[0002] Auto parts processing is a key link in automobile manufacturing, involving many aspects such as material selection, processing technology, quality control and surface treatment. Common processing methods include forging, casting, machining and stamping, which are suitable for different types of parts. Materials usually choose metals (such as steel and aluminum alloys), plastics and composite materials to ensure strength and durability.

[0003] The automobile bending arm (also known as the control arm or suspension arm) is a key component in the automobile suspension system. It is responsible for connecting the body and the wheel to ensure the stability and controllability of the wheel during driving. Most of the automobile bending arm clamp forging is done by placing the heated material into the forging die through a stamping machine, applying pressure to make it flow and fill the die cavity to form the required clamp shape.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Reference Figure 1-8 A card forging device for a bending arm of an automobile comprises a stamping table 1 and a stamping device 2. The stamping table 1 is located inside the stamping device 2. A lower forging die 4 is arranged on the surface of the stamping table 1. An upper die 5 installed on the stamping device 2 is arranged above the lower forging die 4. A switching track 3 is arranged at the rear side of the stamping device 2. A switching mechanism 6 is arranged at the rear side of the lower forging die 4. The switching mechanism 6 slides on the rear side switching track 3. The switching mechanism 6 is movable and retractable on the switching track 3, which can realize the switching of the lower forging die 4 assembled thereon, the quick locking of the switching mechanism 6, and the fine adjustment of the lower forging die 4 assembled thereon, so that it cooperates with the upper die 5 to complete the stamping work of the heating card;

[0038] Furthermore, referring to Figure 2 , 5The switching mechanism 6 includes two left and right sliders 601, and the two sliders 601 slide on both sides of the exchange track 3 respectively. The upper side of the slider 601 is rotatably connected with a support frame 602, and a track seat 301 is fixed to the middle front side of the exchange track 3. A slider 3 611 that slides forward and backward is arranged inside the track seat 301. The outer ends of the two support frames 602 are rotatably connected to the slider 3 611. By bringing the two sliders 601 closer to the middle, the support frames 602 on both sides can be brought closer, and the slider 3 611 connected in the middle can be adjusted forward, so that the assembled lower forging die 4 can be pushed into the interior of the stamping equipment 2 and correspond to the upper die 5 on the upper side. Similarly, by unfolding the slider 601 to both sides, the slider 3 611 connected in the middle can be adjusted backward, so that the lower forging die 4 can be moved out of the stamping equipment 2 for replacement;

[0039] Furthermore, referring to Figure 3 , 5 , a support plate 603 that slides forward and backward is arranged at the lower side of the track seat 301, and positioning blocks 604 are fixed at both ends of the rear side of the support plate 603, and positioning grooves corresponding to the positioning blocks 604 are opened on one side of the two sliders 601, and a slide groove corresponding to the support plate 603 is opened on the surface of the stamping table 1, and a slide groove corresponding to the positioning block 604 is opened on one side of the replacement track 3, and a limit block 304 corresponding to the positioning block 604 is fixed in the slide groove. When the lower forging die 4 of the switching mechanism 6 is replaced, when the replaced lower forging die 4 penetrates into the interior of the stamping equipment 2, the slider 601 can be locked by the positioning blocks 604 at both ends of the support plate 603. At this time, the sliders 601 on both sides cannot slide left and right, thereby limiting the activity of the switching mechanism 6;

[0040] Furthermore, referring to Figure 8 , a telescopic rod 302 is fixed at the front end of the track seat 301, and the telescopic rod 302 is composed of a sleeve and a sliding rod. The sliding rod slides inside and outside the sleeve, and a spring is arranged inside the sleeve, and the outer end of the sliding rod is fixedly connected to the front end of the support plate 603, and the front end of the support plate 603 is rotatably connected with a limiting protrusion 303, and a limiting groove 403 corresponding to the limiting protrusion 303 is opened on the front side of the lower forging die 4. After the lower forging die 4 penetrates into the surface of the front side stamping table 1, the sliding rod is pushed into the sleeve so that the limiting protrusion 303 at the outer end of the sliding rod corresponds to the upper limiting groove 403, and then the limiting protrusion 303 is rotated 180 degrees, so that the protruding part of the lower end is transferred into the limiting groove 403, and then the connected sliding rod is released, and under the elastic force of the spring in the sleeve, the limiting protrusion 303 will be squeezed close to the rear side of the limiting groove 403;

[0041] Furthermore, referring to Figure 4 , 7The support frame 602 is provided with a slider 605 that slides forward and backward, the front end of the slider 605 is rotatably connected to an adjustment seat 608, the interior of the adjustment seat 608 is rotatably connected to a rotating shaft 609, and both ends of the interior of the adjustment seat 608 are provided with adjustment columns 610 that slide up and down. The rear end of the slider 605 is fixed with a sliding shaft 606, and the sliding shaft 606 slides forward and backward in the support frame 602, and a compression spring 607 is sleeved around the sliding shaft 606. When switching and assembling a new lower forging die 4, the adjustment seats 608 on the support frames 602 on both sides are first unfolded, and the front end of the adjustment seat 608 is provided with a positioning column 613. The front end of the support frame 602 is opened There is a slot corresponding to the positioning column 613, and the adjustment seat 608 is pushed toward the side of the slider 2 605, so that the positioning column 613 at the front end of the adjustment seat 608 is disengaged from the corresponding slot, and the adjustment seat 608 can be rotated to unfold. The slider 3 611 has plug-in columns 612 fixed on both sides of the surface. The lower forging die 4 has two fixed slots 401 corresponding to the plug-in columns 612, and the lower forging die 4 has two fixed slots 402 corresponding to the adjustment column 610 at the four corners of the lower side of the lower forging die 4. The lower forging die 4 has side grooves 404 of the slider 2 605 at the rear of both sides. The lower forging die 4 is positioned by a plurality of corresponding fixed slots on the lower side and the side grooves 404 on both sides.

[0042] Furthermore, referring to Figure 6 , 7 , the left and right sides of the surface of the stamping table 1 are provided with supporting columns 7 corresponding to the positioning columns 613, and the upper end surface of the supporting column 7 is flush with the lower end surface of the positioning column 613. When the sliders 601 on both sides are close to each other, the lower forging die 4 assembled in the middle is pushed inward, and when it moves to the deepest point, the positioning column 613 at the front end of the adjustment seat 608 corresponds to the left and right supporting columns 7 on the surface of the stamping table 1. At this time, the outer end of the adjustment seat 608 is leveraged on the supporting columns 7 on the surface of the stamping table 1, and the two ends of the rotating shaft 609 are fixed with bevel gears located inside the adjustment seat 608. Both ends of the part are connected with screws threadedly connected with the corresponding adjusting columns 610, and another bevel gear is fixed at the lower end of the screw. The other bevel gear at the lower end of the screw is meshed with the bevel gear at the end of the rotating shaft 609. By rotating the rotating shaft 609 in the adjusting seat 608, the bevel gears connected at both ends can be adjusted, and the screw fixed by another bevel gear can make the adjusting column 610 of the screw rise or move down in the adjusting seat 608, thereby realizing the adjustment of the lower forging die 4 assembled on the upper side, checking the mold gap and height, and ensuring that the mold is well closed.
