[0002] Hydraulic cold drawing machines are key equipment in the metal processing field, mainly used for cold stretching of metal tubes and profiles to improve the dimensional accuracy and surface finish of workpieces, while also enhancing the strength and hardness of materials. They are widely used in industries such as machinery manufacturing, chemical engineering, and construction, meeting the production needs of various precision metal products. During operation, hydraulic cold drawing machines require support structures.

[0003] Utility model patent CN222535903U discloses a hydraulic cold drawing machine for copper busbar production, belonging to the field of copper busbar production equipment. It includes a support mechanism on which the cold drawing machine body is mounted. A feeding mechanism is located on the front top of the support mechanism, and a guiding mechanism is installed in the middle of the top of the support mechanism. A positioning mechanism is located within the guiding mechanism. The guiding mechanism includes a mounting platform with two guide rollers rotatably mounted inside. A pull-out frame is slidably connected within the mounting platform. The beneficial effects are: by setting up the guiding and positioning mechanisms, the copper coil diameter decreases during copper busbar production, causing changes in the conveying direction and affecting the forming effect. By setting the guide rollers and positioning blocks, the copper coil is guided, ensuring that the mold and the two guide rollers are always aligned. Furthermore, the guide rollers provide good guidance, guaranteeing the cold drawing effect and improving the quality of copper busbar production.

[0004] In the aforementioned prior art, during the use of the cold drawing machine, it is inconvenient to adjust the support height and to buffer the working process. Therefore, improvements are needed. Utility Model Content

Guide blocks 82 are slidably connected to the fixed seat 2. A guide groove 83 is provided on the inner side wall of the fixed seat 2. The guide blocks 82 are slidably connected inside the guide groove 83. The guide groove 83 is designed so that the guide blocks 82 can slide along it. A first spring 84 is provided on the outer side of the connecting rod 6. One end of the first spring 84 is fixedly connected to the slide block 3, and the other end of the first spring 84 is fixedly connected to the slider 81. The connection is achieved by designing a first spring 84, which allows the force of the first spring 84 to act on the slider 81. A positive and negative screw 85 is fixedly installed on the left end of the output end of the motor 7. Two symmetrically distributed connecting rods 86 are connected to the outer side of the positive and negative screw 85 by threads. The connecting rods 86 are slidably connected to the fixed base 2. A through groove 87 is opened inside the fixed base 2. The connecting rod 86 is slidably connected inside the through groove 87. By designing the through groove 87, the connecting rod 86 can slide along the through groove 87. The connecting rod 86 is fixedly connected to one of the sliders 81. An adjustment mechanism 8 is designed to facilitate the adjustment of the height of the support plate 5.

[0020] Please see Figure 1 , Figure 2 , Figure 4 The buffer mechanism 9 includes a guide rod 91. The lower end of the support plate 5 is fixedly connected to the guide rod 91. A guide sleeve 92 is slidably sleeved on the outer side of the guide rod 91. The guide sleeve 92 is fixedly connected to the base plate 1. An air valve 93 is provided on the guide sleeve 92. A second sealing ring 97 is slidably sleeved on the outer side of the guide rod 91. The second sealing ring 97 is fixedly connected to the guide sleeve 92.

One end of the second spring 96 is fixedly connected to the support block 94. The other end of the second spring 96 is fixedly connected to the guide sleeve 92. By designing the second spring 96, the force of the second spring 96 can act on the support block 94. By designing the buffer mechanism 9, the working process of the cold drawing machine can be damped and buffered.

[0021] The specific implementation process of this utility model is as follows: In use, a suitable mounting hole groove is opened on the support plate 5 for installation and use with the cold drawing machine. When it is necessary to adjust the operating height of the cold drawing machine, the motor 7 is started. The output end of the motor 7 drives the positive and negative screws 85 to rotate, causing the connecting rod 86 to perform threaded movement. The connecting rod 86 slides along the fixed seat 2, and at the same time, the connecting rod 86 drives the slider 81 to move. The slider 81 drives the connecting rod 6 and the first spring 84 to move. The first spring 84 pushes the slide 3 to move horizontally. The movement of the slide 3 can realize the deflection of the hinge rod 4, and the hinge rod 4 will push the support plate 5 to move vertically, so as to facilitate flexible adjustment of the operating height of the support.

[0022] When the cold drawing machine vibrates during operation, the vibration force is transmitted to the support plate 5. The support plate 5 moves down and pushes the hinge rod 4 to deflect. The hinge rod 4 can push the slide 3 to slide along the connecting rod 6 and compress the first spring 84. Under the elastic action of the first spring 84, a reverse thrust is given to the slide 3, which can buffer and dampen the vibration force. When the support plate 5 moves down, it will also drive the guide rod 91 to slide along the guide sleeve 92. The guide rod 91 simultaneously drives the support block 94 to move down and press down the second spring 96. Under the elastic action of the second spring 96, the vibration force can be further buffered, which can improve the damping effect. If the spring rebound force affects the buffering, the support block 94 will move up along the guide sleeve 92. The support block 94 can compress the nitrogen gas stored inside the guide sleeve 92, which will provide a certain resistance to the upward movement of the support block 94. This can unload and buffer the rebound force during vibration, and avoid the spring rebound force affecting the damping stability.
