Detailed Description

Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some of the embodiments of the present application, but not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

In the description of the present application, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. For ease of description, the dimensions of the various features shown in the drawings are not drawn to actual scale. Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the specification where appropriate. In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

Example 1:

as shown in fig. 1, this embodiment provides a card punching cutter, which includes:

In the technical scheme, as shown in fig. 4, a punching cutter body is fixedly arranged on a machine tool, the punching cutter body is of a groove structure, the shape of the groove is the shape of a card after cutting, and sharp cutter bodies are arranged around the punching cutter body and are used for cutting the card; a card filling structure is fixedly arranged in the direction of the cutter body of the punching cutter on the machine tool, the structure is tightly attached to the cutter body of the punching cutter, the card filling structure is a bottomless cylindrical structure, and cards to be cut are filled in the middle; the machine tool is also provided with a stamping structure which is arranged on the other side of the card filling structure, wherein the stamping structure can drive to or from the card filling structure, and the stamping structure can apply external force to the card filling structure.

Before cutting the cards, driving the stamping structure away from the card filling structure, leaving a gap, and neatly filling the cards into the card filling structure; the stamping structure drives to the card filling structure, and the card in the card filling structure is pushed to the cutter body part of the stamping cutter and is pressed.

When the card is cut, the stamping structure is started, the stamping structure stably applies external force to the card filling structure, the card is pushed to move to the punching cutter body, and the card is cut under the action of the force.

The current die-cut sword has only a die-cut sword body, and when die-cut, the card slitter edge that is the frame shape can only break it through the external diameter of punching the cutter body, because the area of contact of cutter body is little, can form the condition that the card explodes the limit and explodes the angle at the in-process of cutting, causes the unnecessary loss of card, reduces the yield.

Therefore, the applicant adds an edge knife on the punching knife body, so that the contact area of the knife body and the card is increased, meanwhile, the force in the direction of the edge knife is increased, the card is not only subjected to the cutting pressure of the knife body of the punching knife body, but also subjected to the extrusion of the force in the direction of the edge knife, and the unnecessary part of the card is extruded by the force in the direction of the edge knife, so that when the card is punched and cut, the punching knife applies a transverse acting force to the unnecessary part to be cut of the card except for the force of the punching knife for circumferential cutting of the card, and the problem of edge explosion of the unnecessary part of the card is prevented from being caused outside the punching knife body at the moment of cutting.

Example 2:

the present embodiment provides a card punching cutter having the following technical features in addition to the technical scheme including the above embodiment.

As shown in fig. 1-3, in this embodiment, a threaded hole is formed on a side edge of the punching blade body, a mounting slot corresponding to the threaded hole is formed on the edge blade, and a fixing bolt for fixing the edge blade on the punching blade body is disposed between the mounting slot and the threaded hole.

In this technical scheme, through carrying out the screw thread trompil on die-cut sword body, be provided with the installation slotted hole on the limit sword, fix the limit sword on the die-cut sword body through fixing bolt, the unnecessary part of limit sword to the card applys external force, in the moment of cutting, the boundary part can not form great power, and then reduces the cutting part and get the edging condition.

In this embodiment, preferably, the mounting slot is a bar-shaped hole capable of adjusting the position of the edge cutter, and the width of the bar-shaped hole is the same as the outer diameter of the fixing bolt. The mounting slot holes are arranged to be of a strip-shaped structure, so that the position of the edge knife can be adjusted, and the edge knife can conveniently cut cards.

Example 3:

As shown in fig. 1 and 2, in this embodiment, a mounting plate is disposed on a side of the piercing cutter body, and the threaded hole is formed in the mounting plate. Regarding the die-cut sword body, in order to avoid directly seting up the screw hole on the die-cut sword body to lead to the intensity of punching the sword to reduce, can weld a mounting panel on the die-cut sword body for this reason, then seting up the screw hole on the mounting panel.

As shown in fig. 2 and 3, in this embodiment, the mounting end surface of the edge cutter is preferably serrated, and the mounting plate is matched with the mounting end surface of the edge cutter. In order to increase the friction force between the edge knife and the mounting plate and avoid the edge knife from sliding, the mounting end face of the edge knife is set into a saw-tooth shape, and the edge knife is provided with anti-skid stripes through the saw-tooth structure, so that the anti-skid effect is realized.

The embodiments of the present application and the features of the embodiments may be combined without conflict, and the present application is not limited to the specific embodiments described above, which are merely illustrative, not restrictive, and many forms may be made by those of ordinary skill in the art, without departing from the spirit of the present application and the scope of the claims, which are also within the protection of the present application.
