Description

Technical Field

[0001] The invention relates to the field of forging machines, in particular to an automobile control arm forging machine for dustproof lubrication of a guide rod. Background Art

However, as dust continues to accumulate on the guide rod, even after preliminary cleaning with a sponge pad, some fine particles may remain and mix with the lubricating oil to form sludge, increasing the friction resistance of the guide rod during movement, thereby affecting the smooth operation of the forging process. Therefore, there is a need for an automotive control arm forging machine that integrates efficient dust prevention, automatic cleaning, and intelligent lubrication management to reduce dust contamination of the guide rod and prevent the formation of sludge on the guide rod. Summary of the invention

At the same time, the rotating blades continuously stir the lubricating oil to ensure that it is evenly distributed and effectively covers the surface of the guide rod, thereby reducing movement resistance.

[0006] In order to solve the problems of the prior art, the present invention provides an automobile control arm forging machine for dustproof lubrication of guide rods, comprising a machine body, the machine body is provided with a bottom plate for placing the control arm and a forging plate for applying pressure to the control arm, the forging plate is symmetrically provided with a pair of guide rods extending vertically upward, the machine body is provided with a guide sleeve sleeved on each of the guide rods, each of the guide sleeves is provided with a dustproof lubrication component for preventing sludge from accumulating on the guide rod, the dustproof lubrication component comprises an upper bellows and a lower bellows, the upper bellows is connected between the upper end of the guide rod and the guide sleeve, the lower bellows is connected between the lower end of the guide rod and the guide sleeve, a sealed space for enclosing the guide rod is formed between the upper bellows, the lower bellows and the guide sleeve, a lubrication space for injecting lubricating oil is formed between the guide sleeve and the guide rod, an oil filling port connected to the lubrication space is provided on the guide sleeve, and a plurality of balls for rolling contact with the guide rod are evenly distributed on the guide sleeve along its circumferential direction.

[0007] Preferably, the dustproof lubrication assembly also includes a rotating blade arranged in the lubrication space, and the rotating blade can rotate around the guide rod in the lubrication space. When the rotating blade is in a working state, the lubricating oil in the lubrication space is in a continuously stirred state, and the lubricating oil is evenly applied to the surface of the guide rod.

[0008] Preferably, the lower end of the guide sleeve is provided with an inverted cone base coaxial therewith, and the inverted cone base is provided with a sealing rubber ring sleeved on the guide rod to prevent the lubricating oil from flowing downward and accumulating on the forging plate.

[0010] Preferably, a coaxial rotating sleeve is provided in the guide sleeve, the rotating sleeve has an embedding hole for each ball to be embedded therein, and the lower end of the rotating sleeve has a slot engaged with the rotating blade. When the rotating blade rotates, the rotating sleeve drives all the balls to rotate synchronously.

[0011] Preferably, gaps are left between the rotating ring sleeve and the guide sleeve and the guide rod to allow lubricating oil to flow downward.

[0012] Preferably, an oil drain port for draining excess lubricating oil is provided on the inverted cone base.

[0013] Preferably, a plurality of the rotating blades are evenly distributed in the lubrication space along the circumferential direction of the guide rod, and a bearing connecting all the rotating blades is provided on the guide sleeve.

[0014] Preferably, the guide sleeve is evenly provided with a plurality of air inlets along its circumferential direction, each rotating blade is provided with a pressure plate capable of withstanding wind impact, and the guide sleeve is also provided with an air outlet for pressure relief.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention prevents external dust and impurities from entering the working area by sealing the guide rod with the upper bellows and the lower bellows during the lifting and lowering of the forging plate, ensures that the lubricating oil can be well maintained in the lubrication space and evenly distributed on the surface of the guide rod, and avoids the lubricating oil from contacting with dust to form sludge.

[0016] As the guide rod follows the movement of the forging plate, multiple balls arranged in the circumferential direction of the guide sleeve roll in contact with the guide rod, reducing friction, enhancing the smooth operation of the guide rod, and reducing wear. This not only ensures the smooth progress of the forging process, but also effectively avoids the jamming or wear of the guide rod caused by impurities, thereby improving the efficiency of the forging process.

