Description

Technical Field

[0001] The utility model belongs to the technical field of metal exhaust pipe production equipment, in particular to a metal exhaust pipe finished product assembly device. Background Art

[0002] Gas water heaters use liquefied petroleum gas or natural gas as fuel. The heat generated by combustion is transferred to the water through a heat exchanger to heat it up. The gases generated during combustion need to be discharged to the outside world. Therefore, each combustion water heater will have an exhaust pipe, which usually has a straight section and a curved section. Usually, the exhaust pipe is produced in sections. Because if an integrated molding method is adopted, in order to accommodate the long metal pipe while keeping the steps unchanged, each placement position needs to be made very long, and the processing equipment needs to be made very large. Therefore, basically, segmented production is adopted, that is, the main pipe and the short pipe are produced separately. However, the current production process still requires a lot of manual assistance, and there is no complete automated assembly line production.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figure 1-5 ;

[0030] The assembly device described in the present invention is intended to perform the final assembly and molding of the combination of the main pipe and the short pipe. The device is part of an automated production line, so the material transfer process can be carried out by means of conveyor belts, mechanical clamping arms, etc. These are commonly used technical means, and specific reference can be made to the existing technology. In addition, the technical solution of the device can also be used as a separate device through modification, which will not be described in detail here. Prior to this, the short pipe has been corrugated, and the main pipe has been expanded, punched, and the end caps installed. The structure of the assembly device is described below.

[0031] Specifically, it includes a press-fit connection component 51, and an acquisition component 1 52 and an acquisition component 2 53 are respectively provided on both sides of the press-fit connection component 51, and the acquisition component 2 53 is connected to the pushing component 2 54; in this embodiment, there are many ways to acquire the main pipe and the short pipe, for example, during the transportation process, the main pipe and the short pipe are suspended respectively by mechanical clamps, and the acquisition component 1 52 and the acquisition component 2 53 are provided with structures similar to fixed claws to fix one end of the main pipe and the short pipe respectively; in the initial state, the acquisition component 1 52 and the acquisition component 2 53 are respectively at positions away from the press-fit connection component 51, and are in a horizontal state, reserving space for placing the main pipe and the short pipe, after the acquisition component 1 52 and the acquisition component 2 53 respectively obtain the main pipe and the short pipe, the acquisition component 1 52 pushes the main pipe to move so that one end of the main pipe is placed in the press-fit connection component 51, and at the same time, the acquisition component 2 53 pushes the short pipe to move so that one end of the short pipe is placed in the press-fit connection component In the connecting assembly 51, one end of the short tube is inserted into one end of the main tube. It should be noted that the inner diameters of the main tube and the short tube are generally the same. It can be understood as dividing a metal tube into two. However, the end of the main tube has been expanded in the previous step so that the inner diameter of the end of the main tube is slightly larger than the outer diameter of the short tube. After one end of the short tube is inserted into one end of the main tube, the outer wall of the short tube is close to the inner wall of the main tube. Then the press-fit connection assembly 51 is closed to clamp the connecting end of the main tube and the short tube. The inner diameter of the clamping position formed by the press-fit connection assembly 51 is slightly smaller than the outer diameter of the end of the main tube, so that the connecting end of the main tube and the short tube is slightly reduced. At the same time, the indentation flange 515 forms an indentation at the connecting end to fix the main tube and the short tube. It should be noted that the indentation flange 515 is in the shape of a ring and is adapted to the outer circumferential shape of the main tube. When the press-fit connection assembly 51 is closed, the indentation flange 515 can evenly apply pressure to the surface of the main tube to avoid deformation.

[0032] At this time, the press-fit connection component 51 maintains a press-fit fixed state, so that one end of the short tube is fixed, and the other end is fixed by the acquisition component 2 53. The connection method of the acquisition component 2 53 is that one end is rotatably connected to the external fixed component, and the other end is a free end. The fixed component is not limited. For the sake of compact structure, it is preferably rotatably connected to the press-fit connection component 51. Then the pushing component 2 54 pushes the acquisition component 2 53 to rotate a certain angle, that is, drives the other end of the short tube to rotate a certain angle. At this time, the corrugated part on the short tube will make corresponding changes to achieve bending forming.

