[0001] This utility model belongs to the field of silicon carbide heating rod processing technology, and in particular relates to a forming device for silicon carbide heating rods. Background Technology

[0002] Silicon carbide heating rods are important electric heating elements, whose main raw materials are silicon carbide powder and binders. Silicon carbide heating rods are widely used in various heating appliances and equipment. In household appliances, silicon carbide heating rods are commonly used in showers, water dispensers, water heaters, dishwashers, and other appliances to provide stable and efficient heating functions for these devices. In the industrial field, silicon carbide heating rods are widely used in heating water tanks, oil tanks, acid and alkali tanks, as well as in the heating systems of equipment such as fusible metal melting furnaces, air heating furnaces, and drying ovens. In the production process of silicon carbide heating rods, cutting and processing is an important step, which can cut the silicon carbide heating rods into the required shape and size.

[0003] The problem with the existing technology is that if no positioning measures are taken when the silicon carbide heating rod is cut and shaped, the silicon carbide heating rod may shift or shake during the cutting process, resulting in errors in the dimensions after cutting and affecting the cutting effect of the silicon carbide heating rod. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a forming device for silicon carbide heating rods, which has the advantage of positioning and clamping the silicon carbide heating rod to be processed, and then cutting and forming it. This solves the problem that if no positioning measures are taken when cutting and forming the silicon carbide heating rod, the silicon carbide heating rod may shift or shake during the cutting process, resulting in errors in the dimensions after cutting and affecting the cutting effect of the silicon carbide heating rod.

[0005] This utility model is implemented as follows: a molding device for a silicon carbide heating rod includes an operating table, a cutting machine, a limiting block, a working groove, and a locking structure. The top of the operating table has a groove, and a placement strip is fixedly connected to the inner wall of the groove. A pushing cylinder is fixedly connected to the right side of the top of the operating table, and the output end of the pushing cylinder is fixedly connected to the cutting machine. A support arm is fixedly connected to the rear side of the top of the operating table, and a lower pressing arm is rotatably connected to the top of the support arm via a rotating shaft. A connecting block is fixedly connected to the bottom of the front end of the lower pressing arm. Connecting slots are provided on the left and right sides of the block. A lower pressure pad is fixedly connected to the bottom of the lower pressure arm. A limiting block is fixedly connected to the top of the front of the operating table. A slot is provided at the bottom of the front of the operating table. A working groove is provided on the inner wall of the limiting block. An opening is provided at the top of the limiting block. The connecting block is inserted into the inner wall of the opening. A straight-moving groove is provided at the bottom of the limiting block. The working groove is connected to both the opening and the straight-moving groove. Straight-moving rods are fixedly connected to the left and right sides of the inner wall of the working groove. A locking structure is provided on the inner wall of the working groove.

[0006] In a preferred embodiment of this invention, the locking structure includes a displacement block disposed at the bottom of the limiting block. The outer surface of the displacement block is slidably connected to the inner wall of the straight sliding groove. A pusher is fixedly connected to the bottom of the displacement block, and a displacement arm is fixedly connected to the top of the displacement block. By setting the displacement block, when the pusher is pressed backward, it can drive the displacement block to slide backward in the straight sliding groove, thereby driving the movement of the displacement arm.

[0007] In a preferred embodiment of this invention, the displacement arm is disposed on the inner wall of the working groove, the bottom of the displacement arm is fixedly connected to the top of the displacement block, and displacement rods are fixedly connected to the left and right ends of the top of the displacement arm, respectively. Linkage arms are respectively sleeved on the outer surfaces of the two displacement rods. By setting the displacement arm, the displacement arm can be driven by the displacement block to move backward in the working groove, synchronously driving the movement of the two displacement rods. Thus, when the two displacement rods move, they respectively drive the two linkage arms to rotate.

[0008] In a preferred embodiment of this invention, the two linkage arms are respectively disposed on the inner walls of the working groove. The ends of the two linkage arms that are close to each other are rotatably connected to the inner walls of the working groove via rotating shafts. The ends of the two linkage arms that are far apart from each other are respectively provided with linkage grooves. The inner walls of the two linkage grooves that are far apart from each other are respectively attached to the outer surfaces of the two displacement rods. The ends of the two linkage arms that are close to each other are respectively fixedly connected to extension arms. By setting the linkage arms, the two displacement rods squeeze the two linkage grooves while moving backward, thereby driving the two linkage arms to rotate relative to each other. Thus, when the two linkage arms rotate, they can respectively drive the two extension arms to rotate synchronously.

[0009] In a preferred embodiment of this invention, the rear ends of the two extension arms are respectively fixedly connected to the front sides of the two linkage arms that are close to each other. The front sides of the two extension arms are respectively provided with openings, and the front ends of the two extension arms that are far apart from each other are respectively provided with locking arms. By providing extension arms, the two extension arms can be staggered through the openings during rotation and push the two locking arms, thereby driving the two locking arms to move away.

