Description

A kind of stud of variable thickness

Technical field

The utility model relates to casting technology fields, more specifically, it relates to a kind of stud of variable thickness.

Background technique

Casting is produced by casting process, and for iron casting, the material for casting mold cavity is sand core, sand Core is the sand lump made of after the refractory materials such as quartz sand, chromite sand, nice foundry sand and organic resin mixed hardening, Foundry Production Process be by a number of assembly of sand core into a sand core group, inside forms a cavity, the shape and casting shape of cavity Shape is identical, and the type that the iron silicon carbon alloy casting of the liquid of fusing is entered sand core is intracavitary, and liquid alloy is full of the sky of sand core internal Chamber shakes after iron silicon carbon alloy solidifying phase is turned into solid-state cast iron or beats sand core to be allowed to fragmentation defeated and dispersed, casting exposes, clearly Reason is clean, that is, completes the production of casting.

Intensity is very high at normal temperature for sand core, but in casting, liquid iron silicon carbon alloy temperature is up to 1400 degree or so, in liquid Before state alloy graining, it is indeformable that sand core must withstand high temperature guarantee.In the actual production process, some sand cores due to by Shape limitation can not support buoyancy and high-temperature baking and the modification that generates of sand core own wt or liquid alloy, cause to cast Part shape changes, and causes casting to scrap when serious.It, generally can be in sand core in order to guarantee that sand core is indeformable before casting formation Certain position installations are supported to enhance the non-deformability of sand mold, this support part is known as " stud ".As shown in Figure 1, needing The left end sand core A in " stud " support is set on lower sand core B.For cast iron part, stud is made of mild steel, and stud exists Sand core is supported before liquid alloy solidification, stud welding does not further take out in casting after solidification, combines together with casting.

Stud is a kind of common important Foundry Production part, and traditional stud can be commercially available, and structure is usually It is made of two panels round or rectangular steel disc and steel column, as shown in Fig. 2, tradition stud D is arranged in parallel by two panels steel disc and forms one Fixed thickness has one or more support column between two panels steel disc, and support column is welded as a whole with steel disc, and traditional stud D is batch Amount production, thickness is the same.Traditional stud D due to the characteristic of structure determine its thickness be it is nonadjustable, due to casting The complexity of part shape, some new products, the sand cores of castings gap of non-batch production are varied, in casting group core, tradition Often unqualified thickness is suitable by stud D.

Utility model content

The technical problems to be solved in the utility model is the above-mentioned deficiency for the prior art, the purpose of this utility model one There is provided a kind of studs that can adjust the variable thickness that thickness, structure are simple, application is strong.

The technical solution of the utility model is: a kind of stud of variable thickness, including pedestal, is equipped with above the pedestal The bracket of two parallel arrangements, bracket one end described in two is respectively equipped with the bending part connecting with described pedestal one end, institute Pedestal, bracket, the bending part stated are that steel wire is made, and are integrally formed between the pedestal and the bracket, bending part Structure.

As a further improvement, the pedestal is monosymmetric U-shaped structure.

Further, the bracket is parallel with the pedestal.

It further, is U-shaped structure between the bracket and the bending part, pedestal.

Further, the extension end of the bracket is concordant with the other end of the pedestal.

Beneficial effect

The utility model compared with prior art, has the advantage that are as follows: the core of the utility model is made up of steel wire bending Support, can be adjusted flexibly thickness, and structure is simple, and amalgamation is good, have preload pressure, and stability of strutting system is good, can make, and make Simply, application is strong.

Specific embodiment

Specific embodiment in reference to the accompanying drawing is described further the utility model.

Refering to fig. 1-6, a kind of stud of variable thickness, including pedestal 1, set that there are two the branch being arranged in parallel above pedestal 1 Frame 2, two 2 one end of bracket are respectively equipped with the bending part 3 connecting with 1 one end of pedestal, and pedestal 1, bracket 2, bending part 3 are steel wire It is made, is integrally formed structures between pedestal 1 and bracket 2, bending part 3；Steel wire uses mild steel wire, and steel wire can be according to sand core Weight selects different diameters to meet the support force of different weight sand core.

In the present embodiment, pedestal 1 is monosymmetric U-shaped structure, and the production is simple and convenient, the good bracket 2 of stability and bottom Seat 1 is parallel, is U-shaped structure between bracket 2 and bending part 3, pedestal 1, the extension end of bracket 2 is concordant with the other end of pedestal 1, bottom Seat 1 and bracket 2 and the contact area of sand core are big, and stability of strutting system is good, if necessary to adjust the thickness of stud, need to only adjust bending The open height in portion 3, it is convenient and simple, meanwhile, U-shaped structure determines that thickness direction has pico- elasticity, this small amount of bullet Property can be used as the preload pressure of support, prevent stud from sliding or being washed away by flowing aluminium alloy, guarantee the precision and stability of sand core, To guarantee the q&r of casting.

A kind of production method of the stud of variable thickness, including steps are as follows,

S1, one Duan Gangsi of interception, bend to U-shaped structure with doubling in the middle part of steel wire, obtain pedestal 1；

S2, two sections of parallel steel wire doublings of pedestal 1 are bent into two U-shaped structures side by side, obtains two brackets 2 and two A bending part 3；

S3, the open height that bending part 3 is adjusted according to actual thickness requirement.

The practical application of the utility model is as Figure 4-Figure 6, and stud C is placed on hanging between sand core A and lower sand core B Position can effectively support sand core A, prevent sand core A from deforming, and stud C can be according between upper sand core A and lower sand core B The thickness of gap field fabrication, stud C live can also adjust.

The stud of the utility model is made up of steel wire bending, thickness can be adjusted flexibly, structure is simple, and amalgamation is good, tool There is preload pressure, stability of strutting system is good, can make, and production is simple, and application is strong.

Above are merely preferred embodiments of the utility model, it should be pointed out that for those skilled in the art, Under the premise of not departing from the utility model structure, several modifications and improvements can also be made, it is practical new that these all will not influence this The effect and patent practicability that type is implemented.
