Description

Technical Field

[0001] The invention relates to the technical field of fluid pressure driving, in particular to an oil cylinder driving device for flexible thermal shock. Background Art

[0002] Flexible hot stamping, also known as hot forming or hot stamping, is an advanced metal processing process mainly used for the manufacture of materials such as high-strength steel and aluminum alloys. The process heats the metal blank to a high temperature and then quickly transfers it to a die for stamping and hardening in the die, thereby obtaining high-strength and complex-shaped parts.

[0003] However, the existing cylinder drive device for flexible hot punching has the following shortcomings: 1) When the material is formed by hot stamping, the shape cannot be easily changed after cooling. Traditional equipment does not have the ability of adaptive regulation. In order to ensure the accuracy of the inner shaft extension, manual assistance is required to complete the calibration. This execution method not only leads to poor accuracy control, but also too cumbersome operation; 2) The driving component mainly realizes the extension and retraction of the shaft inside the oil cylinder. In order to soften the metal material, the temperature of the main body needs to be heated to a specified range. During stamping, the preset oil cylinder will be continuously baked by the high-temperature metal, causing the temperature of the oil contained in it to gradually increase. However, due to its own structural limitations, traditional equipment cannot independently suppress high temperature according to the actual situation of the oil body, resulting in a surge in the probability of damage to the entire hydraulic system.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 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.

[0017] 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.

[0018] 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.

[0024] The effect achieved by the entire embodiment 1 is as follows: by presetting the above-mentioned components, the mechanism includes a total of two oil channels, and flow metering parts are reasonably installed at the nodes of the channels, and the penetration effect of the metering parts is utilized to enable it to have two-way metering of oil release and reflux at the same time.

[0025] Embodiment 2, according to Figure 3 and Figure 8-Figure 9 As shown, the high heat treatment mechanism 4 includes a metal convex cover 401.

[0026] The effect achieved by the entire embodiment 2 is as follows: by presetting the above-mentioned components, the mechanism can monitor the temperature of the oil body after circulation in real time by the relevant temperature measuring components when the equipment is running. When it meets the temperature control range, the operation of the relevant 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 be driven to 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 the 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 by high temperature from the inside to the outside, thereby accelerating the high temperature elimination rate and quickly achieving the high temperature suppression effect.

[0027] Embodiment 3, according to Figure 8-Figure 9 As shown, a group of heat-conducting scales 417 are connected to the surface wall of the metal convex cover 401. The high temperature that is reverse-osmotic to the metal convex cover 401 can be discharged from each diverging pipe 408 under the high-speed traction of the motive fan blades 407. The high-temperature treatment mechanism 4 also includes a group of positioning rods 402. A group of positioning rods 402 are installed at the bottom of the oil storage tank 1.

The sensing end of the temperature sensor component 418 is located inside the shunt seat 301.

[0028] The effect achieved by the entire embodiment 3 is: by presetting the above-mentioned components, if the oil body temperature 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 all vertically assembled, the induced airflow 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 channels with the airflow. This effect can effectively avoid high temperature retention, prevent the inhibition of the subsequent cold airflow, and ensure that the oil body temperature control can always be in a relatively efficient state.

[0029] The working principle of the whole equipment is as follows: in the preparation stage, the equipment is first moved to the designated workstation, and a customized bracket is used to support the main body of the equipment, in order to ensure that the bottom of the equipment is hollowed out, and then the external line is connected to the power supply of the equipment to provide energy for multiple electrical components therein, and the oil filling assembly 11 is manually operated. 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, an adapter workpiece is selected and assembled above the additional locking piece 10. The cavity parameters of the oil cylinder body 7 and the pre-obtained stamping depth are used by the external device to set a certain and accurate oil injection amount, and the determined data is written into the flow meter 302 system; In the oil release stage, the driving pump 306 is turned on to drive the booster head 307 to continuously work, and the first filter-type drainage head 308 is used to extract the oil. Prior to this, the first electronic control component 305 has opened the valve member in the oil circuit, and then the oil is diverted through the diverter seat 301, and the oil is continuously transferred to the inside of a corresponding oil cylinder body 7 through the connecting pipe 309, the first delivery pipe 313 and the second delivery pipe 314. As the oil inside the cylinder body rises, the hydraulic pressure in the vacuum chamber also increases, forcing the inner shaft to quickly lift up. During the process, the flow meter 3 02 The internal components calculate the flow rate 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 equipment system through the information line 319, and the first electronic control component 305 and the drive pump 306 are synchronously controlled by the relevant modules. The former is used to close the channel, and the latter is closed to stop the oil extraction. Since the oil channel is closed, there will be no backflow, resulting in pressure relief problems, and the inner shaft of the cylinder body 7 can be accurately extended to a certain depth, and the workpiece connected to the shaft end is fully pressed to the pre-stamping area of ​​the hot metal part, and the structural plasticity is completed after a short stay; During the oil reflux phase, the relevant system modules control the opening of the electronically controlled two-way valve 312 and the second electronically controlled component 318 respectively. The former is used to open the preset airway, and the latter can drive the connected valve components to open the inner channel of the extended reflux component 316. The gas is injected into the interior of the oil cylinder body 7 from the top through the third delivery pipeline 315, forming a reverse thrust from top to bottom, thereby accelerating the discharge of the oil at the lower end of the oil cylinder body 7. Regardless of whether the oil is being released or refluxed, it must pass through the interior of the flow meter 302, and the oil reflux volume can also be measured in real time. The range is determined by the oil flow meter 302. The workpiece at the shaft end of the cylinder body 7 can be completely separated from the hot metal part, but its inner shaft is still in a certain extension state, that is, after meeting the standard, the airway and the inner channel of the extended return part 316 are closed by controlling the electrically controlled two-way valve 312 and the extended return part 316. When the next stamping is performed, the first electrically controlled component 305, the driving pump 306 and the electrically controlled two-way valve 312 are opened, and the oil is injected again, and the gas at the upper end of the cylinder body 7 flows back to the gas tank 311 through the third delivery pipeline 315. The oil is released and refluxed repeatedly in the above manner; During the temperature control stage, after the oil cylinder body 7 has been running for a period of time, the oil body circulating into the diverter seat 301 will continue to heat up under various factors, and its actual temperature value can be monitored in real time by the temperature sensor component 418. If it is close to or exceeds the preset range, the temperature control process is carried out in time, and the compression drive 411 and the blast drive 412 are turned on synchronously. The cold air continuously generated by the former is horizontally injected into the junction box 413 by the third square tube 415, and the high-speed airflow generated by the latter can be longitudinally injected into the junction box 413 by the second square tube 414, so as to achieve the purpose of carrying the cold air downward at a high speed, and then continuously transported by the fourth square tube 416 and the first square tube 410, the high-speed cold airflow can be continuously introduced into the metal convex cover 40 from the bevel joint 409. 1, contacts the induced blades 407 that blow at a fixed point, and can obtain rotational power. By utilizing the physical properties of the roller bearing member 403, the induced blades 407 on the external ring sleeve 406 can rotate at a high speed inside the metal convex cover 401, and quickly diffuse the cold airflow to the inside of the metal convex cover 401. The low temperature of the airflow gradually penetrates into the body of the metal convex cover 401, and is quickly locked by each heat-conducting scale 417, and further completes the diffusion of the cold air. If the temperature of the oil body is too high, part of the high temperature will reversely penetrate into the inside of the metal convex cover 401 and merge with the cold airflow inside it. The swinging effect of the induced blades 407 can continuously push the airflow carrying the high temperature into the designated diverging pipe 408, and further complete the release from the bottom of the equipment.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
