Abstract

The utility model discloses a ring-shaped roller mould induction heating device on a cold-rolling tube mill, which is mainly used for solving the problem of the assembling and disassembling of a ring-shaped roller mould. The device comprises an induction heater and an electric control cabinet, wherein the induction heater comprises a solenoid induction coil, a shell, an operation button, a lifting ring, an electric wire and cable and a bearing bolt, wherein the solenoid induction coil is mounted in the shell; the lifting ring and the operation button are mounted on the upper surface of the shell; the bearing bolt is mounted below the shell; and the electric wire and cable is connected with the electric control cabinet. The ring-shaped roller mould induction heating device is made by using the principle that the solenoid induction coil generates vortex due to induction in the ring-shaped roller mould after switching alternating current on, so that the inner hole of the roller mould is subject to thermal expansion. Therefore, the utility model has the characteristics of quickness, high efficiency, low possibility of mating member surface damage, and the like. The utility model is applicable to the assembly and disassembly of ring-shaped roller moulds on the cold-rolling tube mills.

Description

Annular roll mould induction heating apparatus on the cold pilger mill

Technical field

The utility model relates to a kind of heater, particularly relates to a kind of induction heating apparatus.

Background technology

Annular roll mould on the cold pilger mill is along with different rolling specs need be changed corresponding roll mould at present, at least need two to three people and generally assemble or dismantle an annular roll mould, just can finish through heavy operation of a few hours, and in operating process, be easy to squeeze and hinder or the plucking matching surface, influence the service life of roll mandrel or annular roll mould.

The utility model content

The purpose of this utility model is that a kind of induction heating apparatus will be provided, and in order to solve existing problem in the annular roll mould cargo handling process, discloses the annular roll mould induction heating apparatus on a kind of cold pilger mill.

The utility model is achieved in that the annular roll mould induction heating apparatus on a kind of cold pilger mill comprises induction heater and electric control box two major parts; wherein induction heater is by solenoidal inductor; insulation protection housing (hereinafter to be referred as housing); action button; hoisting ring; electric wire and load-bearing latch; solenoidal inductor is loaded in the housing; hoisting ring is loaded on supplying/heating system lifting usefulness on the housing upper surface; action button is loaded on and makes power switch usefulness on the housing upper surface; the load-bearing latch is loaded on the housing below also can be left; the right slip with stationary annular roll mould, electric wire is connected with electric control box.Working time, electric current, operation control supervisor that electric control box is mainly used in induction heater are operated, are controlled and show.

Above-described machinery, parts such as electric are the commercial goods except that having stated, the utility model is not described further.

Comparing its outstanding advantage with conventional method according to the annular roll mould induction heating apparatus on the cold pilger mill of technique scheme making is: 1, have rapidly and efficiently, do not damage the advantage on counterpart surface; 2, assemble at every turn or dismantle an annular roll mould, only need one man operation and can be accurately in 5-8 minute, easily finish high efficiency.

Description of drawings

Annular roll mould induction heating apparatus structural representation on Fig. 1, the cold pilger mill.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further narration.

As shown in Figure 1; annular roll mould induction heating apparatus on the cold pilger mill comprises induction heater and electric control box; wherein induction heater comprises solenoidal inductor 8, insulation protection housing 7, action button 6, hoisting ring 5, electric wire 2 and load-bearing latch 1; solenoidal inductor 8 is loaded in the housing 7; hoisting ring 5 is loaded on the housing upper surface; action button 6 is loaded on the upper surface of housing; load-bearing latch 1 is loaded on the below of housing and can left and rightly slides, and electric wire 2 is connected with electric control box.The electric control box outsourcing as long as possess safeguard protection, time showing, electric current demonstration, operation and controlling unit etc., is not described further here.

According to the foregoing description, the roll mandrel 4 of the annular roll mould 3 that when the annular roll mould induction heating apparatus on the cold pilger mill is worked desire is assembled or dismantled steadily is placed on ground and fixedly to avoid overthrow accident, then induction heater is sling, be inserted in annular roll mould 3, and be fixed firmly with load-bearing latch 1, be hung in roll mandrel 4 the top (during dismounting together with roll mandrel 4 hang ground a little), everything is ready, and back start-up operation button is implemented heating, after utilizing solenoidal inductor to pass to alternating current, the endoporus of the axial alternating magnetic field of coil annular roll mould 3 after annular roll mould internal induction produces the short time heating of eddy current process can easily be sleeved on (roll mandrel 4 is taken off from annular roll mould 3 because of its deadweight during dismounting) on the roll mandrel 4 because of expanded by heating by its deadweight.

Claims
