At present, manual cutting has problems of low efficiency and poor cutting quality. The patent document with the publication number of CN219852454U in the prior art provides a processing device for thick-walled tantalum-tungsten tubes. Through the setting of the auxiliary cutting unit, thick-walled tantalum-tungsten tubes with different apertures can be stably placed on the sliding seat, and efficient cutting work for thick-walled tantalum-tungsten tubes with different apertures can be realized. Through the setting of the auxiliary cutting unit, it replaces the existing manual auxiliary cutting work, can realize standard circular cutting, improve cutting accuracy, reduce material waste, and has high practicability.

[0004] Although the processing device can clamp tantalum-tungsten tubes with different sizes and can perform automatic cutting, the clamping operation method for tantalum-tungsten tubes in the early stage is relatively cumbersome, which is rather inconvenient when facing multiple tubes to be cut, affecting the production and processing efficiency. Therefore, there is an urgent need for an auxiliary tooling for cutting tantalum materials to solve the above problems. Summary of the Utility Model

[0026] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings in the specification.

[0027] Embodiment 1

[0028] Referring to Figures 1-5 , as the first embodiment of the present utility model, an auxiliary tooling for the cutting of tantalum materials is provided. This auxiliary tooling for the cutting of tantalum materials includes a base 1, a lifting seat 2 is vertically slidably connected to the base 1, a steering cutting unit 3 is installed on the lifting seat 2, and a clamping mechanism 4 is fixedly provided at the bottom of the base 1. The clamping mechanism 4 is used for clamping and limiting the tantalum material tube.

[0029] In the above technical solution, the base 1 is composed of two vertically arranged bottom plates. The lifting seat 2 is slidably connected to the limiting rod on the vertically arranged bottom plate. The tantalum tube can be placed in the clamping mechanism 4. While the clamping mechanism 4 clamps the tantalum tube, the tantalum tube can rotate within the clamping mechanism 4. After the lifting seat 2 descends and drives the turning and cutting unit 3 to contact the tantalum tube, it can drive the tantalum tube to rotate and perform a circular cut on it.

[0030] The clamping mechanism 4 includes a cross bar 401. Arc-shaped plates 402 are fixedly connected to both ends of the cross bar 401. An arc-shaped plate 403 is slidably connected within the arc-shaped plate 402. A plurality of limiting rollers 404 are hinged between the arc-shaped plate 402 and the arc-shaped plate 403.

[0031] In the above technical solution, both the arc-shaped plate 402 and the arc-shaped plate 403 are in the shape of a superior arc. The inner cavity of the arc-shaped plate 403 is used to place the tantalum tube. The axial direction of the limiting roller 404 is the same as the axial direction of the arc-shaped plate 403. When the cross bar 401 drives the arc-shaped plate 402 to rotate, the plurality of limiting rollers 404 contract synchronously until they abut against the outer wall of the tantalum tube, completing the limitation of the tantalum tube and at the same time making the axis of the tantalum tube coincide with the axis of the arc-shaped plate 403.

[0032] An electric push rod 201 is fixedly connected to the lifting seat 2. One end of the electric push rod 201 is fixedly connected to the base 1. When the electric push rod 201 expands and contracts, it drives the lifting seat 2 to move up and down on the base 1, realizing the movement of driving the turning and cutting unit 3.

[0033] The turning and cutting unit 3 includes a cutting motor 301 and a turning motor 303 fixedly installed on the lifting seat 2. A cutting blade 302 is fixedly connected to the output end of the cutting motor 301. A turning wheel 304 is fixedly connected to the output end of the turning motor 303.

[0034] In the above technical solution, the bottom height of the cutting blade 302 is lower than the bottom height of the turning wheel 304. When the turning wheel 304 descends to abut against the outer wall of the tantalum tube, the cutting blade 302 can perform a penetrating cut on the tantalum tube. The turning motor 303 drives the turning wheel 304 to rotate, the turning wheel 304 drives the tantalum tube to rotate, and at the same time the cutting motor 301 drives the cutting blade 302 to rotate to perform a circular cut on the tantalum tube.

[0035] The limiting roller 404 is connected to a connecting seat 405. Link rods 406 are hinged to both sides of the connecting seat 405. One link rod 406 is hinged to the arc-shaped plate 402, and the other link rod 406 passes through the arc-shaped plate 402 and is hinged to the arc-shaped plate 403. Refer to Figure 3 、 Figure 4 , when the arc-shaped plate 402 rotates clockwise, the two link rods 406 drive the connecting seat 405 to move, causing the limiting roller 404 to move towards the center of the arc-shaped plate 403.

[0036] A U-shaped member 407 is slidably connected to the connecting seat 405. The U-shaped member 407 is rotatably connected to the limiting roller 404, and a first spring 408 is elastically connected between the U-shaped member 407 and the connecting seat 405. With the arrangement of the first spring 408, the limiting roller 404 is elastically abutted against the outer wall of the tantalum tube, which can avoid clamping deformation of the tantalum tube caused by excessive pressure.

[0037] The clamping mechanism 4 further includes a U-shaped rod 409 slidably connected to the base 1. A second spring 410 is elastically connected between the end of the U-shaped rod 409 and the base 1, and the U-shaped rod 409 is in clamping engagement with an arc-shaped rack 411 fixedly provided on the first arc-shaped plate 402.

[0038] In the above technical solution, the tooth cross-section of the arc-shaped rack 411 is in a right-angled triangle structure. When the first arc-shaped plate 402 rotates clockwise, the inclined surface of the tooth of the arc-shaped rack 411 contacts the U-shaped rod 409, causing the U-shaped rod 409 to move downward automatically to make way. When the first arc-shaped plate 402 stops rotating, the second spring 410 drives the U-shaped rod 409 to engage with the arc-shaped rack 411 to prevent the first arc-shaped plate 402 from rotating in the reverse direction.

[0039] During use, the tantalum tube is placed therein through the notch of the second arc-shaped plate 403. Subsequently, the cross bar 401 is driven to move downward. The first arc-shaped plate 402 rotates clockwise, causing the outer ends of the two connecting rods 406 to contract, driving the limiting roller 404 to elastically contact the outer wall of the tantalum tube, and making the axis of the tantalum tube coincide with the axis of the second arc-shaped plate 403. Subsequently, the electric push rod 201 drives the lifting seat 2 to descend, the cutting motor 301 drives the cutting blade 302 to rotate, the steering motor 303 drives the steering wheel 304 to rotate. When the steering wheel 304 abuts against the outer wall of the tantalum tube, it drives the tantalum tube to rotate, and at the same time, the cutting blade 302 performs a circular cutting on the tantalum tube.

[0040] Embodiment 2

[0041] Referring to Figure 3 , this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a third spring 412 is elastically connected between the cross bar 401 and the second arc-shaped plate 403.

[0042] In the above technical solution, when the cross bar 401 drives the first arc-shaped plate 402 to rotate and the limiting roller 404 clamps the tantalum tube, the third spring 412 is stretched under force. When the U-shaped rod 409 is pressed downward to cancel the limit on the first arc-shaped plate 402, the third spring 412 contracts and can drive the first arc-shaped plate 402 to rotate reversely and reset automatically, so that the limiting roller 404 cancels the clamping limit on the tantalum tube.

[0043] The remaining structures are the same as those in Embodiment 1.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
