Description

Technical Field

[0001] This utility model relates to the field of chemical waste gas treatment equipment, and in particular to an automatic tungsten electrode cutting machine. Background Technology

[0002] Tungsten electrodes, due to the properties of tungsten, are well-suited for TIG welding and other similar applications. Adding rare earth oxides to metallic tungsten stimulates its electron work function, improving the welding performance of tungsten electrodes, resulting in better arc initiation, higher arc column stability, and lower electrode burn-off rate. Common rare earth additives include cerium oxide, lanthanum oxide, zirconium oxide, yttrium oxide, and thorium oxide.

[0003] During the production of tungsten electrodes, long tungsten electrode rods are cut into sections of specified dimensions using a cutting machine. Since tungsten electrode rods generally have a small diameter, several rods are often cut together to improve efficiency. However, existing tungsten electrode rod cutting machines rely on manual assistance to clamp the rods together before cutting. This manual assistance limits the precision of the cutting process, resulting in low efficiency and safety concerns. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an automatic tungsten electrode cutting machine that automatically clamps the tungsten electrode rod, automatically feeds it forward, and performs cutting.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic tungsten electrode cutting machine includes a base and an auxiliary feeding rack disposed on one side of the base. A clamping assembly is provided on the base, and a cutting machine body and a feeding assembly are fixed to the other side of the base. The clamping assembly clamps the tungsten electrode rod and moves it to the cutting machine body for cutting. The clamping assembly includes a first clamping group, a second clamping group, and a third clamping group arranged in parallel. A sliding mechanism is provided on the base between the first and third clamping groups. The second clamping group is fixed to the sliding mechanism. The first and third clamping groups have identical structures. The first clamping group includes a first clamping block and a second clamping block. The first clamping block is fixed to the base, and a first clamping cylinder is fixed to the base. The second clamping block is fixed to the output end of the first clamping cylinder. The second clamping group includes a third clamping block and a fourth clamping block. The third clamping block is fixed to the sliding mechanism, and a second clamping cylinder is fixed to the sliding mechanism. The fourth clamping block is fixed to the output end of the second clamping cylinder.

[0007] Further optimized, the first clamping block, the second clamping block, the third clamping block and the fourth clamping block are all provided with arc-shaped clamping grooves.

[0008] Further optimized, the first clamping block and the second clamping block, and the third clamping block and the fourth clamping block are provided with intermeshing clamping teeth.

[0009] Further optimized, the auxiliary feeding rack is provided with several V-shaped rollers, and the V-groove on the V-shaped roller is at the same height as the clamping groove.

[0010] In a further optimized manner, the sliding mechanism includes a lead screw, a sliding plate, a timing plate, a motor, and two slide rails. The two slide rails are fixed on the base, the sliding plate is slidably mounted on the slide rails, the timing plate is fixed to the bottom of the sliding plate, the lead screw passes through the timing plate and is rotatably connected to the base, the motor is fixed to the side wall of the base, and the output shaft of the motor is connected to one end of the lead screw.

[0011] In a further optimized configuration, the second clamping cylinder and the third clamping block are fixed to the slide plate.

[0012] Further optimized, a water supply nozzle is fixed on one side of the cutting machine body, and the water supply nozzle faces the tungsten electrode rod.

[0013] In a further optimized configuration, the feeding assembly includes a conveyor belt, the head of which is located below the cutting machine body.

[0014] Further optimized, a receiving box is provided at the bottom of the end of the conveyor belt. The receiving box is in the shape of an inverted trapezoid, and an inclined screen plate is provided inside the receiving box.

[0015] The beneficial effects of this utility model are:

[0016] This new type of machine can simultaneously clamp several tungsten electrode rods. The three clamping groups alternately clamp and move the tungsten electrode rods, automatically feeding them to the cutting machine body and completing the cutting automatically without manual intervention, resulting in high cutting efficiency.

[0017] This new type of clamping block features an arc-shaped clamping groove and interlocking clamping teeth, resulting in a tighter and more stable clamping of multiple tungsten electrode rods and higher cutting precision. A conveyor belt at the bottom of the cutting machine automatically collects the cut tungsten electrodes into a receiving box, making it convenient to use.

[0018] In this new type of device, the clamping groove of one side of the clamping block remains stationary in the center, while the clamping block on the other side moves to clamp the electrode. During cutting, the auxiliary feeding rack feeds the electrode, one end of which passes through the first clamping group. Then, the second clamping group clamps the tungsten electrode and moves it to the third clamping group. The first and third clamping groups clamp the tungsten electrode, and the cutting machine cuts it. First, the tungsten electrode is cut evenly, and at the same time, the second clamping group resets. The second clamping group clamps the electrode, and the first and third clamping groups release. The second clamping group moves the tungsten electrode to the required cutting length. The first and third clamping groups clamp the electrode again for the actual cutting. Then, the first and third clamping groups release, and the second clamping group moves the tungsten electrode. Cutting and moving are performed alternately in sequence, automatically completing the cutting process. Attached Figure Description
