Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to a bending device for the production of metal pipe fittings. Background Technology

[0002] Metal pipe fittings are widely used in industrial production, especially in pipeline connection and gas transportation. Traditional metal pipe bending methods often suffer from low precision, low efficiency, and easy damage. To solve these problems, a bending device for metal pipe fitting production has been developed. Through optimized design and technological innovation, it can improve bending accuracy, shorten the production cycle, and effectively reduce equipment failure rate, meeting the needs of modern industry for efficient and precise production.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing bending devices for metal pipe production cannot accurately adjust the bending angle and shape of metal pipes. Due to the inaccuracy of the bending angle and shape, the shape and size of the final product may not meet the design requirements, affecting the appearance quality and performance of the product. The inability to accurately adjust the bending angle and shape means that more trial and error processes may be required, increasing production time and costs. In addition, for some special shape or angle requirements, additional manual adjustments or secondary processing may be required, further reducing production efficiency.

[0004] Therefore, this utility model proposes a bending device for the production of metal pipe fittings to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a bending device for the production of metal pipe fittings.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a bending device for producing metal pipe fittings, comprising:

[0007] Base plate;

[0008] A bending angle adjustment assembly is placed on top of a base plate. The bending angle adjustment assembly includes a first support plate fixed to the top of the base plate, a support frame fixedly connected to the first support plate, a transmission motor installed at the bottom of the support frame, a rotating block fixedly connected to the output end of the transmission motor, a limit post fixedly connected to the rotating block, a limit plate provided on the limit post, a limit groove formed on the side of the limit plate near the limit post, the limit post slidably connected in the limit groove, a rack fixedly connected to the limit plate, a gear meshing on the rack, the gear rotatably connected to the bottom of the first support plate, a slider fixedly connected to the top of the rack, a fixing block provided on the slider, a connecting block fixedly connected to the top of the slider, a support seat fixedly connected to the top of the connecting block, a roller rotatably connected to the side of the support seat near the top, and a limit seat fixedly connected to the top of the first support plate.

[0009] A bending buffer assembly is placed on the side of the first support plate near the top of the limiting seat. The bending buffer assembly includes a bracket fixed on the first support plate, a hydraulic push rod is installed on the top of the bracket, and a bending head is provided on the output end of the hydraulic push rod.

[0010] Furthermore, a first groove is provided on the side of the fixed block near the slider, and the slider is slidably connected in the first groove.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, since the first groove is provided on the side of the fixed block near the slider, and the slider is slidably connected in the first groove, the slider can make smooth linear movement on the fixed block, thereby meeting the needs of different position adjustments.

[0012] Furthermore, a second groove is provided on the side of the first support plate near the connecting block, and the connecting block is slidably connected in the second groove.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, since a second sliding groove is provided on the side of the first support plate near the connecting block, and the connecting block is slidably connected in the second sliding groove, the connecting block can make smooth linear movement on the first support plate, thereby meeting the needs of adjustment in different positions.

[0014] Furthermore, a second support plate is fixedly connected to the output end of the hydraulic push rod, and a limit rod is fixedly connected to the bottom of the second support plate.

[0015] The beneficial effects of adopting the above-mentioned further solution are: since the output end of the hydraulic push rod is fixedly connected to the second support plate, it ensures that the hydraulic push rod can stably transmit force during operation; since the bottom of the second support plate is fixedly connected to the limit rod, the limit rod is used to limit the movement range of the connecting plate and plays a limiting role in the movement of the connecting plate.

[0016] Furthermore, a connecting plate is slidably connected to the limiting rod, a first limiting block is fixedly connected to the bottom of the limiting rod, and a second limiting block is slidably connected to the limiting rod.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: Since the connecting plate is slidably connected to the limiting rod, the connecting plate can move freely on the limiting rod; Since the bottom of the limiting rod is fixedly connected to the first limiting block, the limiting block is used to limit the lowest position of the connecting plate to ensure that it will not drop excessively during the bending process; Since the limiting rod is slidably connected to the second limiting block, the limiting block can be adjusted in position as needed to limit the highest position of the connecting plate, thereby further controlling the movement range of the bending head.

