Description

Technical Field

[0001] This invention relates to the field of casting equipment technology, and more specifically to a heat-resistant and wear-resistant casting workbench. Background Technology

[0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Because the molding materials used in sand casting are inexpensive and readily available, and the mold manufacturing is simple, it can adapt to single-piece production, batch production, and mass production of castings. For a long time, it has been a basic process in casting production. The casting workbench plays multiple functions and roles in the casting process, including providing stable support for the mold and sand box, ensuring precise alignment of the mold and sand box, and facilitating mold assembly, pouring, cooling, and cleaning by workers.

[0003] Insufficient technology: Traditional workbenches are mostly made of ordinary steel or cast iron. When exposed to high temperatures for a long time, they are prone to thermal deformation, which affects the flatness of the work surface and the positioning accuracy of the mold. At the same time, repeated heating and cooling can also lead to thermal fatigue of the material, resulting in cracks and reducing the structural strength. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heat-resistant and wear-resistant casting worktable to solve the problems existing in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat-resistant and wear-resistant casting workbench, comprising a workbench surface, a base at the bottom of the workbench surface, positioning mechanisms fixedly connected to the four corners of the top of the workbench surface, clamping mechanisms on both sides of the workbench surface, and a cooling mechanism inside the workbench surface. The workbench surface comprises a surface layer, a load-bearing layer, corner supports, and a support frame, wherein the surface layer, load-bearing layer, and support frame are fixedly connected sequentially from top to bottom, and their length and width dimensions are consistent. In addition, corner supports are fixedly connected to the four corner edges of the surface layer and the load-bearing layer. The load-bearing layer comprises an upper load-bearing layer and a lower load-bearing layer. A locking block is fixedly connected to the four corners of the bottom of the upper load-bearing layer, and a locking groove is formed at the four corners of the top of the lower load-bearing layer. The locking block and the locking groove are in the same position and size. The upper load-bearing layer and the lower load-bearing layer are aligned and closed by their locking mechanism. A pipe groove is formed on the contact surface of the upper load-bearing layer and the lower load-bearing layer, and the pipe groove is used to place the cooling pipes of the cooling mechanism.

[0006] Furthermore, the surface layer is made of heat-resistant alloy steel, which can withstand high temperatures and maintain strength when in direct contact with high-temperature metals. The load-bearing layer is made of high-temperature resistant fiberboard, which mainly functions to transmit loads and distribute stress, while providing thermal insulation to reduce heat transfer to the support frame and prevent deformation caused by thermal expansion. The support frame is formed by interlacing longitudinal and transverse steel frames with reserved gaps for thermal expansion in the middle.

[0007] Furthermore, a serpentine cooling pipe is embedded inside the load-bearing layer. The cooling pipe is made of corrosion-resistant stainless steel. The circulating cooling water inside the pipe carries away the heat that the surface layer bears and transfers to the load-bearing layer. In addition, the cooling pipe is fixedly connected to an external pipe on one side of the load-bearing layer through a pipe joint. One end of the external pipe is fixedly connected to a circulation pump body. The pumping power of the circulation pump body is provided by a fourth motor at its top. The circulation pump body and the fourth motor together constitute the circulation pump. One end of the circulation pump body is fixedly connected to a water tank through a connecting pipe one. The other side of the water tank is fixedly connected to a radiator through a connecting pipe two. The top of the radiator is fixedly connected to one end of the cooling pipe.

[0008] Furthermore, the circulating pump body and the fourth motor are located on the front side of the workbench, the water tank is adjacent to the clamping mechanism, and the second connecting pipe, which is fixedly connected to the bottom of one side of the water tank, passes through the bottom of the base and is fixedly connected to the bottom side of the radiator located on the rear side of the workbench.

