Detailed Description
The present utility model will be described in detail below with reference to the embodiments shown in the drawings, but it should be understood that the embodiments are not limited to the utility model, and equivalent changes or substitutions of functions, methods or structures according to the embodiments by those skilled in the art are included in the scope of the present utility model.
In the description of the present utility model, it should be noted that, unless otherwise specified and defined, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, mechanically or electrically connected, may be in communication with each other between two elements, may be directly connected, or may be indirectly connected through an intermediate medium, and the specific meaning of the terms may be understood by those skilled in the art according to circumstances.
As shown in fig. 1, 2, 3 and 4, the cutting blade for the tin frame product on the side of the pin according to the present utility model comprises: mounting flange 1, cutter body 2, cutting edge 3 and abrasive grain layer 4, the outside fixed connection cutter body 2 of mounting flange 1, the outside of cutter body 2 sets up cutting edge 3, the outside cladding abrasive grain layer 4 of cutting edge 3, cutting edge 3 includes: the first cutting surface 31, the second cutting surface 32, the third cutting surface 33 and the fourth cutting surface 34, the first cutting surface 31 is arranged outside and parallel to the axial direction of the mounting flange 1, two ends of the first cutting surface 31 vertically extend the second cutting surface 32 towards the direction of the mounting flange 1, the second cutting surface 32 vertically extends the third cutting surface 33 towards two axial sides of the mounting flange 1, the end part provided with the third cutting surface 33 vertically extends the fourth cutting surface 34 towards the direction of the mounting flange 1, and the fourth cutting surface 34 is connected with the cutter body 2. By arranging the unique cutting edges 3 of the first cutting surface 31, the second cutting surface 32, the third cutting surface 33 and the fourth cutting surface 34, the product which needs to be cut for multiple times can be cut at one time directly, the production efficiency is improved, and the cutting precision is higher; the connection compatibility with cutting equipment is facilitated through the mounting flange 1; the tool life and cutting efficiency are improved by the abrasive grain layer 4.
The width of the first cutting surface 31 is 280um to 320um. The cutting of products of different specifications is facilitated through different cutting widths.
The third cutting face 33 has a width of 10um to 60um. The cutting of products of different specifications is facilitated through different cutting widths.
The sum of the lengths of the second cutting face 32 and the fourth cutting face 34 is 600um-1100um. The cutting of products of different specifications is facilitated through different cutting widths.
In the first cutting, steps are cut according to products of different specifications, and the groove width for increasing the contact area of the creeping tin is 300um-440um, so that the widths of the third cutting face 33 can be set according to different products; meanwhile, according to the different frames, the width of the groove to be cut is about 300um when the particles are required to be separated in the second cutting process, so that the width of the first cutting surface 31 is confirmed; the thickness of the product as a whole will not normally exceed 1000um, and the sum of the lengths of the second cutting face 32 and the fourth cutting face 34 is set in accordance with such data. Of course, the length settings of the second cutting face 32 and the fourth cutting face 34 are set for a particular product for different products.
The abrasive grain layer 4 covers the first cutting surface 31, the second cutting surface 32, the third cutting surface 33, the fourth cutting surface 34, and portions outside the cutter body 2. By utilizing the abrasive particle layers 4 with different concentrations, the service life of the cutter is prolonged, and the cutting efficiency is improved. Concentration refers to the volume fraction occupied by diamond (diamond) grit. For example, the concentration 100 represents 25% by volume of diamond (diamond) abrasive grains, and thus it is necessary to select the abrasive grain layer 4 having different concentrations according to the difference in the materials to be cut. The abrasive grain layer 4 having high concentration is required to be selected when the hardness of the material to be cut is high. The abrasive grain layer 4 is bonded to the cutting edge 3 by a resin or a metal, and the abrasive grain layer 4 is usually 5um to 10um thick.
A transition inclined plane 21 is arranged between the outer side of the cutter body 2 and the fourth cutting surface 34, and the thickness of the cutter body 2 is larger than that of the cutting edge 3 and the abrasive particle layer 4. The overall strength is improved by using the thicker cutter body 2, and meanwhile, the cutting edge 3 moves more stably in the high-speed cutting process, so that the serpentine moving state is reduced.
The thickness of the mounting flange 1 is smaller than the thickness of the cutter body 2. The existing cutting equipment is convenient to be compatible by arranging the aperture and the thickness of the mounting flange 1.
When the utility model cuts the tin wafer on the side surface of the pin, the first cutting surface 31 is contacted with the wafer and cuts, then the first cutting surface 31 and the second cutting surface 32 cut a first cutting groove on the metal frame, then the third cutting surface 33 continuously moves downwards until contacting with the top of the metal frame, and the second cutting surface 32 needs to cut less because the first cutting surface 31 has taken out part of the metal frame, the first cutting surface 31 continuously moves to the bottom of the metal frame while the third cutting surface 33 cuts until the metal frame and the plastic packaging material are cut off, and meanwhile, the third cutting surface 33 and the fourth cutting surface 34 cut wider grooves, thereby meeting the requirement of increasing the contact area of tin climbing. Through the arrangement, two working procedures can be completed by one cutting, and the theoretical improvement efficiency is one time higher than that of the original cutting blade, because the measurement and the position confirmation are required to be carried out during the second cutting, and the processing efficiency is greatly improved. Further, the machining can be completed at one time, so that the problem of workpiece deviation does not exist, and the machining precision is higher.
While only certain embodiments of the present utility model have been described, it will be apparent to those skilled in the art that other modifications and improvements can be made without departing from the inventive concept of the present utility model.
