Abstract
The present invention relates to a steel strand parting and twisting device which can part seven prestressing steel strands without affecting the mechanical properties of the steel strands or damaging materials. The steel strand parting and twisting device comprises a wire parting wheel 1 and a revolving drum 2, wherein the wire parting wheel 1 is arranged in the revolving drum 2 and is connected with the revolving drum 2; the center position of the wire parting wheel 1 and the symmetrical positions at the same circumference are respectively provided with a center wire hole 1.1 and six side wire holes 1.2; after being parted, seven steel wires of a steel strand penetrate through the seven wire parting holes and are then twisted after being pulled for certain distances; when the wire parting wheel rotates, the steel strand at the rear is parted, and the front seven steel wires penetrating through the wire parting center hole and the side wire parting holes are simultaneously twisted at the same speed. Therefore, the steel strand parting and twisting device of the present invention can easily part and twist prestressing steel strands without affecting the mechanical properties of the steel strands to the greatest extent.
Description
Technical field:
The present invention relates to a kind ofly seven prestress wires are opened and do not influenced the mechanical property of steel strand wires or do not damage the steel strand parting and twisting device of material.
Background technology:
Coating steel strand wires with good antiseptic property are by the steel strand wires after Overheating Treatment, carry out coating again and handle, and to reach isolated corrosion-resistant effect, wrap the non-bending steel cable of HDPE, the steel strand wires of coating epoxy resin etc. again as applying grease.Way in the past is a whole steel strand wires process plater, finishes coating and applies.Technical process is simple, the efficient height.But there is the halfway problem of coating in this technical process.Seven steel strand wires that steel wire is twisted into, after heat treatment six roots of sensation limit silk and central hair closely are intertwined, and coating material can only cover limit silk outer periphery, and central hair and silk inboard, limit can't arrive, and cause anticorrosion blind area, influence the long-term antiseptic effect of product.
For solving the inadequate problem of coating, there is the coating of increasing to apply methods such as pressure or raising coating temperature usually.Pressure when increasing the coating of grease material can increase the amount that grease enters the steel wire gap, improves the filling state; Improve the temperature of dewaxing, can increase the effect of impregnation may of wax liquid, and make wax keep liquid time lengthening, thereby make the steel wire gap fill more wax steel wire.Though these two kinds of methods have all been improved the filling extent of coating to some extent, not effective method.And for coating materials such as epoxy powders, above two kinds of methods all can't realize.Than effective method is earlier steel strand wires to be opened coating, closes up after coating forms again.Because prestress wire belongs to high strength, underrelaxation material, open that steel wire can not have distortion in the process of closing up again, the lay pitch can not be changed, otherwise the mechanical property of steel strand wires can be influenced, this is the key issue that device for opening must solve.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of energy smooth opening is provided and closes up the steel strand parting and twisting device that prestress wire does not also have influence on the mechanical property of steel strand wires as far as possible.
The object of the present invention is achieved like this: a kind of steel strand parting and twisting device, comprise branch silk wheel and revolving drum, divide the silk wheel to be installed in the revolving drum, link to each other with revolving drum, divide on silk wheel center and the same circumference symmetric position to have a central hair hole and silk hole, six limits, as the passage of seven steel wires.
Seven steel wires of steel strand wires are passed seven branch silk holes after separately, and twisted again behind the traction certain distance is when steel strand wires are pulled forward; divide the silk wheel to rotate with the screw of steel wire; rotate in the same way by motor-driven revolving drum simultaneously, to reduce friction, the mechanical property of protection steel strand wires.When dividing a wheel to rotate the steel strand wires of back are opened, seven steel wires that simultaneously front passed through hole, branch center and branch silk hole are with speed ground twisted.Therefore, the present invention can smooth opening and is closed up prestress wire and do not have influence on the mechanical property of steel strand wires as far as possible.
Description of drawings:
Fig. 1 is a general structure schematic diagram of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the embodiments of the invention schematic diagram.
The specific embodiment:
Referring to Fig. 1～2, the present invention is a kind of steel strand parting and twisting device that seven prestress wires can be opened and do not damaged material.It mainly is made up of minute silk wheel 1 and revolving drum 2.
Revolving drum 2 is made up of cylindrical shell 2.1, cylindrical shell seat 2.2, little support roller 2.3, cylindrical shell slew gear 2.4 and bearing 2.5.Cylindrical shell 2.1 places in the cylindrical shell seat 2.2.Forward and backwardly on cylindrical shell 2.1 outside wall surface radially offer two support roller groove 2.1.1, be equipped with 2.3, three little support rollers 2.3 of three little support rollers in each support roller groove 2.1.1 and be symmetrically arranged in the cylindrical shell seat 2.2, fixedly connected with cylindrical shell seat 2.2.Like this, cylindrical shell 2 is by three little support roller 2.3 location of symmetric arrangement.Bearing 2.5 is embedded on cylindrical shell 2.1 internal faces.
Cylindrical shell 2.1 outer rims have a gear wheel 2.4.1, gear wheel 2.4.1 and carrier gear 2.4.2 engagement, and carrier gear 2.4.2 and pinion 2.4.3 engagement, pinion 2.4.3 is installed on the motor 2.4.4 output shaft, constitutes cylindrical shell slew gear 2.4 thus.Drive by torque motor, a suitable moment can be provided, overcome frictional force and steel strand wires twisted stress in the steel strand wires opening procedure, be unlikely to moment again and make the steel strand reversal rotational deformation too greatly.
Have a central hair hole 1.1 and silk hole, six limits 1.2 on the same circumference symmetric position of dividing silk to take turns 1 center and certain radius, as the passage of seven steel wires.In each silk hole, limit 1.2 ceramic-lined pipe 1.2.1 is housed, existing heat insulation effect has the effect that reduces to rub, prevent the steel wire scratch again.Silk hole, limit 1.2 can be calculated definite with the distance of opening device according to the lay pitch and required the closing up a little of steel strand wires with the distance in central hair hole 1.1.Divide silk wheel 1 to be installed in the cylindrical shell 2.1, link to each other with bearing.
Referring to Fig. 3, divide silk wheel 1 front side to be connected with devillicate disk 4 with connecting bolt 3, also have a central hair hole 4.1 and silk hole, six limits 4.2 on the same circumference symmetric position of devillicate disk 4 centers and certain radius, as the passage of seven steel wires.Seven steel wires of steel strand wires 5 are passed seven branch silk holes of branch silk wheel 1 and devillicate disk 4 after separately, twisted again behind the traction certain distance, steel strand wires are pulled time-division silk wheel energy passive rotation forward, motor drives the gear wheel rotation of cylindrical shell outer ring by pinion, carrier gear simultaneously, and the branch silk wheel that drives in simplified rotation and the cylindrical shell rotates.When dividing a wheel to rotate the steel strand wires of back are opened, seven steel wires that simultaneously front passed through hole, branch center and branch silk hole are with speed ground twisted.
