Description

Technical Field

[0001] This invention relates to the field of screw presses, specifically to an energy-saving multi-station servo direct-drive screw press. Background Technology

[0002] Servo-driven direct-drive screw presses, as core equipment in modern forging and forming manufacturing, are widely used in precision forging fields such as automobiles, aerospace, and military industries due to their high precision, high efficiency, and excellent controllability. This equipment directly drives the screw mechanism via a servo motor, achieving precise control of the pressure head and thus completing the precision pressing of the workpiece.

[0003] However, in actual production, a long-standing and unresolved problem severely restricts production efficiency and product quality stability: the cleanliness of the mold working area. Under the high temperature and high pressure of forging, the press operation easily generates contaminants such as oxide scale, lubricant residue, cooling water, and tiny metal particles. If these impurities are not removed promptly, they will adhere to the lower surface of the pressure head and the worktable where the mold is mounted, affecting work efficiency. Therefore, existing servo direct-drive screw presses suffer from low automation, incomplete cleaning, reduced production efficiency, and increased energy consumption in terms of mold and worktable cleaning. Thus, an energy-saving multi-station servo direct-drive screw press is needed. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving multi-station servo direct-drive screw press to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: an energy-saving multi-station servo direct-drive screw press, comprising a servo direct-drive screw press body, a drive motor fixedly connected to the top of the servo direct-drive screw press body, a worktable fixedly connected to the lower end of the interior of the servo direct-drive screw press body, an auxiliary drive mechanism rotatably connected inside the servo direct-drive screw press body for intervening when the pressure head on the servo direct-drive screw press body is upward, a reversing mechanism fixedly connected to one end of the auxiliary drive mechanism for changing the direction of movement of the internal cleaning mechanism, the cleaning mechanism being disposed inside the reversing mechanism, and a worktable cleaning device rotatably connected to the lower end of the reversing mechanism.

[0005] Preferably, the auxiliary drive mechanism includes a limiting groove, which is formed inside the body of the servo direct drive screw press. A drive shaft is fixedly connected to the lower end of the output shaft of the drive motor. A rotatable ring is connected to the surface of the drive shaft. A sleeve is rotatably connected inside the body of the servo direct drive screw press. A C-shaped groove is formed inside the sleeve. The rotatable ring is rotatably connected in the C-shaped groove inside the sleeve. An arc-shaped rod is fixedly connected to the lower end of the sleeve. Several rollers are rotatably connected inside the arc-shaped rod. One of the rollers is fixedly connected to the drive shaft. A transmission belt is connected between the rollers.

[0006] Preferably, the reversing mechanism includes a fixed box, which is fixedly connected to one end of the arc-shaped rod. A rotating rod is rotatably connected inside the fixed box. A transmission belt is connected between the rotating rod and one of the rotating rollers inside the arc-shaped rod. Two right-angle toothed plates are fixedly connected inside the fixed box, and they are arranged diagonally. A rectangular slide groove is opened inside the fixed box. A linear slide rail is opened inside the fixed box. A square slide groove is slidably connected inside the linear slide rail. A connecting rod is fixedly connected to the surface of the rotating rod.

[0007] Preferably, the cleaning mechanism includes a slide rod that is slidably connected inside a rectangular trough and simultaneously slidably connected within a slot on the surface of a connecting rod. A gear is fixedly connected to the lower end of the slide rod surface, a rhomboid frame is fixedly connected to the upper end of the slide rod surface, and a V-shaped rod is fixedly connected to the upper end of the slide rod. A water gun nozzle is rotatably connected to the upper end of the rhomboid frame. The water gun nozzle is connected to an external water tank, and an arc-shaped plate is fixedly connected to the bottom of the water gun nozzle. The V-shaped rod is slidably connected inside the arc-shaped plate. When the connecting rod drives the slide rod to move inside the rectangular trough, it will cause the gear to mesh with the right-angle gear plate, driving the V-shaped rod to change the direction of the water gun nozzle.

[0008] Preferably, the workbench cleaning device includes an L-shaped rotating rod, which is fixedly connected to the lower end of the rotating rod. The lower end of the fixed box is rotatably connected to a rotating shaft. A U-shaped frame is fixedly connected to the surface of the rotating shaft. A sliding sleeve is slidably connected to the surface of the U-shaped frame. The sliding sleeve is fixedly connected to one end of the L-shaped rotating rod. An air outlet duct is fixedly connected to the surface of the rotating shaft. The air outlet duct is connected to an external fan through a flexible hose.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, instead of simple fixed or unidirectional rinsing, the cleaning of the pressure head utilizes a clever mechanical structure to generate a composite motion trajectory that couples up-and-down reciprocating motion with left-and-right oscillation. This dynamic cleaning mode actively covers the entire complex surface of the pressure head, thus improving cleaning efficiency.

