Description

Technical Field

[0001] This utility model relates to the field of press technology, specifically a direct-drive servo press. Background Technology

[0002] A servo press is an advanced pressure processing equipment. Its working principle is to drive the pressure mechanism with a servo motor for precise control. It adopts an electric drive method, which has higher precision and controllability. With the development of industrial automation and intelligent manufacturing, servo presses have been widely used in various fields.

[0003] A search revealed a utility model patent with Chinese patent publication number CN221233142U, which discloses a fully automatic direct-drive servo press. The press includes a fixed mounting base with a connecting vertical plate welded to it. It also includes a fixing clamp mounted on the fixed mounting base and bolted to it. The clamp has a material fixing groove integrated with the clamp.

[0004] Currently, the platform for receiving items in presses is generally located directly below the output end of the hydraulic cylinder. Therefore, when workers pick up or place items, they are close to the output end of the hydraulic cylinder. If the start switch is accidentally triggered, it may cause abrasions and crush injuries to the workers, indicating room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a direct-drive servo press to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a direct-drive servo press, comprising a press body, a shifting assembly installed on the outside of the press body, the shifting assembly including a mounting base fixedly connected to the outer wall of one side of the press body, a mounting shaft rotatably connected inside the mounting base via a bearing, a motor fixedly mounted on the outer wall of one end of the mounting base, a gear coaxially fixedly mounted on the output end of the motor, a gear ring fixedly sleeved on the outer circumference of the mounting shaft, the gear meshing with the gear ring, and the number of teeth on the gear being half the number of teeth on the gear ring.

[0007] As a further preferred embodiment of this technical solution, a movable frame is fixedly sleeved on the top of the outer circumference of the mounting shaft. The movable frame has two grooves, which are symmetrically arranged. A positioning component is installed in each of the two grooves of the movable frame.

[0008] As a further preferred embodiment of this technical solution, a horizontally arranged baffle is fixedly connected to one side of the outer wall of the press body, and the top wall of the baffle is in contact with the bottom wall of the moving frame.

[0009] This system allows for loading and unloading of items away from the press output, improving operational safety. It also enables automatic material dropping during changes, increasing production efficiency. Starting the external motor drives the gear to rotate one revolution. The gear, through meshing, drives the gear ring to rotate half a revolution. The mounting shaft and moving frame are then rotated half a revolution by the gear ring. Due to the baffle, the item will not move downwards and will instead move to the bottom of the press output. After completing the task, the moving frame is rotated half a revolution again. During this process, one end of the extrusion column is pulled outwards, and the item will naturally fall into the collection box without requiring manual unloading.

[0010] As a further preferred embodiment of this technical solution, the positioning component includes two lead screws rotatably connected to the middle of one side inner wall and one end inner wall of the moving frame. Two limiting rods are slidably inserted into the middle of one side inner wall and one end inner wall of the moving frame. A limiting plate is rotatably connected to the end of each of the two lead screws that are close to each other. The two limiting plates are respectively fixedly connected to one end of the two adjacent limiting rods.

[0011] As a further preferred embodiment of this technical solution, a pressing column is slidably inserted into the inner wall of the other end of the movable frame, and a spring is sleeved on the outside of the pressing column, with both ends of the spring being fixedly connected to the pressing column and the movable frame, respectively.

[0012] Adjust the positions of the two limiting plates as needed, and drive the lead screw to rotate via the knob. It will then rotate and move along the moving frame. Since the limiting plates are restricted to translation by the two limiting rods, the lead screw can drive the limiting plates to move horizontally. At this time, pull one end of the extrusion column outward, and the tension of the spring is overcome and shortened. Place the object in one of the grooves of the moving frame, and then push the object between the two limiting plates to complete the positioning. Finally, release the restriction of the extrusion column, and the position of the object will be fixed.

[0013] As a further preferred embodiment of this technical solution, the press body includes a servo motor, a high-precision ball screw, a pressure sensor, a control box, and a human-machine interaction module. The servo motor is fixed to the inner wall of the top of the press body, and the output end of the servo motor is fixedly connected to the ball screw, and the press head is fixedly connected to one end of the ball screw.

[0014] As a further preferred embodiment of this technical solution, a horizontally arranged extension platform is fixedly connected to the bottom of one side of the outer wall of the press body, and a collection frame is placed on the top of the extension platform, with the collection frame located on one side of the bottom of the baffle.

[0015] This utility model provides a direct-drive servo press, which has the following advantages:

[0016] (1) By setting up a replacement component, a baffle and a moving frame, this utility model can realize the work of picking up and putting down items away from the output end of the press, which is conducive to improving the safety of operation. In addition, it can automatically drop the material during replacement, which is conducive to improving production efficiency. Start the motor outside the mounting base. The output end of the motor drives the gear to rotate one revolution. The gear drives the gear ring to rotate half a revolution through meshing. The mounting shaft and the moving frame will be driven to rotate half a revolution by the gear ring. Due to the presence of the baffle, the object will not move downward. Then it will move to the bottom of the output end of the press body. After the work is completed, drive the moving frame to rotate half a revolution again. During this period, pull one end of the extrusion column outward. The object will fall naturally into the collection box without the need for material picking operation.

