Abstract

The utility model provides a production line of a frame-shaped profile provided with a notch, and aims at continuously producing the frame-shaped profile provided with the notch at a low cost. The production line comprises a plate conveying line, wherein the plate conveying line is sequentially provided with at least two bending areas along the conveying direction. Each bending area is sequentially provided with sets of rolling devices along the conveying direction of the plate conveying line, and each rolling device is composed of an upper roller and a lower roller. Each lower roller is composed of a transverse rod in the middle and bending bases at two ends of each transverse rod. The radius of the axial section of each bending base is gradually increased towards the end portion direction of each lower roller, and therefore a transversely-arranged truncated cone is formed. The shape of the axial section of each upper roller is consistent with that of the axial section of each lower roller. The lengths of the transverse rods of the lower rollers in the same bending area are the same. Inclined angles of side faces of bending bases of different lower rollers and axes of the lower rollers are gradually reduced along the conveying direction of the plate conveying line. The length of the transverse rod of the lower roller in one bending area is larger than the length of the transverse rod of the lower roller in the bending area behind.

Summary of the invention

The purpose of this utility model is the production line that proposes to have the shaped as frame section bar of breach, to realize low cost, to produce the shaped as frame section bar with breach continuously.

Production line with shaped as frame section bar of breach of the present utility model comprises the sheet material pipeline, and key is that described sheet material pipeline is disposed with at least two flex area along its throughput direction; Described each flex area all is aligned in sequence with the rolling equipment that many covers are made of top roll and lower roll along the throughput direction of sheet material pipeline; Described lower roll is made of the cross bar at middle part and the bending seat at cross bar two ends, and the axial cross section radius of described bending seat increases gradually towards the end direction of lower roll, thereby constitutes horizontal truncated cone-shaped; The axial cross section shape of described top roll conforms to the axial cross section shape of lower roll; The cross bar length of the lower roll in same flex area is identical, and the bending seat side of different lower rolls and the angle between the lower roll axis reduce gradually along the throughput direction of sheet material pipeline; Along the throughput direction of sheet material pipeline, the cross bar length of the lower roll in each flex area is all greater than the cross bar length of the lower roll in flex area thereafter.

The operation principle of the production line of above-mentioned section bar is as follows: sheet material is positioned over the sheet material pipeline carries, successively by each flex area, wherein:

In first flex area, sheet material can at first enter the rolling equipment of angle maximum between bending seat side and the lower roll axis, angle between first inclined-plane that the top roll of this rolling equipment and lower roll go out to be upturned with the two ends roll-in of sheet material, this moment first inclined-plane and lower roll axis is the obtuse angle; Pass through the roll-in of other rolling equipments in first flex area then, the angle between above-mentioned first inclined-plane and the lower roll axis is more and more littler, and up to meeting predetermined angle, sheet material is admitted to second flex area then.The rolling equipment of a plurality of bending angle gradients is set, and each rolling equipment power of imposing on sheet material need not too greatly like this, and can avoid taking place because bending angle of sheet material is excessive sheet material and is difficult to situation by rolling equipment.

Because the cross bar length of the lower roll in second flex area is less than the cross bar length of the lower roll in first flex area, therefore the bending seat of roll unit can make sheet material increase by two second inclined-planes between two first inclined-planes, like this, angle between first inclined-plane and the lower roll axis will further reduce, by that analogy, two or more flex area can be set as required, form the shaped as frame with breach up to sheet material.

Further, described flex area has two, is arranged in the side of bending seat of lower roll of sheet material pipeline rearmost position and the angle between the lower roll axis is the right angle along throughput direction in described two flex area.Can produce the cross section like this is the rectangular section bar with breach.

The production line of section bar of the present utility model passes through the continuous bending of sheet material, making sheet material form the cross section is the shaped as frame section bar with breach, 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 shaped as frame section bar of producing is unrestricted, and the concrete shape of shaped as frame 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 shaped as frame section bar with breach of present embodiment comprises the sheet material pipeline for delivery of sheet material 1, and the sheet material pipeline is disposed with first flex area 2 and second flex area 3 along its throughput direction; Described each flex area all is aligned in sequence with the rolling equipment that many covers are made of top roll 4 and lower roll 5 along the throughput direction of sheet material pipeline; Lower roll 5 is made of the cross bar 6 at middle part and the bending seat 7 at cross bar 6 two ends, and the axial cross section radius of bending seat 7 increases gradually towards the end direction of lower roll 5, thereby constitutes horizontal truncated cone-shaped; The axial cross section shape of top roll 4 conforms to the axial cross section shape of lower roll 5; Cross bar 6 length of the lower roll 5 in same flex area are identical, and bending seat 7 sides of different lower roll 5 and the angle between lower roll 5 axis reduce gradually along the throughput direction of sheet material pipeline; The length of the cross bar 6 of the lower roll in first flex area is greater than the length of the cross bar 6 of the lower roll in second flex area.

The operation principle of the production line of above-mentioned section bar is as follows: sheet material 1 is positioned over the sheet material pipeline carries, successively by first flex area 2 and second flex area 3, wherein:

In first flex area 2, sheet material 1 can at first enter the rolling equipment of angle maximum between bending seat 7 sides and the lower roll axis, angle α between first inclined-plane 8 that the top roll 4 of this rolling equipment and lower roll 5 go out to be upturned with the two ends roll-in of sheet material 1, this moment first inclined-plane 8 and lower roll 5 axis is the obtuse angle; Pass through the roll-in of other rolling equipments in first flex area 2 then, the angle α between above-mentioned first inclined-plane 8 and lower roll 5 axis is more and more littler, and up to meeting predetermined angle, sheet material 1 is admitted to second flex area 3 then.

Because the length of the cross bar 6 of the lower roll in second flex area 3 is less than the length of the cross bar 6 of the lower roll in first flex area 1, therefore the bending seat 7 of roll unit can make sheet material 1 increase by two second inclined-planes 9 between two first inclined-planes 8, like this, angle between the axis of first inclined-plane 8 and lower roll 5 will further reduce, and forms the shaped as frame with breach up to sheet material 1.
