Description
Technical Field
The invention discloses a cross group groove coding type flow field electrolytic machining method and device, and belongs to the technical field of electrolytic machining.
Background
The micro-scale array group groove structure is applied to compact and integral heat and mass transfer application devices such as fuel cells, fuel processors and the like more and more widely. In order to meet the use requirements of high temperature resistance, corrosion resistance, good electric conduction and heat conduction characteristics, the structure generally adopts titanium alloy, high-temperature alloy, stainless steel and other difficult-to-process materials, and is distributed on a large-scale metal sheet, so that new challenges are brought to the existing manufacturing technology.
The electrochemical anode dissolution is controlled to remove the workpiece material by the electrochemical machining technology, the machining process is not limited by mechanical properties such as the strength and hardness of a metal material, no tool loss exists, the surface quality of the workpiece is good, and machining defects such as residual stress, metal burrs and recast layers do not exist. When an electrochemical machining technique is used to machine the cross cluster tool structure, the tool cathode is typically an array of protrusions that mimic the cluster tool structure to be machined. In the processing process, the cathode is connected with the negative pole of a power supply, the metal trough plate is connected with the positive pole of the power supply, high-speed and high-voltage electrolyte flows through the middle of the cathode and the anode, and the efficient processing and forming of the array group trough structure can be realized only by feeding once. Therefore, the electrolytic machining technology is particularly suitable for machining and forming the array group groove structure of the metal thin-wall material which is difficult to machine.
In electrolytic processing, the electrolyte between the cathode and anode is the carrier for electrochemical dissolution of the anode. During processing, the conductivity of the electrolyte in the processing zone is not uniformly distributed but changes nonlinearly along the flow path under the influence of hydrogen generated on the cathode surface, insoluble products generated by anode dissolution, joule heat in the circuit and the like. The uneven distribution of the conductivity of the electrolyte can cause the uneven dissolution of the anode in the processing area, and influence the processing precision of the workpiece; in severe cases, short-circuiting between the anode and the cathode, and severe damage to the anode and the processing system may occur. Therefore, the electrolytic product is discharged in time and quickly, and the effective updating of the electrolyte in the processing area is realized, so that the consistency of the conductivity of the electrolyte in the processing area is improved, and the method is the key for ensuring the normal operation of electrolytic processing and improving the electrolytic processing precision.
Aiming at the processing of an array micro-channel structure, the patent of the triarrhena, the liujia and the aachen, namely' group groove electrolytic processing tool with a telescopic comb-shaped liquid sealing structure and a method thereof, discloses a group groove electrolytic processing tool with a telescopic comb-shaped liquid sealing structure, wherein the tool can effectively inhibit the stray corrosion of the upper surface of ribs between array channels, and can obviously improve the forming quality of the processing of an array straight groove. However, when the cross group groove is processed, the electrolyte flowing in one direction will tend to impact the side wall of the tool cathode perpendicular to the flow direction, so that the flow resistance of the electrolyte is greatly increased. If the electrolyte cannot bring the product out of the machining gap, machining accidents such as short-circuiting may be induced. The article, "metal array structure template electrolytic machining key technology research", by the King provides a template electrolytic machining array group groove machining method, which controls the dimension and contour precision of the group groove structure to be machined by controlling the machining time of the template electrolytic machining, and realizes the high-efficiency machining of the array group groove structure. "a micro-channel electrolytic processing device, ZL 201810467763.5" of patent of cheng zhi et al proposes a novel jet electrolytic processing method, which integrates an electrolyte spray head, an insulating template and an electrolyte through hole, and solves the problems of low efficiency and poor product precision of the traditional jet electrolytic processing. Both etching and jet flow can realize electrolytic machining of crossed grooves, but both are free to corrode, the shape and contour accuracy consistency of the grooves is difficult to control, and the grooves with rectangular sections cannot be machined. Therefore, an effective method for electrolytic machining with cross group bath is urgently needed.
Disclosure of Invention
The invention aims to solve the problem of electrolyte updating in the electrolytic machining of a cross group groove structure, and provides a cross group groove coding type flow field electrolytic machining method and device with simple structure and strong practicability.
