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.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1~Figure 2 The present invention proposes an automobile parts stamping equipment, including a bracket 110, the bracket 110 has a platform 111, the platform 111 is used to support the lower mold, the lower pressing plate 112 is lifted and lowered on the bracket 110, the lower pressing plate 112 is used to support the upper mold, and also includes an extension frame 200, the extension frame 200 is rotatably set on the bracket 110, and the extension frame 200 is parallel to the platform 111 after rotation; a sliding seat 210 is slidably set on the extension frame 200, and the sliding seat 210 slides close to or away from the platform 111; a top plate 220 is slidably set 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 mold close to the platform 111, and the top plate 220 is used to push the mold into an installation position.

[0024] In this embodiment, the extension frame 200 is rotatably arranged on the bracket 110, and can remain parallel to the platform 111 after rotation. The extension frame 200 avoids the lower pressing plate 112, so that the mold can be placed on the extension frame 200 by lifting, and the rotating extension frame 200 can be stored on the side of the bracket 110, which can save 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 oblique support hinged below the rotation axis of the extension frame 200, and the abutment points of the extension frame 200 and the oblique support are plugged together by a latch. The oblique support, the bracket 110, and the extension frame 200 form a stable tripod shape, which not only has good stability, but also has less modification to the original stamping equipment and low modification cost. The sliding seat 210 can slide on the extension frame 200 by means of a slide rail or a slide groove 113, and can move closer to or 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 .

[0025] 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 re-placed on the platform 111, the extension frame 200 is first rotated to a position parallel to the platform 111, and then the mold is placed on the extension frame 200 through the overhead crane, and the driving device drives the sliding seat 210 to slide, 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 the slide groove 113, the sliding seat 210 stops sliding. The operator can slide the top plate 220 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 sliding of the sliding seat 210 can realize the movement of the mold, 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 to prevent the operator from using too much force to cause the mold to move beyond the installation position.

[0026] This design makes it easier to lift and place the mold, and improves the efficiency of mold change. The step-by-step movement of the sliding seat 210 and the top plate 220 can accurately control the position of the mold, ensuring that the mold is accurately installed in place, solving the problem of difficult positioning during mold change. It avoids repeated adjustments caused by inaccurate mold installation positions, saving time and labor costs.

[0027] Reference Figure 1~Figure 2 Further, the sliding seat 210 has a first threaded hole 211 and a plurality of support holes 212, and also includes a first screw rod 300, one end of the first screw rod 300 is rotatably set on the top plate 220, and the other end passes through the first threaded hole 211, and the first screw rod 300 is threadedly connected with the first threaded hole 211; there are a plurality of support columns 400, one end of which is set on the top plate 220, and the other end passes through the support hole 212, and the support column 400 is slidably set relative to the support hole 212, and the axis of the support column 400 is parallel to the axis of the first screw rod 300.

[0028] 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 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, thereby more accurately pushing the mold into the installation position. A rotating handle is provided at one end of the first screw 300 away from the top plate 220, which is convenient for the operator to operate. Through the threaded connection between the first screw 300 and the sliding seat 210, it further plays a labor-saving role.

[0029] In actual operation, the operator holds the rotating handle and easily rotates the first screw 300, driving the top plate 220 to smoothly push the mold, ensuring that the mold reaches the installation position accurately, avoiding mold position deviation caused by inaccurate human pushing, and improving the accuracy and efficiency of mold installation. The threaded connection between the first screw 300 and the sliding seat 210 combined with the guidance of the support column 400 realizes precise control of the movement of the top plate 220, improves the accuracy and stability of mold installation, and can also be applied to molds of different sizes.

[0030] Reference Figure 1~2 Further, the sliding seat 210 includes a sliding frame 213, which is slidably set on the extension frame 200. After the sliding frame 213 slides, it approaches or moves away from the platform 111; the lifting member 214 is lifted and lowered on the sliding frame 213, and the top plate 220 is slidably set on the lifting member 214. The highest point of the top plate 220 is not higher than 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.

[0031] 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 slide groove 113. The lifting member 214 is lifted and lowered on the sliding frame 213 by means of a lead screw. As the lifting member 214 descends, the height of the top plate 220 and the lifting member 214 is lowered from the top surface of the extension frame 200. In this way, it is avoided that the mold is pressed on the top plate 220 when the mold is placed on the extension frame 200. Moreover, by lowering the height of the top plate 220 and the lifting member 214, the mold cart can also be brought into contact with the extension frame 200, and the mold can be pushed onto the extension frame 200 by pushing.

[0032] After the mold is placed on the extension frame 200, the operator rotates the lead screw to make the lifting member 214 drive the top plate 220 to rise, so that the top plate 220 can contact the side 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 the mold position adjustment, and can better adapt to 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 position 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 in the designated position. The lifting and lowering of the lifting member 214 is controlled by the lead screw, which is simple and accurate to operate, reduces the difficulty of operation, and improves work efficiency. Avoiding the mold from being pressed on the top plate 220 and facilitating the mold cart to push and place the mold increases the convenience and safety of operation.

