Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a wear-resistant hydraulic oil cylinder blank forging. Background Art

[0002] Hydraulic cylinder generally refers to a hydraulic cylinder. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. Existing hydraulic cylinders are generally cylindrical in structure. During the subsequent fine processing of hydraulic cylinder blank forgings, processing equipment often clamps and fixes the hydraulic cylinder blank forgings in a line contact manner, which makes the stability of the hydraulic cylinder blank forgings in the subsequent processing process not high. Moreover, the outside of the hydraulic cylinder is generally not well protected. In some usage scenarios, it will come into contact with other objects and cause wear. Therefore, there is an urgent need for a wear-resistant hydraulic cylinder blank forging. Utility Model Content

[0003] The purpose of the utility model is to provide a wear-resistant hydraulic cylinder forging with a reasonable design to solve the above problems in view of the defects and shortcomings of the existing technology.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: it comprises a cylindrical cylinder body and a flange ring, wherein the flange ring is fixedly arranged above the outer ring wall of the cylindrical cylinder body:

[0005] It also contains:

[0006] Reinforcement ribs, which are multiple and fixedly arranged at the lower part of the flange ring with equal radius distribution, and are fixedly connected to the outer ring wall of the cylindrical cylinder body;

[0007] There are several anti-wear ribs, which are distributed with equal radius and fixedly arranged on the outer ring wall of the cylindrical cylinder body, and the anti-wear ribs are fixedly arranged on the lower part of the reinforcing rib plate.

[0008] Furthermore, an extended ring edge is integrally formed on the upper portion of the cylindrical cylinder body, and the extended ring edge is located above the flange ring.

[0009] Furthermore, a mounting groove is provided on the inner ring wall of the extended ring edge.

[0010] Furthermore, four measuring lines are distributed on the upper part of the extended ring edge at equal rounded corners.

[0011] Furthermore, the corners of the reinforcing ribs and the anti-wear ribs are provided with arc corners.

[0012] Compared with the prior art, the beneficial effect of the present invention is that the wear-resistant hydraulic cylinder blank forging described in the present invention can not only provide wear-resistant protection for the outer side of the cylinder body, but also provide more and more stable surface contact points during the subsequent processing and fixing process, thereby improving the stability of the blank forging in subsequent processing.

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0020] like Figures 1-4As shown, this specific embodiment adopts the following technical solution: it includes a cylindrical cylinder body 1 and a flange ring 2, the flange ring 2 is fixedly arranged above the outer ring wall of the cylindrical cylinder body 1, and an extended ring edge 5 is integrally formed on the upper part of the cylindrical cylinder body 1, and the extended ring edge 5 is located above the flange ring 2. After the hydraulic cylinder is sealed, the height difference formed by the extended ring edge 5 and the flange ring 2 can effectively improve the sealing performance of the connection between the sealing components such as the sealing cover of the hydraulic cylinder and the flange ring 2, and prevent foreign dust and other impurities from entering directly from the connection gap between the sealing component and the flange ring 2. Entering into the cylindrical cylinder body 1, a mounting groove 6 is provided on the inner ring wall of the extended ring edge 5. A wear-resistant bushing can be installed in the cylindrical cylinder body 1, and the mounting and fixing parts of the wear-resistant bushing are assembled into the mounting groove 6. During the operation of the hydraulic cylinder, the piston can be prevented from directly contacting the inner wall of the cylindrical cylinder body 1 and causing wear of the inner wall of the cylindrical cylinder body 1. Four measuring lines 7 are distributed on the upper corners of the extended ring edge 5. In the subsequent processing of the blank forging, the measuring lines 7 are measured to facilitate the measurement and confirmation of the inner diameter and center position of the mounting groove 6:

[0021] It also contains:

[0022] The reinforcing ribs 3 are several in number and are fixedly arranged at the lower part of the flange ring 2 with equal radius distribution. The reinforcing ribs 3 are fixedly connected to the outer ring wall of the cylindrical cylinder body 1;

[0023] Anti-wear ribs 4, there are several anti-wear ribs 4, which are fixedly arranged on the outer ring wall of the cylindrical cylinder body 1 with equal fillet distribution, and the anti-wear ribs 4 are fixedly arranged at the lower part of the reinforcing rib plate 3. The corners of the reinforcing rib plate 3 and the anti-wear ribs 4 are provided with arc angles 8. The setting of the arc angles 8 can avoid the reinforcing rib plate 3 and the anti-wear ribs 4 from forming a right angle in the forging die, thereby reducing the difficulty of demolding the blank forging after forging;

[0024] When using the present invention, the reinforcing rib plate 3 can improve the structural strength between the flange ring 2 and the cylindrical cylinder body 1, and in combination with the anti-wear ribs 4, the overall structure of the blank forging can be strengthened. Moreover, in the subsequent processing of the blank forging, the processing equipment can not only directly clamp and fix the cylindrical cylinder body 1, but also apply a fixed fulcrum to the reinforcing rib plate 3 or the anti-wear rib 4, thereby realizing surface contact between the processing equipment and the reinforcing rib plate 3 or the anti-wear rib 4, and improving the stability of the blank forging during subsequent processing. The anti-wear rib 4 can also provide protection for the outside of the cylindrical cylinder body 1, reducing the phenomenon of wear caused by direct contact between objects and the outside of the cylindrical cylinder body 1.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The cooperation between the reinforcing ribs 3 and the anti-wear ribs 4 not only provides wear-resistant protection for the outer side of the cylindrical cylinder body 1, but also provides more and more stable surface contact points during the subsequent processing and fixing process, thereby improving the stability of the blank forging during subsequent processing;

[0027] After the hydraulic cylinder is sealed, the height difference formed by the extended ring edge 5 and the flange ring 2 can effectively improve the sealing performance of the connection between the sealing components such as the sealing cover of the hydraulic cylinder and the flange ring 2, and prevent external dust and other impurities from directly entering the cylindrical cylinder body 1 through the connection gap between the sealing component and the flange ring 2.

[0028] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
