Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stamping die technology, specifically relating to a stamping die for processing irregularly shaped parts. Background Technology
[0002] Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to sheet metal at room temperature, causing it to separate or plastically deform, thereby obtaining the desired parts.
[0003] A type of irregularly shaped part on the market (see reference) Figure 1 When processing the irregular part (label 1 - irregular part body), mounting holes for connecting with other components need to be punched on the irregular part. The irregular part includes an arc-shaped part, a first inclined part, and a second inclined part. The arc-shaped part is smoothly connected to the first inclined part, and the first inclined part and the second inclined part are vertically arranged. The mounting holes are opened at the position of the arc-shaped part.
[0004] When holes are made in the curved portion of an irregularly shaped part, the punch compresses the part. However, the curved portion lacks adequate support, causing it to bend downwards during compression. This irreversible deformation prevents the curved portion from fitting snugly with the connecting component during subsequent assembly, resulting in gaps and loosening of the connection. Therefore, this application proposes a stamping die for processing irregularly shaped parts. Utility Model Content
[0005] The purpose of this utility model is to provide a stamping die for processing irregularly shaped parts, so as to solve the problem mentioned in the background art that when holes are made in the arc-shaped part of the irregularly shaped part, the punch will squeeze the irregularly shaped part, but the arc-shaped part of the irregularly shaped part lacks corresponding support. This causes the irregularly shaped part to bend downward during the process of being squeezed by the punch, which is not conducive to the subsequent connection of the irregularly shaped part.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for processing irregularly shaped parts, comprising a left positioning block, a right positioning block, and a bracket. The left positioning block is provided with a first working surface that mates with the body of the irregularly shaped part, and the right positioning block is provided with a second working surface that mates with the body of the irregularly shaped part. The body of the irregularly shaped part includes an arc-shaped portion, a first inclined portion, and a second inclined portion. The arc-shaped portion and the first inclined portion are smoothly connected, and the first inclined portion and the second inclined portion are perpendicularly arranged between them.
[0007] The bracket is equipped with a stamping power mechanism and a punch, and the output end of the stamping power mechanism is connected to the punch.
[0008] A stamping auxiliary block is provided below the mounting hole of the irregular part body, an auxiliary groove that cooperates with the stamping auxiliary block is provided in the left positioning block, and a feeding groove that communicates with the auxiliary groove is provided in the left positioning block.
[0009] A spring is installed inside the auxiliary groove. One end of the spring is connected to the inner wall of the auxiliary groove, and the other end of the spring is connected to the stamping auxiliary block.
[0010] Preferably, the left positioning block abuts against the right positioning block, and the left positioning block and the right positioning block are connected by bolts.
[0011] Preferably, a guide groove is provided at the position of the auxiliary groove, and a guide block is provided on the stamping auxiliary block, with the guide block slidingly engaging with the guide groove.
[0012] Preferably, there are two guide grooves, and the two guide grooves are arranged in a circumferential array around the center line of the auxiliary groove.
[0013] Preferably, the feeding trough is configured in a funnel shape.
[0014] Preferably, the left positioning block is provided with an installation groove, and the installation groove is provided with a high-pressure gas exhaust pipe, a gas storage tank, a pressure stabilizing valve, a power pump, and an air inlet pipe. The power pump is connected to the outside air through the air inlet pipe, the power pump's exhaust pipe is connected to the gas storage tank, the gas storage tank is connected to the high-pressure gas exhaust pipe, and a pressure stabilizing valve is installed on the gas storage tank.
[0015] Preferably, the stamping auxiliary block is provided with a baffle that can block the exhaust port of the high-pressure gas exhaust pipe.
[0016] Preferably, the support is provided with a waste collection box, which is located below the material discharge chute.
[0017] Preferably, the left positioning block has a first side plate at both its front and rear ends, and the height of the first side plate is higher than the height of the left positioning block.
[0018] Preferably, the right positioning block has a second side plate at both its front and rear ends, and the height of the second side plate is higher than the height of the right positioning block.
[0019] Beneficial effects:
[0020] This utility model provides a stamping die for processing irregularly shaped parts. A stamping auxiliary block and other components are arranged below the mounting hole in the irregularly shaped part body. The left and right positioning blocks are in contact with the lower end face of the irregularly shaped part body, providing support. A spring connected to the stamping auxiliary block provides an upward thrust, causing the stamping auxiliary block to press against the lower end face of the irregularly shaped part body. When the guide block is at its highest point, i.e., when the guide block presses against the upper end face of the guide groove, the stamping auxiliary block reaches its highest position. At this time, the irregularly shaped part body, which is in contact with the left positioning block, is in contact with the upper end face of the stamping auxiliary block. Thus, when the stamping power mechanism and punch press the hole in the irregularly shaped part body, the stamping auxiliary block supports the area around the mounting hole, preventing the irregularly shaped part body around the mounting hole from sinking. This prevents the area around the stamped mounting hole from collapsing, reducing the likelihood of gaps between the stamped part and other components during subsequent installation, resulting in a tighter assembly.

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0029] like Figures 1-5As shown in the figure, a stamping die for processing irregular parts provided by this utility model includes a left positioning block 2, a right positioning block 3, and a bracket 5. The left positioning block 2 is provided with a first working surface that cooperates with the body 1 of the irregular part, and the right positioning block 3 is provided with a second working surface that cooperates with the body 1 of the irregular part. The body 1 of the irregular part includes an arc-shaped part, a first inclined part, and a second inclined part. The arc-shaped part and the first inclined part are smoothly connected. The first inclined part and the second inclined part are vertically arranged. The first working surface covers a portion of the arc-shaped part, the first inclined part, and the second inclined part, and the second working surface covers the portion of the second inclined part that is not covered by the first working surface.
