Technical field

The utility model relates to a kind of building material production facility, relates in particular to the cold rolling unpowered milling train of turning round of spiral reinforcement or three types.

Background technology

This is the structure that we can see everywhere in the construction site for an armored concrete, in order to improve the bond stress of cement face, strengthen the service life of steel and concrete component and distortion globality under external force, require to use cold-rolled threaded reinforcing steel, intensity height because of cold-rolled threaded reinforcing steel, plasticity is big, and contact surface increases.The wire-drawing equipment that is used for processing cold-rolled threaded reinforcing steel has multiple structure, for to the heart, mandrel has adjustment of the lever of employing bolt and the single adjustment of wedge of three rollers, because inconvenience is installed in existence, adjustment is not easy to select shortcoming, the user is also constantly improving them.In the production equipment, motivation utilization traction reinforcing bar power organic headband motor and not charged is produced.The latter uses more in the production of minor diameter spiral.

Along with this respect technological progress, in Chinese patent application, also there are some to relate to the application part of this respect, be 88217140.2 as application number and be called " cold-rolled threaded reinforcing steel " etc., through the related pertinent literature of retrieval, not with the equipment of the identical structure described in the present specification.Nearest application number is 200720174186.8 and is called " a kind of process units of spiral reinforcement " though equipment adopts whirligig to satisfy the automatic adjustment center needs of spiral, be installed in the end with diaphragm capsule, install heat abstractor additional, solve the heat dissipation problem of mould in the production process, thereby increasing substantially of die life, in production practices, production cost is still higher, can solve the product supply problem, but economic benefit and social benefit have much room for improvement.

Summary of the invention

The present invention seeks to develop a kind of process units of cold rolling spiral reinforcement, except solving the automatic adjustment center of spiral, solve mould in the production process heat radiation and service life problem, productivity ratio and production cost problem.Finished production equipment by research, this machine adopts three-jaw self-centering chuck, is formed centrally helical angle in the displacement of deck assembly, and in the reinforcing bar motion, roll is along 360 ° of rotations, and the helical angle of reinforcing bar produces automatically, becomes needed product with reinforcing bar is rolling.

The utility model solves with following technical scheme,

Spiral reinforcement, the cold rolling unpowered milling train of turning round of three types, it is mainly by deck assembly 13, scroll chuck 14, mill stand 16, raw material reinforcing bar 17, finished product spiral reinforcement or three types are cold rolling turns round 18, and wire drawing machine fixed traction 19 is formed; Scroll chuck 14 is fixed on the main spindle box 15, and main spindle box 15 is fixed on the mill stand 16, and mill stand 16 is fixed on the foundation bolt on basis; Third Mate's deck assembly 13 is fixed on the three-jaw self-centering chuck 14, raw material reinforcing bar 17 is by main spindle box 15, pass the centre bore of the scroll chuck 14 that is fixed on the main spindle box 15 and the center by Third Mate's deck assembly 13 again, stretch out that finished product spiral reinforcement behind the center or three types are cold rolling to be turned round 18 and be placed in the place ahead, by wire drawing machine fixed traction 19.

Above-mentioned spiral reinforcement, the cold rolling unpowered milling train of turning round of three types, its deck assembly 13 be by roll 1, bearing 2, lining 3, interior locking nut 4, outer locking nut 5, deck 6, axle sleeve 7, oil nozzle 8, oil 9, axle 11 is rolled with back-up ring 10 in the hole, round nut 12 is formed, and roll 1 is equipped with bearing 2, it is fixed on the axle sleeve 7 then, with interior locking nut 4, outer locking nut 5 they are fixed on the deck 6 again, form deck assembly 13 integral body then.

Above-mentioned spiral reinforcement, the cold rolling unpowered milling train of turning round of three types, its roll 1 can be changed, and changes the diameter dimension that roll is adjusted spiral reinforcement; Can satisfy spiral reinforcement or the cold rolling needs of turning round of three types of rolling diameter 4～12mm.

The beneficial effects of the utility model, equipment self is unpowered, bar roll is installed on the deck assembly, be fixed on the three-jaw self-centering chuck, adopt wire drawing machine traction whirligig to make three-jaw self-centering chuck, be formed centrally helical angle in the displacement of deck assembly, in the reinforcing bar motion, roll is along 360 ° of rotations, the helical angle of reinforcing bar produces automatically, become needed product with reinforcing bar is rolling, the deck assembly installs refueling device additional, solves the lubricated and heat dissipation problem of mould in the production process, thereby increasing substantially of roll service life, reduce maintenance time, energy savings, production cost further reduces, constant product quality, handled easily, safe in utilization, the use of equipment has obtained good economic benefit.