[0010] In a preferred embodiment of this invention, the two locking arms are slidably connected to the outer surface of the linear guide rod at their midpoints. The sides of the two locking arms that are close to each other are respectively attached to the two extension arms. The sides of the two locking arms that are far apart from each other are respectively fixedly connected to locking springs. Both locking springs are sleeved on the outer surface of the linear guide rod. The ends of the two locking springs that are far apart from each other are respectively fixedly connected to the inner wall of the working groove. The tops of the two locking arms are respectively fixedly connected to locking blocks. By setting the locking arms, the two locking arms can be pushed by the extension arms respectively, slide away on the linear guide rod, and compress the two locking springs respectively. The sliding of the two locking arms then drives the two locking blocks to move away respectively.

[0011] As a preferred embodiment of this utility model, the two locking blocks are respectively fixedly connected to the top of the two locking arms on the side that is close to each other. The ends of the two locking blocks that are close to each other are respectively inserted into the inner wall of the connecting groove. By setting the locking blocks, the locking blocks can be disengaged from the connecting groove when they move away, thereby releasing the fixing of the connecting blocks and releasing the fixed connection between the limiting block and the lower pressure arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem that if no positioning measures are taken when cutting silicon carbide heating rods, the existing silicon carbide heating rods may shift or shake during the cutting process, resulting in dimensional errors after cutting and affecting the cutting effect of the silicon carbide heating rods, by setting up an operating table, a cutting machine, a limiting block, a working groove, and a locking structure.

[0014] 2. This utility model, by setting a cutting machine and a limiting block, enables the working groove and the locking structure to work together. The locking structure fixes the connecting block inserted into the opening, thereby fixing and limiting the lower pressure arm. The silicon carbide heating rod to be processed is positioned and clamped on the top of the operating table by the lower pressure pad. Then, the cutting machine cuts and processes it into shape, ensuring that the silicon carbide heating rod remains stable during the cutting process, preventing cutting size errors caused by deviation or shaking, and ensuring the cutting and forming effect of the silicon carbide heating rod.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown in the figure, a silicon carbide heating rod forming device provided by this utility model embodiment includes an operating table 1, a cutting machine 2, a limiting block 3, a working groove 4, and a locking structure 5. A groove 101 is formed on the top of the operating table 1, and a placement strip 102 is fixedly connected to the inner wall of the groove 101. A push cylinder 103 is fixedly connected to the right side of the top of the operating table 1, and the output end of the push cylinder 103 is fixedly connected to the cutting machine 2. A support arm 104 is fixedly connected to the rear side of the top of the operating table 1. A lower pressing arm 6 is rotatably connected to the top of the support arm 104 via a rotating shaft. A connecting block 7 is fixedly connected to the bottom of the front end of the lower pressing arm 6. Connecting slots 701 are provided on the left and right sides of the 7. A lower pressure pad 601 is fixedly connected to the bottom of the lower pressure arm 6. A limiting block 3 is fixedly connected to the top of the front of the operating table 1. A slot 105 is provided at the bottom of the front of the operating table 1. A working slot 4 is provided on the inner wall of the limiting block 3. An opening 301 is provided on the top of the limiting block 3. The connecting block 7 is inserted into the inner wall of the opening 301. A straight movement slot 302 is provided at the bottom of the limiting block 3. The working slot 4 is connected to both the opening 301 and the straight movement slot 302. A straight movement rod 401 is fixedly connected to the left and right sides of the inner wall of the working slot 4. A locking structure 5 is provided on the inner wall of the working slot 4.

[0023] refer to Figure 3 and Figure 4 The locking structure 5 includes a displacement block 8, which is located at the bottom of the limiting block 3. The outer surface of the displacement block 8 is slidably connected to the inner wall of the straight sliding groove 302. A pusher 9 is fixedly connected to the bottom of the displacement block 8, and a displacement arm 10 is fixedly connected to the top of the displacement block 8.

[0024] The above scheme is adopted: by setting the displacement block 8, when the pusher 9 is pressed backward, it can drive the displacement block 8 to slide backward in the straight sliding groove 302, and the sliding displacement block 8 can drive the movement of the displacement arm 10.

[0025] refer to Figure 4 The displacement arm 10 is set on the inner wall of the working groove 4. The bottom of the displacement arm 10 is fixedly connected to the top of the displacement block 8. The left and right ends of the top of the displacement arm 10 are respectively fixedly connected to the displacement rods 11, and the outer surfaces of the two displacement rods 11 are respectively sleeved with the linkage arms 12.

[0026] The above scheme is adopted: by setting up a displacement arm 10, the displacement arm 10 can be driven by the displacement block 8 to move backward in the working groove 4, and simultaneously drive the movement of the two displacement rods 11. When the two displacement rods 11 move, they respectively drive the two linkage arms 12 to rotate.

[0027] refer to Figure 4Two linkage arms 12 are respectively positioned on the inner wall of the working groove 4. The ends of the two linkage arms 12 that are close to each other are rotatably connected to the inner wall of the working groove 4 through a rotating shaft. The ends of the two linkage arms 12 that are far apart from each other are respectively provided with linkage grooves 13. The ends of the inner walls of the two linkage grooves 13 that are far apart from each other are respectively in contact with the outer surfaces of the two displacement rods 11. The ends of the two linkage arms 12 that are close to each other are respectively fixedly connected with extension arms 14.

