When punch press moves, power is transferred on the camshaft 59 of transmission case from output shaft via intermediate chain wheel 41, drive camshaft 59 rotations, and cam 58 is linked together by tooth and camshaft 59, thereby and then camshaft 59 rotates together, and drive push rods 60 by camshaft bearing 61 and in the locating hole of upper bracket 62 and lower carriage 621, move up and down, chain bar 63 links together by pin and push rod 60 and follows push rod 60 to move up and down, then with moving block 64 with on the chain bar 63, following motion is transformed into the motion that rotates back and forth of turning cylinder 57, thereby has realized the motion that manipulator clamps and unclamps.
Punch press power is delivered on the main transmission box sprocket wheel 421 by the chain transmission, thereby the disc cam 58 of drive material folding and the cylindrical cam 45 of feeding rotatablely move.When punch press during at top dead-centre, manipulator is in clamped condition, punch press down moves from top dead-centre, the disc cam 58 of material folding and the cylindrical cam 44 of feeding be and then rotation also, when in mold and punching head enters the per pass process product, also accurately locating, the disc cam 58 jack-up follower levers of material folding also are rotated counterclockwise by the turning cylinder 57 in the moving manipulator 9 of the rider on the bar, and the shift fork 54 on this turning cylinder 57 is stirred in the manipulator 9 second slide block 50 and shunk back and send out product.The punch press continuation is down moved, and when arriving certain position, the cylindrical cam 45 of feeding drives follower levers, and the whole manipulator of fixed bar 48 drives of driving machinery hand 9 moves to last operation preparation clamping left.When punch press when bottom dead centre up moves to a certain position, product has exceeded the mould plane, the disc cam 58 of material folding drives shift forks 54 and turns clockwise, the clamping product that move forward of second slide block 50 in the manipulator 9.Punch press continues up motion, and material returning system is all backed off every process product from drift after, the fixed bar 48 that the cylindrical cam 45 of feeding drives manipulator 9 moves right, and product is delivered to back one operation.Circulation has just realized that manipulator changes material automatically and stretches thus.
Coiled strip enters mould first operation through pneumatic feed device 10, automatically change subsequent processing over to by manipulator 9 behind the punch press one stroke, in drawing process, product in the die is ejected die by cylinder in the liftout system 5 and ejection block, then along with drift is up, material returning sleeve 32 in the material returning system 4 is backed off product from drift, after finishing each preface successively and stretching and cut edge, manipulator 9 is put into output on the conveyer belt 11 with product.
In sum, because of between stretching die and material returning sleeve 32, being provided with manipulator 9, make it can adopt full-automatic process to replace the operation of existing most of artificial operation, thereby reach the production efficiency that improves entire product, also can improve simultaneously the security of personnel operation, the processing cost of reduction product, improve the quality of processed product.Because of being provided with detection system between each operation and on the manipulator, guaranteed that equipment and mold can safe and reliable operation in the full automatic processing.Because of being provided with manipulator 9 and pneumatic feed appliance 10, make it can simplify the technological process of processing again, finish feeding, stretching between each operation automatically, of the present invention have processing simply.
In addition, multistation punch device of the present invention has following advantages: 1, the multistation punch press has high-performance, the high accuracy that is complementary with mechanical system; 2,, make it have high accuracy, high rigidity, long-life, good hear resistance, constant product quality because of adopting high performance wolfram steel material to make mould; 3,, can guarantee that constant product quality, mould work safely and reliably because of adopting accurate fairlead mechanism; 4, have high efficiency, high-quality; 5, adopt the pneumatic liftout system and the material returning system of cam, guarantee that the material returned accurately, reliably, has guaranteed producing automatically continuously of production line; 6, in automatic feeding system, increased brakes, avoid of the influence of moving parts inertia to transmission mechanism, guarantee the accuracy of transmission.
Please refer to Figure 20 to shown in Figure 22, the described manipulator difference among the manipulator described in second kind of embodiment of the present invention and the first kind of embodiment: described manipulator 9 comprises first base 70, be installed on the seat of honour 72 on first base, 70 tops, be installed in the guide groove at the seat of honour 72 and the 3rd slide block 76 that slides before and after carrying out, be installed on the loam cake 71 that is used on the seat of honour 72 press toward the 3rd slide block 76, be installed on the stationary pipes 73 of the seat of honour 72 and first base, 70 inside, be installed on first turning cylinder 74 of stationary pipes 73 inside, be installed on the interior copper billet 75 of square hole of the 3rd slide block 76, be fixed in the fixture block 77 of the 3rd slide block 76 1 ends and rely on himself screw thread to be fixed on first turning cylinder 74 and insert fork 78 in the copper billet 75.But be to drive its first turning cylinder, 74 reciprocal rotations by mechanical grip mechanism to realize degree of tightness and unclamp equally.
Described manipulator 9 is installed on the described punch device, can reach first kind of technique effect described in the enforcement equally.