[0033] Reference Figure 1~Figure 3Furthermore, it also includes a first universal ball roller table 500, which 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 roller table 500 is not lower than the platform 111, and the first universal ball roller table 500 is used to abut against the bottom of the mold.

[0034] In this embodiment, in actual operation, when the mold is placed on the extension frame 200, the first universal ball roller table 500 can support the mold and reduce friction, so that the mold can move more smoothly on the extension frame 200. In addition, the first universal ball roller 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 lifting and placing the mold. As for the lateral positioning of the mold during the movement process, the positioning plate controlled by the lead screw on the platform 111 can be relied on to complete the lateral positioning of the mold after the mold is abutted against the positioning plate. The positioning plate relies on the movement of the lead screw to not only accurately adjust the position and control it, but also can be applied to molds of different sizes.

[0035] The first universal ball bearing platform 500 reduces the friction resistance between the mold and the extension frame 200, making the movement of the mold easier and more flexible. It helps to improve the efficiency of adjusting the position of the mold on the extension frame 200, reduce operation time and labor intensity, and better protect the bottom of the mold to avoid wear or damage during movement.

[0036] Reference Figure 3~Figure 4 Further, the platform 111 has a slide groove 113, and also includes a first lifting frame 600. The first lifting frame 600 is set in the slide groove 113 for lifting and lowering. After the first lifting frame 600 is lifted and lowered, it extends out of or enters the slide groove 113; the second universal ball rolling platform 700 is set on the first lifting frame 600. After the first lifting frame 600 rises, the height of the second universal ball rolling platform 700 is the same as the height of the first universal ball rolling platform 500. The first universal ball rolling platform 500 and the second universal ball rolling platform 700 are both used for mold movement.

[0037] 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 table 700 and the first universal ball 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 located at the installation position, the first lifting frame 600 descends and enters the slide groove 113, so that the mold can be stably placed on the platform 111.

[0038] The first lifting frame 600 and the second universal ball bearing platform 700 further optimize the mobility of the mold on the platform 111, and improve the convenience and fluency of operation. It ensures a smooth transition of the mold from the extension frame 200 to the platform 111, and reduces the jamming and position deviation caused by height difference or discontinuous support. It can adapt to molds of different sizes and shapes, and enhances the versatility and applicability of the equipment.

[0039] Reference Figure 3~Figure 4 Furthermore, there are several first lifting frames 600, and each of the several first lifting frames 600 is used to support the second universal ball table 700. The first lifting frame 600 is a screw lifting frame, and also includes a second screw 810. The second screw 810 is rotatably set on the bracket 110, and the second screw 810 is used to drive the several first lifting frames 600 to lift and lower.

[0040] In this embodiment, there are several first lifting frames 600, and these first lifting frames 600 are used to support the second universal ball roller table 700. Multiple first lifting frames 600 support together, which improves the stability and reliability of the support for the second universal ball roller table 700. To overcome the defects that the size of the slide groove 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, the width of the slide groove 111 does not exceed 15 cm. The first lifting frame 600 is a screw lifting frame. By rotating the second screw 810, it can drive multiple first lifting frames 600 to rise and fall synchronously at the same time, thereby realizing the lifting action of the second universal ball roller table 700. The driving mode of the screw lifting frame and the second screw 810 makes the lifting action accurate and smooth, and can realize the synchronous action of multiple lifting frames, ensuring the consistency of the lifting of the second universal ball roller table 700.

[0041] Reference Figure 3~Figure 4 Further, the first lifting frame 600 includes a base 610, which is arranged at the bottom of the slide groove 113; the sliding member 620 is slidably arranged on the base 610, and the sliding member 620 has a second threaded hole 621, and the second screw 810 is used to drive the sliding member 620 to slide; the scissors 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 hingedly arranged on the base 610, and one end of the second support rod 632 is hingedly arranged on the sliding member 620; the other end of the first support rod 631 of the support platform 640 is hingedly arranged on the support platform 640, and the other end of the second support rod 632 is hingedly and slidably arranged on the support platform 640. After the sliding member 620 slides, the support platform 640 rises or falls, and the second universal ball roller table 700 is arranged on the support platform 640.

[0042] In this embodiment, when the first lifting frame 600 is working, the base 610 is firmly placed at the bottom of the slide slot 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, so that the sliding member 620 slides on the base 610 along a specific direction.

[0043] As the sliding member 620 slides, the 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 on the base 610, and one end of the second support rod 632 is hinged on the sliding member 620, the change of the angle will drive the support platform 640 to rise or fall. The second universal ball bearing platform 700 used to assist the movement of the mold is installed on the support platform 640, and changes its height as the support platform 640 rises and falls.

