[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] This utility model provides an automatic tungsten electrode cutting machine, including a work frame 1. A slide rail 101 is fixedly connected to the work frame 1. A cutting motor base 102 is slidably mounted on the slide rail 101. A cutting motor 103 is mounted on the cutting motor base 102. A cutting blade 104 is rotatably connected to the cutting motor 103 via an assembly. A left support cylinder 2 is located below the cutting blade 104. A left moving cylinder 201 is located to the left of the left support cylinder 2. A left moving clamping auxiliary cylinder 202 is located to the left of the left moving cylinder 201. Both the left support cylinder 2 and the left moving cylinder 201 are driven by cylinders to drive the corresponding clamping structures to complete the operation. In operation, a carrier plate 203 is installed below the combined structure of the left moving cylinder 201 and the left moving clamping auxiliary cylinder 202. A left moving lead screw 3 passes through the carrier plate 203. A support 301 that can slide up and down is installed on the work frame 1. The left moving lead screw 3 is rotatably connected to the support 301. A left moving motor 302 is installed at the left end of the support 301. A limit plate 4 is also installed on the carrier plate 203. The left support cylinder 2 and the left moving cylinder 201 are symmetrically distributed on both sides of the limit plate 4. Both the left support cylinder 2 and the left moving cylinder 201 are driven and controlled by a PLC program. The left side of the left moving clamping auxiliary cylinder 202 is located at the left moving position. A feeding ramp 5 is provided below the lead screw 3. Multiple sets of material support rollers 501 are arranged within the feeding ramp 5. A feeding lever 502 is slidably disposed between adjacent material support rollers. A lead screw support roller 303 is mounted on the work frame 1 below the bracket 301. The lead screw support roller 303 can slide up and down within the work frame 1. Guide rails 6 are symmetrically mounted on the work frame 1 to the right of the left support cylinder 2. A series of auxiliary clamping cylinders 601, 602, 603, 604, and 605 are slidably arranged on the guide rails 6 from left to right. The auxiliary cylinders 605 and 606, as well as the cylinder-clamp combination structure, are symmetrically distributed on the guide rail 6. The auxiliary cylinders 601 and 602 are mounted on the same sliding block, as are the auxiliary cylinders 603 and 604. The auxiliary cylinders 605 and 606 are also mounted on the same sliding block. All of these cylinders are driven and controlled by a PLC program, facilitating overall feeding and limiting operations.

[0021] In actual use, the tungsten electrode multiple-length automatic cutting machine is used as an auxiliary automatic cutting machine for finished tungsten electrodes. It cuts long tungsten rods into 3-meter, 2-meter, or several different lengths. The cut tungsten rods are then placed on the automatic cutting machine and cut into finished tungsten electrodes. The worker pre-calculates the required number of cuts, inputting parameters such as distance, number of cuts, and speed onto the touchscreen. The worker places a bundle of tungsten rods in the center of the clamp, aligning the rod ends with the limit plate 4 as a reference, and presses the left moving clamp manual button. The left moving clamp then clamps the tungsten rods. The rod, the left support front clamp cylinder extends forward, the left support auxiliary cylinder moves the clamps forward but does not clamp the tungsten rod. Press start, the cutting motor 103 starts and drives the cutting disc 104 to rotate at high speed. The No. 1 clamp, No. 2 clamp, and No. 3 clamp auxiliary cylinders 605 move, each moving the corresponding clamping structure forward. After 0.4 seconds, the left moving clamping structure moves to the left to the preset distance under the drive of the left moving motor 302 and the left moving lead screw 3. During the leftward movement, the lead screw support roller 303 and the material support roller 501 rise in sequence to support the lead screw and tungsten rod, and the tungsten material moves into place. Then, the cylinders of the left support clamp, clamp 1, clamp 2, and clamp 3, which drive the clamping body, simultaneously clamp the tungsten rod. The cutting blade 104 cuts at a uniform speed under the drive of the drive assembly. After cutting to the set distance, it returns to the cutting waiting height. The left support clamp is released under the drive of the corresponding cylinder, and the left moving clamp moves to the left a set distance (left discharge distance) under the drive of the corresponding cylinder. The left moving clamp is released, the material support roller descends, and the cut tungsten rod is placed on the unloading platform. The unloading plate moves the cut tungsten material towards the slope, and the tungsten rod moves along the slope. The material slides down the slope and falls into the material tray. At the same time, the left moving clamp returns to its original position. During the return, the lead screw support roller 303 falls back in sequence, the feeding plate returns to its original position, clamps 1 and 3 loosen, and clamp 2 clamps the tungsten rod. Driven by the relevant drive components, it moves to the left to the set distance. The left moving clamp clamps the tungsten rod, and clamps 1 and 2 clamp (to prevent the tungsten material from being carried back by friction when clamp 2 returns to the origin). The feeding clamp 2 loosens and returns to the origin position. Clamps 1 and 2 loosen, and the left moving clamp moves to the left to the set distance. The above sequence is repeated until the tungsten material is cut to the set number of cuts. By setting a limiting auxiliary feeding device for tungsten rod cutting on the work frame 1, the tungsten rods are fed one by one to the bottom of the cutting blade 104, and then cut one by one to complete the cutting work. The tungsten rods are then fed to the unloading ramp 5, and the relevant drive auxiliary components unload the cut tungsten rods. Compared with the conventional method of manual measurement and cutting by the staff, the technical solution adopted by this utility model can realize the automated processing of tungsten rod cutting. The overall structure is compact, the space layout is reasonable, and it is easy for the staff to install and maintain.

