Description

Technical Field

[0001] This invention relates to the field of pot body processing equipment technology, and in particular to a pot body edge punching device. Background Technology

[0002] Stamping is a forming process that uses a press and upper die to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. As is well known, pot bodies are typically processed using stamping, such as... Figure 1 The waste material on the edge of the stamped pot body shown in the figure usually needs to be punched off. Due to the punching process, there are burrs on the edge of the stamped pot body, which need to be polished in subsequent processing. In the existing stamped pot body production process, the waste material on the edge of the pot body is first punched off by punching equipment, and then the operator operates a polishing machine to polish the burrs on the edge of the stamped pot body. The above pot body processing is complicated, resulting in low pot body production efficiency, and requires the investment of at least two machines and a lot of human resources. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes a pot edge punching device.

[0004] The technical solution of this invention is implemented as follows:

[0005] A pot edge punching device includes a base, a rotating block rotatably connected to the upper end of the base, and a groove with an upper opening on the upper end of the rotating block. A portal frame is provided on the base above the rotating block, and a punching cylinder is fixedly mounted on the upper end of the portal frame. The telescopic end of the punching cylinder is vertically downward and fixedly mounted with a punching sleeve located inside the portal frame. A punching blade is provided at the lower opening of the punching sleeve, and the punching blade is used to punch waste material at the edge of the pot. A clamping assembly is provided inside the punching sleeve; when the punching sleeve punches downwards at the edge of the pot, the clamping assembly... The component is first pressed against the edge of the pot body. When the punching sleeve moves upward to the upper position, the pressing component moves upward away from the edge of the pot body. The inner wall of the punching sleeve is provided with a grinding component, which is used to grind the edge of the pot body after punching. The base is provided with a transmission component on the outside of the rotating block. After the punching sleeve punches the edge of the pot body, as the punching sleeve moves downward, the transmission component drives the rotating block to rotate the pot body. When the punching sleeve moves to the lower position, it moves upward to reset. The transmission component drives the rotating block to rotate the pot body in the opposite direction.

[0006] Furthermore, the grinding assembly includes multiple grinding blocks. The inner wall of the punching sleeve is evenly spaced circumferentially with multiple radial slots corresponding to the grinding blocks. Two radial sliding rods are fixedly installed in each radial slot. The grinding blocks are located within the radial slots and are slidably connected to the radial sliding rods along the radial direction of the punching sleeve. Each radial sliding rod is fitted with a first spring for forcing the grinding block to press against the grinding assembly. The grinding blocks have an upper grinding slope, a lower grinding slope, and a... on the side facing the pressing assembly. The vertical grinding surface is located between the upper grinding slope and the lower grinding slope; the lower grinding slope is used to grind the upper end of the edge of the punched pot body, the vertical grinding surface is used to grind the outer side of the edge of the punched pot body, and the upper grinding slope is used to grind the lower end of the edge of the punched pot body; when the lower grinding slope abuts against the upper end of the edge of the pot body, or the upper grinding slope abuts against the lower end of the edge of the pot body, as the punching sleeve moves in the vertical direction, the grinding block slides along the radial slide rod in the radial groove.

[0007] Furthermore, during the downward cutting of the pot body edge by the cutting sleeve, the cutting blade first cuts the waste material on the edge of the pot body downwards. As the cutting sleeve continues to move downwards, the transmission component drives the rotating block to rotate the pot body. First, the lower grinding bevel grinds the upper end of the rotating pot body edge, then the vertical grinding bevel grinds the outer side of the rotating pot body edge, and then the upper grinding bevel grinds the lower end of the rotating pot body edge. When the cutting sleeve moves to the lower position, it moves upwards to reset. The transmission component drives the rotating block to rotate the pot body in the opposite direction. First, the upper grinding bevel grinds the lower end of the rotating pot body edge again, then the vertical grinding bevel grinds the outer side of the rotating pot body edge again, and then the lower grinding bevel grinds the upper end of the rotating pot body edge again.

