The specific embodiment
Below in conjunction with Figure of description and embodiment, the present invention is further described.
In conjunction with this steel-aluminum conductor rail forming process of special-purpose process equipment, comprise the steps:
1. the positioning and locking process of workpiece:
Three place's uplifting devices at bench board middle part stretch out work top, section is to the aluminium section bar 21 of I shape and the c-shaped stainless steel band 22 of section by being manually lifted between the registration device end to end 3 on bench board, the upper surface of aluminium section bar is provided with the link slot 211 relative with the end of stainless steel band, and the two ends of stainless steel band 22 are plugged in this link slot 211.
Adjust afterbody registration device 3 positions, with locking wrench 31 lockings, both are clamped and are formed in conjunction with forming workpiece body 2.
Shake jacking mechanism handwheel 32 again, workpiece body is clamped between head-tail registration device 3, uplifting device falls, and it is upper that whole workpiece body 2 drops on 6 of bench board, and mobile beginning on 6 of bench board progressively starts workpiece body to carry out roll-in operation with main frame.
2. the roll-in process of workpiece:
Main frame enters after workpiece, and first roll process is started working, and by an oil cylinder, driving the upper surface of 41 pairs of workpiece bodies of the first running roller is the downward roll-in of upper side of stainless steel band; Main frame is then gone ahead, and as shown in Figure 2, second roll process starts, and by the group oil cylinder being located at table top angled (angle is adjustable), drives the lateral surface of the connecting bridge of 42 pairs of aluminium section bars of side pressure running roller and stainless steel band to carry out roll-in; As described in Figure 3, then the 3rd roll process starts, what by a pair of oil cylinder, driven is distributed in above workpiece body and longitudinally nine pairs of pony roll wheels, the 43 downward roll-ins of mutual dislocation, meanwhile, below workpiece flank, be longitudinally also provided with the little running roller of nine pairs of little running rollers above workpiece body relative, to the roll-in facing up of the upper inside of the aluminium section bar of I shape, can make aluminum component and the comprehensive laminating of corrosion-resistant steel bent plate; And then start the 4th roll process, be located at the another group oil cylinder of table top angled (angle is adjustable) and drive the lateral surface of the connecting bridge of 42 pairs of aluminium section bars of side pressure running roller and stainless steel band to carry out roll-in, laminating is more closely put in place; Main frame is gone to workpiece afterbody from workpiece head like this, completes preforming.
3. the riveted fitting process of workpiece:
Preforming completes the commutation of aft engine direction of travel, and then oppositely walking realizes riveted action.Stainless steel band is provided with rivet hole 221 and impresses one to one 221 with rivet hole, riveted action is driven by a group oil cylinder, be step-type, thereby send operation signal by the video sensor 51 searching impression ,Bing Xiang riveting job mechanisms that are located at riveted actuating member 5 two ends, workpiece body carried out to riveting job.Approach switch (not shown in FIG.) is housed respectively on riveted actuating member 5, detects oil cylinder and whether move, oil cylinder is depressed, machine work, and approach switch give a signal when oil cylinder lifts, machine stops riveted action.Equipment automatically detects the position of finishing the work to be stopped after compound, and returns to start bit.Finally complete the riveting job of workpiece body after preforming is riveted on stainless steel band in link slot, to form steel-aluminum conductor rail.
Manually unclamp afterbody workpiece clamping frock and hang the lower compound workpiece completing, a workflow completes.
