Abstract
The utility model discloses a bits device is prevented jumping by silicon steel sheet punching press, including a drift and complex doffer with it, doffer has the cylinder structure of vertically blanking passageway for inside, in the cylinder, the side of blanking passageway, and the side mouth that runs through downwards still communicates has a cavity that runs through downwards, the card is equipped with a propelling movement piece in the side mouth, the propelling movement piece is on one side towards the blanking passageway, a fixedly connected with direction stripper plate, the propelling movement piece is on one side towards the cavity, and the spring of fixing on the cavity inner wall is connected with the cavity through a plurality of. The utility model discloses the device structure is succinct ingenious, after the waste material was got into the blanking passageway by the drift punching press, the direction is dashed the layering and can be pushed down it the very first time under the effect of propelling movement piece and spring, lets this waste material can block on the passageway wall of perpendicular passageway promptly, makes it be difficult for again to be moved up by the quick reset of drift and moves the suction of formation and take to the higher authority to go, and the practicality is strong, is worth promoting.
Description
Technical Field
The utility model belongs to silicon steel sheet production field especially relates to a bits device is prevented jumping by silicon steel sheet punching press.
Background
In the prior art, in the production of silicon steel sheets, particularly in the punching and cutting of the silicon steel sheets, the problem of scrap jumping is easy to occur, particularly in the punching and cutting of small holes, punched waste materials are easy to reset quickly and move upwards to suck up again by a punch forming suction force, so that the punched waste materials fall onto silicon steel sheet plates which are not cut, the quality of punched holes is easy to influence or the surface of the silicon steel sheets is cut in the next punching process, the defective rate is increased, and people hope to find a simple and effective method to solve the problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a bits device is prevented jumping by silicon steel sheet punching press is provided.
The utility model discloses a realize through following technical scheme:
scrap jumping prevention device for punching of silicon steel sheets comprises a punch and a blanking device matched with the punch, wherein the blanking device is of a cylinder structure with a vertical blanking channel inside, a cavity penetrating downwards is further communicated with a side opening penetrating downwards in the cylinder and the side surface of the blanking channel, a pushing block is arranged in the side opening in a clamped mode and is arranged on one side facing the blanking channel and fixedly connected with a guiding extrusion plate, and the pushing block is connected with the cavity through a plurality of springs fixed on the inner wall of the cavity.
Preferably, the upper end of the guide extrusion plate is of an arc structure which is inclined outwards, and the guide extrusion plate is used for enabling the stamping waste to enter the blanking channel more smoothly.
Preferably, the punch is a punch with an arc edge, so that the punched waste has a circular butterfly-shaped plastic deformation, and the plastic deformation can be recovered and expanded, so that the waste is not easily brought to the upper side by the suction force formed by the rapid resetting and upward moving of the punch.
The utility model has the advantages that:
the utility model discloses a device structure is succinct ingenious, after the waste material is got into the blanking passageway by the drift punching press, the direction is punched the layering and can be pushed down it the very first time under the effect of propelling movement piece and spring, let this waste material block promptly on the passageway wall of perpendicular passageway, make it be difficult for again by the quick reset of drift shift up the suction of formation take to the higher authority go, then when this kind of waste material is accumulated to the certain degree in perpendicular passageway, can be through the extrusion with the waste material below extrude the slant passageway gradually in, accomplish incessant smooth and easy blanking, this kind of silicon steel sheet punching press is prevented jumping bits device greatly reduced the probability that the waste material was inhaled and is gone, the defective percentage has been reduced, the jumping bits has been prevented, the device itself makes easily, therefore, the clothes hanger is strong in practicability, and.
Drawings
For ease of illustration, the invention is described in detail by the following specific examples and figures.
Fig. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic structural view of a blanking device;
fig. 3 is a top view of fig. 2.
Detailed Description
As shown in fig. 1-3, the scrap-jumping-preventing device for stamping silicon steel sheets comprises a punch 1 and a blanking device 2 matched with the punch, wherein the blanking device 2 is of a cylinder structure with a vertical blanking channel 3 inside, a downward through cavity 4 is further communicated with a side opening in the cylinder and on the side surface of the blanking channel 3 through a downward through side opening, a pushing block 5 is clamped in the side opening, the pushing block 5 is fixedly connected with a guiding extrusion plate 6 on one side facing the blanking channel 3, and the pushing block 5 is connected with the cavity 4 through a plurality of springs 7 fixed on the inner wall of the cavity 4 on one side facing the cavity 4.
The upper end of the guide extrusion plate 6 is of an arc-shaped structure which is inclined outwards and used for enabling stamping waste to enter the blanking channel more smoothly.
The punch 1 is a punch with an edge provided with a radian, so that punched waste has a circular butterfly-shaped plastic deformation, and the waste can recover and expand after the plastic deformation, so that the waste is not easy to be brought to the upper side by a suction force formed by quick resetting and upward moving of the punch.
In operation, the blanking device is arranged below the lower stamping die 20, and after the silicon steel sheet raw material 10 is stamped by the punch 1, the waste material falls into the blanking channel 3 of the blanking device.
The utility model discloses a device structure is succinct ingenious, after the waste material is got into the blanking passageway by the drift punching press, the direction is punched the layering and can be pushed down it the very first time under the effect of propelling movement piece and spring, let this waste material block promptly on the passageway wall of perpendicular passageway, make it be difficult for again by the quick reset of drift shift up the suction of formation take to the higher authority go, then when this kind of waste material is accumulated to the certain degree in perpendicular passageway, can be through the extrusion with the waste material below extrude the slant passageway gradually in, accomplish incessant smooth and easy blanking, this kind of silicon steel sheet punching press is prevented jumping bits device greatly reduced the probability that the waste material was inhaled and is gone, the defective percentage has been reduced, the jumping bits has been prevented, the device itself makes easily, therefore, the clothes hanger is strong in practicability, and.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
