[0014] Preferably, the forming method of the new energy vehicle parts stamping forming equipment comprises the following operating steps: Step 1: Before stamping, place a row of materials to be formed in a material box, and the lower end of the descending materials to be formed squeezes the arc-shaped block until the materials to be formed are completely descended into the material box, and the block returns to its original shape under the action of the torsion spring, and the lower surface of the block just contacts the upper surface of the materials to be formed; Step 2, cylinder 2 and the motor start working at the same time, cylinder 2 drives the push rod fixedly connected to the piston rod to move, the push rod generates thrust on the side of the material to be formed, and the material to be formed moves toward one end of the conveyor chain. During the movement, one end of the material to be formed contacts the surface of the rotating guide wheel, and the guide wheels on both sides squeeze the two sides of the material to be formed. The guide wheels made of rubber material are deformed by 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 joint action of the guide wheels and the push rod, the material to be formed moves between two adjacent limit rods of the conveyor chain. When one end of the material to be formed contacts the side 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 wheel no longer contacts any side of the material to be formed. Then the conveyor chain is started, and the conveyor chain drives the material to be formed to move between the die and the mold. The conveyor chain stops conveying, the ejector block starts to rise and the die starts to fall. When the two are completely fitted to each other, the material to be formed rises under the action of the ejector block, and the lower surface of the material to be formed is located above the limit rod, and the feeding mechanism continues the feeding action; 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; 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.

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.

[0016] 2.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 13 , a new energy vehicle parts stamping forming equipment, such as Figure 1 As shown, it includes a forming part 1, a conveying mechanism 2 is arranged at the upper end of the forming part 1, a loading mechanism 3 is arranged at one side of the forming part 1, a mold changing mechanism 4 is arranged at one side of the forming part 1, a punching die 5 is arranged above the forming part 1, and a material 6 to be formed is placed at the upper end of the conveying mechanism 2.

[0023] The forming component 1 is used to provide support for the material 6 to be formed.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] In this embodiment, if Figure 4-Figure 7 and Fig.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.

[0028] Specifically, a lifting groove compatible with the mold 43 is opened at the center position of the ejector block 12 body, which means that the mold 43 can accurately cooperate with the ejector block 12. During the stamping process, the mold can perform corresponding up and down movements in the lifting groove to ensure the accuracy and standardization of part stamping. The setting of the slide bar 15 facilitates a limiting action when replacing the mold 43; the limit block 18 is threadedly connected to the upper end of the hydraulic cylinder 17, and the maximum rotation angle of the limit block 18 is 90 degrees. Through the above setting, the limit block 18 is further fixed to the upper end of the hydraulic cylinder 17 after being rotated under force, and the rotated limit block 18 forms a clamping effect in the fixed groove.

[0029] In this embodiment, if Figure 3 and Figure 8As shown, the conveying mechanism 2 includes support columns 21 arranged in an array on the upper surface of the forming base 11, and a gear 22 is rotatably arranged on the upper end of each support column 21. A conveying chain 23 is meshed on the surface of the gear 22. A limit rod 24 is arranged in an array on the upper surface of the conveying chain 23. The lower end of the limit rod 24 is fixedly connected to the upper end of a single component of the conveying chain 23. A chain groove matching the conveying chain 23 is provided at the protrusion of the forming base 11. A support plate 27 is fixedly connected to one side of the feeding mechanism 3, and an auxiliary plate 25 is fixedly connected to the upper surface of the support plate 27. Balls 26 are embedded in the plate array of the auxiliary plate 25, and the surface of the ball 26 is slidably connected to the lower surface of the material 6 to be formed.

[0030] Specifically, the conveying mechanism 2 realizes the conveying of materials by arranging support columns 21 in an array on the upper surface of the forming base 11, and rotatably arranging gears 22 at the upper ends of the support columns 21 to mesh with the conveying chain 23. This transmission method makes the conveying chain 23 run more smoothly. Compared with some simple direct friction transmission methods, the meshing of the gear 22 and the conveying chain 23 can provide more accurate power transmission, ensuring that the conveying chain 23 moves according to a fixed rhythm and route, reducing the possibility of unstable conditions such as shaking and deviation during the conveying process, thereby ensuring that the material 6 to be formed can be stably conveyed to the corresponding position of the forming component; the limit rod 24 can The material 6 plays an effective limiting role. When the material moves along the conveyor chain 23, it prevents the material from sliding off the conveyor chain 23 or shifting its position due to inertia, vibration, etc., ensuring that the material is always in the correct conveying position, improving the accuracy of material conveying, and laying the foundation for the subsequent accurate entry into the stamping and forming link; the auxiliary plate 25 fixedly connected to the upper surface of the support plate 27 provides a transition support area for the material 6 to be formed. When the material is transferred from the feeding mechanism 3 to the conveyor chain 23, the auxiliary plate 25 can assist in carrying the material, making the material transfer process smoother and smoother, avoiding problems such as material falling and jamming due to loose connection between feeding and conveying.

