Technical Field

[0001] The invention belongs to the technical field of metal stamping dies, and in particular relates to an automatic metal stamping die. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] When the mold is stamping, the plate is placed on the molding cavity of the fixed mold, the movable mold moves downward, the molded part extends into the molding cavity, and the plate is stamped into the shape of the molding cavity. Although this can stamp the plate into shape, such a design can easily cause the already formed plate to be stuck in the molding cavity and difficult to take out. Therefore, it is very necessary to design a mold that allows the formed plate to be easily removed from the molding cavity. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic metal stamping die to solve the problems existing in the background technology.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-6 As shown, an automatic metal stamping die of the present invention comprises a machine body 1, a control box 11 is arranged outside the machine body 1, a processing area 12 is arranged in the middle of the machine body 1, a workbench 13 is arranged on the upper side of the processing area 12, a fixed die 14 is arranged on the upper side of the processing area 12, a forming cavity 15 is arranged on the upper side of the fixed die 14, a movable die 16 is slidably mounted on the upper side of the processing area 12, a forming piece 17 is arranged on the lower surface of the movable die 16, a placement groove 2 is arranged on the left and right sides of the forming cavity 15, a through hole 21 is arranged on the lower side of the two placement grooves 2, a sliding cavity 22 is arranged on the lower side of the two through holes 21, and two sliding cavities 22 are arranged on the lower side of the two through holes 21. A slider 23 is installed in the movable cavity 22 so as to slide up and down. A rebound mechanism is installed on the lower side of the two sliders 23. A slide rod 24 is rotatably installed on the upper side of the two sliders 23. A top block 25 is installed on the upper end of the two slide rods 24. A rotating mechanism matching the slide rod 24 is installed in the two sliding cavities 22. A cavity 26 is installed in the two top blocks 25. A plurality of ejection holes 27 connected to the cavity 26 are installed on the outer surfaces of the two top blocks 25. The cavity 26 is provided with a one-way discharge mechanism connected to the sliding cavity 22. The lower sides of the two sliding cavities 22 are connected together and are equipped with a one-way feeding mechanism.

[0026] When the plate needs to be stamped, the plate can be placed on the upper side of the fixed film 14 and matched with the position of the molding cavity 15. At this time, the movable mold 16 slides downward to press the molding part 17 into the molding cavity 15, and the plate can be pressed into the molding cavity 15 to stamp the plate into the shape of the molding cavity 15. When the movable mold 16 is separated from the upper side of the fixed film 14, the molded plate can be taken out of the molding cavity 15.

[0027] When not working, the extension of the rebound mechanism drives the slider 23 to move upward in the sliding cavity 22. Since the slider 23 is slidingly sealed and assembled in the sliding cavity 22, when the slider 23 moves upward in the sliding cavity 22, a negative pressure can be formed in the sliding cavity 22, and the lubricating liquid can be injected into the sliding cavity 22 through the one-way feeding mechanism. When the plate is placed on the upper side of the molding cavity 15 and the molding part 17 presses the plate downward into the molding cavity 15, the top block 25 will be pushed to move downward. The top block 25 drives the slider 23 to move downward in the sliding cavity 22 through the sliding rod 24, which can squeeze the lubricating oil in the sliding cavity 22 and squeeze the lubricating oil from the one-way discharging mechanism into the cavity 26. The lubricating oil can be discharged from the one-way discharging mechanism. The dry spray holes 27 spray outward, and the several spray holes 27 on the outer surfaces of the two top blocks 25 can spray the lubricating oil on the inner wall of the molding cavity 15, and when the slide bar 24 moves downward, under the action of the rotating mechanism, the slide bar 24 starts to rotate, and the slide bar 24 drives the top block 25 to rotate, thereby driving the several spray holes 27 to rotate, so that the lubricating oil can be rotated and sprayed evenly on the inner wall of the molding cavity 15. Such a design can reduce the friction between the plate and the inner wall of the molding cavity 15 through the lubricating oil during the process of plate forming, thereby protecting the plate and the inner wall of the molding cavity 15, and preventing the outer surface of the plate and the inner wall of the molding cavity 15 from being worn, until the top block 25 is pressed into the placement groove 2;

[0028] At the same time, when the molded part 17 is moved out of the molding cavity 15, the rebound mechanism begins to stretch, driving the slider 23 to move upward in the sliding cavity 22, and the slider 23 drives the top block 25 to move upward through the slide rod 24, which can drive the top block 25 to move upward and extend out, thereby ejecting the molded plate from the molding cavity 15, further preventing the molded plate from being stuck in the molding cavity 15, making it easier for the staff to move the molded plate out of the molding cavity 15.

