Abstract
The invention discloses a rigid joint tongue-and-groove drain pipe forming die and belongs to a forming technology. The invention aims to provide the rigid joint tongue-and-groove drain pipe forming die, and a die pipe in the forming die can also be used for a flexible joint C-shaped steel bell-mouth drain pipe. According to the technical scheme, the rigid joint tongue-and-groove drain pipe forming die comprises the die pipe and left and right head sealing rings; right end holes of the die pipe are four step holes; the circumference of the right head sealing ring is provided with four step cylindrical surfaces matched with the surfaces of the four step holes at the right end of the die pipe; and the inner end face of the right head sealing ring is opposite to the inner end face of the left head sealing ring. The forming die is used for forming a concrete drain pipe.
Description
Technical field:
The present invention relates to a kind of pipe of cement finishing die, particularly a kind of rigid joint tongue and groove drainpipe finishing die.
Background technology:
The development in city is increasing to the discharge capacity of sewage, rainwater, drainpipe is bigger through requiring, country has issued standard (GB/T 11836-2009) to this Concrete and reinforced concrete drainage and sewer pipes, the most frequently used and concrete drain tile that consumption is maximum has three kinds in the standard: flexible joint C shaped steel bellmouth drainpipe, the flat mouthful drainpipe of rigid joint and rigid joint tongue and groove drainpipe, the length of tube of these three kinds of drainpipes is 2000mm, and the external diameter of pipe is all identical.Existing production with pipe die is that three kinds of pipe dies are produced this three kinds of drainpipes respectively, because caliber and length are all bigger, the used steel of every cover pipe die are very big, pipe die expense height, and occupied ground is big.
Summary of the invention:
The object of the invention provides a kind of rigid joint tongue and groove drainpipe finishing die, and the mould pipe in this shaping mould also can be used for the mould pipe of flexible joint C shaped steel bellmouth drainpipe.Realize that technical scheme of the present invention is, a kind of rigid joint tongue and groove drainpipe finishing die, comprise mould pipe and left and right end socket circle, it is characterized in that: the right-hand member hole of described mould pipe is four step-shaped holes, the step cylinder that the side face of described right end socket circle has four four step-shaped hole faces with mould tube right-hand member to match, the inner face of this right end socket circle is relative with the inner face of left end socket circle.The present invention has the remarkable advantage that mould pipe versatility is good, die cost is low compared with the prior art.
Description of drawings:
Fig. 1 is that existing flexible joint C shaped steel holds drainpipe finishing die structural representation, Fig. 2 is existing rigid joint tongue and groove drainpipe finishing die structural representation, Fig. 3 is a rigid joint tongue and groove drainpipe finishing die structural representation of the present invention, Fig. 4 is a flexible joint C shaped steel bellmouth drain structure schematic diagram, Fig. 5 is a rigid joint tongue and groove drain structure schematic diagram.
The specific embodiment:
The present invention is in order to solve the shared problem of mould pipe in flexible joint C shaped steel bellmouth drainpipe and the rigid joint tongue and groove drainpipe shaping mould, to the mould pipe in these two kinds of finishing dies relatively, the left end hole of the former mould pipe 2 is identical with the latter's mould pipe 5 left end holes, the end socket circle of changing left end can be formed separately above-mentioned two kinds of different drainpipes, but the inner surface structure of the right-hand member of these two kinds of mould pipes is inequality and both right end socket circles 1,4 is also inequality, for this reason, right end socket circle 4 in the existing rigid joint tongue and groove drainpipe finishing die is replaced by right end socket circle 7 of the present invention, the structure of this right end socket circle is, the outer peripheral face of end socket circle is four step surfaces that the mould pipe right-hand member inner surface with flexible joint C shaped steel bellmouth drainpipe matches, the annular end face of its right-hand member is relative with left end socket circle 6, at this moment, distance between the inner face of left and right sides end socket circle should remain 2000mm, for the length of the mould pipe that makes flexible joint C shaped steel bellmouth drainpipe shaping mould also can be used for flat mouthful of drainpipe finishing die of rigid joint of the present invention, its length suitably need be extended, generally within the 50mm scope, can meet the demands, when formed flexible joint C shaped steel bellmouth drainpipe, axial length to the left end socket circle 3 of finishing die correspondingly extends, and the length that both increased is identical.
Claims (1)
1. rigid joint tongue and groove drainpipe finishing die, comprise mould pipe and left and right end socket circle, it is characterized in that: the right-hand member hole of described mould pipe is four step-shaped holes, the step cylinder that the side face of described right end socket circle has four four step-shaped hole faces with mould tube right-hand member to match, the inner face of this right end socket circle is relative with the inner face of left end socket circle.
