Description

Technical Field

[0001] This application relates to the field of camera housing processing technology, specifically to a precision machining device for aluminum components used in cameras. Background Technology

[0002] Explosion-proof cameras belong to the category of explosion-proof monitoring products and are a cross-product of the explosion-proof and monitoring industries. The working principle of explosion-proof cameras is to suppress the generation and occurrence of the four elements of an explosion, ensuring that electrical products can still work normally in high-risk environments. Explosion-proof cameras are widely used in dangerous places such as chemical plants, oil fields, and coal mines to effectively monitor safe production and accident occurrences.

[0003] In the current processing of camera aluminum housings, which are primarily cylindrical with relatively thin walls, the existing method of stamping involves fitting the cylindrical housing onto a stamping post with a matching diameter. While this provides support and rigidity, the diameter of the housing varies in actual production, often being slightly smaller or larger than the stamping post. For smaller diameter housings, fitting the post becomes difficult, or an interference fit results in clamping issues. For larger diameter housings, a large gap forms between the housing and the post, causing slight movement during stamping and reducing stamping accuracy. Therefore, regardless of whether it's an interference fit or a clearance fit, traditional rigid stamping posts are ill-suited for processing cylindrical housings of varying sizes. Meanwhile, in actual processing, cylindrical shells often require holes of different diameters to be machined at different locations. Existing equipment typically requires removing the cylindrical shell from the stamping press and re-clamping it when the machining position needs to be changed or the hole diameter altered, or replacing the corresponding stamping die. This repeated disassembly and reassembly of the workpiece and replacement of the die is extremely cumbersome, severely impacting processing efficiency. Furthermore, multiple clamping operations can easily introduce positioning errors, making it difficult to guarantee the relative positional accuracy between holes at different locations, and failing to achieve precise "follow-up" support for the machining position. In addition, after the stamping process is completed, burrs are often generated on the edges of the stamped holes. In order to ensure that the holes are smooth and flat, it is usually necessary to spend extra manpower and grinding equipment to grind the burrs, which is not only troublesome to operate, but also increases production costs. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the purpose of this application is to provide a precision machining device for aluminum components of cameras.

[0005] The precision machining device for aluminum components of a camera described in this application includes a base frame, a bracket fixedly connected to the base frame, a conveyor belt mounted on the bracket, and a plurality of U-shaped placement plates for placing cylindrical shells fixedly connected to the conveyor belt. The bracket is connected to a power mechanism, and multiple support columns are fixed to the power mechanism. The power mechanism can drive the support columns to move back and forth and up and down. Each support column has a sliding groove, and a first electric push rod is fixed to the bottom of the support column. A first electric wheel is installed on the telescopic part of the first electric push rod. A first electric slide rail is fixed inside the support column, and a first electric slider is slidably connected to the first electric slide rail. Multiple second electric push rods are fixed to the first electric slider, and a support block located in the sliding groove is fixed to the telescopic part of the second electric push rod. The upper surface of the support block is slightly arc-shaped, allowing it to better fit against the inner wall of the cylindrical shell. Each support block has a limiting hole of different diameter, and a channel communicating with the limiting hole is formed inside the support block. It also includes a stamping mechanism, which is connected to the bracket for punching holes in the cylindrical shell.

[0006] Furthermore, it is particularly preferred that the limiting hole is shaped like a frustum and the channel is inclined.

[0007] Furthermore, it is particularly preferred that the first electric wheel is made of rubber, thereby increasing the friction between the first electric wheel and the cylindrical shell.

[0008] Furthermore, it is particularly preferred that a sensing plate is fixedly connected to the support block, a touch rod acting on the sensing plate is slidably connected inside the support block, a spring is fixedly connected to the outer ring surface of the touch rod, one end of the spring is fixedly connected to the support block, a first elastic telescopic tube is fixedly connected to the end of the touch rod away from the spring, and a connecting wire is fixedly connected to the telescopic part of the first elastic telescopic tube.

[0009] Furthermore, it is particularly preferred that the connecting wire is arranged in an arc shape, so that the connecting wire can better fit the inner wall of the cylindrical shell.

[0010] Furthermore, it is particularly preferred that the power mechanism includes a first fixed plate and a second electric slide rail fixedly connected to the first fixed plate. A second electric slider is slidably connected to the second electric slide rail, and a support plate is fixedly connected to the second electric slider. A plurality of first hydraulic cylinders are fixedly connected to the support plate, and the telescopic parts of the first hydraulic cylinders are fixedly connected to the support column.

