Description

Technical Field

[0001] The invention belongs to the field of heat treatment technology, and in particular relates to a multi-stage tempering forming device and method for a high-toughness transmission steel sheet for automobiles. Background Art

[0002] High-toughness transmission steel sheet for automobiles is one of the important parts in automobile transmissions. Its main function is to change the speed and torque from the engine, and to change the transmission ratio of the output shaft and the input shaft in a fixed or step-by-step manner. This steel sheet ensures the correct meshing between gears by bearing and converting the transmitted force.

[0003] Multi-stage tempering of automobile transmission steel sheets is a heat treatment process used to improve the mechanical properties of steel, especially its hardness, strength and toughness. Tempering is a key step in the heat treatment process and is carried out after quenching. Quenching is heating the steel to a high temperature and then cooling it rapidly to increase its hardness. However, the steel after quenching is often too brittle and lacks toughness, so tempering is needed to eliminate this brittleness.

[0004] During the tempering treatment of automobile transmission steel sheets, due to the different thicknesses of automobile transmission steel sheets, thicker steel sheets may take longer to reach the required tempering temperature, while thinner steel sheets may reach the temperature faster. This may result in the thicker steel sheets not reaching the ideal temperature during the tempering process, while the thinner steel sheets may have been overheated. This makes it difficult to control the tempering forming effect of automobile transmission steel sheets during tempering treatment. Conventional staff also control the temperature control time one by one according to the thickness of the steel sheets, which increases labor costs and has poor overall efficiency.

[0005] In view of this, a multi-stage tempering forming device and method for high-toughness transmission steel sheets for automobiles are proposed. Summary of the invention

[0017] A multi-stage tempering forming method for a high-toughness transmission steel sheet for automobiles comprises the following steps:

[0018] S1. Put the automobile transmission steel sheet after quenching into the heat preservation chamber, manipulate the lead screw 2 to make the internal thread hoop and the linkage seat 3 telescopically displaced, and rely on the linkage frame 2, the linkage frame 1 and the guide frame to make the upper and lower distributed limiting balls relatively displaced, so as to limit the position of the automobile transmission steel sheet;

[0019] S2. When the automobile transmission steel sheet to be tempered is thinner, the guide frame can be displaced toward the boss 2, the friction wheel 1 is at the part with smaller diameter of the boss 1, and the friction wheel 2 is at the part with larger diameter of the boss 2. At this time, the number of turns of the transmission cylinder 1 in the same time is halved; when the automobile transmission steel sheet to be tempered is thicker, the guide frame can be displaced toward the boss 1, the friction wheel 1 is at the part with larger diameter of the boss 1, and the friction wheel 2 is at the part with smaller diameter of the boss 2.

[0021] S4, when the lead screw is operated, the guide seat is displaced, and the position of the diffuser is changed accordingly, so that the heat energy released by the heating thermostat can be more comprehensively directed to the steel plate of the automobile transmission;

[0022] S5, first stage tempering: In steps S1-S4, the quenched guide automobile transmission steel sheet is heated to a relatively low temperature (between 200-400°C) for molding, and kept warm for a period of time, and then cooled; second stage tempering: the heat energy released by the heating thermostat is controlled by the control chamber 2, and the guide automobile transmission steel sheet after the first stage tempering is put into the insulation bin again, and the higher temperature (between 400-600°C) in the insulation bin is used for molding, and then kept warm and cooled again.

[0023] Beneficial effects of the present invention:

[0024] 1. The present invention controls the screw 2 to make the internal thread hoop and the linkage seat 3 telescopically displaced, and relies on the linkage frame 2, the linkage frame 1 and the guide frame to make the upper and lower distributed limiting balls relatively displaced, so as to limit the position of the automobile transmission steel sheet, and ensure that the automobile transmission steel sheet has the same temperature control effect on both sides during tempering treatment;