[0017] 2. The present invention causes the lubricating oil to be continuously stirred by rotating the rotating blades around the guide rod in the lubrication space, thereby ensuring uniform distribution of the oil and preventing sedimentation or stratification, more effectively covering and evenly coating the entire surface of the guide rod to form a protective film, further reducing the friction coefficient of contact with the ball and reducing the risk of obstruction to the up and down movement of the guide rod.

[0018] In addition, the sealing rubber ring effectively blocks the lubricating oil from flowing downward to accumulate on the forging plate, avoiding the lifting interference caused by the accumulation and solidification of the lubricating oil, and ensuring that the surface of the guide rod is continuously fully lubricated.

[0019] 3. The present invention injects lubricating oil into the ring groove through the oil filling port, ensuring that the lubricating oil can evenly cover the surface of the ball, and brings the lubricating oil to the contact surface between the ball and the guide rod as the rotating ring sleeve rotates synchronously, reducing friction and preventing wear. The oil discharge port effectively discharges excess lubricating oil to prevent it from accumulating and solidifying and affecting the movement of the guide rod.

[0020] Secondly, the hot air flow is introduced into the guide sleeve through the air inlet, which reduces the viscosity of the lubricating oil and enhances its fluidity. At the same time, the rotating blades rotate driven by the hot air flow, further promoting the uniform application and flow of the lubricating oil, avoiding the local accumulation or lack of lubricating oil, and improving the smoothness of the guide rod following the forging plate.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] See also Figure 1-Figure 5 As shown, a forging machine for automobile control arms for dustproof lubrication of guide rods comprises a machine body 1, on which a bottom plate 3 for placing a control arm 2 and a forging plate 4 for applying pressure to the control arm 2 are provided, on which a pair of guide rods 41 extending vertically upward are symmetrically provided, on which a guide sleeve 42 is provided on the machine body 1, on which each of the guide rods 41 is sleeved, and on which each of the guide sleeves 42 is provided a dustproof lubrication component 5 for preventing sludge from accumulating on the guide rods 41, a lubrication space 421 for injecting lubricating oil is formed between the guide sleeves 42 and the guide rods 41, an oil filling port 422 communicating with the lubrication space 421 is provided on the guide sleeves 42, and a plurality of balls 423 for rolling contact with the guide rods 41 are evenly distributed along the circumferential direction of the guide sleeves 42.

[0037] The machine body 1 is provided with a hydraulic cylinder 11 for driving the forging plate 4 to move up and down.

[0038] During the operation of the forging machine for the automobile control arm 2, the control arm 2 to be processed is first placed on the base plate 3 to prepare for the forging operation. When the forging process starts, the hydraulic cylinder 11 starts to work, driving the forging plate 4 and the guide rod 41 connected thereto to move downward along the guide sleeve 42. In this process, since the lubricating space 421 formed between the guide sleeve 42 and the guide rod 41 is pre-injected with lubricating oil, and the lubricating oil is regularly replenished through the oil filling port 422 on the guide sleeve 42, the guide rod 41 can be fully lubricated during each lifting process. At the same time, the multiple balls 423 distributed in the circumferential direction of the guide sleeve 42 are in rolling contact with the guide rod 41, which not only reduces the friction, but also further enhances the smooth operation of the guide rod 41 and reduces the possibility of wear.

[0039] As the forging plate 4 gradually approaches the control arm 2, the pressure applied by it gradually increases until it reaches a predetermined pressure value, completing the forging operation of the control arm 2. During the forging process, dust-proof lubrication measures are used to effectively prevent the guide rod 41 from being stuck or worn due to impurities such as dust and debris. In addition, the presence of the lubrication space 421 and the use of the ball 423 greatly reduce the friction resistance between the guide rod 41 and the guide sleeve 42, ensuring the smooth progress of the forging process.

[0040] After forging is completed, the hydraulic cylinder 11 drives the forging plate 4 and the guide rod 41 to retreat to the initial position. At this time, since the dustproof lubrication component 5 provided in the guide sleeve 42 continues to play a role, the surface of the guide rod 41 can be kept clean and smooth even after long-term use. This not only improves work efficiency, but also reduces maintenance costs and failure rates.

