Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a wheel seat ring suitable for use under low temperature conditions. Background Art
[0002] At present, there are two methods for processing seat rings for wheels larger than 33 inches that are suitable for low-temperature environments. The first method is to use ring forgings for machining. This method has a low material utilization rate, accounting for 24% of the raw materials, wasting raw materials, a large amount of machining, and low processing efficiency; the second method is to use thick steel plates for hot pressing and then machining. The processing process is flame cutting, rolling, rounding, welding, grinding welds, hot pressing, machining and other processes. Welding is prone to welding defects such as pores, and the welding quality cannot be guaranteed; the material utilization rate of thick steel plates is only 40% of the raw materials, and the material utilization rate is low. Because thick steel plates need to be heated in a medium-frequency furnace and then pressed into shape, the power consumption is high and the processing cost is high; the processing allowance is large, the processing efficiency is low, and the machining process becomes a bottleneck process.
[0003] In the production of wheel rims suitable for low-temperature environments by turning ring forgings and hot-pressing thick steel plates, the material utilization rate is generally too low, resulting in material waste and increased production costs. Therefore, the utility model provides a wheel rim suitable for low-temperature conditions to meet the demand. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a wheel seat ring suitable for use under low temperature conditions, so as to solve the problem that the existing technology mostly adopts turning of ring forgings and turning after hot pressing of thick steel plates for production in actual work, resulting in generally too low material utilization rate, resulting in waste of materials and increasing production costs.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0006] A wheel seat ring suitable for use under low temperature conditions, the profile of the seat ring includes a head at one end, a middle section in the middle and a tail at the other end, the head, the middle section and the tail are an integrated structure; the outer surface of the middle section is provided with knurled teeth around the position close to the head.
[0007] Optionally, a stepped groove is provided on the outer side of the head near one end of the middle section.
[0008] Optionally, the middle section is connected to the head at an angle α.
[0009] Optionally, an inner groove is provided on the inner side of the middle section.
[0010] Optionally, there is an arc transition between the outer side of the tail and the middle section.
[0011] Optionally, a groove is provided on the outer side of the tail away from one end of the middle section.
[0012] Optionally, the medial side of the tail is horizontal.
[0013] Optionally, the outer side and the inner side of the head away from one end of the middle section are both curved surfaces.
[0014] Compared with the prior art, the utility model has at least the following beneficial effects:
[0015] In the above scheme, by setting the head, middle section and tail, the thickness of the head is larger, which increases the structural strength of the seat ring; the thickness of the middle section is reduced, the material distribution is optimized, and the waste of material is avoided. The angle α between the head and the middle section is adapted to the tire; the inner side of the tail is horizontally set, and the arc transition design of the angle α with the middle section facilitates the loading and unloading of the tire; the structural strength is enhanced, the redundant material part is reduced, and the stability of the device is increased. The integrated design of the head, middle section and tail makes the structure of the steel section for the entire wheel more compact, reduces the structural materials, and increases the material utilization rate to more than 95%.
[0016] By opening a stepped groove on the outside of the head, there is no need to process the prying edge, which reduces the processing steps and the processing difficulty. By opening an inner groove on the inner side of the middle section, the thickness of the material is reduced through reasonable layout, which further saves materials and reduces material costs. By opening a bevel on the outside of the tail, it is easy to weld with the cylinder and ensure that the welding material flows better and fills into the weld, thereby avoiding the occurrence of welding defects. This not only improves the quality of the welded joint, but also reduces the error rate that may occur during the welding process, thereby improving the welding efficiency.

[0024] The following is a detailed description of a wheel seat ring suitable for low temperature conditions provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.
[0025] It should be noted that the references to "one embodiment", "an embodiment", "an exemplary embodiment", "some embodiments" and the like in the specification indicate that the embodiments described may include specific features, structures or characteristics, but not every embodiment may include the specific features, structures or characteristics. In addition, when a specific feature, structure or characteristic is described in conjunction with an embodiment, it should be within the knowledge of a person skilled in the art to implement such feature, structure or characteristic in conjunction with other embodiments (whether or not explicitly described).
