Description

Technical Field

[0001] The utility model relates to the technical field of forging machines, in particular to a forging machine for machining mechanical parts. Background Art

[0002] Forging presses are machines used for cold working metals and machinery, changing only the metal's shape. With the invention of the electric motor, forging presses initially adopted centralized electric motor drive, but later became widely driven by individual electric motors. In the early 20th century, jig boring machines and thread grinders were developed to achieve higher-precision workpieces, fixtures, and threading tools. Simultaneously, various automatic machine tools, profiling machine tools, modular machine tools, and automated production lines were developed to meet the needs of mass production in industries such as automobiles and bearings.

[0003] In the prior art, patent number: CN214023289U discloses a forging machine for processing mechanical parts with a buffering function, including a base plate, support legs, a lower plate and a platform, the support legs are arranged on the surface of the base plate, the lower plate is fixed on the support legs, and a forging structure is arranged on the platform and the lower plate, the forging structure includes: a groove, a side rod, a placement table, a buffer part and a processing part, the groove is opened on the surface of the platform, the side rod is arranged on the surface of the base plate, the placement table is arranged at the upper end of the side rod and is located in the groove, the buffer part is arranged between the platform and the lower plate, and the processing part is arranged on the lower plate. The utility model has the functions of reducing the buffering effect during the forging process, reducing vibration, enhancing the forming effect of the workpiece, and straightening the workpiece to avoid deviation.

[0004] Although the above-mentioned forging machine can achieve the effect of increasing the buffering effect through the settings of springs and buffer rods, it still has the following shortcomings in actual applications: after the device is used for a long time, the elastic coefficient of the spring continues to decrease, resulting in a continuous decrease in the buffering effect, and the spring needs to be replaced frequently.

[0024] like Figure 1-4As shown, the utility model proposes a forging machine for machining mechanical parts, comprising a workbench 1, on the left and right inner walls of the workbench 1 are fixedly mounted bearing blocks 2 and servo motors 3, the output end of the servo motor 3 is fixedly connected to a bidirectional screw rod 4, the left and right inner walls of the workbench 1 are commonly fixedly connected to two slide rods 5, the outer peripheries of the bidirectional screw rod 4 and the slide rod 5 are symmetrically slidably sleeved with two moving blocks 6, the opposite sides of the moving blocks 6 are fixedly connected to two springs 7, and the springs 7 are movably sleeved on the outer periphery of the slide rod 5, the ends of the springs 7 away from the moving blocks 6 are fixedly connected to a connecting block 8, and the connecting blocks 8 are all slidably sleeved on the periphery of the slide rod 5, the top of the connecting block 8 is rotatably connected to the connecting rod 9, and the connecting rods 9 on the same side are crossed, and the intersection is rotatably connected to the rotating shaft 10, and a plurality of springs 11 are fixedly connected to the top inner wall of the workbench 1, and the bottom ends of the springs 11 are commonly fixedly connected to the buffer plate 12, and the bottoms of the buffer plates 12 are rotatably connected to the tops of the connecting rods 9, and the tops of the buffer plates 12 are fixedly connected to the placement plates 13, and the placement plates 13 pass through the top wall of the workbench 1, and a forging mechanism is fixedly installed on the top of the workbench 1 for forging parts placed on the placement plates 13.

[0025] In this embodiment: the forging mechanism includes a plurality of support columns 16 fixedly mounted on the top of the workbench 1, the top ends of the support columns 16 are fixedly connected to a mounting plate 17, and a hydraulic cylinder 18 is fixedly mounted on the top of the mounting plate 17, and the output end of the hydraulic cylinder 18 passes through the mounting plate 17 and is fixedly connected to a pressure plate 19.

[0026] Example 2

[0027] like Figure 1-4As shown, the utility model proposes a forging machine for machining mechanical parts. Compared with the first embodiment, a threaded hole and two sliding holes are provided on the moving block 6, which are matched with the bidirectional screw rod 4 and the sliding rod 5 respectively.
