Description

Technical Field

[0001] This invention relates to the technical field of metal bellows, and specifically to a device for blanking corrugated sheets for welding metal bellows. Background Technology

[0002] When blanking the corrugated sheets of a metal corrugated tube, the metal corrugated tube needs to be cut to facilitate control of its length.

[0003] According to the patent document with application number CN201811167522.5, a blanking device for welded metal corrugated pipes includes a support platform, a fixed box, a cutting mechanism, a placement mechanism, a feeding mechanism, a fixing mechanism, a lifting mechanism, and a grinding wheel. The cutting mechanism has symmetrically installed fixing mechanisms on its side walls. When the metal corrugated pipe enters the fixed box, the cutting mechanism moves downwards, and the fixing mechanisms squeeze the metal corrugated pipe, gradually expanding the fixing mechanisms. The squeezing force of the fixing mechanisms increases, fixing the metal corrugated pipe in place. The cutting mechanism cuts between the two fixing mechanisms to prevent the metal corrugated pipe from shaking during cutting, thus ensuring a flush cut surface. A grinding wheel is installed on the side wall of the cutting mechanism, with the thickness of the grinding wheel increasing gradually from its periphery to its center. As the cutting mechanism enters the metal corrugated pipe, the grinding wheel rotates closer and closer to the cut surface of the metal corrugated pipe, smoothing the cut surface.

[0004] Currently, the corrugated sheet unloading device for welded metal corrugated pipes often moves the corrugated pipe to the vicinity of the cutting machine by pushing it with a push rod or manually. In this method, the corrugated pipe is only subjected to force at one end, which affects the cutting effect and makes the sliding unstable. Summary of the Invention

[0005] The present invention mainly provides a corrugated sheet blanking device for welding metal corrugated pipes to solve the technical problems mentioned in the background art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A corrugated sheet blanking device for welding metal corrugated pipes includes a support platform, a cutting machine connected to the upper surface of the support platform, a feeding mechanism on one side of the cutting machine, and a discharging mechanism on the other side of the cutting machine.

[0008] The feeding mechanism and the discharging mechanism have the same structure. The feeding mechanism includes a corrugated pipe slide that is slidably connected to the top of the support platform, an active pushing component located outside the corrugated pipe slide away from the cutting machine, and a driven component located at the other end of the corrugated pipe slide.

[0009] Multiple helical actuators are connected between the active driving component and the driven component, and the helical actuators are used to drive the welded metal bellows.

[0010] Furthermore, the active pushing component includes a support frame connected to the upper surface of the support platform. An L-shaped sliding support plate is slidably connected to the inner top of the support frame. A plurality of first motors connected to one end of the helical pusher are connected to one side surface of the L-shaped sliding support plate. In this invention, the first motor drives the helical pusher to rotate. Through the rotation of the helical pusher and its pushing against the metal bellows, the metal bellows is driven to slide within the bellows track.

[0011] Furthermore, a first electric push rod is connected to the upper surface of the support frame. The rod of the first electric push rod extends into the support frame and connects to the top of the L-shaped sliding support plate. In this invention, the L-shaped sliding support plate is driven to rise and fall by the first electric push rod so that the L-shaped sliding support plate can slide on the support frame.

[0012] Furthermore, the driven component includes a bracket connected to the upper surface of the support platform, and an L-shaped sliding support plate is slidably connected inside the bracket. The L-shaped sliding support plate is rotatably connected to one end of the helical pusher. In this invention, the sliding of the L-shaped sliding support plate within the bracket allows the L-shaped sliding support plate to cooperate with the lifting and lowering of the L-shaped sliding support plate, thereby keeping the helical pusher horizontal.

[0013] Furthermore, a second electric push rod is connected to the upper surface of the bracket. One end of the rod of the second electric push rod extends into the interior of the bracket and connects to the top of the L-shaped sliding support plate. In this invention, the L-shaped sliding support plate is raised and lowered by the second electric push rod so that the L-shaped sliding support plate slides inside the bracket.

[0014] Furthermore, protruding plates are connected to both sides of the support platform, and a lead screw is rotatably connected between the two protruding plates. A second motor is connected to one side of the protruding plate, and the output shaft of the second motor is connected to one end of the lead screw. In this invention, the protruding plates provide support for the lead screw and the second motor, and the second motor drives the lead screw to rotate so that when the lead screw rotates, it can drive the translation plate connected to it to translate, thereby driving the bracket connected to the translation plate to translate.