[0011] Furthermore, it is particularly preferred that the stamping mechanism includes a support frame and a fixed frame fixedly connected to the support frame. A plurality of third electric slide rails are fixedly connected to the fixed frame, and a third electric slider is slidably connected to the third electric slide rails. A number of second hydraulic cylinders, the same number as the support blocks, are fixedly connected to the third electric sliders. A fixed column is rotatably connected to the second hydraulic cylinders. A stamping head is fixedly connected to the fixed column. A plurality of second fixed plates are fixedly connected to the fixed frame, and a second electric wheel is rotatably connected to the second fixed plate.

[0012] Furthermore, it is particularly preferred that the telescopic part of the second hydraulic cylinder is fixedly connected to a DD motor, the rotating part of the DD motor is connected to a fixed column, and the punch head is fixedly connected to a first grinding ring, a grinding tube and a second grinding ring from top to bottom. The first grinding ring and the second grinding ring both have elastic deformation capability, and the interior of the first grinding ring and the second grinding ring are both hollow. A connecting tube connects the first grinding ring and the second grinding ring.

[0013] Furthermore, it is particularly preferred that a first corrugated expansion tube is fixedly connected inside the supporting column, and a second corrugated expansion tube connected to the first corrugated expansion tube and communicating with the channel is fixedly connected to the first corrugated expansion tube.

[0014] Furthermore, it is particularly preferred that the punch head has a through hole that communicates with the first grinding ring, and a second elastic telescopic tube is fixedly connected to the through hole, and a push rod is fixedly connected to the telescopic part of the second elastic telescopic tube.

[0015] The precision machining device for aluminum components in a camera described in this application has the following advantages: A. The present invention uses the first electric wheel to abut against the cylindrical shell, thereby fixing the cylindrical shell supported on the support column, thus preventing the cylindrical shell from shifting or slightly shaking during subsequent processing, which would affect the precision of the cylindrical shell processing.

[0016] B. The present invention also features an arc-shaped upper surface of the support block, which better fits the inner wall of the cylindrical shell, thereby providing stable rigid support for the stamping area of ​​the cylindrical shell. This effectively avoids the deformation of the cylindrical shell at the punching position due to the thin wall thickness of the aluminum cylindrical shell of the camera during stamping if there is a lack of corresponding internal support at the stamping point, which would affect the stamping accuracy and processing quality of the cylindrical shell.

[0017] C. This invention also uses the aforementioned support column to axially position the cylindrical shell and utilizes the first electric wheel to apply preload from the inner wall for secure fixing. Simultaneously, the support block provides precise rigid support to the processing area. This combination solves the problem in the prior art where, during stamping, the cylindrical shell is typically fitted onto a stamping column with a diameter matching its own. While this method provides support and rigidity, the diameter of the cylindrical shell often varies slightly smaller or larger than the stamping column due to dimensional tolerances in actual production. Regarding the diameter of the column, when dealing with cylindrical shells with smaller diameters, it is difficult to fit the cylindrical shell onto the stamping column, or the cylindrical shell will have an interference fit that is difficult to insert and remove, leading to clamping difficulties. When dealing with cylindrical shells with larger diameters, a large gap will form between the cylindrical shell and the stamping column, causing the cylindrical shell to move slightly during stamping, resulting in a decrease in stamping accuracy. Therefore, whether it is an interference fit or a clearance fit, traditional rigid stamping columns are difficult to adapt to the processing requirements of cylindrical shells of different actual sizes, making traditional stamping columns less practical.

[0018] D. This invention also addresses the issue that if there are a few burrs on the lower edge of the hole, the connecting wire will directly press over these burrs. If there are a large number of burrs or slight flanges on the lower edge of the hole, the large number of burrs or the flanged edge of the hole will obstruct the connecting wire and force it to move towards the sensing plate. The touch rod and the first elastic telescopic tube move synchronously with the connecting wire, the spring is compressed, and one end of the touch rod will be inserted into the round hole on the sensing plate. At this time, the sensing plate will transmit an alarm signal to the alarm on the equipment. This allows the operator to immediately know the condition of the hole after punching, and also indicates that the punching head is dull, which causes a large number of burrs or slight flanges on the lower edge of the punched round hole. Based on this situation, the operator can replace and maintain the punching head in the first instance to prevent the punching head from affecting subsequent punching.

