Description

Technical Field

[0001] This utility model belongs to the field of powder metallurgy shaping, and specifically relates to an automated feeding device for shaping irregularly shaped parts. Background Technology

[0002] The core function of a powder metallurgy forming machine is to perform "finishing" on sintered powder metallurgy parts to improve their dimensional accuracy, shape accuracy, and surface quality. Powder metallurgy forming machines can enhance the dimensional accuracy and surface quality of parts, and are particularly suitable for high-strength, complex-shaped parts (such as gears). They achieve higher density distribution through localized pressure, enhancing mechanical properties such as compressive strength and wear resistance. Currently, when shaping and feeding irregularly shaped parts that require circumferential positioning, manual feeding or complex electromechanical assembly mechanisms are generally used, resulting in low feeding efficiency and difficulty in automation. For these products, there is an urgent need for an automated feeding device. Utility Model Content

[0003] The purpose of this utility model is to provide an automated feeding device for shaping irregular parts. It can control the feeding pusher to move back and forth through a cam mechanism, take out the workpiece in the material bin of the conforming cavity component, and then send it to the bottom of the shaping machine for processing, so as to realize the automated completion of the material picking, pushing and feeding process.

[0004] The purpose of this utility model is achieved as follows: an automated feeding device for shaping irregularly shaped parts includes a shaping machine, on which a slider that can be raised and lowered is provided, and a fixed mounting base and a fixed base plate are also provided. A transverse rotating shaft is rotatably provided on the fixed mounting base via a support mechanism. A coaxial gear and a cam are installed at the end of the rotating shaft. A bracket is connected to the slider. A vertical rack is provided on the bracket. The rack is meshed with the gear. A movable seat that can move back and forth is installed on the fixed base plate via a guide mechanism. A second bracket and a feeding push plate are respectively connected to the movable seat. A cam follower corresponding to the cam is installed on the upper part of the second bracket. A contour cavity assembly is provided on the fixed base plate corresponding to the feeding push plate.

[0005] In operation, this invention places multiple stacked workpieces inside the hopper of the contour cavity assembly. The workpieces fall precisely into the workpiece picking hole of the feeding pusher plate. A rack is fixed to the support of the forming machine's slider. As the slider moves up and down, the gear in contact with the rack rotates relative to it. The cam is coaxial with the gear; when the gear rotates by a certain angle, the cam rotates by the same angle. The cam's profile curve is precisely designed. When the cam rotates, the cam follower in contact with it drives the feeding pusher plate on the moving seat to push the workpiece onto the forming machine, completing the feeding process. The feeding pusher plate corresponding to the contour cavity assembly moves back and forth on a linear guide rail. Precise adjustment of the feeding pusher plate's stop position completes the picking-pushing-feeding process. Compared with existing technologies, the advantages of this invention are: it can control the back-and-forth movement of the feeding pusher plate through a cam mechanism, automatically completing the picking, pushing, and feeding processes of the workpiece.

[0006] As a further improvement of this utility model, the rear parts of the fixed mounting base and the fixed base plate are both fixed to the shaping machine, and the fixed mounting base and the fixed base plate are arranged correspondingly on the left and right sides.

[0007] As a further improvement of this utility model, the support mechanism includes two bearing seats spaced apart from each other, both bearing seats being mounted on a fixed mounting base, and the rotating shaft being rotatably mounted on the two bearing seats.

[0008] As a further improvement of this utility model, the guiding mechanism includes two longitudinally arranged guide rails on the fixed base plate, and the movable seat is movably connected to the two guide rails. A cam mechanism drives the movable seat to move back and forth.

[0009] As a further improvement of this utility model, the second bracket is installed on the upper side of the movable seat, and a gap is left between the movable seat and the fixed seat plate. The feeding push plate is fixed to the lower part of the right side of the movable seat. The cam mechanism drives the feeding push plate on the movable seat to move back and forth.

[0010] As a further improvement of this utility model, a workpiece picking hole is vertically provided through the feeding push plate. The workpiece in the hopper can fall precisely into the workpiece picking hole.

