Description

Technical Field

[0001] The present invention relates to the field of forging presses, and specifically to an automotive control arm forging press for dust prevention and lubrication of guide rods. Background Art

[0002] As a key component connecting the wheel and the vehicle body, the automotive control arm plays an important role in transmitting driving force, braking force, and road surface feedback. It is manufactured by forging process, precisely controlling the plastic deformation of metal materials under high temperature and high pressure. In the existing technology of automotive control arm forging presses, the dust prevention and lubrication management of the guide rods have not been fully optimized. There is a lack of effective protective measures to prevent the dust floating in the workshop from entering the guide rod area, which not only pollutes the lubricating oil, but also accelerates the aging process of the lubricating oil and reduces its lubrication efficiency.

[0003] Currently, a forging press for an automotive U-shaped control arm forging disclosed in the Chinese authorized publication number CN115673208B includes a machine body. A support box is fixedly connected to the back of the machine body, a bottom plate is fixedly connected to the top of the machine body, a working box is fixedly connected to the top of the support box, a lifting mechanism is arranged in the working box, an oil leveling mechanism is arranged on the top of the machine body, and a descaling mechanism and a jetting mechanism are arranged in the lifting mechanism.

[0004] According to the above patent, the patent has the function of evenly applying the lubricating oil on the guide rod through the oil leveling mechanism, reciprocally circulating the descaling work on the bottom end of the guide rod through the descaling mechanism, and blowing out the removed scale through the jetting mechanism. However, as dust continuously accumulates on the guide rod, even after the preliminary cleaning by the sponge pad, there may still be some fine particles remaining and mixing with the lubricating oil to form sludge, increasing the frictional resistance during the movement of the guide rod, thereby affecting the smooth operation of the forging process. Therefore, there is a need for an automotive control arm forging press that integrates efficient dust prevention, automatic cleaning, and intelligent lubrication management to reduce the pollution of the guide rod by dust and prevent the formation of sludge on the guide rod. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, an automotive control arm forging press for dust prevention and lubrication of guide rods is provided. The guide rod is surrounded by an upper bellows and a lower bellows, ensuring the sealing performance of the guide rod during the lifting and lowering of the forging plate. As the guide rod moves up and down, the balls on the guide sleeve rollingly contact the guide rod, reducing the frictional force. At the same time, the rotating blades continuously stir the lubricating oil to ensure its uniform distribution and effective coverage of the surface of the guide rod, reducing the moving resistance.

[0006] To solve the problems of the prior art, the present invention provides an automotive control arm forging press for dust-proof lubrication of guide rods, which includes a machine body. A bottom plate for placing the control arm and a forging press plate for pressing the control arm are provided on the machine body. A pair of vertically upward extending guide rods are symmetrically provided on the forging press plate. Guide sleeves sleeved on each of the guide rods are provided on the machine body. A dust-proof lubrication assembly for preventing sludge accumulation on the guide rods is provided on each of the guide sleeves. The dust-proof lubrication assembly includes an upper bellows and a lower bellows. The upper bellows is connected between the upper end of the guide rod and the guide sleeve, and the lower bellows is connected between the lower end of the guide rod and the guide sleeve. A sealed space surrounding the guide rod is formed among 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 injection port communicating with the lubrication space is opened on the guide sleeve. A plurality of balls in rolling contact with the guide rod are evenly distributed along the circumferential direction of the guide sleeve.

[0007] Preferably, the dust-proof lubrication assembly further includes a rotating blade disposed in the lubrication space. The rotating blade can rotate around the guide rod in the lubrication space. In the working state of the rotating blade, the lubricating oil in the lubrication space is in a continuously stirred state, and at the same time, the lubricating oil is evenly smeared on the surface of the guide rod.

[0008] Preferably, a conical base coaxial with the lower end of the guide sleeve is provided. A sealing rubber ring sleeved on the guide rod is provided on the conical base to block the downward flow and accumulation of lubricating oil on the forging press plate.

[0009] Preferably, an annular groove for rotatably arranging the balls is formed along the circumferential direction of the inner wall of the guide sleeve. The oil injection port communicating with the annular groove is opened on the guide sleeve. All the balls can move along the path of the annular groove through the oil injection port.

[0010] Preferably, a rotating ring sleeve coaxial with the guide sleeve is provided in the guide sleeve. Embedding holes for each ball to be embedded therein are formed on the rotating ring sleeve. A clamping groove for clamping with the rotating blade is formed at the lower end of the rotating ring sleeve. When the rotating blade rotates, the rotating ring sleeve drives all the balls to rotate synchronously.

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

[0012] Preferably, an oil drain port for draining the excess lubricating oil is opened on the conical base.

