Technical field
The utility model is related to casting sand core positioning device technical field more particularly to a kind of monoblock type studs.
Background technology
In various large and medium-sized casting, various elongated pipeline configurations are often had, often diameter is smaller for these pipelines, length
But very long, length-to-diameter is frequently more than 20, even greater than 100.When casting these pipelines, to prevent pipeline sand core
It occurs bending and deformation, needs to fix sand core using stud, it is ensured that sand core is located at the center of sand mold chamber so that the pipe of casting and forming
Road has accurate size.
It is generally necessary to pipeline sand core is supported and fixed from the multiple directions of sand core circumferential direction, and it is multiple in the axial direction of sand core
Stud is arranged to avoid sand core from occuring bending and deformation in position.It is placed using stud when traditional stud supporting pipeline sand core very tired
Stud is bundled on pipeline sand core by difficulty, common thin wire, or uses iron sheet plug jail stud.Stud is placed using these methods not
It is very poor only to operate very difficult and reliability, often occur in casting process stud fall off, shifting phenomena, to stud lose
The effect for going positioning to support, pipe core occur bending and deformation, and cause casting pipeline the deformation even undesirable condition of wall-through occur, most
Casting is caused to be scrapped eventually, the production poor quality of casting increases production cost.
Utility model content
Technical problem to be solved in the utility model and the technical assignment of proposition are improved to the prior art, are provided
A kind of monoblock type stud solves the stud in current technology and places difficulty, and fixation is insecure, and easy displacement falls off, it is difficult to ensure
The problem of pipeline castability.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of monoblock type stud, which is characterized in that including cranse and support portion, the cranse circularizes and is sleeved on pipe
The periphery of road sand core, its circle spacing of the peripheral upper edge of cranse are provided with several support portions with the cooperation of sand mold wall surface.This practicality
The novel integrated core support structure simple and compact, it is easy for installation, quick by being sleeved between cranse on pipeline sand core,
And it will not wave, be bent in casting process to ensure pipeline sand core using support portion, monoblock type stud is mounted on pipe
It is not susceptible to shift after on road sand core or fall off, can remain the positional stability of pipeline sand core, effectively reinforce the pipeline
The integral strength of sand core ensures the quality of cast member, avoids the occurrence of the deformation even undesirable condition of wall-through, improves castability.
Further, there is gap, setting gap is to cast in order to prevent between the inner wall of the cranse and pipeline sand core
Part high temperature of molten metal in casting process causes to thermally expand so that the phase mutual friction between stud and type, core causes casting
Casting burning into sand caused by knockout.
Further, the internal diameter of the cranse is bigger 0.5~1mm than the diameter of pipeline sand core, facilitates installation, and effectively
Fixed support tube road sand core, positioning accuracy are high.
Further, the peripheral end portion of the support portion has gap with sand mold wall surface.
Further, the gap width between the peripheral end portion of the support portion and sand mold wall surface is 0.5~1mm.
Further, the support portion is in the form of a column structure for column structure or support portion main body, and in column knot
The outer end of structure is provided with support plate, and simple in structure, stability of strutting system is good.
Further, the support portion outer end be in the matched cambered surface of sand mold wall surface, improve the stability of support, avoid
Support portion leads to knockout with the interference of sand mold wall surface, improves castability.
Further, the support portion is fixedly connected by welding, riveting or engagement thread with cranse.It is easy to connect,
Stability is good, ensures the fixation accuracy to pipeline sand core.
Further, the material of the monoblock type stud is identical as the material of the pipeline cast, during cast
Monoblock type stud is melted and is melted as entirety by the molten metal of high temperature, and monoblock type stud becomes one of pipeline.
Further, the monoblock type stud is arranged in the axially spaced-apart of pipeline sand core, and spacing is 0.6~1m,
According to the length of pipeline sand core can device several monoblock type studs, effectively avoid pipeline sand core flexural deformation.
Compared with prior art, the utility model advantage is：
Integrated core support structure described in the utility model is simple, compact, can easily be placed, and operating efficiency is high,
And fixation after placing, will not be displaced the situation to fall off, to ensure that the effective position to pipeline sand core supports, keep away
Exempt from pipeline sand core flexural deformation, ensures castability；
The utility model avoids the process that stud fixed position is arranged on pipeline sand core using cranse, not only reduces
Work process, while avoiding and causing casting burning into sand defect caused by knockout when card sets stud, simultaneously because the presence of cranse
Stud is uniformly transmitted in the effect of molten metal high-temperature heat expansion and buoyancy on pipeline sand core, cast tube is avoided
The flexural deformation in road.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
