[0002] Cold drawing is a material processing technique used for metal materials. Cold drawing refers to drawing materials at room temperature in order to achieve a certain shape and mechanical properties. Compared with thermoformed products, cold-drawn products have the advantages of higher dimensional accuracy and better surface finish.

[0003] The existing technology has the following problems:

[0004] Existing large-scale cold-drawing pipe equipment lacks positioning of the workpiece in the front-back direction when conveying the workpiece, which makes it easy for the angle between the workpiece and the drawing die to deviate during cold drawing, thus affecting the cold drawing effect and hindering the use of the cold drawing machine. At the same time, existing cold drawing machines are not convenient for disassembling and replacing the drawing die when cold drawing pipes of different shapes and sizes, making the use of the cold drawing machine very inconvenient.

[0025] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0026] like Figure 1-3 As shown, this utility model provides a high-precision large-scale cold-drawn tube equipment, including a cold-drawing worktable 1. A connecting slide 2 is slidably connected to the top right side of the cold-drawing worktable 1. A clamping assembly 3 is provided on the top of the connecting slide 2. A traction worktable 4 is fixedly connected to the left end of the cold-drawing worktable 1. Several guide supports 5 are fixedly connected to the top of the traction worktable 4. A connecting bracket 6 is fixedly connected to the top left side of the cold-drawing worktable 1. A connecting insert plate 7 is slidably inserted into the inner side of the connecting bracket 6. The guide support 5 includes a U-shaped support plate 51, which is fixedly connected to the top of the traction worktable 4. A horizontal guide roller 52 is movably connected above the inner surface of the U-shaped support plate 51. A bidirectional screw 53 is movably connected to the bottom end of the inner surface of the U-shaped support plate 51. Threaded sliding plates 54 are threadedly connected to both the front and rear sides of the outer surface of the bidirectional screw 53. The lower surface of the threaded sliding plate 54 is slidably connected to the lower surface of the inner wall of the U-shaped support plate 51. Vertical guide rollers 55 are movably connected to the top left and right ends of the threaded slide plate 54. A knob 56 is movably connected to the lower front surface of the U-shaped support plate 51. Movable grooves are opened on the front and rear sides of the interior of the U-shaped support plate 51. The front and rear ends of the bidirectional screw 53 pass through the interior of the two movable grooves and are fixedly connected to bevel gears 57. The front end of the bevel gear 57 is fixedly connected to the rear end of the knob 56. The top of the outer surface of the bevel gear 57 is meshed with a bevel gear 58. The top of the bevel gear 58 is fixedly connected to a threaded column 59. Sliding grooves are opened on the upper front and rear sides of the inner surface of the U-shaped support plate 51. The top of the threaded column 59 passes through the interior of the sliding groove and is threadedly connected to a connecting slider 510 on its outer surface. The outer surface of the connecting slider 510 is slidably connected to the inner surface of the sliding groove. The opposite surfaces of the two connecting sliders 510 are movably connected to the front and rear ends of the horizontal guide roller 52.

[0027] When conveying cold-drawn workpieces, the workpieces are placed on horizontal guide rollers 52. By rotating knob 56, bevel gear 57 drives bidirectional screw 53 to rotate, allowing threaded slide plate 54 to slide inside U-shaped support plate 51. This, in turn, drives vertical guide roller 55 to slide, facilitating the clamping and positioning of the cold-drawn workpieces and preventing angular deviations during conveying. This ensures that the cold-drawing accuracy of the workpieces is not affected. Simultaneously, bevel gear 57 also drives bevel gear 58 to rotate, causing threaded column 59 to drive connecting slider 510 to slide inside sliding groove 1. This facilitates synchronous adjustment of the height of horizontal guide roller 52, making it easier to position and convey workpieces of different sizes, thus making the cold-drawing machine more convenient to use.

[0028] like Figure 4-5 As shown, this utility model provides a high-precision large-scale cold-drawing tube equipment. U-shaped clamps 61 are fixedly connected to the front and rear sides of the top of the connecting bracket 6. The front sides of the outer surface of the connecting insert 7 are slidably connected to the inner surfaces of the two U-shaped clamps 61 respectively. Two fixing slots 62 are opened on the left and right sides of the inner surface of the U-shaped clamps 61. A drawing die seat 71 that passes through the middle of the connecting insert 7 is fixedly connected. Fixing mechanisms 72 are provided on the front and rear sides of the top of the connecting insert 7. The fixing mechanism 72 includes a second knob 721, which is movably connected to the front and rear sides of the top of the connecting insert 7. A bidirectional screw 722 is fixedly connected to the bottom end of the second knob 721. The interior of the connecting insert 7... Both sides are provided with sliding grooves II. The bottom end of the bidirectional screw II 722 passes through the interior of the sliding groove II, and the upper and lower sides of the outer surface are threaded with threaded sliders 723. The threaded sliders 723 are slidably connected to the interior of the sliding groove II. The front and rear sides of the outer surface of the threaded sliders 723 are movably connected with two push rods 724. The end of the four push rods 724 on the same side away from the threaded sliders 723 is movably connected to a sliding push plate 725. The outer surface of the sliding push plate 725 is slidably connected to the inner surface of the sliding groove II. The upper and lower ends of the sliding push plate 725 are fixedly connected with fixed inserts 726. The end of the fixed inserts 726 away from the sliding push plate 725 passes through the interior of the fixed slot 62.

[0029] When installing the draft die holder 71 on the cold drawing machine, the connecting plate 7 is first slid into the U-shaped clamp 61. By rotating the knob 721, the bidirectional screw 722 drives the threaded slider 723 to slide inside the sliding groove. Under the push of the push rod 724, the sliding push plate 725 drives the fixed insert 726 to slide, so that the fixed insert 726 can be inserted into the fixed slot 62, thereby fixing the connecting plate 7 and completing the installation of the draft die holder 71, making the use of the cold drawing machine more convenient.

[0030] The working principle of this high-precision large-scale cold-drawn tube equipment will be explained in detail below.

[0031] like Figure 1-5 As shown, when using the cold-drawing tube equipment, the connecting insert plate 7 is first slid into the U-shaped clamping plate 61. By rotating the knob 721, the bidirectional screw 722 drives the threaded slider 723 to slide. Under the push of the push rod 724, the sliding push plate 725 drives the fixed insert block 726 to insert into the fixed slot 62, thereby realizing the installation and fixation of the connecting insert plate 7 and the drafting base 71. Then, the workpiece is placed on the horizontal guide roller 52 and passes through the middle of the drafting base 71. By rotating the knob 56, the bevel gear 57 drives the bidirectional screw 53 to rotate, thereby allowing the threaded slide plate 54 to slide on the inner side of the U-shaped support plate 51, which in turn drives the vertical guide roller 55 to slide, facilitating the clamping and positioning of the cold-drawn workpiece. Then, the cold-drawn workpiece is clamped by the clamping assembly 3, and the workpiece can be cold-drawn by the lateral sliding of the connecting slide table 2.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
