Description

Technical Field

[0001] The present invention belongs to the technical field of manifold punching equipment, and relates to a movable vertical punching structure for a manifold and a punching method thereof. Background Art

[0002] Currently, manifold punching dies are usually fixed on large punching presses, and the operation process is as follows: Workers manually place the manifold into the punching groove station of the die. After starting the punching press to complete the downward punching groove, the semi-finished product is moved to the bulging station for secondary stamping, and finally the finished product is taken out to complete the processing. However, this process has two prominent problems: First, when manually placing and removing the manifold, the hand needs to be inserted into the die area, posing a safety hazard of mechanical injury; Second, manual operation is prone to cause product positioning deviation, which in turn leads to quality problems such as inaccurate punching positions.

Detailed implementation manners

[0024] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0025] Embodiment 1 As Figure 1 — Figure 8 shown, a movable vertical punching structure for a manifold pipe of the present invention includes a bottom plate 100, a loading assembly 200, a positioning assembly 400, a disengaging assembly 500, a pressing assembly 600, a pre-punching knife 610, and an expanding punching knife 620.

[0026] In the present invention, a positioning groove 320 corresponding to the positioning assembly 400 is provided on the side surface of the manifold pipe 300; the movable vertical punching structure of the present invention further includes a control system (not marked in the figure) for controlling the positioning assembly 400, the disengaging assembly 500, the pressing assembly 600, and the pushing cylinder block.

[0027] The loading assembly 200 is disposed on the bottom plate 100. The loading assembly 200 can move laterally relative to the bottom plate 100. The loading assembly 200 is used to place the manifold 300. A positioning assembly 400 for positioning and arranging the manifold 300 on the loading assembly 200 is provided on the loading assembly 200. A separating assembly 500 is disposed on the loading assembly 200. The separating assembly 500 can separate the manifold 300 from the loading assembly 200. A pressing assembly 600 is slidably disposed on the bottom plate 100. The pressing assembly 600 faces the loading assembly 200. On the surface of the pressing assembly 600 facing the loading assembly 200, a pre-punching knife 610 and an expanding punching knife 620 are provided. The pre-punching knife 610 can puncture a pre-punching hole 310 on the surface of the manifold 300. The expanding punching knife 620 can expand the two sides of the pre-punching hole 310. When punching holes on the side surface of the manifold 300, first, the manifold 300 needs to be placed on the surface of the loading assembly 200 facing the pressing assembly 600, align the pre-punching knife 610 with the side surface of the manifold 300, and insert one end of the positioning assembly 400 into the manifold 300. At this time, the pressing assembly 600 is in the initial position. Then, drive the pressing assembly 600 to move towards the loading assembly 200. During this process, the pre-punching knife 610 will contact the side surface of the manifold 300 and punch holes in the manifold 300 until the pre-punching knife 610 punches a pre-punching hole 310 on the surface of the manifold 300. Then, drive the pressing assembly 600 to move away from the loading assembly 200 until the pressing assembly 600 resets to the initial position. After that, the loading assembly 200 moves laterally relative to the bottom plate 100. And when the manifold 300 is facing the expanding punching knife 620, the loading assembly 200 stops moving. Drive the pressing assembly 600 to move towards the loading assembly 200 again. During this process, the expanding punching knife 620 will insert into the pre-punching hole 310 on the surface of the manifold 300 and expand the two sides of the pre-punching hole 310 until concave marks are punched on the inner walls of the manifold 300 on both sides of the pre-punching hole 310 by the two sides of the expanding punching knife 620, and the expanding work of the expanding punching knife 620 ends. Drive the pressing assembly 600 to move away from the loading assembly 200 until the pressing assembly 600 resets to the initial position again. Drive the positioning assembly 400 to be pulled out from the positioning groove 320 of the manifold 300. After that, the separating assembly 500 separates the manifold 300 from the loading assembly 200. In this way, the technician can smoothly take away the manifold 300. In this way, the automatic pre-punching 310 and hole expanding work of the vertical punching structure on the manifold 300 can be completed, so as to avoid directly punching holes and expanding holes on the manifold 300 by the expanding punching knife 620, reduce the possibility of the manifold 300 being extruded and deformed. Secondly, it can also avoid the center of the end of the expanding punching knife 620 from damaging the inner wall of the manifold 300. In addition, it can also reduce manual operation.

