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 moulds 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, the precision height that requires slide block to adjust, good stability.The slide block adjustment of using at present is to give leading screw by 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 by mechanical gear, and chain drive shows height of packing compact; Another kind is after handling through PLC Programmable Logic Controller special module by the scrambler acquired signal, to send display to and show.The indicator gauge of preceding a kind of method is mechanical, poor stability comparatively speaking, the failure rate height, visual inconvenience, and spacing up and down dependence travel switch is controlled, and pressure machine cross-beam is that fork is connected with slide block, regular being broken of superincumbent limit switch is installed, thereby causes, lower limit does not play effect, the easy stroke of crossing in slide block is adjusted, main transmission to pressing machine causes damage, in addition, and the visual mechanical type indicator gauge of operating personnel inconvenience, easy readout error data, thus apparatus overload caused.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 be broken.A kind of method in back need be installed in scrambler on the screw mandrel, and cost is higher, is easy to generate vibration when operation.
Summary of the invention
The object of the present invention is to provide the display packing of a kind of accurate rate height, demonstration regulation height of press slide that cost is low.
For achieving the above object, 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 by 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 that the slide block among the present invention is adjusted.
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, as shown in Figure 1.
In conjunction with Fig. 2,3, described slide block 50 is horizontally placed between two columns 20, the upper and lower of slide block 50 is provided with pressure machine cross-beam 10 and worktable 30 respectively, slide block 50 links to each other with height control mechanism, height control mechanism comprises motor 51, and motor 51 drives slide block 50 through gear train 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 height adjustment process to slide block 50, but not the punching course of mould.Described slide block 50 inside are provided with slide block height control mechanism, this adjusting mechanism comprises motor 51, motor 51 drives first screw mandrel 53 by belt 52 and rotates, first screw mandrel 53 is arranged in horizontal direction, its two ends respectively set firmly a worm gear 54, 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 by pressing machine fork 40 and pressure machine cross-beam 10, pressing machine fork 40 plays the effect of support slipper 50 on the one hand, on the other hand as on the slide block 50, gear train during the down stroke running.
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, regulate the distance of 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 by web member, the counterdie that matches with patrix is fixed on the worktable 30 by web member, 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 the height of slide block 50, after the height control 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.
Below in conjunction with Fig. 1,2,3 the present invention is further illustrated.
Described PLC Programmable Logic Controller 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--the A/B of the two, the i.e. pitch of first screw mandrel 53.The adjustment height H of described slide block 50 is determined with following relational expression, the altitude datum H of H=CA/B+ slide block 50
Min, described slide block 50 altitude datum H
MinIt is 610 millimeters, as shown in Figure 2, the adjustment height H of slide block 50 is meant the distance between the workplace of the lower surface of slide block 50 slide block 50 when bottom dead centre and worktable 30, bottom dead centre is the minimum point that slide block 50 moves downward, after the height of slide block 50 adjusted, the height that will show adjusted slide block 50 on the display continues to show this height in the motion process of slide block 50, adjusts 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 by being provided with in program, 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 this number of turns C is carried out computing by the PLC Programmable Logic Controller, the adjustment height of output slide block 50, and on indicator gauge, show, greatly reduce cost, the present invention can show the currency that slide block 50 is adjusted very exactly, and error is less than one millimeter.