[0008] Furthermore, the clamping assembly includes a clamping block located within the punching sleeve. A pressure block is rotatably connected to the lower end of the clamping block, which is used to press the edge of the pot body downwards against the upper end of the rotating block. A protrusion is threadedly fixed to the lower end of the pressure block, which extends out of the pot body and supports it. A limiting sliding hole is provided in the middle of the clamping block, pressure block, and protrusion. A downwardly extending shaft is fixed to the top of the punching sleeve, and the lower end of the shaft extends downwards into the limiting sliding hole and is fixedly provided with a limiting protrusion. A guide rod extending vertically upwards through the top of the punching sleeve and the portal frame is fixed to the upper end of the clamping block on both sides of the shaft. A second spring is sleeved on the guide rod, located between the clamping block and the top of the punching sleeve, to force the clamping block to move downwards. When the punching sleeve moves upwards to the upper position, the punching sleeve drives the clamping block, pressure block, and protrusion upwards away from the pot body via the limiting protrusion on the shaft.

[0009] Furthermore, the lower end face of the pressure block is provided with a plurality of first radial grooves evenly spaced along the circumference of the pressure block, and the top surface of each first radial groove is provided with a second radial groove; a pressure rod is slidably connected in each first radial groove along the radial direction of the pressure block, the pressure rod is used to press the edge of the pot body downwards against the upper end of the rotating block, so as to prevent the edge of the pot body from lifting upwards when the punching sleeve punches downwards; the protrusion is used to restrict the pressure rod in the first radial groove; each pressure rod has a protruding plate extending into the corresponding second radial groove on its side; each first radial groove is provided with a third spring for forcing the pressure rod to extend outwards, when the end of the pressure rod is fully extended out of the first radial groove, the protruding plate abuts against the distal end of the second radial groove; the preload of the third spring is less than the preload of the first spring; each end of the pressure rod extending out of the first radial groove is provided with a relief slope, when the lower grinding slope contacts the relief slope, as the grinding block moves downwards, the pressure rod moves into the first radial groove and compresses the third spring.

[0010] Furthermore, the transmission assembly includes a transmission ring sleeved on the rotating block. The inner wall of the transmission ring has an inner transmission thread, and the outer side of the rotating block has an outer transmission thread connected to the inner transmission thread. The base has a vertical sliding hole, and the lower end of the transmission ring has a first sliding rod extending downward and slidably connected in the vertical sliding hole. A fourth spring is sleeved on the first sliding rod between the transmission ring and the base. The fourth spring is used to force the transmission ring to move upward. When the transmission ring moves vertically, the inner transmission thread and the outer transmission thread cooperate to drive the rotating block to rotate. The side wall of the portal frame has an upper baffle, and the outer side of the transmission ring has a lower baffle. When the transmission ring is in the upper position, the lower baffle abuts against the lower side of the upper baffle. After the punching sleeve punches the edge of the pot body, as the punching sleeve moves downward, the lower end of the punching sleeve abuts against the transmission ring and drives the transmission ring to move downward. When the punching sleeve moves to the lower position, it returns to its original position as the punching sleeve moves upward. The transmission ring moves upward under the action of the fourth spring.

[0011] The upper end of the transmission ring is provided with an upwardly extending convex ring. When the transmission ring is in the upper position, the convex ring abuts against the lower end of the edge of the pot body. At the moment when the punching sleeve punches the edge of the pot body downward, due to inertia, the transmission ring remains in the upper position, thereby driving the convex ring to abut against the lower end of the edge of the pot body, so as to prevent the edge of the pot body from bending and deforming downward due to the punching of the punching sleeve.

[0012] Furthermore, the base is provided with a first rotating hole, the lower end of the rotating block is provided with a first rotating shaft extending into the first rotating hole, and a first bearing is provided between the first rotating hole and the first rotating shaft; the lower end of the pressing block is provided with a second rotating hole, the upper end of the pressing block is provided with a second rotating shaft extending into the second rotating hole, and a second bearing is provided between the second rotating hole and the second rotating shaft.

