Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of casting, and in particular relates to an orthopedic device for castings. Background Art
[0002] During the molding process, castings may be partially deformed due to factors such as their own structure, mold temperature, or cooling shrinkage. Due to the structural characteristics and production conditions, the deformation problem cannot be fundamentally solved, so an additional correction process is required to deal with the deformation.
[0003] At present, the existing method of dealing with casting deformation is to add a manual correction process for the upper and lower surfaces of the casting at specific positions after the casting is formed. The main method of manually dealing with casting deformation is to use a wooden hammer to knock the protrusions on the upper and lower surfaces of the product. Due to the instability of the deformation position and deformation amount of the casting, the process is complicated and unstable, and even the casting may be scrapped due to cracks due to uneven force during knocking.

Each lower support column is fixedly inserted in the corresponding lower through hole. Each lower support column and the corresponding upper clamping column are coaxially arranged, and the top surface of each lower support column is at the same height as the upper surface of the convex template at the corresponding position.

[0015] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:
[0016] Regarding the orthopedic device for castings provided in an embodiment of the present invention, when orthopedic treatment is performed on a product, first, the product is placed on a convex plate. At this time, multiple raised areas (deformed areas, see figure) on the lower surface of a specific position of the product are in contact with the top surfaces of some lower support columns. The vertical positions of these raised areas are considered to be the reference plane (i.e., the top surfaces of all lower support columns are located on the reference plane). Other positions on the lower surface of the specific position of the product (i.e., the concave areas on the lower surface of the specific position of the product) are respectively located above other lower support columns. At this time, the distance measuring sensors relative to the other lower support columns collect the distance data between the concave areas on the lower surface of the specific position of the product and the corresponding top surfaces of the other lower support columns (at this time, the reference plane formed by the top surfaces of the multiple lower support columns is the undeformed plane of the lower surface of the specific position of the product, and the plane formed by the bottom surfaces of the multiple upper clamping columns is the undeformed plane of the upper surface of the specific position of the product). Then, the distance measuring sensors relative to the other lower support columns transmit the measured distance data to the controller, and the controller controls the corresponding stepper motor to drive the corresponding upper clamping column to move accordingly and extend the same distance from the concave plate.
[0017] Finally, the lifting device drives the upper die base to descend, and the lower die base drives the concave die plate downward. Since the extended upper clamping column will first act on the raised area of the upper surface of the specific position of the product (corresponding to the concave area of the lower surface of the specific position of the product), these deformed areas can be automatically squeezed. When all the ranging sensors detect that the corresponding positions of the lower surface of the specific position of the product are all reference positions, the controller controls the same stepper motor to drive the corresponding upper clamping column to reset and move up to the initial position, and the lifting device continues to drive the upper die base to keep pressing down for a period of time to avoid resetting the deformed position. At this time, each position of the lower surface of the specific position of the product is exactly at the same height as the top surface of the lower support column, and each position of the upper surface of the specific position of the product is exactly at the same height as the bottom surface of the upper clamping column, thereby conveniently completing the correction of the product with high stability, avoiding the problem of castings being scrapped due to cracks due to uneven force from knocking.
[0018] That is to say, the orthopedic device for castings provided by the embodiment of the present invention can conveniently complete the correction of the product through the die assembly and the orthopedic assembly, and has high stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example:
[0029] Figure 1 FIG. 1 is a schematic structural diagram of a correction device for castings provided by an embodiment of the present invention, as shown in FIG. Figure 1 As shown, the orthopedic device includes a die assembly 1 and an orthopedic assembly 2 .
[0030] The die assembly 1 includes an upper die 11 and a lower die 12. The upper die 11 includes an upper die base 111 and a concave die plate 112 matching the upper surface of the product 100. The upper die base 111 is used to be connected to the lifting equipment for transmission to lift the upper die base 111. The concave die plate 112 is located on the upper die base 111. The concave die plate 112 has a plurality of upper through holes 1121. The lower die 12 includes a lower die base 121 and a convex die plate 122 matching the lower surface of the product 100. The convex die plate 122 is located on the lower die base 121 and directly below the concave die plate 112 to clamp and position the product 100. The convex die plate 122 has a plurality of lower through holes 1221.
