Description

Technical Field

[0001] This utility model relates to the technical field of steel processing equipment, specifically a continuous cold drawing-straightening integrated device. Background Technology

[0002] Cold drawing is a process for manufacturing high-precision cold-drawn steel, using a cold drawing machine to draw steel wire or small steel billets into steel wires or rods of a specified diameter. During this process, the steel deforms due to stretching, generating stress and bending. Straightening is a process that straightens bent steel by using a straightening machine to stretch it into a straighter shape. Steel processing equipment is used in the processing of steel.

[0003] Existing steel processing equipment typically uses a separate design for the cold drawing machine and the straightening machine. This requires the steel to be transferred between the two machines during cold drawing and straightening, which is inconvenient and results in low work efficiency. Furthermore, the inability to limit the movement of the steel wire workpiece leads to weak stability during processing, which in turn affects product quality. Therefore, there is an urgent need for a continuous cold drawing-straightening integrated device to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a continuous cold drawing-straightening integrated device to solve the problems mentioned in the background art. Existing steel processing devices typically use a separate design for the cold drawing machine and the straightening machine, which requires the steel to be transferred between the cold drawing machine and the straightening machine during cold drawing and straightening. This makes processing inconvenient, results in low work efficiency, and secondly, it cannot limit the position of the steel wire workpiece, resulting in weak stability during processing, which in turn affects the quality of the product.

Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0022] Please see Figure 1-5 A continuous cold drawing-straightening integrated device includes a housing 1. Support legs 2 are connected to both sides of the bottom of the housing 1. Doors 5 are connected to both sides of the front end of the housing 1 via hinges 4. An entrance 3 is located in the middle of the left side wall of the housing 1. A drawing die 6 is installed inside the housing 1 on the left side. Four straightening rollers 7 arranged in pairs are located inside the housing 1 and to the right of the drawing die 6. Guide rails 8 are located to the right of the four straightening rollers 7. Connecting blocks 9 are installed in the grooves of the guide rails 8. A winding mechanism is located to the right of the guide rails 8. The rear end of the take-up roller 10 is equipped with a bearing seat 11 via a first bearing. One side of the bearing seat 11 is connected to the rear side wall of the housing 1. The front end of the take-up roller 10 is equipped with a driven sprocket 12. The driven sprocket 12 is connected to a driving sprocket 14 via a chain 13. The rear end of the driving sprocket 14 is connected to a motor 15. The bottom of the motor 15 is connected to the right side wall of the housing 1 via a motor mounting seat 16. The inner front and rear ends of the connecting block 9 are both connected to cylinders 17. One end of each cylinder 17 is connected to a limit block 18.

[0023] Among them, the cross-sectional shape of the connecting block 9 is a concave structure.

[0024] Each of the four straightening rollers 7 has a second bearing installed at its rear end, and the four second bearings are connected to the rear end face of the housing 1 through the second bearing seat.

[0025] Among them, an arc-shaped groove 19 is provided in the middle of one side of the limiting block 18.

[0026] The number of support feet 2 is set to four, and the four support feet 2 are arranged in pairs facing each other about the bottom of the box body 1.

[0027] The number of hinges 4 is set to four.

[0028] The working principle and usage process of this utility model are as follows: First, the steel wire blank is input from the inlet 3, then passes through the central hole of the drawing die 6, then through the middle of the upper and lower straightening rollers 7, and finally wound onto the take-up roller 10. At this time, the motor 15 is started to drive the drive sprocket 14 to rotate. The rotating drive sprocket 14 drives the driven sprocket 12 to rotate through the chain 13. The rotating driven sprocket 12 drives the take-up roller 10 to rotate, thereby realizing the winding. During the winding process, the steel wire blank is cold-drawn by the drawing die 6. After cold drawing, it is straightened by four straightening rollers 7 that are opposite each other in pairs. Then, two cylinders 17 are started to drive two limit blocks. The two opposing limit blocks 18 move in opposite directions, thereby limiting the straightened steel wire through the circular hole formed by the two arc grooves 19 on the two limit blocks 18. The straightened steel wire is limited by the circular hole formed by the two arc grooves 19, which improves the stability during processing and thus improves the quality of the product. Furthermore, by integrating cold drawing and straightening into one unit, the workpiece does not need to be transferred between the cold drawing machine and the straightening machine for processing, which makes processing convenient and improves the efficiency of cold drawing and straightening.