[0025] 2. The present invention limits the position change of the internal threaded hoop generated by the ball during the telescopic displacement, and links the linkage seat 1, the articulated frame, the linkage seat 2 and the synchronous frame under the action of the displacement of the internal threaded hoop, so that the guide frame can be appropriately displaced according to the telescopic displacement distance of the limiting ball, and under the action of the friction wheel 1, the solid cylinder and the friction wheel 2, the number of circles driven by the boss 1 and the boss 2 can be changed. When the automobile transmission steel sheet is thick, the number of circles of the boss 2 will be more than that under normal conditions, and when the automobile transmission steel sheet is thin, the number of circles of the boss 2 will be slower than that under normal conditions;

[0026] 3. In the present invention, under the progressive transmission between the chain, the second transmission cylinder, the third umbrella-shaped wheel, the fourth umbrella-shaped wheel, the bearing cylinder and the second umbrella-shaped wheel, the first umbrella-shaped wheel is linked to the impeller in the diffuser to run, and the operating frequency of the impeller of the diffuser is the same as that of the first transmission cylinder. At this time, the diffuser can control the amount of heat released by the heating thermostat when it is directed to the automobile transmission steel sheet, so as to better meet the requirements of tempering and forming of automobile transmission steel sheets with different thicknesses, so as to achieve the demand for automatic control of the required temperature;

[0027] 4. The present invention controls the lead screw 1 to displace the guide seat, and the diffuser can change the position of the force acting on the heating thermostat. At this time, the effect of the heating thermostat can be maximized, thereby fully controlling the temperature of the automobile transmission steel sheet.

[0045] Example 1

[0046] Reference Figure 2 and 3 , which is the first embodiment of the present invention, provides a multi-stage tempering and forming device for a high-toughness transmission steel sheet for automobiles, comprising a tempering treatment chamber 100 and two mixing chambers 200;

[0047] The two adjustment bins 200 are arranged at two opposite sides of the tempering bin 100, respectively. The cavity of the tempering bin 100 is assembled with a heat preservation bin 300. A control cavity 101 is formed between the upper and lower inner edges of the tempering bin 100 and the heat preservation bin 300. A control cavity 201 is formed between the adjustment bin 200 and the heat preservation bin 300. A guide channel 1 301 is reserved on the side of the heat preservation bin 300. The inner edge of the heat preservation bin 300 is telescopically provided with a limiting ball 316 with upper and lower relative displacement. The limiting ball 316 is not facing the three sides of the heat preservation bin 300 and can be equipped with a heat insulation board to prevent heat from entering the guide channel 1 301 into the control cavity 2 201. In order to better demonstrate the linkage effect in this design, it is not drawn in the figure. The limiting ball 316 with upper and lower relative displacement can limit the position of the transmission steel sheet.

[0048] The limiting ball 316 is changed from surface contact to point contact relative to conventional clamping. This method allows the steel sheet to be tempered evenly during clamping. At the same time, during the tempering process, the steel sheet can be relatively moved at a certain position, so that the tempering effect can also be uniform.

[0049] Reference Figure 6 , 7, 8 and 9, a linkage frame 1 317 is hinged at the linkage end of the limiting ball 316, and a linkage frame 2 318 is hinged at one end of the linkage frame 1 317 away from the limiting ball 316. A guide frame 503 is provided on the outer cover at the intersection of the limiting ball 316 and the linkage frame 1 317 and the intersection of the linkage frame 1 317 and the linkage frame 2 318. The guide frame 503 is assembled in the control cavity 201, and a positioning seat 319 is assembled in the control cavity 201. The front and back circumferential surfaces of the positioning seat 319 are respectively reserved with a guide channel 4 504 and a guide channel 5 506. A linkage seat 2 327 is reserved in the middle of the positioning seat 319. The linkage seat 2 327 is connected to the guide channel 4 504 and the guide channel 5 506. The linkage seat 327 is connected to the fifth channel 506, the second link seat 327 is hinged with the second lead screw 509, the second lead screw 509 is externally threaded with the internal thread hoop 510, the internal thread hoop 510 is connected to the linkage seat 3 505 through the guide channel 4 504, the linkage frame 2 318 is externally hinged with the linkage seat 3 505, wherein after the second lead screw 509 and the internal thread hoop 510 are threadedly transmitted, under the action of the guide channel 4 504, the linkage seat 3 505 is telescopically displaced along the guide channel 4 504, and under the action of the linkage frame 2 318, the linkage frame 1 317 and the guide frame 503, the limiting ball 316 can telescopically move along the inner edge of the heat preservation bin 300;