[0019] E. The present invention also drives the support block to move back and forth by means of the first electric slider, so that the limiting holes of different diameters can be precisely aligned with the punching heads of different specifications, thereby providing "follow-up" internal rigid support for punching operations at different positions. This effectively avoids the tedious operation of repeatedly disassembling and assembling workpieces or changing molds due to changing processing positions or hole diameters, greatly improving processing efficiency and the adaptability of equipment to punching tasks of different hole diameters, and ensuring the forming accuracy of the cylindrical shell under diverse processing requirements. F. The present invention also significantly reduces the processing time of the cylindrical shell by first stamping the cylindrical shell and then polishing the stamped holes by rotating the first polishing ring, polishing tube and second polishing ring. It also solves the problem in the prior art that after the cylindrical shell is stamped, there will be burrs on the stamped holes. In order to ensure the smoothness and flatness of the holes, it is often necessary to spend extra manpower and polishing equipment to polish the burrs. This is not only troublesome to operate, but also increases the cost. Attached Figure Description

Example 1

[0024] A precision machining device for aluminum components used in cameras, such as Figure 1-10 As shown, it includes a base frame 1, a support 2 fixedly connected to the base frame 1, a conveyor belt 3 installed on the support 2, and multiple U-shaped placement plates 4 for placing cylindrical shells fixedly connected to the conveyor belt 3. A power mechanism is connected to the bracket 2, and multiple support columns 5 are fixed to the power mechanism. The power mechanism can drive the support columns 5 to move back and forth and up and down. A sliding groove 5a is opened on the support column 5. A first electric push rod 6 is fixed to the bottom of the support column 5. A first electric wheel 7 is installed on the telescopic part of the first electric push rod 6. A first electric slide rail 8 is fixed inside the support column 5. A first electric slider 9 is slidably connected to the first electric slide rail 8. Multiple second electric push rods 10 are fixed to the first electric slider 9. A support block 11 located in the sliding groove 5a is fixed to the telescopic part of the second electric push rod 10. The upper surface of the support block 11 is slightly arc-shaped, so that the upper surface of the support block 11 fits better against the inner wall of the cylindrical shell. Each support block 11 has a limiting hole 11a of different diameter. A channel 11b communicating with the limiting hole 11a is opened inside the support block 11. It also includes a stamping mechanism, on which the support 2 is connected a stamping mechanism for punching holes in the cylindrical shell.

[0025] The limiting hole 11a is shaped like a frustum, and the channel 11b is inclined.

[0026] The first electric wheel 7 is made of rubber to increase the friction between the first electric wheel 7 and the cylindrical shell.

[0027] A sensing element 12 is fixedly connected to the support block 11. A touch rod 13 that acts on the sensing element 12 is slidably connected inside the support block 11. A spring 14 is fixedly connected to the outer ring surface of the touch rod 13. One end of the spring 14 is fixedly connected to the support block 11. A first elastic telescopic tube 15 is fixedly connected to the end of the touch rod 13 away from the spring 14. A connecting wire 16 is fixedly connected to the telescopic part of the first elastic telescopic tube 15.

[0028] The connecting wire 16 is arc-shaped, which allows it to better fit the inner wall of the cylindrical shell.

[0029] The power mechanism includes a first fixed plate 21 and a second electric slide rail 22 fixedly connected to the first fixed plate 21. A second electric slider 23 is slidably connected to the second electric slide rail 22. A support plate 24 is fixedly connected to the second electric slider 23. A plurality of first hydraulic cylinders 25 are fixedly connected to the support plate 24. The telescopic part of the first hydraulic cylinder 25 is fixedly connected to the support column 5.

[0030] The stamping mechanism includes a support frame 41 and a fixed frame 42 fixedly connected to the support frame 41. Multiple third electric slide rails 43 are fixedly connected to the fixed frame 42. Third electric sliders 44 are slidably connected to the third electric slide rails 43. The third electric sliders 44 are fixedly connected to the third electric sliders 44 in the same number as the support blocks 11. The second hydraulic cylinders 45 are rotatably connected to the fixed columns 46. A stamping head 47 is fixedly connected to the fixed columns 46. Multiple second fixed plates 48 are fixedly connected to the fixed frame 42. Second electric wheels 49 are rotatably connected to the second fixed plates 48.

