Abstract

The invention relates to the field of concrete pipe manufacturing, in particular to a concrete drain pipe production device using the roller suspension method. The concrete drain pipe production device comprises a roller shaft, a pipe die, a rear end die and a front end die, wherein the rear end die and the front end die are connected with the two ends of the pipe die respectively. The concrete drain pipe production device is characterized in that a rotating die which can rotate freely around the roller shaft is arranged at the front end of the roller shaft, the outer contour of the rotating die corresponds to the contour of an insertion opening of a concrete drain pipe, annular protruding edges which have the same inner diameter and are coaxial with each other are arranged on the rear end die and the front end die respectively, and the annular protruding edges are borne by the roller shaft. According to the concrete drain pipe production device, direct roller pressing forming of a whole pipe body is achieved, and therefore rapid demolding can be achieved after bell end type drain pipes and rabbet type drain pipes are formed. Meanwhile, the two ends of the roller shaft drive the pipe die at the same speed to enable the pipe die to rotate, the problem that the concrete drain pipe production device is difficult to start and even can not start in the production is solved, and therefore the drain pipes with large lengths, large hole diameters and heavy weights can be produced.

Description

Concrete drain tile process units

Technical field

The present invention relates to concrete pipe field, specifically concrete drain tile process units.

Background technology

Roller-suspending is the conventional process of making concrete drain tile.While producing flat drainpipe, this technique, because using dry concrete compound, can realize fast demoulding.But when producing spigot-and-socket and groove and tognue type drainpipe, because using the pipe die with bellmouth internal mold, there are the following problems: (1) must be larger than the mixture moisture content of its elsewhere body because dropping into the concrete mixture of socket, and material need stir separately herein, has increased workload.(2) because roll shaft can not directly apply radial pressure to the concrete of socket, the extruding force extrusion modling that bellmouth only depends on pipe shaft concrete to transmit, so packing is poor.(3) after drainpipe moulding, because socket concrete is wetter, as by making flat drainpipe method, immediately pipe is inverted together with pipe die, then is removed die body, socket concrete can not bear body concrete gravity and cave in.

Chinese patent ZL97219236.0 discloses a kind of plug-in adapted concrete drainage pipe production equipment.(as shown in Figure 1) this device on overhang-roll tubing machine main shaft, be arranged with conform to Concrete Drainage Pipe bellmouth shape and can make runner in relative rotation with main shaft, female end is connected with a ring flat-plate shape bellmouth die head, and the upper lateral part of ring flat-plate shape bellmouth die head inner edge contacts with the upper lateral part of runner outer rim.By the concrete of runner outer rim extruding socket, guarantee that the packing of socket concrete is consistent with other place.This device is short in production length, bore is little, during lightweight drainpipe, can, by the concrete of runner outer rim extruding socket, make the packing of socket concrete consistent with other place.

The shortcoming of this patent is: because the female end of pipe die is by the runner support on main shaft, and runner can not drive the rotation of pipe die, can only lean on another to bring in driving.So the problem that exists difficulty in starting even can not start production length is slightly long, bore large, during the drainpipe of Heavy Weight, shuts down especially in process of production for some reason, in the time of need restarting, situation is more obvious again.

Summary of the invention

Technical problem to be solved by this invention is: while producing spigot-and-socket or groove and tognue type concrete drain tile, although form removal or the problem that can quick form removal be only applicable to produce small-sized drainpipe fast.

Concrete scheme is: concrete drain tile process units, comprise roll shaft, pipe die and the rear end mould and the front end mould that are connected with described pipe die two ends respectively, it is characterized in that: described roll shaft front end is provided with the revolving die that can freely rotate around roll shaft, described revolving die outline is corresponding with concrete drain tile socket profile, described rear end mould is respectively equipped with the identical and coaxial convex annular edge of internal diameter with front end mould, described convex annular along support on described roll shaft.

Described revolving die is socketed by bearing and described running roller.

For convenience of installing, reduce the diameter of roll shaft rear end, described roll shaft is support roller before front end mould part described in support is provided with, and described front support roller is fixedly connected with described roll shaft.

Further, described front support roller external diameter equals the external diameter of described revolving die.

Further, described roll shaft is support roller after rear end mould part described in support is established, and described rear support roller is fixedly connected with described roll shaft, and described rear support roller external diameter equals the external diameter of described front support roller.

For adapting to the interface modes of tongue and groove, rear end mould is provided with the groove that is suitable for producing groove and tognue type concrete drain tile.

Feature of the present invention is: whole working condition is the same with the flat mouth pipe mode of production, has realized the direct roll-forming of full body, makes mouthing and groove and tognue type drainpipe can realize fast demoulding after moulding; Simultaneously roll shaft two ends, with same speed drive pipe die rotation, have solved the problem that in producing, difficulty in starting even can not start, therefore can production length compared with long, bore is large, the drainpipe of Heavy Weight.
