Description

Technical Field

[0001] This utility model relates to the field of grinding wheel pressing technology, and in particular to a grinding wheel pressing structure that facilitates the extraction of the grinding wheel. Background Technology

[0002] A grinding wheel is a porous bonded abrasive tool made of abrasive and binder through processes such as pressing and sintering. It is mainly used for grinding, polishing, and cutting metal and non-metal materials. It is a commonly used tool in machining and manufacturing. The abrasive particles distributed on the surface of the high-speed rotating grinding wheel cut, scrape or grind the surface of the workpiece by means of the sharp edges of the particles to remove excess material from the workpiece, so as to achieve the purpose of trimming dimensions, improving surface roughness or processing specific shapes.

[0003] Referring to prior art document 201720459912.4, a grinding wheel pressing mold structure for easy extraction of grinding wheels is provided. By setting a V-shaped bar in the empty groove area and a T-shaped bar at the other end of the V-shaped bar, pressing the T-shaped bar downwards with a hand causes the other end of the V-shaped bar to move upwards, thereby prying the movable block. After the grinding wheel tilts, it can be easily removed by hand.

[0004] The device provided in the aforementioned comparative document has difficulty controlling the force used when prying the grinding wheel, which may damage the grinding wheel. Damaged grinding wheels cannot meet the usage standards and are directly scrapped, resulting in waste of raw materials and increased production costs. At the same time, after tilting the grinding wheel, it is still necessary to manually remove the grinding wheel, which increases the labor intensity of workers, slows down the production pace, and results in a lot of lost time during mass production. Utility Model Content

[0005] The purpose of this invention is to solve the problem of easy damage to grinding wheels during the extraction process in the prior art, and to propose a grinding wheel pressing mold structure that facilitates the extraction of grinding wheels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A grinding wheel pressing mold structure for easy extraction of grinding wheels includes a base and a lower mold base for placing the grinding wheel. The lower mold base is provided with a feeding mechanism for abutting and separating the grinding wheel, and the base is provided with a flipping mechanism for driving the lower mold base to flip. The feeding mechanism includes a telescopic rod fixedly installed in the lower mold base, and a mounting platform is fixedly connected to the output end of the telescopic rod. Four symmetrically arranged pressure rods are fixedly installed on the mounting platform, and a contact plate for abutting the grinding wheel is fixedly installed at the end of the pressure rod. The lower mold base has four circumferentially distributed limiting grooves that cooperate with the contact plates. The contact plates and pressure rods extend to the upper end of the lower mold base. A material collection frame for collecting the grinding wheel is provided on the side of the base. The flipping mechanism includes a support frame fixedly installed on a base, and a flipping shaft is movably installed inside the support frame. The lower mold base is located on the flipping shaft. A sliding groove is provided on the base, and a moving block is slidably sleeved in the sliding groove. A cylinder connected to the moving block is fixedly installed in the sliding groove. A traction plate is integrally connected to the upper end of the moving block, and a pin end that cooperates with the flipping shaft is fixedly connected to the upper end of the traction plate.

[0007] Preferably, the mounting platform is a circular structure and is horizontally arranged, the pressure rod is vertically arranged, the material collection frame is horizontally arranged below the lower mold base, and the material collection frame is an open frame structure.

[0008] Preferably, the support frame has a guide hole for guiding the flipping shaft, and the guide hole is opened at an angle. A horizontally arranged bracket is fixedly installed on the support frame, and a support block for supporting the lower mold base is fixedly installed on the bracket.

[0009] Preferably, the support frame is vertically arranged on both sides of the base, the traction plate is vertically arranged on the moving block, the bracket and the traction plate are fixedly installed with movable limiting ends, the two support blocks are symmetrically arranged on the bracket, and a baffle for limiting the moving block is fixedly installed at the upper end of the base, and a pressure sensor is fixedly installed on the baffle.

[0010] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses an abutment plate to push the grinding wheel out of the limiting groove, and uses a uniform upward thrust to break the adhesion between the grinding wheel and the lower mold base in advance. This avoids excessive local stress on the grinding wheel caused by single-point pushing, effectively preventing cracks and chipping of the grinding wheel due to stress imbalance, significantly reducing the damage rate of the product during unloading, ensuring smoother subsequent flipping and unloading, and indirectly improving the extraction rate.

