Technical Field

[0001] This invention relates to a cutting mechanism for the mid-plate of an ultra-thin smartphone, and relates to the field of precision parts processing technology. Background Technology

[0002] The interaction and changing laws between the cutting tool and the workpiece during metal cutting are a discipline in themselves. When designing machine tools and cutting tools, formulating cutting processes and quotas for machine parts, rationally using cutting tools and machine tools, and controlling the cutting process, we must utilize the research results of metal cutting principles to achieve the goals of economical, high-quality, and high-efficiency machining of machine parts.

[0003] In the existing technology, when machining workpieces of various thicknesses, it is often necessary to precisely adjust the tool stroke, which requires frequent tool stroke settings, which is time-consuming and labor-intensive. In addition, burrs that are difficult to grind are generated on the edge of the workpiece during the cutting process, which leads to frequent machine adjustments and tool changes during the machining process, making the program complex and difficult to operate. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting mechanism for the mid-plate of an ultra-thin smartphone. This cutting mechanism can process workpieces of various thicknesses without adjusting the tool stroke when processing workpieces of different thicknesses, thereby improving production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a cutting mechanism for the mid-plate of an ultra-thin smartphone, comprising: a first tool group and a second tool group arranged opposite to each other, a workpiece disposed between the first tool group and the second tool group, each of the first tool group and the second tool group comprising a tool holder, a tool neck, a blade and a cutting edge, the tool neck being fixedly disposed below the tool holder, the blade being located on the lower surface of the tool neck, the cutting edge being disposed at the outer edge of the blade, the tool holder being fixed by a tool holder, and the tool holder being connected to a drive mechanism;

[0006] The upper surface of the blade of the first tool set and the lower surface of the blade of the second tool set are staggered. The edge of the blade of the first tool set is an inwardly inclined slope. The blade of the second tool set is composed of four cutting parts of the same shape spliced ​​together. The cutting part is provided with a cutting edge at the end and has an outwardly protruding arc part at the end of the cutting part, thereby forming a triangular connecting part on the workpiece between the blades of the first tool set and the blades of the second tool set. The lower part of the blade holder connected to the blade neck is shaped like an inverted frustum.

[0007] The following are further improvements to the above technical solution:

[0008] 1. In the above scheme, the tool holder has a mounting through hole in the center, and several screw holes are opened on the side surface of the tool holder. The tool handle is embedded in the mounting through hole in the center of the tool holder, and several screws are inserted into the screw holes to fix the tool handle and the tool holder.

[0009] 2. In the above scheme, the number of screw holes is 4.

[0010] 3. In the above scheme, the radius of the arc portion is 0.06mm.

[0011] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0012] 1. The present invention relates to a cutting mechanism for the mid-plate of an ultra-thin smartphone, comprising a first tool group and a second tool group arranged opposite to each other, wherein the workpiece is disposed between the first tool group and the second tool group. The two tool groups are arranged opposite to each other and simultaneously cut the workpiece. By simply setting the stroke difference between the two tool groups, workpieces of various thicknesses can be processed without adjusting the tool stroke when processing workpieces of different thicknesses. This saves a lot of time and manpower, and is a multi-purpose machine that can process workpieces of various thicknesses. It has good versatility, improves production efficiency, and saves manpower.

[0013] 2. This invention relates to a cutting mechanism for ultra-thin smartphone mid-plates. The tool holder is fixed by a tool holder, which has a central mounting through hole and several screw holes on its side surface. The tool holder is inserted into the central mounting through hole, and several screws are inserted into these screw holes to fix the tool holder to the tool holder. The screw holes and screws on the side of the tool holder provide lateral positioning of the tool holder, ensuring stability and preventing tool wobbling due to excessive force during machining. The mechanism also allows for fine-tuning of the tool holder in the X and Y directions, ensuring machining accuracy. Furthermore, it is easy to disassemble and assemble, facilitating tool replacement and saving time.

