Description

Technical Field

[0001] The invention relates to the technical field of high-horsepower tractor production, in particular to a tractor chassis forging and drawing device. Background Art

[0002] High-horsepower tractors are self-propelled power machines used to pull and drive operating machinery to complete various mobile operations. During the production process of high-horsepower tractors, the chassis needs to be forged, so a drawing device is needed to draw and form the raw bars of the chassis' shaft or rod components, such as drive shafts and balance bars.

[0003] Currently, when a drawing machine is used to draw chassis shaft materials, workers usually first pass the end of the raw material bar through the die, then use a mobile trolley to clamp the end of the bar, and then the mobile trolley is hooked onto the chain. The chain can then drive the mobile trolley to draw and form the bar. However, in actual use, the bar between the die outlet and the clamping point will form a suspended section due to lack of support. Under the action of gravity, additional bending moment will be generated, causing the axial stress field to shift, which will easily increase the wall thickness deviation of the drawing section, thereby affecting the overall drawing effect.

[0015] The present application provides a tractor chassis forging and drawing device, which has the following advantages:

[0016] 1、The present application realizes automatic lifting of the supporting mechanism through magnetic attraction linkage, when the moving trolley moves away from the mold, the magnet drives the sliding block to move the guide seat, the sliding column is lifted along the inclined groove to the horizontal groove for locking, the supporting rod pushes the pulley to contact the bottom of the bar to form support, this design effectively eliminates the suspended section between the mold outlet and the clamping point, avoids the stress field deviation caused by the bending moment of the bar due to its own weight, the pulley structure not only provides stable support but also reduces surface scratches, and significantly improves the drawing process quality.

[0017] 2. In the present invention, after the rod is completely pulled out, the mobile trolley drives the fourth magnet to push the third magnet, and the synchronous rod is pushed to move horizontally through the convex column rotating rod. All vertical rods cooperate to push the slider to reset. During the downward movement of the guide seat, the slide column slides back to the bottom of the guide groove, so that the supported rod automatically rolls out along the inclined surface of the guide plate.

When the rods roll in, they are buffered by the rubber baffle and press the support plate. The linked T-plate drives the rotating plate to form a lever effect, so that the far-end buffer partition rises to form isolation. When subsequent rods hit the buffer partition, the support plate is triggered to press down again, driving the adjacent partitions to rise in turn, forming a chain buffer protection. This design realizes the linkage of multi-stage buffer devices through the weight of the material, effectively preventing rigid collision damage between rods. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] See also Figures 1 to 4 The present invention provides a technical solution: a tractor chassis forging and drawing device, comprising a machine base 1 and a support assembly 6, a die 2 is arranged at one end of the top of the machine base 1, and a chain conveyor 3 is arranged inside the machine base 1, a mobile trolley 4 is connected to the top of the machine base 1, and a clamp 5 is arranged on the top of the mobile trolley 4, the support assembly 6 is connected to one side of the mobile trolley 4, and the support assembly 6 includes a drive plate 601, a drive plate 601 is arranged on one side of the mobile trolley 4, and a first magnet 602 is fixed to one side of the lower end of the drive plate 601, a limiting hole 603 is opened on one side of the machine base 1, and a slider 604 is slidably connected to the inside of the limiting hole 603, and the slider 6 A second magnet 605 is fixed to one end of 04, and a guide seat 606 is placed on the other end of the slider 604, and the guide seat 606 is slidably connected to the base 1. A guide groove 607 is opened on one side of the guide seat 606, and a slide column 608 is slidably connected inside the guide groove 607, and a support rod 609 is fixed to one end of the slide column 608. A pulley 610 is placed on the upper end of the support rod 609, and a guide plate 611 is slidably connected to the outer middle part of the support rod 609, and the guide plate 611 is fixedly connected to the base 1. The guide groove 607 is composed of two sections of horizontal grooves connected with an oblique groove in between, and the width of the guide groove 607 is equal to the diameter of the slide column 608;

