Description

Technical Field

[0001] This application belongs to the field of tooling for the production of bearing cages, and particularly relates to an annealing tooling for cages. Background Art

[0002] During the production process of tapered cages, a key technological process involves annealing treatment, which is crucial for ensuring the dimensional stability, material properties, and final quality of the product. In the production process of some tapered cages, two annealing treatments need to be implemented: the first annealing is carried out for the products with bottoms, and the second annealing is for the cut-bottom products that have completed bottom cutting.

[0003] However, for the annealing treatments of these two different states, the existing tooling designs have obvious limitations. In the first annealing stage, the existing tooling can better meet the needs of products with bottoms. The products with bottoms can be directly stacked on the tooling. But when performing the second annealing, that is, when processing the cut-bottom products, if the first annealing tooling is still used and the products are directly stacked, contact will occur between the products. Especially, the small-end ring of the upper cage is likely to enter the large-end ring of the lower cage, forming an overlapping area. This overlap not only seriously hinders the uniform heat transfer and affects the annealing effect, but also may have an adverse impact on the structural integrity and performance of the cage. In addition, the existing tooling requires workers to load the products one by one from the top of the tooling. This process is not only cumbersome and inefficient, but also increases the manual labor intensity, which is not conducive to the improvement of production efficiency and personnel safety. Therefore, there is an urgent need for a more efficient, convenient, and annealing-quality-guaranteed tooling design to meet the annealing requirements of tapered cages in different states, optimize the production process, and improve production efficiency and product quality. Thus, the existing technology needs to be further improved and enhanced. Summary of the Utility Model

[0004] The utility model provides an annealing tooling for cages, which can adapt to different states, and the tooling design for cages with bottoms and cut-bottom tapered cages is convenient for loading and unloading products from the side of the tooling, so as to reduce the cumbersome operation and labor intensity of operating one by one from the top and improve production efficiency.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] An annealing tooling for cages includes a bearing base, a lifting frame, and multiple columns between the two. The columns are evenly arranged around the edge of the bearing base. The three together enclose an internal space for accommodating the cage products with bottoms. A plurality of support holes are evenly distributed along the length direction of the columns. Support elements are detachably inserted into the support holes to support the cut-bottom products, so as to keep a gap between adjacent cut-bottom products and meet the process requirements of the two production stages of the tapered cage annealing process.

[0007] The cage annealing tooling of the present application can adapt to cage products in two different states, namely products with bottoms and products with cut bottoms, through detachable and pluggable support elements. When annealing products with bottoms, the support elements can be removed, and the space enclosed by the bearing base and the upright columns can be directly used for annealing; while when annealing products with cut bottoms, the support elements are inserted to maintain the interval between products. The insertion of the support elements ensures that the products with cut bottoms do not contact or overlap with each other during the annealing process, thus avoiding uneven heat transfer. Each product can obtain sufficient heat, ensuring the uniformity of the annealing effect, and further improving the quality and performance of the products. A plurality of support holes are evenly distributed along the length direction of the upright columns, enabling workers to quickly and accurately insert or remove the support elements to adapt to different annealing stages. This reduces the production time and improves the production efficiency.

[0008] In a preferred implementation, the upright column includes a fixed upright column and a movable upright column. One end of the fixed upright column is fixedly connected to the bearing base, and the other end is detachably connected to the lifting frame. Both ends of the movable upright column are respectively detachably connected to the bearing base and the lifting frame. Removing the movable upright column can open the side space to place the cage product from the side.

[0009] For cages that are difficult to operate from above due to their size, shape or weight, by removing the movable upright column, the side space of the tooling can be opened, which makes it easier to place and remove the cage product from the side. The openness of the side space simplifies the loading and unloading processes, reduces the operation time, and thus improves the production efficiency.

[0010] In a preferred implementation, the bearing base is provided with a sleeve, and a lateral mounting hole is opened in the sleeve. One end of the movable upright column is provided with a connection hole, and a bolt passes through the mounting hole and the connection hole to connect the movable upright column and the bearing base.

