Description
Technical field
The invention belongs to crane span structure manufacturing equipment, especially relate to the processing method of a kind of bridge cover plate hemmer and bridge cover plate.
Background technology
Cable testing bridge is a kind of general designation of rigid structure of support cable, protection cable, specification cable, and system comprises straight-through, horizontal curved and leads to class, vertical curved logical class.Curved logical class (horizontal curved comprising various angle leads to class, horizontal threeway, horizontal four-way etc.) is a kind of connecting-type crane span structure of protection turning of cable; cable must be circular arc when turning and require certain arc radius; in order to be consistent shape with the cable at turning; play best protective effect, it is best selection that curved logical class is done in the arc-shaped.But circular arc is curved leads to has certain difficulty man-hour adding, even if processed, interchangeability is also poor, and especially circular arc cover plate is all the more so.
Under such circumstances, curved logical class crane span structure is considered to be processed into sector when designing, although shape when turning with cable testing bridge not too conforms to, also can meet use.Consider current technical difficulty and processing cost, the professional standard of cable testing bridge also allows curved leading to be processed into sector.
Along with the development of science and technology and the raising of people's aesthetic conceptions; also more and more higher to the processing of curved logical class crane span structure; increasing high-end engineering focuses on the protection to cable more, and require that curved logical class must be circular arc, the high efficiency processing that curved bend leads to class cover plate is more and more brought into schedule.
The curved logical necessary supporting circular arc cover plate of circular arc, but the processing of circular arc cover plate two side flanging is a technical barrier all the time.In order to ensure profile and the size of product, adopt following two kinds of processing modes at present:
1. parts processing: adopt tower punching to process the upper plane of circular arc cover plate, the lower bending edges of two sides adopts the mode of welding to be fixed on arc in plane.Owing to being split welding, profile is ugly and there is welding interior stress, yielding.
2. overall processing: drop into a large amount of large molds, adopt different moulds once compressing according to different cover plate specifications, workpiece configurations is attractive in appearance, and precision is high.Shortcoming: different specifications adopts different moulds, cost drops into huge, and the process-cycle is long.

The processing mode of roller pressure type, effectively can improve working (machining) efficiency, cut down finished cost, and the cover plate solving welding production easily produces the problems such as distortion; Equipment volume is little, is shaped fast, can processes the curved cover plate of arbitrary dimension, not limit by size completely.
Further, described fixed mechanism is provided with stopping means, and the lower end of this stopping means is between active roll and driven running roller.
Stopping means is for ensureing product flange height uniformity.
Further, scratch diskette is provided with between described workbench and described roller press mechanism.
Add scratch diskette, have certain distance between product to be processed and workbench, handled easily.
Further, described fixed mechanism is provided with the adjustment structure of the spacing regulating driving shaft and driven shaft.
The processing of the thick material of different material can be met, improve the application efficiency of equipment.
Further, described driving shaft and driven shaft are fixed on described fixed mechanism by bearing.
Installing bearing can extend the service life of roller press mechanism, enhances productivity.
Another object of the present invention is the processing method providing a kind of bridge cover plate, comprises the steps:
(1) the default flange section of termination making that one section of lower flanged edge making is preset in cover plate, is first turned up in advance in the termination of cover plate;
(2), start bridge cover plate hemmer according to claim 2, cover plate is preset the guide plate that flange section inserts equipment;
(3), preset after flange section guides entered two running rollers by guide plate, two running rollers clamping cover plate pre-flange, along with the subtend of two running rollers is rotated, guide arc-plane and dig fast along curved line, reach interior outer arc side flanging forming.
Further, in the middle of two running rollers of subtend rotation, stopping means is provided with.
Bridge cover plate processing method provided by the invention, completely not by the restriction of size, within several seconds, kind can process a product, effectively improves working (machining) efficiency.The production of the product of the size range 10 ~ 15mm of the lower flange of arc-shaped side can be met, reduce processing cost.
