Description

Technical Field

[0001] This invention relates to the field of solder manufacturing tools, specifically to a solder casting and forming device for drill bits. Background Technology

[0002] Drilling bit filler metals, including copper-based filler metals, silver-based filler metals, phosphor bronze filler metals, composite metal filler metals, tin-lead soft filler metals, copper and copper alloy welding wires, and aluminum and aluminum alloy welding wires, require the mixing of base materials and admixtures (such as cobalt, molybdenum, nickel, etc.) and casting to facilitate subsequent rolling, stamping and other processes.

[0003] In the prior art, Chinese patent publication number "CN214133838U" discloses a solder casting forming device for drill bits. This device involves pressing a second clamping plate against the long outer wall of the second mold, a first clamping plate against the short outer wall of the first mold, a third clamping plate against the short outer wall of the second mold, and a fourth clamping plate against the long outer wall of the first mold, then engaging and tightening them with locking screws. At this point, mold closing is complete, and molten solder can be poured into the internal cavity of the mold. After cooling and forming, the mold can be disassembled. This device enables rapid mold closing and separation, facilitates solder casting, and is easy to operate and adjust. It solves the problems of existing casting molds having unreasonable structures and being inconvenient to operate and adjust.

[0004] In the above scheme, the operator needs to manually align the parting surfaces of the first and second modules and apply initial pressing force to make them fit together. Since manual alignment is required, the accuracy is low. Then, multiple sets of clamping plates and locking screws are operated in sequence. Since each clamping plate needs to be tightened manually, it is difficult to control the tightening torque of each locking screw uniformly, which can easily cause uneven lateral force on the mold. Long-term use may lead to mold deformation or wear of the parting surface, affecting the surface finish and contour clarity of the solder casting. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a welding casting apparatus for drill bits, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A welding casting device for drill bits includes a device base frame, a mold locking mechanism, and a forming mold mounted on the device base frame. The forming mold is mounted on the device base frame via the mold locking mechanism. The mold-locking mechanism includes a clamping assembly, a pressing assembly, and a blocking assembly, wherein the clamping assembly is connected to the pressing assembly, and the blocking assembly is connected to the clamping assembly; The clamping assembly is used to clamp the forming mold from the side to define its outline and resist the lateral expansion force generated by the molten solder during the pouring process. The pressing assembly is used to press the forming mold onto the device base from above. The clamping assembly contacts the forming mold before the clamping assembly locks, so that the forming mold fits against the device base and provides a positioning reference for the pressing assembly.

[0007] Preferably, the clamping assembly includes a hydraulic cylinder fixedly mounted on the device base frame. A lower pressure plate is fixedly mounted on the output shaft of the hydraulic cylinder. A lower connecting frame is fixedly mounted on the side end face of the lower pressure plate. A lower pressing connecting rod is rotatably connected to the lower connecting frame. A translation groove is formed on the upper end face of the device base frame. A translation slider is slidably mounted inside the translation groove. An upper connecting frame is fixedly mounted on the lower end face of the translation slider. A translation connecting rod is fixedly mounted on the upper end face of the translation slider. A clamping plate is fixedly mounted on the end of the translation connecting rod away from the translation slider. The end of the lower pressing connecting rod away from the lower connecting frame is rotatably connected to the upper connecting frame.

[0008] Preferably, a vertical rod is fixedly installed on the base frame of the device, and the vertical rod is slidably engaged with the lower pressure plate to constrain the lower pressure plate to perform vertical reciprocating motion.

[0009] Preferably, the pressing link is arranged at an angle, and the bottom end of the clamping plate slides against the upper end surface of the device base.

[0010] Preferably, the clamping assembly includes a fixed vertical rod fixedly installed on the device base frame, an inclined sliding rod fixedly installed at the top end of the fixed vertical rod, a lower pressing vertical rod fixedly installed on the side end face of the lower pressing plate, the top end of the lower pressing vertical rod penetrating the device base frame and rotatably installed with a lower horizontal rod, clamping connecting plates fixedly installed at both ends of the lower horizontal rod, an upper horizontal rod fixedly installed on the inner side of the clamping connecting plate, clamping plates rotatably installed at both ends of the upper horizontal rod, and an inclined sliding hole adapted to one end of the inclined sliding rod is opened on the inner side of the clamping plate.

