Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe cold drawing equipment, and more specifically, it relates to a support device for a stainless steel pipe cold drawing machine. Background Technology

[0002] During the cold drawing process of stainless steel pipes, it is necessary to provide stable support and positioning for the stainless steel pipes to ensure the accuracy of the cold drawing process.

[0003] In the prior art, such as the "Support Device for a Cold Drawing Machine for Stainless Steel Pipes" disclosed in Chinese Patent Publication (Announcement) No. CN214767889U, it includes a support frame, which includes a base for connecting to the bottom plate of a trolley and a vertical rod fixedly connected to the base. The top of the vertical rod is connected to a support assembly for providing support to the steel pipe. The support assembly includes a lower support block fixedly connected to the top of the vertical rod and an upper pressure block located above the lower support block. A connector is connected between the lower support block and the upper pressure block.

[0004] While the aforementioned "support device for stainless steel pipe cold drawing machine" has solved the support and limiting problems during cold drawing of steel pipes to some extent, it still has the following shortcomings: 1. The vertical rod of the support device uses an outer sleeve and an inner rod to cooperate, and the locking rod is inserted into the locking hole to achieve telescopic extension. Since the locking holes are spaced along the length of the inner rod with a fixed spacing, only gear-type adjustment can be achieved. This means that when adapting to steel pipe specifications, if the required height is between two locking holes, it cannot be precisely adjusted and the existing gear must be used, affecting the support adaptability to the steel pipe, and the adjustment process is cumbersome and laborious; 2. The sides of the upper pressure block and the lower support block are both concave arc surfaces. Although they can play a certain supporting and limiting role for the steel pipe, the size of the arc groove is relatively fixed. When facing stainless steel pipes with different outer diameters, the arc groove and the surface of the steel pipe are difficult to fit completely. For pipes with large diameter differences, either there is a gap leading to unstable support, or the pipe is damaged due to excessive compression. In practice, it can only adapt to a single or a few sizes of pipes, which is difficult to meet diverse production needs. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3As shown, a support device for a stainless steel pipe cold drawing machine according to an embodiment of the present invention includes a base 1, a lifting mechanism 2 fixedly mounted on the top surface of the base 1, a bearing platform 20 on the top surface of the lifting mechanism 2, a support mechanism 3 for providing support for the steel pipe fixedly mounted on the top surface of the bearing platform 20, the support mechanism 3 including a support seat 30 fixedly mounted on the top surface of the bearing platform 20, two side plates 31 correspondingly formed on the top surface of the support seat 30 in the front-back direction, the top surface of the two side plates 31 are both formed with a first V-shaped groove 32, and an installation interval is formed between the two side plates 31, a stand 33 is fixedly mounted on the top surface of the support seat 30 within the installation interval, a pressure block 34 is slidably arranged on the stand 33 and the pressure block 34 is formed with a second V-shaped groove 35.

[0020] In use, a complete support system is constructed by setting up a base 1, a lifting mechanism 2, a bearing platform 20, and a support mechanism 3. The base 1 serves as the basic component, providing a stable installation foundation. The lifting mechanism 2 can flexibly adjust the height of the bearing platform 20 according to actual production needs, thereby adapting to the support height requirements of different cold drawing processes. The bearing platform 20 is used to support the support mechanism 3 and the stainless steel pipe. In the support mechanism 3, the first V-shaped groove 32 on the two side upright plates 31 and the second V-shaped groove 35 of the pressure block 34 cooperate with each other to form a stable V-shaped clamping structure. This structure can significantly improve the support stability of the stainless steel pipe. At the same time, the sliding setting of the pressure block 34 allows the support device to adapt to stainless steel pipes of different diameters, greatly improving the versatility and applicability of the device and effectively solving the problem of poor adaptability of support devices in the prior art.

[0021] The lifting mechanism 2 includes a mounting base 21 fixedly connected to the base 1. The mounting base 21 is connected to two scissor arm assemblies 22. The scissor arm assembly 22 is composed of two connecting rods 23 that are hinged to each other. The lower end of the scissor arm assembly 22 is hinged to the mounting base 21 and the upper end is hinged to the bearing platform 20.

