Description

Forced vertical spinning concrete pipe-making machine

The utility model 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 with low cost, is a kind of farmland antiseepage pipeline of practicality.Produce existing spinning and upright two kinds of types of spinning of pressure of freely standing of concrete pipe-manufacturing machine of this water pipe.The spinning force that freely founds the spinning concrete pipe-manufacturing machine is limited, and the pipe degree of packing of making is relatively poor, rough surface, tube wall are thicker, its barrier performance, production efficiency and cost are all not satisfactory.Force upright spinning concrete pipe-manufacturing machine to set up pressure voltage stabilizing mechanism, seep water device and passive extruding running roller automatically, made water-supply-pipe tube wall is thinner, slurry consumption reduction, production efficiency improve, the water-supply-pipe degree of packing and barrier performance obviously improve.But it utilizes structural design of cam, clamping plate and extension spring control pressure roller to have in use that clamping force is little, the shortcoming of control ability difference, and the braking of hold-down roll is also undesirable.In addition, the bearing of the driven roll wheel shaft on the rotation bistrique easily advances slurry and damages, and all need improve.

Task of the present utility model forces upright spinning concrete pipe-manufacturing machine further to improve to existing exactly, makes that its performance is better, more reliable, the workpiece longer service life of operation.

For this reason, the technical solution of the utility model is, designed a kind of station rotating disk by frame and rack-mounted extruding assembly and frame lower, mould upper end positioning disk and transmission device, the concrete pipe-manufacturing machine that operating mechanism is formed, extruding assembly wherein comprises the rotation bistrique of band binder pin, vertical shaft and drive socket, there are swivel joint and square shaft bar in the vertical shaft upper end, the square shaft bar is by a pair of hold-down roll and a pair of pressure roller clamping, feed pipe classical prescription axostylus axostyle, swivel joint, hollow vertical shaft is crossed tank with the annular on the rotation bistrique and is communicated, on the plunger type water valve that is opened and closed by limit cam is arranged, between the binder pin on the rotation bistrique two passive running rollers of frustum type are arranged.Its main improvement one is on a pair of clamping wheel of clamping square shaft bar brake ribbon to be arranged all, and brake ribbon is single-ended fixing, and the other end and extension spring and clutch lever join.Make hovering of square shaft bar and bistrique more safe and reliable like this; The 2nd, intermeshing driving tooth fan and passive tooth fan are housed in the rotating shaft of a pair of pressure roller of clamping square shaft bar, two teeth fan radius sum is greater than two pressure roller radiuses and square shaft thickness sum, and the pressure roller axle is bearing on the slide, and there is stage clip in the roller wheel rim outside.Like this, the manipulation of pressure roller is more reliable, and the clamping force of the other side's axostylus axostyle also obviously improves, and can improve the degree of packing of pipe of cement.

For avoiding rotating the driven roll wheel shaft premature wear on the bistrique, can make the wheel shaft of passive running roller pass the bistrique areole, be installed on the bistrique rolling bearing, between rolling bearing and the bistrique sidewall 5-10 mm clearance is arranged, slurry just can not enter bearing like this, thereby prolongs the life-span of rolling axle and bearing.

Further describe the utility model below in conjunction with accompanying drawing.

Fig. 1 is that the utility model embodiment forces upright spinning tuber schematic diagram.

Fig. 2 is a clamping device schematic diagram of forcing upright spinning tuber.

Fig. 3 is a rotation bistrique schematic diagram of forcing upright spinning tuber.

As shown in Figure 1, rotating station rotating disk 25 is arranged at the bottom of tubulation frame 5.Open-close type pipe die 24 is placed on the station rotating disk 25, and mould upper end location-plate 2 is withheld on pipe die 24.From location-plate 2, can in pipe die 24, dose the concrete slurry.The rotation bistrique 23 of extruding assembly 16 lower ends is driven by hollow vertical shaft 19, can move up and down in mould pipe 24.Extruding assembly 16 and rotation bistrique 23 are driven through speed changer 4 by motor 3.The hollow vertical shaft 19 of extruding assembly 16 and the upper end of drive socket 15 have square shaft bar 8 to be forced to spinning machine 9 clampings.In the square shaft bar 8 limbers is arranged, feed pipe 7 joins with square shaft bar 8, and the water pipes 14 of crossing in water classical prescription axostylus axostyle 8, the hollow vertical shaft 19 flow to rotation bistrique 23, when the spinning tubulation, the wet tube inwall, reduces friction, improves forming quality.Cross the water valve 13 that has on the water pipe 14 by limit cam 12 controls.When bistrique 23 dropped to pipe die 24 bottoms and begins spinning, water valve 13 was opened water supply.Bistrique 23 rises to setting height, and limit cam 12 promotes to close water valve 13, stops to supply water.

As shown in Figure 1 and Figure 2, square shaft bar 8 moves and hovers by control stick 10,11 controls of forcing spinning machine 9 are upper and lower.Forcing has a pair of pressure roller 30 and a pair of hold-down roll 31 in the spinning machine 9.The equal clamping square shaft of two pair rollers bar 8, pressure roller 30 is driven by motor 6, and square shaft bar 8 is at the uniform velocity risen with setting speed, rises thereby bistrique 23 rotate on one side, and keeps a constant downforce, realization pressure spinning.Intermeshing driving tooth fan 26 and passive tooth fan 36 are housed in the rotating shaft 29 of pressure roller 30, two teeth fan radius sum is greater than two pressure roller radiuses and square shaft 8 thickness sums, pressure roller axle 29 is bearing on the slide 27, and there is stage clip 28 in the pressure roller 30 wheel rims outside.Control operating rod 11 can change the chucking power of two pressure roller, 30 the other side's axostylus axostyles 8.Brake ribbon 32 is all arranged on the hold-down roll 31, and brake ribbon 32 is single-ended fixing, and the other end is connected with trip(ping) lever 33 with extension spring 25, operates pull bar 10 and can brake or unclasp hold-down roll 31, makes bistrique 23 upper and lower or hover.

As shown in Figure 3, the wheel shaft 39 of the passive running roller 22 on the rotation bistrique 23 passes bistrique sidewall 37, is installed on the rolling bearing in the bistrique 23, between rolling bearing 38 and the bistrique sidewall 37 the 5-10 mm clearance is arranged.
