Description

Technical Field

[0001] This utility model belongs to the field of insulation board processing technology, and specifically relates to an insulation board wire cutting device. Background Technology

[0002] Currently, insulating boards are widely used in electrical equipment, electronic products, and construction. The precision and stability of their cutting directly affect the subsequent assembly effect and performance. Traditional insulating board cutting relies mostly on manual operation or conventional cutting machines, typically using the high-speed movement of a metal wire to cut the board. However, due to the brittle nature and limited overall strength of the insulating board, the cutting process often results in the front end of the board being suspended in the air or uneven stress, easily leading to deformation or bending of the board, thus affecting the cutting precision and the smoothness of the cut.

[0003] Meanwhile, while existing wire EDM equipment can achieve longitudinal and transverse movement and cutting, the sheet metal lacks effective limiting and support mechanisms during the cutting process. This is especially true in the wire cutting area, where the stressed parts cannot be stably constrained, easily leading to cutting deviation or a decline in surface quality. Furthermore, to ensure the stability of the processing, operators often need to manually support the sheet metal, which not only increases labor intensity but also poses certain safety hazards. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide an improved wire cutting device for insulating boards, which can effectively fix and support the insulating boards during the cutting process, thereby improving cutting stability and processing quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An insulating board wire cutting device includes a machine body, the main body of which has a forward-opening U-shaped structure, and longitudinal lead screws are installed on both sides of the worktable surface of the machine body, both of which are controlled by a motor.

[0007] A movable frame is slidably mounted on the surfaces of the two longitudinal lead screws, and a transverse sliding plate is slidably mounted on the rear side above the movable frame. The transverse sliding plate is used to clamp and fix the rear side of the insulating board.

[0008] Both sides of the machine body are provided with protrusions, and the top of the protrusions is vertically fixed with a fixing rod. The two fixing rods are respectively placed on the outside of the movable frame.

[0009] A lower limit beam is fixedly installed between the two fixed rods, and an upper limit beam is slidably installed between the two fixed rods.

[0010] Furthermore, the movable frame has a U-shaped structure with an open front end, and both ends of the rear side of the upper surface of the movable frame are provided with protruding plates, and a transverse lead screw is horizontally rotatably installed between the two protruding plates.

[0011] One of the convex plates has a motor fixed to its outer side, and one end of the transverse lead screw is mounted on the motor output end.

[0012] Furthermore, the transverse sliding plate is screwed onto the surface of the transverse lead screw. The transverse sliding plate is stepped, and a mounting platform is recessed downward on the front side of the upper surface of the transverse sliding plate. The rear side of the insulation board to be cut is mounted on the surface of the transverse sliding plate.

[0013] Furthermore, rotating bolts are vertically and rotatably installed on both sides of the upper surface of the transverse sliding plate. A pressure plate is screwed through the surface of the rotating bolt. The pressure plate extends forward, and a pressure head is provided at the front end of the pressure plate. The two pressure heads press and fix the insulating plate below.

[0014] Furthermore, the upper limit beam and the lower limit beam are respectively placed above and below the insulating board to be cut, and a metal wire is vertically arranged inside the machine body, with the upper limit beam placed behind the metal wire.

[0015] Furthermore, a triangular extension frame is provided at the center of the front side of the lower limit beam, the metal wire passes through the center of the triangular extension frame, and ball bearings are evenly installed on the lower surface of the upper limit beam.

[0016] Ball bearings are installed at the three corners of the upper surface of the triangular extension frame, and the upper and lower ball bearings respectively contact the upper and lower surfaces of the insulating board to be cut.

[0017] Furthermore, a limiting nut is screwed onto the top of the fixing rod, a spring is sleeved on the surface of the fixing rod, the upper limit beam is placed between the limiting nut and the upper limit beam, and the spring applies a downward thrust to the upper limit beam.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] During the cutting of insulating boards, warping and deformation easily occur due to the limited strength of the board and its suspended front end, leading to a decrease in cutting accuracy. This device is equipped with an upper limit beam and a lower limit beam in the wire cutting area. The upper limit beam applies downward pressure to the insulating board under the action of a spring, while the lower limit beam is supported from below by a fixing rod. The clamping structure between the upper and lower parts ensures that the insulating board remains stable during the cutting process, effectively avoiding warping and bending caused by uneven force, and improving the flatness and accuracy of the cut.