[0009] Furthermore, a first motor is fixedly connected to the four corners of the top of the surface layer. A push rod is movably connected to the side of the first motor. One end of the push rod passes through the cover plate and is fixedly connected to a movable sleeve. A first fixed rod is movably connected inside the movable sleeve. The two ends of the first fixed rod are fixedly connected to the inside of the connecting plate. The connecting plate is composed of two parallel teardrop-shaped plates. A second fixed rod is inserted through the middle of the plate. The two ends of the second fixed rod are fixedly connected to positioning sleeves through the connecting plate. The top end extends upward and continues to penetrate the cover plate to be fixedly connected to an end cap. The bottom end extends downward and is fixedly connected to the top of the surface layer. A third fixed rod is inserted through the larger end of the teardrop shape of the connecting plate. A positioning wheel is movably connected between the two plates of the connecting plate on the side of the third fixed rod. The second fixed rod acts as a fulcrum and forms a lever with the connecting plate. The first motor controls the push rod to apply force to the smaller end of the teardrop shape of the connecting plate, thereby controlling the displacement of the positioning wheel located at the larger end of the teardrop shape of the connecting plate.

[0010] Furthermore, the clamping mechanism includes a vertically arranged column located on one side of the worktable. A second motor is fixedly connected to the top of the column. A sliding groove is formed at the bottom of the second motor and on the side of the column near the worktable, and a screw is movably connected inside the groove. The top of the screw is movably fixedly connected to the bottom of the second motor. A slider is movably connected to the side of the screw. A third motor is fixedly connected to the side of the slider. A cylinder is movably connected to the side of the third motor. A telescopic rod is movably connected to the side of the cylinder. A clamping block is fixedly connected to one end of the telescopic rod.

[0011] Furthermore, the clamping mechanism is symmetrical about the center line of the worktable, and the two sides of the mechanism move synchronously and symmetrically to fix the mold and sand box and prevent movement or loosening.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. This invention sets the work surface in three layers: surface layer, load-bearing layer, and supporting frame. The surface layer is made of heat-resistant alloy steel, and the load-bearing layer is made of high-temperature resistant fiberboard. In addition to using heat-resistant and wear-resistant materials, it ensures sufficient thickness to withstand high temperature and mechanical load, which helps to increase the overall heat resistance and wear resistance of the work surface.

[0014] 2. This invention designs the supporting frame as a grid-shaped steel frame to bear the overall structure, disperse the load on the workbench and reduce local stress concentration, which helps to avoid structural fracture, prevent structural deformation, and increase the overall strength and resistance to deformation.

[0015] 3. This invention reduces the temperature of the work surface by embedding cooling pipes in the load-bearing layer and using circulating cooling water to remove heat, thus maintaining the work surface temperature within the material's safe range and increasing the heat resistance of the work surface.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The heat-resistant and wear-resistant casting workbench of the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Figures 1 to 3This invention provides a heat-resistant and wear-resistant casting workbench, including a workbench surface 1, a base 2 at the bottom of the workbench surface 1, positioning mechanisms 3 fixedly connected to the four corners of the top of the workbench surface 1, clamping mechanisms 4 on both sides of the workbench surface 1, and a cooling mechanism 5 inside the workbench surface 1. The workbench surface 1 includes a surface layer 101, a load-bearing layer 102, corner supports 103, and a support frame 104, wherein the surface layer 101, the load-bearing layer 102, and the support frame 104 are fixedly connected from top to bottom, and their length and width dimensions are the same. In addition, the four corner edges of the surface layer 101 and the load-bearing layer 102 are... Angle bracket 103 is fixedly connected. The load-bearing layer 102 includes an upper load-bearing layer 1021 and a lower load-bearing layer 1022. The bottom four corners of the upper load-bearing layer 1021 are fixedly connected with locking blocks 1024. The top four corners of the lower load-bearing layer 1022 are provided with locking slots 1025. The locking blocks 1024 and the locking slots 1025 are in the same position and size. The upper load-bearing layer 1021 and the lower load-bearing layer 1022 are aligned and closed by locking the two. The contact surface of the upper load-bearing layer 1021 and the lower load-bearing layer 1022 is provided with a pipe groove 1023. The pipe groove 1023 is used to place the cooling pipe 501 of the cooling mechanism 5.

