Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to a stamping equipment and a stamping method for automobile parts. Background Art

[0002] Stamping equipment is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet materials to deformation force in the die, thereby obtaining product parts with certain shapes, sizes and performances. There are a large number of parts in automobile parts that need stamping processing. Among them, small parts such as seat accessories, interior panels, fixings, instrument panel parts, suspension systems, etc. usually need to cut the sheet materials into specific shapes first, and then use stamping equipment to stamp them into fixed shapes or punch holes.

[0003] Small parts stamping equipment usually uses 250T punch press or 350T punch press. When changing the mold of 205T punch press or 350T punch press, the mold is usually placed on the mold cart manually, and then the mold is pushed to the side of the punch press by the mold cart, and the connection between the lower mold and the punch press platform, the upper mold and the slider are removed, and then the mold on the mold cart is pushed onto the punch press. In the prior art, in order to make it easier for workers to change molds, a lifting pulley is added to the platform. When the upper or lower mold is needed, the pulley rises to the same height as the mold cart, and the friction between the mold and the punch press platform is reduced by the pulley, thereby saving effort. However, in actual use, for the 305T punch press, due to the large mold, there is still a problem of laboriousness, and the common problem of the 250T punch press and the 350T punch press is that the parking position of the mold is not easy to control, and it is easy to have repeated adjustments.

[0060] Referring to Figures 1 - 2 , the present invention provides a stamping device for automotive parts, including a bracket 110. The bracket 110 has a platform 111, and the platform 111 is used to support the lower die. The lower pressing plate 112 is arranged on the bracket 110 in a lifting manner, and the lower pressing plate 112 is used to support the upper die. It further includes an extension frame 200. The extension frame 200 is rotatably arranged on the bracket 110, and after rotation, it is parallel to the platform 111; a sliding seat 210 is slidably arranged on the extension frame 200, and after the sliding seat 210 slides, it approaches or moves away from the platform 111; a top plate 220 is slidably arranged on the sliding seat 210, and the sliding direction of the top plate 220 is parallel to the sliding direction of the sliding seat 210. The sliding seat 210 is used to push the die close to the platform 111, and the top plate 220 is used to push the die into the installation position.

[0061] In this embodiment, the extension frame 200 is rotatably arranged on the bracket 110 and can be parallel to the platform 111 after rotation. The extension of the extension frame 200 avoids the lower pressing plate 112, enabling the die to be placed on the extension frame 200 by hoisting. Moreover, the rotatable extension frame 200 can be stored on the side of the bracket 110, saving more space when not in use. After the extension frame 200 rotates to be parallel to the platform 111, it can be supported on the extension frame 200 by an inclined support hinged below the rotation axis of the extension frame 200, and the contact point between the extension frame 200 and the inclined support is plugged together by a pin. The inclined support, the bracket 110, and the extension frame 200 form a stable triangular shape, which not only has good stability but also has less modification to the original stamping device and low modification cost. The sliding seat 210 can slide on the extension frame 200 in the way of a slide rail or a chute 113 and can approach or move away from the platform 111 when sliding. The top plate 220 can slide on the sliding seat 210, and its sliding direction is parallel to the sliding direction of the sliding seat 210.

[0062] In actual operation, the sliding seat 210 is used to push the mold close to the platform 111, and the top plate 220 is used to further push the mold into the accurate installation position. When a new mold needs to be placed on the platform 111 again, first rotate the extension frame 200 to a position parallel to the platform 111, then place the mold on the extension frame 200 by means of a crane. Drive the sliding seat 210 to slide by using the driving device, so that the sliding seat 210 drives the top plate 220 to abut against the mold on the extension frame 200 and push the mold to slide on the extension frame 200 in the direction close to the platform 111. After the sliding seat 210 slides to the limit position of the slide rail or chute 113, the sliding seat 210 stops sliding. The operator can make the top plate 220 slide relative to the sliding seat 210 by means of a servo motor or by rotating the lead screw, and the top plate 220 continues to push the mold to move to the installation position of the mold. The movement of the mold can be realized by the sliding of the sliding seat 210, so that the mold is close to the platform 111, and then the mold is moved to the installation position by the movement of the top plate 220 relative to the sliding seat 210. The top plate 220 is equivalent to a precise positioning device, which avoids the mold moving beyond the installation position due to the operator exerting too much force.

