Description of drawings

Fig. 1 is a structure principle chart of the present invention.

Fig. 2 is a work schematic diagram of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figure 1, be provided with the travelling car 1 of roller bottom the present invention includes, can push on the ground, travelling car 1 front is connected with rotation platform 3 by swiveling gear 2, swiveling gear 2 drives by motor 17, can make rotation platform 3 do the comprehensive revolution of 360 degree; Afterbody is provided with hydraulic control system 4 in the front of rotation platform 3, is used for each hydraulic cylinder is done hydraulic control and driving; Positive middle part at rotation platform 3 is provided with column 7, is articulated with a fulcrum 8-2 of trident linking arm 8 on the top of column 7, and the fulcrum 8-1 of linking arm 8 articulates with the piston rod that falls hydraulic cylinder 6 of bowing, and the cylinder body that falls hydraulic cylinder 6 of bowing is articulated on the rotation platform 3; Another fulcrum 8-3 of linking arm 8 is articulated with guide cylinder 12 by last connecting rod 11, guide cylinder 12 is articulated on the column 7 top pivot 8-1 by lower link 9 simultaneously, and so linking arm 8, guide cylinder 12 have promptly been formed parallel-crank mechanism with last connecting rod 11, lower link 9; The cylinder body of hydraulic cylinder 10 of steeving is articulated on the column 7, and piston rod is articulated on the guide cylinder 12.Guide cylinder 12 is provided with the gear (not shown) that the telescopic electric machine drives, and is meshed with the tooth bar 16 of cantilever 5 lateral surfaces, stretches out forward or backward movement backward by gear rotating drive cantilever 5.Cantilever 5 is a hollow-core construction, and front end stretches out flip-arm 13, and flip-arm 13 can be done upset with its central axis by the cantilever 5 inner upset hydraulic cylinder control (not shown) that are provided with; Flip-arm 13 also is a hollow-core construction, and the middle part is provided with clamp hydraulic cylinder (not shown), and the piston rod of clamp hydraulic cylinder connects left fixture block 14, and right fixture block 15 is fixed on flip-arm 13 front ends, matches with the left fixture block 14 of activity to realize clamping and loosens function.

Real work as shown in Figure 2, pipe fitting raw material 20-1 concentrates and is placed on raw material district 21, processing district 22 is provided with hydraulic pressure cold shaping machine and shaping dies, tee pipe fitting finished product 20-2 after the processing concentrates and is placed on finished product district 23, three zones become " product " font to arrange, be positioned on the same circumference,, loading and unloading manipulator of the present invention be placed between raw material district 21 and the finished product district 23 by pushing the roller of travelling car 1 bottom.

The first step, the gripping raw material: cantilever 5 is positioned at 21 tops, raw material district during initial state, and the piston rod of clamp hydraulic cylinder stretches out action, and left fixture block 14 travels forward, and cooperates right fixture block 15 to clamp pipe fitting raw material 20-1.

In second step, material loading: motor 17 drives swiveling gear 2, makes rotation platform 3 drive cantilever 5 and is rotated counterclockwise 90 degree as shown in Figure 2, raw material is delivered to the shaping dies top of the hydraulic pressure cold shaping machine of processing district 22; The piston rod that falls hydraulic cylinder 6 of bowing this moment is done and is stretched out action, utilize parallelogram sturcutre stable make guide cylinder 12 drive cantilevers 5 to do to bow and fall, the piston rod of the hydraulic cylinder 10 of steeving this moment cooperates retraction; The piston rod of clamp hydraulic cylinder shrank after raw material put in place, and left fixture block 14 loosens backward.

In the 3rd step, material loading is return: the piston rod of the hydraulic cylinder 10 of steeving stretches out, and the clamp that guide cylinder 12 is driven cantilever 5 front portions lifts, and leaves raw material, and the piston rod that falls hydraulic cylinder 6 of bowing this moment cooperates retraction; Telescopic electric machine driven wheel is meshed with the tooth bar 16 of cantilever 5 lateral surfaces, and cantilever 5 is drawn back from mould and hydraulic press.

The 4th step, hydroforming; Hydraulic press utilizes mould that raw material 20-1 is carried out hydroforming, is processed into tee pipe fitting finished product 20-2.

In the 5th step, oil is fallen in material folding: telescopic electric machine driven wheel, and cantilever 5 is advanced, clamp enters the piston rod that falls hydraulic cylinder 6 of bowing behind the forcing press and stretches out, and the piston rod that clamp falls back clamp hydraulic cylinder stretches out, and clamps tee pipe fitting finished product 20-2; The piston rod of hydraulic cylinder 10 of steeving then stretches out, and 20-2 is lifted away from mould with finished product; The hydraulic cylinder that overturns then control flip-arm 13 is done upset, and the inner residual hydraulic oil of tee pipe fitting finished product 20-2 is poured out; The hydraulic cylinder that overturns at last resets.

In the 6th step, blanking: motor 17 drives swiveling gear 2, makes rotation platform 3 drive cantilever 5 and continues to be rotated counterclockwise 90 degree, finished product 20-2 is delivered to finished product district 23, finished product under the piston rod contracted of clamp hydraulic cylinder.

More than describing is explanation of the invention, it or not qualification to invention, institute of the present invention restricted portion is referring to claim, under the situation of spirit of the present invention, the present invention can do any type of modification, for example the present invention is used in the loading and unloading work step of other pipe fitting forming equipment or other large-scale heavy materials; Perhaps the part hydraulic cylinder is replaced with pneumatic cylinder.
