Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but As long as it is all protected in the right of the utility model by Patent Law.
As shown in Figure 1, a kind of sheet punch, the feeding device 2 including rack 1 and positioned at 1 side of rack, rack 1 are wrapped The workbench 11 for placing thin metallic plate is included, is slided in rack 1 and is provided with staking punch 12, be additionally provided with and be used in rack 1 The driving mechanism 3 that driving staking punch 12 moves back and forth.Feeding device 2 includes pedestal 21, is slideably positioned on pedestal 21 Slide unit 22, the glide direction of slide unit 22 is perpendicular to pedestal 21 and the line direction of rack 1.
Staking punch 12 is located at the surface of workbench 11, and the glide direction of staking punch 12 is perpendicular to the table top of workbench 11. Staking punch 12 is provided with mold 121 close to one end of workbench 11, and in the present embodiment, mold 121 on thin plate for stamping out Disk product.It is opened up respectively there are two rectangular discharge port 111 positioned at the both sides of stamping position on workbench 11, two discharge ports 111 line direction is identical with the glide direction of slide unit 22.Pressure rack 13 is provided in rack 1, pressure rack 13 is located at 12 He of staking punch Between pedestal 21, and it is suspended on the table top of workbench 11.Pressure rack 13 is overall U-shaped, and the bottom surface of pressure rack 13 is lower pressure surface 131, under The distance between pressure surface 131 and workbench 11 are equal to gauge of sheet, lower pressure surface 131 be used for the upper surface of thin plate offset so as to Thin plate is limited on workbench 11.
As shown in Fig. 2, driving mechanism 3 includes being located at the bent axle 31 of 12 top of staking punch, the main motor being fixed in rack 1 32.Bent axle 31 includes main shaft 311 and is eccentric in the eccentric shaft 312 of main shaft 311, and main shaft 311 is rotatably dispose in rack 1 by bearing On, the output shaft of main motor 32 is connected to one end of main shaft 311, and the other end of main shaft 311 is fixed with flywheel 33, the axis of flywheel 33 Line is overlapped with the axis of main shaft 311.Connecting rod 34 is provided between bent axle 31 and staking punch 12, one end of connecting rod 34 is articulated with bias Axis 312, the other end of connecting rod 34 are articulated with staking punch 12.During work, 32 driving spindle 311 of main motor rotates, then is eccentric in master The eccentric shaft 312 of axis 311 generates circular motion, and then one end of connecting rod 34 is driven to move in a circle, the other end of connecting rod 34 by It first 12 limits, then can only move up and down in being stamped, so as to form typical crank and rocker mechanism, staking punch 12 is made to generate company Continuous reciprocating motion.Flywheel 33 is also rotated with main shaft 311, and flywheel 33 substantially increases the rotator inertia of bent axle 31, improves Stamping press, it is ensured that thin plate can reliably be cut off during punching press.
As shown in Figure 1, rotation is provided with for the drive roll 221 of grabbing thin plates and driven voller 222, drive roll on slide unit 22 221 and driven voller 222 each parallel to slide unit 22 glide direction.Gap length between drive roll 221 and driven voller 222 is smaller In gauge of sheet, then after penetrating thin plate between drive roll 221 and driven voller 222, drive roll 221 will be thin with driven voller 222 Board clamping, there are larger stiction between drive roll 221 and thin plate.The first servo motor 23 is provided on slide unit 22, The output terminal of first servo motor 23 is connected to one end of drive roll 221, then when the first servo motor 23 works, the first servo electricity Machine 23 drives drive roll 221 to rotate, and drive roll 221 drives thin plate to be moved to 12 direction of staking punch by stiction.
Also rotation is provided with two help rolls 223 on slide unit 22, and two help rolls 223 are each parallel to drive roll 221, two Gap length between help roll 223 is slightly less than gauge of sheet.Two help rolls 223 are used to assist grabbing thin plates, it is ensured that thin Plate is entered with correct angle between drive roll 221 and driven voller 222.On slide unit 22 two gears are respectively arranged with perpendicular to table top Plate 24, two baffles 24 are located at the axial both sides of drive roll 221, driven voller 222 and two help rolls 223, two baffles respectively The distance between 24 is of same size with thin plate, and two baffles 24 are for preventing thin plate from generating lateral movement on slide unit 22.
Slide unit 22 is to realize what is be slidably connected by way of sliding block and sliding rail cooperation with pedestal 21.Rotation is set on pedestal 21 Screw 211 is equipped with, the axial direction of screw 211 is parallel with the glide direction of slide unit 22.It opens position on slide unit 22 corresponding to screw 211 Equipped with threaded hole 224, slide unit 22 is threadedly coupled by threaded hole 224 with screw 211.The second servo motor is provided on pedestal 21 212, the output terminal of the second servo motor 212 is connected to one end of screw 211, then 211 turns of screw of the second servo motor 212 driving When dynamic, slide unit 22 can generate slip due to the threaded connection of screw 211 and threaded hole 224 acts on.
During work, main motor 32 is opened, main motor 32 drives the reciprocating motion of the generation upper and lower directions of staking punch 12, mold 121 switching offsets and discrete state on workbench 11 repeatedly.The sheet metal raw material of long sheet is filled in two from width one end Between a help roll 223, and the end for pullling thin plate is filled between drive roll 221 and driven voller 222.Start the first servo motor 23 and second servo motor 212, thin plate is under the drive roll 221 of rotation and the clamping action of driven voller 222 to 12 side of staking punch To movement, the second servo motor 212 drives slide unit 22 to generate lateral movement.
The control circuit of the first servo motor 23 and the second servo motor 212 is programmed in advance, makes the first servo motor 23 A bit of time T2 is run after interval time T1, completes the automatic feed of thin plate length direction;It is spaced the second servo motor 212 Run a bit of time T4 after time T3, T3 moves back and forth that the primary time is identical with staking punch 12, and T1 is the multiple of T3, when the After the duration of runs of two servo motors 212 in one direction reaches T1, invert the second servo motor 212 and recycle above-mentioned step Suddenly, the automatic feed in web width direction is completed.Circulation action as described above can then realize the S-shaped trend of thin plate by mold 121 strike out multiple disk products, and the length direction and width direction of thin plate can be by 121 punching presses of mold, as shown in Figure 3.This Control program can realize that therefore not to repeat here with PLC.The value of T1, T2 and T4 can advanced optimize, and reduce on thin plate rush as possible The distance between mouth is pressed, the area of thin plate is enable more effectively to be utilized, so as to reduce clout.This punching course is without manually grasping Make, production efficiency is high.
Disk product after punching press follows thin plate to generate transverse movement, and disk product pushes one discharge port 111 to by thin plate, And the table top of workbench 11 is fallen down from discharge port 111, complete automatic blanking.
The above is only the exemplary embodiment of the utility model, the protection model rather than limited the present invention It encloses, the scope of protection of the utility model is determined by appended claim.
