Description

Technical Field

[0001] This utility model belongs to the field of cutting equipment technology, and relates to a cutting machine, specifically a single-head wire cutting machine. Background Technology

[0002] Diamond wire EDM (DCE) machines are highly efficient and precise cutting tools primarily used for cutting various hard materials. They employ a unidirectional or reciprocating cyclic motion of the diamond wire, creating a relative grinding motion between the wire and the workpiece to achieve the cutting purpose. When processing non-conductive materials requiring wire EDM, electrical discharge machining (EDM) becomes ineffective. In this case, diamond wire EDM machines demonstrate their advantages, capable of cutting both conductive and non-conductive materials (as long as their hardness is less than that of diamond wire). Therefore, diamond wire EDM machines are widely used for cutting various metallic and non-metallic composite materials, such as ceramics, glass, rocks, gemstones, jade, meteorites, monocrystalline silicon, silicon carbide, polycrystalline silicon, refractory bricks, epoxy boards, ferrites, PCBs, as well as building materials, dental materials, and bio- and biomimetic composite materials. They are particularly suitable for cutting high-hardness, high-value, and easily breakable brittle materials.

[0003] Carbon fiber tubes, also known as carbon fiber tubes (or carbon tubes, carbon fiber tubing), are made by pre-impregnating carbon fiber composite materials with styrene-based polyester resin and then pultruding (winding) them through heat curing. They have advantages such as high strength, long lifespan, corrosion resistance, light weight, and low density. When conventional cutting equipment (such as milling machines) is used to process carbon fiber tubes, the large contact area between the machine and the carbon fiber tube results in a large amount of fine chips, which not only affects the precision of the carbon fiber tube but may also cause the chips to be scattered, potentially affecting the health of employees. Wire EDM machines can reduce the amount of fine chips generated and are therefore used in the processing of carbon fiber tubes.

[0004] Chinese utility model patent application number 202420059761.3 discloses a swing-type lifting diamond wire cutting machine for stone. The machine includes: a frame; a first cutting component disposed on one side of the frame; a second cutting component disposed on the other side of the frame and connected to the first cutting component via a diamond wire; a first lifting motor for controlling the lifting of the first cutting component; and a second lifting motor for controlling the lifting of the second cutting component. During cutting, the first and second lifting motors alternately control the descent of the cutting components, causing them to swing downwards continuously. This reduces the contact area between the diamond wire and the stone, lowers the diamond wire wear, and improves stone cutting efficiency. This type of diamond wire cutting machine is typically suitable for large, hard stones but not for carbon fiber tubes; moreover, the small cross-sectional area of ​​carbon fiber tubes means that processing only one tube will reduce the efficiency of the wire cutting machine. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency single-head wire cutting machine for carbon fiber tube processing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a single-head wire cutting machine, comprising:

[0007] Support base;

[0011] Furthermore, the side plate is also equipped with a drive wheel motor that is connected to the drive wheel via a transmission belt.

[0012] Furthermore, the cutting assembly also includes a shield mounted on the side plate and located outside the drive wheel, the driven wheel and the tension adjusting wheel, with a lower opening in the shield.

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0024] like Figure 1 and Figure 2The single-head wire cutting machine 2 shown mainly includes a supporting base 21, a material loading assembly 22, and a cutting assembly 23.

[0025] The support base 21 can adopt a conventional structure, as long as it can support the material loading assembly 22 and the cutting assembly 23. In this embodiment, it includes a receiving box, multiple support legs (at least three, but preferably seven, with three legs installed on each of the two long sides of the bottom of the receiving box and one leg installed at the center of the bottom of the receiving box), multiple parallel reinforcing columns installed inside the receiving box (preferably 2 to 5 columns installed on the upper and lower parts of the receiving box), and a waste collection box disposed inside the receiving box.

[0026] The material carrier assembly 22 includes a carrier plate 223 slidably mounted on a support base 21 and a carrier 224 mounted on the carrier plate 223 for placing multiple carbon fiber tubes. This allows the carrier 224 carrying the carbon fiber tubes to be placed on the carrier plate 223 and positioned manually or by a robot, and the carrier plate 223 to be moved to its processing position. In this embodiment, the material carrier assembly 22 also includes multiple pad tubes 221 (usually two) mounted on the support base 21 and arranged in parallel, carrier plate slide rails 222 mounted one-to-one on the pad tubes 221, a slider mounted on the bottom surface of the carrier plate 223 and cooperating with the carrier plate slide rails 222, a support seat 224' mounted on the support base 21, a carrier plate drive screw 225 mounted on the support seat 224' and connected to the carrier plate 223 via an adapter plate (the carrier plate drive screw 225 passes through the adapter plate and is threadedly connected to it), and a carrier plate drive motor mounted at the end of the carrier plate drive screw 225 for driving its rotation. When the carrier drive motor is working, it can drive the carrier drive screw 225 to rotate synchronously, thereby driving the carrier 223 to move horizontally relative to the carrier slide rail 222, thus greatly adjusting the position of the carrier 224 and making it move back and forth between the loading position and the processing position.

