Description

Technical Field

[0001] This utility model relates to the field of hammer forging technology, specifically a high-speed hammer forging device with automatic lubrication function. Background Technology

[0002] High-speed hammer forging is an important forming process in metal processing, widely used in aerospace, automotive manufacturing, and mechanical engineering. This process shapes metal materials into desired shapes and properties through high-frequency hammering. However, existing high-speed hammer forging technologies have some significant drawbacks in practical applications:

[0003] During high-speed hammer forging, the friction between the metal and the die or hammer head is high, easily leading to overheating and wear. Traditional lubrication methods typically rely on manual application of lubricating oil, which is not only inefficient but can also result in uneven lubrication, affecting the surface quality and internal structure of the forgings. Existing hammer forging equipment often has a relatively simple lubrication system design, lacking automated control functions. This requires operators to frequently monitor and manually add lubricant, increasing labor costs and operational complexity.

[0004] Uneven or insufficient lubrication often leads to reduced stability during hammer forging, thus affecting the quality of forgings and production efficiency. Excessive wear can also cause equipment failure, increasing maintenance and downtime. Due to insufficient lubrication causing equipment wear, existing hammer forging equipment requires frequent maintenance and component replacement, increasing operating costs and production downtime.

[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a high-speed hammer forging device with automatic lubrication function. Utility Model Content

[0006] The purpose of this invention is to provide a high-speed hammer forging device with automatic lubrication function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A technical solution for a high-speed hammer forging device with automatic lubrication function includes a base for supporting the overall structure, on which a column and a hammer forging seat are fixedly mounted; a rotary motor is fixedly mounted on the column, and a rotating wheel is fixedly connected to the output end of the rotary motor. An eccentric frame is eccentrically hinged to the rotating wheel; an eccentric frame linkage arm is symmetrically hinged to the end of the eccentric frame away from the rotating wheel, and a linkage arm connecting spring is provided between the two sets of eccentric frame linkage arms; a linkage arm tail linkage rod is hinged to the tail end; a hammer forging column is fixedly connected to the end of the linkage arm tail linkage rod away from the eccentric frame linkage arm. A forging head is fixedly installed at the bottom of the column, and a forging column guide sleeve is fitted on the outside. The forging column guide sleeve is fixedly connected to the column through a guide sleeve fixing frame. Lubricating oil boxes are provided on both sides of the forging column guide sleeve. The lubricating oil boxes have oil chambers, and oil-absorbing cotton is provided in the oil chambers. One side of the oil-absorbing cotton abuts against an oil-absorbing cotton push spring, and the other end of the oil-absorbing cotton is in contact with the outer wall of the forging column. A rotary motor drives a rotating wheel to drive an eccentric frame to rotate, and through a linkage component, the forging column moves up and down along the guide sleeve to achieve forging. The lubricating oil boxes automatically provide lubrication to the forging column or forging head through the oil-absorbing cotton.

[0009] As a preferred technical solution, the rotary motor drives the wheel to rotate, and the eccentric frame rotates eccentrically with the wheel. The rotational motion is converted into the linear reciprocating motion of the hammer forging column through the linkage arm of the eccentric frame. The linkage arm is connected to a spring to buffer the impact force during the hammer forging process.

[0010] As a preferred technical solution, the linkage rod at the tail of the linkage arm is hinged to the hammer forging column, and the hinge point between the eccentric frame linkage arm and the linkage rod at the tail of the linkage arm can rotate relative to each other, ensuring smooth power transmission and adapting to the hammer forging action trajectory.

[0011] As a preferred technical solution, the guide sleeve of the hammer forging column is clearance-fitted with the hammer forging column, and the guide sleeve fixing frame is fixedly connected to both the column and the guide sleeve of the hammer forging column, which is used to limit the movement direction of the hammer forging column and prevent deviation.

[0012] As a preferred technical solution, one end of the oil-absorbing cotton push spring abuts against the inner wall of the lubricating oil box, and the other end abuts against the oil-absorbing cotton. Through elastic force, the oil-absorbing cotton is always in close contact with the outer wall of the hammer forging column, and the oil-absorbing cotton absorbs the lubricating oil in the oil cavity to achieve automatic and continuous lubrication.

[0013] As a preferred technical solution, the forging stand is located directly below the forging head and is used to support the workpiece to be forged; the lubricating oil box is detachably connected to the guide sleeve fixing frame, the oil cavity is provided with a filling port for easy replenishment of lubricating oil, and the oil-absorbing cotton is replaceable.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention features a lubricating oil box containing an oil cavity and oil-absorbing cotton. Under the pressure of the oil-absorbing cotton spring, the oil-absorbing cotton remains tightly fitted to the outer wall of the forging column, automatically and continuously providing lubrication to the forging column or forging head. This automatic lubrication method effectively reduces the friction between the metal and the mold or hammer head, preventing overheating and wear. This allows the forging to receive more uniform stress and better lubrication during processing, thereby significantly improving the surface quality and internal structural stability of the forging and ensuring its overall quality.

[0015] This invention utilizes a rotary motor to drive a rotating wheel, which in turn rotates an eccentric frame. Through a linkage mechanism, the forging column reciprocates up and down along a guide sleeve to achieve forging. Simultaneously, a lubrication box automatically provides lubrication to the forging column or forging head. The entire process requires minimal manual intervention, achieving automated lubrication control, significantly reducing labor costs, simplifying operations, and improving production efficiency.

