Description

Technical Field

[0001] This application belongs to the field of cutting technology, and in particular relates to a cutting tool. Background Technology

[0002] In industries such as electronics, wind power, photovoltaics, injection molding, and sheet metal processing, process edges are typically reserved during product design to ensure manufacturing precision and ease of subsequent processing. For example, in PCB manufacturing, process edges primarily assist production equipment operation, including clamping, conveying, soldering, and inspection. In sheet metal processing, process edges are used for positioning and assisting in processes such as cutting and bending. These process edges need to be removed after product processing to meet the final dimensional and appearance requirements.

[0003] However, existing methods for removing process edges have many problems. Manual trimming results in poor consistency and low efficiency, making it difficult to meet increasingly stringent product quality requirements. Using trimming equipment increases product turnaround time and equipment investment costs. Therefore, existing methods for removing process edges can no longer meet the industry's demands for high precision, high efficiency, and low cost. Utility Model Content

[0004] This application provides a cutting tool to solve the technical problems of low accuracy and efficiency and high cost in removing process edges in the prior art.

[0005] In a first aspect, embodiments of this application provide a cutting tool, the cutting tool comprising:

[0006] A cutting body, the cutting body including a pressing member and a cutting member, the pressing member being drivenly connected to the cutting member, the cutting member including two spaced-apart cutting blocks, the pressing member driving the two cutting blocks to approach each other and at least partially abut against each other to cut the product;

[0007] A positioning element is disposed on the periphery of the two cut blocks and is used to limit the cutting length of the product.

[0008] Optionally, each of the cut blocks has a cutting tooth at the end away from the pressing member. One end of the cutting tooth extends out of the outside of the cut block and forms a blade. The pressing member drives the two cut blocks to bring the blades of the two cutting teeth into contact to cut the product.

[0009] Optionally, the cutting teeth, at least the cutting edge, are arc-shaped.

[0010] Optionally, the cutting teeth, at least the cutting edge, are straight in shape.

[0011] Optionally, the positioning element includes two positioning posts, which are respectively disposed on both sides of the cutting block, and the two positioning posts are used to abut against the product when cutting the product.

[0012] Optionally, both positioning posts are flush with the end face of the cutting block that is away from the pressing member.

[0013] Optionally, the two positioning posts and the cutting block are integrally formed.

[0014] Optionally, the two positioning posts are detachably threaded to the cutting block.

[0015] Optionally, the pressing element includes two handles, and the cutting body also includes a rotating shaft and a rotating ring. The rotating shaft is rotatably disposed within the rotating ring. One of the handles and one of the cutting blocks are connected to the rotating shaft, and the other handle and another cutting block are connected to the rotating ring.

[0016] Optionally, the cutting body further includes a spring, the two ends of which are respectively connected to the two handles and located at the end of the handles near the pivot. The spring provides a restoring force after the two handles are pressed.

[0017] The cutting tool provided in this application includes a cutting body and a positioning member. The cutting body includes a pressing member and a cutting member, which are drivenly connected. The cutting member includes two spaced-apart cutting blocks, and the positioning member is disposed on the periphery of the two cutting blocks. When cutting the process edge of a product, the product is inserted into the gap between the two cutting blocks. At this time, the positioning member limits the depth of the product inserted into the gap. Pressing the pressing member drives the two cutting blocks to approach each other and at least partially abut. At this time, the abutting part of the two cutting blocks cuts off the process edge of the product. Therefore, through the above structural design, this application can accurately remove the process edge of the product, improve the efficiency of process edge cutting, eliminate the need for cutting equipment, and reduce production costs.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] In manufacturing sectors such as electronics, wind power, photovoltaics, injection molding, and sheet metal processing, certain process edges are typically reserved during the product design phase to ensure product precision during manufacturing and smooth subsequent processing. For example, in PCB manufacturing, these process edges primarily assist production equipment in operations such as clamping, conveying, soldering, and inspection; while in sheet metal processing, process edges are mainly used for positioning and auxiliary operations in processes such as cutting and bending. However, these process edges usually need to be removed after product processing to ensure that the product meets the final dimensional and appearance requirements.

