Description

Technical Field

[0001] The invention relates to the technical field of graphite welding, in particular to an artificial graphite welding preparation device. Background Art

[0002] The length of artificial graphite is generally within 2 meters. Due to the limitations of equipment and process, the manufacture of artificial graphite exceeding 2 meters or even longer has the disadvantages of high production cost, high defective rate of finished products and low product performance. Therefore, when artificial graphite of longer length is needed, welding between artificial graphites is currently used to fix the two of them together. Before welding, the graphene particle welding material needs to be pre-embedded in the welding gap, and the welding material is manually pressed by tools to remove the air in the graphene particles as much as possible. However, in the above-mentioned step of pressing the welding material, there is still a problem that the welding material is not in tight contact with the welding contact surface, and there is still a small amount of air in the graphene particles. Manual pressing is time-consuming and labor-intensive. Therefore, in view of the above-mentioned problems, the present invention designs an artificial graphite welding preparation device. Summary of the invention

[0003] The design purpose of the present invention is to provide an artificial graphite welding preparation device, wherein a limiting component limits and fixes the artificial graphite to be welded, and a pressing component comprises a pressing block a and a pressing block b, and a driving component drives the pressing blocks a and b to perform reciprocating pressing on the outer circle welding material and the inner circle welding material respectively by rotation, and the reciprocating pressing by the pressing blocks a and b makes the welding material fit more closely with the welding contact surface, and the reciprocating pressing by the pressing blocks a and b on the outer circle and the inner circle of the welding material can make the air in the welding material be removed more thoroughly, and at the same time, the disadvantage of long-term manual pressure to remove the air is eliminated.

[0013] Beneficial effects of the present invention:

[0014] 1. The limiting assembly of the present invention limits and fixes the artificial graphite to be welded, and the pressing assembly includes a pressing block a and a pressing block b. The driving assembly drives the pressing blocks a and b to perform reciprocating pressing on the outer circle welding material and the inner circle welding material respectively by rotation. The reciprocating pressing operation enables the welding material to fit more closely with the welding contact surface, and the reciprocating and alternating pressing of the outer circle and the inner circle of the welding material by the pressing blocks a and the pressing blocks b can more thoroughly remove the air in the welding material, which is beneficial to improving the subsequent welding quality, and also saves the disadvantage of long-term manual pressure to remove the air.

[0015] 2. The welding material of the present invention is pre-buried on the welding contact surface, and the pressing block a and the pressing block b are driven by the driving assembly to perform alternate reciprocating pressing. The pressing block a first presses the outer ring of the welding material (such as the attached Figure 8As shown in the figure, the air inside the outer ring of the welding material is discharged to the outside and through the vent on the top pressure block a under the top pressure, and then the top pressure block b presses the inner ring of the welding material (as shown in the figure). Figure 7 As shown in the figure, a small amount of air in the inner circle of the welding material will be transferred to the outer circle of the welding material, and part of the air will be discharged through the vent on the top pressure block b. By repeatedly alternating the top pressure, the air in the welding material on the entire contact surface can be completely eliminated. If a single top pressure block is used for repeated top pressure, some air will always remain in the welding material and cannot be discharged smoothly.

[0016] 3. The present invention uses a pressing assembly to reciprocately press the welding material on the graphite welding contact surface, which can ensure that the thickness of the welding material on the contact surface is uniform, and the welding material fits more tightly at various parts of the contact surface, ensuring the stability of the strength of various parts on the subsequent welding section and improving the stability of artificial graphite welding.