[0050] Reference Figure 3 A support frame 500 is assembled on the inner edge of the control chamber 201, and a boss 320 is hinged on the side of the support frame 500. A transmission cylinder 324 is hinged on the inner edge of the control chamber 201. A boss 2 323 which rotates simultaneously with the transmission cylinder 324 is arranged on the linkage end of the transmission cylinder 324. The boss 2 323 is of the same model as the boss 1 320. A guide frame 321 is provided for telescopic displacement in the control chamber 201, and the guide frame 321 is controlled not to flip over during displacement, so as to ensure smooth linkage between the boss 1 320 and the boss 2 323.

[0051] Reference Figure 3 , 6 , 7 and 8, the two extreme positions of the guide frame 321 are hinged with a solid cylinder 322, the middle section of the solid cylinder 322 is hinged with the guide frame 321, and the transmission ends of the upper and lower positions of the solid cylinder 322 are respectively connected with the friction wheel 1 501 and the friction wheel 2 502, the circumference of the friction wheel 1 501 is in contact with the circumference of the boss 1 320, and the circumference of the friction wheel 2 502 is in contact with the circumference of the boss 2 323. When the boss 1 320 is running, the friction wheel 1 501 is linked, the friction wheel 1 501 relies on the solid cylinder 322 to link the friction wheel 2 502, and the friction wheel 2 502 is linked with the boss 2 323;

[0052] Reference Figure 3 and 4A transmission cylinder 2 325 is hinged between the control chamber 201 and the control chamber 1 101. The transmission cylinder 2 325 and the transmission cylinder 1 324 are driven by a sprocket and a chain 513. When the transmission cylinder 1 324 moves in a circle around its axis, it can link the transmission cylinder 2 325 through the chain 513.

[0053] Reference Figure 1 and 2 The front and back of the tempering treatment chamber 100 are milled with door openings 102, and a door stopper 103 is hinged in the door opening 102. The door stopper 103 can be used to place the high-toughness transmission steel sheets for automobiles into the insulation chamber 300 for multi-stage tempering molding. The front of the mixing chamber 200 is assembled with an operator 202;

[0054] Reference Figure 8 and 9 , the inner thread hoop 510 has a linkage seat 1 326 outside that relies on the guide channel 506 for telescopic displacement, a guide cylinder 511 is positioned in the linkage seat 2 327, a guide hoop 512 is guided and telescopic outside the guide cylinder 511, a storage chamber 328 is provided outside the guide hoop 512 at the telescopic position that relies on the guide channel 506, an articulated frame 507 is hinged between the storage chamber 328 and the linkage seat 1 326, and the storage chamber 328 is connected to the guide frame 321 through the synchronous frame 508. When the inner thread hoop 510 is telescopically displaced, the linkage seat 1 326, the articulated frame 507 and the storage chamber 328 drive the guide hoop 512 to telescopically displace in another direction, and when the storage chamber 328 is telescopically displaced, the synchronous frame 508 drives the guide frame 321 to telescopically displace in the control chamber 2 201;

[0055] Reference Figure 3 , 6 As shown in FIG8 , when the guide frame 321 is telescopically displaced, the position of the solid cylinder 322 will also change accordingly, and the positions of the friction wheel 1 501 and the friction wheel 2 502 will also change accordingly. Under the special shapes of the boss 1 320 and the boss 2 323, the solid cylinder 322 can be flipped to a certain extent, and the friction wheel 1 501 is still in contact with the boss 1 320 after flipping, and the friction wheel 2 502 is still in contact with the boss 2 323 after flipping.

