Detailed implementation manners

[0034] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] Example 1, as Figure 1 , Figure 2 and Figure 3As shown in the figure, a stamping and shaping device for the bottom plate of an automotive seat frame includes a machine tool housing 1. A ventilation device 3 communicating with its inner cavity is fixedly connected to the upper end of the machine tool housing 1. Isolation doors 4 are symmetrically rotatably connected to the left and right sides of the front end of the machine tool housing 1. An observation window is arranged on the front side of the isolation door 4. A control terminal is fixedly connected to the front end of the machine tool housing 1. Four support legs are fixedly connected to the lower end of the machine tool housing 1 in a rectangular distribution. Feeding structures 2 are symmetrically arranged on the inner surfaces of two installation grooves 11 symmetrically opened on the front side of the inner surface of the machine tool housing 1. A stamping and shaping structure 5 is arranged at the rear part of the inner cavity of the machine tool housing 1. A number of electric rollers 6 are fixedly installed in an array on the front part of the inner surface of the machine tool housing 1. A baffle plate is fixedly connected to the inner surface of the machine tool housing 1 corresponding to the end position of the electric rollers 6.

[0036] It should be specifically noted that the above control terminal is a commonly used controller for machine tools in the prior art, which is used to input processing programs, control the start, stop, forward and reverse operation of electrical equipment, and is a conventional technical means in the prior art and has been widely used in the prior art. The present invention will not elaborate on its internal structure, operating principle, wiring and control method.

[0037] In addition, the above electric roller 6 is internally provided with a small motor, which can drive the roller to rotate through the rotation of the motor, and then drive the material to move horizontally on its upper part. The bottom plate raw material is conveyed inward through the electric roller 6, and is blocked at a predetermined position by the baffle plate to realize the positioning of the raw material. This is a conventional technical means in the prior art, and the present invention will not display and elaborate on its specific internal structure and working process.

[0038] During the operation of this embodiment, first, the bottom plate raw material is conveyed inward by the action of the electric roller 6 and the baffle plate, and the bottom plate raw material is sent into the stamping and shaping structure 5 through the feeding structure 2. The stamping and shaping structure 5 performs stamping, shaping and punching operations on the bottom plate raw material, simplifies the traditional process flow, improves production efficiency. At the same time, automatic feeding is realized through the feeding structure 2 and the electric roller 6, reducing the manual operation link, reducing the labor intensity, reducing the probability of accidents, and improving the overall production safety and stability.

[0039] Embodiment 2: On the basis of Embodiment 1, this embodiment drives the electromagnet 22 to move along a predetermined trajectory through the cooperation of the guiding component 24 and the U-shaped bracket 23, so as to feed the bottom plate raw material above the electric roller 6 into the stamping and shaping structure 5. After the processing is completed, the finished product is taken out from the stamping and shaping structure 5 and placed on the upper layer of the electric roller 6 for sending out. This ensures the accurate conveying of the bottom plate raw material and the efficient output of the finished product, relatively reduces the participation and influence of manual labor, further optimizes the production process, improves the automation level, reduces human errors, enhances the consistency and reliability of product quality, and realizes an efficient, accurate and safe modern production mode.

[0040] Specifically, to realize the conveying of the bottom plate raw material and the recovery of the finished product, refer to Figure 3 , the feeding structure 2 includes a U-shaped bracket 23. One side of the U-shaped bracket 23 close to the inner wall of the machine tool housing 1 is fixedly connected with a roller 21. The lower end of the U-shaped bracket 23 is symmetrically and fixedly connected with electromagnets 22 at the front and rear. The inner surfaces of both installation grooves 11 are provided with guiding components 24, and the roller 21 slides inside the guiding component 24.

[0041] The above electromagnet 22 is a conventional electromagnetic device in the prior art. It has magnetism when powered on and loses magnetism when powered off. It grabs the bottom plate finished product or raw material through electromagnetic force, which is a mature technical means in the prior art. In the present invention, its specific operation process and principle will not be shown and described in detail.

[0042] The guiding component 24 drives the U-shaped bracket 23 to move along a U-shaped trajectory inside the machine tool housing 1, so as to feed the bottom plate raw material above the electric roller 6 into the stamping and shaping structure 5. After the processing is completed, the finished product is taken out from the stamping and shaping structure 5 and placed on the upper layer of the electric roller 6 for sending out, realizing the automatic conveying of the bottom plate raw material and the recovery of the finished product, improving the coherence and efficiency of the production line, and reducing the frequency of manual intervention;

[0043] Compared with the traditional manual feeding, firstly, the accuracy is higher, avoiding human errors; secondly, the speed is faster, shortening the production cycle; finally, the operation safety is improved, reducing the risk of work-related injuries.

