Abstract
The utility model relates to the technical field of engineering machinery, in particular to a feed head used for casting gear rings. The feed head used for casting gear rings is connected to the upper part of a sand casting die used for casting gear rings, and is characterized by comprising a bottom part, a side wall and a top wall, wherein the feed head adopts a waist cylindrical structure, the side length of the cross section of the bottom part of the feed head is 230-235 mm, and the hem width of the cross section of the bottom part of the feed head is 120-125 mm, the height of the side wall of the feed head is 295-305 mm, and the top wall and the bottom part both of the feed head are the same in structure and size. The feed head used for casting gear rings, provided by the utility model, adopts a unique structure, large area of loosening can be avoided due to the gear rings cast by the feed head, and the product yield rate of gear ring blanks is improved.
Description
Technical field
The utility model relates to technical field of engineering machinery, is specifically related to a kind of for casting the rising head of gear ring.
Background technology
Gear ring is large-scale mixing plant, mining equiment, the drive disk assembly of key in the engineering mechanical devices such as electric machinery, the quality of gear ring directly affects the stationarity of equipment transmission, affect the service life of equipment, therefore require gear ring to there is intensity high, toughness is strong, the requirement that fatigue resistance is good, existing gear ring is normally made gear ring blank by casting technique, by fine finishining, complete again the manufacture of workpiece, the casting method that application publication number is the disclosed a kind of super-huge half-ring gear of CN102205397A as awarded, it is characterized in that: adopt the whole circle open riser of outer rim, additional insulating riser sleeve, inner circle subsidy, cylindrical iron chill shock chilling, inner edge disperses circular insulation blind riser, and corresponding bottom iron chill shock chilling, obtains half-ring gear blank.In casting gear ring process, rising head is for compensate for shrinkage, therefore the design of rising head has important impact to the quality of gear ring blank, if riser height is too low, can affect feeding effect, and Tai Gao may cause that again ingate is overheated, rising head diameter is excessive, and foundry goods easily produces shrinkage porosite by rising head place.
Utility model content
Existing for casting the deficiency of the rising head of gear ring in order to overcome, the utility model provides a kind of and has been conducive to most for casting the rising head of gear ring, described rising head is connected in for casting the sand casting mould top of guide wheel support, it is characterized in that: described rising head comprises bottom, sidewall and roof, this rising head is up big and down small cone structure, its bottom is square with the cross section of roof, the length of side in this rising head bottom transverse cross section is 140-145mm, the large 28-32mm of the length of side of the side ratio bottom section of roof cross section, the wall thickness of rising head sidewall is 13-18mm, and this sidewall height is 200-210mm.
Further, the wall thickness of described rising head sidewall is 15mm.
Further, the height of described rising head sidewall is 205mm.
Further, described rising head outside is provided with heat insulation coating.
From above-mentioned, to description of the present utility model, the utility model, for casting the rising head of gear ring, adopts unique structure, and the gear ring of casting by this rising head can avoid occurring that large area is loose, improves the yield rate of gear ring blank.
Accompanying drawing explanation
Fig. 1 is that the utility model specific embodiment is for casting the structural representation of the rising head of gear ring.
Fig. 2 is that the utility model specific embodiment is for casting the side view of the rising head of gear ring.
The specific embodiment
Below by the specific embodiment, the utility model will be further described.
Shown in Fig. 1, Fig. 2, a kind of for casting the rising head 1 of gear ring, described rising head is connected in for casting sand casting mould 2 tops of gear ring, rising head 1 comprises bottom 11, sidewall 12 and roof 13, this rising head 1 is oval column construction, the length of side of its bottom 11 cross sections is that the hem width of 234mm, bottom 11 cross sections is 124mm, and structure, the size of roof 13 cross sections are identical with bottom 11, and the height of rising head sidewall 12 is 300mm.Rising head 1 sidewall 12 outsides are provided with heat insulation coating.The gear ring of casting by this rising head, can avoid occurring that large area is loose, improves the yield rate of gear ring blank.
Above are only a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
