Abstract

A bender for copper-coated aluminum wires comprises a clamp plate and a bending clamp plate. The clamp plate and the bending clamp plate are mounted in a stacked manner by the aid of a center shaft, one end of the center shaft is fixed onto the axis of the clamp plate, the other end of the center shaft is sleeved with threads and provided with a corresponding butterfly nut, and a washer is disposed between the butterfly nut and the bending clamp plate. The bender is characterized in that fixing rolling shafts are respectively arranged at corresponding positions of the clamp plate and the bending clamp plate, rolling sleeves are disposed on outsides of the rolling shafts, and the fixing rolling shafts are mounted oppositely. By the aid of the bender, friction of the copper-coated aluminum wires can be reduced, breakage and burring of the surface of a composite guide wire are prevented, the composite guide wire cannot be damaged easily during bending and is stressed uniformly, bending quality of the composite guide wire can be guaranteed, guide wires with different sections can be processed and can be bent into different angles on the bender, and processing quality is also guaranteed.

Description

Copper Clad Aluminum Wei bender

Technical field

The utility model relates to a bender Wei, Wei is a particular bent copper clad aluminum conductor composite special tools.

Background technology

Copper cover aluminum composite wire rod and copper cash are different, and pure copper wire is to include only a kind of material, and copper-coated aluminum complex lead matrix to be the aluminium outer surface coat certain thickness copper layer, add man-hour tensile strength with extend rule performance and fine copper lead certain gap arranged.The local compression strength of copper cover aluminum composite conductor will be lower than the fine copper lead, and when outer surface received equal external impacts, the distortion of copper layer was bigger; In distortion, matrix changes thereupon, the geometry of copper-clad aluminum conductor; Size with outer active force changes, and is because the performance of copper layer endobasal-body materials of aluminum is lower than copper, does not have enough intensity to support the copper layer; Copper and aluminium can keep the good binding state, satisfy instructions for use but under certain condition.

Currently, electrical equipment manufacturing and coil winding wire Wei often encountered during bending operations, due to the limitations of existing Wei bending tool, Wei bend ineffective, thereby affecting the overall product quality.Analysis found that wire Wei bending operation appears on the quality defect is due Wei bend tool works on its structure design or inadequate, such as wire break or wrinkle, from the thorn is due to the tool axis of the wire , the wire between the contact surfaces of the tool and the sliding friction occurs during bending Wei different locations and sizes of wires are not properly positioned securely clamping caused.So the traditional tools Wei Wei bend copper clad aluminum composite wire bend easily when the composite wire broken or wrinkled, from the thorn.Especially for the different sections of copper clad aluminum composite wire, you need to Wei bend at different angles, but also to ensure the quality, use a tool to achieve the existence of technical difficulty.

The utility model content

The utility model technical problem to be solved is to provide a copper-clad aluminum wire Wei bender, so that the copper clad aluminum composite wire can be bent to the desired angle as required Wei and prevent Wei bend fracture, from the thorn and other undesirable phenomena occurred, and to ensure smooth transition and with the corner arc consistent.

To solve the above problems, the present utility model technical solution adopted is one kind of copper clad aluminum wire Wei bender, which consists of curved plywood and plywood stacked form through the central axis, the axis splint axis fixed at one end, the other end sleeve wire, there is a corresponding wing nuts, wing nuts and washers between the curved plywood; their plywood and bent plywood axis, respectively, with the corresponding position fixing roller, roller external set the scroll sets, fixed roller mounting direction relative.

The copper-clad aluminum wire Wei bender, and a fixed set of rollers and rolling gap with the contact surface roughness of less than 3.2.

The utility model Wei copper clad aluminum wire bender, and a fixed scroll roller sets installed in the Wei bend, because sets can be rotated to reduce friction with the copper clad aluminum wire, to ensure the composite wire surface is not damaged, since spines.Wei bend all the parts have to undergo a finishing tool, each axis, each of the sets of machining accuracy of surface roughness 3.2.Cover is high-precision gap with cooperating of axle and cooperates, and the assurance rotation precision is good, easy damaged compound wire not during bending; And it is stressed even; Fine finishining is all carried out with grinding machine in clamping plate and angle coupling plate surface, and the depth of parallelism after assurance flatness, plane precision and the assembling makes compound copper-aluminium wire stressed evenly.The application of these measures greatly improved curved copper clad aluminum wire Wei's performance to ensure that the quality of the composite conductor Wei bending, reaching tool can be processed in a different section of the wire, Wei made from different angles, but also to ensure processing quality purposes.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the A of Fig. 1---the cutaway view of A part;

Fig. 3 is the B of Fig. 1---the cutaway view of B part.

The specific embodiment

Shown in Figure 1, the copper-clad aluminum wire Wei bender, by the band handle a bent plywood and plywood 2 3 4 stacked constituted through the central axis, the central axis 4 plywood 3 axis fixed at one end and the other end of the wire sets, and the corresponding sets of silk butterfly nut 6 with curved plywood between two washer 5.Can see that from Fig. 2 and Fig. 3 clamping plate 3 and angle coupling plate 2 relevant positions are respectively equipped with

fixed roller

8 and 9, its installation direction is relative, and roller bearing 8 and 9 outside are equipped with the

cover

7 and 10 that rolls respectively.

Above Wei bender, their parts used in all 304 stainless steel, while the existing old Wei bending tool uses ordinary steel materials.Ordinary steel surface is easy to rust, easy to bend in Wei aluminum composite conductors resulting in "pollution", thus affecting the quality of products.

Shown in Figure 2, the above-described fixing roller bender Wei retrofitting roll sets 8 7, in the Wei bend, as set 7 is rotatable, reducing the fixing roller 8 and the aluminum composite wire friction, guarantee composite wire surface is not damaged, from the thorn.

Meanwhile, the composition of the Wei bender all the parts have to undergo finishing.Every axle, each cover requirement on machining accuracy are that surface roughness is not more than 3.2.Cover 7 is the matched in clearance that meets required precision with cooperating of axle 8, guarantees that rotation precision is good.Easy damaged compound wire not during bending, and stressed evenly fine finishining is all carried out with grinding machine in clamping plate 3 and angle coupling plate 2 surfaces to guarantee the depth of parallelism after flatness, plane precision and the assembling, makes copper-coated aluminum complex lead stressed evenly.