[0044] Furthermore, to drive the steel plate to move on a predetermined trajectory and realize automatic loading and unloading, refer to Figure 4 、 Figure 5 and Figure 6, the guiding component 24 includes a driving slider 246 slidably connected to the inner surface of the installation groove 11. The inner surface of the driving slider 246 is threadedly connected to a threaded rod 247 rotatably connected to the inner surface of the installation groove 11. The front end of the machine tool housing 1 is fixedly connected to a driving motor 245 drivingly connected to the threaded rod 247. The inner surface of the driving slider 246 is snap-connected to a guiding slider 248 slidably connected to the inner surface of the installation groove 11. The left end of the guiding slider 248 is provided with a V-shaped guiding groove 2481 communicating with the right end. The inner surface of the installation groove 11 on the side close to the inner cavity of the machine tool housing 1 is provided with a U-shaped guiding groove 244 communicating with the inner cavity of the machine tool housing 1. The inner surfaces of the V-shaped guiding groove 2481 and the U-shaped guiding groove 244 are jointly slidably connected to the outer surface of the roller 21. The inner surface of the machine tool housing 1 corresponding to the horizontal part of the U-shaped guiding groove 244 is fixedly connected with a limiting groove 241. A hollow slider 242 is slidably connected to the inner surface of the limiting groove 241. A first limiting rod 243 fixedly connected to the upper end of the U-shaped bracket 23 is slidably connected to the inner surface of the hollow slider 242.

[0045] Further, to drive the bottom plate raw material to switch between the front station and the rear station, refer to Figure 6 , the V-shaped guiding groove 2481 is in a V shape with an opening downward, and its vertex is at the same height as the horizontal part of the U-shaped guiding groove 244. The lowest point of the V-shaped guiding groove 2481 and the two lowest points of the path of the U-shaped guiding groove 244 in the front and rear are on the same horizontal line.

[0046] In summary, during the operation of this embodiment, the driving motor 245 drives the threaded rod 247 to rotate. During the rotation, the driving slider 246 is driven to slide horizontally through the threaded action between the threaded rod 247 and the driving slider 246. Further, the guiding slider 248 will slide horizontally in the installation groove 11 following the movement of the driving slider 246. During the sliding of the guiding slider 248, the roller 21 has a total of three motion states:

[0047] First, when the roller 21 is in the front vertical part of the U-shaped guiding groove 244 and behind the V-shaped guiding groove 2481, the guiding slider 248 moves backward, and can drive the roller 21 to move upward along the vertical part of the U-shaped guiding groove 244 through the V-shaped guiding groove 2481 until it enters the highest point of the V-shaped guiding groove 2481.

[0048] Second, when the roller 21 is at the highest point of the V-shaped guiding groove 2481 and within the horizontal track of the U-shaped guiding groove 244, the guiding slider 248 continues to slide backward in the installation groove 11, and will drive the roller 21 to move backward along the horizontal track of the U-shaped guiding groove 244.

[0049] Thirdly, when the roller 21 moves to the vertical part at the rear side of the U-shaped guiding groove 244 and is at the highest point of the V-shaped guiding groove 2481, when the guiding slider 248 continues to move backward, it will press the roller 21 to move downward along the vertical track of the U-shaped guiding groove 244 through the V-shaped guiding groove 2481 until it returns to the lower part of the vertical part of the U-shaped guiding groove 244. At this time, the roller 21 is at the lowest position of the U-shaped guiding groove 244 and the V-shaped guiding groove 2481.

[0050] During this process, the roller 21 will drive the U-shaped bracket 23 to move along the track of the U-shaped guiding groove 244, realizing taking materials on the electric roller 6 and placing them in the stamping and shaping structure 5. The same is true for the finished products after processing. When the driving motor 245 moves in the reverse direction, the roller 21 will move in the reverse direction along the above steps, and then take out the finished product materials in the stamping and shaping structure 5 and put them back above the electric roller 6.

[0051] Similarly, since the roller 21 will rotate, to limit the rotation of the U-shaped bracket 23 so that it can only move horizontally, the hollow slider 242 sliding in the limiting groove 241 installed on the inner wall of the machine tool housing 1 can only move horizontally under the limitation of the limiting groove 241. The limiting rod one 243 sliding inside it is connected to the U-shaped bracket 23 and can limit the U-shaped bracket 23 during its horizontal movement, thereby realizing the horizontal movement of the U-shaped bracket 23 and restricting the relative rotation of the U-shaped bracket 23 and the roller 21.