[0018] Furthermore, a telescopic spring is provided on the limiting rod, one end of which is fixedly connected to the connecting plate, and the other end of which is fixedly connected to the second limiting block.

[0019] The beneficial effects of adopting the above-mentioned further solution are as follows: Since the limit rod is equipped with a telescopic spring, and one end of the telescopic spring is fixedly connected to the connecting plate, and the other end of the telescopic spring is fixedly connected to the second limit block, the telescopic spring can move in and out of the limit rod, thereby providing a certain elastic force, which plays a buffering role during the bending operation of metal pipe fittings and prevents the workpiece from being indented.

[0020] Furthermore, the bending head is fixedly connected to the bottom of the connecting plate.

[0021] The beneficial effect of adopting the above-mentioned further solution is that, since the bending head is fixedly connected to the bottom of the connecting plate, the bending head is used to perform bending operations on metal pipes.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, the drive motor is fixed on the support frame, and its output end is connected to the rotating block. The rotating block further cooperates with the limiting post and the limiting plate, so that the limiting plate drives the rack to move. Since the rack meshes with the gear, and the gear is rotatably connected to the bottom of the support frame, when the rack moves, it will drive the gear to rotate, so that the gear can drive the two meshing racks to move in opposite directions. The movement of the rack is transmitted to the connecting block through the slider. Since the support base is fixed on the connecting block, the rollers set on the support base can move, thereby enabling precise adjustment of the distance between the rollers, ensuring that the metal pipe can be precisely bent according to the predetermined angle and shape.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-4 As shown, this embodiment provides a technical solution: a bending device for producing metal pipe fittings, comprising:

[0034] Base plate 1;

[0035] The bending angle adjustment component 2 is located on the top of the base plate 1. The bending angle adjustment component 2 includes a first support plate 21 fixed to the top of the base plate 1. A support frame 22 is fixedly connected to the first support plate 21. A drive motor 23 is installed at the bottom of the support frame 22. A rotating block 24 is fixedly connected to the output end of the drive motor 23. A limit post 25 is fixedly connected to the rotating block 24. A limit plate 26 is provided on the limit post 25. A limit groove 27 is formed on the side of the limit plate 26 near the limit post 25. The limit post 25 slides... A rack 28 is fixedly connected to the limiting plate 26 within the limiting groove 27. A gear 29 meshes with the rack 28. The gear 29 is rotatably connected to the bottom of the first support plate 21. A slider 210 is fixedly connected to the top of the rack 28. A fixing block 211 is provided on the slider 210. A connecting block 214 is fixedly connected to the top of the slider 210. A support base 215 is fixedly connected to the top of the connecting block 214. A roller 216 is rotatably connected to the support base 215 near the top. A limiting seat 217 is fixedly connected to the top of the first support plate 21.

[0036] The bending buffer assembly 3 is placed on the first support plate 21 near the top of the limiting seat 217. The bending buffer assembly 3 includes a bracket 31 fixed on the first support plate 21. A hydraulic push rod 32 is installed on the top of the bracket 31. A bending head 39 is provided on the output end of the hydraulic push rod 32. The drive motor 23 is fixed on the support frame 22, and its output end is connected to the rotating block 24. The rotating block 24 further cooperates with the limiting post 25 and the limiting plate 26, so that the limiting plate 26 drives the rack 28 to move. Since the rack 28 meshes with the gear 29... The gear 29 is rotatably connected to the bottom of the support frame 22. When the rack 28 moves, it drives the gear 29 to rotate, so that the gear 29 can drive the two meshing racks 28 to move in opposite directions. The movement of the racks 28 is transmitted to the connecting block 214 through the slider 210. Since the support base 215 is fixed on the connecting block 214, the rollers 216 set on the support base 215 can move, thereby enabling precise adjustment of the distance between the rollers 216, ensuring that the metal pipe can be precisely bent according to the predetermined angle and shape.

