Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a double wire cutting device. Background Art

[0002] Electrical discharge wire cutters are widely used in processing electrodes, processing flat dies made of hard materials (such as cemented carbide, alloy tool steel, etc.), cutting parts with complex shapes having spatial curved surfaces and taper parts, precision complex small workpieces, and medium and small metal parts, etc.

[0003] In electrical discharge cutting, wire cutting wires made of copper wire or molybdenum wire are usually used for cutting. For copper wire, it is usually used on numerically controlled low-speed wire cutting machine tools. The surface of the copper wire is smooth, but its wear resistance is weak, and its price is relatively lower than that of molybdenum wire, which is suitable for processes with high cutting accuracy. For manufacturers with only one piece of equipment, copper wire is still used for roughing operations. When the copper wire is used for roughing, it needs to be cooled by high-pressure pure water. At this time, since the water does not have a lubricating effect, the resistance of the copper wire is relatively large, and the temperature of the water will rise. If copper wire is used for roughing, the cooling of pure water will increase energy consumption.

[0004] For molybdenum wire, the melting point of molybdenum is very high, reaching about 2610 degrees Celsius. Therefore, it can maintain stability in a high-temperature environment, is not easy to melt and break, and the molybdenum wire has excellent strength, hardness and wear resistance, enabling it to better maintain a straight state during the cutting process and usually can be cut multiple times. However, after multiple cuts, the surface of the molybdenum wire cannot maintain a smooth state, so the cutting of the workpiece is not very smooth either. Therefore, molybdenum wire is usually used for processes with low cutting accuracy.

[0005] Users need different accuracies of cutting for the processing states of workpieces at different times. Users need to cut on cutting devices equipped with different wire cutting wires. At this time, users need to purchase multiple pieces of equipment, which greatly increases the production cost of users. The workpiece also needs to be transported multiple times, affecting the production efficiency. Summary of the Utility Model

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0081] As Figures 1-8 shown, a double wire cutting device includes a support column (1), a first wire winding device (2), a second wire winding device (15), a third wire winding device (3), a tensioning device, a placement table (5), and a wire cutting head (6);

[0082] The first wire winding device (2) and the second wire winding device (15) are arranged on the same side of the support column (1). The first wire winding device (2) stores molybdenum wire, and the second wire winding device (15) stores copper wire;

[0083] The third wire winding device (3) is arranged on the other side of the support column (1). The third wire winding device (3) is provided with a wire clamping member for clamping molybdenum wire;

[0084] The placement table (5) is fixedly arranged on the support column (1) and is on the same side as the first wire winding device (2). The placement table (5) is used for placing the object to be cut;

[0085] The wire cutting head (6) is fixedly arranged on the support column (1) and is on the same side as the first wire winding device (2). The wire cutting head (6) is used for cutting the object to be cut;

[0086] The tensioning device includes a first tensioning member and a second tensioning member (11). The first tensioning member (14) is on the same side as the first wire winding device (2), and the second tensioning member (11) is on the same side as the third wire winding device (3);

[0087] When using molybdenum wire for cutting, the molybdenum wire passes through the first wire winding device (2), the first tensioning member (14), the wire cutting head (6), the object placing table (5), the second tensioning member (11), and the third wire winding device (3) in sequence;

[0088] When using copper wire for cutting, the copper wire passes through the second wire winding device (15), the first tensioning member (14), the wire cutting head (6), the object placing table (5), and the second tensioning member (11) in sequence.

[0089] In the present utility model, in order to reduce the number of purchased devices, a first wire winding device (2) and a second wire winding device (15) are arranged on one side of the support column. Molybdenum wire and copper wire are respectively wound on them.

[0090] When a workpiece needs to be rough cut, the second wire winding device (15) can retract the copper wire, and the molybdenum wire is pulled out from the first wire winding device (2) and introduced into the first tensioning member (14), the wire cutting head (6), the object placing table (5), the second tensioning member (11), and the third wire winding device (3) in sequence. A wire clamping member is arranged on the third wire winding device (3). The wire clamping member is a clip for clamping molybdenum wire in the prior art. Under the clamping action of the wire clamping member and the tensioning of the tensioning device, the molybdenum wire can maintain a tensioned state. When the molybdenum wire is electrified at the wire cutting head (6), the molybdenum wire can accurately cut the object. When cutting with the molybdenum wire, a water-soluble working fluid needs to be sprayed at the wire cutting mechanism (6) to ensure better surface lubrication of the molybdenum wire for cutting the object. Compared with rough cutting with copper wire, the combination of molybdenum wire and water-soluble working fluid has better brittleness and lubricity, and reduces the energy consumption during water cooling when using copper wire for rough cutting. After the wire cutting head (6) is electrified, the first wire winding device (2) and the second wire winding device (15) are controlled by a program so that the molybdenum wire can maintain a tensioned state, and the molybdenum wire can wind and collect back and forth between the first wire winding device (2) and the second wire winding device (15) during cutting, ensuring that the high-price molybdenum wire can be reused.

