Description

Technical Field

[0001] This utility model relates to the technical field of wire cutting, and in particular to a cutting mechanism. Background Technology

[0002] In the field of machining, wire cutting technology is widely used. Its core is to cut long strips of wire into segments using cutting equipment. Existing cutting equipment typically consists of a feeding mechanism, a straightening mechanism, and a cutting mechanism arranged sequentially. The specific workflow is as follows: the wire wound into bundles is first transported intermittently to the corresponding station of the straightening mechanism under the drive of the feeding mechanism. After the straightening mechanism straightens the wire, it is then transported to the cutting mechanism, where it is finally cut into the required segments.

[0003] Traditional cutting mechanisms consist of a die-cutting base, a fixed die core fixed inside the die-cutting base, a sliding block movably mounted on the die-cutting base, a moving die core built into the sliding block, and a hydraulic cylinder for driving the sliding block downwards to complete the cutting action. To ensure the flatness of the wire cut surface, a clamping mechanism is required at the wire feeding end to prevent the wire from shifting during the cutting process. Simultaneously, to avoid wire corner collapse, existing cutting mechanisms often include an auxiliary mechanism at the wire unloading end for support, such as the bar stock disclosed in Chinese Utility Model Patent (Authorization Announcement No.: CN218946092U). The cutting die includes an auxiliary feeding mechanism, which comprises a reset plate, a first reset spring, and a transition plate. The transition plate is connected to the blade plate, and the first reset spring is disposed between the transition plate and the reset plate. The transition plate is also equipped with a push rod for supporting the feeding end of the bar stock (wire). However, the above-mentioned auxiliary feeding mechanism has obvious defects: the push rod will always press against the lower end of the wire under the elastic force of the reset spring, causing the push rod and the wire to be in a state of continuous friction when the wire is fed. As a result, the support surface of the push rod corresponding to the wire is easily worn. Therefore, the operator needs to constantly adjust the height of the push rod to compensate for the wear, which makes the operation very inconvenient.

[0004] To address technical issues such as the easy wear of the wire support surface, the market has been working on improvements and optimizations based on existing technologies. For example, a cutting mechanism disclosed in Chinese Utility Model Patent (Authorization Announcement No.: CN220760870U) includes a fixed mold core and auxiliary components. The fixed mold core has a first channel for the wire to pass through. The auxiliary components consist of a mounting block, a top block, a first elastic element, and a first driving element. The mounting block is located in the accommodating cavity and is fixedly connected to the lower end of the cutting slider. The first driving element is connected to the mounting block, and its output end extends into the slot and is connected to the top block. A second channel for the wire to pass through is formed between the top block and the moving mold core. The top block can switch between supporting and releasing the wire state through the action of the first driving element. The first elastic element acts on the mounting block to provide upward elastic force. Its working process is as follows: In the initial state, the piston rod of the first driving component is in its original position, keeping the top block and the moving mold core at a distance and in an open state, allowing the wire to pass through the first and second channels sequentially for feeding. When the wire feeding length reaches the set value, the first driving component drives the top block to move upward, supporting the wire while simultaneously clamping the unloading end of the wire in cooperation with the moving mold core. Subsequently, the power unit drives the cutting slider to move downward, causing the moving mold core and the top block to move downward synchronously, ultimately completing the cutting action. With the help of auxiliary components, it effectively avoids wear on the supporting surface during wire feeding. Simultaneously, the clamping of the unloading end of the wire by the top block and the moving mold core ensures that the unloading end moves stably downward with the cutting slider, thereby ensuring a flat wire cutting surface and preventing corner collapse.

[0005] However, the cutting mechanism disclosed in the prior art has obvious defects in the cutting process: it first drives the top block to move upward through the first driving component to support the wire and clamp it in cooperation with the moving mold core. Then, the power unit drives the cutting slider to move downward, which drives the moving mold core and the top block to move downward synchronously to complete the cutting action. In this working mode, the driving direction of the first driving component is completely opposite to the driving direction of the power unit. The reverse driving design will greatly increase the time spent on action connection, resulting in a significant reduction in the overall working efficiency of the cutting mechanism. At the same time, the cutting mechanism requires two independent power devices, the first driving component and the power unit. This not only makes the overall structure of the cutting mechanism more complex and increases the difficulty of assembly and maintenance, but also significantly increases the manufacturing cost and operating cost of the equipment.

