Lock ring type tyre hydraulic vulcanizing machine

Abstract

The invention provides a lock ring type tyre hydraulic vulcanizing machine. The top of an upper lock ring base is fixed to an upper supporting plate. A lower base plate is fixed to a base. The lock ring is arranged on the lower base plate. The lock ring and the upper lock ring base are provided with matched lock teeth. A mould locking cylinder is fixed to the base, and a piston rod of the mould locking cylinder is connected with the lock ring. A stress application cylinder is fixed to the lower base plate, and the piston rod of the stress application cylinder passes through the lower base plate and then is fixedly connected with the lower supporting plate. The stroke of the stress application cylinder is greater than or equal to the sum of the maximal adjustment mould stroke and the stress application stroke. Two opening and closing mould cylinders are at a diagonal position of the upper lock ring base and are fixedly connected with the base. The tops of the opening and closing mould cylinders are connected with the upper lock ring base. Two guide columns pass through a guide sleeve of the upper lock ring base, the bottoms of the two guide columns are fixedly arranged at the base, and the top ends of the two guide columns are fixedly connected with a top frame. The opening and closing mould cylinders drive an upper mould to vertically lift under the guide of the guide columns when the mould is opened and closed. The lock mould cylinder pushes the lock ring to rotate to loosen and lock the lock mould. The vulcanizing machine is uniform in bearing, safe and reliable. The stress application cylinder pushes a lower supporting plate to lift. The stroke of the stress application cylinder realizes automatically stepless mould adjustment and stress application, and simplifies the structure.

Description

(1) Technical field [0001] The invention relates to rubber tire vulcanization equipment, in particular to a locking ring type tire hydraulic vulcanization machine. (2) Background technology [0002] Existing hydraulic vulcanizers for tires all have a frame structure, and the movement of the crossbeam is a single vertical lift. The hydraulic system drives the piston rod of the mold opening and closing cylinder to reciprocate up and down, and drives the upper heating plate, upper supporting plate and upper mold installed on the beam to lift up and down to realize mold opening and closing. At the same time, in order to ensure that the lifting movement of the upper mold is vertical, guide rails are provided on both sides of the frame. Existing tire vulcanizers are composed of left and right racks, crossbeams, bases, left and right vulcanization chambers, and central mechanisms, making the left, right, and upper and lower spaces of the vulcanizer relatively narrow, which is not ...

AI Technical Summary

Problems solved by technology

Existing tire vulcanizers are composed of left and right racks, crossbeams, bases, left and right vulcanization chambers, and central mechanisms, making the left, right, and upper and lower spaces of the vulcanizer relatively narrow, which is not conducive to the installation and maintenance of the vulcanizer, and is also not conducive to Pipeline optimization design, pipeline installation and maintenance

Not only the installation and use of the whole machine takes up a lot of space, but also the accuracy is difficult to guarantee

On the other hand, due to the complex structure of the existing hydraulic vulcanizers, the processing cycle is long, the cost is high, and the quality control is also relatively difficult.