[0029] The rebound mechanism includes a first spring 3 , which is assembled in the sliding cavity 22 , and the upper and lower ends of the first spring 3 are connected to the sliding block 23 and the inner wall of the sliding cavity 22 respectively.

[0030] When the top block 25 drives the slider 23 to move downward through the slide rod 24, the first spring 3 can be compressed. When the first spring 3 is extended, the slider 23 can be driven to move upward. The slider 23 can drive the top block 25 to move upward through the slide rod 24 to push the formed plate out of the forming cavity 15.

[0031] The rotating mechanism includes a spiral slide groove 31 arranged on the outer surface of the slide rod 24 , and a fixing member 32 extending into the spiral slide groove 31 is arranged on the inner wall of the slide cavity 22 .

[0032] When the slide bar 24 slides up and down in the slide cavity 22 , since the end of the fixing member 32 is located in the spiral slide groove 31 , when the slide bar 24 slides up and down, the slide bar 24 can be driven to rotate under the guidance of the spiral slide groove 31 .

[0033] The one-way discharge mechanism includes a discharge hole 33 disposed in the slide bar 24 . The upper and lower ends of the first discharge hole 33 are respectively connected to the cavity 26 and the slide cavity 22 . The first discharge hole 33 is equipped with a one-way discharge valve 34 .

[0034] When the lubricating oil in the sliding cavity 22 is squeezed, the lubricating oil can be moved out from the first discharge hole 33 into the cavity 26 , so that the sliding cavity 22 and the cavity 26 can be connected.

[0035] The one-way feeding mechanism includes a connecting pipe 4, both ends of which are respectively connected to the lower inner walls of the two sliding chambers 22, a water inlet pipe 41 is provided in the middle of the sliding chamber 22, and the water inlet pipe 41 is equipped with a one-way water inlet valve 42, and a storage chamber 43 is provided on the lower side of the body 1, and the water inlet pipe 41 is connected to the inside of the storage chamber 43.

[0036] Lubricating oil is injected into the storage chamber 43. When negative pressure is formed in the sliding chamber 22, suction force can be transmitted to the connecting pipe 4, and then the suction force is transmitted to the water inlet pipe 41. Due to the suction force, the lubricating oil in the storage chamber 43 can be sucked into the sliding chamber 22.

[0037] The outer surface of the body 1 is provided with a feed port 44 connected to the storage cavity 43, and the lower side of the body 1 is equipped with a sealing cover 45 matching the storage cavity 43. The staff can add lubricating oil into the storage cavity 43 through the feed port 44, and after turning off the sealing cover 45, the lubricating oil in the storage cavity 43 can be discharged, so that the purpose of replacing the lubricating oil can be achieved.

[0038] The left and right sides of the molding cavity 15 are both provided with connecting holes 46 that are connected to the material storage cavity 43. With such a design, when there is too much lubricating oil in the molding cavity 15, it can flow back into the molding cavity 15 through the connecting holes 46.

[0039] The left and right sides of the molded part 17 are both provided with mounting holes 5 , and telescopic rods 51 are installed in the two mounting holes 5 . The outer surfaces of the two telescopic rods 51 are both sleeved with second springs 52 , and the lower sides of the two telescopic rods 51 are both provided with pressing blocks 53 .

[0040] With such a design, when the molded part 17 is pressed into the molding cavity 15, the pressing block 53 can be pushed into the mounting hole 5, and the second spring 52 and the telescopic rod 51 begin to compress. When the molded part 17 is moved out of the molding cavity 15, the second spring 52 can be stretched to push the pressing block 53 downward to extend out of the mounting hole 5, and the molded plate can be pushed downward to be ejected, thereby preventing the plate from being stuck on the outer surface of the molded part 17.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
