Description

Technical Field

[0001] This invention relates to the field of grinding wheel production technology, specifically to a device and method for efficient homogenization of the loose-pack structure of large blanks based on dynamic control technology. Background Technology

[0002] In powder metallurgy, ceramic body manufacturing, and other forming processes based on powder raw materials, the "green body" refers to the "semi-finished blank" after the powder raw material has undergone preliminary processes such as "material distribution and pre-pressing" but has not yet undergone final sintering / curing. "Loose packing" corresponds to the state of the green body, at which point the powder particles are only initially piled up by slight external force (such as gravity distribution), and there are a large number of pores between the particles, without forming a dense bond. Therefore, the "loose packing structure of the green body" is the internal structure of the green body formed by the accumulation of particles and has a loose porous structure in the preliminary forming stage of the powder raw material. It is the "source link" that determines the uniformity of the structure and mechanical properties of the final product (such as a grinding wheel). Taking a grinding wheel as an example: the loose packing structure of the grinding wheel green body is the loose particle accumulation structure of the mixed powders such as corundum sand and binder (resin / ceramic powder), which are laid into the mold by a feeding device and go through the combing and scraping processes, but have not undergone final pressing.

[0003] The uniformity of the loose structure of the grinding wheel blank is mainly controlled by the uniformity of component distribution and the uniformity of pore distribution. Component uniformity refers to whether different components in the mixed powder (such as abrasive particles and binder powder in a grinding wheel) are locally aggregated or regionally segregated within the blank. For example, if "binder powder clumping" occurs locally in the grinding wheel blank, insufficient abrasive will result in "insufficient grinding force" in that area after subsequent curing; if abrasive particles are locally aggregated, insufficient binder will lead to "abrasive detachment".

[0004] The porosity distribution in a loosely packed state is greatly affected by external forces. The feeding speed, feeding height, and feeding sequence during the material feeding process all lead to differences in porosity distribution in different areas of the blank. After subsequent sintering or curing, "large pores" result in insufficient local strength of the finished product, while "excessively dense small pores" prevent gas from escaping during sintering, forming internal cracks. The uneven quality caused by uneven porosity increases the static imbalance value of the grinding wheel, ultimately affecting the performance of the grinding wheel.

[0005] Currently, small grinding wheels (diameter ≤ 500mm, thickness ≤ 100mm) have a thin loose packing structure and a short material feeding time; basic combing and scraping structures are sufficient to meet the requirements for uniform loose packing structure in their blanks. Large grinding wheels (diameter > 500mm, thickness > 100mm) have a loose packing thickness that can reach twice the thickness of the finished product, resulting in a longer material feeding time. Furthermore, when the material enters the mold, the mold itself is rotating, and the different order, height, and angle of material entry lead to variations in porosity distribution.

[0006] In the prior art, for example, Chinese utility model patent CN 214636919 U discloses a scraping mechanism for a vertical mill, including an intermediate cylinder of the mill and a grinding disc and grinding rollers located inside the intermediate cylinder. A scraping mechanism is provided on the grinding track of the grinding disc between two adjacent grinding rollers. The scraping mechanism includes a scraper that is arc-shaped when viewed from above, with wedge-shaped ends. The lower edge of the scraper is close to the inner surface of the grinding track. One end of the scraper is located at or near the outer side of the grinding track, and the other end is located at or near the middle position in the width direction of the grinding track, facing the direction of material movement. Although the above solution can achieve the function of scraping material, it cannot actively comb the material or automatically control it.

[0007] Therefore, the combing and scraping processes in the large grinding wheel forming stage need to be able to effectively identify the state of the loose blank and improve the uniformity of the loose material structure in real time. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art, effectively identify the state of loosely packed embryos, improve the uniformity of the loosely packed material structure in real time, and provide a device and method for efficient homogenization of loosely packed tissue structure of large embryos based on dynamic control technology.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A highly efficient homogenization device for large embryonic loose tissue based on dynamic control technology, comprising: A material combing and scraping mechanism includes a scraper and a material combing fork located at one end of the scraper, used to perform lifting and lowering actions within the grinding ring of a press wheel to comb and loosen materials; A sensing mechanism, installed on the combing and scraping mechanism, is used to detect the loose state of the material; A lifting mechanism, connected to the combing and scraping mechanism, is used to drive the combing and scraping mechanism to perform lifting and lowering movements; A dynamic control mechanism is electrically connected to both the sensing mechanism and the lifting mechanism, and is used to control the operation of the lifting mechanism according to the material loosening state detected by the sensing mechanism.