[0010] In this invention, the air outlet duct, which is fixedly installed on the rotating shaft, reciprocates at a certain angle, blowing compressed air from the external fan evenly onto the entire workbench surface, thereby quickly blowing away oxidized dander, residual moisture and oil stains, and completing the synchronous cleaning of the workbench surface.

[0011] In this invention, adhering substances are removed from the pressure head by spraying cleaning fluid, while the worktable is dried and cleaned by blowing with compressed air. These two processes are performed simultaneously and complement each other, ensuring the mold area is in an ideal state before the next pressing, thus greatly improving the consistency of product quality.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1 to 12 This invention provides a technical solution: an energy-saving multi-station servo direct-drive screw press, including a servo direct-drive screw press body 1, a drive motor 2 fixedly connected to the top of the servo direct-drive screw press body 1, a worktable 3 fixedly connected to the lower end of the servo direct-drive screw press body 1, an auxiliary drive mechanism 4 rotatably connected inside the servo direct-drive screw press body 1 for intervening when the pressure head on the servo direct-drive screw press body 1 is upward, a reversing mechanism 5 fixedly connected to one end of the auxiliary drive mechanism 4 for changing the movement direction of the internal cleaning mechanism 6, the cleaning mechanism 6 being disposed inside the reversing mechanism 5, and a worktable cleaning device 7 rotatably connected to the lower end of the reversing mechanism 5.

[0016] The auxiliary drive mechanism 4 includes a limiting groove 41, which is located inside the servo direct drive screw press body 1. The lower end of the output shaft of the drive motor 2 is fixedly connected to a drive shaft 42. A damped rotating ring 43 is connected to the surface of the drive shaft 42. A sleeve 44 is rotatably connected inside the servo direct drive screw press body 1. A C-shaped groove is opened inside the sleeve 44. The rotating ring 43 is rotatably connected in the C-shaped groove inside the sleeve 44. An arc-shaped rod 45 is fixedly connected to the lower end of the sleeve 44. Several rotating rollers 46 are rotatably connected inside the arc-shaped rod 45. One of the rotating rollers 46 is fixedly connected to the drive shaft 42. A transmission belt 47 is connected between the rotating rollers 46.

[0017] The reversing mechanism 5 includes a fixed box 51, which is fixedly connected to one end of the arc-shaped rod 45. A rotating rod 52 is rotatably connected inside the fixed box 51. A transmission belt 53 is connected between the rotating rod 52 and one of the rollers 46 inside the arc-shaped rod 45. Two right-angle toothed plates 54 are fixedly connected inside the fixed box 51 and are arranged diagonally. A rectangular slide groove 55 is opened inside the fixed box 51. A linear slide rail 56 is opened inside the fixed box 51. A square slide groove 57 is slidably connected inside the linear slide rail 56. A connecting rod 58 is fixedly connected to the surface of the rotating rod 52.

[0018] The cleaning mechanism 6 includes a slide rod 61, which is slidably connected inside a rectangular groove 55 and simultaneously slidably connected within a slot on the surface of a connecting rod 58. A gear 62 is fixedly connected to the lower end of the slide rod 61, and a diamond-shaped frame 63 is fixedly connected to the upper end of the slide rod 61. A V-shaped rod 64 is fixedly connected to the upper end of the slide rod 61. A water gun nozzle 65 is rotatably connected to the upper end of the diamond-shaped frame 63. The water gun nozzle 65 is connected to an external water tank, and an arc-shaped plate 66 is fixedly connected to the bottom of the water gun nozzle 65. The V-shaped rod 64 rests on the arc-shaped plate. The internal sliding connection of 66, when the connecting rod 58 drives the slide rod 61 to move inside the rectangular slide groove 55, will cause the gear 62 to mesh with the right-angle toothed plate 54, driving the V-shaped rod 64 to change the direction of the water gun nozzle 65. Each engagement forces the gear 62 to rotate 180 degrees and be in an inclined state, which cleans the pressure head of the servo direct-drive screw press body 1. Through the sliding cooperation between the V-shaped rod 64 and the arc plate 66, it is finally converted into a compound motion of the water gun nozzle 65, which combines up-and-down reciprocating motion with left-and-right oscillation. This compound motion ensures that the cleaning fluid can be sprayed onto the surface of the rising pressure head with a changing trajectory and angle, achieving thorough cleaning without dead angles.

