Description

Technical Field

[0001] The present invention relates to the technical field of part stamping, and particularly to a stamping forming device and a forming method for new energy vehicle parts. Background Art

[0002] In the current field of automobile manufacturing, especially in the production of new energy vehicle parts, the stamping forming process plays a crucial role. However, with the rapid development of the industry and the continuous improvement of the market's requirements for the production volume and quality of new energy vehicles, the existing stamping forming efficiency of automobile parts has gradually become difficult to meet the actual production needs. For example, traditional stamping forming equipment has a slow feeding speed and requires a large amount of manual intervention in operation, resulting in a long time-consuming feeding process; there is a lack of precise positioning and efficient transfer mechanisms during the material conveying process, which easily leads to problems such as untimely material supply and poor connection; the mold replacement is inconvenient. When producing parts of different models and specifications, the cumbersome process of replacing the mold will greatly delay the production time, thereby affecting the overall stamping forming efficiency.

[0003] In view of the above problems, the present invention proposes a stamping forming device and a forming method for new energy vehicle parts. Summary of the Invention

A plurality of balls are embedded in the auxiliary plate in an array, and the surfaces of the balls are slidably connected to the lower surface of the material to be formed.

[0013] Preferably, the feeding mechanism includes a material box. Springs are arranged in an array on the inner bottom wall of the material box, and a support plate is fixedly connected to the upper ends of the springs. The material to be formed is placed in the material box. Cylinders II are fixedly connected to both side surfaces of the material box respectively. A push rod is fixedly connected to the piston rod of the cylinder II, and the surface of the push rod is in contact with one side surface of the material to be formed. Rotating grooves are symmetrically formed at the upper end of the material box. A block with an arc-shaped surface on one side is rotatably connected to the inner wall of each rotating groove. A torsion spring is fixedly connected to one side of the block, and one end of the torsion spring is fixedly connected to the inner wall of the rotating groove. Motors are respectively arranged at opposite corners at the upper end of the material box, and the surfaces of the motors are fixedly connected to the body of the material box. A spur gear I is fixedly connected to the output shaft of the motor. Spur gears II are respectively engaged with both sides of the spur gear I.

A guide wheel is arranged above the bearing, and the lower end of the guide wheel is fixedly connected to the inner ring of the bearing through a connecting rod. The lower end of the connecting rod is fixedly connected to the upper end of the spur gear II.

[0014] Preferably, the guide wheels are made of rubber, and the distance between two opposite guide wheels is 2 mm less than the width of the material to be formed.

[0015] Preferably, the die-changing mechanism includes a lifting vehicle. Cylinders III are symmetrically arranged on the upper surface of the lifting vehicle. The lower surface of the die is slidably connected to the upper surface of the lifting vehicle. Fixing grooves adapted to the hydraulic cylinders II are formed on the lower surface of the die. Pneumatic motors are fixedly connected to the inner walls of each of the fixing grooves respectively. The rotating part of the pneumatic motor is fixedly connected with a rotating block. Jacks adapted to the limiting posts on the upper surface of the limiting blocks are formed at both ends of the rotating block respectively. The surface of the limiting post is slidably inserted into the inner wall of the jack. The lower surface of the die is slidably connected to the surface of the slide bar.

[0016] Preferably, a lubricating coating is applied to the lower surface of the clamping block, and the lower surface of the clamping block is in contact with the upper surface of the material to be formed placed on the upper surface of the support plate.

[0017] Preferably, rubber pads are arranged on the side surfaces in the vertical direction of the support plate.

[0018] Preferably, for the forming method of a stamping and forming device for new energy vehicle parts, the operation steps are as follows:

[0019] Step 1: Before stamping, place a row of materials to be formed in the material box. The lower end of the descending material to be formed presses against the arc-shaped clamping block until the material to be formed completely descends into the material box. The clamping block returns to its original state under the action of the torsion spring. At this time, the lower surface of the clamping block just contacts the upper surface of the material to be formed.