[0041] See also Figure 1-Figure 5 As shown, the dustproof lubrication assembly 5 includes an upper bellows 51 and a lower bellows 52, wherein the upper bellows 51 is connected between the upper end of the guide rod 41 and the guide sleeve 42, and the lower bellows 52 is connected between the lower end of the guide rod 41 and the guide sleeve 42, and a sealed space is formed between the upper bellows 51, the lower bellows 52 and the guide sleeve 42 to enclose the guide rod 41.

[0042] When the guide rod 41 is installed in the guide sleeve 42, the upper bellows 51 and the lower bellows 52 in the dustproof lubrication assembly 5 have a dustproof effect on the guide rod 41, and a completely sealed space is formed between the upper bellows 51, the lower bellows 52 and the guide sleeve 42, which tightly surrounds the guide rod 41. Not only can it effectively prevent external dust, impurities and other pollutants from entering the working area of ​​the guide rod 41, but it also ensures that the lubricating oil can be well maintained and distributed on the surface of the guide rod 41 in the sealed space.

[0043] When the hydraulic cylinder 11 drives the forging plate 4 and the guide rod 41 to move up and down, the bellows expands and contracts, but always maintains sealing to prevent any external factors that may affect the smooth operation of the guide rod 41 from invading. In this process, the lubricating oil in the sealed space can continuously provide necessary lubrication for the guide rod 41, reduce friction, and avoid wear problems caused by dust or debris, ensuring the smooth progress of the entire forging process.

[0044] See also Figure 1 and Figure 5-Figure 11 As shown, the dustproof lubrication assembly 5 also includes a rotating blade 53 arranged in the lubrication space 421, and the rotating blade 53 can rotate around the guide rod 41 in the lubrication space 421. When the rotating blade 53 is in the working state, the lubricating oil in the lubrication space 421 is in a continuously stirred state, and the lubricating oil is evenly applied to the surface of the guide rod 41.

[0045] When the hydraulic cylinder 11 drives the forging plate 4 and the connected guide rod 41 to move up and down, the rotating blade 53 in the dustproof lubrication assembly 5 rotates around the guide rod 41 in the lubrication space 421. The rotating action makes the lubricating oil in the lubrication space 421 always in a state of continuous stirring, ensuring that the lubricating oil will not settle or stratify, thereby maintaining the uniformity of the oil quality. Through continuous stirring, the lubricating oil can more effectively cover the surface of the guide rod 41, At the same time, driven by the rotating blades 53, the lubricant is evenly applied to the entire surface of the guide rod 41 to form a protective film. This not only greatly reduces the friction coefficient between the guide rod 41 and the guide sleeve 42, but also prevents the risk of the guide rod 41 being blocked when moving up and down, and ensures that the guide rod 41 can obtain the best lubrication effect during each lifting process, further enhancing the stability and efficiency of the forging process.

[0046] See also Figure 5-Figure 7 As shown, the lower end of the guide sleeve 42 is provided with an inverted conical base 43 coaxial therewith, and the inverted conical base 43 is provided with a sealing rubber ring 431 sleeved on the guide rod 41 to prevent the lubricating oil from flowing downward and accumulating on the forging plate 4.

[0047] When the guide rod 41 moves along the guide sleeve 42 as the forging plate 4 moves up and down, the lubricating oil is injected into the lubricating space 421 and coated on the surface of the guide rod 41, so that the contact between the guide rod 41 and the ball 423 is smoother. As the lubricating oil flows downward on the guide rod 41 due to gravity, the sealing rubber ring 431 effectively blocks the downward flow of the lubricating oil and prevents it from accumulating on the forging plate 4.

[0048] At the same time, the conical surface of the inner wall of the inverted conical base 43 is utilized so that the lubricating oil can be evenly distributed around the guide rod 41 in the lubricating space 421. Unnecessary loss and waste are avoided, and at the same time, sufficient lubrication is ensured to be continuously obtained on the surface of the guide rod 41. The accumulation and solidification of the lubricating oil in the area between the forging plate 4 and the guide sleeve 42 is avoided, which causes interference in the lifting and lowering of the guide rod 41.

[0049] See also Figure 6 , Figure 7 and Fig.12 As shown, the inner wall of the guide sleeve 42 has an annular groove 4231 along its circumferential direction in which the balls 423 can rotate. The guide sleeve 42 is provided with an oil filling port 422 connected to the annular groove 4231, and all the balls 423 can move along the path of the annular groove 4231 and pass through the oil filling port 422.

