Abstract

The invention relates to a mechanical shaping method for automobile tire vulcanization molding. By using the rigid supporting effect of a mechanical shaping device to replace the flexible supporting effect of a capsule or a molding bag, insufficient tire dynamic balance accuracy caused by uneven wall thickness of the capsule or the molding bag is made up; by using the radial expansion or contraction of the mechanical shaping device to replace the expansion or contraction of the capsule or the molding bag, the goal of smoothly stripping off the tire is achieved; and by using steel materials to replace the rubber materials of the capsule or the molding bag, the goal of prolonging the service life is achieved. The mechanical shaping method comprises the working steps that: the mechanical shaping device is connected with the lower tray of a vulcanizing machine in advance and is kept in a contracted state; a segmented mold is installed on the vulcanizing machine and necessary preheating is conducted according to requirements on preheating before normal vulcanization; the vulcanizing machine starts to act, the detachable mold is opened and a green tire is installed; the vulcanizing machine acts, a slideable connecting rod seat on the mechanical shaping device is pushed, large shoes and small shoes are expanded to form an entire circle to shape the inner wall of the green tire; the vulcanizing machine continuously acts to drive the segmented mold to be closed and vulcanize; and the segmented mold is opened after vulcanization is finished and the tire is held and sent away by a manipulator.

Description

A kind of mechanical method for shaping of vehicle tire sulfuration moulding

Technical field

The present invention relates to a kind of mechanical method for shaping of vehicle tire sulfuration moulding.

Background technology

At present, tire vulcanization process both domestic and external is to adopt capsule or curing bag without exception, and one of its major reason is exactly that capsule or curing bag can fill vapour and expand and be adjacent to the green tyre inwall, and compression tire base is so that tyre setting.

Adopting capsule or curing bag to carry out the first cure tire is a kind of traditional technique, yet, because the service condition of tire curing bladder is very harsh, the capsule serviceability temperature is generally the 180-200 degree.The medium of contact is mainly superheated water, superheated steam, compressed air or nitrogen.The very large especially capsule of oblique type of capsule extension ratio.Capsule or curing bag often under high-pressure high-temperature environment ceaselessly dilation alternately, so be difficult to maintain its service life for a long time, average is approximately 500 times service life.Once there are quality problems in the capsule or the curing bag that use, also may occur breaking and cause tire to scrap, security incident even occurs.Adopt capsule or curing bag to come the first cure tire also to have a kind of hidden danger of quality, if there is became uneven in the wall thickness of capsule or curing bag exactly, when it fills the shape expanded after superheated water or nitrogen, not uniform so, finally cause the tire wall thickness not reach designing requirement, thereby affect the dynamic balancing of tire.

Summary of the invention

The object of the invention is to overcome existing capsule or the shortcoming of curing bag in vehicle tire sulfuration moulding type-approval process, a kind of mechanical method for shaping of vehicle tire sulfuration moulding is provided.

The present invention, utilize mechanical shaping equipment to replace capsule or curing bag, green tyre inwall typing for the tyre vulcanization forming process, utilize the supporting role of the mechanical rigid of mechanical shaping equipment to replace the flexible support of capsule or curing bag, utilize the action of radially opening or shrinking of mechanical shaping equipment to replace expansion or the contraction of capsule or curing bag, described mechanical shaping equipment comprises that the sheet number equates and little watt of drum with each other watt and large watt of drum watt mutually, and be arranged at slide link seat and the hold-down support on the vulcanizer connecting bushing, every little watt of drum watt little watt bulging piece corresponding with it is fixedly connected with, every little watt bulging piece is by a pair of, under the little watt of long connecting rod and the slide link seat that be arranged in parallel be articulated and connected, the middle part of little watt of long connecting rod on every, a little watt of short connecting rod is articulated and connected, the other end of little watt of short connecting rod, with hold-down support, be articulated and connected, every large watt of drum watt large watt bulging piece corresponding with it is fixedly connected with, every large watt bulging piece is articulated and connected by a pair of upper and lower large watt of long connecting rod be arranged in parallel and slide link seat, the centre of large watt of long connecting rod on every, a large watt of short connecting rod is articulated and connected, the other end of large watt of short connecting rod, with hold-down support, be articulated and connected, hold-down support is fixedly connected with the vulcanizer connecting bushing by bearing pin, on the vulcanizer connecting bushing, be provided with slide link seat spacing ring.

The present invention, its job step comprises:

A, described mechanical shaping equipment is connected with the lower tray of vulcanizer in advance, and in contraction state;

B, activating mold is loaded onto to vulcanizer, by preheating requirement before normal sulfuration, complete necessary preheating;

C, vulcanizer start action, open activating mold, load onto the tire base;

D, vulcanizer action, promote the slide link seat on mechanical shaping equipment, makes large watt of drum watt open and form full circle with little watt of drum watt, and tire base inwall is finalized the design;

E, vulcanizer continue action, order about activating mold and carry out matched moulds sulfuration;

F, vulcanized the after cure machine start the action, order about activating mold and open and rise to certain altitude;

G, then vulcanizer orders about mechanical shaping equipment and rises to a safe altitude with whole tire;

H, mechanical arm of vulcanizer are held tire, and mechanical shaping equipment starts to shrink under the ordering about of vulcanizer until, in complete contraction state, by the tire disengaging of sulfidization molding, tire is directly caught and seen off by mechanical arm of vulcanizer, completes whole sulfidation.

The present invention has following good effect: 1, utilize the supporting role of the device rigidity of mechanical first cure automobile tire to replace the flexible support of capsule or curing bag, made up the tire dynamic and balance precision deficiency caused because of capsule or curing bag wall unevenness; 2, utilize the action that the device of mechanical first cure automobile tire radially opens or shrinks to replace capsule or curing bag expand or shrink, reach the purpose that meets smooth tread flaking; 3, utilize steel material to replace the quality of rubber materials of capsule or curing bag, reach the purpose that improves service life; 4, utilize the low cost of the device of mechanical first cure automobile tire to replace the expensive of capsule or curing bag, simultaneously because utilize the device of mechanical first cure automobile tire to replace capsule or curing bag, superheated water or nitrogen that heat and pressure are provided to capsule or curing bag have been reduced, also have, can relevant pipeline and the device of corresponding minimizing on vulcanizing equipment, saved a large amount of energy and material and equipment cost, made tire producer really reach cost-saving purpose; 5, adopt the device of mechanical first cure automobile tire to replace traditional tyre vulcanization mode can avoid filling superheated water or nitrogen because of capsule or curing bag, grown aging service time, and constantly dilation also can cause fatigue and break, and finally causes producing even security incident of damaged tire; 6, adopt the device of mechanical first cure automobile tire to replace traditional tyre vulcanization mode disposablely to install, avoid traditional capsule or curing bag of adopting to need constantly to change and the phenomenon of shutdown, save time, enhance productivity.