[0017] (2) By setting up a positioning component, the position of the two limiting plates can be adjusted as needed. The screw is driven to rotate by the knob and will move along the moving frame. Since the limiting plates are restricted to translation by the two limiting rods, the screw can drive the limiting plates to move in the horizontal direction. At this time, one end of the extrusion column is pulled outward, the tension of the spring is overcome and shortened. The object is placed in one of the grooves of the moving frame, and then the object is pushed between the two limiting plates to complete the positioning. Finally, the restriction of the extrusion column is released, and the position of the object will be fixed. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 3 As shown, in this embodiment, a direct-drive servo press includes a press body 1. A shifting component 5 is installed on the outside of the press body 1. The shifting component 5 includes a mounting base 501 fixedly connected to the outer wall of one side of the press body 1. A mounting shaft 502 is rotatably connected inside the mounting base 501 through a bearing. A motor 504 is fixedly installed on the outer wall of one end of the mounting base 501. A gear 505 is coaxially fixed at the output end of the motor 504. A toothed ring 503 is fixedly sleeved on the outer circumference of the mounting shaft 502. The gear 505 meshes with the toothed ring 503, and the number of teeth of the gear 505 is half the number of teeth of the toothed ring 503.

[0025] A movable frame 7 is fixedly sleeved on the top of the outer circumference of the mounting shaft 502. The movable frame 7 has two grooves, which are symmetrically arranged. A positioning component 6 is installed in each of the two grooves of the movable frame 7.

[0026] like Figure 1 As shown, a horizontally arranged baffle 4 is fixedly connected to one side of the outer wall of the press body 1. The top wall of the baffle 4 is in contact with the bottom wall of the moving frame 7. Due to the presence of the baffle 4, the object will not move downward.

[0027] Start the motor 504 outside the mounting base 501. The output end of the motor 504 drives the gear 505 to rotate one revolution. The gear 505 drives the gear ring 503 to rotate half a revolution through meshing. The mounting shaft 502 and the moving frame 7 will be driven to rotate half a revolution by the gear ring 503. Then the object will move to the bottom of the output end of the press body 1. After the work is completed, drive the moving frame 7 to rotate half a revolution again. During this period, pull one end of the extrusion column 604 outward. The object will fall naturally into the collection frame 3 without the need for material removal.

[0028] like Figure 2 and Figure 4 As shown, the positioning component 6 includes two lead screws 601 rotatably connected to the middle of one side inner wall and one end inner wall of the moving frame 7. Two limiting rods 602 are slidably inserted into the middle of one side inner wall and one end inner wall of the moving frame 7. A limiting plate 603 is rotatably connected to the end of the two lead screws 601 that are close to each other. The two limiting plates 603 are fixedly connected to one end of the two adjacent limiting rods 602 respectively.

[0029] A pressing column 604 is slidably inserted into the inner wall of the other end of the movable frame 7. A spring 605 is sleeved on the outside of the pressing column 604. The two ends of the spring 605 are fixedly connected to the pressing column 604 and the movable frame 7, respectively.

[0030] Adjust the positions of the two limiting plates 603 as needed, and drive the lead screw 601 to rotate via the knob. It will rotate and move along the moving frame 7. Since the limiting plates 603 are restricted by the two limiting rods 602 and can only move horizontally, the lead screw 601 can drive the limiting plates 603 to move horizontally. At this time, pull one end of the extrusion column 604 outward, and the tension of the spring 605 is overcome and shortened. Place the object in one of the grooves of the moving frame 7, and then push the object between the two limiting plates 603 to complete the positioning. Finally, release the restriction of the extrusion column 604, and the position of the object will be fixed.

[0031] like Figure 1 As shown, the press body 1 includes a servo motor, a high-precision ball screw, a pressure sensor, a control box, and a human-machine interface module. The servo motor is fixed to the inner top wall of the press body 1, and its output end is fixedly connected to the ball screw. The press head is also fixedly connected to one end of the ball screw. The servo motor serves as the drive source, achieving precise control through electrical control. The servo driver receives signals from the control box or the human-machine interface module and drives the servo motor to rotate according to a predetermined program. The servo motor drives the high-precision ball screw to move, and the ball screw converts the rotational motion of the motor into linear motion, thereby achieving precise position control of the press head. By analyzing the position signal fed back by the encoder through the servo motor, real-time monitoring and adjustment of the press head position can be achieved. The pressure sensor installed at the front end of the press head collects pressure data in real time and feeds the data back to the control box or the human-machine interface module. This equipment is existing technology and will not be described in detail here.

[0032] like Figure 1 As shown, a horizontally arranged extension platform 2 is fixedly connected to the bottom of the outer wall of one side of the press body 1. A collection frame 3 is placed on the top of the extension platform 2, and the collection frame 3 is located on one side of the bottom of the baffle 4. Unrestrained objects will fall directly into the collection frame 3 for centralized processing.

[0033] This utility model provides a direct-drive servo press, the specific working principle of which is as follows:

[0034] When the device is working, adjust the positions of the two limiting plates 603 as needed, and drive the lead screw 601 to rotate via the knob. The lead screw 601 will then rotate and move along the movable frame 7. Since the limiting plates 603 are restricted to translation by the two limiting rods 602, the lead screw 601 can drive the limiting plates 603 to move horizontally. At this time, pull one end of the extrusion column 604 outwards, overcoming the tension of the spring 605 and shortening it. Place the object in one of the grooves in the movable frame 7, and then push the object between the two limiting plates 603 to complete the positioning. Finally, release the restriction of the extrusion column 604, and the object will be positioned... The object will be fixed in place. Then, the motor 504 outside the mounting base 501 will be started. The output end of the motor 504 will drive the gear 505 to rotate one revolution. The gear 505 will drive the gear ring 503 to rotate half a revolution through meshing. The mounting shaft 502 and the moving frame 7 will be driven to rotate half a revolution by the gear ring 503. Due to the presence of the baffle 4, the object will not move downwards. It will then move to the bottom of the output end of the press body 1. After completing the work, the moving frame 7 will be driven to rotate half a revolution again. During this period, one end of the extrusion column 604 will be pulled outwards, and the object will fall naturally into the collection frame 3 without the need for material removal.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