[0050] When the guide rod 41 moves along the guide sleeve 42 as the forging plate 4 moves up and down, the lubricating oil is injected into the lubricating space 421 through the oil injection port 422 on the guide sleeve 42 that is connected to the annular groove 4231. The oil injection port 422 not only provides the necessary lubricating oil supply for the lubricating space 421, but also ensures that all the balls 423 can move through the oil injection port 422 along the path of the annular groove 4231 due to the position of the oil injection port 422.

[0051] Whenever the balls 423 move to the oil injection port 422, all the balls 423 will contact the freshly injected lubricating oil, so that the contact between the balls 423 and the surface of the guide rod 41 remains smooth. This ensures that the lubricating oil can be continuously and evenly distributed between the balls 423 and the guide rod 41, effectively reducing friction and preventing wear, ensuring the smooth operation of the guide rod 41 and extending its service life.

[0052] See also Figure 6-Figure 12 As shown, the guide sleeve 42 is provided with a coaxial rotating ring sleeve 54, the rotating ring sleeve 54 has an embedding hole for each ball 423 to embed therein, and the lower end of the rotating ring sleeve 54 has a slot 5421 that is engaged with the rotating blade 53. When the rotating blade 53 rotates, the rotating ring sleeve 54 drives all the balls 423 to be in a synchronous rotation state.

[0053] The rotating ring sleeve 54 is composed of an upper ring body 541 and a lower ring body 542 , and the clamping groove 5421 is provided on the lower ring body 542 .

[0054] When the rotating ring 54 is driven to rotate by the rotating blades 53, all the balls 423 embedded therein also enter a synchronous rotation state. The rotating action of the rotating ring 54 helps to evenly bring the fresh lubricating oil injected through the oil injection port 422 to the surface of the balls 423, ensuring the continuity of the lubrication effect between the balls 423 and the guide rods 41.

[0055] While reducing the friction between the guide rod 41 and the ball 423 , it also promotes the uniform distribution of the lubricating oil in the entire lubricating space 421 .

[0056] See also Figure 6 and Figure 7 As shown, there is a gap between the rotating ring sleeve 54 and the guide sleeve 42 and the guide rod 41 for the lubricating oil to flow downward.

[0057] As the lubricating oil is injected into the lubricating space 421 through the oil injection port 422, it not only covers the surface of the ball 423 to provide necessary lubrication, but also slowly flows downward along the gap between the rotating ring sleeve 54 and the guide sleeve 42 and the guide rod 41. The lubricating oil continuously flows into the lubricating space 421, ensuring the comprehensiveness and continuity of the lubricating effect.

[0058] During the rotation of the rotating ring 54, the lubricating oil is continuously brought to the contact surface between the ball 423 and the guide rod 41, and flows down evenly along the gap, thereby avoiding the accumulation or lack of lubricating oil in a single location. This not only ensures low-friction movement between the ball 423 and the guide rod 41, but also promotes the balanced distribution of lubricating oil in the entire lubrication space 421. This helps prevent the accumulation of lubricating oil in one place and avoids the performance degradation caused by the accumulation of sludge lubricating oil.

[0059] See also Figure 6 and Figure 7 As shown, an oil drain port 432 is provided on the inverted conical base 43 for draining excess lubricating oil.

[0060] During the operation of the forging machine for the automobile control arm 2, as the lubricating oil is injected through the oil filling port 422 and flows downward along the gap between the rotating ring sleeve 54 and the guide sleeve 42 and the guide rod 41, excess lubricating oil will inevitably be generated in the lubricating space 421. If the excess lubricating oil is not handled, it may accumulate, and for a long time, it will solidify and affect the up and down movement of the guide rod 41. When the lubricating oil is fully effective in the lubricating space 421, the excess lubricating oil will naturally flow to the bottom due to gravity, and be pumped out through the oil discharge port 432 connected to the pump body.

[0061] The oil drain port 432 not only discharges excess lubricating oil, but also helps maintain the cleanliness of the lubricating space 421 and prevents unnecessary accumulation of lubricating oil inside, thereby ensuring the optimization of the lubricating effect and avoiding the waste of lubricating oil and possible operational interference caused by the accumulation of lubricating oil.