[0028] The specific operation is as follows: in the process of the moving trolley 4 moving toward the mold 2, since the slide column 608 is located inside the lower end of the guide groove 607, the height of the pulley 610 is lower than the moving trolley 4, so it will not block the movement of the moving trolley 4, and when the clamp 5 is used to clamp the bar and the upper hook is controlled to hook the chain of the chain conveyor 3 to pull the bar, as the moving trolley 4 moves, it can also drive the driving plate 601 to move synchronously, and when the first magnet 602 on the driving plate 601 is aligned with the second magnet 605, under the action of the magnetic attraction, it can drive the slider 604 to move from one end of the limiting hole 603 to the other end, so the guide seat 606 can be controlled to slide horizontally at the same time. The slide column 608 slides along the inclined groove of the guide groove 607 to the horizontal groove at the upper end to limit its height position. The support rod 609 will drive the pulley 610 to contact the bottom of the rod under the limit of the guide plate 611, thereby limiting the support of the rod. At the same time, the rotatable pulley 610 is used to avoid scratches on the outside of the rod. Therefore, during the drawing process, when the mobile trolley 4 moves away from the upper part of the pulley 610, the pulley 610 can be automatically moved up and support the bottom of the rod, preventing the rod between the outlet of the mold 2 and the clamping point from forming a suspended section due to lack of support, and avoiding the additional bending moment of the rod under the action of gravity, which causes the axial stress field to shift, which is beneficial to improving the drawing effect of the rod.

[0029] See also Figures 2 to 5 , a discharge assembly 7 is connected to one side of the machine base 1, and the discharge assembly 7 includes a transmission rod 701, a transmission rod 701 is slidably connected to one side of the machine base 1, and a third magnet 702 is arranged on the end of the transmission rod 701, and a boss 703 is fixed to the middle part of one side of the transmission rod 701, and a rotating rod 704 is slidably connected to the outer side of the boss 703, and a fixed column 705 is slidably connected to the lower end of the rotating rod 704, and a synchronization rod 706 is fixed to the end of the fixed column 705, and a vertical rod 707 is equidistantly arranged on the top of the synchronization rod 706, the rotating rod 704 is rotatably connected to the machine base 1, and the synchronization rod 706 is slidably connected to the machine base 1, a guide plate 708 is fixed inside the machine base 1, and a discharge port 709 is opened on the other side of the machine base 1, a fourth magnet 710 is fixed to the middle part of the driving plate 601, the guide plate 708 is obtuse-angled, and the guide plates 708 are equidistantly distributed with respect to the interior of the machine base 1;

[0030] The specific operation is as follows: in the process of supporting the rod, the slider 604 will move to one side of the vertical rod 707, and when the rod is completely pulled out of the mold 2, the clamp 5 releases the end of the rod. At this time, as the moving trolley 4 moves, the driving plate 601 will drive the fourth magnet 710 to fit with the third magnet 702, and apply force to the transmission rod 701. The protruding column 703 pushes the rotating rod 704 to rotate it, and the synchronous rod 706 can be driven to move horizontally through the fixed column 705, so that all the vertical rods 707 can push the slider 604 at the same time, and all the guide rods 707 can be driven to move horizontally. The seat 606 will move toward the mold 2, and the slide column 608 will slide to the lower end of the guide groove 607. Therefore, in the process of the pulley 610 moving downward, the rod can be moved to the inclined surface of the guide plate 708, and the rod will automatically roll out through the discharge port 709 to complete the unloading. Subsequently, when the mobile carriage 4 moves back to the mold 2, the driving plate 601 will also attract the third magnet 702 through the fourth magnet 710, which can first drive the transmission rod 701 to move back. Similarly, as the rotating rod 704 rotates, the synchronization rod 706 can be moved back and reset, which is convenient for subsequent reuse.

[0031] See also Figure 6 and Figure 7 , a storage platform 8 is provided on the other side of the machine base 1, and a buffer assembly 9 is provided inside the storage platform 8, and the buffer assembly 9 includes a buffer baffle 901, a buffer baffle 901 is placed at one end of the top of the storage platform 8, and the length of the buffer baffle 901 is consistent with the length of the storage platform 8, the storage platform 8 is rotatably connected to a support plate 902, and the bottom of the support plate 902 is slidably connected to a T-shaped plate 903, and the lower end of the T-shaped plate 903 is rotatably connected to a rotating plate 904, the middle part of the rotating plate 904 is rotatably connected to a hanging plate 905, and one end of the hanging plate 905 is internally slidably connected to a driving column 906, and a buffer partition 907 is fixed to the outer side of the middle part of the driving column 906, the hanging plate 905 is fixedly connected to the storage platform 8, and the storage platform 8 is slidably connected to the buffer partition 907;

