[0034] A drawing device is a piece of equipment used in material processing, primarily for stretching metals or other materials through a die orifice to change their cross-sectional dimensions, extend their length, and improve their mechanical properties. Drawing devices are widely used in the production of materials such as metals, plastics, and glass, especially in the manufacture of products like steel wire, pipes, bars, and guide rails. However, current drawing devices suffer from low production efficiency and poor product stability.
[0035] Based on this, please refer to Figure 1 The drawing device 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems, and the drawing device 1000 can improve production efficiency and product stability. The production line with the drawing device 1000 also has the same functions as described above.
[0036] The production line provided in this embodiment includes heat treatment equipment, rolling equipment, and a drawing device 1000. The rolling equipment is used to hot roll the workpiece 2000 to produce a wire rod with an outer contour dimension close to that of the finished product. The heat treatment equipment can change the material properties of the workpiece 2000 to facilitate processing or ensure the properties of the finished product. The drawing device 1000 is used to plasticize the workpiece 2000 to produce the shape of the finished product. Of course, the production line may also include other equipment such as finishing equipment, depending on actual production needs and product precision requirements, and is not limited here.
[0037] Figure 1 This is a schematic diagram of the pulling device 1000 provided in an embodiment of this utility model. Figure 1As shown, the drawing device 1000 in this embodiment includes a drive assembly 100, a die assembly 200, a drawing assembly 300, and a first guide 400. The die assembly 200 is connected to the drive assembly 100; the drawing assembly 300 is arranged side-by-side with the die assembly 200 and is connected to the drive assembly 100; the first guide 400 is arranged side-by-side with the drawing assembly 300 and is close to the drawing assembly 300. The first guide 400 is used to ensure the straightness of the workpiece 2000 during the drawing process. The drive assembly 100 is used to drive the die assembly 200 to perform hole processing on the workpiece 2000 that has passed through the die assembly 200. The drive assembly 100 is used to drive the drawing assembly 300 to deform the workpiece 2000. By setting the first guide 400, the workpiece 2000 can be prevented from shifting or swaying during the force process, thereby improving the straightness of the workpiece 2000. By integrating drawing and die finishing, inter-process waiting and handling time can be reduced, as well as the operations of transferring and repositioning workpieces between different devices, thereby improving production efficiency, product stability, and product quality. It also saves floor space and reduces equipment and manpower investment. Using the die assembly 200 for finishing, the contact between the die assembly 200 and the workpiece 2000 is gentler, ensuring finishing effects without the use of cutting tools, thus avoiding frequent tool breakage and reducing production costs. In this embodiment, the drawing device 1000 is mainly used for processing guide rails; however, the drawing device 1000 can also be applied to processing other products, which is not limited here.
[0038] To simplify the number of drawing passes, reduce die investment, and avoid die breakage, please refer to [link / reference]. Figure 1 and combined Figure 2 , Figure 2This is a partial schematic diagram of the drawing device 1000 provided in an embodiment of the present invention. The drawing assembly 300 in this embodiment includes at least two sets of roller groups 310, each set of roller groups 310 being arranged at an angle to each other. That is, this embodiment adopts a roller die drawing processing method, where the roller groups 310 continuously apply gradually increasing compressive force to the workpiece to be processed, thereby deforming the workpiece 2000. Compared with traditional drawing methods, roller dies can reduce friction and apply a more uniform force through the rolling of the rollers 311 without changing the orientation of the workpiece 2000. This uniform force distribution allows the workpiece to work within a larger deformation range, thus withstanding greater deformation. Because roller die drawing can withstand a larger deformation, the required processing task can be completed in fewer passes, and die wear and tool breakage problems can be reduced to a certain extent. In roller die drawing, deformation is achieved through the continuous action of the rollers 311, which gradually guide the workpiece deformation, avoiding single-point stress concentration and reducing the risk of die tooth breakage. The use of roller die drawing also protects the mold, extends its service life, and effectively reduces mold costs.
[0039] Existing integrated drawing and peeling designs are primarily suitable for processing round bars or tubes, requiring extremely high workpiece symmetry. For workpieces of varying specifications and complex cross-sections, the processing difficulty is immense. Taking H-shaped guide rails as an example, the unique cross-sectional shape of H-shaped guide rails, with grooves and other structures, makes it difficult for existing molds to adapt to the processing requirements of such complex shapes. When processing the inner grooves of H-shaped guide rails, existing molds cannot accurately shape them, leading to processing difficulties and poor mold versatility. To process more complex products, in this embodiment, each roller group 310 includes two rollers 311, spaced apart, with their axes parallel to each other. This design allows the rollers 311 to better adapt to the complex cross-sectional shape of the H-shaped guide rail, enabling smoother processing of the left and right inner grooves.
