[0039] See also Figures 1 to 10The embodiment of the present application provides a punching device, comprising: a base 100, having a positioning hole 101; a first driving assembly 200, arranged on the base 100 and located above the positioning hole 101; a tool 300, arranged at the output end of the first driving assembly 200; and a scraper assembly 400, movably arranged on the first driving assembly 200 and arranged around the periphery of the tool 300; the first driving assembly 200 drives the tool 300 to approach and cut the workpiece to be punched placed at the positioning hole 101, the scraper assembly 400 abuts against the workpiece to be punched and moves in a direction approaching the first driving assembly 200, the first driving assembly 200 drives the tool 300 away from the positioning hole 101, and the scraper assembly 400 moves in a direction away from the first driving assembly 200 to eject the punching waste in the tool 300 and scrape off the residual waste on the surface of the tool 300.
[0040] In this embodiment, the drilling operation of the workpiece to be punched is realized by the coordinated cooperation of the positioning hole 101 on the base 100, the first driving assembly 200 and the tool 300, which is simple to operate and is conducive to batch drilling operations; at the same time, a movable scraper assembly 400 is provided on the output end of the first driving assembly 200, so that the relative position relationship between the scraper assembly 400 and the tool 300 during the drilling operation can be changed through the coordinated cooperation with the first driving assembly 200, so that when the tool 300 cuts the workpiece to be punched, it can move toward the first driving assembly 200 to Avoid punching waste, improve the smoothness of punching, and, after the tool 300 leaves the workpiece to be punched, the punching waste inside the tool 300 can be ejected, while the residual waste on the cutting surface of the tool 300 can be scraped and cleaned, and the inside and surface of the tool 300 can be double cleaned while punching, effectively shortening the punching time between the two times, improving the continuous production efficiency of the punching device, and the cleaning effect of the tool 300 is good, will not affect the cutting path and the smoothness of the hole wall of the next punching operation, the punching accuracy is high, the hole quality is excellent, and the product quality is good.
[0041] Specifically, the punching device is configured as a combined component including at least a base 100, a first drive assembly 200, a tool 300 and a scraper assembly 400. The base 100 can be a nearly rectangular box-shaped structure, the top of which is a working platform with a suspended support structure, and the periphery is a supporting side plate. The suspended support structure is arranged above the working platform to provide a height space in a direction perpendicular to the working platform; a positioning hole 101 is arranged on the working platform, and the positioning hole 101 can be an annular convex hole structure that protrudes upward and has a middle through hole, and the area of the protruding periphery can at least completely cover the area of the abutting end of the scraper assembly 400 to achieve abutment with the scraper assembly 400. The size of the middle through hole can be slightly larger than the size of the tool 300 so that the tool 300 can pass through to achieve the punching operation of the workpiece to be punched placed on the positioning hole 101. The first drive assembly 200 can be a drive motor, which can be connected to the suspended support structure of the base 100 by fasteners such as screws / bolts, so that the first drive assembly 200 is located above the positioning hole 101; of course, in order to further enhance the stability and reliability of the connection between the first drive assembly 200 and the base 100, and enhance the strength of the connection between the first drive assembly 200 and the base 100, reinforcing plates can be provided on both sides of the suspended support structure. The tool 300 can be a cylindrical tool 300 with a hollow hole. The cross-sectional shape of the tool 300 can be various, such as circular, square, prismatic, hexagonal, elliptical, irregular polygonal or irregular arc-shaped, etc. The specific shape of the tool 300 is not limited here, and the operator can choose according to needs; one end of the tool 300 can be connected to the output end of the first drive assembly 200 by welding or the like, and the other end is suspended and has a blade portion, which can cut the designated position of the workpiece to be punched. The scraper assembly 400 can be an inner and outer double-layer cylindrical scraper structure, wherein the outer scraper can be used to scrape off metal debris adhered to the outer wall of the tool 300, and the inner scraper can be used to scrape off metal debris adhered to the inner wall of the tool 300 and push out the punching waste inside the tool 300. In this way, the punching waste can be removed during the punching process, avoiding the need to subsequently remove the punching waste through a dedicated material removal tool, streamlining the cleaning process of the tool 300, shortening the cleaning time, and improving the efficiency of continuous punching; and, during the punching process, the metal debris attached to the surface of the tool 300 can be scraped off and cleaned, avoiding the cutting path of the tool 300 being affected by metal particles adhering to the surface of the tool 300 during the next punching, thereby improving the punching accuracy of continuous punching, and avoiding the smoothness of the hole wall of the subsequent hole being affected by metal particles adhering to the surface of the tool 300 during the next punching, thereby improving the smoothness of the hole wall of continuous punching, improving the hole quality, and improving the processing quality of the workpiece to be punched.
