Description

Technical Field

[0001] This invention relates to the field of forklift processing equipment, and more specifically, to an integrated stamping forming equipment and method for forklift shells. Background Technology

[0002] Forklifts are industrial handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. The International Organization for Standardization (ISO) refers to them as industrial vehicles. They are commonly used for transporting large items in warehouses and are typically powered by internal combustion engines or batteries. Parts of the forklift's body are formed by stamping, such as the rear panel.

[0003] Some existing stamping devices lack a correction structure. After the raw material is placed on top of the mold using existing technology, it may shift due to vibration or shaking, potentially causing deviations during product stamping and affecting the processing quality of the forklift shell. Therefore, the raw material may require multiple manual adjustments after being placed on the worktable, reducing the processing efficiency of the equipment and decreasing adjustment accuracy. To address these issues, we propose an integrated stamping forming device and method for forklift shells. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an integrated stamping forming device and method for forklift shells, employing the following technical solution: An integrated stamping forming equipment for forklift shells includes a base, with mounting seats fixedly installed on both sides of the base, mounting frames fixedly installed on the top of each of the two mounting seats, and conveyor belts provided inside each of the two mounting frames. A robotic arm is provided on the top of each of the two mounting seats near the base, and an adsorption component is provided at the end of each of the two robotic arms. The base has a lower mold at its top, and the lower mold has a cavity at its top. The base has a top plate above it, and four symmetrically distributed columns are provided between the top plate and the base. The top plate has an upper mold below it. A first cylinder is fixedly installed at the top of the top plate, and the piston shaft of the first cylinder slides through the top plate and is fixedly connected to the top of the upper mold. The base has an installation groove inside it, and a correction assembly is provided between the base and the lower mold. An ejection assembly is provided inside the mold cavity.

[0005] By adopting the above technical solution, when using this equipment, the operator places the raw material plate on one of the conveyor belts. The conveyor belt transports the raw material plate towards the lower mold. Then, a robotic arm installed on the same side drives a set of adsorption components to move above the raw material plate. The adsorption components adsorb the raw material plate, thus clamping it. The robotic arm then transports the raw material plate above the lower mold. Once the raw material plate is above the lower mold, a correction component adjusts its position at the top of the lower mold, facilitating precise subsequent processing without manual adjustment, thus improving processing efficiency. After the first section is completed, the upper mold is driven to move downward by the first cylinder. The contact between the upper and lower molds can achieve the function of stamping products. After the product is processed, the upper mold is driven to rise by the first cylinder to disengage from the lower mold. The ejection component ejects the product from the mold cavity, which can achieve the function of demolding. Subsequently, another robotic arm drives the same set of adsorption components to move above the product. The adsorption components adsorb the product, which can achieve the function of picking up the material. The robotic arm moves the product to another conveyor belt for conveying away. The setting of two sets of robotic arms and adsorption components enables the equipment to have the function of automatic loading and unloading, which helps to improve the processing efficiency of the equipment.

[0006] Furthermore, the adsorption assembly includes a mounting plate at the end of the robotic arm. Each of the two mounting plates has two sets of symmetrically distributed suction cups at its bottom. Each set of suction cups consists of two suction cups. A vacuum pump is fixedly mounted on the top of each of the two mounting plates. Each of the two vacuum pumps has a first double-connector on its top. A second double-connector is provided between the tops of the two suction cups in the same set. A conduit is connected between the tops of the two second double-connectors in the same set and the first double-connector in the same set.

[0007] By adopting the above technical solution, negative pressure is generated by the operation of a vacuum pump. The negative pressure acts on the suction cup through the first double-connector, the conduit, and the second double-connector. The suction cup adsorbs the raw material board or the processed product, thus achieving the function of clamping the raw material board or the product.

[0008] Furthermore, the correction assembly includes a reduction motor fixedly installed on the inner wall of the bottom end of the mounting groove. A drive gear is fixedly sleeved on the side wall of the output shaft of the reduction motor. The base has movable grooves on all four sides, and movable blocks are slidably installed in each movable groove. Screws are rotatably installed on the inner wall of the movable groove away from the movable blocks in the same group. The movable blocks are sleeved on the side walls of the screws in the same group. The end of the screws away from the movable blocks in the same group rotatably passes through the mounting groove. A driven gear is fixedly sleeved on the side wall of the end of the four screws that passes through the mounting groove. The four driven gears mesh with the drive gear. A connecting block is fixedly installed on the top of the end of the four movable blocks away from the base. A first correction plate is provided on the side of the four connecting blocks near the lower mold. A groove is opened on the top of each first correction plate, and a second correction plate is slidably installed in each groove. Multiple second springs arranged in a linear array are fixedly connected between the second correction plates and the inner wall of the bottom end of the grooves in the same group. A telescopic assembly is provided between the connecting blocks and the first correction plates in the same group.

