[0002] The hinge beam is an important component of the six-sided top press, mainly used to bear the axial thrust of the working cylinder and support the working cylinder. The hinge beam connection method used in six-sided top presses below model 560 is a set fit of pins and pin sleeves; this type of hinge beam connection method is troublesome to disassemble and install, and has low maintenance efficiency; while the hinge beam connection method used in six-sided top presses above model 650 is a set fit of solid cylindrical pins and pin holes. The solid cylindrical pin itself is heavy, so lifting equipment is required for installation or removal; however, the surface of the solid cylindrical pin is smooth, and conventional lifting equipment is difficult to form a stable lifting point on the solid cylindrical pin; therefore, there is a risk of the solid cylindrical pin falling during the lifting process.

[0024] Compared with the prior art, the hollow structure 11 of the present invention can not only reduce the weight of the pin shaft 1, but also provide a stable lifting point for the lifting equipment, thereby reducing the difficulty of lifting the pin shaft 1 and ensuring the efficiency of disassembly and installation.

[0025] There are two end covers 2, which are symmetrically arranged at both ends of the pin shaft 1; each end cover 2 is connected to the end of the pin shaft 1; both ends of the pin shaft 1 can be axially limited by the end cover 2 to ensure the installation stability of the pin shaft 1.

[0026] The end cap 2 is provided with at least two through holes 21; the connecting screw 3 passes through the through holes 21 and connects with the pin 1; thus, the connection strength between the end cap 2 and the pin 1 is improved. In this embodiment, there are three through holes 21 on the end cap 2.

[0027] The through holes 21 are distributed around the circumference of the pin 1 , so that the end cover 2 and the end of the pin 1 form a stable connection.

[0028] The hollow structure 11 is a cylindrical cavity coaxially arranged with the pin shaft 1, so that lifting tools such as wire ropes and slings can pass through the cylindrical cavity for lifting; the wear of the wire ropes and slings can be reduced.

[0029] The inner diameter of the hollow structure 11 is 30% of the outer diameter of the pin 1, so that the pin 1 retains sufficient structural strength while reducing its own weight.

[0030] The edges of the hollow structure 11 are provided with rounded corners 12 to reduce the wear of slings such as wire ropes and slings.

[0031] The end cover 2 is coaxially arranged with the pin shaft 1 to evenly shield the pin shaft 1 and ensure the stability of the end cover 2 in limiting the pin shaft 1.

[0032] The end cover 2 is disc-shaped, which is conducive to turning processing and reduces production costs.

[0033] The end face of the pin shaft 1 is provided with a threaded hole 13 which is threadably matched with the connecting screw 3; the threaded hole 13 can also be used to connect a lifting ring for lifting equipment.

[0034] The installation process of this embodiment includes the following steps:

[0035] ① Connect the side hinge beam 01 to the bottom hinge beam 01

[0036] Use a wire rope or a sling to pass through the hollow structure 11; use a lifting device to lift the wire rope or sling to lift the pin shaft 1 and lift the pin shaft 1 to a certain height; the height is the same as the pin hole 011 connected to the side hinge beam 01 and the bottom hinge beam 01; remove one end of the wire rope or sling from the hook, pass it through all the corresponding pin holes 011 in turn, and then hang it on the hook again; lift the pin shaft 1 again and adjust the position of the lifting device; the pin shaft 1 slowly slides toward the pin hole 011; the installer uses the sliding of the pin shaft 1 to insert a part of the pin shaft 1 into the pin hole 011; when the pin shaft 1 is inserted into the pin hole 011 to a sufficient depth, slowly lower the hook to relax the wire rope or sling; the installer pushes the pin shaft 1 so that the pin shaft 1 is completely inserted into the pin hole 011; use the connecting screw 3 to install the end cover 2 on the end of the pin shaft 1 to fix the side hinge beam 01 and the bottom hinge beam 01;

[0037] ② Connect the hinge beams 01 on the side

[0038] Lift the pin 1 upright; use the connecting screw 3 to connect the end cover 2 to the upper end of the pin 1; at least one through hole 21 on the end cover 2 and at least one threaded hole 13 on the upper end of the pin 1 are not installed with the connecting screw 3; use a lifting ring to pass through the remaining through hole 21 and threadedly connect it to the threaded hole 13; use a lifting device to lift the lifting ring, and then lift the pin 1 vertically; align the lower end of the lifted pin 1 with the pin hole 011 used for connecting the side hinge beam 01; slowly lower the hook so that the pin 1 is completely inserted into the corresponding pin hole 011 until the end cover 2 is connected to the side hinge beam 01; remove the lifting ring; use the connecting screw 3 to connect the remaining through hole 21 and threaded hole 13; use the connecting screw 3 to install the end cover 2 to the lower end of the pin 1 to achieve fixation between the hinge beams 01 on the adjacent sides;

[0039] ③ Connect the side hinge beam 01 with the top hinge beam 01

[0040] The fixing process of the side hinge beam 01 and the top hinge beam 01 is basically the same as the fixing process of the side hinge beam 01 and the bottom hinge beam 01 in step ①, and will not be repeated in this article.

[0041] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, and the similarities are not repeated here. The difference is that the top edge of the end cover 2 has a rounded corner 22 to avoid cutting the installation workers.

[0042] The bottom of the end cover 2 abuts against the hinge beam to prevent the pin shaft 1 from axially moving, thereby increasing the connection stability of the adjacent hinge beams 01.