[0006] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0007] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a cutting mechanism in which the driving force for clamping the workpiece is in the same direction as the driving force for cutting the workpiece, reducing the time spent on connecting the actions, and cutting the workpiece in a smooth manner after clamping it, thereby improving the cutting efficiency of the workpiece, while also simplifying the equipment and facilitating its later maintenance.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A cutting mechanism includes a die-cutting base, a fixed die core fixedly disposed within the die-cutting base, the fixed die core having a first channel for a workpiece to pass through, and a cutting slider cooperating with the fixed die core. The cutting slider includes a first cutting die and a second cutting die adapted to each other, both of which can reciprocate along a first direction of the die-cutting base. A second channel for the workpiece to pass through is provided between the first and second cutting dies, the second channel corresponding to the first channel. An elastic member is abutting between the first and second cutting dies, the elastic member causing the first cutting die to always have a tendency to move away from the second cutting die. The cutting mechanism further includes: a power unit for driving the first cutting die to move in the positive direction of the first direction; when the first cutting die moves to the point where the first and second cutting dies clamp the workpiece, the first cutting die drives the second cutting die to continue moving synchronously in the positive direction of the first direction; and a reset member, which is cooperating with the cutting slider, the reset member being able to drive the second and first cutting dies to move in the negative direction of the first direction. Furthermore, the die-cutting base is provided with a sliding groove, which extends along a first direction of the die-cutting base, and the first cutting die and the second cutting die are respectively slidably disposed in the sliding groove.

[0009] Furthermore, the first cutting die includes a first slider and a first moving die core connected to the first slider, and the second cutting die includes a second slider and a second moving die core connected to the second slider; the first moving die core has a first notch, the second moving die core has a second notch, the first notch and the second notch are disposed opposite to each other, and the second channel is located between the first notch and the second notch.

[0010] Furthermore, the second slider is fixedly connected to a limiting seat, which cooperates with the die-cutting seat to limit the maximum stroke of the second slider in the negative direction of the first direction.

[0011] Furthermore, the first slider has a first mounting groove, and the first moving mold core is at least partially housed within the first mounting groove. The first mounting groove can at least restrict the degree of freedom of the first moving mold core relative to the first slider along a first direction. The second slider has a second mounting groove, and the second moving mold core is at least partially housed within the second mounting groove. The second mounting groove can at least restrict the degree of freedom of the second moving mold core relative to the second slider along a first direction.

[0012] Furthermore, both the first mounting groove and the second mounting groove extend along the second direction. The first slider is connected to a first limiting plate, which at least restricts the degree of freedom of the first moving mold core relative to the first slider along the second direction. The second slider is connected to a second limiting plate, which at least restricts the degree of freedom of the second moving mold core relative to the second slider along the second direction.

[0013] Furthermore, the end of the first channel furthest from the cutting slider is the feeding end, and the feeding end is provided with a guide slope.

[0014] Furthermore, a pair of symmetrically arranged elastic members are provided between the first cutting die and the second cutting die.

[0015] Furthermore, at least one of the first slider and the second slider is provided with a receiving groove, the elastic element is disposed in the receiving groove, one end of the elastic element abuts against the first slider, and the other end of the elastic element abuts against the second slider.

[0016] Furthermore, the reset element is a reset spring, which abuts against the second cutting die; or, the reset element is a gas spring, a gas cylinder, or a hydraulic cylinder, and the output end of the reset element abuts against the second cutting die.

[0017] The beneficial effects of this utility model after adopting the above structure are as follows: The cutting mechanism of this utility model has a power unit that drives the first cutting die to move downwards. When the first cutting die moves to the point where it and the second cutting die clamp the workpiece, the power unit simultaneously drives the first and second cutting dies to move downwards synchronously to cut the workpiece. This ensures that the driving forces for clamping and cutting the workpiece are in the same direction. This innovative mode of co-directional driving completely eliminates the waiting period for action transition in traditional reverse driving. After the action of clamping the workpiece is completed, the cutting process can be started smoothly without additional adjustment of the driving direction, significantly shortening the redundant time of action connection. This not only makes the entire cutting process more coherent and smooth but also more efficient. The total cycle time for a single cut is reduced, significantly improving the overall efficiency of workpiece cutting, which is especially suitable for high-efficiency production capacity requirements in batch workpiece processing scenarios. At the same time, the design of the driving force for clamping and cutting the workpiece in the same direction means that the cutting mechanism does not need to be equipped with two independent power units. Instead, it can realize the two core functions of clamping and cutting the workpiece through a single power unit. This not only greatly simplifies the overall structure of the equipment, reduces the number of parts and assembly nodes, and reduces the complexity and cost of early production and manufacturing, but also makes later equipment maintenance more convenient, further ensuring the stable operation of the production line, while also reducing maintenance costs and manpower input during long-term use.

