Technical Field

[0001] This utility model relates to the technical field of friction welding machine equipment, specifically a forging force balancing mechanism for a friction welding machine. Background Technology

[0002] Friction welding machines are welding equipment that uses frictional heat and upsetting force to join metal materials. They mainly generate frictional heat by rotating one workpiece relative to another stationary workpiece, which softens or melts the material at the contact surface. Then, upsetting force is applied to tightly connect the two workpieces. As an advanced welding technology, friction welding machines are widely used in many industrial fields due to their high efficiency and high quality.

[0003] Existing single-cylinder propulsion friction welding machines often suffer from uneven upsetting force during operation, resulting in uneven stress in the welding zone, which affects the quality of the welded joint and may even cause welding defects. In addition, the stability of the mechanical structure is also affected by the dynamic changes in force during upsetting. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that uneven upsetting force often exists in the existing single-cylinder propulsion friction welding machine during operation, which leads to uneven stress in the welding area, thereby affecting the quality of the welded joint and even causing welding defects. In addition, the stability of the mechanical structure is also affected by the dynamic changes in force during upsetting. Therefore, this utility model provides an upsetting force balancing mechanism for friction welding machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forging force balancing mechanism for a friction welding machine, comprising: a machine body, a balancing mechanism rear wall fixedly connected to one end of the top surface of the machine body, a spindle box provided at the other end of the top surface of the machine body, a main push cylinder provided at the center of the balancing mechanism rear wall, a slide table slidably connected to the top surface of the machine body, a balancing tie rod penetrating one end of the balancing mechanism rear wall, and locking nuts connected to both ends of the balancing tie rod.

[0007] As a further embodiment of this utility model: the slide is slidably connected to the top surface of the machine tool body between the rear wall of the balancing mechanism and the spindle box, and one side of the slide is fixedly connected to the moving end of the output shaft of the main push cylinder.

[0008] As a further improvement of this utility model: the slide table integrates a clamping structure for holding the workpiece, and the clamping structure is located on the side of the slide table facing the spindle box.

[0009] As a further embodiment of this utility model: the clamping structure in the slide table and the clamping structure in the spindle box are located on the same central axis and are arranged opposite each other, with the slide table clamping the workpiece and the internal driving element of the spindle box driving the clamping to rotate the workpiece.

[0010] As a further improvement of this utility model: the balance rod is synchronously inserted through the rear wall of the balance mechanism and the main shaft box and the insertion state is fixed by the locking nuts at both ends.

[0011] As a further improvement of this utility model, the balance rod and its connecting structure are provided in two sets, which are symmetrically distributed on both sides of the central axis of the spindle box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1.

The embodiments of this utility model will be described below based on its overall structure.

[0025] Reference Figures 1 to 6 In this embodiment of the present invention, a forging force balancing mechanism for a friction welding machine includes: a machine body 1, a balancing mechanism rear wall 2 fixedly connected to one end of the top surface of the machine body 1, a spindle box 3 provided at the other end of the top surface of the machine body 1, a main push cylinder 4 provided at the center of the balancing mechanism rear wall 2, a slide table 5 slidably connected to the top surface of the machine body 1, a balancing tie rod 6 penetratingly connected to one end of the balancing mechanism rear wall 2, and locking nuts 7 connected to both ends of the balancing tie rod 6.

[0026] Reference Figure 1 and Figure 2The balancing mechanism rear wall 2 and the spindle box 3 are respectively located at both ends of the top surface of the machine tool body 1. The spindle box 3 integrates a clamping structure for holding the workpiece and an electrical structure for driving its rotation. The slide table 5 is slidably connected to the top surface of the machine tool body 1 between the balancing mechanism rear wall 2 and the spindle box 3, and one side of the slide table 5 is fixedly connected to the moving end of the output shaft of the main push cylinder 4. The slide table 5 integrates a clamping structure for holding the workpiece, and the clamping structure is located on the side of the slide table 5 facing the spindle box 3. The clamping structure in the slide table 5 and the clamping structure in the spindle box 3 are located on the same central axis and are arranged opposite each other. The slide table 5 clamps and fixes the workpiece, and the internal driving element of the spindle box 3 drives the clamping to rotate the workpiece.

[0027] Using the above scheme: When welding the workpiece, the main push cylinder 4 applies the upsetting force during welding. The upsetting force is transmitted through the slide table 5 to the workpieces clamped by the slide table 5 and the spindle box 3 respectively, driving the spindle box 3 to rotate and perform rotary friction welding.

[0028] Reference Figures 3 to 6 The balance rod 6 is synchronously inserted through the rear wall 2 of the balance mechanism and the main spindle box 3 and is fixed in the inserted state by the locking nuts 7 at both ends. There are two sets of balance rods 6 and their connecting structures, which are symmetrically distributed on both sides of the central axis of the main spindle box 3.

[0029] The above scheme is adopted: the reverse force of the upsetting force is borne by the balance pull bar 6 and the locking nut 7 symmetrically distributed on both sides of the central axis of the spindle box 3, ensuring that the force structure of the upsetting force remains balanced throughout the welding process, so that the upsetting force is evenly distributed on the surface of the workpiece to ensure the welding quality.

[0030] The working principle of this utility model is as follows: During use, the two sets of balance levers 6 and locking nuts 7, the main force-bearing components, are symmetrically distributed on both sides of the central axis of the spindle box 3 to ensure that the upsetting force applied to the workpiece can be evenly transmitted to each support point. When welding the workpiece, the upsetting force is applied by the main push cylinder 4. The upsetting force is transmitted through the slide table 5 to the workpieces held by the slide table 5 and the spindle box 3 respectively. At the same time, the reverse force is borne by the symmetrical balance levers 6 and locking nuts 7, ensuring that the force structure of the upsetting force remains balanced throughout the welding process, so that the upsetting force is evenly distributed on the surface of the workpiece to ensure welding quality. Meanwhile, the equipment monitors the force changes during the welding process in real time through high-precision sensors and transmits the data to the central control system. The central control system uses advanced signal processing and machine learning algorithms to analyze the data in real time and identify anomalies. Once an anomaly is detected, the control system will immediately adjust the output force of the main push cylinder 4 through precise hydraulic control technology to ensure the stability of the welding force. The system will also coordinate other parameters of the welding equipment to maintain the overall stability and consistency of the welding process, thereby significantly improving the welding quality and the reliability of the joint.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