[0020] Step 2: The cylinder II and the motor start working simultaneously. The cylinder II drives the push rod fixedly connected to the piston rod to move. The push rod generates a thrust on the side surface of the material to be formed. The material to be formed moves towards one end of the conveying chain. When one end of the material to be formed contacts the surface of the rotating guide wheel during the movement, the two guide wheels on both sides exert extrusion on both sides of the material to be formed. The rubber guide wheels deform under pressure. At this time, the friction force of the guide wheels on both sides of the material to be formed reaches the maximum. Under the combined action of the guide wheels and the push rod, the material to be formed moves between two adjacent limiting rods of the conveying chain. When one end of the material to be formed contacts the side surface of the support plate, the friction force between the material to be formed and the two guide wheels is 0 and the surface of the guide wheels no longer contacts any side surface of the material to be formed. Then start the conveying chain. The conveying chain drives the material to be formed to move between the punching die and the die. The conveying chain stops conveying. The ejector block starts to rise and the punching die starts to descend at the same time. When the two are completely fitted together, the material to be formed rises under the action of the ejector block. The lower surface of the material to be formed is above the limiting rod, and the feeding mechanism continues the feeding action.

[0021] Step 3, hydraulic cylinder 2 drives the limit block to start rising, and hydraulic cylinder 2 drives the limit block above it into the fixed groove on the lower surface of the mold until the lower surface of the limit block contacts the lower surface of the rotating block, hydraulic cylinder 2 stops rising, and the limit column at the upper end of the limit block is inserted into the jack of the rotating block. The pneumatic motor drives the rotating block to rotate 90 degrees, and hydraulic cylinder 2 continues to rise until it drives the mold to complete the stamping and forming action of the material to be formed. After the forming is completed, the ejector block and the mold descend at the same time. During the descent of the ejector block, the material to be stamped and formed is blocked by the conveyor chain and overlapped on the surface of the conveyor chain, and the conveyor chain moves out of the stamping and forming area;

[0022] Step 4. When replacing the mold, control the lifting car to move to the bottom of the protrusion of the forming base until the side of the lifting car contacts the body of the forming base, the lifting car stops moving, the pneumatic motor rotates 90 degrees in the opposite direction, and the threaded connection effect between the limit block and the upper end of the hydraulic cylinder 2 is released. The hydraulic cylinder 2 drops again, driving the limit block to leave the fixed groove. At this time, the limit block is completely located in the fixed hole. The cylinder starts to push the mold to the side of the lifting car until the mold is completely moved to the surface of the lifting car. The cylinder 1 returns to its original state, the lifting car removes the mold, and the mold to be replaced is driven by the lifting car to the bottom of the concave and convex part of the forming base. The cylinder 3 pushes the replaced mold to slide and connect with the slide bar until the mold is fully entered. Execute step 3 to complete the replacement of the mold and the subsequent stamping process.

[0023] The beneficial effects of the present invention are:

[0024] 1. By setting up a feeding mechanism, the material to be formed can be automatically fed, which reduces the time and manpower required for manual feeding, avoids the untimely feeding and feeding errors that may occur in manual operation, and allows the entire stamping process to continue uninterruptedly, thereby effectively increasing the number of parts produced per unit time and improving overall production efficiency.

[0025] 2. By setting up a conveying mechanism, it plays a role in conveying the material to be formed, and can accurately and quickly convey the material to the corresponding position of the forming component according to the set rhythm and route, ensuring that the material can enter the stamping forming link in time, and cooperate with other mechanisms tacitly to further help the entire production process to operate efficiently and avoid production delays caused by poor material transportation.

[0026] 3. By setting up a die-changing mechanism, it realizes the action of die replacement, which means that for new energy vehicle parts of different models and specifications, the corresponding dies can be quickly replaced for stamping production. On the one hand, it can meet the diverse production needs. On the other hand, after die replacement, it can ensure that each part is stamped and formed according to the accurately matched die specifications, which is conducive to improving the consistency and accuracy of products and ensuring the stability of product quality.

[0027] 4. According to the beneficial effects 1-3, the automation, precision, and high efficiency of the stamping and forming process of new energy vehicle parts are realized. These measures work together to significantly improve production efficiency, reduce labor costs, reduce the error rate in the production process, and ensure the stability and consistency of product quality.

Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] Referring to Figures 1-13 , a stamping and forming device for new energy vehicle parts, as Figure 1 shown, includes a forming component 1. A conveying mechanism 2 is arranged at the upper end of the forming component 1. A feeding mechanism 3 is arranged on one side of the forming component 1. A die-changing mechanism 4 is arranged on one side of the forming component 1. A punching die 5 is arranged above the forming component 1. A material to be formed 6 is placed at the upper end of the conveying mechanism 2.