[0031] In this embodiment, if Figure 3 , Figure 8-Figure 10As shown, the feeding mechanism 3 includes a material box 31, the inner bottom wall array of the material box 31 is provided with a spring 32, the upper end of the spring 32 is fixedly connected to a support plate 33, the material 6 to be formed is placed in the material box 31, the two side surfaces of the material box 31 are respectively fixedly connected to the cylinder 2 34, the piston rod of the cylinder 2 34 is fixedly connected to a push rod 35, the surface of the push rod 35 is in contact with one side of the material 6 to be formed, the upper end of the material box 31 is symmetrically provided with rotating grooves, the inner wall of each rotating groove is respectively rotatably connected to a clamping block 36 with one side set to be in an arc shape, one side of the clamping block 36 is fixedly connected to a torsion spring 37, one end of the torsion spring 37 is connected to The inner wall of the rotating groove is fixedly connected, and motors 38 are respectively arranged at two opposite corners of the upper end of the material box 31. The surface of the motor 38 is fixedly connected to the body of the material box 31, and the output shaft of the motor 38 is fixedly connected to a spur gear 1 39. The two sides of the spur gear 1 39 are respectively meshed with spur gear 2 310. A bearing 311 is arranged above the spur gear 2 310. 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, and the lower end of the connecting rod is fixedly connected to the upper end of the spur gear 2 310.

[0032] Specifically, the block 36 is in a certain blocking posture under the torsion force of the torsion spring 37. When placing materials in the material box 31, the materials can smoothly enter the box along the curved surface of the block 36; and when the materials tend to escape from the material box 31 upward, the block 36 will play a blocking role with the help 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, it also limits the stacking height of the materials to a certain extent, avoiding excessive accumulation of materials beyond the expected range and affecting the normal feeding operation; the guide wheel 312 plays an important guiding and auxiliary conveying role in the material feeding process. After the materials are pushed to the position of the guide wheel 312 by the push rod 35, they will move more smoothly and accurately in the predetermined feeding direction under the rolling guidance of the guide wheel 312.

[0033] In this embodiment, the guide wheels 312 are made of rubber, and the distance between two opposite guide wheels 312 is 2 mm smaller than the width of the material 6 to be formed.

[0034] Specifically, when guiding and assisting the conveying of the material 6 to be formed, it can generate moderate friction with the surface of the material. On the one hand, this friction is sufficient to enable the guide wheel 312 to drive the material to move in a predetermined direction, ensuring that the material will not slip or stagnate during the transition from the material box 31 to the conveying mechanism, thereby ensuring smooth feeding. On the other hand, compared with some materials with excessive friction, rubber will not cause scratches or other damage to the surface of the material due to excessive friction, which is beneficial to maintaining the integrity of the material appearance, thereby ensuring the quality of subsequent stamping parts.

[0035] In this embodiment, if Figure 3 and Fig.12 As shown, the mold changing mechanism 4 includes a lifting vehicle 41, and the upper surface of the lifting vehicle 41 is symmetrically provided with cylinder three 42, the lower surface of the mold 43 is slidably connected to the upper surface of the lifting vehicle 41, and the lower surface of the mold 43 is provided with a fixed groove adapted to the hydraulic cylinder two 17, and the inner wall of each fixed groove is fixedly connected with an air motor 44, and the rotating part of the air motor 44 is fixedly connected with a rotating block 45, and the two ends of the rotating block 45 are respectively provided with sockets adapted to the limit column on the upper surface of the limit block 18, the surface of the limit column is slidably plugged with the inner wall of the socket, and the lower surface of the mold 43 is slidably connected to the surface of the slide bar 15.

[0036] Specifically, hydraulic cylinder 17 drives the limit block 18 to start rising, and hydraulic cylinder 17 drives the limit block 18 above it to enter 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. Hydraulic cylinder 17 stops rising, and the limit column at the upper end of the limit block 18 is inserted into the socket of the rotating block 45. The pneumatic motor 44 drives the rotating block 45 to rotate 90 degrees. Hydraulic cylinder 17 then continues to rise, thereby completing the action of fixing the mold 43.

