Description

Technical Field

[0001] The utility model belongs to the technical field of rubber hose production, in particular to a rubber hose production vulcanization device. Background Art

[0002] Hydraulic hose, also known as rubber-plastic hose, is a new type of hose used for conveying liquids such as petroleum-based and water-based liquids with a certain pressure and temperature. During the processing of the hose, the hose needs to be vulcanized, and vulcanization is the process of vulcanizing and molding using high-pressure steam at the time, temperature and pressure specified by the process. Therefore, the vulcanization of the hose requires a large amount of vulcanizing steam. Most of the hoses are now directly placed in the box when they are vulcanized, and the position of most nozzles used to spray vulcanizing steam is fixed, resulting in the hose only being subjected to vulcanizing steam in a fixed direction, which can easily cause uneven heating of the hose, thereby reducing the quality of the vulcanization of the hose.

[0003] For example, the existing Chinese publication number is: CN214872073U, a hose vulcanizing device, which: "comprising a reaction tank, the reaction tank is provided with an opening, the reaction tank is provided with a sealing plate for sealing the opening, the reaction tank is provided with two fixing mechanisms for fixing the two ends of the hose body, the fixing mechanism comprising a fixing plate and a fixing rod fixed on the fixing plate."

[0004] It can be seen that the cited patent document has the problem that the hose is easily heated unevenly. Utility Model Content

Detailed implementation manners

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0025] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figures shown in the present utility model, and are hereby explained together.

[0026] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0027] As Figures 1 to 5 shown, a rubber hose production vulcanization device includes a box body 1, the inner side wall of the box body 1 is welded with a bottom plate 2, the top surface of the bottom plate 2 is provided with a U-shaped movable block 3, the inner cavity of the bottom plate 2 is provided with a limit block 11 through a through hole, the movable block 3 is slidably sleeved on the periphery of the limit block 11, the bottom surface of the bottom plate 2 is installed with a cylinder 12 through a vertical plate, the piston rod of the cylinder 12 is connected with the movable block 3, by turning on the cylinder 12, the cylinder 12 can drive the movable block 3 to move, and the setting of the limit block 11 can improve the stability of the movable block 3 during movement.

[0028] The top surface of the movable block 3 is symmetric and longitudinally welded with two vertical plates 4. An upper arc-shaped diverter 7 is arranged between the two vertical plates 4. The inner bottom surface of the movable block 3 is provided with a lower arc-shaped diverter 8. The rubber hose to be vulcanized is located between the lower arc-shaped diverter 7 and the upper arc-shaped diverter 8. A number of nozzles 9 for spraying vulcanizing steam are equidistantly arranged on the inner side walls of the upper arc-shaped diverter 7 and the lower arc-shaped diverter 8. Both the upper arc-shaped diverter 7 and the lower arc-shaped diverter 8 are connected with a connecting pipe 10 for transporting vulcanizing steam. The two connecting pipes 10 are respectively externally connected to the vulcanizing steam, so that the two connecting pipes 10 can respectively transport the externally connected vulcanizing steam into the lower arc-shaped diverter 7 and the upper arc-shaped diverter 8, enabling the lower arc-shaped diverter 7 and the upper arc-shaped diverter 8 to disperse the vulcanizing steam to multiple nozzles 9 and spray it out. Since the lower arc-shaped diverter 7 and the upper arc-shaped diverter 8 are arranged in an arc shape and there are a number of nozzles 9, the multiple nozzles 9 can spray the vulcanizing steam at different angles respectively, enabling the peripheral side of the rubber hose to be subjected to vulcanizing steam at different angles. By cooperating with the movement of the movable block 3 driven by the cylinder 12, the multiple nozzles 9 can heat other parts of the peripheral side of the rubber hose, thereby heating the rubber hose comprehensively, reducing the situation of uneven heating of the rubber hose due to the fixed position of the nozzles 9, and improving the quality of vulcanizing the rubber hose.