[0009] By adopting the above technical solution, after the raw material plate is placed above the lower mold, the drive gear is driven to rotate by the reduction motor. The drive gear drives four driven gears to rotate synchronously, and the driven gears drive the screws in the same group to rotate. This drives the moving block to slide in the same group of moving slots. The moving block, along with the connecting block, the first correction plate, and the second correction plate, moves synchronously towards the lower mold. By contacting the opposite side of the second correction plate and the raw material plate, the cooperation of the four second correction plates can correct the position of the raw material plate, which helps to maintain the accuracy of the placement of the raw material plate and thus improves the processing quality of the product. Furthermore, the first correction plate and the connecting block in the same group are connected by a telescopic component, which allows for a telescopic distance between them, making it easier for the equipment to correct and clamp raw material plates of different sizes.

[0010] Furthermore, a first limiting block is fixedly installed on both sides of the moving block near the end of the reduction motor, and a first limiting groove matching the first limiting block in the same group is opened on the inner wall of the moving groove. A second limiting block is fixedly installed on both sides of the lower section of the second correction plate, and a second limiting groove matching the second limiting block in the same group is opened on the inner wall of the groove.

[0011] By adopting the above technical solution, when the moving block slides in the same group of moving grooves, the moving block, along with the first limiting block, slides in the same side of the first limiting groove. The cooperation between the first limiting block and the second limiting groove helps to maintain the stability of the sliding of the moving block and helps to prevent the moving block from leaving the moving groove. When the second correction plate slides in the same group of grooves, the second correction plate, along with the second limiting block, slides in the same side of the second limiting groove. The cooperation between the second limiting block and the limiting groove helps to maintain the stability of the sliding of the second correction plate and helps to prevent the second correction plate from leaving the groove.

[0012] Furthermore, each of the screws is rotatably fitted with a stabilizing block on one side wall of the mounting groove, and the top of each stabilizing block is fixedly connected to the inner wall of the top of the mounting groove.

[0013] By adopting the above technical solution, the screw sidewall is supported and stabilized by the setting of the stabilizing block, and the top of the stabilizing block is fixedly connected to the inner wall of the top of the mounting groove.

[0014] Furthermore, the telescopic assembly includes a support column fixedly installed on the connecting block near the lower mold side. Each support column near the lower mold side has a movable groove, and a support rod is slidably installed in each movable groove. Each support rod near the lower mold side is fixedly connected to the side opposite to the first correction plate in the same group. Each support rod away from the lower mold side has a first spring fixedly connected to the inner wall of the side opposite to the movable groove in the same group.

[0015] By adopting the above technical solution, when the second correction plate comes into contact with the raw material plate, the moving block is continuously driven to move by the operation of the reduction motor. The second correction plate pushes the support rod to slide in the same group of movable slots, and the support rod pushes the first spring of the same group to retract. Through the cooperation of the support rod, the first spring and the support column, the distance between the second correction plate and the connecting block of the same group can be adjusted, thereby facilitating the equipment to clamp and correct raw material plates of different sizes.

[0016] Furthermore, sliders are fixedly installed on both sides of the support rod away from the lower mold, and the inner wall of the movable groove is provided with a groove that matches the slider on the same side.

[0017] By adopting the above technical solution, when the support rod slides in the same group of movable grooves, the support rod slides in the same side groove along with the slider. The cooperation between the slider and the groove helps to maintain the stability of the support rod sliding and helps to prevent the support rod from leaving the movable groove.

[0018] Furthermore, the ejection assembly includes an ejection plate disposed within the mold cavity, and the inner wall of the base has four symmetrically distributed storage slots, and each of the four storage slots has a second cylinder fixedly installed therein. The piston shafts of the four second cylinders slide through into the mold cavity, and the ends of the piston shafts of the four second cylinders are fixedly connected to the bottom end of the ejection plate. The inner wall of the bottom end of the mold cavity has an ejection groove that matches the ejection plate.