[0052] Embodiment 3: On the basis of Embodiment 2, this embodiment further drives the stamping assembly 53 to descend through the electric telescopic rod 51 arranged on the top wall of the inner cavity of the machine tool housing 1. Through the cooperation of the stamping assembly 53 and the supporting assembly 54, the bottom plate material is stamped and shaped, thereby realizing the precise forming of the bottom plate material. The electric telescopic rod 51 drives the stamping assembly 53 to descend to a predetermined position, and the supporting assembly 54 cooperates with the stamping assembly 53 to apply pressure, so that the bottom plate material reaches the preset shape during the stamping process. The cooperation of the supporting table 541, the pressing block 535 and the shaping part 536 is used to realize one-time forming, simplify the processing flow, thereby improving the production efficiency and ensuring the stability of the product quality.

[0053] Specifically, to realize the stamping and shaping of the bottom plate raw material, refer to Figure 7 , the stamping and shaping structure 5 includes an electric telescopic rod 51 fixedly connected to the top wall of the inner cavity of the machine tool housing 1. The top wall of the inner cavity of the machine tool housing 1 is symmetrically and fixedly connected with limiting rods two 52 on the left and right. The piston rods of the limiting rods two 52 and the output piston rod of the electric telescopic rod 51 are jointly fixedly connected with a stamping assembly 53. Compression plates 55 are fixedly connected to both sides of the stamping assembly 53. A supporting assembly 54 is arranged on the bottom wall of the inner cavity of the machine tool housing 1.

[0054] It should be specifically noted that the above-mentioned second limiting rod 52 is a conventional telescopic device in the prior art. After being powered on, it can drive the piston rod to extend or retract through the action of an internal motor and a gearbox. This structure has been widely used in the prior art. In the present invention, it is only used to drive the stamping assembly 53 to lift, and its internal structure, operating principle, wiring, and control method will not be elaborated herein;

[0055] The second limiting rods 52 arranged on both sides of the electric telescopic rod 51 are used to limit the descending trajectory of the stamping assembly 53 and prevent position deviation during the descending process.

[0056] The electric telescopic rod 51 drives the stamping assembly 53 and the pressing plate 55 to descend. By the cooperation of the supporting assembly 54 and the pressing plate 55, the material is smoothly placed on the upper part of the supporting assembly 54, and through the cooperation of the pressing block 535 and the shaping component 536, it is fixed and stamped and shaped to form a predetermined bottom plate shape, realizing the shaping process of the bottom plate.

[0057] Furthermore, to achieve the stamping and shaping of the steel plate to be stamped into a predetermined shape, refer to Figure 8 and Figure 9 , the stamping assembly 53 includes an I-shaped connecting plate 531 fixedly connected to the lower ends of the electric telescopic rod 51 and the second limiting rods 52, and a pressing block 535 located below the I-shaped connecting plate 531. Four first compression springs 533 are fixedly connected to the lower end of the I-shaped connecting plate 531 in a rectangular distribution. Four third limiting rods 532 penetrating through the upper end of the I-shaped connecting plate 531 and extending to the lower end of the I-shaped connecting plate 531 are arranged at the upper end of the I-shaped connecting plate 531. The lower ends of two third limiting rods 532 and two first compression springs 533 on the same side are jointly fixedly connected to a shaping component 536. Both shaping components 536 are slidably connected to the pressing block 535 through spring blocks. Piston rods 534 slidably connected to adjacent shaping components 536 are fixedly connected to the lower end of the I-shaped connecting plate 531 in a rectangular distribution; the supporting assembly 54 includes a support table 541 fixedly connected to the bottom wall of the inner cavity of the machine tool housing 1.

[0058] During the descending process of the electric telescopic rod 51, it will first drive the shaping component 536 to descend through the I-shaped connecting plate 531 and the first compression springs 533. Synchronously, under the action of the spring blocks, the shaping component 536 will drive the pressing block 535 to descend synchronously and make it smoothly contact the material. At this time, the spring blocks are compressed, and the pressing block 535 stops moving. The shaping component 536 will continue to descend under the action of the I-shaped connecting plate 531 and the first compression springs 533 until the material fits the shape of the support table 541, thereby completing the precise stamping of the material.

[0059] Embodiment 4. On the basis of Embodiment 3, this embodiment uses the cooperation between the first piston rod 534 installed at the lower part of the I-shaped connecting plate 531 and the hydraulic cavity 5365 to drive the sliding plate 5362 to move downward in the trapezoidal block 5361, and push out the punch 5364 so that it enters the die hole 544. During this process, the punch 5364 is used to cut the installation hole of the bottom plate, realizing synchronous processing of shaping and hole opening, improving the processing efficiency, ensuring the accuracy and position accuracy of the bottom plate installation hole at the same time, meeting the subsequent assembly requirements, and realizing multi-process integration through optimized structural design, further improving the production efficiency and reducing the cost.

