[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] like Figure 1-4 As shown, the present invention is a car chassis triangular arm shaping processing device; it includes a processing table 1, a back plate 2 fixedly connected to the top surface of the processing table 1, a processing unit 3 slidably connected to the front side of the back plate 2, a cavity opened inside the processing table 1, a limiting unit 4 fixedly connected to the bottom surface of the processing unit 3, and a storage unit 5 fixedly connected to the top surface of the processing table 1, and the storage unit 5 is located below the processing unit 3. The processing unit 3 includes a forward and reverse motor 31 fixedly connected inside the processing table 1. The output end of the forward and reverse motor 31 is fixedly connected to a rotating shaft 32. A belt 33 is slidably connected to the outer wall of the rotating shaft 32. A first ball screw 34 is slidably connected to the inner wall of the belt 33 on the side away from the rotating shaft 32. A lifting platform 35 is slidably connected to the inner wall of the back plate 2. The lifting platform 35 is slidably connected to the first ball screw 34. Multiple balance bars 39 are slidably connected to the inner wall of the lifting platform 35, and the balance bars 39 are fixedly connected to the back plate 2. A hydraulic press 36 is fixedly connected to the bottom surface of the lifting platform 35. A mold assembly 37 is fixedly connected to the top surface of the rotating shaft 32. Specifically, when using this device, the triangular arm needs to be placed on the top surface of the mold assembly 37. Then, the processing unit 3 is started, and the forward and reverse motor 31 starts to drive the rotating shaft 32 to rotate. The rotating shaft 32 drives the first ball screw 34 to rotate through the belt 33. The first ball screw 34 drives the lifting platform 35 to move downward through the thread on its surface. When the lifting platform 35 drives the hydraulic press 36 to move to the processing position, the hydraulic press 36 is started to shape the triangular arm. After processing, the mold assembly 37 is separated to facilitate the cleaning of the inside of the mold by the staff. This prevents the debris adhering to the surface of the triangular arm during the processing process from remaining on the mold surface and causing damage to the mold for the next shaping process. It also prevents the debris from accumulating inside the mold, thereby protecting the triangular arm during processing. The structure set in the storage unit 5 prevents the debris from affecting the movement of the structure.

[0024] Preferably, the mold assembly 37 includes a gear 371 fixedly connected to the top surface of the rotating shaft 32, a connecting cylinder 373 slidably connected to the outer wall of the gear 371 via a thread, a first spring 374 fixedly connected to the top surface of the connecting cylinder 373, a first mold 375 fixedly connected to the end of the first spring 374 away from the first spring 374, a plurality of toothed plates 376 slidably connected to the outer wall of the gear 371, a push plate 377 fixedly connected to the top surface of the toothed plates 376, and a second mold 378 slidably connected to one side of each of the three push plates 377; Specifically, after the triangular arm is processed by this device, the rotating shaft 32 drives the gear 371 to rotate. The gear 371 drives the push plate 377 to move through the teeth on the surface of the toothed plate 376. The push plate 377 drives the second mold 378 to move, so that the distance between the three push plates 377 gradually increases, thereby separating the bottom mold. This makes it easier for the operator to handle the processed debris, effectively avoiding the consequences of debris clogging the holes caused by automatic mechanical processing. At the same time, the second ball screw 372 drives the connecting cylinder 373 to move upward. The connecting cylinder 373 drives the first mold 375 to move upward through the first spring 374, so that the first mold 375 is fully exposed. This makes it easier for the operator to thoroughly process the top surface of the first mold 375, thereby improving the service life of the mold and reducing the maintenance cycle of the mold during operation, thus effectively improving the processing efficiency of this device.

[0025] Preferably, a locking block 379 is slidably connected between the push plate 377 and the second mold 378, and an insert plate 3710 is slidably connected to the inner wall of the locking block 379, and the insert plate 3710 is slidably connected to the push plate 377. Specifically, by setting up the cooperation between the card block 379 and the insertion plate 3710, the replacement of the second mold 378 can be facilitated, thereby allowing the replacement of a single second mold 378, reducing the consumption of mold material, and thus improving the processing efficiency of this device.

[0026] Preferably, a support frame 38 is fixedly connected to the top surface of the lifting platform 35, the support frame 38 is slidably connected to the back plate 2, and a slot matching the insertion plate 3710 is opened on the top surface of the push plate 377. Specifically, by setting up a triangular support frame 38, the pressure is distributed from the lifting platform 35 to the range of the back plate 2 during the process of the hydraulic press 36 shaping the triangular arm, thereby preventing the lifting platform 35 from deforming or being damaged after long-term use and protecting the structure of the device itself.

[0027] Preferably, the storage unit 5 includes a guide frame 52 fixedly connected to the toothed plate 376 on the side near the gear 371, and a storage box 53 slidably connected to the inner wall of the processing table 1, with the storage box 53 located below the guide frame 52. Specifically, the guide frame 52 and the storage box 53 are used to collect the fallen debris. By setting the guide frame 52 and the rounded corners inside, the fallen debris is guided into the storage box 53 for collection, reducing the accumulation of debris on the top surface of the processing table 1, thereby keeping the processing table clean and preventing debris from causing injury to workers during processing.