[0033] Finally, obtain component 1, obtain component 2 53, and press-fit connection component 51 to loosen and reset the formed metal exhaust pipe, and take out the metal exhaust pipe through the blanking device to complete the entire forming process.

[0034] The utility model can realize the two steps of fastening the main pipe and the short pipe and bending the short pipe through the mutual cooperation of various components, and can form them in one step without separate operations. At the same time, it provides a final forming solution for the automated production line, laying a solid foundation for fully automatic production.

[0035] One embodiment of the press-fit connection assembly 51 of the present invention specifically includes a fixed platform 511, two cooperating forming blocks 512 are slidably connected to the fixed platform 511, and a driver thirteen for pushing the two forming blocks 512 to move. The two forming blocks 512 are combined to form a fixed position 1 514. By sliding and cooperating with the driver thirteen, the two forming blocks 512 can achieve an opening and closing action. The two forming blocks 512 have a semicircular groove, which is located in the semicircular groove to enclose the fixed position 1 514, and the indentation flange 515 is also divided into two parts, which are respectively arranged on the inner wall of the semicircular groove.

[0036] Furthermore, two sliding pairs 5134 are provided on the fixed frame, and the two sliding pairs 5134 are slidably connected to the plate 5135. The plate 5135 is arranged at the bottom of the forming block 512, which can better limit the moving direction of the forming block 512. Preferably, the connecting end of the forming block 512 is provided with a concave and convex position, which can enable the two forming blocks 512 to be aligned and closed.

[0037] Due to the limited space, the driver thirteen in this embodiment adopts a rotary driving method to drive the two forming blocks 512 to realize the opening and closing action, specifically including the output end of the rotating cylinder two 5131 is connected to the transmission block three 5132, and the two ends of the transmission block three 5132 are respectively rotatably connected to the transmission block four 5133, and the two transmission blocks four 5133 are respectively rotatably connected to the two forming blocks 512. The rotating cylinder two 5131 drives the transmission block three 5132 to rotate and change the position of the transmission block four 5133, so that the transmission block pulls or pushes the forming block 512, that is, the opening and closing action is realized. Of course, based on the above embodiment, the transmission block four 5133 can be rotatably connected to the plate 5135.

[0038] In addition, in order to strengthen the tightness of the two forming blocks 512, it is necessary to apply pressure to them from the outside. In this embodiment, cylinders 10 5161 are provided longitudinally on both sides of the two forming blocks 512, and the output end of the cylinder 10 5161 is installed with a movable block 1 5162, and the end of the movable block 1 5162 is provided with a roller 5163. The movable block 1 5162 in this embodiment is placed horizontally. In the initial state, the movable block 1 5162 is located above the forming block 512. If the cylinder 10 5161 drives the movable block 1 5162 to move downward at this time, the lower end surface of the movable block 1 5162 will conflict with the upper end surface of the forming block 512, and the purpose of applying external force to it cannot be achieved. Therefore, after the two forming blocks 512 are closed, space is left for the movable block 1 5162 to fall. At this time, the cylinder 10 5161 drives it to fall, and at the same time, the roller 5 5163 conflicts with the side of the forming block 512 to apply external force to it to keep it close to each other, so as to avoid loosening.

[0039] One embodiment of the second acquisition component 53 of the present invention specifically includes a fourth bracket 531. Preferably, one end of the fourth bracket 531 is rotatably connected to the fixed platform 511. A driver 14 532 is installed on the fourth bracket 531. In this embodiment, the driver 14 532 is a combination of a cylinder and a guide rail. A fixed block 533 is installed on the movable end of the driver 14. The fixed block 533 is rotatably connected to the fixed cylinder 534. Preferably, the fixed block 533 is slidably connected to the side of the fourth bracket 531. A position is provided in the fixed cylinder 534 to adapt to the end of the short tube so that it can enter. A limiter 535 is provided on the outside of the fixed cylinder 534. When in the loading state, the fixed cylinder 534 needs to be in a horizontal position to be aligned with the short tube. At this time, the limiter 535 conflicts with both sides of the fourth bracket 531 to limit its position.

