Description

The anchor chain crosspiece becomes swage die

Technical field

The utility model relates to a kind of forging die of anchor chain crosspiece, and especially a kind of multi-direction anchor chain crosspiece that the heating blank is carried out no-draft forging becomes swage die, belongs to the forge die technical field.

Background technology

Anchor chain is the important outfititem that is related to boats and ships and ocean engineering safety; The chain ring body of modern anchor chain generally adopts twice bending of the round steel bar process special equipment after the heating and the chain ring body that flash welding is connected into sealing; The middle part of chain ring body is provided with crosspiece; Improving its intensity, thereby increase the tensile load that anchor chain can bear.As depicted in figs. 1 and 2; The shape of anchor chain crosspiece 10 is the little dumb-bell shape in big centre, two; Its two ends are arc surface 100, and this arc surface 100 is vertical with the vertical symmetrical centre section of anchor chain crosspiece, and the arc surface 100 at anchor chain crosspiece 10 two ends is pressed into the laterally inboard overall structure that forms of chain ring body; Anchor chain crosspiece 10 is loosening even come off in the time of can preventing to use effectively, influences the safety of boats and ships and ocean engineering.

Existing anchor chain crosspiece adopts forcing press or forging hammer open die forging, impressing forging to be shaped; Can be full of the arc surface place at the vertical two ends of impression in order to ensure blank; The horizontal parting face of anchor chain crosspiece is provided with the overlap of sealing; Also need after the die forging of anchor chain crosspiece with forcing press and the overlap of cutting overlap punch die excision anchor chain crosspiece, the die forging process of anchor chain crosspiece needs two forcing presses, two molds and two procedures just can process, and manufacturing cost is higher; Owing to there is overlap, make the stock utilization of anchor chain crosspiece die forging about 85%, material consumption is bigger, and in addition, because impression and the overlap of sealing are close to the counterdie upside, it is difficult to cause anchor chain crosspiece forging part to take out.

Summary of the invention

The purpose of the utility model provides a kind of anchor chain crosspiece simple in structure, that manufacturing cost is lower and becomes swage die, improves the operating efficiency of anchor chain crosspiece die-forging forming, reduces manufacturing cost.

The utility model is achieved through following technical scheme:

A kind of anchor chain crosspiece becomes swage die; Comprise last forging die and anvil tool and lay respectively at forging die and the side forging die of the evagination at anvil tool two ends with impression; Said forging die and the symmetrical up and down mould that divides of anvil tool, said forging die impression two ends and the anvil tool impression open at both ends of going up of going up; Last forging die comprises upper mold core and upper bolster, and anvil tool comprises lower mold core and die shoe, and the side forging die comprises side form core and side form seat, and upper mold core, lower mold core and side form core are fixedly connected with corresponding die holder respectively; Upper bolster is fixedly connected with the vertical termination of suppressing the oil cylinder piston bar of anchor chain crosspiece hydraulic forming machine; Die shoe is fixed on the lower table plate of anchor chain crosspiece hydraulic forming machine, and a pair of side form seat is fixedly connected with the termination of anchor chain crosspiece hydraulic forming machine level compacting oil cylinder piston bar respectively; When the side form core at upper mold core, lower mold core and two ends is closed, between upper mold core and the lower mold core, all leave the space between upper mold core and lower mold core two ends and the side form core.

The purpose of the utility model can also further realize through following technical measures.

Aforesaid anchor chain crosspiece becomes swage die; The junction of wherein said upper bolster, die shoe and side form seat and corresponding core rod is equipped with deep gouge; The link of said upper mold core, lower mold core and side form core and corresponding die holder is coattail end, and said coattail end places the deep gouge of corresponding die holder respectively, and the gib head pressing plate is fixed on the corresponding die holder through several securing members; Gib head pressing plate one end is resisted against on the coattail end of corresponding core rod, and the gib head pressing plate other end is resisted against on the corresponding die holder.

Aforesaid anchor chain crosspiece becomes swage die, and wherein said upper mold core two ends and lower mold core two ends are respectively equipped with fillet surface, and the angle of said fillet surface and horizontal plane is 55 °～65 °.

Aforesaid anchor chain crosspiece becomes swage die, and wherein said die shoe bottom is positioned on the lower table plate of anchor chain crosspiece hydraulic forming machine through positioning key.

The utility model is simple in structure, easily manufactured; Change the existing anchor chain crosspiece forging die of mould that vertically divides up and down into vertical up and down, that left and right horizontal is divided mould combined type forging die; Be in strong three-dimensional compressive stress state in the anchor chain crosspiece forming process, the plasticity of blank is high, good fluidity.During the moulding of anchor chain crosspiece, because between the upper and lower core rod, all leave the space between upper mold core and lower mold core two ends and the side form core, blank is filled to each gap of flow resistance minimum naturally in flow process, make that the moulding of anchor chain crosspiece is full, attractive in appearance.Between the upper and lower core rod, between upper and lower core rod two ends and the side form core not between generating plane and the face the hard of impact contact, the volume of core rod is less, service life is longer, has reduced manufacturing cost.Adopt the utility model forging and pressing anchor chain crosspiece; Only need an equipment, can accomplish once cover forging die and one procedure; The anchor chain crosspiece non-trimming that forges and presses out, blank does not have other losses except that scaling loss, and stock utilization is much higher than the anchor chain crosspiece of prior art open die forging, impressing forging.Because impression do not seal and the forging part non-trimming, from impression, take out the anchor chain crosspiece and take very conveniently, improved operating efficiency.

Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