[0028] The above solution is adopted: by setting the linkage arm 12, the two displacement rods 11 press the two linkage grooves 13 while moving backward, thereby driving the two linkage arms 12 to rotate relative to each other. In this way, when the two linkage arms 12 rotate, they can drive the two extension arms 14 to rotate synchronously.

[0029] refer to Figure 4 The rear ends of the two extension arms 14 are fixedly connected to the front of the two linkage arms 12 at one end close to each other. The front of the two extension arms 14 is provided with an opening 15, and the front ends of the two extension arms 14 are provided with locking arms 16 on the opposite sides.

[0030] The above solution is adopted: by setting up extension arms 14, the two extension arms 14 can be offset from the straight moving rod 401 through the through port 15 during rotation, and push the two locking arms 16, thereby driving the two locking arms 16 to move away.

[0031] refer to Figure 4 The two locking arms 16 are slidably connected to the outer surface of the linear rod 401 in the middle. The sides of the two locking arms 16 that are close to each other are respectively attached to the two extension arms 14. The sides of the two locking arms 16 that are far apart from each other are respectively fixedly connected to locking springs 17. Both locking springs 17 are sleeved on the outer surface of the linear rod 401. The ends of the two locking springs 17 that are far apart from each other are respectively fixedly connected to the inner wall of the working groove 4. The tops of the two locking arms 16 are respectively fixedly connected to locking blocks 18.

[0032] The above solution is adopted: by setting locking arms 16, the two locking arms 16 can be pushed by the extension arm 14 respectively, slide away on the straight rod 401, and compress the two locking springs 17 respectively. The two locking arms 16 slide and then drive the two locking blocks 18 to move away respectively.

[0033] refer to Figure 3 and Figure 4 Two locking blocks 18 are fixedly connected to the top of the two locking arms 16 on the side that are close to each other, and the ends of the two locking blocks 18 that are close to each other are respectively inserted into the inner wall of the connecting groove 701.

[0034] The above solution is adopted: by setting a locking block 18, the locking block 18 can be disengaged from the connecting groove 701 when it moves away, thereby releasing the fixation of the connecting block 7 and thus releasing the fixed connection between the limiting block 3 and the lower pressure arm 6.

[0035] The working principle of this utility model:

[0036] In use, the silicon carbide heating rod to be processed is placed in the placement strip 102, and its cutting position is determined by the groove 101. Then, the lower pressure arm 6 is rotated downward, causing the lower pressure pad 601 and the connecting block 7 to move. The lower pressure pad 601 is attached to the top of the silicon carbide heating rod, and the connecting block 7 is inserted into the opening 301. As the connecting block 7 moves downward, it presses the surfaces of the two locking blocks 18, causing them to move and drive the two locking arms 16 to slide away on the straight-moving rod 401, compressing the two locking springs 17. When the connecting block 7 is fully inserted into the opening 301, the two locking springs 17 push the two locking arms 16 to slide, causing the two locking blocks 18 to move and insert into the connecting groove 701 to fix the connecting block 7. This fixes the lower pressure arm 6 to the limiting block 3, and positions and clamps the silicon carbide heating rod through the lower pressure pad 601. Then, the push cylinder 103 pushes the cutting machine 2 to move. The silicon carbide heating rod is cut and processed in conjunction with the groove 101. After completion, the pusher 9 is pressed backward, causing the displacement block 8 to move backward in the straight groove 302 and the displacement arm 10 to move in the working groove 4. Simultaneously, the two displacement rods 11 move backward and press the two linkage grooves 13, causing the two linkage arms 12 to rotate relative to each other. During the rotation, the two extension arms 14 rotate synchronously. During the rotation, the two extension arms 14 are staggered from the straight rod 401 through the through 15 and push the two locking arms 16 to slide away from the straight rod 401. While the two locking springs 17 are compressed, the two locking blocks 18 move away from the connecting groove 701 to release the fixation of the connecting block 7. This releases the fixed connection between the limiting block 3 and the lower pressing arm 6. Then, the lower pressing arm 6 is rotated upward, and the cut silicon carbide heating rod can be taken out.

[0037] It should be noted that the drive cylinder 103 and the cutting machine 2 are existing devices or equipment, or devices or equipment that can be implemented by existing technology, and the specific composition and principle of the power supply of the drive cylinder 103 and the cutting machine 2 are clear to those skilled in the art, so they will not be described in detail here.

[0038] In summary, the forming device for this silicon carbide heating rod, through the coordinated operation of the operating table 1, the cutting machine 2, the limiting block 3, the working groove 4, and the locking structure 5, solves the problem that if no positioning measures are taken when cutting and forming the silicon carbide heating rod, the silicon carbide heating rod may shift or shake during the cutting process, resulting in dimensional errors after cutting and affecting the cutting effect of the silicon carbide heating rod.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