[0017] In summary, the artificial graphite welding preparation device has the advantages of ingenious design, simple structure, high efficiency and stability in use, and is particularly suitable for the field of graphite welding technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0028] Embodiment 1

[0029] like Figures 1 to 8 As shown, an embodiment of the present invention provides an artificial graphite welding preparation device, including a bearing platform 1, a limiting component 2 is arranged on the bearing platform 1, the limiting component 2 is used to fix and limit the side section of the artificial graphite 101, a top pressing component 3 is arranged between the artificial graphite 101, the top pressing component 3 includes a top pressing block a301 and a top pressing block b302, the top pressing block a301 is used to press the welding material on the outer circle of the welding surface of the artificial graphite 101, and the top pressing block b302 is used to press the welding material on the inner circle of the welding surface of the artificial graphite 101 after the top pressing block a301 is pressed, and a driving component 4 is also arranged between the top pressing components 3, and the driving component 4 drives the top pressing blocks a301 and the top pressing blocks b302 to perform reciprocating pressing alternately in sequence by rotating.

[0030] When the present invention is working, the pressing component 3 and the driving component 4 are installed and rotated to corresponding positions, and then the graphene particle welding material is buried in the gap between the pressing component 3 and the welding contact surface. Subsequently, the driving component 4 starts the operation to drive the pressing blocks a301 and b302 in the pressing component 3 to reciprocate and press the outer circle and inner circle of the welding material respectively, so that the air in the welding material is exhausted, and the welding material and the welding contact surface are fitted more tightly and evenly. After the driving component 4 and the pressing component 3 complete the operation, each component is disassembled, reset and returned, and the limiting component 2 then brings the contact surfaces of the two pieces of artificial graphite closer and compacts them.

[0031] Here, the limiting component 2 of the present invention limits and fixes the artificial graphite 101 to be welded, the pressing component 3 includes a pressing block a301 and a pressing block b302, and the driving component 4 drives the pressing blocks a301 and b302 to rotate and perform reciprocating pressing on the outer circle welding material and the inner circle welding material respectively, and the reciprocating pressing operation can make the welding material fit more closely with the welding contact surface, and the reciprocating and alternating pressing of the outer circle and the inner circle of the welding material by the pressing blocks a301 and b302 can make the air in the welding material be removed more thoroughly, which is beneficial to improving the subsequent welding quality, and also saves the disadvantages of long-term manual pressure and compaction.

[0032] See attached Figure 2Specifically, the limit assembly 2 includes a limit platform 201 fixedly arranged on the supporting platform 1, and an inverted "T"-shaped slide groove 202 is arranged at four positions on the limit platform 201, and a limit block a203, a limit block b204, a limit block c205 and a limit block d206 are respectively slidably arranged on the inverted "T"-shaped slide groove 202. The inverted "T"-shaped slide groove 202 can make the limit blocks a203, the limit blocks b204, the limit blocks c205 and the limit blocks d206 more stable when sliding during limit adjustment, thereby preventing the artificial graphite 101 from sliding and displacement.

[0033] See attached Figure 3 and attached Figure 4 Specifically, the top pressing assembly 3 includes a pick-and-place groove 303 and a top pressing groove 304 arranged on the inner sides of the limit block a203 and the limit block b204. The top pressing block a301 is slidably arranged in the top pressing groove 304 through the pick-and-place groove 303. A return spring a305 is connected between the top pressing block a301 and the side wall of the top pressing groove 304. The top pressing block a301 can be installed and removed through the set pick-and-place groove 303. One end of the return spring a305 is fixedly arranged on the side wall of the top pressing groove 304, and the other end can be fixedly connected with the sliding column of the top pressing block a301 by hooking. The return spring a305 drives the top pressing block 301 to reset and retreat through the self-recovery force of tensile deformation.

[0034] See attached Figure 4 Specifically, a pressing block b302 is slidably arranged inside the pressing block a301, a return spring b306 is connected between the pressing block b302 and the inner wall of the pressing block a301, a plurality of ventilation holes are provided on the pressing blocks a301 and b302, and the setting principle of the return spring b306 is the same as that of the return spring a305. The plurality of ventilation holes provided on the pressing blocks a301 and b302 are more conducive to the discharge of air in the welding material.

[0035] See attached Figure 5 Specifically, the driving assembly 4 includes a rotating lifting seat 401 arranged on the limit block a203, a driving seat 402 is rotatably arranged on the rotating lifting seat 401, and a driving motor 403 and a driving gear 404 driven by the driving motor 403 are fixedly arranged on the driving seat 402.

