The processing technology of the step-by-step forming equipment for the energy-saving hot forming steel parts comprises the following steps:
step one, feeding:
positioning a steel part 13 to be formed through a blank positioner 12 and placing the steel part on a feeding workbench 11; after a processing production line of the step-by-step forming equipment is started, a feeding and discharging manipulator 21 behind a feeding device sends the steel part 13 to be formed to a primary composite heating part transmission device A31;
step two, primary heating:
the primary composite heating part transmission device A31 drives the steel part 13 to be formed to move, the steel part is heated and heated by the primary composite heating rapid heating equipment 32, then the steel part is conveyed into the primary composite heating low-speed heating equipment 33 to be heated at a low speed, and the primary composite heating part transmission device B34 drives the steel part 13 to be formed to move backwards at a constant speed; when the steel type part 13 to be formed is a coated hot formed steel type part or a non-coated hot formed steel type part, a heating process thereof is separately described as follows:
1) the steel part 13 to be formed is a hot forming steel part with a coating; firstly, rapidly heating the hot forming steel part with the coating to 450 ℃ by a one-time composite heating rapid heating device 32, wherein the heating rate is more than 30 ℃/s; conveying the hot forming steel part with the coating into a primary composite heating low-speed heating device 33 for low-speed heating, wherein the temperature of the hot forming steel part with the coating is increased from 450 ℃ to 700 ℃ at a heating rate of 1.5-6 ℃/s, and the heating rate is limited because the coating and the steel part are further reacted, the optimal temperature range for thickening the alloying layer is 450-700 ℃, and the reaction combination process needs a certain time to be completed;
the temperature of the hot forming steel part with the coating is raised to 700 ℃ through a heating process, the temperature distribution is uniform, and the coating and the surface of the steel part form an alloying layer to be further thickened.
2) The steel part 13 to be formed is an uncoated hot forming steel part; firstly, rapidly heating a non-coating hot forming steel part to 450 ℃ by a one-time composite heating rapid heating device 32, wherein the heating rate is more than 30 ℃/s; conveying the uncoated hot forming steel part into a primary composite heating low-speed temperature rising device 33, conveying the uncoated hot forming steel part backwards along with a primary composite heating part conveying device B34, heating and raising the temperature in the conveying process, and finally heating to 700 ℃;
the temperature of the uncoated hot forming steel part is raised to 700 ℃ through one heating process, and the temperature distribution is uniform.
The primary heating mode is a composite heating mode, namely a heating mode combining rapid heating and low-speed heating; the rapid heating part comprises induction heating, electric heating and the like; the low-speed heating can adopt the modes of electric heating, gas heating and the like, and the structure of the low-speed heating furnace can adopt a box furnace or a roller bottom wheel and the like.
Step three, one-step forming:
the upper press table outside the upper thermoforming mold 71 is in an open state, so that the upper thermoforming mold 71 is also in an open state; the feeding and discharging manipulator behind the primary heating device takes the heated steel part 13 to be formed out of the primary composite heating low-speed heating device 33 and puts the heated steel part into the lower die 72 of the hot forming die; after the steel part 13 to be formed is placed into the lower thermoforming mold 72, the upper workbench of the press moves downwards to drive the upper thermoforming mold 71 to move downwards, and finally the upper thermoforming mold 71 and the lower thermoforming mold 72 are closed to finish the primary forming of the steel part 13 to be formed so as to obtain a primary formed part; this process is completed within 10 seconds from the feeding to the completion of one forming.
In the process of primary forming, resistance wires in the upper die heating hearth 75 and the lower die heating hearth 76 respectively heat the upper die insert A73 and the lower die insert A74, so that the temperatures of the upper die insert A73 and the lower die insert A74 are kept at 450-600 ℃, and the temperature of the primary forming die is set at 450-600 ℃.
Whether the steel part 13 to be formed is a coated hot forming steel part or a non-coated hot forming steel part, the temperature for one-time forming in the hot forming die is 450-600 ℃, and the reason for setting the one-time forming temperature is as follows:
1) the existing state of the coating in the temperature interval is non-liquid state, and the coating cannot be damaged in the forming process;
2) the deformation resistance of the hot forming steel plate in the temperature range is small;
3) the hot forming steel plate in the temperature range has better plasticity;
4) the temperature of the once-formed part is still between 450 ℃ and 600 ℃ after forming, and the temperature is continuously increased on the basis of the temperature in the subsequent secondary heating process without increasing the temperature from the room temperature state, thereby achieving the purpose of energy conservation.
The one-step forming process achieves two purposes: firstly, ensuring that a steel part 13 to be formed deforms to realize the shape presentation of a product, namely a one-step forming part; and secondly, the temperature of the steel part 13 to be formed is always kept above 450 ℃ in the process of converting into a one-time forming piece.
