[0067] Reference Figure 1 to Figure 12, which is the first embodiment of the present invention, proposes a continuous stamping device for automobile chassis, which is used to stamp a workpiece 1 into an automobile chassis. The loading direction of the workpiece 1 is horizontal, and the workpiece 1 has a plurality of positioning holes 101, including a stamping device 2, and the stamping device 2 has a stamping end 201 and a stamping table 202; a plurality of positioning columns 3, one end of the positioning columns 3 is arranged on the stamping table 202, and the positioning columns 3 are used to pass through the positioning holes 101; the upper mold 4 is arranged on the lower surface of the stamping end 201; the lower mold 5 is arranged on the upper surface of the stamping table 202, and a stamping space is formed between the upper mold 4 and the lower mold 5; a plurality of receiving plates 6 are slidably arranged on the positioning columns 3, and a plurality of receiving plates 6 are located on both sides of the lower mold 5.

[0068] In this embodiment, in order to solve the problem of inaccurate workpiece positioning in the automobile chassis stamping device in the related art, resulting in a high product failure rate, a continuous stamping device for automobile chassis is designed. In the production process of the automobile chassis, the workpiece 1 is first loaded. The workpiece 1 has a plurality of positioning holes 101, which play a positioning role in the subsequent processing process.

[0069] The punching device 2 includes a punching end 201 and a punching table 202. The punching end 201 can move up and down, driving the upper die 4 arranged on the lower surface of the punching end 201 to move closer to or away from the punching table 202. The upper surface of the punching table 202 is provided with a lower die 5. When the punching device 2 is running, a punching space is formed between the upper die 4 and the lower die 5, and the workpiece 1 is punched and formed into a car chassis in this punching space.

[0070] The number of the positioning posts 3 corresponds to the number of the positioning holes 101 on the workpiece 1. One end of the positioning post 3 is fixed on the punching table 202. When the workpiece 1 is loaded, the positioning post 3 passes through the positioning hole 101 on the workpiece 1 to ensure that the position of the workpiece 1 during the punching process is accurate.

[0071] There are several receiving plates 6, which are slidably arranged on the positioning pillars 3. These receiving plates 6 are located on both sides of the lower mold 5, and the receiving plates 6 can play a role in supporting the workpiece 1 when the workpiece 1 is punched.

[0072] The advantage is that by arranging the positioning column 3 and the positioning hole 101 on the workpiece 1 to cooperate, the position of the workpiece 1 during the stamping process can be ensured to be accurate, thereby improving the precision of stamping and forming and ensuring the quality of the automobile chassis. The device can achieve continuous stamping and improve production efficiency. The workpiece 1 can be quickly stamped and formed by the cooperation of the upper mold 4 and the lower mold 5 through lateral loading of the workpiece 1, which greatly shortens the production cycle.

[0073] Furthermore, an elastic member 7 is included, and two ends of the elastic member 7 are respectively in contact with the stamping platform 202 and the receiving plate 6 to provide a force to keep the receiving plate 6 away from the stamping platform 202 .

[0074] In this embodiment, the elastic member 7 can be a spring, and the two ends of the elastic member 7 are respectively in contact with the stamping table 202 and the receiving plate 6. When the stamping device 2 performs a stamping operation, the upper die 4 moves downward to squeeze the workpiece 1, and the workpiece 1 pushes the receiving plate 6 to slide along the positioning column 3 toward the stamping table 202, and the elastic member 7 is compressed. When the stamping is completed, the stamping end 201 of the stamping device 2 moves upward, and the upper die 4 leaves the workpiece 1. Under the restoring force of the elastic member 7, the receiving plate 6 moves away from the stamping table 202, and the stamped automobile chassis is pushed out of the stamping space, which is convenient for subsequent unloading operations.

[0075] The advantage is that the setting of the elastic member 7 enables the receiving plate 6 to automatically push the automobile chassis out of the stamping space after the stamping is completed, realizing the function of automatic material unloading, reducing manual operation and improving production efficiency. During the stamping process, the elastic member 7 can play a certain buffering role, reducing the impact force of the upper mold 4 on the lower mold 5, thereby extending the service life of the mold.

