Description

One kind having the corrosion resistant steel alloy screw barrel of highly abrasion-resistant
Technical field
The utility model is related to screw technique fields, and in particular to one kind having the corrosion resistant steel alloy machine barrel of highly abrasion-resistant Screw rod.
Background technology
The ability that currently used nut stem material resists hydrogen-chloride etching is low, and wear-corrosion resistance is poor, has a single function, together A piece screw barrel can only prepare a kind of screwed pipe, prepare the machine barrel that various sizes of screwed pipe prepares various specifications if necessary Screw rod, this not only needs to spend a large amount of money, while the maintenance expense in later stage is also with raising, the screw barrel of different size Certain place is occupied, these factors affects have arrived the production cost of enterprise, and equipment, consumptive material, artificial etc. are a series of all to be risen Gao Liao, ad hoc meter is a kind of with the corrosion resistant steel alloy screw barrel of highly abrasion-resistant in view of the above problems for the utility model thus.
Invention content
To overcome above-mentioned deficiency, the utility model to provide a kind of with the corrosion resistant steel alloy machine barrel spiral shell of highly abrasion-resistant Bar.
Technical solution adopted by the utility model to solve its technical problems is:One kind having the corrosion resistant conjunction of highly abrasion-resistant Golden steel screw barrel, including steel alloy center-pole, screw head, steel alloy center extension rod, hollow screw, center-pole rear cover, It is characterized in that:The screw head is connected by bolt arrangement with the end of steel alloy center-pole one end, steel alloy center-pole The end of the other end be connected with the end of one end of steel alloy center extension rod by bolt arrangement, steel alloy center extends The end of the other end of bar is connected by bolt arrangement with center-pole rear cover;The hollow screw is placed on steel alloy center-pole On, and one end end of hollow screw is connected by bolt arrangement with screw head, other end end is by bolt arrangement in Core bar rear cover is connected.The inner hollow of the hollow screw, outer surface be equipped with helicla flute or Conical Spiral Groove, while in The hollow diameters of the inside of empty screw rod are more than the diameter of steel alloy center-pole, and steel alloy center-pole is embedded in hollow screw.
The hollow screw, which is equipped with, is more than 1, and adjacent two hollow screws are joined end to end using bolt arrangement.
The steel alloy center extension rod, which is equipped with, is more than 1, and adjacent two steel alloy centers extension rod uses bolt Structure joins end to end.
The screw head (3) is equipped with groove (4).
The hollow screw is divided into three sections i.e. feeding section, and the thickness of compression section, homogenizing zone, hollow screw is 2.5- 4cm。
The utility model by using be use highly abrasion-resistant corrosion-resisting alloy steel.Such as 34CrAlNi, 31CrMo12, it is real It is indeformable under screw at high temp in present extrusion, it is wear-resistant, prolong the service life, corrosion-resistant, high intensity can bear to turn round greatly Square, high speed turn, and there is good machinability, alloy steel material to be better than other materials, domestic and international nut stem material is energetically It promotes the use of, while the utility model realizes the screw barrel of different size by way of splicing and is nested and is not necessarily to again make It is standby, as long as by the hollow screw set and steel alloy center-pole of the size of needs, it is convenient and practical, while can also be by more The control of length is realized in root hollow screw head and the tail docking, is used and is not only facilitated, but also is easy to operate understandable.
Description of the drawings:
Fig. 1 is the structural schematic diagram of the utility model
In figure:1. steel alloy center-pole;2. screw head;3. steel alloy center extension rod;4. hollow screw;5. after center-pole Lid.
Specific implementation mode:
The structural principle of the utility model is described further below in conjunction with the accompanying drawings.
The utility model one kind as shown in Figure 1 has the corrosion resistant steel alloy screw barrel of highly abrasion-resistant, including steel alloy Center-pole 1, screw head 2, steel alloy center extension rod 3, hollow screw 4, center-pole rear cover 5, screw head 2 by bolt arrangement with The end of 1 one end of steel alloy center-pole is connected, and the end of the other end of steel alloy center-pole 1 passes through bolt arrangement and steel alloy The end of one end of center extension rod 3 is connected, and the end of the other end of steel alloy center extension rod 3 is by bolt arrangement in Core bar rear cover 5 is connected;Steel alloy center extension rod 3, which is equipped with, is more than 1, and adjacent two steel alloy centers extension rod 3 uses Bolt arrangement joins end to end;Hollow screw 4 is placed on steel alloy center-pole 1, and one end end of hollow screw 4 passes through spiral shell Stud structure is connected with screw head 2, and other end end is connected by bolt arrangement with center-pole rear cover 5;Hollow screw 4 it is interior Portion is hollow, and outer surface is equipped with helicla flute or Conical Spiral Groove, while the hollow diameters of the inside of hollow screw 4 are more than steel alloy The diameter of center-pole 1, steel alloy center-pole 1 are embedded in hollow screw 4;Hollow screw 4, which is equipped with, to be more than in 1, adjacent two Empty screw rod 4 is joined end to end using bolt arrangement;Hollow screw 4 is divided for three sections i.e. feeding section, compression section, and homogenizing zone is hollow The thickness of screw rod 4 is 2.5-4cm;Screw head 2 is equipped with groove.