[0022] In use, the lifting mechanism 2 adopts a connection structure between the mounting base 21 and the scissor arm assembly 22. The scissor arm assembly 22 consists of two hinged connecting rods 23, which are respectively hinged to the mounting base 21 and the bearing platform 20. Compared with the traditional fixed support method, this structure forms a stable and flexibly adjustable scissor lifting base. In practical applications, the hinged design of the scissor arm assembly 22 allows the bearing platform 20 to rise or fall smoothly within a certain range, thereby meeting the diverse needs of different specifications of pipe fittings and different cold drawing processes for support height. This effectively improves the versatility and flexibility of the device and overcomes the shortcomings of inconvenient height adjustment of the support device in the prior art.

[0023] The two connecting rods 23 are hinged together by pivots 24. Both pivots 24 are formed with first nut sleeves 25. A first adjusting screw 26 is passed through the two first nut sleeves 25. The first adjusting screw 26 has two threaded sections 27 with opposite directions of rotation. The two threaded sections 27 are respectively adapted to the two first nut sleeves 25.

[0024] In use, a pivot 24, a first nut sleeve 25, and a first adjusting screw 26 are set between the connecting rods 23 of the scissor arm assembly 22. The first adjusting screw 26 has two threaded sections 27 with opposite directions of rotation that are adapted to the first nut sleeve 25. This unique design allows for precise control of the relative movement of the two scissor arm assemblies 22 by utilizing the thread transmission principle when rotating the first adjusting screw 26. By precisely adjusting the included angle of the scissor arm assemblies 22, the lifting height of the bearing platform 20 can be precisely controlled. Compared with traditional lifting adjustment methods, this structure greatly improves the accuracy and stability of lifting adjustment, and can more accurately adapt to the support height required for cold drawing of stainless steel pipes of different specifications, ensuring stable support of the stainless steel pipes during the cold drawing process.

[0025] One end of the first adjusting screw 26 is connected to a rocker arm 28. The rocker arm 28 is used to drive the first adjusting screw 26 to rotate. The first adjusting screw 26 drives the two scissor arm assemblies 22 to move relative to each other, thereby changing the included angle of the scissor arm assemblies 22 and realizing the lifting action of the bearing platform 20.

[0026] In use, the rocker arm 28 connected to one end of the first adjusting screw 26 provides operators with a convenient driving method. By manually rocking the rocker arm 28, the first adjusting screw 26 can be easily rotated, thereby realizing the lifting and lowering of the support platform 20. This manual operation method is not only simple and labor-saving, reducing the difficulty of operation, but also eliminates the need for a complex power system, reducing equipment costs and failure risks. It is very suitable for the simple and efficient operation requirements of the cold drawing machine site. Operators can adjust the height of the support platform 20 in real time and flexibly according to the actual situation, enhancing the adaptability and operability of the device in actual production.

[0027] The support frame 33 includes two columns 4, and a top plate 40 is installed on the top surface of the two columns 4. A second nut sleeve 41 is fixed in the center of the top plate 40. A second adjusting screw 42 is provided inside the second nut sleeve 41. The lower end of the second adjusting screw 42 is rotatably connected to the pressure block 34. The left and right sides of the pressure block 34 are correspondingly formed with guide grooves 36 that are adapted to the two columns 4.

[0028] In use, the support frame 33 adopts a combination structure of two columns 4, a top plate 40, a second nut sleeve 41, a second adjusting screw 42, and a pressure block 34. The pressure block 34 is equipped with a guide groove 36 that cooperates with the columns 4. By rotating the second adjusting screw 42, the pressure block 34 can be driven to slide stably up and down along the columns 4 through its threaded connection with the second nut sleeve 41. The matching design of the guide groove 36 and the columns 4 ensures that the pressure block 34 is accurate in direction during sliding and will not deviate or shake. This structure allows the position of the pressure block 34 to be flexibly adjusted according to the diameter of the stainless steel pipe, thereby providing stable and reliable support for pipe fittings of different diameters and further improving the device's adaptability and support stability for stainless steel pipes of different specifications.

