Description

Technical Field

[0001] The invention relates to the technical field of presses, in particular to a multi-station gear hot die forging press. Background Art

[0002] In the field of mechanical manufacturing, hot die forging is a process that heats metal billets and then forges them into shape, resulting in workpieces with excellent mechanical properties. Multi-station hot die forging presses enable continuous processing of multiple steps, significantly improving efficiency. Presses with three stations for heating, pre-forging, and final forging are widely used. Gears, as key transmission components, require press processing to achieve precise tooth shape, dimensions, and mechanical properties to meet transmission accuracy and load requirements.

[0040] Specifically, such as Figure 2 、 Figure 3 and Figure 4 As shown, the dust collection structure 6 includes a dust collection box 601 fixedly connected to the press body 1 and a deflector 602 fixedly connected to the dust collection box 601. A filter screen 603 is installed on the dust collection box 601. A vacuum pump 604 is installed on the dust collection box 601. The air intake of the vacuum pump 604 is connected to the top of the filter screen 603 through a pipe. The vacuum pump 604 cooperates with the filter screen 603 to suck away a large amount of waste slag, thereby preventing the waste slag from accumulating in the working area and affecting the forging accuracy. The dust collecting box 601 is provided with a collecting box 605, and a sealing plate 606 is slidably connected to the air guide cover 602. A second driving member 607 is installed on the air guide cover 602, and the sealing plate 606 is driven by the second driving member 607. A fan 608 is installed in the dust collecting box 601.

[0041] Specifically, such as Figure 1、 Figure 2 、 Figure 12 and Figure 13 As shown, the collection structure 7 includes a collection vehicle 701 detachably connected to the press body 1 and a lifting plate 702 slidably connected to the collection vehicle 701. The collection vehicle 701 is fixedly connected to a connecting block 703, and the connecting block 703 is slidably connected to the press body 1. A third driving member 705 is installed on the press body 1, and a fixed block 706 is installed at the driving end of the third driving member 705. A lifting rod 704 is fixedly connected to the lifting plate 702, and the lifting rod 704 is slidably connected to the fixed block 706. When collecting, the third driving member 705 (preferably a liquid) is activated. The lifting rod 704 is installed on the fixed block 706, so the lifting rod 704 drives the lifting plate 702 to rise synchronously, and the height of the gear workpiece is reduced by increasing the height of the lifting plate 702 to prevent the gear workpieces from colliding with each other and reducing the quality due to the falling height being too high. A stopper 707 is slidably connected to the fixed block 706, and a guide rod 708 is fixedly connected to the fixed block 706. A pull plate 710 is fixedly connected to the stopper 707, and a second spring 709 is fixedly connected between the pull plate 710 and the guide rod 708.

[0042] When the present invention is in use, the press body 1 starts the fourth driving member 8 (preferably a hydraulic rod) to drive the upper die seat to move and apply pressure to the lower die blank to complete the forging. Since the dies on the three mounting plates 203 correspond to heating, pre-forging, final forging and other processes respectively, under the coordination of the control system, the conveying device uses the servo motor and the ball screw pair to accurately control the blank clamping mechanism based on the opening and closing status of the station die, the blank position and other information fed back by the sensor, and conveys the workpiece from one station to the next station in turn according to the set trajectory and speed, thereby realizing multi-process continuous forging of gears and improving production efficiency and processing accuracy. After the forging is completed at each station, the first driving member 403 (preferably a hydraulic rod) can be started. When the telescopic end of the hydraulic rod is extended, it will drive the fixed plate 402 to move upward. When the fixed plate 402 moves, it will slide with the guide shaft 404. The setting of the guide shaft 404 The fixed plate 402 moves more smoothly. When the fixed plate 402 moves, it drives the lifting column 401 to move upward. The lifting column 401 will push out the blank in the lower mold to cooperate with the handling device for handling. When the fixed plate 402 moves, it drives the driving shaft 405 to roll and cooperate in the spiral groove 505 on the fixed shaft 504, so that the fixed shaft 504 rotates. When the fixed shaft 504 rotates, it drives the stirring shaft 502 to rotate. When the stirring shaft 502 rotates, it can drive the stirring rod 503 to rotate. When the stirring rod 503 rotates, it can stir the lubricating oil in the oil storage tank 501. Stirring can fully mix the various components to ensure that the composition of the lubricating oil sprayed during spraying is consistent, avoiding unstable lubrication effect due to local uneven concentration. After stirring is completed, the oil can be transported to the nozzle through the pump and pipeline, and finally sprayed onto the mold surface in the form of mist;

