Abstract
Description
Technical Field
[0001] This utility model relates to the field of forging processing technology, specifically a punching device for forging processing. Background Technology
[0002] Forgings are workpieces or blanks obtained by forging and deforming metal billets. During the forging process, it is often necessary to drill holes in them to facilitate subsequent assembly and installation.
[0003] Existing forging punching devices mainly consist of a clamping assembly and a punching mechanism. When punching a forging, the forging is first placed on the worktable, then clamped and fixed by the clamping assembly, and then the pneumatic cylinder is activated to drive the pneumatic rod to move the drill bit down. After the drill bit contacts the surface of the forging, it begins the punching operation, gradually penetrating the forging to form a hole, thus completing the punching of the forging.
[0004] Existing forging punching devices can only punch holes of specific sizes when punching forgings. When different sizes of holes need to be processed, the punching head or punching equipment needs to be changed. The change process involves multiple steps such as disassembly, installation and debugging of the punching head. These steps are complicated and cumbersome, which greatly reduces production efficiency. Therefore, a punching device for forging processing is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a punching device for forging.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A punching device for forging processing, comprising a base, two first pneumatic cylinders mounted on the top side of the base, each first pneumatic cylinder having a first pneumatic rod mounted on its working end, and a horizontal plate fixedly connected to the top of each first pneumatic rod. The horizontal plate has a sliding groove, within which a T-shaped slider is installed. A fixed seat is mounted at the bottom of the T-shaped slider, and a rotating cylinder is mounted within the fixed seat via a rotating shaft. A first electric motor is mounted on the side wall of the fixed seat, and the output end of the first electric motor is connected to one end of the rotating shaft. Four motors are mounted on the inner wall of the rotating cylinder, each motor having a drill bit of a different specification. A lead screw is rotatably mounted within the sliding groove, and the lead screw passes through the T-shaped slider. A second electric motor is mounted on the side wall of the horizontal plate. The machine's output end is connected to one end of the lead screw. To facilitate punching holes of different sizes as needed, a rotary switching mechanism is set up. The first motor is started, causing the rotating cylinder to rotate, which in turn causes the drill bit to rotate. When the required drill bit is rotated to the bottom, the first motor stops, thus enabling rapid drill bit replacement. The rotary switching mechanism allows for quick drill bit replacement in a short time, facilitating the processing of holes of different sizes and greatly improving production efficiency. When punching forgings, the second motor is started, causing the lead screw to rotate, which in turn causes the T-shaped slider to move the drill bit horizontally until the drill bit is directly above the area to be punched. The second motor then stops, and the first pneumatic cylinder is started, causing the horizontal plate and its drill bit to move vertically downward. Through the punching action of the drill bit, the punching operation of the forging is completed.
[0007] Preferably, a rotating disk is rotatably mounted on the base, and a square body is fixedly connected to the top center of the rotating disk. A second pneumatic cylinder is installed on each of the four side walls of the square body. A second pneumatic rod is assembled at the working end of each second pneumatic cylinder, and a clamping plate is fixedly connected to the other end of each second pneumatic rod. When clamping and fixing the forging, the second pneumatic cylinder is activated to expand the clamping plate outward until the clamping plate moves to contact the inner wall of the forging, thereby clamping and fixing the forging and preventing the forging from shifting during the subsequent punching process.
[0008] Preferably, the outer surface of the rotating disk is fitted with a ring rack, and a third motor is installed on the base. The output end of the third motor is fitted with a gear, and the gear meshes with the ring rack. When drilling is completed in one part of the forging, and drilling is required in another part, the third motor is started to make the gear rotate, which forces the ring rack to drive the rotating disk to rotate, thereby causing the forging, which is clamped and fixed, to rotate. Through the cooperation of the meshing rotation mechanism, the drilling operation of the forging can be completed in all directions.
[0009] Preferably, a protective cover is fixed to the base, and the annular rack and gear are both set inside the protective cover. When using the device, by setting the protective cover, the operator can be prevented from directly contacting the high-speed rotating gear and annular rack, thereby avoiding mechanical injury caused by accidental contact or improper operation.
