Description

An adjustable steel cutting mechanism for hot cutting bearing segments Technical Field

[0001] This utility model relates to the field of bearing material processing technology, specifically to an adjustable bearing material hot cutting steel cutting mechanism. Background Technology

[0002] In the bearing manufacturing industry, hot cutting of bearing segments is one of the key processing steps, and its cutting accuracy and quality directly affect the subsequent processing and final performance of the bearing. With the manufacturing industry's increasing demands for bearing product quality and processing efficiency, the steel cutting mechanism, as the core equipment for hot cutting bearing segments, requires particularly important optimization and improvement in performance.

[0003] Traditional steel cutting mechanisms typically consist of a bottom template and an upper template. The bottom template has a bottom mold base for the round steel to pass through in a directional manner, while the upper template has an upper mold base on its bottom surface, on which the steel cutting blade is mounted. The lack of a precise positioning structure makes it difficult to accurately control the position of the round steel during cutting, resulting in large dimensional deviations in the cut segments and failing to meet the requirements of high-precision processing. Furthermore, it increases the difficulty of operation and the time required for setup. Summary of the Invention

[0004] This invention provides an adjustable steel cutting mechanism for hot cutting of bearing segments, which solves the technical problems in the prior art that make positioning and cutting inconvenient and affect accuracy and processing efficiency.

[0005] To solve the above problems, the present invention provides an adjustable bearing material hot-cutting steel breaking mechanism with the following technical solution:

[0006] It includes a bottom template and an upper template. The bottom template is provided with a bottom mold base for the directional passage of round steel. The bottom surface of the upper template is provided with an upper mold base. The upper mold base is provided with a steel cutting blade. The bottom template is provided with a positioning component that is spaced apart from the bottom mold base. The positioning component includes a positioning seat and a positioning rod that is laterally adjustable on the positioning seat.

[0007] The upper mold base is provided with a slot for installing the steel cutting blade on the side close to the bottom mold base, and the upper mold base is provided with clearance grooves distributed opposite to the positioning rod.

[0008] The bottom mold base is equipped with a steel cutting blade cylinder, and the first end of the steel cutting blade cylinder, which is close to the steel cutting blade, extends out of the bottom mold base.

[0009] Furthermore, the upper side of the steel-breaking blade abuts against the upper side wall of the slot, the lower side of the steel-breaking blade abuts against the lower side wall of the slot, and the depth of the slot is less than the thickness of the steel-breaking blade.

[0010] Furthermore, the steel cutting blade is detachably mounted in the slot by bolts, the upper mold base is provided with a through hole for mounting the steel cutting blade, and the steel cutting blade is provided with a countersunk hole corresponding to the through hole.

[0011] Furthermore, the positioning seat is provided with a threaded seat sleeve, and the positioning rod is a lead screw that fits through the threaded seat sleeve.

[0012] Furthermore, the threaded seat includes an auxiliary connecting section and a fixed connecting section. The diameter of the auxiliary connecting section is smaller than the diameter of the fixed connecting section, and a limiting shoulder is formed between the auxiliary connecting section and the fixed connecting section. The positioning seat is provided with a limiting platform that cooperates with the limiting shoulder.

[0013] Furthermore, the length of the fixed connecting section is L, and 1cm≤L≤3cm. The fixed connecting section and the positioning seat are fixedly connected by an interference fit. The positioning seat is provided with a first auxiliary bolt for pressing against the side wall of the auxiliary connecting section.

[0014] Furthermore, the end of the steel-cutting cutter tube extending outside the bottom mold base is a conical section formed by chamfering.

[0015] The beneficial effects of the adjustable bearing material hot-cutting steel breaking mechanism provided by this utility model are:

[0016] 1. The adjustable positioning component in this utility model facilitates the positioning assistance for cutting material segments of different specifications and lengths. The functional areas have clear division of labor and cooperate with each other, which helps to improve the working efficiency and cutting accuracy of the entire mechanism.

[0017] The design of the positioning rod and the upper die base avoids interference, allowing for the cutting of shorter material segments. This effectively expands the cutting range of the steel cutting mechanism and improves the equipment's versatility and applicability.

[0018] 2. In this utility model, the fixed connecting section of the threaded seat and the positioning seat are fixedly connected by an interference fit. Simultaneously, a first auxiliary bolt is provided to abut against the side wall of the auxiliary connecting section. This double-fixing method ensures the stability of the connection between the threaded seat and the positioning seat, allowing the positioning rod to remain stable during adjustment and use, reducing positioning errors caused by loose connections, and improving the reliability of the mechanism's operation. Furthermore, the shorter fixed connecting section combined with the longer auxiliary connecting section reduces the overall complexity of the threaded seat's installation process.

[0019] 3. The end of the steel cutter barrel extending outside the bottom mold base of this utility model is a conical section. During the hot cutting process, the conical section can better guide the round steel into the cutting position and play an auxiliary cutting role at the moment of cutting, making the cutting process smoother, reducing cutting resistance, improving the steel cutting effect, and also helping to extend the service life of the cutter plate and the cutter barrel.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0031] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0032] An embodiment of an adjustable bearing material hot-cutting steel breaking mechanism provided by this utility model:

[0033] As shown in Figures 1 to 6

[0034] The assembly includes a bottom template 1 and an upper template 2. The bottom template 1 has a bottom mold base 11 for the round steel to pass through in a directional manner. The bottom surface of the upper template 2 has an upper mold base 21, and the upper mold base 21 has a steel-cutting blade 22. The bottom template 1 has a positioning assembly 3 that is spaced apart from the bottom mold base 11. The positioning assembly 3 includes a positioning seat 31 and a positioning rod 32 that is laterally adjustable on the positioning seat 31. The top of the upper template 2 is connected to a stamping mechanism, which drives the steel-cutting blade 22 to move up and down.