A crossing group groove coding type flow field electrolytic machining method is characterized in that a crossing group groove workpiece is formed by mutually and vertically crossing N transverse grooves and K longitudinal grooves, and a rib structure between crossing group grooves is called as a separating rib; the method is characterized in that:
the tool cathode is an array convex structure corresponding to a cross group groove structure to be processed, the array convex structure is formed by mutually and vertically arranging N transverse tables and K longitudinal tables in a cross mode, and the height of the convex structure is larger than the target depth of the cross group groove to be processed;
gaps among the array convex structures of the tool cathode are used as blank grooves distributed in an (N-1) × (K-1) array for accommodating corresponding array partition ribs among the crossed group groove structures;
the cutter grooves are communicated up and down, and electrolyte enters and exits from the cutter grooves; marking the liquid inlet empty knife groove as 1 and the liquid outlet empty knife groove as 0, and arranging the liquid inlet and outlet empty knife grooves into a liquid inlet and outlet coding matrix of (N-1) × (K-1);
the liquid inlet and outlet coding arrangement rule of the tool cathode clearance groove is as follows: firstly, setting a clearance groove at one corner of a tool cathode as a liquid inlet clearance groove, wherein the code is 1, and taking the clearance groove as a reference, arranging the clearance grooves according to the alternating arrangement rule of the liquid inlet clearance groove and the liquid outlet clearance groove, so that the periphery of each liquid inlet clearance groove on the tool cathode of the cross group groove is a liquid outlet clearance groove, and the periphery of each liquid outlet clearance groove is a liquid inlet clearance groove; in addition, in order to ensure the processing stability of the corners, it is required to ensure that the clearance grooves at all the corners of the crossed group grooves are liquid inlet clearance grooves;
therefore, during processing, electrolyte flows in from the liquid inlet clearance grooves, flows to the liquid outlet clearance grooves along the width direction of the groove to be processed in the gap between the cathode and the anode of the processing area, and flows out of the processing area from the adjacent liquid outlet clearance grooves, thereby forming the coding type flow field processing of the crossed group groove.
A device of a cross group groove coding type flow field electrolytic machining method is characterized in that: the device comprises a liquid supply inlet seat, an electrolyte coding distribution interface board, an electrolyte coding liquid supply and liquid outlet partition board and a cross groove tool cathode which are sequentially connected;
the first end of the liquid supply inlet seat is connected with a machine tool movement main shaft, and the second end of the liquid supply inlet seat is connected with the first end of the electrolyte encoding and distributing interface board; the interior of the electrolyte tank is of a hollow structure, and an electrolyte supply interface is arranged on the side surface of the electrolyte tank;
the electrolyte coding distribution interface board is provided with a plurality of vertically-through electrolyte distribution interfaces, and the second end of the electrolyte coding distribution interface board is connected with the first end of the electrolyte coding liquid supply and liquid outlet partition board;
the second end of the electrolyte encoding liquid supply and liquid outlet partition plate is connected with the cathode of the cross groove tool;
according to the code 1 of the liquid inlet and outlet coding matrix, a plurality of electrolyte distribution interfaces which penetrate through an electrolyte coding distribution interface board and an electrolyte supply interface of a liquid inlet clearance groove of a cross groove tool cathode are arranged on an electrolyte coding liquid supply and liquid outlet partition plate;
according to the code 0 of the liquid inlet and outlet coding matrix, a plurality of electrolyte liquid return interfaces communicated with liquid outlet clearance grooves of the cathode of the cross groove tool are arranged on the electrolyte coding liquid supply and liquid outlet partition plate; and an electrolyte outlet communicated with the electrolyte return interface is also arranged on the electrolyte encoding liquid supply and liquid outlet partition plate.
The device utilizing the cross group groove coding type flow field electrolytic machining method comprises the following specific implementation processes:
in the electrolytic machining process, the liquid supply inlet seat is arranged on a moving shaft of the electrolytic machining machine tool, and an electrolyte supply interface on the liquid supply inlet seat is connected with an electrolyte circulating system so as to realize the movement and the electrolyte supply of the cross group groove coding type flow field electrolytic machining device body;
during processing, a workpiece to be processed with a cross groove is connected with the positive electrode of a power supply, and the cathode of a tool with the cross groove is connected with the negative electrode of the power supply;
electrolyte flows into the liquid supply inlet seat from the electrolyte circulating system, flows to the electrolyte coding distribution interface board through a cavity in the liquid supply inlet seat, flows to the electrolyte coding liquid supply and liquid outlet partition board through an electrolyte distribution interface on the electrolyte coding distribution interface board, flows to the liquid inlet clearance groove on the cathode of the cross groove tool through the electrolyte coding liquid supply interface on the electrolyte coding liquid supply and liquid outlet partition board, and finally flows to a processing area of the cross groove;
in the cross tank processing area, the electrolyte flows in the gap between the cathode and the anode along the width direction of the tank to be processed, so that the discharge of electrolytic products in the processing area and the update of the electrolyte are completed; then, the electrolyte flows out of the processing area from the adjacent liquid outlet empty cutter grooves, so that the coding type flow field electrolytic processing of the crossed group of grooves is formed;
after the electrolyte flows out of the processing area, the electrolyte flows back to an electrolyte outlet on the electrolyte encoding liquid supply and liquid outlet partition plate from an electrolyte return interface on the electrolyte encoding liquid supply and liquid outlet partition plate, finally flows out of the encoding type flow field electrolytic processing device body of the cross group groove, and flows back to an electrolyte circulating system.