[0060] Specifically, to cooperate with the shaping component 536 to punch the raw material of the bottom plate, refer to Figure 9 and Figure 10 , a number of die holes 544 corresponding to the position of the punch 5364 and penetrating up and down are arranged in an array on both the left and right sides of the upper end of the support table 541. A waste box 543 is slidably connected to the lower end of the machine tool housing 1. A blanking component 542 symmetrically distributed front and back is arranged between the lower end of the support table 541 and the inner cavity of the machine tool housing 1.

[0061] When the material is just sent into the feeding structure 2, it will be suspended above the support table 541 under the action of the blanking component 542. During the downward movement of the stamping component 53, the pressing plate 55 and the blanking component 542 cooperate to drive the blanking component 542 to descend. At this time, the material will adhere to the upper part of the support table 541 and be clamped between the pressing block 535 and the support table 541 to fix the material and prevent the material from shifting during the stamping and shaping process.

[0062] Furthermore, to further punch the bottom plate after stamping and realize multiple combined processing, refer to Figure 8 , the shaping component 536 includes a trapezoidal block 5361 slidably connected to the pressing block 535 through a spring block. A sliding plate 5362 is slidably connected to the inner surface of the trapezoidal block 5361. A number of punches 5364 are fixedly connected to the lower end of the sliding plate 5362 in an array. A second compression spring 5363 fixedly connected to the bottom wall of the inner cavity of the trapezoidal block 5361 is fixedly connected to the part between adjacent two punches 5364 at the lower end of the sliding plate 5362.

[0063] Furthermore, to separate the bottom plate after shaping and punching from the limiting groove 241 to facilitate the subsequent blanking of the guiding component 24, refer to Figure 8, five hydraulic chambers 5365 are provided on the upper side of the inner cavity of the trapezoidal block 5361. The inner surfaces of the two hydraulic chambers 5365 located below the first piston rod 534 are both slidably connected to the outer surface of the adjacent first piston rod 534, and connecting pipes 5367 communicating with the adjacent hydraulic chambers 5365 are provided on both the left and right sides. Three second piston rods 5366 slidably connected to the inner surface of the adjacent hydraulic chamber 5365 are fixedly connected to the upper end of the sliding plate 5362 in an array distribution.

[0064] When the trapezoidal block 5361 descends following the I-shaped connecting plate 531, the trapezoidal block 5361 will first cooperate with the support table 541 to stamp and shape the material. Subsequently, when the trapezoidal block 5361 reaches a predetermined height, it stops moving. At this time, the sliding plate 5362, the bottom plate, and the support table 541 are successively attached together. Then, the electric telescopic rod 51 drives the I-shaped connecting plate 531 to continue descending. At this time, the first compression spring 533 is compressed under force, and the first piston rod 534 is pressed into the two hydraulic chambers 5365. The hydraulic oil in these two hydraulic chambers 5365 will enter the hydraulic chambers 5365 where the three second piston rods 5366 are located through the connecting pipes 5367, and press the second piston rods 5366 to slide downward. At this time, the second piston rods 5366 drive the sliding plate 5362 to move downward, and finally push the punch 5364 out of the trapezoidal block 5361, so that it penetrates the base and enters the die hole 544. The punched metal waste enters the waste box 543 for temporary storage.

[0065] When the electric telescopic rod 51 rises, the first compression spring 533 slowly resets. At this time, the first piston rod 534 rises from the hydraulic chamber 5365, and the hydraulic oil returns to balance. Under the action of the second compression spring 5363, the first compression spring 533, and the spring block, the punch 5364, the trapezoidal block 5361, and the pressing block 535 are reset to their initial positions in sequence.

[0066] Further, in order to separate the bottom plate from the support table 541 after the shaping is completed to facilitate the taking of the finished product, refer to Figure 10 , the blanking component 542 includes a support plate 5422 slidably connected to the inner surface of the machine tool housing 1. The upper ends of the support plate 5422 are symmetrically and fixedly connected with sliding columns 5423 on the left and right. Both of the two sliding columns 5423 penetrate the lower end of the support table 541 and extend to the upper end of the support table 541 and are fixedly connected with magnetic plates 5424. The upper ends of the support plate 5422 are symmetrically and fixedly connected with third compression springs 5425 fixedly connected to the lower end of the support table 541 on the left and right. The upper ends of the support plate 5422 are symmetrically and fixedly connected with U-shaped plates 5421 on the left and right. The U-shaped plates 5421 are located below the adjacent pressing plates 55.

[0067] After shaping, the base is no longer flat and will adsorb on the support platform 541. After the pressing plate 55 leaves the U-shaped plate 5421, the third compression spring 5425 will reset and pull the support plate 5422 closer to the support platform 541. At this time, the bottom plate can be lifted by the sliding column 5423 and the magnetic plate 5424 to separate it from the support platform 541, facilitating the subsequent guiding component 24 to drive the U-shaped bracket 23 and the electromagnet 22 to pick up materials.
