Specific embodiment
In the following, being further described in conjunction with the drawings and specific embodiments to the utility model:
As shown in Fig. 1,2,3,4,5, it is a kind of pre-shaping device of can of the utility model, is used in Ma Kou
When the can body processing of iron flask, the embryo material after welding is shaped to ellipticity according to scheduled shape, to be adapted to subsequent process.
The pre-shaping device of the utility model includes rack, two pushing blocks 20, yoke frame 30, driving unit and two
Spring 41, wherein installation foundation part of the rack (not shown) as whole device, is provided with a workbench 10, the work
There is sliding rail 11, sliding rail 11 extends along the length direction of workbench 10 on platform 10；What two pushing blocks 20 were slided by sliding block 21
It installs on the slide rail, also, two pushing blocks 20 are oppositely arranged, the two is located at the two sides of yoke frame 30, to adapt to tank
The shape of body, the outside of pushing block 20 is the arched top pushing surface 24 that middle section outwardly protrudes, specifically, can be in pushing block 20
Upper surface outer ledge weld an arc panel, the arched top pushing surface 24 adapts to the shape of can body in a word；Two pushing blocks
20 inside is then a compression zone, which is slidably matched with yoke frame；Yoke frame 30 is located above 10 upper surface of workbench,
It its middle part for being rotatably coupled to workbench 10 and is placed between two pushing blocks 20, there are two press for the outer peripheral edge tool of yoke frame 30
Face 31 is separated by 180 ° between two top pressure faces 31, and the compression zone being then respectively cooperating on two pushing blocks 20, top pressure face 31 is along one
A involute is extended, specifically, being gradually distance from by one end (end a in diagram) towards the other end (end b in diagram)
The central axis of yoke frame 30, that is to say, that when yoke frame 30 rotates clockwise, the compression zone sticked in top pressure face 31 is suitable
Prolong the end a and slides into the end b, since the radius of turn at the end b is greater than the radius of turn at the end a, in above process, compression zone band
Dynamic pushing block 20 is gradually distance from the central axis of yoke frame 30, the i.e. center far from workbench 10, also, when compression zone slides
When to the end b, pushing block 20 is moved to outermost, completes the preforming of can body, due to the outermost side that the end b is top pressure face 31, when by
When splenium is moved at this, even if yoke frame 30 continues to rotate, pushing block 20 will not continue to be displaced outwardly, to be accurately controlled
The traversing distance of pushing block 20, improves the formed precision of can body.Two springs 41 are respectively used to realize that two pushing blocks 20 reset, tool
Body, for spring between workbench 10 and pushing block 20, elastic stress can make pushing block 20 towards the side close to yoke frame 30
To movement, after completing preforming, yoke frame 30 turns to initial position, then the elastic stress of spring returns to pushing block 20 initially
Position.
