Description

Roller arc machine

Technical field

The utility model relates to architectural shape bending apparatus technical field.

Background technology

Three traditional roller roller arc machines are suitable for sheet material roller arc, be easily out of shape even cannot process for U-shaped shape extrusion.Other processing equipments are as arcing machine, and mechanical processing technique is complicated, and mechanical purchase cost is high.

The roller arc machine of tradition special processing section bar, the right-angle side spacing for processed section bar installs corresponding running roller, and two right-angle side spacing of the cannelure on running roller and section bar match.When processing the section bar of plurality of specifications, need repeatedly to change running roller or just can complete at multiple stage roller arc hands-operation, this just causes the efficiency of processing plurality of specifications section bar lower, and cost raises.

Utility model content

Technical problem to be solved in the utility model, it is the technical deficiency for above-mentioned existence, a kind of roller arc machine is provided, can by the section bar of the adaptive different size of the fetch bit ring of dismounting diverse location, a roller arc machine achieves the roller arc of the section bar of plurality of specifications is processed, improve operating efficiency, save equipment cost.

The technical solution adopted in the utility model is: provide a kind of roller arc machine, comprises support, two driven running rollers be arranged in parallel of horizontal direction, and active roll that spacing equal parallel with two driven running rollers; The two ends of two driven running rollers are all connected with rack shaft; The two ends of active roll are connected with the slide block rotating shaft at support two ends respectively; The slide rail that slide block and support vertical direction are arranged is slidably matched; Slide block is provided with and penetrates support and the elevating lever be threaded with support at vertical direction; Active roll side and each driven voller wheel side even in the longitudinal direction near being arranged with fetch bit ring; Fetch bit ring is by grafting and form by two hemizonids that bolt is fixing.

Further optimization the technical program, the slide rail outward flange length direction that each slide block of roller arc machine is corresponding is provided with markings.

Further optimization the technical program, active roll and each driven running roller inside of roller arc machine are radial cavity.

Further optimization the technical program, the active roll side of roller arc machine and the side of each driven running roller are all covered with rubber layer.

The beneficial effects of the utility model are: 1, by the section bar of the adaptive different size of the fetch bit ring of dismounting diverse location, a roller arc machine can achieve and process the roller arc of the section bar of plurality of specifications, improve operating efficiency, saved equipment cost.2, the position of two slide blocks can be adjusted on sustained height by markings, is convenient to operating personnel fast by active roll leveling.3, the inside of active roll and driven running roller is radial cavity, both ensure that the intensity of roll-in, turn reduces the weight of Whole Equipment, reduces equipment cost.4, rubber layer increases the frictional force of fetch bit ring and active roll and driven running roller, can prevent in the operation of roller arc because vibrations cause fetch bit ring to come off.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, roller arc machine, comprises support 1, two driven running rollers 2 be arranged in parallel of horizontal direction, and active roll 3 that spacing equal parallel with two driven running rollers 2; The two ends of two driven running rollers 2 are all connected with support 1 rotating shaft; The two ends of active roll 3 are connected with slide block 4 rotating shaft at support 1 two ends respectively; The slide rail 5 that slide block 4 and support 1 vertical direction are arranged is slidably matched; Slide block 4 is provided with and penetrates support 1 and the elevating lever 6 be threaded with support 1 at vertical direction; Active roll 3 side and each driven running roller 2 side is even in the longitudinal direction has fetch bit ring 7 near arrangement (namely evenly distributed between fetch bit ring 7 and contact); Fetch bit ring 7 is by grafting and form by two hemizonids 8 that bolt is fixing; The slide rail 5 outward flange length direction of each slide block 4 correspondence is provided with markings 9; Active roll 3 and each driven running roller 2 inside are radial cavity 10; The side of active roll 3 side and each driven running roller 2 is all covered with rubber layer 11.

In the utility model, (driving mechanism is generally directly and the rubber drive wheels of driven running roller 3 contacts side surfaces for active roll 3 and driving mechanism, consistent with the type of drive of existing roller arc machine) link, and driven running roller 2 moves and moves along with pressurized sheet material or section bar.

The utility model is consistent with existing three-roller type roller arc machine to the mode of operation of sheet material roll bending, is namely first put into by sheet material between three running rollers, in the process of active roll 3 rolling, then gradually regulates the height of active roll 3, until reach the radian of regulation.

When processing section bar, for the right-angle side spacing of this kind of section bar, dismantle lower two fetch bit rings 7, the spacing between two the annular dead zones stayed after making dismounting and the right-angle side spacing of section bar suitable, during roller arc, two right-angle sides of section bar snap in two annular dead zones respectively.The utility model can also dismantle lower multipair fetch bit ring 7 simultaneously, forms the annular dead zone pair of multiple corresponding different size, realizes the roller arc operation to multiple section bar.

As shown in Figure 2, when pulling down fetch bit ring 7, bolt 12 is unclasped, be then separated the hemizonid 8 of two grafting.