[0076] Furthermore, it also includes a loading device 8, which is arranged at the front end of the stamping device 2 and is used to move the workpiece 1 to the receiving plate 6. The loading device 8 includes a frame 81, one end of the frame 81 is abutted against one end of the stamping device 2; the receiving frame 82 is horizontally slidably arranged on the frame 81; there are a number of loading wheels 83, which are rotatably arranged on both sides of the frame 81, and the workpiece 1 is moved to the receiving frame 82 through the loading wheels 83.

[0077] In this embodiment, the feeding device 8 is arranged at the front end of the punching device 2. One end of the frame 81 abuts against one end of the punching device 2 to provide stable support for the feeding device 8. The material support frame 82 is arranged on the frame 81 for transverse sliding, and the material support frame 82 includes a sliding plate 821 and a lifting plate 822. The sliding plate 821 can slide transversely on the frame 81 to drive the entire material support frame 82 to move.

[0078] There are a number of feeding wheels 83, which are rotatably arranged on both sides of the frame 81. After the workpiece 1 is placed on the frame 81, the workpiece 1 can be smoothly moved to the receiving frame 82 through the rotation of the feeding wheels 83. Specifically, when the workpiece 1 needs to be loaded, the workpiece 1 is transported to the receiving frame 82 by the rotation of the feeding wheels 83 under the action of external thrust or its own gravity. The receiving frame 82 then moves the workpiece 1 to the receiving plate 6 of the punching device 2, ready for the punching operation.

[0079] The advantage is that the setting of the feeding device 8 enables the workpiece 1 to be quickly and accurately moved to the receiving plate 6 of the stamping device 2, thereby improving the feeding efficiency and providing a guarantee for continuous stamping production. The rotation of the feeding wheel 83 can smoothly convey the workpiece 1, reduce the wear and collision of the workpiece 1 during the conveying process, and ensure the quality of the workpiece 1. The receiving frame 82 is horizontally slidably arranged on the frame 81, and the position can be adjusted according to different production requirements to adapt to the feeding of workpieces 1 of different sizes and shapes.

[0080] Furthermore, the material support frame 82 has a positioning block 88 at one end close to the stamping device 2, and the loading device 8 also includes a first telescopic member 84, which is arranged at the end of the material support frame 82 away from the stamping device 2. After the first telescopic member 84 is extended, the extended end of the first telescopic member 84 abuts against one end of the workpiece 1, so that the other end of the workpiece 1 abuts against the positioning block 88; there are two second telescopic members 85, and the two second telescopic members 85 are respectively arranged on both sides of the material support frame 82. After the two second telescopic members 85 are extended, the extended ends of the second telescopic members 85 abut against both sides of the workpiece 1.

[0081] In this embodiment, a positioning block 88 is provided at one end of the material support frame 82 close to the punching device 2. The positioning block 88 is used to position one end of the workpiece 1 when the workpiece 1 is transported to the material support frame 82, so as to ensure that the position of the workpiece 1 on the material support frame 82 is accurate. The first telescopic member 84 is provided at the end of the material support frame 82 away from the punching device 2. When the workpiece 1 is transported to the material support frame 82, the first telescopic member 84 extends, and its extended end is close to the positioning block 88, so as to clamp and position the workpiece 1 from the other end of the workpiece 1. There are two second telescopic members 85, which are respectively provided on both sides of the material support frame 82. After the workpiece 1 is initially positioned on the material support frame 82, the two second telescopic members 85 extend, and their extended ends abut against both sides of the workpiece 1, so as to further position the workpiece 1 laterally, so as to ensure that the position of the workpiece 1 is stable during the process of being transported to the punching device 2.

[0082] The advantage is that, through the cooperation of the positioning block 88, the first telescopic member 84 and the second telescopic member 85, the workpiece 1 can be accurately positioned, ensuring that the workpiece 1 is accurately positioned when entering the stamping device 2, thereby improving the precision of stamping. The clamping effect of the first telescopic member 84 and the second telescopic member 85 makes the conveying process of the workpiece 1 on the material support frame 82 more stable, reducing the stamping error caused by shaking or displacement.