[0020] Existing devices lack auxiliary guiding structures during cutting, causing the sheet material to easily vibrate or deviate from the wire during movement, affecting the cutting effect. This solution incorporates ball bearings on the contact surfaces of the upper limit beam and the triangular extension frame. These ball bearings provide stable support when in contact with the insulating sheet, reducing friction and allowing the insulating sheet to move smoothly under the drive of the longitudinal and transverse lead screws. This ensures the stability of the cutting trajectory, thereby achieving high-precision cutting of the insulating sheet into any shape.

[0021] In traditional processing, operators often need to manually support the insulating board, increasing labor intensity and posing safety hazards. This device, through a combination of limit nuts, springs, pressure plates, and pressure heads, achieves automatic clamping and fixing of the rear end of the insulating board, eliminating the need for manual support. This reduces operational difficulty and improves the safety and reliability of the cutting process. Attached Figure Description

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] Example 1:

[0031] like Figures 1-5 As shown, an insulation board wire cutting device includes a body 1. The main body of the body 1 has a forward-opening U-shaped structure. Longitudinal lead screws 11 are installed on both sides of the worktable surface of the body 1. Both longitudinal lead screws 11 are controlled by motors and are used to drive the lead screws to rotate forward and backward under the drive of the motors to realize the forward and backward movement of the moving frame 2. A metal wire 12 is vertically installed inside the body 1. The metal wire 12 is driven by an independent motor to reciprocate at high speed for wire cutting the insulation board. Protrusions 13 are provided on both side walls of the body 1. A fixing rod 14 is vertically fixed on the top of the protrusion 13. The fixing rod 14 is a cylindrical rod structure used to support the upper limit beam 4 and the lower limit beam 5 and ensure their positional stability. A limit nut 15 is screwed on the top of the fixing rod 14. The limit nut 15 is used to adjust the compression degree of the spring 3 so as to apply appropriate pressure to the upper limit beam 4. A spring 3 is sleeved on the outer surface of the fixing rod 14. When the spring 3 is compressed, it can apply a downward pushing force to the upper limit beam 4, thereby ensuring that the insulation board remains stably compressed during the cutting process.

[0032] like Figure 2 and Figure 3 As shown, the movable frame 2 has a U-shaped structure with an open front end. The movable frame 2 moves in the front-back direction when the slider is screwed into the surface of the longitudinal lead screw 11 and rotates in the same direction as the lead screw rotates. Both ends of the rear side of the upper surface of the movable frame 2 are provided with protruding plates 21. A transverse lead screw 22 is horizontally rotatably installed between the two protruding plates 21. The transverse lead screw 22 is used to drive the transverse slide plate 24 to move left and right. A motor 23 is fixed to the outside of one of the protruding plates 21. The output end of the motor 23 is connected to one end of the transverse lead screw 22 for driving the transverse lead screw 22 to rotate, thereby realizing the transverse movement of the transverse slide plate 24. With the front-back movement of the longitudinal lead screw 11, the position of the insulating plate can be flexibly adjusted on the two-dimensional plane to meet the needs of different cutting paths.

[0033] like Figure 3 and Figure 4 As shown, the transverse sliding plate 24 is screwed onto the surface of the transverse lead screw 22. The transverse sliding plate 24 can slide laterally when the transverse lead screw 22 rotates. The transverse sliding plate 24 is stepped in shape, which facilitates the stable placement of the insulating board. The upper surface of the transverse sliding plate 24 has a recessed mounting platform 241. The mounting platform 241 is a planar groove structure used to support the rear end of the insulating board, so that the front end of the insulating board is suspended in the air for the metal wire 12 to cut. The stepped structure of the transverse sliding plate 24 enables the insulating board to maintain stable support under different thickness specifications, thereby ensuring cutting accuracy.

