Description
Technical field
The utility model relates to the securing device of the middle crosspiece of a kind of mooring anchor chain chain link, especially a kind of by laterally pushing crosspiece, crosspiece two ends after making to extend deeper fall in the chain link ring body, thereby prevent the device that crosspiece is loosening, belong to mooring anchor chain manufacturing equipment technical field.
Background technology
The mooring anchor chain is the vitals that is related to the moorings in ocean such as Offshore Engineering device, oil drilling platform and single point mooring unit, and the quality of its quality is related to the safety of ocean mooring engineering.The mooring anchor chain includes grade mooring anchor chain and, without two kinds, shelves mooring anchor chain, is divided into R3, R3S, R4, R4S and R5 totally 5 ranks, wherein has grade mooring anchor chain to compress into respectively the crosspiece of corresponding ring body medial surface in horizontal termination, two ends at the chain link ring body middle part of sealing.According to classification society rule's requirement, R3, other mooring anchor chain chain link of R3S level allow crosspiece one end to be welded on corresponding ring body inboard, more than the R4 level, have grade crosspiece of mooring anchor chain not allow welding.When the mooring anchor chain is manufactured, because mooring anchor chain raw MAT'L hardness is high, when adding the contrachain ring ring body and being pressed into crosspiece, its temperature descends rapidly, and the resistance of deformation increase of chain link ring body, cause crosspiece to be pressed into insufficient, and heat treatment is by often occurring that crosspiece becomes flexible phenomenon.Such mooring anchor chain easily produces the defects such as crosspiece comes off, inclination in actual use due to factors such as marine corrosions, thereby affect the comprehensive mechanical performance of whole chain, also had a strong impact on the use safety of Offshore Engineering device, oil drilling platform and single point mooring unit.For above-mentioned situation, increase at present support shelves technique before final check after tension test for chain cable, in support shelves cutter extruding for the crosspiece both lateral sides, make the crosspiece both lateral sides V-arrangement impression of certain depth occur, after crosspiece produces plastic deformation, extend at its two ends, thereby the concaved circular cambered surface at its two ends is deeper fallen in the chain link ring body, reach the problem that open-set mark occurs that solves after chain link heat treatment.
Existing anchor chain support latch device comprises tool rest and a support shelves cutter, and a support shelves cutter only has a blade, and blade adjacent surface angle only has 60 °, and blade easily bursts apart, and service life is shorter, and the crosspiece plastic deformation produced that is squeezed is little, after heat treatment, still has the open-set mark phenomenon to occur.Because support shelves cutter bottom is less with the area of contact of tool rest, the compression effort of the contact surface of tool rest is larger, and after the extruding crosspiece, support shelves cutter bottom easily is stuck in tool rest, and tool changing is extremely inconvenient, and often tool changing affects production efficiency, increases productive costs.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, cost is low, cutter easy accessibility, support shelves are effective that a grade mooring anchor chain support latch device is arranged.
The utility model is achieved by the following technical programs:
A kind of have grade mooring anchor chain to support a latch device, comprises two tool rests that are oppositely arranged, a support shelves cutter, top board and side guide, and described tool rest outside forming V-shape sinks, and fixed base plate is extended in the tool rest inboard; The fixed base plate of a tool rest is fixedly connected with support shelves hydropress frame, and the fixed base plate of another tool rest is fixedly connected with Cylinder Plunger by template; Described support shelves cutter is four prism type, and four sides of described four prism type are intersected forming V-shape in twos, the top formation blade of V-arrangement, the V-arrangement sinking tabling of support shelves cutter one side and tool rest; Two top boards are symmetrical arranged, top board one side is fixed on tool rest, and the top board opposite side is pushed down support shelves cutter, and the blade of support shelves cutter opposite side stretches out two spaces between top board, the vertical both ends of the surface of support shelves cutter are resisted against respectively on side guide, and described side guide is fixed on the tool rest two ends; During the support shelves, the blade of support shelves cutter is compressed into respectively at crosspiece two middle side parts.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid have grade mooring anchor chain to support a latch device, and wherein said support shelves cutter cross-sectional plane is four jiaos of squares that change into fillet.
Aforesaid have grade mooring anchor chain to support a latch device, wherein said top board lopsidedness, and the side of inclination is pressed on support shelves cutter side.
The utility model is simple in structure, easy accessibility, and support shelves cutter has four blades, after blade wearing and tearing, only it need be rotated to 90 °, can use another blade support shelves, and the support shelves cutter life-span improves more than four times.A support shelves cutter cross-sectional plane is four jiaos of squares that change into fillet, processes very conveniently, greatly reduces the cutter cost of manufacture, has improved work efficiency.In addition, 90 ° of angles of every blade adjacent surface, make blade be difficult for bursting apart.The area of contact of support shelves cutter and tool rest increases, and has reduced both contact stress, and support shelves cutter bottom is difficult for being stuck in tool rest.The crosspiece both lateral sides larger plastic deformation of rear generation that is squeezed, make its two ends be connected firmly with the corresponding inboard of chain link ring body.
Advantage and disadvantage of the present utility model, will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment, only provide as an example with reference to accompanying drawing.
