CN201246439Y - Counterweight iron with welding casing - Google Patents

Abstract

The utility model provides a counterweight iron with a casing welded by rolled steel, which is characterized by firstly designing according to the size of the counterweight iron, blanking with rolled steel plates for welding together, forming the casing of the counterweight iron, then pouring molten iron, welding and flattening steel plates after molten iron cooling, and finally obtaining finished products via slightly neatening. The surface of the counterweight iron is flat, each iron has accurate weight, the appearance quality of the products is fine, and the utility model can save energy.

Description

A kind of balance weight iron that welds shell that has

Technical field

The utility model relates to the balance weight iron that machinery is used, particularly a kind of balance weight iron that welds shell that has.

Background technique

On the heavy mechanical equipment, because of need of work is furnished with balance weight iron.This balance weight iron is normally cast an integral body with the method for casting, but because the narrow limitation of casting technique, is difficult to control boundary dimension, surface quality and the weight of foundry goods, and outward appearance is very slightly made, and has had a strong impact on quality of product.Adopt artificial polishing method to eliminate defective, time-consuming, can not obtain well-content effect.

Summary of the invention

The purpose of this utility model is to propose a kind of balance weight iron that has with the shell of Rolled Steel welding, its surfacing, and every weight is accurate, and the product appearance quality is fine.

The utility model is to realize like this.At first press the design size of balance weight iron, the steel plate cutting with rolling welds it, forms the balance weight iron shell, carries out pouring molten iron again, and is flat with steel deck-plate welding envelope after cooling, arrangement a little, the good balance weight iron of appearance quality.

Because the welding shell is to be welded with rolling steel plate, does not have defectives such as pore overlap burning into sand, so the balance weight iron appearance quality of making is fine.The protection of welding shell is arranged, do not need to make the sand mold of cast usefulness during pouring molten iron, also reduced the time-consuming work that foundry goods must be polished, energy saving.

Description of drawings

Fig. 1 is the utility model original design external form schematic representation,

Fig. 2 is the shell schematic representation of the utility model with rolling steel plate cutting welding.

Wherein 1----welds shell, 2----ingot bar, 3----lacing wire.

Embodiment

Find out from Fig. 1, Fig. 2, the utility model mainly is that welding shell (1) and ingot bar (2) are formed, at first press the configuration design size of balance weight iron, with rolling steel plate cutting, its welding is formed the profile balance weight iron shell (1) the same with design size, and pouring molten iron generates ingot bar (2) within it again, and is flat with steel deck-plate welding envelope after cooling, a little the arrangement, the good balance weight iron of the accurate appearance quality of weight.

Indeformable when the pouring molten iron for guaranteeing shell, in the shell several reinforcement plates can be set.

Claims (1)

1, a kind of balance weight iron that welds shell that has, mainly be that welding shell (1) and ingot bar (2) are formed, it is characterized in that rolling steel plate welding is formed the profile balance weight iron shell (1) the same with design size, portion is provided with the pig iron ingot bar (2) of lacing wire (3) and cast within it, is provided with to be used to weld the flat steel deck-plate of envelope on balance weight iron shell (1).