[0016] The automatic lubrication function of this invention ensures uniform and sufficient lubrication during the hammer forging process, making the forging process more stable. A stable forging process reduces fluctuations in forging quality caused by lubrication problems, increases the yield of qualified products, and thus improves overall production efficiency.

[0017] The automatic lubrication function of this invention effectively reduces equipment wear and tear, lowering the incidence of equipment failure. The equipment requires less frequent maintenance and parts replacement, reducing production downtime, lowering operating costs, and improving equipment lifespan and reliability.

[0022] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a high-speed hammer forging device with automatic lubrication function: it includes a base 1 for supporting the overall structure, and a column 2 and a hammer forging seat 31 are installed on the base 1 by means of bolts or other fixing methods to ensure that they are firmly connected and provide stable support for subsequent components.

[0024] The rotary motor 21 is fixedly installed on the column 2 using bolts. The output end of the rotary motor 21 is fixedly connected to the wheel 22, and a key connection or other method can be used to ensure effective power transmission.

[0025] On the rotating wheel 22, an eccentric frame 23 is eccentrically hinged by means of a pin or the like, so that the eccentric frame 23 can perform eccentric movement as the rotating wheel 22 rotates.

[0026] At the end of the eccentric frame 23 furthest from the turntable 22, the eccentric frame linkage arm 24 is symmetrically hinged via a pin. A linkage arm connecting spring 25 is installed between the two sets of eccentric frame linkage arms 24, with both ends of the spring reliably connected to the corresponding eccentric frame linkage arm 24, serving to buffer the impact force during hammer forging. One end of the linkage rod 26 at the tail of the linkage arm is hinged to the tail of the eccentric frame linkage arm 24, and the other end is fixedly connected to the hammer forging column 27, which can be achieved by welding or bolting.

[0027] At the bottom of the forging column 27, the forging head 28 is fixedly installed with bolts. The forging column guide sleeve 29 is fitted onto the outside of the forging column 27, and the forging column guide sleeve 29 is fixedly connected to the column 2 using the guide sleeve fixing bracket 30. The guide sleeve fixing bracket 30 can be bolted to the column 2 and the forging column guide sleeve 29 to limit the movement direction of the forging column 27 and prevent it from deviating during movement.

[0028] Lubricating oil boxes 4 are installed on both sides of the guide sleeve 29 of the forging column. The lubricating oil box 4 and the guide sleeve fixing bracket 30 are detachably connected, such as by snap-fit ​​or bolt connection, to facilitate subsequent maintenance and replacement. An oil cavity 41 is provided inside the lubricating oil box 4, and oil-absorbing cotton 42 is placed in the oil cavity 41. An oil-absorbing cotton push spring 43 is installed on one side of the oil-absorbing cotton 42. One end of the spring abuts against the inner wall of the lubricating oil box 4, and the other end abuts against the oil-absorbing cotton 42, so that the other end of the oil-absorbing cotton 42 is in close contact with the outer wall of the forging column 27.

[0029] When the rotary motor 21 is started, the rotary motor 21 drives the rotating wheel 22 to start rotating. Since the eccentric frame 23 is eccentrically hinged to the rotating wheel 22, the rotation of the rotating wheel 22 will drive the eccentric frame 23 to rotate eccentrically.

[0030] The movement of the eccentric frame 23 is transmitted through the eccentric frame linkage arm 24. The eccentric frame linkage arm 24 converts the rotational motion of the rotary wheel 22 into the linear reciprocating motion of the forging column 27. During this process, the linkage arm connecting spring 25 buffers the impact force generated during forging, protecting all linkage components.

[0031] The linkage rod 26 at the tail of the linkage arm moves with the eccentric frame linkage arm 24, driving the forging column 27 to reciprocate up and down along the forging column guide sleeve 29. The forging head 28 at the bottom of the forging column 27 moves up and down accordingly, performing forging operation on the workpiece placed on the forging seat 31.

[0032] Lubricating oil is pre-injected into the oil cavity 41, and the oil-absorbing cotton 42 absorbs the lubricating oil in the oil cavity 41. The oil-absorbing cotton pushes the spring 43, and through the elastic force, keeps the oil-absorbing cotton 42 tightly pressed against the outer wall of the forging column 27. When the forging column 27 moves up and down, the oil-absorbing cotton 42 automatically applies the absorbed lubricating oil to the outer wall of the forging column 27, thereby providing continuous lubrication for the forging column 27 or the forging head 28.

[0033] Place the workpiece to be forged on the hammer forging stand 31, ensuring that the workpiece is placed stably.

[0034] When the power switch of the rotary motor 21 is turned on, the rotary motor 21 starts working, driving the rotating wheel 22 to rotate, which in turn drives the eccentric frame 23, the eccentric frame linkage arm 24 and other linkage components to move, causing the forging hammer column 27 to move up and down along the forging hammer column guide sleeve 29, and the forging hammer head 28 to begin the forging operation on the workpiece. At the same time, the oil-absorbing cotton 42 in the lubrication box 4 automatically provides lubrication for the forging hammer column 27 or the forging hammer head 28.

[0035] During the hammer forging process, operators need to closely observe the operation of the equipment, including the working status of the rotary motor 21, the movement of each linkage component, and the hammer forging effect of the forging head 28 on the forging workpiece. At the same time, they should observe the lubrication status of the lubricating oil to ensure good lubrication.

[0036] The working principle and usage process of this utility model: After assembling each component of this solution in sequence, work according to the above implementation methods according to actual needs to complete all working steps.
