[0057] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] Please refer to Figures 1 to 8 The utility model provides a front and rear double-wire drum wire cutting device, comprising a support column 1, a front wire winding device 2, a rear wire winding device 3, a wire cutting wire 4, a storage table 5 and a wire cutting machine head 6;

[0059] The rear wire winding device 3 is installed on the rear side of the support column 1; the front wire winding device 2, the storage table 5 and the wire cutting machine head 6 are respectively installed on the front side of the support column 1; the front wire winding device 2 and the wire cutting machine head 6 are arranged side by side and located above the storage table 5;

[0060] The storage table 5 is used to place the workpiece to be cut; the wire cutting machine head 6 is used to cut the workpiece to be cut;

[0061] The support column 1 is provided with a guide arm 10, and the guide arm 10 passes through the storage table 5 forward; one end of the wire cutting wire 4 is fixed to the rear wire winding device 3, and the other end of the wire cutting wire 4 passes through the guide arm 10 and then passes through the wire cutting machine head 6 upward, and is fixed to the front wire winding device 2; the front wire winding device 2 and the rear wire winding device 3 are used to wind up or release the wire cutting wire 4, the rear wire winding device 3 winds up the wire cutting wire 4, and the front wire winding device 2 releases the wire cutting wire 4, or the front wire winding device 2 winds up the wire cutting wire 4, and the rear wire winding device 3 releases the wire cutting wire 4.

[0062] The front and rear double-wire drum wire cutting device is provided with a front wire winding device 2 and a rear wire winding device 3, and the purpose of wire release is achieved through the cooperation of the front wire winding device 2 and the rear wire winding device 3; the front wire winding device 2 and the rear wire winding device 3 are operated at a rotational speed, and when the rear wire winding device 3 reels the wire cutting wire 4 and the front wire winding device 2 releases the wire cutting wire 4, the reeling speed of the rear wire winding device 3 is greater than the releasing speed of the front wire winding device 2. On the contrary, when the front wire winding device 2 reels the wire cutting wire 4 and the rear wire winding device 3 releases the wire cutting wire 4, the reeling speed of the front wire winding device 2 is greater than the releasing speed of the rear wire winding device 3, thereby achieving a tensioning effect, replacing the tensioning structure of the existing wire cutting device, reducing the components of the wire cutting device, and saving production costs. When the cutting wire is installed for the first time, when a new wire cutting wire 4 needs to be inserted, the staff will wind the wire cutting wire 4 around the front wire winding device 2, and pass the movable end of the wire cutting wire 4 into the wire cutting machine head 6, then pass through the storage table 5, and enter the guide arm 10; through the turning of the guide arm 10, the movable end of the wire cutting wire 4 is fixed to the rear wire winding device 3.

[0063] When the wire cutting wire 4 is seriously damaged, the staff can first move the wire cutting wire 4 of that section to the area between the wire cutting machine head 6 and the guide arm 10; then, cut off the worn part of the wire cutting wire 4 to produce a new active end of the wire cutting wire head, and then release the wire cutting wire 4 through the front wire winding device 2; insert the active end of the wire cutting wire head into the guide arm 10, remove the cut wire cutting wire 4, and then wind the active end of the wire cutting wire head around the rear wire winding device 3. Conversely, the wire cutting wire 4 can also be released through the rear wire winding device 3, and the active end of the new wire cutting wire head can be wound around the front wire winding device 2, which is more convenient and simple to operate.

[0064] By adopting the above structure, the cutting segment of the wire cutting wire 4 can be automatically updated. The operation is simple. The staff does not need to wind the wire cutting wire 4 from the back side of the wire cutting device to the front side, and then from the wire cutting device to the back side. The complicated operation of replacing the wire cutting wire is simplified, the winding time is shortened, and the efficiency of replacing the wire cutting wire 4 is improved.

[0065] At the same time, since the total winding length of the wire cutting wire 4 is reduced, the length of the wire cutting wire 4 exposed to the outside released by the front wire winding device 2 or the rear wire winding device 3 is shortened, thereby solving the problem that when the wire drum of the front wire winding device 2 and the rear wire winding device 3 changes direction, the wire cutting wire 4 continues to move due to inertia, causing the wire cutting wire 4 to shake and produce reversing lines on the surface of the cut object. It is more stable and improves cutting accuracy.

[0066] In specific applications, the installation direction of the front winding device 2 can be adjusted according to actual conditions. It can be placed vertically or horizontally. Please refer to Figure 1 , Figure 1 The front wire winding device 2 in the embodiment is placed vertically.

