Description

Technical Field

[0001] The invention belongs to the technical field of reaction vessel forming equipment, and in particular relates to an electrode material reaction vessel forming equipment and a forming method. Background Art

[0002] The reaction vessel is mainly used for the heat treatment process of raw materials and precursor materials of battery electrodes. When used, the raw materials and precursor materials are placed in the reaction vessel, and then heat treated in a roller kiln or tunnel kiln. After the heat treatment in the kiln is completed, the kiln is taken out after cooling, the material in the reaction vessel is taken out, and new raw materials and precursor materials are put in for the next cycle. The reaction vessel needs to be pressed and formed by a hydraulic press during the production process.

[0003] In the prior art (the announcement number is CN117863320B, and the patent name is a patent application for a graphite crucible pressing and forming device), the forming mold, support plate, and nozzle are used in combination. When the piston tube moves up inside the infusion cylinder and pushes the graphite crucible out of the forming mold with the support plate, the nozzle at the bottom of the support plate sprays the release agent on the inner wall of the forming cavity. At the same time, the reaction force of the spraying of the nozzle rotates the drainage ring sleeve, so that the sprayed release agent can be evenly attached. By brushing the release agent simultaneously during the demolding process, it is avoided to brush the release agent separately after demolding, thereby improving work efficiency. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art.

[0004] During the molding of reaction vessels, bubbles are easily mixed in after pouring raw materials, resulting in an uneven surface of the reaction vessel after molding, which affects the use effect and service life of the reaction vessel. During the use of some existing reaction vessel molding equipment, due to the strong adhesion between the raw materials and the mold surface, it is difficult to eject the molded reaction vessel, and the work efficiency is low; after the reaction vessel is molded, a small amount of raw material powder will adhere to the inner wall of the pressing mold.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The electrode material reaction vessel forming equipment first adds raw materials into the heated lower mold located at the bottom of the lower pressing mold, and the hydraulic cylinder pushes the lifting connection frame to slide on the lifting rod, and the lifting connection frame drives the lower pressing mold to descend, and the lower pressing mold squeezes the raw materials in the heated lower mold. During the pressing process, the lifting connection frame drives the connection frame, the driving rod and the driving gear to descend. Because the driving gear is engaged with the tooth plate, the driving gear can drive the driving rod and the active bevel gear to rotate, so that the active bevel gear drives the driven bevel gear and the lower pressing mold to rotate. When the lower pressing mold rotates, the rotation of the lower pressing mold can help to better discharge the air in the raw materials and prevent the formation of bubbles, thereby improving the quality of the product. The rotation of the lower pressing mold during the lifting process can make the material more evenly distributed inside the mold, which helps to obtain a smoother and finer surface quality, and can increase the fluidity of the material so that the material can better fill every corner of the mold. After the pressing is completed, the adhesion can be reduced by rotating the lower pressing mold during the rising process, which helps the product to be more easily separated from the lower pressing mold.

[0024] 2. The electrode material reaction vessel forming equipment drives the motor to start, and drives the driving seat to move through the threaded rotating rod, and the driving seat drives the molding box and the heated lower mold to move. When the reaction vessel after press forming is moved out of the pressing area through the first heated lower mold, another heated lower mold enters the pressing area for a new round of press forming, thereby realizing continuous production, improving production efficiency, improving equipment utilization, and shortening the production cycle.

[0025] 3. For the electrode material reaction vessel forming equipment, when the forming box is placed away from the pressing area, the guide slide bar moves in the limiting groove. When the guide slide bar moves on the inclined groove surface, the guide slide bar drives the driving ring to rotate through the connecting rod. When the driving ring rotates, the limiting slide bar slides in the limiting groove, thereby causing the limiting slide bar to drive the sealing disk to rotate with the fixed axis as the axis, thereby keeping the sealing disk away from the reaction vessel during the opening process, preventing the reaction vessel from sticking to the sealing disk, and ensuring that the formed reaction vessel can be easily taken out of the heated mold.

