Description

Dual-purpose machine is cut, rolled over to a kind of machine driving

The utility model belongs to the stress metal processing technique field.Further relate to a kind of be used for sheet metal processing cut, roll over dual-purpose machine.

At present, the dual-purpose machine of producing both at home and abroad of cutting, roll over all adopts hydraulic drive.Hydraulic drive is compared with machine driving, no doubt has many good qualities; 1) adopt hydraulicdriven pressworking equipment, body construction is simple, in light weight; 2) hydraulic drive can make equipment bring into play its rated pressure in the optional position of stroke; 3) hydraulic drive can effectively prevent apparatus overload; 4) be convenient to the automatic control of the equipment of realizing.But hydraulic drive also has many shortcomings; 1) pump, valve element are many, and fault is difficult to judge, causes the equipment reliability during operation poor, maintenance difficult; 2) in the unit interval machine to start number of times few, productivity ratio is low; 3) starting of machine is subjected to seasonal effect bigger, promptly can't work because of the hydraulic oil retrogradation Han Leng winter, and hot summer is serious because of the too rare leakage of oil of hydraulic oil.

The purpose of this utility model provides the less machine driving of a kind of tonnage ability and cuts, rolls over dual-purpose machine.It has reliability and is better than hydraulic drive, and can effectively prevent apparatus overload; Simple to operate, easy to maintenance; Machine starts number of times height, productivity ratio height in unit interval; The machine price is lower than advantages such as hydraulic drive.

The utility model comprises frame, running part, the standing part of shear, bending, the left and right sides pull bar of shear, bending, cut material knife rest and bending and put the beams in place and be connected into the motion parts of frame structure, cut bottom knife on the material, the bending punch-die, breaker, operation part and electric part.Press the couch piece to be placed on the below of bending die, running part adopts the mechanical transmission structure of underlying.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the utility model overall structure schematic diagram.

Fig. 2 is the structural representation of left view of the present utility model.

Fig. 3 is shear of the present utility model, bending, movement parts structural representation.

Fig. 4 is a breaker structural representation of the present utility model.

The utility model adopts the traditional mechanical driving part 11 of underlying.Place the motor output shaft and the small belt pulley key rigid attachment of frame 10 left ends, through belt rotation is passed to big belt pulley, big belt pulley is keyed on the left end of power transmission shaft, and pinion is keyed on the right-hand member of transmission.Pinion and gear wheel engagement.The canine tooth bye is enclosed within on the two-throw crank shaft, design one positive clutch between them.Make gear wheel drive the two-throw crank shaft rotation by operation part 9.About the lower end movable set of two identical connecting rods 8 at two crank throw places of bent axle, the upper end by bearing pin 18 with to cut material knife rest 2 hinged.The left and right sides spigot surface 17 of cutting material knife rest 2 pumps along knife rest 10, finishes and cuts the material running.Cut the material bottom knife and be fixed on and cut on the material lower slide 14, and it is fixing to cut material lower slide about 14 and frame 10.Material pressing device 6 flexibly connects with cutting material knife rest 2, presses toward plate before cutting by its spring force.Behind the shear backgauge 13 with cut material knife rest 2 rear portions and flexibly connect.Retainer 15 is with to cut material lower slide 14 fixing before the shear.

The punch 5 that the plate bending is used is fixed on bending 3 belows of putting the beams in place, and bending groove 4 is fixed on bending underbeam 1 top by groove seat 20, and the two ends, the left and right sides of bending underbeam 1 are extremely solid with frame 10.Bending upper beam 3 also need pump.Backgauge 12 connects with the rear portion of bending groove seat 20 after the bending.Electric part 7 and actuating element 9 are fixed on the frame 10.

With reference to Fig. 3, two pull bars 16 of the present utility model are cut material knife rest 2, putting the beams in place with the bending of fixing bending punch 53 is coupled to a frame structure.This framework is under the drive of left and right sides connecting rod 8, and is reciprocating together up and down, thereby realizes cutting, rolling over two kinds of different processing technologys.Promptly finish bending, finish in the machine Lower Half and cut material at the machine first half.

Be fixed on the bending underbeam 1 with reference to Fig. 4, die socket 20, bending die 4 directly is placed in the groove of die socket 20 by breaker 19.

Breaker 19 is the cuboid symmetry parts that adopt cast iron to make.Its top has one to be the groove of symmetry with the center line, and the bottom has one to be the boss of symmetry with the center line, and the boss height is H.Depth of groove is slightly littler than H in addition, and recess width is bigger slightly than boss width.When overload, two identical rectangular faces sink simultaneously about breaker 19 sections, thereby make bending die 4 relative die sockets 20 move down the H distance, so the bending punch can be avoided the machine overload in bottom dead centre H scope.

The utility model is durable, the life-span is long, and is simple to operate, and it is easy, easy to maintenance that fault is judged, the productivity ratio height, and low price, and can effectively prevent overload.
