Description

Technical Field

[0001] The invention relates to the technical field of bullhead spark machines, in particular to a bullhead spark machine and a method for circulating cooling of a mold. Background Art

[0002] Spark machine is a kind of mechanical processing equipment, mainly used for EDM machining, widely used in the manufacture of various metal molds and mechanical equipment. The Bullhead spark machine realizes automatic control through computer to complete complex and precise spark machining.

[0003] The authorized patent number CN218694657U discloses a bullhead spark machine for processing mold cavity molds. The device mainly arranges a workbench above a fixed plate, and arranges racks and gears below the workbench. Under the rotation of a rotating rod, the rotating rod realizes the lifting and lowering of the workbench through the gear. Through such a setting, the height of the workbench above the fixed plate can be flexibly adjusted, which is convenient for the workbench to drive the mold cavity mold to move accurately, realizes accurate processing of the mold cavity mold, and ensures the processing quality of the mold cavity mold. However, when the device is actually used, the following defects still exist;

[0004] The above patent mainly moves the mold cavity mold accurately by lifting the workbench, and removes the metal chips by spraying liquid. However, when the spark machine is actually working, the processed mold may be displaced and misaligned due to the impact of the water spray, and as the volume and shape of the mold are different, a single coolant spraying system cannot spray the mold comprehensively, resulting in excessively high local temperature of the mold, and it is difficult to fully flush the metal chips, affecting the processing accuracy of the spark machine. At the same time, the coolant and metal chips are easily concentrated together and difficult to separate, causing the device to be unable to fully meet the cooling work of the mold. In addition, smoke is easily generated during spark machine processing, and the metal chips of the mold may float around, affecting the working environment of the processing table.

[0046] A processing method of a bullhead spark machine for mold circulation cooling, the processing steps are as follows:

[0047] Step 1: Place the processed mold on the workbench surface, and then use the data control of the Bullhead spark machine to allow the electrode device to process the mold surface;

[0048] Step 2: Set a protective cover on the outside of the mold processing, and set up a dust suction structure and a working fluid spray cooling structure inside the protective cover, so that when the spark machine is working, the smoke generated by the spark machine is absorbed and processed according to the smoke concentration requirements, and the coolant spray structure is used to cool the mold according to the cooling requirements of the mold;

[0049] Step three: receiving and filtering the metal particles from the cooling working fluid, recycling the cooling fluid, and circulating cooling the mold in the processing state;

[0050] Step 4: Actively shake the workbench and the filter structure to promote the filtration of the working fluid and the discharge of the working fluid and metal scraps on the workbench surface, thereby accelerating the circulation, filtration and cooling quality of the liquid.

[0051] Embodiment 1, as Figure 1-3 and Figure 6 As shown, before the circular protective frame 51 is raised or lowered, the two sets of adjusting motors 57 can be started, and the threaded rod 513 can be driven to rotate by independent control of the two sets of adjusting motors 57, and the moving block 512 and the positioning plate 52 can be driven to move, so as to be adjusted according to the width of the mold. After adjusting to the specified position, the positioning plate 52 is driven to contact and extrude the mold by lowering the circular protective frame 51, so that the circular protective frame 51 can wrap and protect the workbench 61 while allowing the positioning structure on the inside of the circular protective frame 51 to actively contact the mold to position the mold, thereby avoiding the mold from shifting and misaligning under spark machining and cooling by coolant, thereby increasing the machining accuracy of the mold.

[0052] Embodiment 2, as Figure 1-3 and Figure 6 As shown, after the circular protective frame 51 is raised and lowered, the two sets of adjusting motors 57 can be started and the threaded rod 513 can be driven to rotate by independent control of the two sets of adjusting motors 57, and the moving block 512 and the positioning plate 52 can be driven to move so as to adjust according to the width of the mold, and the two sets of positioning plates 52 can be prompted to actively fit and clamp the offset side walls of different shapes to position the mold, thereby avoiding the mold from being offset and misaligned during spark machining and cooling by coolant, and increasing the processing accuracy of the mold.

[0053] Working principle: This is used in the bullhead spark machine for mold circulation cooling;

[0054] First, the mold to be processed is placed on the surface of the workbench 61, and then the servo motor 43 is started to drive the screw rod 44 to rotate, so that the lifting block 46 drives a group of guide blocks 41 to be lifted and lowered under the limit cooperation of the guide rail 42 under the rotation of the screw rod 44, so that the overall structure of the return-shaped protection frame 51 drives another group of guide blocks 41 and the guide rail 42 to be lifted and lowered synchronously, so that the return-shaped protection frame 51 is lowered as a whole, and a protection structure is formed around the workbench 61. At this time, the data control of the displacement adjustment mechanism 3 can be used to automatically process the mold, and during the process, A smoke sensor is arranged in the return-shaped protection frame 51, so that the smoke generated by the spark machine can be actively absorbed by the dust hood 54 when the suction fan 55 is started, and the working coolant in the liquid storage tank 7 is actively extracted by starting the circulation pump 510, so that two groups of cooling channels are formed under the diversion effect of the infusion pipe 59, the telescopic hose and the diversion pipe 58, and the workbench 61 and the mold inside the return-shaped protection frame 51 are discharged from the drainage hole 53 to cool the mold, so as to quickly wash the mold and metal chips and improve the processing quality of the spark machine;

[0055] When the flushing working fluid and metal chips seep from the workbench 61 together, the working fluid and the metal chips can be separated and filtered through the two sets of filter screens 610 inside the machine body 1, so that the working fluid can flow into the liquid storage tank 7 again, so that the working fluid can be circulated and cooled for use, thereby maintaining the accuracy of the working fluid and saving processing costs. After the mold is processed, the start of the dual-axis motor 611 is used to synchronously drive the incomplete gear 64 and the cam 67 to rotate. As the incomplete gear 64 rotates and meshes with the inner gear ring 63, the inner gear ring 63 drives the working The table 61 as a whole is moved back and forth under the sliding cooperation of the moving seat 62 and the two sets of sliders 613 and the slide groove 612, so that the working fluid and metal chips remaining on the surface of the workbench 61 are actively discharged, and the rotation of the cam 67 can intermittently drive the sliding bracket 69 and the two sets of filter screens 610 to move left and right under the elastic cooperation of the spring 68, thereby promoting the filtering effect of the working fluid and metal chips on the surface of the filter screen 610, further improving the recycling accuracy and quality of the coolant, and finally lifting the return protection frame 51 as a whole again to take out the processed mold.

Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