[0011] Preferably, one end of the inclined slide rod extends into the inclined sliding hole and slides therewith. When the lower pressure plate descends, the lower pressure vertical rod drives the lower horizontal rod and the pressing connecting plate to move downward as a whole. Under the guidance of the inclined slide rod and the inclined sliding hole, the pressing plate moves towards the upper surface of the forming mold and presses down.

[0012] Preferably, the clamping assembly includes a mounting plate fixedly installed on the top of the clamping plate. The end of the mounting plate is provided with a rotating groove. The inner side of the rotating groove is provided with a clamping rotating groove. A clamping rotating shaft is rotatably installed inside the clamping rotating groove. A clamping rotating plate is fixedly installed inside the rotating groove and on the clamping rotating shaft. A clamping torsion spring is sleeved on the outer side of the clamping rotating shaft.

[0013] Preferably, one end of the clamping torsion spring is fixedly connected to the side end face of the clamping rotating plate, and the other end of the clamping torsion spring is fixedly connected to the inside of the clamping rotating groove. The reaction force of the clamping torsion spring is used to make the force-applying end of the clamping rotating plate fit into the molding mold and apply a vertically downward force.

[0014] Preferably, a limiting arc plate is fixedly installed at the top of the mounting plate. The limiting arc plate is located on the flipping path of the clamping rotating plate and is used to limit the initial flipping angle of the clamping rotating plate under the action of the clamping torsion spring.

[0015] Preferably, the forming mold includes a first module and a second module, which are assembled together to form a complete forming mold cavity; a first half-cavity is formed on the side of the first module facing the second module, and a second half-cavity is formed on the side of the second module facing the first module. The first half-cavity and the second half-cavity together form a cavity that matches the shape of the solder for the drill bit when assembled.

[0016] This invention provides a welding and casting apparatus for drill bits. Compared with the prior art, it has the following advantages: 1. This invention uses a hydraulic cylinder to drive the lower pressure plate downwards, and the vertical motion is converted into the horizontal sliding motion of the translation slider via the lower pressure connecting rod. This causes the clamping plate to move towards the center of the forming mold simultaneously from four directions, achieving rapid centering and clamping of the forming mold's outline. The clamping force is output evenly in four directions, fundamentally eliminating the tilting or displacement of the forming mold caused by unilateral load. At the same time, the bottom end of the clamping plate slides against the device base frame, and the flatness of the base frame ensures the verticality of the clamping plate's movement, providing a stable lateral constraint benchmark for subsequent precision clamping. 2. In this invention, during the linear inward movement of the clamping plate, the force-applying end of the clamping rotating plate installed at the top of the clamping plate contacts the side end face of the forming mold before the clamping force. As the clamping plate continues to advance, the clamping torsion spring converts the horizontal thrust into a vertically downward pre-pressure, so that the forming mold is stably pressed onto the working surface of the device base frame before it bears the lateral clamping force and the subsequent pouring expansion force. This pre-pressing action not only eliminates the gap between the bottom surface of the forming mold and the base frame, but also provides a high-precision and definite reference plane for the pressing assembly, avoiding the failure of the pressing force due to the forming mold being suspended. 3. In this invention, as the pressure plate continues to descend, the lower horizontal bar and the clamping plate move synchronously downwards via the lower vertical bar, which in turn drives the upper horizontal bar to move the clamping plate. The inclined sliding bar and the inclined sliding hole are used to guide the vertical downward pressure into a horizontal and inclined composite motion, causing the clamping plate to move towards the upper surface of the forming mold and gradually press it down. After the inclined wedge structure is pressed into place, it forms a geometric self-locking tendency. Even if thermal expansion or equipment vibration occurs during the pouring process, the clamping force will not decrease or loosen, ensuring that the cavity remains closed throughout the entire cycle of molten solder filling and solidification.

