Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grinding wheel processing and forming, in particular to a fine grinding diamond resin grinding wheel and a forming method thereof. BACKGROUND

[0002] The fine grinding diamond resin grinding wheel is a high-performance tool for precision grinding of hard and brittle materials, and its manufacturing usually adopts a hot-press forming process. In order to meet the safety and structural reliability under high-speed rotation, a layer of reinforcing gauze is generally added between the working layer and the non-working layer of the grinding wheel to form a sandwich type interlayer structure. The core role of the gauze is as follows: firstly, it greatly improves the tensile strength and impact toughness of the grinding wheel to prevent it from breaking or delaminating under high-speed centrifugal force; secondly, it optimizes the interface bonding between the working layer and the substrate layer as a stress transfer medium to inhibit crack propagation; and thirdly, it improves the overall stiffness of the grinding wheel to maintain its geometric precision and grinding stability.

[0003] The traditional forming process presents a typical discrete and segmented operation mode, and the specific steps are as follows: firstly, the mixed substrate layer powder is loaded into the mold cavity, and after being scraped and compacted manually or by a simple tool, the operator needs to pause the feeding, lay the annular gauze in the center of the material surface, and at the same time, avoid the gauze from being wrinkled or deviated; after the gauze is laid, the diamond working layer mixture can be continued to be poured, and finally the hot press machine is entered for heating, pressing and solidification.

[0066] A kind of precision grinding diamond resin grinding wheel is processed by a kind of precision grinding diamond resin grinding wheel forming method, and the center of precision grinding diamond resin grinding wheel is provided with gauze 201.

[0067] The working process of the precision grinding diamond resin grinding wheel and the forming method thereof is as follows:

[0068] When machining a single grinding wheel, the process begins with material injection. The mold 100 is moved directly below the fixed cylinder 400, and then activated by cylinder 301. The output of cylinder 301 causes the fixed cylinder 400 to move downwards, bringing the bottom of the rotating cylinder 600 close to the inner bottom of the mold 100. Then, the first motor 302 is activated. The rotation of the first motor 302 drives the gear ring 607 to rotate via gear 303 and the transmission gear between gear 303 and gear ring 607, thereby causing the rotating cylinder 600 to rotate as a whole. In the initial state, the ball bearing 60... Position 6 is located at the lowest point of the first lifting groove 401. When the rotating cylinder 600 rotates, the ball bearing shaft 606, in conjunction with the first lifting groove 401, drives the rotating cylinder 600 to slowly rise along the first lifting groove 401 while rotating. During the rising process of the rotating cylinder 600, the toothed groove 608 engages with the threaded tube 707, simultaneously lifting the threaded tube 707 and the threaded sleeve 702. At the same time, the meshing transmission between the gear at the top of the threaded tube 707 and the toothed groove 608, combined with the threaded transmission between the threaded tube 707 and the threaded sleeve 702 during rotation, drives the threaded tube 707... The threaded sleeve 702 is further lifted. When the threaded sleeve 702 and the linkage ring 701 are lifted, they drive the support plate 706 to lift, raising the material inside the storage cavity 704 to above the edge of the storage cavity 704. When the drive shaft of the first motor 302 drives the blade 703 to rotate, the blade 703 gathers the lifted material and pushes it to the adjacent discharge port 705 for discharge into the mold 100, realizing automatic material discharge. The volumetric metering discharge method is adopted, which, compared with the traditional gravity discharge method, not only has higher accuracy and more uniform discharge, but also avoids clogging and material agglomeration, thus improving the molding process. The uniformity and quality of the pre-filling material are ensured. At the same time, during the material discharge process, the rotating cylinder 600 rotates, and the detection roller 613 at the bottom of the rotating cylinder 600 rotates synchronously to achieve automatic leveling of the filling area, ensuring the uniformity and flatness of the bottom filling. Compared with the traditional top-filling powder that relies on its own weight to accumulate, its loose density is low and fluctuates greatly, and there are a large number of pores and arching effects inside. During subsequent pressing, it has large shrinkage, difficult air degassing, and difficult density gradient control. Through synchronous leveling, in-situ pre-compaction and controllable loose density can be achieved, effectively improving the quality of grinding wheel forming injection processing.

[0069] Further, as the rotating cylinder 600 gradually rises, when the material is injected to the middle position of the mold 100, at this time the ball shaft 606 rises from the first lifting groove 401 to the inside of the rotating groove 403, and keeps rotating in the horizontal direction inside the rotating groove 403, at the same time, the detection roller 613 also rises to contact and press the micro switch 616 located directly above the detection roller 613, so as to make the detection switch 614 energized and start, enter the detection mode, at this time the rotating cylinder 600 reciprocates in the horizontal direction, since the position of the rotating cylinder 600 is no longer lifted, the injection will not continue, at this time the detection roller 613 is used to smooth the material injection area and detect the flatness, at this time when the detection roller 613 passes through the material area, the pressure between the detection roller 613 and the material is detected, the higher the material in the detection area, the greater the force of the detection roller 613, and vice versa, when the detection roller 613 passes through, the force of the material acting on the detection roller 613 will make the detection roller 613 move in the vertical direction synchronously with the detection cylinder 612, when the detection cylinder 612 moves, the pressure in the sealing groove 609 changes, which drives the piston ring 615 to move in the vertical direction by a larger distance, so as to amplify the displacement detection result, when the piston ring 615 moves, the conductive contact piece 611 moves synchronously in the vertical direction, and the conductive contact pieces 611 corresponding to each group of detection rollers 613 are close to each other except the conductive contact pieces 611 connected to both ends of the detection switch 614, when the material surface pressure detected by each group of detection rollers 613 is consistent, the distance moved by each group of detection rollers 613 also tends to be consistent, so as to make the moving distance of each group of piston rings 615 and conductive contact pieces 611 close to each other, until each group of adjacent conductive contact pieces 611 are close to contact and form a complete loop, otherwise the rotating cylinder 600 continues to rotate to smooth the material surface, until the flatness of the area detected by each group of detection rollers 613 is consistent.

