Description
Technical field
The utility model belongs to special optical glass secondary press technical field, is specifically related to a kind of chalcogenide glass automatic mould press, can be under protective atmosphere complete in batches softening, mold pressing, annealing operation, enhances productivity.
Background technology
In recent years, along with the sizable application in safety supervision and automotive field of the decline of infrared eye price and infrared thermoviewer, chalcogenide glass is progressively good for market, becomes the preferred material of making the thermal imager camera lens.Adopt the traditional technology method, chalcogenide glass needs through section or round as a ball processing after preparation, in order to reach required physical dimension, the method not only efficiency is low, and causes very serious material useless in the course of processing.The method of single thorax mold pressing of adopting at present, that mould and workpiece are completed successively in the fixed position of single burner hearth is softening, mold pressing, annealing process, although solved the useless problem of material, but owing to being the discontinuity mode of operation, production efficiency is still very low, homogeneity of product also can not be guaranteed, and can not adapt to the requirement of batch production.
Summary of the invention
The technical problems to be solved in the utility model is to improve efficiency and the homogeneity of product of chalcogenide glass mold pressing, and a kind of chalcogenide glass automatic mould press is provided.
The technical solution that the utility model adopts is: a kind of chalcogenide glass automatic mould press, comprise burner hearth, and it is characterized in that: described burner hearth is sealed structure, inner employing lagging material longitudinal subdivision is heating zone and cooling area; At the cooling area end, gloves window, rectangle transparent windows and transitional storehouse are installed, in the cooling area outside, circular transparent windows are installed; Burner hearth is arranged on frame; Burner hearth inside is equipped with the rectangular mould guide rail, and the die bottom plate that can fill mould is arranged on the mould guide rail, under the mould guide rail, hot-plate is installed; Upper furnace at the heating zone end is equipped with the pressing mold cylinder near burner one end; Burner hearth both sides and two ends are separately installed with and push away the mould cylinder, push away the mould cylinder and comprise front vertical cylinder, rear vertical push away cylinder, front horizontal cylinder, the rear horizontal cylinder that pushes away of pushing away of pushing away.Under the described effect that pushes away the mould cylinder, the die bottom plate that mould is housed can slide along the rectangular mould rail circulation, and workpiece is seated in mould, after softening, mold pressing, annealing operation, through the gloves window outside transitional storehouse takes out stove.
The burner below of the burner hearth described in the utility model technical solution is equipped with intake valve, and stove tail top is equipped with vent valve, and furnace side is equipped with pressure display table.
Compared with prior art, taked the burner hearth of sealed structure due to the utility model, also can fill shielding gas in furnace chamber, can prevent effectively that workpiece from the die mould process, oxidation occurring.Due to the periodic cycle press moulding mode that adopts, can significantly enhance productivity, ensure product consistency, be particularly suitable for the batch mold pressing processing of chalcogenide glass.
The utility model is mainly used in the chalcogenide glass automatic mould press.

Description of reference numerals: support 1, burner hearth 2, mould guide rail 3, mold pressing cylinder 4, front vertical push cylinder 5, rear vertical push cylinder 6, front horizontal push cylinder 7, rear horizontal push cylinder 8, hot-plate 9, die bottom plate 10, mould 11, lagging material 12, transitional storehouse 13, circular transparent windows 14, intake valve 15, vent valve 16, tensimeter 17, gloves window 18, square transparent windows 19.
Embodiment
As shown in Figure 1 to Figure 3, the utility model comprises frame 1 and burner hearth 2, burner hearth 2 is arranged on frame 1, burner hearth 2 inside are equipped with rectangular mould guide rail 3, burner hearth 2 tops are equipped with pressing mold cylinder 4 near burner one end, before and after burner hearth and both sides are equipped with and push away the mould cylinder, comprise front vertical cylinder 5, rear vertical push away cylinder 6, front horizontal cylinder 7, the rear horizontal cylinder 8 that pushes away of pushing away of pushing away.
Mould guide rail in heating zone and a part of cooling area is equipped with hot-plate 93 times, under the described effect that pushes away the mould cylinder, the die bottom plate 10 that mould 11 is housed can slide along 3 circulations of rectangular mould guide rail, workpiece is seated in mould, after softening, mold pressing, annealing operation, through gloves window 18, from transitional storehouse 13, take out outside stove.
Principle of work of the present utility model is as follows:
Softening process: the heating power of controlling each section hot-plate 9 in burner hearth 2 heating zones, make temperature progressively rise to the required technological temperature of chalcogenide glass die mould, inside fills in harness mould 11 and is arranged on die bottom plate 10, under the effect that pushes away the mould cylinder, die bottom plate 10, wherein frontly vertical push away cylinder 5 and vertically pushes away cylinder 6 and move simultaneously afterwards together along rectangular mould guide rail 3 loopy movings with mould 11, for vertically pushing away mould, frontly horizontally push away cylinder 7 and the rear horizontal cylinder 8 that pushes away moves simultaneously, be used for laterally pushing away mould.Due to conduction of heat, workpiece temperature also rises to predetermined technological temperature at the heating zone end, and, because burner hearth 2 inside are filled with shielding gas, can avoid workpiece that oxidation occurs on high temperature.Controlling System, according to the numerical value that pressure display table 17 transmits, is controlled the action of intake valve 15 and vent valve 16 in good time, and the pressure of shielding gas in stove is maintained in the pressure-fired scope of setting.
Mold process: when the mould 11 that workpiece is housed is pushing away under the effect of mould cylinder, while pressing the setting cycle loopy moving to mold pressing cylinder 4 below, mold pressing cylinder 4 descends and the compaction mold upper die head, and down force pressure is adjustable.Mold pressing cylinder 4 return that rises after pressure maintaining period and zero-pressure process, it is constant that cylinder keeps the down force pressure of adjusting in advance in pressure maintaining period, be convenient to Workpiece shaping, the cylinder down force pressure is zero in the zero-pressure process, workpiece only bears the formed pressure of deadweight of cylinder depression bar and upper mould part, be convenient to the workpiece volume with temperature change free-extension.
Annealing process: after workpiece is completed mold pressing, in company with mould 11, together under the effect that pushes away the mould cylinder, from the heating zone end, be transferred to cooling area top, enter annealing operation.The part of the forward end of cooling area is equipped with some hot-plates 9, by the annealing temperature curve requirement, controls each temperature of heating plate, and workpiece enters from the cooling area rear end and carries out naturally cooling successively after this heating region, complete annealing process.Annealed workpiece, from burner hearth 2 afterbodys,, is carried out the demoulding and processes and take out by 18 operations of gloves window by artificial from mould 11.Mold pressing is complete and treat the workpiece of mold pressing and standby mould all from transitional storehouse 13 turnover burner hearths 2, avoids operating process peripheral air to enter and affects the mold pressing quality.In the equipment work process, operator can, by circular transparent windows 14 and the square transparent windows 19 of burner hearth 2 sidepieces installations, observe and the interior operation conditions of monitoring stove.
