Description

Technical Field

[0001] The present invention relates to the technical field of machinery for powder compression molding products, and specifically to a core vibration feeding device for die-pressed powder products and a powder product press. Background Art

[0002] Machinery for powder compression molding products is mainly used to press various powdered materials with a good ratio into green compacts or finished products with the required shape and density. The following problems exist in the use of traditional press equipment: First, manual feeding has low efficiency and poor uniformity; second, the automatic feeding device used is prone to jamming, and it is difficult to feed materials in the middle of the mold cavity; finally, the control of the feeding amount is not accurate, and the adjustment is not convenient, resulting in inconsistent densities of the finished products, affecting the accuracy and qualification rate of the products.

[0003] Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0004] In view of the above technical problems, the present invention provides a core vibration feeding device for die-pressed powder products and a powder product press. Through an automatic transmission structure, a high-frequency back-and-forth swing of the core is achieved to form a high-frequency vibration effect, and the powder material is evenly filled into the mold cavity to avoid jamming; finally, the densities of the finished products are consistent, improving the accuracy and qualification rate of the products; effectively solving the problem of powder flow balance.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A core vibration feeding device for die-pressed powder products includes a machine body, on which a feeding box assembly, a core, a mold outer ring and a swing mechanism are provided; the core is arranged at the center position of the mold outer ring, and a mold cavity is formed between the two; the feeding box assembly is located above the mold cavity and fills the powder material into it; the swing mechanism is connected to the core and drives it to swing back and forth.

[0007] During the process of the feeding box assembly filling the powder material into the mold cavity in this core vibration feeding device for die-pressed powder products, the swing mechanism drives the core to swing back and forth. The high-frequency back-and-forth swing of the core forms a high-frequency vibration effect, and the powder material is evenly filled into the mold cavity to avoid jamming; finally, the densities of the finished products are consistent, improving the accuracy and qualification rate of the products, and effectively solving the problem of powder flow balance.

[0008] As a further optimized solution, the swing mechanism includes a driving component and a connecting rod assembly; one end of the connecting rod assembly is connected to the core, and the other end is eccentrically connected to the rotating shaft of the driving component. When the rotating shaft of the driving component rotates, it drives the core to swing through the transmission of the connecting rod assembly.

[0009] For a further optimized solution, the connecting rod assembly includes a first connecting rod and a second connecting rod. One end of the first connecting rod is eccentrically connected to the rotating shaft of the driving component, the other end of the first connecting rod is rotatably connected to one end of the second connecting rod, and the other end of the second connecting rod is connected to the die core. The connecting rod assembly is formed by the rotational connection of the first connecting rod and the second connecting rod, with a simple structure and convenient and fast installation.

[0010] For a further optimized solution, the machine body further includes a die mounting plate, and the outer die is arranged on the die mounting plate. The outer die is installed through the die mounting plate, which is convenient for installation.

[0011] For a further optimized solution, the feeding box assembly is arranged above the die mounting plate; the feeding box assembly includes a feeding box, a moving cylinder, a feeding rod, and a feeding cylinder;

[0012] The feeding rod is arranged inside the feeding box, the feeding cylinder is installed on the feeding box and connected to the feeding rod, and the feeding cylinder drives the feeding rod to rotate periodically to assist in material dropping;

[0013] The moving cylinder is connected to the feeding box to drive it to move back and forth.

[0014] When the feeding box assembly feeds materials, the moving cylinder moves the feeding box forward to the position directly above the mold cavity, and the feeding cylinder drives the feeding rod to rotate periodically so that the powder material can fall into the mold cavity more quickly; after the feeding is completed, the moving cylinder moves the feeding box backward to leave the position above the mold cavity, making room for subsequent operations.

[0015] For a further optimized solution, a vibrating feeder and a storage bin are arranged above the feeding box assembly. The powder material in the storage bin falls downward into the vibrating feeder, and the vibrating feeder vibrates the powder material to feed it downward. The vibrating feeder makes the powder material in the storage bin fall quickly and evenly downward through vibration to fill the mold cavity.

[0016] A powder product pressing machine includes the die core vibrating feeding device for molding powder products as described in any one of the above.