[0019] By adopting the above technical solution, after the product is processed, the first cylinder drives the upper mold to rise and disengage from the lower mold. Then, the second cylinder drives the ejector plate to rise, and the ejector plate ejects the processed product out of the mold cavity, which can play the role of demolding and facilitate the subsequent material handling of the equipment.

[0020] Furthermore, two symmetrically distributed support blocks are fixedly installed on both sides of the upper mold, and four symmetrically distributed limiting rods are fixedly installed between the base and the top plate. The support blocks are slidably sleeved on the side wall of the limiting rods in the same group.

[0021] By adopting the above technical solution, when the upper mold is raised or lowered, the upper mold, along with the support block, slides on the same set of limit rods. The cooperation between the support block and the limit rods helps to avoid the phenomenon of displacement when the upper mold is raised or lowered, and also helps to maintain the stability of the upper mold raising and lowering.

[0022] A method for integral stamping forming of a forklift shell includes the following steps: S1. Loading and unloading steps: During product processing, the raw material plate is placed on one of the conveyor belts and transported towards the lower mold. Then, a robotic arm installed on the same side drives the same set of adsorption components to move above the raw material plate. The adsorption components adsorb the raw material plate, thus clamping it. The robotic arm then transports the raw material plate to the upper mold. After the product is processed, another robotic arm drives the adsorption components to adsorb and clamp the product, moving it to the upper part of another conveyor belt. The processed product is then transported away by the conveyor belt, thus unloading the material. The setup of two sets of robotic arms and adsorption components enables the equipment to automatically load and unload, which helps improve the processing efficiency of the equipment. S2. Correction Steps: After the raw material plate is placed above the lower mold, the drive gear is driven to rotate by the reduction motor. The drive gear drives four driven gears to rotate synchronously. The driven gears drive the screws in the same group to rotate, thereby driving the moving block to slide in the same group of moving slots. The moving block, along with the connecting block, the first correction plate, and the second correction plate, moves synchronously towards the lower mold. By contacting the opposite side of the second correction plate and the raw material plate, the cooperation of the four second correction plates can correct the position of the raw material plate, which helps to maintain the accuracy of the placement of the raw material plate and thus improves the processing quality of the product. In addition, the first correction plate and the connecting block in the same group are connected by a telescopic component, which allows for telescopic distance between the first correction plate and the connecting block in the same group, making it easier for the equipment to correct and clamp raw material plates of different sizes. S3. Stamping Step: After the raw material plate is corrected, the upper die is driven to move down by the first cylinder, and the upper die, with the support block, slides on the same group of limit rods. The cooperation of the support block and the limit rods helps to avoid the phenomenon of displacement when the upper die is raised and lowered, and helps to maintain the stability of the upper die raising and lowering. The upper die and the lower die are in contact to stamp the product. When the upper die and the lower die are in contact, the upper die pushes the second correction plate to slide in the same group of grooves, so that the top of the second correction plate is lower than the height of the lower die, which facilitates the precise contact of the upper die and the lower die. After the product is processed, the first cylinder drives the upper die to rise and disengage from the lower die. Then the second correction plate returns to its original position under the elastic force of the second spring in the same group, which facilitates the subsequent correction of the raw material plate. S4 Demolding Step: After the product is processed, the first cylinder drives the upper mold to rise and separate from the lower mold. Then, the second cylinder drives the ejector plate to rise, and the ejector plate ejects the processed product out of the mold cavity, which can play the role of demolding and facilitate the subsequent material handling of the equipment.

[0023] In summary, the present invention has the following beneficial technical effects: (1) In this invention, by setting the correction component, the drive reduction motor drives the moving block to move the first correction plate and the second correction plate synchronously, so that the second correction plate contacts the opposite side of the raw material plate, which can play the role of correcting the raw material plate, which facilitates the subsequent precise processing of the equipment, without the need for manual adjustment, and helps to improve the processing efficiency of the equipment.

[0024] (2) In this invention, the connecting block and the second correction plate in the same group are connected by a telescopic component. When the second correction plate comes into contact with the raw material plate, the moving block is continuously driven to move by the operation of the deceleration motor. The second correction plate pushes the support rod to slide in the movable groove in the same group, and the support rod pushes the first spring in the same group to retract. Through the cooperation of the support rod, the first spring and the support column, the distance between the second correction plate and the connecting block in the same group can be adjusted, thereby facilitating the equipment to clamp and correct raw material plates of different sizes.

