Description

Technical Field

[0001] The utility model relates to the technical field of the main body of a hydraulic press, in particular to a main body structure of a sunken hydraulic cylinder of a multi-directional die forging hydraulic press. Background Art

[0002] In recent years, with the rapid development of the automotive, aerospace, agricultural, surgical instrument and hand tool industries, multi-directional die forging hydraulic presses have gradually been widely used in the forging industry due to their advantages such as enabling the forming of forgings with complex structural shapes, significantly improving material utilization rate, reducing machining man-hours and costs, and enhancing their mechanical properties.

[0003] At present, the main body structure of multi-directional die forging hydraulic presses used in the forging industry generally includes a frame part, a slider part and a hydraulic cylinder part. Since the structural shape of the die, the size and stroke of the hydraulic cylinder and the operating space need to be considered, sufficient position space needs to be reserved in the inner compartment when designing the frame, resulting in an overly large main body structure of the multi-directional die forging hydraulic press, which not only increases costs and occupies too much floor space, but also is not conducive to the stability of the main body structure.

[0004] For the main body structure of the new multi-directional die forging hydraulic press with sunken hydraulic cylinders, the cylinder bodies of the left and right hydraulic cylinders are sunk into the main body frame by a certain part, reducing the size of the inner compartment of the frame, thereby reducing the size of the entire main body structure in the length direction, reducing costs, and increasing the stability of the main body structure by reducing the aspect ratio. Such a main body structure occupies a small floor space, has a high utilization rate, and can better meet the market demand. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing main body structure of hydraulic cylinders, the utility model provides a main body structure of a sunken hydraulic cylinder of a multi-directional die forging hydraulic press, which has the advantages of being able to reduce the size of the entire main body structure by reducing the size of the inner compartment of the frame, not only reducing costs but also increasing the stability of the main body structure, and solves technical problems such as the stability of the main body structure of the multi-directional die forging hydraulic press.

[0006] The utility model provides the following technical solution: A main body structure of a sunken hydraulic cylinder of a multi-directional die forging hydraulic press, comprising a frame and a hydraulic cylinder, further comprising:

[0007] A backing plate, arranged inside the frame, the backing plate is composed of an upper backing plate and a lower backing plate, stiffening plates Ⅰ and Ⅱ are fixedly welded on the outer side of the lower backing plate, and stiffening plate Ⅲ is fixedly welded on the inner side of the lower backing plate.

[0008] Preferably, the contact surfaces between the lower backing plate and the frame, stiffening plate Ⅰ, stiffening plate Ⅱ and stiffening plate Ⅲ are fixedly welded by U-shaped welds.

[0009] Preferably, a mounting plate is fixedly connected to the end of the hydraulic cylinder. A slide rail is arranged on the lower side of the mounting plate. A workbench is fixedly installed on the machine body below the slide rail, and the slide rail is fixedly installed on the workbench.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. By designing the lower backing plate, rib plate I, rib plate II, and rib plate III, etc., and calculating the sizes of the hydraulic cylinders on both sides, the inner backing plate of the machine body column is divided into two parts: the upper backing plate and the lower backing plate. The lower backing plate moves inward by a distance H. According to the size of the hydraulic cylinder, rib plate I and rib plate II are added outside the lower backing plate, and rib plate III is added inside the lower backing plate to increase the strength of the overall structure. A U-shaped weld is processed on the side of the backing plate and rib plate III to increase the welding contact area and ensure firm welding. With such a structure, the hydraulic cylinders on both sides can be sunk into the main body structure at the same time. In this way, the length dimension of the multi-directional forging main body structure can be reduced by twice H. By changing the main body structure of the machine body and sinking the hydraulic cylinders on both sides into the machine body, the size of the inner span of the machine body is reduced, the cost is reduced, the stability of the structure is increased, the economic benefit is improved, the market application range is expanded, and the needs of customers can be better met.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Please refer to Figures 1-4 , a main structure of a submerged hydraulic cylinder of a multi-directional die forging hydraulic press, including a machine body 1 and a hydraulic cylinder 2. The hydraulic cylinder 2 is submerged inside the machine body 1. A backing plate is arranged inside the machine body 1. The backing plate is divided into an upper backing plate and a lower backing plate 3. Reinforcing plate I 4 and reinforcing plate II 5 are fixedly welded to the outside of the lower backing plate 3. Reinforcing plate III 6 is fixedly welded to the inside of the lower backing plate 3. An installation plate 7 is fixedly connected to the end of the hydraulic cylinder 2. A slide rail 8 is arranged on the lower side of the installation plate 7. A workbench 9 is fixedly installed on the machine body 1 below the slide rail 8. The slide rail 8 is fixedly installed on the workbench 9.

[0019] Please refer to Figures 1-4 , the contact surfaces between the lower backing plate 3 and the machine body 1, the reinforcing plate I 4, the reinforcing plate II 5 and the reinforcing plate III 6 are fixedly welded by U-shaped welds, which can increase the welding area and ensure firm welding between the lower backing plate 3 and the machine body 1, the reinforcing plate I 4, the reinforcing plate II 5 and the reinforcing plate III 6, and improve the stability.

[0020] Working principle: By calculating the size of the hydraulic cylinder 2, the backing plate inside the machine body 1 is divided into upper and lower parts: the upper backing plate and the lower backing plate 3. The lower backing plate 3 moves inward by a distance H. On the outside of the lower backing plate 3, the reinforcing plate I 4 and the reinforcing plate II 5 are designed according to the structural dimensions of the hydraulic cylinder 2. On the inside of the lower backing plate 3, the reinforcing plate III 6 is added. Through the reinforcing plate I 4, the reinforcing plate II 5 and the reinforcing plate III 6, the strength and stability of the overall structure of the machine body 1 are increased. U-shaped welds are processed on the contact surfaces between the backing plate and the machine body 1, the reinforcing plate I 4, the reinforcing plate II 5 and the reinforcing plate III 6 to increase the welding contact area and ensure firm welding between the parts. The hydraulic cylinders 2 on both sides simultaneously adopt the structure of being submerged inside the machine body 1, and the hydraulic cylinders 2 on both sides can be simultaneously submerged inside the machine body 1 by a dimension H. The inner dimension of the machine body is reduced by twice H, and the dimension of the main structure in the length direction is twice H, which increases the compactness and stability of the structure. The letter H proposed in the present utility model represents the distance that the lower backing plate 3 moves inward.
