Abstract

The utility model relates to a concrete-pipe forming machine immediately demoulded, belonging to the field of concrete-pipe forming appliances. The machine solves the problem that after products are formed, the existing forming mechanism has to be steamed with a mould before demoulding. The utility model is composed of a machine frame, an inner mould, an outer mould, a vibration exciter and a pressing smearing mechanism. A detachable concrete-pipe blank support ring is arranged between the lower parts of the inner mould and the outer mould. In demoulding process, the concrete pipe, the outer mould and the concrete-pipe blank support ring are all lifted and moved to a curing field; the concrete-pipe blank support ring is loosened, and the outer mould is lifted up, so as to complete the demoulding process. The forming machine with reasonable structural design and convenient operation can be used for producing various shaped concrete pipes.

Description

Demoulding concrete pipe forming machine at once

The utility model relates to a kind of concrete pipe forming apparatus field, is exactly a kind of moulding material adding pattern or equipment are not interior to make the device of moulded products, exactly is a kind of concrete of the demoulding at once pipe forming machine.

Existing concrete pipe former mainly contains two kinds in centrifugal molding machine and roller suspension process machine.There is following several respects problem in described two kinds of concrete pipe forming machines: the one, after the moulding, need the steam-cured certain hour of band mould, and can form removal; Two moulds after being to use need be cleaned out, and the brushing spacer can continue to use; The 3rd, mould mostly is double openings type (Hafu type), seldom uses single radial cut, can't use the imperforation monoblock type; The 4th, can only produce cylindrical tube, can't produce special pipe, the 5th, the energy consumption height, noise is big.Chinese patent 89206523.0 discloses the mobile concrete drain pipe forming machine, and 93203560.4 disclose make-up machine of concrete drain pipe with automatic demoulding function, described two utility model patents also in various degree have an above-mentioned problem.

The purpose of this utility model is: the demoulding immediately after a kind of moulding is provided, and need not to clear up mould, the concrete of the demoulding at once pipe forming machine of brushing spacer.

The technical solution that realizes above-mentioned purpose is such: this concrete pipe forming machine, and smear mouth mechanism by frame, internal mold, external mold, vibrator and pressurization and form.Frame is the bottom that frame-type is located at foundation ditch, and foundation ditch is recessed formula hole, can locate below ground level.Internal mold is located on the frame, and the middle part of internal mold is provided with vibrator, and the lower end of internal mold outer surface is provided with concrete conduit saddle tread ring.External mold is located at the periphery of internal mold, and is positioned on the concrete conduit saddle tread ring, and uniform between external mold and the concrete conduit saddle tread ring plural claw is arranged.

Pressurization is smeared mouth mechanism and is smeared mouthpart by rotating beam, column and pressurization and form, and column is located at any side on plane on the foundation ditch; Rotating beam is crossed on the top on plane on the foundation ditch, and the one end is connected with column, and can rotate around column.Pressurization is smeared mouthpart and is located under the rotating beam, and its symmetrical center line is coaxial with the internal mold symmetrical center line.

External mold or be double openings type (Hafu type); Or be the single radial cut formula; Or be the imperforation monoblock type.

The die cavity of inside and outside intermode can be designed to cylindrical, avette, oval as required or be polygon.

The utlity model has the advantage of several respects:

One, after the concrete pipe is shaped, need not steam-cured, but the demoulding immediately is easy to operate, enhances productivity, and reduces energy resource consumption.

Two, the mould after the demoulding need not cleaning, and the brushing spacer can drop into circulation and produce, and saves the man power and material.

Three, can produce cylindrical concrete pipe, square concrete pipe, oval concrete pipe and other special-shaped concrete pipes as required.

Four, the external mold of this concrete pipe forming machine both can be double openings type, also can be the single radial cut formula, or was the imperforation monoblock type, had widened the scope of application.

Accompanying drawing is the utility model structural representation.

Below in conjunction with drawings and Examples the utility model is described further.

By the visible frame 8 of accompanying drawing are the frame-types that are welded into by shaped steel or steel plate, and foundation ditch 12 is a recessed formula hole, can be positioned at below the ground level, and frame 8 is contained in the foundation ditch 12.Internal mold 6 is by being bolted on the frame 8, and vibrator 7 is contained in the inner chamber of internal mold 6.Concrete conduit saddle tread ring 9 is placed on the bottom of internal mold 6 peripheries, and the claw 10 of ining succession is welded in the lower end, the outside of external mold 5 to 5 of external molds on concrete conduit saddle tread ring 9, and claw 10 extends the bottom of concrete conduit saddle tread ring 9, and external mold 5 and concrete conduit saddle tread ring 9 hooks are connected together.Column 4 is fixed on a side on the last plane of foundation ditch 12, and rotating beam 2 is crossed on the foundation ditch 12, and one end and column 4 flexibly connect, and can rotate in 180 °～360 ° scopes around column 4.Pressure is smeared the below that mouthpart 3 is contained in rotating beam 2, is connected with rotating beam 2, and its symmetrical center line is coaxial with the symmetrical center line of the internal mold 6 of its underpart, and hydraulic system 1 is contained on the rotating beam 2.

The specific operation process of this concrete pipe forming machine is such: at first push rotating beam 2 open, the framework of steel reinforcement that roll welding is good is placed in the die cavity, begins charging then, when treating that the concrete material reaches mould 1/4th height, start the vibrator 7 of 6 li of internal molds, then continue reinforcedly, treat that material reaches on the internal mold behind the open height, retracts rotating beam 2, primer fluid pressing system 1 orders about pressure and smears mouthpart 3 and drop on 11 mouthfuls of the concrete pipes, in vibration, apply the pressure that needs to concrete pipe 11, to 11 moulding of concrete pipe.Operate hydraulic system 1 again and make pressure smear the top that mouthpart 3 bounces back to inside and outside mould, push rotating beam 2 open, this moment, rotating beam 2 was the center turnback with column 4.Mould is opened in ensuing work exactly.Tangle lifting place of external mold 5 with the ground jack dogging, start ground jack, concrete pipe 11, concrete conduit saddle tread ring 9 and external mold 5 upwards rise simultaneously slowly, break away from internal mold 6 gradually, until being raised on the concrete pipe forming machine beyond the plane, then with concrete pipe 11, concrete conduit saddle tread ring 9 and external mold 5 together move to the maintenance place, open claw 10, itself and concrete conduit saddle tread ring 9 are separated.Start ground jack again, make its rising, at this moment, because of concrete pipe 11 weight greater than with the adsorption friction of external mold 5, external mold 5 has just broken away from concrete pipe 11 like a cork, the demoulding finishes.Above-mentioned external mold 5 is the imperforation monoblock type.