[0063] This design method makes the lifting and placing of the mold more convenient and improves the operation efficiency of mold changing. The step-by-step movement of the sliding seat 210 and the top plate 220 can accurately control the position of the mold, ensure that the mold is accurately installed in place, and solve the problem of difficult positioning during mold changing. It avoids repeated adjustments caused by inaccurate installation positions of the mold, saving time and labor costs.

[0064] Refer to Figures 1 - 2 Further, the sliding seat 210 has a first threaded hole 211 and a plurality of support holes 212, and further includes a first screw 300. One end of the first screw 300 is rotatably arranged on the top plate 220, the other end passes through the first threaded hole 211, and the first screw 300 is threadedly connected to the first threaded hole 211; there are a plurality of support columns 400, one end is arranged on the top plate 220, the other end passes through the support holes 212, and the support columns 400 are slidably arranged relative to the support holes 212, and the axis of the support column 400 is parallel to the axis of the first screw 300.

[0065] In this embodiment, when a new mold needs to be placed, after the sliding seat 210 moves to the limit position, the operator rotates the first screw 300. Due to the threaded connection relationship between the first screw 300 and the sliding seat 210, and the support and guiding effect of the support column 400 on the top plate 220, the top plate 220 can achieve stable linear sliding on the sliding seat 210, so as to more accurately push the mold into the installation position. A rotating handle is arranged at the end of the first screw 300 away from the top plate 220, which is convenient for the operator to operate. Through the threaded connection relationship between the first screw 300 and the sliding seat 210, it further plays a role in saving effort.

[0066] In actual operation, the operator holds the rotating handle and easily rotates the first screw rod 300, driving the top plate 220 to steadily push the mold, ensuring that the mold reaches the installation position accurately without error, avoiding the deviation of the mold position caused by inaccurate manual pushing, and improving the precision and efficiency of mold installation. The threaded connection between the first screw rod 300 and the sliding seat 210, combined with the guidance of the support column 400, realizes the precise control of the movement of the top plate 220, improves the precision and stability of mold installation, and can also be applicable to molds of different sizes.

[0067] Refer to Figures 1 - 2 , further, the sliding seat 210 includes a sliding frame 213 which is slidably arranged on the extension frame 200, and the sliding frame 213 slides closer to or away from the platform 111 after sliding; a lifting member 214 is arranged on the sliding frame 213 in a lifting manner, and the top plate 220 is slidably arranged on the lifting member 214. The highest point of the top plate 220 is not higher than that of the lifting member 214. After the lifting member 214 rises, the highest point of the top plate 220 is higher than the extension frame 200. After the lifting member 214 descends, the highest point of the lifting member 214 is lower than the extension frame 200.

[0068] In this embodiment, the sliding seat 210 is composed of a sliding frame 213 and a lifting member 214. The sliding frame 213 is driven by a driving device and slides on the extension frame 200 in the form of a slide rail or a chute 113. The lifting member 214 is lifted and lowered on the sliding frame 213 by means of a lead screw. By lowering the lifting member 214, the height of the top plate 220 and the lifting member 214 is lower than the top surface of the extension frame 200. In this way, it is avoided that the mold presses on the top plate 220 when placing the mold on the extension frame 200. Moreover, by reducing the height of the top plate 220 and the lifting member 214, the mold cart can also be abutted against the extension frame 200, and the mold can be pushed onto the extension frame 200 by pushing.

[0069] After the mold is placed on the extension frame 200, the operator rotates the lead screw to drive the lifting member 214 to drive the top plate 220 to rise, so that the top plate 220 can contact the side surface of the mold, thereby pushing the mold. The cooperation between the sliding frame 213 and the lifting member 214 increases the flexibility and diversity of mold position adjustment, and can better meet the installation requirements of molds of different sizes and shapes. In actual operation, this cooperation method makes the placement and position adjustment of the mold more convenient and efficient. The operator can flexibly adjust the positions of the sliding frame 213 and the lifting member 214 according to the specific situation of the mold to ensure that the mold can be accurately installed at the designated position. By controlling the lifting and lowering of the lifting member 214 through the lead screw, the operation is simple and precise, reducing the operation difficulty and improving the work efficiency. The method of avoiding the mold pressing on the top plate 220 and facilitating the pushing and placing of the mold cart increases the convenience and safety of the operation.

