Description

Technical Field

[0001] The utility model relates to the technical field of door and window production, and more specifically, to a stamping device for door and window production. Background Art

[0002] The stamping process is an efficient processing method that can quickly produce a large number of parts. In the manufacture of doors and windows, the frames, panels and other parts of doors and windows can be quickly formed by stamping machines, which greatly improves production efficiency. In addition, since the stamping mold has the characteristics of high precision and high repeatability, it can ensure that the size and shape of the parts stamped out each time are consistent. This is very important for products such as doors and windows that require precise size and shape matching, and can ensure accuracy during installation and overall aesthetics.

[0003] When stamping the aluminum alloy sheets required for the production of doors and windows, due to the light weight of aluminum alloy and the simple shape of the waste produced when stamping the aluminum alloy sheets, usually rectangular or circular, this will cause the aluminum alloy waste to be stuck in the punch hole of the bottom die after being cut and separated by the punch of the top die, and during the next stamping, the waste will adhere to the cutting oil covering the outer wall of the punch, causing the punch to move upward and bring the waste to the surface of the aluminum alloy sheet. At this time, when stamping the aluminum alloy sheet, the punch will first contact the debris, increasing the pressure on the punch and the sheet, which will lead to a decrease in the product quality of the aluminum alloy sheet and cause great harm to the die punch, so alignment is needed for improvement and optimization.

DETAILED DESCRIPTION

[0025] 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.

[0026] like Figures 1 to 7 As shown, the utility model provides a stamping device for producing doors and windows, a stamping mechanism 2 is fixedly installed on the top of a workbench 1, a stamping head 3 is arranged at the bottom of the stamping mechanism 2, a base 4 is fixedly installed on the top of the workbench 1, the base 4 is located below the stamping mechanism 2, and a bottom mold 5 is arranged inside the base 4;

[0027] A fixed platform 6 is fixedly installed inside the base 4, and a first sleeve 7 is fixedly installed inside the fixed platform 6. There are four groups of first sleeves 7, which are all arranged circumferentially inside the fixed platform 6. The second sleeves 8 are movably sleeved inside the four groups of first sleeves 7. The tops of the four groups of second sleeves 8 are fixedly connected to the bottom mold 5, and the bottom of the second sleeve 8 and the inner wall of the first sleeve 7 are elastically connected by a spring 19. A protrusion 10 is fixedly installed on the inner wall of the second sleeve 8, and a sealing ring 11 is movably installed inside the second sleeve 8. The bottom of the sealing ring 11 and the protrusion 10 are elastically connected by a spring 2 12. The outer wall of the second sleeve 8 is provided with a ventilation groove 13, and a connecting block 16 is fixedly installed on the bottom of the first sleeve 7. A sealing block 19 is movably installed inside the connecting block 16. The sealing block 19 and the inner wall of the connecting block 16 are elastically connected by a spring 3 18, and a ventilation groove 2 17 is provided on the outer wall of the connecting block 16.

