Description

Technical Field

[0001] The invention belongs to the technical field of electrode wire cutting, in particular to a wire cutting processing device for automobile hardware moulds and a use method thereof. Background Art

[0002] The CNC electrode wire cutting machine can be divided into two parts: the machine mainframe and the control cabinet. The control cabinet is equipped with a control system and an automatic programming system, which can perform automatic programming and digital control of the movement of the machine tool coordinate table in the control cabinet. It is used to control the relative movement between the electrode wire and the workpiece. It is composed of the upper and lower slides of the wire storage barrel assembly, a gear pair, a screw pair, a reversing device and an insulating part. During the processing, the surface of the electrode wire is covered with cutting fluid, which is used to provide a working fluid with a certain insulating performance as a working medium, and can also cool the workpiece and the electrode wire;

[0003] During use, the cutting fluid needs to be recycled. After being collected by the coordinate table, it enters the cutting fluid cooling box and is extracted to the machine tool for use again. During the cutting process, cutting chips will be generated. The dirtiness of the upper and lower nozzles needs to be checked regularly. If there is dirt, cleaning fluid is needed to remove it. If there are too many impurities in the cutting fluid, the cutting fluid needs to be replaced, otherwise the cutting fluid loses its insulating effect. Among the impurities generated, there will be iron-containing debris. The filter cotton in the cutting fluid cooling box needs to be filtered manually, and the iron-containing debris cannot be accurately filtered out. If the debris is not collected in time, it will also cause the filter cotton to be blocked.

[0015] A method for using a wire cutting processing device for automobile hardware molds, comprising:

[0016] Step 1: The workpiece is mounted on the coordinate workbench and cut using a wire rack;

[0017] Step 2: The coordinate worktable moves on the cutting machine body to cut the workpiece into different shapes. The cutting fluid passes through the liquid inlet pipe and covers the surface of the molybdenum wire used for cutting. The cutting fluid flows to the surface of the coordinate worktable, and then after being collected by the coordinate worktable, it flows into the cutting fluid cooling box through the liquid outlet pipe.

[0018] Step 3: When the cutting liquid is collected, it will be mixed with impurities in the cutting process and flow into the primary filter box through the liquid outlet pipe.

After being pumped out by the water pump, the liquid inlet pipe is discharged into the main body of the cutting machine tool, and the cutting fluid circulates again.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention realizes the circulation of cutting liquid by utilizing a liquid inlet pipe and a liquid outlet pipe. By arranging a primary filter box on the outside of the cutting liquid cooling box, the incoming cutting liquid can be initially filtered to clean up large particles of impurities, which is convenient for the next step of filtration. By arranging a rotating filter cylinder, filtering is no longer performed on the same place during filtration, and the rotating filter cylinder can also facilitate the cleaning of impurities on the inner wall of the cylinder. During the filtration process, impurities on the inner wall of the cylinder can be processed in real time without affecting the normal use of the cutting liquid. Then, the impurities that have not been filtered are adsorbed by magnetic adsorption of electromagnets, and after sedimentation and filtration, they are discharged into the liquid storage tank to ensure the filtration accuracy of the cutting liquid.

[0024] 2. The present invention uses multi-stage filtration to filter different types of impurities, which has targeted filtration. The setting of graded filtration can also reduce the burden of filtration, making the filtration more targeted. BRIEF DESCRIPTION OF THE DRAWINGS