[0027] However, current methods for removing these process edges have many shortcomings. Manual removal is not only inefficient but also difficult to guarantee consistency, failing to meet increasingly stringent product quality standards. While using specialized cutting equipment can improve efficiency, it increases product turnaround time and equipment investment costs. Therefore, existing methods for removing process edges are no longer adequate to meet the industry's comprehensive demands for high precision, high efficiency, and low cost.

[0028] To address the technical problems of low accuracy and efficiency, and high cost in edge removal in existing technologies, this application provides a cutting tool to solve the problems of low cutting accuracy and efficiency, and high structural cost of existing cutting tools. The following description is in conjunction with the accompanying drawings.

[0029] Combination Figures 1 to 3As shown, the cutting tool includes a cutting body 10 and a positioning member 20; the cutting body 10 includes a pressing member 11 and a cutting member 12, the pressing member 11 and the cutting member 12 are drivenly connected, the cutting member 12 includes two spaced cutting blocks 121, the pressing member 11 drives the two cutting blocks 121 to approach each other and at least partially abut each other to cut the product; the positioning member 20 is disposed on the periphery of the two cutting blocks 121 and is used to limit the cutting length of the product.

[0030] In this embodiment, the pressing element 11 is made of a high-strength, lightweight alloy material, possessing excellent wear resistance and toughness. The surface of the pressing element 11 is covered with an anti-slip material to increase friction and prevent hand slippage during operation. The drive connection between the pressing element 11 and the cutting element 12 employs a lever principle, connecting the two via a rotating shaft 14. When the user presses the pressing element 11, the lever system transmits force to the cutting element 12, causing the two cutting blocks 121 to move towards each other. The rotating shaft 14 uses a low-friction bearing design to reduce movement resistance and make operation smoother. Alternatively, the driving force of the pressing element 11 can also be transmitted to the cutting element 12 via a drive structure such as gears or linkages.

[0031] The cutting block 121 is made of carbon steel and heat-treated. The part that abuts when two cutting blocks 121 are close together is ground to ensure a sharp and durable cutting edge. The cutting block 121 can be rectangular, arc-shaped, wavy, or serrated, etc. Users can choose different shapes of cutting blocks 121 according to the actual needs of the product cutting process edge shape.

[0032] Positioning elements 20 are located on the periphery of the two cutting blocks 121 to limit the cutting length of the product. The positioning elements 20 are made of corrosion-resistant metal and are fixed to the cutting blocks 12 by threaded connection or are integrally formed with the cutting blocks 12.

[0033] When trimming the process edges of a product, the process edges are inserted into the gap between two cutting blocks 121, while the product abuts against the positioning member 20. At this time, the positioning member 20 limits the insertion depth of the process edges, ensuring that the trimming length is consistent each time. The user only needs to push the product in until it abuts against the positioning member 20, and then press the pressing member 11 to drive the two cutting blocks 121 closer together and partially abut, thereby trimming the process edges of the product and ensuring that the trimming length of the process edges of each product remains consistent. Therefore, through the above structural design, this application can accurately remove the process edges of the product, while improving the efficiency of process edge trimming, eliminating the need for cutting equipment, and reducing production costs.

[0034] Optional, such as Figures 1 to 3As shown, each cutting block 121 has a cutting tooth 122 at the end away from the pressing member 11. One end of the cutting tooth 122 extends out of the outside of the cutting block 121 and forms a blade. The pressing member 11 drives the two cutting blocks 121 to bring the blades of the two cutting teeth 122 into contact to cut the product.

[0035] In this embodiment, the cutting teeth 122 are designed to improve the cutting effect and ensure a smoother and neater cut surface. One end of the cutting teeth 122 extends outward from the outer side of the cutting block 121 and forms a blade. The pressing member 11 drives the two cutting blocks 121 to bring the blades of the two cutting teeth 122 into contact to complete the cutting operation. The blades are chamfered so that the cross-sectional size of the blades gradually decreases in the direction away from the cutting block 121, thereby improving cutting efficiency and cutting accuracy.

