Description

Technical Field

[0001] This utility model relates to the field of wire cutting, and in particular to a circular wire cutting machine for cutting large-sized irregularly shaped workpieces. Background Technology

[0002] In new energy photovoltaic and energy storage equipment, the use of large-size graphite electrodes and silicon carbide substrates has surged. These materials need to be cut into irregular grooves, stepped surfaces, and other structures to adapt to equipment assembly, and the kerf width must be ≤0.3mm to reduce material loss and ensure a smooth cut surface. Due to the brittleness of graphite and the high hardness of silicon carbide, stable fixation is required during cutting to prevent edge chipping caused by vibration. At the same time, the cutting mechanism needs to be able to penetrate deep into the workpiece to complete complex trajectory processing. Existing equipment tooling fixtures often cannot meet the requirements due to "insufficient load-bearing area" or "cutting space obstruction". In the current technology, if the load-bearing area of ​​the worktable is increased to improve stability, it will obstruct the movement path of the cutting mechanism; if the size of the worktable is reduced to reserve cutting space, it cannot stably support heavy workpieces. This contradiction between "load-bearing" and "cutting" has become the core pain point restricting the development of the industry.

[0003] The prior art (CN 212554482 U) provides a vertical open-loop reciprocating diamond wire profile cutting machine, including a worktable for placing the workpiece and a cutting mechanism for cutting the workpiece. The cutting mechanism includes a frame, a mounting frame, a saw wire, multiple wire rollers, a first take-up and unload device, and a second take-up and unload device. The mounting frame is movably mounted on the frame and can drive the sawing part to form a curved cutting trajectory. Although the second support platform for placing the stone in this invention can be raised, lowered, rotated, and translated in one dimension, the second support platform can only provide a bearing surface for the center of the stone, and there is no fixing device for the stone on the second support platform. During the cutting process, the stone displacement and vibration cause chipping, affecting the cutting effect. If the second support platform is large enough, its shape will limit the range of motion of the cutting mechanism, making it difficult to achieve complex curved surfaces or large-span cutting paths. That is, this device faces a contradiction between sufficient bearing area and sufficient cutting space when bearing large-sized and heavy materials.

[0004] The prior art (CN 214644915 U) provides a diamond wire cutting device, including a frame, a movable working chassis, a rotary table, a special tooling frame, a diamond wire cutting mechanism, a ventilation and chip removal mechanism, and a control system. The movable working chassis includes an X-axis moving frame and a Y-axis moving frame. The X-axis moving frame is fixed on the frame, and the Y-axis moving frame is fixed on the X-axis moving frame. A rotary table is installed on the Y-axis moving frame. The rotary table can rotate within a 360-degree range. A tooling frame is installed on the rotary table to fix the workpiece. However, the tooling frame of this invention uses a central column to fix the material to be cut on the tooling frame, which damages the structural integrity of the material to be cut. Moreover, the vibration generated during cutting causes the material to chip at the edges, affecting the cutting effect. When cutting large-sized and heavy materials, the two-dimensional motion support structure of this invention is complex and easily damaged. Furthermore, the tooling frame for fixing the workpiece cannot simultaneously provide sufficient cutting space and sufficient load-bearing area. Utility Model Content

[0005] The technical problem solved by this utility model is that, for large-sized materials to be cut, the worktable in existing diamond wire cutting equipment cannot simultaneously provide sufficient cutting space and sufficient bearing area. To solve the above problem, a circular wire cutting machine for cutting large-sized irregular workpieces is provided.

[0006] This utility model is achieved in the following manner: A circular cutting machine for cutting large-sized irregularly shaped workpieces includes a frame with a first translation mechanism and a second translation mechanism. The first translation mechanism is fixed with a circular cutting mechanism for cutting materials, and the circular cutting mechanism has a cutting groove. The second translation mechanism is fixed with a rotating mechanism, and the rotating mechanism has a worktable that can rotate within a 360-degree range. The worktable is cross-shaped, and its top surface is higher than the bottom edge of the cutting groove but lower than the top edge of the cutting groove. The first and second translation mechanisms form an angle, allowing a portion of the material to be cut on the worktable to extend into the cutting groove for cutting.