[0083] Furthermore, the material support frame 82 includes a sliding plate 821, which is laterally slidably arranged on the frame 81, and the first telescopic member 84 and the second telescopic member 85 are located on the sliding plate 821; the lifting plate 822 has a supporting portion and two first mounting portions 8221, the positioning block 88 is arranged on the first mounting portion 8221, the lifting plate 822 is C-shaped, and the lifting plate 822 is vertically slidably arranged on the sliding plate 821; one end of the first rotating plate 823 is rotatably arranged on one first mounting portion 8221; one end of the second rotating plate 8231 is rotatably arranged on another first mounting portion 8221, and after the first rotating plate 823 and the second rotating plate 8231 are rotated, the other end of the first rotating plate 823 and the other end of the second rotating plate 8231 abut against each other.

[0084] In this embodiment, the sliding plate 821 is arranged on the frame 81 for horizontal sliding, and is the main moving part of the material receiving frame 82. The first telescopic member 84 and the second telescopic member 85 are located on the sliding plate 821, and move with the movement of the sliding plate 821. The lifting plate 822 has a support portion and two first mounting portions 8221. The support portion is used to support the workpiece 1, and the two first mounting portions 8221 are respectively located on both sides of the lifting plate 822. The positioning block 88 is arranged on the first mounting portion 8221, and plays a role in positioning one end of the workpiece 1. The lifting plate 822 is a C-shaped structure as a whole, and is vertically slidably arranged on the sliding plate 821, and the height can be adjusted according to different work requirements. For example, when it is necessary to receive the workpiece 1, the lifting plate 822 is lowered to a position adapted to the loading height. After the workpiece 1 is transported to the lifting plate 822, the lifting plate 822 rises to a position that matches the height of the material receiving plate 6 of the punching device 2, so as to accurately transport the workpiece 1 to the punching device 2.

[0085] One end of the first rotating plate 823 is rotatably mounted on a first mounting portion 8221, and one end of the second rotating plate 8231 is rotatably mounted on another first mounting portion 8221. When the workpiece 1 is transported to the lifting plate 822, the first rotating plate 823 and the second rotating plate 8231 rotate, so that the other end of the first rotating plate 823 abuts against the other end of the second rotating plate 8231 to form a continuous material receiving platform, thereby preventing the workpiece 1 from jumping or shifting during the transport process.

[0086] The advantage is that the setting of the lifting plate 822 enables the material support frame 82 to adapt to the loading and punching devices 2 of different heights, thereby improving the versatility and adaptability of the equipment.

[0087] Furthermore, the material support frame 82 also includes a scissor-fork device 824, which has two scissor-fork devices 824. The two scissor-fork devices 824 are respectively arranged on both sides of the sliding plate 821. The two ends of one side of the scissor-fork device 824 are hinged to the sliding plate 821 and the lifting plate 822, and the two ends of the other side are slidably arranged on the sliding plate 821 and the lifting plate 822.

[0088] In this embodiment, there are two scissor-fork devices 824, which are respectively arranged on both sides of the sliding plate 821. The scissor-fork device 824 is composed of a plurality of cross-connected rods, and the lifting function is realized through the relative movement of the rods. One end of the scissor-fork device 824 is hinged to the sliding plate 821 and the lifting plate 822, and the other end is slidably arranged on the sliding plate 821 and the lifting plate 822. When the height of the lifting plate 822 needs to be adjusted, the sliding end of the scissor-fork device 824 is slid to expand or contract the scissor-fork device 824, thereby driving the lifting plate 822 to rise or fall.

[0089] The advantage is that the scissor device 824 has high structural stability and can provide a smooth lifting movement for the lifting plate 822, ensuring that the workpiece 1 does not shake or tilt during the lifting process, thereby improving the safety of loading and unloading. The scissor device 824 has a strong load-bearing capacity and can withstand heavier workpieces 1, and is suitable for the stamping production of automobile chassis of various specifications.