[0010] This invention detects the loosening state of materials through a sensing mechanism, and regulates the operation of the lifting mechanism according to the loosening state detected by the sensing mechanism through a dynamic control mechanism. This, in turn, controls the combing and scraping mechanism to perform lifting actions to comb and loosen the materials, thereby achieving efficient and uniform loosening of large preforms, improving loosening efficiency and automation level.

[0011] Preferably, it further includes: The feeding mechanism is used to feed materials into the grinding ring of the press grinding wheel; The dynamic control mechanism is further electrically connected to the feeding mechanism and is used to control the start and stop of the feeding mechanism according to the material loosening state.

[0012] Preferably, the combing and scraping mechanism further includes a swing arm mechanism, wherein the end of the scraper away from the combing fork is connected to the swing arm mechanism, and the bottom of the swing arm mechanism is connected to the lifting mechanism.

[0013] Preferably, the angle between the scraper surface direction and the radial line of the press grinding wheel is 5° to 30°.

[0014] Preferably, the lifting mechanism includes a vertical lifting rod and a drive unit, wherein the drive unit is used to drive the vertical lifting rod to lift and lower, and the drive unit is an electric push rod.

[0015] Preferably, the sensing mechanism is a force sensor, which is installed on the scraper of the combing and scraping mechanism to detect the pressure of the material on the scraper.

[0016] By using mechanical sensors to detect the force between the material and the combing mechanism, dynamic control of the mechanism can be achieved.

[0017] Preferably, the dynamic control mechanism is configured as follows: The material loosening state is determined based on the force value F detected by the mechanical sensor; When F>F max When the time is right, it is determined to be a fully stacked state; When F min <F ≤ F max At that time, it was determined to be a state of moderate accumulation; When F ≤ F min When this occurs, it is determined to be in a combing state; Among them, F max F is the preset maximum force threshold. min This is the preset minimum force threshold.

[0018] Preferably, the dynamic control mechanism is further configured as follows: In the initial state, the feeding mechanism is controlled to open, and the lifting mechanism is controlled to drive the combing and scraping mechanism to rise at a first speed V1. When the material is determined to be in a fully stacked state, the feeding mechanism is shut down, and the lifting mechanism is raised at a second speed V2. <V1; When the material is determined to be in a moderate accumulation state, the feeding mechanism is shut down, and the lifting mechanism is raised at a third speed V3, where V2 ≤ V3. <V1; When the material combing state is determined, the feeding mechanism is activated, and the lifting mechanism is accelerated to the first speed V1.

[0019] Preferably, it also includes a vision sensor for acquiring material images, the vision sensor being disposed above the scraper; The dynamic control mechanism is also used to analyze the material image. When it detects that the material has an off-color or clumps, it outputs a stop signal to control the feeding mechanism and the lifting mechanism to stop operating.

[0020] A method for efficient homogenization of loosely packed tissues in large embryos based on dynamic control technology includes the following steps: The sensing mechanism is integrated into the combing and scraping mechanism, and the combing and scraping mechanism and the sensing mechanism are set together inside the press grinding wheel ring; in the initial state, the feeding mechanism is started to feed materials, and at the same time the grinding wheel rotation mechanism is started to drive the press grinding wheel ring to rotate, and the combing and scraping mechanism rises at the first speed. The sensing mechanism detects the force between the material and the carding mechanism, and determines the loose state of the material based on the detected force value and performs dynamic control, specifically including: When the detected force value exceeds the preset maximum force threshold, it is determined to be in a state of complete accumulation. At this time, the mold rotation mechanism is kept running, the feeding mechanism is paused, and the rising speed of the combing and scraping mechanism is adjusted to a second speed that is less than the first speed. When the detected force value is between the preset minimum force threshold and the maximum force threshold, it is determined to be a moderate accumulation state. At this time, the grinding wheel rotation mechanism is kept running, the feeding mechanism is paused, and the rising speed of the combing and scraping mechanism is adjusted to a third speed that is greater than the second speed and less than the first speed. When the detected force value is lower than the preset minimum force threshold, it is determined to be in combing state. At this time, the mold rotation mechanism is kept running, the feeding mechanism is started, and the rising speed of the combing mechanism is restored to the first speed. After the feeding process is completed, the combing and scraping mechanism is turned off.