[0032] The specific operation is as follows: when there are no bars on the storage platform 8, since the buffer partition 907 has a longer force arm on the rotating plate 904, the buffer partition 907 is easily moved down and retracted into the interior of the storage platform 8 under the action of gravity. When the bars roll from the discharge port 709 to the upper end of the storage platform 8, the rubber buffer baffle 901 is used to buffer the bars to prevent the bars from being damaged due to rigid collision. At the same time, the bars will also squeeze the support plate 902 due to gravity, so that the support plate 902 is flush with the top of the storage platform 8. At this time, the support plate 902 will squeeze the T-plate 903 to drive the left end of the rotating plate 904 to move downward. The other end will drive the buffer partition 907 to move upward through the driving column 906. At the same time, since the hanging plate 905 is close to the left end of the rotating plate 904, the moving distance of the buffer partition 907 is increased, so that it is extended from the inside of the storage platform 8. Therefore, when the next rod rolls onto the storage platform 8, the buffer partition 907 can be used to buffer the next rod to avoid rigid collision and damage between the two rods. After the buffer partition 907 blocks the next rod, the rod will press the support plate 902 below, which can automatically extend the side buffer partition 907 again without manual control, which is more convenient.

[0033] In summary, when using this tractor chassis forging and drawing device, first the end of the bar is passed through the die 2, and the clamp 5 on the mobile trolley 4 is used to clamp the bar, and the upper hook is controlled to hook the chain of the chain conveyor 3 to draw the bar. As the mobile trolley 4 moves, it can also drive the driving plate 601 to move synchronously, and when the first magnet 602 on the driving plate 601 is aligned with the second magnet 605, under the action of the magnetic attraction, it can drive the slider 604 to move from one end of the limiting hole 603 to the other end, so it can simultaneously The guide seat 606 is controlled to slide horizontally, so that the slide post 608 slides along the inclined groove of the guide groove 607 to the transverse groove at the upper end, and its height position is limited. The support rod 609 will drive the pulley 610 to contact the bottom of the rod under the limit of the guide plate 611, thereby limiting the position of the rod. At the same time, the rotatable pulley 610 is used to avoid scratching the outside of the rod. Therefore, during the drawing process, when the mobile carriage 4 moves away from the upper part of the pulley 610, the pulley 610 can automatically move up and support the bottom of the rod;

[0034] Then, when the rod is completely pulled out from the mold 2, the clamp 5 releases the end of the rod. At this time, as the moving trolley 4 moves, the driving plate 601 drives the fourth magnet 710 to fit with the third magnet 702 and applies force to the transmission rod 701. The protruding column 703 pushes the rotating rod 704 to rotate, which can drive the synchronous rod 706 to move horizontally through the fixed column 705, so that all the vertical rods 707 can push the slider 604 at the same time, and all the guide seats 606 will move toward the mold 2. The sliding column 608 slides to the lower end of the guide groove 607. Therefore, in the process of the pulley 610 moving downward, the rod can be moved to the inclined surface of the guide plate 708, and the rod will automatically roll out through the discharge port 709 to complete the unloading.

[0035] Then, when the rod rolls from the discharge port 709 to the upper end of the storage platform 8, the rubber buffer baffle 901 is used to buffer the rod to prevent the rod from being damaged by rigid collision. At the same time, the rod will squeeze the support plate 902 due to gravity, so that the support plate 902 is flush with the top of the storage platform 8. At this time, the support plate 902 will squeeze the T-shaped plate 903 to drive the left end of the rotating plate 904 to move downward, and its other end will drive the buffer partition 907 to move upward through the driving column 906. At the same time, because the hanging plate 905 is close to the left end of the rotating plate 904, the moving distance of the buffer partition 907 is increased, so that it extends from the inside of the storage platform 8. Therefore, when the next rod rolls onto the storage platform 8, the buffer partition 907 can be used to buffer the next rod to avoid rigid collision and damage between the two rods.

[0036] Finally, when the hook on the mobile trolley 4 is controlled to release the material strip and the wheels are driven to move the mobile trolley 4 back to the mold 2, the driving plate 601 will also attract the third magnet 702 through the fourth magnet 710, and can first drive the transmission rod 701 to move back. Similarly, as the rotating rod 704 rotates, the synchronization rod 706 can be moved back and reset, which is convenient for subsequent reuse. In the process of the mobile trolley 4 moving toward the mold 2, since the sliding column 608 is located inside the lower end of the guide groove 607, the height of the pulley 610 is lower than the mobile trolley 4, so it will not cause obstruction to the movement of the mobile trolley 4.
