[0024] See also Figures 1 to 3 The bidirectional pushing mechanism for the cold drawing machine of this embodiment includes a stretching motor 1, a pushing assembly 2, a fixing ring 3, a driving shaft 4, a driving sprocket 5, a driven shaft 6, a driven sprocket 7, a driving chain 8, a stretching car 9 and a clamp 10 and other components.

[0025] The output end of the stretching motor 1 is fixedly connected to the driving sprocket 5 via a rotating shaft 11. The driving sprocket 5 is fixedly connected to the driving shaft 4 at the center of the end away from the stretching motor 1. The outer wall of the driving shaft 4 away from the driving sprocket 5 is fixedly connected to a bearing seat for supporting and fixing the driving shaft 4.

[0026] The center of the driven sprocket 7 is fixedly connected to the driven shaft 6, and the outer walls of both ends of the driven shaft 6 are fixedly connected to bearing seats for supporting and fixing the driven shaft 6. The outer walls of the driving sprocket 5 and the driven sprocket 7 are jointly sleeved with a driving chain 8 to form a chain transmission mechanism.

[0027] The top of the stretching car 9 is fixedly connected with a clamp 10 for clamping the metal material to be processed. The bottom of the stretching car 9 is fixedly connected with a drive chain 8 so that the stretching car 9 can be driven to move on the track during chain transmission.

[0028] The pushing assembly 2 includes a hydraulic push rod 21, a connecting ring 22, a push rod 23, and a push plate 24. The output end of the hydraulic push rod 21 is positioned toward one end of the driven sprocket 7 and is fixedly connected to the push rod 23 via the connecting ring 22. The end of the push rod 23, away from the hydraulic push rod 21, is detachably connected to the push plate 24 via a flange, which is used to push metal materials.

[0029] During operation, the stretching motor 1 is activated, driving the driving sprocket 5 via the rotating shaft 11, which in turn drives the driven sprocket 7 via the chain 8, which in turn rotates synchronously. The chain drive propels the stretching cart 9 along the track, where the clamp 10 on the stretching cart 9 grips the metal material to be processed. Once the stretching cart 9 reaches the designated position, the push assembly 2 is activated, pushing the hydraulic rod 21, which in turn pushes the push rod 23 and the push plate 24, to push the metal material in both directions. Simultaneously, the stretching motor 1 continues to drive the chain drive, achieving continuous stretching and cold drawing of the metal material.

[0030] See also Figure 4 When cold drawing high-hardness metals, the pushing component 2 can be installed on the driving chain 8 for use. When installing, it should be noted that the cold drawing die should be placed between the clamp 10 and the pushing component 2. When cold drawing, the hydraulic pushing rod 21 on the pushing component 2 cooperates with the pushing rod 23 and the pushing plate 24 to push the cold-drawn metal end, and the cold-drawn metal at the other end is clamped by the clamp 10. As the driving chain 8 moves, the clamp 10 is driven to cold-draw the metal, which increases the cold drawing efficiency of hard metals and makes the force on the cold-drawn metal more uniform.

[0031] The working principle of this utility model is as follows: when using this device, it is necessary to install the device at the corresponding working position of the cold drawing machine and install the push assembly 2 at the corresponding height of the corresponding position (this is well known to those skilled in the art). After the stretching motor 1 is started, its output end drives the fixedly connected rotating shaft 11 to rotate. The end of the rotating shaft 11 away from the stretching motor 1 is fixedly connected to the driving sprocket 5, so that the driving sprocket 5 rotates with the rotating shaft 11.

[0032] The driving sprocket 5 is connected to the driven sprocket 7 via a drive chain 8. A driven shaft 6 is fixedly connected to the center of the driven sprocket 7. The outer walls of the driven shaft 6 are fixedly connected to bearing seats to ensure the stable rotation of the driven sprocket 7. When the driving sprocket 5 rotates, the driven sprocket 7 is rotated by the drive chain 8, forming a chain drive.

[0033] The top of the driving chain 8 is fixedly connected with a stretching car 9, and the stretching car 9 moves with the movement of the driving chain 8. The top of the stretching car 9 is fixedly connected with a clamp 10, and the clamp 10 is used to clamp the metal material to be cold-drawn.

[0034] While the driving sprocket 5 and the driven sprocket 7 provide chain drive, the pushing assembly 2 also contributes to the operation. The pushing assembly 2 includes a hydraulic push rod 21. The output end of the hydraulic push rod 21 is positioned toward one end of the driven sprocket 7 and is fixedly connected to a push rod 23. The end of the push rod 23, remote from the hydraulic push rod 21, is detachably connected to a push plate 24 via a flange. The installation height of the push plate 24 is aligned with the installation height of the clamp 10.

[0035] When bidirectional pushing is required, the stretching motor 1 drives the chain drive system, causing the stretching carriage 9 and clamp 10 to move in one direction, gripping the metal material for stretching. Simultaneously, the hydraulic rod 21 extends, applying opposing pushing forces to the metal material via the push rod 23 and push plate 24, achieving bidirectional pushing. This bidirectional pushing mechanism applies pushing force more evenly, improving the cold drawing effect.

[0036] The driving sprocket 5 is fixedly connected to the center of one end away from the stretching motor 1 with a driving shaft 4. The outer wall of the driving shaft 4 away from the driving sprocket 5 is also fixedly connected to a bearing seat to ensure the stable rotation of the driving sprocket 5. In addition, the outer wall of the stretching motor 1 is also fixedly connected to a fixing ring 3 for fixing the position of the stretching motor 1.

[0037] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
