Description

Technical Field

[0001] This utility model belongs to the technical field of electrolytic cutting equipment, and in particular relates to a circulating electrolytic grinding wire cutting processing device. Background Technology

[0002] In electrolytic cutting, the workpiece acts as the anode, connected to the positive terminal of a DC power supply, while the conductive grinding wheel acts as the cathode, connected to the negative terminal. During grinding, a certain grinding pressure is maintained between the two. The non-conductive abrasive particles protruding from the grinding wheel surface create an electrolytic gap between the workpiece surface and the conductive substrate of the grinding wheel, and electrolyte is supplied into this gap. Under the action of DC current, the metal on the workpiece surface generates ionic compounds and an anolyte film due to electrolysis. These electrolytic products are continuously scraped away by the rotating grinding wheel, exposing new metal surfaces and continuing the electrolytic process. Thus, the workpiece material is continuously removed, achieving the purpose of grinding.

[0003] Because the electrolytic grinding line of conventional wire EDM equipment can only work in a reciprocating manner, it is prone to wear in the commonly used cutting range. When the wear is excessive in a local area, the electrolytic grinding line needs to be replaced, which results in a waste of resources for reciprocating electrolytic grinding equipment.

[0004] To address these issues, we propose a circulating electrolytic grinding wire cutting processing device. Utility Model Content

[0005] The purpose of this invention is to solve the problem of resource waste in reciprocating electrolytic grinding equipment, and to propose a circulating electrolytic grinding wire cutting processing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A circulating electrolytic grinding wire cutting processing device includes a motor, a swing arm fixedly connected to the outside of the motor, a base oscillatingly connected to the root of the swing arm, a rotating shaft rotatably mounted on the swing arm, a conductive wheel fixedly connected to the outside of the rotating shaft, an insulating ring fixedly connected to the middle of the conductive wheel, a rotor of the motor fixedly connected to the rotating shaft, a brush movably pressed onto the upper part of the conductive wheel, a slide block slidably mounted on the head of the swing arm, a wire wheel rotatably mounted on the slide block, grinding wires sleeved on the conductive wheel and the wire wheel, a counterweight magnetically attracted to the swing arm, and a bolt threaded into the internal thread of the slide block, the bolt penetrating the slide block and movably inserted into the swing arm. Loosen the bolts to release the grinding wire from the sheave. After replacing the grinding wire, tighten the bolts to make the slide block drive the sheave to tighten the grinding wire. Use the motor to drive the shaft to rotate, which in turn drives the grinding wire to rotate. Use the brushes to supply power to the conductive wheel, which in turn supplies power to the grinding wire. The grinding wire cuts the target product. Use the counterweight to increase the pressure of the swing arm, which in turn increases the cutting pressure of the grinding wire on the product. Adjust the length of the swing arm lever by adjusting the counterweight to facilitate the electrolytic cycle cutting of the grinding wire.

[0008] Preferably, the swing arm includes an arm body, a rotating shaft rotatably connected to the arm body and passing through the arm body, a motor fixedly connected to the outside of the arm body, a connecting frame fixedly connected to the upper end of the arm body, a brush fixedly connected to the connecting frame, and the root of the arm body rotatably mounted on a machine base. The weight of the counterweight acts on the arm body, which in turn acts downwards on the conductive wheel and the wire wheel, which in turn act downwards on the grinding wire, pressing the grinding wire onto the target product for easy cutting.

[0009] Preferably, the slide includes a pair of slide rods. A threaded seat is fixedly mounted on the side of each slide rod, and a fixed shaft is fixedly connected to the side of each threaded seat. The reel is rotatably mounted on the fixed shaft, and the slide rod is slidably mounted on the arm. The arm guides the slide rod to slide, the fixed shaft guides the reel to rotate, and the threaded seat guides the bolt to move helically.

[0010] Preferably, the bolt includes a bolt body, one end of which is fixedly connected to a plug, which is movably inserted into the arm body. A first knob is fixedly connected to the end of the bolt body facing away from the plug. Turning the first knob rotates the bolt body, causing it to spiral along the threaded seat. The bolt body drives the slide to act on the grinding wheel, tightening the grinding wire and facilitating adjustment of the grinding wire tension.

[0011] Preferably, the counterweight includes a weight block, and a guardrail is symmetrically fixedly connected to the lower part of the weight block. The weight block and the guardrail are movably fitted onto the arm body. A threaded shell is installed inside the threaded shell, and a magnet block is fixedly connected to the lower part of the threaded shell. The magnet block is magnetically matched with the arm body. By using the magnet block to magnetically attract the weight block to the arm body, the weight block is held on the arm body, which facilitates the alignment of the counterweight block and the swing arm.

[0012] Preferably, the counterweight further includes a second knob, which is fixedly connected to the upper end of the threaded housing. The second knob is used to increase the length of the turning lever of the threaded housing.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Loosen the bolts to loosen the grinding wire from the sheave. After replacing the grinding wire, tighten the bolts to make the slide block drive the sheave to tighten the grinding wire. Use the motor to drive the shaft to rotate, which in turn drives the grinding wire to rotate. Use the brushes to supply power to the conductive wheel, which in turn supplies power to the grinding wire. The grinding wire cuts the target product. Use the counterweight to increase the pressure of the swing arm and the cutting pressure of the grinding wire on the product. Adjust the length of the swing arm lever by adjusting the counterweight to facilitate the electrolytic cycle cutting of the grinding wire.

[0015] 2. Turning the first knob causes the bolt body to rotate, making the bolt body spiral along the thread seat. The bolt body drives the slide to act on the wire wheel, making the wire wheel taut and facilitating the adjustment of the tension of the grinding wire. Attached Figure Description

[0025] like Figure 1 and 3 As shown, the slide block 3 includes a slide rod 31, which has a pair. A threaded seat 33 is fixedly installed on the side of the slide rod 31, and a fixed shaft 32 is fixedly connected to the side of the threaded seat 33.