[0035] The steel cutting operation is achieved through the bottom template 1 and the upper template 2. The adjustable positioning component 3 facilitates the positioning and auxiliary cutting of material segments of different specifications and lengths. The functional areas have clear division of labor and cooperate with each other, which helps to improve the working efficiency and cutting accuracy of the entire mechanism.

[0036] The upper mold base 21 is provided with clearance grooves 212 that are distributed opposite to the positioning rod 32.

[0037] When cutting shorter material segments, the positioning rod 32 abuts against the end of the heat-treated round steel. The clearance groove 212 can prevent the positioning rod 32 from interfering with the downward movement of the upper die seat 21, thereby enabling the cutting of shorter material segments. This effectively expands the cutting range of the steel cutting mechanism and improves the versatility and applicability of the equipment.

[0038] In this embodiment, the upper mold base 21 is provided with a slot 211 for installing the steel cutting blade 22 on the side close to the lower mold base 11. The lower mold base 11 is provided with a steel cutting blade cylinder 111, and the first end of the steel cutting blade cylinder 111 close to the steel cutting blade 22 extends out of the lower mold base 11.

[0039] The slot 211 provides a precise installation position for the steel cutting blade 22, ensuring that the steel cutting blade 22 is firmly installed on the upper die base 21 and accurately positioned. During the cutting process, the precisely positioned steel cutting blade 22 can better cooperate with the bottom die base 11, ensuring the consistency and accuracy of the cutting position, thereby improving the dimensional accuracy and quality stability of the cut bearing material segment.

[0040] In addition, the design of the slot 211 makes the installation and removal of the steel cutter plate 22 more convenient and quick.

[0041] The upper side of the steel-breaking blade 22 abuts against the upper side wall of the slot 211, and the lower side of the steel-breaking blade 22 abuts against the lower side wall of the slot 211. The depth of the slot 211 is less than the thickness of the steel-breaking blade 22.

[0042] The contact between the steel cutting blade 22 and the side wall of the slot 211 increases the contact area and friction between them, making the connection between the steel cutting blade 22 and the upper die base 21 more robust. When subjected to cutting force, this stable connection method can effectively disperse stress, reduce the deformation and vibration of the steel cutting blade 22, and improve the structural strength and stability of the entire steel cutting mechanism.

[0043] The steel cutting blade 22 is detachably mounted in the slot 211 by bolts. The upper mold base 21 is provided with a through hole 213 for mounting the steel cutting blade 22, and the steel cutting blade 22 is provided with a countersunk hole 221 corresponding to the through hole 213.

[0044] The through hole 213 on the upper mold base 21 and the countersunk hole 221 on the steel cutting blade 22 are correspondingly set, providing an accurate channel for bolt installation. The bolt passes through the through hole 213 and the countersunk hole 221 to fix the steel cutting blade 22 to the upper mold base 21. This installation method can ensure that the connection between the bolt and the steel cutting blade 22 and the upper mold base 21 is firm and reliable, preventing the bolt from loosening during operation.

[0045] In addition, the countersunk hole 221 is designed so that the bolt head can be embedded in the steel cutter plate 22, keeping the surface of the steel cutter plate 22 flat.

[0046] In this embodiment, the positioning seat 31 is provided with a threaded seat 33, and the positioning rod 32 is a lead screw that fits through the threaded seat 33. The lead screw structure facilitates positioning adjustment.

[0047] The threaded seat 33 includes an auxiliary connecting section 331 and a fixed connecting section 332. The diameter of the auxiliary connecting section 331 is smaller than the diameter of the fixed connecting section 332, and a limiting shoulder 333 is formed between the auxiliary connecting section 331 and the fixed connecting section 332. The positioning seat 31 is provided with a limiting platform that cooperates with the limiting shoulder 333.

[0048] The cooperation between the limiting shoulder 333 and the limiting platform plays a role in positioning and limiting, ensuring that the threaded seat 33 is installed in the positioning seat 31 with accurate positioning.

[0049] The fixed connecting section 332 has a length of L1, which is 3cm. The length of the fixed connecting section 332 is less than the length of the auxiliary connecting section 331. The fixed connecting section 332 and the positioning seat 31 are fixedly connected by an interference fit. The positioning seat 31 is provided with a first auxiliary bolt 311 for pressing against the side wall of the auxiliary connecting section 331.

[0050] The fixed connecting section 332 is 3cm long and is fixedly connected to the positioning seat 31 by an interference fit. This length and connection method can provide sufficient connection strength to ensure a tight fit between the threaded seat 33 and the positioning seat 31.

[0051] Tightening the first auxiliary bolt 311 increases the friction between the auxiliary connecting section 331 and the positioning seat 31, thereby improving the installation stability of the threaded seat 33.

[0052] By using a shorter fixed connection section 332 in conjunction with a longer auxiliary connection section 331, the overall installation process of the threaded seat 33 is reduced.

[0053] In this embodiment, the end of the steel cutting blade 111 that extends out of the bottom mold base 11 is a conical section 112 formed by chamfering.

[0054] The conical section 112 is relatively smooth and has no sharp right-angled edges. When the steel cutting blade 22 moves downward, it is close to the side of the conical section 112. During the cutting process, it ensures that the steel cutting blade 22 presses down accurately along the predetermined trajectory, reduces the deformation of the round steel caused by stress change during the cutting process, ensures the flatness and perpendicularity of the cut surface, and improves the cutting quality.

[0055] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0056] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
