Description

Technical Field

[0001] The present application belongs to the field of stamping die technology, and in particular relates to an automated stamping die. Background Art

[0002] A stamping die is a special tool used in stamping processing to process metal or other materials into parts of specific shapes and sizes. It is mainly composed of an upper die, a lower die, a punch, a die, guide pins and guide sleeves. During the automated stamping process using a stamping die, the material is first placed on the die, and then the upper die is pressed downward with the movement of the slider. The punch and die work together to extrude the material into the required shape and size. After the stamping is completed, the part is removed from the die, completing a stamping cycle.

[0003] The existing utility model with authorization announcement number CN213079743U discloses an automated stamping die, which drives the screw fixedly connected to it to rotate through the rotation of the motor. The rotation of the screw enables the support rod threadedly connected to it to move up and down on the screw. The coordinated use of the two support rods drives the stamping block to move in the stamping block groove. The length of the stamping block exposed to the outside can be changed, which makes it convenient for users to adjust the die according to needs so that the die can be used to produce products with different groove depths.

[0004] Although the above technical solution can produce products with different groove depths, the stamping structure of the above technical solution can only be adjusted but not replaced. The stamping structure is difficult to replace after wear or damage during actual use. There is a lack of a convenient disassembly and assembly structure for replacing important stamping structures, which makes it inconvenient to replace the stamping structure after wear or damage, affecting subsequent maintenance costs.

[0005] To this end, we proposed an automated stamping die to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that there is a lack of a convenient disassembly and assembly structure for replacing important stamping structures, which makes it inconvenient to replace the stamping structure after wear or damage, affecting subsequent maintenance costs, and to propose an automated stamping die.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] The cam is fixedly provided with a pressing plate and a lower plate, and the upper plate is fixedly provided with a pressing plate and a lower plate. The upper surface of the lower plate is fixedly connected with four guide pillars, the bottom surface of the lower plate is fixedly connected with four guide sleeves, the upper surface of the pressing plate is fixedly connected with four sliding pillars, the outer surface of each sliding pillar is sleeved with a return spring, the bottom surface of the recessed plate is fixedly connected with two limiting pillars, the bottom end of each limiting pillar is fixedly connected with a magnetic suction disk, the inner bottom wall of the lower plate is fixedly connected with two magnetic disks, the bottom surface of the upper plate is fixedly connected with a top pillar, the interior of the top pillar is clamped with a stamping block, the inner wall of the top pillar is fixedly connected with a magnetic plate, and the inner wall of the stamping block is fixedly connected with a magnetic suction plate.

[0009] Preferably, the interior of each guide sleeve is slidably connected to the outer surface of the guide column, the outer surface of each sliding column is slidably connected to the interior of the upper mold, the two ends of each return spring are respectively in contact with the bottom surface of the upper mold and the upper surface of the pressure plate, the outer surface of each limit column is in contact with the inner wall of the lower mold, the upper surface of each magnetic disk is in contact with the bottom surface of the magnetic suction cup, the outer surface of the top column and the outer surface of the stamping block are slidably connected to the interior of the pressure plate, the back side of the magnetic suction plate is in contact with the front side of the magnetic plate, and the two side surfaces of the lower mold are fixedly connected with mounting plates, and the upper surface of each mounting plate is provided with a number of identical mounting holes.

[0010] Preferably, the front side and the back side of the concave mold are both fixedly connected with supporting plates, and the outer surface of each supporting plate is fixedly connected with an anti-slip sleeve.

[0011] Preferably, a connecting block is provided above the upper die, and the inner wall of the connecting block and the inner wall of the upper die are threadedly connected with four fastening bolts.

[0012] Preferably, a washer is sleeved on the outer surface of each fastening bolt, and the bottom surface of each washer is in contact with the outer surface of the connecting block.

[0013] Preferably, a docking plate is fixedly connected to the upper surface of the connecting block, and a plurality of identical docking holes are opened on the upper surface of the docking plate.

[0014] In summary, the technical effects and advantages of this application are:

[0015] Through the mutual cooperation of the lower die, upper die, guide pillar, guide sleeve, sliding pillar, return spring, pressure plate, die, limit pillar, magnetic suction cup, magnetic disk, top pillar, stamping block, magnetic plate and magnetic plate, the lower die and upper die are relatively close or far away with the assistance of the guide pillar and guide sleeve, so that the stamping block can stamp the product placed on the die, and the magnetic suction cup can be magnetically attracted to the magnetic disk, and the magnetic plate can be magnetically attracted to the magnetic plate. Therefore, when the die or stamping block needs to be replaced, it is only necessary to pull up the die with a little force and then replace it, or pull out the stamping block with a little force from the top pillar and then replace it. This makes it convenient to replace the die and stamping block which play an important role in stamping, and greatly reduces the subsequent maintenance cost of the stamping die, and avoids the problem that the stamping structure is inconvenient to replace after wear or damage due to the lack of a convenient disassembly and assembly structure for easy replacement of important stamping structures, thereby affecting the subsequent maintenance cost.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-8 , an automated stamping die, including a lower die 1, a concave die 8, a pressing plate 7 and an upper die 2 are respectively arranged above the lower die 1, four guide pillars 3 are fixedly connected to the upper surface of the lower die 1, and four guide sleeves 4 are fixedly connected to the bottom surface of the lower die 1, the interior of each guide sleeve 4 is slidably connected to the outer surface of the guide pillar 3, and the two side surfaces of the lower die 1 are fixedly connected with mounting plates 16, and the upper surface of each mounting plate 16 is provided with a number of identical mounting holes 17. By setting the mounting holes 17, the mounting plates 16 can be fixed with external bolts to fix the position of the lower die 1, thereby fixing the position of the lower die 1, thereby increasing the stability of the lower die 1 when in use.