[0010] Preferably, a dust collection hood is fixedly connected to the protective cover, a dust collection box is installed on the base, a dust collection pipe is connected between the dust collection box and the dust collection hood, a negative pressure pump is installed on the dust collection box, an air extraction pipe is connected to the input port of the negative pressure pump, an exhaust pipe is connected to the output port of the negative pressure pump, and a filter screen is installed inside the dust collection box, with the filter screen arranged around the port of the air extraction pipe. During the punching process of forgings, a large amount of dust and debris will be generated. By operating the negative pressure pump, the gas in the dust collection box is extracted through the air extraction pipe and discharged through the exhaust pipe, so that the inside of the dust collection box is in a negative pressure state. This allows the large amount of dust and debris generated during the punching process to be sucked into the dust collection box through the dust extraction pipe, thereby enabling timely cleaning and collection of dust and debris, significantly improving the operating environment and reducing pollution and hazards.
[0011] Preferably, the dust collection box is provided with a discharge port, and both sides of the discharge port are fixedly connected to limit slide rails. The two limit slide rails are slidably fitted with a sealing cover. When using the device, the discharge port can be opened or closed as needed by the cooperation of the limit slide rails and the sealing cover.
[0012] The advantages of this utility model are:
[0013] 1. In use, this utility model, in order to facilitate punching holes of different sizes as needed, is equipped with a rotary switching mechanism. The first motor is started, causing the rotating cylinder to rotate, which in turn causes the drill bit to rotate. When the required drill bit is rotated to the bottom, the first motor stops working, thereby enabling rapid replacement of the drill bit. Through the rotary switching mechanism, the drill bit can be replaced quickly in a short time, which is convenient for meeting the processing needs of holes of different sizes and greatly improves production efficiency.
[0014] 2. When using this utility model, after drilling one part of the forging is completed, if it is necessary to change to another part for drilling, the third motor is started to make the gear rotate, which forces the ring rack to drive the rotating disk to rotate, thereby causing the forging that has been clamped and fixed to rotate. Through the cooperation of the meshing rotation mechanism, the drilling operation of the forging can be completed in all directions. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Please see Figure 1-6As shown, a punching device for forging includes a base 1. Two first pneumatic cylinders 2 are mounted on the top side of the base 1.

The horizontal plate 4 has a slide groove 5. A T-shaped slider 6 is arranged in the slide groove 5. A fixed seat 7 is installed at the bottom of the T-shaped slider 6. A rotating cylinder 9 is installed in the fixed seat 7 through a rotating shaft. A first electric motor 8 is installed on the side wall that locks the fixed seat 7. The output end of the first electric motor 8 is connected to one end of the rotating shaft. Four motors 10 are installed on the inner wall of the rotating cylinder 9. Each motor 10 is equipped with a drill bit 11 of different specifications. The drill bit 11 is rotatably mounted in the slide groove 5. A lead screw 12 is provided, which passes through the T-shaped slider 6. A second motor 13 is installed on the side wall of the horizontal plate 4, and the output end of the second motor 13 is connected to one end of the lead screw 12. During operation, in order to facilitate punching holes of different sizes as needed, a rotary switching mechanism is set up to start the first motor 8, which causes the rotating cylinder 9 to rotate, and then the drill bit 11 also rotates. When the required drill bit 11 is rotated to the bottom, the first motor 8 stops working, thereby enabling the rapid replacement of the drill bit 11. Through the rotary switching mechanism, the drill bit 11 can be replaced quickly in a short time, which is convenient to meet the processing needs of holes of different sizes and greatly improves production efficiency.
[0025] A rotating disk 14 is rotatably mounted on the base 1. A square body 15 is fixed to the top center of the rotating disk 14. Second pneumatic cylinders 16 are mounted on the four side walls of the square body 15. A second pneumatic rod 17 is fitted to the actuating end of each second pneumatic cylinder 16, and a clamping plate 18 is fixed to the other end of each second pneumatic rod 17. A ring rack 19 is fitted to the outer surface of the rotating disk 14. A third electric motor 20 is mounted on the base 1. A gear 21 is installed at the output end of the third electric motor 20, and the gear 21 meshes with the ring rack 19. During operation, before drilling the forging, the forging needs to be clamped and fixed. First, the forging to be processed is placed on the rotating disk 14. The second pneumatic cylinder 16 is activated, causing the second pneumatic rod 17 to drive the clamping plate 18 to expand outward until the clamping plate 18 contacts the inner wall of the forging, thereby enabling… The forging is clamped and fixed. After the forging is clamped and fixed, when punching the forging, the second motor 13 is started, causing the lead screw 12 to rotate, which in turn causes the T-shaped slider 6 to drive the drill bit 11 to move horizontally until the drill bit 11 is directly above the part to be punched. The second motor 13 stops working. Then the first pneumatic cylinder 3 is started, causing the first pneumatic rod 3 to drive the horizontal plate 4 and its drill bit 11 to move vertically downward. Through the punching action of the drill bit 11, the punching operation of the forging can be completed. After punching one part of the forging, when it is necessary to change to another part for punching, the third motor 20 is started, causing the gear 21 to rotate, which forces the ring rack 19 to drive the rotating disk 14 to rotate, which in turn causes the clamped and fixed forging to rotate. Through the cooperation of the meshing rotation mechanism, the punching operation of the forging can be completed in all directions.