[0090] Furthermore, the material support frame 82 also includes a first transmission device, which is used to simultaneously drive the first rotating plate 823 and the second rotating plate 8231 to rotate in opposite directions. The first transmission device includes a driving gear 825, which is rotatably set on the lifting plate 822; a driven gear 826 is rotatably set on the lifting plate 822 and meshes with the driving gear 825; a first transmission gear 827 has a first gear tooth 8271 and a sector tooth 8272, and the sector center angle of the cross section of the sector tooth 8272 is 90°. 827 has two, two first transmission gears 827 are rotatably set on the lifting plate 822, and the two first gear teeth 8271 are respectively engaged with the driving gear 825 and the driven gear 826; the second transmission gear 828 has two, two second transmission gears 828 are rotatably set on the lifting plate 822, the second transmission gear 828 has second gear teeth 8281, the second gear teeth 8281 are engaged with the fan-shaped teeth 8272, and the two second transmission gears 828 are respectively connected to the first rotating plate 823 and the second rotating plate 8231.

[0091] In this embodiment, the material support frame 82 is provided with a first transmission device. The driving gear 825 is rotatably disposed on the lifting plate 822 and can be driven to rotate by a motor or other power device. The driven gear 826 is also rotatably disposed on the lifting plate 822 and meshes with the driving gear 825. When the driving gear 825 rotates, the driven gear 826 rotates accordingly.

[0092] The first transmission gear 827 has a first gear tooth 8271 and a sector tooth 8272, and the sector center angle of the cross section of the sector tooth 8272 is 90°. The two first transmission gears 827 are rotatably arranged on the lifting plate 822, and the two first gear teeth 8271 are respectively meshed with the driving gear 825 and the driven gear 826. When the driving gear 825 and the driven gear 826 rotate, the two first transmission gears 827 are driven to rotate.

[0093] The second transmission gear 828 has two, which are rotatably disposed on the lifting plate 822 and have second gear teeth 8281. The second gear teeth 8281 mesh with the sector teeth 8272. The two second transmission gears 828 are respectively connected to the first rotating plate 823 and the second rotating plate 8231 by chain transmission. When the first transmission gear 827 rotates, the sector teeth 8272 drives the second transmission gear 828 to rotate, and then drives the first rotating plate 823 and the second rotating plate 8231 to rotate in opposite directions through chain transmission.

[0094] For example, when the driving gear 825 rotates clockwise, the driven gear 826 rotates counterclockwise, thereby driving the two first transmission gears 827 to rotate. Since the central angle of the sector tooth 8272 is 90°, during the rotation of the first transmission gear 827, the sector tooth 8272 will mesh with the second gear tooth 8281 of the second transmission gear 828 within a certain angle range, thereby driving the second transmission gear 828 to rotate a certain angle. Through chain transmission, the first rotating plate 823 and the second rotating plate 8231 rotate in opposite directions.

[0095] The advantage is that the first transmission device can accurately control the rotation of the first rotating plate 823 and the second rotating plate 8231, ensuring that they can be accurately rotated to the right position when the workpiece 1 needs to be limited, thereby improving the reliability and stability of the equipment. Through the cooperation of the driving gear 825, the driven gear 826, the first transmission gear 827 and the second transmission gear 828, the first rotating plate 823 and the second rotating plate 8231 can achieve synchronous reverse rotation, ensuring that the limiting effect on the workpiece 1 is uniform.

[0096] Furthermore, the material support frame 82 also includes a second transmission device, which is used to drive the scissor-fork device 824 to move. The second transmission device includes a third transmission gear 8210, and the third transmission gear 8210 has two, and the two third transmission gears 8210 are respectively rotatably set on the sliding plate 821; there are two first racks 8211, and the two first racks 8211 are respectively longitudinally slidably set on the sliding plate 821; there are two fourth transmission gears 8212, and the two fourth transmission gears 8212 are rotatably set on the sliding plate 821, respectively located on both sides of the sliding plate 821, and the fourth transmission gear 8212 is meshed with the first rack 8211; there are two second racks 8213, and the two second racks 8213 are transversely slidably set on the sliding plate 821, respectively located on both sides of the sliding plate 821, the second rack 8213 is meshed with the fourth transmission gear 8212, and the second rack 8213 is connected to the scissor-fork device 824 slidingly on one end of the sliding plate 821, driving one end of the scissor-fork device 824 to slide.

