Abstract
The utility model relates to the improvement of a flattener for cold-rolled reinforcing bars. A straightening roller which is installed on the bearing seat in a frame adopts a hyperbolic concave wheel shape; an angle which is from 15 DEG to 45 DEG, formed by each of the straightening rollers and the frame is misplaced on the center line of a main shaft; one side of the upper part of a positioning block is connected with a switch of an electric apparatus and is connected with the electromagnet on a blanking frame by conducting wires and the electromagnetic switch of a cutting device to control for automatically cutting and blanking for cold-rolled reinforcing bars. The utility model has the advantages of simple structure, simple principle and no damage for cold-rolled reinforcing bars.
Description
The utility model relates to the improvement of cold rolled reinforcing steel bar with ribs straightener.
At present, the bar straightening machinery that building trade is used, can only align plain bar, its structure is such, aligning part is to adopt hot candied eye mutual dislocation in the framework of rotation, and workpiece (round steel or Ribbed Bar) alternating bending in framework of being aligned is pulled out by traction wheel and reached the aligning purpose, fixed ruler cutting is mechanical type control, and the structure of blanking frame can only be 1.5 meters scope internal cutting off reinforcing bars and automatic blanking in reinforcing bar length.When using this aligning machinery that cold rolled reinforcing steel bar with ribs align, be the carbide alloy cover because hot candied eye adopts, the damage of causing 1/3-1/2 for the rib of cold rolled reinforcing bar, and about intensity reduction 100Mpa; Be not suitable for the aligning of cold rolled reinforcing steel bar with ribs is used.
The utility model purpose provides and a kind ofly adopts a plurality of appearances to be processed into recessed smoothing roll of taking turns shape of hyperbola and angled the dislocation on spindle centerline, align reinforcing bar adjustable length and the not damaged cold rolled reinforcing steel bar with ribs straightener by electric switch control cut-out and automatic blanking.
The utility model is made up of straightening mechanism, shearing device, locating piece, blanking electrical equipment, the smoothing roll of straightening mechanism is installed on the bearing block, bearing block is by being bolted on the framework, each smoothing roll and framework Cheng Du misplace on the center line of main shaft to miter angle, the electromagnetic switch of shearing device is connected mutually with the Isolating Switch of shearing device, by the angle chain device for discharging is installed on the blanking frame, device for discharging is connected with the electromagnetism iron phase by connecting rod, a side that is installed in the locating piece top on the blanking frame is connected with extension spring, and opposite side is connected with electric switch; Electric switch is connected with electromagnet with electromagnetic switch respectively by lead; The outer surface of smoothing roll is processed into the recessed shape of taking turns of hyperbola.
The aligning that the utlity model has cold rolled reinforcing steel bar with ribs can not damage its " muscle " because of friction, do not reduce its intensity, electric switch adopts magnet control, can be by the aligning labor and materials at 300-12, any scale in the 000mm scope, characteristics such as error is little, can align the cold rolled reinforcing steel bar with ribs between the nominal diameter 4-12mm, and structural principle is simple.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model straightening mechanism structural representation.
Accompanying drawing 3 is the utility model shearing device B-B cutaway view.
Accompanying drawing 4 is the utility model locating piece part A-A cutaway view.
Below in conjunction with accompanying drawing the utility model is further described:
The outer surface that is installed in the smoothing roll 1 on the bearing block 2 is processed into the recessed shape of taking turns of hyperbola, each smoothing roll becomes 15 degree-miter angles to misplace on the center line of main shaft 4 with framework, bearing block is by being bolted on the framework 3, the cutting knife of shearing device is controlled by Isolating Switch, Isolating Switch is connected mutually with electromagnetic switch 5, and be subjected to magnet control, by the angle chain device for discharging is installed on the blanking frame 6, device for discharging is provided with pull bar 7, the upper end of pull bar is by electromagnet 8 adhesives action, after being cut off, labor and materials fall automatically, locating piece 9 also is installed on the blanking frame, one side of locating piece is connected with extension spring 10, and opposite side is connected with electric switch 11, and electric switch is connected with electromagnet with electromagnetic switch respectively by lead.Operation principle of the present utility model is such, the cold rolled reinforcing steel bar with ribs that to be aligned is put into straightening mechanism, rotating frame is rotated by driven by motor, the recessed smoothing roll of taking turns of the many hyperbolas to mutual dislocation that set within it rotates, and is aligned labor and materials to move under the effect of smoothing roll, and labor and materials are by the blanking frame, behind required length scaling, withstand on the bottom of locating piece 9, and the extension spring of a side on the locating piece is spurred, the locating piece opposite side contacts with electric switch; By the electromagnetic switch of lead control shearing device, will be cut off automatically by the aligning labor and materials, electric switch is controlled electromagnet by lead simultaneously, and electromagnet is inhaled connecting rod 7 moving and is driven device for discharging, is aligned labor and materials to fall automatically, finishes the Ribbed Bar aligning.The smoothing roll setting angle of the utility model straightening mechanism is adjustable, can satisfy the different-diameter cold rolled reinforcing steel bar with ribs is aligned, distance between shearing device and locating piece and the blanking electrical equipment is adjustable, to satisfy requirement to the different length cold rolled reinforcing steel bar with ribs, the utility model does not have tangible wear trace to cold rolled reinforcing steel bar with ribs in use.Do not influence the intensity of cold rolled reinforcing steel bar with ribs.
Claims (2)
1, not damaged cold rolled reinforcing steel bar with ribs straightener, be by straightening mechanism, shearing device, locating piece, blanking electrical equipment is formed, the smoothing roll 1 that it is characterized in that straightening mechanism is installed on the bearing block 2, bearing block is by being bolted on the framework 3, each smoothing roll becomes 15 to spend to miter angle and misplace on the center line of main shaft 4 with framework, the electromagnetic switch 5 of shearing device is connected mutually with the Isolating Switch of shearing device, by the angle chain device for discharging is installed on the blanking frame 6, device for discharging is connected with electromagnet 8 mutually by connecting rod 7, a side that is installed in locating piece 9 tops on the blanking frame is connected with extension spring 10, and opposite side is connected with electric switch 11; Electric switch is connected with electromagnet with electromagnetic switch respectively by lead.
