[0046] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0047] like Figures 1 to 7As shown, according to an embodiment of the present application, a new type of cold drawing machine trolley is proposed, including: a moving body 100; a drawing seat 200, which is detachably mounted on the above-mentioned moving body 100; a cone sleeve 300, which is arranged at one end of the above-mentioned drawing seat 200 away from the moving body 100 along the moving direction of the above-mentioned moving body 100, and is used to support the tube body, and the inner surface of the above-mentioned cone sleeve 300 is a cone; a clamping assembly 400, which is arranged between the above-mentioned moving body 100 and the drawing seat 200, and the clamping end of the above-mentioned clamping assembly 400 is slidably mounted on the inner surface of the above-mentioned cone sleeve 300 along the axis of the above-mentioned cone sleeve 300, and is used to clamp the tube body in the cone sleeve 300; a hook plate 500, which is fixedly arranged on the inner surface of the above-mentioned cone sleeve 300, and is used to prevent the tube body in the above-mentioned cone sleeve 300 from moving toward the direction of the above-mentioned moving body 100.

[0048] The new cold drawing machine trolley provided in the embodiment of the present application includes a moving body 100, a drawing seat 200, a cone sleeve 300, a clamping assembly 400 and a hook plate 500, wherein the drawing seat 200 and the moving body 100 are detachably mounted together by bolts, the inner surface of the cone sleeve 300 is also a cone, and the hook plate 500 is fixedly mounted on the inner surface of the cone sleeve 300. When the new cold drawing machine trolley is in use, the cone sleeve 300 is used to support the pipe body. When one end of the pipe body is in the cone sleeve 300, the pipe body in the cone sleeve 300 is clamped by the clamping assembly 400. When the work is completed, the new cold drawing machine trolley needs to be separated from the pipe body, and one end of the pipe body is loosened by the clamping assembly 400, thereby realizing the separation of the pipe body and the new cold drawing machine trolley.

[0049] Among them, the hook plate 500 can be set on the side of the cone sleeve 300 close to the movable body 100. The hook plate 500 can prevent the pipe from continuing to move in the cone sleeve 300 toward the movable body. After the work is completed, when the new cold drawing machine trolley needs to be separated from the pipe body, the clamping assembly 400 has too much clamping pressure. When the clamping assembly 400 is separated from the pipe, the pipe continues to move deeper into the cone sleeve 300 with the clamping assembly 400. When the pipe continues to move deeper into the interior of the cone sleeve 300, the hook plate 500 can prevent the pipe from continuing to move into the interior of the cone sleeve 300, that is, moving in the direction of the movable body 100, so that when the clamping mechanism is opened, the pipe is easily separated from the new cold drawing machine trolley, thereby reducing the operator's work intensity and improving work efficiency.

[0050] Exemplarily, a tail hook 600 is provided at one end of the mobile body 100 away from the drawing seat 200 for connecting with external equipment, and a vertical guide roller 700 is provided at the bottom of the mobile body 100 for assisting the movement of the mobile body 100.

[0051] like Figures 1 to 7As shown, in some examples, the clamping assembly 400 includes: a hydraulic cylinder 410, which is arranged on the mobile body 100 or the drawing seat 200; an outer clamp 420, which is slidably installed on the inner surface of the cone sleeve 300 along the axis of the cone sleeve 300; and a connecting assembly 430, which is arranged between the output end of the hydraulic cylinder 410 and the outer clamp 420, and is used to enable the hydraulic cylinder 410 to drive the outer clamp 420 to move on the inner surface of the cone sleeve 300.

[0052] In this technical solution, the clamping assembly 400 includes a hydraulic cylinder 410 mounted on the mobile body 100 or the drawing base 200. The hydraulic cylinder 410 serves as a power source, providing stable and powerful driving force for the clamping assembly 400. When mounted on the mobile body 100, the hydraulic cylinder 410 fully leverages the structural stability of the mobile body 100, ensuring that the hydraulic cylinder 410 does not shift due to external forces during operation. When mounted on the drawing base 200, however, the hydraulic cylinder 410 more directly transmits power to the outer clamp 420, improving clamping efficiency. The outer clamp 420 is slidably mounted on the inner surface of the taper sleeve 300 along the axis of the taper sleeve 300. Sliding along the axis of the taper sleeve 300, the outer clamp 420 accurately clamps the pipe within the taper sleeve 300. This sliding mounting ensures the stability and accuracy of the outer clamp 420 during operation, ensuring that the clamping force is evenly applied to the pipe. The connecting assembly 430 is arranged between the output end of the hydraulic cylinder 410 and the outer clamp 420, and is used to enable the above-mentioned hydraulic cylinder 410 to drive the outer clamp 420 to move on the inner surface of the above-mentioned cone sleeve 300. The connecting assembly 430 transmits the powerful power generated by the hydraulic cylinder 410 to the outer clamp 420, so that the outer clamp 420 can move precisely on the inner surface of the cone sleeve 300.

[0053] During the use of the new cold drawing machine trolley, when the pipe body needs to be clamped, the hydraulic cylinder 410 is started, and the outer clamp 420 is driven to move toward the pipe body along the axis of the cone sleeve 300 through the connecting component 430 until the outer clamp 420 tightly clamps the pipe body; when the work is completed and the pipe body needs to be released, the hydraulic cylinder 410 reverses and drives the outer clamp 420 away from the pipe body through the connecting component 430, thereby realizing the separation of the pipe body and the new cold drawing machine trolley.

[0054] like Figures 1 to 7 As shown, in some examples, the connecting assembly 430 includes: a distributor 431 coaxially fixedly mounted on the output end of the hydraulic cylinder 410 ; and a connecting rod 432 disposed between the distributor 431 and the outer clamp 420 .

[0055] In this technical solution, the connecting assembly 430 includes a distributor 431 and a connecting rod 432. The distributor 431 is coaxially fixedly installed on the output end of the hydraulic cylinder 410. The distributor 431 is coaxially fixedly installed with the output end of the hydraulic cylinder 410, ensuring the accuracy and stability of power transmission. The distributor 431 can effectively and reasonably distribute the power generated by the hydraulic cylinder 410, so that the power can be evenly transmitted to subsequent components. At the same time, the fixed installation method ensures that the distributor 431 will not be displaced or loosened due to external force during operation, thereby ensuring the reliability of the entire system.

[0056] The connecting rod 432 is arranged between the distributor 431 and the outer clamp 420. During operation, the distributor 431 transmits the power of the hydraulic cylinder 410 to the connecting rod 432, and the connecting rod 432 transmits the power to the outer clamp 420, so that the outer clamp 420 can move accurately on the inner surface of the cone sleeve 300 to achieve clamping and releasing operations on the pipe body.

[0057] During the actual operation of the new cold drawing machine trolley, when the hydraulic cylinder 410 is started, the power at the output end is first transmitted to the distributor 431. After the distributor 431 reasonably distributes the power, the power is transmitted to the outer clamp 420 through the connecting rod 432. The outer clamp 420 is pushed by the connecting rod 432 and moves along the axis of the cone sleeve 300 toward the pipe body to clamp the pipe body. When the pipe body needs to be loosened, the hydraulic cylinder 410 reverses the action, and the power is transmitted to the outer clamp 420 through the distributor 431 and the connecting rod 432 in turn, so that the outer clamp is away from the pipe body, completing the separation operation of the pipe body and the new cold drawing machine trolley.

[0058] like Figures 1 to 7 As shown, in some examples, the clamping assembly 400 further includes: an inner core mold 440, which is detachably mounted on the distributor 431, and the inner core mold 440 is coaxially arranged with the cone sleeve 300, for allowing the tube body to be sleeved on the inner core mold 440.

[0059] In this technical solution, the clamping assembly 400 further includes an inner core mold 440 detachably mounted on the distributor 431. The detachable mounting method of the inner core mold 440 allows the inner core mold 440 to be replaced quickly and conveniently according to the requirements of tubes of different specifications during actual use. When tubes of different sizes need to be processed, the operator can quickly remove the old inner core mold 440 and install a new inner core mold 440 that matches the old tubes, thereby greatly improving the versatility and adaptability of the new cold drawing machine carriage.

[0060] When the cold drawing machine trolley of the existing equipment is in use, the size and shape of the tube head of the tube body need to be modified to adapt to the fixed connector of the existing cold drawing machine trolley. When the operation is completed, the tube head of the tube body needs to be cut and discarded. The inner core mold 400 of the present technical solution can be detachably mounted on the distributor 431, which greatly improves the versatility and adaptability of the new cold drawing machine trolley, thereby avoiding waste of pipes.

[0061] The inner core mold 440 is coaxially arranged with the cone sleeve 300, and is used to allow the tube body to be sleeved on the inner core mold 440. The coaxial arrangement ensures the stability and accuracy of the tube body during the clamping process. When the tube body is sleeved on the inner core mold 440, the inner core mold 440 provides a stable support and positioning function for the tube body. The inner core mold 440 can ensure that the tube body will not deviate or shake during the clamping and pulling process.

[0062] During the operation of the new cold drawing machine carriage, when a tube needs to be clamped and drawn, the tube is first placed on the inner core mold 440, and then the outer clamp 420 is driven by the hydraulic cylinder 410 to clamp the tube. During the clamping process, the inner core mold 440 and the outer clamp 420 cooperate with each other to ensure stable clamping of the tube.

[0063] like Figures 1 to 7 As shown, in some examples, the inner core mold 440 is a cone inner core mold.

[0064] In this technical solution, the inner core mold 440 is conical in shape, and its surface gradually tapers from one end to the other, matching the shape of the inner wall of the tube body. When the tube body is sleeved on the inner core mold 440, as the tube body goes deeper, the contact area between the tube body and the inner core mold 440 gradually increases, and the friction force also increases accordingly, thereby effectively preventing the tube body from sliding or deflecting during the drawing process.

[0065] In some examples, there are at least two outer clamps 420 .

[0066] In some examples, the cone sleeve 300 can be detachably mounted on the drawing seat 200 .

[0067] In this technical solution, there are at least two external clamps 420. When the number of external clamps 420 is two or more, the tube body can be clamped from different angles and positions, thereby greatly improving the stability and reliability of clamping. Each external clamp 420 bears a certain clamping force. Through reasonable distribution, the tube body can be subjected to more uniform force during the clamping process, avoiding deformation or damage of the tube body due to excessive local force. At the same time, the synergistic effect of multiple external clamps 420 can adapt to tube bodies of different sizes and shapes, increasing the versatility and applicability of the new cold drawing machine trolley.

[0068] In some examples, the cone sleeve 300 is detachably mounted on the drawing seat 200. This detachable mounting method greatly facilitates the use and maintenance of the cold drawing machine trolley. When the cone sleeve 300 needs to be replaced or repaired, it can be easily and quickly removed from the drawing seat 200 without having to disassemble the entire drawing seat 200, greatly saving time and labor costs. The detachable design also allows for replacement of cone sleeves 300 of different specifications and models according to different work requirements to accommodate pipes of different sizes and shapes, thereby improving the flexibility and adaptability of the cold drawing machine trolley. In addition, the detachable cone sleeve 300 is also easy to clean and maintain, which can extend the service life of the cone sleeve 300 and ensure the working efficiency and quality of the cold drawing machine trolley.

[0069] like Figures 1 to 7 As shown, in some examples, the hook plate 500 includes a fixing member 510 fixedly mounted on the inner surface of the cone sleeve 300; and a blocking member 520 disposed at one end of the fixing member 510 near the mobile body 100. In some examples, the gap between the blocking member 520 and the inner core mold 440 is less than the wall thickness of the tube. In some examples, there are at least two hook plates 500.

[0070] In this technical solution, the hook plate 500 includes a fixing part 510 and a blocking part 520. The fixing part 510 is fixedly installed on the inner surface of the cone sleeve 300, and the blocking part 520 is arranged at one end of the fixing part 510 close to the above-mentioned mobile body 100; the blocking part 520 can play a key blocking role in the process of the tube body entering the cone sleeve 300.

[0071] In some examples, the gap between the blocking member 520 and the inner core mold 440 is smaller than the wall thickness of the tube. When the tube is sleeved onto the inner core mold 440 and enters the cone sleeve 300, the tube can be blocked on the side of the blocking member 520 away from the mobile body 100 because the gap between the blocking member 520 and the inner core mold 440 is smaller than the wall thickness of the tube.

[0072] In some examples, the provision of multiple hook plates 500 can further improve the clamping stability of the tube body. When the tube body enters the cone sleeve 300, the multiple hook plates 500 simultaneously block the tube body, so that the tube body is subjected to uniform force in all directions.