[0026] The surface layer 101 is made of heat-resistant alloy steel, which can withstand high temperatures and maintain strength when in direct contact with high-temperature metals. The load-bearing layer 102 is made of high-temperature resistant fiberboard, which mainly transmits loads and disperses stress, while providing thermal insulation to reduce the transfer of heat to the support frame 104 and prevent thermal expansion from causing deformation. The support frame 104 is formed by the interlacing of longitudinal and transverse steel frames, with reserved thermal expansion gaps in the middle.

[0027] In this embodiment, the workbench 1 is composed of three layers: a surface layer 101, a load-bearing layer 102, and a support frame 104. The surface layer 101 is made of heat-resistant alloy steel, the load-bearing layer 102 is made of high-temperature resistant fiberboard, and the support frame 104 is formed by interlacing longitudinal and transverse steel frames. In addition to using heat-resistant and wear-resistant materials, it ensures sufficient thickness to withstand high temperatures and mechanical loads. Furthermore, the longitudinal and transverse steel frame design of the support frame 104 increases the overall resistance to deformation. In actual use of the workbench, the surface layer 101 directly contacts high-temperature metal or molds, the load-bearing layer 102 transmits loads and disperses stress while providing thermal insulation, and the support frame 104 supports the overall structure and prevents deformation. In addition, this embodiment also embeds cooling pipes 501 in the load-bearing layer 102 to reduce the temperature of the workbench 1.

[0028] Reference Figures 3 to 4The load-bearing layer 102 has an embedded serpentine cooling pipe 501. The cooling pipe 501 is made of corrosion-resistant stainless steel. The circulating cooling water inside carries away the heat that the surface layer 101 bears and transfers to the load-bearing layer 102. In addition, the cooling pipe 501 is fixedly connected to an external pipe 503 on one side of the load-bearing layer 102 through a pipe joint 502. One end of the external pipe 503 is fixedly connected to a circulation pump body 504. The pumping power of the circulation pump body 504 is provided by a fourth motor 505 at its top. The circulation pump body 504 and the fourth motor 505 together constitute the circulation pump. One end of the circulation pump body 504 is fixedly connected to a water tank 507 through a connecting pipe 1 506. The other side of the water tank 507 is fixedly connected to a radiator 509 through a connecting pipe 2 508. The top of the radiator 509 is fixedly connected to one end of the cooling pipe 501.

[0029] The circulating pump body 504 and the fourth motor 505 are located on the front side of the workbench 1. The water tank 507 is adjacent to the clamping mechanism 4. In addition, the connecting pipe 508, which is fixedly connected to the bottom of one side of the water tank 507, passes through the bottom of the base 2 and is fixedly connected to the bottom side of the radiator 509 located on the rear side of the workbench 1.

[0030] In this embodiment, the serpentine cooling pipe 501 is embedded in the load-bearing layer 102 of the workbench 1, which avoids direct contact with high temperature and also reduces the temperature of the surface layer 101. The circulating pump body 504 and the fourth motor 505 together form a circulating pump to provide cooling water circulation power. The radiator 509 is responsible for dissipating heat from the cooling water. The water tank 507 is responsible for storing cooling water and buffering temperature fluctuations. The pipes are responsible for connecting the various components of the cooling mechanism 5. The circulating pump body 504 and the fourth motor 505, the water tank 507 and the radiator 509 are arranged around the workbench 1, which can reduce the pipe length and reduce the pressure drop.

