[0034] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0035] Reference Figure 1 This application provides a punching device. Specifically, the punching device includes two punching members 200. The distance between the two punching members 200 is adjustable. The punching members 200 are used for punching the ends of the outer water-cut trim strip. Because the distance between the two punching members 200 is adjustable, it can be used for punching outer water-cut products 400 with the same end face punching but different length dimensions, and has strong adaptability.
[0036] Among them, such as Figures 2 to 8 As shown, the punching component 200 includes a first positioning member 230, a second positioning member 240, and a punching member 220. The second positioning member 240 is configured to slide, and the punching member 220 is capable of reciprocating motion. A transmission structure is provided between the punching member 220 and the second positioning member 240 so that the second positioning member 240 can press the outer water-cut product 400 positioned on the first positioning member 230 before the punching member 220 approaches the first positioning member 230. The punching member 220 is used for punching the outer water-cut product 400.
[0037] During punching, the end of the outer water-cut product 400 is positioned by the first positioning member 230. During the punching process of the punching member 220 toward the first positioning member 230, because a transmission structure is provided between the punching member 220 and the second positioning member 240, the second positioning member 240 can move toward the first positioning member 230 before the punching member 220 approaches the first positioning member 230, and press the outer water-cut product 400 positioned on the first positioning member 230 to facilitate the punching of the punching member 220 and prevent the punching process from warping and affecting the punching quality.
[0038] Compared to sawing, the punching device of this application does not require manual positioning and clamping during punching, which makes the end punching of the external water-cutting product 400 faster, safer to operate, and eliminates the need for regular saw blade replacement. It has low cost, is easy to maintain, and does not generate debris during the punching process.
[0039] In some embodiments, the punching member 220 is capable of reciprocating along a first direction, and the second positioning member 240 is capable of sliding along a second direction. The first direction and the second direction intersect, and the transmission structure is capable of converting the movement of the punching member 220 along the first direction into the sliding of the second positioning member along the second direction.
[0040] In some embodiments, the first positioning member 230 is provided with a positioning tongue 231, and the outer water-cutting product 400 is engaged on the positioning tongue 231 to complete the positioning of the outer water-cutting product 400.
[0041] In this embodiment, the first direction is vertical and the second direction is horizontal. That is, the punching part 220 reciprocates in the vertical direction. The first positioning part 230 is located below the punching part 220 to facilitate the loading and unloading of the outer water-cut product 400. After the outer water-cut product 400 is positioned on the first positioning part 230, as the punching part 220 moves, the second positioning part 240 is driven by the transmission structure and moves in the horizontal direction toward the first positioning part 230. Before the punching part 220 approaches the first positioning part 230, the second positioning part 240 presses the outer water-cut product 400 against the first positioning part 230 so that the punching part 220 can punch smoothly.
[0042] In some embodiments, such as Figures 2 to 4 As shown, the transmission structure includes a trigger 260, which moves with the punching member 220. The trigger 260 is provided with a first inclined surface 261, and the second positioning member 240 is provided with a second inclined surface 2411 that is adapted to the first inclined surface 261. When the punching member 220 moves toward the first positioning member 230, the first inclined surface 261 can move to abut against the second inclined surface 2411.
[0043] Specifically, such as Figures 7 to 9 As shown, during the movement of the punching member 220 toward the first positioning member 230, the first inclined surface 261 on the trigger member 260 first contacts the second inclined surface 2411 on the second positioning member 240. As the punching member 220 continues to move, under the action of the inclined surfaces, the vertical movement of the trigger member 260 is converted into the horizontal movement of the second positioning member 240, thus enabling the second positioning member 240 to move toward the first positioning member 230. When the second positioning member 240 moves to press the outer water-cut product 400 of the first positioning member 230, as the punching member 220 continues to move, the first inclined surface 261 separates from the second inclined surface 2411, and the side of the trigger member 260 abuts against the second positioning member 240, so that the second positioning member 240 maintains the state of pressing against the outer water-cut product 400. Then the punching member 220 moves into place, and the first positioning member 230 and the punching member 220 cooperate to complete the end punching of the outer water-cut product 400. After the punching is completed, the trigger 260 rises back to its original position along with the punching part 220 and no longer abuts against the second positioning part 240. Therefore, the second positioning part 240 can also return to its original position under the action of external force, which facilitates the next punching.
[0044] To facilitate the return of the second positioning member 240 to its original position, a spring-loaded member 270 is provided between the second positioning member 240 and the first positioning member 230. When the second positioning member 240 moves to press against the outer water-cutting product 400 positioned on the first positioning member 230, the spring-loaded member 270 is compressed. When the pressure on the second positioning member trigger 260 is released, the second positioning member 240 automatically resets under the elastic force of the spring-loaded member 270. In this embodiment, the spring-loaded member 270 is a spring.
