Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine technology, specifically to a wire cutting device with a coolant recovery structure. Background Technology

[0002] A wire EDM machine is an electrical discharge machining device that uses a continuously moving fine metal wire to perform pulsed spark discharge on the workpiece to remove metal and achieve metal cutting and shaping. During the processing and use of a wire EDM machine, it is necessary to use wire EDM fluid (coolant) to reduce the friction between the metal and the screen during cutting, protect the machine's cutting tools from wear, suppress heat growth, and reduce thermal deformation. Wire EDM fluid (coolant) is generally used for fast wire EDM and medium wire EDM, while slow wire EDM usually uses pure water.

[0003] The current method of using coolant in wire EDM machines involves spraying it onto the surface of the workpiece and then discharging it together with the metal shavings generated during processing. The metal shavings and coolant are then sorted and recycled in a unified manner to achieve reuse. This method is cumbersome, time-consuming, and requires more manpower, material resources, and financial resources, making it very inconvenient. Utility Model Content

[0004] Based on the above description, this utility model provides a wire cutting machine with a coolant recovery structure to solve the problem that the existing wire cutting machine process of centralized discharge and recovery of coolant and metal waste is costly in terms of manpower, material resources and financial resources.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wire cutting device with a coolant recovery structure includes a machine body, a cutting arm and a processing table installed on the outside of the machine body. A flow guide structure for collecting coolant is installed on the outside of the machine body. The drain end of the flow guide structure is connected to a pressurization pipe. The other end of the pressurization pipe is equipped with a bamboo tube for guiding the coolant out. The bamboo tube, the pressurization pipe and the flow guide structure allow the coolant to circulate around the processing table.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a mounting groove is provided in the center of the surface of the machine body near the processing table. One end of the mounting groove passes through the machine body, and the other end is semi-circular.

[0008] Furthermore, the flow guiding structure includes a support part, a flow guiding bucket, and a filter screen. The support part has the same shape and size as the mounting groove and is inserted into the inner side of the mounting groove. The support part is hollow inside, and an opening is provided at the end of the inner wall away from the machine body.

[0009] Furthermore, the flow guide bucket is integrally formed on the surface of the support portion and extends toward the inner side of the support portion, and the filter screen is fixedly connected to the inner side of the flow guide bucket.

[0010] Furthermore, the axis of the guide bucket coincides with the axis of the semi-circular end of the support portion, and the smaller diameter end of the guide bucket faces the inner side of the support portion.

[0011] Furthermore, a double-through connector is provided through the side of the support part near the cutting arm, with the two ends of the double-through connector facing the inner and outer sides of the support part respectively, and the bamboo tube is installed at the end of the double-through connector away from the support part.

[0012] Furthermore, the pressurization pipeline includes a water pump, an inlet pipe, and a drain pipe. The water pump is installed inside the support, the inlet pipe is installed between the smaller diameter end of the guide bucket and the inlet end of the water pump, and the drain pipe is installed between the outlet end of the water pump and the other end of the double-connector.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] This invention utilizes a flow-guiding structure, combined with a pressurized pipeline and a bamboo-joint tube. After use, the coolant, having rinsed the workpiece, enters the flow-guiding structure for direct filtration. The filtered coolant then passes through the pressurized pipeline and bamboo-joint tube to rinse the workpiece again, creating a cycle for reuse. Metal shavings generated during filtration remain on the filter screen of the flow-guiding structure for separate processing later. The entire coolant recycling process is simple and fast, allowing for direct recycling and automation, effectively reducing the consumption of manpower, material resources, and financial resources, and controlling the cost of coolant recycling and processing.

[0023] Please see Figure 1-4 The present invention relates to a wire cutting device with a coolant recovery structure, comprising a machine body 1, a cutting arm 2 installed on the outside of the machine body 1, and a processing table 3. A flow guide structure 4 for collecting coolant is installed on the outside of the machine body 1. A pressurization pipe 6 is connected to the drain end of the flow guide structure 4. A bamboo joint pipe 7 for guiding the coolant out is installed at the other end of the pressurization pipe 6. The bamboo joint pipe 7, the pressurization pipe 6, and the flow guide structure 4 are used to circulate the coolant around the processing table 3.

[0024] Please see Figure 2 An installation groove 11 is provided in the center of the surface of the machine body 1 near the processing table 3. One end of the installation groove 11 passes through the machine body 1, and the other end is semi-circular. The semi-circular end of the installation groove 11 is adapted to the cone shape of the guide bucket 42, which provides installation space for the guide bucket 42 while reducing the waste of space.

[0025] Please see Figure 2The flow guiding structure 4 includes a support part 41, a flow guiding hopper 42, and a filter screen 43. The support part 41 has the same shape and size as the mounting groove 11 and is inserted into the inner side of the mounting groove 11.

The entire coolant recycling process is simple and fast. The coolant can be directly recycled and reused. The process is automated, which effectively reduces the consumption of manpower, material resources and financial resources, and controls the cost of coolant recycling and treatment.

[0026] Please see Figure 4 A double-connector 5 is provided through the side of the support part 41 near the cutting arm 2. The two ends of the double-connector 5 face the inner and outer sides of the support part 41 respectively. The bamboo tube 7 is installed at the end of the double-connector 5 away from the support part 41. The bamboo tube 7 can be bent to adjust the angle of use, so that the filtered coolant can directly rinse the workpiece on the surface of the processing table 3 through the bamboo tube 7, forming a cycle.

[0027] Please see Figure 4 The booster pipeline 6 includes a water pump 61, an inlet pipe 62, and a drain pipe 63. The water pump 61 is installed inside the support part 41. The inlet pipe 62 is installed between the smaller diameter end of the guide bucket 42 and the inlet end of the water pump 61. The drain pipe 63 is installed between the outlet end of the water pump 61 and the other end of the double connector 5. The water pump 61 is a BSP48180 miniature self-priming pressure water pump. The water pump 61 draws the filtered coolant in the guide bucket 42 through the inlet pipe 62 and provides power so that the coolant can be sprayed through the drain pipe 63 and the bamboo joint pipe 7.
