Abstract
A grinder roll of a flour mill relates to an accessory of mining mechanical equipment, and comprises two parts: a roll collar and a core sleeve positioned in the roll collar, wherein a step positioning hole is formed at one end of the inner hole of the roll collar; a conical central hole is formed on the core sleeve; a positioning step matched with the step positioning hole of the roll collar is formed on the excircle of the small hole end of the conical central hole; mesh-shaped connecting ribs connecting the roll collar and the core sleeve into a whole body are arranged on the core sleeve; the roll collar is made of high-chromium iron; and the core sleeve is made of 20# steel. A poured core sleeve is placed in a grinder roll casting mould, the roll collar is poured out, and then the integral grinder roll undergone twice pouring processes can be made. The grinder roll of the flour mill has the advantages of long service life, safe and reliable use, low cost, high performance price ratio, convenient processing and simple processing procedures, and is very suitable to promote and use for flour mills.
Description
Technical field
The utility model relates to a kind of mine mechanism accessory, particularly a kind of grinding roller of wheat flour-milling.
Background technology
At present, during the manufacturer production grinding roller of wheat flour-milling, mainly be to adopt potassium steel or rich chromium cast iron monoblock cast to form both at home and abroad.If adopt the potassium steel casting, because its wearability is relatively poor, the life-span is shorter, and the user is dissatisfied, and cost performance is not high; If adopt the rich chromium cast iron monoblock cast, then use noble metal more, its price comparison is expensive; And because the conical central hole of grinding roller of wheat flour-milling is to process after heat treatment, and the rich chromium cast iron hardness after the heat treatment is higher, and its processing is difficulty very, and working (machining) efficiency is lower; Certainly, also can be that earlier roughing is carried out in annealing, quench then, carry out fine finishining after the tempering, but will anneal so once more, many roughing once, manufacturing procedure is complicated more, the duration is long.
Summary of the invention
The technical problems to be solved in the utility model is: provide that a kind of production cost is low, working (machining) efficiency is high, the simple grinding roller of wheat flour-milling of manufacturing procedure.
The basic principle that solves the problems of the technologies described above is: existing monoblock type grinding roller of wheat flour-milling is split into collars and core retainer plate two parts, make respectively with different materials, then collars and the core retainer plate that has netted dowel are formed complete parts by second pouring.
The technical scheme that solves the problems of the technologies described above is: a kind of grinding roller of wheat flour-milling, this grinding roller comprise collars and are positioned at core retainer plate two parts of collars that described roll collar inner hole one end is provided with the step locating hole; Described core retainer plate has conical central hole, and is provided with the positioning step that matches with collars step locating hole on the small bore end cylindrical of conical central hole; Also be provided with the netted dowel that collars and core retainer plate are fused on the described core retainer plate, with prevent between issuable collars and the core retainer plate axially and radial-play.
Further technical scheme of the present utility model is: described collars is formed by the high chromium cast iron material manufacturing.
Further again technical scheme of the present utility model is: described core retainer plate is by 20
#Steel is made and is formed.
Described grinding roller of wheat flour-milling is the second pouring monoblock type grinding roller that the core retainer plate that cast earlier is good places grinding roller casting mold and then cast collars to obtain.
Because adopt said structure, the grinding roller of wheat flour-milling of the utility model is compared with existing grinding roller of wheat flour-milling, has following beneficial effect:
1, long service life, safe and reliable:
Because the utility model is to be made of the collars that fuses by cast, core retainer plate, wherein form as the high chromium cast iron material manufacturing that main workpiece-collars is an employing hardness height, wearability is good, both guarantee the serviceability that grinding roller is safe and reliable, can prolong its service life again; In addition, also be provided with the netted dowel that collars and core retainer plate are fused on the core retainer plate, with prevent between issuable collars and the core retainer plate axially and radial-play, therefore, service life of the present utility model is long, and uses also safe and reliable.
2, cost is low:
Because this grinding roller of wheat flour-milling is to be made of collars, core retainer plate, wherein core retainer plate be adopt price comparison cheap 20
Steel is made and is formed, and do not contain any precious metal, thereby it has saved precious metal, reduced production and use cost, adopted the grinding roller of wheat flour-milling of rich chromium cast iron manufacturing to compare with integral body, its material cost is reduced significantly, thereby cost of the present utility model is lower, and cost performance is very high.
3, easy to process:
Because core retainer plate of the present utility model has adopted machinability preferably 20
Steel is made, thereby the processing of its conical central hole is more convenient, thereby can improve working (machining) efficiency greatly.
4, manufacturing procedure is simple:
Because the utility model is to be made of the collars that fuses by second pouring, core retainer plate, therefore, it can save this road heat treatment step of annealing, and its manufacturing procedure is fairly simple, can further improve its working (machining) efficiency and has reduced its processing cost.
Below, the technical characterictic to the grinding roller of wheat flour-milling of the utility model is further described in conjunction with the accompanying drawings and embodiments.
[description of drawings]
Fig. 1: the structural representation of the grinding roller of wheat flour-milling of the utility model:
Among the figure, the label declaration of each major part is as follows:
The 1-collars, 11-step locating hole, the 2-core retainer plate,
The 21-conical central hole, 22-positioning step, the netted dowel on the 23-core retainer plate.
[specific embodiment]
Disclosed among Fig. 1 is a kind of grinding roller of wheat flour-milling, and this grinding roller comprises collars 1 and core retainer plate 2 two parts that are positioned at collars 1, and described collars 1 is formed by the high chromium cast iron material manufacturing, and its endoporus one end is provided with step locating hole 11; Described core retainer plate 2 is by 20
#Steel is made and is formed, and this core retainer plate 2 has conical central hole 21, and is provided with the positioning step 22 that matches with collars step locating hole 11 on the small bore end cylindrical of conical central hole 21; Also be provided with the netted dowel 23 that collars 1 and core retainer plate 2 are fused on the described core retainer plate 2, with prevent between issuable collars and the core retainer plate axially and radial-play; Above-mentioned grinding roller of wheat flour-milling is the second pouring monoblock type grinding roller that the core retainer plate 2 that cast earlier is good places grinding roller casting mold and then cast collars 1 to obtain.
As a kind of conversion of present embodiment, described collars 1 also can adopt the high wear-resistant material of other high rigidity to make.
As another conversion of present embodiment one, described core retainer plate 2 also can adopt other to have preferably the material of machinability and toughness and make.