[0042] From the above, the punching process of the punching device provided by the present application is as follows: first, the first driving component 200 drives the tool 300 and the scraper component 400 to approach the workpiece to be punched placed at the positioning hole 101. At this time, the scraper component 400 first contacts the workpiece to be punched to limit the space of the workpiece to be punched, and fixes the workpiece to be punched on the specified position of the base 100 to prevent it from moving, so as to facilitate the subsequent tool 300 to perform the cutting action and improve the punching accuracy; then, the tool 300 is continued to be moved in the direction close to the workpiece to be punched through the first driving component 200 until the tool 300 extends into the positioning hole 101 to cut off the workpiece to be punched in its moving direction and obtain a hole. At this time, the scraper component 400 moves back in the direction of the first driving component 200 under the pressure of the workpiece to be punched. The tool 300 moves in the direction of the workpiece to be punched, while the tool 300 continues to move toward the direction close to the workpiece to be punched, and forms a relative movement with the scraper assembly 400. In this way, the tool 300 can not only cut off the designated area of the workpiece to be punched and obtain a hole, but also put the scraper assembly 400 in an energy storage state, in preparation for the subsequent ejection of the punching waste and the scraping of the residual waste; then, the tool 300 and the scraper assembly 400 are moved away from the workpiece to be punched by the first drive assembly 200. At this time, the tool 300 successively escapes from the positioning hole 101 and the hole of the workpiece to be punched, and the scraper assembly 400 moves in the direction away from the first drive assembly 200 under the action of its own gravity, and while ejecting the punching waste, it scrapes and cleans the residual waste on the surface of the tool 300 to prepare for the next punching. In this way, continuous punching of the punching device can be achieved.
[0043] It is understandable that the punching device provided in the present application is not only applicable to the punching operation of special-shaped holes in automobile chassis, but also to the punching operation of standard holes in automobiles. Of course, it is also applicable to the punching operation of standard holes or special-shaped holes in other parts, with rich usage scenarios and a wide range of applications.
[0044] like Figure 2 and Figure 3 As shown, in a possible embodiment, a first limiting groove 301 is provided on the tool 300, and the first limiting groove 301 extends along the cutting direction of the tool 300. The scraper assembly 400 includes a first connecting member 410, a first scraper 420 connected to the bottom of the first connecting member 410, a second connecting member 430 and a second scraper 440 connected to the bottom of the second connecting member 430. The first connecting member 410 is provided with a tool avoidance hole 401, and the tool 300 is movably inserted in the tool avoidance hole 401. The first connecting member 410 and the first scraper 420 are located on the outside of the tool 300, and the second connecting member 430 is connected to the inner side of the first connecting member 410 through the first limiting groove 301. The second connecting member 430 and the second scraper 440 are located on the inner side of the tool 300.
[0045] In this embodiment, the specific configuration of the scraper assembly 400 is optimized. Specifically, the scraper assembly 400 is configured as a composite component including at least a first connecting member 410, a first scraper 420, a second connecting member 430 and a second scraper 440. The first connecting member 410 can be a circular plate-shaped structure, the second connecting member 430 can be a circular plate-shaped structure, and the second connecting member 430 can be connected to the inner side of the first connecting member 410 through a transverse connecting rod to form a double circle structure; in this way, when the scraper assembly 400 is assembled to the tool 300, the first connecting member 410 is arranged around the outer periphery of the tool 300, the second connecting member 430 is received inside the tool 300 and is connected to the inner periphery of the tool 300, and the transverse connecting rod passes through the first limiting groove 301 to abut against the workpiece to be punched at the second scraper 440, and drive the second connecting member 430 to approach. When the first drive assembly 200 moves in the direction of the punching, it can be driven by the transverse connecting rod, thereby driving the first connecting member 410 and the first scraper 420 to move in the direction close to the first drive assembly 200, realizing the relative movement of the tool 300 and the scraper assembly 400, completing the cutting of the workpiece to be punched by the tool 300 and the energy storage state of the scraper assembly 400; and, when the tool 300 is away from the workpiece to be punched, the scraper assembly 400 moves in the direction away from the first drive assembly 200 under the action of its own gravity, realizing the ejection of the punching waste inside the tool 300 by the second scraper 440, and the cleaning of the metal chips on the outer wall surface of the tool 300 by the first scraper 420 and the cleaning of the metal chips on the inner wall surface of the tool 300 by the second scraper 440, so that the punching and cleaning efficiency is high. The first scraper 420 may be a cylindrical structure, and a brush layer may be provided on the inner side thereof to scrape off the metal debris remaining on the outer wall surface of the tool 300; the second scraper 440 may be a cylindrical structure, and a brush layer may be provided on the outer side thereof to scrape off the metal debris remaining on the inner wall surface of the tool 300, thereby cleaning the inner wall surface of the tool 300 to prepare for the next drilling operation. The scraper assembly 400 provided in this example has a simple structure and a strong synergistic effect with the tool 300, and can simultaneously realize the cutting of the workpiece to be punched, the cleaning of the punching waste in the tool 300, and the cleaning of the metal debris remaining adhering to the surface of the tool 300, and has a stronger integrity.