[0027] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 7 As shown, a cutting mechanism includes a die-cutting base 2, in which a fixed die core 3 is fixedly disposed. The fixed die core 3 has a first channel 31 for the workpiece to pass through. The die-cutting base 2 is also provided with a cutting slider 4 that cooperates with the fixed die core 3. The cutting slider 4 includes a first cutting die 41 and a second cutting die 42 that are adapted to each other. Both the first cutting die 41 and the second cutting die 42 can reciprocate along a first direction of the die-cutting base 2. A second channel 43 for the workpiece to pass through is provided between the first cutting die 41 and the second cutting die 42. The second channel 43 is correspondingly disposed with respect to the first channel 31. The first cutting die 41 and the second cutting die 42 are... An elastic element 5 is provided between the two cutting dies 42, the elastic element 5 causing the first cutting die 41 to always have a tendency to move away from the second cutting die 42; the cutting mechanism also includes: a power unit 6, which is used to drive the first cutting die 41 to move in the positive direction of the first direction, when the first cutting die 41 moves to the point where the first cutting die 41 and the second cutting die 42 clamp the workpiece, the first cutting die 41 drives the second cutting die 42 to continue moving synchronously in the positive direction of the first direction; a reset element 7, which is configured to cooperate with the cutting slider 4, the reset element 7 can drive the second cutting die 42 and the first cutting die 41 to move in the negative direction of the first direction. The reset element 7 is a reset spring, the reset spring abuts against the second cutting die 42; or, the reset element 7 is a gas spring, a cylinder or a hydraulic cylinder, the output end of the reset element 7 abuts against the second cutting die 42. The cutting mechanism also includes: a support base 1, the die-cutting seat 2 is fixedly connected to the support base 1.

[0029] Based on the above embodiments, this utility model provides a cutting mechanism in which the power unit 6 drives the first cutting die 41 to move downward. When the first cutting die 41 and the second cutting die 42 clamp the workpiece, the power unit 6 simultaneously drives the first cutting die 41 and the second cutting die 42 to move downward synchronously to cut the workpiece. This ensures that the driving forces for clamping and cutting the workpiece are in the same direction. This innovative co-directional driving mode completely eliminates the waiting period for action transition in traditional reverse driving. After the action of clamping the workpiece is completed, the cutting process can be started smoothly without additional adjustment of the driving direction, greatly shortening the redundant time of action connection. This not only makes the entire cutting process more coherent and smooth, but also... This significantly reduces the total cycle time of a single cut, greatly improving the overall efficiency of workpiece cutting, and is especially suitable for high-efficiency production capacity requirements in batch workpiece processing scenarios. Simultaneously, the design of the workpiece clamping and cutting driving forces being in the same direction eliminates the need for two separate power units. Instead, a single power unit 6 can achieve both the core functions of clamping and cutting the workpiece. This not only greatly simplifies the overall structure of the equipment, reduces the number of parts and assembly nodes, and lowers the complexity and cost of early-stage manufacturing, but also makes later equipment maintenance more convenient, further ensuring the stable operation of the production line, while also reducing maintenance costs and manpower input during long-term use. Figure 2 As shown, the first direction is the up-down direction of the die-cutting base 2, where the positive direction of the first direction is the vertical downward direction of the die-cutting base 2, and the negative direction of the first direction is the vertical upward direction of the die-cutting base 2; the second direction is the front-back direction of the die-cutting base 2.