[0017] 4. This invention achieves all-round, gapless locking of the bottom, sides, and top of the forming mold by coordinating the pre-pressing positioning of the clamping component, the lateral centering and anti-expansion of the clamping component, and the self-locking and holding of the upper end of the pressing component. The synergistic effect of these three elements effectively solves the problems of unstable mold clamping, difficulty in centering, susceptibility to lateral expansion force pushing open the parting surface, and decreased accuracy caused by thermal vibration in existing drill bit solder casting devices. At the same time, the split mold can be quickly opened and the part removed after the locking is released, which significantly improves the contour clarity, dimensional consistency, and surface finish of the solder casting, and simultaneously improves production efficiency and yield.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 This invention relates to a welding casting device for drill bits, comprising a device base frame 1 and a locking mechanism 2 and a forming mold 3 mounted on the device base frame 1. The forming mold 3 is mounted on the device base frame 1 via the locking mechanism 2. The locking mechanism 2 includes a clamping component 21, a pressing component 22, and a clamping component 23. The clamping component 21 is connected to the pressing component 22, and the clamping component 23 is connected to the clamping component 21. The clamping component 21 is used to clamp the forming mold 3 from the side to define its outline and resist the lateral expansion force generated by the molten welding during casting. The pressing component 22 is used to press the forming mold 3 onto the device base frame 1 from above. The clamping component 23 contacts the forming mold 3 before the clamping component 21 locks, so that the forming mold 3 fits against the device base frame 1, providing a positioning reference for the pressing component 22. The device base frame 1 can be mounted on a flat ground via fixing pins.

[0022] Please see Figures 2-5The clamping assembly 21 includes a hydraulic cylinder 2101 fixedly mounted on the device base frame 1. A lower pressure plate 2102 is fixedly mounted on the output shaft of the hydraulic cylinder 2101. A lower connecting frame 2103 is fixedly mounted on the side end face of the lower pressure plate 2102. A lower pressure connecting rod 2104 is rotatably connected to the lower connecting frame 2103. A translational slide groove 2105 is provided on the upper end face of the device base frame 1. A translational slider 2106 is slidably mounted inside the translational slide groove 2105. An upper connecting frame 2107 is fixedly mounted on the lower end face of the translational slider 2106. A translational connecting rod 2108 is fixedly mounted on the upper end face of the translational slider 2106. A clamping plate 2109 is fixedly mounted on the end of the translational connecting rod 2108 away from the translational slider 2106. The end of the pressure link 2104 away from the lower link 2103 is rotatably connected to the upper link 2107. The lower pressure plate 2102 is driven to move downward by the hydraulic cylinder 2101. The vertical motion is converted into the horizontal sliding of the translation slider 2106 by the lower pressure link 2104, which drives the clamping plate 2109 to move towards the center of the forming mold 3 from four directions simultaneously. This achieves rapid centering and clamping of the outer contour of the forming mold 3. The clamping force is output evenly in four directions, which fundamentally eliminates the tilting or displacement of the forming mold 3 caused by unilateral load. At the same time, the bottom end of the clamping plate 2109 slides against the device base frame 1. The flatness of the base frame ensures the verticality of the movement of the clamping plate 2109, providing a stable lateral constraint reference for subsequent precision clamping.

[0023] In this embodiment, a vertical rod 2110 is fixedly installed on the device base frame 1. The vertical rod 2110 slides with the lower pressure plate 2102 to constrain the lower pressure plate 2102 to perform vertical reciprocating motion. The setting of the vertical rod 2110 ensures that the lower pressure plate 2102 moves smoothly only in the vertical direction, eliminating the horizontal component force caused by the deflection of the output shaft of the hydraulic cylinder 2101 or uneven force, thereby ensuring that the stroke of the lower pressure connecting rod 2104 driving the translation slider 2106 is controllable and improving the clamping repeatability positioning accuracy.