[0013] The beneficial effects of this invention are as follows: When using this pot edge punching device, simply place the pot body into the groove. The fit between the pot body and the groove allows for automatic centering of the pot body, causing the edge of the pot body to abut against the upper end of the rotating block. Then, control the extension of the punching cylinder to drive the punching sleeve downwards. During the downward movement of the punching sleeve, the clamping component first presses the pot body against the upper end of the brick. As the punching sleeve continues to move downwards, the punching blade at the lower end of the punching sleeve punches the waste material at the edge of the pot body. Next, the lower end of the punching sleeve abuts against the transmission ring, pushing the transmission ring downwards. The transmission ring drives the pot body to rotate via the rotating block. Subsequently, the grinding component moves downwards to perform a second grinding on the rotated edge of the pot body after punching. The process involves a single grinding step. When the punching sleeve moves to its lower position and then moves upward to reset, the transmission ring, under the action of the fourth spring, drives the pot body to rotate in the opposite direction via the rotating block. At this time, the grinding component moves upward to perform a second grinding on the rotating edge of the pot body after punching. When the punching sleeve moves upward to its upper position, the pressing component moves upward away from the pot body, at which point the pot body can be removed. This invention has a simple structure, requiring only the extension and retraction of the punching cylinder to complete the punching and two grinding steps on the edge of the pot body, greatly improving the processing efficiency of the pot body. The pressure rod prevents the edge of the pot body from tilting upward when the punching sleeve punches downward. The convex ring prevents the edge of the pot body from bending and deforming downward due to the punching of the punching sleeve. Attached Figure Description

[0025] like Figure 1-9 As shown, a pot edge punching device of the present invention includes a base 1, a rotating block 2 rotatably connected to the upper end of the base 1. In this embodiment, the base 1 has a first rotating hole 1a, and the lower end of the rotating block 2 has a first rotating shaft 2a extending into the first rotating hole 1a. A first bearing 3 is provided between the first rotating hole 1a and the first rotating shaft 2a. The upper end of the rotating block 2 has a groove 2b with an upper opening. A portal frame 4 is provided on the base 1 above the rotating block 2. A punching cylinder 5 is fixedly provided at the upper end of the portal frame 4. The telescopic end of the punching cylinder 5 is vertically downward and fixedly provided with a punching sleeve 6 located inside the portal frame 4. A punching blade 6a is provided at the lower opening of the punching sleeve 6. The punching blade 6a is used to punch the waste material at the edge 11a of the pot. The punching sleeve 6 is equipped with a clamping component. When the punching sleeve 6 punches the edge 11a of the pot body downwards, the clamping component first clamps onto the edge 11a of the pot body. When the punching sleeve 6 moves upwards to the upper position, the clamping component moves upwards away from the edge 11a of the pot body. The inner wall of the punching sleeve 6 is equipped with a grinding component, which is used to grind the edge 11a of the pot body after punching. The base 1 is equipped with a transmission component on the outside of the rotating block 2. After the punching sleeve 6 punches the edge 11a of the pot body, as the punching sleeve 6 moves downwards, the transmission component drives the rotating block 2 to rotate the pot body 11. When the punching sleeve 6 moves to the lower position, as the punching sleeve 6 moves upwards to reset, the transmission component drives the rotating block 2 to rotate the pot body 11 in the opposite direction.

[0026] In this embodiment, the grinding assembly includes eight grinding blocks 7. The inner wall of the punching sleeve 6 is provided with eight radial slots 6a, each corresponding to one of the grinding blocks 7, evenly spaced circumferentially. Two radial slide rods 8 are fixedly installed in each radial slot 6a. The grinding blocks 7 are located in the radial slots 6a and are slidably connected to the radial slide rods 8 along the radial direction of the punching sleeve 6. A first spring 9 is sleeved on each radial slide rod 8 to force the grinding blocks 7 to press against the grinding assembly. The grinding blocks 7 are provided with an upper grinding inclined surface 7a, a lower grinding inclined surface 7b, and a grinding inclined surface 7b on the side facing the pressing assembly. The vertical grinding surface 7c is between surface 7a and the lower grinding slope 7b; the lower grinding slope 7b is used to grind the upper end of the punched pot body edge 11a, the vertical grinding surface 7c is used to grind the outer side of the punched pot body edge 11a, and the upper grinding slope 7a is used to grind the lower end of the punched pot body edge 11a; when the lower grinding slope 7b abuts against the upper end of the pot body edge 11a, or the upper grinding slope 7a abuts against the lower end of the pot body edge 11a, as the punching sleeve 6 moves in the vertical direction, the grinding block 7 slides along the radial slide bar 8 in the radial groove 6a.

