Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to a mold adjustment device for a gantry press. Background Technology

[0002] Gantry presses are widely used in industrial production for stamping and forming of various metal and non-metal materials. During the operation of the press, the installation and adjustment of the dies are crucial. The adjustment of the distance between the upper and lower dies directly affects the processing accuracy and quality of the product. Some presses use hydraulic cylinders to adjust the height of the lower worktable to achieve this adjustment. Because the lower worktable relies solely on the hydraulic cylinders for support during operation, the cylinders bear enormous pressure. Prolonged operation under such high pressure can easily damage the sealing performance of the hydraulic cylinders, leading to hydraulic oil leakage and affecting the normal operation of the press. If the hydraulic cylinders malfunction, it may cause the lower worktable to suddenly sink or shift, damaging the dies and potentially causing safety accidents, threatening the lives of the operators.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-6This is the first embodiment of the present utility model. This embodiment provides a gantry press mold adjustment device. The gantry press mold adjustment device includes a main component 100, including a frame 101, a lower worktable 102 and a first oil cylinder 103. The frame 101 has a cavity 101-1. The lower worktable 102 is located in the cavity 101-1. The first oil cylinder 103 is located below the first oil cylinder 103.

[0030] The first hydraulic cylinder 103 is used to precisely adjust the position of the lower worktable 102 so as to adjust the height of the lower worktable 102 and realize the adjustment of the distance between the upper and lower molds to adapt to the installation requirements of different molds. One end of the first hydraulic cylinder 103 is fixed with a fixing plate 106, which is bolted to the lower worktable 102. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0031] The support assembly 200 is located below the first hydraulic cylinder 103 and includes a support member 201. The support member 201 includes a threaded rod 201a, a clamping plate 201b, an ear plate 201c, and a fixed shaft 201d. The threaded rod 201a is connected to the bottom bearing of the lower worktable 102. The clamping plate 201b is located outside the threaded rod 201a. The ear plate 201c is fixed on the clamping plate 201b. The ear plate 201c has a through hole 201c-1, and the fixed shaft 201d is inserted into the through hole 201c-1.

[0032] The support member 201 is used to provide auxiliary support for the lower worktable 102. There are two sets of support members 201, which are symmetrically distributed at the bottom of the lower worktable 102 to improve the support stability of the lower worktable 102.

[0033] The clamping plate 201b is arc-shaped, and the ear plate 201c can move along the fixed shaft 201d. The two clamping plates 201b clamp the threaded rod 201a from both sides to prevent it from moving vertically due to vibration or other external forces during the operation of the press.

[0034] The support assembly 200 also includes a locking element 202, which is disposed on one side of the clamping plate 201b and includes a movable plate 202a, a pressing plate 202b and a force-bearing block 202c. A through groove 101-2 is provided on the frame 101. The movable plate 202a is inserted into the through groove 101-2, the pressing plate 202b is fixed to one end of the movable plate 202a, and the force-bearing block 202c is fixed on the clamping plate 201b.

[0035] By setting the locking element 202, after the clamping plate 201b and the threaded rod 201a are fully engaged, the position of the clamping plate 201b is locked to ensure that the position of the clamping plate 201b will not shift.

[0036] One end of the force-bearing block 202c is inclined. When the moving plate 202a is pushed to move the pressing plate 202b toward the force-bearing block 202c, the inclined surface of the force-bearing block 202c will be pressed by the pressing plate 202b, thereby causing the force-bearing block 202c to move toward the threaded rod 201a, and then causing the clamping plate 201b to move toward the threaded rod 201a, so that the two are tightly fitted together.

[0037] Example 2

[0038] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the frame 101 has a moving groove 101-3, and a locking block 202d is provided in the moving groove 101-3. A first spring 202e is fixed to one end of the locking block 202d.

[0040] The locking block 202d is configured to restrict the movement of the moving plate 202a, and the first spring 202e applies a continuous thrust to the locking block 202d.

[0041] Specifically, a locking groove 202a-1 is provided in the movable plate 202a, and the locking block 202d can engage with the locking groove 202a-1.

[0042] When the locking block 202d engages with the locking groove 202a-1, the moving plate 202a will be unable to move further due to their cooperation. At this time, the pressing plate 202b presses the force-bearing block 202c, causing the clamping plate 201b to fit tightly with the threaded rod 201a. In the initial state, the locking block 202d and the locking groove 202a-1 are not engaged.

[0043] A push plate 202g is fixed on one side of the locking block 202d. The push plate 202g is used to unlock the locking block 202d from the locking groove 202a-1. When unlocking is required, the push plate 202g is pushed to compress the first spring 202e, thereby separating the locking block 202d from the locking groove 202a-1, so that the moving plate 202a can move again.

[0044] Specifically, the clamping plate 201b has a threaded groove 201b-1 corresponding to the threaded rod 201a, and the threaded groove 201b-1 can engage with the threaded rod 201a.

[0045] By setting the corresponding threaded groove 201b-1, when the threaded groove 201b-1 can be fully engaged with the threaded rod 201a, since the clamping plate 201b will not move in the vertical direction and its horizontal position is locked, the horizontal position of the threaded rod 201a will also be locked, thereby providing auxiliary support for the lower worktable 102.

