Description

Technical Field

[0001] The invention relates to the field of metal powder forming, in particular to an automatic metal powder forming machine. Background Art

[0002] Powder or particle molding is one of the basic processes in powder or particle production. Its purpose is to make loose powder into semi-finished or finished products with predetermined geometric shape, size, density and strength. Among them, the most common way of powder molding is powder extrusion molding. Powder extrusion molding generally refers to a powder molding method that relies on the pressure of the punch to extrude the metal powder in the die into parts through an extrusion die with the same cross-sectional size and shape as the product.

[0003] Most of the existing metal powder forming machines are manually fed with materials. A scraper is connected to one end of the powder barrel. When feeding powder to the lower template, the scraper will push the formed metal product on one side to one side. At this time, the staff will manually pick it up. In order to ensure the forming effect of the metal product during the picking process, the subsequent template will be quickly pressed for the second time, which can easily cause accidents to the staff's hands. In addition, the staff will place the formed metal product in a collection box on one side. Due to the limitations of the processing environment, the box needs to be opened and closed reciprocally. In this process, it is not only difficult to ensure the safety of the staff themselves, but also reduces the overall forming efficiency of the device.

[0004] In summary, the above-mentioned mechanism is mostly operated manually during actual use, which not only makes it difficult to ensure the safety of the workers themselves, but also reduces the overall molding efficiency of the device. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an automatic metal powder forming machine to solve the technical problem that in actual use, most of the operations are performed manually, which not only makes it difficult to ensure the safety of the workers themselves, but also reduces the overall forming efficiency of the device.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic metal powder forming machine, comprising a shell, a powder barrel and a sliding plate, wherein the powder barrel is located at one side of the shell, and the sliding plate is located in the shell and slides in a vertical direction, a forming plate is arranged on the top of the sliding plate, and a lower template is detachably arranged on the forming plate, an upper template matching with the lower template is slidably arranged on the top of the shell, a fixed gear is rotatably arranged on the forming plate, and guide plates matching with the fixed gear are symmetrically slidably arranged on both sides of the forming plate;

[0007] A guide column that cooperates with the guide plate is elastically arranged in the shell, and an insertion rod is elastically arranged on one side of the guide column. A special-shaped gear is rotatably arranged on the side wall of the insertion rod. A collection box is installed on one side of the shell, and a cover plate that cooperates with the special-shaped gear is rotatably arranged on the collection box.

[0008] By adopting the above technical solution, the guide plate slides to both sides under the action of the transmission mechanism and the bidirectional threaded rod, so that the formed metal products slide to the middle of the two sets of guide plates, effectively preventing the metal products from scattering and falling. The insertion rod will drive the special-shaped gear to rotate, and through the cooperation with the transmission mechanism, the cover plate will flip at a certain angle on the top of the collection box. At this time, the cover plate seals the collection box to prevent the metal products in the collection box from being contaminated during the discharge of powder from the powder barrel. When it is subsequently reset, the cover plate releases the sealing work of the collection box, thereby completing the collection of metal products.

[0009] The present invention is further configured such that an array of adjusting tooth blocks are arranged on the top of the forming plate in a direction perpendicular to the guide plate, and an adjusting gear is rotatably arranged on the inner side of the guide plate and meshes with the adjusting tooth blocks, one end of the adjusting gear is connected to a one-way threaded rod, and a shift block cooperating with the one-way threaded rod is slidably arranged on the inner side of the guide plate.

[0010] Preferably, the adjusting gear in the guide plate is driven to rotate by adjusting the tooth block, and the shift block slides toward one end of the guide plate in cooperation with the one-way threaded rod. At this time, the formed metal product is located between the guide plates on both sides. When the guide plates are subsequently reset, the shift block will reset and slide, thereby enabling the shift block to push the metal products between the guide plates to slide into a collection box on one side.

[0011] The present invention is further configured such that an array of second gear blocks meshing with the fixed gear are provided at the bottom of the powder barrel, and a first transmission mechanism is connected to one end of the fixed gear, a bidirectional threaded rod is connected to one end of the first transmission mechanism, and a guide plate is symmetrically slidably provided on the outer wall of the bidirectional threaded rod.

