Description

Technical Field

[0001] The utility model relates to the technical field of expansion joint processing, in particular to a cutting and forming tooling for expansion joints. Background Art

[0002] An expansion joint, also known as a compensator or expansion joint, is an elastic element used to relieve stress and deformation caused by factors such as temperature changes and mechanical vibrations in pipelines, containers or equipment. In various industrial pipeline systems, expansion joints play a crucial role, especially in environments with large temperature fluctuations. During the manufacturing process of expansion joints, precise cutting of the skin material is required to ensure that the shape and dimensions of the expansion joints meet the design requirements.

[0003] When the material plate moves to below the cutting head on the surface of the conveying device during cutting, the position of the material plate is likely to shift or rotate, resulting in inaccurate cutting. This may lead to excessive or insufficient cutting of the material, increasing waste of raw materials. At the same time, unnecessary movement may occur during the cutting process, resulting in an uneven cutting line and affecting the shape and dimensional accuracy of the expansion joint.

[0028] Referring to Figures 1-4 , the present utility model provides an expansion joint cutting and forming tooling, including:

[0029] A main body unit 100, including a transfer table 101, a controller 102 is installed on one side of the transfer table 101, two sets of sliding rails 103 are installed on the upper surface of the transfer table 101, and a support frame is slidably connected between the sliding rails 103. The controller 102 is electrically connected to the sliding rails 103 to control the flexible movement of the support frame on the surface of the sliding rails 103. A laser cutting head 104 is installed on one side of the support frame;

[0030] A positioning unit 200, including two sets of side fixing plates 201 fixedly connected to the upper surface of the transfer table 101, and support plates are fixedly connected to the upper sides of the side fixing plates 201. An fixing plate 202 is fixedly connected between the two sets of support plates, and an electric push rod 203 is fixedly connected to the middle of the fixing plate 202. The electric push rod 203 is electrically connected to the controller 102. A fixed seat 204 is fixedly connected to the output end shaft of the electric push rod 203, and a bidirectional threaded rod 205 is rotatably connected inside the fixed seat 204. Threaded cylinders 206 are rotatably connected to the surfaces of both ends of the bidirectional threaded rod 205 through threads, and limit assemblies 207 are arranged on the upper sides of the threaded cylinders 206. Intercepting plates 209 are fixedly connected to the lower surfaces of the two sets of threaded cylinders 206. Guiding assemblies 212 are arranged on the sides of the two sets of side fixing plates 201 close to each other.

[0031] Among them, both sets of limiting components 207 include limiting rods 207a fixedly connected to the threaded tube 206, and the lower side surface of the fixed plate 202 is provided with limiting grooves 207b, and the inner wall surface of the limiting grooves 207b is slidably connected to the two sets of limiting rods 207a, which has a limiting effect on the threaded tube 206.

[0032] Furthermore, the two sets of intercepting plates 209 are fixedly connected to the opposite sides with positioning plates 210, and the positioning plates 210 are arc-shaped on the sides close to the laser cutting head 104, which have a guiding function, so that the material plate will not be deflected and fits tightly with the intercepting plate 209.

[0033] Furthermore, both groups of guide assemblies 212 include a guide seat 212a movably connected to the surface of the conveying platform 101, and the sides of the guide seats 212a that are close to each other are rotatably connected to multiple groups of rollers 212c, and the sides of the two groups of guide seats 212a that are separated from each other are rotatably connected to threaded screws 212b, and the threaded screws 212b are threadedly connected to the side fixing plates 201, and the sides of the two groups of guide seats 212a that are separated from each other are fixedly connected to sliding rods, and the sliding rods are slidably connected to the side fixing plates 201. The threaded rotating threaded screws 212b can enable the guide seats 212a to move on the surface of the conveying platform 101 with the limiting cooperation of the sliding rods, thereby allowing the multiple groups of rollers 212c to limit the movement of the material plate, so that the material plate can move smoothly on the surface of the conveying platform 101.

[0034] Furthermore, the ends of the two sets of guide seats 212a away from the fixed plate 202 are fixedly connected with the guide seats 212a, and one side of the guide plate 212d is inclined to have a guiding function, so that the material plate can move to the surface of the multiple sets of rollers 212c.

[0035] Furthermore, both ends of the bidirectional threaded rod 205 are fixedly connected with a fixing block 208, and the surface of the fixing block 208 is fixedly connected with multiple sets of torsion rods for manual holding, thereby improving the convenience of the staff in rotating the bidirectional threaded rod 205.

[0036] During use, according to the specifications of the material plate, manually rotate the threaded screw rod 212b. The guide seat 212a rotatably connected to the threaded screw rod 212b moves under the limiting action of the slide rod, driving a plurality of rollers 212c rotatably connected to the guide seat 212a to move on the surface of the transfer table 101 and fit with the material plate. Then, manually twist the fixing block 208 to drive the bidirectional threaded rod 205 to rotate inside the fixed seat 204, so that the threaded cylinders 206 move towards each other under the limiting action of the limiting rods 207a and the limiting grooves 207b. The intercepting plate 209 fixedly connected to the threaded cylinder 206 starts to move synchronously, and the positioning plate 210 fixedly connected to the intercepting plate 209 moves on the surface of the transfer table 101. During cutting, operate the controller 102 to control the electric push rod 203 to push the fixed seat 204 downward, so that the threaded cylinder 206 drives the intercepting plate 209 and the positioning plate 210 to intercept and position the material plate, facilitating the laser cutting head 104 to cut.
