Abstract

The utility model discloses an induction heating device of the annular roller die of two-roller type cold-rolling pipe mill which is primarily used for loading and unloading of the annular roller dies. The device consists of an induction heater and an electric control box, wherein, the induction heater consists of a spiral cord ring, an insulating protection shell, an operation button, a slinging ring, a wire and cable, and a bearing inserted pin. The spiral cord ring is arranged in the shell, and the operation button and slinging ring are arranged on the surface of the shell, and the bearing inserted pin is arranged below the shell to fix the roller die. A solenoid induction coil is applied to the annular roller dies induction heating device, and the axial alternative magnetic field of the coil induces vortex in the annular roller die when electrifying with alternating current, thereby the inner hole of the roller die expanding when heated, which is the theory of the utility model. The device has the advantages of fast and efficient heating result, and no damage to the matching surface.

Description

Annular roll mould induction heating equipment

One, technical field

The utility model relates to cold pilger mill, particularly relates to the loading and unloading of the annular roll mould of two-high cold-rolling pipe mill.

Two, background technology

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

Three, summary of the invention

In order to address the above problem, the utility model provides a kind of annular roll mould induction heating equipment.This annular roll mould induction heating equipment is made up of induction heater and electric control box two major parts.Wherein induction heater is made up of solenoid, insulation protection housing (hereinafter to be referred as shell spare), action button, hoisting ring, electric wire and load-bearing latch etc.; solenoid 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 controls the induction heater energising not on the housing upper surface; the load-bearing latch is loaded on the housing below and can left and rightly slides; with stationary annular roll mould, electric wire is connected with electric control box.Operating time, electric current, operation and control supervisor that electric control box is mainly used in induction heater are operated, are controlled and show.

Comparing its outstanding advantage with traditional mechanical pressurization according to the annular roll mould induction heating equipment of technique scheme making is: 1, have rapidly and efficiently, do not damage the advantage of matching surface; 2, assemble at every turn or dismantle an annular roll mould, only need one man operation can be accurately in 5～8 minutes, easily finish.

Four, description of drawings

Fig. 1, annular roll mould induction heating equipment structural representation.

Five, embodiment

Below in conjunction with accompanying drawing 1, describe a kind of execution mode of annular roll mould induction heating equipment in detail.As shown in Figure 1; annular roll mould induction heating equipment is made up of induction heater and electric control box; wherein induction heater is made up of solenoid 8, insulation protection housing 7 (hereinafter to be referred as housing), action button 6, hoisting ring 5, electric wire 2 and load-bearing latch 1 etc.; solenoid 8 is loaded in the housing 7; hoisting ring 5 is loaded on the upper surface of housing 7; action button 6 is loaded on the upper surface of housing 7; load-bearing latch 1 is loaded on the housing below and can left and rightly slides; with stationary annular roll mould, electric wire 2 is connected with electric control box.The electric control box outsourcing, as long as possess safeguard protection, time showing, facilities such as electric current demonstration, operation and controlling unit get final product, and are not described further here.

Press the foregoing description, during the work of annular roll mould induction heating equipment, the roll mandrel 4 of the annular roll mould 3 that desire is assembled or dismantled steadily is placed on the 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 6 is implemented heating, after utilizing solenoidal inductor to pass to alternating current, the axial alternating magnetic field of coil produces eddy current at annular roll mould internal induction, the endoporus of the annular roll mould 3 in process heating blink back 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

1, a kind of annular roll mould induction heating equipment of forming by induction heater and electric control box; it is characterized in that induction heater is made up of solenoid (8), insulation protection shell (7), action button (6), hoisting ring (5), electric wire (2) and load-bearing latch (1); wherein solenoid (8) is loaded in the housing (7); hoisting ring (5) is loaded on the upper surface of housing (7); action button (6) is loaded on the upper surface of housing (7); load-bearing latch (1) is loaded on the housing below and can left and rightly slides, and electric wire (2) is connected with electric control box.
