Description

Technical Field

[0001] This utility model relates to the field of cold stamping die technology, and in particular to a large-diameter cylinder mounting structure. Background Technology

[0002] In the process of cold stamping die making, the side flange is usually achieved by using an interactive mechanism to remove the part. The power source of the interactive mechanism comes from a large-diameter cylinder installed on the lower die base. The piston rod of the large-diameter cylinder extends and retracts to drive the interactive mechanism.

[0003] Large-diameter cylinders are mounted to the lower mold base via angle brackets, which are L-shaped structures with vertical and horizontal sections. For example... Figure 1 As shown, in the mold, the lower mold base has a groove for installing a large-diameter cylinder, which is connected to the lower mold base via corner brackets. When installing the large-diameter cylinder, the corner brackets are connected to the lower mold base with bolts. The vertical part of the corner bracket rests against the large-diameter cylinder, while the horizontal part of the corner bracket is located on the side away from the large-diameter cylinder. This results in the large-diameter cylinder occupying a space equal to the sum of the length of the large-diameter cylinder, the thickness of the vertical part of the corner bracket, and the length of the horizontal part of the corner bracket, leading to a larger space requirement. Therefore, the outward orientation of the two corner brackets increases the installation space for the large-diameter cylinder, resulting in an increase in mold length and mold cost.

[0004] In addition, the large-diameter cylinder includes a cylinder body and a retractable piston rod mounted on the cylinder body. A piston connected to the piston rod is located inside the cylinder body. During installation, two corner seats are used, located on both sides of the large-diameter cylinder, with the piston rod's extension and retraction direction perpendicular to the vertical portions of the two corner seats. During operation, the piston moves within the large-diameter cylinder, continuously impacting the inner walls of the left and right sides. This force is transmitted to the bolts fixing the corner seats, causing them to break under tangential force. Furthermore, only the side of the horizontal portion of the corner seat contacts the lower mold base, meaning the side of the horizontal portion of the corner seat contacts the groove wall of the lower mold base. To limit the position of the large-diameter cylinder, a limiting block is also installed within the groove, located between the corner seat and the groove wall. Therefore, the contact area between the corner seat and the lower mold base is only the side of the horizontal portion of the corner seat, resulting in a small contact area and thus a small force-bearing area. This is insufficient to restrain the high-speed impact of the large-diameter cylinder piston, causing the large-diameter cylinder to sway from side to side. When a large-diameter cylinder wobbles left and right, the corner seat acts as a fulcrum, and the large-diameter cylinder rotates along its centerline. According to the principle of torque, the magnitude of the torque depends on the applied force and the length of the lever arm. Under the same force, if the installation structure of the large-diameter cylinder has a larger length, the torque generated will be larger, resulting in violent shaking of the large-diameter cylinder. Utility Model Content

[0007] The first corner seat includes a first vertical seat plate and a first horizontal seat plate, the first vertical seat plate being perpendicularly connected to the first horizontal seat plate; the second corner seat includes a second vertical seat plate and a second horizontal seat plate, the second vertical seat plate being perpendicularly connected to the second horizontal seat plate; the first horizontal seat plate and the second horizontal seat plate are connected to the lower mold base by the mounting bolts.

[0008] The first and second corner seats are located on both sides of the large-diameter cylinder, and the first and second corner seats are mirror images of each other, such that the first horizontal seat plate and the second horizontal seat plate are located between the first vertical seat plate and the second vertical seat plate, the large-diameter cylinder is located between the first vertical seat plate and the second vertical seat plate, and the large-diameter cylinder is located above the first horizontal seat plate and the second horizontal seat plate.

[0010] As a preferred embodiment, the first corner seat is located on the side where the piston rod extends, and the first vertical seat plate is provided with a clearance notch.

[0011] As a preferred embodiment, the clearance gap is an arc-shaped gap.