[0012] Preferably, when the powder barrel slides to one side, the second tooth block drives the fixed gear on the forming plate to rotate, and drives the bidirectional threaded rod to rotate in cooperation with the first transmission mechanism, thereby realizing that the bidirectional threaded rod drives the guide plate to slide back and forth on the top of the forming plate.

[0013] The present invention is further configured such that an array of first tooth blocks meshing with special-shaped gears are installed on one side of the insertion rod, one end of the special-shaped gear is connected to a second transmission mechanism, and one end of the second transmission mechanism is connected to the cover plate.

[0014] Preferably, when the insertion rod slides downward under the action of the guide column, the first tooth block drives the special-shaped gear on one side to rotate, thereby causing the second transmission mechanism to drive the cover plate at the other end to flip.

[0015] The present invention is further configured such that a sliding plate is obliquely provided at one end of the forming plate at the collecting box, and the top of the sliding plate is configured to be smooth.

[0016] Preferably, the metal products are pushed toward the inside of the collection box by the action of the slide plate. Since the slide plate itself is smooth, it can be ensured that the outer wall of the slide plate will not accumulate metal products, thereby improving the collection effect of the collection box on metal products.

[0017] The present invention is further configured as follows: the first transmission mechanism includes a driving disk, a transmission belt and a driven disk; the driving disk and the driven disk are connected by a transmission belt; one end of the driving disk is connected to a fixed gear, and one end of the driven disk is connected to a bidirectional threaded rod; the diameter of the driving disk in the first transmission mechanism is greater than the diameter of its driven disk.

[0018] Preferably, when the fixed gear rotates under the action of the second tooth block, it will drive the active disk at one end to rotate, and under the action of the transmission belt, the driven disk will follow and rotate, thereby realizing the rotation of the bidirectional threaded rod on the forming plate. Since the diameter of the active disk in the first transmission mechanism is larger than the diameter of its driven disk, when the fixed gear drives the active disk to rotate, the driven disk will drive the bidirectional threaded rod to rotate several times, thereby ensuring the stability of the guide plate adjustment on the forming plate.

[0019] The present invention is further configured such that one end of the upper template is connected to a first cylinder, and the bottom end of the sliding plate is connected to a second cylinder.

[0020] Preferably, the first cylinder drives the upper template to press the lower template, thereby forming a metal product. After the pressing is completed, the second cylinder drives the sliding plate to slide downward. At this time, the formed metal product will be exposed on the top of the forming plate. During the subsequent filling of the lower template with the powder barrel, the second cylinder drives the sliding plate to reset upward again, so that the metal powder in the powder barrel can fill the interior of the lower template.

[0021] The present invention is further configured such that the inner wall of the guide plate is provided with a flexible protective cover, and the protective cover itself and the guide plate are detachably arranged.

[0022] Preferably, the flexible protective cover is provided to prevent direct contact between the guide plate and the metal product, thereby preventing wear between the guide plate and the metal product, and the detachable setting facilitates subsequent replacement and maintenance by the staff.

[0023] The present invention is further configured such that the contact surfaces between the two ends of the guide column and the insertion rod are both arranged in an arc shape, and a smooth surface is arranged on the arc end surface.

[0024] Preferably, the arc-shaped setting can prevent the guide column from getting stuck with the insertion rod during the sliding process, and the setting of the smooth surface reduces the sliding friction between the guide column and the insertion rod, thereby facilitating stable extrusion and resetting between the guide column and the insertion rod.

[0025] The present invention is further configured such that a rotating shaft is rotatably arranged on the cover plate at a middle position of the collecting box, and the cover plate and the collecting box are also connected by an elastic rope, a blocking block is provided on the top of the collecting box, and a balancing groove is symmetrically arranged on the cover plate, and the balancing groove is obliquely symmetrically arranged through the rotating shaft.