[0011] By passing a bolt through the mounting hole of the sleeve and the connection hole of the movable upright column, the detachable connection between the movable upright column and the bearing base can be conveniently achieved. When the movable upright column needs to be removed to open the side space, the operation becomes simple and fast.

[0012] In a preferred implementation, the bearing base includes an outer ring, and a plurality of cross - arranged reinforcing ribs are provided inside the outer ring. The reinforcing ribs are perpendicular to the upright columns.

[0013] In a preferred implementation, the bearing base is hexagonal or circular.

[0014] In a preferred implementation, the lifting frame includes multiple horizontal plates. The multiple horizontal plates are located in the same plane and are arranged crosswise. Each horizontal plate is connected to two columns. The horizontal plate is provided with socket holes, and the diameter of the socket holes is greater than or equal to the diameter of the columns. The end of the column is provided with two fixing holes, and the distance between the two fixing holes is adapted to the thickness of the horizontal plate. Fixing members are arranged in the fixing holes to prevent the lifting frame from detaching from the columns.

[0015] In a preferred implementation, a hook member is arranged at the cross position of the horizontal plates to connect the lifting lock.

[0016] In a preferred implementation, the hook member is arched.

[0017] In a preferred implementation, the movable column is arranged at the center of the bearing base. The movable column at the center and the columns at the outer edge divide the internal space into intervals adapted to cage products of different sizes to meet the support requirements of cage products of different sizes.

[0018] Through the ingenious layout of the central movable column and the outer-edge columns, multiple intervals of different sizes can be flexibly divided to adapt to cage products of various sizes. This design maximally utilizes the space inside the tooling, improving the versatility and flexibility of the tooling. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0028] In the present invention, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present invention, descriptions such as "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one of such features.

[0030] The present invention will be described below in conjunction with the accompanying drawings of the specification.

[0031] The specific solution adopted is:

[0032] As shown Figures 1-4 in the figure, the present utility model provides a cage annealing tooling, which includes a bearing base 1, a hoisting frame 2 and multiple columns 3 between the two. The columns are evenly arranged around the edge of the bearing base. The three jointly enclose an internal space for accommodating the cage products with bottoms. A plurality of support holes 32 are evenly distributed along the length direction of the columns. Support elements 4 are detachably inserted into the support holes to support the bottom-cut products, so that there is a gap between adjacent bottom-cut products, meeting the process requirements of two production stages of the tapered cage annealing process.

[0033] The cage annealing tooling of the present application can easily adapt to cage products in two different states, namely products with bottoms and bottom-cut products, through the detachably inserted support elements 4. When annealing the products with bottoms, the support elements can be removed, and the space enclosed by the bearing base 1 and the columns 3 can be directly used for annealing; when annealing the bottom-cut products, the support elements are inserted to keep the intervals between the products. The insertion of the support elements ensures that the bottom-cut products do not contact or overlap each other during the annealing process, thus avoiding uneven heat transfer. Each product can obtain sufficient heat, ensuring the uniformity of the annealing effect, and further improving the quality and performance of the products. The multiple support holes evenly distributed along the length direction of the columns allow workers to select appropriate support holes to insert the support elements according to different annealing requirements and product specifications. This design provides flexibility, enabling the tooling to be applicable to cage products of different sizes and shapes. Workers can quickly and accurately insert or remove the support elements to adapt to different annealing stages. This reduces the production time and improves the production efficiency. There is no need to purchase different tooling equipment for each product separately. This reduces the production cost and improves the economic benefits of the enterprise.

[0034] As a preferred embodiment of the present application, the column includes a fixed column 30 and a movable column 31. One end of the fixed column is fixedly connected to the bearing base, and the other end is detachably connected to the hoisting frame. Both ends of the movable column are respectively detachably connected to the bearing base and the hoisting frame. Removing the movable column can open the side space to place the cage products from the side.

