Technical field:

[0001] The present application relates to the technical field of pre-pressing tooling, and in particular to a cushion belt pre-pressing tooling. Background technology:

[0002] The cushion belt is located between the tank truck frame and the tank body, which can disperse the stress on the bottom of the tank body and prevent stress concentration from causing the tank body to rupture.

[0003] The cushion belt comprises an integrally formed belt body, an arc-shaped transition section and a spherical surface. The spherical surface is fitted on the head of the can body, and the belt body is fitted on the can body. The existing can bodies generally have the same head but different curvatures of the can body.

[0004] In the traditional pad processing, the steel plate needs to be placed on the tank body, and then the worker uses the high temperature of the spray gun to make the steel plate deform easily, and then the worker uses a hammer and other tools to process the steel plate to ensure that the steel plate is processed into a pad that fits the curvature of the tank body. However, the use of the spray gun will produce a lot of smoke that affects the health of the workers, and improper operation during use may cause safety accidents. Moreover, this processing method has high labor intensity, low work efficiency, and may cause damage to the tank body, which cannot meet the existing work safety and environmental protection requirements. Utility model content:

[0005] In order to solve the above technical problems, the utility model provides a cushion belt pre-pressing tooling, which solves the technical problems that there are safety hazards in the manual processing of cushion belts, and the labor intensity is high, the work efficiency is low, and it may also cause damage to the tank body.

[0026] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0027] The cushion belt pre-pressing tooling comprises a frame 1, a mounting frame 2 is arranged on one side of the frame 1 in a fixed structure manner, and a first hydraulic cylinder 3 and a second hydraulic cylinder 4 are arranged on the mounting frame 2 in a fixed structure manner in the vertical direction; the hydraulic cylinders are installed vertically to ensure that the movement trajectory of the piston rod is vertical and no deviation occurs when squeezing the steel plate below.

[0028] Furthermore, the first hydraulic cylinder 3 is connected to the first pressing piece 6 having an arc structure at the bottom, and the first pressing piece 6 is located above the middle of the two cylindrical tubes A9 or the two cylindrical tubes B13, the two cylindrical tubes A9 are arranged in parallel and spaced apart on the upper end surface of the rotating frame 5, and the two cylindrical tubes B13 are arranged in parallel and spaced apart on the lower end surface of the rotating frame 5, and the steel plate placed between the two cylindrical tubes A9 or the two cylindrical tubes B13 is extruded through the arc structure at the bottom of the first pressing piece 6, and finally pressed into a cushion belt that meets the curvature requirements of the tank body; and the distance between the two cylindrical tubes B1 is different from the distance between the two cylindrical tubes A, so that belts with different curvatures can be extruded to adapt to tank bodies with different curvatures.

[0029] Specifically, a rotating shaft 11 is arranged on both sides of the rotating frame 5 in a fixed structure manner. The rotating shaft 11 is inserted into the bearing seat 12. The bearing seat 12 is arranged on the frame 1 in a fixed structure manner. When it is stationary, the rotating shaft 11 can provide support for the rotating frame 5. When switching the cylindrical tube A9 or the cylindrical tube B13, the rotating frame 5 can be driven to rotate by the rotation of the rotating shaft 11. The switching of the cylindrical tube A9 or the cylindrical tube B13 is realized by the rotation of the rotating frame 5 to process the belt body with different curvatures.

[0030] It needs to be explained that the arc mold 7 is arranged in a fixed structure on the frame 1 on the left side of the rotating frame 5, and the upper end surface of the arc mold 7 is provided with a spherical mold cavity and an arc mold cavity connected to each other; the second pressing piece 8 is arranged directly above the arc mold 7 and is connected to the second hydraulic cylinder 4 in a fixed structure, and the lower end surface of the second pressing piece 8 is adapted to the spherical mold cavity and the arc mold cavity; the first pressing piece 5 and the second pressing piece 8 are started at the same time, so that the cushion belt can be formed in one piece, saving pressing time and improving work efficiency.

[0031] It should be noted that the locking device includes a tightening cylinder 14, a locking pin 15 and a locking seat 10. The tightening cylinder 14 is connected to the frame 1, and the driving shaft of the tightening cylinder 14 is fixedly connected to the locking pin 15. The locking pin 15 cooperates with the locking seat 10 in a plug-in structure. The locking seat 10 is arranged on the side elevation of the rotating frame 5 in a fixed structure. The inner cavity of the locking seat 10 is arranged in a conical structure. The locking pin 15 is adapted to the inner cavity of the locking seat 10. The right diameter of the conical inner cavity is larger than the left diameter, so that the locking pin 15 can be more easily inserted into the locking seat 10; after the rotating frame 5 rotates the cylindrical tube A9 or the cylindrical tube B13 to just below the first pressing piece 6, the locking pin 15 can be inserted into the inner cavity of the locking seat 10 to fix the rotating frame 5 and prevent the rotating frame 5 from rotating during the pressing process.

[0032] Preferably, the mounting frame 2 is L-shaped, and the two first hydraulic cylinders 3 are both arranged in the horizontal section of the mounting frame 2, and the first hydraulic cylinder 3 is hingedly connected to the first pressure piece 6; the use of two hydraulic cylinders can disperse and bear the force, so that the mounting frame 2 can withstand greater pressure, and the two hydraulic cylinders can better maintain the balance of the first pressure piece 6 to avoid shaking of the first pressure piece 6.

[0033] The working principle and working process of the utility model are as follows:

[0034] Start the first hydraulic cylinder 3 and the second hydraulic cylinder 4 to drive the first pressing piece 6 and the second pressing piece 8 to rise, leaving space for operation, and then rotate the rotating shaft 11. The rotation of the rotating shaft 11 drives the rotating frame 5 to rotate, so that the cylindrical tube A9 or the cylindrical tube B13 rotates to the bottom of the first pressing piece 6, and then aligns the locking pin 15 with the inner cavity of the locking seat 10, starts the tightening cylinder 14, drives the transmission shaft to extend, and drives the locking pin 15 to be inserted into the conical cavity. After completing the locking of the rotating frame, place the steel plate on the frame 1, adjust the position until the steel plate is completely placed within the operating range of the rotating frame 5 and the arc mold 7, and then start the first hydraulic cylinder 3 and the second hydraulic cylinder 4 to drive the first pressing piece 6 and the second pressing piece 8 to descend, and press the steel plate.