[0025] (3) In this invention, the setup of two sets of robotic arms and adsorption components facilitates the automatic loading and unloading of materials, thereby improving the processing efficiency of the equipment. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0032] Please see Figure 1-7 An integrated stamping forming equipment for forklift shells includes a base 1, with mounting seats 6 fixedly installed on both sides of the base 1. Mounting frames 7 are fixedly installed on the top of each mounting seat 6, and conveyor belts 8 are provided inside each mounting frame 7. A robotic arm 18 is provided on the top of each mounting seat 6 near the base 1, and an adsorption assembly is provided at the end of each robotic arm 18. The adsorption assembly includes a mounting plate 10 located at the end of the robotic arm 18. Two sets of symmetrically distributed suction cups 9 are provided at the bottom of each mounting plate 10, with two suction cups 9 in each set. A vacuum pump 11 is fixedly installed on the top of each mounting plate 10, and a first double-connector 20 is provided on the top of each vacuum pump 11. A second double-connector 21 is provided between the tops of the two suction cups 9 in the same set. A conduit 19 connects the tops of the two second double-connectors 21 and the first double-connector 20 in the same set.

[0033] During product processing, the raw material plate is placed on one of the conveyor belts 8, which transport the raw material plate towards the lower mold 2. Then, the robotic arm 18 installed on the same side drives the same group of adsorption components to move above the raw material plate. The vacuum pump 11 generates negative pressure, which acts on the suction cup 9 through the first double-connector 20, the conduit 19, and the second double-connector 21. The suction cup 9 adsorbs the raw material plate or the processed product, thus clamping the raw material plate or the product. Then, the robotic arm 18 transports the raw material plate to the upper mold 2. After the product is processed, the other robotic arm 18 drives the adsorption components to adsorb and clamp the product, moving the product to the upper conveyor belt 8. The conveyor belt 8 then transports the processed product away, thus unloading the material. The arrangement of two sets of robotic arms 18 and adsorption components enables the equipment to have automatic loading and unloading functions, which helps to improve the processing efficiency of the equipment.

[0034] The base 1 has a lower mold 2 at its top, and a mold cavity is formed at the top of the lower mold 2. A top plate 26 is located above the base 1. Four symmetrically distributed columns 5 are located between the top plate 26 and the base 1. An upper mold 14 is located below the top plate 26. A first cylinder 15 is fixedly installed at the top of the top plate 26, and the piston shaft of the first cylinder 15 slides through the top plate 26 and is fixedly connected to the top of the upper mold 14. An installation groove 27 is provided inside the base 1. A correction assembly is provided between the base 1 and the lower mold 2. The correction assembly includes a reduction motor 28 fixedly installed on the inner wall of the bottom end of the installation groove 27. A drive gear 29 is fixedly sleeved on the side wall of the output shaft of the reduction motor 28. Moving grooves 31 are provided on all four sides of the base 1. Moving blocks 23 are slidably installed in each moving groove 31. The moving grooves 31 are located away from the moving blocks in the same group. Each of the four moving blocks 23 has a screw 32 rotatably mounted on the inner wall of one side. Each of the moving blocks 23 is sleeved on the side wall of the screw 32 in the same group. The end of the screw 32 away from the moving block 23 in the same group rotates through to the mounting groove 27. Each of the four screw 32 has a driven gear 30 fixedly mounted on the side wall of the end of the mounting groove 27. Each of the four driven gears 30 meshes with the drive gear 29. Each of the four moving blocks 23 has a connecting block 22 fixedly mounted on the top of the end away from the base 1. Each of the four connecting blocks 22 has a first correction plate 3 on the side near the lower mold 2. Each of the first correction plates 3 has a groove 35 at the top. Each of the grooves 35 has a second correction plate 4 slidably mounted in the groove. Multiple second springs 36 arranged in a linear array are fixedly connected between the second correction plate 4 and the inner wall of the bottom end of the groove 35 in the same group.

[0035] After the raw material plate is placed above the lower mold 2, the drive gear 29 is driven to rotate by the reduction motor 28. The drive gear 29 drives four driven gears 30 to rotate synchronously. The driven gears 30 drive the screw 32 in the same group to rotate, thereby driving the moving block 23 to slide in the moving groove 31 in the same group. The moving block 23, along with the connecting block 22, the first correction plate 3 and the second correction plate 4, moves synchronously towards the lower mold 2. By contacting the opposite side of the second correction plate 4 and the raw material plate, the cooperation of the four second correction plates 4 can correct the position of the raw material plate, which helps to maintain the accuracy of the placement of the raw material plate and thus improves the processing quality of the product.