[0031] Reference Figures 5 to 6A first motor 301 is fixedly connected to the four corners of the top of the surface layer 101. A push rod 302 is movably connected to the side of the first motor 301. One end of the push rod 302 passes through the cover plate 303 and is fixedly connected to a movable sleeve 304. A first fixed rod 305 is movably connected inside the movable sleeve 304. The two ends of the first fixed rod 305 are fixedly connected to the inside of the connecting plate 306. The connecting plate 306 is composed of two parallel teardrop-shaped plates. A second fixed rod 3061 is inserted through the middle of the plate. The two ends of the second fixed rod 3061 pass through the connecting plate 306 and are fixedly connected to positioning sleeves 3062, with the top end facing upwards. An end cap 3063 is fixedly connected to the cover plate 303 and extends downward to be fixedly connected to the top of the surface layer 101. A third fixing rod 3064 is provided through the teardrop-shaped large end of the connecting plate 306. A positioning wheel 3065 is movably connected between the two plates of the connecting plate 306 on the side of the third fixing rod 3064. The second fixing rod 3061 serves as a fulcrum and forms a lever with the connecting plate 306. The first motor 301 controls the push rod 302 to apply force to the teardrop-shaped small end of the connecting plate 306, which can control the displacement of the positioning wheel 3065 located at the teardrop-shaped large end of the connecting plate 306.

[0032] In this embodiment, the first motor 301 controls the push rod 302 to extend towards the cover plate 303 and apply force to one end of the connecting plate 306. This end rotates around the second fixed rod 3061 away from the first motor 301, while the other end of the connecting plate 306 rotates around the second fixed rod 3061 towards the first motor 301. That is, the positioning wheel 3065 moves inward towards the cover plate 303. Conversely, the retraction movement of the push rod 302 towards the first motor 301 will cause the positioning wheel 3065 to move outward towards the cover plate 303. By setting the first motor 301 at the top four corners of the surface layer 101 so that it can accurately control the extension and retraction of the positioning wheel 3065, the position of the mold and the sand box can be precisely adjusted.

[0033] Reference Figure 1 and Figure 7 The clamping mechanism 4 includes a vertical column 401 located on one side of the worktable 1. A second motor 402 is fixedly connected to the top of the column 401. A sliding groove 404 is provided on the bottom of the second motor 402 and on the side of the column 401 near the worktable 1. A screw 403 is movably connected inside the groove. The top of the screw 403 is movably fixedly connected to the bottom of the second motor 402. A slider 405 is movably connected to the side of the screw 403. A third motor 406 is fixedly connected to the side of the slider 405. A cylinder 407 is movably connected to the side of the third motor 406. A telescopic rod 408 is movably connected to the side of the cylinder 407. A clamping block 409 is fixedly connected to one end of the telescopic rod 408.

[0034] Among them, the clamping mechanism 4 is symmetrical about the center line of the worktable 1, and the two sides of the mechanism move synchronously and symmetrically to fix the mold and sand box and prevent movement or loosening.

[0035] In this embodiment, the second motor 402 drives the screw 403 to rotate, which causes the slider 405 to move up and down, thereby driving the third motor 406, cylinder 407, telescopic rod 408, and clamping block 409 to move up and down as a whole. The third motor 406 can drive the cylinder 407, telescopic rod 408, and clamping block 409 to rotate as a whole. The cylinder 407 controls the extension and retraction of the telescopic rod 408. When the telescopic rods 408 on both sides of the worktable 1 extend at the same time, the clamping block 409 at the top of them will clamp and fix the sand box from both sides. When the telescopic rods 408 on both sides of the worktable 1 retract at the same time, the fixed state of the clamping mechanism 4 can be released.

[0036] The working principle of this invention is as follows: During the casting process, the worker places the mold on the surface layer 101 and places the sand box. The positioning mechanism 3, which is fixedly connected to the four corners of the top of the worktable 1, calibrates the position of the sand box to ensure that the mold and the sand box are precisely aligned, so as to ensure the accuracy of the size and shape of the casting. Then, the worker begins to perform operations such as mold assembly and filling of casting sand on the worktable. The clamping mechanism 4 is then used to fix the sand box to prevent displacement caused by vibration or impact of molten metal during pouring. The next step is to pour the casting and cool it with the assistance of the cooling mechanism 5. Finally, the clamping control of the clamping mechanism 4 is released, the mold is removed, the mold is opened, and the casting is taken out.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
