[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet material to a deformation force in the die and deform it, thereby obtaining product parts of a certain shape, size and performance.

[0003] The prior art with application number CN201711340755.6 discloses a metal product stamping machine and processing method, and the article proposes "including a workbench, a pillar is installed at the bottom of the workbench, a support frame is installed on the top of the workbench, a support plate is arranged on the top of the support frame, a stamping platform is opened on the workbench, a limiting block is arranged on the front end surface of the stamping platform, a movable plate is arranged on the top of the inner cavity of the support frame, two groups of fixed blocks are arranged on the top of the support plate, two groups of hydraulic telescopic rods are arranged on the bottom of the support plate, two groups of sleeves are sleeved on the outer wall of the movable plate, and the hydraulic telescopic rods are connected to the sleeves, and a shock-absorbing plate is installed on the bottom of the sleeve".

[0007] Furthermore, the limit assembly, limit plate, support rod, return spring, limit block and rubber block, the top two ends of the fixing groove are provided with limit plates, and the two ends of the limit plate are plugged with support rods, the bottom end of the support rod is welded and fixed to the top end surface of the stamping table, the support rod is sleeved with a return spring, and the top end of the return spring is fitted with the bottom end surface of the limit plate, the top end of the support rod is threadedly installed with a limit block, and the limit block is located above the top of the limit plate, and the bottom end surface of the limit plate is screwed with a rubber block.

[0008] Furthermore, the bottom of the rubber block is corrugated, and a protective pad is glued to the top end surface of the limiting plate.

[0009] Furthermore, a connecting block is welded to the top of the inner wall of the fixing frame, and a second mold is screwed to the bottom of the connecting block, the outer contour of the second mold and the inner contour size and shape of the first mold are the same, screw rods are threadedly installed on both sides of the fixing frame, and an anti-sliding block is sleeved on one end of the screw rod, and the outer wall of the anti-sliding block is in contact with the outer wall of the second mold.

[0010] Furthermore, a liquid storage barrel is screwed on one side of the punching table, and a diversion pump is provided on the top of the liquid storage barrel.

[0011] Furthermore, an electric box is screwed to the other side of the top of the punching table, and a controller is screwed to the electric box, and a display screen is screwed to the top of the electric box.

[0012] Furthermore, a guide block is screwed on the outer wall of the punching table, and a bracket is welded on the guide block, a conveyor is screwed on the bracket, and pads are welded on the outside of both ends of the fixed groove, and the top of the pad is flush with the top of the first mold.

[0013] Furthermore, a support is screwed to the outer wall of the punching table, and the other end of the support is screwed and fixed to the bottom end surface of the bracket, and side plates are welded to both sides of the bracket.

[0014] A stamping method suitable for a stamping die for automated metal product processing comprises the following steps:

[0015] S1: Material filling, by pouring the release agent into the liquid storage barrel, screwing the first mold into the fixed groove, plugging the second mold into the connecting block, turning the screw rod, so that the anti-sliding block can clamp the second mold, improve the stability of the second mold, and then reinforce the second mold by screwing, extracting the release agent through the diversion pump, and then conveying the release agent to the atomizing nozzle through the conveying pipe. The release agent can be sprayed into the first mold by the atomizing nozzle, and the metal plate is placed on the conveyor, and the metal plate is conveyed to the first mold by the conveyor;

[0016] S2: Die stamping: The fixed frame is pushed down by the hydraulic cylinder, so that the second die can stamp the metal plate, and the metal plate is sunk into the first die to complete the stamping. During the downward movement of the fixed frame, the transmission rod will move synchronously. The transmission rod is used to drive the first pressing plate to move downward, and the transmission plate can be pressed to make the spring telescopic rod come out of the through hole and retract into the fixed groove. The connecting plate can be used to drive the second pressing plate to move downward synchronously. The second pressing plate presses the limit plate to move the rubber block downward and press the fixed metal plate to prevent the metal plate from moving during the stamping process, which affects the stamping effect.

[0017] S3: Take out the mold. When the stamping is finished, the hydraulic cylinder drives the fixed frame to move up. Since the transmission rod is connected to the fixed frame, when the fixed frame moves up, the first pressure plate will move up synchronously. The spring telescopic rod that loses pressure will re-extend and pass through the through hole to lift the stamping part in the second mold. The staff can remove the stamping part, and the second pressure plate will simultaneously lose the squeezing effect on the limit plate. Under the reset action of the reset spring, the limit plate will be lifted to separate the rubber block from the metal plate, making it easier for the conveyor to drive the metal plate to continue to move forward for secondary stamping.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The fixed frame is pushed down by the hydraulic cylinder. During the downward movement of the fixed frame, the transmission rod will move synchronously. The transmission rod is used to drive the first pressure plate to move down, and the transmission plate can be pressed to make the spring telescopic rod come out of the through hole and retract into the fixed groove. The second pressure plate can be driven to move down synchronously by the connecting plate. The second pressure plate presses the limit plate to move the rubber block down and press the fixed metal plate to prevent the metal plate from moving or tilting during the stamping process, affecting the stamping effect. After the stamping is completed, the hydraulic cylinder drives the fixed frame to move up. Since the transmission rod is connected to the fixed frame, when the fixed frame moves up, the first pressure plate will move up synchronously, and the spring telescopic rod that loses pressure will re-extend and pass through the through hole to lift the stamping parts in the second mold, which is convenient for the staff to take. In this process, the staff only needs to take the stamping parts after stamping. The degree of automation is high, which is conducive to improving work efficiency.

[0020] 2. The release agent is extracted through the diversion pump, and then transported to the atomizing nozzle through the delivery pipe. The atomizing nozzle can be used to spray the release agent into the first mold, which can prevent the stamping parts and the mold from being stuck together after stamping, making it easier to demold. The protective pad can play a buffering and protective role when the second pressing plate presses the limit plate. The support can improve the stability of the bracket, thereby reducing the vibration generated during the operation of the conveyor. The metal plate on the conveyor can be guided to the stamping table through the guide block. The pad can make the heights of both sides of the second mold consistent, ensuring that the metal plate is horizontal and the stamping effect. By turning the twist rod, the anti-sliding block can clamp the second mold to improve the stability of the second mold. The first mold and the second mold are both screwed and fixed, which makes it easy to replace the mold. BRIEF DESCRIPTION OF THE DRAWINGS

The transmission rod (12) can be used to drive the first pressing plate (13) to move downward, and the transmission plate (11) can be pressed to make the spring telescopic rod (10) come out from the through hole (9) and retract into the fixing groove (5). The connecting plate (14) can be used to drive the second pressing plate (15) to move downward synchronously. The second pressing plate (15) presses the limit plate (161) to move the rubber block (165) downward and press the fixed metal plate to prevent the metal plate from moving during the stamping process, thereby affecting the stamping effect; S3: The mold is taken out. When the stamping is finished, the hydraulic cylinder (3) drives the fixed frame (4) to move upward. Since the transmission rod (12) is connected to the fixed frame (4), when the fixed frame (4) moves upward, the first pressing plate (13) will move upward synchronously. The spring telescopic rod (10) that loses pressure will re-extend and pass through the through hole (9) to lift up the stamping part in the second mold (19). The staff can remove the stamping part, and the second pressing plate (15) will simultaneously lose the squeezing effect on the limit plate (161). Under the reset action of the reset spring (163), the limit plate (161) will be lifted up, so that the rubber block (165) is separated from the metal plate, which makes it easier for the conveyor (31) to drive the metal plate to continue to move forward for secondary stamping.