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

[0014] Preferably, a plurality of air inlets are evenly arranged along the circumferential direction of the guide sleeve. A pressure-receiving plate capable of withstanding wind impact is provided on each rotating blade. An air outlet for pressure relief is also provided on the guide sleeve.

[0015] The beneficial effects of this application compared with the prior art are as follows:

[0016] 1. In the present invention, during the lifting process of the forging plate, the upper bellows and the lower bellows seal the guide rod, preventing external dust and impurities from entering the working area, ensuring that the lubricating oil can be well maintained in the lubricating space and evenly distributed on the surface of the guide rod, and avoiding the situation where the lubricating oil contacts dust to form sludge.

[0017] As the guide rod moves with the forging plate, a plurality of ball bearings arranged in the circumferential direction of the guide sleeve rollingly contact the guide rod, reducing the friction force, 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 phenomenon of the guide rod getting stuck or worn due to impurities, improving the efficiency of the forging process.

[0018] 2. In the present invention, through the rotation of the rotating blades around the guide rod in the lubricating space, the lubricating oil is continuously agitated, ensuring that the oil quality is evenly distributed and preventing sedimentation or stratification. It can more effectively cover and evenly coat the entire surface of the guide rod, forming a protective film, further reducing the friction coefficient in contact with the ball bearings and reducing the risk of the guide rod being blocked during its up and down movement.

[0019] In addition, the sealing rubber ring effectively blocks the downward flow of the lubricating oil 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 continuously obtains sufficient lubrication.

[0020] 3. In the present invention, the lubricating oil is injected into the annular groove through the oil injection port to ensure that the lubricating oil can evenly cover the surface of the ball bearings and, along with the synchronous rotation of the rotating ring sleeve, bring the lubricating oil to the contact surface between the ball bearings and the guide rod, reducing the friction force and preventing wear. The oil drain port effectively discharges the excess lubricating oil to prevent its accumulation and solidification from affecting the movement of the guide rod.

[0021] Secondly, hot air flow is introduced into the interior of the guide sleeve through the air inlets, reducing the viscosity of the lubricating oil and enhancing its fluidity. At the same time, the rotating blades rotate under the drive of the hot air flow, further promoting the even coating and flow of the lubricating oil, avoiding local accumulation or lack of the lubricating oil, and improving the smoothness of the movement of the guide rod following the forging plate.

Specific embodiments

[0036] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] See Figures 1 - 5 As shown, an automotive control arm forging press for dust-proof lubrication of a guide rod includes a body 1, a bottom plate 3 for placing a control arm 2 is provided on the body 1, and a forging plate 4 for pressing the control arm 2 is provided. A pair of vertically upwardly extending guide rods 41 are symmetrically provided on the forging plate 4, and guide sleeves 42 sleeved on each of the guide rods 41 are provided on the body 1. A dust-proof and lubricating component 5 for preventing sludge from accumulating on the guide rod 41 is provided on each of the guide sleeves 42. A lubrication space 421 capable of injecting lubricating oil therein is formed between the guide sleeve 42 and the guide rod 41. An oil injection port 422 communicating with the lubrication space 421 is opened on the guide sleeve 42, and a plurality of balls 423 in rolling contact with the guide rod 41 are uniformly distributed along the circumferential direction of the guide sleeve 42.

[0038] A hydraulic cylinder 11 for driving the forging plate 4 to move up and down is provided on the body 1.

[0039] During the operation of the automotive control arm 2 forging press, first, the control arm 2 to be processed is placed on the bottom plate 3 to prepare for forging operation. When the forging process starts, the hydraulic cylinder 11 starts to work, driving the forging plate 4 and its connected guide rod 41 to move downward along the guide sleeve 42. During this process, since the lubrication 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 injection port 422 on the guide sleeve 42, the guide rod 41 can be fully lubricated during each up and down movement. At the same time, a plurality of 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 force, but also further enhances the smooth operation of the guide rod 41 and reduces the possibility of wear.

[0040] As the forging plate 4 gradually approaches the control arm 2, the pressure it exerts gradually increases until it reaches a predetermined pressure value, completing the forging operation on the control arm 2. During the forging process, dust and lubrication measures effectively avoid the jamming or wear of the guide rod 41 caused by impurities such as dust and debris. In addition, the existence of the lubrication space 421 and the application of the ball 423 greatly reduce the frictional resistance between the guide rod 41 and the guide sleeve 42, ensuring the smooth progress of the forging process.

[0041] After forging is completed, the hydraulic cylinder 11 drives the forging plate 4 and the guide rod 41 to retract to the initial position. At this time, due to the continuous function of the dust and lubrication component 5 provided in the guide sleeve 42, even after long-term use, the surface of the guide rod 41 can be kept clean and smooth. This not only improves work efficiency but also reduces maintenance costs and failure rates.