[0011] As a further improvement of this utility model, the contouring cavity assembly includes a bracket three mounted on a fixed base plate. The bracket three has a mounting hole on its upper part, and a hopper cylinder is mounted on the mounting hole. Both the upper and lower ends of the hopper cylinder are open and extend outwards. The cylinder hole of the hopper cylinder corresponds to the workpiece, and the lower end of the hopper cylinder corresponds to the workpiece removal hole of the feeding pusher plate. The feeding pusher plate corresponds to the forming machine. When the workpiece inside the hopper cylinder falls precisely into the workpiece removal hole of the feeding pusher plate, the gear and rack mechanism drives the cam to rotate. The cam follower in contact with the cam drives the feeding pusher plate on the moving base to push the workpiece onto the forming machine. Attached Figure Description

Detailed Implementation

[0017] like Figure 1-4 As shown, an automated feeding device for shaping irregularly shaped parts includes a shaping machine 1, on which a slider 1a that can be raised and lowered is provided. It also includes a fixed mounting base 2 and a fixed base plate 3. The rear parts of the fixed mounting base 2 and the fixed base plate 3 are fixed to the shaping machine 1, and the fixed mounting base 2 and the fixed base plate 3 are arranged symmetrically on the left and right sides. A transverse rotating shaft 4 is rotatably mounted on the fixed mounting base 2 via a support mechanism. The support mechanism includes two bearing seats 13 spaced apart on the left and right sides, both bearing seats 13 being mounted on the fixed mounting base 2. The rotating shaft 4 is rotatably mounted on the two bearing seats 13. The rotating shaft 4 is rotatably mounted on the two bearing seats 13. The component is equipped with a coaxial gear 5 and a cam 6. A bracket 7 is connected to the slider 1a. A vertical rack 8 is provided on the bracket 7. The rack 8 meshes with the gear 5. A movable seat 9 that can move back and forth is installed on the fixed base plate 3 via a guide mechanism. The guide mechanism includes two longitudinally arranged guide rails 14 on the fixed base plate 3. The movable seat 9 is movably connected to the two guide rails 14. The cam 6 mechanism drives the movable seat 9 to move back and forth. A bracket 10 and a feeding push plate 11 are respectively connected to the movable seat 9. A cam 6 follower corresponding to the cam 6 is installed on the upper part of the bracket 10. A contour cavity assembly is provided on the fixed base plate 3 corresponding to the feeding push plate 11.

[0018] The bracket 2 10 is installed on the upper side of the movable seat 9. There is a gap between the movable seat 9 and the fixed seat plate 3. The feeding push plate 11 is fixed to the lower part of the right side of the movable seat 9. The cam 6 mechanism drives the feeding push plate 11 on the movable seat 9 to move back and forth.

[0019] The feeding pusher plate 11 has a vertical through-hole 15 for picking up workpieces. The workpieces in the hopper cylinder 17 can fall exactly into the workpiece picking hole 15.

[0020] The contouring cavity assembly includes a bracket 16 mounted on a fixed base plate 3. The bracket 16 has a mounting hole at its upper part, and a hopper 17 is mounted on the mounting hole. Both the upper and lower ends of the hopper 17 are open and extend outwards. The cylinder hole 17a of the hopper 17 corresponds to the workpiece. The lower end of the hopper 17 corresponds to the workpiece removal hole 15 of the feeding push plate 11, which corresponds to the forming machine 1. When the workpiece inside the hopper 17 falls into the workpiece removal hole 15 of the feeding push plate 11, the gear 5 and rack 8 mechanism drive the cam 6 to rotate. The follower of the cam 6 in contact with the cam 6 drives the feeding push plate 11 on the moving base 9 to push the workpiece onto the forming machine 1.

[0021] In operation, the material bin 17 of the contour cavity assembly contains multiple stacked workpieces. The workpieces fall precisely into the workpiece picking hole 15 of the feeding pusher plate 11. The rack 8 is fixed to the bracket 7 of the slider 1a of the forming machine 1. When the slider 1a moves up and down, the gear 5 in contact with the rack 8 rotates relative to it. The cam 6 is coaxial with the gear 5; when the gear 5 rotates by a certain angle, the cam 6 rotates by the same angle. The contour curve of the cam 6 is precisely designed. When the cam 6 rotates, the follower of the cam 6 in contact with it drives the feeding pusher plate 11 on the moving seat 9 to push the workpiece onto the forming machine 1, completing the feeding process. The feeding pusher plate 11 corresponding to the contour cavity assembly moves back and forth on the linear guide rail 14. The precise adjustment of the stopping position of the feeding pusher plate 11 back and forth completes the picking-pushing-feeding process. The advantage of this invention is that the feeding pusher plate 11 can be controlled to move back and forth through the cam 6 mechanism, automatically completing the picking, pushing, and feeding processes of the workpiece.