[0040] In this embodiment, there is no position for placing the short tube, so when loading, the short tube is suspended in the bracket four 531 by a mechanical clamp, and then the driver fourteen 532 pushes the fixed cylinder 534 to move in the direction of the short tube, and finally the end of the short tube is fixed by the fixed cylinder 534; when a bending angle is required, the fixed cylinder 534 will rotate a certain angle relative to the fixed block 533, and adjust adaptively, and at the same time the limit member 535 is disengaged from the bracket four 531.

[0041] The pushing component 2 54 used in the present invention can be a cylinder or a combination of a cylinder and related components, which is a common technical means and will not be described in detail here.

[0042] Furthermore, due to space limitations, it is not possible to achieve expansion and contraction by means of fixed claws and pull rods. Also, since the air claws adopt a multi-point fixing method, the outer periphery of the short tube is subjected to uneven force and is prone to dents. In particular, when the angle changes during bending, it is more likely to cause deformation of the outer periphery of the short tube. Therefore, this embodiment adopts another method, specifically including a cylinder 5341, an air cylinder 11 5342 is provided on the outside of the cylinder 5341, and the output end of the cylinder 11 5342 extends into the cylinder 5341. A conical groove 5343 is formed in the cylinder 5341, and the opening of the conical groove 5343 gradually expands outward. The inner wall of the conical groove 5343 is provided with a ring array of several movable plates 5344, that is, the several movable plates 5344 are arranged in an inclined manner. shaped array arrangement, and several movable plates 5344 are arranged close to each other, and a circular movable block 2 5345 connected to the output end of cylinder 11 5342 is provided in the cylinder 5341, and one end of the movable plate 5344 is clamped with the movable block, and the clamping method adopts the method of annular flange 5348 and arc-shaped groove 5349. The tight connection between several movable plates 5344 limits it from moving left and right, but it can float up and down, but the arc-shaped groove 5349 and the annular flange 5348 will not be separated, and the other end extends out of the cylinder 5341 and forms a fixed position 2 5346. There is a gap 5347 between several movable plates 5344 near one end of the movable block. Preferably, when there is a gap 5347 at one end, the part extending out of the fixed cylinder 534 is closed.

[0043] The second fixing position 5346 is used to clamp and fix the end of the short tube. Before clamping, the inner diameter of the second fixing position 5346 needs to be expanded. When it is in action, the cylinder eleven 5342 pushes the movable block forward. At this time, there is a small gap 5347 between the movable plate 5344 and the inner wall of the conical groove 5343, so that the movable plate 5344 has floating space. When the short tube enters, these floating spaces can be used to make the inner diameter of the second fixing position 5346 adaptable and adjusted so that the short tube can enter smoothly. It should be noted that the floating margin is very small, and the entrance of the second fixing position 5346 is trumpet-shaped, so that several movable plates 5344 will not deviate. In addition, in order to achieve "conical" distribution and "clamping", several movable plates 5344 are not straight, but have an arc. If the entrance of the second fixing position 5346 is expanded, the inner diameter of the "circle" enclosed at the other end will become smaller. Therefore, it is very important to provide a gap 5347 between the adjacent movable plates 5344 at the other end to provide space for movement.

[0044] After the short tube enters the fixed position 2 5346, the cylinder 11 5342 pulls the movable block backward, and all the movable plates 5344 follow and come into contact with the inner wall of the conical groove 5343, fixing it at the inner diameter of the fixed position 2 5346 and clamping the end of the short tube.

[0045] One embodiment of the acquisition component 52 of the present invention specifically includes a conveying channel 521. Along the extension direction of the conveying channel 521, a plurality of rollers 522 are provided on both sides thereof. One end of the conveying channel 521 is close to the press-fit connection component 51, and the other end is provided with a push plate 523, which can abut against the end of the main pipe. The push plate 523 is connected to the cylinder 12 524, and the push plate 523 is driven by the cylinder 12 524 to move toward the press-fit connection component 51 and abut against the main pipe to push it to move.

[0046] Preferably, the end surface of the push plate 523 is further provided with a contoured block 525 adapted to the end cover, which can enter the end cover to better apply external force and prevent the main pipe from being deformed.

[0047] In the embodiment of the present invention, a detection device 55 for detecting cracks in the short tube is also included.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
