3021, the lower surface of adjustment gear 35 is pressed against on free ball 3021.
Further, for the arc block 38 when near fixing seat 36, the outer surface of arc block 38 is no more than annular
The outer peripheral surface of groove 322;The arc block 38 is when farthest away from fixing seat 36, outer surface and the mold base 32 of arc block 38
Outer peripheral surface flushes.
Further, the upper surface center of the positioning groove 11 is equipped with groove, is fixed with electromagnet 12 in groove.
Further, maintenance window 321 is offered on the mold base 32.
Working principle of the utility model is:
1, metal drum is placed in positioning groove 11 and is fixed by the absorption of electromagnet 12, starting lifting cylinder 26 makes to squeeze
Pressure protective device 3 protrudes into the lower section in metal drum, and the outer wall of mold base 32 sticks on the inner wall of metal drum at this time;
2, start lifting motor 21, make lifting seat 23 that extrusion die 25 be driven to be moved to position corresponding with mold base 32
It sets, the semi-cylindrical hill 251 in extrusion die 25 is right against the annular groove 322 in mold base 32 at this time;
3, starting adjusts motor 34, so that adjustment gear 35 is rotated, the tip chute 351 in adjustment gear 35 has occurred
After the rotation of certain angle, the connecting column 371 in tip chute 351 then will drive telescopic shaft 37 and carry out in fixing seat 36
It is flexible, finally make arc block 38 move outwardly to flush with the outer peripheral surface of mold base 32, arc block 38 is also attached to gold at this time
On the inner wall for belonging to bucket;
4, starting, which squeezes cylinder 24, squeezes two extrusion dies 25 to the outer wall of metal drum, semi-cylindrical hill 251
It presses to annular groove 322 and carries out shaping work, since the outer peripheral surface of mold base 32 and the outer surface of arc block 38 are difference positions
In annular groove 322 upper and lower position and stick on metal drum inner wall so that semi-cylindrical hill 251 is squeezing metal drum
When wall body, the metal drum wall body at other positions will not be had an impact, specificity greatly improves;
5, after completing extrusion forming, adjustment gear 35 inverts under the action of adjusting motor 34, so that arc block 38 is bounced back, so
Crush protector 3 rises a certain distance under the action of lifting cylinder 26 afterwards, and extrusion die 25 is acted in lifting motor 21
It is lower to rise corresponding distance, extrusion forming again then is carried out to the wall body of metal drum.
Since arc block 38 is when near fixing seat 36, the outer surface of arc block 38 is no more than the outer of annular groove 322
Surface is enclosed, so that metal drum, after the completion of extrusion forming, crush protector 3 is convex on metal drum inner wall when moving up
The movement of crush protector 3 will not be hindered by playing (groove after being extruded), and crush protector 3 can be under in metal drum
Up cooperation extrusion die 25 carries out extrusion forming gradually to metal drum wall, convenient and efficient.
