Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled medium-speed wire cutting equipment, and in particular to a numerically controlled medium-speed wire workpiece cutting equipment. Background Art

[0002] What is medium-speed wire cutting? Medium-speed wire EDM wire cutting belongs to the category of reciprocating high-speed wire cutting EDM wire cutting machine tools. It realizes multiple cutting functions on high-speed reciprocating wire cutting EDM wire cutting machine tools, and is commonly known as "medium-speed wire cutting". Medium-speed wire cutting technology points out here that the so-called "medium-speed wire cutting" does not mean that the wire speed is between high speed and low speed, but a compound wire cutting machine tool, that is, the wire cutting principle is to use high-speed (8-12m / s) wire cutting during rough processing and low-speed (1-3m / s) wire cutting during fine processing. In this way, the work is relatively stable and the jitter is small. Multiple cutting can reduce the error caused by material deformation and molybdenum wire loss, so that the processing quality is relatively improved, and the processing quality can be between high-speed wire cutting machine and low-speed wire cutting machine.

[0003] It should be noted that cutting fluid is indispensable during the processing of cutting machines. However, during processing, the cutting machine may be short of cutting fluid due to poor sealing, overload of the cutting fluid system, aging of the hose, insufficient cross-sectional area or lack of maintenance, which will lead to a decline in processing quality, low processing efficiency and even equipment damage, thus causing huge safety hazards. In addition, during cutting, since the protective box can only block the surroundings, the cutting fluid splashed by cutting is easy to splash everywhere, causing pollution to the machine tool and the environment, and due to the poor environment of the processing workshop, impurities in the workshop are also easy to adhere to the workpiece, and wire cutting cannot remove objects other than metal materials, thus affecting the cutting quality of the workpiece.

[0029] The beneficial effects of a CNC medium-wire workpiece cutting device proposed by the present invention are:

[0030] In the present invention, through the setting of the cutting fluid replenishing mechanism, when the machine tool bed is being processed, the cutting fluid enters the transfer box through the infusion pipe, then enters the transfer pipe through the transfer box, and then is input into the lifting seat through the transfer pipe, and finally is sprayed on the workpiece. At this time, the cutting fluid in the transfer box is full and drives the floating plate to move up. The floating plate moves up and drives the moving frame to move through the lifting float rod. The moving frame slides on the mounting bar and drives the return spring to be stressed. Then the valve is opened so that the outlet pipe can transport the cutting fluid in the liquid storage tank to the transfer box. During the continuous processing, if the cutting fluid is reduced due to accident, the cutting fluid level in the transfer box drops. Under the rebound force of the return spring, the moving frame drives the lifting float rod to move down, and the lifting float rod drives the floating plate to move down, so that the cutting fluid in the liquid storage tank can be replenished into the transfer box in time, and the floating plate can close the infusion pipe to ensure the continuous supply of cutting fluid, thereby ensuring the processing quality of the workpiece.

[0031] Furthermore, in the present invention, by setting up a blocking protection mechanism and adding two blocking covers on the protection box, it is possible to effectively prevent the workpiece from splashing out of the protection box during the cutting process, thereby causing pollution to the machine tool or the environment. At the same time, when the processing table moves, the blocking cover is squeezed by the lifting seat or the wire feeding frame, and the blocking cover slides in the pushing groove through the pushing block, and drives the return spring to be stressed. When the processing table is reset, the blocking cover can be reset under the rebound force of the return spring, thereby effectively ensuring the blocking effect of the blocking cover.

[0032] Furthermore, in the present invention, through the setting of the interlocking locking mechanism, when the infusion tube transports cutting fluid, the infusion tube is forced to sink, thereby driving the lower pull bar to move downward, and the lower pull bar moves vertically in the positioning bar through the lower pull block, and drives the lower pull spring to be stressed. At the same time, the downward movement of the lower pull bar drives the locking frame to move, and the locking frame moves in the connecting hole and is inserted in the locking groove to move, thereby locking the protective box on the processing table, effectively avoiding the problem of the protective box being accidentally opened during processing, and ensuring the normal progress of the processing work.