[0011] 2. This utility model uses a traction plate to drive the flipping shaft to flip along the limiting hole, so that the lower mold base changes from a horizontal state to an inclined state. Under the action of gravity, the grinding wheel quickly detaches from the lower mold base and falls into the lower collection frame. At the same time, the setting of the limiting end and the baffle limits the flipping angle of the lower mold base to avoid the flipping angle being too large. This automated flipping unloading reduces manual operation and greatly improves production efficiency. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-5 A grinding wheel pressing mold structure for easy extraction of grinding wheels includes a base 1 and a lower mold base 2 for placing the grinding wheel. To further explain, a controller that is electrically connected to a cylinder 41, a telescopic rod 51, and a pressure sensor is fixedly installed on the base 1, and an installation cavity is provided in the lower mold base 2.

[0016] The lower die holder 2 is equipped with a feeding mechanism 5 for separating the grinding wheel by contact, and the base 1 is equipped with a flipping mechanism 4 for driving the lower die holder 2 to flip.

[0017] The feeding mechanism 5 includes a telescopic rod 51 fixedly installed in the lower mold base 2, and a mounting platform 52 is fixedly connected to the output end of the telescopic rod 51. Four symmetrically arranged pressure rods 53 are fixedly installed on the mounting platform 52, and a contact plate 54 for contacting the grinding wheel is fixedly installed at the end of the pressure rod 53. The telescopic rod 51, the mounting platform 52, and the pressure rods 53 are all fixedly installed in the mounting cavity at the bottom of the lower mold base 2.

[0018] The telescopic rod 51 serves as the power source, typically employing either a pneumatic telescopic rod or an electric push rod, selected based on the weight of the grinding wheel. Heavy grinding wheels are best suited for pneumatic models with a thrust of 500N or more.

[0019] The mounting platform 52 is coaxial with the telescopic rod 51, which converts the single-point thrust of the telescopic rod 51 into a uniform distribution of the force to the four test cylinders, thus avoiding uneven load distribution.

[0020] The end contact plate 54 is adapted to the curvature of the grinding wheel edge and the surface is treated with anti-slip treatment. When the telescopic rod 51 extends, the pressure rod 53 drives the contact plate 54 to extend out of the limiting groove 8 of the lower mold base 2 and directly contact the bottom surface of the grinding wheel. The upward thrust causes the grinding wheel to separate from the surface of the lower mold base.

[0021] The lower mold base 2 has four circumferentially distributed limiting grooves 8 that cooperate with the abutment plate 54. The design of the limiting grooves 8 provides vertical movement guidance for the abutment plate 54, avoids the abutment plate 54 from lateral swaying, and ensures that the grinding wheel is under stable force during the push.

[0022] The size of the limiting groove 8 is slightly larger than the size of the contact plate 54, so that the contact plate 54 can be retracted into the mounting cavity when it is not necessary to separate the grinding wheel from the contact plate.

[0023] The contact plate 54 and the pressure rod 53 extend to the upper end of the lower mold base 2, and the base 1 is provided with a material collection frame 3 for collecting the grinding wheel on the side.

[0024] The mounting platform 52 has a circular structure and is set horizontally, while the pressure rod 53 is set vertically to ensure that the contact plate 54 is in parallel contact with the bottom surface of the grinding wheel when pushing, so as to avoid excessive local force that could cause the edge of the grinding wheel to crack.

[0025] The material collection frame 3 is horizontally positioned below the lower mold base 2, and the material collection frame 3 is an open frame structure, which not only provides space for the lower mold base 2 to flip over, but also reduces the impact when the grinding wheel falls.

[0026] The flipping mechanism 4 includes a support frame 44 fixedly installed on the base 1, and a flipping shaft 46 is movably installed inside the support frame 4. The support frame 44 is used to support the flipping shaft 46, and the spacing of the support frame 44 matches the width of the lower mold base 2 to ensure no interference during flipping.

[0027] The flipping shaft 46 is the "rotation center" of the lower mold base and slides and rotates along the channel.

[0028] The lower mold base 2 is mounted on the flipping shaft 46. The base 1 has a sliding groove 47, and a moving block 42 is slidably fitted inside the sliding groove 47. A cylinder 41 connected to the moving block 42 is fixedly installed inside the sliding groove 47. The output end of the cylinder 41 is rigidly connected to the moving block 42. The moving block 42 and the sliding groove 47 are clearance-fitted to ensure smooth linear sliding.

