Description

Technical Field

[0001] This utility model relates to the field of press technology, specifically to an intelligent high-precision powder forming electro-hydraulic servo press. Background Technology

[0002] A powder forming press is a device used for forming and processing powdered materials. It primarily uses pressure to compress powdered materials into solid products of the desired shape and size. This equipment is crucial in manufacturing, especially in industries such as ceramics, metals, plastics, and chemicals. Powder forming presses can increase material density, enhance product mechanical strength, and facilitate subsequent processing. To better facilitate powder extrusion forming, an intelligent, high-precision electro-hydraulic servo powder forming press is proposed.

[0003] As disclosed in the authorization announcement number CN210817460U, a precision CNC powder molding press includes a machine body, a direct drive motor is provided on the top of the machine body, an upper pressure shaft is fixedly connected to the output end of the direct drive motor, the outer side wall of the upper pressure shaft is fixedly connected to the machine body, an upper template is fixedly connected to the end of the upper pressure shaft away from the direct drive motor by bolts, a frame is fixedly connected to the middle position of the machine body by bolts, a mold frame movement guide rail is provided on the inner side of the frame, the mold frame movement guide rail is fixedly connected to the machine body by bolts, the upper template is slidably connected to the mold frame movement guide rail, and a telescopic protective sleeve is fixedly connected between the upper template and the upper pressure shaft.

[0004] Although it achieves control through the control cabinet on the support frame, the powder in the cylinder is discharged from the material tube at the bottom of the cylinder to the loading rack on the side of the machine body. At the same time, the capacitive sensor installed on the material tube detects the powder supply to prevent the workpiece from being pressed when there is no powder or insufficient powder. Then, the powder supply servo mechanism drives the transmission rod to rotate counterclockwise, so that the loading rack rotates on the connecting block. At the same time, the drive cylinder is activated. The drive cylinder rotates with the rotation of the transmission rod and the loading rack, and the piston rod on it also rises at the same time, so that the loading rack can remain stable during the material receiving process, thereby ensuring that the powder falls stably into the lower template and avoiding the waste of powder material.

[0005] However, the existing press does not solve the problem that it is not convenient to rotate and input powder materials and blow away material residues during use, nor is it convenient to continuously feed and eject the powder solids from the lower die, thus affecting the effect of powder extrusion molding. Utility Model Content

[0006] The purpose of this invention is to provide an intelligent high-precision powder forming electro-hydraulic servo press to solve the problems mentioned in the background art, such as the inconvenience of rotating and inputting powder materials and blowing away material residues, which is not conducive to continuous feeding and ejection of powder solids from the lower die, thus affecting the effect of powder extrusion molding.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an intelligent high-precision powder molding electro-hydraulic servo press, comprising a machine body and a main hydraulic cylinder. The main hydraulic cylinder is installed at the top of the machine body, and a sliding seat is installed at the output end of the main hydraulic cylinder, which is slidably connected to a material tank. Two sets of upper molds are installed at the bottom of the sliding seat. Two sets of rotating seats are installed inside the machine body, and a lower mold is movably installed inside each of the rotating seats. Each lower mold has four sets of equally spaced mold holes inside, and an auxiliary hydraulic cylinder is installed inside each of the mold holes. A top plate is installed at the output end of each auxiliary hydraulic cylinder. A worm gear is installed on the outer wall of each lower mold, and a servo motor is installed on the outer wall of each rotating seat. A worm is installed at the output end of each servo motor, and the worm is movably connected to the rotating seat, and the worm meshes with the worm wheel. Two sets of air tanks are installed on one side of the machine body, and two sets of material tanks are installed on the other side of the machine body.

[0008] Preferably, each of the material tanks is equipped with a movable sleeve at its bottom, and a movable tube is movably installed inside the movable sleeve.

[0009] Preferably, the surface of each movable tube is fitted with a toothed ring, and a drive motor is installed at the bottom of the material tank on one side of each movable sleeve.

[0010] Preferably, each of the drive motors has a drive shaft installed at its output end, and each drive shaft has a drive gear fitted on its surface, with the drive gear meshing with the gear ring.

[0011] Preferably, a spiral conveying mechanism is installed at the bottom of each of the movable tubes, and an air pump is installed at the top of each of the gas tanks.

[0012] Preferably, a support frame is installed on the side wall of the machine body above the gas tank, and two sets of cylinders are installed at the top of each support frame.

