Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, and particularly relates to a stainless steel wire drawing device. Background Art

[0002] The metal wire drawing process is an important metal processing process. By applying an external force, the metal is forced through a die, thereby changing the cross-sectional area, shape, and size of the metal. This process can not only endow the metal surface with unique textures and textures, but also enhance its anti-fingerprint and wear-resistant properties. In the processing of stainless steel materials, the wire drawing process is widely used to create beautiful and practical products.

[0003] Stainless steel is a metal material with excellent corrosion resistance, high temperature resistance, and mechanical strength. After its surface is wire-drawn, it can present delicate and uniform patterns, which not only improves the aesthetics of the product, but also enhances its durability and practicality. In addition, stainless steel materials also have good workability, making the wire drawing process widely used in the production of stainless steel products.

[0004] However, in the existing stainless steel wire drawing device, the wire drawing wheel is fixed and cannot adjust the shape of the contact surface. For materials of different sizes or with bends, the efficiency is low or processing is impossible. Summary of the Invention

[0005] In view of the above technical problems, the present invention discloses a stainless steel wire drawing device, which can effectively solve the problems in the background art. When in use, the present invention can change the components to make the contact area between the wire drawing belt and the stainless steel larger or smaller. When the contact area is large, the pressure spreads, which is suitable for large-area uniform wire drawing of large parts, enabling large parts to be wire-drawn quickly. When the contact area is small, the pressure is concentrated, which is suitable for quick wire drawing of small parts. And when the contact area reaches the minimum, that is, when the auxiliary wheel is completely retracted, the lower end of the wire drawing belt forms the sharpest state, which can wire-draw the bent part of the bent stainless steel. Due to the large contact wheel of the traditional wire drawing device, it cannot change flexibly and cannot wire-draw the bent part. This device is also provided with two wire drawing mechanisms, which are independent of each other and can respectively carry wire drawing belts with different roughnesses to form different wire drawing effects. In this way, two stainless steel materials can be wire-drawn simultaneously, or two wire drawing effects can be operated on the same stainless steel material. When the two wire drawing mechanisms are working independently, the other one that is not in use can be raised without affecting the working wire drawing mechanism.

[0033] In an alternative embodiment of the embodiment of the present invention, as Figure 6 shown in the figure, a spring is provided inside the connector 2, and the spring presses outward against the telescopic rod 3.

[0034] Working principle: When in use, the present invention can perform diversified wire drawing on stainless steel materials. It can draw large-sized materials or small-sized materials. For large-sized materials, a method with a large contact area is adopted to complete quickly, and for small-sized materials, a method with a small contact area is adopted for flexible change. Specifically, the cylinder I 10 starts, driving the slider I 9 to slide up and down. Through the action of the connecting rod I 7 and the connecting rod II 8, the auxiliary wheel 5 is driven to unfold to be flush with the main wheel 4 or retracted for only using the auxiliary wheel 5, which can change the contact area of the wire drawing belt 6 with the stainless steel material. After adjustment, the stepping motor III 26 is started to drive the lead screw III 25 to rotate, thereby driving the cross beam 18 to reciprocate. Synchronously, the servo motor I 12 is started to drive the upper auxiliary wheel 5 to rotate, thereby driving the wire drawing belt 6 to rotate, thus completing wire drawing on the metal surface. The lead screw I 19 and the lead screw II 20 rotate under the drive of the stepping motor I 21 and the stepping motor II 22, and can drive the relative positions of the two sliding brackets 16 for position adjustment.

[0035] When encountering a bent stainless steel material, the form with the smallest contact surface is adopted, that is, the auxiliary wheel 5 is completely retracted. When the auxiliary wheel 5 moves to the bent part, the cylinder II 17 starts, driving the lifting frame 11 to rotate, so that the wire drawing part at the lowermost end makes an arc movement, thus completing wire drawing at the bent part.

[0036] According to the actual situation, it is also possible to choose to perform wire drawing on two stainless steel materials simultaneously, or to perform different wire drawing effects on different regions of the same stainless steel material, that is, the materials of the wire drawing belts 6 installed on the two wire drawing mechanisms are different, and the two wire drawing mechanisms can be used independently. The unused wire drawing mechanism is lifted. Specifically, the servo motor II 14 is started, thereby driving the lifting frame 11 to move relatively, lifting the connector 2 upward, that is, completing the lifting operation.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