[0027] In this embodiment, the clamping assembly includes a clamping block 10 located inside the punching sleeve 6. A clamping block 12 is rotatably connected to the lower end of the clamping block 10. A second rotating hole 10a is provided at the lower end of the clamping block 10. A second rotating shaft 12a extending into the second rotating hole 10a is provided at the upper end of the clamping block 12. A second bearing 13 is provided between the second rotating hole 10a and the second rotating shaft 12a. The clamping block 12 is used to press the edge 11a of the pot body downwards against the upper end of the rotating block 2. A protrusion 14 is threadedly fixed to the lower end of the clamping block 12. The protrusion 14 extends out of the pot body 11 and supports the pot body 11. A limiting sliding hole 100 is provided in the middle of the clamping block 10, the clamping block 12, and the protrusion 14. The top of the punching sleeve 6 is fixedly provided with a downwardly extending shaft 15, the lower end of which extends downward into the limiting sliding hole 100 and is fixedly provided with a limiting protrusion 15a; the upper end of the pressing block 10 is fixedly provided with a vertically upward extending guide rod 16 on both sides of the shaft 15, which passes through the top of the punching sleeve 6 and the portal frame 4; a second spring 17 is sleeved on the guide rod 16, and the second spring 17 is located between the pressing block 10 and the top of the punching sleeve 6 to force the pressing block 10 to move downward; when the punching sleeve 6 moves upward to the upper position, the punching sleeve 6 drives the pressing block 10, the pressing block 12, and the protrusion 14 to move upward away from the pot body 11 through the limiting protrusion 15a on the shaft 15.

[0028] In this embodiment, the lower end face of the pressure block 12 is provided with eight first radial grooves 12b evenly spaced along the circumference of the pressure block 12, and the top surface of each first radial groove 12b is provided with a second radial groove 12c; each first radial groove 12b is slidably connected with a pressure rod 18 along the radial direction of the pressure block 12, the pressure rod 18 is used to press the edge 11a of the pot body downwards against the upper end of the rotating block 2, so as to prevent the edge 11a of the pot body from tilting upwards when the punching sleeve 6 punches downwards; the protrusion 14 is used to restrict the pressure rod 18 within the first radial groove 12b; each pressure rod 18 has a side surface that extends into the corresponding second radial groove. The slide groove 12c contains a protruding plate 19; each first radial slide groove 12b is provided with a third spring 20 for forcing the pressure rod 18 to extend outward. When the end of the pressure rod 18 is fully extended from the first radial slide groove 12b, the protruding plate 19 abuts against the distal end of the second radial slide groove 12c; the preload of the third spring 20 is less than the preload of the first spring 9; each end of the pressure rod 18 extending out of the first radial slide groove 12b is provided with a relief slope 18a. When the lower grinding slope 7b contacts the relief slope 18a, as the grinding block 7 moves downward, the pressure rod 18 moves into the first radial slide groove 12b and compresses the third spring 20.

