Specific embodiment
Specific embodiment of the invention is made a detailed explanation below in conjunction with the accompanying drawings.
The pre- machine drawing of a kind of automatic die as depicted in figs. 1 and 2, including frame, prestretching hydraulic cylinder 12, the first sliding block 6, cunning
Mould 4, prestretching driving gear 8, prestretching driving shaft 15, the second sliding block 11, first support under block 5, prestretching driven gear 7, die
10th, die hydraulic cylinder 9 and servomotor 17, the prestretching hydraulic cylinder 12 are fixed on the outer end of the side plate 1 of frame, the take-up housing
The side of 5 upper surfaces of base plate 3 for being fixed on frame, and take-up housing is respectively arranged at two ends with the first spacing proximity switch 51 and second
Spacing proximity switch 52, first sliding block 6 is slidably arranged on take-up housing 5, and the first sliding block 6 one end and prestretching hydraulic cylinder
12 are connected, and the upper surface of the other end of first sliding block 6 is fixed with driven shaft, the prestretching driven gear 7 be set in from
On moving axis, the prestretching driving shaft 15 runs through the opposite side of the base plate 3 of frame by axle bed, and the prestretching driving gear 8 is fixed
In the upper end of prestretching driving shaft 15, and on axle bed counting proximity switch 81, institute are further fixed on positioned at the lower section of prestretching driving gear 8
Mould 4 is fixed on the base plate 3 of the frame between take-up housing 5 and prestretching driving shaft 15 under stating die, and the side of mould 4 is consolidated under die
Surely there is zeroing proximity switch 41, second sliding block 11 is arranged on the base plate 3 of frame by slide, and the second sliding block 11
The opposite side of mould 4 under die, the glide direction of the second sliding block 11 is parallel with the glide direction of the first sliding block 6, and described
One support 10 is arranged on the upper end of the second sliding block 11, and the glide direction of first support 10 and the second sliding block 11 by slide
Glide direction is perpendicular, and the die hydraulic cylinder 9 is fixed in first support 10, and between the upper and lower every setting on the side wall of first support 10
It is equipped with the 3rd spacing proximity switch 91 and the 4th spacing proximity switch 92, the frame between second sliding block 11 and take-up housing 5
Base plate 3 on be further fixed on slide calliper rule 13, and the first sliding shoe 6 is towards instruction block 14 is fixed with the side wall of slide calliper rule 13, described to watch
The bottom that motor 17 is fixed on the base plate 3 of frame by second support 16, and servomotor 17 are taken by conveyer belt and prestretching master
The lower end of moving axis 15 is connected.The frame is additionally provided with the bottom of transparent safety door 1 and frame away from the side of the second sliding block 11
Plate 3 is provided with safety door proximity switch 18.
The centre-to-centre spacing median value range of general chain is substantially between 210-245mm.Prestretching sprocket outside diameter is general in 80-
Between 100mm.So result in distance only 100-140mm or so between two prestretching sprocket wheels.Such small spacing is in chain riveting
Need to arrange that pre-tensioning device causes very big challenge to chain to avoid chain tooth from jumping the engagement such as tooth exception during head.While chain
Pre-tensioning 2KN, die power 23KN, pretension 110KN, the pretension range of application of wide cut needs accurately frequent switching, together
Sample is a no small challenge.Therefore take accurate Proportional Valve-controlled to meet each hydraulic system of the above-mentioned requirements pre- machine drawing of automatic die
System processed, for safety and operational comfort from the aspect of, the whole process layout of the automatic pre- machine drawing of die uses horizontal layout
Scheme.
The method that die, prestretching and center distance measurement are carried out to chain using the automatic pre- machine drawing of die includes following step
Suddenly：
1) manually opened safety door switch, transparent safety door is opened, and chain is enclosed within two sprocket wheels, and closed safe door is opened
Button is closed, safety door is closed, and automatic flow is opened；
2) prestretching hydraulic cylinder applies the pulling force of 1-2KN to the first sliding block, chain is gently tensioned, while servomotor revolves at a slow speed
Turn so that the bearing pin of chain is detected by zeroing proximity switch；
3) after the initial position of chain determines, die Hydraulic Cylinder die block moves down beginning die process, and die is completed
Moved on die Driven by Hydraulic Cylinder die block afterwards and resetted, while servomotor starts normal rotation send chain, be rotated in place rear servo electricity
Machine stops, and after the die block of upper shifting is detected by the 3rd spacing proximity switch, hydraulic pressure die cylinder drives die block to move down again
Die is carried out, is then moved on die block, servomotor starts feeding next time, then die again, until whole chain riveting is complete, die liquid
Cylinder pressure last time is risen at the 4th spacing proximity switch, servomotor stalling；
4）After 0.5 second, prestretching hydraulic cylinder applies the pulling force of 110KN to the first sliding block, and prestretching hydraulic cylinder is unloaded after being kept for 40 seconds
Lotus causes the first sliding block homing, and servomotor stops at a high speed after rotation causes whole chain rotation a quarter circle, pre- after 0.5 second
Hydraulic cylinder is drawn to apply the pulling force of 110KN to the first sliding block again, prestretching hydraulic cylinder off-load causes that the first sliding block is returned after being kept for 40 seconds
Restore position；
5）Prestretching hydraulic cylinder applies the pulling force of 2KN to the first sliding block again, and now display is shown on the first sliding block in real time
Position of the instruction block on slide calliper rule, i.e. chain center distance numerical value, the off-load of prestretching hydraulic cylinder causes that the first sliding block is replied after 1.5 seconds
It is in situ；
6）Safety door is opened, chain is taken out by hand, be placed again into new chain to be processed, close protective door, opened new
Flow.
