The material of a roller contains Cr3W2V8 alloy steel; a stand below the roller is provided with a supporting roller; a cooling water pipe communicated with a pool is arranged above the roller; and the deliver chain is arranged at the lower part of the supporting roller. The invention has simple process, adopts waste hard steel so as to save the cost, changes wastes into valuables and saves energy sources; the molding machine has simple structure, is suitable for processing screw rods with various threads and has wide range of application; and the screw rod rolled by adopting the process not only has favorable thread quality, but also can improve the strength and the quality of the screw rod.
Description
Technical field
The present invention relates to a kind of moulding process of leading screw and the former that in this technology, is applied to, a kind of specifically screw rod hot rolling molding process and equipment thereof that utilizes hot rolling to realize the hard waste material is made leading screw.
Background technology
The leading screw of use in the market generally is to adopt cold rolling or machined into moulding, and mostly is low-carbon steel material with the material that these methods are processed the leading screw that is.Adopt cold rolling technology system leading screw, it the depth of thread shallow, and because the restriction of technological requirement can only be adopted low-carbon steel materials such as round steel, limitation is big; And the leading screw of employing machined into, though the quality of screw thread is better, process velocity is slow, inefficiency.In addition, now the steel material of the waste and old hard material on the steel market is big, but the material of this material is because the relation of self hardness, and the probability of Li Yonging is lower again, causes serious waste.
Summary of the invention
The present invention be directed to the accumulation of existing waste and old hard steel, and the many defectives that exist in the existing leading screw forming technique, one has provided a kind of screw rod hot rolling molding process, and provides a kind of screw rod hot rolling make-up machine of using in this technical process.
Realize that the technical scheme that the foregoing invention purpose adopts is: a kind of screw rod hot rolling molding process, its technical process is: the blank material is cut into the finished product required size, put it in the heater and heat, when treating that temperature rises to 800-1200 ℃, it is taken out with getting the material pipe, deliver to the screw rod hot rolling make-up machine and carry out screw thread processing, after machining, the carrier chain below the screw rod hot rolling make-up machine is sent finished product; The screw rod hot rolling make-up machine comprises a pair of roll that is installed on the frame, is oppositely arranged, and the power transmission shaft of two rolls is connected transmission with connecting axle with two drives by shaft coupling respectively, and the material of described roll is for containing Cr
3W
2V
8Steel alloy; On the frame of described roll below a backing roll is housed, the top of described roll is provided with the cooling water pipe that is communicated with the pond; The bottom of described backing roll is provided with a carrier chain.
Compared with prior art, the moulding process operation among the present invention is simple, and can adopt waste and old hard steel, not only saves cost, and the waste and old hard steel of long-term accumulation is fully used, and turns waste into wealth, and economizes on resources; Shaping machine structure among the present invention is simple, by changing the material of roll, realize that the screw thread of converted steel is rolling, and thread quality is good, and thread forms is many, is applicable to the leading screw of processing various forms screw thread, and the scope of application is wide; Pan feeding, discharging are simple to operate, increase work efficiency, and realize the regeneration of the old material of slitter edge, create better market economy benefit; Not only thread quality is good but also can improve the intensity and the quality of leading screw to adopt the rolling screw mandrel that comes out of present technique.

The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
Referring to accompanying drawing 1-4, in the present embodiment, this screw rod hot rolling make-up machine, comprise a pair of roll that is installed on the frame, is oppositely arranged 2, the power transmission shaft 4 of two rolls 2 is connected transmission with first drive 8 with second drive 9 with connecting axle 6 by shaft coupling 5 respectively, shaft coupling 5 all adopts Hooks coupling universal coupling, guarantees the minor variations of the steady and angle of transmission.The material of roll 2 is for containing Cr
3W
2V
8Steel alloy, instant heating mould steel, and a backing roll 3 is housed on the frame 1 of two rolls, 2 belows, this backing roll 3 is positioned at the centre position of two rolls 2, and the top of roll 2 is provided with the cooling water pipe 10 that is communicated with pond 12, by water pump 11 water in the pond 12 is squeezed into cooling water pipe 10, also can pour lubricating fluid in the pond 12, like this, the effect of cooling can be played, lubricating can also be realized equipment.The bottom of the rear end of backing roll 3 is provided with a carrier chain 7, and the wheel body of these carrier chain 7 inside is by the motor drives transmission.
The bottom girder that can move horizontally is arranged in the bottom of frame 1, like this, by adjusting the horizontal range of frame 1, adapts to the raw material of various diameters.For the leading screw of rolling different depth, different angles screw thread, need to prepare the roll 2 of plurality of specifications, and the material of roll 2 all adopts Cr
3V
258Steel alloy, can realize the hot rolling of hard steel is handled.
The technical process of this screw rod hot rolling molding process is: with the blank material, be the length that waste and old screw-thread steel cuts into the finished product required size, put it in the heater and heat, the heater in the present embodiment adopts reverberatory furnace, after 1-2 hour, when the temperature for the treatment of screw-thread steel rises to 1000 ℃ of left and right sides, it is taken out with getting material pipe 16, deliver to the screw rod hot rolling make-up machine and carry out screw thread processing, the one end is placed on the carrying roller 14, like this, carrying roller has played the effect of supporting and being with material.Under the extruding of the rotation of carrying roller 14 and two rolls 2, screw-thread steel is forward feeding voluntarily, realize the screw thread processing of entire body, in this process, lubricating fluid flows out from cooling off water pipe 10, the effect of play cooling, lubricating, guarantee that equipment realizes continuously hot rolling, after machining, carrier chain below the screw rod hot rolling make-up machine 7 is sent finished product, deliver to the finished product case, only need staff's arrangement to get final product.