[0026] A protective cover 22 is fixedly attached to the base 1, and the ring rack 19 and the gear 21 are both set inside the protective cover 22. When using the device, by setting the protective cover 22, the operator can be prevented from directly contacting the high-speed rotating gear 21 and the ring rack 19, thereby avoiding mechanical injury caused by accidental contact or improper operation.
[0027] Please see Figure 2As shown, a dust collection hood 23 is fixedly attached to the protective cover 22, and a dust collection box 24 is installed on the base 1. A suction pipe 28 connects the dust collection box 24 and the dust collection hood 23. A negative pressure pump 25 is installed on the dust collection box 24. The input port of the negative pressure pump 25 is connected to an air extraction pipe 26, and the output port of the negative pressure pump 25 is connected to an exhaust pipe 27.

A waste discharge port is opened on the dust collection box 24, and limit slide rails 29 are fixedly attached to both sides of the waste discharge port. The two limit slide rails 29 are equipped with... The sliding assembly is equipped with a sealing cover plate 30. During operation, a large amount of dust and debris will be generated during the punching process of the forging. The negative pressure pump 25 operates to extract the gas in the dust collection box 24 through the suction pipe 26 and discharge it through the exhaust pipe 27, so that the inside of the dust collection box 24 is in a negative pressure state. This allows the large amount of dust and debris generated during the punching process to be sucked into the dust collection box 24 through the dust suction pipe 28, thereby enabling timely cleaning and collection of dust and debris, which can significantly improve the operating environment and reduce pollution and hazards.
[0028] Working Principle: Existing forging punching devices can only punch holes of specific sizes when punching forgings. When different sizes of holes need to be processed, the punching head or punching equipment needs to be changed. The change process involves multiple steps such as disassembly, installation, and debugging of the punching head, which are complex and cumbersome, greatly reducing production efficiency. Therefore, a punching device for forging processing is proposed to address the above problems. To facilitate punching holes of different sizes as needed, a rotary switching mechanism is set up. The first motor 8 is started, causing the rotating cylinder 9 to rotate, which in turn causes the drill bit 11 to rotate as well. When the required drill bit 11 is rotated to the bottom, the first motor 8 stops working, thus enabling rapid replacement of the drill bit 11. Through the rotary switching mechanism, the replacement of the drill bit 11 can be completed quickly in a short time, which can meet the processing needs of holes of different sizes and greatly improve production efficiency.
[0029] Before drilling the forging, it needs to be clamped and fixed. First, the forging to be processed is placed on the rotary table 14. The second pneumatic cylinder 16 is started, causing the second pneumatic rod 17 to drive the clamping plate 18 to expand outward until the clamping plate 18 moves to contact the inner wall of the forging, thereby clamping and fixing the forging. After the forging is clamped and fixed, when punching the forging, the second motor 13 is started, causing the lead screw 12 to rotate, which in turn causes the T-shaped slider 6 to drive the drill bit 11 to move horizontally until the drill bit 11 is directly above the part to be drilled. When the electric motor 13 stops working, the first pneumatic cylinder 3 is started, causing the first pneumatic rod 3 to drive the horizontal plate 4 and its drill bit 11 to move vertically downward. Through the punching action of the drill bit 11, the drilling operation of the forging can be completed. When drilling is completed in one part of the forging and another part needs to be drilled, the third electric motor 20 is started, causing the gear 21 to rotate, which forces the ring rack 19 to drive the rotating disk 14 to rotate, thereby causing the clamped and fixed forging to rotate. Through the cooperation of the meshing rotating mechanism, the drilling operation of the forging can be completed in all directions.
[0030] During the punching process of forgings, a large amount of dust and debris are generated. By operating the negative pressure pump 25, the gas in the dust collection box 24 is extracted through the suction pipe 26 and discharged through the exhaust pipe 27, so that the inside of the dust collection box 24 is in a negative pressure state. This allows the large amount of dust and debris generated during the punching process to be sucked into the dust collection box 24 through the dust suction pipe 28, thus enabling timely cleaning and collection of dust and debris. This significantly improves the operating environment and reduces pollution and hazards.
