A feeding cover is fixedly connected to the front end of the outer shell by bolts. The feeding cover is communicated with the outer shell. A machine cover is installed on the upper side of the feeding cover. A straightening mechanism and a compensation mechanism are arranged on the outer shell. There are two groups of the straightening mechanisms, and the two groups of the straightening mechanisms are arranged oppositely. During operation, the second drive motor drives the worm gear, so that the material is straightened and stretched under the action of the first straightening wheel and the second straightening wheel, thus facilitating the development of the next drawing work. The structure is not only simple and convenient for later disassembly and maintenance. However, when using the above device, it can only draw metal products with a certain specification, and it is not convenient to adjust according to the size of the metal, so that the fastening effect during the drawing of the metal is poor, affecting the drawing effect of the metal.

[0034] The following is combined with Figures 1 to 2 The utility model is further introduced in detail.

[0035] Production drawing machines with positioning and clamping structures, such as Figure 1 As shown, it includes a housing 1 and auxiliary wheels 2 symmetrically mounted on both ends of the housing 1, and the two auxiliary wheels 2 are connected to the metal to be drawn. For example, the drawn metal can be a titanium product. It also includes:

[0036] The positioning and clamping components 3 are symmetrically arranged at both ends of the shell 1. The positioning and clamping components 3 are movably connected to the upper and lower sides of the auxiliary wheels 2. Furthermore, the positioning and clamping components 3 are used to drive the two auxiliary wheels 2 to the opposite ends, thereby realizing the tightening or loosening of the two auxiliary wheels 2 on the metal to be drawn.

[0037] The lubricating components 4 are symmetrically arranged on both sides of the housing 1 . The lubricating components 4 are attached to the two auxiliary wheels 2 . Furthermore, the lubricating components 4 are used to lubricate the two auxiliary wheels 2 .

[0038] Through the cooperation between the positioning clamping component 3 and the two auxiliary wheels 2, when the drawing machine draws the metal, the positioning clamping component 3 drives the two auxiliary wheels 2 to tighten the metal, and then it can be adjusted according to the size of the metal, so that the drawing machine improves the drawing effect of the metal. Further, through the cooperation between the lubrication component 4 and the positioning clamping component 3, when the metal is fixed, the lubrication component 4 applies lubricating oil to the auxiliary wheels 2, thereby further improving the lubrication during the drawing process and avoiding wear of the metal during the drawing process.

[0039] Specifically, Figure 1 and Figure 2 As shown, the positioning clamping assembly 3 includes:

[0040] There are four drive motors 31, which are fixed to the outside of the shell 1 near the auxiliary wheel 2.

The two sliding blocks 33 drive the two connecting blocks 35 to move relatively. Then, the two connecting blocks 35 drive the sliding rods 34 to move through the two connecting blocks 35. Further, the sliding rods 34 drive the auxiliary wheels 2 to move, so as to realize the fastening of the metal to be drawn by the two auxiliary wheels 2.

[0046] Specifically, as Figure 1 and Figure 2 shown, chutes corresponding to the positions of the sliding rods 34 and adapted to the movement tracks are provided at both the upper and lower ends inside the housing 1.

[0054] Specifically, as Figure 1 and Figure 2 shown, the shape of the auxiliary wheel 2 is concave, the shape of the lubricating wheel 44 is convex, the installation positions of the lubricating wheel 44 and the auxiliary wheel 2 correspond to each other. During use, the lubricating wheel 44 applies lubricating oil on the auxiliary wheel 2, thereby effectively avoiding wear when the metal is drawn.

[0058] Furthermore, lubricating oil is provided inside the placement shells 47. Both lubricating wheels 44 contact the lubricating oil, and both lubricating wheels 44 are always attached to the auxiliary wheel 2 under the pulling of the spring 45, thereby improving the attachment effect between the lubricating wheel 44 and the auxiliary wheel.

[0059] Specifically, as Figure 1 and Figure 2 shown, openings adapted to the moving trajectories of the two lubricating wheels 44 are provided on the opposite sides of the two placement shells 47.

[0060] Working principle

[0061] During use, the outer shell 1 is installed at a suitable position on the drawing machine. The metal to be drawn passes through between the two auxiliary wheels 2. When the drawing tightens the metal, when the drive motors 31 on the upper and lower sides at one end of the outer shell 1 are started, the drive motors 31 drive the lead screws 32 to rotate. The two sliding blocks 33 drive the two connecting blocks 35 to move relatively. Then, the two connecting blocks 35 drive the sliding rod 34 to move through the two connecting blocks 35. Then, the sliding rod 34 drives the auxiliary wheel 2 to move, thereby realizing the fastening of the two auxiliary wheels 2 to the metal to be drawn. At the same time, the lubricating wheel 44 applies the lubricating oil inside the placement shell 47 on the auxiliary wheel 2, thereby effectively avoiding wear when the metal is drawn.
