Description

Technical Field

[0001] The present invention relates to the technical field of fluid pressure drive, and particularly to an oil cylinder drive device for flexible hot stamping. Background Art

[0002] Flexible hot stamping, also known as hot forming or hot stamping forming, is an advanced metal processing technology mainly used in the manufacturing of materials such as high-strength steel and aluminum alloy. In this process, the metal blank is heated to a high temperature and then quickly transferred to the mold for stamping and forming, and is cooled and hardened in the mold to obtain high-strength and complex-shaped parts.

[0003] However, the existing oil cylinder drive devices for flexible hot stamping have the following deficiencies:

[0004] 1) When the material is formed by hot stamping and cooled, the shape cannot be easily changed. Traditional equipment does not have the ability of adaptive regulation. To ensure the telescopic accuracy of the inner shaft, manual assistance is required to complete the calibration. This execution method not only results in poor accuracy control but also is too cumbersome to operate.

[0005] 2) The driving component mainly realizes the telescopic movement of the inner shaft of the oil cylinder. To soften the metal material, the temperature of the main body needs to be heated to a specified range. During stamping, it is preset that the oil cylinder will be continuously baked by the high-temperature metal, resulting in a gradual increase in the temperature of the contained oil body. However, due to the limitation of its own structure, traditional equipment cannot independently suppress high temperature according to the actual situation of the oil body, resulting in a sharp increase in the probability of damage to the entire hydraulic system.

[0006] Therefore, we propose an oil cylinder drive device for flexible hot stamping to solve the problems raised above. Summary of the Invention

[0007] The purpose of the present invention is to provide an oil cylinder drive device for flexible hot stamping. By setting a self-checking metering mechanism, the mechanism includes two oil passage channels in total, and a flow metering component is reasonably assembled at the passage node.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention sets a self-checking metering mechanism, which includes two oil passages, and reasonably assembles flow metering parts at the passage nodes. By utilizing the penetration effect of the metering parts, it can simultaneously have two-way metering of oil release and reflux. In the initial state, according to the set oil cylinder specifications and the preset stamping depth, the audit range of the metering parts is reasonably set. The oil release adopts the method of mechanical assisted pressurization, and the oil reflux is assisted by reverse air pressure. Under the joint cooperation of multiple valve components, the telescopic length of the shaft in the oil cylinder can be accurately controlled. On the one hand, a relatively reasonable stamping intensity can ensure the integrity of the pressure-bearing part of the hot metal part and improve the subsequent forming effect. On the other hand, a reasonable retraction amount can avoid the need for the shaft in the oil cylinder to repeatedly operate to the maximum extent, reduce mechanical fatigue and component friction, and suppress the temperature rise of the oil to a certain extent.

[0022] 2. The present invention sets a high heat treatment mechanism, and the operation of related components can continuously complete the release of high-speed airflow and cold air. Since the convex body is completely placed in the oil body, the combined high-speed cold airflow can be injected into the interior of the convex body at a fixed point, forcing the mechanical components to operate, and the cold air can flow in a circular shape inside the convex body. The low temperature acts on various areas of the convex body, and the heat-conducting component body is quickly cooled by physical penetration, and then the low-temperature release is further completed. This method completes the low-temperature transfer by contact, and reasonably constructs a temperature control platform to ensure that the oil body can cover a large area on the low-temperature permeable component. The oil body can be neutralized at high temperature from the inside to the outside, thereby accelerating the high-temperature elimination rate and quickly achieving the high-temperature suppression effect.

[0023] 3. The present invention sets a high heat treatment mechanism. If the temperature of the oil body is too high, part of the high temperature will seep back into the convex body. Since the fan blades contained in the mechanical parts are vertically assembled, the airflow induced by them rotates in a circular shape inside the convex body, and part of the airflow will be thrown into the equidistantly set channels. Therefore, the heat that penetrates into it will also be quickly discharged from the corresponding channel with the airflow. This effect can effectively avoid high temperature retention and prevent the subsequent cold airflow from being inhibited, thereby ensuring that the temperature control of the oil body can always be in a relatively efficient state.

[0037] The effects achieved by the entire Embodiment 1 are as follows: By presetting the above components, the mechanism includes a total of two oil passage channels, and a flow metering component is reasonably assembled at the passage node. Utilizing the through effect of the metering component, it enables bidirectional metering of both oil release and reflux. In the initial state, according to the preset cylinder specifications and the preset stamping depth, the audit range of the metering component is reasonably set. The oil release adopts the method of mechanical auxiliary pressurization, and the oil reflux is assisted by reverse air pressure. With the joint cooperation of multiple valve components, the telescopic length of the inner shaft of the cylinder can be accurately controlled. On the one hand, a relatively reasonable punching force can ensure the integrity of the pressed part of the hot metal part and improve the subsequent forming effect. On the other hand, a reasonable retraction amount can avoid the need for the inner shaft of the cylinder to repeatedly operate to the maximum extent, reduce mechanical fatigue and component friction, and inhibit the oil temperature rise to a certain extent.