[0035] By disassembling the movable column, the side space of the tooling can be opened, which makes it easier to place and remove the cage products from the side. The openness of the side space simplifies the loading and unloading process, reduces the operation time, and thus improves the production efficiency. Workers can place and remove the cage products faster, reducing the idle time in the production cycle. This is a significant advantage for cages that are difficult to operate from above due to their size, shape, or weight. The combination of the fixed column and the movable column allows the tooling to adapt to cage products of different sizes and shapes. By adjusting the position or number of the movable columns, the size and shape of the internal space can be easily changed to meet the annealing requirements of specific products.

[0036] See Figure 1 and Figure 2 , the bearing base is provided with a sleeve 10, and the sleeve is provided with a lateral mounting hole. One end of the movable column is provided with a connection hole 310, and a bolt 33 passes through the mounting hole and the connection hole to connect the movable column 31 and the bearing base 1.

[0037] By passing a bolt through the mounting hole of the sleeve and the connection hole of the movable column, the detachable connection between the movable column and the bearing base can be conveniently realized. When the movable column needs to be disassembled to open the side space, the operation becomes simple and fast.

[0038] See Figure 1 and Figure 3 , the bearing base 1 includes an outer ring 11, and a plurality of cross - arranged reinforcing ribs 12 are provided inside the outer ring. The reinforcing ribs are perpendicular to the column 3. The arrangement of the reinforcing ribs effectively increases the rigidity and strength of the bearing base, enabling it to withstand greater weight and stress. This ensures that the bearing base 1 can maintain stable support performance even during the annealing process under high temperature and heavy load. The reinforcing ribs are perpendicular to the column, forming a stable support structure with the column and enhancing the overall stability of the tooling.

[0039] As a preferred embodiment of the present application, the bearing base is hexagonal or circular. Columns can be arranged at the six corners of the hexagonal base or in the same annular area of the circular base, which can ensure uniform support for the cage products during the annealing process, enabling each column to effectively share the weight and stress.

[0040] As a preferred embodiment of the present application, the lifting frame 2 includes multiple horizontal plates 20. The multiple horizontal plates are located in the same plane and intersect with each other, enhancing the overall rigidity and stability of the lifting frame. The intersecting structure can effectively disperse the weight and stress, preventing the lifting frame from deforming or being damaged during the lifting process. Each horizontal plate is connected to two columns, further enhancing the structural strength of the lifting frame. The columns, as the main supporting components, are tightly connected to the horizontal plates, forming a stable framework. The horizontal plates are provided with socket holes 200, the diameter of which is greater than or equal to the diameter of the columns. The columns can be easily inserted into the socket holes, simplifying the installation process. The ends of the columns are provided with two fixing holes 300, and the distance between the two fixing holes is adapted to the thickness of the horizontal plates. Fixing members such as bolts are arranged in the fixing holes to prevent the lifting frame 2 from detaching from the columns. Through a reasonable structural layout and a stable connection method, it is ensured that the lifting frame can maintain balance and stability during the lifting process, avoiding accidents.

[0041] As a preferred embodiment of the present application, refer to Figure 1 , a hook member 21 is arranged at the intersecting position of the horizontal plates to connect the lifting lock. The hook member is in an arch shape. The hook member, as the connecting component between the lifting frame and the lifting lock, undertakes the important task of transmitting the lifting force from the lifting lock to the lifting frame. Its design needs to ensure firm and reliable connection and can withstand various forces and torques during the lifting process. Arranging the hook member at the intersecting position of the horizontal plates is beneficial to realizing the uniform distribution of the lifting force and preventing the lifting frame from tilting or twisting.

[0042] As a preferred embodiment of the present application, refer to Figure 4 , the movable column is arranged at the center of the bearing base. The movable column at the center and the columns at the outer edge divide the internal space into intervals adapted to cage products of different sizes to meet the support requirements of cage products of different sizes.

[0043] Through the ingenious layout of the movable column at the center and the columns at the outer edge, multiple intervals of different sizes can be flexibly divided to adapt to cage products of various sizes. This design maximally utilizes the space inside the tooling, improving the versatility and flexibility of the tooling.

[0044] In the present utility model, the parts not described can be realized by adopting or referring to the existing technologies.

[0045] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the present utility model can easily think of various changes or substitutions within the technical scope disclosed by the present utility model, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
