Technical Field

[0001] The utility model relates to the technical field of bending equipment, in particular to a CNC numerical control bending device for a mainboard bracket. Background Art

[0002] At present, CNC bending devices are used to bend the server motherboard brackets during production and processing. The CNC bending machine uses the equipped mold to bend cold metal sheets into workpieces of various geometric cross-sectional shapes. It is a sheet forming machine designed for cold rolled sheet metal processing.

[0003] In the related technology, a bending device is designed, which includes a machine body, a mold and a bending head. The mold is fixed on the machine body, and the bending head is raised and lowered on the machine body and is located directly above the mold. When bending the bracket, the worker holds the bracket and puts it into the mold, positions the bracket on the mold, and then uses the bending head to slide toward the mold. The bending head and the bracket are offset from each other to drive the bracket to deform and bend.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: in order to position the bracket to be processed, it is necessary to manually support the bracket and send the bracket into the mold. However, if the staff is distracted and does not keep their hands away from the mold when supporting the bracket, the descending bending head will cause damage to the staff, which poses certain safety hazards and needs to be improved.

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The embodiment of the present application discloses a CNC numerical control bending device for a motherboard bracket. Figure 1 The machine comprises a body 11, a mold 12, a support frame 2, and a bending head 13. The mold 12 is mounted on the body 11 by bolts, and different molds 12 can be replaced according to different bending requirements. The bending head 13 is arranged on the body 11 in a lifting manner and is located directly above the mold 12. Two support frames 2 are symmetrically arranged on the side walls of the body 11. The upper surface of the support frame 2 is flush with the upper surface of the mold 12. The support frames 2 are used to support the bracket to be processed during bending.

[0030] Reference Figure 1 and Figure 2 A group of mounting frames 3 are symmetrically arranged on the side walls of the machine body 11. The mounting frames 3 and the machine body 11 are fixed to each other, and the support frame 2 is located between the mounting frames 3. Mounting rods 31 are arranged on the mounting frames 3, and the length direction of the mounting rods 31 is arranged along the height direction of the machine body 11. Isolation frames 4 are arranged between the mounting rods 31, and the length direction of the isolation frames 4 is arranged along the length direction of the machine body 11. Reset blocks 41 are symmetrically fixedly arranged at both ends of the isolation frames 4. Reset grooves 32 are provided on the opposite surfaces of the mounting rods 31 along the length direction thereof, and the reset blocks 41 are slidably arranged in the reset grooves 32. A guide rod 5 is fixedly arranged in the reset groove 32 along the length direction thereof, and the reset block 41 is slidably arranged on the guide rod 5. A reset spring 51 is arranged in the reset groove 32, and the reset spring 51 is sleeved on the guide rod 5 and abuts against the upper surface of the reset block 41. During bending, the staff places the bracket on the support frame 2 and continuously transports it to the top of the mold 12, using the support frame 2 to support the bracket. The bracket passes between the support frame 2 and the isolation frame 4. The isolation frame 4 can block the staff's hands, preventing the staff's hands from moving directly under the bending head 13 when the staff is distracted. After the bending head 13 and the bracket above the mold 12 are offset, the bracket deformation will offset the isolation frame 4. The reset blocks 41 at both ends of the isolation frame 4 can slide on the guide rod 5. After the bent bracket is pulled out, the reset spring 51 drives the isolation frame 4 to reset. The sliding isolation frame 4 is used to block the staff's hands during feeding, thereby reducing the phenomenon of the bending head 13 injuring the staff's hands. At the same time, when bending, the rune spring drives the isolation frame 4 to offset the surface of the bracket, which can improve the stability of the workpiece to be processed.

[0031] Reference Figure 1 and Figure 2 The bottom end of the isolation frame 4 is provided with an auxiliary groove 42, within which an auxiliary roller 421 is rotatably mounted. The length of the auxiliary roller 421 is arranged along the length of the isolation frame, and the surface of the auxiliary roller 421 is covered with a rubber layer. During feeding or bending, the bracket will slide between the isolation frame 4, and the bracket and the auxiliary roller 421 will be used to abut against each other. The rotating auxiliary roller 421 helps reduce friction between the bracket and the isolation frame 4, facilitating processing. The soft texture of the rubber layer can prevent the auxiliary roller 421 from damaging the bracket, thus protecting the workpiece.

