[0001] This utility model relates to the field of press technology, specifically to a buffer-type upper die connection structure for a press. Background Technology

[0002] Currently, for the upper die process of stamping parts or dies used in large press stamping operations, electric hoists or other lifting tools are usually used to place them on the press base of the press. However, due to the characteristics of press stamping operations, the stamping part is often located above the press base, which affects the upper die operation of the hoisted stamping parts on the press base, increasing the difficulty of operation and reducing the operating efficiency of the press. Utility Model Content

[0003] The purpose of this utility model is to provide a buffer-type upper die connection structure for a press. This connection structure can further improve the convenience and efficiency of upper and lower die operations on the press base without affecting the normal stamping process.

[0004] The technical solution adopted by this utility model to solve the above problems is: A buffer-type upper die connection structure for a press includes a press body and an upper die assembly mounted on a press base. The upper die assembly includes multiple sets of first connecting frames and second connecting frames that are detachably installed in multiple sets of sliding grooves located on one side of the press base and on the press base, respectively. Multiple sets of first guide wheels and second guide wheels that are rotatably arranged at intervals are respectively mounted on the first connecting frames and the second connecting frames.

[0005] Preferably, the first connecting frame is detachably connected to the pressure seat via a connecting seat that is detachably installed at one end.

[0006] Preferably, the upper mold assembly further includes a third connecting frame that is detachably connected to the pressure seat on one side corresponding to the position of the first connecting frame via a second connecting frame. A third guide wheel is rotatably mounted on the third connecting frame, and the rotation direction of the third guide wheel is perpendicular to that of the first guide wheel. The second connecting seat is provided with an adjustment part for adjusting the height of the third connecting frame. The adjustment part includes a connecting plate slidably mounted on the second connecting seat and a connecting rod located below the connecting plate and rotatably mounted on the second connecting seat.

[0007] Preferably, a fourth connecting frame is also installed on the other side of the pressure seat away from the upper mold assembly, which is detachably connected to the pressure seat via a third connecting seat. A first baffle and a second baffle are slidably arranged on the fourth connecting frame. The first baffle slides on one side of the second baffle via a second connecting rod provided thereon and a compression spring sleeved on its outer side. A locking member for position locking is rotatably arranged on the second baffle.

[0008] Compared with the prior art, this utility model has the following advantages and effects: This utility model relates to a buffer-type upper die connection structure for a press. This structure, while not affecting the normal stamping process, further improves the convenience and efficiency of upper and lower die operations on the press base for stamped parts. It offers high applicability and flexibility for stamped parts such as large and heavy components or molds, facilitating operation and effectively improving the overall operating efficiency of the press. Furthermore, the height setting of the second guide wheel on the second connecting frame within the press base's groove allows for the movement of the stamped part.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0015] See Figure 1 This embodiment relates to a buffer-type upper die connection structure for a press, including an upper die assembly 1 installed on a press body 100 and a press base 101. The upper die assembly 1 includes multiple sets of first connecting frames 11 and second connecting frames 12 that are detachably installed in multiple sets of sliding grooves 102 respectively located on one side of the press base 101 and on the press base 101. Multiple sets of first guide wheels 111 and second guide wheels 121 are rotatably arranged on the first connecting frames 11 and the second connecting frames 12.