[0028] When it is necessary to perform stamping operation on the sheet, the staff places the sheet on the top of the bottom die 5, and then starts the stamping mechanism 2. The punching head 3 stamps the sheet downward. At this time, the bottom die 5 is pressed downward by the punching head 3, and the bottom die 5 drives the second sleeve 8 to move along the first sleeve 7 downward. At this time, the spring 1 9 is squeezed, and the air pressure inside the first sleeve 7 and the second sleeve 8 increases. The pressure generated by the air will push the sealing block 19 downward, causing the sealing block 19 to move downward along the connecting block 16, and the spring 3 18 is squeezed, and the gas is discharged from the ventilation groove 2 17. The sheet is stamped. After the stamping is completed, the air pressure inside the first sleeve 7 and the second sleeve 8 is at a normal value. At this time, the elastic potential energy of the spring 3 18 drives the sealing block 19 to reset, so that the sealing block 19 seals the bottom of the first sleeve 7, and then the stamping mechanism 2 drives the punching head 3 to move upward. Prepare for the next stamping. At this time, the bottom mold 5 loses pressure. Through the elastic potential energy of spring 1 9, the second sleeve 8 drives the bottom mold 5 to reset. While the bottom mold 5 is resetting, the space inside the first sleeve 7 and the second sleeve 8 becomes larger, and the gas draws the sealing ring 11 downward, and the spring 2 12 is compressed. The external gas enters the interior of the second sleeve 8 from the stamping hole 15 and the air intake port 14, so that the air pressure inside the first sleeve 7 and the second sleeve 8 is balanced. Since the air intake port 14 draws the external gas into the interior of the second sleeve 8, the waste stuck in the stamping hole 15 or moving upward with the stamping head 3 is subjected to a suction force. This suction force gives the waste a downward force. At this time, the waste will fall downward through the stamping hole 15 to the inside of the collecting bin 25, and due to the conical design of the stamping hole 15, the waste is easier to fall and the discharge is more complete.

[0029] The sheet material on the top of the bottom die 5 is punched by the punching head 3, and during punching, the gas inside the first sleeve 7 and the second sleeve 8 is discharged through the vent groove 2 17, and then the bottom die 5 is reset upward by the elastic potential energy of the spring 1 9. While the bottom die 5 is reset, the outside air is sucked into the first sleeve 7 and the second sleeve 8 through the air intake port 14. Compared with the traditional device, after the punching is completed, the bottom die 5 is reset, so that the air intake port 14 generates suction, and the waste material inside the punching hole 15 is sucked downward, and the waste material is further dropped into the collecting bin 25, so that the waste material is effectively discharged and collected, and then the conical design of the punching hole 15 is used to prevent the waste material from jumping out with the punching head 3, thereby improving the production efficiency of door and window sheet materials.

[0030] The base 4 has storage slots 20 fixedly disposed on the left and right sides thereof, and vibration heads 22 are movably mounted inside the two sets of storage slots 20;

[0031] The left and right sides of the outer wall of the bottom mold 5 are provided with grooves 21, and the vibration head 22 and the inner wall of the receiving groove 20 are elastically connected through a spring four 23, and the vibration head 22 and the groove 21 are in conflict with each other.

[0032] When the bottom mold 5 moves downward, the outer wall of the bottom mold 5 will collide with the vibration head 22, causing the vibration head 22 to enter the storage groove 20. After the stamping is completed, the bottom mold 5 is reset, and while the bottom mold 5 moves upward, the vibration head 22 will hit the groove 21 on the outer wall of the bottom mold 5 through the elastic potential energy of the spring four 23, causing the bottom mold 5 to vibrate, further loosening the waste inside the punching hole 15, and cooperating with the suction force of the suction port 14 to make the waste fall.

[0033] Through the elastic potential energy of spring four 23, the vibration head 22 will hit the groove 21 on the outer wall of the bottom mold 5 while the bottom mold 5 is reset upward, causing the bottom mold 5 to vibrate. Compared with the traditional device, the device loosens the waste material inside the punching hole 15 at the center of the bottom mold 5 through the vibration of the bottom mold 5, and cooperates with the suction force generated by the suction port 14 to effectively prevent the waste material from clogging the punching hole 15, making the discharge more thorough.

[0034] An air intake port 14 is provided inside the bottom mold 5 , a punching hole 15 is provided at the center of the bottom mold 5 , one end of the air intake port 14 is connected to the punching hole 15 , and the other end of the air intake port 14 is connected to the second sleeve 8 .

[0035] The air intake port 14 and the punching hole 15 are interconnected, so that the external air can be sucked into the interior of the first sleeve 7 and the second sleeve 8 by the air intake port 14, thereby generating suction force on the waste material inside the punching hole 15, causing the waste material to fall downward.

[0036] The sealing ring 11 contacts the inner wall of the bottom mold 5 through the spring 2 12 , and the sealing ring 11 seals the ventilation groove 1 13 .