[0097] In this embodiment, the material support frame 82 is provided with a second transmission device. There are two third transmission gears 8210, which are respectively rotatably arranged on the sliding plate 821. There are two first racks 8211, which are respectively longitudinally slidably arranged on the sliding plate 821. There are two fourth transmission gears 8212, which are respectively rotatably arranged on both sides of the sliding plate 821 and meshed with the first racks 8211. There are two second racks 8213, which are respectively transversely slidably arranged on both sides of the sliding plate 821.

[0098] When the height of the scissor-fork device 824 needs to be adjusted, the third transmission gear 8210 rotates. The rotation of the third transmission gear 8210 drives the first rack 8211 to slide longitudinally, and the sliding of the first rack 8211 drives the fourth transmission gear 8212 to rotate. The rotation of the fourth transmission gear 8212 drives the second rack 8213 to slide horizontally. One end of the second rack 8213 is connected to the scissor-fork device 824 sliding on one end of the sliding plate 821, thereby driving one end of the scissor-fork device 824 to slide, realizing the expansion or contraction of the scissor-fork device 824, and then adjusting the height of the lifting plate 822.

[0099] For example, when the third transmission gear 8210 rotates clockwise, it drives the first rack 8211 to slide longitudinally. The longitudinal sliding of the first rack 8211 causes the fourth transmission gear 8212 meshing therewith to rotate counterclockwise. The counterclockwise rotation of the fourth transmission gear 8212 drives the second rack 8213 to slide horizontally, thereby pushing the scissor-fork device 824 to expand and raise the lifting plate 822. Conversely, when the third transmission gear 8210 rotates counterclockwise, the scissor-fork device 824 can be retracted to lower the lifting plate 822.

[0100] The advantage is that the second transmission device can accurately control the movement of the scissor-fork device 824, thereby realizing accurate adjustment of the height of the lifting plate 822. This is very important for adapting to workpieces 1 of different sizes and different stamping process requirements, and can improve the precision and quality of stamping. Through the transmission of multiple gears and racks, the second transmission device can provide stable power output, ensuring that the scissor-fork device 824 is stable and reliable during movement, without shaking or jamming, and improving the stability and safety of the equipment.

[0101] Furthermore, the material support frame 82 also includes a transmission shaft 8214, one end of which is set on the first transmission gear 827 and rotates synchronously with the first transmission gear 827, and the other end is axially slidingly set on the third transmission gear 8210; the limit key 8215 is set on the transmission shaft 8214, so that the third transmission gear 8210 and the first transmission gear 827 rotate synchronously, and the first transmission device and the second transmission device move synchronously.

[0102] In this embodiment, the material support frame 82 is provided with a transmission shaft 8214 and a limit key 8215. One end of the transmission shaft 8214 is arranged on the first transmission gear 827 and rotates synchronously with the first transmission gear 827. The other end is vertically slidably arranged on the third transmission gear 8210. This design enables the transmission shaft 8214 to move up and down within a certain range to adapt to different working conditions.

[0103] The limit key 8215 is arranged on the transmission shaft 8214. When the transmission shaft 8214 contacts the third transmission gear 8210, the limit key 8215 can make the third transmission gear 8210 and the first transmission gear 827 rotate synchronously. Specifically, when the first transmission device and the second transmission device need to move synchronously, the transmission shaft 8214 moves downward so that its lower end contacts the third transmission gear 8210, and the limit key 8215 works to connect the two gears together to achieve synchronous rotation.

[0104] For example, in the process of loading and positioning the workpiece 1, it is necessary to adjust the angles of the first rotating plate 823 and the second rotating plate 8231 and the height of the lifting plate 822 at the same time. At this time, by controlling the movement of the transmission shaft 8214, the first transmission device and the second transmission device are synchronized. When the transmission shaft 8214 moves downward and the limit key 8215 causes the third transmission gear 8210 and the first transmission gear 827 to rotate synchronously, the rotation of the driving gear 825 not only drives the first transmission gear 827 to rotate, thereby controlling the rotation of the first rotating plate 823 and the second rotating plate 8231, but also drives the third transmission gear 8210 to rotate through the transmission shaft 8214, thereby starting the second transmission device and adjusting the height of the scissor device 824.