[0034] like Figure 3 and Figure 4As shown, rotating bolts 25 are vertically and rotatably installed on both sides of the upper surface of the transverse sliding plate 24. The rotating bolts 25 pass through the transverse sliding plate 24 and can be adjusted up and down. A pressure plate 26 is screwed onto the surface of the rotating bolt 25. The pressure plate 26 extends forward in the horizontal direction, and a pressure head 27 is provided at the front end of the pressure plate 26 extending vertically downward. The two pressure heads 27 are located at the left and right ends of the rear side of the insulating plate, respectively. The rotating bolts 25 can drive the pressure plate 26 to move down, thereby pressing down and fixing the rear end of the insulating plate, effectively preventing the plate from moving or shaking during the cutting process, and ensuring the cutting accuracy and stability of the metal wire 12.

[0035] like Figure 5 As shown, the upper limit beam 4 and the lower limit beam 5 are placed above and below the insulating board to be cut, respectively. The upper limit beam 4 applies downward pressure through the action of the spring 3, and the lower limit beam 5 is fixed by being connected to the fixing rod 14 with bolts. The upper and lower limit beams form an upper and lower clamping structure to ensure that the insulating board is subjected to uniform force during the cutting process. A metal wire 12 is vertically arranged inside the machine body 1. The metal wire 12 is located between the upper limit beam 4 and the lower limit beam 5. The upper limit beam 4 is placed behind the metal wire 12, which can limit the warping deformation of the insulating board during the cutting process, thereby improving the cutting stability.

[0036] like Figure 5 As shown, a triangular extension frame 51 is provided at the center of the front side of the lower limit beam 5. The triangular extension frame 51 has an equilateral triangular structure. The metal wire 12 passes through the center of the triangular extension frame 51 to ensure the stability of the cutting path. Ball bearings 6 are installed at the three corners of the triangular extension frame 51. The ball bearings 6 can provide support when in contact with the insulating plate and allow the insulating plate to move freely. Ball bearings 6 are also evenly installed on the lower surface of the upper limit beam 4. The upper and lower sets of ball bearings 6 contact the upper and lower surfaces of the insulating plate respectively. The ball bearings 6 reduce frictional resistance while supporting the insulating plate, so that the insulating plate can move smoothly and be cut into any shape according to the set trajectory.

[0037] like Figure 5 As shown, a limiting nut 15 is screwed onto the top of the fixing rod 14. After the position of the limiting nut 15 is fixed, it can prevent the upper limit beam 4 from moving upward. A spring 3 is sleeved on the surface of the fixing rod 14. The spring 3 is located between the limiting nut 15 and the upper limit beam 4. It can continuously apply a downward pushing force to the upper limit beam 4, so that the upper limit beam 4 is pressed tightly against the surface of the insulating board. This prevents the insulating board from warping and bending due to its limited strength during the cutting process, thereby ensuring the stability and cutting accuracy of the metal wire 12 during cutting.

[0038] Example 2:

[0039] See Figures 1-5 The operation mode of an insulating board wire cutting device is as follows:

[0040] Before use, the operator first places the rear end of the insulation board to be cut on the surface of the transverse sliding plate 24 and makes the rear end of the insulation board fit against the mounting platform 241. At this time, the front end of the insulation board is suspended, which facilitates subsequent wire cutting. By rotating the rotating bolt 25, the pressure plate 26 screwed on the bolt surface can be moved down. The front end of the pressure plate 26 is provided with a pressure head 27. When the pressure head 27 contacts the rear end of the insulation board, it will gradually apply pressure, thereby fixing the rear end of the insulation board on the transverse sliding plate 24, realizing a stable clamping of the insulation board and preventing shaking during the cutting process.

[0041] After fixing, the motor drives the longitudinal lead screw 11 to rotate, and the longitudinal lead screw 11 threadedly drives the movable frame 2 to move in the front-to-back direction, so that the transverse lead screw 22 installed on the movable frame 2 moves back and forth as a whole; at the same time, the motor 23 drives the transverse lead screw 22 to rotate, and the transverse lead screw 22 pushes the transverse slide plate 24 to make lateral displacement, and the transverse slide plate 24 drives the insulating plate fixed thereon to achieve lateral adjustment; through the coordinated action of the longitudinal lead screw 11 and the transverse lead screw 22, the insulating plate can achieve arbitrary path movement in the horizontal direction, thereby cooperating with the metal wire 12 to complete the cutting of complex trajectories.