[0029] The upper end of the second adjusting screw 42 is connected to a rotary control lever 43.

[0030] In use, the rotary control lever 43 connected to the upper end of the second adjusting screw 42 further optimizes the operating experience compared to directly rotating the second adjusting screw 42. By turning the rotary control lever 43, the operator can more easily and quickly drive the second adjusting screw 42 to rotate, thereby realizing the lifting and lowering adjustment of the pressure block 34. This design simplifies the operation process, reduces the difficulty of operation, and improves the adjustment efficiency. Especially in production scenarios where the position of the pressure block 34 needs to be frequently adjusted to adapt to stainless steel pipes of different diameters, the advantages are more obvious, making the use of the device more convenient and efficient.

[0031] A fastening nut 5 is fixedly installed on the side plate 31, and fastening holes that are compatible with the fastening nut 5 are formed at the lower ends of the two columns 4.

[0032] During use, the fastening nut 5 on the side plate 31 engages with the fastening hole at the lower end of the column 4 (the fastening hole is a conventional through hole structure, not shown in the figure). Through the connection of nuts and bolts, the upright 33 can be quickly disassembled and fixed. During the maintenance and repair of the device, the operator can easily disassemble the upright 33 for inspection, repair or replacement of parts, which greatly improves maintenance efficiency. This connection method can ensure the stability of the upright 33 after installation, and avoid the impact of the upright 33 shaking on the support stability and cold drawing accuracy of the pipe fittings during the cold drawing process of stainless steel pipes, thus ensuring the long-term stable and reliable operation of the device.

[0033] Several balls 37 are movably embedded in the inner groove surfaces of the first V-groove 32 and the second V-groove 35. The balls 37 are used to form a rolling fit structure between the groove surface and the pipe to be supported.

[0034] In use, ball bearings 37 are embedded in the inner groove surfaces of the first V-groove 32 and the second V-groove 35 to form a rolling fit structure. This changes the rigid contact between the pipe and the groove surface in the traditional support device. When the stainless steel pipe moves within the support device, the rolling of the ball bearings 37 greatly reduces the friction between the pipe and the groove surface. On the one hand, this effectively protects the surface quality of the stainless steel pipe, preventing it from being scratched or worn during cold drawing, thus ensuring the appearance and performance of the product. On the other hand, the reduced friction makes the movement of the pipe within the support device smoother, reducing resistance during the cold drawing process, which helps to improve the efficiency of cold drawing, while also reducing equipment wear and extending the service life of the support device.

[0035] The specific working process of this utility model is as follows: First, the base 1 is fixedly installed to provide a stable foundation for the entire device. Then, the operator can drive the first adjusting screw 26 to rotate by shaking the rocker arm 28. By utilizing the engagement of its oppositely helical thread section 27 with the first nut sleeve 25, the included angle of the scissor arm assembly 22 can be precisely adjusted to achieve flexible adjustment of the height of the bearing platform 20, so as to adapt to the height requirements of different cold drawing processes and pipe fittings. Next, according to the diameter of the stainless steel pipe, the second adjusting screw 42 is rotated by turning the control lever 43, which drives the pressure block 34 to slide stably along the guide groove 36 on the column 4, so that the distance between the first V-groove 32 and the second V-groove 35 is adapted to the pipe fitting. After adjustment, the stainless steel tube is placed on the first V-groove 32, and the pressure block 34 descends to form a V-shaped clamping structure for stable support. During the cold drawing process, the ball bearings 37 in the V-groove form a rolling fit with the tube, reducing friction, protecting the surface of the tube, and reducing equipment wear, ensuring smooth movement of the stainless steel tube. In addition, when maintenance of the upright frame 33 is required, the upright frame 33 can be quickly disassembled and assembled by means of bolt connection through the fastening nut 5 and the fastening hole, which facilitates inspection, maintenance or replacement of parts and ensures long-term stable operation of the device.
