Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment structure design and application technology of wire cutting devices, and in particular to a device for rapid flipping and alternating use of wire cutting conductive blocks. Background Technology
[0002] Currently, most conductive blocks on the market rely on manual replacement and flipping of the contact surfaces, which is cumbersome. Disassembling and replacing conductive blocks also reduces work efficiency, and when large-scale continuous operations are required, the continuity of operation is affected by changing and flipping the contact surfaces.
[0003] There is an urgent need for a device that allows for the rapid flipping and alternating use of wire-cut conductive blocks with excellent technical performance. Utility Model Content
[0004] This invention provides a device for the rapid flipping and alternating use of wire-cut conductive blocks.
[0005] The technical solution of this utility model is as follows:
[0006] A device for rapidly flipping and alternating use of wire-cut conductive blocks is provided for fixing conductive blocks 10 and performing face-changing operations on conductive blocks 10. The key technical aspect is that the device comprises a ratchet unit and a fixing device 1. Specifically, there is at least one ratchet unit; the fixing device 1 is used to fix the ratchet unit on the wire-cutting equipment; the conductive block 10 is arranged in the ratchet unit and can be adjusted by the ratchet unit to perform face-changing operations.
[0007] The ratchet unit includes a ratchet 2, a ratchet reversing lever 3, and tooth stops 9. The ratchet reversing lever 3 is a structure that can set or change the allowed rotation direction of the ratchet 2. There are two tooth stops 9 used to limit the ratchet 2 to rotate only clockwise or only counterclockwise. The two work together to limit the ratchet 2 to rotate only in a single direction. The allowed rotation direction of the ratchet 2 can be set or changed by operating the ratchet reversing lever 3. When the ratchet reversing lever 3 is in one of the positions, the allowed rotation direction of the ratchet 2 is already set to only one allowed rotation direction. Rotating the ratchet reversing lever 3 to the left causes the right tooth stop 9 to contact the ratchet teeth, and the left tooth stop 2 to separate from the ratchet teeth, so that the ratchet can only rotate counterclockwise. Rotating the ratchet reversing lever 3 to the right causes the left tooth stop 2 to contact the ratchet teeth, and the right tooth stop 9 to separate from the ratchet teeth, so that the ratchet can only rotate clockwise.
[0008] Figure 3 The middle gear stop 9 is in contact with the gear, the gear stop 2 is not in contact with the gear, and the ratchet reversing lever 3 is already at the far left.
[0009] In the wire cutting conductive block rapid flipping and alternating use device, the fixing device 1 is a fastening hexagonal screw, which can fix the ratchet unit on the wire cutting equipment.
[0010] The preferred technical content to be protected in the wire EDM conductive block quick-flipping and alternating use device of this utility model is: in the wire EDM conductive block quick-flipping and alternating use device, the fixing device 1 is an M6 external hexagonal screw for fastening.
[0011] The wire cutting conductive block rapid flipping and alternating use device is also provided with a connecting rod 7, and at least two ratchet units are fixed on the connecting rod 7 at the same time. One ratchet unit is fixedly arranged at the working position of the conductive block 10 of the wire cutting equipment, and the other ratchet units are connected to the ratchet units arranged at the working position of the conductive block 10 of the wire cutting equipment through the connecting rod 7.
[0012] The ratchet reversing lever 3 includes a rotating shaft 3.1, a pointer 3.2, and a "V"-shaped stop lever posture changing component 3.3; wherein: the three rotate synchronously; the two switching positions of the pointer correspond to the two allowable rotation directions of the ratchet 2 respectively; the ratchet reversing lever 3 can ensure that only one tooth stop lever 9 is in the working posture.
[0013] After pre-tightening installation, the included angle between the left and right parts of the "V"-shaped stop lever attitude changer 3.3 located on the rotation axis 3.1 is 84.2° to 87.5°. This is the optimal parameter range after testing, which can effectively guarantee the service life and technical performance of the "V"-shaped stop lever attitude changer 3.3.
[0014] The wire-cut conductive block rapid flipping and alternating use device has three ratchet devices, which are fixedly connected together by a connecting rod 7; the outer ring of the ratchet 2 cannot rotate, while the inner ring of the ratchet 2 is a structure that can be rotated by manipulating the internal hexagon head; if the tooth stop bar 6 of the ratchet 2 is not present, the conductive block 10 fixed to the ratchet device by the hexagonal bolt can be rotated arbitrarily.
