Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to a feeding device for a fully automatic forming hydraulic press. Background Technology

[0002] A hydraulic press is a tool used in conjunction with a mold to pressurize raw materials and shape them. Existing fully automatic hydraulic presses for forming small materials such as powders and scrap metal include a worktable with several forming grooves. A lifting mechanism is located below the worktable, with several lifting ends positioned relative to the forming grooves. The gaps between the lifting ends and the forming grooves form pressure chambers. A hydraulic mechanism is located above the worktable. A hopper and a movable mechanism are sequentially arranged on one side of the worktable. The movable mechanism drives the hopper to feed material into the pressure chambers. After the hydraulic mechanism presses the raw material into shape in the pressure chambers, the lifting mechanism lifts the shaped workpiece. The movable mechanism then drives the hopper to move and push the workpiece out until the hopper moves to the feeding position. The lifting ends of the lifting mechanism then descend and again form pressure chambers with the forming grooves. This reciprocating motion results in high workpiece forming efficiency.

[0003] However, existing fully automatic forming hydraulic press feeding devices have a simple structure, consisting only of a hollow bottom hopper connected to the worktable. The raw material in the hopper is moved back and forth relative to the pressure chamber by a moving mechanism, causing the raw material to fall into the pressure chamber by its own gravity. Although small fragments are small in individual volume and have relatively small gaps between them, there are many small fragments per unit volume, resulting in differences in the quality of raw material in each pressure chamber and uneven feeding. Since the moving end of the hydraulic mechanism travels a uniform distance, the workpieces formed under pressure have different densities even though they have the same volume, affecting product quality. Therefore, it is necessary to design a fully automatic forming hydraulic press feeding device with more uniform feeding. In view of this, we propose a fully automatic forming hydraulic press feeding device. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a feeding device for a fully automatic forming hydraulic press to solve the technical problem of uneven feeding in current fully automatic forming hydraulic press feeding devices.

[0005] To achieve the objective of this invention, the technical solution adopted is as follows: A fully automatic forming hydraulic press feeding device is designed, comprising a hopper. The bottom of the hopper has several sets of through holes, with two through holes in each set. A connecting mechanism is attached to each through hole; the connecting mechanism has a hollow structure. A feeding and compacting mechanism is provided on the connecting mechanism.

The number of transmission components is half the number of the feeding and compacting mechanisms. Each transmission component has two rotating output ends, which are connected to the input end of the feeding and compacting mechanism.

[0006] Preferably, the hopper includes a vertical section, and a flow guide is connected to the lower end of the vertical section. The inner wall of the flow guide has a symmetrical arc structure on both sides. The through hole is fixed at the bottom end of the flow guide. The gap between the vertical section and the flow guide forms an operating cavity.

[0007] Preferably, the connecting mechanism includes an outer ring and an inner ring, the outer ring is fixed to the bottom end of the guide portion, the inner ring is disposed in the cavity of the outer ring, and the inner ring and the outer ring are connected by a plurality of connecting strips, and the inner ring is provided with a movable groove.

[0008] The top of the connecting strip has a pointed structure;

[0009] The movable groove is composed of symmetrically arranged ascending grooves and descending grooves. Both the ascending grooves and the descending grooves have a semi-spiral structure. The ascending grooves and the descending grooves are connected end to end, and the connection between the ascending grooves and the descending grooves is provided with rounded corners.

[0010] Preferably, the feeding and compaction mechanism includes a rotating rod, which is movably mounted on the inner ring. A movable block is rotatably mounted on the rotating rod relative to the movable groove. The movable block is movably connected to the movable groove. A pressure plate is fixedly mounted at the bottom end of the rotating rod, and the outer end of the pressure plate is in contact with the inner wall of the guide tube.

[0011] The pressure plate is semi-spiral.

[0012] Preferably, the rotating assembly includes a main shaft and a motor. The main shaft is disposed in the operating cavity, and the two ends of the main shaft are rotatably connected to the two ends of the operating cavity through bearings. The motor is fixed to one side of the hopper, and the output shaft of the motor passes through the side wall of the hopper and is fixedly connected to the main shaft.