[0091] After the workpiece is rough machined, finish cutting is required. At this time, a copper wire needs to be used for cutting. The user can loosen the wire clamping member and then rotate the first wire winding device (2) so that the first wire winding device (2) rotates to recover the molybdenum wire. After the first wire winding device (2) has collected the molybdenum wire. In the second wire winding device (15), the copper wire is sequentially introduced into the first tensioning member (14), the wire cutting head (6), the placement table (5), and the second tensioning member (11). Through the pulling between the first tensioning member (14) and the second tensioning member (11), the copper wire can be kept in a tensioned state. After the wire cutting head (6) is powered on, the object can be cut. Since the service life of the copper wire is relatively low and the price is relatively low, it is not necessary to use the third wire winding device (3) to collect the copper wire after cutting. The cut copper wire can be directly discharged into the waste bucket (17). When cutting with the copper wire, high-pressure pure water needs to be supplied to the wire cutting mechanism. Since finish cutting is performed with the copper wire at this time.

[0092] When the molybdenum wire is used again, the corresponding copper wire can be cut short at the second wire winding device (15), and the molybdenum wire can be continuously drawn out from the first wire winding device (2) and clamped in the wire clamping member immediately.

[0093] The structure proposed by the present utility model can reduce the investment in setting. In one device, molybdenum wire cutting or copper wire cutting can be alternately replaced according to the cutting requirements, greatly reducing the investment in production costs, and at the same time improving the adaptability of the device to different cutting requirements.

[0094] In addition, the first wire winding device (2) and the second wire winding device (15) are arranged on the same side of the support column (1), which is convenient for the operator to replace the wire cutting wire (4) and improves the convenience of using the device.

[0095] Preferably, a connecting arm (8) extending forward is provided at the top of the support column (1).

[0096] Both the first mounting plate (9) and the second mounting plate (16) are located above the placement table (5).

[0097] Adopting the above structure can extend the horizontal distance between the support column (1) and the wire cutting head (6), making the operating space below the wire cutting head (6) larger, which is convenient for the wire cutting device to perform wire cutting on large workpieces to be processed.

[0098] It is worth mentioning that a cutting wire roller (10) is provided between the first wire winding device (2) and the wire cutting head. The wire cutting wire (4) passes out of the wire cutting head, passes through the cutting wire roller (10) and the moving guiding device (7), and is fixed to the first wire winding device (2).

[0107] The molybdenum wire needs to be wound layer by layer on the surface of the wire winding device. For this purpose, the existing wire winding device is provided with a moving mechanism.

However, in the present invention, the first wire winding device (2) is arranged on the first mounting plate (9), and the mounting portion and the support column (1) are not a whole. There is a force restriction on the first mounting plate (9). In order to reduce the gravity on the first mounting plate (9), in the present invention, the moving guide device (7) is provided.

A wire arranging component (7e) is fixed on the first slider (7b). The wire arranging component (7e) is tensioned with a wire cut wire (4). At this time, the wire cut wire (4) moves up and down driven by the wire arranging component (7e). The first wire winding device (2) can also wind the wire cut wire (4) layer by layer on its surface only by rotating, without causing overlap or knotting of the wire cut wire (4), ensuring the normal operation of the device.

[0116] The rear wire storage cylinder driving member (3cc) is fixed at one end of the rear wire storage cylinder rotating seat (3ca), and one end of the rear wire storage cylinder (3a) is connected to the driving end of the rear wire storage cylinder driving member (3cc); the rear transmission gear set (3cd) is arranged at the other end of the rear wire storage cylinder rotating seat (3ca), and the other end of the rear wire storage cylinder (3a) is in transmission connection with the input end of the rear transmission gear set (3cd);

[0117] The rear wire storage cylinder mounting seat (3b) is provided with a rear lead screw mounting seat (3ba).

The output end of the rear transmission gear set (3cd) is in transmission connection with the rear wire storage cylinder transmission lead screw (3ce); the rear wire storage cylinder transmission lead screw (3ce) is in threaded connection with the rear wire storage cylinder sliding block (3cf);

[0118] The rear wire storage cylinder sliding block (3cf) and the rear wire storage cylinder guide rail strip (3cg) are respectively installed on the top of the rear wire storage cylinder mounting seat (3b); the rear guide rail seat (3ch) is arranged at the bottom of the rear wire storage cylinder sliding seat (3cb), and the rear guide rail seat (3ch) is slidably assembled on the rear wire storage cylinder guide rail strip (3cg).