[0031] When using the precision machining device for aluminum components used in cameras, the operator first places the cylindrical shell to be machined on the U-shaped placement plate 4. The U-shaped placement plate 4 acts as a limit to prevent the cylindrical shell from rolling during movement, thus preventing the support column 5 from entering the cylindrical shell. During this process, the conveyor belt 3 is simultaneously controlled to move the U-shaped placement plate 4 and the cylindrical shell to the right, so that the cylindrical shell on the U-shaped placement plate 4 is moved to the front of the support column 5. Figure 1 As shown, at this time, the second electric slider 23 is controlled to slide forward on the second electric slide rail 22. The support plate 24 and the parts connected to it move forward synchronously with the second electric slider 23. Then, the support column 5 and the parts connected to it will enter the corresponding cylindrical shell. Next, the telescopic part of the first hydraulic cylinder 25 is controlled to retract to drive the support column 5 to rise and abut against the inner wall of the cylindrical shell. At this time, the upper surface of the support block 11 will also contact the inner wall of the cylindrical shell. It should be noted that during the process of the support column 5 contacting the inner wall of the cylindrical shell, the inner wall of the cylindrical shell will first contact the connecting wire 16 and force the connecting wire 16 to move up and down on the support block 11. The elastic telescopic tube 15 is compressed, and then the support column 5 contacts the inner wall of the cylindrical shell. Then, as the support column 5 continues to rise, it will drive the cylindrical shell away from the U-shaped placement plate 4. The rising cylindrical shell will then contact the second electric wheel 49. At the same time, during the rising process of the cylindrical shell, the telescopic part of the first electric push rod 6 is extended to drive the first electric wheel 7 to move down until it contacts the inner wall of the cylindrical shell. Thus, the first electric wheel 7's contact with the cylindrical shell fixes the cylindrical shell supported on the support column 5, thereby preventing the cylindrical shell from shifting or slightly shaking during subsequent processing, which would affect the precision of the cylindrical shell processing. Next, when a small-diameter circular hole needs to be punched at the top of the cylindrical shell, the second hydraulic cylinder 45 at the rear drives the fixed column 46 to move downwards, and the punching head 47 moves downwards synchronously with the fixed column 46. The punching head 47 then punches the designated position on the cylindrical shell. During the punching process, because the limiting hole 11a on the rear support block 11 is directly opposite the punching head 47, and the upper surface of the support block 11 is arc-shaped, it can better fit the inner wall of the cylindrical shell, thus providing stable rigid support for the punching area of ​​the cylindrical shell. This effectively avoids the situation where, due to the thin wall thickness of the camera's aluminum cylindrical shell, the punching point lacks corresponding internal support, which could lead to... This causes deformation of the cylindrical shell at the punching location, which in turn affects the stamping accuracy and processing quality of the cylindrical shell. After stamping, the punch head 47 will enter the limiting hole 11a. At this time, the waste piece generated by stamping will be pressed into the limiting hole 11a by the punch head 47. Since the limiting hole 11a is set in a frustum shape, the waste piece can fall out of the limiting hole 11a more easily, thus avoiding the waste piece from getting stuck in the limiting hole 11a. Then, the waste piece will fall on the inclined channel 11b and slide down along the inclined channel 11b into the support column 5. Finally, it will be discharged through the slide groove 5a on the bottom of the support column 5. In this way, the stamping of the cylindrical shell is completed. Thus, the cylindrical shell is axially positioned by the aforementioned support column 5, and firmly fixed by applying preload from the inner wall using the first electric wheel 7. Simultaneously, the support block 11 provides precise rigid support to the processing area. This combination solves the problem in the prior art where, during stamping, the cylindrical shell is typically fitted onto a stamping column with a diameter matching its own. While this method provides support and rigidity, the diameter of the cylindrical shell often varies slightly smaller or larger than the stamping column due to dimensional tolerances in actual production. Regarding the diameter of the stamping column, when dealing with cylindrical shells with smaller diameters, it is difficult to fit the cylindrical shell onto the stamping column, or the cylindrical shell will have an interference fit that is difficult to insert and remove, leading to clamping difficulties. When dealing with cylindrical shells with larger diameters, a large