Description

Technical Field

[0001] This utility model relates to the field of EDM technology, specifically to an EDM oil discharge mechanism. Background Technology

[0002] An electrical discharge machining (EDM) machine is a type of machining equipment primarily used for electrical discharge machining. It is widely used in the manufacture of various metal molds and mechanical equipment. EDM is a special machining method that uses the electro-erosion effect generated by pulsed discharge between two electrodes immersed in a working fluid to remove conductive materials. It is also known as electrical discharge machining or electro-erosion machining, and is abbreviated as EDM in English.

[0003] When modern EDM machines are in operation, the oil needs to be drained. Traditionally, this is done by receiving the oil through a box structure with a filter screen inside. However, this filtration is not thorough enough, resulting in poor oil reuse. Furthermore, the fixed filter screen makes it difficult to clean, leading to clogging. Utility Model Content

[0004] The purpose of this utility model is to provide an oil draining mechanism for EDM machines, in order to solve the problems mentioned in the background art. When EDM machines are in operation, oil needs to be drained. Traditionally, the oil is received by a box structure with a filter screen fixed inside the box. However, the filtration is not thorough enough, resulting in poor reuse of the oil. At the same time, the fixed screen structure makes it difficult to clean, which easily leads to blockage.

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

[0006] A discharge mechanism for an EDM machine includes a main support box. Side mounting strips are horizontally and symmetrically welded to both sides of the main support box. Fixed through holes are evenly distributed on the top surface of each side mounting strip. A side through groove is horizontally and evenly distributed on one side of the main support box. A sealing cover plate is horizontally engaged with the inner side of the side through groove. Fixed screws are symmetrically inserted into the side of the sealing cover plate. A mating cylinder is horizontally fixed to one side of the sealing cover plate. A bottom fixing box is fixed to the bottom surface of the main support box. A guide tube is horizontally inserted into the side of the bottom fixing box. Fixed screw holes are symmetrically distributed on the inner side of the side through groove. A bottom... The main support box has a through hole. A limiting groove is evenly and horizontally formed on its inner wall. A supporting inner frame is horizontally inserted into the inner side of the main support box. A side-clamping groove is horizontally formed on the inner side of the supporting inner frame. A scraper inner plate is horizontally clamped into the inner side of the side-clamping groove. A bottom fixing frame is horizontally fixed to the inner side of the supporting inner frame. A supporting frame body is horizontally clamped to the inner side of the supporting inner frame. A filter plate body is horizontally fixed to the inner side of the supporting inner frame. An outer clamping frame is horizontally fixed to the outer side of the supporting inner frame. A pump body is fixedly installed on the inner side of the bottom fixing box. A connecting top pipe is fixedly connected to the input end of the pump body.

[0007] In a preferred embodiment of this utility model, the top surface of the main support box is open, and there are two mounting side strips. The two mounting side strips are fixedly and symmetrically arranged on both sides of the top of the main support box, and the fixing through holes are arranged in a straight line at the center line of the top surface of the mounting side strips.

[0008] In a preferred embodiment of this utility model, there are multiple side through grooves, and the multiple side through grooves are arranged in parallel and superimposed on each other. The side through grooves are connected to the interior of the main support box. The fixing screws are symmetrically inserted into the side of the sealing cover plate near the through holes at both ends, and the insertion end is fixedly connected to the inner side of the fixing screw hole with a corresponding thread.

[0009] As a preferred embodiment of this utility model: one end of the matching cylinder is fixedly set at the center of the side of the sealing cover plate, and the output end is extended and fixedly connected to the center of the side of the scraper inner plate. The bottom fixing box is fixedly set at the center of the bottom surface of the main support box. The insertion end of the guide tube is fixedly connected to the output end of the extraction pump body. The fixing screw holes are symmetrically opened on the inner side of the side through groove near both ends.

[0010] In a preferred embodiment of this utility model: the bottom through hole is opened through the center of the bottom surface of the main support box, the two ends of the limiting inner groove extend to the inner side of the side through groove to maintain connection, one end of the support inner frame is fixedly connected to the side of the sealing cover plate, and multiple support inner frames are stacked and arranged in parallel, and the bottom fixing frame is horizontally fixed on the inner side of the support inner frame near the bottom opening end.

[0011] In a preferred embodiment of this utility model: the bottom surface of the support frame is connected to the top surface of the bottom fixing frame, the outer side of the outer snap-fit ​​frame is horizontally snap-fitted to the inner side of the limiting inner groove, and the top end of the connecting top tube is fixedly inserted into the inner side of the bottom through hole to maintain connection.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves horizontally positioning the main support box at a designated point on the EDM machine body, then using bolts to pass through the fixing holes to secure the side strips. During EDM operation, the discharged oil falls downwards into the inner side of the top opening of the main support box, which is designed as an oil receiving basin. After the oil falls into the main support box, it enters the inner support frame. The filter plate at the bottom filters the oil. After multiple layers of filtration, the oil falls to the bottom inner side of the main support box. By activating the extraction pump, the oil is extracted through the connecting top pipe. The oil is drawn into the guide tube, where it can be reused. After a period of time, the output end of the side-mounted cylinder can be controlled to extend and retract, causing the output end to move the scraper plate inside the supporting frame. This scrapes away the residue on the top surface of the filter plate, preventing blockage. Subsequently, the sealing cover can be pulled outward to disassemble, replace, or clean the bottom filter plate. The integrated structure makes installation and use more convenient, and the combination of multiple filtration structures makes oil treatment more thorough and efficient.