[0026] 4. The electrode material reaction vessel forming equipment, the subsequently formed reaction vessel falls onto the pushing circular plate, the placing forming box continues to drive the L-shaped fixing frame, the limiting groove and the guide lifting rod to move, when the guide lifting rod moves from the straight groove surface of the lifting groove plate to the slope surface, the guide lifting rod drives the pushing piece to rise, and the rising pushing piece drives the pushing circular plate and the formed reaction vessel to rise, so that the reaction vessel is separated from the heated lower mold, ensuring the demolding effect.

[0027] 5. The electrode material reaction vessel forming equipment, when the forming box is placed to drive the L-shaped fixing frame to move, the L-shaped fixing frame squeezes the lower pressing piece, so that the lower pressing piece can drive the extrusion plate to descend, and the descending extrusion plate squeezes the gas in the extrusion box, and the extruded gas enters the exhaust cavity and the exhaust cavity through the exhaust pipe and is discharged from the injection head. Because the pusher circular plate rises in the heated lower mold, the injection head can evenly clean the inside of the heated lower mold, and the heated lower mold can be cooled at the same time.

[0028] 6. When the heated lower mold moves to the reciprocating plate, the lower pressure rod contacts the reciprocating plate, so that the lower pressure rod moves along the reciprocating plate. When the lower pressure rod descends along the inclined surface of the reciprocating plate, the lower pressure rod drives the lower pressure circular plate to squeeze the V-shaped plate, so that the V-shaped plate moves with the hinge frame as the axis. When the lower pressure rod is separated from the inclined surface of the reciprocating plate, the connecting spring pushes the V-shaped plate to reset. When resetting, the V-shaped plate drives the collision ball to collide with the heated lower mold. Vibration is generated through continuous collision, which is beneficial to the demolding of the reaction vessel after molding, and a small amount of raw material powder adhering to the inner wall of the heated lower mold can be cleaned through vibration.

When the guide slide bar 32 moves on the inclined groove surface, the guide slide bar 32 drives the driving ring 303 to rotate through the connecting rod 31. When the driving ring 303 rotates, the limiting slide bar 305 slides in the limiting groove 304, thereby causing the limiting slide bar 305 to drive the sealing disk 306 to rotate around the fixed axis 307 as the axis, thereby causing the sealing disk 306 to be away from the reaction vessel during the opening process, preventing the reaction vessel from adhering to the sealing disk 306, and ensuring that the formed reaction vessel can be easily taken out from the heated lower mold 205.

[0051] like Figures 10 to 13 As shown, the inner wall of the frame 101 is provided with a demoulding and material taking mechanism 5, which includes a lifting slot plate 501 fixedly connected to the inner wall of the frame 101, the inner wall of the lifting slot plate 501 is slidably connected with a guide lifting rod 502, and the end of the guide lifting rod 502 away from the lifting slot plate 501 is fixedly connected with a push piece 503, and the outer wall of the push piece 503 is provided with a limiting groove 504, and the inner wall of the limiting groove 504 is slidably connected with a fixed protrusion 505, and the fixed The outer surface of the protrusion 505 is fixedly connected to an L-shaped fixing frame 506, the top of the L-shaped fixing frame 506 is fixedly connected to the bottom of the molding box 204, and the top of the pushing piece 503 is fixedly connected to a pushing circular plate 507. This arrangement is that when the guide lifting rod 502 moves from the straight groove surface to the slope surface of the lifting groove plate 501, the guide lifting rod 502 drives the pushing piece 503 to rise, and the rising pushing piece 503 drives the pushing circular plate 507 and the molding reaction vessel to rise.

This arrangement is for the gas in the extrusion box 601 to enter from the air intake check valve 602. A return spring 603 is fixedly connected to the inner wall of the extrusion box 601, and an extrusion plate 604 is fixedly connected to the top of the return spring 603. A pressing piece 605 is fixedly connected to the top of the extrusion plate 604, and a side wall of the pressing piece 605 is contacted with a side wall of the L-shaped fixing frame 506.

This arrangement allows gas to enter the exhaust cavity 608 and the exhaust cavity 608 through the exhaust pipe 606 and be discharged from the injection head 610. The injection head 610 can clean the interior of the heated lower mold 205 and cool the heated lower mold 205 at the same time.