[0042] During the cutting process, the metal wire 12 is driven by an independent motor, enabling high-speed reciprocating linear motion. The motor heats the metal wire 12 with a constant current, so that the metal wire 12 has both mechanical cutting and thermal effects during the cutting process, thereby improving the cutting efficiency. Since the front end of the insulating plate is suspended, it is easy for the metal wire 12 to sag or warp during cutting. Therefore, an upper limit beam 4 and a lower limit beam 5 are set on the rear side of the metal wire 12 to work together. The upper limit beam 4 continuously applies downward pressure to the insulating plate through the spring 3, while the lower limit beam 5 is fixed to the fixing rod 14 by bolts to form a support below. The two form a stable clamping state, effectively avoiding deformation of the insulating plate due to uneven force.

[0043] To further enhance the stability of the cutting area, a triangular extension frame 51 is provided at the front end of the lower limit beam 5. Roller balls 6 are arranged at the three corners of the triangular extension frame 51. The roller balls 6 are in contact with the lower surface of the insulating plate, allowing the insulating plate to move freely while providing support. At the same time, multiple roller balls 6 are also installed on the lower surface of the upper limit beam 4. The roller balls 6 are in contact with the upper surface of the insulating plate, achieving bidirectional support and guidance. During the movement of the insulating plate, the roller balls 6 reduce frictional resistance by rolling, allowing the insulating plate to move smoothly along the set path without jamming due to excessive friction, thereby ensuring the stability and accuracy of the cutting trajectory of the metal wire 12.

[0044] Throughout the operation, the presence of the limit nut 15 ensures that the upper limit beam 4 does not move excessively upward, and the spring 3 remains under compression and provides downward thrust, ensuring that the insulating plate remains stable under appropriate pressure. At the same time, the U-shaped structure of the body 1 and the two side protrusions 13 effectively improve the overall rigidity, giving components such as the longitudinal lead screw 11, the transverse lead screw 22, and the fixing rod 14 good load-bearing capacity and shock resistance during operation. Through the above synergistic effect, the insulating plate can be stably, efficiently, and precisely cut into the required shape under the action of the metal wire 12, avoiding the cutting deformation and accuracy reduction problems caused by the plate being suspended in the air in traditional devices.

[0045] The working principle of this utility model is as follows: First, the rear end of the plate to be cut is placed on the surface of the mounting platform 241. Then, rotating the rotating bolt 25 can drive the pressure plate 26 on its surface to move down. The pressure head 27 is located above the mounting platform 241. At this time, the plate can be processed and fixed by the pressure head 27, so that the front side of the plate is in a suspended state. When the equipment is started, the metal wire 12 will move at high speed. The rotation of the longitudinal screw 11 controlled by the motor can then control the forward and backward movement of the moving frame 2. The rotation of the transverse screw 22 controlled by the motor 23 can control the transverse sliding plate 24 to move laterally, thereby realizing the multi-directional movement of the insulating plate. Cutting can be achieved by the movement of the relative metal wire 12.

[0046] During cutting, the front side of the board is suspended in the air. However, the insulation board has limited strength and may deform or bend, affecting the cutting quality. Therefore, an upper limit beam 4 and a lower limit beam 5 are added to support the board. Both the upper limit beam 4 and the lower limit beam 5 are installed on the fixing rod 14 and are positioned close to the rear of the metal wire 12. Since the limiting nut 15 is fixed, the spring 3 applies a downward force to the upper limit beam 4, which in turn applies a downward force to the insulation board. At the same time, the lower limit beam 5 is fixed to the fixing rod 14 with bolts. At this time, the lower limit beam 5 can support the insulation board. The metal wire 12 is placed at the center of the triangular extension frame 51. The three ball bearings 6 on the surface of the triangular extension frame 51 can effectively support the cutting area to ensure the stability of the insulation board during cutting. The ball bearings 6 can provide support without affecting the movement of the insulation board, allowing the insulation board to be moved flexibly and cut into any shape.

[0047] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