[0031] The orthopedic component 2 includes multiple stepper motors 21, multiple upper clamping columns 22, multiple lower support columns 23, multiple distance measuring sensors 24 and a controller 25. The multiple stepper motors 21 are arranged at intervals on the upper mold base 111. The output shaft of each stepper motor 21 is transmission connected to the corresponding upper clamping column 22, and each upper clamping column 22 can be movably inserted in the corresponding upper through hole 1121. Each lower support column 23 is fixedly inserted in the corresponding lower through hole 1221. Each lower support column 23 and the corresponding upper clamping column 22 are coaxially arranged, and the top surface of each lower support column 23 is at the same height as the upper surface of the convex template 122 at the corresponding position. Each distance measuring sensor 24 is located on the corresponding lower support column 23. Each distance measuring sensor 24 and each stepper motor 21 are respectively electrically connected to the controller 25.
[0032] For a correction device for castings provided by an embodiment of the present invention, when correcting a product 100, first, the product 100 is placed on a convex plate 122. At this time, multiple convex areas (deformation areas, see Figure 2) contacts the top surfaces of some lower support columns 23, and the vertical positions of these raised areas are regarded as the reference plane (i.e., the top surfaces of all lower support columns 23 are located on the reference plane). Other positions of the lower surface of the specific position of the product 100 (i.e., the concave areas of the lower surface of the specific position of the product 100) are respectively located above other lower support columns 23. At this time, the distance measuring sensors 24 relative to the other lower support columns 23 collect the distance data between the concave areas of the lower surface of the specific position of the product 100 and the corresponding top surfaces of the other lower support columns 23 (at this time, the reference plane formed by the top surfaces of the multiple lower support columns 23 is the undeformed plane of the lower surface of the specific position of the product 100, and the plane formed by the bottom surfaces of the multiple upper clamping columns 22 is the undeformed plane of the upper surface of the specific position of the product 100). Then, the distance measuring sensors 24 relative to the other lower support columns 23 transmit the measured distance data to the controller 25, and the controller 25 controls the corresponding stepping motor 21 to drive the corresponding upper clamping column 22 to move accordingly and extend the same distance from the concave template 112.
[0033] Finally, the lifting device drives the upper mold base 111 downward, while the lower mold base 121 drives the concave mold plate 112 downward. Since the extended upper compression rod 22 first acts on the raised area on the upper surface of the product 100 at a specific location (corresponding to the concave area on the lower surface of the product 100 at a specific location), these deformed areas can be automatically squeezed. When all the distance measuring sensors 24 detect that the corresponding positions on the lower surface of the product 100 at a specific location are at the reference position, the controller 25 controls the same stepper motor 21 to drive the corresponding upper compression rod 22 to reset and move upward to the initial position. The lifting device continues to drive the upper mold base 111 to maintain downward pressure for a period of time to prevent the deformed position from resetting. At this time, each position of the lower surface of the specific position of the product 100 is exactly at the same height as the top surface of the lower support column 23, and each position of the upper surface of the specific position of the product 100 is exactly at the same height as the bottom surface of the upper clamping column 22, thereby conveniently completing the correction of the product 100 with high stability, and avoiding the problem of casting cracks and other scrapping due to uneven force caused by hammering.
[0034] That is, the orthopedic device for castings provided by the embodiment of the present invention can conveniently complete the correction of the product 100 through the die assembly 1 and the orthopedic assembly 2, and has high stability.
[0035] It should be noted that the correction of product 100 primarily controls deformation at specific locations to meet factory requirements, and the number and location of these specific locations are determined by design requirements. Specifically, this is achieved by positioning the upper compression posts 22 and lower support posts 23 at the upper and lower surfaces of the specific locations on product 100, respectively. Furthermore, during the correction process, the convex and concave templates 122 and 112 align with the surface of product 100, enabling precise positioning of product 100 and preventing lateral movement of product 100 during the correction process.
[0036] Furthermore, when the upper pressing posts 22 are not raised or lowered, the bottom surface thereof is at the same height as the bottom surface of the concave plate 112 at the corresponding position.
[0037] Alternatively, the lifting device can be a die machine, a cylinder, or other lifting structure. The lifting direction of the upper die holder 111 is the same as the axis of the upper pressing column 22 and the axis of the lower support column 23. The upper through hole 1121 is perpendicular to the concave die plate 112, and the lower through hole 1221 is perpendicular to the convex die plate 122.