[0028] Ideally, a second protective strip 54 is fixedly connected to the bottom surface of the guide frame 52, and a first protective strip 51 is fixedly connected to the side of the push plate 377 away from the second mold 378. Specifically, the structure with the first protective belt 51 prevents debris from falling and obstructing the movement of the push plate 377, thus ensuring the smooth operation of the structure. The structure with the second protective belt 54 connects the guide frame 52 and the storage box 53, allowing the fallen debris to smoothly enter the interior of the storage box 53, facilitating subsequent processing by the staff.

[0029] Preferably, the limiting unit 4 includes a pressure frame 41 fixedly connected to the bottom surface of the lifting platform 35, a limiting block 42 slidably connected to the side wall of the push plate 377, a sliding plate 43 connected between the push plate 377 and the limiting block 42, the sliding plate 43 being fixedly connected to the push plate 377, a second spring 47 slidably sleeved on the outer wall of the fixed shaft 44, and a slot matching the limiting block 42 opened on the top surface of the processing table 1; Specifically, after the lifting platform 35 moves to the working position, the lifting platform 35 drives the pressure frame 41 to pressurize the limiting block 42, causing the limiting block 42 to move the slide plate 43 downward. As the slide plate 43 moves downward along the trajectory of the fixed shaft 44, it compresses the second spring 47, causing the bottom of the slide plate 43 to insert into the groove inside the slot opened on the top surface of the processing table 1. This allows the pressure of the hydraulic press 36 during the processing of the triangular arm to be transmitted to the second mold 378. The second mold 378 transmits the pressure to the position of the push plate 377, which is limited by the limiting block 42, thereby improving the pressure resistance of the push plate 377 and preventing the push plate 377 from deforming under long-term pressure, ensuring the safety of the structure.

[0030] Preferably, the inner wall of the limiting block 42 is provided with a groove 46 that matches the sliding plate 43, and a roller 45 is fixedly connected to the bottom surface of the limiting block 42; Specifically, by setting the roller 45 to slide inside the slot, the structure of the roller 45 is corrected during the movement of the push plate 377, maintaining the stability of the push plate 377 during the movement, and at the same time, the slide groove 46 is set to accommodate the structure of the second spring 47.

[0031] Preferably, a third ball screw 411 is rotatably connected between the front and rear inner sides of the pressure frame 41, a slider 412 is slidably connected to the outer wall of the third ball screw 411, a brush plate 413 is rotatably connected to the inner wall of the slider 412, a push plate 414 is fixedly connected to the top surface of the limit block 42, a column gear 415 is fixedly connected to the front end face of the third ball screw 411, a rack plate 416 is slidably connected to the front sides of the left and right sides of the pressure frame 41 respectively, a dust cover 417 is slidably connected to the front side of the rack plate 416, and the dust cover 417 is fixedly connected to the pressure frame 41. Specifically, when using this device, as the structure moves to the lifting platform 35, which drives the pressure frame 41 upward, and the first mold 375 and the second mold 378 are about to separate, the rack plate 416 drives the column gear 415 to rotate. The column gear 415 drives the third ball screw 411 to rotate. The rotation of the third ball screw 411 causes the slider 412 on its surface to move towards the balance bar. During the movement, the slider 412 drives the brush plate 413, which is freed from the constraint of the push plate 414, to move. The elastic wear-resistant brush head on the surface of the brush plate 413 performs a simple cleaning treatment on the surface of the first mold 375, pushing the residue on the surface of the first mold 375 into the interior of the rear guide frame 52 for collection. The debris is collected and processed inside the collection box 53. When the lifting platform moves the pressure frame 41 downward, the rack plate 416 drives the slider 412 to rotate in the opposite direction, causing the slider 412 to reset the brush plate 413. Then, after the brush plate 413 contacts the push plate 414, it rotates, causing the push plate 414 to rotate 90 degrees. This does not affect the processing work of the device itself. By setting the structure of the dust cover 417, the debris is prevented from falling and adhering to the surface of the column gear 415 during the lifting process of the brush plate 413, ensuring the smooth operation of the structure. Through the cooperation between the structures, the machine can perform preliminary cleaning, reducing the debris adhering to the mold surface, thus making it easier for the staff to carry out subsequent processing.

[0032] The work process is as follows: When using this device, the triangular arm needs to be placed on the top surface of the mold assembly 37. Then, the processing unit 3 is started, and the forward and reverse motor 31 starts to drive the rotating shaft 32 to rotate. The rotating shaft 32 drives the first ball screw 34 to rotate through the belt 33. The first ball screw 34 drives the lifting platform 35 to move downward through the thread on its surface. When the lifting platform 35 drives the hydraulic press 36 to the processing position, the hydraulic press 36 is started to shape the triangular arm. After processing, the mold assembly 37 is separated to facilitate the cleaning of the mold interior by the operator. This prevents the debris adhering to the surface of the triangular arm during the processing process from remaining on the mold surface and causing damage to the mold for the next shaping process. It also prevents debris from accumulating inside the mold, thus protecting the triangular arm during processing. The structure set in the storage unit 5 prevents debris from affecting the movement of the structure. The structure set in the limiting unit 4 enhances the stability of the mold and ensures the stability of the mold during use.

[0033] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
