Abstract
The utility model relates to a bending tool for copper bar leading wires, which is characterized by comprising an upper mould block and a lower mould block respectively fixed on an upper working platform and a lower working platform of an oil press, and a structure for clamping and positioning the leading wires. Matching surfaces consistent with the shapes of the bent leading wires are arranged on the upper mould block and the lower mould block. The structure for clamping and positioning comprises a first support frame fixed on the lower working platform of the oil press, a second support frame fixed on a working platform dedicated for pole coils, and pressure plates arranged on the two support frames, and the upper end of the first support frame and that of the second support frame are positioned in the same plane. The structure for clamping and positioning further comprises a positioning plate used for limiting the end parts of the leading wires. By adopting the tool to bend the copper bar leading wires, the upper leading wire and the lower leading wire of the rotor pole coil are consistent, so that the position and pitch errors of the two leading wires are reduced to be within the designed range, meanwhile, the forming techniques of the rotor pole coil is altered and optimized. First of all, scribing, perforation, tin coating, and bending are performed on the copper bar leading wires; at last, the welding and the forming of the rotor pole coil are realized on a four-corner magnetic pole welder.
Description
Technical field
The utility model relates to the lead-in wire press-bending processing and fabricating technical field of rotor four fillet welding pole coils, particularly a kind of copper bar lead-in wire press-bending frock.
Background technology
At present, the moulding process of rotor four fillet welding pole coils is: assembly welding rotor magnetic pole coil on four jiaos of magnetic pole welding machines, comprise the welding of lead portion, and on lead-in wire, rule, punch, ward off tin then, press-bending at last goes between.The rotor magnetic pole coil that adopts above-mentioned technological forming is when the press-bending operation, need pole coil be lifted on overhead traveling crane and carry out upper and lower lead-in wire press-bending on 100 tons of hydraulic presses, because the volume and weight of coil is bigger, on hydraulic press, adjust and locate relatively effort, coil often occurring puts not in place, cause the position and the pitch-row error of back pole coil two lead-in wires that bend bigger, under the serious situation, can not satisfy the designing requirement of drawing.With the pole line snare of above-mentioned bent into shape extremely after, will influence the assembly quality of pole coil lead and interpolar connecting line.
Summary of the invention
The utility model provides a kind of compact conformation, change and optimization rotor magnetic pole coil molding technology for solving the technical problem that exists in the known technology, guarantees the press-bending frock of the copper bar lead-in wire of lead-in wire press-bending quality.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of press-bending frock of copper bar lead-in wire is characterized in that: comprise the lower module that is fixed on the hydraulic press lower table, the upper module that is fixed on the hydraulic press upper table reaches the structure of the copper bar lead-in wire being carried out clamping and positioning; Described upper and lower module is provided with and the consistent mating surface of back shape that bends that goes between; Described clamping and positioning structure comprises first bracing frame that is fixed on the hydraulic press lower table, be fixed in second bracing frame on the pole coil dedicated, be arranged at the pressing plate of first bracing frame and second bracing frame upper end, the upper end of described first bracing frame and second bracing frame is positioned at same plane, and described clamping and positioning structure also comprises carries out spacing location-plate to the end of lead-in wire.
The technical scheme that the utility model can also be taked is:
The bottom of described lower module is welded with lower shoe, four jiaos of described lower shoe are provided with the elongated slot that matches with dovetail groove on the hydraulic press lower table, the bottom of described upper module is welded with upper plate, and four jiaos of described upper plate are provided with the elongated slot that matches with dovetail groove on the hydraulic press upper table; The described location-plate that the end of lead-in wire is limited to is fixed on the lower shoe.
Advantage and the good effect that the utlity model has are:
By adopting the copper bar lead-in wire is bent by the upper and lower module and the clamping and positioning structure that are fixed on the hydraulic press workbench, the upper and lower lead-in wire of rotor magnetic pole coil is consistent, reduce two positions that go between and pitch-row error in scope of design, changed and optimized the moulding process of rotor magnetic pole coil simultaneously: at first tin and press-bending are rule, punch, warded off to the copper bar lead-in wire, the last welding fabrication of on four jiaos of magnetic pole welding machines, realizing the rotor magnetic pole coil.