[0021] This invention achieves the combing and scraping process of large grinding wheel forming by adjusting the speed of the lifting mechanism in real time through a dynamic control mechanism, and then adjusting the combing and scraping mechanism in real time through a combing and scraping mechanism. It can effectively identify the state of loose blanks and improve the uniformity of the loose material structure in real time. Attached Figure Description

Detailed Implementation

[0024] like Figure 1 As shown in Figure -3, this invention provides a highly efficient homogenization device for large embryonic loose tissue based on dynamic control technology, comprising: The material combing and scraping mechanism includes a scraper 201 and a material combing fork 202 located at one end of the scraper 201, which is used to perform lifting and lowering actions within the grinding ring 1 of the press wheel to comb and loosen the material. The sensing mechanism 3 is installed on the combing and scraping mechanism and is used to detect the loose state of the material; The lifting mechanism, connected to the combing and scraping mechanism, is used to drive the combing and scraping mechanism to perform lifting and lowering movements; The dynamic control mechanism is electrically connected to the sensing mechanism 3 and the lifting mechanism respectively, and is used to control the operation of the lifting mechanism according to the material loosening status detected by the sensing mechanism 3.

[0025] The feeding mechanism 5 is used to feed materials into the grinding ring 1 of the press grinding wheel; the dynamic control mechanism is further electrically connected to the feeding mechanism 5 and is used to control the start and stop of the feeding mechanism 5 according to the material loading status.

[0026] The grinding wheel rotation mechanism is used to drive the grinding wheel grinding ring 1 of the press to rotate. In this embodiment, the grinding wheel rotation mechanism is a component of the press forming equipment, and will not be described in detail here. During grinding wheel production, the grinding wheel rotation mechanism remains rotating.

[0027] The combing and scraping mechanism also includes a swing arm mechanism. The end of the scraper 201 away from the combing fork 202 is connected to the swing arm mechanism, and the bottom of the swing arm mechanism is connected to the lifting mechanism.

[0028] The swing arm mechanism includes a lower arm 203 and a horizontal swing arm 204. The lower end of the lower arm 203 is connected to the scraper 201, and the upper end is connected to one end of the horizontal swing arm 204. The other end of the horizontal swing arm 204 is connected to the vertical lifting rod 401. The length and swing angle of the horizontal swing arm 204 can be adjusted according to the diameter of the mold. It occupies little space and can be effectively integrated into semi-automatic or traditional press forming equipment to meet the production needs of various large thick grinding wheels.

[0029] To facilitate scraping, the angle between the scraper 201 and the radial line of the press grinding wheel 1 is 5° to 30°. Three to 15 comb forks 202 can be provided, with fork head diameters ranging from 3mm to 5mm, fork head spacing from 5mm to 50mm, and fork head lengths from 30mm to 80mm. The scraper 201 has a length of 50mm to 180mm, a height of 50mm to 100mm, and a thickness of 2mm to 20mm.

[0030] The sensing mechanism 3 employs a force sensor, which is mounted on the scraper 201 of the combing mechanism to detect the pressure of the material on the scraper 201. In this embodiment, multiple force sensors are provided, all mounted on the scraper 201, to detect the force between the material and the combing mechanism in real time. The multiple force sensors are evenly distributed on one side of the scraper 201, and to improve the stability of the force sensors, they are all mounted on the support plate 205.