[0007] Preferably, a clamping mechanism is provided above the worktable.

[0008] Preferably, the angle between the first translation mechanism and the second translation mechanism is 60 degrees, 90 degrees, or 120 degrees.

[0009] Preferably, the worktable is provided with an insertion hole, and the clamping mechanism is provided with an insertion post. The clamping mechanism is installed on the worktable by the insertion post cooperating with the insertion hole.

[0010] Preferably, the system further includes a control system, which includes a controller. The driving mechanism of the first translation mechanism is a first lead screw motor, the driving mechanism of the second translation mechanism is a second lead screw motor, the driving mechanism of the rotation mechanism is a motor, and the first driving mechanism driving the drive wheel, the second driving mechanism driving the tension wheel, the first lead screw motor, the second lead screw motor, and the motor on the cutting mechanism are all electrically connected to the controller.

[0011] Compared to existing technologies, the workbench for placing materials to be cut in this invention is designed with a cross-shaped structure, supporting the horizontal and vertical axes of the materials to be cut. This not only allows for the support of large-sized materials, providing sufficient bearing area and stable bearing performance, but also provides ample cutting space, creating a construction location for complex cutting paths, thus satisfying both the requirements for "bearing area" and "cutting space".

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer with the description. However, unless otherwise specified, the specific experimental methods involved in the following embodiments are conventional methods or implemented according to the conditions recommended in the manufacturer's instructions.

[0020] Reference Figures 1-6 A circular cutting machine for cutting large-sized irregularly shaped workpieces includes a frame 1. The frame 1 is provided with a first translation mechanism 4 and a second translation mechanism 5. The first translation mechanism 4 is fixedly provided with a circular cutting mechanism 2 for cutting materials. The second translation mechanism 5 is fixedly provided with a rotating mechanism 3. The rotating mechanism 3 is fixedly provided with a worktable 6, which can rotate within a 360-degree range. The worktable (6) is cross-shaped, which can not only carry large-sized materials to be cut, but also provide more clearance space, and will not obstruct the circular cutting mechanism 2 from cutting the materials to be cut. It can avoid more complex cutting paths and simultaneously meet the requirements of "carrying area" and "cutting space". In addition, the worktable is cross-shaped with a large clearance space. When cutting the four corners of the material, there is no obstruction under the worktable, and the chips fall directly down, which facilitates the discharge of cutting chips and coolant and reduces the impact on cutting. The top surface of the worktable is higher than the bottom edge of the cutting groove 22 but lower than the top edge of the cutting groove 22, allowing the worktable and the material 8 to be cut placed on it to enter the cutting groove. The first translation mechanism 4 and the second translation mechanism 5 form an angle, allowing a portion of the material to be cut on the worktable 6 to extend into the cutting groove 22 for cutting. In this embodiment, existing magnetic suction, vacuum adsorption, and edge limiting blocks are used to fix large-sized materials 8 onto the cross-shaped worktable, while small-sized materials 8 can be fixed onto the cross-shaped worktable by adhesive.

[0021] In another embodiment, a clamping mechanism 7 is provided above the worktable 6. The clamping mechanism fixes the material to be cut on the worktable to prevent the material from moving and to avoid the vibration generated during cutting causing the material to chip and affect the cutting effect.

[0022] By adjusting the relative position between the ring cutting mechanism 2 and the rotating mechanism 3 through the first translation mechanism 4 and the second translation mechanism 5, that is, by adjusting the relative position between the ring cutting mechanism 2 and the material to be cut, the cutting trajectory is changed, and the irregular cutting of the material to be cut is realized. When the worktable on the ring cutting mechanism 2 and the rotating mechanism 3 moves in coordination and actively with the three driving mechanisms of the first translation mechanism 4, the second translation mechanism 5 and the rotating mechanism 3, more complex irregular contours are cut out.

