Description

Technical Field

[0001] This invention relates to the technical field of wire cutting, specifically to an adjustable slow wire cutting machine tool. Background Technology

[0002] A slow-wire wire EDM machine is an electrical discharge machining (EDM) device. Its core principle is to achieve high-precision cutting by corroding conductive materials through electrical discharge. The specific process is as follows: a thin copper wire is used as an electrode and moved slowly; simultaneously, a high-voltage pulsed current is applied to the surface of the aluminum mold, initiating an electrical discharge; the localized high temperature generated during the discharge melts or vaporizes the aluminum mold, and then deionized water coolant washes away the debris, thus completing the non-contact cutting. The key feature of this machine tool is its "slow-wire" design, which effectively avoids copper wire breakage, ensures micron-level precision, and can handle complex contours.

[0003] In the wire EDM process of aluminum profiles, the aluminum debris generated during processing needs to be manually cleaned by the operator after the equipment stops running. This process is not only time-consuming and labor-intensive, but also increases the workload. If the debris accumulates, it may clog the filter holes, causing the cooling fluid circulation to fail. To address this problem, a design scheme for an adjustable slow wire EDM machine tool is proposed. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an adjustable slow wire EDM machine tool, which has the following beneficial effects: 1. This adjustable slow wire EDM machine tool, during the wire cutting process, generates waste chips that fall into the collection section under gravity; simultaneously, the resulting carbonized deposits also fall into the collection section for collection. This prevents the accumulation of waste chips and carbonized deposits inside the machine tool, reducing the impact on normal equipment operation. It achieves centralized cleaning of waste chips and carbonized deposits generated during processing, significantly saving cleaning time, reducing the operator's labor intensity, and thus improving the machine tool's working efficiency and service life.

[0018] 2. After cutting, this adjustable slow wire EDM machine allows the user to easily remove the cut workpiece when the baffle descends to be flush with the mounting plate. Once the workpiece is removed, the baffle continues to descend, triggering the transmission mechanism, which in turn raises the second lifting mechanism, causing the collection section to rise synchronously. This allows the user to easily remove the collection section from the slot for cleaning away waste chips and carbonized deposits. After cleaning, the baffle is raised back to its original position, the transmission mechanism resets, and the second lifting mechanism lowers the collection section to its initial position, preparing it for the next processing cycle.

[0019] 3. In this adjustable slow wire EDM machine, the waste copper wire generated during the wire cutting process is collected by a collection box. After the cutting is completed, the lifting mechanism 1 drives the baffle to descend while driving the lifting mechanism 3 to work. The lifting mechanism 3 drives the collection box to rise, and the waste copper wire in the collection box is compressed, reducing the space occupied.

[0020] 4. In this adjustable slow-speed wire EDM machine, during the continuous output of scrap copper wire, motor two drives the eccentric block to rotate. The rotation of the eccentric block causes slider three to slide along track three, with spring three acting as a buffer during this process. Slider three drives the cutter body to move, and the cutter body, in conjunction with gear two, cuts the scrap copper wire into small segments for subsequent processing. This improves the machine tool's waste processing capacity, making waste cleaning and recycling more efficient. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] During wire EDM of aluminum profiles, the aluminum chips generated during processing require manual cleaning of the filter screen by the operator after the equipment stops running. This process is not only time-consuming and labor-intensive, but also increases the workload. If chips accumulate, they may clog the filter holes, causing the cooling fluid circulation to fail. This application proposes a method where, during wire EDM, the generated chips fall into the collection section 400 under gravity; simultaneously, the formed carbonized deposits also fall into the collection section 400 for collection. This avoids the accumulation of chips and carbonized deposits inside the machine tool, reducing the impact on normal equipment operation. It achieves centralized cleaning of chips and carbonized deposits generated during processing, significantly saving cleaning time, reducing the operator's workload, and thus improving the machine tool's efficiency and service life.

[0025] As attached Figure 1-10As shown, this embodiment provides an adjustable slow wire EDM machine tool, including a base 110, a housing 120 disposed on the top of the base 110, a back plate 140 disposed on the top of the housing 120, side plates 130 symmetrically disposed on the back plate 140, a mounting plate 160 disposed on the top of the housing 120, and a baffle 170 slidably connected to the side plate 130. The two side plates 130, the back plate 140, and the baffle 170 surround the mounting plate 160. The mounting plate 160 is used to restrict the workpiece to be processed. A lifting mechanism one is provided on the side plate 130, which is used to control the lifting and lowering of the baffle 170, making it convenient for the user to operate the workpiece. A lifting mechanism two is provided on the back plate 140, which is provided with a collecting part 400. A transmission mechanism is provided on the side plate 130, which is used to transmit the transmission power of the lifting mechanism one to the lifting mechanism two.

