Description

Technical Field

[0001] The utility model belongs to the technical field of steel forgings, and specifically relates to a high-strength cylinder-type forging. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal blanks. By applying pressure to the metal blanks to cause plastic deformation, their mechanical properties can be changed. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the blanks during processing. A high-strength cylindrical forging is a cylindrical part with high strength and durability manufactured by a metal forging process. This type of forging is usually used in applications that withstand high pressure, high temperature or other harsh working conditions, such as automobile engine cylinders, aircraft engine cylinders, oil rig pipe strings, etc. In the production process, high-strength cylindrical forgings usually adopt a hot forging process, that is, the metal blank is heated to a plastic state at high temperature, and then pressure is used to make it flow in the mold and form the desired cylindrical shape. This forging process can provide higher mechanical properties and better blank shape control, so that the forging has excellent strength and toughness.

[0003] The patent application with the publication number CN216972686U discloses a low-alloy high-strength structural steel forging, including a base, a protective component fixedly connected inside the base, a pressure-resistant component fixedly connected outside the base, the protective component including a toughness layer fixedly connected inside the base, an anti-adhesive layer fixedly connected inside the toughness layer, an anti-oxidation layer fixedly connected inside the anti-adhesive layer, an anti-rust layer fixedly connected inside the anti-oxidation layer, and an impact-resistant layer fixedly connected outside the base, an insulating layer fixedly connected outside the impact-resistant layer, a waterproof layer fixedly connected outside the insulating layer, and a corrosion-resistant layer fixedly connected outside the waterproof layer. The low-alloy high-strength structural steel forging achieves the purpose of protecting the steel forging through the protective component, and at the same time, by utilizing the coordination between the internal materials, the rust and corrosion resistance of the steel forging is improved, and the practicality of the steel forging is improved.

[0004] Although the low-alloy high-strength structural steel forgings in the above-mentioned application achieves the purpose of protecting the steel forgings through the protective components, the steel forgings are only treated with rust resistance and corrosion resistance. The forging structure in the above-mentioned patent is unreasonable, resulting in poor overall strength performance, which affects the use effect of the forgings and reduces the service life of the forgings. After forging is completed, the above-mentioned forgings cannot be grasped well, thereby reducing the safety and practicality of the forgings during use.

[0005] In summary, the utility model provides a high-strength cylinder forging to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a high-strength cylindrical forging, which has the advantage that the device can provide sealing protection for the forging body through an arc-shaped sealing ring sleeved on the circumferential side of the forging body, and the sealing ring can increase the friction force so that the first clamping plate, the second clamping plate and the forging body fit tightly, thereby improving the safety of the forging when in use, and the provision of the first limiting hole and the second limiting hole can quickly position the forging body, thereby facilitating the grasping of the device and effectively improving the practicability of the device, and at the same time can utilize the elastic deformation of the spring so that the first clamping plate and the second clamping plate can rotate and cooperate under the action of the rotating rod, the device structure is simple and the stability of the device is improved.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A high-strength cylindrical forging comprises: a forging body, a first clamping plate slidingly engaged with an outer side of the forging body, one end of the first clamping plate rotatably engaged with a rotating rod, and two ends of the rotating rod rotatably engaged with a second clamping plate, the first clamping plate and the second clamping plate are respectively fixed with a first positioning block and a second positioning block at one end of the rotating rod relative to the first clamping plate and the second clamping plate, and the first positioning block and the second positioning block are arranged opposite to each other, the first positioning block and the second positioning block are respectively provided with a first bevel groove and a second bevel groove on the opposite sides of the upper ends, the first positioning block and the second positioning block are respectively provided with a first limiting hole and a second limiting hole in the middle, and the first positioning block and the second positioning block are respectively provided with a notch at the bottom, and a spring is fixedly connected between the two ends of the notch.

The setting of the reinforcement layer further strengthens the strength of the forging body and improves the load-bearing capacity of the device. The anti-rust layer is a rust conversion layer, which can convert the rust inside the forging body into a black organic iron compound, thereby generating a composite film composed of chemical bonds and physical bonds on the surface of the steel, so that the steel body is separated from the outside and is no longer corroded.

The wear-resistant layer is utilized to increase the wear resistance of the forging body, thereby increasing the service life of the forgings.

[0019] By adopting the above technical solution, the arc-shaped sealing ring is matched with the forging body, and the arc-shaped sealing ring is used to reduce the damage to the forging body when it is clamped. The arc-shaped sealing ring can also increase the friction force and improve the safety of the device when clamping.

[0020] The utility model is further configured as follows: the steel base layer, the impact-resistant cold-worked steel layer and the reinforcement layer are forged integral structures.

[0021] By adopting the above technical scheme, the steel base layer, the impact-resistant cold-worked steel layer and the reinforced layer are used as a forged integrated structure, which effectively improves the strength and density of the forging body, and the forged integrated structure has fewer production processes, thereby improving the practicability of the device.

[0022] In summary, the beneficial technical effects of the utility model are:

[0023] 1. The device can provide sealing protection for the forging body by means of an arc-shaped sealing ring sleeved on the circumferential side of the forging body.

The setting of the first limiting hole and the second limiting hole can quickly position the forging body, thereby facilitating the grasping of the device and effectively improving the practicality of the device. At the same time, the elastic deformation of the spring can be utilized so that the first clamping plate and the second clamping plate can rotate and cooperate under the action of the rotating rod. The device structure is simple and the stability of the device is improved.

[0024] 2. The arc-shaped fins are used to increase the heat dissipation area of ​​the forging body, thereby improving the heat dissipation effect.
