Description
The utility model relates to the machinery that metal bar carries out straightening and cut-out, particularly relates to a kind of concrete-bar straightening-cutting machine tool that round steel and Ribbed Bar is carried out straightening and abscinding.
At present, every profession and trade uses the quantity of various round steel, Ribbed Bar more and more, and required precision is more and more higher.Various round steel of the straightening and abscinding that uses in prior art and ribmet muscle aligning cutting-off device, the axis of its straightening mechanism is vertical with the axis of cutting mechanism.Cutting mechanism is an assembling casing, and it is by the belt pulley on driven by motor casing rotation, belt pulley with axle on bevel gear is housed, the bevel gear engagement with on the bent axle drives crankshaft rotating; Spur gear engagement on spur gear and the axis of traction is housed on the bent axle simultaneously, traction wheel is rotated, reinforcing bar is drawn by traction wheel.Because the straightening drum axis is vertical with shearing crankshaft center line, so they can only use two motors to drive straightening drum and cutting mechanism respectively.Bent axle drives slim slide block simultaneously in addition, and the shearing tup is housed on the slim slide block, and the shearing tup pumps by the uniform rotation of bent axle, and shear number of times and determine by drive motors, driving pulley and travelling gear, be changeless.The rotating speed of straightening drum is to be determined by diameter pulley on drive motors rotating speed, the motor and the diameter pulley on the straightening drum, also is constant.And the straightening speed of reinforcing bar is subjected to the variation of bar diameter, intensity and changes.
The aligning cutting-off device of this structure has following deficiency: shearing casing is that separate electrical motor drives, by a pair of belt pulley and several groups of gear drives, and its complex structure, the manufacturing cost height, service precision is poor, and noise is big, is not easy to safeguard and use; Straightening drum axis and cutting mechanism axis normal, so straightening drum also must be driven separately by a motor, so this type must use two motors to drive respectively, so just increased the manufacturing cost and the use cost of machine; Owing to used two motors to drive straightening drum and cutting mechanism respectively, straightening drum rotating speed and cutting mechanism rotating speed are determined that by its transmission mechanism separately each relevant accessory size is once determining that speed just can not change.And reinforcing bar straightening speed in the straightening process alters a great deal with difference, material difference, the hardness difference of bar diameter, and the user is difficult to grasp the straightening speed of reinforcing bar, does not satisfy user's requirement; Straightening speed is subjected to the difference of various factors and changes in the straightening process, and is often asynchronous with hauling speed.When the bigger reinforcing bar of straightening diameter, straightening speed strengthens, and phenomenon is cut by companys of causing, and occurs lacking stub bar, has reduced the utilization rate of material, causes a large amount of wastes to the user; When the less reinforcing bar of straightening diameter, straightening speed reduces, and skidding appears in reinforcing bar, makes the bar straightening rear surface that cut be arranged, and has seriously influenced the mechanical performance of reinforcing bar itself.
The purpose of this utility model is to provide a kind of semi-automatic concrete-bar straightening-cutting machine, and this machine modern design is rational in infrastructure, and power consumption is few, and is simple to operate, is convenient to safeguard that the scope of application is wide, can be widely used on each steel mill and the construction site.
This semi-automatic concrete-bar straightening-cutting machine, form by biscuit frame 1, driving mechanism 4, support 5 and loading device 8 etc., it is characterized in that: assembly guiding structure 2, straightening drum 3, hold down gag 6 and cutting mechanism 7 successively on the top of support 5, the axis of these parts is all on same center line, driving mechanism 4 is installed in the support 5, biscuit frame 1 is placed on the left side of support 5, and loading device 8 is placed on the right side of support; Driving mechanism 4 is that a motor adds an AC frequency conversion speed regulator composition, and the output shaft of motor drives straightening drum 3 and cutting mechanism 7 simultaneously by belt pulley, belt; Pressing plate 11 is installed in the straightening drum 3 and is adjusted screw 12, wheel carrier with two column type guide pillars is installed on the pressing plate 11, installation curve roller 10 on the wheel carrier, in straightening drum axis both sides 6 curve rollers 10 are installed altogether like this, each side is arranged three curve rollers 10 and is become interlaced arrangement, but must guarantee has a pair of curve roller 10 positioned opposite, curve roller 10 is 27 °～55 ° with the angle of axis, distance between two curve rollers is 60～80mm, and the arrival end of straightening drum 3 and the port of export are installed one respectively and imported die sleeve 9 and belt pulley 14.
Drawings and Examples:
Fig. 1 is semi-automatic concrete-bar straightening-cutting machine structural representation
Fig. 2 is the straightening drum structural representation
Fig. 3 is the gatherer structural representation
Fig. 4 is three kinds of arrangement form schematic diagrames of curve roller
When reinforcing bar is carried out straightening, at first reinforcing bar is placed on the biscuit frame 1, arc groove from two guide-in rollers 15 of gatherer 2 of reinforcing bar is passed, enter then and import die sleeve 9 and straightening drum 3, through curve roller 10, after belt pulley 14 passes, enter hold-down mechanism 6, enter material bearing shelf 8 at last.When motor 4 rotates, drive straightening drum device 3 and cutting mechanism 7 simultaneously.Belt pulley 14 drives straightening drum 3 and rotates.Adjust the drafts of screw 12 adjustment curve rollers 10, reinforcing bar is exerted pressure.Reinforcing bar is when the curve roller 10, and under the transmission of curve roller 10, reinforcing bar moves axially, several elastoplasticity correcting units that the curve roller 10 by interlaced arrangement is constituted, and each section obtains repeatedly crooked; By the curve roller of a pair of interlaced arrangement, can better bite reinforcing bar, reinforcing bar is travelled forward; And reinforcing bar is after going out straightening drum, and reinforcing bar is whipping not, obtains better straightening effect.Reinforcing bar did not both scratch after straightening simultaneously, did not have twisted phenomena yet.Reach the purpose of bar straightening.When straightening drum 3 rotates, the motion that the tup in the cutting mechanism 7 is not also stopping up and down.After bar straightening enters material bearing shelf 8 and reaches scale, drive the cutter platform and move forward, when the cutter platform moved on to below the tup, tup impacted the cutter platform, realizes cutting off action, and the cutter platform is by spring reset then.Realize the process that bar straightening is cut off.