[0044] The forming component 1 is to realize the action of providing support for the material to be formed 6.

[0045] In order to realize the action of conveying the material to be formed 6, a conveying mechanism 2 is set, which plays the role of conveying the material to be formed 6, and can accurately and quickly convey the material to the corresponding position of the forming component 1 according to the set rhythm and route, ensuring that the material can enter the stamping and forming link in time, and cooperate with other mechanisms tacitly to further help the entire production process to operate efficiently and avoid production delays caused by poor material transportation.

[0046] In order to realize the action of automatic feeding of the material to be formed 6, a feeding mechanism 3 is set, which can realize the action of automatic feeding of the material to be formed 6, reducing the time and manpower required for manual feeding, avoiding the untimely feeding and feeding errors that may occur in manual operation, so that the entire stamping process can continue uninterruptedly, thereby effectively increasing the number of parts produced per unit time and improving the overall production efficiency.

[0047] In order to realize the action of replacing the mold 43, a mold changing mechanism 4 is set. The mold changing mechanism 4 includes a mold 43, which realizes the action of replacing the mold 43. This means that for new energy vehicle parts of different models and specifications, the corresponding mold 43 can be quickly replaced for stamping production. On the one hand, it can meet diversified production needs. On the other hand, after the mold 43 is replaced, it can ensure that each part is stamped and formed according to the specifications of the precisely matched mold 43, which is conducive to improving the consistency and precision of the product and ensuring the stability of product quality.

[0048] In this embodiment, if Figures 4-7 and Figure 13 As shown, the forming component 1 includes a forming base 11, which is set to an "Ω" shape. A slot is opened inside the forming base 11, and an ejector block 12 is slidably connected to the inner wall of the slot. A lifting groove compatible with the mold 43 is opened at the center of the body of the ejector block 12, and a hydraulic cylinder 13 is arranged in an array on the lower surface of the ejector block 12. The lower end of the hydraulic cylinder 13 is embedded in the body of the forming base 11, and a cylinder 14 is embedded in one side of the forming base 11. Slide bars 15 are symmetrically arranged on the body surface of the forming base 11. The two slide bars 15 are respectively located on both sides of the piston rod of the cylinder 14. A triangular fixing hole 16 is opened between the two slide bars 15. The inner wall of the fixing hole 16 is fixedly connected to a hydraulic cylinder 2 17. The upper end of the hydraulic cylinder 2 17 is threadedly connected to a limit block 18, and the upper surface of the limit block 18 is symmetrically provided with limit columns.

[0049] Specifically, a lifting groove adapted to the mold 43 is provided at the central position of the body of the ejector block 12, which means that the mold 43 can be precisely matched with the ejector block 12. During the stamping process, the mold can perform corresponding up and down movements and other operations in the lifting groove to ensure the accuracy and standardization of part stamping. The setting of the slide bar 15 facilitates the limiting action when replacing the mold 43; the limiting block 18 is threadedly connected to the upper end of the second hydraulic cylinder 17, and the maximum rotation angle of the limiting block 18 is 90 degrees. Through the above settings, after the limiting block 18 rotates under force, it is further fixed to the upper end of the second hydraulic cylinder 17, and at the same time, the rotated limiting block 18 forms a clamping effect in the fixing groove.

[0050] In this embodiment, as Figure 3 and Figure 8 shown, the conveying mechanism 2 includes support columns 21 arrayed on the upper surface of the forming base 11. A gear 22 is rotatably provided at the upper end of each support column 21. A conveying chain 23 is engaged with the surface of the gear 22. Limiting rods 24 are arrayed on the upper surface of the conveying chain 23. The lower end of the limiting rod 24 is fixedly connected to the upper end of a single component of the conveying chain 23. A chain groove adapted to the conveying chain 23 is provided at the raised portion of the forming base 11. A support plate 27 is fixedly connected to one side of the feeding mechanism 3. An auxiliary plate 25 is fixedly connected to the upper surface of the support plate 27. Ball bearings 26 are arrayedly embedded in the plate body of the auxiliary plate 25. The surface of the ball bearings 26 is slidably connected to the lower surface of the material to be formed 6.