[0015] The external hexagonal bolt used for fixing the fixing device 1 passes through the central hole of the conductive block 10, and the other end is fixed by the nut 11. The conductive block 10 fixed on the fixing device 1 is fixed by the external hexagonal end of the external hexagonal bolt to the internal hexagonal hole between the ratchet device B5 and the ratchet device C6, i.e., at the ratchet device A4. This tight fit between the internal and external hexagons enables a quick and convenient way to disassemble the conductive block 10. Moreover, the ratchet device B5 on the left and the ratchet device C6 on the right are one end lower and the other end higher. Therefore, after the conductive block 10 is installed by the ratchet device B5 and the ratchet device C6 in this way, rotating the middle ratchet device A4 will make the conductive block 10 on the right ratchet device C6 contact the wire-cut molybdenum wire. The conductive block 10 on the left ratchet device B5 will not contact the wire-cut molybdenum wire at its current position, thus not affecting the cutting work.
[0016] The conductive block 10 is a cylindrical structure with an internal cavity, with an axial length of 38–42 mm, an inner diameter of 7–10 mm, and an outer diameter of 20–24 mm. The conductive block 10, which meets these macroscopic dimensional requirements, perfectly satisfies the relevant requirements and offers the best cost performance.
[0017] The wire cutting conductive block quick-flip alternating device meets the following requirements: the middle ratchet device, namely ratchet device A4, among the three ratchet devices, is fixed to the wire cutter by an external hex bolt, which serves as a fixing device 1, and the connecting rod 7 is lower on the left and higher on the right, with the left ratchet device B5 being lower than the right ratchet device C6; when the ratchet reversing rod 3 is rotated while the middle ratchet device A4 fixed to the wire cutter is rotated, the actual ratchet device in use can be switched.
[0018] The center distance between the ratchet device B5 on the left side of connecting rod 7 and the ratchet device A4 in the center is 205-218mm, and the center distance between the ratchet device C6 on the oil side of connecting rod 7 and the ratchet device A4 in the center is 256-266mm. This is to balance the convenience of switching the ratchet devices actually in use, reducing equipment interference, and also to ensure safety.
[0019] The wire-cut conductive block rapid flipping and alternating use device meets one or a combination of the following requirements:
[0020] Firstly, among the three ratchet devices, the middle ratchet device, namely ratchet device A4, is fixed to the wire cutter by an external hexagonal bolt, which serves as a fixing device 1, and does not contact the molybdenum wire. Furthermore, the connecting rod 7 is lower on the left and higher on the right, with the left ratchet device B5 being lower than the right ratchet device C6. When the ratchet reversing rod 3 is rotated while the middle ratchet device A4, which is fixed to the wire cutter, is rotated, the ratchet device actually in use can be switched. For example, the conductive block 10 on the left ratchet device B5 can be changed to not contact the molybdenum wire, while the conductive block 10 on the right ratchet device C6 can start to contact the molybdenum wire to achieve conductivity.
[0021] Secondly, when one side of the conductive block 10 fixed on the wire cutter by the ratchet device C6 is severely worn, by rotating the ratchet reversing lever 3, the ratchet device A4 fixed on the wire cutter in the middle is rotated, so that the conductive block 10 on the ratchet device B5 comes into contact with the wire cutter molybdenum wire, and the conductive block 10 on the ratchet device C6 is separated from the molybdenum wire, thereby realizing the alternating use of the conductive block 10.
[0022] The ratchet reversing lever 3 on the rotating ratchet device C6 allows the conductive block 10, which is fixed to the ratchet device C6 by hexagonal bolts, to rotate clockwise or counterclockwise. This enables the conductive block 10 to be quickly flipped without affecting the cutting process, thus changing the working surface of the conductive block 10.
[0023] The wire cutting conductive block rapid flipping and alternating use device is also equipped with a connecting rod 7, and at least two ratchet units are fixed on the connecting rod 7 at the same time, one of which is fixedly arranged at the conductive block working position of the wire cutting equipment.
[0024] This invention enables the rapid replacement of the contact surface after wear of the conductive block, and the replacement of the unusable conductive block with another conductive block, achieving the purpose of alternating use and rapid replacement of conductive blocks without affecting processing efficiency.

[0030] The present invention will be further described below with reference to the embodiments and the accompanying drawings, but is not limited thereto.
