The utility model adopts mechanical pressurizing and hydraulic sensing; pressure value is controlled by a pressure gauge; pressing time is controlled by a time relay to improve the efficiency of pressing a character matrix plate, an accumulating ink pad, and a stamp mark; the quality of product is ensured.

Description

Hydraulic sensing fully automatic thermocompressor

The utility model relates to machine driving hydraulic sensing hot-press arrangement, especially hydraulic sensing full-automatic heating press in making the atom print process.

In the manufacturing process of atom print, the compacting of character matrix plate, ink collecting pad, steel seal is particularly important, and it requires the temperature of hot press, pressure accurately to stablize.At present, the hot press of selling on the market has two kinds, and a kind of is to adopt screw mandrel or jack pressurization, because it does not have Pressure gauge to show pressure value, so can only judge with feel or experience, often easily build-up of pressure is inaccurate, causes the quality of product to be affected; Another kind is to adopt single hydraulic pressurization, its a whole set of hydraulic system requires the machining accuracy height, difficulty is big, because it is in pressurization, when driving pressure, piston stroke is big, so leakage of oil easy to wear, the build-up of pressure instability, cause ftercompction several in the process period, increased workload, and directly influenced the quality of product.

The purpose of this utility model promptly produces thus, and a kind of hydraulic sensing full-automatic heating press is provided, and it adopts machinery pressurization, hydraulic sensing, thereby makes the temperature of hot press, pressure stability reliable, has guaranteed the quality of product.

For achieving the above object, the utility model is achieved through the following technical solutions.It mainly is made of last heating plate, following heating plate, hydrostatic sensor, ejector sleeve, T type nut, T type screw rod, worm gear, worm screw, be provided with the oil-containing copper sheathing in the worm gear lower end, T type screw rod is fixed in the oil-containing copper sheathing by worm gear, T type nut and the supporting use of T type screw rod, at T type nut overcoat ejector sleeve is arranged, hydrostatic sensor is placed on the ejector sleeve upper end by pallet.Have on it and be used for the hydraulic pressure hole that connects with Pressure gauge, Pressure gauge control also shows pressure value, and last heating plate is fixed on four root posts, and following heating plate is arranged on above the hydrostatic sensor, moves up and down with hydrostatic sensor.Controlled by the time relay its pressing time.

The utility model is reasonable in design, adopt machinery pressurization, hydraulic sensing, by Pressure gauge controlled pressure numerical value, adopt the time relay control pressing time, thereby compare with existing heater, overcome existing heater temperature, the not wield shortcoming of pressure, improved widely and suppressed the efficient of character matrix plate, ink collecting pad, steel seal, and guaranteed product quality.

The utility model accompanying drawing is a structural representation.

In the accompanying drawing, 1 pick-up piston, 2 sensor sealed pictures, 3 hydraulic pressure holes, 4 bakelite heat insulating mattress, 5 sensor cylinder barrels, 6 sensor pallets, 7 feather keys, 8 ejector sleeves, 9T type nut, 10T type screw rod, 11 are set upright tube, 12 worm gears, 13 gearboxes, 14 pressure bearings, 15 oil-containing copper sheathings, 16 worm screws.

In conjunction with the accompanying drawings, it is as follows to provide the utility model accompanying drawing:

As shown in the figure, the utility model is mainly by hydrostatic sensor, worm gear, worm screw, T type nut, T type screw rod, ejector sleeve constitutes, worm gear 12, worm screw 16 all is arranged in the gearbox 13, be provided with an oil-containing copper sheathing below the worm gear 12, T type screw rod 10 is fixed wherein, also be provided with a pressure bearing 14 on the oil-containing copper sheathing, purpose is that T type screw rod is rotated flexibly, supporting on the T type screw rod of the upper end of worm screw have a T type nut 9, ejector sleeve 8 is fixed on T type nut outside, set upright the outer end that tube 11 is arranged on ejector sleeve, it is fixedlyed connected with gearbox, effect is can help motion greatly reposefully on it when ejector sleeve when moving, 1 feather key 7 is arranged on the fixed axis, effect also is that the guiding ejector sleeve steadily moves up and down, pallet 6 is placed on sets upright the tube upper end, its bottom can be put and is convex, hydrostatic sensor is placed on the pallet, it is by piston 1, sealing ring 2, hydraulic pressure hole 3, sensor cylinder barrel 5 constitutes, owing to adopt hydraulic sensing, be connected with Pressure gauge by hydraulic pressure hole 3, controlled pressure numerical value makes the not enough 1mm of piston stroke, thereby has increased the service life of sealing ring 2, adopt pressing time the time relay to control automatically, during to the fixed time, the motor automatic reverse winding is driven and is pressed, and the upper ends of hydrostatic sensor has bakelite heat insulation 4, it on it heating plate, it is immovable that last heating plate is fixed on four root posts, and following heating plate is arranged on the upper end of bakelite heat insulating mattress 4, and it moves up and down with hydrostatic sensor, on, the temperature of following heating plate is by the thermocouple that is placed in the heating plate, thermometer control, very accurate.The course of work of the present utility model is as follows: starter motor drives worm screw, worm gear, the rotation of T type screw rod, T type nut holds under the effect of T type screw rod and rises or descending motion, promoting ejector sleeve rises or descends, thereby following heating plate on the hydrostatic sensor and last heating plate are done to hold out against or disengaging movement, the numerical value of its heating plate pressure is shown and control that by Pressure gauge the time relay is used to control pressed temperature.