[0013] Preferably, the transmission assembly includes a first gear and a mounting strip. The first gear is fixedly mounted on the main shaft relative to the rotating rod. The mounting strip is disposed in the gap between the first gear and the rotating rod. Both ends of the mounting strip are fixedly connected to both ends of the operating cavity. Two rotating seats are symmetrically arranged on the mounting strip relative to the first gear. A connecting rod is rotatably mounted on the rotating seats via bearings. A limiting groove is formed at the bottom end of the connecting rod. A limiting slide rod is slidably mounted on the limiting groove. The bottom end of the limiting slide rod is fixedly connected to the top end of the rotating rod. A second gear is fixedly mounted at the top end of the connecting rod. The second gear meshes with the first gear. The rotation output end is composed of the connecting rod, the limiting slide rod, and the second gear.

[0014] Preferably, the agitation assembly includes a connecting ring and a spiral rod, the connecting ring and the spiral rod are arranged in an inner and outer structure, the connecting ring is fixed on the main shaft relative to the mounting strip, the spiral rod is fixedly connected to the connecting ring by a plurality of evenly arranged connecting rods, and the spiral rod is fixedly provided with a plurality of agitating plates in an equally spaced structure, the agitating plates being arranged in an inclined structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention provides a hollowed-out connecting mechanism at the bottom of the hopper, with a guide tube at the bottom of the connecting mechanism. The bottom of the guide tube contacts the worktable of the fully automatic forming hydraulic press. When the entire device moves to a set position under the control of the movable mechanism of the fully automatic forming hydraulic press, the guide tube connects with the pressure chamber. Power is provided by the feeding and compaction mechanism at the rotation output end of the transmission component, causing the feeding and compaction mechanism to send the raw material in the hopper to the pressure chamber of the fully automatic forming hydraulic press for preliminary compaction. This reduces the gap between raw materials and makes the quality of raw materials in multiple or multiple pressure chambers more similar, thus solving the technical problem of uneven feeding in current fully automatic forming hydraulic press feeding devices.

[0017] 2. This invention features a movable block rotatably connected to a movable groove on a rotating rod. The movable groove is composed of symmetrically arranged ascending and descending grooves, both of which have a semi-spiral structure and are connected end-to-end. This allows the movable block to move within the movable groove when the rotating rod rotates, causing the rotating rod to move up and down. This, in turn, causes the pressure plate to move up and down and rotate, resulting in better compaction of the material at its lower end by the pressure plate. This leads to a more uniform material feeding into the pressure chamber and a more consistent material delivery.

[0018] 3. By setting specific configurations for the rotating component and the transmission component, the present invention enables the rotating component and the transmission component to be driven by a single motor, resulting in a compact structure and reduced operating costs.

[0019] 4. By setting up an agitation component, the present invention agitates the raw materials in the hopper, keeping the raw materials in the hopper in an active state. This reduces the amount of raw materials falling all the way down the guide pipes. The raw materials in the hopper are trapped in the gaps between the guide pipes and the hopper, making it impossible to send the raw materials in the hopper into the pressure chamber of the fully automatic forming hydraulic press through the feeding and compaction mechanism.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] Example 1: A feeding device for a fully automatic forming hydraulic press, see [link / reference] Figures 1 to 6 The hopper includes a hopper 1. The bottom of the hopper 1 is provided with several sets of through holes, each set of two through holes. A connecting mechanism 2 is connected to the through holes. The connecting mechanism 2 has a hollow structure. A feeding and compacting mechanism 3 is provided on the connecting mechanism 2. A guide tube 4 is provided at the bottom of the connecting mechanism 2. The guide tube 4 is movably connected to the feeding and compacting mechanism 3. A transmission mechanism 5 is provided on the hopper 1.

[0035] The transmission mechanism 5 includes a rotating component 6 and several transmission components 7. Several agitating components 8 are evenly arranged on the movable end of the rotating component 6. The number of transmission components 7 is half the number of the feeding and compacting mechanisms 3. Each transmission component 7 has two rotating output ends, which are connected to the input ends of the feeding and compacting mechanisms 3. This invention establishes a hollowed-out connecting mechanism 2 at the bottom of the hopper 1, with a guide tube 4 at the bottom. The bottom end of the guide tube 4 contacts the worktable of the fully automatic forming hydraulic press. When the entire device moves to a set position under the control of the movable mechanism of the fully automatic forming hydraulic press, the guide tube 4 connects to the pressure chamber. Material is added to the hopper 1 manually or via an external feeding mechanism. Power is provided to the feeding and compacting mechanism 3 through the rotating output end of the transmission component 7, causing the feeding and compacting mechanism 3 to deliver the raw material from the hopper 1 to the pressure chamber of the fully automatic forming hydraulic press for preliminary compaction. This reduces the gaps between raw materials, making the quality of raw materials in multiple or repeated pressure chambers more similar, thus solving the technical problem of uneven feeding in current fully automatic forming hydraulic press feeding devices.

