Abstract

The invention discloses a molding process of rolling mill housing products, which has the technical scheme that: (1) dividing regions and blocks according to the structure of a mill housing product, then manufacturing a block model, and (2) manufacturing a horizon and marking a central line; drawing the outline of the product on the horizon according to the drawing process size; (3) placing the first, second and third modules according to the contour lines, firmly pressing and fixing, then filling sand and impacting the shape, and completing the sand impacting of the shape by the movement of the first model block, the second model block and the third model block model, (4) placing the fourth model block after the sand impacting of the shape is completed, and completing all internal sand molds; (5) finally, casting upper boxes, painting and buckling boxes are manufactured. The invention realizes the purposes of improving the production efficiency of rolling mill housing products and reducing the production cost.

Description

Modeling process of rolling mill housing products

Technical Field

The invention relates to a casting processing technology, in particular to a molding technology suitable for rolling mill housing products.

Background

The traditional model of the mill housing (frame) is manufactured into an integral real sample, and a corresponding draft angle (which meets the standard JB/T5101-1991) is required to be arranged for drawing, so that the process model has high cost and long manufacturing period, seriously influences the processing progress and the processing cost of the mill housing products, and is not beneficial to the high-efficiency production of the mill housing products.

Disclosure of Invention

The invention aims to provide a modeling process of a rolling mill housing type product, which has reasonable process and convenient and fast processing.

The technical scheme of the invention is that the molding process of rolling mill housing products is characterized in that: (1) dividing regions and blocks according to the structure of the mill housing type product, then manufacturing block models, and completing the manufacture of a mill housing type product cavity by moving each block model, (2) firstly manufacturing a horizon and marking a central line; drawing the outline of the product on the horizon according to the drawing process size; (3) placing a first model block, a second model block and a third model block according to contour lines, firmly pressing and fixing, then filling sand and impacting the shape, and impacting the sand of the shape by moving the first model block, the second model block and the third model block; (5) finally, casting upper boxes, painting and buckling boxes are manufactured.

Preferably, the rolling mill housing type product is divided into four model blocks, wherein the first model block is a bottom module, the second model block is a middle module, the third model block is a strip module, and the fourth model block is a center module.

The part of the first model block close to the middle position is 5-10 mm more than one half of the whole length of the bottom of the rolling mill housing type product to be cast.

The invention can greatly reduce the manufacturing cost of the process model of the rolling mill housing (frame) by about 50 percent, shorten the manufacturing period of the model by 40 to 50 percent, particularly has better application effect on non-batch products, and can greatly improve the production efficiency of the rolling mill housing products and reduce the production cost.

Detailed Description

The embodiment is described in detail by combining the attached drawings, and the modeling process of the rolling mill housing products comprises the steps of (1) dividing the rolling mill housing products into regions and blocks according to the structures of the rolling mill housing products, then manufacturing block models, and completing the manufacturing of a rolling mill housing product cavity by moving each block model, (2) firstly manufacturing a horizon and marking a central line; drawing the outline of the product on the horizon according to the drawing process size; (3) placing a first model block 1, a second model block 2 and a third model block 3 according to contour lines, firmly pressing and fixing, then filling sand and impacting the shape, and completing the impacting of the shape through the movement of the first model block, the second model block and the third model block and the data of scales of mill housing type products, (4) placing a fourth model block 4 after the impacting of the shape is completed, and completing all internal sand molds; (5) finally, manufacturing a casting upper box, painting and buckling a box; preferably, the rolling mill housing type product is divided into four model blocks, wherein the first model block is a bottom module, the second model block is a middle module, the third model block is a strip module, and the fourth model block is a center module; the part of the first model block close to the middle position is 5-10 mm more than one half of the total length of the bottom of the rolling mill housing class product to be cast, so that when the first model block reversely manufactures the bottom of the other half of the rolling mill housing class product to be cast, a gap between two different models can be completely closed, and cracks are prevented from appearing in the models of the rolling mill housing class product to be cast.

When the rolling mill housing is used, the ground configuration of rolling mill housing products can be completed quickly and efficiently, and the use cost and the processing cost are low.

The above examples are merely illustrative for clarity and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. It is not necessary or necessary to exhaustively enumerate all embodiments herein, and obvious variations or modifications can be made without departing from the scope of the invention.
