Abstract
The utility model relates to a cast-steel harvester U-shaped universal joint provided with a tie bar, which uses cast-steel sodium silicate CO2 hardening sand to model. The tie bar is arranged on the U-shaped right side of the harvester universal joint and is connected with the upper part of the left side. The tie bar is condensed before the harvester U-shaped universal joint is condensed, so that the tie bar has a support force, cannot be broken by stress and plays a role for preventing a casting from deforming. The designed thickness of the tie bar is 50 percent of the thickness of the casting, i, e,. a/b=c/d=50 percent. The smelted ZG310-570 molten steel is crushed into a straight runner and enters into an inner runner and is then full in a cavity of the harvester universal joint provided with the tie bar. According to the cast-steel harvester U-shaped universal joint provided with the tie bar, the problem that the distance size between the U-shaped right side and the left side is unqualified due to casting deformation is solved, the production processes are reduced, and the production cost is reduced.
Description
Technical field
The utility model relates to the casting cast steel product, and especially cast steel is provided with the harvester U-shaped universal joint of lacing wire.
Background technology
At present casting cast steel harvester U-shaped universal joint is overproof because of the casting distortion apart from size between the U-shaped both sides, and it is qualified that the shaping through complicacy just can reach size, causes trouble and increase cost to production.
Summary of the invention
The harvester U-shaped universal joint that the utility model provides a kind of cast steel to be provided with lacing wire, lacing wire design for preventing to cast distortion, has overcome between universal joint U-shaped both sides apart from because of being out of shape overproof problem.
The utility model solves the technical scheme that its technical problem adopted: the harvester U-shaped universal joint, U-shaped right side, lacing wire, U-shaped left side, the last sand mold that are provided with lacing wire by drag box, cast steel type waterglass CO2 hardened sand, ingate, sprue, case outside fix, axis hole cast steel type waterglass CO2 hardened sand core, cast steel are formed.With the moulding of cast steel type waterglass CO2 hardened sand; Be provided with harvester U-shaped universal joint female die that cast steel is provided with lacing wire, ingate at following sand mold, axis hole cast steel type waterglass CO2 hardened sand core is positioned on the core print seat, lacing wire is located at U-shaped right side is connected with left upper portion; Be provided with harvester universal joint upper mold section, the sprue that cast steel is provided with lacing wire at last sand mold; Last sand mold and following sand mold are with case outside fix finger setting mould assembly; Melted ZG310-570 molten steel is full of the harvester U-shaped universal joint die cavity that is provided with lacing wire after pouring the sprue ingate.
Lacing wire thickness accounts for the α/b=c/d=10/20=20/40=50% of U-shaped left side and right upper portion thickness.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the structure chart that cast steel is provided with the 4y B-2 type wheat harvester U-shaped universal joint of lacing wire.
Fig. 1 is the B-B profile of Fig. 2.
Fig. 2 is the A-A profile of Fig. 1.
Among the figure 1, sand mold down, 2, cast steel type waterglass CO2 hardened sand, 3, ingate; 4 sprues, 5, the case outside fix, 6, axis hole cast steel type waterglass CO2 hardened sand core; 7, cast steel is provided with the harvester U-shaped universal joint of lacing wire, and 8, the U-shaped right side, 9, lacing wire; 10, U-shaped left side, 11, go up sand mold.
The specific embodiment
In accompanying drawing 1,2; Cast steel type waterglass CO2 hardened sand 2 moulding with ZGS96-42Q-30 sand; Be provided with female die, the ingate 3 that cast steel is provided with the harvester U-shaped universal joint 7 of lacing wire 9 on the sand mold 1 down; The cast steel type waterglass CO2 hardened sand core 6 of axis hole ZG96-42Q-30 sand is positioned on the corresponding core print seat; The α of lacing wire 9=10 millimeter c=20 millimeter is located at the top b=20 millimeter d=40 millimeter that U-joint 7 connects left side 10 and right side 8, makes lacing wire 9 first condensation before cast steel is provided with harvester U-shaped universal joint 7 condensations of lacing wire have support force and is not broken the effect that prevents to cast distortion of playing by stress again; Be provided with harvester U-shaped universal joint 7 upper mold sections, the sprue 4 that cast steel is provided with lacing wire 9 at last sand mold 11; Last sand mold 11 is located mould assemblys with following sand mold 1 with case outside fix pin 5; Melted ZG310-570 molten steel pours and is full of harvester universal joint 7 die cavities that cast steel is provided with lacing wire after sprue 4 gets into ingate 3 again.In order to prevent distortion, after heat treatment, to remove lacing wire 9 just cast steel is provided with the harvester U-shaped universal joint 7 of lacing wire 9.
Lacing wire thickness is the α/b=c/d=10/20=20/40=50% that accounts for U-joint top thickness.