[0012] As a preferred embodiment, the lower mold base is provided with a first mounting hole, and both the first horizontal seat plate and the second horizontal seat plate are provided with a second mounting hole. The mounting bolt passes through the second mounting hole and is threadedly connected to the first mounting hole. The second mounting hole is an oblong hole.

[0013] As a preferred embodiment, the large-diameter cylinder includes a cylinder body and a piston rod, the piston rod being telescopically mounted on the cylinder body, and the length direction of the second mounting hole being parallel to the telescopic direction of the piston rod.

[0014] As a preferred embodiment, the cylinder further includes a locking shaft and a locking nut. The large-diameter cylinder includes a cylinder body and a piston rod. The piston rod is telescopically mounted on the cylinder body. The cylinder body has a first locking hole and a second locking hole, which are located on both sides of the cylinder body in the direction of piston rod extension. The first vertical seat plate has a third locking hole, and the second vertical seat plate has a fourth locking hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes a first and second corner seat, positioned mirror images of each other on either side of a large-diameter cylinder. The first horizontal plate of the first corner seat and the second horizontal plate of the second corner seat are positioned between a first and a second vertical plate, making the first and second corner seats face inwards. This ensures that the space required to mount the large-diameter cylinder on the lower mold base is the sum of the cylinder body length and the thicknesses of the first and second vertical plates. This reduces installation space, mold length, and mold costs. Furthermore, during installation, the first and second vertical plates contact the lower mold base, increasing the contact area and thus the force-bearing area, providing more stable restraint for the large-diameter cylinder. Additionally, the large-diameter cylinder is positioned above the first and second horizontal plates. According to the torque principle, this invention raises the position of the fulcrum, reducing the lever arm length. Under the same force, the torque on the cylinder is reduced, effectively solving the problem of large-diameter cylinder wobbling. Attached Figure Description

[0030] Example 1

[0031] like Figures 2 to 5 As shown, a preferred embodiment of the present invention provides a large-diameter cylinder mounting structure, including a large-diameter cylinder 1 and a lower mold base 2. The large-diameter cylinder 1 is mounted on the lower mold base 2. The structure also includes a first corner seat 3, a second corner seat 4, and mounting bolts 5. The first corner seat 3 includes a first vertical seat plate 301 and a first horizontal seat plate 302, with the first vertical seat plate 301 and the first horizontal seat plate 302 perpendicularly connected. The second corner seat 4 includes a second vertical seat plate 401 and a second horizontal seat plate 402, with the second vertical seat plate 401 and the second horizontal seat plate 402 perpendicularly connected. A horizontal seat plate 302 and a second horizontal seat plate 402 are connected to the lower mold base 2 by mounting bolts 5; a first corner seat 3 and a second corner seat 4 are located on both sides of the large-diameter cylinder 1, and the first corner seat 3 and the second corner seat 4 are mirror images of each other, so that the first horizontal seat plate 302 and the second horizontal seat plate 402 are located between the first vertical seat plate 301 and the second vertical seat plate 401, the large-diameter cylinder 1 is located between the first vertical seat plate 301 and the second vertical seat plate 401, and the large-diameter cylinder 1 is located above the first horizontal seat plate 302 and the second horizontal seat plate 402.

[0032] In this embodiment, a first corner seat 3 and a second corner seat 4 are positioned on either side of the large-diameter cylinder 1 and are mirror images of each other. Simultaneously, the first horizontal seat plate 302 of the first corner seat 3 and the second horizontal seat plate 402 of the second corner seat 4 are located between the first vertical seat plate 301 and the second vertical seat plate 401. This arrangement ensures that the first corner seat 3 and the second corner seat 4 face inwards, resulting in a space length on the lower mold base 2 equal to the sum of the length of the cylinder body 101 of the large-diameter cylinder 1 and the thickness of the first vertical seat plate 301 and the second vertical seat plate 401. This reduces the installation space, decreases the mold length, and saves mold costs. Furthermore, during installation, the first vertical seat plate 301 and the second vertical seat plate 401 contact the lower mold base 2, resulting in a large contact area and thus increasing the force-bearing area, providing a more stable restraint for the large-diameter cylinder 1. Furthermore, in this embodiment, the large-diameter cylinder 1 is located above the first horizontal seat plate 302 and the second horizontal seat plate 402. According to the torque principle, this embodiment improves the position of the fulcrum, making the lever arm length smaller. Under the same force, the torque on the cylinder is reduced, which can effectively solve the problem of the large-diameter cylinder 1 shaking.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, this embodiment further explains the mounting structure of the large-diameter cylinder.