[0038] Exemplarily, the upper die base 111 and the concave die plate 112 , and the lower die base 121 and the convex die plate 122 are connected by welding, thereby increasing the connection strength between the upper die base 111 and the concave die plate 112 , and between the lower die base 121 and the convex die plate 122 .
[0039] In other embodiments of the present invention, the upper die base 111 and the concave die plate 112 , and the lower die base 121 and the convex die plate 122 may also be connected by bolts, which is not limited by the present invention.
[0040] In this embodiment, the upper mold 11 further includes a first buffer plate 113 , which is located between the upper mold base 111 and the concave mold plate 112 , and the first buffer plate 113 is connected to the upper mold base 111 via a spring, and the concave mold plate 112 is located on the first buffer plate 113 .
[0041] In the above embodiment, the first buffer plate 113 buffers the downward pressure of the concave plate 112 , thereby preventing the concave plate 112 from making hard contact with the product 100 and damaging the product 100 during the downward movement.
[0042] Similarly, lower die 12 also includes a second buffer plate 123, located between lower die base 121 and male die plate 122. Second buffer plate 123 is connected to lower die base 121 via a spring. Male die plate 122 is located on second buffer plate 123, and second buffer plate 123 and first buffer plate 113 are arranged parallel and spaced apart. Therefore, second buffer plate 123 acts as a buffer for male die plate 122, preventing it from making hard contact with product 100 and potentially damaging it.
[0043] In one implementation of the present invention, a plurality of guide posts 124 are fixedly mounted on the lower die base 121 . The plurality of guide posts 124 are arranged in parallel and spaced apart. Each guide post 124 is perpendicular to and passes through the first buffer plate 113 and the second buffer plate 123 .
[0044] In the above embodiment, the guide column 124 guides the lifting and lowering of the first buffer plate 113 and the second buffer plate 123, preventing the first buffer plate 113 or the second buffer plate 123 from moving left and right and affecting the position of the concave template 112 or the convex template 122, thereby avoiding affecting the layout accuracy of the upper clamping column 22 and the lower support column 23, thereby achieving precise positioning of the product 100.
[0045] Illustratively, a plurality of guide sleeves 125 are inserted into the first buffer plate 113 , each guide sleeve 125 is opposite to a corresponding guide post 124 , and each guide post 124 is slidably inserted into a corresponding guide sleeve 125 , thereby preventing the first buffer plate 113 from being worn.
[0046] Furthermore, a limiting block 13 is sandwiched between the first buffer plate 113 and the upper die base 111 , and between the second buffer plate 123 and the lower die base 121 .
[0047] In the above embodiment, the limit block 13 can prevent the spring from being damaged due to excessive compression.
[0048] Exemplarily, the limiting block 13 is fixed to the upper die base 111 or the lower die base 121 by bolts.
[0049] See again Figure 1 The lower die base 121 has a plurality of countersunk holes, each of which is inserted with a fixing block 1211 , and the bottom end of each lower support column 23 is inserted into the fixing block 1211 and threadedly engaged.
[0050] In the above embodiment, the fixing block 1211 can support and position the lower support column 23 .
[0051] In one implementation of the present invention, a plurality of first limiting columns 1111 are installed on the upper mold base 111, and a plurality of second limiting columns 1212 are installed on the lower mold base 121. Each first limiting column 1111 and the corresponding second limiting column 1212 are coaxially arranged, and each first limiting column 1111 or each second limiting column 1212 extends out of the upper mold base 111 or the lower mold base 121.
[0052] In the above embodiment, the first limiting column 1111 and the second limiting column 1212 can offset each other to limit the distance between the upper mold base 111 and the lower mold base 121, thereby preventing the upper mold base 111 from moving downward too far and fracturing the product 100 or the concave mold base 112 and the convex mold base 122.
[0053] For example, the first limiting post 1111 penetrates the first buffer plate 113 with a clearance fit, and the second limiting post 1212 penetrates the second buffer plate 123 with a clearance fit.
[0054] Exemplarily, the first buffer plate 113 and the concave plate 112 , and the second buffer plate 123 and the convex plate 122 are connected by welding.
[0055] The correction device provided by the present invention can accurately and effectively implement the correction process according to the different deformation positions and deformation amounts of each product 100, wherein the collection of real-time data provides effective data support for the correction of the casting.
[0056] It will be easily understood by those skilled in the art that 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, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
