Background Art
[0002] Silicon carbon rod is a non-metallic high-temperature electric heating element, mainly made of high-purity green hexagonal silicon carbide, sintered by high-temperature siliconization recrystallization at 2200℃. It is usually rod-shaped or tubular in shape. It can be used at a normal temperature of 1450℃ in an oxidizing atmosphere and can be used continuously for up to 2000 hours. It is widely used in the field of hot surface igniters.
[0003] As shown in the attached figure of the instruction manual Figure 1 As shown in the figure, in order to reduce thermal stress concentration and improve the thermal shock resistance of silicon carbon rods, double helix textures are usually engraved on the surface of silicon carbon rods. Traditional silicon carbon rods are generally formed with double helix textures by engraving machines, but engraving machines are expensive to purchase and complex to process. In addition, the material of the silicon carbon rod itself is fragile, and the breakage rate of the silicon carbon rod is high during the engraving process.
[0004] Some spiral silicon carbon rods are realized by bending a straight rod into a spiral shape, such as the Chinese patent with patent application number 201320628848X, which is introduced in the specification: the rod corresponding to the heating section is provided with two spiral grooves respectively connected to the two dividing grooves, and the two spiral grooves are arranged in a double helix form and penetrate the tube wall along the radial direction of the rod body so that the corresponding tube wall forms a spiral belt with a double helix structure, and the ends of the two spiral grooves away from the dividing grooves are terminated on the tube wall of the heating section so that the two spiral belts are connected as a whole, and at the same time, the two spiral belts are mutually conductive at this end of the rod body. However, this kind of production process is complicated and difficult to achieve. Utility Model Content

[0028] Example 1
[0029] As shown in the attached figure of the instruction manual Figures 2 to 5 As shown, a cutting and feeding device for double-helix texture molding of silicon carbon rods includes a module bottom plate 1 that plays a supporting role, a slide rail 11 is fixedly provided on the module bottom plate 1, and two sliding cutting mechanism assemblies 1 3 and 2 4 are slidably provided on the slide rail 11. The sliding cutting mechanism assembly 1 3 and the sliding cutting mechanism assembly 2 4 adopt the same structural design; specifically, the sliding cutting mechanism assembly 1 3 includes a nut seat 1 31 threadedly connected to the positive thread 51 of the lead screw 5, and a cutting blade 1 33 driven by a small motor 1 32 is fixedly provided on the nut seat 1 31; the sliding cutting mechanism assembly 2 4 includes a nut seat 2 41 threadedly connected to the reverse thread 52 of the lead screw 5, and a cutting blade 2 43 driven by a small motor 2 42 is fixedly provided on the nut seat 2 41; one end of the lead screw 5 is connected to the lead screw support seat 6 bearing, and the other end of the lead screw 5 is connected to the drive motor 7 in a transmission manner. The lead screw 5 is divided by the middle section, with a positive thread 51 on one side and a reverse thread 52 on the other side. The positive and reverse thread designs enable the object threadedly connected thereto to perform a relatively close or distant linear motion when the lead screw 5 rotates.
[0030] The specific working principle of this embodiment is as follows: under the action of the drive motor 7, the lead screw 5 rotates, and the nut seat 1 31 and the nut seat 2 41 threadedly connected to the lead screw 5 make a relatively close linear operation, so that the cutting blade 1 33 and the cutting blade 2 43 make a relatively close linear motion, and under the action of the small motor 1 32 and the small motor 2 42, the cutting blade 1 33 and the cutting blade 2 43 rotate continuously. When the cutting blade 1 33 and the cutting blade 2 43 reach their respective texture cutting starting points, the drive motor 7 stops moving. At this time, the silicon carbon rod 2 will rotate and move vertically upward slowly under the action of external force. The silicon carbon rod 2, the cutting blade 1 33, and the cutting blade 2 43 cooperate with each other to form the double helical texture on the silicon carbon rod 2. After the processing is completed, the drive motor 7 drives the lead screw 5 to rotate in the opposite direction, and the cutting blade 1 33 and the cutting blade 2 43 make a relatively far linear motion.
[0031] This embodiment has a simple and ingenious structure, stable and reliable operation, can use the same drive unit to achieve bidirectional feeding of the cutting blade, is economical and environmentally friendly, has precise synchronous action, and has high double helix texture cutting accuracy;
[0032] This embodiment is convenient to use and easy to implement, and greatly reduces the processing difficulty of double-helix texture forming of silicon carbon rods.

The sliding cutting mechanism assembly 1 3 and the sliding cutting mechanism assembly 2 4 adopt the same structural design. Specifically, the sliding cutting mechanism assembly 1 3 includes a nut seat 1 31 that is threadedly connected to the positive thread 51 of the lead screw 5, and a cutting blade 1 33 driven by a small motor 1 32 is fixedly provided on the nut seat 1 31; the sliding cutting mechanism assembly 2 4 includes a nut seat 2 41 that is threadedly connected to the reverse thread 52 of the lead screw 5, and a cutting blade 2 43 driven by a small motor 2 42 is fixedly provided on the nut seat 2 41; one end of the lead screw 5 is connected to the bearing of the lead screw support seat 6, and the other end of the lead screw 5 is connected to the driving motor 7 in a transmission manner. The lead screw 5 is divided by the middle section, with a positive thread 51 on one side and a reverse thread 52 on the other side. The positive and reverse thread settings enable the object threadedly connected to the lead screw 5 to perform a relatively close or distant linear motion when the lead screw 5 rotates.
[0036] In this embodiment, the cutting blade 1 33 and the cutting blade 2 43 are arranged in an inclined direction. Specifically, an L-shaped support plate 1 34 is fixedly mounted on the nut seat 1 31, and the vertical plate of the L-shaped support plate 1 34 is fixedly connected to the cutting blade support seat 1 35, and the cutting blade 1 33 on the cutting blade support seat 1 35 is inclined toward one end of the L-shaped support plate 1 34; the cutting blade support seat 1 35 is inclined relative to the L-shaped support plate 1 34, so that the cutting blade 1 33 is inclined. An L-shaped support plate 2 44 is fixedly mounted on the nut seat 2 41, and a cutting blade support seat 2 45 is fixed on the vertical plate of the L-shaped support plate 2 44, and a cutting blade 2 43 is fixed on the cutting blade support seat 2 45, which is inclined in the opposite direction to the cutting blade 1 33, and the inclination angle of the cutting blade 2 43 is equal to that of the cutting blade 1 33; the cutting blade support seat 2 45 is inclined relative to the L-shaped support plate 2 44, so that the small motor 1 32 is inclined. The two cutting blades are arranged in an inclined direction. This design ensures that during the vertical upward movement of the silicon carbon rod, the force exerted by the two cutting blades on the silicon carbon rod can always remain consistent with the tangent direction of the spiral motion trajectory, effectively reducing the destructive stress acting on the silicon carbon rod, greatly reducing the breakage rate of the silicon carbon rod, thereby effectively reducing production costs.

[0039] The module base plate 1 of this embodiment is fixed on the workbench 92 via the column 91. There are various ways to realize the small motor driving the cutting blade. From the perspective of cost and stable operation, the small motor 1 32 and the small motor 2 42 of this embodiment are both connected to the blade connecting shaft of their respective cutting blades by a transmission method of a synchronous belt and a synchronous wheel. That is, the small motor drives the cutting blade to rotate through the synchronous wheel, the synchronous belt, and the blade connecting shaft. The structural design is compact and flexible.