[0017] For a further optimized solution, the machine body of the powder product pressing machine further includes an upper mold pressing head, a lower mold pressing head, a middle mounting plate, an upper lifting mechanism, and a lower lifting mechanism;

[0018] The upper mold pressing head and the lower mold pressing head are respectively cylindrical ring structures adapted to the mold cavity, and the lower mold pressing head is located below the mold cavity;

[0019] The upper lifting mechanism is connected to the upper mold pressing head and drives it to move up and down in the upper space of the mold cavity;

[0020] The middle mounting plate is fixed, and the lower mold pressing head is fixed on the middle mounting plate;

[0021] The lower lifting mechanism is arranged below the swinging mechanism and drives the swinging mechanism, the die core, the outer die and the feeding box assembly to move up and down.

[0022] In the initial position, the lower lifting mechanism drives the swinging mechanism, the die core, the outer die and the feeding box assembly to move upward. A die cavity is formed by enclosing among the die core, the outer die and the lower die punch. After the die cavity is filled with powder material, the upper lifting mechanism drives the upper die punch to move downward to contact the powder material in the die cavity. After continuing to move downward to trigger the pressure point, it is kept under pressure for a period of time. After the pressure holding ends, the molded powder product is formed. The upper lifting mechanism and the lower lifting mechanism return respectively, and the formed product is demolded.

[0023] In a further optimized solution, the body of the powder product press further includes a lower mounting plate, a die core seat and a connecting column;

[0024] The lower mounting plate is located below the middle mounting plate, and the lower lifting mechanism drives the lower mounting plate to move up and down;

[0025] The die core seat is rotatably arranged on the lower mounting plate, and the connecting column passes through the middle mounting plate to connect the die core and the die core seat;

[0026] The swinging mechanism is arranged on the lower mounting plate and is connected to the die core seat. The swinging mechanism drives the die core seat to swing, and the connecting column swings synchronously, thereby driving the corresponding swing of the die core.

[0027] In a further optimized solution, the upper lifting mechanism is an upper oil cylinder, the lower lifting mechanism is a lower oil cylinder, and the upper oil cylinder and the lower oil cylinder have the same structure and size; A connecting pipeline is arranged between the cylinder bodies of the upper oil cylinder and the lower oil cylinder, and it is configured to connect the connecting pipeline when the upper oil cylinder and the lower oil cylinder need to be linked.

[0028] The linkage of the upper oil cylinder and the lower oil cylinder is as follows: when the upper oil cylinder descends to a certain position and the upper die punch presses the powder material in the die cavity to reach a certain pressure, the lower oil cylinder and the upper oil cylinder synchronously descend to another position. This action enables both the upper part and the lower part to be evenly pressed during the product forming process, which is beneficial to the consistent density of the upper and lower parts of the formed product.

[0029] Since the upper oil cylinder and the lower oil cylinder have the same structure and size, after the cylinder bodies of the two are connected through the connecting pipeline, when the pressing reaches a certain pressure, the hydraulic oil at the piston rod end of the upper oil cylinder is connected to the piston rod end of the lower oil cylinder through the connecting pipeline. At this time, for every distance the upper oil cylinder presses downward, the lower oil cylinder synchronously retreats the same distance, so as to realize the linkage of the upper oil cylinder and the lower oil cylinder. The linkage of the upper oil cylinder and the lower oil cylinder corresponds to the floating pressing process during the product forming process.

[0030] In this structure, no additional hydraulic components such as proportional valves, flow control valves, and relief valves are required, nor are control components such as displacement sensors and controllers needed. This reduces the components of the powder product press and lowers the equipment cost. The mechanical linkage action is reliable through the hydraulic principle.

[0031] The die core vibration feeding device for molding powder products and the powder product press of the present invention have the following technical advantages compared with the prior art:

[0032] 1. The die core swings back and forth at a high frequency to form a high-frequency vibration effect, and the powder material is evenly filled into the die cavity, avoiding problems such as material jamming and uneven blanking;

[0033] 2. The automated feeding process reduces manual intervention and improves production efficiency;

[0034] 3. The density of the finally formed product is uniformly good, improving the product accuracy and qualification rate. Description of the Drawings

Specific embodiments

[0046] The present invention will be further described in detail below with reference to the embodiments in the drawings.

