Description

Winding tool for manufacturing plastic liner carbon fiber full-winding high-pressure hydrogen storage cylinder

Technical Field

The utility model relates to a tool, in particular to a winding tool for manufacturing a plastic liner carbon fiber full-winding high-pressure hydrogen storage cylinder, and belongs to the technical field of mechanical structure transformation.

Background

Along with the rapid development of the hydrogen energy industry, the application of the high-pressure hydrogen storage pressure container is wider and wider, the product weight reduction is more and more important in the field of automobiles, and the technical development of the hydrogen storage composite material gas cylinder of the plastic liner is faster and faster. Because the strength of the plastic material is weaker, the requirement of high-pressure gas storage cannot be met. The compressive strength of the container is improved by a carbon fiber winding process on the plastic liner, and the hydrogen storage bottle which is in line with the application of the hydrogen energy industry is formed.

At present, when the plastic inner container is wound, air needs to be filled into the inner cavity of the plastic inner container for many times before and during winding, so that the inner cavity is wound under the state of keeping rated expansion pressure. In the large-scale machines of current winding operation, the assembly of frock and inflation and release gas that is used for plastics inner bag to carry out horizontal attitude clamp fixed is the monomer design, can only realize outside inflation, has not only reduced the production efficiency of product, can't monitor the product internal pressure in winding and solidification in-process moreover, influences product quality.

Disclosure of Invention

The utility model aims to provide a winding tool for manufacturing a plastic liner carbon fiber full-winding high-pressure hydrogen storage cylinder, and solves the problem of integration of the winding tool and inflation of the plastic liner.

The technical scheme of the utility model for realizing the purpose is that a winding tool for manufacturing the high-pressure hydrogen storage cylinder by fully winding carbon fiber of the plastic inner container is arranged on a rack of a winding machine and is opposite to one end of the plastic inner container to be connected.

Above-mentioned winding frock, further, the inside diameter of sleeve mouth and the external diameter of bellying satisfy the sleeve mouth and go out and overlap in the bellying with the cooperation.

Above-mentioned winding frock, still further, the bellying has cup jointed more than one Y type sealing washer.

Above-mentioned winding frock, further, the butt joint is equipped with external screw thread and spacing bulge loop that matches with the plastics inner container bottle mouth and meet.

Above-mentioned winding frock, further, winding frock is equipped with the keyway in the surface that self main part is close to sleeve mouth department, and cup joints fixed a set of rotatory sprocket through the key pin.

By using the winding tool with the improved structure, the utility model has the advantages that the traditional tool is hollow and improved and the miniature one-way valve is integrated, the plastic liner can be automatically inflated by matching with the winding process, meanwhile, the inflation and deflation pipelines of the curing furnace are connected to realize the internal pressure monitoring of the curing process, and the production process requirements of two stages of winding and curing can be met.

Description of the embodiments

The following detailed description of the embodiments of the present utility model is provided with reference to the accompanying drawings, so that the technical scheme of the present utility model is easier to understand and grasp, and the protection scope of the present utility model is defined more clearly.

The utility model provides a special winding tool for manufacturing to be matched with the plastic liner for inflation, aiming at a plurality of defects of the prior process for fully winding carbon fiber in the production of the hydrogen storage cylinder plastic liner and exposure.

From the technical outline, the winding tool 3 for manufacturing the plastic liner carbon fiber full-winding high-pressure hydrogen storage cylinder is arranged on the frame 2 of the winding machine and is opposite to one end of the plastic liner 1 to be connected. The structure improvement is that the winding tool 3 is a hollow shaft tube, one end of the main body of the winding tool is provided with a butt joint 31 corresponding to the bottleneck of the plastic liner, and the other end is provided with a sleeve opening 32 of the butt joint rack bulge 21. The bottom of the sinking tank of the sleeve opening 32 is integrally connected with a miniature one-way valve 4, the air inlet end of the miniature one-way valve 4 is externally connected with an air source 6 at the sleeve opening, and the air outlet end of the miniature one-way valve is communicated with the clamped plastic liner 1 through an inner cavity 33 of the shaft tube. The convex part of the frame is also axially hollow, so that the connectivity between the air inlet end of the one-way valve and an air source is met.

From the aspect of further refinement, the abutment 31 is provided with an external thread 311 and a limiting convex ring 312 which are matched and connected with the mouth of the plastic inner container. Therefore, the bottleneck of the plastic liner can be sleeved on the pair of connectors and screwed on the limiting convex ring, so that firm assembly is realized. From the other side, the inner diameter d1 of the sleeve opening 32 and the outer diameter of the protruding portion 21 are sleeved on the protruding portion in a manner of meeting the condition that the sleeve opening is excessively fit, and one or more Y-shaped sealing rings 22 (two in the illustrated embodiment) are optionally sleeved on the protruding portion 21 so as to prevent leakage of high inflation pressure in the plastic liner and keep the internal pressure stable.

Furthermore, the winding tool 3 is provided with a key slot 34 (as partially shown in another view on the upper side of fig. 2) on the surface of the main body near the sleeve opening, and a set of rotary sprockets 5 can be sleeved and fixed at the position by using a key pin (not shown). Therefore, under the drive of the rotary chain wheel, the winding tool can drive the clamped plastic liner to rotate, and the plastic liner uniformly rotates in the curing process after winding is completed, so that the condition that the curing uniformity is damaged is avoided.

The application of the winding tool is that the plastic inner container is tightly assembled with the plastic inner container, and before and during the winding process, the plastic inner container is filled with gas according to the requirement through the miniature one-way valve, so that the inner container performs the winding operation under the state of keeping the pressure. Without increasing the complexity of the winding machine peripheral.

In summary, the present utility model winding tool is described in conjunction with the illustrated scheme and the detailed embodiments, and the scheme has substantial characteristics and improvements: through carrying out cavity improvement and integrated miniature check valve to traditional frock, can cooperate winding technology to carry out automatic inflation to the plastics inner bag, the internal pressure control to the solidification process is realized to the gassing pipeline of connecting the curing oven simultaneously, can satisfy the production technology requirement of winding and solidification two stages.

In addition to the above embodiments, other embodiments of the present utility model are possible, and all technical solutions formed by equivalent substitution or equivalent transformation are within the scope of the present utility model as claimed.
