Description

Technical Field

[0001] The utility model relates to the technical field of steel cold drawing, in particular to a steel cold drawing device for producing weight sheets. Background Art

[0002] Weight plates are usually removable metal plates used to add weight to weightlifting equipment.

[0003] In the existing technology, weight plates are often produced through cold drawing technology. The end of the steel is passed through a specific hole in the cold drawing machine, and then the trolley on the cold drawing machine is driven to fix the end of the steel. Finally, the entire steel is pulled through the specific hole in the cold drawing machine by the trolley. The steel is extruded through the hole to obtain the required size, and then the required weight plate is obtained by shearing the steel.

[0004] However, when cold-drawing, the steel is long in length and the holes squeeze the steel, causing its surface temperature to rise sharply and its texture to soften, which can easily cause the steel to bend during cold drawing, affecting the next step of processing of the steel.

Since there are multiple sets of small pulleys on the surface of the splint, the splint will not hinder the cold plate of the steel. Under the limitation of multiple sets of clamping components, the steel is prevented from bending during cold drawing. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figures 1 to 5 The utility model provides a technical solution: a steel cold drawing device for producing weight plates.

[0026] In the first embodiment, a trolley 5 is provided on the surface of the cold drawing machine body 2, and a steel material 1 is fixed on the surface of the trolley 5. A fixing rod 3 is fixed on the upper surface of the side of the cold drawing machine body 2. The trolley 5 will pull the steel material 1 to move, and the fixing rod 3 is connected to the rotating sleeve 4 in a rotating movable manner. The rotating sleeve 4 can automatically reset to an angle at right angles to the steel material 1, so the rotating sleeve 4 that is not limited by the trolley 5 automatically rotates to be perpendicular to the steel material 1.

[0027] A lower support plate 15 and an upper support plate 16 are fixed to the surface of the rotating sleeve 4, a guide rod 7 is provided on the surface of the upper support plate 16, a connecting rod 20 is inserted through the end of the upper support plate 16, and a splint 14 is fixed to the end of the connecting rod 20. The movement of the guide rod 7 will drive the supporting block 11 to move, and the movement of the supporting block 11 will drive the transmission block 12 to move downward. The movement of the transmission block 12 will drive the splint 14 to move through the connecting rod 20. When the rotating sleeve 4 rotates to be perpendicular to the steel 1, the upper and lower sets of splints 14 are simultaneously supported on the upper and lower surfaces of the steel 1 to clamp the steel 1.

[0028] On the basis of Example 1, in order to prevent the steel 1 from bending during cold drawing, one end of the steel 1 is fixed to the end of the steel 1, and the other end of the steel 1 is fixed to the surface of the trolley 5. The rotating sleeve 4 is sleeved on the outer surface of the fixed rod 3, and the fixed rod 3 is fixed with an arc block 6 on the outer surface of the end. The slope of the arc block 6 gradually increases, so when the rotating sleeve 4 rotates, the arc block 6 will support the guide rod 7 through the roller 19 to make it move.

[0029] A splint 14 is fixed on the surface of the lower support plate 15, and a support ring 10 is fixed on the surface of the upper support plate 16. A positioning hole 17 is opened on the surface of the support ring 10. The positioning hole 17 is relative to and clamped with the guide rod 7. The support ring 10 supports and positions the guide rod 7 to prevent the guide rod 7 from offsetting when moving. The two are movably connected.

[0030] A roller 19 is provided at the end of the guide rod 7 close to the fixed rod 3, a baffle 8 is fixed to the outer surface of the guide rod 7, and a first spring 9 is sleeved on the outer surface of the guide rod 7.

[0031] A through hole 18 is formed on the surface of the upper supporting plate 16 , and the through hole 18 corresponds to and is locked with the connecting rod 20 , and the two are movably connected.

[0032] A transmission block 12 is fixed to the upper end of the connecting rod 20. The upper surface of the transmission block 12 is provided with a slope, which corresponds to the slope of the surface of the supporting block 11. Due to the existence of the slope, the movement of the supporting block 11 will drive the transmission block 12 to move downward.

[0033] A second spring 13 is sleeved on the outer surface of the connecting rod 20. The second spring 13 is located on the outer surface of the connecting rod 20 above the upper support plate 16. Due to the presence of the second spring 13, the transmission block 12 always remains in contact with the top holding block 11. A splint 14 is fixed to the lower end of the connecting rod 20, and the two sets of splints 14 correspond to the steel 1.

[0034] In actual use, when the steel 1 is cold drawn, the trolley 5 will pull the steel 1 to move, and the fixed rod 3 is connected to the rotating sleeve 4 in a rotating movable manner. The rotating sleeve 4 can automatically reset to an angle at right angles to the steel 1, so the rotating sleeve 4 that is not limited by the trolley 5 automatically rotates to be perpendicular to the steel 1. When the rotating sleeve 4 rotates, since the surface of the fixed rod 3 is fixed with an arc block 6, and the slope of the arc block 6 gradually increases, when the rotating sleeve 4 rotates, the arc block 6 will support the guide rod 7 through the roller 19 to make it move, and due to the presence of the first spring 9, the roller 19 always remains in contact with the arc block 6, and the guide rod 7 moves It will drive the holding block 11 to move. Due to the existence of the inclined surface, the movement of the holding block 11 will drive the transmission block 12 to move downward. Due to the existence of the second spring 13, the transmission block 12 always remains in contact with the holding block 11. The movement of the transmission block 12 will drive the clamping plate 14 to move through the connecting rod 20. When the rotating sleeve 4 rotates to be perpendicular to the steel 1, the upper and lower groups of clamping plates 14 are simultaneously supported on the upper and lower surfaces of the steel 1 to clamp the steel 1. Since multiple groups of small pulleys are provided on the surface of the clamping plate 14, the clamping plate 14 will not hinder the cold plate of the steel 1. Under the limitation of multiple groups of clamping components, the steel 1 is prevented from bending during cold drawing.