[0015] Furthermore, the outer surfaces of both ends of the lead screw are provided with threads, and the two ends of the lead screw have opposite rotation directions. In this invention, since the threads at both ends of the lead screw have opposite rotation directions, the two supports are kept away from each other or close to each other.

[0016] Furthermore, the outer surface of the lead screw is connected to a translation plate via a lead nut. The translation plate is connected to the outer surface of the adjacent bracket. In this invention, the bracket is driven to move along with the translation plate by the connection between the translation plate and the bracket.

[0017] Furthermore, slide rails are connected to both sides of the support platform. The slide rails are located above the lead screw and are slidably connected to the translation plate. In this invention, the slide rails guide the bracket to slide stably.

[0018] Furthermore, the spiral pusher has horizontal connecting ends at both ends. One end of the spiral pusher is connected to the output shaft of the first motor through the horizontal connecting end, and the other end of the spiral pusher is rotatably connected to the L-shaped sliding support plate through the horizontal connecting end. In this invention, the spiral pusher is connected to the L-shaped sliding support plate and the first motor through the spiral pusher.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] Firstly, the present invention uses a first motor to drive a spiral pusher to rotate. The rotation of the spiral pusher and its push against the metal bellows cause the metal bellows to slide within the bellows slide. Through the contact between the spiral pusher and the metal bellows, the metal bellows is stably transported and output within the bellows slide, thus facilitating the cutting of the metal bellows by the cutting machine.

[0021] Secondly, the present invention provides support for the lead screw and the second motor through the convex plate. The second motor drives the lead screw to rotate, so that when the lead screw rotates, it can drive the translation plate connected to it to translate, and then drive the bracket connected to the translation plate to translate, so as to control the pitch of the screw pusher. In this way, the blanking device can adapt to different metal corrugated pipes and improve the applicability of the blanking device.

[0022] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0028] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] For an example, please refer to the appendix. Figure 1-4 A corrugated sheet blanking device for welding metal corrugated pipes includes a support platform 10, a cutting machine 20 connected to the upper surface of the support platform 10, a feeding mechanism 30 on one side of the cutting machine 20, and a discharging mechanism 40 on the other side of the cutting machine 20.

[0032] The feeding mechanism 30 and the discharging mechanism 40 have the same structure. The feeding mechanism 30 includes a corrugated pipe slide 31 slidably connected to the top of the support platform 10, an active pushing component 32 located outside the corrugated pipe slide 31 away from the cutting machine 20, and a driven component 33 located at the other end of the corrugated pipe slide 31.

[0033] A plurality of spiral pushers 34 are connected between the active pusher component 32 and the driven component 33. The spiral pushers 34 are used to push the welded metal bellows.

[0034] For details, please refer to the appendix. Figure 1 and 2 The active pushing component 32 includes a support frame 321 connected to the upper surface of the support platform 10. An L-shaped sliding support plate 322 is slidably connected to the inner top of the support frame 321. A plurality of first motors 323 connected to one end of the spiral pusher 34 are connected to one side surface of the L-shaped sliding support plate 322.

[0035] The upper surface of the support frame 321 is connected to a first electric push rod 324, and the rod of the first electric push rod 324 extends into the support frame 321 and connects to the top of the L-shaped sliding support plate 322.

[0036] It should be noted that in this embodiment, the L-shaped sliding support plate 322 is slidable by the support 321, and the position of the first motor 323 is adjusted by the L-shaped sliding support plate 322. Since the first motor 323 is connected to the spiral pusher 34, the position of the spiral pusher 34 is adjusted so that the distance between the spiral pusher 34 and the support platform 10 matches the metal bellows.

[0037] The first motor 323 drives the spiral pusher 34 to rotate. The rotation of the spiral pusher 34 and its push against the metal bellows cause the metal bellows to slide within the bellows slide 31.

[0038] Furthermore, the L-shaped sliding support plate 322 is raised and lowered by the first electric push rod 324 so that the L-shaped sliding support plate 322 can slide on the support frame 321.