[0070] When the detection switch 614 forms a complete circuit through the contact communication of the conductive contact pieces 611, the detection switch 614 is controlled to start the second motor 601 through the electrical connection, the output end of the second motor 601 drives the gear two 603 to rotate, further drives the gear three 604 to rotate, and simultaneously drives the gear three 604 and the rotating rod 602 to rotate synchronously through the meshing transmission of the gear three 604 and the gear four 605, so that the rotating rod 602 drives the detection cylinder 612 and the detection roller 613 to rotate until the detection roller 613 rotates to a position where it cannot block the screen 201 at the bottom of the rotating cylinder 600. Since the bottom of the lifting cylinder 500 is close to the bottom of the rotating cylinder 600 at this time, when the detection roller 613 rotates, the transmission block 506 is driven to rotate along the central rotating shaft when passing through the transmission block 506. Since one side is away from the lifting cylinder 500, the magnetic force decreases, and the other side is close to the bottom of the lifting cylinder 500, the magnetic force increases, which causes the transmission block 506 to rotate 90°. Not only does it release the clamping of the screen 201, but also it realizes the automatic release of the flat material surface screen 201 after detection, and through the rotation of the transmission block 506, the blocking of the exhaust passage 505 is released. The compressed gas in the compression chamber 502 can be discharged from the exhaust passage 505 to the direction of the screen 201 through the reset of the piston block 503. Due to the porous structure of the screen 201 and the micro gap between the screen 201 and the lower layer of the base material, the environment air, the air entrained by the powder and the low molecular volatile components in the resin can be captured. In the subsequent hot pressing process, these gases expand due to heating. If they cannot be discharged in time through the exhaust passage, they will be wrapped by the molten resin, forming interface bubbles or delamination defects. By blowing the surface of the screen 201 before the powder is covered, active gas replacement is achieved, replacing and reducing the humid air and low molecular volatiles trapped at the interface between the screen 201 and the powder. Moreover, a distributed micro-compression force can be generated by the soft downward airflow, which helps to tightly adhere the screen 201 to the lower layer of the base material, achieving better initial adhesion and reducing the possibility of micro-suspension or fluctuation of the screen 201 due to static electricity or its own stiffness. If the subsequent powder directly impacts in free fall, it will cause the screen 201 to be partially embedded or wrinkled, which will destroy the continuity and uniform stress distribution of the screen 201 as a reinforcing layer.

[0071] With the gradual discharge of the airflow inside the compression cavity 502, the pressure inside the compression cavity 502 becomes low, at the same time, the gas inside the piston cylinder 405 is discharged to the compression cavity 502 through the gas-tight tube 404 under the action of the spring elastic force between the piston rod 406 and the piston cylinder 405 until the discharge, so that the piston rod 406 moves down, drives the fork 407 to rotate downward, when the subsequent ball shaft 606 passes, the side of the fork 407 moves to the inside of the second lifting groove 402, and the ball shaft 606 and the second lifting groove 402 are matched to realize continuous rotation and rise, so as to complete the filling of the rear half of the material. Since the construction of the bottom powder foundation and the automatic arrangement of the gauze 201 have been completed, the rear half of the filling material only needs to be evenly discharged through the blade 703, and finally the product can be obtained through hot pressing.

[0072] It should be noted that when the device is filled, the second motor 601 is first reversed to rotate, and the detection roller 613 is restored to its original position. When the detection roller 613 passes through the transmission block 506, the transmission block 506 can be driven to rotate 90°, so that it restores the blockage of the exhaust passage 505. At the same time, new gauze 201 can be filled. During the resetting process of the rotating cylinder 600, through the inverted T-shaped limiting structure on the inner wall of the rotating cylinder 600, during the downward movement of the rotating cylinder 600, through the limiting structure at the top, the lifting cylinder 500 is driven to move down, the gas between the fixed cylinder 400 and the lifting cylinder 500 is compressed into the piston cylinder 405 and the compression cavity 502 through the gas-tight tube 404 and the communication tube 501 respectively, and is discharged when the exhaust passage 505 is unblocked in the next working cycle. When the lifting cylinder 500 moves up during the working process, the gas can be sucked in through the one-way air inlet valve at the top of the lifting cylinder 500, which is convenient for subsequent compression cycle work discharge.

For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
