Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting equipment, in particular to a servo press with a stable structure. Background Art

[0002] A servo press is a press machine that utilizes a servo motor for operation. It can achieve full closed-loop control of pressure and displacement through the precise control of the servo motor, thereby achieving high precision and high efficiency in press assembly operations.

[0003] Servo presses typically have a large load capacity and a wide range of applications, capable of handling large or heavy workpieces. Currently, most servo presses on the market choose to install castings to meet the requirements of stamping structure installation and load-bearing. However, this method requires the installation of a large number of castings. The impact force generated during the stamping process can cause vibration and structural deformation between the castings, making it impossible to ensure the balance and stability of the stamping structure during the stamping process, which in turn makes it difficult to ensure processing quality and accuracy. Summary of the Invention

[0004] In view of the defects of the existing technology, the technical problem to be solved by the utility model is to provide a servo press with a stable structure. Different from using heavy castings to meet the installation and load-bearing requirements of the stamping structure, the structure is designed to have good stability and strong rigidity. At the same time, the overall weight of this structure is lighter, less material is used, the load on the equipment is small, the possibility of structural deformation is reduced, and it is conducive to high-quality and high-precision processing.

[0005] In order to solve the above technical problems, the present invention proposes a servo press with a stable structure, which adopts the following technical solutions:

[0006] A servo press with a stable structure includes a bed and a servo press body. The servo press body is fixed on the bed. The servo press body includes a stamping mechanism and a fixed load-bearing mechanism. The stamping mechanism is installed on the fixed load-bearing mechanism. The fixed load-bearing mechanism includes an upper plate, a load-bearing column and a lower plate. The upper plate and the lower plate are fixedly installed on the bed. At least two load-bearing columns are provided. The load-bearing columns are symmetrically arranged with the stamping mechanism as the center. The upper and lower ends of the load-bearing columns are respectively connected to the upper plate and the lower plate.

[0007] This structure, with the upper plate, load-bearing columns, and lower plate forming a fixed load-bearing mechanism, and the load-bearing columns symmetrically arranged around the stamping mechanism, reduces overall structural weight while maintaining stability and rigidity compared to methods that rely on cast components for support. The symmetrical layout not only disperses the impact and vibration generated during the stamping process but also reduces structural deformation, ensuring the press's stability and precision under high-speed, high-load operating conditions. Reasonable structural design and force distribution reduce stress concentration and wear between components, thereby extending the service life of the servo press and its key components.

[0008] Furthermore, it also includes a guide plate, with two guide holes symmetrically provided at each end of the guide plate. The load-bearing column slides in engagement with the guide holes, and the guide plate is fixedly mounted on the stamping mechanism. The guide plate slides in engagement with the load-bearing column through the guide holes at its ends, providing precise guidance for the movement of the stamping mechanism. This design effectively limits any unnecessary offset or shaking of the stamping mechanism outside of the vertical direction, thereby significantly improving the precision and stability of the stamping action. At the same time, the guide plate not only serves as a guide element, but also provides additional support for the entire stamping mechanism through its fixed installation on the stamping mechanism. This support, in conjunction with the load-bearing column, further enhances the rigidity of the entire servo press structure.

[0009] Preferably, two load-bearing side panels are provided at the lower end of the lower plate, symmetrically arranged, with the rear side walls of the load-bearing side panels fixedly connected to the bed. The layout of the load-bearing side panels effectively enhances the stability of the entire structure. As part of the supporting structure, the load-bearing side panels can share the weight of the lower plate and the components above it, preventing deformation caused by weight concentration, thereby ensuring the stable operation of the entire equipment. Furthermore, the fixed connection between the load-bearing side panels and the bed allows the impact force or vibration generated during the stamping process to be transmitted to the bed through the load-bearing side panels, thereby reducing relative movement and stress concentration between components and improving the durability and reliability of the equipment.

[0010] Preferably, the punching mechanism includes a screw, a push rod, a punch head, and a drive device. The screw is connected to the drive device, the push rod is sleeved outside the screw and threadedly connected to the screw, the punch head is fixed to the bottom of the push rod, and the guide plate is fixedly connected to the push rod. The drive device can precisely control the vertical movement distance of the push rod by rotating the screw. This precise control facilitates the control of the precision and depth of the punching. The fixed connection between the guide plate and the push rod ensures the smoothness of the push rod during movement, thereby ensuring that the motion trajectory of the punch head always remains on a predetermined straight line, helping to reduce vibration and noise during the punching process and improve processing quality.

[0011] Preferably, the machine tool further includes a bearing, the inner ring of which is fixedly connected to the screw, and the outer ring of which is fixed to the upper plate. By introducing the bearing, the screw no longer directly contacts the upper plate during rotation, allowing the screw to more smoothly transmit power to the push rod during rotation, thereby improving transmission efficiency. The bearing also ensures that the screw does not wobble or rock during rotation, thereby ensuring that the motion trajectory of the push rod and punch head remains on a predetermined straight line, improving processing precision and stability.

[0012] Preferably, the device further includes a fixing member fixedly mounted on the lower plate, with the push rod slidingly engaged with the inner wall of the fixing member. The fixing member includes a buffer washer, a shaft sleeve, and two shaft sleeve fixing flanges. Because the push rod moves stably under the guidance of the inner wall of the fixing member, the position control of the punch head during the punching process is more precise, which helps to reduce punching errors caused by push rod offset or shaking, thereby improving the processing accuracy and quality of the product.

[0013] Preferably, the machine bed includes two protective plates fixedly mounted on either side of the load-bearing side panels. The primary function of the protective plates is to provide a physical barrier to prevent the operator from accidentally contacting moving parts during machine operation, thereby enhancing the safety of the equipment.