[0028] In the present invention, the entire movable vertical punching structure is installed on the bottom plate 100. Therefore, during use, simply placing the bottom plate 100 on a flat surface allows the use of this movable vertical punching structure. In this way, the usage environment of this movable vertical punching structure can be effectively expanded, and at the same time, it is also convenient for people to carry this movable vertical punching structure.

[0029] As Figure 1 — Figure 5 and Figure 7 shown, further, a pointed head 611 is provided at the center of the end of the pre-punching knife 610 away from the pressing component 600. Among them, arc grooves 612 are provided on both sides of the pre-punching knife 610 where the pointed head 611 is located. The width of the pre-punching knife 610 is smaller than the inner diameter of the manifold 300. Among them, the positioning groove 320 and the pre-punching hole 310 are respectively located on both sides of the central axis of the manifold 300. In this way, when the pre-punching knife 610 contacts the manifold 300, the pointed head 611 will first punch the side of the manifold 300. After that, the arc grooves 612 cut the manifold 300. When the arc grooves 612 are inserted into the manifold 300, the pre-punching hole 310 work of the manifold 300 is completed; a semi-circular plate 621 is provided at the end of the expanding punching knife 620 away from the pressing component 600. The diameter of the semi-circular plate 621 is larger than the inner diameter of the inner wall of the manifold 300 and smaller than the outer diameter of the outer wall of the manifold 300. In this way, it can be ensured that the semi-circular plate 621 can expand the parts of the inner wall of the manifold 300 on both sides of the pre-punching hole 310 and press out indentations. Further, technicians can reasonably set the length of the expanding punching knife 620 according to technical requirements. In this way, during the process of the semi-circular plate 621 pressing out indentations on the manifold 300, it is always ensured that the central position at the edge of the semi-circular plate 621 does not contact the inner wall of the manifold 300, so as to avoid the semi-circular plate 621 damaging the side of the inner wall of the manifold 300 close to the positioning groove 320.

[0030] The loading component 200 includes a loading plate 210. A template closing plate 220 is provided on the loading plate 210. A partition plate 230 is provided between the loading plate 210 and the template closing plate 220. The positioning component 400 and the disengaging component 500 are both provided on the loading plate 210. The positioning component 400 and the disengaging component 500 can both pass through the template closing plate 220. A second guide rail 110 for guiding the lateral movement of the loading plate 210 relative to the bottom plate 100 is provided on the bottom plate 100. A second slider 211 slidably connected to the second guide rail 110 is provided at the bottom of the loading plate 210. A pushing cylinder body 120 with a pushing rod 121 is provided on the bottom plate 100. The pushing rod 121 is connected to one side of the loading plate 210. Among them, the second guide rail 110 is horizontally arranged relative to the bottom plate 100. When the pushing cylinder body 120 drives the pushing rod 121 to move, the pushing rod 121 will drive the loading plate 210 to move along the track of the second guide rail 110, so as to realize the lateral movement of the loading component 200 and the manifold 300 relative to the bottom plate 100.

[0031] A first stop block 130 and a second stop block 140 are provided on the bottom plate 100. The first stop block 130 and the second stop block 140 are respectively located at two ends of the second guide rail 110. A fixing seat 150 is provided on the bottom plate 100. Among them, the fixing seat 150 is located directly below the mold clamping plate 220. Drainage holes 151 are provided on both the fixing seat 150 and the bottom plate 100. The second stop block 140 is located at one end of the second guide rail 110 close to the pushing cylinder body 120. When punching a pre-punching hole 310 on the surface of the manifold pipe 300, one side of the loading plate 210 needs to be abutted against the first stop block 130 so that the manifold pipe 300 is aligned with the pre-punching knife 610, so that the pre-punching knife 610 punches a pre-punching hole 310 on the side surface of the manifold pipe 300. During this process, since the drainage hole 151 is exactly located directly below the manifold pipe 300, when the pre-punching knife 610 punches the manifold pipe 300, the waste chips on the manifold pipe 300 will naturally fall into the drainage hole 151 and be discharged below the bottom plate 100 through the drainage hole 151 for people to clean up easily; and when the other side of the loading plate 210 abuts against the second stop block 140, the expanding punch 620 is exactly aligned with the pre-punching hole 310 of the manifold pipe 300, so that the expanding punch 620 can expand the pre-punching hole 310; further, when the manifold pipe 300 is positioned and installed in the manifold groove 221, there is a certain distance between the bottom end of the manifold pipe 300 and the fixing seat 150 to prevent the fixing seat 150 from interfering with the manifold pipe 300 when the manifold pipe 300 moves.

