Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1, an embodiment of the present invention provides a blanking apparatus for blanking a material to be cut, including: a base 1 for placing the material to be cut 11; a blade 22 disposed above the material to be cut 11; and the punching mechanism 3 is arranged above the cutting tool 22 and is used for applying punching force to the cutting tool 22 so as to enable the cutting tool 22 to move downwards and punch the material 11 to be cut.

When the blanking equipment is used for processing a material to be cut, the material to be cut is placed on the base, the cutting tool is placed above the material to be cut, and a stamping force is applied to the cutting tool through the stamping mechanism, so that the cutting tool moves downwards and the material to be cut is blanked, and the material to be cut is processed.

Specifically, when the material to be cut is placed on the base, the reference plane part of the base is used as a positioning reference, and the reference plane of the eccentric rotary part is kept in contact with the reference plane of the base, so that the rotary center of the part to be machined on the material to be cut is enabled to be coincident with the rotary center of the main shaft of the stamping mechanism.

It will be appreciated that in order to achieve processing of the material to be cut, it should be ensured that the edge of the cutting tool is completely inside the edge of the material to be cut when the material to be cut is placed.

In some embodiments, the cutting apparatus described herein, the blade 22 is a circular ring blade. When the parts to be processed and formed are sealing pad parts, a circular cutting tool can be adopted. Specifically, the circular cutting tool moves downwards under the driving of the punching mechanism, so that circular parts are directly punched on the material to be cut. The embodiment omits the process of cutting the material to be cut along the inner and outer shape lines respectively in the prior art, can process and form the sealing pad parts at one time, has high forming efficiency, omits the step of manual cutting, and has high forming precision.

As shown in fig. 2, in some embodiments, in the blanking apparatus, the cutting tool 22 includes an inner blade 222 and an outer blade 221, the inner blade 222 and the outer blade 221 are both circular, and the outer blade 221 is sleeved outside the inner blade 222, so as to form a circular cutting tool with the inner blade 222.

Specifically, the circular cutting tool moves downwards under the driving of the punching mechanism, and the inner blade 222 and the outer blade 221 simultaneously cut the material to be cut, so that the sealing pad type part is processed at one time.

In some embodiments, the blanking apparatus is described in which the blade 22 is mounted on a mounting plate 21.

The sharps 22 are mounted to the mounting plate 21 to form a single sharps unit 2. When the material to be cut needs to be processed, the cutting tool component 2 is placed on the material to be cut 11; when the machining is completed, the blade assembly 2 can be removed directly. That is, based on the blade assembly, the forming process for the material to be cut can be simplified. Moreover, various cutting tool assemblies can be designed, and then the cutting tool assembly with the proper shape and size is selected to process the material to be cut according to the shape and size of the processed part.

In some embodiments, in the blanking apparatus, the mounting plate 21 is formed with two circular grooves, and the inner blade 222 and the outer blade 221 are respectively inserted into the two circular grooves. In particular, the inner and outer blades may be secured within the circular recess by super glue.

In some embodiments, in the blanking apparatus, the punching mechanism 3 includes a press 32 and a punching plate 31 connected to the press 32, wherein the press 32 drives the punching plate 31 to move downward or upward, thereby switching the punching plate 31 and the mounting plate 21 between a state of contacting with or releasing from each other.

Specifically, in a state where the press 32 is not operated, there is no contact between the punch plate 31 and the mounting plate 21. The material 11 to be cut is placed on the base 1 and then the blade assembly 2 is placed on top of the material 11 to be cut. Then, the press 32 is started, the press 32 drives the punching plate 21 to move downwards, the punching plate 31 and the mounting plate 21 contact with each other, the punching force is continuously applied to the mounting plate 21, and the cutting tool 22 moves downwards to punch the material to be cut 11, so that the part is machined and formed. The press 32 then drives the punch plate 31 upwardly and the punch plate 31 and mounting plate 21 are disengaged from one another, at which point the blade assembly 2 can be removed and the formed part removed. Then, the material to be cut can be adjusted, and the unprocessed part is continuously processed and molded, so that the serialized production process of the part is realized.

In some embodiments, the press 32 is a spinning press in the blanking apparatus.

In some embodiments, in the blanking apparatus, the material to be blanked 11 is a non-metal soft material.

In some embodiments, the material to be cut 11 is a rubber material in the blanking apparatus.

In summary, based on the blanking device, the forming efficiency of the material to be cut can be improved, and the forming precision can be improved, namely, a fast, accurate and efficient blanking forming method is provided.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make variations and modifications without departing from the spirit and scope of the present invention.