[0047] As Figures 1 to 10 shown, it is a specific embodiment of the die core vibrating feeding device for die-pressed powder products and the powder product pressing machine of the present invention.

[0048] As Figure 1 , Figure 2 and Figure 4 shown, the die core vibrating feeding device for die-pressed powder products in this embodiment includes a machine body 20, on which there are arranged a feeding box assembly 1, a die core 2, a die outer ring 3 and a swing mechanism 5; the die core 2 is arranged at the center position of the die outer ring 3, and a die cavity 4 is formed between the two; the feeding box assembly 1 is located above the die cavity 4 and fills powder materials into it; the swing mechanism 5 is connected to the die core 2 and drives it to swing back and forth.

[0049] During the process of the die core vibrating feeding device for die-pressed powder products filling powder materials into the die cavity, the swing mechanism drives the die core to swing back and forth. The high-frequency back-and-forth swing of the die core forms a high-frequency vibration effect, and the powder materials are evenly filled into the die cavity, avoiding material jamming; the density of the final product is consistent, improving the precision and qualification rate of the product, and effectively solving the problem of powder flow balance.

[0050] As Figures 7 to 10 shown, the swing mechanism 5 includes a driving component 5a and a connecting rod assembly 5b; one end of the connecting rod assembly 5b is connected to the die core 2, and the other end is eccentrically connected to the rotating shaft of the driving component 5a. When the rotating shaft of the driving component 5a rotates, through the transmission of the connecting rod assembly 5b, the die core 2 is driven to swing, and the driving component 5a is a pneumatic motor.

[0051] As Figure 8As shown, the connecting rod assembly 5b includes a first connecting rod 5c and a second connecting rod 5d. One end of the first connecting rod 5c is eccentric and rotatably connected to the rotating shaft of the driving member 5a through a bearing. The other end of the first connecting rod 5c is rotatably connected to one end of the second connecting rod 5d, and the other end of the second connecting rod 5d is fixedly connected to the die core 2. The connecting rod assembly 5b is formed by rotatably connecting the first connecting rod 5c and the second connecting rod 5d, with a simple structure and convenient and fast installation.

[0052] As Figure 2 shown, the body 20 of the die-pressed powder product die core vibrating feeding device further includes a die mounting plate 6, and the outer die 3 is arranged on the die mounting plate 6. The outer die 3 is installed through the die mounting plate 6, which is convenient for installation.

[0053] As Figure 1 and Figure 2 shown, the feeding box assembly 1 is arranged on the upper part of the die mounting plate 6; the feeding box assembly 1 includes a feeding box 1a, a moving cylinder 1b, a feeding rod 1c and a feeding cylinder 1d;

[0054] A feeding rod 1c is arranged inside the feeding box 1a, the feeding cylinder 1d is installed on the feeding box 1a and connected to the feeding rod 1c, and the feeding cylinder 1d drives the feeding rod 1c to rotate periodically to assist in blanking;

[0055] The moving cylinder 1b is connected to the feeding box 1a to drive it to move back and forth.

[0056] When the feeding box assembly 1 feeds materials, the moving cylinder 1b moves the feeding box 1a forward to the position directly above the die cavity 4, and the feeding cylinder 1d drives the feeding rod 1c to rotate periodically to make the powder material fall into the die cavity 4 more quickly; after the feeding is completed, the moving cylinder 1b moves the feeding box 1a backward to leave the position above the die cavity 4, making room for subsequent operations.

[0057] As Figure 3 and Figure 5 shown, a vibrating feeder 7 and a storage bin 8 are arranged on the upper part of the feeding box assembly 1. The powder material in the storage bin 8 falls downward into the vibrating feeder 7, and the vibrating feeder 7 vibrates the powder material to feed it downward. The vibrating feeder 7 makes the powder material in the storage bin 8 fall quickly and evenly downward and fill the die cavity 4 through vibration.

[0058] The present invention also discloses a powder product pressing machine, which includes the above-mentioned die-pressed powder product die core vibrating feeding device.

[0059] As Figure 2 shown, the body 20 of the powder product pressing machine further includes an upper die head 10, a lower die head 11, a middle mounting plate 12, an upper lifting mechanism 13 and a lower lifting mechanism 14;

[0060] The upper die pressing head 10 and the lower die pressing head 11 are respectively cylindrical ring structures adapted to the die cavity 4, and the lower die pressing head 11 is located at the lower part of the die cavity 4;

[0061] The upper lifting mechanism 13 is connected to the upper die pressing head 10 and drives it to move up and down in the upper space of the die cavity 4. The upper lifting mechanism 13 drives the upper die pressing head 10 to move up and down along the guide rail slider mechanism 18;

[0062] The middle mounting plate 12 is fixed, and the lower die pressing head 11 is fixed on the middle mounting plate 12;

[0063] The lower lifting mechanism 14 is arranged at the lower part of the swing mechanism 5 and drives the swing mechanism 5, the die core 2, the die outer ring 3 and the feeding box assembly 1 to move up and down.

[0064] In the initial position, the lower lifting mechanism 14 drives the swing mechanism 5, the die core 2, the die outer ring 3 and the feeding box assembly 1 to move upward. The die core 2, the die outer ring 3 and the lower die pressing head 11 enclose to form the die cavity 4. After filling the powder material in the die cavity 4, the upper lifting mechanism 13 drives the upper die pressing head 10 to move down to contact the powder material in the die cavity 4. Continuing to move down to trigger the pressure point and then holding the pressure for a period of time. After the pressure holding ends, the molded powder product is formed. The upper lifting mechanism 13 and the lower lifting mechanism 14 return respectively, and the molded product is demolded.

[0065] As Figure 7 shown, the molded product C is a cylindrical ring, and the powder material is a high-functional plastic (PTFE) mixed with a binder, etc. It is mainly used to produce high-performance seals, precision plastic bearings, etc.

[0066] As Figure 4 and Figure 6 shown, the body 20 of the powder product pressing machine further includes a lower mounting plate 15, a die core seat 16 and a connecting column 17;

[0067] The lower mounting plate 15 is located at the lower part of the middle mounting plate 12, and the lower lifting mechanism 14 drives the lower mounting plate 15 to move up and down;

[0068] As Figure 9 shown, the die core seat 16 is rotatably arranged on the lower mounting plate 15 through a bearing under pressure 19. As Figure 4 shown, the connecting column 17 passes through the middle mounting plate 12 to connect the die core 2 and the die core seat 16;

[0069] The swing mechanism 5 is arranged on the lower mounting plate 15 and is connected to the die core seat 16. The swing mechanism 5 drives the die core seat 16 to swing, and the connecting column 17 swings synchronously, thereby driving the die core 2 to swing accordingly.

[0070] As Figure 6 and Figure 7As shown, the mold mounting plate 6 and the lower mounting plate 15 are integrated by four columns 9, and the four columns 9 penetrate through the middle mounting plate 12. During the lifting process of the lower lifting mechanism 14, the mold mounting plate 6 and the lower mounting plate 15 are linked, that is, both of them act simultaneously.

[0071] The upper lifting mechanism 13 is an upper oil cylinder, and the lower lifting mechanism 14 is a lower oil cylinder. The upper oil cylinder and the lower oil cylinder have the same structure and size; there is a connecting pipeline between the cylinder bodies of the upper oil cylinder and the lower oil cylinder, and it is configured to be connected when the upper oil cylinder and the lower oil cylinder need to be linked.

[0072] The linkage of the upper oil cylinder and the lower oil cylinder is as follows: when the upper oil cylinder descends to a certain position and the upper mold pressing head presses the powder material in the mold cavity to reach a certain pressure, the lower oil cylinder and the upper oil cylinder synchronously descend to another position. This action enables the upper and lower parts to be evenly pressed during the product forming process, which is beneficial to the consistent density of the upper and lower parts of the formed product.