[0030] The cutting mechanism operates as follows: Initially, the output of the power unit 6 is in its original position, with a gap between the first slider 411 and the second slider 421, and a gap between the first moving mold core 412 and the second moving mold core 422. At this time, the workpiece can be smoothly fed into the second channel 43. When the workpiece reaches the set length, the power unit 6 drives the first slider 411 to move the first moving mold core 412 downwards until the first moving mold core 412 and the second moving mold core 422 clamp the workpiece. The power unit 6 continues to drive the first slider 411 downwards, and the first moving mold core 412, the workpiece, the second moving mold core 422, and the second slider 421 move downwards synchronously, achieving workpiece cutting. Throughout this process, the driving force of the power unit 6 is always vertically downwards without any noticeable pauses. The clamping and cutting of the workpiece are completed seamlessly, resulting in high cutting efficiency. After cutting is completed, the output end of the power unit 6 resets, and the cutting slider 4 automatically moves upward and resets under the force of the reset member 7. The first slider 411 automatically moves upward and resets under the force of the elastic member 5, so that a preset distance is automatically formed between the first moving mold core 412 and the second moving mold core 422. This ingenious structural design creates a smooth channel for the re-feeding of the workpiece, and the feeding process can be automatically connected without additional adjustment or operation. The entire operation process significantly improves the smoothness and continuity of the cutting cycle, thereby greatly improving the overall cutting efficiency, especially in batch workpiece processing scenarios where its high efficiency advantage is more prominent. In this embodiment, the power unit 6 is a hydraulic cylinder. In this embodiment, the workpiece is wire or bar stock.

[0031] In another preferred embodiment of this utility model, the first cutting mold 41 includes a first slider 411 and a first movable mold core 412 connected to the first slider 411; the second cutting mold 42 includes a second slider 421 and a second movable mold core 422 connected to the second slider 421; the first movable mold core 412 has a first recess 4121, and the second movable mold core 422 has a second recess 4221; the first recess 4121 and the second recess 4221 are disposed opposite to each other, and the second channel 43 is located between the first recess 4121 and the second recess 4221. In this embodiment, as... Figure 6 and Figure 7 As shown, the design of this structure facilitates the replacement of the first moving mold core 412 and the second moving mold core 422 to adapt to the cutting of workpieces with different wire diameters, thereby increasing the versatility of the cutting mechanism.

[0032] As another preferred embodiment of this utility model, the die-cutting base 2 is provided with a sliding groove 21, the sliding groove 21 extending along a first direction of the die-cutting base 2, and the first cutting die 41 and the second cutting die 42 are respectively slidably disposed within the sliding groove 21. In this embodiment, as... Figure 5 and Figure 6As shown, the die-cutting base 2 has a groove 21 with an open top. The cutting slider 4 is movably disposed within the groove 21 along a first direction of the die-cutting base 2. The groove 21 restricts the movement trajectory of the cutting slider 4, causing it to slide along a predetermined path. In a further preferred embodiment, the die-cutting base 2 has a third limiting plate 211, which is fixedly connected to the die-cutting base 2 and restricts the movement of the cutting slider 4 along a second direction. Figure 1 As shown, the third limiting plate 211 is used to restrict the movement of the cutting slider 4 along the second direction, to prevent the cutting slider 4 from coming out of the groove 21, and to improve the reliability of the installation of the cutting slider 4.

[0033] In another preferred embodiment of this utility model, the second slider 421 is fixedly connected to a limiting seat 44, which engages with the die-cutting seat 2 to limit the maximum stroke of the second slider 421 in the negative direction of the first direction. In this embodiment, as... Figure 2 As shown, when the cutting slider 4 moves in the positive direction of the first direction under the force of the power unit 6, the limiting seat 44 moves accordingly. When the cutting slider 4 moves in the negative direction of the first direction under the action of the reset member 7, the limiting seat 44 and the die-cutting seat 2 limit each other to restrict the highest position of the limiting seat 44 and the second slider 421 moving in the negative direction of the first direction. This keeps a gap between the first moving mold core 412 and the second moving mold core 422, and ensures that the second recess 4221 of the second moving mold core 422 is not higher than the height of the lower peripheral wall of the first channel 31, so that the workpiece can enter the second channel 43.

