[0037] Embodiment one: please refer to Figures 1-7 A steel cold drawing machine, comprising: a rack 1 and a mounting plate 2 provided on the rack 1, further comprising: a movable plate 3 mounted on the rack 1, a traction mechanism 4 provided on the rack 1, the traction mechanism 4 is used to drive the movable plate 3 to move on the mounting plate 2, and the movable plate 3 is provided with a positioning mechanism 5, the positioning mechanism 5 is used for clamping and positioning the steel, and a powder box 6 is fixed on the mounting plate 2, the mounting plate 2 is fixed with a die mounting hole 7 for the steel to pass through, the die mounting hole 7 is provided for installing the cold drawing die, and the mounting plate 2 is fixed with a collecting box 8 below the powder box 6, the collecting box 8 is provided with a feeding assembly 9, the feeding assembly 9 transmits the lubricating powder in the collecting box 8 to the powder box 6;

[0038] It should be noted that the traction mechanism 4 mainly includes: a shaft, a chain, a sprocket, a pulley, a belt, a speed reducer and a driving motor, which provides power, and the power is transmitted to the shaft through the speed reducer, so that the traction mechanism 4 generates strong pulling force, and the steel is positioned through the positioning mechanism 5, and then the steel is pulled through the cold drawing die, so as to realize the cold drawing demand of the steel;

[0039] It should be noted that the traction mechanism 4 is specifically operated as follows: through the driving of the driving motor, the driving force is transmitted to the shaft through the speed reducer, the pulley and the belt, and then the sprocket is driven to rotate synchronously, so that the chain can be driven to work, so as to realize the accurate control of the traction for the steel cold drawing. This is a conventional setting in the art, so it will not be described in detail here.

[0040] Among them, at least two guide grooves are fixed on the rack 1, and the movable plate 3 slides in the guide groove through the guide wheel, so as to provide sufficient guiding action for the forced movement of the movable plate 3, ensure that the movable plate 3 moves in a smooth and stable state, and avoid the phenomenon of jamming or frustration.

[0041] Further, as Figures 1-4As shown, the positioning mechanism 5 comprises: a cylinder 51 fixed on the movable plate 3, the output end of the cylinder 51 is fixed with a transmission ring 52, a center rod 53 is fixed on the movable plate 3, and two clamping positioning plates 54 are rotatably connected on the center rod 53, the clamping positioning plates 54 are provided with recesses 16, and anti-skid blocks 17 are clamped in the recesses 16, the two clamping positioning plates 54 are slidably connected on the transmission ring 52 through connecting rods 55, the two connecting rods 55 are cross-distributed, the two connecting rods 55 are rotatably connected through a rotating rod 56, and the movable plate 3 is provided with a hanging assembly 10 matched with the traction mechanism 4;

[0042] Specifically, the hanging assembly 10 comprises: a support 101 fixed on the movable plate 3, a hook 102 rotatably connected on the support 101, and an electric push rod a 103 rotatably connected on the support 101, and the output end of the electric push rod a 103 is rotatably connected with the hook 102;

[0043] Wherein, the electric push rod a 103 is pressed, so that the hook 102 is forced to overturn downward, causing the hook 102 to be hung with the chain, thereby achieving the purpose of hanging the movable plate 3 with the chain, and ensuring that the positioning mechanism 5 can move under the traction of the chain;

[0044] It should be noted that through the setting of the positioning mechanism 5, the two clamping positioning plates 54 can be precisely and synchronously driven to approach the steel and complete clamping work, which has the advantages of good clamping stability and high reliability, and can avoid the situation that clamping loosening causes falling, thereby further ensuring the security of steel cold drawing;

[0045] The principle of clamping and positioning the steel by the positioning mechanism 5 is as follows: through the driving of the cylinder 51, the transmission ring 52 moves, the connecting rods 55 are driven, and the rotating rod 56 acts as a center support, so that the clamping positioning plates 54 are forced to overturn along the center rod 53, until the clamping positioning plates 54 completely clamp the steel, thereby completing the clamping and positioning of the steel.

[0046] Example two: refer to Figures 5-7 As shown, the embodiment further illustrates example one, and the difference lies in that the way of collecting and utilizing the lubricating powder is disclosed.

[0047] Specifically, the feeding assembly 9 comprises a feeding pipe 91 fixed in the collecting box 8, the feeding pipe 91 penetrates the powder box 6 in the vertical direction, an inlet slot 92 is arranged on one side wall of the powder box 6 where the feeding pipe 91 is located, a micro motor 93 is fixed on the feeding pipe 91, a spiral blade rod 94 is coaxially fixed on an output shaft of the micro motor 93, the spiral blade rod 94 is rotationally connected with the feeding pipe 91, and an outlet slot 95 is arranged on one side wall of the powder box 6 where the feeding pipe 91 is located; the powder box 6 is in an inverted trapezoidal shape, and the central section of the powder box 6 is arranged on the same plane as the central section of the feeding pipe 91;

[0048] It should be noted that, through the setting of the feeding assembly 9, the excess part of the lubricating powder applied to the surface of the steel material can be collected and concentrated, and the lubricating powder collected and concentrated can be delivered into the powder box 6, so that the lubricating powder can be recycled to the maximum extent, and the waste of the lubricating powder can be avoided, thereby reducing the cost of the cold-drawing processing of the steel material.

[0049] Further, the powder box 6 is fixed with a mounting plate 11, the mounting plate 11 is fixed with an electric push rod b12, an output end of the electric push rod b12 is fixed with a blocking block 13, a bottom end side wall of the blocking block 13 is arranged in an inverted bevel shape, the size value of the blocking block 13 is consistent with the size value of the outlet end of the powder box 6, and the blocking block 13 is slidably connected with the inner side wall of the powder box 6. Through the addition of the electric push rod b12 and the blocking block 13, the discharging state of the lubricating powder in the powder box 6 can be automatically completed, and the discharging amount of the lubricating powder can be better controlled. The collecting box 8 is located directly below the powder box 6, and the inner side wall of the collecting box 8 is arranged in an inverted bevel shape.

[0051] The present scheme is based on the working principle of the cold-drawing of the steel material:

[0052] Firstly, the staff inserts the steel material into the mold mounting hole 7, drives the blocking block 13 to move upward by the electric push rod b12, so that the lubricating powder in the powder box 6 falls onto the surface of the steel material, and the steel material passes through the mold mounting hole 7 and is clamped and positioned by the positioning mechanism 5;

[0053] Secondly, the positioning mechanism 5 is connected with the traction mechanism 4 through the hanging assembly 10, and the traction mechanism 4 provides a traction force;

[0054] Finally, the steel is forced to pass through the die hole which is smaller than the original diameter of the steel at normal temperature after the steel passes through the cold-drawing die installed in the die installation hole 7, so as to realize the reduction of the diameter of the steel, the increase of the length and the change of the performance.
