Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe processing technology, specifically a corrugated pipe stretching table. Background Technology

[0002] In the production process of bellows, a stretching table is used to stretch and shape the bellows, ensuring that the dimensional accuracy and performance of the bellows meet the requirements. By precisely controlling the stretching ratio and stretching force, the quality and stability of the bellows can be improved, and the scrap rate can be reduced.

[0003] Currently, in existing technologies, some existing corrugated pipe stretching tables achieve clamping through simple bolt tightening. Operators find it difficult to accurately control the clamping force according to the specific conditions of the corrugated pipe, resulting in either excessive clamping force, causing deformation or even damage to the corrugated pipe at the clamping point, affecting its performance and subsequent use. In view of this, we propose a corrugated pipe stretching table. Utility Model Content

[0004] The main objective of this invention is to provide a corrugated pipe stretching table that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a bellows stretching table, comprising a stretching table, a driving assembly provided on the outer wall of the stretching table, a guide rod provided on the outer wall of the stretching table, a stretching seat slidably connected to the guide rod, the stretching seat being engaged with the bellows body via a clamping assembly, and a sliding limiting assembly provided inside the stretching seat. The clamping assembly includes:

[0006] A fixed shell is fixedly connected to the outer wall of the tension seat. A rotating plate is rotatably connected inside the fixed shell. A hinge seat is rotatably connected to the rotating plate. A threaded rod is threadedly connected to the hinge seat.

[0007] The handle is fixedly connected to the threaded rod, and the threaded rod is hinged to the connecting block of the rotating plate 2. The surfaces of the rotating plate 1 and the rotating plate 2 are provided with sliding grooves, and a limit rod is slidably connected in the sliding groove. A clamping block is fixedly connected to the limit rod.

[0008] Preferably, the drive assembly includes a rotating wheel rotatably connected to the protective shell. The rotating wheel is fixedly connected to a worm gear, which is meshed with a worm wheel. The worm wheel is fixedly connected to a gear, which is meshed with a rack. When the operator rotates the rotating wheel, the worm gear rotates accordingly. The rotation of the worm gear drives the worm wheel to rotate. Because the worm wheel and worm gear transmission has self-locking properties, the stability and accuracy of the transmission can be guaranteed. The rotation of the worm wheel drives the gear to rotate synchronously. When the gear rotates, it moves along the rack. The rack is fixedly connected to the tension seat, and the rack drives the tension seat to slide on the guide rod.

[0009] Preferably, the sliding limiting component includes a rotating groove, and the inner wall of the tension seat is provided with a rotating groove.

[0010] Preferably, the rotating groove has a movable groove, which is elastically connected to the sliding block by a spring. The sliding block can slide in a certain direction within the movable groove, and the spring will generate an elastic force on the sliding block.

[0011] Preferably, a limiting arc plate is fixedly connected to the outer wall of the sliding block, and a rotating cylinder is rotatably connected to the limiting arc plate. When the corrugated pipe body is inserted into the tension seat, it contacts the rotating cylinder.

[0012] Preferably, the rotating drum is provided in multiple sets. Since the corrugated pipe body has a certain dimensional deviation, the rotating drum can rotate around the connection point with the limiting arc plate, thereby adapting to the insertion of the corrugated pipe body, reducing the friction and resistance between the corrugated pipe body and the tension seat, and enabling the corrugated pipe body to be inserted more smoothly.

[0013] This utility model provides a bellows stretching table. It has the following beneficial effects:

[0014] (1) The bellows stretching table uses a clamping assembly to control the rotation of the threaded rod by turning the handle, thereby adjusting the clamping force of the clamping block. The operator can precisely adjust the clamping force according to factors such as the size and material of the bellows body to ensure the stability and reliability of the clamping. This adjustable clamping force can adapt to bellows of different specifications, avoiding deformation or damage to the bellows due to excessive clamping force, and also preventing the bellows from sliding during the stretching process due to insufficient clamping force, which would affect the stretching effect and accuracy.

[0015] (2) The bellows stretching table automatically adjusts the clamping force and limit range according to the outer diameter of the bellows body through the sliding limit component. When the size of the bellows body has a certain deviation, the bellows body can be adaptively clamped by the rotation of the drum and the elastic deformation of the spring, ensuring its stable fixation in the stretching seat. There is no need for frequent manual adjustment, which improves the versatility and ease of operation of the equipment. Attached Figure Description

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.

