Summary of the invention
The objective of the invention is to design a kind of multi-functional serpentine spring process units.
What the present invention will solve is existing serpentine spring (S shape spring) process units, and automaticity is low, can't accomplish directly to go out from Production for Steel Wire the problem of high-quality steel wire or fixed length steel wire.
Technical scheme of the present invention is: the present invention includes draw drum, serpentine spring machine and cutting machine, be provided with straightener between draw drum and the serpentine spring machine, be provided with buffer between serpentine spring machine and the cutting machine, connect feeder behind the cutting machine.
Advantage of the present invention is: automaticity is low, directly goes out high-quality steel wire or fixed length steel wire from Production for Steel Wire.And low cost of manufacture of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in the figure, the present invention includes draw drum, serpentine spring machine and cutting machine.Be provided with straightener between draw drum and the serpentine spring, be provided with buffer 10 between serpentine spring machine and the cutting machine, connect feeder behind the cutting machine.Draw drum comprises base 24 and plate rail 25, and plate rail 25 is loaded on the base 24.
Straightener comprises straightening dish 3, big straightening wheel 22, reinforcing bar inlet sleeve 23, reinforcing bar outlet sleeve 4, the first straightening wheels 5 and the second straightening wheels 6, and is spaced apart many to ditty through ship 2 on the straightening dish 3.Big straightening wheel 22 has three, is angular distribution in straightening dish 3 bottoms.Reinforcing bar inlet sleeve 23 is located at straightening dish 3 bottoms two sides respectively with reinforcing bar outlet sleeve 4.Reinforcing bar outlet sleeve 4 is connected with the second straightening wheels 6 with the first straightening wheels 5 successively.The first straightening wheels 5 have five straightening wheel, and wherein two straightening wheels are arranged in a row, and three straightening wheels are lined up another row in addition, and this two teases and ridicule through ship and be arranged in parallel.The second straightening wheels 6 are identical with the structure of the first straightening wheels 5.
The serpentine spring machine comprises frame 21, be located at swinging block 7, gear-box 9 on the frame 21, be located at eccentric wheel 8, S shape spring delivery track case 20 and connecting rod 19 on the gear-box 9.Swinging block 7 is connected with eccentric wheel 20 through connecting rod 19, and S shape spring delivery track case 20 is located at the bottom of frame 21, and reinforcing bar 1 drives swinging block 7 actions through eccentric wheel 8, obtains S shape spring 1-1.
Buffer 10 is made up of the frid of two intersections.
Cutting machine comprises frame 16, runner, cutting knife 12, is located at the cutting control module in the frame control cabinet 16-1, and serpentine spring is carried frid 11, servomotor 17 and is located at the conveyance gear 18 on the servomotor 17.The conveying gear teeth 18 of conveyance gear pass serpentine spring and carry frid 11.Being stuck on the S shape spring 1-1 of conveyance gear 18.
Feeder comprises blanking frame 15, is located at the blanking frid 15-1 on the blanking frame 15, is located at the turnover panel 26 under the blanking frid 15-1; S shape spring delivery wheel 13 and automatic telescopic cylinder 14; S shape spring delivery wheel 13 is affixed on the blanking frid 15-1, and when work, touch S shape spring 1-1.Automatically the push rod of telescopic cylinder 14 withstands on a side of turnover panel 26, turnover panel 26 opposite sides and blanking frid 15-1 avris hinged (or pivot joint).
The effect of cutting control module is the cut-out action of control cutting knife, and the rotation of servomotor, S shape spring delivery wheel rotate and telescopic cylinder 14 flexible automatically.After cut fixed length serpentine spring was transported on the blanking frid 15-1, the cutting control module indicated automatic telescopic cylinder 14 to shrink, and turnover panel 26 is turned down, and the fixed length serpentine spring of cut-out falls.Subsequently, telescopic cylinder 14 push rods stretch out automatically, and turnover panel 26 rolls up.