[0035] In this embodiment, the large-diameter cylinder 1 includes a cylinder body 101 and a piston rod 102. The piston rod 102 is telescopically mounted on the cylinder body 101. A first angle seat 3 and a second angle seat 4 are arranged along the telescopic direction of the piston rod 102. The piston rod 102 is perpendicular to the first vertical seat plate 301 and the second vertical seat plate 401. The first angle seat 3 and the second angle seat 4 are located on both sides of the telescopic direction of the piston rod 102 of the large-diameter cylinder 1, which can prevent the piston of the large-diameter cylinder 1 from impacting the cylinder body 101 during operation, thus preventing the large-diameter cylinder 1 from shaking.

[0036] Furthermore, in this embodiment, the first corner seat 3 is located on the side where the piston rod 102 extends, and the first vertical seat plate 301 is provided with a clearance notch 303. By providing the clearance notch 303, the first vertical seat plate 301 can be set higher, increasing the contact area.

[0037] In this embodiment, the clearance notch 303 is an arc-shaped notch, which matches the structure of the piston rod 102 and avoids scratching personnel or the cylinder surface during installation.

[0038] In addition, the lower mold base 2 is provided with a first mounting hole 202, and the first horizontal base plate 302 and the second horizontal base plate 402 are both provided with second mounting holes 9. The mounting bolt 5 passes through the second mounting hole 9 and is threadedly connected to the first mounting hole 202. The second mounting hole 9 is an oblong hole. The second mounting holes 9 on the first horizontal base plate 302 and the second horizontal base plate 402 are oblong holes, so that the positions of the first corner bracket 3 and the second corner bracket 4 can be adjusted when they are installed on the lower mold base 2.

[0039] Furthermore, the large-diameter cylinder 1 includes a cylinder body 101 and a piston rod 102. The piston rod 102 is telescopically mounted on the cylinder body 101, and the length direction of the second mounting hole 9 is parallel to the telescopic direction of the piston rod 102. That is, the length of the second mounting hole 9 extends along the swaying direction of the large-diameter cylinder 1, which can prevent the connection from breaking due to shearing caused by the swaying direction of the second mounting hole 9 and the large-diameter cylinder 1, and avoid the influence of tangential force.

[0040] Furthermore, the first horizontal seat plate 302 and the first vertical seat plate 301 have a rounded transition, as do the second horizontal seat plate 402 and the second vertical seat plate 401. This results in a larger thickness at the connection between the horizontal and vertical seat plates, improving the structural strength of the corner seat. It also helps prevent scratches to personnel or the cylinder surface during installation.

[0041] In this embodiment, the side of the first horizontal seat plate 302 away from the first vertical seat plate 301 is an arc surface, and the side of the second horizontal seat plate 402 away from the second vertical seat plate 401 is an arc surface, which can prevent scratches to personnel or cylinder surfaces during installation.

[0042] The other structures in this embodiment are the same as in Embodiment 1, and will not be described again here.

[0043] Example 3

[0044] The difference between this embodiment and embodiment two is that, based on embodiment two, this embodiment further explains the mounting structure of the large-diameter cylinder.