[0014] 3. The present invention relates to a cutting mechanism for the mid-plate of an ultra-thin smartphone. The upper surface of the blades of the first tool group and the lower surface of the blades of the second tool group are staggered. The edge of the blade of the first tool group is an inwardly inclined slope. The blade of the second tool group is composed of four cutting parts of the same shape spliced ​​together. The cutting part is provided with a cutting edge at the end and has an outwardly protruding arc part at the end of the cutting part, thereby forming a triangular connecting part on the workpiece between the blades of the first tool group and the blades of the second tool group. The arc part of the cutting part of the blade of the second blade group makes the connecting part triangular, that is, the connecting point is a point. It is only necessary to manually break the connecting part. The break point will definitely be the weakest connecting point, so the burrs can be removed. It is simple and easy to operate, and the deburring effect is good. Attached Figure Description

[0021] Example 1: A cutting mechanism for the middle plate of an ultra-thin smartphone includes a first tool group 1 and a second tool group 2 arranged opposite to each other. The workpiece 3 is disposed between the first tool group 1 and the second tool group 2. Both the first tool group 1 and the second tool group 2 include a tool holder 11, a tool neck 12, a blade 13 and a cutting edge 14. The tool neck 12 is fixedly disposed below the tool holder 11. The blade 13 is located on the lower surface of the tool neck 12. The cutting edge 14 is disposed at the outer edge of the blade 13.

[0022] The upper surface of the blade 13 of the first tool group 1 and the lower surface of the blade 13 of the second tool group 2 are staggered. The edge of the blade 13 of the first tool group 1 is an inwardly inclined slope. The blade 13 of the second tool group 2 is composed of four cutting parts 131 of the same shape spliced ​​together. The cutting part 131 is provided with a cutting edge 14 at the end. The cutting part 131 has an outwardly protruding arc part 132 at the end, thereby forming a triangular connecting part on the workpiece 3 between the blade 13 of the first tool group 1 and the blade 13 of the second tool group 2.

[0023] The aforementioned handle 11 is fixed by a tool holder 4. The tool holder 4 has a mounting through hole 5 in the center and several screw holes 6 on its side surface. The handle 11 is embedded in the mounting through hole 5 in the center of the tool holder 4, and several screws 7 are inserted into the screw holes 6 to fix the handle 11 to the tool holder 4.

[0024] Example 2: A cutting mechanism for the mid-plate of an ultra-thin smartphone includes a first tool group 1 and a second tool group 2 arranged opposite to each other. The workpiece 3 is disposed between the first tool group 1 and the second tool group 2. Both the first tool group 1 and the second tool group 2 include a tool holder 11, a tool neck 12, a blade 13 and a cutting edge 14. The tool neck 12 is fixedly disposed below the tool holder 11. The blade 13 is located on the lower surface of the tool neck 12. The cutting edge 14 is disposed at the outer edge of the blade 13.

[0025] The upper surface of the blade 13 of the first tool group 1 and the lower surface of the blade 13 of the second tool group 2 are staggered. The edge of the blade 13 of the first tool group 1 is an inwardly inclined slope. The blade 13 of the second tool group 2 is composed of four cutting parts 131 of the same shape spliced ​​together. The cutting part 131 is provided with a cutting edge 14 at the end. The cutting part 131 has an outwardly protruding arc part 132 at the end, thereby forming a triangular connecting part on the workpiece 3 between the blade 13 of the first tool group 1 and the blade 13 of the second tool group 2.

[0026] The tool holder 4 is connected to the drive mechanism; the number of screw holes 6 is 4; the lower part of the tool holder 11 connected to the tool neck 12 is shaped like an inverted frustum; the radius of the arc portion 132 is 0.06mm; the cutting edge 14 is made of PCD; and the workpiece 3 is fixed by a workpiece holder.

[0027] When using a cutting mechanism for ultra-thin smartphone plates, two tool sets can be positioned opposite each other to cut the workpiece simultaneously. Only the stroke difference between the two tool sets needs to be set to process workpieces of various thicknesses, eliminating the need to adjust the tool stroke for different thicknesses, saving significant time and manpower. This multi-functional machine can process workpieces of various thicknesses, offering excellent versatility, improved production efficiency, and reduced labor costs. Secondly, the screw holes and bolts on the side of the tool holder allow for side positioning of the tool holder, ensuring stability and preventing tool wobbling due to excessive force during processing. It also allows for fine-tuning of the tool holder in the X and Y directions, ensuring machining accuracy. Furthermore, it is easy to disassemble and assemble, facilitating tool replacement and saving time. Thirdly, the arc-shaped cutting section of the second tool set creates a triangular connecting point. This means the connecting point is a single point; simply breaking the connecting point manually removes burrs, making the process simple, easy to operate, and highly effective at deburring.