[0036] Specifically, the hopper 1 includes a vertical section 11, the lower end of which is connected to a guide section 12. The inner walls of the guide section 12 have symmetrical arc-shaped structures on both sides, and a through hole is fixed at the bottom of the guide section 12. The gap between the vertical section 11 and the guide section 12 forms an operating cavity. As a preferred embodiment of the present invention, by setting the inner walls of the guide section 12 to have symmetrical arc-shaped structures on both sides, the present invention allows the material in the guide section 12 to automatically fall to the bottom when the material in the hopper 1 is low. The bottom area is small, which reduces the dispersion of the material and facilitates output from the conduit 4. In addition, the arc-shaped structure makes the distance between the two ends of the guide section 12 and the agitator of the agitator 8 relatively consistent, which indirectly improves the agitation effect of the agitator 8.

[0037] Furthermore, the connecting mechanism 2 includes an outer ring 21 and an inner ring 22. The outer ring 21 is fixed at the bottom end of the guide portion 12, and the inner ring 22 is disposed in the annular cavity of the outer ring 21. The inner ring 22 and the outer ring 21 are connected by several connecting strips 23. A movable groove 24 is provided in the inner ring 22.

[0038] The top of the connecting strip 23 has a pointed structure; by setting the top of the connecting strip 23 to a pointed structure, the present invention makes it difficult for material to fall from the top of the connecting strip 23, and makes it easy for the raw material at the top of the connecting strip 23 to fall from the inclined surface of the top of the connecting strip 23 and fall into the guide tube 4 along the gap of the connecting mechanism 2.

[0039] The movable groove 24 consists of symmetrically arranged ascending grooves and descending grooves. Both ascending grooves and descending grooves have a semi-spiral structure. The ascending grooves and descending grooves are connected end to end, and the connection between the ascending grooves and descending grooves is provided with rounded corners.

[0040] Furthermore, the feeding and compaction mechanism 3 includes a rotating rod 31, which is movably mounted on the inner ring 22. A movable block 32 is rotatably mounted on the rotating rod 31 relative to the movable groove 24. The movable block 32 is movably connected to the movable groove 24. A pressure plate 33 is fixedly mounted at the bottom end of the rotating rod 31, and the outer end of the pressure plate 33 is in contact with the inner wall of the guide tube 4. This invention achieves this by setting the movable block 32 rotatably mounted on the rotating rod 31 to be movably connected to the movable groove 24, and by setting the movable groove 24 to be composed of symmetrically arranged rising grooves and falling grooves. Both the rising grooves and falling grooves have a semi-spiral structure. The head and tail are connected so that when the rotating rod 31 rotates, the movable block 32 moves in the movable groove 24. By setting a rounded corner at the connection between the rising groove and the falling groove, the movable block 32 is not easy to get stuck at the connection between the rising groove and the falling groove, so that the movable block 32 moves more smoothly in the movable groove 24, driving the rotating rod 31 to move up and down, so that the rotating rod 31 drives the pressure plate 33 to move up and down and rotate, so that the pressure plate 33 can better compact the material at its lower end multiple times, so that the quality fed into the pressure cavity is more uniform, and so that the feeding of the device is more uniform.

[0041] The pressure plate 33 is semi-spiral. This invention achieves this by setting the pressure plate 33 to a semi-spiral shape; see [link / reference]. Figure 4 The raw material enters through the opening of the pressure plate 33. The rotating pressure plate 33 continuously feeds the raw material in the guide tube 4 into the pressure chamber of the fully automatic forming hydraulic press. The bottom end of the pressure plate 33 is flush with the bottom end of the guide tube 4. The pressure plate 33 compacts the raw material at its lower end multiple times, so that the gap between the raw materials fed into the pressure chamber is smaller and the quality is relatively consistent.