[0039] For details, please refer to the appendix. Figure 1 and 2 The driven component 33 includes a bracket 331 connected to the upper surface of the support platform 10. An L-shaped sliding support plate 332 is slidably connected inside the bracket 331. The L-shaped sliding support plate 332 is rotatably connected to one end of the screw pusher 34.

[0040] The upper surface of the bracket 331 is connected to a second electric push rod 333, one end of the rod of the second electric push rod 333 extends into the interior of the bracket 331 and connects to the top of the L-shaped sliding support plate 332.

[0041] It should be noted that in this embodiment, the sliding of the L-shaped sliding support plate 332 within the bracket 331 allows the L-shaped sliding support plate 332 to cooperate with the lifting and lowering of the L-shaped sliding support plate 322, thereby keeping the spiral pusher 34 horizontal.

[0042] Furthermore, the L-shaped sliding support plate 332 is raised and lowered by the second electric push rod 333, so that the L-shaped sliding support plate 332 slides within the bracket 331.

[0043] For details, please refer to the appendix. Figure 1 and 2 The support platform 10 has protruding plates 11 connected to both sides, and a lead screw 12 is rotatably connected between the two protruding plates 11. A second motor 13 is connected to one side of the protruding plate 11, and the output shaft of the second motor 13 is connected to one end of the lead screw 12.

[0044] The outer surfaces of both ends of the lead screw 12 are provided with threads, and the two ends of the lead screw 12 are rotated in opposite directions;

[0045] The outer surface of the lead screw 12 is connected to a translation plate 14 via a lead nut, and the translation plate 14 is connected to the outer surface of the adjacent bracket 331;

[0046] It should be noted that in this embodiment, the convex plate 11 provides support for the lead screw 12 and the second motor 13. The second motor 13 drives the lead screw 12 to rotate, so that when the lead screw 12 rotates, it can drive the translation plate 14 connected to it to translate, and then drive the bracket 331 connected to the translation plate 14 to translate, so as to control the pitch of the screw pusher 34. In this way, the blanking device can adapt to different metal corrugated pipes and improve the applicability of the blanking device.

[0047] Furthermore, since the threads at both ends of the lead screw 12 rotate in opposite directions, the two supports 331 are either far apart or close together;

[0048] Furthermore, through the connection between the translation plate 14 and the bracket 331, the bracket 331 is driven to move along with the translation plate 14.

[0049] For details, please refer to the appendix. Figure 1 and 2 The two sides of the support platform 10 are connected to slide rails 15, which are located above the lead screw 12 and are slidably connected to the translation plate 14.

[0050] The spiral pusher 34 has horizontal connecting ends 341 at both ends. One end of the spiral pusher 34 is connected to the output shaft of the first motor 323 through the horizontal connecting end 341, and the other end of the spiral pusher 34 is rotatably connected to the L-shaped sliding support plate 332 through the horizontal connecting end 341.

[0051] It should be noted that, in this embodiment, the slide rail 15 guides the bracket 331 to slide stably;

[0052] Furthermore, the helical pusher 34 is connected to the L-shaped sliding support plate 332 and the first motor 323.

[0053] The specific operation method of this invention is as follows:

[0054] When using the corrugated sheet unloading device for welded metal corrugated pipes, one end of the welded metal corrugated pipe is guided to be placed in the corrugated pipe slide 31. The first motor 323 drives the spiral pusher 34 to rotate. Through the rotation of the spiral pusher 34 and its push against the metal corrugated pipe, the metal corrugated pipe is driven to slide in the corrugated pipe slide 31. Through the contact between the spiral pusher 34 and the metal corrugated pipe, the metal corrugated pipe is stably conveyed and output in the corrugated pipe slide 31, thereby facilitating the cutting of the metal corrugated pipe by the cutting machine 20.

[0055] The lead screw 12 and the second motor 13 are supported by the convex plate 11. The lead screw 12 is driven to rotate by the second motor 13, so that when the lead screw 12 rotates, it can drive the translation plate 14 connected to it to translate, and then drive the bracket 331 connected to the translation plate 14 to translate, so as to control the pitch of the screw pusher 34. In this way, the blanking device can adapt to different metal corrugated pipes and improve the applicability of the blanking device.

[0056] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