[0024] In this embodiment, the pressing link 2104 is arranged at an angle, and the bottom end of the clamping plate 2109 slides against the upper end surface of the device base 1. The bottom end of the clamping plate 2109 maintains sliding contact with the device base 1, which not only provides auxiliary support for the clamping plate 2109 and prevents it from warping due to overhanging force, but also ensures that the clamping plate 2109 is always perpendicular to the worktable surface of the device base 1 during movement by using the flatness of the device base 1, thereby improving clamping stability.

[0025] Please see Figure 2 and Figure 6The clamping assembly 22 includes a fixed vertical rod 2201 fixedly installed on the device base frame 1. An inclined slide rod 2202 is fixedly installed at the top of the fixed vertical rod 2201. A lower pressing vertical rod 2203 is fixedly installed on the side end face of the lower pressing plate 2102. The top of the lower pressing vertical rod 2203 passes through the device base frame 1 and is rotatably installed with a lower horizontal rod 2204. A clamping connecting plate 2205 is fixedly installed at both ends of the lower horizontal rod 2204. An upper horizontal rod 2206 is fixedly installed on the inner side of the clamping connecting plate 2205. A clamping plate 2207 is rotatably installed at both ends of the upper horizontal rod 2206. An inclined sliding hole 2208 adapted to one end of the inclined slide rod 2202 is opened on the inner side of the clamping plate 2207. The cooperation between the inclined slide rod 2202 and the inclined sliding hole 2208 forms a wedge-shaped guide structure, which uses the inclined surface to convert the vertical pressing motion into a horizontal and inclined composite motion of the clamping plate 2207.

[0026] In this embodiment, one end of the inclined slide bar 2202 extends into and slides into the inclined sliding hole 2208. When the pressure plate 2102 descends, the downward pressure vertical bar 2203 drives the downward horizontal bar 2204 and the pressing plate 2205 to move downward as a whole. Under the guidance of the inclined slide bar 2202 and the inclined sliding hole 2208, the pressing plate 2207 moves towards the upper surface of the forming mold 3 and presses down. When the pressure plate 2102 continues to descend, the downward pressure vertical bar 2203 drives the downward horizontal bar 2204 and the pressing plate 2205 to move downward. The upper crossbar 2206 moves synchronously downward, thereby driving the clamping plate 2207 to move. The inclined sliding rod 2202 and the inclined sliding hole 2208 are used to guide the vertical downward pressure into a horizontal and inclined composite motion, so that the clamping plate 2207 moves towards the upper surface of the forming mold 3 and gradually presses it. After the inclined wedge structure is pressed into place, it forms a geometric self-locking tendency. Even if thermal expansion or equipment vibration occurs during the pouring process, the clamping force will not decrease or loosen, ensuring that the cavity remains closed throughout the entire cycle of molten solder filling and solidification.

[0027] Please see Figures 6-8The clamping assembly 23 includes a mounting plate 2301 fixedly installed on the top of the clamping plate 2109. A rotating groove 2302 is formed at the end of the mounting plate 2301, and a clamping rotating groove 2303 is formed on the inner side of the rotating groove 2302. A clamping rotating shaft 2304 is rotatably mounted inside the clamping rotating groove 2303. A clamping rotating plate 2305 is fixedly installed on the clamping rotating shaft 2304 and inside the rotating groove 2302. A clamping torsion spring 2306 is sleeved on the outer side of the clamping rotating shaft 2304. When the clamping plate 2109 moves linearly inward, the force-applying end of the clamping rotating plate 2305 on the mounting plate 2301 will pre-close the side of the forming mold 3. In the face contact process, during the linear movement of the clamping plate 2109 inward, the force-applying end of the clamping rotating plate 2305 installed at the top of the clamping plate 2109 contacts the side end face of the forming mold 3 before the clamping force. As the clamping plate 2109 continues to advance, the clamping torsion spring 2306 converts the horizontal thrust into a vertically downward pre-pressure, so that the forming mold 3 is stably pressed onto the working surface of the device base frame 1 before it bears the lateral clamping force and the subsequent pouring expansion force. This pre-pressing action not only eliminates the gap between the bottom surface of the forming mold 3 and the base frame, but also provides a high-precision and definite reference plane for the pressing assembly 22, avoiding the failure of the pressing force due to the forming mold 3 being suspended.

