Abstract

The utility model relates to a bending shaped die on the wire leading terminal of the auxiliary pole coil of a motor, which comprises a die base which is provided with a slot. A coil fixing device which is composed of an end die block which is fixed at the bottom of the slot of the die base, and a die core block in the middle of the end die block, wherein, the end die block is provided with a wedge surface, and the coil fixing device is fixedly provided with a press plate. The utility model also comprises a primary bend die and a secondary bend die, wherein, the primary bend die is provided with a convex shaft which is arranged on a bent die which is arranged on the end surface of the primary bend die, and the primary bend die is fixed on the die base on the front part of the coil fixing device; the upper end surface of the secondary bend die is provided with a conductive wire clamping slot. The utility model also comprises a handle, wherein, the end part of the handle is provided with a shaft hole which is matched with the convex shaft on the primary bend mould, and the handle is fixedly provided with a bearing. The utility model provides a hand operated tool which directly canonically bends and shapes the wire leading terminals of the auxiliary pole coils of the motors, so that the wire leading terminals of the auxiliary pole coils of the motors can be directly bent to be shaped. The utility model overcomes the defect that the wire leading terminals which are bent to be shaped and are welded can easily loose weld existing in the existing method. The quality of the coils, the wire leading terminals of which are bent to be shaped by the utility model, conforms to the requests to the inspection.

Description

The lead end brake forming mould of the attached polar curve circle of motor

Technical field

The utility model relates to hand tool, is specially the lead end brake forming mould of the attached polar curve circle of motor.

Background technology

Two lead risers of the attached polar curve circle of motor need be to curving type, achieve a butt joint after making two lead riser brake formings, because the diameter of wire of the attached polar curve circle of motor is bigger, do not have specific purpose tool not flexible, prior art is earlier the lead riser of brake forming to be carried out, and adopts gas welding then, is welded on the lead end of attached polar curve circle with the yellow gold welding rod lead riser that brake forming is good, first, the operating procedure complexity, second, lead riser welding back is sealing-off easily.

Summary of the invention

The problem of the easy sealing-off that the lead riser elder generation moulding of the attached polar curve circle of the utility model solution motor, the prior art of back welding exist provides a kind of direct hand tool---lead end brake forming mould of the attached polar curve circle of motor that the lead end of attached polar curve circle is carried out brake forming.

The utility model is to adopt following technical scheme to realize: the lead end brake forming mould of the attached polar curve circle of motor, contain the mould base that has groove on it, in the groove of mould base, have by with the fixing end module that has wedge surface of the bottom land of mould base, the coil fixing device that core pieces in the middle of the end module is formed, on fixing device, be fixed with pressing plate, also contain on the mould base that can be fixed in coil fixing device front portion, on its upper surface bending die is arranged, elbow mould of protruding axle and the secondary elbow mould that there is the lead draw-in groove upper surface are arranged on the bending die, also contain handle, handle end has the axis hole that cooperates with protruding axle on elbow mould, also is fixed with bearing on handle.

The front end face of elbow mould and secondary elbow mould is a cylinder, and promptly first and second elbow mould is a cylinder with the end face that attached polar curve circle contacts, and is convenient to first and second elbow mould and cooperates with the position of coil.

The utility model provides a kind of hand tool that the lead end of the attached polar curve circle of motor is directly carried out the standard brake forming, can be with the direct brake forming of lead end of the attached polar curve circle of motor, overcome the defective of the easy sealing-off of welding manner after the existing first brake forming.The attached polar curve circle quality of lead end being carried out brake forming with this mould meets delivers for a check requirement.This mould structure advantages of simple, use easy to operate.

Embodiment

The lead end brake forming mould of the attached polar curve circle of motor, contain the mould base 2 that has groove 1 on it, in the groove of mould base, have by with the fixing end module 3 that has wedge surface of the bottom land of mould base, 4, the coil fixing device that core pieces 5 in the middle of the end module is formed, on fixing device, be fixed with pressing plate 6, also contain on the mould base that can be fixed in coil fixing device front portion, bending die 7 is arranged on its upper surface, elbow mould 9 of protruding axle 8 and the secondary elbow mould 11 that there is lead draw-in groove 10 upper surface are arranged on the bending die, also contain handle 12, handle end has the axis hole 13 that cooperates with protruding axle on elbow mould, also is fixed with bearing 14 on handle.The front end face of elbow mould 9 and secondary elbow mould 11 is a cylinder.

Mould base 2 is lain on the workbench, there is one of groove to face up,

end module

3,4 is placed in the groove of mould base, attached polar curve snare is gone into to hold module, core pieces 5 is pressed in the middle of the module of two ends then, pressing plate 6 is placed on coil and the coil fixing device and pressing plate 6,

end module

3,4 and mould base are fixed, thereby make coil location with bolt; Elbow mould 9 is put in the leading section of coil, and be screwed on the mould base by the fixedly ear at its two ends, handle 12 is fixed on the protruding axle of an elbow mould by the axis hole on it with nut, the lead end of coil is passed the groove that forms between bearing on the handle and the bending die on elbow mould upper surface, slowly inwardly move handle, lead end (bearing is rotatable, can reduce in the BENDING PROCESS wearing and tearing to coil lead) under the effect of the bearing on the handle realizes that along the bending die on elbow mould upper surface one time 90 inside degree of level is crooked; Withdraw from each assembly by assembling sequence,, use the same method another coil lead end is carried out first order buckling attached polar curve circle upset; Then, elbow mould and handle are unloaded, secondary elbow mould 11 is fixed on the mould base of coil leading section, lead end behind the first order buckling is snapped in the lead draw-in groove of secondary elbow mould upper surface, till knocking lead end to 90 degree downwards with wooden mallet, finish the second order buckling of downward 90 degree of lead riser, thereby finally finish the brake forming of coil lead end.Shape after the lead end brake forming is finished as shown in figure 13.