[0016] Specifically in this embodiment, such as Figure 1 The press body 100 and the upper die assembly 1 on the press base 101 are shown in the overall structural configuration. The press body 100 adopts one of the conventional structures commonly used in existing presses. The number of the first connecting frame 11 and the second connecting frame 12 can be set according to the usage requirements and the specifications of the stamped parts. Both can be installed on one side of the press base 101 and in the slide groove 102 respectively by bolt connections. Specifically, during the upper die process, the stamped parts hoisted by external lifting tools such as electric hoists can be placed on multiple sets of first connecting frames 11 on one side of the press base 101 with manual support. After the position of the stamped part on the first connecting frame 11 corresponding to the pressure seat 101 is adjusted by the hoisting tool, the connection with the hoisting tool is immediately disconnected. Then, the multiple sets of first guide wheels 111 and second guide wheels 121, which are respectively rotatably set on the first connecting frame 11 and the second connecting frame 12, are used to push the stamped part to the corresponding stamping position on the pressure seat 101, thus completing the upper die operation of the stamped part. At the same time, after the operation is completed, the stamped part on the pressure seat 101 is pushed outward along the multiple sets of first connecting frames 11 on one side of the pressure seat 101. Then, the lower die and switching operations of the stamped part are completed by the hoisting tool. The addition of a buffer-type upper die connection structure to this press does not affect the normal stamping operation process, but further improves the convenience and efficiency of upper and lower die operations on the press base 101 for stamped parts. It has high applicability and flexibility for stamped parts such as large and heavy parts or molds, and effectively improves the working efficiency of the press body 100 while facilitating operation. In addition, the corresponding height setting of the second guide wheel 121 on the second connecting frame 12 in the slide 102 of the press base 101 can realize the position movement of the stamped parts. Combined with the corresponding volume and weight of the stamped parts, it does not affect the normal operation process. Furthermore, conventional corrugated bow plates can also be added to the slide 102 of the press base 101. Combined with the arrangement of the third connecting frame 13, it further improves the speed of upper and lower die operations on the press base 101 for stamped parts, and can also further improve the support effect of the stamped parts, reducing the wear on the stamped parts and the corresponding walls of the press base 101.

[0017] The first connecting frame 11 is detachably connected to the pressure seat 101 via a connecting seat 14 detachably mounted at one end. Specifically, this can be combined with... Figure 2 and Figure 3 As shown, the connecting seat 14 is detachably installed on the pressure seat 101 by bolt connection. The structure of the first connecting frame 11 is designed to be detachably connected by a convex plate 112 at one end and a mounting groove 141 on the connecting seat 14. This allows for the installation of multiple sets of connecting seats 14 on one side of the pressure seat 101 and the detachable installation of multiple sets of first connecting frames 11 on the corresponding connecting seats 14, further improving the structural detachability of the upper mold assembly 1. The first connecting frame 11 can be installed, added, removed, and stored on the connecting seat 14 according to the specifications of the stamped part, meeting different operational requirements and usage needs.

[0018] The upper mold assembly 1 further includes a third connecting frame 13 that is detachably connected to the pressure seat 101 on one side of the pressure seat 101 corresponding to the position of the first connecting frame 11 via a second connecting seat 15. A third guide wheel 131 is rotatably mounted on the third connecting frame 13, and the rotation direction of the third guide wheel 131 is perpendicular to that of the first guide wheel 111. The second connecting seat 15 is provided with an adjustment part 150 for adjusting the height of the third connecting frame 13. The adjustment part 150 includes a connecting plate 154 slidably mounted on the second connecting seat 15 and a connecting rod 153 rotatably mounted on the second connecting seat 15 below the connecting plate 154. Specifically, the second connecting seat 15 is detachably mounted on the corresponding side of the pressure seat 101 via bolts. The second connecting seat 15 and the connecting seat 14 can be adjusted on one side of the pressure seat 101. Figure 1-3The installation is carried out in the manner described above. The structure of the third connecting frame 13 is designed to allow for a detachable connection process by sliding and engaging with the second mounting groove 151 on the second connecting seat 15, which is provided in two sets at one end. Simultaneously, the installation height of the third connecting frame 13 on the second connecting seat 15 can be adjusted by the adjusting part 150 to make it slightly higher than the first connecting frame 11. Specifically, the connecting plate 154 in the adjusting part 150 can be fitted and slidably engaged with the second sliding grooves 152 on the second connecting seat 15 corresponding to the second mounting groove 151 on both sides of its two ends via the third protrusions 155. The connecting plate 154 can be positioned below the third connecting frame 13 for padding, and the connecting rod 153 is located on the connecting plate 15. 4. The connecting plate 154 is rotatably mounted on the second connecting seat 15 via a threaded structure. Rotating the connecting rod 153 allows the connecting plate 154 to move up and down within the second mounting groove 151 under the abutment of the connecting rod 153, thus realizing the height adjustment process of the third connecting frame 13 on the second connecting seat 15. The stamped part, which is hoisted in conjunction with the hoisting tool, can be initially placed on the multiple sets of third connecting frames 13 mounted on the multiple sets of second connecting seats 15 on one side of the pressure seat 101. At the same time, combined with the height setting of the third connecting frame 13 on the second connecting seat 15 under the adjustment of the adjustment part 150, the third guide wheel 131, which is rotatably mounted on the third connecting frame 13 in the corresponding direction, can facilitate the left and right position of the stamped part on one side of the pressure seat 101. During the adjustment process, after the position adjustment is completed, the connecting rod 153 can be rotated so that the connecting plate 154 and the third connecting frame 13 can move downward a suitable distance along the second mounting groove 151 on the second connecting seat 15. At this time, the stamping part on the third connecting frame 13 can act on multiple sets of first connecting frames 11 as it moves downward, thereby pushing the stamping part to engage with multiple sets of first guide wheels 111 on the first connecting frame 11 and multiple sets of second guide wheels 121 on the second connecting frame 12 on the pressure seat 101 to adjust its front and rear position. The addition of the third connecting frame 13 and the second connecting seat 15 and the adjustment part 150 in the upper die assembly 1 can further improve the functional diversity of the upper die assembly 1 and improve the stamping part's ability to pass through the upper die assembly 1. The upper die assembly offers flexibility in position adjustment during the upper die process on the pressure seat 101. Furthermore, the third guide wheel 131 on the third connecting frame 13 can be configured with a rubber roller structure, providing cushioning and shock absorption when the stamped parts are pre-placed on the third connecting frame 13. This effectively reduces wear on the corresponding wall surfaces during left-right position adjustment of the stamped parts. Additionally, after the stamping operation is completed, additional conveyor belts or roller conveyors can be connected to the upper die assembly 1 on both sides along the rotation direction of the third connecting frame 13, facilitating the adjustment, transfer, and switching of the upper and lower dies on the pressure seat 101 of the press body 100 for batch stamped parts.This improves the flexibility, applicability, and practicality of the buffer-type upper die connection structure used in this type of press.

