DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0039] Example 1

[0040] like Figure 1 — Figure 8 As shown, a movable vertical punching structure for a manifold of the present invention includes a base plate 100 , a loading assembly 200 , a positioning assembly 400 , a disengagement assembly 500 , a pressing assembly 600 , a pre-punching knife 610 and an expanding punching knife 620 .

[0041] In the present invention, a positioning groove 320 corresponding to the positioning assembly 400 is provided on the side of the collecting pipe 300; the movable vertical punch structure of the present invention also includes a control system (not marked in the figure) for controlling the positioning assembly 400, the disengagement assembly 500, the pressing assembly 600 and the pushing cylinder body.

[0042] The loading assembly 200 is arranged on the bottom plate 100, and the loading assembly 200 can move horizontally relative to the bottom plate 100. The loading assembly 200 is used to place the manifold 300. The loading assembly 200 is provided with a positioning assembly 400 for positioning the manifold 300 on the loading assembly 200; the separation assembly 500 is arranged on the loading assembly 200, and the separation assembly 500 can separate the manifold 300 from the loading assembly 200; the pressing assembly 600 is slidably arranged on the bottom plate 100, and the pressing assembly 600 is opposite to the loading assembly 200. The pressing assembly 600 is provided with a pre-punching knife 610 and a dilating knife 620 on the side facing the loading assembly 200, and the pre-punching knife 610 can The pre-punching knife 620 can pierce the surface of the manifold 300 into a pre-punched hole 310, and the expanding knife 620 can expand the two sides of the pre-punched hole 310. When punching the side of the manifold 300, the manifold 300 needs to be placed on the side of the loading component 200 facing the pressing component 600, so that the pre-punching knife 610 is aligned with the side of the manifold 300, and one end of the positioning component 400 is inserted into the manifold 300. At this time, the pressing component 600 is in the initial position. Afterwards, the pressing component 600 is driven to move toward the loading component 200. During this process, the pre-punching knife 610 will contact the side of the manifold 300 and punch the manifold 300 until the pre-punching knife 610 is on the surface of the manifold 300. When the pre-punched hole 310 is punched out on the surface, the pressing assembly 600 is driven to move in the direction away from the loading assembly 200 until the pressing assembly 600 is reset to the initial position. Thereafter, the loading assembly 200 moves laterally relative to the base plate 100, and when the manifold 300 is facing the expanding and punching knife 620, the loading assembly 200 stops moving and the pressing assembly 600 is driven to move toward the loading assembly 200 again. During this process, the expanding and punching knife 620 will be inserted into the pre-punched hole 310 on the surface of the manifold 300 and expand the two sides of the pre-punched hole 310 until the two sides of the expanding and punching knife 620 punch out dents on the inner walls of the manifold 300 on both sides of the pre-punched hole 310. The expanding and punching knife 620 is completed and the pressing assembly is driven. 600 moves in the direction away from the loading component 200 until the pressing component 600 is reset to the initial position again, driving the positioning component 400 to be pulled out of the positioning groove 320 of the manifold 300. Thereafter, the disengagement component 500 separates the manifold 300 from the loading component 200, so that the technician can smoothly take away the manifold 300. In this way, the vertical punching structure can complete the automated pre-punching 310 and expansion work of the manifold 300, so as to avoid the expanding and punching knife 620 directly punching and expanding the manifold 300, reducing the possibility of the manifold 300 being squeezed and deformed. Secondly, it can also avoid the center of the end of the expanding and punching knife 620 from damaging the inner wall of the manifold 300. In addition, it can also reduce manual operations.

[0043] In the present invention, the entire movable vertical thrust structure is installed on the base plate 100. Therefore, when in use, the movable vertical thrust structure can be used by simply placing the base plate 100 on a plane. In this way, the use environment of the movable vertical thrust structure can be effectively expanded, and at the same time, it is also convenient for people to carry the movable vertical thrust structure.