[0036] In addition, blades of different shapes can be used for cutting the edges of products of different shapes.

[0037] Optional, such as Figure 3 As shown, at least the cutting edge of the cutting tooth 122 is arc-shaped. The cutting edge can be designed to be arc-shaped, or the overall shape of the cutting tooth 122 can be arc-shaped. When the pressing member 11 drives the two cutting edges to approach and abut, the arc-shaped cutting edge can cut an arc-shaped process edge. Therefore, it can be applied to the cutting of process edges with rounded chamfers, thus completing the cutting of the process edge and edge chamfering simultaneously in one cut, improving overall processing efficiency.

[0038] Optional, such as Figure 1 and Figure 2 As shown, at least the cutting edge of the cutting tooth 122 is straight. The cutting edge can be designed to be straight, or the overall shape of the cutting tooth 122 can be designed to be straight. Therefore, when the pressing member 11 drives the two cutting edges to approach and abut, the straight-shaped cutting edge can cut the protruding process edge on the straight side of the product, thus ensuring that the side of the cut product is relatively smooth.

[0039] In other embodiments, the cutting edge may also be designed as a serrated shape, for example, the cutting edge includes multiple small triangular protrusions arranged alternately; or it may be designed as a wave shape so that the cutting teeth 122 can better adapt to cutting process edges of different shapes.

[0040] The cutting teeth 122 can be manufactured integrally with the cutting block 121. This method results in high strength and integrity of the cutting part 12, making it suitable for long-term use. The integral structure can be achieved through precision casting or forging processes, ensuring a seamless connection between the cutting teeth 122 and the cutting block 121.

[0041] The cutting teeth 122 and the cutting block 121 can also adopt a detachable modular design, allowing users to replace different types of cutting teeth 122 according to different cutting needs. The modular design not only improves the applicability of the equipment but also reduces maintenance costs. Each modular cutting tooth 122 can be fixed to the cutting block 121 by a pin or quick-connect device, making it convenient and quick to replace and adjust.

[0042] Optional, such as Figures 1 to 3 As shown, the positioning component 20 includes two positioning posts 21, which are respectively located on both sides of the cutting block 121. The two positioning posts 21 are used to abut against the product when cutting the product.

[0043] The positioning post 21 can be cylindrical, square, or other polygonal in shape, specifically designed according to the shape of the contact surface between the positioning post 21 and the product, to ensure a large contact area between the positioning post 21 and the product. Two positioning posts 21 are respectively positioned on both sides of the cutting block 121 to ensure more uniform contact force on both sides of the product at the process edge, thereby improving cutting accuracy. The positioning post 21 limits the insertion depth of the product, ensuring consistent cutting length each time. The user simply pushes the product into the position set by the positioning post 21, then presses the pressing member 11, driving the two cutting blocks 121 to bring the blades of the two cutting teeth 122 into contact, thus cutting off the process edge of the product.

[0044] The design of the positioning post 21 not only limits the cutting length of the product, but also serves as a guide, ensuring the product remains stable during the cutting process. Especially when cutting thinner or softer products, the positioning post 21 can effectively prevent the product from shifting or deforming, improving the accuracy and consistency of the cutting.

[0045] Optional, such as Figure 1 and Figure 2 As shown, both positioning posts 21 are flush with the end face of the cutting block 121 away from the pressing member 11. When the cutting block 121 is provided with a cutting tooth 122 at one end away from the pressing member 11, the two positioning posts 21 are flush with the end face of the cutting tooth 122. Therefore, when cutting the process edge of the product, after the side edge of the product abuts against the positioning post 21, the process edge of the product extends between the two cutting blocks 121. At this time, the cutting position of the two cutting teeth 122 is just flush with the side edge of the product. In other words, setting the two positioning posts 21 flush with the end face of the cutting block 121 away from the pressing member 11 can improve the smoothness of the side edge of the product after the process edge is cut.