[0022] Example 1

[0023] like Figure 1-3As shown, the sliding block is disposed between adjacent guide rails 6, and a limit frame 7 is provided on the work frame 1 at the position between the guide rails 6. A drive screw 701 is inserted through the limit frame 7. The sliding block is threadedly connected to the drive screw 701. A drive motor is installed at the right end of the drive screw 701, and the rotation of the drive screw 701 is driven by the drive motor.

[0024] The effect achieved by the entire embodiment 1 is that, in use, the drive motor drives the drive screw 701 to rotate. Since the sliding block and the drive screw 701 are connected by threads, they can slide left and right along the direction of the drive screw 701 during actual operation. Working Principle: The worker places a bundle of tungsten rods in the middle of the clamp, aligning the rod heads with the limiting plate as a reference. Pressing the manual button for the left moving clamp activates, clamping the tungsten rods. The left support front clamp cylinder extends forward, and the left support auxiliary cylinder pushes the clamps forward without clamping the tungsten rods. Pressing the start button activates the cutting motor, driving the cutting blade to rotate at high speed. The auxiliary cylinders of clamps 1, 2, and 3 all push forward their corresponding clamping structures. After a 0.4-second pause, the left moving clamping structure, driven by the left moving motor and the left moving lead screw, moves to the left to the pre-set distance. During this leftward movement, the lead screw support roller and the material support roller rise sequentially, supporting the lead screw and tungsten rods. Once the tungsten material is in place, the cylinders of the left support clamp, clamps 1, 2, and 3 simultaneously push forward to clamp the tungsten rods. The cutting blade, driven by the drive assembly, cuts at a uniform speed. After cutting to the set distance, it returns to the cutting position. Waiting for the desired height, the left support clamp is released under the corresponding cylinder drive, and the left moving clamp moves to the left a set distance (left discharge distance) under the corresponding cylinder drive. The left moving clamp is released, the material support roller descends, and the cut tungsten rod is placed on the unloading platform. The unloading plate moves the cut tungsten material towards the slope, and the tungsten rod slides down the slope and falls into the material tray. At the same time, the left moving clamp returns to its original position. When returning to its original position, the lead screw support roller falls back in sequence, the unloading plate returns to its original position, clamps 1 and 3 are released, and clamp 2 clamps the tungsten rod. Driven by the relevant drive components, it moves to the left to the set distance. The left moving clamp clamps the tungsten rod, and clamps 1 and 2 clamp (to prevent the tungsten material from being carried back due to friction when clamp 2 returns to the origin). The feeding clamp 2 is released and returns to the origin position. Clamps 1 and 2 are released, and the left moving clamp moves to the left to the set distance. The above sequence is repeated until the tungsten material is cut to the set number of cuts.