[0032] The pressing component 600 includes a pressing plate 650 and a movable plate 630 capable of moving relative to the pressing plate 650. The pre-punching knife 610 and the expanding punching knife 620 are both arranged on the pressing plate 650. When the movable plate 630 abuts against the pressing plate 650, the pre-punching knife 610 and the expanding punching knife 620 penetrate through the movable plate 630. Knife grooves 631 corresponding to the pre-punching knife 610 and the expanding punching knife 620 are provided on one side of the movable plate 630 away from the pressing plate 650. The pre-punching knife 610 can penetrate through the inner wall of one of the knife grooves 631, and the expanding punching knife 620 can penetrate through the inner wall of the other knife groove 631. A manifold groove 221 for installing the manifold pipe 300 is provided on one side of the template 220 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 component 600 is not in use, due to the spring 640 between the movable plate 630 and the pressing plate 650, a gap is generated between the movable plate 630 and the pressing plate 650, so that the tip 611 of the pre-punching knife 610 and the semi-circular plate 621 of the expanding punching knife 620 are hidden inside the movable plate 630. When the pre-punching knife 610 punches a pre-punching hole 310 in the manifold pipe 300 or the expanding punching knife 620 expands the pre-punching hole 310, it is necessary to first ensure that one of the knife grooves 631 is aligned with the manifold groove 221. Then, the pressing plate 650 is driven to move towards the template 220. During this process, the movable plate 630 will first contact the template 220. At the same time, the knife groove 631 aligned with the manifold groove 221 and the manifold groove 221 will wrap the side of the manifold pipe 300. After that, the pressing plate 650 continues to move towards the template 220, and the spring 640 is compressed under force, 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 punching knife 620 will be inserted into the corresponding knife grooves 631 at the same time. In this way, the pre-punching knife 610 will punch the side of the manifold pipe 300 to form a pre-punching hole 310 or the expanding punching knife 620 will expand the two sides of the pre-punching hole 310. When the pressing plate 650 moves away from the template 220, the movable plate 630 is affected by the elastic force of the spring 640, and the movable plate 630 will first stick to the template 220 to increase the gap between the movable plate 630 and the pressing plate 650. And 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 to move away from the template 220.

[0033] The pressing plate 650 is provided with positioning posts 651. The positioning posts 651 pass through the movable plate 630. A plurality of positioning holes 240 corresponding to the positioning posts 651 are provided on the template 220, the partition plate 230 and the loading plate 210. Through the action of the positioning posts 651, when the movable plate 630 moves relative to the pressing plate 650, the movable plate 630 can move directionally along the trajectory of the positioning posts 651. When pre-punching 310 or bulging the manifold 300, the positioning posts 651 will be inserted into the corresponding positioning holes 240, so as to achieve the effect of avoiding the positioning posts 651.

[0034] The bottom plate 100 is provided with a first guide rail 160. The bottom of the pressing plate 650 is provided with a first slider 653 slidably connected to the first guide rail 160. During operation, the pressing plate 650 slides along the trajectory of the first guide rail 160 through the first slider 653, so as to realize the 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 is perpendicular to the movement direction of the loading plate 210, so that the pressing assembly 600 can stably contact the template 220, and the pre-punching knife 610 or the expanding punching knife 620 can punch the manifold 300.