[0043] During processing, the vacuum pump 604 is started, because its suction port is connected to the top of the filter 603 through a pipe, and the inlet of the guide cover 602 is aligned with the processing area, the waste slag generated by the processing will be adsorbed to the bottom of the filter 603, and the vacuum pump 604 cooperates with the filter 603 to absorb a large amount of waste slag, avoiding the accumulation of waste slag in the working area to affect the forging accuracy and equipment operation, and at the same time preventing the waste slag from entering the moving parts of the press to cause wear or jamming, thereby ensuring the stable operation of the press body 1. Cleaning up the waste slag in time can also improve the working environment and reduce the cleaning time of the operator. The filter 603 also It can prevent waste residue from entering the vacuum pump 604. When the processing is completed, the vacuum pump 604 is turned off, and the waste residue on the filter screen 603 loses suction and falls under the action of gravity. At this time, the second driving member 607 (preferably a hydraulic rod) is started, and the telescopic end of the hydraulic rod contracts to drive the sealing plate 606 to move downward, thereby sealing the inlet of the air guide cover 602. Then, the fan 608 is started to blow air downward, thereby promoting the waste residue on the filter screen 603 to fall off better. Since the sealing plate 606 has sealed the air guide cover 602, the waste residue will not float out and will eventually fall into the collection box 605 for centralized collection.

[0044] The cast gear workpiece is transported by the transport device to the collection vehicle 701 for collection. When collecting, the third driving member 705 (preferably a hydraulic rod) is started, and its telescopic end contracts to drive the fixed block 706 to move upward. Since the lifting rod 704 is installed on the fixed block 706, the lifting rod 704 drives the lifting plate 702 to rise synchronously. The height of the lifting plate 702 is increased to reduce the drop height of the gear workpiece to prevent the gear workpieces from hitting each other and reducing their quality due to the drop height being too high. After the collection is completed, the pull plate 710 is pulled upward, and the pull plate 710 drives the stop block 707 to move and slide with the guide rod 708. The guide rod 708 ensures that the pull plate 710 slides smoothly. At the same time, the second spring 709 contracts. When the stop block 707 no longer resists the lifting rod 704, the collection vehicle 701 can be taken out of the press body 1 to transport the gear workpiece in the collection vehicle 701.

[0045] When it is necessary to replace a different mold, the connecting shaft 211 can be rotated by the hand wheel 213, and the connecting shaft 211 drives the second bevel gear 212 to rotate. The second bevel gear 212 drives the first bevel gear 210 to rotate, and the first bevel gear 210 drives the transmission shaft 207 to rotate. The transmission shaft 207 rotates to drive the transmission rod 208 to rotate, and the transmission rod 208 drives the threaded sleeve 206 to rotate, so that the threaded sleeve 206 drives the sliding rod 205 on the two mounting seats 201 to slide. When the sliding rod 205 slides, it drives the mounting block 204 to slide so that the mounting block 204 no longer blocks the mounting rod 202. Since the mold is installed on the mounting plate 203, the two mounting rods 202 on the mounting plate 203 slide out to complete the disassembly. When molds of different models are installed, the mounting block 204 can be driven by the threaded sleeve 206 to resist and limit the mounting rod 202, and the installation can be completed. When the first drive member 8 drives the mounting base 201 to move, the first spring 305 of the second drive member 8 and the threaded ring 302 of the second drive member 8 are pressed together, thereby preventing the mounting base 201 from sliding out of the way and causing the mounting base 201 to move out of the way.