[0031] like Figure 4 and Figure 5 As shown, for easy viewing, Figure 5 The drive unit is placed in reverse. The lifting mechanism includes a vertical lifting rod 401 and a drive unit. The drive unit is used to drive the vertical lifting rod to move up and down. The drive unit is an electric push rod. In this embodiment, the drive unit includes a servo motor 402 and a reduction mechanism 403 connected to the servo motor 402. The output end of the reduction mechanism 403 is connected to a lead screw 404. A lead screw sleeve is fixed to the lower end of the vertical lifting rod 401, and the lead screw sleeve is threaded to the upper part of the lead screw. The lifting mechanism also includes a guide sleeve 405, which is sleeved on the vertical lifting rod. The reduction mechanism 403 includes multiple meshing gears. The bottom end of the lifting mechanism is fixedly connected to the fixed seat 6. The initial height of the combing and scraping mechanism is adjusted according to the mold height by the lifting mechanism. During the production process, the speed is changed in real time under the control of the dynamic control mechanism.

[0032] The servo motor 402 receives a control signal and begins to rotate. The rotational power of the servo motor 402 is transmitted to the reduction mechanism 403, which drives the lead screw 404 to rotate. The rotating lead screw 404 drives the lead screw sleeve on it. Due to the restriction of the guide sleeve, the lead screw sleeve cannot rotate, and can only drive the vertical lifting rod 401 to perform linear lifting motion. By controlling the rotation angle and number of revolutions of the servo motor, the stroke and final position of the lifting rod can be precisely controlled.

[0033] The dynamic control mechanism is configured as follows: The material loosening state is determined based on the force value F detected by the force sensor; When F>F max When the time is right, it is determined to be a fully stacked state; When F minWhen F ≤ F max it is determined as a medium accumulation state; When F ≤ F min it is determined as a material combing state; where F max is a preset maximum force threshold, and F min is a preset minimum force threshold.

[0034] The maximum force threshold F max has a value range of (1.5, 2.5] N, and the minimum force threshold F min has a value range of [1, 1.5] N. In this embodiment, F max takes 2.5 N, and F min takes 1.5 N.

[0035] The dynamic regulation mechanism is further configured to: In the initial state, control the feeding mechanism 5 to start, and control the lifting mechanism to drive the combing and scraping mechanism to rise at a first speed V1, where the first speed V1 ranges from 3 mm / s to 10 mm / s; When it is determined as a complete accumulation state, control the feeding mechanism 5 to close, and control the lifting mechanism to rise at a second speed V2, where V2 < V1; in this embodiment, the second speed V2 is 30% to 50% of the first speed V1.

[0036] When it is determined as a medium accumulation state, control the feeding mechanism 5 to close, and control the lifting mechanism to rise at a third speed V3, where V2 ≤ V3 < V1; in this embodiment, the third speed V3 is 50% of the first speed V1.

[0037] When it is determined as a material combing state, control the feeding mechanism 5 to start, and control the lifting mechanism to accelerate to the first speed V1.

[0038] By controlling the rising speed of the combing and scraping mechanism, the amount of material combed in the grinding wheel ring of the press is controlled. To ensure the consistency of abrasive feeding and combing, in the material combing state, when the grinding tool rotating mechanism rotates one circle, the amount of material fed by the feeding mechanism is the same as the amount of material combed by the combing and scraping mechanism.

[0039] The dynamic regulation mechanism is further configured to: When the feeding reaches the set feeding time, control the feeding mechanism 5 to close, and control the lifting mechanism to rise at a fourth speed V4 less than V1 to continue combing and scraping the remaining material. In this embodiment, the fourth speed V4 is 30% to 50% of the first speed V1, When F ≤ F0, control the lifting mechanism to rise at a fifth speed V5 less than V4, and when F ≤ F1, control the lifting mechanism to stop, and the combing and scraping mechanism to hover to further comb and scrape the remaining material.

[0040] In this embodiment, the fifth speed V5 is 10% of the first speed V1. Among them, F0 is the first critical force threshold, and F0 < F min , in this embodiment, F0 is taken as 0.5 N.

[0041] After the feeding is completed, by raising the scraping mechanism to a certain height and then hovering it, while decelerating, to avoid the scraping material being too high or too low from the material and unable to scrape the material.

[0042] After waiting until the set time, in this embodiment, the set time is from 10 s to 30 s, control the lifting mechanism to drive the scraping mechanism to hover at the set position, and the scraping is completed. Among them, F1 is the second critical force threshold, and F1 < F0; in this embodiment, F1 is taken as 0.05 N.

