Abstract
The utility model discloses a commutator segment die, which comprises a die shank, an upper die fixing plate, a punch head fixing plate, a punch head, a lower die plate and a bottom plate, and is characterized in that: an upper row and a lower row of symmetrical die holes staggered fore and aft are arranged on the lower die plate, and middle die holes are arranged in the middle of the two rows of die holes. The utility model can effectively reduce the production cost of the commutator segment.
Description
[technical field]
The utility model relates to a kind of diel, and what be specifically related to is a kind of improvement invention of commutator commutator segment punch die.
[background technology]
At present, punch die generally is the single punching press of carrying out when punching press commutator commutator segment, the width of strip is a bit larger tham the width dimensions of commutator commutator segment, each commutator segment of punching production, the strip after the punching press can produce more loss like this, and the production cost of commutator commutator segment is higher.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of commutator commutator segment punch die that reduces commutator commutator segment production cost.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
Commutator commutator segment punch die comprises die shank, upper mould fixed plate, drift fixed head, drift, lower bolster and base plate, it is characterized in that: described lower bolster is provided with the nib that two rows are symmetrical and stagger in front and back, is provided with middle nib in the middle of two row's nibs.
Punching press by above-mentioned punch die, under the prerequisite of using the specific width strip (greater than the width of a commutator commutator segment, width less than two commutator commutator segments), can stamp out two side by side commutator commutator segments up and down at every turn, stagger in two relative up and down also front and back of commutator commutator segment, can be mutually between the front and back commutator commutator segment after each punching press near, so, relative each commutator commutator segment, the loss that its strip produces just can reduce, and promptly effectively reduces commutator commutator segment production cost.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the vertical view of lower bolster among Fig. 1
Fig. 3 is the stock layout figure of the commutator commutator segment of the utility model institute punching press
Fig. 4 is the stock layout figure of the commutator commutator segment of prior art institute punching press
[specific embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and operation principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1, commutator commutator segment punch die of the present utility model comprises die shank 8, upper mould fixed plate 9, drift fixed head 10, drift 11, lower bolster 12 and base plate 13; With reference to accompanying drawing 2, described lower bolster 12 is provided with nib 1,2,3, middle nib 4,5 and the nib 6,7 that two rows are symmetrical and stagger in front and back, the commutator commutator segment stock layout figure of above-mentioned punch die institute punching press as shown in Figure 3, relatively can obviously find out with the stock layout figure of the commutator commutator segment of prior art institute punching press among Fig. 4, the loss that strip produces obviously reduces, and promptly effectively reduces commutator commutator segment production cost.
