[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0035] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0036] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0037] This utility model provides a bidirectional pulling device, such as... Figures 1 to 3 As shown, it includes a mounting base 1, a fixing component 2, a moving component 3, and a drive mechanism 4.

[0038] In this embodiment, the mounting base 1 serves as the supporting foundation for the entire device, providing mounting positions for other components. In this embodiment, the pulling device also includes a base 5, on which a slide rail 51 is provided. The mounting base 1 is slidably mounted on the base 5 via the slide rail 51. In actual production, the position of the pulling device may need to be fine-tuned according to different processing requirements, material dimensions, or compatibility with other equipment. Through the slide rail 51, operators can easily push the mounting base 1 to slide on the base 5, quickly and accurately adjusting the position of the device without complex disassembly and reinstallation operations, effectively saving time and labor costs.

[0039] In other embodiments, the mounting base 1 can be automatically adjusted along the slide rail 51 by working in conjunction with drive components such as drive cylinders and motors, further saving time and labor costs.

[0040] It should be noted that in this embodiment, the drawing device only performs the function of clamping materials such as bars. The drawing device can be installed on a chain drawing machine, hydraulic drawing machine or other drawing machine via the base 5 to perform reciprocating motion.

[0041] In this embodiment, the movable part 3 has a horizontally symmetrical structure, and the fixed part 2 is fixed on the mounting base 1. It has two sets of symmetrical first clamping surfaces 21 for cooperating with the movable part 3 to clamp the material. The movable part 3 is rotatably mounted on the mounting base 1 and has two sets of symmetrical second clamping surfaces 31. The first clamping surfaces 21 and the second clamping surfaces 31 are arranged opposite to each other to form a clamping structure for clamping the material. An angled gap 311 is formed between the first clamping surfaces 21 and the second clamping surfaces 31. During the drawing process, the rod is clamped in the angled gap 311.

[0042] In this embodiment, a fixing pin 6 is also included. A fixing part 22 is provided on the fixing part 2, and an installation part 32 is provided on the movable part 3. The fixing part 22 and the installation part 32 are arranged in an overlapping manner. The fixing pin 6 passes through the fixing part 22 and the installation part 32. The movable part 3 rotates around the fixing pin 6. This rotating connection structure is simple and stable, providing a basis for adjusting the included angle gap 311.

[0043] In this embodiment, the adjustable range of the included angle gap 311 is 5°-30°, which can adapt to the clamping requirements of bars of different sizes.

[0044] In this embodiment, the movable part 3 is a fan-shaped structure with a central angle of 100-145°. The two sets of second clamping surfaces 31 are located on the radial edges of the two sides of the fan shape, which makes the movement trajectory of the second clamping surface 31 more reasonable and can better cooperate with the first clamping surface 21 to achieve uniform adjustment of the clamping angle gap 311. At the same time, it is also conducive to ensuring the uniform distribution of clamping force and improving the clamping quality.

[0045] In this embodiment, both the first clamping surface 21 and the second clamping surface 31 are provided with anti-slip textures 312, which can effectively increase the friction between the first clamping surface 21, the second clamping surface 31 and the rod, prevent slippage, and thus effectively improve the stability of the rod when it is drawn.

[0046] In this embodiment, the mounting base 1 is provided with a guide groove 11, and the bottom end face of the movable part 3 is provided with a limiting part 33 that is fitted and slidably engaged with the guide groove 11. The guide groove 11 has an arc-shaped structure, and the center of the guide groove 11 coincides with the axis of the fixed pin 6, which can effectively ensure the stability of the rotation of the movable part 3.

[0047] In this embodiment, the drive mechanism 4 includes a cylinder 41 and a transmission assembly 42. The cylinder 41 and the movable part 3 are movably connected to the transmission assembly 42. The transmission assembly 42 includes a connecting rod 421. The two ends of the connecting rod 421 are hinged to the movable part 3 and the piston rod of the cylinder 41, respectively, allowing the connecting rod 421 to rotate relative to the movable part 3 and the piston rod of the cylinder 41 within a certain angle range.

[0048] In this embodiment, the cylinder 41 has a telescopic action characteristic. When the piston rod of the cylinder 41 telescopically moves, the linear motion is transmitted to the movable part 3 through the connecting rod 421 hinged to it. Since the connecting rod 421 is hinged to the movable part 3, the movable part 3 will rotate around its rotation center under the action of force, thereby realizing the conversion of the linear motion of the cylinder 41 into the rotational motion of the movable part 3. The smooth and precise rotation of the movable part 3 can ensure the uniform adjustment of the included angle gap, making the clamping force distribution between the first clamping surface 21 and the second clamping surface 31 and the bar more uniform, which can effectively improve the clamping stability, reduce the slippage and shaking of the bar during the drawing process, and thus improve the quality of the drawn product.

[0049] In this embodiment, the drive mechanism 4 includes two sets, which are symmetrically distributed on both sides of the horizontal central axis of the rotation center of the movable part 3. The two sets of drive mechanisms 4 are respectively linked to the front and rear sides of the movable part 3 so that the extension and retraction of the cylinder 41 can drive the movable part 3 to rotate and adjust the size of the included angle gap 311 between the front and rear sides.

[0050] In this embodiment, cylinder 41 is a double-acting cylinder 41, which is controlled by a solenoid valve to switch directions. When the solenoid valve of one cylinder 41 is energized to extend its piston rod, the solenoid valve of the other cylinder 41 is de-energized to retract its piston rod, ensuring that the moving part 3 rotates smoothly and steadily, thus improving the operational reliability of the equipment.

[0051] In this embodiment, the extension and retraction stroke of cylinder 41 is linearly proportional to the rotation angle of movable component 3; for every 50mm extension and retraction of cylinder 41, movable component 3 rotates 5°. In other embodiments, the length ratio between connecting rod 421 and rocker arm 422 can be adjusted according to actual usage to change this linear proportional relationship and meet usage requirements.

[0052] In operation, one extruder can be precisely installed at each end of the workshop production area. Simultaneously, the positions of two drawing devices should be strategically planned within the workshop, corresponding to the extruders at both ends, forming a complete bidirectional drawing production line layout. One drawing device clamps the bar extruded from one end of the workshop, while the other clamps the bar extruded from the other end. The two devices pull the bar in opposite directions. When the bar is pulled to the position of the extruder at the other end, the drawing device releases the bar and uses its other clamping surface to hold a new extruded bar, continuing the opposite drawing operation. This cycle repeats continuously, achieving bidirectional drawing production and effectively improving production efficiency.

[0053] The present invention provides a bidirectional drawing device that achieves bidirectional drawing by setting two sets of drive mechanisms 4 respectively linked to the front and rear sides of the movable part 3, thereby realizing bidirectional drawing operation. The drawing direction can be flexibly adjusted according to actual production needs, which can effectively improve production efficiency and equipment versatility, realize reliable clamping of bar stock, flexible position adjustment and automated drive, and adapt to various processing needs and material types, effectively improving production efficiency and product quality, and reducing operation difficulty and cost.