[0043] It further includes a vision sensor for collecting material images, and the vision sensor is arranged above the scraper; the dynamic regulation mechanism is also used to analyze the material images. When it identifies that there are different colors or lumps in the material, it outputs a shutdown signal to control the feeding mechanism 5 and the lifting mechanism to stop running.

[0044] It further includes an alarm mechanism; the dynamic regulation mechanism is also configured to: when it detects that the feeding speed of the feeding mechanism 5 exceeds the set threshold, or detects that the material accumulation height exceeds the height of the scraper 201, it outputs an alarm signal to the alarm mechanism to trigger an alarm.

[0045] The present invention detects the force between the material and the scraping mechanism through the induction mechanism 3, judges the loose packing state of the material according to the detected force value and conducts dynamic regulation: As Figure 3 shown in the dynamic regulation curve, when the force value exceeds the maximum force threshold, it indicates that the material accumulation is too much and it is in a completely accumulated state, and it is necessary to scrape the material as soon as possible. The change of the force value is as Figure 3 shown in stage A in, at this time, stop feeding and reduce the rising speed of the scraping mechanism. At the same time, the grinding tool rotating mechanism keeps running, and the material is scraped by the scraping mechanism during the rotation process. By reducing the rising speed of the scraping mechanism, the amount of material scraped per unit time is increased, and the accumulated material can be quickly scraped; When the force value is between the maximum force threshold and the minimum force threshold, it indicates that the material accumulation has decreased to a certain extent and it is in a moderately accumulated state. The change of the force value is as Figure 3 shown in stage B in, at this time, stop feeding and increase the rising speed of the scraping mechanism. At the same time, the grinding tool rotating mechanism keeps running, and the material is continuously scraped by the scraping mechanism during the rotation process, but the amount of material scraped per unit time is reduced compared with the completely accumulated state; When the force value is less than the minimum force threshold, it indicates that the material is no longer accumulating and it is in a scraping state. The change of the force value is as Figure 3 shown in stage C in, at this time, continue feeding, and the scraping mechanism rises at the first speed to restore the initial state.

[0046] This invention achieves the combing and scraping process of large grinding wheel forming by adjusting the speed of the lifting mechanism in real time through a dynamic control mechanism, and then adjusting the combing and scraping mechanism in real time through a combing and scraping mechanism. It can effectively identify the state of loose blanks and improve the uniformity of the loose material structure in real time.

[0047] This invention also provides a method for efficient homogenization of loosely packed tissue in large embryos based on dynamic control technology, comprising the following steps: The sensing mechanism is integrated into the combing and scraping mechanism, and the combing and scraping mechanism and the sensing mechanism are set together inside the press grinding wheel ring; in the initial state, the feeding mechanism is started to feed materials, and at the same time the grinding wheel rotation mechanism is started to drive the press grinding wheel ring to rotate, and the combing and scraping mechanism rises at the first speed. The interaction force between the material and the carding mechanism is detected by a sensing mechanism. Based on the detected force value, the loose packing state of the material is determined and dynamic control is performed. Specifically, this includes: When the detected force value exceeds the preset maximum force threshold, it is determined to be in a state of complete accumulation. At this time, the mold rotation mechanism is kept running, the feeding mechanism is paused, and the rising speed of the combing and scraping mechanism is adjusted to a second speed that is less than the first speed. When the detected force value is between the preset minimum force threshold and the maximum force threshold, it is determined to be a moderate accumulation state. At this time, the grinding wheel rotation mechanism is kept running, the feeding mechanism is paused, and the rising speed of the combing and scraping mechanism is adjusted to a third speed that is greater than the second speed and less than the first speed. When the detected force value is lower than the preset minimum force threshold, it is determined to be in combing state. At this time, the mold rotation mechanism is kept running, the feeding mechanism is started, and the rising speed of the combing mechanism is restored to the first speed. After the feeding process is completed, the combing and scraping mechanism is turned off.

[0048] The method of the present invention is used to realize the above-mentioned efficient homogenization device for large embryo loose tissue based on dynamic control technology, which will not be described in detail here.