[0044] like Figure 1 — Figure 5 and Figure 7 As shown, further, a pointed tip 611 is provided at the center of the pre-punching knife 610 away from the pressing assembly 600, wherein the pre-punching knife 610 is provided with arc grooves 612 on both sides of the pointed tip 611, and the width of the pre-punching knife 610 is smaller than the inner diameter of the manifold 300, wherein the positioning groove 320 and the pre-punching hole 310 are respectively located on both sides of the central axis of the manifold 300, so that when the pre-punching knife 610 contacts the manifold 300, the pointed tip 611 will preferentially punch the side of the manifold 300, and then the arc groove 612 cuts the manifold 300. When the arc groove 612 is inserted into the manifold 300, the pre-punching hole 310 of the manifold 300 is completed; when the pre-punching knife 620 is away from the manifold 300, the pre-punching hole 310 of the manifold 300 is completed. A semicircular plate 621 is provided at one end of the pressing assembly 600. The diameter of the semicircular plate 621 is larger than the diameter of the inner wall of the collecting tube 300 and smaller than the diameter of the outer wall of the collecting tube 300. In this way, it can be ensured that the semicircular plate 621 can expand and press out dents on the parts of the inner wall of the collecting tube 300 located on both sides of the pre-punched hole 310. Furthermore, technicians can reasonably set the length of the expanding knife 620 according to technical requirements. In this way, in the process of the semicircular plate 621 pressing out dents on the collecting tube 300, it is always ensured that the center position of the edge of the semicircular plate 621 is always not in contact with the inner wall of the collecting tube 300, so as to avoid the semicircular plate 621 damaging the side of the inner wall of the collecting tube 300 close to the positioning groove 320.

[0045] The loading assembly 200 includes a loading plate 210, on which a closing plate 220 is provided, and a partition 230 is provided between the loading plate 210 and the closing plate 220. The positioning assembly 400 and the separation assembly 500 are both provided on the loading plate 210, and both the positioning assembly 400 and the separation assembly 500 can pass through the closing plate 220. The bottom plate 100 is provided with a second guide rail 110 for guiding the loading plate 210 to move horizontally relative to the bottom plate 100. The bottom of the loading plate 210 is provided with a second guide rail 110 for guiding the loading plate 210 to move horizontally relative to the bottom plate 100. The second guide rail 110 is slidably connected to the second slider 211, and a push cylinder 120 with a push rod 121 is set on the base plate 100. The push rod 121 is connected to one side of the loading plate 210, wherein the second guide rail 110 is arranged horizontally relative to the base plate 100. When the push cylinder 120 drives the push rod 121 to move, the push rod 121 will move the loading plate 210 along the track of the second guide rail 110, thereby realizing the horizontal movement of the loading assembly 200 and the collecting pipe 300 relative to the base plate 100.

[0046] A first stopper 130 and a second stopper 140 are provided on the bottom plate 100. The first stopper 130 and the second stopper 140 are respectively located at the two ends of the second guide rail 110. A fixing seat 150 is provided on the bottom plate 100, wherein the fixing seat 150 is located directly below the closing template 220. A drain hole 151 is provided on the fixing seat 150 and the bottom plate 100. The second stopper 140 is located at one end of the second guide rail 110 close to the push cylinder 120. When punching the pre-punched hole 310 on the surface of the manifold 300, it is necessary to press one side of the loading plate 210 against the first stopper 130 to align the manifold 300 with the pre-punched knife 610, so that the pre-punched knife 610 punches the pre-punched hole 310 on the side of the manifold 300. In this process, Because the drain hole 151 is located just below the manifold 300, when the pre-punching knife 610 punches the manifold 300, the waste on the manifold 300 will naturally fall into the drain hole 151 and be discharged to the bottom of the bottom plate 100 through the drain hole 151, making it convenient for people to clean up; and when the other side of the loading plate 210 is against the second stop block 140, the expanding and punching knife 620 is just aligned with the pre-punching hole 310 of the manifold 300, so that the expanding and punching knife 620 can expand the pre-punching hole 310; further, when the manifold 300 is positioned and installed in the manifold tank 221, there is a certain distance between the bottom end of the manifold 300 and the fixed seat 150 to avoid the fixed seat 150 interfering with the manifold 300 when the manifold 300 moves.