[0067] Specifically, the front wire winding device 2 includes a front wire storage drum 21, a front wire storage drum mounting seat 22 and a front wire storage drum driving assembly 23;

[0070] The front wire storage drum 21 can rotate and move along the Z-axis direction under the drive of the front wire storage drum driving assembly 23, so that the wire cutting wire 4 can be automatically and neatly wound on the front wire storage drum 21, thereby improving the winding efficiency of the front wire storage drum 21.

[0071] Specifically, a connecting arm 11 extending forward is provided at the top of the support column 1, and a mounting plate 12 is provided at the front end of the connecting arm 11.

[0072] By adopting the above structure, the horizontal distance between the support column 1 and the wire cutting head 6 can be extended, so that the operating space below the wire cutting head 6 is larger, which is convenient for the wire cutting device to perform wire cutting on large workpieces to be processed.

[0073] The cutting wire drum 13 plays a guiding role, so that the cutting wire 4 can be wound around the front wire storage drum 21.

[0074] Specifically, the front wire storage drum driving assembly 23 includes a front wire storage drum rotating seat 231, a front wire storage drum sliding seat 232, a front wire storage drum driving member 233, a front transmission gear set 234, a front wire storage drum transmission screw rod 235, a front wire storage drum sliding block 236, a front wire storage drum guide rail 237 and a front guide rail seat 238;

When the front wire storage barrel driving member 233 drives the front wire storage barrel 21 to rotate, the first transmission gear, the second transmission gear and the third transmission gear are driven to rotate in sequence, thereby driving the front wire storage barrel transmission screw 235 to rotate; through the screw transmission structure of the front wire storage barrel transmission screw 235 and the front wire storage barrel sliding block 236, the front wire storage barrel sliding seat 232 is driven to move along the Z-axis direction.

[0081] The front wire storage drum guide rail 237 and the front guide rail seat 238 play the role of limiting guidance, so that the front wire storage drum sliding seat 232 moves along the Z-axis direction, avoiding the front wire storage drum sliding seat 232 from moving in other directions, and improving the stability of the front wire storage drum driving assembly 23.

[0106] The other end of the wire cutting wire 4 passes through the second conductive block 682 from the second threading nozzle 69 and passes through the gap between the second driving wheel 683 and the second driven wheel 684. After the wire cutting wire 4 is tangent to the second steering guide wheel 67, it is connected to the front wire winding device 2.

[0107] The connecting block 61 is fixed to the connecting arm 11. When the lifting head of the wire cutting machine needs to rise, the head driving device drives the guide rail 65 and the guide column 62 to move upward, so that the guide rail 65 is displaced upward relative to the slider 66; the guide column 62 drives the lifting plate 64 to move upward, so that the level of the lifting plate 64 is increased.

With the above structure, the distance between the first threading nozzle 106 and the second threading nozzle 69 can be reduced by the head driving device, which is convenient for the staff to perform the threading operation.

[0108] The second steering guide wheel 67 plays a role of tensioning and guiding, so that the wire cutting wire 4 is turned from the Z-axis direction to the X-axis direction, so that it can be wound on the front winding device 2.

[0109] The second driving assembly 68 plays the role of tensioning the wire cutting wire 4 and assisting the front winding device 2 in winding the wire cutting wire 4. The wire cutting wire 4 passes through the gap between the second driving wheel 683 and the second driven wheel 684, and the second driving motor 681 can drive the second driving wheel 683 to rotate. Through the friction between the second driving wheel 683 and the wire cutting wire 4, and between the wire cutting wire 4 and the second driven wheel 684, the wire cutting wire 4 is tensioned or driven to move toward the front winding device 2.

[0110] Furthermore, the machine head driving device includes a motor mounting plate 631, a fixing seat 632, a machine head motor 633, a driven gear 634, a screw rod 635 and a driving block 636;

[0112] When the head motor 633 rotates, the output end of the head motor 633 drives the driving gear to rotate, and the driven gear 634 and the screw rod 635 nut also rotate accordingly. Since the screw rod 635 is threadedly connected to the screw hole of the driving block 636, and the screw rod 635 is rotatably connected to the mounting plate 12, the mounting plate 12, the lifting rod and the head driving device move up and down relative to the guide column 62, thereby achieving the purpose of lifting. The above structure is simple and the transmission is stable.