[0031] Example 1
[0032] A device for rapidly flipping and alternating conductive blocks in wire cutting is used to fix conductive blocks 10 and perform face-changing operations on conductive blocks 10; it includes a ratchet unit and a fixing device 1; wherein: there is at least one ratchet unit; the fixing device 1 is used to fix the ratchet unit on the wire cutting equipment; the conductive block 10 is arranged in the ratchet unit and can perform face-changing operations under the adjustment of the ratchet unit;
[0033] The ratchet unit includes a ratchet 2, a ratchet reversing lever 3, and tooth stops 9. The ratchet reversing lever 3 is a structure that can set or change the allowed rotation direction of the ratchet 2. There are two tooth stops 9 used to limit the ratchet 2 to rotate only clockwise or only counterclockwise. The two work together to limit the ratchet 2 to rotate only in a single direction. The allowed rotation direction of the ratchet 2 can be set or changed by operating the ratchet reversing lever 3. When the ratchet reversing lever 3 is in one of the positions, the allowed rotation direction of the ratchet 2 is already set to only one allowed rotation direction. Rotating the ratchet reversing lever 3 to the left causes the right tooth stop 9 to contact the ratchet teeth, and the left tooth stop 2 to separate from the ratchet teeth, so that the ratchet can only rotate counterclockwise. Rotating the ratchet reversing lever 3 to the right causes the left tooth stop 2 to contact the ratchet teeth, and the right tooth stop 9 to separate from the ratchet teeth, so that the ratchet can only rotate clockwise.
[0034] Figure 3 The middle gear stop 9 is in contact with the gear, the gear stop 2 is not in contact with the gear, and the ratchet reversing lever 3 is already at the far left.
[0035] In the wire cutting conductive block rapid flipping and alternating use device, the fixing device 1 is a fastening hexagonal screw, which can fix the ratchet unit on the wire cutting equipment.
[0036] In the device for rapid flipping and alternating use of the wire-cut conductive block, the fixing device 1 is an M6 external hexagonal screw for fastening.
[0037] The wire cutting conductive block rapid flipping and alternating use device is also provided with a connecting rod 7, and at least two ratchet units are fixed on the connecting rod 7 at the same time. One ratchet unit is fixedly arranged at the working position of the conductive block 10 of the wire cutting equipment, and the other ratchet units are connected to the ratchet units arranged at the working position of the conductive block 10 of the wire cutting equipment through the connecting rod 7.
[0038] The ratchet reversing lever 3 includes a rotating shaft 3.1, a pointer 3.2, and a "V"-shaped stop lever posture changing component 3.3; wherein: the three rotate synchronously; the two switching positions of the pointer correspond to the two allowable rotation directions of the ratchet 2 respectively; the ratchet reversing lever 3 can ensure that only one tooth stop lever 9 is in the working posture.
[0039] After pre-tightening installation, the included angle between the left and right parts of the "V"-shaped stop lever attitude changer 3.3 located on the rotation axis 3.1 is 84.2° to 87.5°. This is the optimal parameter range after testing, which can effectively guarantee the service life and technical performance of the "V"-shaped stop lever attitude changer 3.3.
[0040] The wire-cut conductive block rapid flipping and alternating use device has three ratchet devices, which are fixedly connected together by a connecting rod 7; the outer ring of the ratchet 2 cannot rotate, while the inner ring of the ratchet 2 is a structure that can be rotated by manipulating the internal hexagon head; if the tooth stop bar 6 of the ratchet 2 is not present, the conductive block 10 fixed to the ratchet device by the hexagonal bolt can be rotated arbitrarily.
[0041] The external hexagonal bolt used for fixing the fixing device 1 passes through the central hole of the conductive block 10, and the other end is fixed by the nut 11. The conductive block 10 fixed on the fixing device 1 is fixed by the external hexagonal end of the external hexagonal bolt to the internal hexagonal hole between the ratchet device B5 and the ratchet device C6, i.e., at the ratchet device A4. This tight fit between the internal and external hexagons enables a quick and convenient way to disassemble the conductive block 10. Moreover, the ratchet device B5 on the left and the ratchet device C6 on the right are one end lower and the other end higher. Therefore, after the conductive block 10 is installed by the ratchet device B5 and the ratchet device C6 in this way, rotating the middle ratchet device A4 will make the conductive block 10 on the right ratchet device C6 contact the wire-cut molybdenum wire. The conductive block 10 on the left ratchet device B5 will not contact the wire-cut molybdenum wire at its current position, thus not affecting the cutting work.
[0042] The conductive block 10 is a cylindrical structure with an internal cavity, with an axial length of 38–42 mm, an inner diameter of 7–10 mm, and an outer diameter of 20–24 mm. The conductive block 10, which meets these macroscopic dimensional requirements, perfectly satisfies the relevant requirements and offers the best cost performance.