[0042] It is worth noting that the rotating assembly 6 includes a main shaft 61 and a motor 62. The main shaft 61 is located inside the operating chamber, and both ends of the main shaft 61 are rotatably connected to both ends of the operating chamber via bearings. The motor 62 is fixedly mounted on one side of the hopper 1, and the output shaft of the motor 62 passes through the side wall of the hopper 1 and is fixedly connected to the main shaft 61. As a preferred embodiment of the present invention, the above-described arrangement allows the motor 62 to be controlled externally, and the rotation of the output shaft of the motor 62 can drive the main shaft 61 to rotate.

[0043] It is worth noting that the transmission assembly 7 includes a first gear 71 and a mounting strip 72. The first gear 71 is fixed on the main shaft 61 relative to the rotating rod 31. The mounting strip 72 is located in the gap between the first gear 71 and the rotating rod 31. Both ends of the mounting strip 72 are fixedly connected to both ends of the operating cavity. Two rotating seats 73 are symmetrically arranged on the mounting strip 72 relative to the first gear 71. A connecting rod 74 is rotatably mounted on the rotating seat 73 through a bearing. A limiting groove 75 is opened at the bottom end of the connecting rod 74. A limiting slide rod 76 is slidably mounted on the limiting groove 75. The bottom end of the limiting slide rod 76 is fixedly connected to the top end of the rotating rod 31. A second gear 77 is fixedly mounted at the top end of the connecting rod 74. The second gear 77 is meshed with the first gear 71. The rotation output end is composed of the connecting rod 74, the limiting slide rod 76, and the second gear 77. In a preferred embodiment of the present invention, the present invention, through the above-described arrangement, enables the main shaft 61 to rotate while simultaneously driving the first gear 71 to rotate. The rotation of the first gear 71 drives the second gear 77 and the connecting rod 74 to rotate. The rotation of the connecting rod 74 drives the limiting slide rod 76 and the rotating rod 31 to rotate. The limiting slide rod 76 can slide up and down relative to the limiting slide groove 75. By specifically configuring the rotating component 6 and the transmission component 7, the rotating component 6 and the transmission component 7 are driven by a single motor 62, resulting in a compact structure and reduced operating costs.

[0044] In addition, the agitation assembly 8 includes a connecting ring 81 and a screw rod 82. The connecting ring 81 and the screw rod 82 are arranged in an inner and outer structure. The connecting ring 81 is fixed on the main shaft 61 relative to the mounting strip 72. The screw rod 82 is fixedly connected to the connecting ring 81 through a plurality of evenly arranged connecting rods 83. A plurality of stirring plates 84 are fixedly arranged on the screw rod 82 at equal intervals. The stirring plates 84 are arranged in an inclined structure. As a preferred embodiment of the present invention, by setting the agitation assembly 8, the present invention agitates the raw materials in the hopper 1, so that the raw materials in the hopper 1 are in an active state, reducing the amount of raw materials falling all over the guide tube 4. The raw materials in the hopper 1 are in the gaps between the several guide tubes 4 and the hopper 1, and cannot be sent into the pressure chamber of the fully automatic molding hydraulic press by the feeding and compaction mechanism 3.

[0045] Working principle: When feeding material using this device, the moving mechanism of the fully automatic forming hydraulic press moves the entire device to the set position. The guide tube 4 is connected to the pressure chamber of the fully automatic forming hydraulic press. The motor 62 is controlled by an external controller. The output shaft of the motor 62 rotates, driving the main shaft 61 to rotate, which in turn causes the agitator 8 to rotate, agitating the raw material in the hopper 1 and keeping the raw material in the hopper 1 in an active state. The rotation of the main shaft 61 also drives the first gear 71 to rotate. The rotation of the first gear 71 drives the second gear 77 and the connecting rod 74 to rotate. The rotation of the connecting rod 74 drives the limit slide rod 7 6. Rotating rod 31 causes movable block 32 to move within movable groove 24, driving rotating rod 31 to move up and down along the inner wall of inner ring 22. This causes limiting slide rod 76 to slide up and down along limiting slide groove 75, causing rotating rod 31 to drive pressure plate 33 to move up and down and rotate. This allows pressure plate 33 to feed material, and when the material in the pressure chamber overflows, pressure plate 33 repeatedly compacts the material at its lower end. After feeding is completed, the motor 62 is controlled by external control, and the output shaft of motor 62 stops rotating (the remaining steps are the operation process of the fully automatic forming hydraulic press body, which will not be described in detail here).

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