[0062] See also Figure 6-Figure 11 and Fig.13 As shown, a plurality of rotating blades 53 are evenly distributed in the lubrication space 421 along the circumferential direction of the guide rod 41 , and a bearing 531 connecting all the rotating blades 53 is provided on the guide sleeve 42 .

[0063] The rotating motion of the rotating blade 53 helps to continuously renew the lubricating oil film on the surface of the guide rod 41. As the hydraulic cylinder 11 drives the forging plate 4 and the guide rod 41 to move up and down, the rotating blade 53 rotates continuously, so that the lubricating oil can cover the entire surface of the guide rod 41 and form a continuous and uniform protective film, making the contact between the guide rod 41 and the ball 423 smoother.

[0064] In addition, the rotating blades 53 also help to avoid the problem of local accumulation of lubricating oil in the lubricating space 421. By constantly stirring the lubricating oil, the rotating blades 53 can prevent the lubricating oil from excessively accumulating or stratifying in certain areas, thereby ensuring the quality and efficiency of the lubricating oil.

[0065] See also Figure 6 , Figure 7 and Fig.13 As shown, the guide sleeve 42 is evenly provided with a plurality of air inlets 424 along its circumferential direction, each rotating blade 53 is provided with a pressure plate 532 capable of withstanding wind impact, and the guide sleeve 42 is also provided with an air outlet 425 for pressure relief.

[0066] The airflow introduced by the air inlet 424 is a hot airflow.

[0067] As the hydraulic cylinder 11 drives the forging plate 4 and the guide rod 41 to move up and down, the multiple air inlets 424 evenly opened along the circumference of the guide sleeve 42 begin to introduce hot air flow. The externally heated air is introduced into the guide sleeve 42 to assist the flow and distribution of the lubricating oil. The lubricating oil is heated to reduce its viscosity. The lubricating oil with lower viscosity has better fluidity and is distributed more quickly and evenly in the entire lubrication space 421, thereby improving the lubrication effect.

[0068] Since each rotating blade 53 is provided with a pressure plate 532 capable of withstanding wind impact, when the hot air flow enters through the air inlet 424 and impacts the pressure plate 532 on the rotating blade 53, a driving force is generated to cause the rotating blade 53 to start rotating. The rotation driven by the hot air flow not only promotes the uniform distribution of the lubricating oil in the lubricating space 421, but also enhances the coverage effect of the lubricating oil on the surface of the guide rod 41.

[0069] At the same time, in order to maintain the pressure balance inside the guide sleeve 42 and avoid excessive internal pressure due to the introduction of too much hot air flow, the air outlet 425 on the guide sleeve 42 allows air to flow out, thereby effectively adjusting the pressure difference between the inside and outside of the guide sleeve 42. This prevents the upper bellows 51 and the lower bellows 52 from being damaged due to the continuous increase in air pressure. This ensures that the rotating blades 53 can rotate continuously and stably, and also ensures that the lubricating oil can exert the best lubrication effect under appropriate temperature and pressure conditions.

[0070] The present invention surrounds the guide rod 41 by the upper bellows 51 and the lower bellows 52, thereby ensuring the sealing of the guide rod 41 during the lifting and lowering process of the forging plate 4, preventing the entry of external dust and impurities, keeping the lubricating oil clean and evenly distributed on the surface of the guide rod 41, and avoiding the formation of sludge. Secondly, the multiple balls 423 arranged in the circumferential direction of the guide sleeve 42 are in rolling contact with the guide rod 41, reducing friction, enhancing the smooth operation of the guide rod 41 and reducing wear, thereby ensuring the smooth progress of the forging process.

[0071] As the guide rod 41 moves up and down, the rotating blade 53 in the lubrication space 421 continuously stirs the lubricating oil to ensure that it is evenly distributed and effectively covers the surface of the guide rod 41, further reducing the friction coefficient and reducing the movement resistance. In addition, the sealing rubber ring 431 prevents the lubricating oil from flowing downward to the accumulation on the forging plate 4, avoiding interference caused by the accumulation of lubricating oil, and discharges excess lubricating oil through the oil discharge port 432 to prevent the accumulation and solidification from affecting the movement of the guide rod 41.

[0072] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
