Description

Novel fixed thimble of plane vulcanizer

Technical Field

The utility model belongs to the technical field of plane vulcanizing machines, and particularly relates to a novel fixing thimble of a plane vulcanizing machine.

Background

In order to increase the heat exchange area of the tube, an aluminum plate is usually mounted on the tube as an extended heat exchange plate. At present, a powder-sprayed S-shaped aluminum pipe and an aluminum plate behind a peritoneum are connected together through vulcanization in a flat vulcanization mode. Because the product size is great, is difficult to fix, generally adopt the form of preparation mould groove to let return bend and aluminum plate can fix.

However, as the products are continuously pushed out and new products are produced, new molds need to be opened for new products, and the cost is high; and certain pressure can be generated in the vulcanization process, so that the aluminum pipe can be flattened, the contact area with the aluminum plate is increased, the position accuracy cannot be ensured due to the large groove, and the aluminum pipe can be extruded and deformed by the groove edge due to the small groove.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems and provide a novel plane vulcanizer fixing thimble.

The utility model realizes the purpose through the following technical scheme:

the utility model provides a novel fixed thimble of flat vulcanizer, includes the sleeve and locates lower steel sheet and aluminum pipe on the flat vulcanizer, the sleeve is located down the steel sheet, be equipped with the cylindricality cavity in the sleeve, be equipped with the cylindricality recess on the sleeve, the bottom and the cylindricality cavity of cylindricality recess are linked together, and the cross sectional dimension of cylindricality recess is less than the cross sectional dimension of cylindricality cavity, be equipped with the spring in the cylindricality cavity, the upside of spring is equipped with the thimble body, is close to the thimble body is equipped with the bellying with the one end of spring coupling side, the other end of thimble body is equipped with chamfer portion

As a further optimization scheme of the utility model, the lower steel plate is internally provided with a positioning hole for the sleeve to pass through, and the positioning hole is formed in the lower steel plate, so that the sleeve can be detachably arranged in the positioning hole, and the step of re-opening the die is saved.

As a further optimization scheme of the utility model, the sleeve is provided with a plurality of groups in the lower steel plate.

As a further optimization scheme of the utility model, the sleeves are uniformly distributed on the outer side of the aluminum pipe, the aluminum pipe is conveniently positioned by limiting the sleeves, and the aluminum pipe is prevented from being extruded and deformed when being flattened and deformed.

As a further optimized scheme of the utility model, the thimble body is telescopically arranged in the sleeve.

The utility model has the beneficial effects that: this novel fixed thimble of plane vulcanizer is through having seted up a plurality of groups locating hole on the steel sheet down, thereby make things convenient for location installation thimble body, can effectively avoid newly opening the mould, greatly reduced the cost, and be provided with chamfer portion at the head of thimble body, along with the pushing down of last hot plate, the thimble body can be experienced and contract down, vacate the space for the deformation of aluminum pipe simultaneously, both blocked the pipe, do not extrude the aluminum pipe again, can effectually avoid the aluminum pipe to receive the extrusion and take place to warp.

Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Example 1

As shown in fig. 1-3, a novel plane vulcanizer fixed thimble comprises a sleeve 1, and a lower steel plate 6 and an aluminum pipe which are arranged on the plane vulcanizer, wherein the sleeve 1 is arranged in the lower steel plate 6, a cylindrical cavity is arranged in the sleeve 1, a cylindrical groove is arranged on the sleeve 1, the sectional dimension of the cylindrical groove is smaller than that of the cylindrical cavity, a spring 2 is arranged in the cylindrical cavity, a thimble body 3 is arranged on the upper side of the spring 2, a protruding part 4 is arranged at one end of the side, close to the connection side of the thimble body 3 and the spring 2, of the thimble body 3, and a chamfered part 5 is arranged at the other end of the thimble body 3.

It should be noted that: be equipped with the locating hole 7 that supplies sleeve 1 to pass in the lower steel sheet 6, through having seted up locating hole 7 on lower steel sheet 6 for sleeve 1 can be dismantled and locate in locating hole 7, thereby has saved the step of reopening the mould. The sleeve 1 is provided with a plurality of groups in the lower steel plate 6. The sleeve 1 is uniformly distributed on the outer side of the aluminum pipe, the aluminum pipe can be conveniently positioned by limiting the sleeve 1, and meanwhile, the aluminum pipe is prevented from being extruded and deformed when being flattened and deformed.

As shown in fig. 4, the thimble body 3 is telescopically arranged in the sleeve 1.

The plane vulcanizer is also provided with an upper hot plate, wherein the upper hot plate and the lower steel plate 6 are oppositely arranged.