[0051] It also includes a cutting fluid replenishing mechanism 6, which is installed on the lifting seat 3, and the infusion tube 5 is connected to the cutting fluid replenishing mechanism 6, and the cutting fluid replenishing mechanism 6 is used to replenish the cutting fluid for the infusion tube 5; specifically, the cutting fluid replenishing mechanism 6 includes a transfer box 601, the transfer box 601 is installed on the lifting seat 3, the infusion tube 5 is connected to the bottom side of the transfer box 601, and the top side of the transfer box 601 is connected to a transfer tube 602, and the transfer tube 602 is connected to the lifting seat 3, and a liquid storage tank 603 is installed on the top side of the lifting seat 3, and a liquid outlet tube 604 is connected between the liquid storage tank 603 and the transfer box 601.

[0052] It should be noted that, in the embodiment of the present invention, by setting the cutting fluid replenishing mechanism 6, when the machine tool bed 1 is processed, the cutting fluid enters the adapter box 601 through the infusion tube 5, then enters the adapter tube 602 through the adapter box 601, and then is input into the lifting seat 3 through the adapter tube 602, and finally sprayed on the workpiece. At this time, the cutting fluid in the adapter box 601 is full, and drives the floating plate 605 to move upward. The floating plate 605 moves upward and drives the moving frame 608 to move through the lifting float rod 606. The moving frame 608 slides on the mounting bar 607 and drives the return spring 609 to be stressed, and then the valve is opened. Door 612 allows the liquid outlet pipe 604 to transport the cutting fluid in the liquid storage tank 603 to the transfer box 601; in addition, during the continuous processing, if the cutting fluid is accidentally reduced, the cutting fluid level in the transfer box 601 will drop, and under the rebound force of the return spring 609, the movable frame 608 drives the lifting float rod 606 to move downward, and the lifting float rod 606 drives the floating plate 605 to move downward, so that the cutting fluid in the liquid storage tank 603 can be replenished into the transfer box 601 in time, and the floating plate 605 can close the infusion pipe 5 to ensure the continuous supply of cutting fluid, thereby ensuring the processing quality of the workpiece.

Then, when the processing table 2 is reset, the rebound force of the pull-back spring 705 allows the blocking cover 701 to be reset, thereby effectively ensuring the blocking effect of the blocking cover 701.

[0056] In addition, it is also necessary to explain that, through the setting of the interlocking locking mechanism 8, when the infusion tube 5 transports cutting fluid, the infusion tube 5 is forced to sink, thereby driving the pull-down bar 801 to move downward, and the pull-down bar 801 moves vertically in the positioning bar 805 through the pull-down block 806, and drives the pull-down spring 807 to be stressed. At the same time, the downward movement of the pull-down bar 801 drives the locking frame 802 to move, and the locking frame 802 moves in the connecting hole 803 and is inserted in the locking groove 804 to move, thereby locking the protective box 9 on the processing table 2, effectively avoiding the problem of the protective box 9 being accidentally opened during processing, and ensuring the normal progress of the processing work.

At this time, the cutting fluid in the adapter box 601 is full, and drives the floating plate 605 to move upward. The floating plate 605 moves upward and drives the moving frame 608 to move through the lifting float rod 606. The moving frame 608 slides on the mounting bar 607 and drives the return spring 609 to be stressed, and then the valve 612 is opened, so that the outlet pipe 604 can transport the cutting fluid in the liquid storage tank 603 to the adapter box 601.