[0038] Embodiment 2, according to Figure 3 and Figures 8 - 9 As shown, the high-temperature treatment mechanism 4 includes a metal convex mask 401. The body of the metal convex mask 401 can be deeply inserted into the storage oil tank 1 to fully contact the internal oil body. An external ring sleeve 406 is provided inside the metal convex mask 401. A group of driving fan blades 407 are connected to the outer surface wall of the external ring sleeve 406. When high-speed cold air is continuously injected into the metal convex mask 401, it can trigger the rotation of the driving fan blades 407. A group of heat-conducting scales 417 are connected to the surface wall of the metal convex mask 401. The low temperature can diffuse to the oil body layer by layer through the heat-conducting scales 417. The internal of the metal convex mask 401 is fixedly connected with an inclined surface joint 409. The outer wall of the inclined surface joint 409 is connected with a first square pipe 410. On one side of the outer wall of the storage oil tank 1, a compression driving part 411 and a blowing driving part 412 are respectively fixedly installed. A confluence box 413 is additionally installed on one side of the outer wall of the storage oil tank 1. The output end of the compression driving part 411 is fixedly connected with a third square pipe 415. The exhaust end of the blowing driving part 412 is connected to the second square pipe 414. The exhaust end of the second square pipe 414 is connected to the top of the confluence box 413 and is connected to the inside of the confluence box 413. The cold air discharge end of the third square pipe 415 is connected to the side of the confluence box 413. The bottom of the confluence box 413 is connected with a fourth square pipe 416. The fourth square pipe 416 is connected to the end of the first square pipe 410.

[0039] The effect achieved by the entire Embodiment 2 is as follows: By presetting the above components, when the device is running, the relevant temperature-measuring components can monitor the temperature of the circulated oil body in real time. When the temperature meets the temperature control range, the relevant components can continuously release high-speed air flow and cold air. Since the convex body is completely placed in the oil body, the combined high-speed cold air flow can be injected into the convex body at a fixed point, forcing the mechanical components to operate. The induced cold air can flow annularly inside the convex body, and the low temperature acts on each area of the convex body. Through physical penetration, the temperature-conducting part body can be quickly cooled, and then the low temperature release can be further completed. This method completes the low-temperature transfer through contact, reasonably constructs a temperature control platform, ensures that the oil body can cover the low-temperature permeable part in a large area, and the oil body can neutralize the high temperature from the inside out, thereby accelerating the high-temperature elimination rate and quickly achieving the inhibitory effect on high temperature.

[0040] Embodiment 3, according to Figures 8 - 9 As shown, a group of heat-conducting scales 417 are connected to the surface of the metal convex mask 401. The high temperature that has penetrated into the metal convex mask 401 can be discharged from each diverging duct 408 under the high-speed driving of the driving fan blade 407. The high-temperature treatment mechanism 4 further includes a group of positioning rods 402. A group of positioning rods 402 are all installed at the bottom of the oil storage tank 1. A roller bearing part 403 is sleeved between the outer surfaces of the group of positioning rods 402. A solid rod 404 is inserted into the inner surface of the inner shaft of the roller bearing part 403. A linkage structure 405 is sleeved on the outer surface of the solid rod 404. The linkage structure 405 is connected to the inner wall of the external ring sleeve 406. A temperature sensing component 418 is arranged on one side of the outer wall of the flow dividing seat 301. The sensing end of the temperature sensing component 418 is located inside the flow dividing seat 301.

[0041] The effect achieved by the entire Embodiment 3 is as follows: By presetting the above components, if the oil body temperature value is too high, part of the high temperature will penetrate back into the convex body. Since the fan blades included in the mechanical parts are all vertically assembled, the induced air flow will rotate annularly inside the convex body, and part of the air flow will be thrown into the equidistantly set channels. Therefore, the heat that has penetrated into them will also be quickly discharged from the corresponding channels along with the air flow. This effect can effectively avoid the retention of high temperature, prevent the inhibition of the subsequent incoming cold air flow, and ensure that the oil body temperature control can always be in a relatively efficient state.

