Technical Field
[0001] The utility model relates to the technical field of slow-moving wire cutting machines, in particular to a wire roll replacement mechanism of a slow-moving wire cutting machine. Background Art
[0002] Wire cutting is a type of electric spark wire cutting. Wire cutting uses a continuously moving thin metal wire as an electrode to perform pulse spark discharge to erode metal and cut the workpiece into shape. It is mainly used to process various complex and precise small workpieces.
[0003] At present, after the existing slow-feeding wire cutting machine has been used for a period of time, the metal wire will show a certain degree of wear and tear. Therefore, the staff is required to remove the wire roll from the wire storage drum for replacement in time. The existing wire storage drum is fixed. If the old wire roll needs to be removed, the staff is required to use scissors to cut the wire roll from the wire storage drum. Since the wire roll is tightly wound on the wire storage drum, the staff is required to repeat the wire cutting operation many times. The whole replacement process is inconvenient. For this reason, we propose a wire roll replacement mechanism for a slow-feeding wire cutting machine to solve the above problem. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-4 A wire roll replacement mechanism for a slow-moving wire cutting machine includes a bottom plate 1, a fixed plate 2 is connected to the top of the left side of the bottom plate 1, and a motor 3 is installed on the side of the fixed plate 2. The rotation principle of the motor 3 is the existing technology, which can drive the continuous rotation of the wire drum 4, so as to realize the winding operation of the wire roll. The output end of the motor 3 passes through the inner wall of the fixed plate 2 and is connected to the wire drum 4, and a movable plate 5 is provided on the right side of the wire drum 4. Bolts are inserted on the upper side of the wire drum 4, so as to realize the fixing operation of the metal wire end. The bottom end of the movable plate 5 is connected to a linkage plate 11 near the fixed plate 2, and the bottom end of the linkage plate 11 is symmetrically connected to a slider 12. The bottom plate 1 is provided with a The slider 12 is adapted to the slideway, and the slider 12 and the slideway are T-shaped structures. The mutual cooperation between the slider 12 and the slideway can ensure the stability of the linkage plate 11 during movement. A connecting plate 6 is connected to the right side of the bottom end of the movable plate 5, and a limit rod 7 is symmetrically inserted inside the connecting plate 6. The top of the limit rod 7 is connected through a pulling plate 8. A positioning groove adapted to the limit rod 7 is opened inside the bottom plate 1. Through the mutual cooperation between the limit rod 7 and the pulling plate 8, it is convenient for the staff to release the restriction on the movable plate 5, so that it is convenient for the staff to drive the movable plate 5 and the wire reel 4 away from each other, so as to facilitate the staff to subsequently remove the old wire wrapped on the wire reel 4.
[0023] Further, see Figure 1 and Figure 4 It can be seen that a handle 10 is connected to the top of the movable plate 5, and a rubber sleeve is glued to the outside of the handle 10. The setting of the handle 10 can facilitate the staff to push the handle 10 to the right, and the setting of the rubber sleeve can prevent the staff from slipping during the pulling process.
[0024] Further, see Figure 4 It can be known that a spring 9 is symmetrically sleeved on the lower side of the pulling plate 8, and the other end of the spring 9 is fixedly connected to the connecting plate 6. The spring 9 is sleeved on the outside of the limiting rod 7. Through the connection of the spring 9, the tightness of the limiting rod 7 during the process of being engaged in the bottom plate 1 can be effectively facilitated.
[0025] Further, see Figure 2 It can be known that a connecting ring 15 is connected to the inner side of the movable plate 5, and an annular groove matched with the connecting ring 15 is opened at the right end of the wire reel 4. When in use, the connecting ring 15 connected to the inner side of the movable plate 5 can be snapped into the annular groove opened inside the wire reel 4. Through the mutual cooperation between the connecting ring 15 and the annular groove, the stability of the wire reel 4 during rotation can be effectively guaranteed.
[0026] Further, see Figure 2 It can be seen that grooves are evenly opened inside the connecting ring 15, and balls 16 are installed inside the grooves. The mutual cooperation between the grooves and the balls 16 can effectively prevent the connecting ring 15 and the annular friction from being damaged, so as to further ensure the smoothness of the rotation of the wire tube 4.
[0027] Further, see Figure 1 It can be known that a clamping plate 13 is connected to the left top end of the linkage plate 11, and a hole is opened inside the clamping plate 13, and the inner diameter of the hole is larger than the outer diameter of the wire reel 4. Since the inner diameter of the hole inside the clamping plate 13 is larger, the normal rotation of the wire reel 4 can be guaranteed, and the bolt of the wire reel 4 can be passed through to realize the pushing operation of the wire reel.
[0028] Further, see Figure 1 and Figure 3 It can be seen that the outer side of the clamping plate 13 is symmetrically connected with a pushing block 14, and the pushing block 14 is set as an L-shaped structure. The side of the pushing block 14 close to each other abuts against the outer wall of the wire tube 4. The pushing block 14 set by the L-shaped structure can further push the wire roll on the wire tube 4.
[0029] Working principle: When the utility model is used, the staff can first install the device at a suitable position on the slow-moving wire cutting machine, and then use a screwdriver to twist the bolt on the wire drum 4 upwards, and then the wire end of the metal wire can be wound around the bolt, and the bolt is twisted in the opposite direction again by the bolt cutter to fix the wire end. After the fixation is completed, the staff can start the motor 3, so that the metal wire can be wound around the periphery of the wire drum 4, and the other wire end of the metal wire can be wound around the wire drum of the cutting machine. After the winding is completed, the staff uses the metal wire wound on the wire drum 4 to perform cutting operations;
[0030] When it is necessary to replace the wire roll on the wire drum 4, the staff can first lift the pulling plate 8, so that the two groups of limit rods 7 connected thereto are forced to move upward at the same time, so that the two groups of limit rods 7 are pulled out from the positioning grooves opened inside the bottom plate 1, thereby contacting the limit of the movable plate 5, and then the staff can manually pull the handle 10, thereby driving the movable plate 5 to be pushed right as a whole. At this time, the slider 12 connected to the bottom end of the linkage plate 11 is forced to slide along the inner wall of the slideway, so that the movable plate 5 and the wire drum 4 are separated, and the linkage plate 11 is on the right. During the movement, the card plate 13 is simultaneously forced to move rightward, and with the help of four sets of pushing blocks 14 connected to the side of the card plate 13, the wire roll on the wire drum 4 can be pushed out, so as to further improve the convenience of the staff in taking out the wire roll. After the removal is completed, the staff can push the moving plate 5 to the left, and cooperate with the setting of the limiting rod 7 to reset it, and then the staff can fix the end of the new wire on the bolt of the wire drum 4, and drive it through the motor 3 to wind the metal wire around the periphery of the wire drum 4 for subsequent cutting. The above is the entire working principle of the utility model.

As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
