Description
Technical Field
[0001] This utility model relates to the field of multi-wire cutting technology, specifically a lifting device for hoisting multi-wire cut workpieces. Background Technology
[0002] Multi-wire cutting machines use the high-speed reciprocating motion of metal wires (cutting wires) to bring abrasive into the processing area of the material to be cut for grinding, and simultaneously cut the workpiece into hundreds or thousands of thin slices. They have the advantages of high working efficiency and low material loss.
[0003] Before a multi-wire cutting machine can perform cutting operations, it must first complete the material bonding process, that is, attach the workpiece to the material plate. With the widespread application of multi-wire cutting technology, the size of the workpiece being cut is trending towards larger dimensions, leading to the development of oscillating multi-wire cutting machines, as shown in the attached image. Figure 1 The large workpiece 1 shown is cut using a multi-wire cutting machine with a swing-type worktable. During the cutting operation, the workpiece 1 is suspended on the swing worktable by a material plate 2, so its bonding surface is located on the upper end face of the workpiece 1. The material plate 2 is provided with guide rails and positioning holes 2-2 that cooperate with the swing worktable. The guide rails are T-slots 2-1. In addition, since the workpiece 1 is heavy, it is generally transported from the bonding station to the multi-wire cutting loading station by a crane. Therefore, a special lifting tool needs to be designed to assist in the lifting operation of the workpiece 1. Utility Model Content
[0004] This utility model provides a lifting device for hoisting multi-wire cut workpieces. It aims to innovate the connection and positioning structure between the lifting device and the workpiece by utilizing the structural features of the material plate, so as to ensure the safety of the workpiece during hoisting and improve work efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A lifting device for hoisting multi-wire cut workpieces includes a lifting rail, a lifting ring, a lifting rail connecting plate, a positioning and fixing block, and a positioning pin.
[0007] The lifting rail is an inverted T-shaped cross-section profile, and there are at least two sets of lifting rails. Their specifications and dimensions match the T-shaped groove of the material plate on the workpiece. The lifting rails are inserted into the T-shaped groove of the material plate, and two adjacent sets of lifting rails are fixed together by a detachable lifting rail connecting plate.
[0008] The lifting rings are installed on the lifting rails, and there are no fewer than four sets of them, arranged in a symmetrical manner front-to-back and left-to-right.
[0009] The positioning and fixing block is installed on the side wall of the hanging rail, and a positioning pin is fitted on the positioning and fixing block;
[0010] The lower end of the positioning pin passes through the positioning hole in the material plate.
[0011] The aforementioned lifting device for hoisting multi-wire cut workpieces has a lifting rail connecting plate that is fixedly assembled to the vertical wall of the T-section profile lifting rail by bolts.
[0012] The aforementioned lifting device for hoisting multi-wire cut workpieces has guide surfaces on the front and rear end faces of the lifting rail. These guide surfaces are wedge-shaped and symmetrically arranged on the left and right sides of the lifting rail.
[0013] The aforementioned lifting device for hoisting multi-wire cut workpieces has at least two sets of lifting rail connecting plates, arranged symmetrically front and back, located at the assembly position of the lifting ring and the lifting rail.
[0014] The aforementioned lifting device for hoisting multi-wire cut workpieces uses a resilient positioning pin as the positioning pin.
[0015] This invention provides a lifting device for hoisting workpieces cut by multi-wire cutting. It achieves lateral positioning by inserting a lifting rail into the T-slot of the top material plate of the workpiece; lateral positioning by inserting a positioning pin, which cooperates with a positioning block, into the positioning hole of the material plate; and convex positioning by using a lifting ring in conjunction with a crane hoisting rope to lift the workpiece from the material loading station to the loading station of the multi-wire cutting machine. In this invention, adjacent sets of lifting rails are fixed together by a detachable lifting rail connecting plate. When assembling with the T-slot on the material plate, the lifting rails can be assembled one by one with the corresponding T-slots on the material plate. Then, a lifting rail connecting plate of appropriate size is selected, and the lifting rails and the connecting plate are fixed together with bolts. This allows the lifting device to be used with material plates of different widths, improving its versatility. This invention also provides guide surfaces on the front and rear ends of the lifting rails, further facilitating the assembly of the lifting rails with the T-slots of the material plate. In summary, this utility model utilizes the structural features of the material plate to innovatively design the connection and positioning structure between the lifting device and the material plate, thereby achieving the goals of ensuring safety and improving work efficiency during workpiece lifting.

[0034] See Figure 2 , Figure 4 , Figure 5 In a preferred embodiment of the lifting device for lifting multi-wire cut workpieces described in this utility model, the lifting rail connecting plate 3-3 is fixedly assembled to the vertical wall of the T-section profile lifting rail 3-1 by bolts 3-6. In another embodiment, the lifting rail connecting plate 3-3 and the T-section profile lifting rail 3-1 can also be fixedly assembled together by a detachable structure such as snap-fit or plug-in connection. There are at least two sets of lifting rail connecting plates 3-3, arranged symmetrically front and back, located at the assembly position of the lifting ring 3-2 and the lifting rail 3-1.
[0035] See Figures 1 to 8 When using this utility model in conjunction with an overhead crane to lift a multi-wire cut workpiece 1, the lifting rail 3-1 can first be inserted into the T-slot 2-1 of the top material plate 2 of the workpiece 1 to achieve left-right positioning of the lifting device. Then, the positioning pin 3-5, which cooperates with the positioning fixing block 3-4, is inserted into the positioning hole 2-2 of the material plate 2 to achieve front-back positioning of the lifting rail. Select a lifting rail connecting plate of appropriate specifications and size, and fix two adjacent sets of lifting rails 3-1 and lifting rail connecting plates 3-3 with bolts 3-6.