[0119] In a specific embodiment of the present utility model, the rear transmission gear set (3cd) includes a first transmission gear, a second transmission gear, and a third transmission gear; the first transmission gear is the input end of the rear transmission gear set (3cd), and the third transmission gear is the output end of the rear transmission gear set (3cd); the first transmission gear is sleeved on the other end of the rear wire storage cylinder (3a), the first transmission gear meshes with the second transmission gear, and the second transmission gear meshes with the third transmission gear; the rear wire storage cylinder transmission lead screw (3ce) meshes with the third transmission gear, thereby achieving the purpose of transmission. When the rear wire storage cylinder driving member (3cc) drives the rear wire storage cylinder (3a) to rotate, it drives the first transmission gear, the second transmission gear, and the third transmission gear to rotate in sequence, thereby driving the rear wire storage cylinder transmission lead screw (3ce) to rotate; through the lead screw transmission structure of the rear wire storage cylinder transmission lead screw (3ce) and the rear wire storage cylinder sliding block (3cf), the rear wire storage cylinder sliding seat (3cb) is driven to move along the Z-axis direction.

[0120] The rear wire storage cylinder guide bar (3cg) and the rear guide seat (3ch) play a role of limiting and guiding, enabling the rear wire storage cylinder sliding seat (3cb) to move along the Z-axis direction, preventing the rear wire storage cylinder sliding seat (3cb) from moving in other directions, and improving the stability of the rear wire storage cylinder driving assembly (3c).

[0121] The above structure is simple and the transmission is stable. While the rear wire storage cylinder (3a) rotates, it can move along the Z-axis direction, enabling the wire cutting wire (4) to be automatically and neatly wound around the rear wire storage cylinder (3a), improving the winding efficiency of the rear wire storage cylinder (3a), and preventing the wire cutting wires (4) from overlapping with each other.

[0122] Adopting the above structure, while the rear wire storage cylinder (3a) rotates, it can move along the length axis direction of the rear wire storage cylinder mounting seat (3b), enabling the wire cutting wire (4) to be automatically and neatly released from the rear wire storage cylinder (3a), preventing the wire cutting wire (4) from being pulled during the unwinding process due to the fixation of the wire storage cylinder, resulting in inconsistent local tension of the wire cutting wire (4) and affecting the cutting effect.

[0123] Preferably, the second wire winding device (15) includes a copper wire winding disc (15a) rotatably arranged on the second mounting plate (16) and a plurality of guide wheels (15b). The copper wire winding disc (15a) is used for storing copper wire, and the copper wire is led out from the copper wire winding disc (15a) and wound around the outer circumferential surfaces of the plurality of guide wheels (15b).

[0124] Since the copper wire is highly flexible, it needs to be kept in a tensioned state during cutting. Therefore, in the utility model, a plurality of guide wheels (15b) are provided, and a plurality of guide wheels (15b) are staggered up and down, and the copper wires are respectively wound around the surfaces of the guide wheels (15b), so that the copper wires can be kept in a tensioned state before being straightened by the first tensioning member (14), thereby facilitating the lead-in of the copper wire and ensuring the quality of cutting.

[0125] Preferably, the wire cutting machine head (6) comprises a connecting block (6a), a guide column (6b), a machine head driving device (6c), a lifting plate (6d), a second guide rail (6e), a second slide block (6f), and a second steering guide wheel (6g);

[0128] The lower end of the guide column (6b) is connected to the lifting plate (6d), and the lifting plate (6d) is provided with a second threading nozzle (6da); the second steering guide wheel (6g) is arranged on the other side of the guide column (6b);

[0129] The first tensioning member (14) comprises a second driving motor (14a), a second conductive block (14b), a second driving wheel (14c), a mounting column (14e) and a second driven wheel (14d);

[0130] The mounting column (14e) is fixedly mounted on the lifting plate (6d);

[0132] The other end of the wire cutting wire (4) passes through the second wire threading nozzle (6da), the second conductive block (14b), and passes through the gap between the second driving pulley (14c) and the second driven pulley (14d). After the wire cutting wire (4) is tangent to the second turning guide pulley (6g), it is connected to the first wire winding device (2) or the second wire winding device (15).