[0046] A window 101-4 is provided on one side of the frame 101. The window 101-4 is hinged to the frame 101. When the clamping plate 201b approaches the threaded rod 201a, the window 101-4 is opened. The threaded rod 201a is slightly rotated from the window 101-4. If the threaded rod 201a can be rotated, it means that the threaded groove 201b-1 on the clamping plate 201b is not completely engaged with the threaded rod 201a. The rotation of the threaded rod 201a is adjusted in a small range until it cannot be rotated. At this time, the threaded groove 201b-1 engages with the threaded rod 201a, which can quickly and firmly lock the position of the threaded rod 201a and prevent it from moving vertically due to vibration or other external forces during the operation of the press. Thus, with the cooperation of the threaded rod 201a, clamping plate 201b, support column 201f and fixing block 201i, the lower worktable 102 is provided with auxiliary support, which effectively reduces the working pressure and wear of the first oil cylinder 103.

[0047] Specifically, the threaded rod 201a can engage with both clamping plates 201b simultaneously.

[0048] By setting two clamping plates 201b, the threaded rod 201a can be completely wrapped when the two are in contact, thereby ensuring that the threaded groove 201b-1 and the threaded rod 201a are fixed in position.

[0049] Specifically, a second spring 201e is sleeved on the fixed shaft 201d, and one end of the second spring 201e is fixed to the ear plate 201c.

[0050] The second spring 201e is fixed at both ends to the ear plate 201c. When the two clamping plates 201b approach each other, the second spring 201e will be compressed. When the moving plate 202a is unlocked, the second spring 201e will return to its original state, thereby driving the clamping plate 201b to move away from the threaded rod 201a. This causes the force block 202c to push the pressing plate 202b to move, causing the moving plate 202a to move away from the force block 202c and return to its initial position.

[0051] Example 3

[0052] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0053] Specifically, support columns 201f are fixed on both sides of the fixed shaft 201d.

[0054] A fixing block 201i is fixed inside the chamber 101-1. The bottom of the support column 201f is fixed to the fixing block 201i. The support column 201f supports and positions the fixing shaft 201d, which in turn supports the clamping plate 201b.

[0055] Specifically, the movable plate 202a is covered with a first support block 201g, and the extrusion plate 202b is covered with a second support block 201h.

[0056] The bottoms of the first support block 201g and the second support block 201h are both fixed to the second support block 201h, thereby providing stable support for the moving plate 202a and the pressing plate 202b, and ensuring that the moving plate 202a and the pressing plate 202b can only move in a specific direction.

[0057] Specifically, a guide post 202f is fixed to the inner wall of the moving groove 101-3, and a guide groove 202d-1 is opened on the locking block 202d. The guide post 202f can engage with the guide groove 202d-1.

[0058] The cooperation between the guide post 202f and the guide groove 202d-1 ensures that the locking block 202d can move smoothly within the moving groove 101-3.

[0059] Specifically, the main component 100 also includes a second hydraulic cylinder 104 and an upper worktable 105. The second hydraulic cylinder 104 is fixed on the frame 101, and the upper worktable 105 is located on one side of the second hydraulic cylinder 104.

[0060] The second hydraulic cylinder 104 is used to drive the upper worktable 105 to achieve precise vertical movement. This is existing technology, and this solution will not elaborate further. Moreover, those skilled in the art can clearly understand the working principle.

[0061] The frame 101 is also fixed with four support legs 107 to ensure the stability of the frame 101.

[0062] In use, the position of the lower worktable 102 is precisely adjusted by the first hydraulic cylinder 103. Then, when the moving plate 202a is pushed to move the pressing plate 202b towards the force-bearing block 202c, the inclined surface of the force-bearing block 202c will be pressed by the pressing plate 202b, causing the force-bearing block 202c to move towards the threaded rod 201a. This, in turn, causes the clamping plate 201b to move towards the threaded rod 201a, making them fit tightly together. At this point, the window 101-4 is opened, and the threaded rod 201a is slightly rotated from the window 101-4. If the threaded rod 201a can be rotated, it indicates that the threaded groove 201b-1 on the clamping plate 201b is not... Completely fit with the threaded rod 201a, the rotation of the threaded rod 201a is adjusted within a small range until it can no longer rotate. At this time, the threaded groove 201b-1 engages with the threaded rod 201a, thereby locking the position of the threaded rod 201a and preventing it from moving vertically due to vibration or other external forces during the operation of the press. Under the restriction of the threaded groove 201b-1, the threaded rod 201a will not rotate. Thus, with the cooperation of the threaded rod 201a, the clamping plate 201b, the support column 201f, and the fixing block 201i, auxiliary support is provided for the lower worktable 102, effectively reducing the working pressure and wear of the first oil cylinder 103.

[0063] Simultaneously, when the threaded groove 201b-1 engages with the threaded rod 201a, as the moving plate 202a moves, the locking groove 202a-1 will move to a position coaxial with the locking block 202d. Under the push of the first spring 202e, the two engage, thereby restricting the movement of the moving plate 202a and ensuring that the clamping plate 201b is always in close contact with the threaded rod 201a.

[0064] When it is necessary to separate the clamping plate 201b from the threaded rod 201a, the push plate 202g is pushed to compress the first spring 202e, thereby separating the locking block 202d from the locking groove 202a-1, so that the moving plate 202a can move again. When the moving plate 202a is unlocked, the second spring 201e will return to its original state, thereby driving the clamping plate 201b to move away from the threaded rod 201a, thereby causing the force block 202c to push the pressing plate 202b to move, causing the moving plate 202a to move away from the force block 202c and return to the initial position.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
