Abstract
The present invention relates to a casting method for a shovel-blocking plate grooved side of a scraping plate conveyor used for coal mines. The method comprises the steps that a half side mould is manufactured according to the shape and the size of a groove in a wood plate of which the thickness is greater than the groove depth of the concave surface of the shovel-blocking plate grooved side; the surface of the wood plate is used as a parting surface; a sand box is placed on a mould surface of the wood plate and is filled with sand; a convex sand mould formed from the half side mould can be formed after mould drawing, and the convex sand mould is used as a lower sand box; the half side mould is manufactured firstly according to a conventional method for a convex surface and is filled with sand, a concave sand mould formed from the half side mould can be formed after mould drawing, the concave sand mould is used as an upper sand box, the lower sand box and the upper sand box are assembled together and are cast with molten steel, and a finished product of the shovel-blocking plate grooved side is manufactured. Compared with a traditional method, the present invention does not need a lower core to manufacture a loose piece and has the advantages of simple operation and high productive efficiency. Particularly, the high precision of the manufactured shovel-blocking plate grooved side can meet actual demands.
Description
One, technical field
The present invention relates to the casting method of the retaining shovel board ledge in mining machinery field, particularly slat conveyer.
Two, background technology
Retaining shovel board ledge is the foundry goods of mine flight conveyer, and as shown in Figure 1, this foundry goods is a mono-block cast, its complex structure, and the dimensional characteristic height, casting is got up very difficult.We can see that this foundry goods left side is the fitfull projection from Fig. 1, the right side be present on a plane numerous irregular recessed, the middle part is then concavo-convex staggered, thereby if method is routinely cast, can't find suitable die joint (promptly opening the limit) at all.Fig. 2 is a scheme drawing of casting this foundry goods according to conventional approach, be foundry goods 6 partly shown in the figure section line, the way that we adopted be with concavo-convex staggered face directly the part of molding all make fuse or loose piece 5, guarantee that with this die joint 4 is a plane and can operating, existing problem is recessed, convex portion is too many, thereby fuse, loose piece is very many, gap therebetween or dislocation meeting bring very big difficulty to operation, and the weight of wooden model also increases greatly, coremaking is very big with the work capacity of following fuse, cast retaining shovel board ledge precision can not reach the technical requirements of product, therefore in fact this casting technique can not adapt to the requirement of production.
Three, summary of the invention
Task of the present invention provides that a kind of production technology is simple, work capacity is little, casting accuracy is high is used for producing the method for the retaining shovel board ledge of slat conveyer specially.
Technical scheme of the present invention is as follows:
The casting method of shelves shovel board ledge, it is characterized in that having taked following measure, in the plank of a thickness greater than the depth of groove of retaining shovel board ledge recessed face, make this one side of something model according to the geomery of groove, be die joint with this plank plane then, sandbox be placed on the model face of this plank, tamp sand, just can form sand mold after the molding by the formed convex of this one side of something model, and with this as drag falsk; Then manufacture this half of model earlier for crowning, tamp sand then, just can form the sand mold of the formed invaginated type of this one side of something model after the molding according to conventional approach, with this as cope box, itself and drag falsk are assembled together, and the casting molten steel just can make the finished product that keeps off the shovel board ledge.
Owing to adopted abovementioned technology, thereby can avoid time fuse fully, do loose piece, not only simple to operate, production efficiency is high, and can make the technical requirements of satisfying of the retaining shovel board ledge produced.
Four, description of drawings
Fig. 1 is the shape scheme drawing of described retaining shovel board ledge, also is the shape scheme drawing of model of the present invention;
Fig. 2 is a method scheme drawing of producing retaining shovel board ledge with prior art.
Five, specific embodiment
The casting method of retaining shovel board ledge is as follows:
In the plank of a thickness greater than groove 7 degree of depth of retaining shovel board ledge recessed face 2, make this one side of something model according to the geomery of groove, be die joint with this plank plane then, sandbox is placed on the model face of this plank, tamp sand, just can form sand mold after the molding by the formed convex of this one side of something model, and with this as drag falsk; Manufacture this half of model for 3 of crownings earlier according to conventional approach, tamp sand then, just can form the sand mold of the formed invaginated type of this one side of something model after the molding, with this as cope box, itself and drag falsk are assembled together, and the casting molten steel just can make the finished product that keeps off the shovel board ledge.
Claims (1)
1, the casting method of retaining shovel board ledge, it is characterized in that taking following measure: in the plank of a thickness greater than the depth of groove of retaining shovel board ledge recessed face, make this one side of something model according to the geomery of groove, be die joint with this plank plane then, sandbox is placed on the model face of this plank, tamp sand, just can form sand mold after the molding by the formed convex of this one side of something model, and with this as drag falsk; Then manufacture this half of model earlier for crowning, tamp sand then, just can form the sand mold of the formed invaginated type of this one side of something model after the molding according to conventional approach, with this as cope box, itself and drag falsk are assembled together, and the casting molten steel just can make the finished product that keeps off the shovel board ledge.
