Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Seeing Fig. 1 to Fig. 3, the T-shaped band punching press guide device of this utility model embodiment includes stripper 1 and die shoe 2,
The upper surface of die shoe 2 is provided with concave template 3, and stripper 1 can move up and down by concave template 3 relatively.Concave template 3 is provided with about two
Through die cavity 31 and at least one installing hole 32 of two die cavities 31 of connection, in the present embodiment, die shoe 2 is cuboid
Shape, two die cavities 31 are symmetrical about the central axis of die shoe 2.Concave template 3 is as the mould of T-shaped band 400.
The lateral wall of die cavity 31 is inclined-plane, and the lower ending opening of die cavity 31 is smaller in size than upper end open size, in die cavity 31
Be provided with location lift block 33, location lift block 33 lateral surface be the inclined-plane matched in the lateral wall with die cavity 31, medial surface with
The upper surface of die shoe 2 is vertical, here, the side that lateral surface is the central axis away from die shoe 2 of location lift block 33, fixed
The side that lateral surface is the central axis near die shoe 2 of position lift block 33.Flexible Reset parts 34 it are provided with in installing hole 32,
The two ends of Flexible Reset parts 34 elastic compression joint location lift block 33 respectively.In the present embodiment, lift block 33 upper end is positioned
Interior corner is arc angling.Arc angling is conducive to T-shaped band to avoid when punch forming in the thick material part of T-shaped band and thin material portion
The junction divided produces broken wound or produces burr, as shown in Figure 3.
Die shoe 2 is provided with the positioning through hole 21 corresponding with die cavity 31, is provided with material lift elastomeric element 22, lifts in positioning through hole 21
The upper end of material elastomeric element 22 is connected to location with the lower end elastic compression joint of location lift block 33, the lower end of material lift elastomeric element 22
In through hole 21, wherein, material lift elastomeric element 22 is lifting location lift block 33 under initial length, makes the upper table of location lift block 33
Face exceeds the upper surface of concave template 3.In the present embodiment, screw 23, packing ring 24 and plug screw 25, screw it are provided with in positioning through hole 21
23 through packing ring 24 lower end of stationary positioned lift block 33, and plug screw 25 is fixed on the bottom of positioning through hole 21, material lift elastic
The two ends of part 22 elastic compression joint screw 23 and plug screw 25 respectively.Alternatively, Flexible Reset parts 34 and material lift elastomeric element 22 are equal
For spring.Further, the diameter of packing ring 24 is more than the bore of die cavity 31.Material lift elastomeric element 22 positions lift block 33 in lifting
Time, packing ring 24 can be stuck in below die cavity 31, thus packing ring 24 can play position-limiting action, makes location lift block 33 to increase specific
Height.
The T-shaped band punching press guide device of this utility model embodiment operationally, when stripper 3 moves downward, stripper 3
The T-shaped band of punching press, and then location lift block 33 is pressed downward against until the upper surface of the upper surface and concave template 3 that position lift block 33 is put down
Together.Owing to the sidewall of die cavity 31 is inclined-plane, location lift block 33 is during pressure down, and Flexible Reset parts 34 can be compressed,
The distance between the lift block 33 of location in two die cavities 31 can diminish, it is achieved thereby that determine T-shaped tape thickness material portion
Position.After punching press completes, stripper 3 moves upward, and location lift block 33 is upwards lifted under the elastic force effect of material lift elastomeric element 22
Rising, owing to the sidewall of die cavity 31 is inclined-plane, the location lift block 33 in two die cavities 31 is under the effect of Flexible Reset parts 34
Distance can become big, so that with the thick of T-shaped band, the interior corner of location lift block 33 expects that part produces certain interval, is possible to prevent
The side of T-shaped tape thickness material part produces broken wound.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize equivalent structure or equivalence flow process conversion that this utility model description and accompanying drawing content made, or be directly or indirectly used in
Other relevant technical fields, are the most in like manner included in scope of patent protection of the present utility model.
