Abstract

The name of the utility model is copper bar flat-bending device which is processing equipment which flattens and curves copper bars. The utility model is to solve the problems that with the prior copper flat-bending device, the copper bar is easy to appear a crack or a fracture in the curving process, only a simple-shaped single-bending copper bar can be made instead of a complex-shaped copper bar which needs welding processing and has hidden dangers of accidents in the welding spot. The utility model is characterized in that the middle portion between a left guide pad and a right guide pad is provided with a terrace die which can move up and down, wherein the lower portion of the terrace die is provided with a corresponding cavity die, and the left guide pad, the right guide pad and the cavity die are fixed between a forward lateral plate and a backward lateral plate. The utility model makes best use of the plasticity and ductility of the copper bar, realizes the flattening and bending of the copper bar with a minor bend radius, selects different terrace dies and cavity dies, and produces various-shaped copper bar according to different requirements, thereby making the passing rate of the lead-out wires of a generator or the connecting wires of a distribution board reach to 100%.

Description

The flat curved device of copper bar

Technical field

The utility model relates to the flat curved process equipment of a kind of copper bar.

Background technology

The leading-out terminal of motor or the connecting line on the distribution board all need the copper strap wire of definite shape as bonding conductor, traditional flat curved device is mainly by 1 pressing plate, 1 handle and two flat curved wheels are formed, the course of work is that copper bar is inserted between two flat curved wheels, with pressing plate copper bar is fixed, driving handle, making handle center on the handle fulcrum rotates, flat curved wheel is with the flat curved certain angle of copper bar, because copper bar is carried out in the flat curved processing, copper bar one end is fixed, the other end floats, and copper bar is towards the distortion that is stretched of a direction under the effect of flat curved wheel, so the plasticity of copper bar itself and extensibility are not fully used, crackle appears when bending easily, even fracture, in order to prevent fracture and crackle, just need to increase the bending radius of copper bar, simultaneously, because the flat curved device structural limitations of tradition can only be processed the list of simple shape and bend copper bar, to then powerless than complex pattern; The producer that has for process adopt traditional flat curved device processing than the copper bar of complex pattern after, use welding processing again, as be used on the leading-out terminal of generator, then make each pole coil increase by two solder joints, every generator increases by 28 solder joints, the fault of generator is easily sent out has a little just increased by 28, thereby makes the fault probability of motor increase about 6%.

Summary of the invention

The purpose of this utility model is at above-mentioned deficiency, and a kind of plasticity of copper bar and the extensibility of making that proposes is fully used, and the bending radius of copper bar reaches minimum, can be according to the flat flat curved device of copper bar of bending the copper bar of various complicated shapes of different needs.

The technical solution of the utility model is: being provided with between left and right guide pad can upper and lower mobile punch, is provided with below punch and the corresponding die of punch, and left and right guide pad and die are fixed between the forward and backward side plate.

Said guide pad and die are fixed between the side plate of front and back with screw in the technical solutions of the utility model.

Said punch and die are formed V, S, shapes such as M, W in the technical solutions of the utility model.

Adopt the utility model that copper bar is floated in flat curved device, copper bar can be fully used the plasticity of copper bar itself and ductility towards both direction stretcher strain in flat curved process, realizes with the flat curved copper bar of less bending radius; In addition, can select different protruding, die for use, flatly bend difform copper bar according to different requirements; Thereby make the lead-out wire of generator or the connecting line qualification rate on the distribution board can reach 100%.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is a working state figure of the present utility model.

Embodiment

As Fig. 1, shown in 2, the flat curved device of copper bar is by punch 1 and die 4, and guide pad 2,3 constitute, punch 1 is located at guide pad 2, between 3, punch 1 can be on a left side, right guide pad 2, on between 3, move down, at punch 1 and guide pad 2,3 below is provided with and punch 1 corresponding die 4, punch 1, guide pad 2,3 and die 4 on a vertical plane, guide pad 2,3 and before die 4 usefulness screws 5 are fixed on, back side panel 6, location between 7, according to different requirements, can select for use different protruding, die 1,4, the shape of forming needs processing copper bar by punch 1 and die 4, as V, S, shape such as M or W, what provide among the figure is be processed into S shape copper strap wire protruding, die 1,4.

Operation principle: when needs worked copper lenticular wire, can select for use hydraulic press 10 as power, as shown in Figure 3, copper bar 9 is placed between punch 1 and the die 4, start hydraulic press 10, give punch 1 pressurization, punch 1 moves to die 4 directions under the effect of ambient pressure, and copper bar 9 slowly begins distortion, because copper bar 9 floats, can be towards left and right sides both direction stretcher strain, thus itself plasticity and ductility are fully used, when punch 1 moves to lower dead center, copper bar 9 bottoms contact fully with die 4 tops, copper bar 9 flat curved finishing.