[0133] The connecting block (6a) is fixed to the connecting arm (8). When the lifting head of the wire cutting machine needs to rise, the machine head driving device (6c) drives the second guide rail (6e) and the guide post (6b) to move upward, so that the second guide rail (6e) has an upward displacement relative to the second slider (6f); the guide post (6b) drives the lifting plate (6d) to move upward, increasing the horizontal height of the lifting plate (6d). Conversely, when the lifting head of the wire cutting machine needs to descend, the machine head driving device (6c) drives the second guide rail (6e) and the guide post (6b) to move downward, so that the second guide rail (6e) has a downward displacement relative to the second slider (6f), and the guide post (6b) drives the lifting plate (6d) to move downward, reducing the horizontal height of the lifting plate (6d). With the above structure, the distance between the first wire threading nozzle (11da) and the second wire threading nozzle (6da) can be reduced by the machine head driving device (6c), facilitating the wire threading operation for the staff.

[0134] The second turning guide pulley (6g) plays a role in tensioning and guiding, enabling the wire cutting wire (4) to turn from the Z-axis direction to the X-axis direction, so that it can be wound around the first wire winding device (2).

[0135] The first tensioning member (14) plays a role in tensioning the wire cutting wire (4) and assisting the first wire winding device (2) in winding the wire cutting wire (4). The wire cutting wire (4) passes through the gap between the second driving pulley (14c) and the second driven pulley (14d). The second driving motor (14a) can drive the second driving pulley (14c) to rotate. Through the frictional force between the second driving pulley (14c) and the wire cutting wire (4), and between the wire cutting wire (4) and the second driven pulley (14d), the purpose of tensioning the wire cutting wire (4) or driving the wire cutting wire (4) to move towards the first wire winding device (2) is achieved. The second conductive block (14b) can be energized with the second wire threading nozzle (6da), and the second wire threading nozzle heats the wire cutting wire (4), so that the wire cutting wire (4) can have the ability to cut objects.

[0136] The machine head driving device (6c) includes a motor mounting plate (6ca), a fixed seat (6cb), a machine head motor (6cc), a driven gear (6cd), a second lead screw (6ce), and a driving block (6cf);

[0137] The motor mounting plate (6ca) is connected to the upper end of the guide post (6b). The fixed seat (6cb) is arranged on the top surface of the motor mounting plate (6ca). The head motor (6cc) is fixed to the fixed seat (6cb). A driving gear is provided at the output end of the head motor (6cc). The driven gear (6cd) is sleeved on the upper end of the second lead screw (6ce) and meshes with the driving gear. The second lead screw (6ce) is rotatably connected to the motor mounting plate (6ca). A threaded hole is provided on the driving block (6cf), and the second lead screw (6ce) is threadedly connected to the threaded hole. The driving block (6cf) is connected to the connecting block (6a).

[0138] When the head motor (6cc) rotates, the output end of the head motor (6cc) drives the driving gear to rotate. At this time, the driven gear (6cd) and the lead screw nut also rotate accordingly. Since the second lead screw (6ce) is threadedly connected to the threaded hole of the driving block (6cf), and the second lead screw (6ce) is rotatably connected to the mounting plate, at this time, the mounting plate, the lifting rod and the head driving device (6c) move up and down relative to the guide post (6b), so as to achieve the purpose of lifting. The above structure is simple and the transmission is stable.

[0139] Preferably, the second tensioning member (11) includes a guide arm (11a). The guide arm (11a) includes a guide arm body, a first turning guide wheel (11b), a first conductive block (11c) and a wire threading plate (11d).

The wire threading plate (11d) is provided with a first wire threading nozzle (11da). After the other end of the wire cutting wire (4) enters the avoidance groove (11e), it passes through the gap between the first turning guide wheel (11b) and the first conductive block (11c), and passes out from the first wire threading nozzle (11da) and enters the wire cutting head (6).

[0141] The guiding arm (11a) guides the movement direction of the wire cut-off wire (4), cooperates with the forward-extending connecting arm (8), increases the moving space of the workpiece to be processed, and facilitates wire cutting. The first conductive block (11c) cooperates with the second conductive block (14b) of the wire cutting machine head (6), so that the wire cut-off wire (4) is energized. The first turning guide wheel (11b) plays a role in turning, so that the wire cut-off wire (4) turns from the X-axis direction to the Z-axis direction, so that the wire cut-off wire (4) can smoothly enter the wire cutting machine head (6). The first wire threading nozzle (11da) plays a role in positioning, preventing the wire cut-off wire (4) from shifting, so that the wire cut-off wire (4) can be aligned with the second wire threading nozzle (6da) of the wire cutting machine head (6).

