DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 In this embodiment, a fast sheet metal Z-shaped CNC bending forming mold includes a lower mold 1, and a sponge pad is fixed to the bottom of the lower mold 1. The sponge pad can effectively improve the stability of the lower mold 1, so that the whole is not easy to shake during bending, so that the whole is more stable. Two connecting rods 2 are fixed to the top of the lower mold 1, and a connecting plate 3 is fixed to the top of the connecting rod 2. A cylinder 4 is fixed inside the connecting plate 3. The cylinder 4 is used to push the upper mold 6 to move, so that the bending work of the workpiece can be completed. A buffer assembly 5 is fixed to the telescopic end of the cylinder 4. The buffer assembly 5 includes a support spring fixed to the telescopic end of the cylinder 4. The support spring can play a certain buffering role, so that the bending is more stable.

[0023] In addition, a connecting block is fixed at the bottom of the support spring and is slidably connected to the telescopic end of the cylinder 4. Sliding blocks are fixed on both sides of the telescopic end of the cylinder 4. A sliding groove is provided inside the connecting block and is slidably connected to the sliding block. The sliding block and the sliding groove can effectively improve the stability of the cylinder 4 sliding inside the connecting block. The connecting block is fixed to the upper mold 6, and the buffer assembly 5 is used to improve the stability during bending and forming.

[0024] Furthermore, an upper mold 6 is fixed to the bottom of the buffer component 5, and stabilizing blocks 10 are fixed on the left and right sides of the upper mold 6. The stabilizing blocks 10 are slidably connected to the connecting rod 2. The sliding connection can further improve the overall stability and make the whole more durable. Fixed components 7 are provided inside the upper mold 6 and the lower mold 1. Support blocks 8 and forming blocks 9 are respectively fixed on the opposite sides of the two fixed components 7. The provided support blocks 8 and forming blocks 9 are used to bend and shape the workpiece. Support blocks 8 and forming blocks 9 of different shapes can be replaced according to different bending specifications. The fixed components 7 are used to install support blocks 8 and forming blocks 9.

[0025] In general, when the cylinder 4 pushes the upper mold 6 to move, when the forming block 9 contacts the workpiece, the telescopic end of the cylinder 4 will slide inside the connecting block, so that the supporting spring can provide a certain buffer, thereby effectively improving the stability of the bending work and making the whole more practical.

[0026] See also Figure 2-4 The fixing assembly 7 in this embodiment includes a positioning block 701, a positioning plate 702, a fixing plate 703, a fixing block 704 and a control block 705. The two positioning blocks 701 are respectively slidably connected to the lower mold 1 and the upper mold 6. The opposite sides of the two positioning blocks 701 are respectively fixed to the two positioning plates 702. The two positioning plates 702 are respectively slidably connected to the lower mold 1 and the upper mold 6. The fixing of the positioning blocks 701 and the positioning plates 702 can effectively improve the stability of the connection. In addition, the setting of the positioning blocks 701 effectively limits the upward, downward, leftward and rightward movements of the support block 8 and the forming block 9.

[0027] In addition, the two positioning plates 702 are respectively fixed to the support block 8 and the forming block 9, the two fixing plates 703 are respectively slidably connected to the lower mold 1 and the upper mold 6, the front of the fixing plate 703 is fixed to the fixing block 704, the diameter of the control block 705 is larger than the diameter of the fixing block 704, the two fixing blocks 704 are respectively slidably connected to the lower mold 1 and the upper mold 6, the front of the fixing block 704 is fixed to the control block 705, and the outer surface of the control block 705 is fixed with a friction strip. By setting the friction strip, the comfort when controlling the control block 705 can be effectively improved, thereby making the whole more practical.

[0028] In general, the positioning block 701 and the positioning plate 702 are fixed so that the support block 8 and the forming block 9 are inserted into the lower mold 1 and the upper mold 6, thereby effectively limiting the upward, downward, left and right movements. The sliding fixing plate 703 can effectively limit the forward and backward movement of the positioning block 701. The overall structure is simple, which effectively improves the replacement efficiency and reduces the cost of replacing production of different specifications, effectively improving the overall practicality.

[0029] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0030] The working principle of the above embodiment is:

[0031] When the workpiece is placed on the top of the support block 8, the cylinder 4 can be started to push the upper mold 6 to move, so that the upper mold 6 pushes the forming block 9 to contact the workpiece and complete the bending of the workpiece. When the bending specifications need to be changed, it is only necessary to pull the control block 705 to the right so that the control block 705 can drive the fixed block 704 and the fixed plate 703 to move to the inside of the lower mold 1 and the upper mold 6, so that the positioning block 701 and the positioning plate 702 are no longer restricted. At this time, the support block 8 and the forming block 9 can be moved to the front, the support block 8 and the forming block 9 can be taken out, and the support block 8 and the forming block 9 of the corresponding specifications can be installed subsequently. The overall structure is simple, which effectively reduces the cost of changing specifications and makes the overall structure more practical.
