The specific embodiment
Referring to Fig. 1, the processing unit (plant) of the aluminium sliding sleeving hole that the utility model embodiment provides comprises decompressor, indexing means and the power set that are connected respectively with frame and is used for the fitting device 20 of clamping, positioning workpieces aluminium sliding sleeve.Wherein, power set comprise the strong power set of pneumatic flesh, the lead 10 that it comprises two blocks of up and down plates (23 with are connected), air accumulator 16, the briquetting 11 that is connected with lower portable plate 25, be connected simultaneously with two portable plates and be connected entablature 24 the two pneumatic flesh that are connected simultaneously with frame with upper mobile board 23 and be good for 9 and spring 21; Air accumulator 16 is connected with pneumatic flesh strong 9 by air inlet pipe, and the radical of pneumatic muscle 9 can be 6.Wherein, decompressor comprises die lifter, drift 4, die shoe 3 and the dividing spindle 5 that is connected with punch die base 1 respectively; Die lifter comprises molding cylinder 12 and connecting plate 22, and connecting plate 22 is connected with punch die base 1 by molding cylinder 12, and drift 4 is connected with connecting plate 22, and when punching press aluminium sliding sleeving hole, connecting plate 22 contacts with briquetting 11, and drift 4 contacts with workpiece aluminium sliding sleeve 2; A modular form of molding cylinder 12 pulling connecting plates 22 has enough molding power for the frictional force that overcomes 4 of punching press aluminium sliding sleeve workpiece 2 and drifts; Die shoe 3 includes stamping cavity die 15, the hole interference fit of processing on stamping cavity die 15 and die shoe 3 faces of cylinder, simultaneously die shoe 3 and aluminium sliding sleeve 2 matched in clearance; The spindle nose of dividing spindle 5 is connected with key with bolt with the frock clamp of positioning tool 20, and the frock clamp 20 of positioning tool and workpiece aluminium sliding sleeve 2 are connected with bolt.Wherein, indexing means comprises the mechanical pin positioner, and it comprises calibration cylinder 13, calibration shift fork joint 14, calibration shift fork 6 and the check parts that connect successively; Calibration cylinder 13 is connected with gas circuit, and calibration shift fork 6 is connected with dividing spindle 5 by the check parts, and wherein, the check parts can be check bearings 19, and calibration shift fork 6 is connected with key with check bearing 19 outer rings, and check bearing 19 inner rings and dividing spindle 5 are connected with key.
Wherein, die shoe 3 also has platform shape, and this morpheme is in the oblique below of stamping cavity die 15 present positions.This structure adopts excision die shoe 3 bottom semi-circular structure, can reduce the contact area of die shoe 3 and workpiece aluminium sliding sleeve 2, reduces contact friction force, is beneficial to simultaneously the punching press chip removal.
Wherein, indexing means also comprises the rigidity bolt positioning device, it comprises location inserting column cylinder 17, the location inserting column 8 and the index dial 7 that is connected with dividing spindle 5 that connects successively, wherein, location inserting column cylinder 17 is connected with gas circuit, index dial 7 is connected with the flat key form with dividing spindle 5, and when the rigidity bolt positioning device was located, location inserting column 8 inserted index dial 7.
Below be the operation principle of the processing unit (plant) of the aluminium sliding sleeving hole that provides of the utility model embodiment:
