Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of grinding wheel production, and more specifically, to a pressing device for grinding wheel production. Background Technology

[0002] In the grinding wheel production process, the pressing process is a crucial step to ensure uniform grinding wheel density and stable performance. Traditional grinding wheel pressing devices mostly use a longitudinal pressing method, which has significant technical bottlenecks and severely restricts the improvement of production efficiency and product quality.

[0003] Existing longitudinal pressing devices typically press only a single grinding wheel blank at a time, operating on a single pressing and forming basis, requiring repeated operations to complete mass production. This "one-to-one" pressing mode significantly extends the production cycle, failing to meet the growing market demand, especially during large-scale order production, where insufficient capacity becomes particularly prominent. Furthermore, the longitudinal pressing device has a complex demolding and separation design. After the blank is pressed, multiple steps are required to release the pressing pressure and separate the mold from the blank, involving cumbersome mechanical operations and parameter adjustments. This not only consumes a significant amount of time but also easily leads to grinding wheel blank breakage due to improper operation, resulting in raw material waste and increased production costs.

[0004] Furthermore, uneven pressure distribution during longitudinal pressing easily leads to density differences within the grinding wheel blank, affecting key performance indicators such as strength and wear resistance of the finished grinding wheel, thus reducing the product qualification rate. This technical limitation not only restricts the production scale and economic benefits of grinding wheel manufacturers but also makes it difficult to meet the requirements of modern manufacturing for efficient and high-precision production equipment. Therefore, there is an urgent need to develop a new type of pressing device for grinding wheel production to solve the problems of low single-press quantity and cumbersome demolding and separation in traditional longitudinal pressing methods, in order to achieve efficient, stable, and batch grinding wheel production. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a pressing device for grinding wheel production, which solves the problem that the traditional grinding wheel production pressing devices in the prior art mostly adopt a longitudinal pressing method, which has significant technical bottlenecks and seriously restricts the improvement of production efficiency and product quality.

[0006] According to one aspect, at least one embodiment of this disclosure provides a pressing device for grinding wheel production, comprising:

[0007] The equipment frame, the hydraulic press, and a pair of pressure heads are provided. The hydraulic press is located on the top of the equipment frame, and the pressure heads are located at the bottom of the output end of the hydraulic press.

[0008] A feeding and propulsion assembly is disposed in the equipment frame;

[0009] The equipment includes a base frame and a discharge separation assembly, wherein the base frame is disposed at the bottom of the equipment frame and the discharge separation assembly is disposed on the equipment frame and the base frame;

[0010] The feeding and propulsion assembly includes several rolling rods, all of which are rotatably connected within the equipment frame. A first cylinder is provided on one side of the equipment frame, and the direction of the first cylinder is parallel to that of the rolling rods.

[0011] As a further technical solution, a second cylinder is provided on one side of the equipment frame, and a push plate is provided at the output end of the second cylinder and the output end of the first cylinder. The first cylinder is located at the central axis of the hydraulic press.

[0012] As a further technical solution, the discharge separation assembly includes a pair of conveyor rollers, both of which are rotatably connected within the base frame. A pair of conveyor belts are fitted between the conveyor rollers, and an outer frame is provided on one side of the equipment frame.

[0013] As a further technical solution, an empty mold discharge rack is provided at one end of the outer frame, the empty mold discharge rack corresponds to the position of the conveyor belt on one side, a drive motor is provided on the outer surface of the outer frame, and a rotating frame is provided at the output end of the drive motor.

[0014] As a further technical solution, a flipping separation frame is provided at one end of the rotating frame, and a third cylinder is fixedly connected to the side surface of the rotating frame and the side surface of the equipment frame. Openings are provided on both sides of the flipping separation frame, and clamping blocks are provided at the output end of the third cylinder. The flipping separation frame is located directly above the other conveyor belt.

[0015] As a further technical solution, the inner surface of the equipment frame located at the rolling rod is an inclined structural surface, and the rolling rods are arranged sequentially from high to low.

[0016] As a further technical solution, baffles are provided on both sides of the empty mold discharge rack, and the bottom of the empty mold discharge rack has an inclined structure.

[0017] As a further technical solution, the inner width dimension of the equipment frame is matched with the size of the grinding wheel mold.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the feeding and propulsion assembly achieves efficient feeding through the cooperation of rolling rods and dual cylinders. The rolling rods are designed to be arranged at an angle from high to low, allowing the mold to slide quickly into the equipment frame with the help of gravity, reducing feeding resistance and improving feeding smoothness. The first cylinder and the second cylinder work together. First, the first cylinder assists in pushing the mold, and then the second cylinder precisely positions it to ensure that the mold is accurately pushed to the pressing station below the hydraulic press. This design changes the traditional single feeding method and realizes continuous rolling feeding of materials, providing a stable material supply for the simultaneous operation of the two pressing heads, greatly improving feeding efficiency, thereby shortening the production cycle and meeting the needs of mass production.

[0020] 2. In this disclosure, the discharge separation component achieves automatic separation and directional conveying of the forming grinding wheel and the mold through a combination of mechanical transmission and pneumatic clamping. When the mold enters the flipping separation frame, the third cylinder drives the clamping block to clamp the mold, and the drive motor drives the rotating frame to flip the flipping separation frame. Under the action of gravity, the forming grinding wheel separates from the mold. The grinding wheel falls into the conveyor belt and is transported to the finished product area, while the mold is transported to the recycling area. This component avoids the cumbersome operation of the traditional demolding separation process and does not require manual separation. It not only improves the discharge efficiency but also reduces the damage to the grinding wheel blank caused by improper manual operation, ensuring the integrity of the finished grinding wheel. At the same time, it realizes the recycling and reuse of the mold, reduces raw material waste and production costs, and effectively solves the problem of cumbersome demolding separation in traditional longitudinal pressing devices.

It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-3 As shown, a pressing device for grinding wheel production according to an embodiment of the present disclosure is illustrated, comprising:

[0033] The equipment frame 1, the hydraulic press 2, and a pair of pressure heads 3 are provided. The hydraulic press 2 is located on the top of the equipment frame 1, and the pressure heads 3 are all located at the bottom of the output end of the hydraulic press 2.

[0034] A feeding and propulsion assembly 5 is disposed in the equipment frame 1;

[0035] The base frame 4 and the discharge separation component 6 are provided. The base frame 4 is located at the bottom of the equipment frame 1, and the discharge separation component 6 is located on the equipment frame 1 and the base frame 4.

[0036] The feeding and propulsion assembly 5 includes several rolling rods 5-1, all of which are rotatably connected to the equipment frame 1. A first cylinder 5-2 is provided on one side of the equipment frame 1, and the direction of the first cylinder 5-2 is parallel to that of the rolling rods 5-1. A second cylinder 5-3 is provided on one side of the equipment frame 1. Both the output end of the second cylinder 5-3 and the output end of the first cylinder 5-2 are provided with push plates 5-4. The first cylinder 5-2 is located at the central axis of the hydraulic press 2.

[0037] In some examples, a feeding propulsion assembly 5 is designed to achieve rolling feeding and precise pushing to the pressing position. This assembly is based on a conveying structure using a rolling rod 5-1 rotatably connected within the equipment frame 1. The material can roll freely along the rolling rod 5-1, reducing feeding resistance. The first cylinder 5-2 and the second cylinder 5-3 on one side of the equipment frame 1 work together. When the material rolls to the designated area, the first cylinder 5-2 and the second cylinder 5-3 extend in sequence, and the push plate 5-4 pushes the mold to the pressing station below the hydraulic press 2.

[0038] The first cylinder 5-2 assists in pushing the material, while the second cylinder 5-3 ensures that the mold is precisely positioned directly below the pressure head 3, guaranteeing that the material will not shift or tilt during the pushing process. This design, with two cylinders and a rolling rod 5-1, not only enables continuous rolling feeding of the material but also quickly and stably delivers the material to the pressing position. Compared to the traditional single-feed method, this significantly improves feeding efficiency and provides a stable material supply for the simultaneous operation of both pressure heads 3, meeting the needs of mass production.

[0039] like Figures 1-3 As shown in the figure, the discharge separation component 6 proposed in this embodiment includes a pair of conveyor rollers 6-1, both of which are rotatably connected to the base frame 4. A pair of conveyor belts 6-2 are fitted between the conveyor rollers 6-1. An outer frame 6-3 is provided on one side of the equipment frame 1. A blank mold discharge frame 6-4 is provided at one end of the outer frame 6-3. The blank mold discharge frame 6-4 corresponds to the position of one of the conveyor belts 6-2. A drive motor 6-5 is provided on the outer surface of the outer frame 6-3. A rotating frame 6-6 is provided at the output end of the drive motor 6-5. A flipping separation frame 6-7 is provided at one end of the rotating frame 6-6. A third cylinder 6-8 is fixedly connected to the side surface of the rotating frame 6-6 and the side surface of the equipment frame 1. Both sides of the flipping separation frame 6-7 have openings 6-9. A clamping block 6-10 is provided at the output end of the third cylinder 6-8. The flipping separation frame 6-7 is located directly above the other conveyor belt 6-2.

