Abstract
The invention relates to a production method of cold bend B type steel. A steel belt is cut by the steps of: firstly, sending the steel belt to a precutting press according to the required length by an automatic feeding machine, and oppositely cutting two sides of the steel belt, corresponding a bent part of the steel belt, to form pre-cuts by using the precutting press; and secondly, fully shearing the residual part of the steel belt at the pre-cuts formed in the first step by using a shearing machine after the B type steel is subjected to cold roll forming so that the final product is formed. In the production method of the cold bend B type steel, the residual part of the steel belt at the pre-cuts is fully sheared by using the shearing machine after formed, therefore, hollow cylinder bodies at two sides of the B type steel are kept off during cutting, and section quality of the steel is ensured; and all production procedures are connected to form a streamline operation through a precutting procedure, continuous production of the B type steel is realized so that production efficiency, quality and size stability of the B type steel are remarkably improved, and cost and rejection ratio are remarkably reduced.
Description
Technical field
The invention belongs to shape forming technique field, definite saying so relates to the method for producing that a kind of section is the Type B steel of B shape.
Background technology
The Type B steel is to gain the name because the shape of sectional shape is similar to capitalization English letter B, and it mainly is to pass through the roll-in cold roll forming with steel bands such as hot rolling, zinc-plated, cold rolling or color coatings.As the disclosed Type B steel construction of Chinese utility model patent open file CN 2918958Y, this Type B steel has a plane, is respectively arranged with two hollow cylinder structures of opposing parallel at the two ends of the relative one side in this plane.The production method of this Type B steel of existing production is to send into the roll squeezer cold bending again after earlier steel band being cut off by Len req, also need weld on the butt joint plane between two hollow cylinders after the shaping and could finally form product.This production method makes that the speed of production of Type B steel is slower, is difficult to form the operation of high-efficiency stream line between the production equipment of each operation, causes its production efficiency lower, and adopts welding procedure to cause its production cost higher, is unfavorable for the market competition of product.
Summary of the invention
The objective of the invention is: provide a kind of production method of clod wash Type B steel, to solve the existing problem that Type B steel production efficiency is low, production cost is high.
Technical scheme of the present invention is: a kind of production method of clod wash Type B steel, this method is that blocking in two steps of steel band carried out: the first step is steel band to be sent in the pre-bicker by Len req by autoloader, punches out pre-otch by pre-bicker relatively at corresponding its bending part in the both sides of steel band; Second step was that the Type B steel is all cut off the remainder of steel band in the pre-incision that the first step forms with cutter behind cold bending again, thereby formed final products.
The length of the pre-otch in described steel band both sides respectively with the dogleg section equal in length of the section bar that will be shaped, stay the width of width of steel band of establishing and the section bar that will be shaped to equate between the two pre-otch.
Need behind the described Type B steel cold bending earlier by the roll-in sewing machine after stamping out the concavo-convex crimping structure that cooperates on the butt joint plane between two hollow cylinders and the substrate, to send in the cutter again.
Described steel band adopts the automatically continuous blowing of uncoiler.
Described autoloader cooperates by device for detecting length with pre-bicker surveys long, fixed length feeding automatically.
Behind cutter, also be connected with automatic delivery device.
Described steel band enters the feeding mouth of clod wash roller pressing forming machine after by the correcting of automatic guiding device again.
Described thickness of strips is the 0.3-1.5 millimeter.
Clod wash Type B steel production method of the present invention be with blocking of steel band be divided into two the step carry out, the bending part of corresponding steel band punches out pre-otch in the steel band both sides earlier, make width between the two pre-otch be equivalent to the width of Type B steel, the remainder of steel band is all cut off in pre-incision by cutter again after the moulding, thereby when blocking, avoided the hollow cylinder of Type B steel both sides, guaranteed the cross section quality of shaped steel, by pre-die-cut operation each production process is connected into pipelining, realized the continuous production of Type B steel, make production efficiency of products, quality and dimensional stability have had significant raising, and cost and percent defective significantly reduce, and provide good basis to improving the competitiveness of product in market.