[0047] The pressing assembly 600 includes a pressing plate 650 and a movable plate 630 that can move relative to the pressing plate 650. The pre-punching knife 610 and the expanding knife 620 are both arranged on the pressing plate 650. When the movable plate 630 is pressed against the pressing plate 650, the pre-punching knife 610 and the expanding knife 620 pass through the movable plate 630. The movable plate 630 is provided with a knife groove 631 corresponding to the pre-punching knife 610 and the expanding knife 620 on the side away from the pressing plate 650. The pre-punching knife 610 can pass through the inner wall of one of the knife grooves 631, and the expanding knife 620 can pass through the inner wall of the other knife groove 631. A manifold 221 for mounting the manifold 300 is provided on the side away from the loading plate 210. A plurality of springs 640 are provided between the pressing plate 650 and the movable plate 630. When the pressing assembly 600 is not in use, a gap is created between the movable plate 630 and the pressing plate 650 due to the springs 640 between the movable plate 630 and the pressing plate 650. This allows the tip 611 of the pre-punching knife 610 and the semicircular plate 621 of the expanding knife 620 to be hidden in the movable plate 630. When the pre-punching knife 610 pre-punches the manifold 300 or the expanding knife 620 pre-punches the pre-punched hole 310, the semicircular plate 621 of the expanding knife 620 is hidden in the movable plate 630. When the forming is performed, it is necessary to ensure that one of the knife grooves 631 is aligned with the manifold 221. Then, the pressing plate 650 is driven to move toward the mold plate 220. During this process, the movable plate 630 will first contact the mold plate 220. At the same time, the knife groove 631 aligned with the manifold 221 will wrap the side of the manifold 300 with the manifold 221. After that, the pressing plate 650 continues to move toward the mold plate 220. The spring 640 is compressed, and the gap between the movable plate 630 and the pressing plate 650 will gradually decrease. At this time, the pre-punching knife 610 and the expanding punching knife 620 will be inserted into the corresponding In the knife groove 631, in this way, the pre-punching knife 610 will punch the side of the manifold 300 to form the pre-punched hole 310 or the expanding knife 620 will expand the two sides of the pre-punched hole 310. When the pressing plate 650 moves away from the closing template 220, the movable plate 630 is acted upon by the elastic force of the spring 640. The movable plate 630 will first stick to the closing template 220 to increase the gap between the movable plate 630 and the pressing plate 650. When the distance between the movable plate 630 and the pressing plate 650 reaches a certain distance, the movable plate 630 will press the pressing plate 650 and move it away from the closing template 220.

[0048] A positioning column 651 is provided on the pressing plate 650, and the positioning column 651 passes through the movable plate 630. The closing plate 220, the partition plate 230 and the loading plate 210 are all provided with a plurality of positioning holes 240 corresponding to the positioning column 651. Through the action of the positioning column 651, when the movable plate 630 moves relative to the pressing plate 650, the movable plate 630 can move in a direction along the trajectory of the positioning column 651. When the collecting pipe 300 is pre-punched 310 or expanded, the positioning column 651 will be inserted into the corresponding positioning hole 240, thereby achieving the effect of avoiding the positioning column 651.

[0049] A first guide rail 160 is provided on the base plate 100, and a first slider 653 is provided at the bottom of the pressing plate 650 which is slidably connected to the first guide rail 160. During operation, the pressing plate 650 slides along the track of the first guide rail 160 through the first slider 653, thereby realizing directional movement of the pressing plate 650. Since the extension line of the first guide rail 160 is perpendicular to the second guide rail 110, the movement direction of the pressing assembly 600 and the movement direction of the loading plate 210 are perpendicular to each other, so that the pressing assembly 600 and the closing plate 220 can be in stable contact, and the pre-punching knife 610 or the expanding punching knife 620 can punch the collecting pipe 300.

[0050] The pressing plate 650 is provided with a plurality of guide sleeves 652, each of which is equipped with an anti-detachment bolt 652a. The guide sleeve 652 can be inserted into the movable plate 630. The diameter of the guide sleeve 652 is larger than the diameter of the middle part of the anti-detachment bolt 652a, and the diameter of the anti-detachment bolt 652a at one end away from the guide sleeve 652 is larger than the diameter of the middle part of the anti-detachment bolt 652a. The movable plate 630 is provided with a first insertion hole (not marked in the figure), a second insertion hole (not marked in the figure) and a third insertion hole 632. The second insertion hole is located between the first insertion hole and the third insertion hole 632. The diameters of the first insertion hole and the third insertion hole 632 are both larger than the diameter of the second insertion hole. The first insertion hole is for the guide sleeve 652 to be inserted. The diameter of the guide sleeve 652 and the diameter of the anti-detachment bolt 652a at one end away from the guide sleeve 652 are both larger than the diameter of the second insertion hole. The fourth insertion hole for the anti-detachment bolt 652a to be inserted is provided on the closing template 220. When the movable plate 630 moves toward the pressing plate 650, the guide sleeve 652 is inserted into the first insertion hole, and when the movable plate 630 presses against the pressing plate 650, the guide sleeve 652 is fully inserted into the first insertion hole. At the same time, the end of the anti-detachment bolt 652a away from the guide sleeve 652 is inserted into the fourth insertion hole 222. When the movable plate 630 moves in the direction away from the pressing plate 650, the guide sleeve 652 moves out of the first insertion hole, and the end of the anti-detachment bolt 652a away from the guide sleeve 652 moves out of the fourth insertion hole 222 and transfers to the third insertion hole 632 until the end of the anti-detachment bolt 652a presses against the end of the third insertion hole 632 close to the second hole to prevent the movable plate 630 from detaching from the pressing plate 650. During this process, the end of the guide sleeve 652 away from the pressing plate 650 is always inserted into the first insertion hole, so that the guide sleeve 652 plays the role of guiding the directional movement of the movable plate 630.