[0029] Both of the two connecting pipes 10 are made of soft materials, similar to the existing telescopic pipes, and only need to ensure that the connecting pipes 10 can move along with the movable block 3 and transport the vulcanizing steam.

[0030] The top surface of the two vertical plates 4 is welded with a cross plate 5. The top surface of the cross plate 5 is provided with an electric push rod 6. The output end of the electric push rod 6 penetrates through the cross plate 5 and is connected to the upper arc-shaped diverter 7. Through the electric push rod 6, the upper arc-shaped diverter 7 can be driven to perform longitudinal reciprocating motion, thereby changing the distance between the upper arc-shaped diverter 7 and the lower arc-shaped diverter 8, facilitating the operation of the rubber hose located between the upper arc-shaped diverter 7 and the lower arc-shaped diverter 8 by personnel. Sliding blocks sleeved around the peripheral sides of the vertical plates 4 are welded on both side surfaces of the upper arc-shaped diverter 7, and the two sliding blocks can improve the stability of the longitudinal reciprocating motion of the upper arc-shaped diverter 7.

[0031] The top surface of the bottom plate 2 is welded with a mounting plate 13. A pipe core 14 for sleeving the rubber hose is welded on one side surface of the mounting plate 13, and the pipe core 14 is located between the upper arc-shaped diverter 7 and the lower arc-shaped diverter 8, enabling the rubber hose to be vulcanized to be sleeved around the peripheral side of the pipe core 14, facilitating the heating treatment.

[0032] On one side of the mounting plate 13, four rectangular blocks 15 are symmetrically mounted. On the opposite sides of two of the rectangular blocks 15, a bidirectional threaded rod 16 is rotatably connected. The top end of the bidirectional threaded rod 16 penetrates above the rectangular block 15 and is connected with a turning handle. A upper pressing block 17 and a lower pressing block 18 for fixing the rubber hose are sleeved on the circumferential side of the bidirectional threaded rod 16. When the rubber hose is sleeved on the circumferential side of the pipe core 14 and close to the mounting plate 13, the operator rotates the turning handle, which can drive the bidirectional threaded rod 16 to rotate, so that the bidirectional threaded rod 16 can drive the upper pressing block 17 and the lower pressing block 18 to move in opposite directions, and thus the rubber hose on the circumferential side of the pipe core 14 can be squeezed and fixed to avoid deviation during vulcanization.

[0033] On the opposite sides of the other two rectangular blocks 15, a limiting rod 19 is connected. The upper pressing block 17 and the lower pressing block 18 are respectively sleeved on the circumferential side of the limiting rod 19, and the limiting rod 19 can limit the movement of the upper pressing block 17 and the lower pressing block 18.

[0034] Working principle:

[0035] For this rubber hose production and vulcanization device, the rubber hose is sleeved on the circumferential side of the pipe core 14, and the turning handle is rotated. The turning handle drives the upper pressing block 17 and the lower pressing block 18 to move in opposite directions through the bidirectional threaded rod 16 to squeeze and fix the rubber hose. At this time, the external vulcanization steam is respectively conveyed into the upper arc-shaped diverter 7 and the lower arc-shaped diverter 8 through two connecting pipes 10. At the same time, the vulcanization steam is dispersed to multiple nozzles 9 and ejected. Since the rubber hose is located between the upper arc-shaped diverter 7 and the lower arc-shaped diverter 8, the multiple nozzles 9 can eject the vulcanization steam at different angles, so that the circumferential side of the rubber hose can be subjected to the vulcanization steam at different angles. At this time, the air cylinder 12 is started, and the air cylinder 12 drives the movable block 3 to perform a reciprocating motion, so that the upper arc-shaped diverter 7 and the lower arc-shaped diverter 8 can perform a reciprocating motion on the circumferential side of the rubber hose, thereby heating the rubber hose comprehensively, reducing the situation that the rubber hose is unevenly heated due to the fixed position of the nozzles 9, and improving the quality of vulcanizing the rubber hose.
