Summary of the invention
Shearing scissors is adopted to shear in order to solve the moulding mouth of a river in prior art, shear rate is slow, precision is low, cost is high, operator labour intensity is large, easily occurs the problem of industrial accident, the invention provides one and can alleviate operator labour intensity, promote shear precision, improve the moulding large runner high accuracy thermosol shearing jig of shear rate.
In order to solve the problem, the technical solution used in the present invention is:
A kind of moulding large runner high accuracy thermosol shearing jig, comprise pedestal, it is characterized in that: also comprise gas hot shears cutter and source of the gas, pedestal offer for the opening through the moulding mouth of a river, gas hot shears cutter is provided with in the below of pedestal, the moving knife of described gas hot shears cutter front end is positioned at below opening, and described gas hot shears cutter is connected with source of the gas by gas circuit.
Aforesaid a kind of moulding large runner high accuracy thermosol shearing jig, is characterized in that: between gas hot shears cutter and source of the gas, be provided with the flow control valve for regulating gas hot shears cutter moving knife shear rate.
Aforesaid a kind of moulding large runner high accuracy thermosol shearing jig, it is characterized in that: with heat-conducting block on moving knife, described heat-conducting block is connected with electrically heated rod, described electrically heated rod is connected with temperature controller, and described temperature controller is also connected with the temperature sensor for measuring moving knife temperature.
Aforesaid a kind of moulding large runner high accuracy thermosol shearing jig, is characterized in that: in the gas circuit that source of the gas connects, be provided with Foot-controlled switch.
Aforesaid a kind of moulding large runner high accuracy thermosol shearing jig, is characterized in that: the cushion block that can be provided with different-thickness on pedestal, cushion block offers for the opening through the moulding mouth of a river.
Aforesaid a kind of moulding large runner high accuracy thermosol shearing jig, it is characterized in that: on pedestal, be provided with cushion block holder, described cushion block holder is for clamping cushion block.
Aforesaid a kind of moulding large runner high accuracy thermosol shearing jig, it is characterized in that: offer for the rectangular aperture through the moulding mouth of a river on pedestal, cushion block offer for the circular open through the moulding mouth of a river, circular open is positioned at above rectangular aperture, and circular open size is less than the size of rectangular aperture.
The invention has the beneficial effects as follows: shearing jig process velocity of the present invention is fast, and precision is high, and operator labour intensity is little, avoids the generation of security incident, and greatly reduces human cost.The present invention utilizes electrically heated rod and temperature sensor to regulate temperature by temperature controller, when ensureing that the mouth of a river is sheared, moving knife keeps suitable temperature, ftractures when avoiding the mouth of a river to shear.Simultaneously by the shear rate of Flux Valve Control gas hot shears cutter, excessive velocities also can be avoided to cause mouth of a river otch cracking.The present invention simultaneously also can, according to mouth of a river shear height requirement, use suitable cushion block to be arranged on pedestal.