[0067] Please continue to refer to the instruction manual Figure 3 and Figure 9-10 Specifically, in the embodiment of the present invention, a connecting hole 803 is provided on the inner wall of the protection box 9, and the locking frame 802 passes through the connecting hole 803; in addition, a locking groove 804 is provided on the top side of the processing table 2, and the bottom side of the locking frame 802 is inserted into the locking groove 804. It should be noted that in the embodiment of the present invention, when the lower pull bar 801 is forced to move downward, the locking frame 802 is synchronously driven to move, and the locking frame 802 moves in the connecting hole 803 and is inserted in the locking groove 804 to move, thereby locking the protection box 9 on the processing table 2, effectively avoiding the problem of the protection box 9 being accidentally opened during processing, and ensuring the normal processing work.

[0068] In summary, the working principle of a CNC wire workpiece cutting device provided by an embodiment of the present invention is:

[0069] When the machine tool bed 1 is being processed, the cutting fluid enters the transfer box 601 through the infusion tube 5, then enters the transfer tube 602 through the transfer box 601, and then is input into the lifting seat 3 through the transfer tube 602, and finally sprayed on the workpiece. At this time, the cutting fluid in the transfer box 601 is full, and drives the floating plate 605 to move upward. The floating plate 605 moves upward and drives the moving frame 608 to move through the lifting float rod 606. The moving frame 608 slides on the mounting bar 607 and drives the return spring 609 to be stressed, and then the valve 612 is opened, so that the liquid outlet pipe 604 can be The cutting fluid in the liquid storage tank 603 is transported to the transfer box 601; during the continuous processing, if the cutting fluid is reduced due to an accident, the cutting fluid level in the transfer box 601 drops, and under the resilience of the return spring 609, the movable frame 608 drives the lifting float rod 606 to move downward, and the lifting float rod 606 drives the floating plate 605 to move downward, so that the cutting fluid in the liquid storage tank 603 can be replenished into the transfer box 601 in time, and the floating plate 605 can close the infusion pipe 5 to ensure the continuous supply of cutting fluid, thereby ensuring the processing quality of the workpiece;

[0070] Furthermore, by adding two blocking covers 701 to the protective box 9, it is possible to effectively prevent the workpiece from splashing out of the protective box 9 during the cutting process, thereby causing pollution to the machine tool or the environment. At the same time, when the processing table 2 moves, the blocking cover 701 is squeezed by the lifting seat 3 or the wire feed frame 4, and the blocking cover 701 slides in the pushing groove 703 through the pushing block 704, and drives the return spring 705 to be stressed. When the processing table 2 is reset, the blocking cover 701 can be reset under the rebound force of the return spring 705, thereby effectively ensuring the blocking effect of the blocking cover 701; in addition, when the two blocking covers 701 are opened, the handle 714 is pulled to disengage the driving rod 709 from the slot. 713, and then drives the handle 714 to move downward, so that the handle 714 drives the push-pull bar 710 to move through the driving rod 709, and the push-pull bar 710 drives the two unfolding frames 706 to rotate and unfold through the two push-pull shafts 711, and at the same time the push-pull shaft 711 slides in the unfolding slot 715, the unfolding frame 706 rotates through a support shaft 707 to rotate in the rotating slot 716, and drives the torsion spring 717 to be stressed, and at the same time the unfolding frame 706 rotates through another push-pull shaft 711 to drive the protective box 9 to slide open, the protective box 9 slides in the two sliding slots 718 through the two sliding bars 719, and the push-pull shaft 711 slides in the driving slot 708, so as to realize the convenient and rapid unfolding of the two protective boxes 9;

[0071] Furthermore, when the infusion tube 5 transports cutting fluid, the infusion tube 5 is forced to sink, thereby driving the pull-down bar 801 to move downward. The pull-down bar 801 moves vertically in the positioning bar 805 through the pull-down block 806, and drives the pull-down spring 807 to be stressed. At the same time, the downward movement of the pull-down bar 801 drives the locking frame 802 to move. The locking frame 802 moves in the connecting hole 803 and is inserted in the locking groove 804 to move, thereby locking the protective box 9 on the processing table 2, effectively avoiding the problem of the protective box 9 being accidentally opened during processing, and ensuring the normal progress of the processing work.
