Abstract
The utility model discloses a kind of waste material cut-off knife group, comprise the first cutter hub, the second cutter hub, knife rest.First cutter hub, the second cutter hub are all vertically mounted on knife rest, and the bottom of the first cutter hub, the second cutter hub is connected with knife rest.The spacing distance of the adjacent surface of the first cutter hub of the present utility model and the second cutter hub, from top to down, change from small to big, and then make the waste material section after cutting must be less than both spacing distances, can not get stuck, the phenomenon of bridging, two proximal surfaces of cutter hub are two sides design simultaneously, make the structural strength of its edge of a knife part higher, increase the durability of cutter hub.
Description
Technical field
The utility model relates to the process of stampings, a kind ofly specifically the waste material after punching press can be cut into three sections, to facilitate waste material from the cut-off knife group of waste material way discharging device.
Background technology
In punch process, there will be waste material, when waste material is excessive, after often needing to be cut into several sections, segmentation is discharged.Present waste material cut-off knife, identical with common cutter structure, front end is tapered specifically, utilizes the stampings plate face, front end of taper, completes and cut.The cut-off knife of this kind of structure, waste material only need to cut into two sections can send time, and no problem, but when waste material need to cut into three sections of ability send smoothly time, needs two, cutter fit in a cutter group, adopt the cutter group of said structure knife combination just to there will be drawback.Specifically, as described in Figure 1, because two cutter tapered front end coordinate, make cutter spacing, up big and down small, the waste material cut out is larger than the discharging clearance between cutter, stage casing waste material usually can be stuck between two cuttves, can not must discharge smoothly.
Summary of the invention
The purpose of this utility model is to overcome the deficiency existing for traditional waste material cut-off knife group, provides a kind of waste material cut-off knife group that can meet the smooth discharging of stage casing waste material.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of waste material cut-off knife group, comprises the first cutter hub, the second cutter hub, knife rest.First cutter hub, the second cutter hub are all vertically mounted on knife rest, and the bottom of the first cutter hub, the second cutter hub is connected with knife rest; First cutter hub is in long block, and its left side is vertical plane, is inclined-plane above; It is 125 degree with the angle on the left side above; The right side comprises with the first surface be connected and lower than second of first surface above; First surface and the second face are vertical plane, first surface and second curved transition in junction; Coordinate with first surface above and form the edge of a knife; Second cutter hub is in long block, and its right side is vertical parallel, is inclined-plane above; Be 125 degree with the angle on the right side above, the left side comprises with the first surface be connected and lower than second of first surface above; First surface and the second face are vertical plane, the curved transition in junction of first surface and second.
The spacing distance of the adjacent surface of the first cutter hub of the present utility model and the second cutter hub, from top to down, change from small to big, and then make the waste material section after cutting must be less than both spacing distances, can not get stuck, the phenomenon of bridging, two proximal surfaces of cutter hub are two sides design simultaneously, make the structural strength of its edge of a knife part higher, increase the durability of cutter hub.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional cut-off knife cutter group.
Fig. 2 is structural representation of the present utility model.
In figure, each label is respectively:
Above (1) first cutter hub, (2) second cutter hubs, (3) knife rest, (101) left side, (102), (103) first surface, (104) second, (201) right side, (202) second, above (203), (204) first surface.
Detailed description of the invention
Further understand for convenience of doing the utility model, existing by reference to the accompanying drawings for an embodiment, the utility model is further described.
Embodiment:
As shown in Figure 2, the utility model comprises the first cutter hub 1, second cutter hub 2, knife rest 3.First cutter hub 1, second cutter hub 2 is all vertically mounted on knife rest 3, and the bottom of the first cutter hub 1, second cutter hub 2 is connected with knife rest 3;
First cutter hub 1 is in long block, and its left side 101 is vertical plane, above 102 be inclined-plane; 102 is 125 degree with the angle on the left side 101 above; The right side comprises and 102 first surfaces be connected 103 and the second face 104 lower than first surface 103 above; First surface 103 and the second face 104 are vertical plane, first surface 103 and the second curved transition in junction, face 104; 102 to coordinate with first surface 103 and form the edge of a knife above;
Second cutter hub 2 is in long block, and its right side 201 is vertical parallel, above 203 be inclined-plane; 203 is 125 degree with the angle on the right side 201 above, and the left side comprises and 203 first surfaces be connected 204 and the second face 202 lower than first surface 204 above; First surface 204 and the second face 202 are vertical plane, the curved transition in junction in first surface 204 and the second face 202.