[0073] Since the upper oil cylinder and the lower oil cylinder have the same structure and size, after the cylinder bodies of the two are connected through the connecting pipeline, when the pressing reaches a certain pressure, the hydraulic oil at the piston rod end of the upper oil cylinder is connected to the piston rod end of the lower oil cylinder through the connecting pipeline. At this time, the lower oil cylinder retreats the same distance as the upper oil cylinder presses down, so as to realize the linkage of the upper oil cylinder and the lower oil cylinder. The linkage of the upper oil cylinder and the lower oil cylinder corresponds to the floating pressing process during the product forming process.

[0074] In this structure, there is no need to use additional hydraulic components such as proportional valves, flow control valves and overflow valves, nor control components such as displacement sensors and controllers, which reduces the components of the powder product press and lowers the equipment cost, and realizes reliable mechanical linkage through hydraulic principles.

[0075] This powder product press has the following two working modes:

[0076] The action process of working mode one is as follows:

[0077] 1. Press the start button when all components are in the original state;

[0078] 2. The lower oil cylinder rises (speed adjustable, position adjustable);

[0079] 3. When the lower oil cylinder rises in place, the feeding starts, and the feeding box moves forward to the position directly above the mold cavity for feeding;

[0080] 4. After the feeding is completed, the feeding box moves backward and returns to the original position;

[0081] 5. The upper oil cylinder descends (speed adjustable);

[0082] 6. The upper mold pressing head contacts the powder material in the mold cavity, triggers the pressure point, and the pump is turned on to maintain pressure;

[0083] 7. After the pressure maintaining is completed, the product is formed;

[0084] 8. The upper oil cylinder returns, the lower oil cylinder returns, and the demolding ends (the upper and lower oil cylinders can be set to return simultaneously or individually one after another, with adjustable speed and position).

[0085] The operation process of Working Mode 2 is as follows:

[0086] 1. Press the start button with all components in the original state;

[0087] 2. The lower oil cylinder rises (with adjustable speed and position);

[0088] 3. When the lower oil cylinder rises to the in-place position, the feeding starts, and the feeding box moves forward to the position directly above the mold cavity for feeding;

[0089] 4. After the feeding ends, the feeding box moves backward and returns to the original position;

[0090] 5. The upper oil cylinder descends (with adjustable speed);

[0091] 6. Floating pressing: After the upper oil cylinder descends to a certain position, the lower oil cylinder and the upper oil cylinder descend synchronously to another position (the speeds of the upper and lower oil cylinders are ensured to be synchronous);

[0092] 7. The lower oil cylinder stops moving, the upper oil cylinder descends, triggers the pressure point, and the pump is turned on for pressure holding;

[0093] 8. After the pressure holding ends, the product is formed;

[0094] 9. The upper oil cylinder returns, the lower oil cylinder returns, and the demolding ends (the upper and lower oil cylinders can be set to return simultaneously or individually one after another, with adjustable speed and position).

[0095] When pressing products with a relatively high pressing height, generally, the floating process steps need to be used. Floating means that when the green powder of the product is compressed under a certain pressure, the outer ring and the core of the mold retreat synchronously. This reduces the friction between the powder material and the walls of the outer ring and the core of the mold during pressing, making the density of the upper and lower parts of the product consistent. The outer ring and the core of the mold are driven by the lower oil cylinder, so the retreat of the lower oil cylinder drives the synchronous retreat of the outer ring and the core of the mold.

[0096] This die-pressed powder product core vibration feeding device and powder product pressing machine achieve a high-frequency reciprocating swing of the core through an automated transmission structure to form a high-frequency vibration effect, evenly filling the mold cavity with powder materials and avoiding material jamming; the density of the final product is consistent, improving the precision and qualification rate of the product; effectively solving the problem of powder flow balance.

[0097] In summary, as described in the specification and illustrated content, the present invention has been made into actual samples and tested through multiple uses. From the test results, it is proven that the invention can achieve the expected purpose, and its practicability is beyond doubt. The above-mentioned embodiments are only used to conveniently illustrate the content of the invention and are not a formal limitation thereof; any equivalent embodiments made by those with common general knowledge in the technical field without departing from the technical features and similar features of the present invention and using the technical content disclosed by the present invention to make partial changes or modifications all fall within the protection scope of the present invention.