[0037] When the bottom mold 5 moves upward, the air inside the first sleeve 7 and the second sleeve 8 pulls the sealing ring 11 and inhales the external gas from the ventilation groove 13. After the air pressure is balanced, the elastic potential energy of the spring 2 12 drives the sealing ring 11 to seal the ventilation groove 13.

[0038] The first sleeve 7 and the connecting block 16 are connected to each other, and the sealing block 19 seals the first sleeve 7 through the spring three 18.

[0039] When the bottom mold 5 moves downward, the air inside the first sleeve 7 and the second sleeve 8 pushes the sealing block 19 and is discharged from the second ventilation groove 17. After the air pressure is balanced, the elastic potential energy of the spring three 18 drives the sealing block 19 to seal the first sleeve 7.

[0040] The top diameter of the punching hole 15 corresponds to the punching head 3 , the bottom diameter of the punching hole 15 gradually increases, and the punching hole 15 is conical.

[0041] The conical design of the punching hole 15 makes it easier for the waste to fall and difficult for it to move upward with the punching head 3 .

[0042] A fixed frame 24 is fixedly installed at the bottom of the workbench 1 , and a collecting bin 25 is movably installed inside the fixed frame 24 . The collecting bin 25 is responsible for receiving stamping waste.

[0043] The working principle and use process of this utility model:

[0044] When it is necessary to perform stamping operation on the sheet, the staff places the sheet on the top of the bottom die 5, and then starts the stamping mechanism 2. The punching head 3 stamps the sheet downward. At this time, the bottom die 5 is pressed downward by the punching head 3, and the bottom die 5 drives the second sleeve 8 to move along the first sleeve 7 downward. At this time, the spring 1 9 is squeezed, and the air pressure inside the first sleeve 7 and the second sleeve 8 increases. The pressure generated by the air will push the sealing block 19 downward, causing the sealing block 19 to move downward along the connecting block 16, and the spring 3 18 is squeezed, and the gas is discharged from the ventilation groove 2 17. The sheet is stamped. After the stamping is completed, the air pressure inside the first sleeve 7 and the second sleeve 8 is at a normal value. At this time, the elastic potential energy of the spring 3 18 drives the sealing block 19 to reset, so that the sealing block 19 seals the bottom of the first sleeve 7, and then the stamping mechanism 2 drives the punching head 3 to move upward. Prepare for the next stamping. At this time, the bottom mold 5 loses pressure. Through the elastic potential energy of spring 1 9, the second sleeve 8 drives the bottom mold 5 to reset. While the bottom mold 5 is resetting, the space inside the first sleeve 7 and the second sleeve 8 becomes larger, and the gas draws the sealing ring 11 downward, and the spring 2 12 is compressed. The external gas enters the interior of the second sleeve 8 from the stamping hole 15 and the air intake port 14, so that the air pressure inside the first sleeve 7 and the second sleeve 8 is balanced. Since the air intake port 14 draws the external gas into the interior of the second sleeve 8, the waste stuck in the stamping hole 15 or moving upward with the stamping head 3 is subjected to a suction force. This suction force gives the waste a downward force. At this time, the waste will fall downward through the stamping hole 15 to the inside of the collecting bin 25, and due to the conical design of the stamping hole 15, the waste is easier to fall and the discharge is more complete.

[0045] When the bottom mold 5 moves downward, the outer wall of the bottom mold 5 will collide with the vibration head 22, causing the vibration head 22 to enter the storage groove 20. After the stamping is completed, the bottom mold 5 is reset, and while the bottom mold 5 moves upward, the vibration head 22 will hit the groove 21 on the outer wall of the bottom mold 5 through the elastic potential energy of the spring four 23, causing the bottom mold 5 to vibrate, further loosening the waste inside the punching hole 15, and cooperating with the suction force of the suction port 14 to make the waste fall.
