The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and a preferred embodiment, to help understanding content of the present invention.
As shown in Figure 1, be a kind of more excellent embodiment of cold rolling ribbed bar continuous production device, comprising:
By passive milling train 100 and the cold rolling unit formed of milling train 200 initiatively, be used for the reinforcing bar raw material is carried out cold rolling tube reducing and at surface formation cross rib;
Annealing device 300 is installed in cold rolling unit downstream position, is used for the Ribbed Bar of cold rolling unit processing is carried out the online annealing temperature that is heated to, and the heat treatment of annealing is to improve the percentage elongation of reinforcing bar;
Numerical control flying shear 400 is used for as required the reinforcing bar of producing being carried out accurate scale and cuts out;
Material collecting device includes first winder 500 and 600, two winders of second winder and can hocket and batch rewinding, is used to produce wire rod reinforcing bar product; Turn over steel packing material collecting device 700 in addition, the straight reinforcing bar that is used for fixed length carries out rewinding.
The concrete structure of passive milling train and active milling train can be as shown in Figures 2 and 3, passive milling train comprises and parallel tube reducing roll 11a, the 11b of a pair of vertical installation that is installed on the support 12 adopts straight roller, be used for wire rod is realized that cold extrusion alleviates, do not need power set.Also has an active milling train that is installed in passive milling train downstream position.
In conjunction with shown in Figure 2, initiatively milling train comprises that level is installed in molding roller 21a, the 21b of the pair of parallel on the support 22, and molding roller is provided with the used decorative pattern of spreading rib.Main motor 26 is realized the output of slowing down by belt pulley and belt by reductor 25, reductor 25 connects by the power shaft of shaft coupling with double helical tooth roller box 24, and two output shafts that rotate synchronously of gear-box 24 are respectively by Hooks coupling universal coupling 23a, 23b driven in synchronism two molding roller 21a, 21b.Enter wire rod between molding roller 21a, the 21b of active milling train 200 by the gap between tube reducing roll 11a, the 11b of passive milling train 100 like this, after adjusting the gap between tube reducing specification and the molding roller, start main motor 26, molding roller 21a, 21b are driven by transmission mechanism by main motor 26, molding roller 21a, the 21b wire rod of nipping rolles over out required rib, and utilize the rotation of molding roller to draw wire rod forward, wire rod is under the pulling force effect, the tube reducing roll 11a, the 11b that drag on the passive milling train 100 rotate, and the extruding wire rod carries out tube reducing.Therefore wire rod remains certain tension force between active milling train 200 and passive milling train 100, can not occurring initiatively, rolling mill line speed is slower than passive milling train and causes the continuous of bar bending influence production, the Ribbed Bar of producing is not subjected to alternating bending, and internal tiny crack is few and little, exquisite appearance; Passive rolling mill line speed also can not occur is slower than initiatively milling train and reinforcing bar is broken or crackle is occurred and reduce the strength of materials.So two milling trains are gone slick, product appearance is attractive in appearance, and intensity is good.
As shown in Figure 3, initiatively support 22 bottoms of milling train are provided with the roll gap adjusting device 204 that is used to adjust the molding roller roll gap, simultaneously with reference to shown in Figure 4, form by the worm screw 241 that is adjusted motor 23 drivings and with worm screw 241 engagements and by the turbine 242 that is installed on the push rod 243 of worm drive, the top of push rod 243 fixes on molding roller bearing at end seat place, drive the rising by push rod 243 and descend and adjust moulding roll seam size by adjusting motor 23, with the production requirement of the reinforcing bar that adapts to different size.Same reason also is provided with this roll gap adjusting device to regulate the gap length of tube reducing roll on passive milling train.Adjust motor and adopt stepper motor, to carry out the roll gap adjustment conveniently, flexibly.
Annealing device 300 can adopt intermediate frequency of the prior art or HF induction heating apparatus, mode of heating with other is compared, adopt middle and high frequency induction heating equipment, firing rate is fast and be easy to control, can directly carry out heating anneal and handle, reinforcing bar is got final product by this firing equipment with certain speed the continuity reinforcement(bar) on the production line.
Adopt existing numerical control flying shear, can realize that flying shear follows the tracks of production line at a high speed and shear synchronously.
Turn over steel packing material collecting device as shown in Figure 5 and Figure 6, comprise be installed on the frame 79 by a plurality of transmission roller-ways that constituted by motor-driven horizontal transmission roller 72, be used to transmit the reinforcing bar after the scale processing.The left and right sides, transmission roller-way top that is positioned at transfer roller 72 formations is provided with side plate 73a, 73b, forms the feeding groove that is roughly U-shaped with transmitting roller-way.Be provided with baffle plate 71 retainings at the feeding groove tail end at the tail end that transmits roller-way, prevent to continue to move forward, it is stopped in the storing section with the reinforcing bar product that blocks behind the scale.
As shown in Figure 5, Yi Bian material toggling pawl 74 can constitute along the driving lever that outwards protrudes out by equilateral triangle corpus unguis and three drift angle places of equilateral triangle corpus unguis.This material toggling pawl structural strength is well not yielding.
The groove 78 that connects material can be groove always, also can be arranged in by a plurality of U type supports of installing on support, and to reduce material usage, the neutral gear between the support is convenient to personnel and is carried out the maintenance, repair maintenance near feeding groove simultaneously, and the packing operation.Certainly, for ease of moving, the groove that connects material also can replace with dolly.
After the wire rod raw material that the production reinforcing bar is used carries out cold rolling tube reducing and forms rib through cold rolling unit, product strength can reach requirement, but percentage elongation is lower, enter annealing device and be heated to annealing temperature this moment, make product in follow-up process, lower the temperature annealing naturally to reach the purpose that improves percentage elongation, basis is that the length that production wire rod or the setting of vertical bar product are cut out is cut out by the numerical control flying shear then, then carry out rolling if produce the wire rod product, produce the vertical bar product and then carry out rewinding by turning over the steel baling press by winder.