[0036] The movable block 23 has first limiting blocks fixedly installed on both sides of the end near the reduction motor 28. The inner wall of the movable groove 31 is provided with first limiting grooves that match the first limiting blocks in the same group. The lower section of the second correction plate 4 has second limiting blocks fixedly installed on both sides. The inner wall of the groove 35 is provided with second limiting grooves that match the second limiting blocks in the same group. When the movable block 23 slides in the movable groove 31 of the same group, the movable block 23 slides with the first limiting blocks in the first limiting grooves on the same side. The cooperation of the first limiting blocks and the second limiting grooves helps to maintain the stability of the sliding of the movable block 23 and helps to prevent the movable block 23 from detaching from the movable groove. When the second correction plate 4 slides within the same group of grooves 35, the second correction plate 4, along with the second limiting block, slides within the same side of the second limiting groove. The cooperation between the second limiting block and the limiting groove helps maintain the stability of the sliding of the second correction plate 4 and helps prevent the second correction plate 4 from detaching from the groove 35. The screw 32 passes through the side wall of one end of the mounting groove 27 and is rotatably fitted with a stabilizing block. The top of the stabilizing block is fixedly connected to the inner wall of the top of the mounting groove 27. The side wall of the screw 32, through the setting of the stabilizing block and the fixed connection between the top of the stabilizing block and the inner wall of the top of the mounting groove 27, can play the role of supporting and stabilizing the screw 32.

[0037] Telescopic components are provided between the connecting block 22 and the first correction plate 3. The telescopic components include a support column 24 fixedly installed on the side of the connecting block 22 near the lower mold 2. Each support column 24 near the lower mold 2 has a movable groove 33. Each movable groove 33 has a support rod 25 slidably installed in the support rod 25. Each support rod 25 near the lower mold 2 is fixedly connected to the side of the first correction plate 3 in the same group. Each support rod 25 away from the lower mold 2 has a first spring 34 fixedly connected to the inner wall of the side of the support rod 25 opposite to the movable groove 33 in the same group. When the second correction plate 4 contacts the raw material plate, the moving block 23 is continuously driven to move by the operation of the reduction motor 28. The second correction plate 4 pushes the support rod 25 to slide in the movable groove 33 in the same group, and the support rod 25 pushes the first spring 34 in the same group to retract. Through the cooperation of the support rod 25, the first spring 34 and the support column 24, the distance between the second correction plate 4 and the connecting block 22 in the same group can be adjusted, thereby facilitating the equipment to clamp and correct raw material plates of different sizes.

[0038] The support rod 25 is fixedly mounted with sliders on both sides of the end away from the lower mold 2. The inner wall of the movable groove 33 is provided with a sliding groove that matches the slider on the same side. When the support rod 25 slides in the same movable groove 33, the support rod 25 slides with the slider in the sliding groove on the same side. The cooperation between the slider and the sliding groove helps to maintain the stability of the sliding of the support rod 25 and helps to prevent the support rod 25 from falling out of the movable groove 33.

[0039] Two symmetrically distributed support blocks 13 are fixedly installed on both sides of the upper mold 14. Four symmetrically distributed limiting rods 12 are fixedly installed between the base 1 and the top plate 26. The support blocks 13 are slidably sleeved on the side walls of the same group of limiting rods 12. After the raw material plate is corrected, the upper mold 14 is driven to move down by the first cylinder 15, and the upper mold 14, with the support blocks 13, slides on the same group of limiting rods 12. The cooperation between the support blocks 13 and the limiting rods 12 helps to avoid the phenomenon of displacement when the upper mold 14 is raised and lowered, and helps to maintain the stability of the upper mold 14 during raising and lowering. Qualitatively, the upper mold 14 and the lower mold 2 are fitted together to form a stamping product. When the upper mold 14 and the lower mold 2 are fitted together, the upper mold 14 pushes the second correction plate 4 to slide within the groove 35 of the same group, so that the top of the second correction plate 4 is lower than the height of the lower mold 2, which facilitates the precise fitting of the upper mold 14 and the lower mold 2. After the product is processed, the first cylinder 15 drives the upper mold 14 to rise and disengage from the lower mold 2. Then, the second correction plate 4 returns to its original position under the elastic force of the second spring 36 of the same group, which facilitates the subsequent re-correction of the raw material plate.

