Description
Technical Field
[0001] The utility model relates to the technical field of metal processing, in particular to a wire cutting device. Background Art
[0002] In recent years, with the rapid development of the aerospace industry, orders for core components in aerospace and aviation have surged. Among them, the number of orders for small brackets has increased, which has increased the workload of wire cutting equipment in cutting blanks. Because when using wire cutting equipment, it is necessary to use molybdenum wire to move continuously under a high-voltage electric field to achieve cutting of the workpiece. To this end, it is necessary to use a conductive block to contact the molybdenum wire, so that the molybdenum wire generates a high-voltage electric field. However, this method will cause the conductive block to wear due to friction during the contact process with the molybdenum wire, that is, the conductive block will wear out grooves at the position where it contacts the molybdenum wire. After the grooves are generated on the surface of the conductive block, the molybdenum wire will be stuck in the groove when the equipment is running, resulting in wire breakage. At this time, the equipment needs to be paused, which affects the processing of parts and reduces production efficiency. In existing wire cutting equipment, since the molybdenum wire passes through the lower surface of the conductive block, the operator cannot observe the wear of the conductive block. In order to avoid wire breakage, the conductive block can only be replaced frequently. In view of this, there is an urgent need for a wire cutting equipment that can facilitate the operator to observe the wear of the conductive block in a timely manner and reduce the occurrence of wire breakage.

Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner, as would be apparent to one of ordinary skill in the art from this disclosure.
[0025] Below, with reference to the accompanying drawings, possible embodiments of the wire cutting device 10 in the present application are described exemplarily.
[0026] Figure 1 This is a schematic diagram of the structure of the wire cutting device 10 in this application. Figure 1 As shown, the wire cutting equipment 10 of the present application includes a frame 100, guide wheels 200, an electrode wire 300, and a conductive block 400. A plurality of guide wheels 200 are provided, each mounted on the frame 100. The electrode wire 300 is arranged around the guide wheels 200. The conductive block 400 is mounted on the frame 100, and the electrode wire 300 between two guide wheels abuts the upper surface of the conductive block 400. Thus, by abutting the upper surface of the conductive block 400 between the two guide wheels, the operator can conveniently observe the wear of the conductive block 400 from above, allowing for timely replacement of the conductive block 400 and reducing the occurrence of wire breakage. Furthermore, by abutting the upper surface of the conductive block 400 between the two guide wheels, the operator can adjust the position of the electrode wire 300 based on the position of the grooves worn on the conductive block 400, further preventing the electrode wire 300 from breaking due to the influence of the grooves.
[0027] In some embodiments, the electrode wire 300 is a molybdenum wire or other suitable materials.
[0028] In some embodiments, as Figure 1 As shown, the wire electrode 300 between the two guide wheels 200 is bent upward at the center to abut against the upper surface of the conductive block 400. This allows the existing wire-cutting equipment 10 to be modified so that the wire electrode 300 abuts against the upper surface of the conductive block 400, making it easier for operators to observe the wear status of the conductive block 400. This reduces equipment modification costs and facilitates operator operation.
[0029] In some embodiments, the conductive block 400 is mounted on the frame 100 via a first adjustment structure to adjust the angle and position of the conductive block 400 .
[0030] In some embodiments, the first adjustment structure includes a bolt, with the conductive block 400 being fixed to the frame 100 via the bolt. When the bolt is not tightened, the conductive block 400 can rotate about the bolt. Thus, when the wear on the upper surface of the conductive block 400 reaches a predetermined level, the bolt can be loosened to rotate the conductive block 400, thereby causing the surface of other portions of the conductive block 400 to abut against the wire electrode 300. This reduces the difficulty of operation for the operator.
[0031] In some embodiments, the first adjustment structure adjusts the distance between the conductive block 400 and the frame 100 by means of bolts, snap connections, etc. Thus, the operator can adjust the contact position between the electrode wire 300 and the upper surface of the conductive block 400, thereby improving the efficiency of the conductive block 400 and reducing the difficulty of operation for the operator.
[0032] In some embodiments, the frame 100 is provided with a relief portion, through which the electrode wire 300 passes between the two guide wheels 200. Thus, by providing the relief portion on the frame 100, the electrode wire 300 can be avoided when the middle portion of the electrode wire 300 bends upward, thereby ensuring the normal operation of the electrode wire 300.
[0033] In some embodiments, the frame 100 includes a base 110, a column 120, a first working arm 130, and a second working arm 140. The column 120 is disposed on the base 110, the first working arm 130 is disposed on the column 120, and the second working arm 140 is disposed on the column 120 and is located below the first working arm 130.
[0034] In some embodiments, the guide wheel 200 includes two main guide wheels 210 , which are respectively disposed on the first working arm 130 and the second working arm 140 .
[0035] In some embodiments, the first working arm 130 is provided with an adjusting head 131 that can move up and down, and a main guide wheel 210 is provided on the adjusting head 131 .
[0036] In some embodiments, the guide wheel 200 also includes two tensioning wheels 220. A second adjustment mechanism 150 is provided on the column 120. The two tensioning wheels 220 are provided on the second adjustment mechanism 150. The second adjustment mechanism 150 adjusts the distance between the two tensioning wheels 220 and the two main guide wheels 210.
