Abstract
The present invention belongs to a tire production tooling, specifically relates to a fully folding machine head. The fully folding machine head comprises a main connection rod, a secondary connection rod, a drum rack, an adjustment ring and a drum shoulder. The drum rack is connected with a drum wing. The main connection rod is provided with a positioning assembly, and is connected with a connection rod I by a pin. The secondary connection rod is connected with a connection rod II and a connection rod III by pins. The connection rod I, the connection rod II and the connection rod III are respectively connected with the drum wing by pins. The adjustment ring and the drum shoulder are connected with the drum rack by bolts. Compared to the prior art, the gap is arranged on the position of the circle opening, the folding can be directly performed on the 4th roller pressing tipping forming machine, and then the tire blank can be taken. The fully folding machine head of the present invention adopts the inertia to carry out folding, the margin tile disassembly is not required, the labor intensity can be reduced, and the production efficiency can be improved.
Description
Technical field
The invention belongs to the frock of tire production, be specifically related to a kind of former of producing tire.
Background technology
Space saver tire former is the mould that the important procedure-tyre building in tyre production technology process is used, and is also mounted in the matching die on tyre building machine.The tire of different structure and specification need to adopt head dissimilar, differently contoured curve, can produce the green tyres meeting the requirements.Application number is that the utility model patent that " 02273003.6 ", name are called " 12 watts of formula formers " has been introduced a kind of former, is suitable for the moulding of the tires such as radial.The full foldable nose of existing 23.5-25 as depicted in figs. 1 and 2, comprise master connecting-rod 1, pair connecting rod 8, drum frame 9, adjustable ring 4, drum shoulder 6, connecting rod, positioning component 12 etc., wherein rouse frame circumferencial direction piecemeal (6 ~ 10), adjustable ring 4 is also divided into identical piece number with drum shoulder 6 and couples together by bolt and drum frame 9.Drum shoulder 6 is divided into again two parts at place, outer end, and a part is provided with breach, and another part fastens connected herein, and every limit watt connects by bearing pin guide C.After the moulding of tire base is complete, need to first the limit at A place watt be disassembled, head could be realized folding, and dismounting limit watt-hour need to pull open the handle on B place bearing pin, the first piece watt is laid down, can take out one by one limit watt below, every of used 23.5-25 head limit watt weight is about 15-20Kg, its labour intensity is large, production efficiency is low, and potential safety hazard is larger.
Summary of the invention
The technical problem to be solved in the present invention is that existing 23.5-25 head need to be dismantled limit watt when folding, cause that production efficiency is low, labour intensity is large, a kind of full foldable nose that relies on inertia directly to fold is provided, can enhances productivity, reduce labour intensity.Technical scheme of the present invention realizes in the following manner:
A kind of full foldable nose, comprise master connecting-rod, pair connecting rod, drum frame, adjustable ring and drum shoulder, drum frame is connected with fluttering, master connecting-rod is provided with positioning component, master connecting-rod is connected with connecting rod I by bearing pin, pay connecting rod and be connected with connecting rod III with connecting rod II by bearing pin, connecting rod I, connecting rod II, connecting rod III are connected with fluttering respectively by bearing pin, and adjustable ring is connected with bulging frame by bolt with drum shoulder.
Described bulging frame is 10 ~ 12 of circumferencial direction piecemeals, and drum shoulder is also divided into the piece number identical with drum frame with adjustable ring.
The external diameter of described drum shoulder is 860mm.
Compared with prior art, the present invention is provided with breach at ring edge position, on No. 4 pressure roller edging moulding machines, can directly fold, and then fetus is taken out.The present invention utilizes inertia to fold, and does not need to dismantle limit watt, can reduce labour intensity, enhances productivity.

The specific embodiment
As shown in Fig. 3 ~ 6, the present invention includes master connecting-rod 1, pair connecting rod 8, drum frame 9, adjustable ring 4 and drum shoulder 6, master connecting-rod 1 is provided with positioning component 12, master connecting-rod 1 is connected with connecting rod I 2 by bearing pin, paying connecting rod 8 is connected with connecting rod III 7 with connecting rod II 3 by bearing pin, connecting rod I 2, connecting rod II 3, connecting rod III 7 by bearing pin respectively be welded on fluttering on bulging frame and 5 be connected, adjustable ring 4 is connected with drum frame 9 by bolt with drum shoulder 6.
Described bulging frame 9 is 10 ~ 12 of circumferencial direction piecemeals, and drum shoulder 6 and adjustable ring 4 are also divided into the piece number identical with drum frame 9.
The external diameter of described drum shoulder 6 is 860mm.
Described adjustable ring 4 is provided with groove 4-1, and drum frame 9 is provided with protruding 9-1, and protruding 9-1 is arranged in groove 4-1.
The course of work of the present invention is as follows: master connecting-rod 1 is connected with the main shaft 11 of forming machine by key, and the brake cover of forming machine main spindle 11 outsides is connected by spline with a pair connecting rod 8.When head folds, need first the pin that draws of a side in positioning component 12 to be pulled out from drawing in key seat, forming machine main spindle 11 reversions, ringfeder in brake cover is opened brake cover is stopped, because brake cover is paid connecting rod 8 with head and is connected, the connecting rod 8 of paying of head stops, forming machine main spindle 11 is rotated further, drive head master connecting-rod 1 to rotate, the master connecting-rod 1 of head, pair connecting rod 8 produce relative motions like this, by inertia, the plunger in the positioning component 12 in head is ejected, driven connecting rod I 2, connecting rod II 3, connecting rod III 7 also to produce relative motion simultaneously.Connecting rod drive 10 or 12 pieces watts together motion head is folded up.Same reason, makes it return to the state originally opening during forming machine forward, the plunger in positioning component 12 also returns to original position.