[0040] The mold cavity is equipped with an ejection assembly, which includes an ejection plate 16 disposed within the mold cavity. The inner wall of the base 1 has four symmetrically distributed receiving slots 37, and each of the four receiving slots 37 has a second cylinder 17 fixedly installed in it. The piston shafts of the four second cylinders 17 slide through the mold cavity, and the ends of the piston shafts of the four second cylinders 17 are fixedly connected to the bottom end of the ejection plate 16. The inner wall at the bottom end of the mold cavity has an ejection groove that matches the ejection plate 16. After the product is processed, the first cylinder 15 drives the upper mold 14 to rise and disengage from the lower mold 2. Then, the second cylinder 17 drives the ejection plate 16 to rise, and the processed product is ejected from the mold cavity through the ejection plate 16, which can play the role of demolding and facilitate subsequent material handling by the equipment.

[0041] A method for integral stamping forming of a forklift shell includes the following steps: S1. Loading and unloading steps: During product processing, the raw material plate is placed on one of the conveyor belts 8. The conveyor belt 8 transports the raw material plate towards the lower mold 2. Then, the robotic arm 18 installed on the same side drives the same group of adsorption components to move above the raw material plate. The adsorption components adsorb the raw material plate, thus clamping it. The robotic arm 18 then transports the raw material plate above the lower mold 2. After the product is processed, the other robotic arm 18 drives the adsorption components to adsorb and clamp the product, moving it above another conveyor belt 8. The conveyor belt 8 then transports the processed product away, thus unloading it. The setup of two sets of robotic arms 18 and adsorption components enables the equipment to have automatic loading and unloading functions, which helps improve the processing efficiency of the equipment. S2. Correction Steps: After the raw material plate is placed above the lower mold 2, the drive gear 29 is driven to rotate by the reduction motor 28. The drive gear 29 drives four driven gears 30 to rotate synchronously. The driven gears 30 drive the screw 32 in the same group to rotate, thereby driving the moving block 23 to slide in the moving groove 31 in the same group. The moving block 23, along with the connecting block 22, the first correction plate 3, and the second correction plate 4, moves synchronously towards the lower mold 2. The second correction plate 4 contacts the opposite side of the raw material plate. Through the cooperation of the four second correction plates 4, the position of the raw material plate can be corrected, which helps to maintain the accuracy of the placement of the raw material plate and thus improves the processing quality of the product. Furthermore, the first correction plate 3 and the connecting block 22 in the same group are connected by a telescopic component, which allows for a telescopic distance between the first correction plate 3 and the connecting block 22 in the same group, thus facilitating the equipment to correct and clamp raw material plates of different sizes. S3, Stamping Step: After the raw material plate is corrected, the upper die 14 is driven to move down by the first cylinder 15, and the upper die 14, with the support block 13, slides on the same group of limit rods 12. The cooperation of the support block 13 and the limit rods 12 helps to avoid the phenomenon of displacement when the upper die 14 is raised and lowered, and helps to maintain the stability of the upper die 14. The upper die 14 and the lower die 2 are in contact to stamp the product. When the upper die 14 and the lower die 2 are in contact, the upper die 14 pushes the second correction plate 4 to slide in the same group of grooves 35, so that the top of the second correction plate 4 is lower than the height of the lower die 2, which facilitates the precise contact of the upper die 14 and the lower die 2. After the product is processed, the first cylinder 15 drives the upper die 14 to rise and disengage from the lower die 2. Then the second correction plate 4 returns to its original position under the elastic force of the same group of second springs 36, which facilitates the subsequent correction of the raw material plate. S4 Demolding Step: After the product is processed, the first cylinder 15 drives the upper mold 14 to rise and disengage from the lower mold 2. Then, the second cylinder 17 drives the ejector plate 16 to rise, and the ejector plate 16 ejects the processed product out of the mold cavity, which can play the role of demolding and facilitate the subsequent material handling of the equipment.