[0046] The two positioning posts 21 and the cutting block 121 are integrally formed, so there is no need to assemble the positioning posts 21 and the cutting block 121, thereby improving the efficiency of the cutting tool assembly. At the same time, it reduces the error during the assembly of the positioning posts 21 and the cutting block 121, thereby improving the cutting accuracy of the product's process edges.

[0047] In another embodiment, the two positioning posts 21 are detachably threadedly connected to the cutting block 121. The positioning posts 21 are fixed to the cutting body 10 by threaded connection. The user can rotate the positioning posts 21 to assemble and disassemble the cutting block 121, which is a design that facilitates the installation, disassembly, and replacement of the positioning posts 21 and provides high flexibility. Furthermore, multiple threaded connection holes can be provided on the two cutting blocks 121, and the position of the positioning posts 21 can be changed by changing the connection of the positioning posts 21 to different threaded connection holes, thereby adjusting the cutting width of the process edge. Of course, the positioning posts 21 can also be fixed to the cutting body 10 by snap-fit ​​connection. The user only needs to insert the positioning posts 21 into the corresponding slots to complete the fixation.

[0048] Optional, such as Figures 1 to 3 As shown, the pressing component 11 includes two handles 111, and the cutting body 10 also includes a rotating shaft 14 and a rotating ring 13. The rotating shaft 14 is rotatably disposed in the rotating ring 13. One handle 111 and a cutting block 121 are connected to the rotating shaft 14, and the other handle 111 and another cutting block 121 are connected to the rotating ring 13.

[0049] In this embodiment, the pressing member 11 consists of two handles 111, each ergonomically designed and covered with a non-slip material (such as rubber or silicone) to increase friction and prevent hand slippage during operation. The rotating shaft 14 is rotatably mounted within the rotating ring 13, forming a flexible rotating joint. Both the rotating shaft 14 and the rotating ring 13 are made of high-strength stainless steel and integrate a low-friction bearing design to reduce movement resistance and make operation smoother.

[0050] One handle 111 is directly and fixedly connected to the rotating shaft 14. When the user presses the handle 111, the rotating shaft 14 rotates, causing the connected cutting block 121 to move. The other handle 111 is fixedly connected to the rotating ring 13. When the user presses the handle 111, the rotating ring 13 remains stationary, while the connected cutting block 121 moves relative to it. This design forms a lever system, achieving the opposite movement of the two cutting blocks 121 through the coordinated action of the rotating shaft 14 and the rotating ring 13.

[0051] In actual operation, the user holds both handles 111 and inserts the product into the gap between the two cutting blocks 121. The product is pushed into the position set by the positioning post 21 to ensure consistent cutting length. Simultaneously pressing both handles 111 causes relative rotation between the rotating shaft 14 and the rotating ring 13, moving the two cutting blocks 121 towards each other. When the two cutting blocks 121 abut against each other, the cutting edge of the cutting teeth 122 contacts and cuts off the product's edge.

[0052] Optional, such as Figures 1 to 3As shown, the cutting body 10 also includes a spring 15, the two ends of which are connected to two handles 111 respectively, and are located at the end of the handles 111 near the pivot 14. The spring 15 provides the restoring force after the two handles 111 are pressed.

[0053] In this embodiment, the spring 15 is made of high-quality carbon spring steel, possessing excellent elasticity and fatigue resistance. Both ends of the spring 15 are connected to the two handles 111 via threaded connections or other mechanical fixing methods. To ensure a secure connection, lock nuts or other fixing devices can be used at the connection points. When the user presses down on the two handles 111, the spring 15 is compressed and stores energy. After releasing the pressing force, the spring 15 returns to its original shape, pushing the two handles 111 back to their initial position, thus achieving an automatic reset function. This design not only improves operational efficiency but also reduces the user's workload, making it particularly suitable for scenarios requiring frequent operation.
