Background technology
Marine anchor chain and mooring anchor chain are a kind of important mooring components that is widely used in boats and ships stop and offshore oil mooring engineering (oil drilling platform, single point mooring unit etc.), and the quality of its quality is related to the safety of boats and ships stop and ocean mooring engineering.The manufacturing process of cable link is: the shaping-flash of light of bar heating-horizontal curvature is welded-is gone and welds burr-be pressed into crosspiece.In the operation that horizontal curvature is shaped, the bar after will heat earlier leans against on the arc envelope face of center push rod, utilizes the mobile of center push rod after closed and locked then, makes the bar that is clipped in the heating in two bending rollers curve needed annular.Bar after the heating is wanted successively through twice horizontal curvature, in second time horizontal curvature process, is inserted in Manufactured a last chain link, curves the ring body of sealing then, then changes down the road welding sequence that glistens over to, and such articulating one encircles makes Anchor chain link.The quality of horizontal curvature forming quality directly has influence on the carrying out of road, back flash of light welding sequence, attractive in appearance in order to guarantee the product annular, the regulation that meets relevant specification, and can from mould, take out the chain link of bending forming, center push rod must be made and can open up and down, the structure of closure, in chain link horizontal curvature forming process, upper and lower center push rod is locked in closure state all the time, and this just needs a kind of closure and locking device of special center push rod to realize this function.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, be easy to install and remove and the closure and the locking device of rods of anchor chain ring bending machine center push rod easy to maintenance.
The present invention is achieved by the following technical programs:
A kind of closure of ring bending machine center push rod and locking device comprise close mechanism, retaining mechanism and locking pedestal, and described retaining mechanism is arranged in the close mechanism; Described close mechanism comprise crank arm, upper and lower center push rod, this close mechanism is arranged in the described locking pedestal; Described lower end of cranking arm is hinged by first bearing pin and described locking pedestal, and the other end is fixedlyed connected with last center push rod; Described center push rod down is fixed on the front end of locking pedestal, and described locking pedestal is fixedly installed on the top of sliding beam; Described retaining mechanism comprises upper lock body, down lock body and oil cylinder, and this retaining mechanism is arranged in the described close mechanism; The horizontal bearing pin that described oil cylinder middle part is provided with is hinged with the locking pedestal, and described oil cylinder piston club head is hinged by the middle part of the 3rd bearing pin and upper lock body; In described upper lock body was arranged on and cranks arm, its upper end was hinged by second bearing pin and described upside of cranking arm; The bottom of described down lock body is fixed on the upside of sliding beam; During locking state, described upper and lower lock body fastens upper and lower center push rod closure.
Purpose of the present invention can also further realize by following technical measures.
The closure of aforesaid ring bending machine center push rod and locking device, wherein said cranking arm comprises long-armed and galianconism, and this is cranked arm and forms body structure by two blocks of side plates and upper push-rod seat, contiguous block, and the upper and lower sides of described body structure is unimpeded.
The closure of aforesaid ring bending machine center push rod and locking device, wherein said upper lock body, down lock body are the hook structure, described hook structure hook end is respectively equipped with voussoir, described voussoir is fixedlyed connected with the hook end of upper and lower lock body respectively by securing member, during locking state, the inclined-plane wedging of described voussoir, the angle on described voussoir inclined-plane are 12 °～15 °.
The closure of aforesaid ring bending machine center push rod and locking device, wherein said locking pedestal comprises the vertical side plate of two pedestals, the downside of the vertical side plate of described two pedestals is fixedlyed connected with the upside of sliding beam.
The closure of aforesaid ring bending machine center push rod and locking device, the shape of wherein said upper and lower center push rod, big or small identical, the excircle at the two closed place is provided with the concave arc enveloping surface, the radius of curvature of described concave arc enveloping surface cross section equates that with the radius of system chain bar the circle diameter of its closing face is 1.68～1.7 times of cable link ring body nominal diameter.
Retaining mechanism of the present invention is arranged in the close mechanism, and compact conformation is convenient to installation, maintenance and maintenance.The present invention adopts many bars linkwork dexterously, has only just realized closure and two functions of locking of center push rod with an oil cylinder.After the upper and lower center push rod closure, because the radius of the radius of curvature of the concaved circular cambered surface at its closed place and bar mates, and the circle diameter of its closing face is slightly larger than the inner width of cable link ring body, guarantees to bend the specification requirement annular up to specification that.When oil cylinder loads, promote upper lock body, make the voussoir inclined-plane extruding of upper lock body and down lock body, utilize 12 °～15 ° the little angle of wedge, good locking effect after the center push rod closure about the normal force of compressive plane can reach, simultaneously, guarantee that center push rod does not misplace, thereby further guaranteed the presentation quality of cable link.
Advantage of the present invention and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
