Abstract
The invention discloses an end die of a reinforced concrete drainage pipe die. The end die comprises an end die body; the end die body consists of an inner ring and an outer ring; radial threaded holes are uniformly distributed in the hole wall of the inner ring; threaded holes opposite to the radial threaded holes in the hole wall of the inner ring are uniformly distributed in the inner wall of an annular groove of the outer ring; and screws are matched with the threaded holes in the inner ring and the outer ring. The inner ring is made of hard alloy. Compared with the prior art, the end die has the advantages of long service life and low replacement cost.
Description
Technical field:
The present invention relates to a kind of concrete forming mould, particularly a kind of end mould of reinforced concrete sewer pipe pipe die.
Background technology:
Concrete or reinforced concrete drainpipe finishing die are made up of mould tube and end mould, when tubulation, nib internal frame on the pipe die, on the hollow shaft of Suspension rolling machine, hollow shaft drives end mould high speed rotating, thereby drive whole pipe die rotation, conveyer belt is sent into the concrete material that stirs and is made drainpipe in the pipe die, because the friction between end mould and the hollow shaft is violent, the endoporus serious wear of end mould when the wearing and tearing back aperture increases and distortion, causes the tube wall attenuation of the drainpipe made to form waste product, the service life of this end mould is shorter, has increased cost and has reduced production efficiency simultaneously.
Summary of the invention:
The purpose of this invention is to provide a kind of end mould of changing the low a kind of reinforced concrete sewer pipe pipe die of end mould expense, realize that purpose technical scheme of the present invention is, a kind of end mould of reinforced concrete sewer pipe pipe die, comprise the end die body, it is characterized in that: described end die body is made up of inner ring and outer ring, be evenly equipped with radial screw bore on the hole wall of inner ring, be evenly equipped with on the cannelure inwall of outer ring with described inner ring hole wall on the relative screwed hole of radial screw bore, the screwed hole on screw and above-mentioned inner ring and the outer ring matches.Described inner ring is made by carbide alloy.The present invention has end mould long service life and the low remarkable advantage of renewal cost compared with the prior art.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
The present invention is described in detail in conjunction with above-mentioned accompanying drawing, the defective that needs to change the end mould in order to overcome end the touching the hole quick abrasion of mould, to hold mould to be divided into internal mold circle 3 and outer die ring 1, radial screw bore is uniformly distributed along the circumference on the hole wall of this internal mold circle, the identical screwed hole of radial hole on uniform and above-mentioned inner ring hole wall on the inwall of the cannelure of this outer die ring, screw 2 matches with screwed hole on above-mentioned inner ring and the outer ring.When inner ring hole wearing and tearing are heavier when needing to change, twist that screw can take out inner ring and the inner ring that more renews synthesizes new end mould.Body structure end mould only need be changed inner ring and not need to change the outer ring in this minute, thereby had saved the expense of changing the end mould.To hold service life because of more holding mould to reduce the defective of production efficiency in order overcoming, can to adopt high abrasion resisting material such as carbide alloy to make inner ring.
Claims (2)
1. the end mould of a reinforced concrete sewer pipe pipe die, comprise the end die body, it is characterized in that: described end die body is made up of inner ring and outer ring, be evenly equipped with radial screw bore on the hole wall of inner ring, be evenly equipped with on the cannelure inwall of outer ring with described inner ring hole wall on the relative screwed hole of radial screw bore, the screwed hole on screw and above-mentioned inner ring and the outer ring matches.
2. the end mould of a kind of reinforced concrete sewer pipe pipe die according to claim 1 is characterized in that: described inner ring is made by carbide alloy.
