Abstract
The utility model discloses groove profile commutator segment section bar, it is characterised in that：Transverse section of section material has bilateral symmetry, left groove profile commutator segment is formed after the punching of left side, right groove profile commutator segment is formed after right side punching, left and right groove profile commutator segment has identical structure and shape, plane where left groove profile commutator segment bonding wire step lateral surface and plane where right groove profile commutator segment bonding wire step lateral surface, connect before punching connected, the section bar upper and lower surface for the connecting place that connects sets circular arc chamfering.The utility model can save commutator segment and manufacture required material cost, and is not required to after punching flash removed and can be directly used in screening process, improve commutator production efficiency.
Description
Technical field
It the utility model is related to commutator topology field, and in particular to one kind is used to manufacture reversing sheet of groove-type reverser
Groove profile commutator segment section bar.
Background technology
Tank commutator, because the top of its groove profile commutator segment generally carries bonding wire step, typically it is of an L-shaped structure, L
The commutator segment of type structure needs to expend more material in blanking process.At present, it is to reduce waste of material, also has by using changing
Made to the mode of piece optimization arrangement to carry out the punching of commutator segment, but the requirement of commutator segment section bar is higher, and punching surplus is larger,
Further, the commutator segment after punching needs to be removed burr work, follow-up commutator segment screening process not so can be influenceed, because such as
The jagged presence of fruit, gap cannot be effectively ensured between the piece of commutator segment, therefore the production efficiency of commutator is relatively low.
The content of the invention
In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to be that commutation can be saved by providing one kind
Piece manufactures required material cost, and is not required to after punching flash removed and can be directly used in screening process, improves commutation
The groove profile commutator segment section bar of device production efficiency.
The utility model is implemented by the following technical programs：
Groove profile commutator segment section bar, it is characterised in that：Transverse section of section material has bilateral symmetry, is formed after the punching of left side
Left groove profile commutator segment, right side form right groove profile commutator segment after being punched, and left and right groove profile commutator segment has identical structure and shape,
Plane where left groove profile commutator segment bonding wire step lateral surface and plane where right groove profile commutator segment bonding wire step lateral surface, are being punched
Before connect connected, the section bar upper and lower surface of the connecting place that connects sets circular arc chamfering.
The groove profile commutator segment section bar of above-mentioned technical proposal, using the bilateral symmetry of optimization design, after the punching of left side
Left groove profile commutator segment is formed, right groove profile commutator segment, and left groove profile commutator segment bonding wire step lateral surface are formed after right side punching
Place plane connects before punching with plane where right groove profile commutator segment bonding wire step lateral surface and is connected, so can be farthest
Punching surplus is reduced, commutator segment is saved and manufactures required material cost；In addition, section bar upper and lower surface is changed in left and right groove profile
Flat face connecting place sets circular arc chamfering where to piece bonding wire step lateral surface, even if such groove profile commutator segment stays after punching
It is jagged, the screening of commutator segment is not interfered with yet, therefore be not required to flash removed after punching to be directly used in screening process, carry
High commutator production efficiency.
The radius of the circular arc chamfering is 0.8mm, depth 0.3mm.
Plane where left groove profile commutator segment bonding wire step side and plane where right groove profile commutator segment bonding wire step side,
Anteposition is punched in same level.
Brief description of the drawings
The utility model has the following drawings：
Fig. 1 is the viewgraph of cross-section of groove profile commutator segment section bar；
Fig. 2 is schematic diagram of the groove profile commutator segment section bar after punching.
Embodiment
As illustrated, groove profile commutator segment section bar of the present utility model, transverse section of section material have bilateral symmetry, left side
Left groove profile commutator segment 1 is formed after punching, forms right groove profile commutator segment 2 after right side punching, left and right groove profile commutator segment has identical
Structure and shape, plane 8 where the left lateral surface of 1 bonding wire step of groove profile commutator segment 3 with outside the right bonding wire step 4 of groove profile commutator segment 2
Plane 9 where side, connects connected before punching, and the section bar upper and lower surface for the connecting place that connects sets circular arc chamfering 5, the circular arc
The radius of chamfering 5 is 0.8mm, depth 0.3mm；Plane 6 where the left side of 1 bonding wire step of groove profile commutator segment 3, is changed with right groove profile
Plane 7 where to the side of 2 bonding wire step of piece 4, in punching anteposition in same level.