The invention provides an encoding type flow field electrolytic machining method and device for a cross group groove, aiming at the problems that the traditional lateral flow type electrolytic machining flow field cannot meet the requirements of full discharge of electrolytic products and effective update of electrolyte when a cross group groove structure is machined. The method and the device can disperse the global flow field of the traditional electrolytic processing into a plurality of independent local flow fields, and in each local flow field processing area, the electrolyte is always flushed along the width direction of the tank. The electrolyte flow in the processing area is obviously shortened, the problems of electrolyte flow field disorder, local liquid shortage, overlong flow and the like caused by the existence of a groove structure which is vertically distributed in the electrolyte side flow direction when the traditional side flow type flow field is used for processing the crossed group groove are solved, the timely discharge of the electrolysis products in the processing area and the effective update of the electrolyte can be realized, and the precise and efficient electrolytic processing of the crossed group groove structure is ensured;
the flow length of the electrolyte is always the groove width size of the groove to be processed and is irrelevant to the depth size of the groove to be processed. Therefore, the problem of the attenuation of the flow velocity of the electrolyte caused by the overlong flow path of the electrolyte when the lateral flow type flow field of the traditional electrolytic machining is used for machining a group groove structure with large depth and large depth-to-width ratio is solved. The electrolytic machining of the group groove structure with large depth and large depth-to-width ratio which cannot be realized by the traditional electrolytic machining flow field can be realized;
the cross group groove coding type flow field electrolytic machining device can be directly used only by replacing the cathode of a cross groove tool when machining different groove widths, variable groove widths and even nonlinear cross group groove structures, and is convenient to operate and high in applicability.
The device for realizing the cross group groove coding type flow field electrolytic machining method is characterized in that: the protruding structure of the cathode of the cross groove tool is of a uniform cross section, a linear structure, a variable cross section and a curve structure.
When a group groove structure is machined in the conventional side-flow type electrolytic machining, due to the limitation of a flow field, the electrolyte in a machining area is difficult to update when a group groove with a variable cross section and a curved structure is machined. The method and the device for electrochemical machining of the encoded flow field of the crossed group of the grooves have the advantages that the electrolyte in the machining area is dispersed into a plurality of independent machining areas, and in each machining area, the electrolyte flows into the machining area from the liquid inlet clearance grooves and flows out from the adjacent liquid outlet clearance grooves along the groove width direction, so that the electrolyte updating capacity is not greatly influenced by the cathode structure, and the method and the device are suitable for electrochemical machining of more diversified tool cathode structures.
The cross group groove coding type flow field electrolytic machining method is characterized in that: the method is suitable for pulse vibration coupling electrolytic machining or electrolytic machining in a conventional motion mode.
The pulse vibration coupling electrolytic machining is electrified and machined in a small gap and is washed out in a large gap in a power-off mode, so that the effective updating of electrolyte in a machining area can be realized to a great extent, the electrolytic machining capability of the small gap is improved, and the machining stability and the machining precision of the electrolytic machining are improved; the conventional motion form electrolytic machining, namely only relative feeding motion and no relative vibration motion between a tool cathode and a workpiece anode, has the advantage that the machining stability is more dependent on the effective renewing capacity of electrolyte in a machining area. The method and the device for the electrolytic machining of the cross group groove coding type flow field can greatly improve the effective updating capacity of the electrolyte in the machining area, so the method and the device are suitable for pulse vibration coupling electrolytic machining and are also suitable for electrolytic machining in a conventional motion mode.

In the processing process, the electrolyte flows in from the liquid inlet empty knife groove, flows along the width direction of the groove to be processed in the gap between the cathode and the anode of the processing area and flows out of the processing area from the adjacent liquid outlet empty knife groove, thereby forming the coding type flow field processing of the crossed group groove.
