Abstract
The invention provides production equipment of rectangular steel pipes with sharp angles. The equipment comprises a roughly-moulding mechanism, a first Turkey head straightener, and a second Turkey head straightener, wherein the roughly-moulding mechanism, the first Turkey head straightener, and the second Turkey head straightener are connected in sequence head-to-tail. The production equipment has a simple structure, and is capable of carrying out processing and connecting in one step without welding.
Description
Technical field
The present invention relates to cold-rolled forming section process equipment field, especially relate to a kind of printed angle rectangle section steel pipe production equipment.
Background technology
Cold-rolled forming section is the one in numerous rolling shapes, and the band steel of one fixed width, through the roll of one group of longitudinal arrangement under normal temperature condition, is progressively out of shape, and reaches the geomery meeting instructions for use, and then by welding fabrication, this product is exactly cold-rolled forming section.Because needs carry out soldering, cause operating efficiency ground, finished product yield low, do not meet the demand of modern production.
Summary of the invention
The object of this invention is to provide a kind of structure simple, can by a kind of printed angle rectangle section steel pipe production equipment of welding processing printed angle rectangle section steel pipe.
Technical scheme of the present invention is:
A kind of printed angle rectangle section steel pipe production equipment, comprise thick shaping mechanism, the first turks-head roll straightener and the second turks-head roll straightener, described thick shaping mechanism, the first turks-head roll straightener are connected successively with before and after the second turks-head roll straightener,
Described thick shaping mechanism comprises support and several roll stacks, described roll stacks is made up of upper and lower two rolls, described roll stacks is flat pattern arrangement successively laterally, and be fixed on support, the radial direction of the outer surface of described roll is provided with groove, the shape of cross section of described groove, often organizing equal difference on roll, crossfades into V-shaped face by arc-shaped surface from front to back successively
Described first turks-head roll straightener comprises the two head rollers to symmetry that cross is arranged, in concave arc shape in the middle part of the roller limit of a wherein correct roller, both sides are the hypotenuse of 45° angle degree, be provided with a right angle step afterwards again, in concave arc shape in the middle part of the roller limit of another correct roller, both sides are the hypotenuse of 45° angle degree, are provided with two right angle steps afterwards again
Described second turks-head roll straightener comprises the two head rollers to symmetry that cross is arranged, linearly shape in the middle part of the roller limit of a wherein correct roller, both sides are the hypotenuse of 45° angle degree, be provided with a right angle step afterwards again, linearly shape in the middle part of the roller limit of another correct roller, both sides are the hypotenuse of 45° angle degree, are provided with two right angle steps afterwards again.
The advantage that the present invention has and good effect are: structure simply, does not need to process connection further by welding.
