Abstract

The utility model relates to a roller for a thin iron machine, belonging to a part of the thin iron machine for the cold working of thin iron plates. The utility model is characterized in that the external surface of a hollow shaft is provided with two to six rolling-shaped mould lines which surround circles. When the utility model is installed on the thin iron machine, folding, groove pressure, embossing, shearing, and other technology can be accomplished for the thin iron plates. The utility model has the advantages of one roller with multiple functions, material saving, reduced cost, convenient use, etc.

Description

A kind of iron machine roll

The utility model relates to a kind of part of iron machine of cold working sheet iron.

Iron machine is to be used to process the machinery of thickness less than 0.5 millimeter iron plate.Two axles that are parallel to each other are mechanically arranged, a pair of relatively turnable roll (be commonly referred to as and chew son) has been installed above.Have on the circumference of every breaker roll a pair of mutually coincide roll the shape loft, promptly the loft on roller is the convex tendon that a trap is closed; Another then is the groove that a trap is closed.Two rolls relatively rotate during work.Thin plate moves along the common tangent directions of two circles in the middle of two rollers, under the rolling of two rollers, finishes technologies such as flanging to thin plate, indent, embossing, shearing.The weak point of this machinery is that a kind of technology of every conversion will be changed a pair roller.

The purpose of this utility model is to want the structure of breaker roll to be improved, and makes it to accomplish the many usefulness of a roller, thereby can reduce roll quantity, saves material, reduces cost, the convenient use.

This new design of Roller scheme is to process multiple tracks on the circumference with a roller in two rolls and roll the shape loft.Just passable during work as long as change another roll according to technological requirement.Key problem in technology is, is that the loft with a roller in two rolls is designed to the 2-6 bar, also can more.Loft can be groove or convex tendon, and its cross sectional shape can be dihedral, square, circular arc or other shaped forms etc.

The utility model has the advantages that, the many usefulness of a roller, thus reduced roll quantity, saved material, reduced cost, also made things convenient for use.

Embodiment 1 is shown in figure (1).At the outer surface of a hollow shaft, around circumferential arrangement five channel form roll the shape loft, the cross sectional shape of loft has dihedral, square, circular arc respectively, left end is the smaller multidiameter of diameter.

Embodiment 2 is shown in figure (2).Its shape loft that rolls is several convex tendons around circumference.

Claims

1, a kind of iron machine roll belongs to the part of the iron machine of cold working sheet iron, it is characterized in that: have the 2-6 bar to roll the shape loft around circumference at the outer surface of a hollow shaft.

2, by the described a kind of iron machine roll of claim 1, it is characterized in that: rolling the shape loft is groove, and the cross section of groove can be dihedral, square, shaped form.

3, by the described a kind of iron machine roll of claim 1, it is characterized in that: rolling the shape loft is convex tendon, and the cross section of convex tendon can be angle table, square, shaped form.
