Description

Technical Field

[0001] This utility model relates to the field of wire drawing technology, specifically to a stainless steel tube wire drawing device. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as in mechanical structural components. Additionally, it is lighter in weight while maintaining the same bending and torsional strength, making it widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware.

[0003] Stainless steel pipe wire drawing is a metal processing technique and one of the most popular surface treatment technologies in the stainless steel and aluminum products industry today. The wire drawing effect of stainless steel products is achieved by grinding the surface of the stainless steel pipe raw material with a wire drawing machine to form lines, thereby achieving the wire drawing effect. Since the matte surface formed after wire drawing of stainless steel pipe is more wear-resistant than the ordinary bright surface, the application of wire drawing is becoming more and more widespread in the field of stainless steel pipe processing.

[0004] Existing methods for drawing stainless steel pipes are inconvenient due to the varying lengths of the pipes, making batch processing and unloading difficult. Therefore, these methods do not meet current requirements. To address this, we propose a stainless steel pipe drawing device. Utility Model Content

[0023] Please see Figures 1 to 3 This utility model provides an embodiment of a stainless steel pipe drawing device, including a guide slide plate 3. Two pipe end clamping mechanisms 7 are installed on the upper end surface of the guide slide plate 3. A synchronous drawing mechanism 8 is installed between the two pipe end clamping mechanisms 7. The two pipe end clamping mechanisms 7 are symmetrically installed with respect to the synchronous drawing mechanism 8. The pipe end clamping mechanism 7 includes a clamping slide 701. Multiple guide sleeves 702 are installed on the inner side of the clamping slide 701. A first electric push rod 703 is fixedly installed at one end of the guide sleeve 702. A conical clamping rod 704 is slidably connected to the inner side of the guide sleeve 702. The multiple guide sleeves 702 are linearly arranged along the side of the clamping slide 701. The output end of the first electric push rod 703 passes through the guide sleeve 702 and is fixedly connected to the conical clamping rod 704. The guide sleeve 702 and the conical clamping rod 704 are coaxial. By fine-tuning the conical clamping rod 704, the stainless steel pipe can be precisely clamped, keeping the stainless steel pipe centered and stable.

[0024] Please see Figure 3 and Figure 4 The synchronous wire drawing mechanism 8 includes a movable mounting frame 801. A connecting frame 802 is fixedly installed in the middle of the rear end face of the movable mounting frame 801. A second drive motor 803 is fixedly installed at one end of the connecting frame 802. A drive wheel is fixedly provided at the output end of the second drive motor 803. The drive wheel is in close contact with the inner wall of the mounting frame 2, so that the second drive motor 803 drives the drive wheel to rotate under the support of the connecting frame 802. Then, while the drive wheel rolls on the inner wall of the mounting frame 2, the connecting frame 802 and the movable mounting frame 801 synchronously drive multiple first wire drawing arc plates 806 and second wire drawing arc plates 807 to reciprocate along the axis of the stainless steel tube.

[0025] The rear end face of the movable mounting bracket 801 is slidably connected to the transmission plate 804 inside the connecting bracket 802. A second electric push rod 805 is installed at the bottom end of the transmission plate 804. The second electric push rod 805 is fixedly connected to the movable mounting bracket 801, and the output end of the second electric push rod 805 is fixedly connected to the bottom end of the transmission plate 804. A plurality of second wire drawing arc plates 807 are installed on the front end face of the transmission plate 804. The rear ends of the plurality of second wire drawing arc plates 807 all penetrate the movable mounting bracket 801 and are fixedly connected to the transmission plate 804. A first... A first wire drawing arc plate 806 and a second wire drawing arc plate 807 are in contact with the upper end surface of the first wire drawing arc plate 806. A movable mounting bracket 801 is fixedly connected to multiple first wire drawing arc plates 806. A wire drawing hole is formed between the first wire drawing arc plate 806 and the second wire drawing arc plate 807. The wire drawing hole is coaxial with the cone head clamping rod 704. A second electric push rod 805 drives multiple second wire drawing arc plates 807 to move down and contact the upper end surface of the first wire drawing arc plate 806 through a transmission plate 804, thereby achieving the covering of the stainless steel tube by the first wire drawing arc plate 806 and the second wire drawing arc plate 807.

[0026] Please see Figures 1 to 3 A mounting frame 2 is fixedly installed on the outer side of the guide slide plate 3. A support base 1 is fixedly installed on the lower end face of the mounting frame 2. Two guide posts 5 are fixedly installed on the inner side of the upper end of the mounting frame 2. A transmission screw 6 is installed between the two guide posts 5. A first transmission motor 4 is fixedly installed on the upper part of one end of the mounting frame 2. The output end of the first transmission motor 4 passes through the mounting frame 2 and is connected to the transmission screw 6 through a coupling. The upper ends of the movable mounting bracket 801 and the two clamping slides 701 are slidably connected to the two guide posts 5. The two ends of the transmission screw 6 are provided with external threads with opposite directions of rotation. The two ends of the transmission screw 6 are connected to the two clamping slides 701 by threads. The bottom ends of the movable mounting bracket 801 and the two clamping slides 701 are slidably connected to the guide slide plate 3. The first transmission motor 4 drives the two clamping slides 701 to move towards each other along the axis of the guide column 5 through the transmission screw 6. Then, the clamping slides 701 drive the cone clamping rod 704 to perform preliminary positioning of the two ends of the stainless steel tube through the guide sleeve 702 and the first electric push rod 703.

[0027] In summary, when drawing stainless steel tubes, multiple stainless steel tubes of the same length are placed on the upper surfaces of multiple first drawing arc plates 806. The power is turned on, and the first drive motor 4 is started. Under the support of the mounting frame 2, the first drive motor 4 drives two clamping slides 701 to move towards each other along the axis of the guide column 5 through the drive screw 6. Then, the clamping slides 701 drive the conical clamping rod 704 to initially position the two ends of the stainless steel tube through the guide sleeve 702 and the first electric push rod 703. Then, the first electric push rod 703 is started, and under the support of the guide sleeve 702, the first electric push rod 703 drives the conical clamping rod 704 to slide axially relative to the guide sleeve 702. Then, by fine-tuning the conical clamping rod 704, the stainless steel tube is precisely clamped, keeping the stainless steel tube centered and stable.

[0028] Then, the second electric push rod 805 is activated, which, under the support of the movable mounting frame 801, synchronously drives multiple second wire drawing arc plates 807 to move downwards through the transmission plate 804 and come into contact with the upper end face of the first wire drawing arc plate 806. This allows the wire drawing holes formed by the first wire drawing arc plate 806 and the second wire drawing arc plate 807 to cover the stainless steel tube. The second drive motor 803 is then activated, which, under the support of the connecting frame 802, drives the drive wheel to rotate. As the drive wheel rolls on the inner wall of the mounting frame 2, it simultaneously drives multiple first wire drawing arc plates 806 and second wire drawing arc plates 807 to slide back and forth along the axis of the stainless steel tube through the connecting frame 802 and the movable mounting frame 801. This allows the first wire drawing arc plates 806 and the second wire drawing arc plates 807 to perform wire drawing treatment on the surface of the stainless steel tube.
