Abstract
The invention discloses a feeding control method for feeding abrasive sand into the multi-line cutter workbench at the lower part of the contact face between steel wire and work-piece. The invention is characterized in that the workbench feeding is changed from continuous feeding into intermittent reciprocal feeding. The invention has simple control, and 20-50% improved cutting efficiency when cuts diamond (HRC65-85) and carbon silicon (HRC75-95), to reduce cost.
Description
Technical field:
The present invention relates to a kind of multi-line cutting machine, specifically a kind of feed control method of multi-wire saw working bench.
Background technology:
At present, utilizing multi-line cutting machine when cutting exceptional hardness material such as jewel (HRC65～85), carborundum (HRC75～95) workpiece, because workpiece material hardness height, abrasive sand enters very difficulty of steel wire and workpiece contact-making surface bottom during cutting, therefore the unit interval stock removal rate is low, influences cutting machine efficient and cut quality.(surpass actual cut-off velocity) too soon as the relative feeding of workbench work in the cutting process simultaneously, in fact workpiece is in and cuts situation by force, it is the extraordinary bending of wire between the multiple-grooved roller, slight swing before and after wire will have with the cutting process, can't remain at operation in the plane, also will have a strong impact on the quality of cut workpiece.External large-scale line cutting machine adopts main shaft to wave usually when this type of material of cutting or workbench waves, and the first is convenient to abrasive sand and is entered, and its two changes cutting junction line contact is the some contact, with lifting cutting machine efficient and cut quality.But have complex structure, inconvenient maintenance, after use a period of time, machining accuracy reduces.
Summary of the invention:
Abrasive sand enters steel wire contacts basifacial multi-wire saw working bench with workpiece feed control method when the purpose of this invention is to provide a kind of convenient cutting.
The present invention adopts following technical scheme to realize its goal of the invention, for imported the abrasive sand of shear action sustainedly and stably in steel wire and cut workpiece contact-making surface bottom, to improve small-sized line cutting machine cutting efficiency and cut quality, the table feed mode is adjusted in redesign, change continuous feed into interrupted reciprocating feed, and depend on accurate location and the motor function that the workbench servomotor is controlled, and uniformity and the repeatability of superior Real Time Control Function to guarantee running precision in the cutting process of Programmable Logic Controller (PLC) efficient stable.
The table feed cycle of the present invention comprises cutting feed section D1, move back platform advances sand section D2.
The present invention is for improving cutting efficiency, and the table feed cycle comprises cutting feed section D1, move back platform advances sand section D2, advances sand and finish and recover a section D3.
The present invention is for improving cutting efficiency and quality, and cutting feed section D1 comprises initial cut feed section D1A, normally cuts feed section D1B.
The displacement of initial cut feed section D1A of the present invention is the 0.1-0.3 of cutting feed section D1 displacement.
The present invention enters steel wire and cut workpiece contact-making surface bottom for ease of abrasive sand, and the 2-15 that moves back displacement that platform advances sand section D2 and be the abrasive sand granularity doubly.
Owing to adopt technique scheme, the present invention has realized goal of the invention preferably, its control method is simple, realize easily, compare with former control mode, during at cuttings such as high hardness material such as jewel (HRC65～85), carborundum (HRC75～95) workpiece, guaranteeing under the cut quality prerequisite, can significantly improve cutting efficiency 20-50%, use relevant cost thereby reduce the user significantly.Through sapphire (HRC:75) and carborundum (HRC:90) are carried out trial cut, under same specification dimension workpiece situation, total clipping time by shortened to 20.5 hours respectively in original 29.5 hours, 45 hours, 25.5 hours, and the cutting quality obviously improves, and reaches the user and expects requirement.
Description of drawings:
Fig. 1 is divided into cutting feed section D1 the table feed cycle of the present invention, moves back time-displacement diagram that platform advances sand section D2;
Fig. 2 is divided into cutting feed section D1 the table feed cycle of the present invention, moves back platform and advance sand section D2, advance sand and finish time-displacement diagram of recovering section D3;
Fig. 3 be divided in the table feed cycle of the present invention initial cut feed section D1A, normally cut feed section D1B, move back platform and advance sand section D2, advance sand and finish time-displacement diagram of recovering section D3.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing.
For imported the abrasive sand of shear action sustainedly and stably in steel wire and cut workpiece contact-making surface bottom, to improve small-sized line cutting machine cutting efficiency and cut quality, the table feed mode is adjusted in redesign, change continuous feed into interrupted reciprocating feed, and depend on accurate location and the motor function that the workbench servomotor is controlled, and uniformity and the repeatability of superior Real Time Control Function to guarantee running precision in the cutting process of Programmable Logic Controller (PLC) efficient stable.
Embodiment 1:
As shown in Figure 1, the table feed cycle comprises cutting feed section D1, moves back platform and advance sand section D2.For guaranteeing that abrasive sand inputs to steel wire and cut workpiece contact-making surface bottom, the 2-15 that moves back displacement that platform advances sand section D2 and be the abrasive sand granularity is (present embodiment is 2 times) doubly.Cut the cycle each time after (wire makes a round trip) finish, workbench descends, and steel wire will have the abrasive sand of certain viscosity and bring joint-cutting into, and workbench rises, and beginning is cut the cycle next time, and so forth.
Embodiment 2:
As shown in Figure 2, be further to improve cutting efficiency, the table feed cycle comprises cutting feed section D1, move back platform advances sand section D2, advances sand and finish and recover a section D3, and the 2-15 that moves back displacement that platform advances sand section D2 and be the abrasive sand granularity is (present embodiment is 10 times) doubly.Surplus with embodiment 1.
Embodiment 3:
As shown in Figure 3, for further improving cutting efficiency and cut quality, the table feed cycle comprises cutting feed section D1, move back platform advances sand section D2, advances sand and finish and recover a section D3, and the 2-15 that moves back displacement that platform advances sand section D2 and be the abrasive sand granularity is (present embodiment is 15 times) doubly.Cutting feed section D1 comprises initial cut feed section D1A, normally cuts feed section D1B, and the displacement of initial cut feed section D1A is for the 0.1-0.3 (present embodiment is 0.2) of cutting feed section D1 displacement, and is surplus with embodiment 1.