[0105] The advantage is that the setting of the transmission shaft 8214 and the limit key 8215 realizes the synchronous movement of the first transmission device and the second transmission device, so that when operating the workpiece 1, the rotation of the rotating plate and the height adjustment of the lifting plate 822 can be more accurately coordinated, thereby improving the working efficiency and precision of the equipment. The vertical sliding design of the transmission shaft 8214 makes it possible to flexibly control the synchronous or independent operation of the two transmission devices according to different work requirements. In some cases, the first transmission device or the second transmission device can be operated separately, and in operations that require precise coordination, synchronous movement can be achieved through the transmission shaft 8214, which increases the flexibility and adaptability of the equipment.

[0106] Furthermore, it also includes a second driving wheel 86, which is rotatably set on the sliding plate 821; the third rack 87 is set on the frame 81, and the second driving wheel 86 is meshed with the third rack 87. After the second driving wheel 86 rotates, the sliding plate 821 slides horizontally on the frame 81.

[0107] In this embodiment, the automobile chassis continuous stamping device 2 further includes a second driving wheel 86 and a third rack 87. The second driving wheel 86 is rotatably arranged on the sliding plate 821, and can be driven to rotate by a driving device such as a motor. The third rack 87 is arranged on the frame 81, and the second driving wheel 86 meshes with the third rack 87. When the second driving wheel 86 rotates, due to the meshing action with the third rack 87, the material receiving frame 82 slides horizontally on the frame 81.

[0108] The advantage is that the cooperation between the second driving wheel 86 and the third rack 87 enables the material support frame 82 to automatically slide horizontally on the frame 81, realizing the function of automatic loading, reducing manual operation and improving production efficiency. By controlling the rotation of the second driving wheel 86, the position of the material support frame 82 on the frame 81 can be accurately controlled to ensure that the workpiece 1 can be accurately transported to the designated position of the punching device 2, thereby improving the precision and quality of punching.

[0109] The working process of the equipment is as follows: in the initial state, the lifting plate 822 is in an unraised position, and the other end of the first rotating plate 823 and the other end of the second rotating plate 8231 are closely abutted to form a stable plane. At this time, the workpiece 1 is slowly loaded by the loading wheel 83, and under the stable conveying action, the workpiece 1 is smoothly moved to the lifting plate 822. Due to the abutment between the first rotating plate 823 and the second rotating plate 8231, a reliable support is provided for the workpiece 1, ensuring that the workpiece 1 will not slip during the loading process.

[0110] Then, the first telescopic member 84, the second telescopic member 85 and the positioning block 88 work together to accurately push the workpiece 1 to the designated position on the lifting plate 822. At this time, the driving gear 825 starts to rotate, and through the exquisite cooperation of the first transmission device and the second transmission device, the lifting plate 822 rises and the first rotating plate 823 and the second rotating plate 8231 rotate synchronously. The first rotating plate 823 and the second rotating plate 8231 rotate to a position parallel to the first mounting portion 8221, effectively avoiding mutual interference with the positioning rod during the loading process.

[0111] After the lifting and rotation are completed, the sliding plate 821 starts to slide smoothly on the frame 81, and the workpiece 1 is accurately moved to the top of the receiving plate 6. At this time, the driving gear 825 reverses. Since the first transmission gear 827 has a sector tooth 8272, it will not transmit with the second transmission gear 828 at the beginning of the reverse rotation of the driving gear 825, so it will not drive the first rotating plate 823 and the second rotating plate 8231 to rotate. Only the lifting plate 822 will drop half the height, and the workpiece 1 will fall exactly on the receiving plate 6. At the same time, the positioning column 3 will accurately pass through the positioning hole 101 on the workpiece 1 to further position the workpiece 1 to ensure that the position of the workpiece 1 during the stamping process is accurate.

[0112] After placing the workpiece 1, the sliding plate 821 moves away from the punching device 2, leaving the workpiece 1 on the receiving plate 6. After fully returning to the frame 81, the driving gear 825 is continuously reversed, so that the feeding device 8 gradually returns to the initial position, ready for the next feeding operation. The entire workflow is efficient, accurate, and stable, ensuring the smooth operation of the automobile chassis continuous punching device 2.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