[0051] Specifically, the conveying mechanism 2 realizes the conveying of materials by arraying support columns 21 on the upper surface of the forming base 11 and rotatably providing gears 22 at the upper ends of the support columns 21 and using the meshing of the gears 22 with the conveying chain 23. This transmission method makes the operation of the conveying chain 23 relatively stable. Compared with some simple direct friction transmission methods, the meshing of the gears 22 with the conveying chain 23 can provide more precise power transmission, ensuring that the conveying chain 23 moves according to a fixed rhythm and route, reducing the possibility of unstable situations such as shaking and deviation during the conveying process, thereby ensuring that the material to be formed 6 can be stably conveyed to the corresponding position of the forming component; the limiting rods 24 can effectively limit the material to be formed 6. During the movement of the material along with the conveying chain 23, it prevents the material from slipping or shifting from the conveying chain 23 due to inertia, vibration, etc., ensuring that the material always remains in the correct conveying position, improving the accuracy of material conveying, and also laying a foundation for accurately entering the stamping and forming link subsequently; the auxiliary plate 25 fixedly connected to the upper surface of the support plate 27 provides a transition support area for the material to be formed 6. When the material is transferred from the feeding mechanism 3 to the conveying chain 23, the auxiliary plate 25 can assist in carrying the material, making the transfer process of the material smoother and avoiding problems such as material dropping and jamming due to the loose connection between feeding and conveying.

[0052] In this embodiment, as Figure 3 , Figures 8-10 shown, the feeding mechanism 3 includes a material box 31. The inner bottom wall of the material box 31 is provided with springs 32 in an array. The upper ends of the springs 32 are fixedly connected to a support plate 33. The material to be formed 6 is placed in the material box 31. Cylinders two 34 are fixedly connected to the two side surfaces of the material box 31 respectively. The piston rods of the cylinders two 34 are fixedly connected to a push rod 35. The surface of the push rod 35 is in contact with one side surface of the material to be formed 6. Rotation grooves are symmetrically formed at the upper end of the material box 31. A block 36 with one surface being arc-shaped is rotatably connected to the inner wall of each rotation groove. A torsion spring 37 is fixedly connected to one side of the block 36. One end of the torsion spring 37 is fixedly connected to the inner wall of the rotation groove. Motors 38 are respectively arranged at the two opposite corners at the upper end of the material box 31. The surfaces of the motors 38 are fixedly connected to the body of the material box 31. The output shafts of the motors 38 are fixedly connected to spur gears one 39. Spur gears two 310 are respectively meshed with the two sides of the spur gear one 39. A bearing 311 is arranged above the spur gear two 310. The outer ring of the bearing 311 is fixedly connected to the body of the material box 31. A guide wheel 312 is arranged above the bearing 311. The lower end of the guide wheel 312 is fixedly connected to the inner ring of the bearing 311 through a connecting rod. The lower end of the connecting rod is fixedly connected to the upper end of the spur gear two 310.

[0053] Specifically, the block 36 is in a certain blocking posture under the torsion of the torsion spring 37. When placing materials into the material box 31, the materials can smoothly enter the box along the arc surface of the block 36; when the materials tend to escape upward from the material box 31, the block 36 will play a blocking role with the assistance of the torsion spring 37, effectively preventing the materials from accidentally falling, ensuring the storage stability of the materials in the material box 31, and at the same time limiting the stacking height of the materials to a certain extent, avoiding excessive stacking of the materials beyond the expected range and affecting the normal development of the feeding operation; the guide wheel 312 plays an important guiding and auxiliary conveying role during the feeding process of the materials. After the materials are pushed by the push rod 35 to the position where the guide wheel 312 is located, they will move forward more smoothly and accurately in the rolling guidance of the guide wheel 312 towards the predetermined feeding direction.

[0054] In this embodiment, the guide wheel 312 is made of rubber material, and the distance between the two opposite guide wheels 312 is 2 millimeters smaller than the width of the material to be formed 6.

[0055] Specifically, when guiding and assisting in the conveyance of the to-be-formed material 6, it can generate an appropriate amount of frictional force with the surface of the material. On the one hand, this frictional force is sufficient to drive the material to move in a predetermined direction by the guide wheel 312, ensuring that the material does not slip or stagnate during the process of transitioning from the material box 31 to the conveying mechanism, etc., and guaranteeing the smoothness of feeding. On the other hand, compared with some materials with excessive frictional force, rubber will not cause scratches or other damages to the surface of the material due to excessive friction, which is beneficial to maintaining the integrity of the appearance of the material, and thus ensuring the quality of the subsequent stamping-formed parts.