[0045] In this embodiment, the large-diameter cylinder mounting structure further includes a locking shaft 6 and a locking nut 7. The large-diameter cylinder 1 includes a cylinder body 101 and a piston rod 102. The piston rod 102 is telescopically mounted on the cylinder body 101. The cylinder body 101 has a first locking hole and a second locking hole, located on both sides of the cylinder body 101 in the telescopic direction of the piston rod 102. The first vertical seat plate 301 has a third locking hole 304, and the second vertical seat plate 401 has a fourth locking hole 403. The locking shaft 6 passes through the first locking hole, the third locking hole 304, the second locking hole, and the fourth locking hole 403. Both ends of the locking shaft 6 are threaded with locking nuts 7. The large-diameter cylinder 1 is connected to the first angle seat 3 and the second angle seat 4 through the locking shaft 6, making the connection and restraint more stable.

[0046] In this embodiment, there are two locking shafts 6, which are arranged in parallel and located on both sides of the large-diameter cylinder 1. The locking shafts 6 are parallel to the piston rod 102.

[0047] In addition, the large-diameter cylinder mounting structure of this embodiment also includes a limiting block 8, which is installed on the lower mold base 2. The limiting block 8, the second corner seat 4, and the large-diameter cylinder 1 are arranged sequentially along the extension and retraction direction of the piston rod 102.

[0048] The lower mold base 2 is provided with a groove 201. The large-diameter cylinder 1 is installed in the groove 201 through the first corner seat 3 and the second corner seat 4. After installation, the first vertical seat plate 301 is in contact with the groove wall of the groove 201. In order to provide space for the installation of the first corner seat 3 and the second corner seat 4, the length of the groove 201 is greater than the sum of the length of the cylinder body 101 of the large-diameter cylinder 1 and the thickness of the first vertical seat plate 301 and the second vertical seat plate 401. Therefore, after the first corner seat 3, the second corner seat 4 and the large-diameter cylinder 1 are installed, a limiting block 8 needs to be placed in the groove 201 to further restrict the cylinder. The limiting block 8 is located between the second vertical seat plate 401 and the groove wall of the groove 201, and the limiting block 8 is in contact with the second vertical seat plate 401.

[0049] Furthermore, in this embodiment, a buffer pad is provided between the first vertical seat plate 301 and / or the first horizontal seat plate 302 and / or the second vertical seat plate 401 and / or the second horizontal seat plate 402 and the large-diameter cylinder 1. The buffer pad serves to eliminate the shaking of the large-diameter cylinder 1. The buffer pad can be a rubber pad or a spring, etc.

[0050] The other structures in this embodiment are the same as in Embodiment 2, and will not be described again here.

[0051] In summary, this embodiment of the invention provides a large-diameter cylinder mounting structure. By setting a first corner seat 3 and a second corner seat 4, which are located on opposite sides of the large-diameter cylinder 1 and are mirror images of each other, and with the first horizontal seat plate 302 of the first corner seat 3 and the second horizontal seat plate 402 of the second corner seat 4 positioned between the first vertical seat plate 301 and the second vertical seat plate 401, the first corner seat 3 and the second corner seat 4 in this embodiment face inwards. This ensures that the space for the large-diameter cylinder 1 to be mounted on the lower mold base 2 is the sum of the length of the cylinder body 101 of the large-diameter cylinder 1 and the thickness of the first vertical seat plate 301 and the second vertical seat plate 401. Therefore, the installation space can be reduced, the mold length can be reduced, and mold costs can be saved. Furthermore, during installation, the first vertical seat plate 301 and the second vertical seat plate 401 contact the lower mold base 2, resulting in a large contact area, thereby increasing the force-bearing area and more stably restraining the large-diameter cylinder 1. Furthermore, in this embodiment, the large-diameter cylinder 1 is located above the first horizontal seat plate 302 and the second horizontal seat plate 402. According to the torque principle, this embodiment improves the position of the fulcrum, making the lever arm length smaller. Under the same force, the torque on the cylinder is reduced, which can effectively solve the problem of the large-diameter cylinder 1 shaking.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
