Description
Technical field
The present invention relates to automobile punching production apparatus field, especially a kind of display packing that shows press slide adjustment height.
Background technology
Pressing machine is a major equipment of producing automobile case spare in the automobile industry, and different dies need be adjusted the height of slide block and adorn mould again, and the slide block adjustment is the key component that influences the stamping parts quality, requires the precision of slide block adjustment high, good stability.The slide block adjustment of using at present is to give leading screw through the driven by motor belt gear, again by the rotation of leading screw through the leading screw of worm gear case transmission drive and slide block coupling part, and the distance of regulating screw mandrel and screw, thereby the adjustment of realization slide block distance.
The display packing of existing slide block adjustment height immediate shipment mould height has two kinds: a kind of is through mechanical gear, and chain drive shows height of packing compact; Another kind is after handling through PLC Programmable Logic Controller special module through the scrambler acquired signal, to send display to and show.Before a kind of indicator gauge of method be mechanical, poor stability comparatively speaking, failure rate is high; Visual inconvenience, and spacing up and down dependence travel switch controls, and pressure machine cross-beam is that fork is connected with slide block; The regular quilt of superincumbent limit switch is installed is broken, thereby cause, lower limit has played not effect; In slide block adjustment, be prone to stroke, the main transmission of pressing machine caused damage, in addition; The visual mechanical type indicator gauge of operating personnel is inconvenient, easy readout error data, thus cause apparatus overload.Cause the main cause of this phenomenon to be: 1. mechanical type digital display table, certain failure rate is arranged, operating personnel fail in time to find when finding to damage; 2. slide block is installed on the oscillating rod type pressing machine is adjusted upper and lower spacingly, on being transferred to or during lower limit, pressing machine does not just have upper and lower spacing protective effect at this moment if operation single or adjusting microinching are easy to just travel switch broken.A kind of method in back need be installed in scrambler on the screw mandrel, and cost is higher, when operation, is easy to generate vibration.
Summary of the invention
The object of the present invention is to provide the display packing of the demonstration regulation height of press slide that a kind of accurate rate is high, cost is low.
For realizing above-mentioned purpose; A kind of display packing that shows regulation height of press slide provided by the invention; The number of turns C that detector switch K rotates detected first screw mandrel exports the input end of Programmable Logic Controller PLC to, and Programmable Logic Controller PLC exports the adjustment height H of slide block after treatment to display.
The present invention utilizes switch K to detect the rotating cycle C of first screw mandrel, and through the PLC Programmable Logic Controller this number of turns C is carried out computing, the adjustment height of output slide block, and show that on display with low cost, degree of accuracy is higher.
Description of drawings
Fig. 1 is a theory diagram of the present invention;
Fig. 2,3 is respectively the minimum spacing and maximum spacing view of the slide block adjustment among the present invention.
Embodiment
A kind of display packing that shows regulation height of press slide; Detector switch K exports the number of turns C of detected first screw mandrel 53 rotations to the input end of Programmable Logic Controller PLC; Programmable Logic Controller PLC exports the adjustment height H of slide block 50 after treatment to display; Described display is the binary-coded decimal digital wash, and is as shown in Figure 1.
In conjunction with Fig. 2,3, described slide block 50 is horizontally placed between two columns 20, and the top of slide block 50 is provided with pressure machine cross-beam 10; The below is provided with worktable 30, and slide block 50 links to each other with height control mechanism, and height control mechanism comprises motor 51; Adjusting mechanism drives slide block 50 and moves up and down with respect to pressure machine cross-beam 10 and worktable 30; Here, moving up and down of slide block 50 is the height adjustment process to slide block 50, but not the punching course of mould.Described slide block 50 set inside slide block height control mechanisms, this adjusting mechanism comprises motor 51, motor 51 drives first screw mandrel 53 through belt 52 and rotates; First screw mandrel 53 is arranged in horizontal direction; Its two ends respectively set firmly a worm gear 54, and detector switch K is connected with first screw mandrel 53, two worm gears 54, second screw mandrel 55 that upwards respectively is connected; The bar length direction of second screw mandrel 55 is vertical with the bar length direction of first screw mandrel 53; Second screw mandrel 55 is connected through pressing machine fork 40 and pressure machine cross-beam 10, and pressing machine fork 40 plays the effect of support slipper 50 on the one hand, the gear train when turning round as slide block 50 upper and lower strokes on the other hand.
In conjunction with Fig. 2,3; When work; Motor 51 drives belt 52 transmissions and gives first screw mandrel 53, second screw mandrel, 55 rotations that are connected with slide block 50 parts through worm gear 54 transmission drives by first screw mandrel 53 again, the distance of regulating second screw mandrel 55 and screw; Distance between second screw mandrel 55 and the pressing machine fork 40 is changed, thereby realize adjustment slide block 50 height.Slide block 50 is connected with patrix through web member, and the counterdie that matches with patrix is fixed on the worktable 30 through web member, and slide block 50 is a reference field with respect to the workplace of worktable 30; In the actual mechanical process; Because the mold height of installing on the pressing machine is different, therefore need adjust, after the height control of slide block 50 height of slide block 50; Fixed distance between pressing machine fork 40 and the slide block 50; Just can carry out the punching press of mould then, when punching press, pressure machine cross-beam 10 drive slide blocks 50 move up and down with respect to the workplace of worktable 30.
Be further described below in conjunction with Fig. 1,2,3 couples of the present invention.
Described Programmable Logic Controller PLC is before processing, and labor measurement reaches corresponding rotation height A by the rotation number of turns B of first screw mandrel 53 that belt 52 drives, and calculates ratio one A/B of the two, the i.e. pitch of first screw mandrel 53.The adjustment height H of described slide block 50 is confirmed with following relational expression, the altitude datum H of H=CA/B+ slide block 50
Min, described slide block 50 altitude datum Hmi are 610 millimeters, and are as shown in Figure 2; The adjustment height H of slide block 50 is meant the distance between the workplace of lower surface and worktable 30 of slide block 50 slide block 50 when bottom dead centre; Bottom dead centre is the minimum point that slide block 50 moves downward, and after the height of slide block 50 is adjusted, will show the height of adjusted slide block 50 on the display; In the motion process of slide block 50, continue to show this height, adjust until next time before the height of slide block 50.
The maximal value H of the adjustment height H of described slide block 50
MaxIt is 930 millimeters; As shown in Figure 3, the adjustment height H of the slide block 50 of Programmable Logic Controller PLC output is between 610 millimeters and 930 millimeters, and is upper and lower spacing through in program, being provided with; Utilize software limit to control the adjustment stroke of slide block 50, avoid taking place the over travel stuck phenomenon.
In sum; Core of the present invention is to utilize switch K to detect the rotating cycle C of first screw mandrel 53, and through Programmable Logic Controller PLC this number of turns C is carried out computing, the adjustment height of output slide block 50; And on indicator gauge, show; Greatly reduce cost, the present invention can show the currency of slide block 50 adjustment very exactly, and error is less than one millimeter.
