Abstract

The utility model discloses a plastic tubepipe-expanding machine which consists of a heating device and a forming traction device. The heating body of the heating device is a heating cover, a heating ring and a heating lining from outside to inside. An eccentric wheel of the traction device is connected with one end of a connecting rod through a rolling pin shaft and the other end of the connecting rod is connected with a slide cover which is sliding fit for a guiding rod. The slide cover and a clamp ring are fixed on a supporting board. The guiding rod and a bearing holder fixed on a frame are permanent fit. The utility model has the advantages of reasonable structure, low cost, easy operation, convenient maintenance and low energy consuming.

Description

The plastic pipe pipe-expanding machine

The utility model relates to a kind of plastic pipe pipe-expanding machine, belongs to be convenient to a kind of special plastic plant equipment that the two tubes straight line connects.

Existing pipe-expanding machine mainly by draw-gear, move materials device heating reaming bedstead, heating whirligig, heating cabinet, reaming gripping mechanism, reaming case etc. automatically and form.Be characterized in that tubing adds the inside and outside hot blast mode of heating of thermal recovery, and be provided with the forward and reverse whirligig of tubing, heating cabinet is provided with the cold water circulation simultaneously, high pressure typing and air cooling equipment are joined by forming room.After carriage was sent the plastic tube flared part into the baker thermoplastic, the Molded Depth that rises was gone into the tubing end, and the upper and lower mould closure is after the pipe that rises is shaped, by hydraulic traction device holder mould.This pipe-expanding machine adopts the Hydraulic Elements device more, and mechanism is comparatively complicated, bulky, higher to operator's specification requirement, and energy resource consumption is bigger, the maintenance of equipment difficulty, move inconvenience, the department that should not need often to change the processing place uses, and higher to water, electric equal energy source conditional request.

The purpose of this utility model be to overcome the weak point in the background technology and provide a kind of simple in structure, cost is low, easy operating, is convenient to the plastic pipe pipe-expanding machine of safeguarding, consume energy low.

The utility model be achieved in that it comprise the heater formed by calandria, trustship roller, hoistable platform and by the enlarging internal mold, step up to encircle, moulding draw-gear that header tank, haulage gear are formed, its calandria is made up of heating jacket, heating collar, heating liner, is followed successively by heating jacket, heating collar, heating liner from outside to inside; The eccentric wheel of haulage gear links to each other with connecting rod one end by rotating pin, the connecting rod other end links to each other with sliding sleeve by rotating pin, and sliding sleeve and guide post are slidingly matched, and sliding sleeve is fixed on the gripper shoe, clamping ring is fixed on the gripper shoe, guide post and the supporting seat stationary fit that is fixed on the frame.

The utility model compared with prior art has following advantage:

1, forms by calandria, trustship roller, hoistable platform owing to heater, calandria is followed successively by heating jacket, heating collar, heating liner from outside to inside, the haulage gear of moulding draw-gear is cooperated the traction of finishing profiled member by connections such as eccentric wheel, connecting rod, sliding sleeve, guide posts, therefore complete machine structure is simple, easy operating is convenient to safeguard;

2, because the heating collar of calandria is in the position, middle level, the heating jacket protection is arranged outward, reduce thermal loss, in establish the heating liner, make homogeneous heating, and remain on suitable temperature, energy resource consumption is low;

3, simple in structure, volume is less, and heater and the split of moulding draw-gear are convenient to running is installed, and suit especially to use at the plastic pipe mounting site, and easy and simple to handle, the workman easily grasps;

4, cost is low.

Description of drawings:

Accompanying drawing is the utility model structural representation

Among the figure: location-plate 1, enlarging internal mold 2, header tank 3, frame 4, clamping ring 5, gripper shoe 6, sliding sleeve 7, connecting rod 8, rotating pin 9, eccentric wheel 10, heating jacket 11, heating collar 12, heating liner 13, frame 14, trustship roller 15, hoistable platform 16, lifting screw 17, motor 18, supporting seat 19, guide post 20.

Below in conjunction with drawings and Examples in detail the utility model is described in detail: as shown in the figure, heater is by calandria, trustship roller 15, hoistable platform 16, frame 14 is formed, hoistable platform 16 places frame 14 tops, its both sides are provided with lifting screw 17, be used to regulate the height (lifting) of hoistable platform 16, trustship roller 15 is fixed on the hoistable platform 16, calandria places on the frame of trustship roller 15 front ends, by heating jacket 11, heating collar 12, heating liner 13 is formed, be followed successively by heating jacket 11 from outside to inside, heating collar 12, heating liner 13, heating collar 12 is to be made of mica sheet, promptly implements heating after the energising, will be placed in the calandria by plastic tube one end of enlarging during work.The moulding draw-gear is by enlarging internal mold 2, clamping ring 5, header tank 3, compositions such as haulage gear, enlarging internal mold 2 is fixed on the frame 4 by location-plate 1, enlarging internal mold 2 belows are provided with header tank 3, the eccentric wheel 10 of haulage gear is connected with connecting rod 8 one ends by rotating pin 9, connecting rod 8 other ends link to each other with sliding sleeve 7 by rotating pin, sliding sleeve 7 is slidingly matched with guide post 20, sliding sleeve 7 is fixed on the gripper shoe 6, clamping ring 5 is fixed on the gripper shoe 6, guide post 20 and supporting base 19 stationary fits that are fixed on the frame, motor 18 links to each other with eccentric wheel 10 by reductor.During work, the fire end 12 of plastic pipe is sleeved on the plastics mouth of pipe on the enlarging internal mold 2 with the cooling of cold water spray, enter header tank 3 with the water of crossing, clamping ring 5 clamps the processed plastic pipe other end, by moving behind motor 18 drive eccentric wheels 10, connecting rod 8, guide post 20 and the clamping ring 5, work piece is taken off from enlarging internal mold 2 finish enlarging.