[0028] Please see Figures 1-7This utility model proposes a bellows stretching table, including a stretching table 1. A drive assembly 2 is provided on the outer wall of the stretching table 1. The drive assembly 2 includes a rotating wheel 201, which is rotatably connected to a protective shell. The rotating wheel 201 is fixedly connected to a worm gear 202, which is meshed with a worm wheel 203. The worm wheel 203 is fixedly connected to a gear 204, which is meshed with a rack 205. When the operator rotates the rotating wheel 201, the worm gear 202 rotates accordingly, driving the worm wheel 203 to rotate. Because the worm wheel 203 and worm gear 202 transmission has a self-locking property, the stability and accuracy of the transmission can be guaranteed. The rotation of the wheel will drive the gear 204 to rotate synchronously. When the gear 204 rotates, it will move along the rack 205. The rack 205 is fixedly connected to the tension seat 3. The rack 205 will drive the tension seat 3 to slide on the guide rod 301. The outer wall of the tension table 1 is provided with the guide rod 301. The guide rod 301 is slidably connected to the tension seat 3. The tension seat 3 is engaged with the bellows body 4 through the clamping assembly 6. By controlling the rotation speed and number of revolutions of the wheel 201, the moving speed and stroke of the tension seat 3 can be precisely controlled, thereby achieving precise control of the degree of stretching of the bellows body 4. The tension seat 3 is provided with a sliding limit assembly 7. The clamping assembly 6 includes a fixed shell 61.

[0029] In this embodiment of the utility model, in order to achieve stable and adjustable clamping force, specifically, a fixed shell 61 is fixedly connected to the outer wall of the tension seat 3, a rotating plate 62 is rotatably connected inside the fixed shell 61, a hinge seat 63 is rotatably connected to the rotating plate 62, a threaded rod 64 is threadedly connected to the hinge seat 63, the rotation of the threaded rod 64 will cause the hinge seat 63 to move along the threaded rod 64, the threaded rod 64 is fixedly connected to the handle 65, the threaded rod 64 is hinged to the connecting block of the rotating plate 66, a sliding groove 67 is provided on the surface of both the rotating plate 62 and the rotating plate 66, a limit rod 68 is slidably connected in the sliding groove 67, a clamping block 69 is fixedly connected to the limit rod 68, the operator rotates the handle 65, the handle 65 drives the threaded rod 64 to rotate, and the clamping block 69 is used to contact and clamp the bellows body 4.

[0030] Furthermore, to improve the versatility and ease of operation of the equipment, specifically, the sliding limit assembly 7 includes a rotating groove 71. The inner wall of the tension seat 3 is provided with a rotating groove 71, and a movable groove 72 is provided in the rotating groove 71. The movable groove 72 is elastically connected to the sliding block 74 through a spring 73. The sliding block 74 can slide in a certain direction in the movable groove 72, and the spring 73 will generate an elastic force on the sliding block 74. The outer wall of the sliding block 74 is fixedly connected to a limiting arc plate 75, and the limiting arc plate 75 is rotatably connected to a rotating cylinder 76. When the corrugated pipe body 4 is inserted into the tension seat 3, it contacts the rotating cylinder 76. Multiple sets of rotating cylinders 76 are provided. Due to the certain dimensional deviation of the corrugated pipe body 4, the rotating cylinder 76 can rotate around the connection point with the limiting arc plate 75, thereby adapting to the insertion of the corrugated pipe body 4, reducing the friction and resistance between the corrugated pipe body 4 and the tension seat 3, and allowing the corrugated pipe body 4 to be inserted more smoothly.

[0031] In this invention, during use, when the bellows body 4 is inserted into the tension seat 3 and contacts the rotating drum 76, due to a certain dimensional deviation in the bellows body 4, the drum 76 can rotate around the connection point with the limiting arc plate 75, thereby accommodating the insertion of the bellows body 4, reducing friction and resistance between the bellows body 4 and the tension seat 3, and allowing the bellows body 4 to be inserted more smoothly. When it is necessary to clamp the bellows body 4, the operator turns the handle 65. The rotation of the threaded rod 64 causes the hinge seat 63 to move along the threaded rod 64. The movement of the hinge seat 63 will drive the rotating plate 1 62 and the rotating plate 2 66 to rotate relative to each other. The limiting rod 68 is fixedly connected to the clamping block 69, and the clamping block 69 will move along the sliding groove 67, thereby bringing the two clamping blocks 69 closer together to clamp the bellows body 4. When the appropriate clamping force is reached, the handle 65 is stopped, and the bellows body 4 is firmly clamped on the tension seat 3, ensuring the smooth progress of the tensile test production.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
