Abstract
The utility model relates to a programmable aluminium braze air furnace, which belongs to the technical field of brazing. The utility model is composed of a control system 1, a movable furnace body 3, and a workpiece carrier 7. The control system 1 is mainly composed of a programmable temperature controller, a temperature recorder, a silicon-controlled switch and various feature buttons. The utility model is characterized in that the movable furnace body 3 is in shape of a barrel; the movable furnace body is externally wound by resistance heating elements; then the movable furnace body is coated by heat insulating materials to be crossly arranged on a support frame of a whole rolling wheel. The workpiece carrier 7 is in a fixed style. The utility model realizes automatic control of brazing technics procedure.
Description
The utility model belongs to the soldering tech field.
At present, for the soldering of aluminium and aluminium alloy, can adopt salt bath brazing, vacuum brazing, micro-brazing flux to add methods such as nitrogen-protective soldering, air furnace brazing.The applying unit many concerning those product varietys, that quantity is few, first three kind equipment not only costs an arm and a leg, complex technical process, and also the production cycle is long, and production efficiency is low; And brazed aluminum alloy in the air furnace, not only equipment manufacturing cost is low, and technology is simple, and uses also very convenient.Mostly aluminium alloy air furnace brazing in the past is to carry out at original heat-treatment furnace or in the stove after reequiping, original temperature control condition makes the temperature control ratio of soldering difficult, how with the artificial visually examine, operation by rule of thumb, cause brazing quality stable inadequately, influenced people carrying out the correct understanding of aluminium soldering in the air furnace.
The purpose of this utility model is to rely on the range estimation operation in the operational procedure when overcoming in the past in air furnace brazed aluminum alloy, causes the unsettled drawback of brazing quality easily, realizes the parameter control of aluminium soldering operating process in the air furnace.
The purpose of this utility model is achieved in that the aluminium soldering air furnace of being made up of control system, movable body of heater and work supporting block three parts able to programme, and its control system mainly is made up of Programmable Temperature controller, moisture recorder, reverse-blocking tetrode thyristor and various feature button.This control system can be provided with process, control furnace chamber heating power, and braking body of heater advance and retreat, and write down furnace chamber temperature and workpiece actual temperature respectively; Movable body of heater is the garden tube that is rolled by steel plate, outward around resistance heating element, coats the heating furnace chamber of forming with insulation material again, be disposed across on the support of band roller, flexible by motor-driven axostylus axostyle, the reach that realizes body of heater with retreat; Work supporting block is fixed, makes workpiece be in a stable state all the time in the heating and cooling process.In overall operation, as long as brazing member is placed on the work supporting block, the technological parameter that is carried out is by certain rule input programmable device, movable body of heater can give heat, body of heater reach (shove charge), workpiece heating, soldering insulation, body of heater is stepped back the overall process of (coming out of the stove), and moisture recorder can write down the heating curves of furnace chamber temperature and workpiece respectively.
Advantage of the present utility model is: can finish body of heater automatically by the process of setting and give the overall process that heat, workpiece are advanced stove, heating, soldering insulation, come out of the stove, avoided high temperature shove charge in the past, observe the soldering situation with eyes and forbidden because of the temperature and time grasp easily, cause influence brazing quality.
Fig. 1 is an overall structure schematic diagram of the present utility model;
Introduce structure of the present utility model and operation principle in detail below in conjunction with accompanying drawing:
Fig. 1 is an operation principle block diagram of the present utility model.
Fig. 2 is an overall structure schematic diagram of the present utility model;
Fig. 3 is the shutoff stroke figure of movable fire door;
Aluminium soldering air furnace able to programme is made up of control system 1, movable body of heater 3 and work supporting block 7 three parts, as shown in Figure 2.Control system 1 can be provided with process, control furnace chamber heating power, and the braking body of heater is advanced and retreat and is write down furnace chamber temperature and workpiece actual temperature respectively.As shown in Figure 1, with required technological parameter input Programmable Temperature controller, reverse-blocking tetrode thyristor is regulated under the driving of Programmable Temperature controller and is supplied with the body of heater heat energy, and the signal that thermocouple returns makes furnace temperature reach predetermined temperature, and the furnace chamber temperature is by the moisture recorder record.Automatically during operation, provide instruction, make the motor forward and backward, drive axostylus axostyle and stretch out and return, realize the automatic reach of body of heater and retreat, finish the overall process of soldering at the standard point of regulation; In the time of manually, by the advance and retreat of knob control body of heater.XWD type moisture recorder can write down the temperature rise parameter of furnace chamber temperature and soldering work piece respectively by change-over switch, very helps soldering processes analysis and parameter adjustment.
As shown in Figure 2, the furnace chamber accumbency of garden barrel shape is installed on the framework that has roller, by stretching of driver axostylus axostyle 9, finishes the reach of body of heater on the ground rail and retreats, realize soldered component turnover stove process, driver axostylus axostyle 9 flexible can have manually and programmable device is controlled dual mode automatically.The furnace chamber of garden barrel shape forms around resistance heating element outside being rolled by steel plate.Be contained in movable bell 4 and body of heater interlock on the body of heater, by rope and machinery compel system mechanism the body of heater reach with retreat in finish the opening and closing of movable fire door in the prescribed stroke, work supporting block 7, fixedly bell 5 and workpiece 8 maintain static in whole process.Furnace chamber thermocouple 2 plays a part to measure and control furnace chamber temperature, and workpiece thermocouple 6 is used for measuring and controlling the temperature rise situation of workpiece.
The opening and closing process of movable bell 4 as shown in Figure 3, when body of heater remained static A, movable bell was closed; When body of heater when particle a moves to a ', movable bell is all opened and is presented part and advance the stove process, up to a " body of heater stops automatically, fixedly bell 5 seals fire doors, carries out soldering heating and insulating process.Otherwise body of heater returns to A, and workpiece is all come out of the stove, and when movable bell is closed to a position, closes end, has guaranteed that body of heater gives when hot the uniformity of temperature in the stove, for next soldering is got ready.
This stove has adopted to be treated that the pricker part is placed on the carriage and maintains static, and finishes the scheme of turnover stove overall process, the unstability in the time of can avoiding the stove of workpiece turnover in the past by the body of heater motion.Pyrometer fire-end is contact workpiece or at hot junction dress simulating piece directly, can more accurate measuring workpieces variation of temperature situation, and note with the form of curve.
