Description

Technical Field

[0001] The invention relates to the technical field of shearing machines, in particular to an assembly hanger for a tool holder on a rolling shear and a use method thereof. Background Art

[0002] The rolling shear is a key equipment in the plate production line, mainly used to shear the head, tail and edge of the steel plate. The upper blade holder of the rolling shear needs to be removed and the slide plate inside the upper blade holder needs to be replaced every two years. Figure 2 As shown: There are two eccentric shafts on the shear body reducer of the shearing machine. When the machine is stopped, the equipment must be in the safe position with the lowest center of gravity. When the two eccentric shafts are in the lowest position, start to remove the upper tool holder. In normal use, the upper tool holder is installed on the eccentric shaft of the shear body through the eccentric shell.

[0003] The difficulty in installing the upper tool holder is that the eccentric wheel housing can rotate around the pin and has a small clearance with the eccentric shaft. The clearance between the eccentric shaft and the inner hole of the eccentric wheel housing is 0.3mm-0.5mm. The clearance between the inner hole of the eccentric wheel housing and the eccentric shaft is small and the eccentric housing can rotate around the pin. Therefore, it is not easy to align during the assembly process. It is often the case that one is installed and the other is not aligned. Sometimes, it may take ten hours to assemble and it is still not assembled properly. One may even get stuck and damage the eccentric shaft surface. Summary of the invention

[0028] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below according to specific implementation modes and in combination with the accompanying drawings.

[0029] Figure 1 A schematic diagram of the structure of the assembly sling of the upper tool holder of the rolling shear provided in an embodiment of the present application when in use. The assembly sling comprises a hook 1 and a first fall chain 2, a second fall chain 3, a third fall chain 4, a fourth fall chain 5, a first anti-fall rope 6 and a second anti-fall rope 7 connected to the hook 1.

[0030] Specifically, the hook 1 is fixedly mounted on the crane, and is driven by the crane to move up and down and to move left and right.

[0031] The upper ends of the first fall chain 2, the second fall chain 3, the third fall chain 4 and the fourth fall chain 5 are all suspended on the hook 1, so that when the crane drives the hook 1 to move, the first fall chain 2, the second fall chain 3, the third fall chain 4 and the fourth fall chain 5 can be driven to move synchronously.

[0032] The upper ends of the first anti-fall rope 6 and the second anti-fall rope 7 are fixedly connected to the hook 1. The first anti-fall rope 6 and the second anti-fall rope 7 are equal in length. The first anti-fall rope 6 and the second anti-fall rope 7 mainly serve as insurance. In this embodiment, the first anti-fall rope 6 and the second anti-fall rope 7 are both steel wire ropes, and the bearing capacity of each steel wire rope is greater than half of the weight of the upper knife holder 8.

[0033] This embodiment also provides a method for using an assembly hanger for a rolling shear upper tool holder, the method comprising steps S101 to S107, and the specific steps are described as follows:

[0034] Step S101: The lower ends of the first fall chain 2 and the second fall chain 3 are respectively hung on the two eccentric wheel shells 9 of the upper tool holder 8.

[0035] Specifically, the first fall chain 2 and the second fall chain 3 are mainly used to adjust the angles of the two eccentric wheel shells 9. In this embodiment, a fall chain with a bearing capacity of about 2t can be used.

[0036] Step S102: Hang the lower ends of the third fall chain 4 and the fourth fall chain 5 on the two hanging points 11 of the upper tool holder 8 respectively.

[0037] Specifically, the third fall chain 4 and the fourth fall chain 5 are mainly used to hoist the upper tool holder 8 as a whole.

[0038] Step S103: The first anti-fall rope 6 and the second anti-fall rope 7 are respectively fixedly connected to the two hanging points 11 of the upper tool holder 8. It should be noted that the first anti-fall rope 6 and the second anti-fall rope 7 are mainly used to prevent the upper tool holder 8 from falling and being damaged when the third fall chain 4 and the fourth fall chain 5 are accidentally broken. The first anti-fall rope 6 and the second anti-fall rope 7 are not subjected to force under normal circumstances.

[0039] Step S104: the crane drives the hook 1 to rise, lifts the upper tool holder 8, and adjusts the lengths of the third fall chain 4 and the fourth fall chain 5 to make the upper tool holder 8 in a horizontal state.

[0040] Step S104: The upper tool holder 8 is moved by the crane so that the two eccentric wheel shells 9 on the upper tool holder 8 and the two eccentric shafts 13 on the shear body 12 are at the same height and aligned in the horizontal direction, and the horizontal spacing is 5-10 mm.

[0041] Step S105: respectively adjusting the lengths of the first fall chain 2 and the second fall chain 3 so that the angles of the two eccentric wheel shells 9 are equal to the angles of the two eccentric shafts 13 .

[0042] Step S106: The upper tool holder 8 is moved by the crane, and the position of the upper tool holder 8 is finely adjusted so that the two eccentric wheel shells 9 and the two eccentric shafts 13 are completely aligned in the horizontal direction.

[0043] Step S107: The upper tool holder 8 is driven by the crane to move horizontally toward the shear body 12, so that the two eccentric wheel shells 9 are respectively installed on the two eccentric shafts 13 and installed in place.

[0044] After adopting the technical solution of the present application, the assembly process that originally required 8 hours or even longer now only takes about 1 hour, and will not damage the crankshaft surface, saving time and effort.

[0045] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