[0054] like Fig.14 and Fig.15As shown, due to the strong adhesion between the raw material and the surface of the heated lower mold 205, it is difficult to eject the reaction vessel after the molding, and the work efficiency is low; after the molding of the reaction vessel, a large amount of raw material residue will remain on the surface of the heated lower mold 205 after demoulding, which requires a lot of time and manpower to clean up. When the raw material powder is not cleaned up in time, it affects the next molding. The interior of the molding box 204 is provided with an oscillation mechanism 7, and the oscillation mechanism 7 includes an articulated frame 701 fixedly connected to the inner wall of the molding box 204, and the side wall of the articulated frame 701 is rotatably connected to a V-shaped plate 702, and the side wall of the V-shaped plate 702 is fixedly connected to a connecting spring 703, and the end of the connecting spring 703 away from the V-shaped plate 702 is fixedly connected to the inner wall of the molding box 204, and the bottom end of the V-shaped plate 702 is fixedly connected to a collision ball 704, and the inner wall of the molding box 204 is fixedly connected to a fixed sliding column 705, and the outer wall of the fixed sliding column 705 is slidably connected to a downward pressing circular plate 706, and the top of the downward pressing circular plate 706 is fixedly connected to The lower pressing rod 707 is connected, and the lower pressing rod 707 penetrates the inner wall of the molding box 204 and extends to the outside. The top of the support guide rail 207 is fixedly connected with a reciprocating plate 708. The purpose of this arrangement is that when the heated lower mold 205 moves to the reciprocating plate 708, the lower pressing rod 707 contacts the reciprocating plate 708, so that the lower pressing rod 707 moves along the reciprocating plate 708. When the lower pressing rod 707 descends along the inclined surface of the reciprocating plate 708, the lower pressing rod 707 drives the lower pressing circular plate 706 to V-shaped The plate 702 is squeezed, so that the V-shaped plate 702 moves with the hinge frame 701 as the axis.

When resetting, the V-shaped plate 702 drives the collision ball 704 to collide with the heated lower mold 205. Vibration is generated through continuous collision, which is beneficial to the demoulding of the reaction vessel after molding, and a small amount of raw material powder adhering to the inner wall of the heated lower mold 205 can be cleaned through vibration.

[0055] like Fig.16 As shown, a method for forming an electrode material reaction vessel, the specific preparation steps are as follows:

[0056] S1: Prepare the following components in weight percentage: 38-39% corundum powder, 20-25% mullite, 15-19% cordierite, 15-20% alumina powder, 1-2% calcium lignin sulfonate, and 2-4% dextrin; after preparing the materials, mix them to form a mud material; wherein the mullite of the present invention is 1-3mm, the cordierite is 1-2mm, and the alumina powder is 200-320 mesh;

[0057] S2: placing the clay material into the heated lower mold 205 and pressing it into the shape and size of the desired reaction vessel;

[0058] S3: placing the formed reaction vessel into a drying oven for drying to remove moisture therein;

[0059] S4: The dried reaction vessel is placed in a firing kiln and fired at 1300-1400°C to cause the mineral materials therein to undergo a solid phase reaction to form a high-strength reaction vessel.

[0060] The working principle of an electrode material reaction vessel forming device is as follows: first, raw materials are added into the heated lower mold 205 located at the bottom of the lower pressing mold 43, and the hydraulic cylinder 403 pushes the lifting connection frame 404 to slide on the lifting rod 401, and the lifting connection frame 404 drives the lower pressing mold 43 to descend, and the lower pressing mold 43 squeezes the raw materials in the heated lower mold 205. During the pressing process, the lifting connection frame 404 drives the connection frame 46, the driving rod 45 and the driving gear 47 to descend. Because the driving gear 47 is meshed with the tooth plate 48, the driving gear 47 can drive the driving rod 45 and the active bevel gear 44 to rotate, so that the active bevel gear 44 is driven to rotate. The bevel gear 44 drives the driven bevel gear 42 and the pressing die 43 to rotate. When the pressing die 43 rotates, the rotation of the pressing die 43 can help to better discharge the air in the raw material and prevent the formation of bubbles, thereby improving the quality of the product. The rotation of the pressing die 43 during the lifting process can make the material more evenly distributed inside the mold, which helps to obtain a smoother and finer surface quality, and can increase the fluidity of the material so that the material can better fill every corner of the mold. After the pressing is completed, the rotation of the pressing die 43 during the rising process can reduce the adhesion, which helps the product to be more easily separated from the pressing die 43.

