Abstract

The utility model relates to an electric power installing tool, in particular to a drawing wire bending device. The drawing wire bending device is characterized in that the drawing wire bending device is provided with two elongated press rods (3), the upper ends of the press rods (3) are hinged through a rotating shaft (4), a large pressing wheel (1) is installed on the rotating shaft (4), small pressing wheels (2) are respectively installed on the two press rods (3) through small shafts (5), the large pressing wheel (1) and peripheral wheel flanges of the small pressing wheels (2) are provided with recessed cambered surface grooves (6), and the groove (6) of the large pressing wheel (1) is opposite to the grooves (6) of the small pressing wheels (2). The drawing wire bending device has the advantages that a drawing wire is sent among the grooves of the large pressing wheel and the small pressing wheels and can be bent by wrenching the press rods, the bent drawing wire can be taken down by backswing of the press rods, the drawing wire bending device saves labor and is safe, convenient to operate and high in working efficiency, the drawing wire bending effect is good, the bending process is free of impact, the drawing wire and related fittings are free of damage, and the drawing wire bending device is simple in structure, low in fabricating cost, convenient to carry and suitable for electric power device installation and maintenance operation.

Description

Bracing wire pressing bender

Technical field

The utility model relates to a kind of power ampere holding tool, i.e. a kind of bracing wire pressing bender.

Background technology

In shop in erection of equipment and upkeep operation, often need the bracing wire higher some intensity to be converted into bending, past, owing to there is no specific purpose tool, can only impact and coordinate hand-power to carry out by hammer, rod, not only require great effort but also dangerous, and easily cause the damage of bracing wire and gold utensil, construction quality and progress are caused to negative effect.

Summary of the invention

The purpose of this utility model is to provide a kind ofly can carry out the bracing wire bending, and laborsaving, convenient, and the bending quality is good, and efficiency is high, can avoid bracing wire and gold utensil damage, guarantees the smooth and easy safe bracing wire pressing bender of construction.

Above-mentioned purpose is realized by following technical scheme: develop a kind of bracing wire pressing bender, be characterized in: two elongated depression bars are arranged, the depression bar upper end is by shaft hinge, large pinch roller is housed in rotating shaft, by little axle, little pinch roller is housed respectively on two depression bars, the peripheral rim of large pinch roller and little pinch roller is provided with the cambered surface groove of indent, and the groove of large pinch roller and little pinch roller is relative.

Said depression bar is provided with slotted hole, the little axle of little pinch roller is contained in slotted hole, and the slotted hole both sides are provided with many anti-skidding ribs, separately has the clamp of an end opening to be placed on above slotted hole, the little axle upper end of little pinch roller is provided with screw thread, and little axle matches with nut through the opening of slotted hole and clamp.

The beneficial effects of the utility model are: bracing wire is sent between the groove of big or small pinch roller, pull depression bar, bracing wire can be bent, the depression bar backswing, the bracing wire of press-bending can be taken off, laborsaving, safe, easy to operate, high efficiency, the bending quality of bracing wire is good, the bending process is without impact, bracing wire and relevant gold utensil not damaged, and simple in structure, cheap, be easy to carry, be suitable for the installation and maintenance operation of electric power facility.

The specific embodiment

The total design of the utility model is to complete the bending operation of bracing wire by lever and pinch roller.Below only exemplify one and execute example:

As shown in Figure 1 and Figure 2, this bracing wire pressing bender has two elongated depression bars 3, and large pinch roller 1, by rotating shaft 4 hinges, is equipped with in depression bar 3 upper ends in rotating shaft 4.By little axle 5, little pinch roller 2 is housed respectively on two depression bars 3, is provided with the cambered surface groove 6 of indent in conjunction with the peripheral rim of large pinch roller 1 and little pinch roller 2 shown in Fig. 3,4,5,6, the groove 6 of large pinch roller 1 and little pinch roller 2 is relative.In order to adapt to the bracing wire of different-diameter, the core wheel position of little pinch roller 2 can suitably be adjusted, concrete structure as shown in Figure 7, the axis hole that matches with little axle 5 on depression bar 3 is a slotted hole 7, little axle 5 can be in the slotted hole slide inside, there is screw thread little axle 5 upper ends, on definite position, with nut screwing clamping, get final product.In order to make the fixing more reliable of little axle 5, be provided with a plurality of anti-skidding ribs 8 on the depression bar surface of slotted hole 7 both sides, after nut screwing clamping, be difficult to mobile.If not enough fastening like this, can adopt the clamp 9 shown in Fig. 8, clamp 9 one end openings, both sides also can be provided with anti-skidding rib 8, be placed on slotted hole 7 above, the anti-skidding rib 8 on depression bar 3 and the anti-skidding rib 8 on clamp 9 are stuck, the little axle 5 of little pinch roller 2 is through the slotted hole 7 of depression bar 3 and the opening of clamp 9, lean against of clamp 9 openings, then with nut, that little axle 5 is fastening, little axle 5 just can not move to the hypomere of depression bar 3.During work, as shown in Figure 9, bracing wire one end that needs bending is injected between the groove 6 of large pinch roller 1 and little pinch roller 2, then pull depression bar 3 to both sides, can be by bracing wire 10 bendings.After completing bending, two depression bar 3 backswing are drawn close, bracing wire 10 can be extracted out.For all long bracing wires that is difficult to extraction of two ends, also can become flexible the clamp nut of little axle 5, little pinch roller 2 is retreated, and the increasing of the gap between large pinch roller 1, bracing wire 10 integral body can be shifted out.