[0043] The wire cutting conductive block quick-flip alternating device meets the following requirements: the middle ratchet device, namely ratchet device A4, among the three ratchet devices, is fixed to the wire cutter by an external hex bolt, which serves as a fixing device 1, and the connecting rod 7 is lower on the left and higher on the right, with the left ratchet device B5 being lower than the right ratchet device C6; when the ratchet reversing rod 3 is rotated while the middle ratchet device A4 fixed to the wire cutter is rotated, the actual ratchet device in use can be switched.
[0044] The center distance between the ratchet device B5 on the left side of connecting rod 7 and the ratchet device A4 in the center is 205-218mm, and the center distance between the ratchet device C6 on the oil side of connecting rod 7 and the ratchet device A4 in the center is 256-266mm. This is to balance the convenience of switching the ratchet devices actually in use, reducing equipment interference, and also to ensure safety.
[0045] The wire-cut conductive block rapid flipping and alternating use device satisfies the following combination of requirements:
[0046] Firstly, among the three ratchet devices, the middle ratchet device, namely ratchet device A4, is fixed to the wire cutter by an external hexagonal bolt, which serves as a fixing device 1, and does not contact the molybdenum wire. Furthermore, the connecting rod 7 is lower on the left and higher on the right, with the left ratchet device B5 being lower than the right ratchet device C6. When the ratchet reversing rod 3 is rotated while the middle ratchet device A4, which is fixed to the wire cutter, is rotated, the ratchet device actually in use can be switched. For example, the conductive block 10 on the left ratchet device B5 can be changed to not contact the molybdenum wire, while the conductive block 10 on the right ratchet device C6 can start to contact the molybdenum wire to achieve conductivity.
[0047] Secondly, when one side of the conductive block 10 fixed on the wire cutter by the ratchet device C6 is severely worn, by rotating the ratchet reversing lever 3, the ratchet device A4 fixed on the wire cutter in the middle is rotated, so that the conductive block 10 on the ratchet device B5 comes into contact with the wire cutter molybdenum wire, and the conductive block 10 on the ratchet device C6 is separated from the molybdenum wire, thereby realizing the alternating use of the conductive block 10.
[0048] The ratchet reversing lever 3 on the rotating ratchet device C6 allows the conductive block 10, which is fixed to the ratchet device C6 by hexagonal bolts, to rotate clockwise or counterclockwise. This enables the conductive block 10 to be quickly flipped without affecting the cutting process, thus changing the working surface of the conductive block 10.
[0049] The wire cutting conductive block rapid flipping and alternating use device is also equipped with a connecting rod 7, and at least two ratchet units are fixed on the connecting rod 7 at the same time, one of which is fixedly arranged at the conductive block working position of the wire cutting equipment.
[0050] This embodiment enables the rapid replacement of the contact surface after wear of the conductive block, and the replacement of the conductive block with another conductive block when the conductive block becomes unusable, thus achieving the purpose of alternating use and rapid replacement of conductive blocks without affecting processing efficiency.
[0051] Example 2
[0052] A device for rapid flipping and alternating use of conductive blocks in wire cutting includes a bolt 1, a ratchet 2, a ratchet reversing lever 3, a ratchet assembly A4, a ratchet assembly B5, a ratchet assembly C6, a connecting rod 7, and ratchet teeth 8. The ratchet assembly A4 is fixed to the wire cutting equipment primarily by a hexagonal bolt 1 (which is an external hexagonal bolt). The ratchet reversing lever 3 enables the connecting rod 7 to move upwards or downwards. Furthermore, the reverse braking at the ratchet reversing lever 3 allows the conductive block 10 on either ratchet assembly B5 or ratchet assembly C6 to contact the molybdenum wire, achieving a fixing effect through contact between the ratchet teeth 8 and the tooth stop bar 9, thus ensuring conductivity.
[0053] This embodiment enables rapid replacement of worn conductive blocks in wire EDM, and allows for direct removal and replacement of worn conductive blocks 10 on the ratchet device B5 without affecting the cutting progress. The conductive block 10 is fixed by passing its central hole through the threaded portion of the bolt 1. The bolt 1 is then connected to both the ratchet device B5 and ratchet device C6, thus connecting and securing the conductive block 10 to the ratchet device. Since the conductive block 10 is fixed to the hexagonal bolt 1, the ratchet reversing lever 3 rotates the ratchet to the left or right, causing the hexagonal bolt 1 to quickly and without disassembly flip the contact surface of the conductive block 10. This improves continuous operation and work efficiency.