[0026] Specifically, the collection section 400 is rectangular and has a trough for collecting waste. A rectangular notch (not shown in the attached diagram) can be made in the middle of the collection section 400. When the collection section 400 rises, the lower guide wire component will not obstruct it. After the workpiece on the mounting plate 160 is removed, when waste needs to be cleaned, the lifting mechanism one lowers the baffle 170 at a constant speed. When the baffle 170 descends below the plane of the mounting plate 160, it triggers the transmission mechanism. The transmission mechanism transmits the power from the lifting mechanism one to the lifting mechanism two, causing the collection section 400 to rise synchronously. After the collection section 400 rises, the user can easily remove it from the machine tool and thoroughly clean the waste chips and carbonized deposits in the trough of the collection section 400.

[0027] As attached Figure 3 As shown, the lifting mechanism includes a second screw 610 and a second slider 620. One end of the second screw 610 is connected to the side plate 130. The second slider 620 is threadedly connected to the outer wall of the second screw 610 and is fixedly connected to the baffle 170. A second slider 620 is also provided in one of the side plates 130, and a groove is provided to restrict the sliding of the second slider 620. Therefore, the baffle 170 connects the two second sliders 620, ensuring the stability of the sliding. Driving the rotation of the second screw 610 causes the screw 610 to be threadedly connected to the second slider 620, and the second slider 620 moves linearly within the side plate 130.

[0028] As attached Figure 3 and 4As shown, the lifting mechanism 2 includes: a second track 550 and a third shaft 530. The second track 550 is fixed to one side of the back plate 140. A first slider 510 is slidably connected to the second track 550. The first slider 510 is connected to the collecting part 400. The first slider 510 is "L" shaped, with one side sliding on the second track 550 and the other side used to support the collecting part 400. The third shaft 530 is set on the side plate 130. A first gear 540 is fixed to the outer side wall of the third shaft 530. The first gear 540 is meshed with the first slider 510.

[0029] Specifically, when the transmission mechanism transmits the power from lifting mechanism one to lifting mechanism two, shaft three 530 will begin to rotate clockwise under the action of the power. The rotation of shaft three 530 drives gear one 540, which is fixed on the outer wall, to rotate. Since gear one 540 is meshed with slider one 510, the rotation of gear one 540 will drive slider one 510 to slide linearly on track two 550. Because slider one 510 is connected to and supports the collecting part 400, the sliding of slider one 510 on track two 550 will cause the collecting part 400 to rise or fall synchronously.

[0030] As attached Figure 3-7 As shown, the transmission mechanism includes a plate 710, a second spring 720, and a rod 730. The plate 710 is slidably connected to the side plate 130. The second spring 720 is disposed between the plate 710 and the back plate 140. The rod 730 is fixed to the top of the plate 710. A pressure part 740 is fixed to one side of the rod 730. A commutator 630 is fixed to the top of the second screw 610. A shaft 640 is fixed to the input end of the commutator 630. A worm gear 650 is fixed to the outer side wall of the shaft 640. A shaft 520 is rotatably connected between the two side plates 130. The shaft 520 is slidably connected to the shaft 530. A worm wheel 660 is fixed to one end of the shaft 520, and a first spring 560 is sleeved on the other end. A block 570 is fixed to the outer side wall of the shaft 530.

[0031] Specifically, the contact surface between one side of the plate 710 and the second slider 620 is an inclined surface. When the second slider 620 slides to below the mounting plate 160, it will squeeze the inclined surface, causing the plate 710 to move backward and drive the rod 730 to move, so that the pressure part 740 squeezes one side of the block 570. The block 570 drives the third shaft 530 to move on the second shaft 520. At this time, the first gear 540 engages with the first slider 510, and the first spring 560 is compressed. Meanwhile, the rotation of screw 2 610 is transmitted to shaft 4 640 through commutator 3 630. Shaft 4 640 drives worm 650 to rotate. Worm 650 meshes with worm wheel 660, which in turn drives shaft 2 520 to rotate. Shaft 2 520 drives shaft 3 530 connected to it to rotate (the two can be connected by a spline). Gear 1 540 on shaft 3 530 drives slider 1 510 to slide on track 2 550, thereby realizing the rise of collection section 400. After the waste in the collection section 400 is cleaned up, the lifting mechanism 1 raises the baffle 170. At this time, the slider 2 620 stops pressing the plate 710, the spring 2 720 pushes the plate 710 back to its original position, and the rod 730 and the pressure part 740 also return to their original positions. The elastic force of the spring 1 560 causes the shaft 3 530 to move in the opposite direction on the shaft 2 520. The gear 1 540 disengages from the slider 1 510, and the collection section 400 descends to its initial position.

[0032] As attached Figure 8-10 As shown, a collection box 310 is slidably connected to the top of the base 110, a frame 320 is fixed to the top of the base 110, a motor 670 is fixed to one side of the frame 320, the motor 670 is connected to the shaft 640, and a lifting mechanism 3 for controlling the lifting of the collection box 310 is provided on the top of the base 110.