[0026] Preferably, when the guide plate pushes the formed metal products into the collection box, the gravity of the metal products themselves will impact the cover, causing the cover to flip open under the action of the rotating shaft. In this process, the metal products are directly discharged and collected into the collection box. Subsequently, the cover is sealed and reset under the action of the rotating shaft, and the cover is prevented from rotating by the action of the elastic rope. In this process, the cover is located at the top of the collection box for quick opening and closing.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention exposes the formed metal product on the top of the forming plate. At this time, the powder barrel moves to one side to push the formed metal product. During the movement, the second tooth block at the bottom of the powder barrel drives the fixed gear on the forming plate to rotate. Under the action of the transmission mechanism and the bidirectional threaded rod, the guide plate slides to both sides, so that the formed metal product slides to the middle of the two groups of guide plates, effectively preventing the metal product from scattering and sliding. When the powder barrel is reset later, the fixed gear reverses. At this time, the metal product slides to one side of the collection box under the pressure of the guide plate. In this process, the collection of the formed metal products is automatically completed;

[0029] 2. The present invention provides guide posts on the shell. When the guide plate slides to both sides under the action of the threaded rod, the guide posts on one side will be squeezed. At this time, the guide posts slide to one side so that the plug rod matched with it slides downward. In this process, the plug rod drives the special-shaped gear to rotate. Through the cooperation with the transmission mechanism, the cover plate is turned over at a certain angle on the top of the collection box. At this time, the cover plate seals the collection box to prevent the metal products in the collection box from being contaminated during the powder barrel discharge process. When resetting later, the guide posts are reset under the action of the elastic component. At this time, the cover plate releases the sealing work of the collection box, thereby completing the collection of metal products. No manual operation is required in this process, which greatly reduces the occurrence of accidents and improves the overall forming efficiency of the device.

[0030] 3. The present invention provides an array of adjusting tooth blocks on the bottom of the guide plate on the forming plate. When the guide plate slides to both sides through the fixed gear, the adjusting tooth block will drive the adjusting gear in the guide plate to rotate, and the shift block will slide toward one end of the guide plate in cooperation with the one-way threaded rod. At this time, the formed metal product is located between the guide plates on both sides. When the guide plate is reset subsequently, the shift block will reset and slide in cooperation with the one-way threaded rod, so that the shift block pushes the metal products between the guide plates to slide into the collection box on one side, thereby completing the collection of the metal products.

DETAILED DESCRIPTION

[0046] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] The following describes an embodiment of the present invention based on its overall structure.

[0048] First embodiment:

[0049] See also Figure 1-Figure 9An automatic metal powder forming machine shown in the figure comprises a shell 1, a powder barrel 5, a collecting box 8, a sliding plate 4, a transmission mechanism, a sealing mechanism and a feeding mechanism, wherein the powder barrel 5 is located at one side of the shell 1, and the sliding plate 4 is located in the shell 1 and slides in a vertical direction, and a forming plate 19 is arranged on the top of the sliding plate 4, and the forming plate 19 itself is 50 cm long, and a lower template 9 is detachably arranged on the forming plate 19, and the outer diameter of the metal product formed by the lower template 9 is 4 cm, and this arrangement ensures that in the subsequent pushing process, a plurality of formed metal products will be accumulated on the forming plate 19, and then the metal powder in the powder barrel 5 is filled into the lower template 9, and then an upper template 13 cooperating with the lower template 9 is slidably arranged at the top of the shell 1, and the metal powder in the lower template 9 is pressed by sliding the upper template 13 upward, thereby completing the forming of the metal product, and at this time the sliding plate 4 will slide downward, so that the formed metal product will be exposed to the top of the forming plate 19, and the powder barrel 5 will also slide to one side under the action of the driving component;

[0050] Since a fixed gear 12 is rotatably provided on the forming plate 19, and an array of second gear blocks 18 meshing with the fixed gear 12 is provided at the bottom of the powder barrel 5, when the powder barrel 5 slides under the action of the driving assembly, the fixed gear 12 on the forming plate 19 will be driven to rotate, and a first transmission mechanism 11 is connected to one end of the fixed gear 12, and a bidirectional threaded rod 10 is connected to one end of the first transmission mechanism 11, and a guide plate 20 is symmetrically slidably provided on the outer wall of the bidirectional threaded rod 10, and the bidirectional threaded rod 10 is driven to rotate under the cooperation of the fixed gear 12 and the first transmission mechanism 11, thereby realizing that the bidirectional threaded rod 10 drives the guide plate 20 to slide to both sides on the top of the forming plate, and in this process, the powder barrel 5 will push the formed metal product between the guide plates 20, and then the metal powder is refilled into the lower template 9 through the powder barrel 5;