[0070] Refer to Figures 1 - 3, Further, it further includes a first universal ball bearing table 500. The first universal ball bearing table 500 is arranged on the extension frame 200. After the extension frame 200 is parallel to the platform 111, the top surface of the first universal ball bearing table 500 is not lower than the platform 111. The first universal ball bearing table 500 is used to abut against the bottom of the mold.

[0071] In this embodiment, during actual operation, when the mold is placed on the extension frame 200, the first universal ball bearing table 500 can support the mold and reduce the frictional force, making the movement of the mold on the extension frame 200 smoother. Moreover, the first-direction ball bearing table can not only move the mold closer to the platform 111, but also facilitate the adjustment of the lateral position of the mold, reducing the difficulty of hoisting and placing the mold. For the lateral positioning of the mold during movement, it can rely on the positioning plate controlled by the lead screw on the platform 111. After the mold abuts against the positioning plate, the lateral positioning of the mold can be completed. The movement mode of the positioning plate relying on the lead screw not only has precise position adjustment and is easy to control, but also is applicable to molds of different sizes.

[0072] The setting of the first universal ball bearing table 500 reduces the frictional resistance between the mold and the extension frame 200, making the movement of the mold easier and more flexible. It helps to improve the position adjustment efficiency of the mold on the extension frame 200, reducing the operation time and labor intensity. It can better protect the bottom of the mold and avoid wear or damage during movement.

[0073] Refer to Figures 3 - 4 , Further, the platform 111 has a chute 113, and it further includes a first lifting frame 600. The first lifting frame 600 is arranged to be lifted and lowered in the chute 113. After the first lifting frame 600 is lifted or lowered, it extends out of or enters the chute 113; a second universal ball bearing table 700 is arranged on the first lifting frame 600. After the first lifting frame 600 rises, the height of the second universal ball bearing table 700 is the same as the height of the first universal ball bearing table 500. Both the first universal ball bearing table 500 and the second universal ball bearing table 700 are used for the movement of the mold.

[0074] In this embodiment, when the mold needs to be moved from the extension frame 200 to the platform 111, the first lifting frame 600 is raised so that the second universal ball bearing table 700 and the first universal ball bearing table 500 are at the same height, thereby providing continuous and stable support for the movement of the mold, reducing resistance, and facilitating the position adjustment and installation of the mold. After the mold is in the installation position, the first lifting frame 600 descends and enters the chute 113, enabling the mold to land smoothly on the platform 111.

[0075] The first lifting frame 600 and the second universal ball rolling table 700 further optimize the moving performance of the mold on the platform 111, improving the convenience and smoothness of operation. It ensures a smooth transition during the movement of the mold from the extension frame 200 to the platform 111, reducing jamming and position deviation caused by height differences or discontinuous supports. It can adapt to molds of different sizes and shapes, enhancing the versatility and applicability of the equipment.

[0076] Refer to Figures 3 - 4 , further, there are several first lifting frames 600, and several first lifting frames 600 are all used to support the second universal ball rolling table 700. The first lifting frame 600 is a lead screw lifting frame. It also includes a second screw rod 810, and the second screw rod 810 is rotatably arranged on the bracket 110. The second screw rod 810 is used to drive several first lifting frames 600 to lift.

[0077] In this embodiment, there are several first lifting frames 600, and these first lifting frames 600 are all used to support the second universal ball rolling table 700. The multiple first lifting frames 600 support together, improving the stability and reliability of the support for the second universal ball rolling table 700. It overcomes the defect that the size of the chute 113 on the platform 111 should not be too large and the structural parts of the first lifting frame 600 should not be too large in size. The width of the chute 111 does not exceed 15 cm. The first lifting frame 600 is a lead screw lifting frame. By rotating the second screw rod 810, several first lifting frames 600 can be driven to lift synchronously, so as to realize the lifting action of the second universal ball rolling table 700. The driving method of using the lead screw lifting frame and the second screw rod 810 makes the lifting action accurate and stable, and can realize the synchronous action of multiple lifting frames, ensuring the consistency of the lifting of the second universal ball rolling table 700.