gap will form between the cylindrical shell and the stamping column, causing the cylindrical shell to move slightly during stamping, resulting in a decrease in stamping accuracy. Therefore, whether it is an interference fit or a clearance fit, traditional rigid stamping columns are difficult to adapt to the processing requirements of cylindrical shells of different actual sizes, making traditional stamping columns less practical. Next, after the cylindrical shell is punched, the second hydraulic cylinder 45 at the rear is controlled to move the fixed column 46 upward and reset. Then, the telescopic part of the second electric push rod 10 is controlled to retract, driving the support block 11 downward. The sensing plate 12, the contact rod 13, the spring 14, the first elastic telescopic tube 15, and the connecting wire 16 move downward synchronously with the support block 11. During this process, the upper surface of the support block 11 will detach from the inner wall of the cylindrical shell, and at the same time, the first elastic telescopic tube 15 gradually resets from the compressed state, thereby driving the connecting wire 16 to generate an upward movement tendency, ensuring that the arc-shaped connecting wire 16 can still closely fit the inner wall of the cylindrical shell. Then, the first electric slider 9 is controlled to move backward on the first electric slide rail 8. The second electric push rod 10, the support block 11, and the parts connected to them move backward synchronously with the first electric slider 9, so that the connecting wire 16 passes through the punched position on the cylindrical shell. During the process, if there are a few burrs on the lower edge of the hole, the connecting wire 16 will directly press over these burrs. If there are a lot of burrs or slight folds on the lower edge of the hole, the burrs or folds on the hole edge will block the connecting wire 16 and force the connecting wire 16 to move towards the sensing plate 12. The touch rod 13 and the first elastic telescopic tube 15 move synchronously with the connecting wire 16, the spring 14 is compressed, and then one end of the touch rod 13 will be inserted into the round hole on the sensing plate 12. At this time, the sensing plate 12 will transmit an alarm signal to the alarm on the equipment, so that the staff can immediately know the condition of the hole after punching. It also indicates that the punching head 47 is dull, which will cause a lot of burrs or slight folds on the lower edge of the punched round hole. Based on this situation, the staff can replace and maintain the punching head 47 in the first time to prevent the punching head 47 from affecting the subsequent punching. Next, when the bottom of the cylindrical shell needs to be stamped, the second electric wheel 49 is controlled to rotate, simultaneously cooperating with the rotation of the first electric wheel 7. The second electric wheel 49 and the first electric wheel 7 then drive the cylindrical shell to rotate stably on the support column 5, ensuring that the stamping position at the bottom of the cylindrical shell is directly below the stamping head 47. This automatic rotation of the cylindrical shell by the second electric wheel 49 and the first electric wheel 7 eliminates the need for workers to remove the cylindrical shell from the stamping machine and reinstall it, thus improving stamping efficiency. Then, when it is necessary to ensure that the small-diameter holes stamped at the top and bottom of the cylindrical shell are on the same vertical axis, the above stamping steps are repeated. When punching a larger diameter circular hole, the first electric slider 9 is controlled to move backward on the first electric slide rail 8. The second electric push rod 10, the support block 11, and the parts connected to them move backward synchronously with the first electric slider 9 until the support block 11 with a larger limit hole 11a moves to the area to be punched. During this process, the third electric slider 44 is controlled to slide backward on the third electric slide rail 43. The second hydraulic cylinder 45, the fixed column 46, and the punch head 47 move backward synchronously with the third electric slider 44 until the punch head 47 with a larger diameter moves directly above the area to be punched. Then, the above punching steps are repeated to process a circular hole of the required diameter on the cylindrical shell. Thus, by driving the support block 11 to move back and forth through the first electric slider 9, the limiting holes 11a of different diameters can be precisely aligned with the punching heads 47 of different specifications, thereby providing "follow-up" internal rigid support for punching operations at different positions. This effectively avoids the tedious operation of repeatedly disassembling and assembling workpieces or changing molds due to changing processing positions or hole diameters, greatly improving processing efficiency and the adaptability of the equipment to punching tasks of different hole diameters, and ensuring the forming accuracy of the cylindrical shell under diverse processing requirements. Example 2