[0051] Since a guide post 6 cooperating with the guide plate 20 is elastically provided in the shell 1, and an insertion rod 16 is elastically provided on one side of the guide post 6, the guide post 6 will be squeezed when the guide plate 20 slides to both sides, so that one end of the guide post 6 squeezes the insertion rod 16, and the insertion rod 16 will slide downward in this process. Since a special-shaped gear 15 is rotatably provided on the side wall of the insertion rod 16, and a collection box 8 is installed on one side of the shell 1, and a cover plate 7 cooperating with the special-shaped gear 15 is rotatably provided on the collection box 8, the special-shaped gear 15 will drive the cover plate 7 to flip over during the downward sliding of the insertion rod 16. At this time, the cover plate 7 will seal the top of the collection box 8, thereby preventing the metal products in the collection box 8 from being contaminated during the discharge of powder from the powder barrel 5;

[0052] After the powder discharge is completed, the powder barrel 5 will reset and slide to one side. At this time, the second tooth block 18 will drive the fixed gear 12 to rotate in the opposite direction. Under the action of the first transmission mechanism 11, the bidirectional threaded rod 10 will reverse, thereby causing the guide plate 20 to slide inward, so that the metal products inside the guide plate 20 can be arranged in order, and the guide plate 20 will release the extrusion on the guide column 6. Under the action of the elastic component, the plug rod 16 will reset and drive the special-shaped gear 15 to reverse. During this process, the cover plate 7 releases the sealing work on the collection box 8. In the process of the guide plate 20 sliding inward to squeeze the metal products, the excess metal products are discharged into the collection box 8. No manual operation is required in this process, which greatly reduces the occurrence of accidents and improves the overall forming efficiency of the device.

[0053] In the above embodiments, please refer to Figure 5 A first tooth block 17 meshing with the special-shaped gear 15 is installed on one side of the insertion rod 16, and one end of the special-shaped gear 15 is connected to the second transmission mechanism 14, and one end of the second transmission mechanism 14 is connected to the cover plate 7. When the insertion rod 16 slides downward under the action of the guide column 6, the first tooth block 17 will drive the special-shaped gear 15 on one side to rotate, thereby allowing the second transmission mechanism 14 to drive the cover plate 7 at the other end to flip, thereby enabling the cover plate 7 to complete the opening and closing of the collection box 8.

[0054] In the above embodiments, please refer to Figure 3 , wherein the first transmission mechanism includes a driving disc, a transmission belt and a driven disc, one end of the driving disc is connected to a fixed gear 12, and one end of the driven disc is connected to the bidirectional threaded rod 10. When the fixed gear 12 rotates under the action of the second tooth block 18, it will drive the driving disc at one end to rotate, and under the action of the transmission belt, the driven disc will follow and rotate, thereby realizing the rotation of the bidirectional threaded rod 10 on the forming plate 19. Since the diameter of the driving disc in the first transmission mechanism 11 is larger than the diameter of its driven disc, when the fixed gear 12 drives the driving disc to rotate, the driven disc will drive the bidirectional threaded rod 10 to rotate several times, and the stability of the guide plate 20 adjusted on the forming plate 19 is guaranteed in this process.

[0055] In the above embodiments, please refer to Figure 1One end of the upper template 13 is connected to the first cylinder 2, and the bottom end of the sliding plate 4 is connected to the second cylinder 3. Under the action of the first cylinder 2, it is easy to drive the upper template 13 to press the lower template 9, so as to process the metal product. After the pressing is completed, the second cylinder 3 drives the sliding plate 4 to slide downward. At this time, the formed metal product will be exposed to the top of the forming plate 19. In the subsequent process of the powder barrel 5 filling the lower template 9, the second cylinder 3 drives the sliding plate 4 to reset upward again, so that the metal powder in the powder barrel 5 can fill the interior of the lower template 9.

