Abstract
The utility model discloses a large bore diameter electric melting sleeve pipe fitting. Wires are arranged on the inner wall of the pipe fitting. A mounting hole is formed in the outer wall of the pipe fitting. A wire connection terminal is arranged in the mounting hole in an inserted mode. Wires are connected with the wire connection terminal. The wires are fixed on the inner wall of the pipe fitting through a method of secondary injection molding. By adopting the structure and due to the facts that the wires are fixed on the inner wall of the pipe fitting through the method of secondary injection molding and the pipe fitting is formed by machining molded tubing on a lathe, an injection molding machine with lower tonnage can be used in the productive process of the large bore diameter electric melting sleeve. Thus invested cost is reduced and the molding cycle is shortened.
Description
Technical field
The utility model relates to a kind of heavy caliber electric melting sleeve.
Background technique
The heavy caliber electric melting sleeve of existing structure all is to adopt the mode of production of integrated injection molding and the wiring of Special wiring machine to produce, and namely uses first large-tonnage injection machine injection molding pipe part semi-finished product, use again the Special wiring machine with wire cloth on the inwall of semi-finished product pipe fitting.This mode of production deficiency is: need large-tonnage injection machine and Special wiring machine, input cost is high, and the product injection cycle is long.The utility model provides a kind of new heavy caliber electric melting sleeve to be intended to address the above problem for this reason.
The model utility content
In order to address the above problem, the utility model provides a kind of heavy caliber electric melting sleeve.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of heavy caliber electric melting sleeve comprises pipe fitting, is provided with wire on the described pipe fitting inner wall, be provided with mounting hole on the described pipe fitting outer wall, be inserted with terminal in the mounting hole, wire is connected with terminal, and described wire is fixed on the pipe fitting inner wall by the mode of quadric injection mould.
Described mounting hole and terminal respectively are provided with two, and wherein terminal are provided with the identification resistance with heavy caliber electric melting sleeve welding parameter information.
Described wire is set to copper wire, and described wire wraps up rear by the PE layer and pipe fitting carries out quadric injection mould.
Also be provided with handle on the described pipe fitting outer wall, described handle is fixedly mounted on the pipe fitting outer wall by the mode of quadric injection mould.
The beneficial effects of the utility model are: the utility model of employing said structure is fixedly mounted on pipe fitting inner wall by the mode of quadric injection mould with wire, pipe fitting adopts shaping pipe to process at lathe, so that the utility model can use the lower injection machine of tonnage in process of production, and molding cycle is short, do not need the wiring of Special wiring machine, greatly reduce input cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is erection drawing of the present utility model;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the local amplification view of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, the utility model is a kind of heavy caliber electric melting sleeve, comprise pipe fitting 1, be provided with wire 2 on pipe fitting 1 inwall, be provided with mounting hole on pipe fitting 1 outer wall, be inserted with terminal 4 in the mounting hole, wire 2 is connected with terminal 4, and wire 2 is fixed on pipe fitting 1 inwall by the mode of quadric injection mould; Wire 2 is set to copper wire, wire 2 by behind the PE layer parcel and pipe fitting 1 carry out quadric injection mould, some annular grooves 5 are set, so that material and pipe fitting 1 adhesive strength are higher during quadric injection mould on pipe fitting 1 inwall.The utility model production process is as follows: blank tubing is processed into the pipe fitting 1 that meets the utility model requirement at lathe, copper wire is wrapped on the core rod, core rod is put into pipe fitting 1, carry out quadric injection mould by injection machine.This shows and the utlity model has following advantage: can use in process of production the lower injection machine of tonnage, and after the injection moulding cool time short, can not deform in the cooling procedure.
As shown in the figure, mounting hole and terminal 4 respectively are provided with two, and wherein terminal 4 are provided with the identification resistance with heavy caliber electric melting sleeve welding parameter information.Identification resistance is used in conjunction with the electric welding machine with authentication function, just can automatically read the welding parameter of heavy caliber electric melting sleeve and automatically begin welding, save the time that manual input consumes, and the error that can avoid manually input to produce, increase work efficiency simultaneously.
As shown in the figure, for convenient carrying to the heavy caliber electric melting sleeve, also be provided with handle 3 on pipe fitting 1 outer wall, handle 3 is fixedly mounted on pipe fitting 1 outer wall by the mode of quadric injection mould.
Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