[0056] Through this implementation, it can be achieved that: the door stop 103 is opened, and the automobile transmission steel sheet after quenching is placed in the heat preservation chamber 300, so that the automobile transmission steel sheet is placed on the limiting ball 316, and the internal threaded hoop 510 is caused to telescopically displace in the linkage seat 2 327 by controlling the lead screw 2 509, and the linkage seat 3 505 is displaced in the guide channel 4 504, and under the linkage effect of the linkage frame 2 318, the linkage frame 1 317 and the guide frame 503, the limiting balls 316 distributed above and below are relatively displaced, so that the automobile transmission steel sheet can be positionally limited, and the automobile transmission steel sheet can be fully insulated;

[0057] When the automobile transmission steel sheet to be tempered is thinner, the displacement distance of the limiting ball 316 is larger, and the displacement distance of the linkage seat 305 in the guide channel 4 504 is also longer. When the linkage seat 1 326 is displaced, the linkage seat 2 327 can be displaced in a linkage manner. At this time, the guide frame 321 can be displaced toward the boss 2 323. At this time, the friction wheel 1 501 is located at a portion with a smaller diameter of the boss 1 320, and the friction wheel 2 502 is located at a portion with a larger diameter of the boss 2 323. At this time, when the boss 1 320 moves around its axis, the friction wheel 1 501 runs a certain number of turns, and the friction wheel 2 502 can only drive the boss 2 323 to run half a turn with a certain number of turns. At this time, the number of turns that the transmission cylinder 1 324 runs in the same time is halved;

[0058] When the automobile transmission steel sheet to be tempered is thicker, the displacement distance of the limiting ball 316 is smaller, and the displacement distance of the linkage seat 305 in the guide channel 4 504 is also short. When the linkage seat 1 326 is displaced, the linkage seat 2 327 can be displaced in a linkage manner. At this time, the guide frame 321 can be displaced toward the boss 1 320. At this time, the friction wheel 1 501 is located at a portion of the boss 1 320 with a larger diameter, and the friction wheel 2 502 is located at a portion of the boss 2 323 with a smaller diameter. At this time, when the boss 1 320 moves around its axis, the friction wheel 1 501 runs a certain number of circles, and the friction wheel 2 502 can drive the boss 2 323 to run twice the number of circles required for normal thickness with a certain number of circles. At this time, the number of circles that the transmission cylinder 1 324 runs in the same time is increased by two times;

[0059] The transmission cylinder 1 324 relies on the chain 513 to link the transmission cylinder 2 325. The transmission cylinder 2 325 is linked to the bearing cylinder 307 under the action of the umbrella wheel 313 and the umbrella wheel 4 314, and the umbrella wheel 2 311 and the umbrella wheel 1 305 make the impeller in the diffuser 306 run. When the impeller of the diffuser 306 is running, it can guide the heat energy released by the heating thermostat 400 to the two sides of the automobile transmission steel sheet. The transmission cylinder 1 324 makes the working power of the diffuser 306 different when the number of circles it runs is different, so that it can be used for better tempering and forming of automobile transmission steel sheets with different thicknesses.

[0065] Example 3

[0066] Reference Figures 1 to 9 , which is the third embodiment of the present invention, and provides a multi-stage tempering forming method for a high-toughness transmission steel sheet for automobiles;

[0067] S1. Put the automobile transmission steel sheet after quenching into the insulation bin 300, manipulate the lead screw 2 509 to make the internal threaded hoop 510 and the linkage seat 3 505 telescopically displaced, and rely on the linkage frame 2 318, the linkage frame 1 317 and the guide frame 503 to make the upper and lower distributed limiting balls 316 relatively displaced, so as to limit the position of the automobile transmission steel sheet;

[0068] S2. When the automobile transmission steel sheet to be tempered is thin, the guide frame 321 can be displaced toward the boss 2 323, the friction wheel 1 501 is located at the part with smaller diameter of the boss 1 320, and the friction wheel 2 502 is located at the part with larger diameter of the boss 2 323.

[0070] S4, the lead screw 302 is operated, the guide seat 304 is displaced, and the position of the diffuser 306 is changed accordingly, so that the heat energy released by the heating thermostat 400 can be more comprehensively directed to the automobile transmission steel plate;

[0071] S5.