[0056] Second embodiment:

[0057] See also Figure 8 and Fig. 9 The automatic metal powder forming machine shown in the figure has an overall structure similar to that of the first embodiment, wherein an array of adjusting tooth blocks 22 are arranged on the top of the forming plate 19 in a direction perpendicular to the guide plate 20, and an adjusting gear 21 meshing with the adjusting tooth block 22 is rotatably arranged on the inner side of the guide plate 20, and the adjusting tooth block 22 will drive the adjusting gear 21 in the guide plate 20 to rotate. Since a one-way threaded rod 23 is connected to one end of the adjusting gear 21, and a shifting block 24 cooperating with the one-way threaded rod 23 is slidably arranged on the inner side of the guide plate 20, when the guide plate 20 slides to both sides through the fixed gear 12, the shifting block 24 slides toward one end of the guide plate 20 through the cooperation with the one-way threaded rod 23. At this time, the formed metal product is located between the guide plates 20 on both sides. When the guide plates 20 are reset subsequently, the shifting block 24 will reset and slide under the action of the one-way threaded rod 23, so that the shifting block 24 pushes the metal products between the guide plates 20 to slide into the collection box 8 on one side, thereby completing the collection of the metal products.

[0058] The third embodiment:

[0059] See also Fig.10The automatic metal powder forming machine shown in the figure is based on the first embodiment, wherein a rotating shaft 26 is rotatably arranged on the cover plate 7 and at the middle position of the collection box 8. When the guide plate 20 pushes the formed metal product into the collection box 8, the gravity of the metal product itself will impact the cover plate 7, so that the cover plate 7 is flipped open by the action of the rotating shaft 26. In this process, the metal product is directly discharged and collected into the collection box 8, and a blocking block 27 is provided on the top of the collection box 8, and a balancing groove 28 is symmetrically arranged on the cover plate 7, and the balancing groove 28 is arranged obliquely symmetrically through the rotating shaft 26. During the process of resetting and closing the cover plate 7, the cooperation of the blocking block 27 and the balancing groove 28 prevents the cover plate 7 from rocking back and forth, so that the cover plate 7 can be quickly closed at the top of the collecting box 8. The cover plate 7 and the collecting box 8 are also connected by an elastic rope 25, which can prevent the cover plate from rotating. At the same time, the elastic rope 25 also plays a role in elastic resetting of the cover plate 7. In this process, it is further ensured that the cover plate 7 is located at the top of the collecting box 8 for rapid opening and closing.

[0060] The present invention works as follows: when in use, the upper template 13 at the output end is driven by the first cylinder 2 to slide downward, and the metal powder is pressed and formed in cooperation with the lower template 9 on the forming plate 19, and then the second cylinder 3 drives the sliding plate 4 to slide downward. At this time, the formed metal product will be exposed to the top of the forming plate 19, and the powder barrel 5 will slide to one side under the action of the driving component. Since a fixed gear 12 is provided on the top of the forming plate 19, the fixed gear 12 is driven to rotate in the process of the powder barrel 5 pushing the metal product under the action of the second gear block 18 at the bottom of the powder barrel 5. Through the cooperation with the first transmission mechanism 11, the two groups of guide plates 20 slide to both sides through the bidirectional threaded rod 10, thereby causing the metal product to slide between the guide plates 20. In this process, the formed metal product is effectively prevented from scattering and sliding, so that it is arranged in order between the guide plates 20;

[0061] At the same time, when the guide plate 20 slides to both sides, the guide column 6 on the shell 1 will be squeezed. Since an insertion rod 16 is elastically provided in the vertical direction on one side of the guide column 6, the first tooth block 17 on the insertion rod 16 will drive the special-shaped gear 15 to rotate, and through the cooperation with the second transmission mechanism 14, the cover plate 7 on the top of the collection box 8 is flipped to complete the sealing of the collection box 8. In the subsequent resetting process of the powder barrel 5, the second cylinder 3 drives the sliding plate 4 to slide upward. At this time, the metal powder in the powder barrel 5 will refill the cavity of the lower template 9, and the guide plate 20 will slide inward to reset. During this process, the cover plate 7 releases the sealing work of the collection box 8, and the metal products will be squeezed into the collection box 8 during the inward sliding process of the guide plate 20. No manual operation is required in this process, which greatly reduces the occurrence of accidents and improves the overall forming efficiency of the device.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