[0056] In this embodiment, as Figure 3 and Figure 12 shown, the die-changing mechanism 4 includes a lift truck 41. Cylinders three 42 are symmetrically arranged on the upper surface of the lift truck 41. The lower surface of the die 43 is slidably connected to the upper surface of the lift truck 41. A fixing groove adapted to the hydraulic cylinder two 17 is provided on the lower surface of the die 43. The inner walls of each fixing groove are respectively fixedly connected with a pneumatic motor 44. The rotating part of the pneumatic motor 44 is fixedly connected with a rotating block 45. Insertion holes adapted to the limiting columns on the upper surface of the limiting block 18 are respectively provided at both ends of the rotating block 45. The surface of the limiting column is slidably inserted into the inner wall of the insertion hole. The lower surface of the die 43 is slidably connected to the surface of the slide bar 15.

[0057] Specifically, the hydraulic cylinder two 17 drives the limiting block 18 to start rising. The hydraulic cylinder two 17 drives the limiting block 18 above it into the fixing groove on the lower surface of the die 43 until the lower surface of the limiting block 18 contacts the lower surface of the rotating block 45. The hydraulic cylinder two 17 stops rising. The limiting column at the upper end of the limiting block 18 is inserted into the insertion hole of the rotating block 45. The pneumatic motor 44 drives the rotating block 45 to rotate 90 degrees. Then the hydraulic cylinder two 17 continues to rise. Thus, the action of fixing the die 43 is completed.

[0058] In this embodiment, a lubricating coating is applied to the lower surface of the clamping block 36. The lower surface of the clamping block 36 is in contact with the upper surface of the to-be-formed material 6 placed on the upper surface of the support plate 33.

[0059] Specifically, the existence of the lubricating coating is like a protective film, reducing the possible wear on the surface of the material when the clamping block 36 directly contacts and frictions with the material, helping to maintain the integrity of the appearance of the material, and ensuring that the parts of new energy vehicles stamped subsequently will not have quality defects due to the pre-damage of the material surface.

[0060] In this embodiment, a rubber pad is provided on the side surface of the pallet 27 in the vertical direction.

[0061] Specifically, during the operation of the stamping and forming equipment for new energy vehicle parts, the pallet 27 plays an auxiliary supporting and transitional role. When the material is transferred from the feeding mechanism 3 to the conveying mechanism 2, it may collide with the vertical side surface of the pallet 27. The setting of the rubber pad can effectively buffer this collision force, avoiding situations such as deformation and damage of the material due to rigid collision, ensuring that the material can enter the conveying link intact, and improving the quality and success rate of material conveying.

[0062] Refer to Figures 1-13 , a forming method for stamping and forming equipment of new energy vehicle parts, and the operation steps are as follows:

[0063] Step 1: Before stamping, place a column of materials 6 to be formed in the material box 31. The lower end of the descending material 6 to be formed presses against the arc-shaped block 36 until the material 6 to be formed completely descends into the material box 31. The block 36 returns to its original state under the action of the torsion spring 37. At this time, the lower surface of the block 36 just contacts the upper surface of the material 6 to be formed.

[0064] Step 2: The cylinder two 34 and the motor 38 start working simultaneously. The cylinder two 34 drives the push rod 35 fixedly connected to the piston rod to move. The push rod 35 generates a thrust on the side surface of the material 6 to be formed. The material 6 to be formed moves towards one end of the conveying chain 23. When one end of the material 6 to be formed contacts the surface of the rotating guide wheel 312 during the movement, the two guide wheels 312 on both sides generate extrusion on both sides of the material 6 to be formed. The rubber guide wheels 312 deform under pressure. At this time, the frictional force of the guide wheels 312 on both sides of the material 6 to be formed reaches the maximum. Under the combined action of the guide wheels 312 and the push rod 35, the material 6 to be formed moves between two adjacent limiting rods 24 of the conveying chain 23. When one end of the material 6 to be formed contacts the side surface of the pallet 27, the frictional force between the material 6 to be formed and the two guide wheels 312 is 0 and the surface of the guide wheels 312 no longer contacts any side surface of the material 6 to be formed. Then start the conveying chain 23. The conveying chain 23 drives the material 6 to be formed to move between the punching die 5 and the die 43. The conveying chain 23 stops conveying. The ejector block 12 starts to rise and the punching die 5 starts to descend simultaneously. When the two are completely fitted together, the material 6 to be formed rises under the action of the ejector block 12. The lower surface of the material 6 to be formed is above the limiting rod 24, and the feeding mechanism 3 continues the feeding action.