[0044] 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 roller table 700 and the mold. The second screw 810 accurately drives the sliding member 620 to slide, thereby achieving precise control of the lifting height of the support table 640, meeting the requirement that the second universal ball roller table 700 needs to be in the same height as the first universal ball roller table 500.

[0045] Reference Figure 3~Figure 4 Furthermore, the second screw 810 has a plurality of spaced-apart thread segments 811, and the thread segments 811 are used to be threadedly connected to the second threaded hole 621; it also includes a first elastic member 650, and the two ends of the first elastic member 650 are 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 segments 811; the third screw 820 is transmission-connected to the second screw 810, and the third screw 820 is threadedly connected to the sliding frame 213, and the third screw 820 is used to drive the sliding frame 213 to slide.

[0046] In this embodiment, the second screw rod 810 has a plurality of threaded segments 811 distributed at intervals, and each threaded segment 811 is respectively threadedly connected to a second threaded hole 621 of a sliding member 620. In addition, a first elastic member 650 is provided, and its two ends are respectively mounted on the base 610 and the sliding member 620. The first elastic member 650 can provide a force to make the sliding member 620 slide close to the threaded 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 threaded segment 811, thereby raising the support platform 640. After the support platform 640 rises to a specified height, the sliding member 620 slides away from the threaded segment 811, and the support platform 640 stops rising.

[0047] At the same time, the third screw 820 is connected to the second screw 810 by transmission, and the third screw 820 is threadedly connected to the sliding frame 213, and the third screw 820 is used to drive the sliding frame 213 to slide. In actual operation, the rotation of the second screw 810 drives the third screw 820 to rotate through transmission, and the third screw 820 drives the sliding frame 213 to slide through the threaded connection with the sliding frame 213. After the mold is placed on the extension frame 200, the top plate 220 is adjusted to a position where it can abut against the side of the mold, and the driving device of the second screw 810 is started. While the first lifting frame 600 rises, the top plate 220 pushes the mold to move in the direction close to 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 in the direction close to the platform 111. After the sliding seat 210 slides to the limit position, the second screw 810 stops rotating, and the top plate 220 is adjusted to push the mold to the installation position.

[0048] The two ends of the first elastic member 650 are respectively arranged on the base 610 and the sliding member 620. When the sliding seat 210 moves 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 second screw 810 turning, the sliding member 620 cannot re-enter the threaded section 811. After the mold moves to the installation position, the second screw 810 can be driven by the driving device to reverse, so that the top plate 220 is away from the mold. 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 to lower the support platform 640.

[0049] It should be further explained that when the sliding member 620 leaves the threaded segment 811 when the second screw 810 rotates forward, it will produce a slight reciprocating sliding under the dual action of the first elastic member 650 and the threaded segment 811 on the second screw 810, thereby causing the height of the support platform 640 to fluctuate. Therefore, the engagement length of the threaded segment 811 and the sliding member 620 should match the depth of the first universal ball platform 500 and the slide groove 113, so that the fluctuating height of the support platform 640 is maintained between the first universal ball platform and the surface of the platform 111.

[0050] This design enables the lifting and lowering of the support platform 640 and the movement of the mold to be coordinated, thereby improving work efficiency. The provision of the first elastic member 650 facilitates different matching forms between the sliding member 620 and the threaded segments 811 disposed at intervals.

[0051] Reference Figure 5~Figure 8Furthermore, the second screw 810 has a first transmission protrusion 812 at one end close to the extension frame 200, and the third screw 820 has a second transmission protrusion 821 at one end close to the second screw 810, and also includes a connecting sleeve 900, which is slidably arranged on the second screw 810, and has transmission grooves 910 at both ends of the connecting sleeve 900, and the transmission grooves 910 are used for transmission connection with the first transmission protrusion 812 and the second transmission protrusion 821; the second elastic member 920 is respectively arranged on the third screw 820 and the connecting sleeve 900, and the second elastic member 920 is used to provide a force for the connecting sleeve 900 to slide close to the second screw 810.

[0052] In this embodiment, when the second screw rod 810 rotates, the first transmission protrusion 812 cooperates with the transmission groove 910 at one end of the connection sleeve 900 to drive the connection sleeve 900 to rotate. At the same time, under the action of the second elastic member 920, on the one hand, the sliding sleeve can be prevented from being separated from the second screw rod 810, and on the other hand, the sliding sleeve can be squeezed by squeezing the second elastic member 920 to slide away from the second screw rod 810, thereby releasing the transmission connection between the second screw rod 810 and the third screw rod 820, so that the third screw rod 820 can rotate with the extension rod and be stored on the side of the bracket 110.

[0053] Through the cooperation of the connecting sleeve 900 and the elastic member, the stable transmission of power is achieved, and the energy loss in the transmission process is reduced. The cooperation mode of the first transmission protrusion 812, the second transmission protrusion 821 and the transmission 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 looseness and slippage, improves the transmission efficiency, but also improves the convenience of releasing the transmission between the sliding sleeve and the second screw 810.