[0029] In this embodiment, the transmission assembly includes a transmission ring 21 sleeved on the rotating block 2. The inner sidewall of the transmission ring 21 is provided with an inner transmission thread (not shown in the figure), and the outer side of the rotating block 2 is provided with an outer transmission thread connected to the inner transmission thread (not shown in the figure). The base 1 is provided with a vertical sliding hole 1b. The lower end of the transmission ring 21 is provided with a first sliding rod 22 extending downward and slidably connected in the vertical sliding hole 1b. A fourth spring 23 is sleeved on the first sliding rod 22 between the transmission ring 21 and the base 1. The fourth spring 23 is used to force the transmission ring 21 to move upward. When the transmission ring 21 moves in the vertical direction, the inner transmission thread and the outer transmission thread cooperate to drive the rotating block 2 to rotate. The sidewall of the portal frame 4 is provided with an upper baffle 24, and the outer side of the transmission ring 21 is provided with a lower baffle 25. When 21 is in the upper position, the lower baffle 25 abuts against the lower side of the upper baffle 24; after the punching sleeve 6 punches the edge 11a of the pot body, as the punching sleeve 6 moves downward, the lower end of the punching sleeve 6 abuts against the transmission ring 21 and drives the transmission ring 21 to move downward. When the punching sleeve 6 moves to the lower position, it moves upward and resets, and the transmission ring 21 moves upward under the action of the fourth spring 23; the upper end of the transmission ring 21 is provided with an upwardly extending convex ring 21a. When the transmission ring 21 is in the upper position, the convex ring 21a abuts against the lower end of the edge 11a of the pot body; at the instant when the punching sleeve 6 punches the edge 11a of the pot body downward, due to inertia, the transmission ring 21 remains in the upper position and thus drives the convex ring 21a to abut against the lower end of the edge 11a of the pot body, so as to prevent the edge 11a of the pot body from bending and deforming downward due to the punching of the punching sleeve 6.

[0030] In this embodiment, the pot body edge punching device only requires placing the pot body 11 into the groove 2b during use. The fit between the pot body 11 and the groove 2b enables automatic centering of the pot body 11, causing the pot body edge 11a to abut against the upper end of the rotating block 2. Then, the pressing cylinder 5 extends, driving the punching sleeve 6 downwards. During the downward movement of the punching sleeve 6, the protrusion 14 in the pressing assembly extends into the pot body to support it. Simultaneously, the eight pressing rods 18 press against the upper side of the pot body edge 11a. Since the transmission ring 21 is in the upper position under the action of the fourth spring 23, the protrusion... The upper end of ring 21a abuts against the lower side of the pot body edge 11a. As the punching sleeve 6 continues to move downward, the punching sleeve 6, through the compression of the second spring 17, presses the pot body edge more firmly against the upper end of the rotating block 2 via the pressing block 10, pressing block 12, and pressing rod 18. At the same time, the punching blade 6a at the lower end of the punching sleeve 6 punches the waste material on the edge of the pot body. At the instant the punching sleeve 6 punches the edge of the pot body 11a, the protrusion 14 and the pressing rod 18 remain stationary, thereby preventing deformation of the pot body edge. After the pot body edge is punched, as the punching sleeve 6 continues to move downward, the lower end of the punching sleeve 6 abuts against the lower side of the rotating block 2. When the transmission ring 21 is pressed against the transmission ring 21 and pushed downward, the transmission ring 21 rotates downward through the engagement of the inner and outer transmission threads, driving the rotating block 2 to rotate the pot body. First, the lower grinding bevel 7b grinds the upper end of the rotating pot body edge, then the vertical grinding surface 7c grinds the outer side of the rotating pot body edge 11a, and then the upper grinding bevel 7a grinds the lower end of the rotating pot body edge. When the punching sleeve 6 moves upward to reset after reaching the lower end position, the transmission ring 21, under the action of the fourth spring 23, drives the pot body to rotate in the opposite direction through the rotating block 2. At this point, the upper grinding bevel 7a is used to grind the lower end of the rotating pot body edge again, then the vertical grinding surface 7c is used to grind the outer side of the rotating pot body edge again, and then the lower grinding bevel 7b is used to grind the upper end of the rotating pot body edge again. When the punching sleeve 6 moves upward to the upper position, the punching sleeve 6 drives the clamping block 10, the clamping block 12, and the protrusion 14 to move upward away from the pot body 11 through the shaft 15 and the limiting protrusion 15a. At the same time, the transmission ring 21 is in the upper position, and the lower baffle 25 abuts against the lower side of the upper baffle 24. At this point, the pot body can be removed.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