[0042] See Figures 1 - 5 As shown, the dust and lubrication component 5 includes an upper bellows 51 and a lower bellows 52. 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. A sealed space that surrounds the guide rod 41 is formed among the upper bellows 51, the lower bellows 52, and the guide sleeve 42.

[0043] When the guide rod 41 is installed in the guide sleeve 42, the upper bellows 51 and the lower bellows 52 in the dust and lubrication component 5 play a dust-proof effect on the guide rod 41. A completely sealed space is formed among the upper bellows 51, the lower bellows 52, and the guide sleeve 42, tightly surrounding the guide rod 41. It can not only effectively prevent external pollutants such as dust and impurities from entering the working area of the guide rod 41 but also ensure that the lubricating oil can be well maintained in the sealed space and distributed on the surface of the guide rod 41.

[0044] When the hydraulic cylinder 11 drives the forging plate 4 and the guide rod 41 to move up and down, the bellows expand and contract accordingly but always maintain their sealing performance, preventing any external factors that may affect the smooth operation of the guide rod 41 from intruding. During this process, the lubricating oil in the sealed space continuously provides necessary lubrication for the guide rod 41, reducing friction and at the same time avoiding wear problems caused by dust or debris, ensuring the smooth progress of the entire forging process.

[0045] See Figure 1 and Figures 5 - 11 As shown, the dust and lubrication component 5 further includes a rotating blade 53 provided in the lubrication space 421. 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 at the same time, the lubricating oil is evenly smeared on the surface of the guide rod 41.

[0046] 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,

[0047] 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.

[0048] See also Figures 5 - 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.

[0049] 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.

[0050] 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.

[0051] See also Figure 6 , Figure 7 and Figure 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.

[0052] When the guide rod 41 moves up and down along with the forging press plate 4 and moves along the guide sleeve 42, lubricating oil is injected into the lubricating space 421 through the oil injection port 422 on the guide sleeve 42 that communicates with the annular groove 4231. The oil injection port 422 not only provides necessary lubricating oil supply for the lubricating space 421, but also ensures that all the balls 423 can move along the path of the annular groove 4231 and pass through the oil injection port 422 due to the position where the oil injection port 422 is opened.

[0053] Whenever the balls 423 move cyclically to the position of the oil injection port 422, all the balls 423 will come into contact with the newly injected lubricating oil, making the contact between the balls 423 and the surface of the guide rod 41 remain continuously smooth. It ensures that the lubricating oil can be continuously and evenly distributed between the balls 423 and the guide rod 41, effectively reducing the friction force and preventing wear, and ensuring the smooth operation of the guide rod 41 and extending its service life.

[0054] See Figures 6 - 12 As shown, a rotating ring sleeve 54 coaxial with it is provided in the guide sleeve 42. The rotating ring sleeve 54 has embedding holes for each ball 423 to be embedded therein. The lower end of the rotating ring sleeve 54 has a clamping groove 5421 that is clamped 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.

[0055] 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 opened on the lower ring body 542.

[0056] When the rotating ring sleeve 54 is driven to rotate by the rotating blade 53, all the balls 423 embedded therein also enter a synchronous rotation state. The rotation action of the rotating ring sleeve 54 helps to evenly bring the newly injected lubricating oil through the oil injection port 422 to the surface of the balls 423, ensuring the continuity of the lubricating effect between the balls 423 and the guide rod 41.

[0057] While reducing the friction force between the guide rod 41 and the balls 423, it also promotes the uniform distribution of the lubricating oil in the entire lubricating space 421.

[0058] See Figure 6 and Figure 7 As shown, gaps are left between the rotating ring sleeve 54 and the guide sleeve 42 and the guide rod 41 respectively, which can allow the lubricating oil to flow downward.

[0059] 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 balls 423 to provide necessary lubrication, but also slowly flows downward along the gaps between the rotating ring sleeve 54 and the guide sleeve 42 and the guide rod 41. This enables the lubricating oil to continuously flow into the lubricating space 421, ensuring the comprehensiveness and continuity of the lubricating effect.

[0060] During the rotation of the rotating collar 54, the lubricating oil is continuously brought to the contact surface between the ball 423 and the guide rod 41, and flows evenly along the gap, thus avoiding the accumulation or lack of lubricating oil at a single position. This not only ensures the low-friction movement between the ball 423 and the guide rod 41, but also promotes the balanced distribution of the lubricating oil within the entire lubrication space 421. It helps prevent the accumulation of lubricating oil in one place and avoids the performance degradation problem caused by the accumulation of sludge lubricating oil.