[0028] In this embodiment, one end of the clamping torsion spring 2306 is fixedly connected to the side end face of the clamping rotating plate 2305, and the other end of the clamping torsion spring 2306 is fixedly connected to the inside of the clamping rotating groove 2303. By utilizing the reaction force of the clamping torsion spring 2306, the force-applying end of the clamping rotating plate 2305 is made to adhere to the molding mold 3, and a vertically downward force is applied.

[0029] In this embodiment, a limiting arc plate 2307 is fixedly installed on the top of the mounting plate 2301. The limiting arc plate 2307 is located on the flipping path of the clamping rotating plate 2305 and is used to limit the initial flipping angle of the clamping rotating plate 2305 under the action of the clamping torsion spring 2306.

[0030] Please see Figure 1The forming mold 3 includes a first module 31 and a second module 32, which are assembled together to form a complete forming mold cavity. A first half-cavity 33 is opened on the side of the first module 31 facing the second module 32, and a second half-cavity 34 is opened on the side of the second module 32 facing the first module 31. The first half-cavity 33 and the second half-cavity 34 together form a cavity that matches the shape of the solder for the drill bit when assembled. By designing the forming mold 3 as a split structure, it is easy to quickly open the mold and remove the part after the solder solidifies. At the same time, the first module 31 and the second module 32 are tightly assembled under the lateral clamping force of the clamping component 21, which can effectively resist the expansion force of the molten solder on the parting surface during casting, ensuring that the cavity remains closed during the filling process, thereby obtaining a solder casting with a smooth surface and clear outline.

[0031] Working principle: When in use, the first module 31 and the second module 32 are placed on the device base frame 1, so that the first half cavity 33 and the second half cavity 34 are in the assembled state, together forming a cavity that matches the shape of the drill bit solder. When the first module 31 and the second module 32 are locked in place; The hydraulic cylinder 2101 drives the lower pressure plate 2102 downward, and the lower pressure connecting rod 2104 converts the vertical motion into the horizontal sliding of the translation slider 2106, which drives the clamping plate 2109 to move towards the center of the forming mold 3 simultaneously from four directions, realizing the rapid centering and clamping of the outer contour of the forming mold 3. The clamping force is evenly output in four directions, which fundamentally eliminates the tilting or displacement of the forming mold 3 caused by unilateral load. During the linear movement of the clamping plate 2109 inward, the force-applying end of the clamping rotating plate 2305 installed at the top of the clamping plate 2109 contacts the side end face of the forming mold 3 first before the clamping force. As the clamping plate 2109 continues to advance, the clamping torsion spring 2306 converts the horizontal thrust into a vertical downward preload, so that the forming mold 3 can withstand the lateral clamping force and subsequent casting expansion. Before the molding force is applied, the mold is stably pressed against the working surface of the base frame 1. When the lower pressure plate 2102 continues to descend, the lower vertical rod 2203 drives the lower horizontal rod 2204 and the pressing connecting plate 2205 to move down synchronously, thereby driving the upper horizontal rod 2206 to move the pressing plate 2207. The inclined sliding rod 2202 and the inclined sliding hole 2208 are used to guide the vertical downward pressure into a horizontal and inclined composite motion, so that the pressing plate 2207 moves towards the upper surface of the molding mold 3 and gradually presses it. After the inclined wedge structure is pressed into place, it forms a geometric self-locking tendency. Even if thermal expansion or equipment vibration occurs during the casting process, the pressing force will not decrease or loosen, ensuring that the cavity remains closed throughout the entire cycle of molten solder filling and solidification, and ensuring the effectiveness of the solder casting forming device.