[0037] In some embodiments, the second adjustment mechanism 150 includes a guide rail 151 and a mounting plate 152. The guide rail 151 extends in a direction close to / away from the main guide wheel 210, the mounting plate 152 is slidably connected to the guide rail 151, and the two tensioning wheels 220 are disposed on the mounting plate 152.
[0038] In some embodiments, the wire cutting device 10 further includes a wire storage drum 500 , in which the electrode wire 300 is stored. The electrode wire 300 extends from the wire storage drum 500 , passes around the guide wheel 200 , and then returns to the wire storage drum 500 .
[0039] In some embodiments, the wire storage drum 500 is arranged on the side of the two tensioning wheels 220 away from the two main guide wheels 210. The guide wheel 200 also includes two auxiliary wheels 230, which are arranged on the column 120, between the two tensioning wheels 220, and on the side of the two tensioning wheels 220 close to the two main guide wheels 210.
[0040] The above content has been used to exemplify possible embodiments of the wire cutting device 10 in the present application. Next, in conjunction with the accompanying drawings, the specific structure of the wire cutting device 10 in the present application will be described in detail in a specific embodiment.
[0041] like Figure 1 As shown, the wire cutting device 10 in this embodiment includes a frame 100, a guide wheel 200, an electrode wire 300, a conductive block 400, and a wire storage drum 500. The guide wheel 200, the electrode wire 300, the conductive block 400, and the wire storage drum 500 are mounted on the frame 100. Multiple guide wheels 200 are provided. The electrode wire 300 is stored in the wire storage drum 500. The electrode wire 300 extends from the wire storage drum 500, passes around the guide wheel 200, and then returns to the wire storage drum 500. The electrode wire 300 between the two guide wheels 200 abuts against the upper surface of the conductive block 400. The electrode wire 300 is a molybdenum wire. Abutting the conductive block 400 creates a high-voltage electric field, which drives the electrode wire 300 to continuously move, thereby achieving cutting of the workpiece.
[0042] like Figure 1 As shown, the frame 100 includes a base 110, a column 120, a first working arm 130, and a second working arm 140. The column 120 is vertically mounted on the base 110, while the first working arm 130 and the second working arm 140 are horizontally mounted on the column 120. The second working arm 140 is located below and parallel to the first working arm 130. An adjustment head 131 is vertically mounted at the end of the first working arm 130. The adjustment head 131 is threadedly connected to the first working arm 130 and can move up and down on the first working arm 130.
[0043] like Figure 1As shown, a second adjustment mechanism 150 is also provided on the column 120. The second adjustment mechanism 150 includes a guide rail 151 and a mounting plate 152. The guide rail 151 extends in the horizontal direction and is arranged parallel to the first working arm 130 and the second working arm 140. The mounting plate 152 is a rectangular plate-like component, which is arranged in a vertical state on the guide rail 151. The mounting plate 152 is slidably connected to the guide rail 151 so that the mounting plate 152 can slide along the guide rail 151. A fastening structure is also provided on the mounting plate 152. When the mounting plate 152 slides to a predetermined position, the mounting plate 152 can be fixed by the fastening structure. As a result, the tensioning wheel 220 described below can move horizontally with the mounting plate 152, so that it can approach / move away from the main guide wheel 210 described below.
[0044] like Figure 1 As shown, there are six guide wheels 200 located on the same plane. Based on their function and location, they can be divided into two main guide wheels 210, two tensioning wheels 220, and two auxiliary wheels 230. One of the two main guide wheels 210 is located on the adjustment head 131, and the other is located on the second working arm 140, directly below the main guide wheel 210 on the adjustment head 131. The two tensioning wheels 220 are mounted on the mounting plate 152, at the same height as the two main guide wheels 210, forming a rectangle with the two tensioning wheels 220 and the two main guide wheels 210. The two auxiliary wheels 230 are vertically mounted on the column 120, within the rectangle formed by the two tensioning wheels 220 and the two main guide wheels 210.
[0045] like Figure 1 As shown, the wire storage drum 500 is mounted on the frame 100, located between the two tensioning pulleys 220 and the two main drive pulleys 210. After the electrode wire 300 extends from the wire storage drum 500, it passes upward from below the auxiliary pulley 230, changes direction, passes upward from below the tensioning pulley 220, then passes downward from above the main drive pulley 210, passes downward from above the main drive pulley 210, and then passes downward from below the auxiliary pulley 230. The electrode wire 300 then extends to below the tensioning pulley 220, passes around the tensioning pulley 220, changes direction, passes below the auxiliary pulley 230, and returns to the wire storage drum 500.
[0046] like Figure 1As shown, the conductive block 400 is disposed on the second working arm 140, and the electrode wire 300 located between the tensioning wheel 220 and the main guide wheel 210 below abuts the upper surface of the conductive block 400, causing the electrode wire 300 to bend upward in the middle position. This allows operators to conveniently observe the wear of the conductive block 400 from above, allowing them to replace the conductive block 400 in a timely manner, thereby reducing the occurrence of wire breakage. In addition, by abutting the electrode wire 300 between the two guide wheels against the upper surface of the conductive block 400, operators can also adjust the position of the electrode wire 300 based on the position of the grooves worn on the conductive block 400, thereby further preventing the electrode wire 300 from breaking due to the influence of the grooves.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