[0034] As another preferred embodiment of this utility model, the first slider 411 has a first mounting groove 4111, and the first moving mold core 412 is at least partially received within the first mounting groove 4111. The first mounting groove 4111 can at least restrict the degree of freedom of the first moving mold core 412 relative to the first slider 411 along a first direction. The second slider 421 has a second mounting groove 4211, and the second moving mold core 422 is at least partially received within the second mounting groove 4211. The second mounting groove 4211 can at least restrict the degree of freedom of the second moving mold core 422 relative to the second slider 421 along a first direction. In this embodiment, as... Figure 5As shown, the first moving mold core 412 is installed through the first mounting groove 4111. Specifically, the first mounting groove 4111 adopts a special structural design that is wider at the top and narrower at the bottom. Utilizing the self-locking characteristics of the wedge-shaped surface, it can provide a stable installation position for the first moving mold core 412 without the need for any fastening connectors such as bolts or clips. After the first moving mold core 412 is embedded in the first mounting groove 4111, the width difference between the top and bottom of the first mounting groove 4111 can form a lateral limit and vertical support for the first moving mold core 412, effectively restricting the sliding of the first moving mold core 412 along the groove in the first direction. This simplifies the assembly process of the first moving mold core 412 and ensures the structural stability after installation, preventing the first moving mold core 412 from shifting due to loose or missing connectors, which would affect the subsequent workpiece processing accuracy. The second mounting groove 4211 adopts a structure design that is wider at the bottom and narrower at the top, which is the opposite of the first mounting groove 4111. When the second moving mold core 422 is embedded in the second mounting groove 4211, it can make full use of the inherent characteristics of the wedge structure to play the same core function as the first mounting groove 4111. That is, it does not need to rely on any fastening connectors such as bolts and pins. The width difference between the top and bottom of the second mounting groove 4211 can form a precise limit and stable support for the second moving mold core 422. This can effectively limit the sliding of the second moving mold core 422 along the groove, ensuring its stable position after installation. It can also save the extra steps of assembling and fastening connectors, simplifying the installation process of the second moving mold core 422. At the same time, it can prevent the second moving mold core 422 from shifting due to loosening or aging of connectors, thereby ensuring the accuracy and stability of subsequent workpiece processing.

[0035] In another preferred embodiment of this utility model, both the first mounting groove 4111 and the second mounting groove 4211 extend along the second direction. The first slider 411 is connected to a first limiting plate 4112, which at least restricts the degree of freedom of the first moving mold core 412 relative to the first slider 411 along the second direction. The second slider 421 is connected to a second limiting plate 4212, which at least restricts the degree of freedom of the second moving mold core 422 relative to the second slider 421 along the second direction. In this embodiment, as... Figure 1As shown, the first limiting plate 4112 is used to restrict the movement of the first moving mold core 412 along the second direction, preventing the first moving mold core 412 from sliding out of the first mounting groove 4111, thus improving the reliability of the installation of the first moving mold core 412. The first limiting plate 4112 is provided with bolts, and the locking force on the first moving mold core 412 is adjusted by the bolts to accommodate first moving mold cores 412 of different thicknesses. The second limiting plate 4212 is used to restrict the movement of the second moving mold core 422 along the second direction, preventing the second moving mold core 422 from sliding out of the second mounting groove 4211, thus improving the reliability of the installation of the second moving mold core 422. The second limiting plate 4212 is provided with bolts, and the locking force on the second moving mold core 422 is adjusted by the bolts to accommodate second moving mold cores 422 of different thicknesses.

[0036] As another preferred embodiment of this utility model, the end of the first channel 31 furthest from the cutting slider 4 is the feeding end, and the feeding end is provided with a guide slope 311. In this embodiment, as... Figure 3 As shown, the guide slope 311 facilitates the entry of the workpiece into the first channel 31 of the fixed mold core 3.

[0037] In another preferred embodiment of this utility model, a pair of symmetrically arranged elastic members 5 are provided between the first cutting die 41 and the second cutting die 42. At least one of the first slider 411 and the second slider 421 is provided with a receiving groove 4213, and the elastic member 5 is disposed within the receiving groove 4213. One end of the elastic member 5 abuts against the first slider 411, and the other end of the elastic member 5 abuts against the second slider 421. At least one of the first slider 411 and the second slider 421 is provided with a guide groove 4113 corresponding to the receiving groove 4213, and the end of the elastic member 5 is received within the guide groove 4113. In this embodiment, as... Figure 5 As shown, the elastic element 5 is a return spring. Two sets of return springs are provided and symmetrically arranged on both sides of the cutting slider 4, making the upward movement and reset of the first slider 411 more stable. The first end of the elastic element 5 is installed through the receiving groove 4213, and the second end of the elastic element 5 is guided through the guide groove 4113 to avoid problems such as displacement or misalignment of the elastic element 5 during compression and restoration.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
