Description
Technical field
The utility model discloses a kind of electric discharge machining apparatus, be specifically related to a kind of aperture machine edm control device.
Background technology
The aperture machine is through utilizing the fine wire (being called wire electrode) that moves continuously to make electrode, workpiece being carried out pulse spark discharge ablation metal, excision forming.Different with electric spark linear cutting machine, make-up machine is that the electrode of its electric pulse is a hollow copper bar.Medium passes with workpiece from the copper rod hole and discharges, and corroding metal reaches the purpose of perforation, but is used to process the pore of superhard steel, carbide alloy, copper, aluminium and any conductive material.
Traditional aperture machine edm mode is mainly manual input and sets working depth, and because the aperture machine does not have the function of automatic rollback, after the machining hole degree of depth puts in place; Machined electrode is stayed in the machining hole position; Need manually it to be shifted out, operation is trouble comparatively, and the repeatedly setting working depth is all wanted in each processing; Cause the increase of the amount of labour, operating efficiency reduces.And the bigger error of traditional manual operation existence, cause the machining hole precision low, defect rate promotes, and production cost increases accordingly.
For addressing the above problem, a kind of the processing amount of feeding and rollback amount can be set automatically, improve machining accuracy, reduce workload, to increase work efficiency, the Working control device that reduces production costs is demanded appearance urgently.
The utility model content
Need manual set depth for solving traditional aperture machine edm mode; There is not the rollback function, causes that the amount of labour is big, operating efficiency is lower, mismachining tolerance is big, production cost is than problems such as height, the utility model discloses a kind of aperture machine edm control device; To reach the raising machining accuracy; Reduce workload, increase work efficiency the purpose that reduces production costs.
For achieving the above object, the technical scheme of the utility model is following:
A kind of aperture machine edm control device comprises working portion and automatically controlled part, and said working portion comprises that the discharge that machined electrode is set is anodal, with the discharge negative pole that workpiece to be processed is set; Said electric control part branch comprises and the anodal voltage comparator that is connected with said discharge negative electricity of said discharge, and the relay that is electrically connected with said voltage comparator; Said automatically controlled part also comprises the monitoring device that is used to set feeding and rollback amount, is electrically connected with the contact-making switch corresponding with said relay on the said monitoring device.
Preferably, said monitoring device is a digital display device.
The disclosed aperture machine of the utility model edm control device, through the discharge voltage of voltage comparator testing end, thus the adhesive of control relay and contact-making switch; Confirm the position at workpiece place, can the amount of feeding and rollback amount all be inputed in the monitoring device simultaneously, according to the amount of the setting processing and the rollback of control hole voluntarily; Improve the machining accuracy of workpiece; Reduce production cost, reduced the amount of labour simultaneously, improved operating efficiency.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the disclosed a kind of aperture machine edm control device of the utility model.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of aperture machine edm control device,, reduce workload, increase work efficiency the purpose that reduces production costs to reach the raising machining accuracy.
As shown in Figure 1, a kind of aperture machine edm control device comprises working portion and automatically controlled part, and working portion comprises that the discharge that machined electrode is set is anodal, with the discharge negative pole that workpiece to be processed is set; Through electrode discharge to the workpiece processing of boring a hole.
The electric control part branch comprises and the anodal voltage comparator that is connected with the discharge negative electricity of discharge, and the KA relay that is electrically connected with voltage comparator; Voltage comparator is general sets a magnitude of voltage, compares the work operation follow-up according to the voltage condition control of discharge working end with the voltage of discharge working end.
Automatically controlled part also comprises the monitoring device that is used to set feeding and rollback amount, is electrically connected with the KA contact-making switch corresponding with the KA relay on the monitoring device.This monitoring device is a digital display device.Before the processing, need working depth and the rollback amount all input in the digital display device, through the carrying out of digital display device control processing.
The operation principle of the utility model is following:
At first voltage comparator is set certain magnitude of voltage; Be generally 60V; The voltage that detects the edm end when voltage comparator is during less than 60V, and the adhesive of KA relay control KA contact-making switch is when the digital display device zero clearing; Explain that sparking electrode arrives surface of the work, the digital display device control electrode is processed workpiece.
The disclosed aperture machine of the utility model edm control device, through the discharge voltage of voltage comparator testing end, thus the adhesive of control relay and contact-making switch; Confirm the position at workpiece place, can the amount of feeding and rollback amount all be inputed in the monitoring device simultaneously, according to the amount of the setting processing and the rollback of control hole voluntarily; Improve the machining accuracy of workpiece; Reduce production cost, reduced the amount of labour simultaneously, improved operating efficiency.
And digital display device is the required parameter of switch discharges process voluntarily, and switch, the pulse power, high-pressure hydraulic pump, main shaft rise are all omitted with manually-operated processes such as main shaft put in place, effectively reduces workload.
More than be description,, make this area professional and technical personnel can realize or use the utility model through above-mentioned explanation to the disclosed embodiments to the utility model embodiment.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