[0065] Step 3: The second hydraulic cylinder 17 drives the limit block 18 to start rising. The second hydraulic cylinder 17 drives the limit block 18 above it into the fixed groove on the lower surface of the mold 43 until the lower surface of the limit block 18 contacts the lower surface of the rotating block 45. The second hydraulic cylinder 17 stops rising. The limit post at the upper end of the limit block 18 is inserted into the jack of the rotating block 45. The pneumatic motor 44 drives the rotating block 45 to rotate 90 degrees. Then the second hydraulic cylinder 17 continues to rise until it drives the mold 43 to complete the stamping and forming action on the material to be formed 6. After the forming is completed, the ejector block 12 and the mold 43 descend simultaneously. During the descent of the ejector block 12, the material to be formed 6 that has been stamped and formed is blocked by the conveyor chain 23, overlaps on the surface of the conveyor chain 23, and is moved out of the stamping and forming area by the conveyor chain 23;

[0066] Step 4: When replacing the mold 43, control the lift truck 41 to move below the protrusion of the forming base 11 until the side of the lift truck 41 contacts the body of the forming base 11. The lift truck stops moving. The pneumatic motor 44 rotates 90 degrees in the reverse direction to release the threaded connection effect between the limit block 18 and the upper end of the second hydraulic cylinder 17. The second hydraulic cylinder 17 descends again, driving the limit block 18 out of the fixed groove. At this time, the limit block 18 is completely located in the fixing hole 16. The first cylinder 14 starts to push the mold 43 to move towards the side of the lift truck 41 until the mold 43 completely moves onto the surface of the lift truck 41. The first cylinder 14 returns to its original state. The lift truck 41 removes the mold 43, drives the mold 43 to be replaced to below the concave-convex part of the forming base 11 through the lift truck 41. The third cylinder 42 pushes the replaced mold 43 to be slidably connected with the slide bar 15 until the mold 43 completely enters. Executing Step 3 can complete the replacement of the mold 43 and the subsequent stamping process.

The second cylinder (34) drives the push rod (35) fixedly connected to the piston rod to move. The push rod (35) generates thrust on the side of the material to be formed (6). The material to be formed (6) moves toward one end of the conveyor chain (23). During the movement, one end of the material to be formed (6) contacts the surface of the rotating guide wheel (312). The guide wheels (312) on both sides squeeze the two sides of the material to be formed (6). The guide wheels (312) made of rubber material are deformed by the pressure.

The limit column at the upper end of the limit block (18) is inserted into the insertion hole of the rotating block (45), and the pneumatic motor (44) drives the rotating block (45) to rotate 90 degrees. The hydraulic cylinder 2 (17) then continues to rise until it drives the mold (43) to complete the stamping and forming action of the material to be formed (6).

During the descending process of the ejector block (12), the material to be formed (6) to be stamped is blocked by the conveyor chain (23) and overlaps the surface of the conveyor chain (23), and the conveyor chain (23) moves out of the stamping and forming area; Step 4: When replacing the mold (43), the lifting vehicle (41) is controlled to move to the lower part of the protrusion of the forming base (11) until the side of the lifting vehicle (41) contacts the body of the forming base (11). The lifting vehicle stops moving, and the pneumatic motor (44) rotates 90 degrees in the opposite direction to release the threaded connection between the limit block (18) and the upper end of the hydraulic cylinder (17). The hydraulic cylinder (17) descends again, driving the limit block (18) to leave the fixing groove. At this time, the limit block (18) is completely located in the fixing hole (16), and the cylinder (14) opens. The mold (43) is pushed toward the side of the lifting vehicle (41) until the mold (43) is completely moved to the surface of the lifting vehicle (41), and the cylinder (14) returns to its original state. The lifting vehicle (41) removes the mold (43), and the mold (43) to be replaced is driven by the lifting vehicle (41) to the bottom of the concave and convex part of the forming base (11). The cylinder (42) pushes the replaced mold (43) to slide and connect with the slide bar (15) until the mold (43) is completely inserted. The replacement of the mold (43) and the subsequent stamping process can be completed by executing step three.