Step four, secondary heating:
the upper workbench of the press on the outer side of the upper die 71 of the hot forming die moves upwards to drive the upper die 71 of the hot forming die to move upwards and separate from the lower die 72 of the hot forming die; the feeding and discharging manipulator at the rear of the primary forming device takes out the primary forming piece from the lower die 72 of the thermoforming die and sends the primary forming piece into the secondary heating furnace 51, the primary forming piece is rapidly heated in the secondary heating furnace 51 for the second time, and finally the temperature is heated to 830-879 ℃, the heating rate is 10-20 ℃/s, and the setting is carried out according to the production line beat; after the primary forming piece finishes the set temperature rise, preserving the heat for 120 s;
the secondary heating process is intended to achieve two purposes: firstly, rapidly raising the temperature of a primary forming part to a set temperature of 830-879 ℃; and secondly, ensuring that the internal and external temperature of the once-formed part is uniformly distributed.
The secondary heating furnace 51 may be a box furnace, a rotary heating furnace, or the like, and the heating method may be an electric heating method, a gas heating method, or the like.
Step five, shaping and quenching:
the upper workbench of the press on the outer side of the upper die 81 of the shaping and quenching die is in an open state, so that the upper die 81 of the shaping and quenching die is also in an open state; after the primary formed part is heated, the feeding and discharging manipulator behind the secondary heating furnace 51 takes the primary formed part out of the secondary heating furnace 51 and puts the primary formed part into the lower shaping and quenching die 82; after the primary formed piece is placed in, the upper workbench of the press moves downwards to drive the upper shaping and quenching die 81 to move downwards, and finally, the upper shaping and quenching die 81 and the lower shaping and quenching die 82 are closed and pressure maintained for 10s to finish shaping and quenching of the primary formed piece; this process is completed within 5 seconds from the feeding to the closing of the mold.
In the shaping quenching process, cooling water is introduced into cooling pipelines in the upper die insert B83 and the lower die insert B84 to cool the primary formed part, the flow rate and the flow speed of the cooling water in the upper die insert B83 and the lower die insert B84 are used for ensuring that the cooling rate of the finally formed steel part is more than 60 ℃/s, and at the cooling rate, austenite formed at high temperature is finally converted into martensite or martensite-bainite structure with high strength.
The shaping and quenching process achieves two purposes: firstly, correcting deformation generated in the secondary heating process of a primary forming piece to realize accurate presentation of the shape of a final product; and secondly, finishing quenching of the final formed part.
The molded surface design of the primary forming thermoforming mold ensures that the shape of the primary forming piece is completely consistent with the shape of a final product; parts can slightly deform in the secondary heating process, and the shaping quenching die can eliminate the slight deformation in the secondary heating process, and the method has the following three explanations: firstly, because the deformation amount is small in the forming process, the forming force is small, the tonnage of the required press is small, the 500T press can meet the requirement, and the production energy consumption is low; secondly, as the shape of the primary formed part is close to that of the final product, the idle stroke of the press is increased in the forming process, the loading stroke is greatly reduced (the thickness of the part material is 2-3 times), and the speed of the press in idle time is far greater than that of the press in loading time, so that the closing time of the press is greatly reduced, and the shaping and quenching processes can be completed from the material taking to the mold closing within 5 s; and thirdly, the upper die insert B83 and the lower die insert B84 in the shaping and quenching die almost simultaneously contact with the steel part, and the cooling speeds of the steel part are close, so that the final performances are close to the same.
Step six, blanking:
the upper workbench of the press on the outer side of the upper die 81 of the shaping and quenching die moves upwards to drive the upper die 81 of the shaping and quenching die to move upwards and separate from the lower die 82 of the shaping and quenching die; and the finally formed steel parts are taken out from the lower die 82 of the shaping and quenching die and are sent to the blanking conveyor belt 61 by the feeding and discharging manipulator behind the shaping and quenching device, so that the transmission of the hot formed steel parts is completed.
Taking an annual production capacity of 100 ten thousand times of stroke production line as an example, the energy-saving situation is as follows:
the power of a heating furnace of the traditional thermal forming production line is about 1500kW, the power of a 1200T press is 500kW, and the total power for completing the thermal forming is about 2000 kW; adopt the utility model discloses a technology, once heating power includes quick heating device 600kW and box furnace heating 350kW, 950kW in total. A set of 800T press machine 350kW, a set of 500T press machine 100kW, total 450kW and secondary heating furnace 200 kW; the total heating and forming power is 1600 kW. Compared with the traditional hot forming production line, nitrogen making equipment, cooling water equipment and the like are consistent, so that the total energy is saved by about 20%.
Taking the annual production capacity of 100 ten thousand times of stroke production line as an example, the space is saved:
three processes of traditional thermoforming production line material loading, heating, shaping take up an area of length about 65 meters (loading attachment 8 meters, heating furnace 40 meters, press 10 meters, unloading conveyer belt 7 meters), adopt the utility model discloses technology, the total length of production line is about 50 meters (loading attachment 8 meters, quick heating part 3 meters among the heating device, box furnace heating part 12 meters, the press 10 meters that once takes shape, 5 meters of secondary heating device, 5 meters of secondary forming press, unloading 7 meters, practice thrift the factory building space more than 20%.
In conclusion, the energy-saving step-by-step forming process for the hot forming steel parts with the coatings mainly comprises the steps of primary heating, primary forming, secondary heating and shaping and quenching; the significance of one-time heating is to ensure that the temperature of the hot forming steel part rises to 700 ℃ and the temperature is uniformly distributed, and simultaneously, the coating and the alloying layer on the surface of the hot forming steel part are further thickened in the temperature rising process.
