Technical Field

[0001] This utility model relates to the field of stainless steel bar processing technology, specifically to a stainless steel bar production equipment with a fixed-point marking function. Background Technology

[0002] Stainless steel bar production equipment is specialized equipment used to process stainless steel raw materials into bars. Stainless steel bars are widely used in machinery manufacturing, construction, chemical industry, aerospace and other fields, and have characteristics such as high strength, corrosion resistance, and high temperature resistance. The production process of stainless steel bars typically includes steps such as smelting, casting, hot rolling, cold rolling, drawing, heat treatment, and surface treatment.

[0003] Existing stainless steel bar processing equipment often requires the use of external force or cumbersome manual operation to perform the marking of fixed-point lines on the bar surface, which is mostly done by using a marker and a support frame for adjustment. This results in the existing stainless steel bar processing equipment having to synchronize the fixed-point intermittent marking and auxiliary transport of the bar. Therefore, an improved device is needed to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides an embodiment of a stainless steel bar production equipment with a fixed-point marking function, including a bar processing device 3. Stainless steel bars 4 are placed inside the bar processing device 3. A contact device 1 is fixedly installed at the top front end of the bar processing device 3. An alignment device 2 is fixedly installed at the top end of the contact device 1. A transmission device 19 is fixedly installed at the end of the contact device 1 away from the bar processing device 3. The contact device 1 includes a plastic wheel 5, a hydraulic cylinder 6, a connecting base frame 7, a support shaft 8, a cam 9, and a first gear 20. The connecting base frame 7 is fixedly installed on the hydraulic cylinder 6. At the top of cylinder 6, support shaft 8 is rotatably mounted on the side of connecting base frame 7. Plastic wheel 5 is fixedly mounted on the side of support shaft 8 away from connecting base frame 7. First gear 20 is fixedly mounted on both sides of plastic wheel 5. Cam 9 is fixedly mounted on the side of first gear 20 away from support shaft 8. Transmission device 19 includes extension frame 21, drive motor 22, contact wheel 23 and second gear 24. Drive motor 22 is fixedly mounted on the bottom of drive motor 22. Contact wheel 23 is fixedly mounted on the side of drive motor 22. Second gear 24 is fixedly mounted on both sides of contact wheel 23.

[0020] The alignment device 2 includes a connecting base plate 10, a first piston rod 11, a marking pen 12, a contact circular plate 13, a first gasket 14, a return spring 15, a second gasket 16, a second piston rod 17, and an L-shaped air cylinder 18. The L-shaped air cylinder 18 is fixedly installed on the top of the connecting base plate 10. The first piston rod 11 is slidably inserted into the bottom end of the L-shaped air cylinder 18. The marking pen 12 is fixedly installed on the bottom end of the first piston rod 11. The second piston rod 17 is fixedly installed on the top of the outer ring of the L-shaped air cylinder 18 and slidably inserted into the top end of the L-shaped air cylinder 18. The first gasket 14 is fixedly installed on the end of the second piston rod 17 away from the L-shaped air cylinder 18. The return spring 15 is fixedly installed between the second gasket 16 and the first gasket 14. The contact circular plate 13 is fixedly installed on the side end of the first gasket 14. It is connected to the connecting base frame 7 through the connecting base plate 10, so that the L-shaped air cylinder 18 can be supported for operation.

[0021] The hydraulic cylinder 6 is symmetrically fixedly installed at the front end of the bar processing equipment 3. The side end of the connecting base plate 10 away from the contact circular plate 13 is connected to the connecting base frame 7. When the connecting base frame 7 moves up and down, it can drive the L-shaped air cylinder 18 to move simultaneously.

[0022] The cam 9 is aligned with the contact plate 13, which improves the docking accuracy between the cam 9 and the contact plate 13.

[0023] The top of the plastic wheel 5 is vertically aligned with the top of the stainless steel rod 4, which makes it easier for the stainless steel rod 4 to drive the plastic wheel 5 to make contact.

[0024] The interior of the L-shaped air cylinder 18 is hollow, and a sealed cavity is formed between the first piston rod 11, the L-shaped air cylinder 18, and the second piston rod 17. When the second piston rod 17 moves into the interior of the L-shaped air cylinder 18, it can drive the first piston rod 11 to move downward.

[0025] Working Principle: During operation, stainless steel bars 4 are fed into the bar processing equipment 3 for surface polishing. Then, when the stainless steel bars 4 are removed from the equipment 3, the hydraulic cylinder 6 is activated, causing the contact wheel 23 to move downwards until it contacts the top of the stainless steel bars 4. The contact wheel 23 has a plastic coating, and the plastic wheel 5 contacts and adheres to it. When the contact wheel 23 contacts the surface of the stainless steel bars 4, the drive motor 22 is activated, causing the contact wheel 23 and the second gear 24 to rotate simultaneously. As the contact wheel 23 rotates, it displaces the stainless steel bars 4, thus conveying them outwards. Furthermore, while the contact wheel 23 is rotating... The second gear 24 meshes with the first gear 20, causing the first gear 20 to drive the plastic wheel 5 to rotate. Simultaneously, when the plastic wheel 5 rotates, it drives the cam 9 to rotate until it contacts the contact plate 13. When the contact plate 13 is pressed by the cam 9, the rounded shape of both the top of the cam 9 and the outer ring of the contact plate 13 improves the smoothness of contact between them. The contact plate 13 can also be displaced by the cam 9. This displacement causes the first gasket 14 to move, allowing the second piston rod 17 to enter the L-shaped cylinder 18, causing the first piston rod 11 to move downwards. The vertical alignment of the marking pen 12 with the top of the stainless steel rod 4 further directs the downward movement of the first piston rod 11. During movement, the marking pen 12 can be driven to contact the top of the stainless steel rod 4, completing the marking work on the surface of the stainless steel rod 4. Subsequently, as the plastic wheel 5 continues to rotate, it can drive the cam 9 to pass through the contact plate 13. At this time, the elasticity of the return spring 15 will drive the first pad 14 to move away from the end of the L-shaped air cylinder 18, causing the first pad 14 to pull the second piston rod 17 from the inside of the L-shaped air cylinder 18 to move outward. Thus, the first piston rod 11 can drive the marking pen 12 to return upward, making it easier for the marking pen 12 to disengage from the stainless steel rod 4. In use, the contact wheel 23 drives the plastic wheel 5 to rotate, so that the plastic wheel 5 can drive the cam 9 to rotate, so that the cam 9 can intermittently contact the contact plate 13. When the cam 9 contacts the contact plate 13, it can squeeze the contact plate 13 to drive the second piston rod 17 into the L-shaped air cylinder 18. This allows the first piston rod 11 to drive the scribing pen 12 downward to contact the surface of the stainless steel rod 4, completing the scribing work. Subsequently, when the cam 9 disengages from the contact plate 13, the elasticity of the return spring 15 will drive the first washer 14 and the second piston rod 17 to reset, making it easier for the contact plate 13 to contact the cam 9 again. Furthermore, because the transmission ratio of the first gear 20 to the second gear 24 is 1:10, the contact wheel 23 can drive the stainless steel rod 4 to move to a certain length before the cam 9 can contact the release plate 13, completing the intermittent scribing process of the stainless steel rod 4 and finishing the work.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