[0040] Because the drawing assembly 300 uses a four-roll mill structure, the four rollers 311 cooperate to apply pressure of a specific direction and magnitude to the workpiece 2000. Under this pressure, the material on both sides of the workpiece 2000 undergoes plastic deformation, thereby creating left and right grooves. Simultaneously, the four corners gradually form radius (R-angle) under the squeezing and friction of the rollers 311. During this process, the design parameters of the drawing assembly 300's die (such as the diameter, spacing, and rotational speed of the rollers 311) and the process parameters of the drawing die (such as the pulling force and drawing speed) are carefully designed and adjusted to ensure that the material can be precisely processed according to the expected shape and size. When the workpiece 2000 enters the die assembly 200, the shape and size of the die assembly 200 match the workpiece 200, and its main function is to refine the edges of the workpiece 2000. Under the action of the die assembly 200, the four R-angles of the workpiece 2000 undergo further plastic deformation, gradually transforming into C-angles. Meanwhile, the groove area remains unaffected due to the design of the die assembly 200, maintaining its original shape and dimensions. This process achieves precise finishing of the workpiece 2000, ensuring that the final product meets higher requirements in terms of dimensional and shape accuracy, thereby improving product quality and precision.
[0041] Of course, the roller set 310 can also be used to process other workpieces with complex cross-sections, which is not limited here.
[0042] To ensure the straightness of the workpiece 2000, this embodiment uses two sets of rollers 310, arranged at right angles. The roller sets 310 in this embodiment include a first roller set 312 and a second roller set 313. The surface of the first roller set 312 has protrusions 3121. The two rollers 311 of the first roller set 312 and the second roller set 313 are respectively located on both sides of the workpiece 2000. The axes of the first roller set 312 and the second roller set 313 are perpendicular to the processing direction of the workpiece 2000; and the axis of the first roller set 312 is perpendicular to the axis of the second roller set 313. Of course, depending on the final shape of the workpiece 2000 to be processed, the two sets of rollers 310 can also be arranged at other angles, such as acute angles or obtuse angles, which are not limited here. The number of roller sets 310 can also be one, two, three, four, or more, depending on the actual processing requirements, and is not limited here. Furthermore, depending on the shape and structure of the workpiece to be processed, other drawing components 300 structures may be selected, and no limitation is made here. The number of rollers 311 included in each roller group 310 may be one, two, three, four, or more, depending on the actual processing requirements, and no limitation is made here. The surface shapes of the first roller group 312 and the second roller group 313 may also be determined according to the actual processing conditions, and no limitation is made here.
[0043] Please continue reading. Figure 1 and combined Figure 2 In this embodiment, the drawing device 1000 further includes a second guide 500, which is arranged parallel to the die assembly 200 and close to it. The second guide 500 guides the workpiece 2000 through the die assembly 200. The second guide 500 is parallel to and coaxial with the first guide 400. By setting the second guide 500, the dimensional accuracy and symmetry can be further corrected during the die finishing process, thereby improving the accuracy of the workpiece 2000. A guide (also called a guiding device or guide support) is a device used to ensure that the various parts of the die maintain accurate alignment and stability during the closing and opening process. They play the roles of guiding, positioning, stabilizing, and protecting. To further improve the accuracy of the workpiece 2000, there are two second guides 500 in this embodiment. The two second guides 500 are respectively arranged on both sides of the die assembly 200 along the parallel direction of the die assembly 200 and the drawing assembly 300. By providing second guides 500 on both the front and rear sides of the die assembly 200 along the processing direction, the precise alignment of the workpiece 2000 entering and exiting the die assembly 200 can be ensured, preventing misalignment or displacement of the die and ensuring the dimensional accuracy of the product. Of course, the second guides 500 can also be provided only between the die assembly 200 and the drawing assembly 300, or only on the side of the die assembly 200 away from the drawing assembly 300; there is no limitation here.
[0044] In addition, please see Figure 1 and Figure 2 and combined Figure 4 , Figure 4 This is a schematic diagram of a die assembly with a second guide provided in an embodiment of the present invention. To prevent the workpiece 2000 from warping at the head or tail, the second guide 500 in this embodiment can be designed as a hollow tube, through which the workpiece 2000 passes.
[0045] Figure 3 This is a schematic diagram of a pull-out assembly 300 with a first guide 400 provided in an embodiment of this utility model. Please refer to... Figure 1 and combined Figure 3In this embodiment, there are two first guides 400, which are respectively disposed on both sides of the drawing assembly 300 along the parallel direction of the die assembly 200 and the drawing assembly 300. By providing first guides 400 on both the front and rear sides of the drawing assembly 300 along the processing direction, the straightness of the guide rail can be ensured during the drawing process, reducing the impact of straightness issues on accuracy. Furthermore, the dimensional accuracy and symmetry can be further corrected in the subsequent die finishing stage, thereby effectively solving the problem of accuracy control of H-type guide rails in the prior art. Of course, the first guides 400 can also be disposed only between the drawing assembly 300 and the die assembly 200, or only on the side of the drawing assembly 300 away from the die assembly 200; this is not limited here.