[0033] Specifically, when motor 670 starts, it drives shaft 640 to rotate, which in turn causes collection section 400 to rise for waste cleaning through a series of transmissions. Lifting mechanism 3 starts working, driving collection box 310 to rise, compressing the copper wires inside collection box 310, reducing the need for users to collect copper wires multiple times, and facilitating centralized processing.

[0034] As attached Figure 8-10As shown, the lifting mechanism three includes a screw 350, a top plate 330, and a track 370. The screw 350 is rotatably connected to the top of the base 110, and the outer side wall of the screw 350 is threadedly connected to the base plate 360. The top plate 330 is located between two frames 320. A commutator 380 is installed inside the top plate 330. The output end of the commutator 380 is fixedly connected to the screw 350, and the input end is fixedly connected to the shaft 390. A commutator 391 is installed inside the frame 320. The two output ends of the commutator 391 are fixedly connected to the shaft 390 and the shaft 640, respectively, and the input end is fixedly connected to the output end of the motor 670. The track 370 is fixed to the top of the base 110. A pressure block 340 is installed at the bottom of the top plate 330.

[0035] Specifically, when motor 670 starts, power is transmitted to shaft 390 via commutator 391, and shaft 390 then transmits the power to commutator 380. Commutator 380 drives screw 350 to rotate. Since screw 350 is threadedly connected to base plate 360, the rotation of screw 350 causes base plate 360 ​​to move upward along screw 350. Simultaneously, collection box 310 rises stably under the constraint of track 370. As collection box 310 rises, pressure block 340 at the bottom of top plate 330 gradually approaches the copper wire inside collection box 310. When collection box 310 rises to a certain position, pressure block 340 applies pressure to the copper wire inside, compressing it, reducing the space occupied by the copper wire, decreasing the frequency of multiple collections, and concentrating the copper wire together for easier subsequent centralized processing. This makes transportation and recycling more convenient and efficient.

[0036] As attached Figure 1-10 As shown, a connecting rod 810 is fixed on one side of the base plate 360, a disc 820 is provided on the top of the connecting rod 810, and a through groove that matches the disc 820 is provided on the bottom of the collection box 310. The top of the housing 120 is equipped with an X and Z axis moving mechanism 200, and a slide 150 is provided on the X and Z axis moving mechanism 200. A cutting mechanism is provided at the waste copper wire outlet on the slide 150. The cutting mechanism includes: a track 3 940, a spring 3 950 and a connecting plate 970. The track 3 940 is fixed to one side of the slide 150, and a slider 3 930 is slidably connected to the track 3 940. The spring 3 950 is fixed between the slider 3 930 and the track 3 940, and a blade 960 is fixed to one side of the slider 3 930. The connecting plate 970 is fixed to one side of the slide 150, and a gear 2 980 is rotatably connected to the connecting plate 970. The gear 2 980 meshes with the blade 960 and the collection box 310 (the gear structure is not shown in the attached drawings).

[0037] Specifically, when the collection box 310 rises to the waste wire discharge port, it meshes with gear 2 980 and drives gear 2 980 to rotate. At this time, gear 2 980 meshes with one side of the cutter body 960, causing the cutter body 960 to descend and cut the waste copper wire into the collection box 310, thus completing the collection and processing of waste copper wire.

[0038] The X and Z axis moving mechanism 200 can precisely control the position of the slide 150, ensuring the accuracy and quality of wire EDM machining. This is existing technology and will not be elaborated further. The coordinated operation of the collection unit 400 and the collection box 310 makes waste cleaning and recycling more convenient, greatly improving the overall performance of the machine tool.

[0039] Once the collection box 310 is full of waste copper wire, slide the collection box 310 to the top position of the disc 820. At this time, the base plate 360 ​​rises, which will drive the connecting rod 810 to rise synchronously, thereby causing the disc 820 to push the compressed waste copper wire in the collection box 310 out of the box, so that users can collect waste copper wire more conveniently.

[0040] As attached Figure 8-10 As shown, in order to reduce the area occupied by waste copper wire in the collection box 310 and facilitate subsequent collection by users, the cutting mechanism also includes a second motor 910. The second motor 910 is fixed to one side of the slide 150, and the output shaft of the second motor 910 is fixed with an eccentric block 920.

[0041] Specifically, when motor 2 910 starts, its output shaft drives eccentric block 920 to rotate eccentrically. The eccentric rotation of eccentric block 920 compresses slider 3 930, causing slider 3 930 to move linearly on track 3 940. This linear movement of slider 3 930 further drives the cutter body 960 downwards, thus cutting the waste copper wire. This makes the cutting process more stable. Simultaneously, spring 3 950 acts as a buffer and reset mechanism during the movement of slider 3 930, ensuring that the cutter body 960 accurately returns to its initial position, preparing for the next cut.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