[0037] The above solutions also have the problem that they cannot provide sufficient cushioning for the metal pipes during bending operations, such as... Figures 1-3 As shown: A first groove 212 is provided on the side of the fixed block 211 near the slider 210. The slider 210 is slidably connected in the first groove 212. Because the first groove 212 is provided on the side of the fixed block 211 near the slider 210, and the slider 210 is slidably connected in the first groove 212, the slider 210 can make smooth linear movement on the fixed block 211, thereby meeting the needs of different position adjustments. A second groove 213 is provided on the side of the first support plate 21 near the connecting block 214. The connecting block 214 is slidably connected in the second groove 213. Because the second groove 213 is provided on the side of the first support plate 21 near the connecting block 214, and the connecting block 214 is slidably connected in the second groove 213, the connecting block 214 can make smooth linear movement on the first support plate 21, thereby meeting the needs of different position adjustments.

[0038] like Figure 1 as well as Figure 4As shown, a second support plate 33 is fixedly connected to the output end of the hydraulic push rod 32. A limit rod 34 is fixedly connected to the bottom of the second support plate 33. Because the output end of the hydraulic push rod 32 is fixedly connected to the second support plate 33, it ensures that the hydraulic push rod 32 can stably transmit force during operation. The limit rod 34, fixedly connected to the bottom of the second support plate 33, limits the movement range of the connecting plate 35, thus limiting its movement. The connecting plate 35 is slidably connected to the limit rod 34. A first limit block 36 is fixedly connected to the bottom of the limit rod 34, and a second limit block 37 is slidably connected to the limit rod 34. Because the connecting plate 35 is slidably connected to the limit rod 34, the connecting plate 35 can move freely on the limit rod 34. The first limit block 36, fixedly connected to the bottom of the limit rod 34, limits the lowest position of the connecting plate 35, ensuring that it does not descend excessively during bending. A second limiting block 37 is slidably connected to the limiting rod 34. The limiting block can be adjusted as needed to limit the highest position of the connecting plate 35 and further control the movement range of the bending head 39. A telescopic spring 38 is provided on the limiting rod 34. One end of the telescopic spring 38 is fixedly connected to the connecting plate 35, and the other end of the telescopic spring 38 is fixedly connected to the second limiting block 37. Because the limiting rod 34 is provided with a telescopic spring 38, and one end of the telescopic spring 38 is fixedly connected to the connecting plate 35, and the other end of the telescopic spring 38 is fixedly connected to the second limiting block 37, the telescopic spring 38 can move in and out on the limiting rod 34, thereby providing a certain elastic force and playing a buffering role during the bending operation of metal pipes to prevent the workpiece from being indented. The bending head 39 is fixedly connected to the bottom of the connecting plate 35. Because the bending head 39 is fixedly connected to the bottom of the connecting plate 35, the bending head 39 is used to perform bending operations on metal pipes.

[0039] Working principle:

[0040] like Figures 1-4As shown, the drive motor 23 is fixed on the support frame 22, and its output end is connected to the rotating block 24. The rotating block 24 further cooperates with the limiting post 25 and the limiting plate 26, so that the limiting plate 26 drives the rack 28 to move. Since the rack 28 meshes with the gear 29, and the gear 29 is rotatably connected to the bottom of the support frame 22, when the rack 28 moves, it will drive the gear 29 to rotate, so that the gear 29 can drive the two meshing racks 28 to move in opposite directions. The movement of the rack 28 is then transmitted to the connecting block 214 through the slider 210. Since the support base 215 is fixed on the connecting block 214, the roller 216 set on the support base 215 moves, thereby enabling precise movement. Adjusting the distance between rollers 216 ensures that the metal pipe can be precisely bent according to the predetermined angle and shape. Then, the metal pipe is placed on rollers 216. When the hydraulic push rod 32 is activated, its output end pushes the second support plate 33 downward. Since the limiting rod 34 is fixedly connected to the second support plate 33, the limiting rod 34 also moves downward. When the bending head 39 bends the metal pipe, the connecting plate 35 slides on the limiting rod 34 and is subjected to the force of the telescopic spring 38. As the hydraulic push rod 32 continues to push, the connecting plate 35 gradually approaches the first limiting block 36, which buffers the bending of the metal pipe and prevents excessive pressure from damaging the metal pipe.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
