The upper box body covers the upper end of the lower box body, lugs are arranged on opposite side walls of the lower box body and the upper box body, a through hole is arranged on the side wall of each lug, a prying lever is inserted into the through holes, positioning holes are arranged at four corners of each of the upper box body and the lower box body, and positioning pins penetrate through the positioning holes to fix the upper box body and the lower box body. The casting sandbox for steel balls is simple in structure, the through holes are arranged on the four corners of each of the upper box body and the lower box body, the casting sandbox is positioned through the positioning pins, the lugs are provided with the through holes, the upper box body and the lower box body can be pried open by the aid of the prying lever, and the casting sandbox is convenient and rapid in operation.
Description
Technical field:
The utility model relates to steel ball and makes the field, relates in particular to a kind of steel ball with the casting sandbox.
Background technology:
Steel ball casting (cast grinding ball) is that factories for steel balls is utilized the middle frequency furnace heat temperature raising with waste and old furnace charges such as steel scrap, scrap iron; Making it furnace charge fully melts; Add in right amount that in the middle of the furnace charge fusion process to carry out chemical analysis in noble metal alloy (like ferrochrome, ferromanganese, vanadium iron etc.) to the stove modified, treat molten iron temperature reach more than 1550 ℃ and satisfy the process stipulation requirement after with qualified molten iron pouring in ball swage or steel ball production line mould.Just the steel ball that produces of the way through casting smelting is called steel ball casting (cast grinding ball).
Steel ball casting is divided into according to material: high-chromium alloy casting ball, multielement alloy cast ball, low chrome casting ball.
The sandbox of using in the production process for steel ball casting; Previous sandbox is to be provided with locating hole in upper box corner; The corner of lower box is provided with reference column; This last lower box that matches, the casting back is difficult to separately, and reference column can be because long-term wearing and tearing cause reference column to fracture in locating hole in addition.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of steel ball with the casting sandbox, and is simple in structure, will go up lower box easily separately, and continuing of being convenient to produce carries out.
The technical scheme of the utility model is following:
Steel ball is with the casting sandbox; Comprise lower box, upper box, upper box is stamped in the lower box upper end, and it is characterized in that: the relative sidewall of lower box and upper box is fixed with lug respectively; Have through hole on the lug sidewall; Be inserted with in the through hole and stick up bar, four corners of upper and lower casing have locating hole, have alignment pin to pass the fixing lower box of going up of described locating hole.
Described steel ball is characterized in that with the casting sandbox: it is stainless steel that described alignment pin adopts material.
The utility model has the advantages that:
The utility model is simple in structure, has through hole at corresponding four turnings of last lower box, through the alignment pin location, on lug, is provided with through hole simultaneously, breaks lower box into two with one's hands through sticking up bar, and is convenient to operation.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Steel ball comprises lower box 1, upper box 2 with the casting sandbox, and upper box 2 is stamped in lower box 1 upper end; The relative sidewall of nowel 1 body and upper box 2 is fixed with lug 3 respectively; Have through hole on lug 3 sidewalls, be inserted with in the through hole and stick up bar 4, four corners of upper and lower casing 1,2 have locating hole 5; Have alignment pin 6 to pass the locating hole 5 fixing lower boxes 1,2 of going up, it is stainless steel that alignment pin 6 adopts material.