[0027] In this embodiment, the material loading assembly 22 also includes multiple carrier pads 2231 (typically 2 to 6 carrier pads 2231 are formed on the upper surface of the carrier plate 223 and arranged in parallel; they are located below the carrier 224, but usually near the edge of the carrier 224; the forming method can be conventional, such as installation by bolts or other fasteners), a carrier fixing block 2232 set on the upper surface of the carrier plate 223 and extending in a direction perpendicular to the gantry 231, and a first carrier moving block 2233, a second carrier moving block 2234, and a third carrier moving block 2235 that are adjustablely installed on the upper surface of the carrier plate 223 and cooperate with the other three sides of the carrier 224. The adjustment methods of the first vehicle movement block 2233, the second vehicle movement block 2234, and the third vehicle movement block 2235 are basically the same. All three involve mounting a certain number of cylinders on the upper surface of the carrier plate 223, connecting each cylinder to its corresponding first vehicle movement block 2233, second vehicle movement block 2234, and third vehicle movement block 2235. This allows the first vehicle movement block 2233, second vehicle movement block 2234, or third vehicle movement block 2235 to move. (The difference is that the first vehicle movement block 2233 and third vehicle movement block 2235 are driven by two cylinders, while the second vehicle movement block 2234 consists of two blocks, each freely adjustable.) (Driven by a cylinder); The carrier fixing block 2232, the first carrier moving block 2233, the second carrier moving block 2234 and the third carrier moving block 2235 need to be set around the carrier 224. When the corresponding cylinders work, the carrier fixing block 2232, the first carrier moving block 2233, the second carrier moving block 2234 and the third carrier moving block 2235 can abut against the four sides of the carrier 224, thereby clamping the carrier 224 for subsequent wire cutting (when the wire cutting is completed, the corresponding cylinder is reset, and this carrier 224 is removed and replaced with another carrier 224 (carrying multiple carbon fiber tubes to be processed)). The carrier 224 is formed by clamping multiple carrier units from left to right or by fixing multiple carrier units from left to right (such as by welding or integral molding). Each carrier unit is generally in the shape of a long strip similar to a carbon fiber square tube. Its lower part is hollow to reduce weight, and its upper part has a mounting groove that matches the carbon fiber square tube to accommodate the carbon fiber square tube (the inner wall of the mounting groove is provided with extrusion strips extending in opposite directions). The front and rear ends form stepped parts with different structures (through holes and grooves are provided in the stepped parts), so that it can also be used for subsequent steps and tightly clamp the carbon fiber square tube.

[0028] Cutting component 23, such as Figure 3 and Figure 4As shown, it includes a gantry 231 slidably mounted on a support base 21 and spanning a loading assembly 22, a side plate 235 slidably mounted on the side of the gantry 231 and corresponding to the loading assembly 22, at least one driven wheel 237 mounted on the side plate 235, a driving wheel 238 mounted on the side plate 235, a tension adjusting wheel 239 mounted on the side plate 235 and cooperating with the driven wheel 237 and the driving wheel 238, and a diamond cutting wire 230 wound around the driving wheel 238, the driven wheel 237 and the tension adjusting wheel 239. In this embodiment, the sliding method of the gantry 231 on the support base 21 can adopt the existing conventional method (not shown in the figure), as long as the gantry 231 can slide on the support base 21; for example, a slide rail can be installed on the support base 21, a slider that cooperates with the slide rail can be installed on the gantry 231, a reinforcing plate can be provided on the support base 21, and a hydraulic cylinder connected to the gantry 231 can be installed on the reinforcing plate.

[0029] In this embodiment, a waist-shaped hole 2351 is provided on the side plate 235. The tension adjusting wheel 239 is adjustablely installed in the waist-shaped hole 2351. An adjusting cylinder 2352 connected to the tension adjusting wheel 239 is installed on the side plate 235 to drive its movement. When the adjusting cylinder 2352 is working, it can drive the tension adjusting wheel 239 to move in the waist-shaped hole 2351, thereby adjusting the tension of the diamond cutting wire 230. A drive wheel drive motor 2381 connected to the drive wheel 238 via a transmission belt (not shown in the figure) is also installed on the side plate 235 (the drive wheel drive motor 2381 and the drive wheel 238 are usually located on opposite sides of the side plate 235). When the drive wheel drive motor 2381 is working, it can drive the drive wheel 238 to rotate, thereby driving the diamond cutting wire 230 to rotate cyclically. There are two driven wheels 237, located at the two corners of the lower part of the side plate 235; the driving wheel 238 and the tension adjusting wheel 239 are located at the two corners of the upper part of the side plate 235. This can maximize the length of the diamond cutting wire 230 wound on them, which can not only cut multiple carbon fiber tubes at the same time, but also increase the length of the diamond cutting wire, thereby extending its service life.

[0030] In this embodiment, the cutting assembly 23 also includes a shield 236 mounted on the side plate 235 and located outside the drive wheel 238, driven wheel 237 and tension adjusting wheel 239, with a lower opening in the shield 236.

[0031] The cutting assembly 23 also includes a guide rod 2310 mounted on the side plate 235 via multiple mounting brackets 2311 (preferably two), a transverse slider 2312 slidably mounted on the guide rod 2310, a rodless cylinder 2313 mounted on the transverse slider 2312 to drive it to move on the guide rod 2310, and a paddle block 2315 mounted on the lower end of the rodless cylinder 2313. After wire cutting is completed, the rodless cylinder 2313 operates to drive the paddle block 2315 to move linearly along the guide rod 2310, thereby pushing the cut waste to one side to fall into the aforementioned waste collection box. The cutting assembly 23 also includes a cutting fluid spray nozzle 2300 and an air blowing pipe 2301 extending to cooperate with the diamond cutting wire 230 to cool the diamond cutting wire 230 and prevent the generation of cutting dust.

[0032] In this embodiment, the cutting assembly 23 also includes a transition pad post 232 installed on the side of the gantry 231, a side plate slide rail 233 installed on the transition pad post 232, and a side plate slider 234 installed on the side plate 235 and cooperating with the side plate slide rail 233. The driving method here is the same as that of the carrier plate 223, which is also a combination of screw and motor. Its installation position is not limited, as long as it can drive the side plate 235 to move up and down relative to the transition pad post 232.

[0033] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