[0029] The upper end of the moving block 42 is integrally connected to the traction plate 43, and the upper end of the traction plate 43 is fixedly connected to a pin end that cooperates with the flipping shaft 46.

[0030] The pin end at the top of the traction plate 43 is inserted into the radial hole of the flipping shaft 46, converting linear motion into rotational motion.

[0031] When the cylinder 41 extends or retracts, the moving block 42 drives the traction plate 43 to push and pull the flipping shaft 46, causing the flipping shaft 46 to move along the guide hole 45 and drive the lower mold base 2 to flip.

[0032] The support frame 44 is provided with a guide hole 45 for guiding the flip shaft 46. The guide hole 45 is opened at an angle, and the length of the angled guide hole 45 is adapted to the movement stroke of the flip shaft 46. The angled design allows the flip shaft to complete the compound movement of "sliding outward" and "rotating upward" at the same time when it is pulled, so as to drive the lower mold base 2 to smoothly change from a horizontal state to an angled state.

[0033] A horizontally set bracket is fixedly installed on the support frame 44. A support block 6 for supporting the lower mold base 2 is fixedly installed on the bracket. The bracket is a horizontal steel plate. The support block 6 is used to lift the lower mold base 2 in the non-flipped state to ensure the horizontality of the lower mold base 2 and ensure the accuracy of grinding wheel pressing.

[0034] The support frame 44 is vertically set on both sides of the base 1, and the traction plate 43 is vertically set on the moving block 42. The support frame and the traction plate 43 are fixedly installed with movable abutting limit ends 7. The limit ends 7 are fixed on the support frame and the traction plate 43 respectively. When the flipping shaft 46 moves to the limit position, the two limit ends 7 abut against each other, mechanically limiting the flipping angle and preventing the lower mold base 2 from over-flipping and causing the grinding wheel to hit the collection frame 3.

[0035] Two support blocks 6 are symmetrically arranged on the bracket. A baffle 48 for limiting the movement of the moving block 42 is fixedly installed at the upper end of the base 1. A pressure sensor is fixedly installed on the baffle 48. The baffle 48 is vertically fixed to the end of the slide groove 47. When the cylinder 41 drives the moving block 42 to the end of its stroke, the moving block 42 contacts the baffle 48. The pressure sensor detects the pressure signal and feeds it back to the controller, which determines that the flipping is in place and triggers the subsequent reset action, thereby improving the reliability of automation.

[0036] The functional principle of this utility model can be explained through the following operation methods: After forming by grinding wheel pressing mold; The controller sends a start signal to the telescopic rod 51, and the output end of the telescopic rod 51 begins to extend upward, pushing the mounting platform 52, the pressure rod 53, and the contact plate 54 to rise synchronously. The contact plate 54 extends out of the limiting groove 8. When the contact plate 54 contacts the bottom surface of the grinding wheel and applies upward pressure, it separates the grinding wheel from the lower die holder 2, preparing for subsequent unloading. At this time, the controller sends a signal to the telescopic rod 51, and the output end of the telescopic rod 51 retracts downward, pulling the mounting platform 52, the pressure rod 53 and the contact plate 54 downward back into the limiting groove 8; Then, the controller sends a start signal to the cylinder 41, and the output end of the cylinder 41 begins to extend, driving the moving block 42 and the traction plate 43 to move horizontally to the right synchronously along the slide groove 47. The horizontal rightward thrust of the traction plate 43 pulls the flipping shaft 46 to rotate clockwise along the guide hole 45, and the lower mold base 2 changes from a horizontal state to a vertical state; The grinding wheel on the lower mold base 2 falls into the collection frame 3 due to its own weight, thus completing the collection of the grinding wheel; When the right end of the moving block 42 touches the pressure sensor on the baffle 48 and exceeds the threshold of the pressure sensor, the pressure sensor sends a signal to the controller, the controller sends a signal to the cylinder 41, the output end of the cylinder 41 begins to retract, driving the moving block 42 and the traction plate 43 to move horizontally to the left synchronously along the slide groove 47. The horizontal leftward pull of the traction plate 43 pulls the flipping shaft 46 to rotate counterclockwise along the guide hole 45. After the two limit ends 7 come into contact with each other, the lower mold base 2 falls smoothly onto the support block 6. At this time, the lower mold base 2 changes from a vertical state to a horizontal state, waiting for the next batch of grinding wheels to be loaded.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