[0046] It should be explained that a gap is formed between the first scraper 420 and the second scraper 440 , and the gap forms an annular channel, and the cutter 300 is movably inserted in the annular channel.
[0047] In one example, a plurality of first limiting grooves 301 may be provided on the cutter 300, and the plurality of first limiting grooves 301 are spaced and distributed at intervals on the periphery of the cutter 300. A plurality of transverse connecting rods connecting the first connecting member 410 and the second connecting member 430 may be provided, and one transverse connecting rod passes through one first limiting groove 301, so as to improve the transmission uniformity of the second connecting member 430 and the first connecting member 410, so that the first connecting member 410 and the second connecting member 430 in the peripheral direction can move synchronously, thereby improving the smoothness and silkiness of the movement of the cutter 300 and the scraper assembly 400, and improving the overall performance of the punching device.
[0048] like Figure 2 and Figure 3 As shown, in a possible implementation, the scraper assembly 400 further includes a first guide member 450 extending along the cutting direction of the tool 300 , one end of the first guide member 450 is movably disposed on the first driving assembly 200 , and the other end is disposed on the first connecting member 410 .
[0049] In this embodiment, the specific configuration of the scraper assembly 400 is further optimized. Specifically, the scraper assembly 400 is configured as a composite component including at least a first connecting member 410, a first scraper 420, a second connecting member 430, a second scraper 440 and a first guide member 450. A connecting end plate is provided on the output end of the first drive assembly 200, and a sliding hole is provided on the connecting end plate. The first guide member 450 can be a cylindrical rod, one end of which is movably inserted into the sliding hole, and the other end can be fixedly connected to the first connecting member 410 by welding or snap connection. In this way, when the scraper assembly 400 moves toward the first drive assembly 200, it can be guided to improve the movement accuracy of the scraper assembly 400, facilitate the subsequent accurate removal of metal debris on the tool 300, and improve the cleaning effect. The movement trajectory of the scraper assembly 400 provided in this example is accurate and reliable, and the cleaning effect on the surface of the tool 300 is better.
[0050] In one example, a plurality of first guide members 450 may be provided, and the plurality of first guide members 450 are spaced apart and distributed around the periphery of the tool 300. In this way, the guiding function of the scraper assembly 400 and the first drive assembly 200 may be improved at least in the peripheral direction, further improving the movement accuracy of the scraper assembly 400, and improving the smoothness of movement and the cleaning effect.
[0051] like Figure 3 As shown, in a possible implementation manner, the scraper assembly 400 further includes a first elastic member 460 , and the first elastic member 460 is disposed between the first driving assembly 200 and the first connecting member 410 .
[0052] In this embodiment, the specific configuration of the scraper assembly 400 is further optimized. Specifically, the scraper assembly 400 is configured as a composite component including at least a first connecting member 410, a first scraper 420, a second connecting member 430, a second scraper 440, a first guide member 450 and a first elastic member 460. The first elastic member 460 can be a spring, which is sleeved on the first guide member 450, and the two ends of which respectively abut against the connecting end plate of the first drive assembly 200 and the first connecting member 410. In this way, when the scraper assembly 400 moves toward the first drive assembly 200, the first connecting member 410 and the first drive assembly 200 are connected. Elastic potential energy is accumulated between the moving components 200, and when the scraper component 400 moves away from the first driving component 200, kinetic potential energy is provided to the first connecting member 410, the first scraper 420, the second connecting member 430 and the second scraper 440. The kinetic potential energy can increase the ejection force of the second scraper 440 and the second connecting member 430 on the punching waste inside the tool 300, and increase the scraping and cleaning speed of the first scraper 420 and the second scraper 440 on the outer wall and the inner wall of the tool 300, thereby improving the cleaning efficiency and improving the cleaning effect.
[0053] In one example, a plurality of first elastic members 460 may be provided, with one first elastic member 460 being sleeved outside a first guide member 450 to at least increase the elastic potential energy that can be accumulated between the first connecting member 410 and the first driving assembly 200 in quantity, thereby further improving the waste cleaning effect.
[0054] like Figure 1 , Figure 6 , Figure 8 and Fig.10 As shown, in a possible implementation, the base 100 includes a workbench 110 and a first bracket 120 mounted on the workbench 110 , the positioning hole 101 is disposed on the workbench 110 , and the first driving assembly 200 is disposed on the first bracket 120 .
[0055] In this embodiment, the specific configuration of the base 100 is optimized. Specifically, the base 100 is configured as a combined component including at least a workbench 110 and a first bracket 120. The workbench 110 may be a nearly rectangular box-shaped structure, and the positioning hole 101 is arranged on the top of the workbench. The first bracket 120 may be an inverted U-shaped frame, and may be configured as a combined component including two support arms and a connecting beam. The two support arms are respectively protruding on opposite sides of the workbench 110, and the two ends of the connecting beam are respectively connected to the two support arms and are located above the positioning hole 101.