[0032] Reference Figure 2The inner wall of the auxiliary groove 42 is symmetrically provided with connecting holes 6, and a connecting bolt 61 is provided through the connecting hole 6. The end wall of the auxiliary roller 421 is provided with a connecting groove 62 for inserting the connecting bolt 61. The inner wall of the connecting groove 62 is threadedly connected to the connecting bolt 61, and the auxiliary roller 421 is rotatably connected to the inner wall of the auxiliary groove 42 via the connecting bolt 61. Rotating the connecting bolt 61 disengages the connecting bolt 61 from the connecting groove 62 and removes the connecting bolt 61 from the connecting hole 6, making it easier to disassemble and assemble the auxiliary roller 421 from the auxiliary groove 42 and to clean the auxiliary roller 421.

[0033] Reference Figure 2 The mounting frame 3 is provided with a mounting slot 7 for the mounting rod 31 to pass through. The mounting slot 7 is arranged along the height direction of the mounting frame 3. The mounting rod 31 is slidably arranged in the mounting slot 7 and is adapted to fit in the mounting slot 7. A locking bolt 71 is provided through the inner wall of the mounting slot 7. The locking bolt 71 is threadedly connected to the mounting frame 3. The side wall of the mounting rod 31 is provided with a plurality of locking holes 311 for the locking bolts 71 to be inserted and abutted against each other. The locking bolt 71 is rotated and slid between the locking bolt 71 and the mounting frame 3, so that the locking bolt 71 and the locking holes 311 are disengaged from each other. At this time, the mounting rod 31 can be driven to slide vertically in the mounting slot 7. The locking bolt 71 can then be inserted into different locking holes 311. The length of the mounting rod 31 on the mounting frame 3 can be adjusted, and the height of the isolation frame 4 can be adjusted, which facilitates the processing of motherboard brackets of different thicknesses.

[0034] Reference Figure 1 A set of sliding grooves 8 are provided on the side wall of the body 11. The length direction of the sliding grooves 8 is arranged along the length direction of the body 11. A sliding assembly 9 is provided on the body 11. The sliding assembly 9 includes a rack 91, a gear 92 and a drive rod 93. The rack 91 is slidingly set in the sliding groove 8. The length direction of the rack 91 is arranged along the length direction of the sliding groove 8. One support frame 2 is fixed to one rack 91, and the other support frame 2 is fixed to the other rack 91. A drive groove 81 is provided between the sliding grooves 8. The gear 92 is rotatably set in the drive groove 81. The gear 92 is meshed with the two racks 91 at the same time. The drive rod 93 is provided on the side wall of the gear 92. The drive rod 93 passes through the gear 92 and is threadedly connected to the gear 92. Holding the driving rod 93, the gear 92 is driven to rotate. The gear 92 is simultaneously pressed against the two racks 91, driving the racks 91 to slide in the sliding groove 8, thereby driving the two support frames 2 to slide toward each other along the length direction of the sliding groove 8, adjusting the distance between the two support frames 2, and then rotating the driving rod 93. The driving rod 93 is pressed against the bottom wall of the driving groove 81 to fix the gear 92, thereby realizing the control of the distance between the two support frames 2, facilitating the bending processing of brackets of different widths, and further improving the function and scope of application of the device.

[0035] The implementation principle of the CNC bending device for the motherboard bracket of the embodiment of the present application is as follows: when bending the motherboard bracket, the bracket is placed on the support frame 2 and continuously transported to the top of the mold 12, and the support frame 2 is used to support the bracket. When the bracket passes under the isolation frame 4, the return spring 51 drives the isolation frame 4 to abut against the upper surface of the bracket, so that when the bracket moves on the support frame 2, the isolation frame 4 can block the hands of the staff, preventing the staff from moving their hands directly under the bending head 13 when distracted; and when the bending head 13 descends to bend, The isolation frame 4 is offset against the bracket to improve the stability of the bracket. After the bending head 13 is offset against the bracket above the mold 12, the bracket will be bent under force, and the deformation of the bracket will be offset against the isolation frame 4. The reset blocks 41 at both ends of the isolation frame 4 can slide on the guide rod 5 to make way for the bracket; after bending, the bracket is pulled out, and the reset spring 51 drives the isolation frame 4 to reset; the isolation frame 4 that can slide up and down is used to block the hands of the staff during feeding, thereby reducing the phenomenon of the bending head 13 injuring the hands of the staff and improving the safety of the bending device during operation.