[0013] Preferably, each cylinder has a push rod installed at its output end, and a nozzle is installed at the end of the push rod furthest from the cylinder.

[0014] Preferably, the output end of the air pump is equipped with a hose, and the hose is connected to the nozzle.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the press not only realizes convenient rotary input of powder materials and blowing of material residues, but also facilitates continuous feeding of the lower die and ejection of extruded powder solids, avoids residues affecting subsequent extrusion molding operations, and improves the effect of powder extrusion molding.

[0016] (1) By adding powder materials into the tank, the drive motor drives the drive gear to rotate through the drive shaft. The drive gear drives the movable tube to rotate inside the movable sleeve through the gear ring. The movable tube drives the screw conveyor to rotate, so that the screw conveyor is rotated above the mold hole. Then, the solenoid valve and screw conveyor at the bottom of the tank are opened. The screw conveyor transports the powder material into the mold hole and accumulates on the top plate surface. Then, the drive motor is opened in the opposite direction. The drive motor drives the screw conveyor to rotate and reset. The rotation directions of the two sets of screw conveyors are opposite, so that the two sets of screw conveyors are folded together to avoid interference with the sliding seat. The main hydraulic cylinder drives the sliding seat to move downward. The sliding seat drives the upper mold to move downward to the inside of the mold hole and continuously extrudes the powder material to extrude it into shape. After extrusion, the upper mold is reset. The servo motor drives the worm wheel to rotate the lower mold by a quarter circle through the worm. The auxiliary hydraulic cylinder drives the top plate to move upward. The top plate drives the extruded powder solid to move upward and be discharged. At this time, the above feeding steps are repeated to complete the replenishment of the empty mold holes.

[0017] (2) When the empty die hole after the material is ejected rotates to the nozzle position, the cylinder drives the nozzle to move above the die hole through the push rod. The air pump delivers the air inside the air tank to the nozzle through the hose and sprays it out through the nozzle, thereby blowing away the residue inside the die hole to prevent the residue from affecting the subsequent extrusion molding operation. Then, the above operation is repeated to carry out continuous extrusion molding operation. Attached Figure Description

Two sets of material tanks 2 are installed on the other side of the machine body 1.

[0026] Powder material is added into the material tank 2. The drive motor 18 is turned on, and the drive motor 18 drives the drive gear 20 to rotate via the drive shaft 19. The drive gear 20 drives the movable tube 23 to rotate inside the movable sleeve 21 via the gear ring 22. The movable tube 23 drives the screw conveyor mechanism 12 to rotate, thus rotating the screw conveyor mechanism 12 above the die hole 27. Then, the solenoid valve at the bottom of the material tank 2 and the screw conveyor mechanism 12 are opened. The screw conveyor mechanism 12 conveys the powder material into the die hole 27 and accumulates on the surface of the top plate 17. Then, the drive motor 18 is turned on in the opposite direction, and the drive motor 18 drives the screw conveyor mechanism 12 to rotate and reset. The two sets of screw conveyor mechanisms 12 rotate in opposite directions, thus... The two sets of screw conveyor mechanisms 12 are folded together to avoid interference with the sliding seat 4. Then, the main hydraulic cylinder 3 is opened, and the main hydraulic cylinder 3 drives the sliding seat 4 to move downward. The sliding seat 4 drives the upper mold 13 to move downward into the mold hole 27 and continuously extrudes the powder material to extrude the powder material into shape. After extrusion, the upper mold 13 is reset, the servo motor 24 is opened, and the servo motor 24 drives the worm wheel 25 through the worm 26 to drive the lower mold 15 to rotate a quarter circle. Then, the auxiliary hydraulic cylinder 16 is opened, and the auxiliary hydraulic cylinder 16 drives the top plate 17 to move upward. The top plate 17 drives the extruded powder solid to move upward and be discharged. At this time, the above feeding steps are repeated to complete the feeding work of the subsequent empty mold hole 27.

The drive gear 20 drives the movable tube 23 to rotate inside the movable sleeve 21 through the gear ring 22. The movable tube 23 drives the screw conveyor mechanism 12 to rotate, so that the screw conveyor mechanism 12 is rotated above the mold hole 27. Then, the solenoid valve at the bottom of the material tank 2 and the screw conveyor mechanism 12 are opened.
