drives the bending section two 43 to be upwardly buckled, so that the whole plate 4 is arranged in a V shape, and the bending part of the plate 4 is located in the bending die 16, thereby completing one-time bending of the plate 4.

[0043] The driving source 23 drives the screw rod 24 to rotate, and the containing seat 21 is driven by the screw rod 24 to move, so that the bending segment two 43 of the plate 4 moves to the position directly below the bending head 15. After the bending segment one 41 of the plate 4 contacts the blocking part 26, the blocking part 26 is supported by the elastic part one 27, the bending segment one 41 is blocked by the blocking part 26, so that the bending part of the plate 4 is separated from the corresponding bending die 16. At this time, the sum of the weight of the horizontal segment 42 and the bending segment two 43 is greater than the weight of the bending segment one 41, so that the plate 4 is turned over under the gravity of the horizontal segment 42 and the bending segment two 43 until the horizontal segment 42 and the bending segment two 43 are turned over to the horizontal state or are attached to the inner bottom wall of the limiting groove 22. The containing seat 21 continues to move, and the plate 4 stops moving under the blocking of the blocking part 26. After the right end of the bending segment two 43 contacts the right side of the inner wall of the limiting groove 22, the secondary bending part of the plate 4 is aligned with the other bending die 16. At this time, the right end of the bending segment two 43 is blocked, and the bending segment two 43 is driven by the containing seat 21 to move towards the position directly below the bending head 15 until the secondary bending part of the plate 4 is located directly below the bending head 15, and the plate 4 drives the blocking part 26 to move on the guide 25 and compresses the elastic part one 27. Finally, the pushing part 13 is started to drive the bending head 15 to move downward and close to the plate 4. After the bending head 15 contacts the plate 4, the plate 4 is guided by the other bending die 16, so that the bending segment two 43 of the plate 4 is bent, thereby forming a U-shaped lamp bracket. The plate 4 does not need to be manually adjusted for secondary bending, avoiding the deviation of the bending part, the round holes 44 on the bending segment one 41 and the bending segment two 43 not being on the same axis, and thereby avoiding affecting the subsequent operation of installing the lamp on the U-shaped lamp bracket through the connecting part.

The positioning part can pass through the mounting hole 45 to position the plate 4, so as to ensure that the left end of the bending segment one 41 contacts the left end of the inner wall of the limiting groove 22, thereby avoiding the deviation of the plate 4 during the first bending, enhancing the accuracy of the plate 4 during the first bending. The driving part can drive the positioning part to move downward and separate from the mounting hole 45, so as to avoid the blocking of the positioning part to the movement of the plate 4 in the limiting groove 22, so as to facilitate the secondary bending of the plate 4. The locking part 36 can lock the positioning part, and the automatic telescopic part 37 can drive the locking part 36 to move, so as to release the locking of the positioning part by the locking part 36, so as to facilitate the positioning of the next plate 4 after the positioning part resets.