[0014] In summary, this structurally stable servo press reduces the overall weight of the structure while ensuring structural stability and rigidity, ensuring smooth operation of the press under high-speed and high-load working conditions, thereby improving processing accuracy and quality.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0022] A servo press with a stable structure includes a bed and a servo press body. The servo press body is fixed on the bed. The servo press body includes a stamping mechanism 1 and a fixed load-bearing mechanism 2. The stamping mechanism 1 is installed on the fixed load-bearing mechanism 2. The fixed load-bearing mechanism 2 includes an upper plate 21, a load-bearing column 22 and a lower plate 23. The upper plate 21 and the lower plate 23 are fixedly installed on the bed. At least two load-bearing columns 22 are provided. The load-bearing columns 22 are symmetrically arranged with the stamping mechanism 1 as the center. The upper and lower ends of the load-bearing columns 22 are respectively connected to the upper plate 21 and the lower plate 23.

[0023] This structure, with the upper plate 21, load-bearing columns 22, and lower plate 23 forming the fixed load-bearing mechanism 2, and the load-bearing columns 22 arranged symmetrically around the stamping mechanism 1, reduces the overall weight of the structure while ensuring stability and rigidity compared to methods that use cast parts as load-bearing components. The symmetrical layout not only disperses the impact and vibration generated during the stamping process but also reduces structural deformation, ensuring the stability and precision of the press under high-speed, high-load operating conditions. Reasonable structural design and force distribution reduce stress concentration and wear between components, thereby extending the service life of the servo press and its key components.

[0024] Furthermore, it also includes a guide plate 3, two guide holes 31 are symmetrically provided at both ends of the guide plate 3, the load-bearing column 22 slides in conjunction with the guide hole 31, and the guide plate 3 is fixedly mounted on the stamping mechanism 1. The guide plate 3 forms a sliding fit with the load-bearing column 22 through the guide holes 31 at both ends, providing precise guidance for the movement of the stamping mechanism 1. This design effectively limits any unnecessary offset or shaking of the stamping mechanism 1 outside the vertical direction, thereby significantly improving the accuracy and stability of the stamping action. At the same time, the guide plate 3 not only serves as a guide element, but also provides additional support for the entire stamping mechanism 1 by being fixedly mounted on the stamping mechanism 1. This support function works together with the load-bearing column 22 to further enhance the rigidity of the entire servo press structure.

[0025] Preferably, two load-bearing side panels 24 are provided at the lower end of the lower plate 23. The two load-bearing side panels 24 are symmetrically arranged, and the rear side walls of the load-bearing side panels 24 are fixedly connected to the bed. The layout of the load-bearing side panels 24 effectively enhances the stability of the entire structure. As part of the supporting structure, the load-bearing side panels 24 can share the weight of the lower plate 23 and the components above it, preventing deformation caused by weight concentration, thereby ensuring the stable operation of the entire equipment. At the same time, the fixed connection between the load-bearing side panels 24 and the bed allows the impact force or vibration generated during the stamping process to be transmitted to the bed through the load-bearing side panels 24, thereby reducing relative movement and stress concentration between components and improving the durability and reliability of the equipment.

[0026] Preferably, the punching mechanism 1 includes a screw rod 11, a push rod 12, a punch head 13 and a driving device 14, wherein the screw rod 11 is connected to the driving device 14, the push rod 12 is sleeved on the outside of the screw rod 11 and is threadedly connected to the screw rod 11, the punch head 13 is fixed to the bottom of the push rod 12, and the guide plate 3 is fixedly connected to the push rod 12. The driving device 14 can accurately control the moving distance of the push rod 12 in the vertical direction by rotating the screw rod 11. This precise control is conducive to controlling the accuracy and depth of the punching. The fixed connection between the guide plate 3 and the push rod 12 ensures the stability of the push rod 12 during movement, thereby ensuring that the motion trajectory of the punch head 13 always remains on a predetermined straight line, which helps to reduce vibration and noise during the punching process and improve the processing quality.

[0027] Preferably, a bearing 4 is further included, the inner ring of which is fixedly connected to the screw rod 11, and the outer ring of which is fixed to the upper plate 21. By introducing the bearing 4, the screw rod 11 no longer directly contacts the upper plate 21 during rotation, allowing the screw rod 11 to more smoothly transmit power to the push rod 12 during rotation, thereby improving transmission efficiency. At the same time, the bearing 4 ensures that the screw rod 11 does not deflect or wobble during rotation, thereby ensuring that the motion trajectory of the push rod 12 and the punch head 13 always remains on a predetermined straight line, improving processing accuracy and stability.

[0028] Preferably, a fixing member 5 is further included, which is fixedly disposed on the lower plate 23, and the push rod 12 is slidably engaged with the inner wall of the fixing member 5. The fixing member 5 includes a buffer washer, a shaft sleeve, and two shaft sleeve fixing flanges. Since the push rod 12 moves stably under the guidance of the inner wall of the fixing member 5, the position control of the punch head 13 during the punching process is more precise, which helps to reduce punching errors caused by deviation or shaking of the push rod 12, thereby improving the processing accuracy and quality of the product.

[0029] Preferably, the bed includes two guard plates 6, which are fixedly arranged on both sides of the load-bearing side plates 24. The main function of the guard plates 6 is to provide a physical barrier to prevent the operator from accidentally contacting the moving parts during the operation of the machine, thereby enhancing the safety of the equipment.

[0030] In summary, this structurally stable servo press reduces the overall weight of the structure while ensuring structural stability and rigidity, ensuring smooth operation of the press under high-speed and high-load working conditions, thereby improving processing accuracy and quality.

[0031] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