[0046] By setting the first guide 400 and the second guide 500, the straightness of the guide rail is prevented from decreasing, and the workpiece positioning in the next process is made easier. During the drawing process, the workpiece 2000 undergoes plastic deformation under the action of the roller group 310. Without a suitable guide device, the workpiece may shift or oscillate under force, resulting in a decrease in the straightness of the guide rail. Adding the first guide 400 precisely guides the movement of the workpiece 2000, ensuring it maintains the correct direction and position throughout the drawing process, thus guaranteeing the straightness of the guide rail. Simultaneously, the first guide 400 and the second guide 500 also facilitate workpiece positioning in the next process. Because the first guide 400 and the second guide 500 can precisely define the position of the workpiece 2000, complex positioning operations are not required when the workpiece 2000 enters the next process. Only simple adjustments based on the positions of the first guide 400 and the second guide 500 are needed, greatly improving the accuracy and convenience of positioning.
[0047] To achieve automated continuous production, reduce manual operations, and improve production efficiency, please refer to [link / reference needed]. Figure 1In this embodiment, the drawing device 1000 further includes a pay-off frame 600 and a take-up frame 700. The pay-off frame 600 is located on the side of the drawing assembly 300 away from the die assembly 200, and the take-up frame 700 is located on the side of the die assembly 200 away from the drawing assembly 300. During processing, the workpiece 2000 is wound around the pay-off frame 600, passes through the drawing assembly 300 and the die assembly 200 in sequence, and returns to the take-up frame 700. In traditional processes, the drawn material needs to be manually transported to the finishing process, which is not only time-consuming and labor-intensive but may also cause damage to the material during transport. However, in this embodiment, by rationally setting the positions of each structure, the workpiece 2000, under the action of the drive component, can automatically pass through the drawing and die finishing stages in sequence from the pay-off frame 600 without much manual intervention, directly reaching the take-up frame 700. This greatly reduces the waiting and transport time between processes and improves production efficiency. At the same time, it also reduces the number of times materials are handled, lowers the risk of quality problems such as deformation and bumps caused by handling, and helps to improve product quality stability.
[0048] To ensure the stability of the workpiece 2000 during the entire processing process of the drawing device 1000 when processing a long workpiece 2000, the drawing device 1000 in this embodiment also includes a winding frame 800, which is disposed between the take-up frame 700 and the die assembly 200.
[0049] The drive assembly 100 in this embodiment includes a drive motor and a mounting bracket. The drive motor is mounted on the mounting bracket, and the die-cutting assembly 200 is also mounted on the mounting bracket. The drive motor is connected to both the die-cutting assembly 200 and the drawing assembly 300, and is used to drive the die-cutting assembly 200 and the drawing assembly 300 to operate. The take-up frame 700 and the pay-off frame 600 may also each be equipped with a drive component, which is used to drive the take-up frame 700 and the pay-off frame 600 to rotate, thereby moving the workpiece 2000. Of course, the drive motor can also be replaced with other drive components such as a motor, which is not limited here.
[0050] The working principle of the drawing device 1000 provided in this embodiment is as follows:
[0051] First, the raw bar stock undergoes hot rolling to produce a wire rod with an outer contour dimension close to that of the finished guide rail. This hot rolling process improves the material's microstructure, making it easier for subsequent processing. After surface lubrication, it is wound onto the wire rod pay-off frame 600. Surface lubrication reduces friction during subsequent drawing, lowers energy loss, and also helps improve the drawing surface quality. The outermost layer of wire rod on the pay-off frame 600 is headed to allow the workpiece 2000 to pass smoothly through the die. A drive motor applies tension, causing the headed portion to pass sequentially through the drawing assembly 300 and the die assembly 200. The drive motor precisely controls the drawing speed and tension by controlling its speed and torque. The workpiece with the headed portion, having passed through the die, is fixed or clamped onto the wire rod take-up frame 700 at the other end. Then, driven by the drive motor, the wire rod continuously rotates from the pay-off frame 600 to the take-up frame 700. In this process, the workpiece 2000, under the action of the mold, sequentially completes the roller drawing and die finishing steps, realizing automated and continuous production. This method reduces manual operation, lowers the errors and uncertainties caused by manual operation, saves labor resources, and improves production efficiency.
[0052] In summary, the drawing device 1000 includes a drive assembly 100, a die assembly 200, a drawing assembly 300, and a first guide 400. The die assembly 200 is connected to the drive assembly 100; the drawing assembly 300 is arranged side-by-side with the die assembly 200 and is connected to the drive assembly 100; the first guide 400 is arranged side-by-side with the drawing assembly 300 and is close to the drawing assembly 300. The first guide 400 is used to ensure the straightness of the workpiece 2000 during the drawing process. The drive assembly 100 drives the die assembly 200 to perform hole processing on the workpiece 2000 after passing through the die assembly 200. The drive assembly 100 drives the drawing assembly 300 to deform the workpiece 2000 during processing. By setting the first guide 400, the workpiece 2000 can be prevented from shifting or swaying during the force process, thereby improving the straightness of the workpiece 2000. By integrating drawing and die finishing, the waiting and handling time between processes can be reduced, and the operations of transferring and repositioning workpieces between different equipment can be reduced, thereby improving production efficiency, product stability and product quality.