[0026] In general, a term can be understood, at least in part, from its use in context. For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.
[0027] It is to be understood that the meanings of “on,” “over,” and “above” in the present invention should be interpreted in the broadest manner, so that “on” not only means “directly on” something, but also includes the meaning of being “on” something with intervening features or layers, and “on” or “above” not only means “on” or “above” something, but also includes the meaning of being “on” or “above” something with no intervening features or layers.
[0028] Additionally, spatially relative terms such as "under," "beneath," "lower," "above," "upper," and the like may be used herein for descriptive convenience to describe the relationship of one element or feature to another element or features, as shown in the accompanying drawings.

[0029] like Figures 1 to 3 As shown, an embodiment of the utility model provides a wheel seat ring suitable for use under low temperature conditions, the surface of the seat ring 1 includes a head 2 at one end, a middle section 3 in the middle and a tail 4 at the other end, the head 2, the middle section 3 and the tail 4 are an integrated structure, a step groove 5 is provided on the outer side of the head 2 near one end of the middle section 3, and knurled teeth 8 are provided around the outer surface of the middle section 3 near the head 2. It should be noted here that the outer surface refers to the surface that cooperates with the tire, and by providing the knurled teeth 8, the friction between the tire and the knurled teeth 8 can be increased, and the effect of the tire being limited can be further improved to prevent the tire from slipping.
[0030] The seat ring 1 is made of Q355E steel billet suitable for low temperature of -40℃, and is manufactured through processes such as billet blanking, heating, steel section rolling, straightening, multiple-size sawing, curling, shaping, spot welding, flash butt welding, slag scraping, stress relief annealing, expansion, shrinkage, and turning. The knurled teeth are directly rolled out during steel section rolling, which reduces the knurling process in the subsequent fixed seat ring manufacturing process and improves the processing efficiency. The annealing temperature of the stress relief annealing treatment after welding is 600℃~640℃, and the temperature is kept for two hours, and the heating and cooling speed is 125℃ / hour, which effectively improves the internal structure and avoids the brittle cracking of the weld. Through the design of the stepped groove 5, while increasing the strength of the head 2, in the process of making the wheel accessory fixed seat ring, there is no need to process the prying mouth, which reduces the processing steps and improves the processing efficiency. The thickness of the middle section 3 is reduced, which reduces the weight of the material and saves the material cost.
[0031] like Figure 2 As shown, the middle section 3 is connected to the head 2 at an angle α, an inner groove 6 is provided on the inner side of the middle section 3, an arc transition is formed between the outer side of the tail 4 and the α-angle inclined surface of the middle section 3, and the outer side and the inner side of the head 2 away from the middle section 3 are both arc surfaces.
[0032] The arc transition between the tail 4 and the middle section 3 facilitates the loading and unloading of the tire on the outside of the seat rim 1, reduces the difficulty of work and improves work efficiency. The integrated design of the head, middle section and tail makes the structure of the entire wheel steel more compact, enhances the structural strength, reduces the redundant part of materials, and increases the stability of the device.
[0033] like Figure 2 As shown, the tail portion 4 is horizontal, which is convenient for docking with the cylinder during assembly, and the inner and outer sides of the tail portion 4 away from the middle section 3 are both provided with grooves 7.
[0034] By setting the groove 7, the connection between the cylinder and the seat ring 1 can be better welded to ensure that the molten metal can fully fill the weld during welding, forming a uniform and dense weld joint, forming a solid welding structure, and greatly enhancing the stability of the device.
[0035] Use the corresponding mold to place the cylinder on the side of the tail 4 of the seat ring 1 so that the cylinder and the seat ring 1 fit tightly. Use the welding process to weld the cylinder and the seat ring 1 to ensure a firm connection and complete the splicing of the device.
[0036] The above cylinder is disclosed in the prior art in the present utility model and will not be described in detail here.
[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiment of the present invention, and the present invention can be fully understood by those skilled in the art without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