[0051] like Figure 1 and Figure 4 — Figure 8 As shown, the positioning assembly 400 includes a positioning cylinder body 410 provided on the loading plate 210, and a positioning plate 420 is provided on the positioning cylinder body 410, and the positioning plate 420 can pass through the top of the closing plate 220. When the positioning assembly 400 is not in use, the end of the positioning plate 420 away from the positioning cylinder body 410 is located in the partition 230. When in use, the end of the positioning plate 420 away from the positioning cylinder body 410 is inserted into the collecting groove 221 of the closing plate 220, and inserted into the positioning groove 320 of the collecting pipe 300, so as to realize the positioning and installation of the collecting pipe 300 in the collecting groove 221. Furthermore, the number of the positioning plates 420 can be multiple, which can further improve the stability of the collecting pipe 300 in the collecting groove 221; further, the height of the pre-punching knife and the expansion knife is the same, and the height of the positioning plate is different from that of the pre-punching knife, so as to avoid the positioning plate interfering with the pre-punching knife or the expansion knife.

[0052] The disengagement assembly 500 includes a disengagement cylinder 510 disposed on the top of the loading plate 210, a disengagement plate 511 is provided on the disengagement cylinder 510, and the disengagement plate 511 can pass through the loading plate 210. The top edge of the closing plate 220 is provided with an anti-slip plate 520, and the middle of the anti-slip plate 520 is provided with an anti-slip groove 521. The disengagement plate 511 can push the top of the manifold 300 into the anti-slip groove 521. When the stamping of the manifold 300 is completed and the positioning plate 420 is removed from the manifold 300, the manifold 300 is pushed out of the opening. After moving out, it is necessary to operate the disengagement cylinder 510 to push out the disengagement plate 511, so that the disengagement plate 511 pushes the top of the collecting pipe 300 toward the anti-detachment plate 520 until the top of the collecting pipe 300 is embedded in the anti-detachment groove 521. During this process, the collecting pipe 300 is separated from the closing template 220, and the bottom of the collecting pipe 300 falls onto the fixing seat 150. In this way, people can hold the top of the collecting pipe 300 and smoothly remove the collecting pipe 300 from the anti-detachment groove 521.

[0053] At least two fixed plates 170 are provided on the base plate 100, and a side guide rail 171 is provided between the two fixed plates 170. One side of the loading plate 210 is slidably connected to the side guide rail 171. When the bottom of the loading plate 210 moves along the track of the second guide rail 110, the side of the loading plate 210 will move along the track of the side guide rail 171, thereby further ensuring the stability of the loading plate 210 during movement and preventing the loading plate 210 from overturning toward the side of the closing plate 220.

[0054] A seat plate 180 is provided on the base plate 100, and at least two guide rods 181 are provided on the seat plate 180, and the guide rods 181 pass through the pressing plate 650. The base plate 100 is provided with a seat body 190 with the same number as the guide rods 181, wherein the seat body 190 is connected to the corresponding guide rods 181, and the seat plate 180 is provided with a pressing cylinder body 182 for pushing the pressing plate 650 to move relative to the base plate 100, and the guide rod 181 is parallel to the first guide rail 160. When working, the pressing cylinder body 182 pushes the pressing plate 650 to move. During this process, the bottom of the pressing plate 650 moves in a directional manner along the trajectory of the first guide rail 160, and the two ends of the pressing plate 650 move in a directional manner along the trajectory of the guide rods 181. In this way, the stability of the pressing plate 650 during the movement can be further improved.