[0019] See Figure 4 Along the other side of the pressure seat 101 away from the upper mold assembly, a fourth connecting frame 3 is also installed, which is detachably connected to the pressure seat 101 via a third connecting seat 2. A first baffle 33 and a second baffle 34 are slidably mounted on the fourth connecting frame 3. The first baffle 33 slides on one side of the second baffle 34 via a second connecting rod 331 mounted thereon and a compression spring 332 sleeved on its outer side. A locking element 342 for position locking is rotatably mounted on the second baffle 34. Specifically, the third connecting seat 2 is structurally compatible with the first connecting seat 14 and is detachably mounted on the corresponding side of the pressure seat 101 via a bolt connecting frame, while the fourth connecting frame 3 is divided into two sections at one end. The fourth protruding plate 32 of the assembly is detachably connected by sliding and engaging with the third mounting groove 21 on the third connecting seat 2. The first baffle 33 and the second baffle 34 are adapted to slide in the third sliding groove 31 on the fourth connecting frame 3. The length of the second connecting rod 331 on the first baffle 33 is designed to pass through the adapting through hole 341 on the second baffle 34, and slide within the third sliding groove 31 of the fourth connecting frame 3 with the help of the compression spring 332 on one side of the second baffle 34. At the same time, the second baffle 34 can be locked with a bolt-connected frame structure. The part 342 is positioned within the third slide groove 31 (i.e., the sliding distance of the first baffle 33 within the third slide groove 31 is adjusted) and locked in the corresponding position. Specifically, when the stamped part is pushed onto the pressure seat 101, the first baffle 33 and the compression spring 332 sleeved around the second connecting rod 331 can provide a certain degree of resistance and buffering effect on the stamped part. Combined with the position limitation of the second baffle 34 on the fourth connecting frame 3, it can effectively reduce the phenomenon of the stamped part slipping and falling off the pressure seat 101, and improve operational safety. In addition, the fourth connecting frame 3 and the third slide groove 31 and the second connecting rod 342 can also be used to adjust the position of the stamped part. The length setting of 31 and the elastic strength of the compression spring 332 can be flexibly selected and adjusted according to actual usage requirements. Combined with the threaded structure on the connecting rod 153 and the flexible addition of multiple sets of nuts at the front and rear positions of the second baffle 34, as well as the flexible adjustment of the locking part 342 on the second baffle 34, the sliding distance of the corresponding first baffle 33 in the third slide groove 31 on the fourth connecting frame 3 can be flexibly adjusted, resulting in different buffering effects. At the same time, anti-slip pads can be attached to the corresponding wall surface of the first baffle 33 to reduce the probability of unnecessary damage to the surface of the stamped part during impact, and also effectively improve the buffering effect of the first baffle 33.