[0078] Refer to Figures 3 - 4 , further, the first lifting frame 600 includes a base 610, and the base 610 is arranged at the bottom of the chute 113; a sliding member 620 is slidably arranged on the base 610, and the sliding member 620 has a second threaded hole 621. The second screw rod 810 is used to drive the sliding member 620 to slide; the scissor fork 630 has a first support rod 631 and a second support rod 632 that are hinged to each other. One end of the first support rod 631 is hinged to the base 610, and one end of the second support rod 632 is hinged to the sliding member 620; the other end of the first support rod 631 of the support table 640 is hinged to the support table 640, and the other end of the second support rod 632 is hinged and slidably arranged on the support table 640. After the sliding member 620 slides, the support table 640 rises or falls, and the second universal ball rolling table 700 is arranged on the support table 640.

[0079] In this embodiment, when the first lifting frame 600 is working, the base 610 is stably placed at the bottom of the sliding groove 113, providing a solid foundation for the entire lifting structure. When the second screw rod 810 rotates, its thread interacts with the second threaded hole 621 of the sliding member 620 to generate a driving force, causing the sliding member 620 to slide on the base 610 along a specific direction.

[0080] As the sliding member 620 slides, the included angle between the first support rod 631 and the second support rod 632 of the scissor fork 630 hinged thereto changes. Since one end of the first support rod 631 is hinged to the base 610 and one end of the second support rod 632 is hinged to the sliding member 620, this change in the included angle will drive the support platform 640 to move up or down. And the second universal ball rolling platform 700 for assisting the movement of the mold is installed on the support platform 640 and changes its height as the support platform 640 moves up and down.

[0081] This scissor fork 630 - type lifting structure has high stability and load - bearing capacity, and can reliably support the weight of the second universal ball rolling platform 700 and the mold. By precisely driving the sliding member 620 to slide through the second screw rod 810, precise control of the lifting height of the support platform 640 is achieved, meeting the requirement that the second universal ball rolling platform 700 needs to be at the same height as the first universal ball rolling platform 500.

[0082] Refer to Figures 3 - 4 , further, the second screw rod 810 has a plurality of thread segments 811 distributed at intervals, and the thread segments 811 are used for threaded connection with the second threaded holes 621; further includes a first elastic member 650, with both ends of the first elastic member 650 respectively arranged on the base 610 and the sliding member 620, and the first elastic member 650 is used to provide a force for the sliding member 620 to slide close to the thread segment 811; the third screw rod 820 is in transmission connection with the second screw rod 810, the third screw rod 820 is in threaded connection with the sliding frame 213, and the third screw rod 820 is used to drive the sliding frame 213 to slide.

[0083] In this embodiment, the second screw rod 810 has a plurality of thread segments 811 distributed at intervals, and each thread segment 811 is respectively in threaded connection with the second threaded hole 621 of a sliding member 620. In addition, a first elastic member 650 is provided, with both ends thereof respectively installed on the base 610 and the sliding member 620. The first elastic member 650 can provide a force for the sliding member 620 to slide close to the thread segment 811. When the driving device of the second screw rod 810 drives the second screw rod 810 to rotate forward, the sliding member 620 moves relative to the base 610 under the action of the thread segment 811, so that the support platform 640 rises. After the support platform 640 rises to the specified height, the sliding member 620 slides away from the thread segment 811, and the support platform 640 stops rising.

[0084] Meanwhile, the third screw rod 820 is in driving connection with the second screw rod 810, and the third screw rod 820 is in threaded connection with the sliding frame 213. The third screw rod 820 is used to drive the sliding frame 213 to slide. During actual operation, the rotation of the second screw rod 810 drives the third screw rod 820 to rotate through transmission, and the third screw rod 820 drives the sliding frame 213 to slide through the threaded connection with the sliding frame 213. After placing the mold on the extension frame 200, adjust the top plate 220 to a position where it can abut against the side of the mold, and start the driving device of the second screw rod 810. While the first lifting frame 600 rises, the top plate 220 pushes the mold to move towards the platform 111. Under the action of the threaded section 811, the first lifting frame 600 first rises to a predetermined height and stops, and the top plate 220 continues to push the mold to move towards the platform 111. After the sliding seat 210 slides to the limit position, the second screw rod 810 stops rotating, and the top plate 220 is adjusted to push the mold to the installation position.

[0085] Both ends of the first elastic member 650 are respectively arranged on the base 610 and the sliding member 620. During the process of the sliding seat 210 moving to raise the support platform 640, the first elastic member 650 is compressed. After the sliding member 620 leaves the threaded section 811, the first elastic member 650 always pushes the sliding member 620 to approach the threaded section 811. However, due to the problem of the rotation direction of the second screw rod 810, the sliding member 620 cannot re-enter the threaded section 811. After the mold moves to the installation position, the top plate 220 can be driven away from the mold by driving the second screw rod 810 to reverse. Under the action of the first elastic member 650, the sliding member 620 re-engages with the threaded section 811 and slides in the opposite direction, causing the support platform 640 to descend.