[0061] See Figure 6 and Figure 7 As shown, the inverted conical base 43 is provided with an oil drain port 432 for discharging the excess lubricating oil.

[0062] During the operation of the forging press of the automotive control arm 2, as the lubricating oil is injected through the oil injection port 422 and flows downward along the gap between the rotating collar 54 and the guide sleeve 42 and the guide rod 41, excess lubricating oil will inevitably be generated within the lubrication space 421. If the excess lubricating oil is not handled, it may accumulate, and over time, it will affect the up and down movement of the guide rod 41 due to solidification. When the lubricating oil has fully acted within the lubrication space 421, the excess lubricating oil will naturally flow to the bottom due to gravity and be pumped out through the connection of the oil drain port 432 to the pump body.

[0063] The oil drain port 432 not only serves to discharge the excess lubricating oil, but also helps maintain the cleanliness of the lubrication space 421 and prevents the unnecessary accumulation of lubricating oil inside. It not only ensures the optimization of the lubrication effect, but also avoids the waste of lubricating oil and the possible operational interference caused by the accumulation of lubricating oil.

[0064] See Figures 6 - 11 and Figure 13 As shown, a plurality of the rotating blades 53 are evenly distributed along the circumferential direction of the guide rod 41 within the lubrication space 421, and the guide sleeve 42 is provided with a bearing 531 connecting all the rotating blades 53.

[0065] The rotational movement of the rotating blades 53 helps to continuously update 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 blades 53 rotate continuously, enabling the lubricating oil to cover the entire surface of the guide rod 41 and form a continuous and uniform protective film. This makes the contact between the guide rod 41 and the ball 423 smoother.

[0066] In addition, the rotating blades 53 also help to avoid the problem of local accumulation of lubricating oil within the lubrication space 421. By continuously agitating the lubricating oil, the rotating blades 53 can prevent the excessive accumulation or stratification of lubricating oil in certain areas, ensuring the quality and effectiveness of the lubricating oil.

[0067] See Figure 6 、 Figure 7 and Figure 13 As shown, a plurality of air inlets 424 are evenly arranged on the guide sleeve 42 along its circumferential direction. A pressure-receiving plate 532 capable of withstanding wind impact is provided on each rotary vane 53. An air outlet 425 for pressure relief is also provided on the guide sleeve 42.

[0068] The air flow introduced by the air inlets 424 is hot air flow.

[0069] As the hydraulic cylinder 11 drives the forging plate 4 and the guide rod 41 to move up and down, a plurality of air inlets 424 evenly arranged on the guide sleeve 42 along its circumferential direction start to introduce hot air flow. The externally heated air is introduced into the interior of 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 more quickly and evenly distributed in the entire lubricating space 421, thereby improving the lubrication effect.

[0070] Since a pressure-receiving plate 532 capable of withstanding wind impact is provided on each rotary vane 53, when the hot air flow enters through the air inlets 424 and impacts the pressure-receiving plate 532 on the rotary vane 53, a driving force is generated to cause the rotary vane 53 to start rotating. The rotation mode 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 covering effect of the lubricating oil on the surface of the guide rod 41.

[0071] At the same time, in order to maintain the pressure balance inside the guide sleeve 42 and prevent the internal pressure from being too high 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. Avoiding damage to the upper bellows 51 and the lower bellows 52 due to continuous increase in air pressure. It not only ensures that the rotary vane 53 can rotate continuously and stably, but also ensures that the lubricating oil can exert the best lubrication effect under appropriate temperature and pressure conditions.

[0072] In the present invention, the guide rod 41 is surrounded by the upper bellows 51 and the lower bellows 52, ensuring the sealing performance of the guide rod 41 during the lifting and lowering process of the forging plate 4, preventing external dust and impurities from entering, keeping the lubricating oil clean and evenly distributed on the surface of the guide rod 41, and avoiding the formation of sludge. Secondly, a plurality of balls 423 arranged on the circumferential direction of the guide sleeve 42 are in rolling contact with the guide rod 41, reducing the friction force, enhancing the smooth operation of the guide rod 41 and reducing wear, ensuring the smooth progress of the forging process.

[0073] As the guide rod 41 moves up and down, the rotation of the rotary blade 53 in the lubrication space 421 continuously agitates the lubricating oil, ensuring its uniform distribution and effective coverage of the surface of the guide rod 41, further reducing the friction coefficient and the moving resistance. In addition, the sealing rubber ring 431 prevents the lubricating oil from flowing downward and accumulating on the forging plate 4, avoiding the interference caused by the accumulation of lubricating oil, and discharging the excess lubricating oil through the oil drain port 432 to prevent the accumulation and solidification from affecting the movement of the guide rod 41.

[0074] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