[0032] Based on Example 1, such as Figure 5 , Figure 11-12 As shown, the telescopic part of the second hydraulic cylinder 45 is fixedly connected to the DD motor 51, the rotating part of the DD motor 51 is connected to the fixed column 46, and the punch head 47 is fixedly connected to the first grinding ring 52, the grinding tube 53 and the second grinding ring 55 from top to bottom. The first grinding ring 52 and the second grinding ring 55 both have elastic deformation capability, and the interior of the first grinding ring 52 and the second grinding ring 55 are both hollow. A connecting tube 54 connects the first grinding ring 52 and the second grinding ring 55.

[0033] A first corrugated expansion tube 31 is fixedly connected inside the support column 5, and a second corrugated expansion tube 32 connected to the first corrugated expansion tube 31 and communicating with the channel 11b is fixedly connected to the first corrugated expansion tube 31.

[0034] The stamping head 47 has a through hole 47a that communicates with the first grinding ring 52. A second elastic telescopic tube 56 is fixedly connected in the through hole 47a. A push rod 57 is fixedly connected to the telescopic part of the second elastic telescopic tube 56.

[0035] It should be noted that when the support block 11 moves backward, the first corrugated telescopic tube 31 will be compressed. At the same time, when the support block 11 moves downward, the second corrugated telescopic tube 32 will also be compressed. Then, the first corrugated telescopic tube 31 will connect with the external pump. Next, as the aforementioned stamping head 47 moves downward to stamp the cylindrical shell, the DD motor 51, the first grinding ring 52, the grinding tube 53, the connecting tube 54, the second grinding ring 55, the second elastic telescopic tube 56, and the push rod 57 will move synchronously with the stamping head 47. Then, after the stamping head 47 completes the stamping of the cylindrical shell, the DD motor 51 is controlled to drive the fixed column 46 to rotate. The stamping head 47 and the parts connected to it rotate synchronously with the fixed column 46. Thus, with the stamping... When the stamping head 47 enters the limiting hole 11a, the rotating grinding tube 53 grinds the inner wall of the stamped hole, making the inner wall of the hole on the cylindrical shell smoother and flatter. Then, as the stamping head 47 continues to move downward, the first grinding ring 52 contacts the upper edge of the hole on the cylindrical shell and grinds the upper edge of the hole, removing the burrs at the upper edge of the hole. During this process, both the first grinding ring 52 and the second grinding ring 55 have elastic deformation. The first grinding ring 52 is shaped like an inverted frustum, so the edge of the hole will squeeze the first grinding ring 52 as it moves downward. The first grinding ring 52 will deform, and the air inside the squeezed first grinding ring 52 will enter the second grinding ring 55 through the connecting pipe 54, causing the second grinding ring 55 to expand into a frustum shape. At this time, the second grinding ring 55 is located below the hole on the cylindrical shell. Then, the second hydraulic cylinder 45 is controlled to drive the fixed column 46 to move upward and reset. During this reset process, the second grinding ring 55 will contact the lower edge of the hole on the cylindrical shell and grind it, so that the burrs at the lower edge of the hole are ground off. In this way, the grinding process of the hole on the cylindrical shell is completed. It should be noted that when there are a lot of burrs or flanges on the edge of the hole, the first grinding ring 52 and the second grinding ring 55 are difficult to grind off a lot of burrs. Therefore, a lot of burrs or flanges will still block the connecting wire 16. Thus, by first stamping the cylindrical shell and then polishing the stamped holes using the rotating first polishing ring 52, polishing tube 53, and second polishing ring 55, the processing time of the cylindrical shell can be significantly reduced. This also solves the problem in the prior art where, after stamping the cylindrical shell, there are burrs on the stamped holes. In order to ensure the smoothness and flatness of the holes, it is often necessary to spend extra manpower and polishing equipment to polish the burrs, which is not only troublesome to operate but also increases costs. Meanwhile, during the aforementioned burr removal process, the external pump is controlled to generate an adsorption force in the first corrugated telescopic tube 31 and the second corrugated telescopic tube 32. This causes the removed burrs to pass through the second corrugated telescopic tube 32 and the first corrugated telescopic tube 31 in sequence and enter the external pump for collection. This prevents the removed burrs from falling into the inclined channel 11b through the limiting hole 11a. The burrs would then slide down the inclined channel 11b onto the first electric slide rail 8, which would affect the accuracy of the first electric slider 9 when sliding on the first electric slide rail 8. Meanwhile, some of the air in the first grinding ring 52 after the above-mentioned extrusion will also enter the through hole 47a, and the air in the through hole 47a will enter the second elastic telescopic tube 56, forcing the telescopic part of the second elastic telescopic tube 56 to extend, thereby driving the push rod 57 to move downward, so that the push rod 57 will push the stamped waste piece, thereby preventing the waste piece from getting stuck in the stamping head 47 and affecting the subsequent stamping work of the stamping head 47.
