Description

Technical Field

[0001] This utility model relates to the field of electrical discharge machining equipment technology, specifically a low-loss mirror spark forming machine. Background Technology

[0002] Electrical discharge machining (EDM) machines are key equipment for precision mold processing. They remove material through pulsed discharge between electrodes and the workpiece, and are widely used, especially in mirror-grade surface finishing. However, existing equipment suffers from the following technical challenges;

[0003] During the discharge process, the relative posture deviation between the electrode and the workpiece can easily lead to concentrated local discharge, causing excessive wear on the electrode tip. At the same time, the processing area is affected by external airflow interference and working fluid temperature fluctuations, resulting in unstable dielectric constant and uneven discharge energy distribution, further aggravating ineffective electrode erosion, leading to short electrode life, frequent replacement, and increased production costs. Traditional equipment often sprays working fluid in a single direction or at a fixed angle, making it difficult to fully cover the discharge area. Untimely removal of metal debris can easily cause secondary discharge, which not only aggravates electrode wear but also affects the surface finish of the workpiece. The lack of effective environmental isolation measures means that changes in external temperature and airflow disturbances can disrupt the stability of the discharge gap, leading to a decrease in processing accuracy. Moreover, existing feed systems are mostly rigid transmissions, which are difficult to adapt to the dynamic posture compensation requirements of complex curved surface processing. The parallelism deviation between the electrode and the workpiece cannot be corrected in real time, resulting in large fluctuations in the discharge gap during processing, further reducing processing quality and efficiency. In view of this, we propose a low-loss mirror EDM machine to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-loss mirror EDM machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-loss mirror EDM machine, comprising a base, an adjustment mechanism, a telescopic cylinder, a universal adjustment frame, a clamping plate, a working groove, and a water tank. A worktable is fixedly connected to the upper side of the base, and a working groove is provided on the worktable. An installation frame is fixedly connected inside the working groove, and a telescopic cylinder is provided on the installation frame. The output end of the telescopic cylinder is fixedly connected to the universal adjustment frame. An EDM workpiece is placed below the universal adjustment frame, and adjustment mechanisms are symmetrically arranged on both sides of the working groove.

[0006] Preferably, the adjustment mechanism includes an adjustment frame, an adjustment nozzle, a delivery pipe, a water pipe, an adjustment rod, a transmission rod, and a knob. The adjustment rod is symmetrically and movably connected in the working groove, and multiple adjustment frames are arranged at equal distances on both sides of the working groove. The adjustment nozzle is movably connected to the adjustment frame. A water pipe is fixedly connected to the side of the working groove near the adjustment rod. Multiple delivery pipes are arranged at equal distances on one side of the water pipe, and the adjustment nozzle is movably connected to the water pipe through the delivery pipe.

[0007] Preferably, the adjusting rod is provided with multiple transmission rods at equal intervals, and each transmission rod is provided with an adjusting nozzle on the side away from the adjusting rod, and the adjusting rod is fixedly connected to a knob through the worktable.

[0008] Preferably, a water pump is installed inside the water tank, and a cooling pipe is installed on the side of the base near the working tank. The output end of the water pump is fixedly connected to the cooling pipe and the water pipe respectively.

[0009] Preferably, a clamping plate is fixedly connected inside the working groove, and a workpiece is placed inside the clamping plate, with the workpieces cooperating with each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The adjustment mechanism forms a surrounding working fluid spray layout through multiple sets of adjustable nozzles. With the linkage structure of the transmission rod and the adjustment rod, the spray angle of all nozzles can be adjusted synchronously by the knob. The constant temperature inert gas is sprayed to form an airflow barrier, forming an annular airflow barrier on the outer layer of the working fluid. This isolates the external airflow from the interference of the processing area, while reducing the change in dielectric constant of the working fluid due to temperature fluctuations, stabilizing the discharge energy distribution. In addition, the working fluid not only acts as a discharge medium to break down and generate sparks, but also carries away metal debris and local high temperatures generated during processing through high-speed flow, avoiding additional electrode wear caused by secondary discharge of debris.

[0012] 2. The telescopic cylinder, in conjunction with the universal adjustment frame, forms a flexible feeding system that can achieve micro-posture adjustment of the workpiece in three-dimensional space. It can compensate for the parallelism deviation between the electrode and the workpiece in real time, avoiding excessive wear of the electrode tip caused by concentrated partial discharge. It is especially suitable for wear balance control during the machining of complex curved surfaces. The stable mechanical foundation reduces the random fluctuation of the discharge gap, indirectly reducing the ineffective erosion of the electrode caused by sudden gap changes.

[0025] The working principle of this utility model is as follows: When using this device, the adjustment mechanism 2 forms a surrounding working fluid spray layout through multiple sets of adjustment nozzles 202.