[0035] A plurality of guide sleeves 652 are provided on the pressing plate 650, and an anti - detachment bolt 652a is installed on each of the guide sleeves 652. 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. The diameter of the end of the anti - detachment bolt 652a away from the guide sleeve 652 is larger than the diameter of the middle part of the anti - detachment bolt 652a. A first jack (not marked in the figure), a second jack (not marked in the figure) and a third jack 632 are provided in the movable plate 630. The second jack is located between the first jack and the third jack 632. The diameters of the first jack and the third jack 632 are both larger than the diameter of the second jack. The first jack is for the guide sleeve 652 to be inserted. The diameters of the guide sleeve 652 and the end of the anti - detachment bolt 652a away from the guide sleeve 652 are both larger than the diameter of the second jack. A fourth jack 222 for the anti - detachment bolt 652a to be inserted is provided on the die - closing plate 220. When the movable plate 630 moves towards the pressing plate 650, the guide sleeve 652 is inserted into the first jack. And when the movable plate 630 abuts against the pressing plate 650, the guide sleeve 652 is completely inserted into the first jack. At the same time, the end of the anti - detachment bolt 652a away from the guide sleeve 652 is inserted into the fourth jack 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 jack, and the end of the anti - detachment bolt 652a away from the guide sleeve 652 moves out of the fourth jack 222 and transfers to the third jack 632 until the end of the anti - detachment bolt 652a abuts against one end of the third jack 632 close to the second jack to prevent the movable plate 630 from detaching from the pressing plate 650. And during this process, the end of the guide sleeve 652 away from the pressing plate 650 is always inserted into the first jack so that the guide sleeve 652 plays a role in guiding the directional movement of the movable plate 630.

[0036] As Figure 1 and Figure 4 — Figure 8 As shown, the positioning assembly 400 includes a positioning cylinder block 410 provided on the loading plate 210. A positioning plate 420 is provided on the positioning cylinder block 410. The positioning plate 420 can pass through the top of the die - closing plate 220. When the positioning assembly 400 is not in use, the end of the positioning plate 420 away from the positioning cylinder block 410 is located inside the partition plate 230. When in use, the end of the positioning plate 420 away from the positioning cylinder block 410 is inserted into the flow - collecting groove 221 of the die - closing plate 220 and inserted into the positioning groove 320 of the flow - collecting pipe 300 to realize the positioning and installation of the flow - collecting pipe 300 in the flow - collecting groove 221. Further, the number of the positioning plates 420 can be multiple, which can further improve the stability of the flow - collecting pipe 300 in the flow - collecting groove 221. Further, the heights of the pre - punching knife and the expanding - punching knife are the same, and the height of the positioning plate is different from that of the pre - punching knife to avoid the positioning plate interfering with the pre - punching knife or the expanding - punching knife.

[0037] The separation component 500 includes a separation cylinder body 510 provided on the top of the loading plate 210. A separation plate 511 is provided on the separation cylinder body 510. The separation plate 511 can pass through the loading plate 210. An anti-separation plate 520 is provided on the top edge of the combined template 220. An anti-separation groove 521 is provided in the middle of the anti-separation plate 520. The separation plate 511 can push the top end of the manifold 300 into the anti-separation groove 521. When the stamping of the manifold 300 is completed and the positioning plate 420 is removed from the manifold 300, it is necessary to control the separation cylinder body 510 to push out the separation plate 511, so that the separation plate 511 pushes the top of the manifold 300 towards the anti-separation plate 520 until the top of the manifold 300 is embedded in the anti-separation groove 521. During this process, the manifold 300 is separated from the combined template 220, and the bottom of the manifold 300 falls onto the fixed seat 150. In this way, people can hold the top of the manifold 300 and thus smoothly take out the manifold 300 from the anti-separation groove 521.

[0038] At least two fixing plates 170 are provided on the bottom plate 100. A side guide rail 171 is provided between the two fixing 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 the movement and also preventing the loading plate 210 from tipping to one side of the combined template 220.

[0039] A seat plate 180 is provided on the bottom plate 100. At least two guide rods 181 are provided on the seat plate 180. The guide rods 181 pass through the pressing plate 650. Seat bodies 190 with the same number as the guide rods 181 are provided on the bottom plate 100. Among them, the seat bodies 190 are connected to the corresponding guide rods 181. A pressing cylinder body 182 for pushing the pressing plate 650 to move relative to the bottom plate 100 is provided on the seat plate 180. The guide rods 181 are parallel to the first guide rail 160. During operation, the pressing cylinder body 182 pushes the pressing plate 650 to move. During this process, the bottom of the pressing plate 650 moves along the track of the first guide rail 160 in a fixed direction, and both ends of the pressing plate 650 move along the track of the guide rods 181 in a fixed direction. In this way, the stability of the pressing plate 650 during the movement can be further improved.

