Abstract
A movable end cap of a vulcanization core rod comprises a cap body, a length adjusting block and an angle adjusting block; the cap body is a hollow cylinder, one end of the cap body is provided with a length adjusting block and an angle adjusting block, and a guide block and a guide groove are arranged between the cap body and the length adjusting block and are positioned and connected through a positioning hole; the cap main body, the length adjusting block and the angle adjusting block are coaxially connected. The utility model discloses a cap main part, length adjustment piece, angle adjusting block's design makes the maintenance number of times of plug reduce, makes the plug adjustment become simple swift, strengthens the stability of plug to guarantee product quality's uniformity.
Description
Technical Field
The utility model relates to a heterotypic rubber tube vulcanizes design technical field, mainly relates to the plug that car turbocharging pipeline, vehicle air conditioner water pipe made and use.
Background
The special rubber pipe is made up by using a kind of tubular rubber product for conveying gas, liquid, slurry and granular material, extruding out inner and outer layer rubber by means of extrusion equipment and adding rubber pipe skeleton layer by means of braiding equipment. The shaping of the special-shaped rubber tube mainly adopts a core rod to vulcanize and shape, the core rod is sleeved on an unvulcanized rubber tube, the length of the rubber tube is limited and an assembly marking is extruded through a fixed end cap and a movable end cap, then the rubber tube is sent into a vulcanizing tank to carry out steam vulcanization and shaping, the rubber tube after vulcanization is in accordance with the length requirement of a product checking fixture and the trend of a cavity of the checking fixture, the interference problem cannot be caused, and the position of the assembly marking is in accordance with the checking fixture.
In order to meet the length requirement of a product, enough allowance is left at the end part of a vulcanized rubber pipe, and the redundant rubber pipes at two ends are cut off according to the size requirement after the vulcanization is finished in the conventional process; in order to avoid assembly position errors, a positioning mark is usually required to be added on the outer surface of the rubber tube, and the existing process generally comprises the steps of printing the mark through a product profiling tool and punching a hole through a punching machine after vulcanization.
The method for ensuring the size and the assembly position through the cutting, printing and punching processes after the vulcanization is finished increases the production processes, increases unnecessary production equipment, workers and scrapping of raw materials, has long production period, and increases the production cost of the product!
Chinese patent CN209492162 discloses a vacuum-pumping core rod device, which mainly solves the problem of rubber tube vulcanization bulge by vacuum pumping.
Chinese patent CN201721199334 discloses an end cap tool for a core rod, which mainly adjusts the length and angle of a core rod cap by bolts to ensure that the length and assembly mark line of a rubber tube meet the product requirements.
The above-mentioned published chinese patent theoretically solves the problem of uniform fixation of the length of the rubber tube and the positioning mark, but in actual production, in the continuous operation process of the mandrel, the screw is easy to loosen, which causes the product to be bad, and when adjusting the mandrel, the adjusting bolt moves in both axial and radial directions, which is not easy to adjust, thereby causing the length of the rubber tube to be different and the positioning mark line to be deviated.
Disclosure of Invention
To the problem, the utility model aims to provide a be fit for the adjustment of dysmorphism rubber tube plug, make the plug after vulcanizing the design satisfy length requirement and location sign requirement, reduce the stability of adjustment plug time and improvement plug, guarantee the plug cap of the quality of heterotypic rubber tube.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a vulcanize plug cap, includes cap main part, cap regulating block, plug cap main part be the cylinder, cap tip division horn mouth, cap embedding mark block, cap platform face are equipped with the unequal air vent of 12-24, the guide block is done to the afterbody.
The cap regulating block is a cylinder, the regulating block is divided into a length regulating block and an angle regulating block, a guide groove is arranged in the length regulating block, a positioning threaded hole is formed in the outer part of the length regulating block, the angle regulating block is provided with 3 arc grooves which are connected with the length regulating block in a positioning mode through bolts, and a positioning locking hole is formed in the middle of the angle regulating block. The cap adjusting block is coaxially connected with the cap main body, and the length of the cap main body is larger than that of the cap adjusting block.
The utility model has the advantages that:
1. the utility model discloses simple structure adopts cap main part and cap regulating block cooperation, makes the cap difficult not hard up, adjusts easily, vulcanizes back rubber tube size stability, and the rejection rate reduces, reduces plug adjustment number of times and time, has improved production efficiency, practices thrift the cost.
2. The utility model discloses an adopt the mode of cap regulating block components of a whole that can function independently regulation cap length and angle, influence the cap angle when having avoided regulation cap length, or influence the problem of cap length when adjusting the cap angle. The cap adjusting process is simplified, the acceptance efficiency of the core rod is improved, the maintenance frequency of the core rod is reduced, and the product scrap is reduced.