[0036] See attached Figure 5 Specifically, a rotating seat 405 is fixedly provided on both sides of the driving motor 403, a driven shaft 406 is rotatably provided on the rotating seat 405, and a driven gear 407 meshing with the driving gear 404 is provided on the driven shaft 406. The driving motor 403 drives the driving gear 404 to rotate, and the rotation of the driving gear 404 drives the two meshing driven gears 407 to rotate, thereby realizing the circular rotation of the driven shaft 406 on the rotating seat 405.

[0037] See attached Figure 5 Specifically, cam a408, cam b409 and cam c410 are respectively provided at the bottom of the driven shaft 406. The size directions of cam a408 and cam c410 are consistent. The protruding direction of cam b409 is perpendicular to the protruding directions of cam a408 and cam c410. Cam a408 and cam c410 are respectively provided on the upper and lower sides of the top pressure block a301 to drive the top pressure block a to move back and forth for pressing. Cam b409 is provided on the middle side of the top pressure block b, and the protruding direction is perpendicular to the protruding directions of cam a408 and cam c410. The reciprocating alternating pressing of the top pressure block a301 and the top pressure block b302 is realized by the setting of the above three cams during rotation.

[0038] It should be noted that the welding material of the present invention is pre-buried on the welding contact surface, and the pressing block a301 and the pressing block b302 are driven by the driving assembly 4 to perform alternate reciprocating pressing. The pressing block a301 first presses the outer ring of the welding material (as shown in the attached figure). Figure 8 As shown in the figure, the air inside the outer ring of the welding material is discharged to the outside and through the vent on the top pressure block a301 under the top pressure, and then the top pressure block b302 presses the inner ring of the welding material (as shown in the figure). Figure 7 As shown in the figure, a small amount of air in the inner circle of the welding material will be transferred to the outer circle of the welding material, and part of the air will be discharged through the vent on the top pressure block b302. By repeatedly alternating the top pressure, the air in the welding material on the entire contact surface can be completely eliminated. If a single top pressure block is used for repeated top pressure, some air will always remain in the welding material and cannot be discharged smoothly.

[0039] It is worth mentioning that the present invention can ensure that the thickness of the welding material on the contact surface is uniform by reciprocatingly pressing the welding material on the graphite welding contact surface through the pressing component 3, and the welding material fits more tightly at various parts of the contact surface, thereby ensuring the stability of the strength of various parts on the subsequent welding section and improving the stability of artificial graphite welding.

[0040] Embodiment 2

[0041] As attached Figure 6 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding figure marks in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that: a flattening component 5 is also provided on the limit block b204, and the flattening component 5 includes a rotating drive seat 501, and a top pressure seat 502 is rotatably provided on the rotating drive seat 501, and a cylinder 503 and a flattening bar 504 pushed by the cylinder 503 are fixedly provided on the top pressure seat 502. After the artificial graphite 101 is close to each other, the flattening component 5 can push the flattening bar 504 through the cylinder 503 to compact and flatten the welding material between the graphite welding contact surfaces.

[0042] It is particularly noted that the welding material of the present invention is made of nano-graphite powder, anhydrous alcohol and phenolic resin, which are stirred and mixed into sticky graphene particles. After the top pressure component 3 presses the welding material, the limit component 2 drives the welding surfaces of the two artificial graphites 101 to be close and leave a gap. The gap range is 1-5mm, preferably 3mm. Then the flattening component 5 finally compacts the welding material in the gap as a whole and flattens the surface. Subsequently, an acetylene oxygen gun is used to heat the welding section, and the temperature is maintained at 2100-2500 degrees Celsius, preferably 2300 degrees Celsius. The heating time is maintained at 5-30 minutes according to the size range of the gap. After the welding section is heated, the graphene will turn red, and the artificial graphite molecules will blend and grow with each other to achieve a welding fixation effect. After the welding is heated, dry ice is used for cooling, and the cooling time is 10-15 minutes.
