Abstract
The utility model discloses a punching and blanking device which comprises a permanent seat, an upper film and a lower film which are respectively arranged at the upper part and the lower part of the permanent seat, a punching head which is fixedly arranged on the upper film, and a charging material which is pasted on the surface and at least one side surface of the lower film, wherein the charging material is provided with a punching hole which is matched with the punching head, the lower film is provided with a blanking hole, the shaft axis of which is overlapped with the shaft axis of the punching hole, and at least one side of the wall of the blanking hole is opened. When the waste material discharged from the punching hole falls into the blanking hole and blocks the blanking hole, the blocking waste material can be conveniently removed, and the problems that a die is easy to crack, the punching head is easy to rupture and the like due to the blockage of the blanking hole can be avoided, therefore, the maintenance cost of the die can be reduced, and the incidence rate of burrs of the product can be reduced.
Description
Technical field
The utility model relates to a kind of punching and blanking device, belongs to the punching die field.
Background technology
Hole punched device is widely used in Mould Machining.In the prior art, the punching and blanking device, comprise holder, be separately positioned on the patrix and the following film of holder upper and lower, be fixedly installed on the drift on the film, be sticked the surface of following film and at least one side surface go into son, go into and offer the punching that matches with drift on the son, offer the material-dropping hole that axial line overlaps with the axial line of punching on the following film, the hole wall of material-dropping hole is totally enclosed, when the waste material that punch process produces arrives material-dropping hole down, stop up not easy-clear of material-dropping hole, thereby influence working (machining) efficiency, and after long-time the use, die is easy to crack, and drift is easily broken.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of difficult obstruction material-dropping hole and easy-clear punching and blanking device are provided.
For solving above technical problem, the technical solution used in the present invention is: a kind of punching and blanking device, it comprises holder, be separately positioned on the patrix and the following film of holder upper and lower, be fixedly installed on drift on the film, be sticked the surface of film down and at least one side surface go into son, go into and offer the punching that matches with drift on the son, offer the material-dropping hole that axial line overlaps with the axial line of punching on the following film, it is open that the hole wall of material-dropping hole has one side at least.
Preferably, the diameter of material-dropping hole is more than or equal to the diameter of punching.
Preferably, punching and material-dropping hole all have a plurality of, and film is to distribute into the limit that son (5) covers under a plurality of material-dropping holes edge, and a plurality of punchings are corresponding one by one with a plurality of material-dropping holes.
Preferably, the width of the opening of the hole wall of material-dropping hole is 1/3～1/2 times of diameter of material-dropping hole.
The utility model compared with prior art has following advantage: when the waste material that punching is got off falls into material-dropping hole and stops up material-dropping hole, can remove the obstruction waste material easily, can prevent problems such as the die that is caused by the obstruction of material-dropping hole is easy to crack, drift easy fracture, thereby reduce the mold repair cost of upkeep, and also reduced the incidence of product burr.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Wherein: 1, holder; 2, patrix; 3, counterdie; 30, material-dropping hole; 4, drift; 5, go into son; 50, punching.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Punching and blanking device as shown in Figure 1, it comprises holder 1, be separately positioned on the patrix 2 and the following film 3 of holder 1 upper and lower, be fixedly installed on the drift 4 on the film 2, be sticked the surface of following film 3 and at least one side surface go into son 5, go on the son 5 and offer the punching 50 that matches with drift 4, offer the material-dropping hole 30 that axial line overlaps with the axial line of punching 50 on the following film 3, it is open that the hole wall of material-dropping hole 30 has one side at least, the diameter of material-dropping hole 30 is more than or equal to the diameter of punching 50, and the width of the opening of the hole wall of blanking 3 is 1/3～1/2 times of diameter of material-dropping hole 30.
Punching 50 and material-dropping hole 30 all have a plurality of and corresponding one by one, and film 3 is to distribute into the limits that son 5 covers under a plurality of material-dropping holes 30 edges.
So, when the waste material that punching is got off falls into material-dropping hole and stops up material-dropping hole, can remove the obstruction waste material easily, can prevent problems such as the die that is caused by the obstruction of material-dropping hole is easy to crack, drift easy fracture, thereby reduce the mold repair cost of upkeep, and also reduced the incidence of product burr.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
