Description

Spiral type shaping vulcanizer

The present invention relates to the rubber manufacturing machinery of rubber tyre first cure.

Present sulfurizing rubber tyre machine is to be modified into balance-type type hydraulic pressure shaper vulcanizer by the fifties crank-linkage type tire forming vulcanizer to the seventies, replace toggle with hydraulic cylinder, make designs simplification, weight reduces 1/3rd, but because of hydraulic part does not pass a test, be difficult to guarantee product quality, the eighties state is extrapolated last cylinder type hydraulic shaper vulcanizer, satisfy the required precision of radial to equipment, but because of the equipment price costliness, the consumable accessory of hydraulic system is too many, the maintenance difficulty, structure is still complicated, and floor space is still bigger than normal.

The purpose of this invention is to provide a kind of spiral type shaping vulcanizer, make designs simplification, compactness, floor space is little, and equipment cost is low, and the precision height is easy to care and maintenance, and can work by many vulcanizer continuous-flow types, improves work efficiency.

Purpose of the present invention realizes by following measure, equipment component at original vulcanizer, base 1, central authority 2, on the basis of tire-mold, re-use existing parts motor and transmission device 18, bearing etc., vulcanizer is improved, and feature is main stand is fixed in base 1 by left and right door bolt key 3,41 down and screw 4,40 by the below of left and right side plate 13,29 a and arranged on left and right sides; The top is by a left side, upper right door bolt key 15,27 and screw 16,26 with entablature 17 formation that is connected, motor and transmission device 18 are fixed on the top of entablature 17, aperture flat key 19 and transmission nut 22 close-fittings within the worm gear 21 of this transmission device, transmission nut is by bearing 25,31 through bearing block 28, gland 32 is fixed in the middle part of entablature by screw, in the bearing block of bearing 25 tops load sensor 24 is housed, spiral 23 and transmission nut 22 engagements, and match by the guiding feather key 33 at gland endoporus place and two axial long keyway on the spiral, make on the spiral, under play the guide-localization effect when moving, spiral lower end is hemisphere 14 and links to each other with half module 8 on the spiral shell loose tool tool, guarantee that the pressure behind the matched moulds is even, female die 5 is fixed in the top of base 1, the side is a central authority 2 under the female die center, a left side, right plate 13,29 installed inside has guide rail 10,27, two slide blocks 7 about upper mold section 8,34 on a left side, form sliding pair in the right guide rail, guarantee upper mold section and female die mold alignment.

Worm gear 21 also can be processed as the overall structure of nut by the worm gear endoporus by the version of flat key 19 with transmission nut 22 close-fittings.

Left and right, upper and lower door bolt key 15,2,27,41 also available pins substitute, and perhaps each connector with the junction is welded in one.

By base 1, left and right side plate 13,29, the main stand that entablature 17 constitutes also can substitute with single-casting.

Load sensor 24 also can be installed in the relevant position that transmits clamp force, perhaps is affixed on place, the outer garden of spiral with foil gauge and substitutes.

This vulcanizer is the building block system cellular construction of separate unit mould, can two vulcanizers be combined into bimodulus according to the needs of producing, and can be combined to pick up platform, 20 multimode spiral type shaping vulcanizer, to improve the production work efficiency always.

Advantage of the present invention is the top that motor and transmission device are installed in complete machine, makes compact conformation, and floor space is little, the pressure that mold clamping force adopts screw pair to produce, make designs simplification, precision improves, and equipment cost reduces, and maintenance for ease of maintenaince, and can many combinations, enhance productivity.

Description of drawings is as follows:

Fig. 1 is the structural representation of spiral type shaping vulcanizer.

Fig. 2 is two mould spiral type shaping vulcanizer combination schematic diagrames.

The present invention's prize is further described in conjunction with the accompanying drawings, and shown position is the sulfided state of tire, after sulfuration is finished, machine operation, worm gear 21 rotates, and transmission nut 22 rotates, spiral 23 moves upward and drives upper mold section 8 along moving on the guide rail, and by spacing near switch, motor quits work, the water vat of central authority 2 below enters press water simultaneously, moves on the piston rod, and central authority is up, capsule is peeled off from tire, take out tire, central authority resets, this next tire base of packing into constantly, machine operation, the worm gear backward rotation, the transmission nut backward rotation, spiral is descending, upper mold section moves down along guide rail, carry out tire base typing, matched moulds then is when the clamp force behind the matched moulds reaches load sensor 24 predefined pressure, locking, motor quits work, mold heated sulfuration, so circulation.Be to improve work efficiency, can adopt two or many vulcanizers to work simultaneously, this vulcanizer more behind mold exchange and the associated components, is equally applicable to the tyre capsule vulcanizer, tyre retreading vulcanizer, various vulcanizing presses etc.