[0023] The included angle between the first translation mechanism 4 and the second translation mechanism 5 is 60 degrees, 90 degrees, or 120 degrees. Preferably, the included angle is 90 degrees, that is, the first translation mechanism 4 and the second translation mechanism 5 are perpendicular to each other. Specifically, the first translation mechanism 4 is arranged along the length direction of the frame 1, and the second translation mechanism 5 is arranged along the width direction of the frame 1. The first translation mechanism 4 drives the circular wire cutting mechanism 2 to move along the length direction of the frame 1, and the second translation mechanism 5 drives the rotating mechanism 3 and the worktable 6 to move along the width direction of the frame 1.

[0024] Furthermore, such as Figure 1 As shown, the workbench 6 is provided with an insertion hole 61, and the clamping mechanism 7 is provided with an insertion post 71. The clamping mechanism is installed on the workbench by the insertion post 71 cooperating with the insertion hole 61. The position of the clamping mechanism 7 can be moved according to the size of the material to be cut, so that the material to be cut is fixed on the workbench 6 and the area to be cut of the material to be cut is placed outside the boundary of the workbench, so as to achieve cutting of complex trajectories.

[0025] Furthermore, such as Figure 6 As shown, the clamping mechanism 7 includes a positioning plate 72 and a clamping plate 73. The clamping plate 73 is arranged parallel to the positioning plate 72. A connecting rod 74 is provided between the clamping plate 73 and the positioning plate 72. One end of the connecting rod 74 is fixedly connected to the clamping plate 73, and the other end is slidably connected to the positioning plate 72. A positioning screw 75 is threaded to the side of the positioning plate 72. The positioning screw 75 is arranged parallel to the connecting rod, and one end of the positioning screw 75 is fixedly connected to the clamping plate 73. The distance between the clamping plate 73 and the positioning plate 72 is adjusted by the positioning screw 75. Through the cooperation of the clamping mechanism, the material to be cut is fixed on the worktable. A pin 71 is provided below the positioning plate 72. The pin 71 is perpendicular to the connecting rod 74 and the positioning plate 72. The clamping mechanism is installed on the worktable by the pin 71 cooperating with the insertion hole 61.

[0026] Furthermore, such as Figure 4 , 5 As shown, the rotating mechanism 3 also includes a base 31, with a fixed platform 32 fixed above the base 31. A fixed shaft 33 is located at the center of the fixed platform 32, and an external gear 34 is sleeved on the fixed shaft 33. The fixed shaft 33 and the external gear 34 are rotatably connected. The external gear 34 is fixedly connected to the worktable 6, and the external gear drives the worktable 6 to rotate. The external gear 34 meshes with a drive wheel 35. A motor 36 is located below the fixed platform 32, and the output shaft of the motor 36 is connected to the drive wheel 35. When the motor 36 is started, the drive wheel 35 is driven to rotate, which in turn drives the external gear to rotate, so that the worktable 6 rotates within a 360-degree range. The first translation mechanism and the second translation mechanism realize the irregular cutting of the material to be cut.

[0027] The outer shell 37 is provided between the fixed platform and the base to prevent the cutting debris from entering the rotating mechanism and affecting its operation.

[0028] Furthermore, such as Figures 1-3As shown, the circular cutting mechanism 2 includes a cutting frame 21. A cutting groove 22 is provided on the side of the cutting frame 21 near the rotating mechanism 3. The bottom edge of the cutting groove is lower than the worktable, and the cutting groove can accommodate the material to be cut. A wire wheel structure 23 is rotatably provided on the cutting frame on the upper and lower sides of the cutting groove 22, and a cutting wire 24 is sleeved along the wire wheel structure 23. The cutting wire 24 forms a cutting area 25 at the cutting groove 22, which can accurately cut the material placed on the worktable.

