In said structure, during left position power cylinder action, piston rod extends the interior 80mm～100mm of charging aperture of intermediate frequency furnace outward, and during right position power cylinder action, piston rod extends the interior 60mm～80mm of discharging opening of intermediate frequency furnace outward.
The utility model compared with prior art, has following good effect:
1, left position power cylinder and right position power cylinder are craspedodrome mechanism, and alternating movement is controlled easily, and action is quick, and position is controlled, accurate;
2, discharging opening workpiece to be come out of the stove is headed into a segment distance in intermediate frequency furnace burner hearth, can improve workpiece eddy-current heating condition, eliminate the temperature difference of outer face in workpiece to be come out of the stove, be conducive to follow-up forging.
Accompanying drawing explanation
Fig. 1 is that right position power cylinder is static, and the piston rod of left position power cylinder is overhanging, and workpiece to be heated is headed into the structural representation while heating in intermediate frequency furnace burner hearth from charging aperture.
Fig. 2 is that left position power cylinder is static, and the piston rod of right position power cylinder is overhanging, by be positioned at discharging opening heated parts head into the structural representation of intermediate frequency furnace burner hearth.
The specific embodiment
Be described further with reference to the accompanying drawings and in conjunction with implementing the utility model below.
Intermediate frequency furnace discharging opening shown in Fig. 1 device that returns back to top, it comprises pedestal 1, left position power cylinder 2, workpiece 3, intermediate frequency furnace 4, discharging holder 5, right position power cylinder 6 and support 7.Described pedestal 1 is rectangle rack, it is basic part, in pedestal 1 upper surface, fixedly mount along the length direction the intermediate frequency furnace 4 of prone position, the right side of pedestal 1 flushes with the right side of intermediate frequency furnace 4, pedestal 1 right side is fixedly connected with flared support 7, left end at intermediate frequency furnace 4 is fixedly connected with left position power cylinder 2, and the piston rod of left position power cylinder 2 faces the charging aperture 4.1 of intermediate frequency furnace 4.The burner hearth of described intermediate frequency furnace 4 is circle straight tube-like, and the charging aperture 4.1 and the discharging opening 4.2 that are positioned at burner hearth two ends are coaxial, towards right discharging opening 4.2, divide into discharging holder 5.Discharging holder 5 is tilting shape, and when the workpiece 3 heating drops down onto conveyer belt through discharging holder 5 when discharging opening 4.2 is released, conveyer belt is delivered to forging station by the workpiece of heating.In order to guarantee orderly spacing movement, the utility model as shown in Figure 1, the piston rod end of left position power cylinder 2 is faced to the charging aperture 4.1 of intermediate frequency furnace 4, be convenient to after left position power cylinder 2 startups, piston rod stretches into charging aperture 4.1 and will in the burner hearth of workpiece 3 propelling intermediate frequency furnaces 4 to be heated, heat.In addition, the piston rod end of right position power cylinder 6 faces the discharging opening 4.2 of intermediate frequency furnace 4 as shown in Figure 2, its object is also by being positioned at the workpiece 3 that discharging opening 4.2 heated, toward burner hearth, to advance a segment distance after being convenient to right position power cylinder 6 and starting, and makes workpiece two ends Synchronous Heating, does not produce the temperature difference.The present embodiment is manufactured for steel flange forging stock, during left position power cylinder 2 action, piston rod extends the interior 80mm of charging aperture 4.1 of intermediate frequency furnace 4 outward, be that workpiece 3 to be heated gos deep into burner hearth 80mm from the charging aperture 4.1 of intermediate frequency furnace 4, the workpiece 3 newly entering promotes preposition workpiece 3 and moves 80mm toward discharging opening 4.2 directions, be in the workpiece 3 of low order end from discharging opening 4.2 outputs, workpiece 3 afterwards is just in discharging opening 4.2 and waits for next round output.Because being in workpiece 3 right sides of discharging opening 4.2, expose, can not get eddy-current heating and cooling rapidly, and left side is still in burner hearth during output gap, its temperature still can keep heating-up temperature.There is the temperature difference in the workpiece having heated 3 both ends of the surface of therefore, coming out of the stove from discharging opening 4.2.The utility model, in order to overcome discharging opening 4.2 workpiece to be come out of the stove 3 right side cooling problems, is used right power cylinder 6 that the workpiece 3 that is positioned at discharging opening 4.2 is advanced to a segment distance toward burner hearth, and the present embodiment advances 60mm.Because workpiece 3 integral body are all positioned at burner hearth, two end faces is among equal heating environment, and workpiece 3 waits for and coming out of the stove in burner hearth, there is no the forging that is conducive to come out of the stove of the workpiece 3 of the temperature difference, easily realizes high-quality forging, also improves die life simultaneously.
The utility model is responsible for workpiece 3 to push away in burner hearth from left power cylinder 2 and right power cylinder 6, and push-in stroke is depending on workpiece 3 sizes, and the weight of workpiece 3 is greater than 3.5kg and gets large value, otherwise gets the small value, and within the scope of this, value can obtain good forging quality.
