Abstract
The utility model discloses a tunnel type heat treatment device, comprising a furnace, a hearth, a transport network belt, and a driving device. The inner wall of the hearth is arranged with heating elements, and the furnace is inserted inside the hearth. A part of the furnace projects from one end of the hearth, and the outer wall of the protruding part of the furnace is provided with a cooling water jacket. The transport network belt passes through the inside of the furnace and is driven by a driving device. The driving device is one driving device which can conduct the bidirectional movement. When the transport network belt moves positive direction, the transport network belt can conduct the air quenching; when the transport network belt moves reverse direction, the transport network belt can be used for the oil cooling or the water hardening.
Description
The utility model relates to a kind of tunnel type annealing device.
Tunnel type heat-treatment furnace commonly used has one to transmit guipure in the flue in the burner hearth, workpiece is placed on the guipure, sends into from one, after being heated in stove, comes out from the other end, puts into oil quenching again.Generally be connected with inertia or restitutive protection's gas in the flue.With the stove of air quenching, for example be used for the stove that Stainless Steel quenches, then also in succession one section and use water-cooled flue at the port of export of burner hearth, workpiece is just come out of the stove after cooling off in this section flue.Therefore, the heat-treatment furnace that is used for air quenching can not be used for oil cooling and but quench, and is used for heat-treatment furnace that oil cooling but quenches and then can not be used for carrying out air quenching.
The purpose of this utility model is to propose a kind ofly can be used for air quenching and can be used for the heat-treatment furnace that oil or water cooling are quenched again.
This heat-treatment furnace comprises flue, burner hearth, transmission guipure and a transmission device, and heating element heater is housed on the inboard wall of burner hearth, and flue is inserted in the burner hearth, and the part of flue is stretched out from an end of burner hearth.One cooling jacket is arranged on the outer wall of flue extension.Transmit guipure and in flue, pass, drive by transmission device, but this transmission device is the transmission device of a bidirectional-movement.
During the running of the transmission device forward of this heat-treatment furnace, transmit the guipure positive movement, workpiece is put on guipure, after the heating, enters in the water-cooled flue, by the cold air Cooling Quenching in the flue in an end of no-cooling-water cover enters flue the burner hearth.When the reverse running of transmission device, transmit the guipure reverse movement, workpiece enters in the flue from the end that cooling jacket is arranged, and when arriving burner hearth, is heated, and comes out it to be dropped into the oil or in the water from the other end then and quenches.Like this, this heat-treatment furnace both can be used for dry quenching, also can be used to carry out oil cooling or water hardening.
Accompanying drawing 1 is the structure cut-away view of this heating furnace;
Accompanying drawing 2 is two-way diagrams of gears;
Accompanying drawing 3 is structure charts of another kind of two-way transmission device;
Accompanying drawing 4 is heating element heater layout drawings of inboard wall of burner hearth;
Accompanying drawing 5 is heating curves of this heat-treatment furnace.
As shown in Figure 1, (3) are flue among the figure, are inserted in the burner hearth (2), flue has cooling jacket (7) outside burner hearth one end extension, transmission guipure (9) passes in flue (3), is driven by bidirectional-movement transmission device (10), makes forward or reverse movement.(1) is heating element heater among the figure, and (4) are expansion joint, and (5) are the protective gas import, and (6) are coolant outlet, and (8) are the protective gas port, and (11) are cooling water inlet.
As shown in Figure 2, this bidirectional-movement transmission device can be a live roller (13) and two contact rollers (12), (14), and two contact rollers are pressed in guipure (9) on the live roller (13) from two directions of motion respectively.Live roller changes the rotation direction of motor by a driven by motor, just can change the direction of motion of guipure, uses two contact rollers can guarantee that guipure can both fit tightly with live roller when doing the both direction motion, to produce enough frictional force.
As shown in Figure 3, the bidirectional-movement transmission device also can be two drives (15), (16) at guipure two ends, each free driven by motor of this two drive, the direction of rotation of two motors is opposite, the motor of drive (15) rotates counterclockwise drive (15), and the motor of drive (16) clockwise rotates drive (16).During work, only drive wherein motor.Start the motor of drive (16), guipure is promptly made positive movement, and starts the motor of drive (15), and guipure is promptly made reverse movement.If the rotating shaft of above-mentioned motor links to each other with drive by behind the decelerator again, then can between decelerator and drive, adorn a clutch, when this motor is not worked, can be with throw-out-of clutch, so that change the direction of motion of guipure.
As shown in Figure 4, for the heating properties that makes this heat-treatment furnace meets air cooling and oily, water-cooled requirement more, in burner hearth, can make one group of heating element heater (17) of control separately from a cooling jacket end far away.When the cooling of guipure positive movement, air, this group heating element heater is not opened, and makes the temperature-rise period of workpiece meet the requirement of air cooling, and when guipure counter motion, oil cooling or water-cooled, this group heating element heater work when workpiece is come out of the stove, is in the desired maximum temperature of quenching.(18), (19), (20) are other several groups of heating element heaters among the figure, and (21), (22), (23) are insulating.
The heating furnace of this spline structure, its temperature curve as shown in Figure 5, the heating curves when (24) are the cooling of guipure positive movement, air among the figure, (25) are the guipure reverse movement, heating curves when oil cooling or water-cooled, this moment, the temperature of workpiece was that right-to-left is by curvilinear motion.These two curves meet the requirement of Technology for Heating Processing fully.
Claims (3)
1, a kind of tunnel type annealing device, comprise flue, burner hearth, transmission guipure and a transmission device, heating element heater is housed on the inboard wall of burner hearth, flue is inserted in the burner hearth, the part of flue is stretched out from an end of burner hearth, and a cooling jacket is arranged on the outer wall of flue extension, transmits guipure and passes in flue, drive by transmission device, but it is characterized in that described transmission device is the device of the transmission of a bidirectional-movement.
2, annealing device as claimed in claim 1, the transmission device that it is characterized in that described bidirectional-movement are a live roller and two contact rollers, and described two contact rollers are respectively from two directions of motion guipure to be pressed on the live roller.