[0037] In this embodiment, the lower surface of the clamping block 36 is coated with a lubricating coating, and 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 .

[0038] Specifically, the presence of the lubricating coating acts like a protective film, which reduces the wear on the material surface that may be caused by direct contact and friction between the block 36 and the material, helps maintain the integrity of the material appearance, and ensures that the subsequent stamped new energy vehicle parts will not have quality defects due to previous damage to the material surface.

[0039] In this embodiment, rubber pads are provided on the side surfaces of the support plate 27 in the vertical direction.

[0040] Specifically, during the operation of the entire new energy vehicle parts stamping and forming equipment, the support plate 27 plays an auxiliary support and transition role. When the material is transferred from the feeding mechanism 3 to the conveying mechanism 2, it may collide with the vertical side of the support plate 27. The setting of the rubber pad can effectively buffer this collision force, avoid deformation and damage of the material due to rigid collision, ensure that the material can enter the conveying link intact, and improve the quality and success rate of material transportation.

[0041] Reference Figure 1-Figure 13 , a forming method of a new energy vehicle parts stamping forming equipment, the operating steps are as follows: Step 1: Before stamping, a row of materials 6 to be formed is placed in the material box 31, and the lower end of the descending materials 6 to be formed presses the arc-shaped block 36 until the materials 6 to be formed are completely descended into the material box 31, and the block 36 is restored to its original state under the action of the torsion spring 37, and the lower surface of the block 36 is just in contact with the upper surface of the materials 6 to be formed; Step 2, cylinder 2 34 and motor 38 start working at the same time, cylinder 2 34 drives push rod 35 fixedly connected to piston rod to move, push rod 35 generates thrust on the side of material 6 to be formed, material 6 to be formed moves toward one end of conveyor chain 23, during the movement, one end of material 6 to be formed contacts with the surface of rotating guide wheel 312, guide wheels 312 on both sides squeeze both sides of material 6 to be formed, guide wheels 312 made of rubber material are deformed by pressure, at this time, friction force of guide wheels 312 on both sides of material 6 to be formed reaches maximum, under the joint action of guide wheels 312 and push rod 35, material 6 to be formed moves to conveyor chain 23 When one end of the material 6 to be formed contacts the side of the support plate 27, the friction between the material 6 to be formed and the two guide wheels 312 is 0 and the surface of the guide wheel 312 no longer contacts any side of the material 6 to be formed. Then, the conveyor chain 23 is started, and the conveyor chain 23 drives the material 6 to be formed to move between the die 5 and the mold 43. The conveyor chain 23 stops conveying, and the ejector block 12 starts to rise while the die 5 starts to fall. When the two are completely fitted to each other, the material 6 to be formed rises under the action of the ejector block 12, and the lower surface of the material 6 to be formed is located above the limit rod 24, and the feeding mechanism 3 continues the feeding action. Step 3, the hydraulic cylinder 17 drives the limit block 18 to start rising, and the hydraulic cylinder 17 drives the limit block 18 above it to enter 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, and the hydraulic cylinder 17 stops rising. The limit column at the upper end of the limit block 18 is inserted into the jack of the rotating block 45, and the pneumatic motor 44 drives the rotating block 45 to rotate 90 degrees. The hydraulic cylinder 17 continues to rise until it drives the mold 43 to complete the stamping and forming action of the material 6 to be formed. After the forming is completed, the ejector block 12 and the mold 43 descend at the same time. During the descent of the ejector block 12, the material 6 to be formed by the stamping is blocked by the conveyor chain 23 and overlapped on the surface of the conveyor chain 23, and the conveyor chain 23 moves out of the stamping and forming area; The fourth step is to replace the mold 43 by controlling the lifting vehicle 41 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, the pneumatic motor 44 rotates 90 degrees in the opposite direction, and the threaded connection effect between the limit block 18 and the upper end of the hydraulic cylinder 2 17 is released. The hydraulic cylinder 2 17 descends again, driving the limit block 18 to leave the fixed groove. At this time, the limit block 18 is completely located in the fixing hole 16, and the cylinder 1 14 starts to push the mold 43 to move to 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 1 14 returns to its original state.

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. At this time, the friction force of the guide wheels (312) on the two sides of the material to be formed (6) reaches the maximum.

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). After the forming is completed, the ejector block (12) and the mold (43) descend at the same time. 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.
