Abstract
The invention relates to a production method of a concrete conveying pipe. The production method comprises the steps that the baiting length of a seamless pipe is lengthened, the volume of the seamless pipe with the lengthened length is identical to the volume of added materials of two pipe openings, two ends of the seamless pipe are respectively heated, then the pipe openings are formed through mold forging, and the concrete conveying pipe without welding beads is produced. The technical process of the concrete conveying pipe production is simple, the welding is not needed, no welding defects exist, high efficiency and environment protection are realized, the pipe opening intensity is high, and the verticality of the pipe openings and the pipeline axis is good.
Description
Technical field
The present invention relates to a kind of concrete delivery pipe, particularly the production method of this kind concrete delivery pipe.
Technical background
Along with the development of China's infrastructure construction and real estate industry, increasing to the demand of pump concrete and concrete delivery pipe.Concrete delivery pipe comprises one section wear-resisting seamless pipe and two mouths of pipe; The production method of existing concrete carrier pipe is with the method for welding seamless pipe to be connected with the mouth of pipe; This production method production process is many, cost is high, be prone to the mouth of pipe and seamless pipe off plumb quality problems, and welder's operating technology level directly influences the welding bead quality; Cause the weld cracking of carrier pipe easily, personal injury is produced and is caused in the influence construction.
Summary of the invention
In order to overcome the deficiency of prior art, the invention provides that a kind of technology is simple, the production method of the concrete delivery pipe of high efficiency, safety, environmental protection.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of production method of concrete delivery pipe; Employing extends the seamless pipe cutting length; The seamless pipe volume of extension length equates with the volume that two mouths of pipe increase material; Two terminations of seamless pipe are heated respectively, and the method for the model excellent suitability for press forming mouth of pipe is produced the concrete delivery pipe that does not have welding bead then.
The invention has the beneficial effects as follows: the technical process of producing concrete delivery pipe is simple; Need not welding, efficient, environmental protection, the mouth of pipe and the seamless pipe of the concrete delivery pipe of producing are structure as a whole; There is not weld defect; Owing to the reason of heating forging and pressing has been strengthened the intensity of the mouth of pipe, and forging equipment can guarantee the perpendicularity in the mouth of pipe and pipeline axle center, effectively overcome the deficiency of existing concrete carrier pipe production method.
Description of drawings
Fig. 1 is a concrete delivery pipe structural representation among the present invention;
Fig. 2 is a seamless pipe blanking sketch map among the present invention;
Fig. 3 is an excellent suitability for press forming sketch map among the present invention;
The corresponding relation of Reference numeral and title is among Fig. 1 and Fig. 2: 1 seamless pipe; 2 mouths of pipe; 41 forging and pressing core rods, 42 forging and pressing split cavities, L are that concrete delivery pipe length, L ' are blanking lengthening section length.
The specific embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, the present invention is described in detail below in conjunction with the accompanying drawing and the specific embodiment:
Concrete delivery pipe structural representation among Fig. 1 comprises one section seamless pipe 1, two mouths of pipe 2, and concrete delivery pipe length is L.
Seamless pipe blanking sketch map among Fig. 2 is produced the concrete delivery pipe of length as L in order to use the mould forging and pressing, and the cutting length of seamless pipe 1 has increased by the length of two L ', and the volume of each L ' length seamless pipe 1 equates with the volume that the mouth of pipe 2 increases material.
After two terminations heating with seamless pipe 1,, seamless pipe 1 is clamped in the appropriate location, termination with forging and pressing split cavity 42 respectively according to method shown in Figure 3, with this terminations of forging and pressing core rod 41 squeezing seamless pipes 1 to forming the mouth of pipe 2.
The invention of the production method of this concrete delivery pipe produce concrete delivery pipe; Do not have weld defect, the mouth of pipe and seamless pipe are structure as a whole, and technical process is simple; Efficiently, environmental protection; The intensity of the mouth of pipe is high, and the perpendicularity in the mouth of pipe and pipeline axle center is good, has effectively overcome the deficiency of existing concrete carrier pipe production method.
Claims (2)
1. the production method of a concrete delivery pipe is characterized in that: adopt two terminations of seamless pipe are heated respectively, then the method for the model excellent suitability for press forming mouth of pipe.
2. the production method of a kind of concrete delivery pipe according to claim 1 is characterized in that: with seamless pipe cutting length lengthening, the seamless pipe volume of extension length equates with the volume of two mouths of pipe increase materials.