[0030] Specifically, the left positioning block 2 rests against the right positioning block 3, and the left positioning block 2 and the right positioning block 3 are connected by bolts.
[0031] In order to make mounting holes on the irregular part body 1, a stamping power mechanism 4 and a punch are provided on the bracket 5. The stamping power mechanism 4 can be a cylinder. The output end of the stamping power mechanism 4 is connected to the punch. The punch is aligned with the position on the irregular part body 1 where the mounting holes need to be made. Two mounting holes need to be made on the irregular part body 1, so two punches are also provided.
[0032] To support the position of the mounting hole stamped out of the irregular part body 1, a stamping auxiliary block 6 is provided below the mounting hole of the irregular part body 1. An auxiliary groove that cooperates with the stamping auxiliary block 6 is provided in the left positioning block 2. It should be noted that a guide groove 8 is provided at the position of the auxiliary groove. A guide block is provided on the stamping auxiliary block 6. The guide block and the guide groove 8 are slidably engaged. There are two guide grooves 8, and the two guide grooves 8 are arranged in a circular array around the center line of the auxiliary groove. A feeding groove 9 that communicates with the auxiliary groove is provided in the left positioning block 2. The feeding groove 9 is shaped like a horn.
[0033] Specifically, a spring 7 is installed in the auxiliary groove. One end of the spring 7 is connected to the inner wall of the auxiliary groove, and the other end of the spring 7 is connected to the stamping auxiliary block 6. The diameter of the stamping auxiliary block 6 is larger than the diameter of the mounting hole in the irregular part body 1. The spring 7 can provide an upward thrust to the stamping auxiliary block 6, so that the stamping auxiliary block 6 abuts against the lower end face of the irregular part body 1. When the guide block is at its highest point, that is, when the guide block abuts against the upper end face of the guide groove 8, the stamping auxiliary block 6 reaches its highest point. At this time, the irregular part body 1 attached to the left positioning block 2 is in contact with the upper end face of the stamping auxiliary block 6. In this way, when the stamping power mechanism 4 and the punch press the hole in the irregular part body 1, the stamping auxiliary block 6 will support the area around the mounting hole of the irregular part body 1, preventing the irregular part body 1 around the mounting hole from sinking. In this way, the area around the stamped mounting hole will not collapse, and during subsequent installation, it is not easy to create gaps between it and other parts, resulting in a tighter assembly. Spring 7 is a metal spring with a length of 15cm and a wire diameter of 10mm.
[0034] To allow the waste material generated during the stamping of the mounting holes to be discharged quickly, a mounting groove is provided in the left positioning block 2. The mounting groove is equipped with a high-pressure gas exhaust pipe 10, an air tank 11, a pressure regulating valve 12, a power pump 13, and an air inlet pipe 14. The power pump 13 is connected to the outside air through the air inlet pipe 14. The exhaust pipe of the power pump 13 is connected to the air tank 11. The air tank 11 is connected to the high-pressure gas exhaust pipe 10. A pressure regulating valve 12 is installed on the air tank 11 to limit the maximum gas pressure inside the air tank 11. The pressure regulating valve 12 can discharge excess gas when the gas pressure inside the air tank 11 exceeds the limit, thus preventing the gas pressure inside the air tank 11 from becoming too high.
[0035] Specifically, a baffle 17 is provided on the stamping auxiliary block 6, which can block the exhaust port of the high-pressure gas exhaust pipe 10.
[0036] The power pump 13 sends air from the outside into the air storage tank 11 through the air inlet pipe 14 and stores it. The continuous intake of air increases the pressure of the gas in the air storage tank 11. When the stamping power mechanism 4 drives the punch to open the mounting hole on the irregular part body 1, it will squeeze the stamping auxiliary block 6 and cause the stamping auxiliary block 6 to descend. The waste part stamped out on the irregular part body 1 is located on the upper side of the stamping auxiliary block 6. As the punch moves down, it falls to the position of the high pressure gas exhaust pipe 10. At this time, the high pressure gas exhaust pipe 10 loses the obstruction of the baffle 17 and the stamping auxiliary block 6. The gas inside the air storage tank 11 is blown into the auxiliary groove through the exhaust port. The waste part located on the upper side of the stamping auxiliary block 6 is blown to the unloading groove 9 and discharged through the unloading groove 9. In this way, the unloading of the waste part is completed.
[0037] In order to collect waste parts, a waste part collection box 15 is provided on the support 5, and the waste part collection box 15 is located below the feed chute 9.
[0038] In order to restrict the irregular part body 1, a first side plate 16 is provided at both the front and rear ends of the left positioning block 2, and a second side plate is provided at both the front and rear ends of the right positioning block 3. The height of the first side plate 16 is higher than the height of the left positioning block 2, and the height of the second side plate is higher than the height of the right positioning block 3.
[0039] In summary, this utility model embodiment provides a stamping die for processing irregularly shaped parts. A stamping auxiliary block 6 and other components are provided below the mounting hole inside the irregularly shaped part body 1. A spring 7 provides an upward thrust to the stamping auxiliary block 6, causing it to abut against the lower end face of the irregularly shaped part body 1. When the guide block is at its highest point, i.e., when it abuts against the upper end face of the guide groove 8, the stamping auxiliary block 6 reaches its highest position. At this time, the irregularly shaped part body 1, which is attached to the left positioning block 2, is in contact with the upper end face of the stamping auxiliary block 6. Thus, when the stamping power mechanism 4 and the punch press out holes in the irregularly shaped part body 1, the stamping auxiliary block 6 supports the area around the mounting hole, preventing the irregularly shaped part body 1 around the mounting hole from sinking. This prevents the area around the stamped mounting hole from collapsing, making it less likely for gaps to form between it and other components during subsequent installation, resulting in a tighter assembly.

Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
