Abstract

The utility model provides a production line of a section bar with the middle part being bent so that the section bar with the middle part being bent can be continuously produced with low cost. The production line comprises a plate conveying line, wherein the plate conveying line is sequentially provided with a plurality of sets of rolling equipment along the conveying direction of the plate conveying line, and the plurality of sets of rolling equipment are composed of upper forming rollers and lower forming rollers. A roller body of each lower forming roller is provided with one or more forming footsteps along the axial direction. The forming included angle between the side face of each forming footstep, corresponding to the same forming angle, in different lower forming rollers and the axis of the roller body of each lower forming roller decreases gradually along the conveying direction of the plate conveying line. The cross-section shape of each upper forming roller coincides with the cross-section shape of each lower forming roller. The positions of the forming footsteps, corresponding to the same forming angle, on the lower forming rollers are the same. By means of the production line of the section bar with the middle part being bent, equipment cost and human cost are lowered, moreover, the length of the produced section bar can not be limited, and therefore good practicability can be achieved.

Description

A kind of production line of middle part bending section bar

Technical field

The utility model belongs to section bar manufacturing technology field, specially refers to a kind of production line of middle part bending section bar.

Background technology

At present, section bar has been widely used in building trade and metal structure, and as factory building, bridge, boats and ships, agricultural vehicle manufacturing, electric power pylon, Transport Machinery etc. mainly comprise aluminium section bar and shaped steel etc.Existing section bar all is to produce by the method for punching press or extruding, the investment of production equipment height of extruding, and be difficult to adjust its shape; Though the method for punching press is fairly simple, but the length of section bar is subjected to the restriction of pressing equipment, be difficult to the long section bar of production length, in addition, the punching press of section bar needs a plurality of impact devices to work in coordination, equipment investment is also bigger, and the necessary operations workman is many aborning, and human cost is higher.

Summary of the invention

The purpose of this utility model is the production line that proposes a kind of middle part bending section bar, to realize low cost, to produce the section bar of middle part bending continuously.

The production line of bending section bar in middle part of the present utility model comprises the sheet material pipeline, and key is that described sheet material pipeline is aligned in sequence with the rolling equipment that many covers are made of last format roll and lower forming roller along its throughput direction; The roll body of described lower forming roller is provided with one or more moulding steps vertically, and in the different lower forming rollers between the side of the moulding step of corresponding same forming angle and the lower forming roller roll body axis formed moulding angle reduce gradually along the throughput direction of sheet material pipeline, the described cross sectional shape of going up format roll conforms to the cross sectional shape of lower forming roller; The moulding step of corresponding same forming angle is identical in the position of lower forming roller.

When sheet material passes through between last format roll and the lower forming roller, sheet material can be extruded the bending that conforms to the moulding step by the moulding step of last format roll and lower forming roller, and can gradually this angle bending be reduced gradually through a plurality of rolling equipments, thereby produce the section bar with bending, to satisfy different requirement of client.In addition, by a plurality of rolling equipments this angle bending is reduced gradually, can avoid bending angle excessive and cause sheet material can't pass through rolling equipment, and can utilize less roller pressure the sheet material bending can have been reduced the requirement to rolling equipment.

Further, the moulding angle of the moulding step of the described lower forming roller that is arranged in sheet material pipeline rearmost position along throughput direction is the right angle, to produce modal sheet material with right angle bending.

The production line of bending section bar in middle part of the present utility model passes through the continuous bending of sheet material, make sheet material form section bar, a whole set of apparatus for production line investment is little, the necessary operations workman is fewer aborning, equipment cost and human cost have been reduced, and the length of the section bar of producing is unrestricted, and the concrete shape of section bar can be easy to by top roll, the lower roll that changes each rolling equipment change, and therefore has good practicability.

The specific embodiment

Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.

Embodiment 1:

As shown in the figure, the production line of the middle part of present embodiment bending section bar comprises the sheet material pipeline, and the sheet material pipeline is aligned in sequence with the rolling equipment that many covers are made of last format roll 1 and lower forming roller 2 along its throughput direction; The roll body of described lower forming roller 2 is provided with a moulding step 3 vertically, and in the different lower forming rollers between the side of corresponding moulding step 3 and the lower forming roller 2 roll body axis formed moulding angle α reduce gradually along the throughput direction of sheet material pipeline 1, the described cross sectional shape of going up format roll 1 conforms to the cross sectional shape of lower forming roller 2; The moulding step 3 of corresponding same forming angle is identical in the position of lower forming roller 2.

When sheet material 4 passes through between last format roll 1 and the lower forming roller 2, sheet material 4 can be extruded the bending that conforms to moulding step 3 by the moulding step 3 of last format roll 1 and lower forming roller 2, and can gradually this angle bending be reduced gradually through a plurality of rolling equipments, thereby produce the section bar with bending, to satisfy different requirement of client.In addition, by a plurality of rolling equipments this angle bending is reduced gradually, can avoid bending angle excessive and cause sheet material can't pass through rolling equipment, and can utilize less roller pressure the sheet material bending can have been reduced the requirement to rolling equipment.

Further, the moulding angle α of the moulding step 3 of the described lower forming roller that is arranged in sheet material pipeline rearmost position along throughput direction is the right angle, to produce modal sheet material with right angle bending.

The production line of above-mentioned middle part bending section bar passes through the continuous bending of sheet material, make sheet material form section bar, a whole set of apparatus for production line investment is little, the necessary operations workman is fewer aborning, equipment cost and human cost have been reduced, and the length of the section bar of producing is unrestricted, and the concrete shape of section bar can be easy to by top roll, the lower roll that changes each rolling equipment change, and therefore has good practicability.