[0042] The implementation principle of this invention is as follows: When using the equipment, the operator places the raw material plate on one of the conveyor belts 8. The conveyor belt 8 transports the raw material plate towards the lower mold 2. Then, the robotic arm 18 installed on the same side drives the adsorption assembly to move above the raw material plate. The adsorption assembly adsorbs the raw material plate, thus clamping it. Subsequently, the robotic arm 18 transports the raw material plate above the lower mold 2. Once the raw material plate is above the lower mold 2, the alignment assembly aligns the position of the raw material plate at the top of the lower mold 2, facilitating subsequent precise processing without manual adjustment, thus improving the processing efficiency of the equipment. Once the product position adjustment is complete... Then, the upper mold 14 is driven to move down by the first cylinder 15. The upper mold 14 and the lower mold 2 are joined together to stamp the product. After the product is processed, the upper mold 14 is driven to rise by the first cylinder 15 to disengage from the lower mold 2. The product is ejected from the mold cavity by the ejection component, which can achieve the demolding function. Subsequently, another robotic arm 18 drives the same set of adsorption components to move above the product. The adsorption components adsorb the product, which can achieve the material picking function. The robotic arm 18 moves the product to the top of another conveyor belt 8 for conveying away. The setting of two sets of robotic arms 18 and adsorption components enables the equipment to have automatic loading and unloading functions, which helps to improve the processing efficiency of the equipment.

Loading and unloading steps: When processing the product, the raw material plate is placed on one of the conveyor belts (8). The raw material plate is transported to the lower mold (2) by the conveyor belt (8). Then, the same group of adsorption components is driven by the robotic arm (18) installed on the same side to move to the top of the raw material plate. The adsorption components adsorb the raw material plate, which can play the role of clamping the raw material plate. Then, the robotic arm (18) transports the raw material plate to the top of the lower mold (2). When the product is processed, the adsorption components are driven by another robotic arm (18) to adsorb and clamp the product, and move the product to the top of another conveyor belt (8). The processed product is transported away by the conveyor belt (8), which can play the role of unloading. With the setting of two sets of robotic arms (18) and adsorption components, the equipment has the function of automatic loading and unloading, which is conducive to improving the processing efficiency of the equipment. S2, Correction steps: After the raw material plate is placed above the lower mold (2), the drive gear (29) is driven to rotate by the reduction motor (28). The drive gear (29) drives the four driven gears (30) to rotate synchronously. The driven gears (30) drive the screw (32) of the same group to rotate, thereby driving the moving block (23) to slide in the moving groove (31) of the same group. The moving block (23) moves synchronously with the connecting block (22), the first correction plate (3) and the second correction plate (4) towards the lower mold (2). The second correction plate (4) contacts the opposite side of the raw material plate. Through the cooperation of the four second correction plates (4), the position of the raw material plate can be corrected, which is conducive to maintaining the accuracy of the placement of the raw material plate and thus improving the processing quality of the product. The first correction plate (3) and the connecting block (22) of the same group are connected by a telescopic component, so that there is a telescopic distance between the first correction plate (3) and the connecting block (22) of the same group, which makes it easier for the equipment to correct and clamp raw material plates of different sizes. S3, Stamping Steps: After the raw material plate is corrected, the upper die (14) is driven to move down by the first cylinder (15), and the upper die (14) slides on the same set of limit rods (12) with the support block (13). The cooperation between the support block (13) and the limit rod (12) helps to avoid the phenomenon of displacement when the upper die (14) rises and falls, and helps to maintain the stability of the upper die (14) rising and falling. Through the fit between the upper die (14) and the lower die (2), the stamping product can be stamped. When the upper die (14) is in contact with the lower die (2), the stamping product can be stamped. 4) When the upper mold (14) is in contact with the lower mold (2), the upper mold (14) pushes the second correction plate (4) to slide in the same group groove (35), so that the top of the second correction plate (4) is lower than the height of the lower mold (2), which makes it easy for the upper mold (14) and the lower mold (2) to fit together accurately. After the product is processed, the first cylinder (15) drives the upper mold (14) to rise and separate from the lower mold (2). Then the second correction plate (4) returns to its original position under the elastic force of the second spring (36) in the same group, which makes it easy to correct the raw material plate again in the future. S4. Demolding step: After the product is processed, the first cylinder (15) drives the upper mold (14) to rise and separate from the lower mold (2). Then, the second cylinder (17) drives the ejector plate (16) to rise. The ejector plate (16) ejects the processed product out of the mold cavity, which can play the role of demolding and facilitate the subsequent material removal of the equipment.