[0061] The driving motor 201 is started, and the driving seat 203 is driven to move through the threaded rotating rod 202, and the driving seat 203 drives the placing molding box 204 and the heating lower mold 205 to move. The reaction vessel after the pressing and molding is moved out of the pressing area through the first heating lower mold 205, and the other heating lower mold 205 enters the pressing area for a new round of pressing and molding, thereby realizing continuous production, improving production efficiency, improving equipment utilization, and shortening the production cycle. When the placing molding box 204 is far away from the pressing area, the guide slide bar 32 moves in the limiting groove 34. When the guide slide bar 32 moves on the inclined groove surface, the guide slide bar 32 drives the driving ring 303 to rotate through the connecting rod 31. When the driving ring 303 rotates, the limiting slide bar 305 slides in the limiting groove 304, so that the limiting slide bar 305 drives the blocking disk 306 to rotate with the fixed axis 307 as the axis, so that the blocking disk 306 is kept away from the reaction vessel during the opening process, preventing the reaction vessel from adhering to the blocking disk 306, and ensuring that the formed reaction vessel can be easily taken out from the heated lower mold 205;

[0062] Subsequently, the formed reaction vessel falls onto the pushing circular plate 507, and the placing molding box 204 continues to drive the L-shaped fixing frame 506, the limiting groove 504 and the guide lifting rod 502 to move. When the guide lifting rod 502 moves from the straight groove surface to the slope surface of the lifting groove plate 501, the guide lifting rod 502 drives the pushing piece 503 to rise, and the rising pushing piece 503 drives the pushing circular plate 507 and the formed reaction vessel to rise, so that the reaction vessel is separated from the heated lower mold 205, ensuring the demolding effect.

[0063] When the molding box 204 is placed and drives the L-shaped fixing frame 506 to move, the L-shaped fixing frame 506 squeezes the lower pressing piece 605, so that the lower pressing piece 605 drives the extrusion plate 604 to descend, and the descending extrusion plate 604 squeezes the gas in the extrusion box 601, and the extruded gas enters the exhaust cavity 608 and the exhaust cavity 608 through the exhaust pipe 606 and is discharged from the injection head 610. Because the pushing circular plate 507 rises in the heated lower mold 205, the injection head 610 can evenly clean the inside of the heated lower mold 205, and at the same time, the heated lower mold 205 can be cooled down.

[0064] When the heated lower mold 205 moves to the reciprocating plate 708, the lower pressure rod 707 contacts the reciprocating plate 708, so that the lower pressure rod 707 moves along the reciprocating plate 708. When the lower pressure rod 707 descends along the inclined surface of the reciprocating plate 708, the lower pressure rod 707 drives the lower pressure circular plate 706 to squeeze the V-shaped plate 702, so that the V-shaped plate 702 moves with the hinge frame 701 as the axis. When the lower pressure rod 707 disengages from the inclined surface of the reciprocating plate 708, the connecting spring 703 pushes the V-shaped plate 702 to reset. When resetting, the V-shaped plate 702 drives the collision ball 704 to collide with the heated lower mold 205. Vibration is generated through continuous collision, which is beneficial to the demolding of the reaction vessel after molding, and a small amount of raw material powder adhering to the inner wall of the heated lower mold 205 can be cleaned through vibration.

[0065] It should be noted that the specific models and specifications of the drive motor 201, the heated lower mold 205, and the hydraulic cylinder 403 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0066] The principles of the driving motor 201, the heating lower mold 205, and the hydraulic cylinder 403 are clear to those skilled in the art and will not be described in detail herein.