[0045] In some embodiments, the punching member 200 further includes a first mounting member 201 and a driving cylinder 210. The driving cylinder 210 is fixed to the first mounting member 201, and the punching member 220 is slidably disposed on the first mounting member 201. The driving cylinder 210 is connected to the punching member 220. Specifically, the first mounting member 201 is vertically arranged, and the driving cylinder 210 is fixed to the top of the first mounting member 201. The driving cylinder 210 is connected to the punching member 220 through a floating joint, and the punching member 220 is slidably disposed on the first mounting member 201, so that the punching position of the punching member 220 is accurate each time.
[0046] Furthermore, the first mounting component 201 is provided with a first guide component 290, and the punching component 220 is slidably connected to the first guide component 290. The first guide component 290 is used to guide the punching component 220 to the first positioning component 230.
[0047] In some embodiments, the first guide member 290 has a T-shaped cross-section, and the punching member 220 is provided with a guide groove adapted to the first guide member 290, that is, the cross-sectional shape of the guide groove is also a T-shaped groove, so that the punching member 220 can slide linearly back and forth. In order to ensure that the movement of the trigger member 260 is accurate each time, a structure for guiding the trigger member 260 can also be provided on the first mounting member 201.
[0048] In some embodiments, such as Figure 4 and Figure 5 As shown, the punching component 200 also includes a second mounting component 202, a first mounting component 201 fixed to the second mounting component 202, a first positioning component 230 fixed to the second mounting component 202, and a second positioning component 240 slidably disposed on the second mounting component 202.
[0049] Specifically, a second guide 280 is provided on the second mounting component 202, and a sliding slider 241 is provided on the second guide 280. The second positioning component 240 is fixed on the slider 241 so that the second positioning component 240 can slide.
[0050] In some embodiments, the second inclined surface 2411 can be disposed on the second positioning member 240, or on the slider 241, which can also drive the second positioning member 240 to move.
[0051] In some embodiments, the punching member 200 further includes a guide groove 250 for discharging punching waste. Specifically, one end of the guide groove 250 is close to the side of the first positioning member 230 that contacts the punching member 220, and the other end of the guide groove 250 can extend to the waste box. After the punching member 220 and the first positioning member 230 cooperate to complete the punching of the external water-cut product 400, the waste generated by punching falls into the guide groove 250 and is guided to the waste box through the guide groove 250.
[0052] like Figure 11 and Figure 12 As shown, the punching device also includes a sliding platform 100 and a sliding member 120 that can slide on the sliding platform 100. The punching member 200 is fixed to the sliding member 120, and the sliding member 120 is connected to the sliding platform 100 by fasteners.
[0053] The sliding platform 100 has guide rails 111 on both sides along its length, and the sliding member 120 has a sliding groove 121. When the sliding member 120 is engaged with the sliding platform 100, the guide rails 111 are engaged in the sliding groove 121, so that the sliding member 120 will not detach from the sliding platform 100 during the sliding process. To allow the sliding member 120 to be fixed at any position on the sliding platform 100, fasteners are used to lock the sliding member 120 to the sliding platform 100. When both punching members 200 are fixed to the sliding platform 100 by the sliding member 120, the distance between the two punching members 200 can be adjusted after the fasteners are released.
[0054] In some specific embodiments, such as Figure 12 As shown, the sliding member 120 is provided with an elongated groove 122, which is located on the outer side of the sliding member 120. The sliding platform 100 has a plurality of first screw holes 112 spaced apart along the sliding direction of the sliding member 120. When the sliding member 120 engages with the sliding platform 100, the screw holes are positioned on the movement path of the elongated groove 122. Fasteners are threaded through the elongated groove 122 and connected to the first screw holes 112 to restrict the sliding of the sliding member 120. This makes the position of the sliding member 120 on the sliding platform 100 adjustable.
[0055] In some embodiments, the punching device further includes a top-loading assembly 300, which is located near the punching members 200 and between the two punching members 200. Each punching member 200 is equipped with a top-loading assembly 300. Positioning the top-loading assembly 300 near the punching member 200 can push away the outer water-cut product 400 that is stuck to the first positioning member 230 due to punching, facilitating subsequent material removal. In some embodiments, the material removal assembly can be mounted on the second mounting base of the punching member 200, and the top-loading assembly 300 can also be adjusted when the punching member 200 is adjusted.
[0056] Specifically, such as Figure 10 As shown, the top-feeding assembly 300 includes a mounting base, a cylinder 320, and a top-feeding block. The mounting base is fixed to the sliding platform 100 or the second mounting member 202 by bolts. When the top-feeding assembly 300 is installed on the sliding platform 100, multiple sets of spaced second screw holes 113 are provided on the top surface of the sliding platform 100 so that the mounting base can be installed at any position on the top surface of the sliding platform 100 for easy adjustment. The top-feeding block 310 is fixed to the cylinder 320 rod of the cylinder 320. The cylinder 320 drives the top-feeding block 310 to move, thereby pushing away the external water-cutting product 400 that is stuck in the first positioning member 230.
[0057] Compared to saw blade machines, this application has a simple structure, convenient electrical control, and does not require expensive saw blades and servo motors. The manufacturing cost of the entire device is low, and the later maintenance and repair are also convenient. It is driven by a hydraulic cylinder for punching, which is fast and does not produce debris.
[0058] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