[0040] In some examples, a discharge separation component 6 is designed to achieve the separation and differentiated conveying of the forming grinding wheel and the mold. This component uses the conveying roller 6-1 and the conveyor belt 6-2 inside the base frame 4 as the conveying carriers to convey the mold and the formed grinding wheel respectively. When the mold is pushed in sequence, it enters the flipping separation frame 6-7. At this time, the third cylinders 6-8 on both sides drive the clamping blocks 6-10 to extend and clamp the two sides of the mold. The drive motor 6-5 on the surface of the outer frame 6-3 drives the rotating frame 6-6 to rotate, and the flipping separation frame 6-7 flips. Using gravity and clamping force, the forming grinding wheel and the mold are separated. The grinding wheel falls into the lower conveyor belt 6-2 and is conveyed to the finished product collection area, while the mold is reset by the clamping block 6-10 with the flipping separation frame 6-7. It is then pushed by the flipping separation frame 6-7 to the empty mold discharge frame 6-4, and falls into the other side conveyor belt 6-2 through the empty mold discharge frame 6-4 and is conveyed to the mold recycling area.

[0041] This component combines mechanical transmission with pneumatic clamping to achieve automatic separation and directional conveying of the forming grinding wheel and the mold, avoiding the tedious operation of manual separation, improving output efficiency, and ensuring the integrity of the finished grinding wheel and the recycling and reuse of the mold.

[0042] For example, such as Figure 1As shown, the inner surface of the equipment frame 1 located at the rolling rod 5-1 is an inclined structural surface, and the rolling rod 5-1 is arranged from high to low.

[0043] In some examples, by varying the height, a slope is formed inside the equipment rack 1, allowing the mold to slide quickly into the equipment rack 1 and be pushed in for molding processing.

[0044] For example, such as Figure 3 As shown, baffles 7 are provided on both sides of the empty mold discharge rack 6-4, and the bottom of the empty mold discharge rack 6-4 is an inclined structure.

[0045] In some examples, baffles 7 are provided to block the sides of the empty mold discharge rack 6-4, ensuring that the slipping mold can fall accurately onto the conveyor belt 6-2 and avoid skewing.

[0046] For example, such as Figure 1 As shown, the inner width dimension of the equipment frame 1 matches the size of the grinding wheel mold.

[0047] In some examples, by matching the dimensions, the grinding wheel mold can maintain its angle and position when moving within the equipment frame 1, without any skewing, and can stably feed the material.

[0048] In actual use: After fixing the equipment frame 1, install the hydraulic press 2 on its top. The bottom of the output end of the hydraulic press 2 is connected to the pressure head 3. The bottom of the equipment frame 1 is installed with the base frame 4. The rolling rod 5-1 of the feeding and pushing assembly 5 is rotatably connected inside the equipment frame 1. The inner surface of the equipment frame 1 is designed with an inclined structure so that the rolling rod 5-1 is arranged from high to low. The first cylinder 5-2 and the second cylinder 5-3 are installed on one side of the equipment frame 1, and the push plate 5-4 is connected to the output end of the cylinder. The conveying shaft roller 6-1 of the discharge separation assembly 6 is rotatably connected inside the base frame 4, and the conveyor belt 6-2 is fitted between the conveyor shaft rollers 6-1. The outer frame 6-3 is installed on one side of the equipment frame 1. One end of the outer frame 6-3 is equipped with an empty mold discharge rack 6-4 corresponding to the conveyor belt 6-2 on one side. The surface of the outer frame 6-3 is equipped with a drive motor 6-5, and the output end of the drive motor 6-5 is connected to a rotating frame 6-6. One end of the rotating frame 6-6 is equipped with a tilting separation rack 6-7. The rotating frame 6-6 and one side of the equipment frame 1 are connected. The third cylinder 6-8 is installed and the output end of the cylinder is connected to the clamping block 6-10. The empty mold discharge rack 6-4 has baffles 7 on both sides and the bottom is inclined. When in use, the mold is placed from the high side of the equipment frame 1 and slides down along the rolling rod 5-1. The first cylinder 5-2 and the second cylinder 5-3 push the mold to the pressing station below the hydraulic press 2 in sequence through the push plate 5-4. After the pressing head 3 presses down to complete the forming, the mold enters the flipping and separating rack 6-7. The third cylinders 6-8 on both sides drive the clamping block 6-10 to extend and clamp the mold. The drive motor 6-5 on the surface of the outer frame 6-3 drives the rotating frame 6-6 to flip the flipping and separating rack 6-7. Gravity and clamping force are used to separate the forming grinding wheel from the mold. The grinding wheel falls into the lower conveyor belt 6-2 and is transported to the finished product collection area. After the mold is reset with the flipping and separating rack 6-7, it is pushed to the empty mold discharge rack 6-4. After falling into the empty mold discharge rack 6-4, it falls into the other side conveyor belt 6-2 and is transported to the mold recycling area.