[0086] It should be further noted that when the second screw rod 810 rotates forward, after the sliding member 620 leaves the threaded section 811, it will generate slight reciprocating sliding under the dual action of the first elastic member 650 and the threaded section 811 on the second screw rod 810, so that the height of the support platform 640 fluctuates. Therefore, the meshing length between the threaded section 811 and the sliding member 620 should fit the depth of the first universal ball bearing table 500 and the chute 113, so that the fluctuating height of the support platform 640 is maintained between the surface of the first universal ball bearing table and the platform 111.

[0087] This design enables the lifting of the support platform 640 and the movement of the mold to be coordinated, improving work efficiency. The setting of the first elastic member 650 helps with different matching forms between the sliding member 620 and the spaced threaded sections 811.

[0088] Refer to Figures 5 - 8, Further, one end of the second screw 810 close to the extension frame 200 has a first driving projection 812, and one end of the third screw 820 close to the second screw 810 has a second driving projection 821. A connecting sleeve 900 is also included. The connecting sleeve 900 is slidably arranged on the third screw 820. Both ends of the connecting sleeve 900 have driving grooves 910 for driving connection with the first driving projection 812 and the second driving projection 821. Both ends of the second elastic member 920 are respectively arranged on the third screw 820 and the connecting sleeve 900. The second elastic member 920 is used to provide a force for the connecting sleeve 900 to slide close to the second screw 810.

[0089] In this embodiment, when the second screw 810 rotates, through the cooperation of the first driving projection 812 and the driving groove 910 at one end of the connecting sleeve 900, the connecting sleeve 900 is driven to rotate. At the same time, under the action of the second elastic member 920, on the one hand, it can prevent the connecting sleeve 900 from disengaging from the second screw 810, and on the other hand, it can make the connecting sleeve 900 slide away from the second screw 810 by squeezing the second elastic member 920, so as to release the driving connection between the second screw 810 and the third screw 820, enabling the third screw 820 to rotate and be received on the side of the bracket 110 following the extension rod.

[0090] Through the cooperation of the connecting sleeve 900 and the elastic member, the stable transmission of power is realized, and the energy loss during the transmission process is reduced. The cooperation mode of the first driving projection 812, the second driving projection 821 and the driving groove 910 increases the reliability and accuracy of the transmission and reduces the failure rate. The setting of the second elastic member 920 not only ensures the tight connection between the connecting sleeve 900 and the second screw 810 and the third screw 820, avoids loosening and slipping phenomena, improves the transmission efficiency, but also enhances the convenience of releasing the transmission between the connecting sleeve 900 and the second screw 810.

[0091] A stamping method for automotive parts includes:

[0092] S10: Rotate the extension frame 200 to a state parallel to the platform 111, and add an inclined support between the extension frame 200 and the bracket 110;

[0093] S20: Place the mold on the extension frame 200 and adjust the height of the lifting member 214 so that the top plate 220 can push the mold;

[0094] S30: Slide the connecting sleeve 900 so that the third screw 820 is in driving connection with the second screw 810 through the connecting sleeve 900;

[0095] S40: Start the driving device of the second screw 810. The second screw 810 drives the first lifting frame 600 to rise, and at the same time, the third screw 820 drives the top plate 220 to push the mold closer to the platform 111;

[0096] S50: After the sliding member 620 of the first lifting frame 600 disengages from the threaded section 811, the first lifting member 214 stops rising, and the top plate 220 continues to push the mold closer to the platform 111 until the sliding frame 213 slides to the extreme position;

[0097] S60: Rotate the first screw rod 300 to make the top plate 220 slide relative to the sliding frame 213, thereby pushing the mold to the installation position;

[0098] S70: Start the driving device of the second screw rod 810 again to reverse the second screw rod 810, and the first lifting frame 600 descends, and the sliding frame 213 drives the top plate 220 away from the mold;

[0099] S80: Fix the upper mold and the lower mold on the lower pressing plate 112 and the platform 111 respectively, and start the hydraulic system for stamping operation.