[0029] Specifically, the wire reel structure 23 includes a driving wheel 231, two driven wheels 232, and a tensioning wheel 233. A cutting wire 22 is arranged in a guide groove on the outer periphery of the driving wheel 231, driven wheels 232, and tensioning wheel 233. The rotation of the driving wheel 231 drives the cutting wire 22 to move between the driving wheel 231, driven wheels 232, and tensioning wheel 233, forming a ring-shaped cutting wire. This ring-shaped cutting wire forms a cutting zone at the cutting groove for cutting materials. The cutting wire is diamond wire, which has extremely high cutting precision, good surface finish, low material loss, and high processing efficiency. It also features a small kerf, less contamination, and material savings.

[0030] The driving wheel 231, the two driven wheels 232, the tension wheel 233 and the tension wheel 233 are all existing technologies. The side of the cutting frame away from the thread wheel structure is provided with a tension wheel assembly corresponding to the tension wheel 233. The tension wheel assembly can be the tension wheel group in Chinese invention patent CN 113894949 A, in which the tension wheel is the tension wheel 233.

[0031] The thread wheel structure 23 is arranged in a rectangular shape, which can cut out flat curved surfaces. The thread wheel structure 23 is arranged in a parallelogram shape, which can cut out conical curved surfaces.

[0032] Furthermore, such as Figures 1-2 As shown, the first translation mechanism 4 includes two parallel horizontal guide rails 41, on which a movable seat 42 is mounted. The first translation mechanism 4 also includes a drive mechanism 43 for driving the movable seat 42 to slide. The drive mechanism can be a hydraulic cylinder, or a lead screw motor and a lead screw. In this embodiment, a first lead screw motor 431 and a lead screw 432 are used. A lead screw nut is mounted on the lead screw, and the movable seat 42 is mounted on the lead screw nut and moves back and forth with the lead screw nut. The cutting frame of the loop cutting mechanism 2 is fixed on the movable seat 42, and the cutting frame is vertically mounted on the movable seat. The second translation mechanism 5 has the same structure as the first translation mechanism 4. The drive mechanism of the second translation mechanism 5 uses a second lead screw motor 531 and a lead screw 532. A base 31 is fixed on the movable seat of the second translation mechanism 5. Furthermore, the circular cutting machine for cutting large-sized irregularly shaped workpieces also includes a control system. This control system sets the cutting path according to the workpiece's processing requirements. The control system includes a controller. The driving mechanism for the first translation mechanism 4 is a first lead screw motor 431, the driving mechanism for the second translation mechanism 5 is a second lead screw motor 531, and the driving mechanism for the rotation mechanism 3 is a motor 36. The first driving mechanism driving the drive wheel, the second driving mechanism driving the tension wheel, the first lead screw motor 431, the second lead screw motor 531, and the motor 36 on the cutting mechanism are all electrically connected to the controller. The controller controls the operation of the first translation mechanism 4, the second translation mechanism 5, and the rotation mechanism 3, cutting the material to be cut according to the set cutting path to meet processing requirements.

[0033] The working process of this utility model is as follows: A large piece of material to be cut is placed on the cross-shaped worktable 6, with the area to be cut positioned outside the worktable's boundary. This design provides stable support for the large material while allowing ample cutting space for complex cutting paths. The clamping mechanism is fixed near the material, and the positioning bolts are adjusted so that the clamping plate 73 abuts against the edge of the material. The material is then secured to the worktable 6 through the cooperation of the clamping mechanisms. A cutting path is set according to the processing requirements, and the control system controls the operation of the first translation mechanism 4, the second translation mechanism 5, and the rotation mechanism 3 to cut the material according to the set path, meeting the processing needs. During cutting, there are no obstructions below the worktable, allowing debris to fall directly down, facilitating the discharge of cutting debris and coolant and minimizing the impact on the cutting process.

[0034] In this invention, the workbench for placing the material to be cut is designed with a cross-shaped structure, supporting the horizontal and vertical axes of the material to be cut. It can not only bear large-sized materials and provide stable load-bearing performance, but also provide sufficient cutting space and construction position for complex cutting paths. At least two clamping mechanisms are set on the workbench to fix the material to be cut on the workbench and prevent the material from moving and affecting the cutting effect.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