[0142] The second tensioning member (11) is further provided with a first driving assembly (12) and a secondary guide wheel (13). The first driving assembly (12) is arranged at the rear side of the guiding arm body, and the secondary guide wheel (13) is arranged between the first driving assembly (12) and the guiding arm body;

[0143] The first driving assembly (12) includes a connecting seat (12a), a first driving motor (12b), a first driving wheel (12c) and a first driven wheel (12d); the connecting seat (12a) is fixed to the support column (1); the connecting seat (12a) is provided with a wire channel (12aa) along the X-axis direction, and the connecting seat (12a) is provided with a roller groove (12e) penetrating the wire channel (12aa) along the Z-axis direction; the first driving wheel (12c) and the first driven wheel (12d) are respectively rotatably installed in the roller groove (12e); the first driving motor (12b) is fixed to the connecting seat (12a), and the driving end of the first driving motor (12b) passes through the connecting seat (12a) and is drivingly connected to the first driving wheel (12c);

[0144] After the other end of the wire cut-off wire (4) enters the wire channel (12aa), it passes through the gap between the first driving wheel (12c) and the first driven wheel (12d), and the wire cut-off wire (4) enters the avoidance groove (11e) after being tangent to the secondary guide wheel (13).

[0145] The first driving assembly (12) plays a role in tensioning the wire cut-off wire (4) and assisting the third wire winding device (3) to release the wire cut-off wire (4). The wire cut-off wire (4) passes through the gap between the first driving wheel (12c) and the first driven wheel (12d). The first driving motor (12b) can drive the first driving wheel (12c) to rotate, and through the friction force between the first driving wheel (12c) and the wire cut-off wire (4), and between the wire cut-off wire (4) and the first driven wheel (12d), the purpose of tensioning the wire cut-off wire (4) or driving the wire cut-off wire (4) to come out from the third wire winding device (3) is achieved.

[0146] Preferably, a waste bin (17) is provided on the side of the third wire winding device (3) facing away from the support column (1).

[0147] Since the copper wire is usually used only once, after use, the copper wire can pass through the surface of the third wire winding device (3) and then fall into the waste bin (17) for collection, thereby improving the cleanliness during production and the convenience of waste collection.

[0148] Preferably, the wire discharging component (7e) includes a mounting block (7ea) and a wire discharging wheel (7eb). The mounting block (7ea) is fixed to the first slider (7b). A wire discharging wheel (7eb) is rotatably mounted on the side of the mounting block facing away from the first slider (7b). The molybdenum wire is wound around the wire discharging wheel (7eb).

[0149] In an embodiment of the present invention, the molybdenum wire is tensioned by the wire discharging wheel (7eb). The wire discharging wheel (7eb) is rotatably mounted on the mounting block (7ea) through a rotating shaft (7eba). When the first wire winding device (2) rotates, the wire discharging wheel (7eb) will also be driven by the molybdenum wire to rotate, reducing the friction between the molybdenum wire and the wire discharging wheel (7eb), thereby reducing the wear of the molybdenum wire and improving the service life of the molybdenum wire. The first slider (7b) can be detachably installed on the first slider (7b). When different diameters of molybdenum wires need to be replaced under different cutting environments, the corresponding mounting block can be disassembled and different wire discharging wheels (7eb) can be replaced, so as to ensure that the molybdenum wire can be effectively tensioned on the wire discharging wheel (7eb).

[0150] The wire discharging wheel (7eb) includes a rotating shaft (7eba) and a wheel (7ebb).

[0151] The rotating shaft (7eba) is fixed to the mounting block (7ea) through a bearing, and the rotating shaft (7eba) protrudes from the mounting block (7ea).

The width of the groove (7ebc) is greater than the diameter of the molybdenum wire. The molybdenum wire is wound in the groove (7ebc).

[0152] Since the molybdenum wire needs to be frequently replaced, and in order to prevent the molybdenum wire from detaching from the wheel (7ebb), the molybdenum wire usually winds around the wheel (7ebb) for one circle and then extends out of the wheel (7ebb). In order to facilitate the installation of the molybdenum wire more conveniently, in the present utility model, a groove (7ebc) is provided on the outer circumferential surface of the wheel (7ebb). The width of the groove (7ebc) matches the diameter of the molybdenum wire and is slightly larger than the diameter of the molybdenum wire. When replacing or installing the molybdenum wire, only need to put the molybdenum wire into the groove (7ebc), and the left and right side walls of the groove (7ebc) will limit the left and right sides of the molybdenum wire to prevent the molybdenum wire from detaching. At this time, there is no need to wind the molybdenum wire around the wheel (7ebb), which greatly improves the efficiency of replacing or installing the molybdenum wire.
