Abstract

Disclosed is a moving concrete drain-pipe moulder. A mould, presser feet, a guide column, a transmission device are arranged in a frame style machine frame, the lower part of which is provided with a roller. The mould is an integration fixing the inner and the outer moulds together, the circular presser feet are matched with the interstice between the inner and the outer moulds, and the mould and the presser feet are respectively controlled to rise and fall along the guide column by the screw rod which is connected with the transmission device. The precast unit is pressed by the presser feet after moulding, the mould is lifted, and the precast unit stays in situ after demoulding, the machine frame is moved to a new station. The utility model has the advantages of simple structure and convenient operation, suitable for mid and minitype prefabrication factories to produce drain pipes of 300 to 1000 millimetres.

Description

Moving concrete drain-pipe moulders

The utility model belongs to a kind of forming machine of concrete preform, exactly is a kind of mobile concrete drain pipe forming machine, is fit to produce the concrete drain tile of 300～1000 millimeters of diameters.

The present concrete drain tile of domestic production diameter more than 400 millimeters, at the big-and-middle-sized centrifugal pressure type make-up machine that shakes of the many employings of system factory that gives, it is by an axle drive pine cover external mold thereon rotation together of rotation at a high speed, axle is equivalent to internal mold, utilize the extruding of centrifugal force and axle to make formed product, this device needs supporting crane, driving, Industrial Boiler, steam-cured pond and tall and big factory building, the external mold that must have sufficient amount to migrate for week in addition, investment is big, the energy consumption height.The general small-sized system factory that gives then uses removable many lobes mould, hand charge, and the manpower tamping, labor strength is big, and efficient is low, unstable product quality, waste of raw materials is serious.

The purpose of this utility model is the former that gives designing a mechanism of system factory for middle-size and small-size, and this device structure is simple, and is easy to operate, and power consumption is few, and can guarantee product quality.

Large diameter drainpipe is manually removed motionless, but does not want by big machinery, stays so the utility model imagination will be given the drainpipe original place demoulding that makes, and mold integral is shifted, so need inside and outside mould is fixed together, design an annular presser feet again, treat drainpipe give make after, presser feet is pushed down drainpipe, inside and outside mould upwards promotes simultaneously, and integral body unloads, and gives the system body after the demoulding and just stays the original place, the displacement mould, repetitive operation.

Specifically the utility model is that mould, presser feet, guide pillar and transmission device are arranged in the frame of a tower structure, four rollers is housed below the frame, and whole frame can be moved on ground.Mould promptly is two diameter differences but identical coaxial being linked in together of cylinder (being inside and outside mould) of length, the difference of external mold inside radius and internal mold outer radius promptly is the wall thickness of preform, two moulds are fixed in an end, at least get three fixing points, and symmetrical substantially, stiff end is upwards during installation, external mold is connected on the guide pillar by sliding sleeve, internal mold is equipped with vibrator, and connects with an end that promotes screw mandrel, and the other end of this screw mandrel connects with the transmission device; The presser feet of an annular is contained in the top of mould and coaxial with mould, the wide gap that is slightly less than between the inside and outside mould of presser feet, on the correspondence position of presser feet, cut gap with respect to mould bearing, just this annulus is made up of the circular arc of three basic symmetries at least, so that the fixing point with mould when pressing down staggers, presser feet is fixed on the presser feet seat, the presser feet seat is connected on the guide pillar by sliding sleeve, and by the end connection of a spring with the presser feet screw mandrel, the other end of this screw mandrel connects with the transmission device; Two rhizoid bars are coaxial, the thick and hollow of presser feet screw mandrel, and it is thinner to promote screw mandrel, passes the presser feet screw mandrel; At least two of guide pillars are symmetrically distributed substantially with respect to frame axis; Transmission device is positioned at the top or the top of frame.

For making uniform machinery can produce the drainpipe of different size, mould and corresponding presser feet should be able to be changed, for this reason mould with guide pillar and lifting screw mandrel be connected and presser feet be demountable with the connection or the presser feet seat of presser feet seat with being connected of guide pillar and spring.

The utility model compact conformation is made simply, and is easy to operate during production, do not need other auxiliary equipment, and labor strength is little, production efficiency height, finished product rate height.

Accompanying drawing is a structural representation of the present utility model, and part section among the figure points out that vibrator and the internal mold in the internal mold illustrated with the connection that promotes screw mandrel.

1, mould; 2, roller; 3, frame; 4, guide pillar; 5, vibrator; 6, sliding sleeve; 7, presser feet; 8, presser feet seat; 9, spring; 10, presser feet lifting actuator is connected with short, thick presser feet screw mandrel; 11, mould lifting actuator is connected with thin, long lifting screw mandrel.

With 800 millimeters concrete drain tiles of processing diameter is example, and in conjunction with the accompanying drawings, embodiment is described below:

No. 16 channel-section steels of frame 3 usefulness are welded into tower structure, four rollers that diameter is 420 millimeters be contained in frame 3 below.

Axis installation mold 1, presser feet 7 along frame 3.The steel plate of mould 1 usefulness 5 millimeters thick is rolled into, 952 millimeters of external mold internal diameters, 800 millimeters of internal mold external diameters, long 1150 millimeters, at 100 millimeters places of distance upper edge hole to taking by weighing 3 points, on external mold inwall and internal mold outer wall, weld one thick 25 millimeters, wide 60 millimeters gusset piece respectively, fix with the hexagon socket head cap screw of M12 * 50.The internal mold upper end is circular cone top, forms charge door with the external mold upper edge, welds a gusset piece at the vertex of a cone, connect with an end that promotes screw mandrel, 1.5 kilowatts of YZL vertical of adorn vibrating motors in it and make vibrator 5, the external mold outer wall connects with four sliding sleeves 6 with bolt, and four sliding sleeves 6 are enclosed within on the guide pillar 4 in twos respectively; Guide pillar 4 has two, and 60 millimeters of diameters process with thick-walled pipe; The steel plate of presser feet 7 usefulness 20 millimeters thick is processed into three sections identical circular arcs, and wide 70 millimeters steel pipes by 50 millimeters of three diameters are fixed by bolts on the presser feet seat 8; Presser feet seat 8 promptly is a disk, two sliding sleeves 6 by symmetry connect with guide pillar 4, there are some groups of apertures of symmetry to be distributed on the concentrically ringed circumference of different-diameter on the disk,, connect the presser feet screw mandrel by spring 9 at circle centre position so that change the presser feet 7 of different size; Lifting actuator 10,11 promptly is a mechanical reduction gear, is connected with an end that promotes screw mandrel with the presser feet screw mandrel respectively, and two transmission devices are fixed on the top of frame 3,1.1 kilowatts of and each mates the motor of.

Operating process is as follows: mention presser feet 7, quantifying feed in mould 1, Vibration on Start-up device 5, after several minutes, presser feet 7 presses down, and treats to stop vibration after the closely knit moulding of preform, starts die lifting device 11, mould 1 is risen, after the demoulding, promote presser feet, moving frame is to new station, put down mould 1, but just repetitive operation.