[0027] Four sliding columns 5 are fixedly connected to the upper surface of the pressure plate 7, and the outer surface of each sliding column 5 is sleeved with a return spring 6. The bottom surface of the die 8 is fixedly connected to two limit columns 9. The outer surface of each sliding column 5 is slidably connected to the inner part of the upper die 2. The two ends of each return spring 6 are respectively in contact with the bottom surface of the upper die 2 and the upper surface of the pressure plate 7. The outer surface of each limit column 9 is in contact with the inner wall of the lower die 1. The front and back sides of the die 8 are fixedly connected with a support plate 18. The outer surface of each support plate 18 is fixedly connected with an anti-slip sleeve 19. By providing the support plate 18, it is convenient to lift the die 8 away from the lower die 1 after holding it by hand, thereby facilitating the disassembly and assembly of the die 8. By providing the anti-slip sleeve 19, the anti-slip property of the outer surface of the support plate 18 can be increased.

[0028] The bottom end of each limiting column 9 is fixedly connected to a magnetic suction cup 10, and the inner bottom wall of the lower mold 1 is fixedly connected to two magnetic disks 11. The upper surface of each magnetic disk 11 is in contact with the bottom surface of the magnetic suction cup 10. A connecting block 20 is provided above the upper mold 2. The inner wall of the connecting block 20 and the inner wall of the upper mold 2 are commonly threadedly connected with four fastening bolts 21. By providing the fastening bolts 21, the connecting block 20 can be fixedly installed above the upper mold 2, thereby facilitating the docking of the connecting block 20 with the external stamping power mechanism.

[0029] The bottom surface of the upper mold 2 is fixedly connected to the top column 12, and the inside of the top column 12 is clamped with a stamping block 13. The outer surface of the top column 12 and the outer surface of the stamping block 13 are both slidably connected to the inside of the pressure plate 7. The outer surface of each fastening bolt 21 is sleeved with a washer 22, and the bottom surface of each washer 22 is in contact with the outer surface of the connecting block 20. By providing the washer 22, it can be padded between the connecting block 20 and the fastening bolt 21 and increase the contact area between the two, thereby increasing the fastening effect of the fastening bolt 21.

[0030] The inner wall of the top column 12 is fixedly connected with a magnetic plate 14, the inner wall of the stamping block 13 is fixedly connected with a magnetic plate 15, the back of the magnetic plate 15 is in contact with the front of the magnetic plate 14, and the upper surface of the connecting block 20 is fixedly connected with a docking plate 23. The upper surface of the docking plate 23 is provided with a number of identical docking holes 24. By setting the docking holes 24, the docking plate 23 can be docked with the external stamping power mechanism in conjunction with external bolts, thereby facilitating the external stamping power mechanism to drive the upper mold 2 to rise and fall.

[0031] The working principle of the present invention is as follows: when in use, the docking hole 24 is used to cooperate with the external bolt to fix the docking plate 23 with the external stamping power mechanism, and on the basis of ensuring the relative stable sliding of the guide column 3 and the guide sleeve 4, the mounting hole 17 is used to cooperate with the external fixing bolt to fix the mounting plate 16 under the upper die 2. Then, when stamping is required, the product to be stamped is placed on the die 8, and the external stamping mechanism is used to drive the upper die 2 to move up and down to realize the stamping process of the product to be stamped. Since the magnetic suction disk 10 can be magnetically attracted to the magnetic disk 11, and the magnetic plate 14 can be magnetically attracted to the magnetic plate 15, When the die 8 or the punching block 13 is severely worn or damaged and needs to be replaced, you only need to overcome the corresponding magnetic force, hold the support plate 18 with your hand, pull the die 8 up with a little force, and then replace it, or pull the punching block 13 out of the top column 12 with a little force, and then replace it. This makes it convenient to replace the die 8 and the punching block 13 that play an important role in stamping, which greatly reduces the subsequent maintenance cost of the stamping die. The design of the entire automated stamping die effectively solves the problem of the lack of a convenient disassembly and assembly structure for facilitating the replacement of important stamping structures, which makes it inconvenient to replace the stamping structure after wear or damage, affecting the subsequent maintenance cost.
