Description
(1) technical field
The utility model relates to a kind of producing device of diamond rope saw, is in particular a kind of diamond rope saw injection moulding heater.
(2) technical background
Diamond rope saw is a kind of cutting tool, is widely used in construction material processing industries such as rock mining, the shaping of rock Waste stone material, shaped stone material processing and armored concrete cutting.Diamond rope saw is made up of beading, steel wire rope, immobilization material etc., and at present the most frequently used immobilization material is plastics, the mode of plastics by injection mo(u)lding with steel wire rope be through beading on the steel wire rope formation diamond rope saw that is fixedly connected.
In Shooting Technique; because when high temperature plastics touches normal temperature steel wire rope and metal die; the plastics temperature descends fast; its mobile i.e. reduction rapidly, plastics are difficult for infiltrating within the strand of steel wire rope, and the adhesive strength of plastics and steel wire rope reduces; the intensity that beading are fixedlyed connected with steel wire rope is reduced; it is loosening that product in use beading occur through regular meeting, and the plastics cracking comes off, so that the quality problems that rub of steel wire rope.Therefore at present in Shooting Technique the normal electric furnace heating that adopts steel wire rope is heated, avoid the plastics temperature to descend fast, with the flowability of improving plastics, improve the adhesion strength of plastics to steel wire rope.But present electric furnace heating exists three big shortcomings: 1, heating is inhomogeneous, and the steel wire rope external temperature is higher than inside, influences plastics and infiltrates in the steel wire rope strand; 2, heat time heating time fixing because the operating time difference of injection moulding process each time,, cause the quality instability of plastics solidification moulding so every section steel wire rope difference heat time heating time, temperature are inconsistent; 3, electric furnace is in "on" position always, and the thermal efficiency is low, the waste electric energy; 4, can't heat metal die, still influence the temperature of plastics.
Therefore need improved diamond rope saw injection moulding heater.
(3) utility model content
The purpose of this utility model is a kind of diamond rope saw injection moulding heater of design, making alive on steel wire rope and metal die, and the heat that its resistance produces during energising heats himself.
The utility model diamond rope saw injection moulding heater comprises injection machine, metal injection molded mould, injection mold is installed on the operating platform of injection machine, the steel wire rope that is installed with beading is sent in the mould from injection mold one side, this side at injection mold also has two contacts arranging along the steel wire rope direction, two end in contact for the treatment of the injection moulding section of contact and steel wire rope.Two contacts are connected with the output of pressure regulator.
The elementary connection travel switch and the electrotimer of the pressure regulator in the control circuit.During matched moulds, the travel switch closure, output voltage regulator is treated injection moulding section making alive, the heat heating that the energising of this section steel wire rope self produces, electrotimer control conduction time by two contacts to steel wire rope.Because steel wire rope resistance is very little, only needs the following low-voltage of 5v just can satisfy and add heat request, so this device is safe and reliable.By adjusting the output voltage of electrotimer and pressure regulator, can control conduction time and voltage that steel wire rope is treated the injection moulding section, promptly control its heating-up temperature.Therefore regulate electrotimer and pressure regulator can obtain the required steel wire rope optimum temperature of injection moulding, and conduction time and voltage remains unchanged, the heating-up temperature of every section steel wire rope is identical.
In order to prevent that contact and steel wire rope from producing discharge, also be connected to time-delay relay in the control circuit, behind the injection mold matched moulds 0.5～3 second, pressure regulator was connected in the time-delay relay action, and the beginning steel wire rope is treated the energising of injection moulding section.The then action in 0.5～3 second before die sinking of the time relay in the control circuit disconnects pressure regulator, stops the energising that steel wire rope is treated the injection moulding section.
In order to allow the temperature of mould raise, the output of another pressure regulator is connected with metal injection molded mould, makes it the energising heating and keeps uniform temperature.
The advantage of diamond rope saw injection moulding heater of the present utility model is: 1, this device is to steel wire rope energising heating, make the inside and outside temperature unanimity of steel wire rope, guaranteed that plastics can well infiltrate in the steel wire rope strand, improved the adhesion strength between a steel wire rope and beading, the plastics; 2, efficiency of heating surface height, saves energy; 3, simultaneously to mold heated, prolonged the plastic cool time, improved the plastics solidification Forming Quality, greatly improve the diamond rope saw quality; 4, control steel wire rope conduction time and energising voltage can reach optimum heating temperature, and can make every section steel wire rope heating-up temperature unanimity, guarantee that the plastics solidification Forming Quality is stable; 5, package unit is simple in structure, and cost is low, easy operating.
