Abstract

The present invention is the improvement to free style non-reinforced concrete tuber, it is characterized in that having designed the pressure pressing mechanism of forming by two pairs of hold-down roll, automatic infiltration mechanism that forms by swivel joint etc. and the passive running roller of taper type on the bistrique, constant voltage and inwall to pipe when having realized spinning seep water, made water-supply-pipe is longer, thinner, and the degree of packing and barrier performance obviously improve.

Description

Concrete pipe-manufacturing machine

The invention belongs to the machinery of producing the tubular water mud product, particularly a kind of concrete pipe-manufacturing machine of producing no-reinforcing-bar thin-walled water-supply-pipe.

No muscle thin wall concrete water-supply-pipe is as irrigation and water conservancy antiseepage pipeline.Have with low cost, the high obvious advantage of emptying effectiveness.This water pipe generally with upright extruding process, is produced with the free style tuber at present.

This free style tuber is made up of frame, extruding assembly, mould upper end location-plate, station rotating disk, transmission device and operating mechanism.Wherein pushing assembly is the critical piece of full machine, comprises vertical shaft, drive socket and rotation bistrique.Rotation bistrique top outer rim has two spirality binder pin.Its tubulation process is, the tubulation external mold is placed on the station rotating disk, presses mould upper end location-plate, the drive socket that pushes assembly and bistrique are put into external mold at the bottom of.Constantly add the concrete slurry that mixes and stirs again between bistrique and external mold, drive the bistrique rotation simultaneously, promptly be extruded into pipe between bistrique outer rim and external mold inwall, along with the formation gradually of pipe, bistrique is freely risen by pushing tow, makes up to pipe.Mention die head then, the rotation station rotating disk shifts out pipe die, again pipe die and pipe is moved to the maintenance place, takes external mold away, with the pipe natural curing water-supply-pipe that got product in several days.The extruding force of this free spinning is limited, and unstable, and the pipe degree of packing of making is relatively poor, rough surface, and tube wall is thicker, and its barrier performance, production efficiency and cost are all not satisfactory.

It is thinner to the purpose of this invention is to provide a kind of production tube wall, and pipe shaft is long, cost is lower, and barrier performance is apparently higher than the tuber of existing non-reinforced concrete water-supply-pipe.

Task of the present invention realizes with following technological approaches: on the basis of existing free style tuber, and 1, designed by two pair rollers and transmission, control device and has formed, the clamping square vertical shaft moves up and down, to the pressure voltage stabilizing mechanism of bistrique with specified downforce; 2, designed the tank of crossing on hollow vertical shaft, swivel joint, water valve and the bistrique.In crowded pipe process, to seep water automatically to the pipe inwall; 3, on bistrique, set up a pair of passive extruding running roller.The no muscle thin-walled water-supply-pipe that the pressure spinning tuber of making as the embodiment of above improvement project is produced, compare with existing product, pipe range is lengthened to 1 meter 5 by 1 meter, tube wall is kept to 20 millimeters by 30 millimeters, the consumption of concrete slurry reduces about 30 percent, it is about 30 percent that production efficiency improves, and the degree of packing and the barrier performance of water-supply-pipe obviously improve.

Embodiment further describes the present invention below in conjunction with accompanying drawing:

Fig. 1 is that the embodiment of the invention is forced spinning tuber schematic diagram;

Fig. 2 is the pressure spinning machine schematic diagram of tuber;

As shown in Figure 1, rotating station rotating disk 1 is arranged at the bottom of tubulation frame 23.Open-close type tubulation external mold 2 is placed on the station rotating disk 1, and mould upper end location-plate 6 is pressed on the tubulation external mold 2.From location-plate 6, can in pipe die, dose the concrete slurry.The rotation bistrique 3 of extruding assembly 7 lower ends is driven by hollow main shaft 22, can move up and down in external mold.Extruding assembly 7 and rotation bistrique 2 are driven by motor 8.The hollow vertical shaft 22 of extruding assembly 7 and the upper end of drive socket 8 are connected to swivel joint 18 and square shaft bar 14.In the square shaft bar 14 limbers is arranged, the water that water tank is 12 li flows to square shaft bar 14 by water pipe 13, crosses the annular that water pipe 10 flow to rotation bistrique 2 and cross on the water jacket in swivel joint 18 and hollow vertical shaft 22, when the spinning tubulation, wetting pipe inwall is reduced friction, and improves forming quality.Cross the water valve 10 that has on the water pipe 10 by limit cam 19 controls.When bistrique 3 dropped to external mold 2 bottoms and begins spinning, water valve 10 was opened water supply.Bistrique 3 rises to setting height, and limit cam 19 promotes plunger 20, and valve-off 10 stops to supply water.

As shown in Figure 1 and Figure 2, square shaft bar 14 is by upper and lower the moving of action bars 16,17 controls of forcing spinning machine 15.Force spinning machine 15 by a pair of pressure roller 31, a pair of hold-down roll 25 and relevant parts are formed.The equal clamping square shaft of two pair rollers is 14, and pressure roller 31 is by motor 32, and decelerator 33 and drive 29 drive, square shaft is at the uniform velocity risen 14 with setting speed, thereby bistrique 3 is risen while rotating, and keep a constant downforce, realize forcing spinning.Hold-down roll 25 is by brake ribbon 30 and do bar 17 controls.The clutch of pressure roller 31 is formed in action bars 16, cam 28, clamping plate 27 and extension spring 26.Be used action bars 16 and 17, can make square shaft 14 and bistrique 3 be suspended at arbitrary height or steadily fall.

In order to delay the too early wearing and tearing of two binder pin 4 on the bistrique 3, two passive running rollers of taper type are installed between two presser feets 4, its installation site is lower than the binder pin slightly.When adding slurry like this, cloth is more even, makes pipe very closely knit.

Claims (2)

1, a kind of by frame be installed in the extruding assembly of upper rack and the station rotating disk of frame lower, mould upper end location-plate and transmission device, the concrete pipe-manufacturing machine that operating mechanism is formed, extruding assembly wherein comprises the critical pieces such as rotation bistrique, vertical shaft and drive socket of band binder pin, it is characterized in that:

Termination one swivel joint and square shaft bar on the vertical shaft of a, said extruding assembly, the square shaft bar is equipped with brake ribbon by a pair of hold-down roll and a pair of pressure roller clamping on the hold-down roll, and pressure roller is driven by motor, decelerator and drive;

B, said vertical shaft are the hollow vertical shafts, have annular to cross tank on the said rotation bistrique, and a water pipe is crossed tank with the annular on square shaft bar, swivel joint, hollow vertical shaft and the rotation bistrique and communicated;