[0040] Embodiment 2 As Figure 1 — Figure 8 shown, this embodiment is a stamping method for the above-mentioned movable vertical stamping structure, including the following steps: Ensure that the pressing plate 650 is in the initial position, and ensure that one side of the loading plate 210 abuts against the first stopper 130, so that the flow collecting groove 221 is aligned with the tool groove 631 where the pre-punching tool 610 is located. After that, the technician places the manifold 300 into the flow collecting groove 221 of the mold clamping plate 220. The manifold 300 is exactly above the drain hole 151, and a certain distance is reserved between the bottom of the manifold 300 and the fixed seat 150. The positioning plate 420 is aligned with the positioning groove 320 of the manifold 300, so that the pre-punching tool 610 is aligned with the side surface of the manifold 300. After that, control the positioning cylinder block 410 to insert the positioning plate 420 into the interior of the manifold 300 through the positioning groove 320 of the manifold 300, realizing the positioning and installation of the manifold 300 in the flow collecting groove 221; Control the pressing cylinder block 182 to drive the pressing plate 650 to move towards the loading plate 210. During this process, the movable plate 630 will first contact the mold clamping plate 220. At the same time, the tool groove 631 aligned with the flow collecting groove 221 will wrap the side surface of the manifold 300 with the flow collecting groove 221. After that, the pressing plate 650 continues to move towards the mold clamping plate 220, and the spring 640 is compressed. The gap between the movable plate 630 and the pressing plate 650 will gradually decrease. At this time, the pre-punching tool 610 and the expanding punching tool 620 will simultaneously insert into the corresponding tool groove 631. In this way, the pre-punching tool 610 will punch the side surface of the manifold 300 to form a pre-punching hole 310; After the pre-punching tool 610 punches the pre-punching hole 310 on the surface of the manifold 300, control the pressing cylinder block 182 to drive the pressing plate 650 to move away from the loading plate 210. The movable plate 630 is affected by the elastic force of the spring 640. The movable plate 630 will first stick to the mold clamping plate 220, so that the gap between the movable plate 630 and the pressing plate 650 increases. And when the distance between the movable plate 630 and the pressing plate 650 reaches a certain distance, the movable plate 630 will move away from the mold clamping plate 220 along with the pressing plate 650 until the entire pressing assembly 600 resets to the initial position; The pushing cylinder block 120 drives the loading plate 210 to move towards the second stopper 140. When the other side of the loading plate 210 abuts against the second stopper 140, the pushing cylinder block 120 stops working. At this time, the expanding punching tool 620 is exactly aligned with the pre-punching hole 310 of the manifold 300; Control the pressing cylinder block 182 to drive the pressing plate 650 to move towards the loading plate 210. During this process, the gap between the movable plate 630 and the pressing plate 650 will decrease. The expanding punching tool 620 will insert into the pre-punching hole 310 on the surface of the manifold 300 and expand the two sides of the pre-punching hole 310 until concave marks are punched on the inner walls of the two sides of the manifold 300 where the pre-punching hole 310 is located by both sides of the expanding punching tool 620, and the expanding work of the expanding punching tool 620 ends; After the expanding is completed, control the pressing cylinder block 182 to drive the pressing plate 650 to reset to the initial position; The positioning cylinder block 410 drives the positioning plate 420 to be pulled out of the manifold 300, and the end of the positioning plate 420 is hidden inside the partition plate 230. After that, it is necessary to control the disengaging cylinder block 510 to push out the disengaging plate 511, so that the disengaging plate 511 pushes the top of the manifold 300 towards the anti-disengagement plate 520 until the top of the manifold 300 is embedded in the anti-disengagement groove 521. During this process, the manifold 300 is separated from the mold clamping plate 220, and the bottom of the manifold 300 drops onto the fixing seat 150. In this way, people can hold the top of the manifold 300 and thus smoothly take out the manifold 300 from the anti-disengagement groove 521.

[0041] Through the stamping method of the above-mentioned movable vertical punching structure, the pre-punching 310 of the manifold 300 and the hole expanding can be sequentially completed automatically, and indentations are punched on the inner walls of both sides of the manifold 300 where the pre-punching 310 is located on both sides by both sides of the expanding punch 620. Secondly, it can also avoid the possibility that the expanding punch 620 directly acts on the manifold 300, resulting in the extrusion deformation of the manifold 300 by the expanding punch 620.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly. In addition, in the present invention, descriptions such as "first", "second", "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
