Abstract

The invention discloses a rebar diameter reducer which consists of a rebar unreeling frame, a stress balancing mechanism and a rolling mechanism; the rebar unreeling frame consists of a base, a rotating shaft and a turntable; a rebar reel is sleeved above the turntable on the rotating shaft; the stress balancing mechanism consists of a vertical plate, a rebar bending wheel, a rebar surface powder coating box and a rebar diameter reducing sleeve; the rebar bending wheel is arranged on the vertical plate in a triangular shape; the rebar surface powder coating box is arranged at the front end of the vertical plate; the rebar diameter reducing sleeve is arranged at the outlet end of the rebar surface powder coating box; the rolling mechanism consists of a rolling motor, a gear case and a rolling tray; the rebar diameter reducing sleeve forms a ring shape; a middle diameter reducing hole is embedded with an alloy sleeve; a cooling water jacket is processed on the outer brim, and a water inlet pipe and a water outlet pipe are arranged on the cooling water jacket. By adopting the technical scheme, the alloy sleeve with large hardness is arranged on a lining of the rebar reducing sleeve; the abrasion of the inner sleeve can be released; the cooling water jacket is arranged outside the rebar diameter reducing sleeve; the temperature can be reduced, and the hardness of the alloy sleeve is kept at a low temperature so as to improve the durability of the rebar diameter reducing sleeve.

Description

The reinforcing bar size reducing machine

Technical field

The invention belongs to reinforcing bar drawing undergauge equipment technical field, relate to a kind of reinforcing bar size reducing machine.

Background technology

The reinforcing bar of the standard model of producing from manufacturing enterprise, its diameter is bigger when being used to process iron nail, carry out the processed of diameter reduction to reinforcing bar; In the prior art, the reinforcing bar size reducing machine is made up of reinforcing bar unwinding rack, stress equilibrium mechanism and rolling-up mechanism, and the reinforcing bar unwinding rack is made up of base, rotating shaft and rotating disk; Base support on the ground; Rotating shaft is installed on the chassis, and rotating disk is installed in the bottom of base, and the reel reinforcing bar is sleeved on the rotating disk of rotating shaft; Stress equilibrium mechanism is made up of put on powder box and reinforcing bar undergauge cover of riser, bar bending wheel, rebar surface; The bar bending wheel has three; Triangular in shape being installed on the riser, the front end top mounting reinforcing steel bars surfaces coated powder box of riser, reinforcing bar undergauge cover is installed in rebar surface and is coated with the powder box port of export; Rolling-up mechanism is made up of winding motor, gearbox and closed reel, and winding motor connects gearbox with belt, and the other end of gearbox is installed closed reel, and the reinforcing bar of rolling is on closed reel.

The reinforcing bar size reducing machine is when work, and reinforcing bar is by emitting on the unwinding rack, and the powerful tractive force that relies on winding motor to produce spurs; Reinforcing bar is when taking turns through three bar bendings of stress equilibrium mechanism, and by bending, stretching, the internal stress of reinforcing bar obtains balance from different directions; When reinforcing bar is coated with powder box in process; The smoothers that last layer reduces friction is smeared on the surface, and reinforcing bar is squeezed into the slightly little fine steel rib of diameter by reinforcing bar undergauge cover through reinforcing bar undergauge cover the time afterwards.

Because when reinforcing bar was extruded in reinforcing bar undergauge cover, undergauge cover inner ring was stressed bigger, produces bigger frictional force, the undergauge cover can produce higher temperature, and the wearing and tearing of inner ring can be quickened, and therefore the loss of reinforcing bar undergauge cover is bigger in actual production.

Summary of the invention

The present invention is directed in the prior art, the reinforcing bar undergauge is enclosed within the problem that wearing and tearing are very fast when using, loss is bigger, and a kind of reinforcing bar size reducing machine is provided; This reinforcing bar size reducing machine is made up of reinforcing bar unwinding rack, stress equilibrium mechanism and rolling-up mechanism, and the reinforcing bar unwinding rack is made up of base, rotating disk and rotating shaft, and base support on the ground; Rotating disk is installed on the base; Rotating shaft is installed on the rotating disk, and the reinforcing bar reel is sleeved in the rotating shaft of rotating disk, and reinforcing bar is by emitting on the reinforcing bar reel; Stress equilibrium mechanism is made up of put on powder box and reinforcing bar undergauge cover of riser, bar bending wheel, rebar surface; The bar bending wheel has three; Triangular in shape being installed on the riser, mounting reinforcing steel bars surface, the front end of the riser top box of putting on powder, reinforcing bar undergauge cover are installed in the rebar surface box port of export of putting on powder; Rolling-up mechanism is made up of winding motor, gearbox and closed reel, and winding motor connects gearbox with belt, on the other end output shaft of gearbox closed reel is installed; The reinforcing bar of rolling is on closed reel; Be installed in the put on powder reinforcing bar undergauge cover of the box port of export of rebar surface, be annular, be inlaid with the alloy cover on the undergauge hole at middle part; Be processed with cooling jacket on the outer, water inlet pipe and outlet pipe are housed on the cooling jacket.

Adopt technique scheme, in the bigger alloy cover of reinforcing bar undergauge cover liner dress hardness, the wearing and tearing of cover in can slowing down; Outside reinforcing bar undergauge cover, cooling jacket is installed; Can reduce its temperature, alloy is enclosed within keep hardness under the low temperature, thereby improve the durability of reinforcing bar undergauge cover.