[0019] The workbench cleaning device 7 includes an L-shaped rotating rod 71, which is fixedly connected to the lower end of the rotating rod 52. The lower end of the fixed box 51 is rotatably connected to a rotating shaft 72. A U-shaped frame 73 is fixedly connected to the surface of the rotating shaft 72. A sliding sleeve 74 is slidably connected to the surface of the U-shaped frame 73. The sliding sleeve 74 is fixedly connected to one end of the L-shaped rotating rod 71. An air outlet duct 75 is fixedly connected to the surface of the rotating shaft 72. The air outlet duct 75 is connected to an external fan through a flexible hose. The air outlet duct 75 reciprocates at a certain angle, blowing compressed air from the external fan evenly onto the entire surface of the workbench 3, thereby quickly blowing away oxide scale, residual moisture, and oil stains, and completing the synchronous cleaning of the workbench surface.

[0020] The method of use and advantages of this invention: The working process of this energy-saving multi-station servo direct-drive screw press is as follows: like Figures 1 to 12 As shown.

[0021] In use, the lower end of the output shaft of the drive motor 2 is fixedly connected to the drive shaft 42, and a dial ring 43 is mounted on the drive shaft 42 through a damping bearing. When the servo direct drive screw press body 1 finishes performing the pressing work, the drive shaft 42 rotates. At this time, due to the damping effect, the dial ring 43 rotates freely with the shaft and does not trigger subsequent actions.

[0022] When pressing is complete and the pressure head needs to return upwards, the rotation direction or speed of the drive shaft 42 changes. At this time, the motion state changes under the combined action of the damping force of the dial ring 43 and a sleeve 44 with a C-shaped groove with a specific trajectory inside. The dial ring 43 engages in the C-shaped groove of the sleeve 44 and transmits the rotational power of the drive shaft 42 to the sleeve 44, causing it to start rotating. The rotation of the sleeve 44 drives the arc-shaped rod 45 fixedly connected to its lower end to move synchronously. The arc-shaped rod 45 has a transmission system inside, including multiple rotating rollers 46 and a transmission belt 47, for smoothly transmitting power. Finally, the power is guided to the fixed box 51 fixedly connected to one end of the arc-shaped rod 45. At this time, the fixed box 51 is directly below the pressure head inside the servo direct-drive screw press body 1.

[0023] The power entering the fixed box 51 is divided into two paths. The first path drives the rotating rod 52 to rotate via the transmission belt 53. The connecting rod 58 on the rotating rod 52 rotates accordingly, and the slot on the connecting rod 58 drives the sliding rod 61 to make a strict up-and-down reciprocating linear motion within the rectangular sliding groove 55. The lower end of the sliding rod 61 is fixed with a gear 62, and the upper end is connected to a water gun nozzle 65 via a diamond frame 63 and a V-shaped rod 64. When the sliding rod 61 makes up-and-down reciprocating motion, the gear 62 at its lower end will periodically mesh with two diagonally arranged right-angled toothed plates 54 fixed to the inner wall of the fixed box 51. Each meshing forces the gear 62 to rotate 180 degrees and be in an inclined state, thus cleaning the pressure head of the servo direct-drive screw press body 1.

[0024] The top of the V-shaped rod 64 is nested within the arc-shaped plate 66 at the bottom of the water gun nozzle 65. Therefore, the vertical linear motion of the slide rod 61, combined with its periodic rotation, is ultimately converted into a composite motion of the water gun nozzle 65—a combination of reciprocating vertical motion and oscillating horizontal motion—through the sliding engagement of the V-shaped rod 64 and the arc-shaped plate 66. This composite motion ensures that the cleaning fluid is sprayed onto the surface of the rising pressure head at varying trajectories and angles, achieving thorough cleaning without any blind spots.

[0025] The second power source is the L-shaped rotating rod 71 at the lower end of the rotating rod 52. The rotational motion of the L-shaped rotating rod 71 is converted into the reciprocating oscillation of the rotating shaft 72 through the sliding of the sliding sleeve 74 connected to its end on a U-shaped frame 73. The air outlet duct 75, which is fixedly installed on the rotating shaft 72, then reciprocates at a certain angle, blowing the compressed air from the external fan evenly onto the entire surface of the workbench 3, thereby quickly blowing away oxide scale, residual moisture, and oil stains, completing the synchronous cleaning of the workbench surface.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