[0055] Example 2

[0056] like Figure 1 — Figure 8 As shown, this embodiment is a punching method for the above-mentioned movable vertical punch structure, comprising the following steps:

[0057] Ensure that the pressing plate 650 is in the initial position, and ensure that one side of the loading plate 210 is against the first stopper 130, so that the collecting groove 221 is aligned with the knife groove 631 where the pre-punching knife 610 is located. After that, the technician places the collecting pipe 300 in the collecting groove 221 of the closing plate 220, and the collecting pipe 300 is just above the drain hole 151, and ensures that a certain distance is reserved between the bottom of the collecting pipe 300 and the fixing seat 150. The positioning plate 420 is aligned with the positioning groove 320 of the collecting pipe 300, so that the pre-punching knife 610 is aligned with the side of the collecting pipe 300. Thereafter, the positioning cylinder 410 is controlled to make the positioning plate 420 pass through the positioning groove 320 of the collecting pipe 300 and insert into the interior of the collecting pipe 300, so that the collecting pipe 300 is positioned and installed in the collecting groove 221;

[0058] The pressing cylinder 182 is controlled to drive the pressing plate 650 to move toward the loading plate 210. During this process, the movable plate 630 will preferentially contact the plate 220. At the same time, the knife groove 631 aligned with the manifold 221 will wrap the side of the manifold 300 with the manifold 221. After that, the pressing plate 650 continues to move toward the plate 220. The spring 640 is compressed, and the gap between the movable plate 630 and the pressing plate 650 gradually decreases. At this time, the pre-punching knife 610 and the expanding knife 620 will be inserted into the corresponding knife groove 631 at the same time. In this way, the pre-punching knife 610 will punch the side of the manifold 300 to form the pre-punched hole 310.

[0059] After the pre-punching knife 610 punches the pre-punched hole 310 on the surface of the manifold 300, the pressing cylinder 182 drives the pressing plate 650 to move away from the loading plate 210. The movable plate 630 is acted upon by the elastic force of the spring 640. The movable plate 630 first contacts the closing plate 220 to increase the gap between the movable plate 630 and the pressing plate 650. When the movable plate 630 and the pressing plate 650 reach a certain distance, the movable plate 630 moves along with the pressing plate 650 away from the closing plate 220 until the entire pressing assembly 600 returns to its initial position.

[0060] The push cylinder 120 drives the loading plate 210 to move toward the second stopper 140. When the other side of the loading plate 210 abuts against the second stopper 140, the push cylinder 120 stops working. At this time, the expanding and punching blade 620 is aligned with the pre-punched hole 310 of the manifold 300.

[0061] The pressing cylinder 182 drives the pressing plate 650 to move toward the loading plate 210. During this process, the gap between the movable plate 630 and the pressing plate 650 is reduced, and the expanding and punching blade 620 is inserted into the pre-punched hole 310 on the surface of the manifold 300 and expands the sides of the pre-punched hole 310 until the expanding and punching blade 620 has punched out indentations on the inner wall of the manifold 300 on both sides of the pre-punched hole 310. The expanding and punching work of the expanding and punching blade 620 is completed.

[0062] After the expansion is completed, the pressing cylinder 182 is controlled to drive the pressing plate 650 to return to the initial position;

[0063] The positioning cylinder 410 drives the positioning plate 420 to be pulled out from the manifold 300, and the end of the positioning plate 420 is hidden in the partition 230. After that, the disengagement cylinder 510 needs to be controlled to push out the disengagement plate 511, so that the disengagement plate 511 pushes the top of the manifold 300 toward the anti-detachment plate 520 until the top of the manifold 300 is embedded in the anti-detachment groove 521. In this process, the manifold 300 is separated from the closing template 220, and the bottom of the manifold 300 falls onto the fixing seat 150. In this way, people can hold the top of the manifold 300 and smoothly remove the manifold 300 from the anti-detachment groove 521.

[0064] Through the punching method of the above-mentioned movable vertical punching structure, the pre-punching 310 and the expansion hole automation work of the collecting pipe 300 can be completed in sequence, and the two sides of the expanding and punching knife 620 can punch out dents on the inner wall of the collecting pipe 300 on both sides of the pre-punching hole 310. Secondly, it can also avoid the expanding and punching knife 620 directly acting on the collecting pipe 300, resulting in the possibility of the collecting pipe 300 being squeezed and deformed by the expanding and punching knife 620.

[0065] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship, movement, etc. between the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, descriptions such as "first", "second", "one", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" can explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0066] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0067] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