[0042] The working principle of the whole device is as follows: In the preparation stage, the device is first moved to the designated working station, and the main body of the device is supported by a customized bracket to ensure that the bottom of the device is hollow. Then, the external line is connected to the device power supply to provide energy for multiple electrical components inside. Manually operate the oil injection component 11, and according to the actual specifications of the oil storage tank 1, an appropriate amount of hydraulic oil can be injected into the oil storage tank 1. According to the stamping requirements, select a suitable workpiece and assemble it above the locking component 10. Use external equipment to set a certain accurate oil injection amount based on the cavity parameters of the cylinder body 7 and the pre-obtained stamping depth. The determined data is written into the flow meter 302 system;

[0043] In the oil release stage, turn on the drive pump 306 to drive the booster head 307 to continuously do work. The first filter type drain head 308 is used to extract the oil. Before this, the first electronic control component 305 has opened the valve parts in the set oil circuit. Then, the oil is shunted through the shunt seat 301 and continuously transferred to the inside of a corresponding cylinder body 7 through the connecting pipe 309, the first conveying pipe 313, and the second conveying pipe 314. As the oil inside it rises, the hydraulic pressure in the vacuum cavity also increases, forcing the inner shaft to quickly lift. During the process, the internal components of the flow meter 302 calculate the throughput in real time through the channel cross-sectional area and the oil flow rate. When the value is about to approach the set range, the signal can be shared to the device system through the information line 319, and the relevant modules synchronously control the first electronic control component 305 and the drive pump 306. The former is used to close the channel, and the latter closes to stop the oil extraction. Since the oil channel is closed, there will be no problem of backflow and pressure relief. The inner shaft of the cylinder body 7 can accurately extend a certain depth, and the workpiece connected to the shaft end can fully press on the pre-stamping area of the hot metal part, and stay briefly to complete the structural plasticity;

[0044] In the oil return stage, the relevant system modules respectively control the opening of the electro-hydraulic two-way valve 312 and the second electronic control component 318. The former is used to open the preset air channel, and the latter can drive the connected valve parts to open the channel in the extended return part 316. The gas is injected into the inside of the cylinder body 7 from the top through the third conveying pipe 315 to form a reverse thrust from top to bottom, thereby accelerating the discharge of the oil at the lower end of the cylinder body 7. Whether the oil is in the release or return state, it needs to pass through the inside of the flow meter 302. Therefore, the oil return amount can also be measured in real time. The range only needs to ensure that the workpiece at the shaft end of the cylinder body 7 can be completely separated from the hot metal part. However, its inner shaft is still in a certain extended state. When it is about to meet the standard, by controlling the electro-hydraulic two-way valve 312 and the extended return part 316, the air channel and the channel in the extended return part 316 are closed. When the next stamping is carried out, turn on the first electronic control component 305, the drive pump 306, and the electro-hydraulic two-way valve 312 to inject oil again, and the gas at the upper end of the cylinder body 7 returns to the gas tank 311 through the third conveying pipe 315. The oil release and return are repeated in the above way;

[0045] During the temperature control stage, after the oil cylinder body 7 has been operating for a period of time, the oil body circulating into the flow dividing seat 301 will continuously heat up under various factors. Its actual temperature value can be monitored in real time by the temperature sensing component 418. If it approaches or exceeds the preset range, the temperature control process will be carried out in a timely manner. The compression driving part 411 and the air blowing driving part 412 will be turned on synchronously. The cold air continuously generated by the former is horizontally injected into the confluence box 413 through the third-party pipe 415, and the high-speed air flow generated by the latter can be longitudinally injected into the confluence box 413 through the second-party pipe 414 to achieve the purpose of carrying the cold air down at high speed. Then, through the continuous transportation of the fourth-party pipe 416 and the first-party pipe 410, the high-speed cold air flow can be continuously introduced into the interior of the metal convex mask 401 from the inclined surface joint 409. When it contacts the driving fan blade 407 that blows at a fixed point, it can obtain rotational power. Utilizing the physical characteristics of the roller bearing part 403, the driving fan blade 407 on the outer ring sleeve 406 can rotate at high speed inside the metal convex mask 401, quickly spreading the cold air flow fully inside the metal convex mask 401. The low temperature of the air flow gradually penetrates into the body of the metal convex mask 401 and is quickly locked by each heat conduction scale 417, further completing the diffusion of the cold air. If the temperature of the oil body is too high, part of the high temperature will back-seep into the interior of the metal convex mask 401 and merge with the cold air flow inside it. The swinging effect of the driving fan blade 407 can continuously push the air flow carrying the high temperature into the designated divergence pipe 408, and further release it from the bottom of the equipment.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
