Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for bar steel, specifically to a surface treatment device for bar steel. Background Technology

[0002] Pickling of steel bars is a key pretreatment process used to remove oxides, rust and impurities from the surface of steel. Its purpose is to improve the surface quality of steel and provide ideal surface conditions for subsequent processes such as cold rolling, cold drawing, painting and galvanizing. The degree of contact between the pickling solution and the steel bars affects the surface treatment effect of the workpiece.

[0003] For example, patent CN212404293U discloses a pipe and rod pickling device, including a pickling tank for containing pickling solution; a pipe and rod material rack, including a protrusion and a strip structure with both ends bent towards the tank opening, the protrusion being located in the middle of the strip structure; the pipe and rod material rack is placed at the bottom of the pickling tank to support the pipe and rod material; the pipe and rod pickling device also includes a moving component for hoisting the pipe and rod material, the pipe and rod material being hoisted by the hoisting straps of the moving component to perform pickling; through this device, the surface of the pipe and rod material is uniformly contacted with the pickling solution, solving the current problems in the pipe and rod pickling process. Due to the potential for surface corrosion, foreign matter adhesion, and pitting defects caused by contact between tubes and bars, as well as between tubes and bars and material racks / slings, this method improves the quality of finished tubes and bars. In particular, it improves the pickling defects of rare metal tubes and bars, which have high surface quality requirements, achieving defect-free pickling of tubes and bars. During pickling, multiple steel bars are usually processed simultaneously. If the surface of multiple steel bars is not sufficiently in contact with the pickling solution, it will lead to incomplete pickling, residual iron oxide scale on the surface, and black spots, wavy or warped appearance on the surface of the steel bars, affecting the surface treatment quality of the workpiece.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing bar steel surface treatment equipment. Utility Model Content

[0005] The purpose of this invention is to provide a surface treatment equipment for bar steel, in order to solve the problem mentioned in the background art that when pickling is usually carried out simultaneously on multiple bar steels, the surface of the multiple bar steels is not in sufficient contact with the pickling solution, which leads to incomplete pickling, residual iron oxide scale on the surface, and black spots, wavy or warped appearance on the surface of the bar steel, affecting the surface treatment quality of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for bar steel, comprising a processing tank and a lifting frame slidably mounted longitudinally on the processing tank, a movable support slidably connected laterally on the lifting frame, and a storage basket for placing bar steel fixedly mounted on the movable support; a hollow guide column is fixedly mounted on the inner wall of the processing tank, and a vibration frame is slidably connected through the hollow guide column; a card seat that engages with the vibration frame is fixed at the bottom of the storage basket; and a vibration mechanism is provided in the processing tank to drive the storage basket to reciprocate and assist the bar steel in moving and pickling.

[0007] Preferably, the vibration mechanism includes a waterproof electric telescopic rod fixedly installed on the inner wall of the processing pool, a drive rod fixedly installed at the telescopic end of the waterproof electric telescopic rod, and a vibration frame fixedly installed on the drive rod; the vibration frame is correspondingly arranged outside the vibration frame.

[0008] Preferably, a movable disk is fixedly sleeved on the outside of the vibration frame, and a vibration spring is elastically connected between the movable disk and the hollow guide column, with the vibration spring sleeved on the outside of the vibration frame.

[0009] Preferably, the processing tank is equipped with a drive mechanism for lifting and dispersing steel bars to assist in pickling.

[0010] Preferably, the driving mechanism includes a guide column fixedly installed on the bottom surface of the processing pool, a T-shaped frame slidably connected through the guide column, the T-shaped frame being positioned directly below the storage basket, and the T-shaped frame moving upwards through the bottom of the storage basket.

[0011] Preferably, the T-shaped frame has a horizontally opened sliding groove, a sliding column is slidably connected in the sliding groove, a rotating rod is rotatably connected on the sliding column, and the other end of the rotating rod is rotatably connected to the guide column.

[0012] Preferably, a protruding rod is fixedly connected to the rotating rod, and a driven round rod is fixedly connected to the end of the protruding rod, with the driven round rod correspondingly arranged on the side of the vibration frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the surface treatment equipment for bar steel can control the reciprocating movement of the accumulated bar steel in the processing tank, and lift and disperse the bar steel to maintain sufficient contact between the bar steel and the pickling solution, thereby improving its surface treatment processing effect.

[0014] Furthermore, the processing tank is equipped with a vibration mechanism that drives the storage basket to move back and forth to assist the movement of the steel bars for pickling. The operation of the waterproof electric telescopic rod controls the reciprocating movement of the drive rod and the vibration frame. When the vibration frame moves laterally, it acts on the storage basket, and the storage basket drives the vibration frame below to move laterally synchronously. The vibration frame can control the lateral reciprocating vibration of the storage basket through the hollow guide column, the moving plate and the vibration spring, thereby dispersing the steel bars accumulated inside the storage basket, so that the steel bars can fully contact the pickling solution in the processing tank and improve their surface treatment effect.

[0015] Furthermore, the processing tank is equipped with a drive mechanism that lifts and disperses the steel bars to assist in the pickling process. When the vibrating frame moves laterally back and forth, it can intermittently push and squeeze the driven round rod, control the rotation of the convex rod and the rotating rod, and the rotating rod lifts the T-shaped frame, so that the T-shaped frame lifts the steel bars in the dispersed storage basket, further ensuring that the steel bars are in full contact with the pickling solution.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Example 1: Please refer to Figures 1-7The present invention provides the following technical solution: a surface treatment equipment for bar steel, comprising a processing tank 1 and a lifting frame 2 longitudinally slidably installed on the processing tank 1, a movable support 3 slidably connected laterally on the lifting frame 2, and a storage basket 4 for placing bar steel fixedly installed on the movable support 3; a hollow guide column 5 is fixedly installed on the inner wall of the processing tank 1, and a vibration frame 6 is slidably connected through the hollow guide column 5; a card seat 7 is fixed at the bottom of the storage basket 4 and engages with the vibration frame 6; a vibration mechanism is provided in the processing tank 1 to drive the storage basket 4 to reciprocate and assist the bar steel in moving and pickling.

[0027] The vibration mechanism includes a waterproof electric telescopic rod 8 fixedly installed on the inner wall of the processing pool 1. A drive rod 9 is fixedly installed at the telescopic end of the waterproof electric telescopic rod 8, and a vibration frame 10 is fixedly installed on the drive rod 9. The vibration frame 10 is correspondingly arranged outside the vibration frame 6.

[0028] A movable disk 61 is fixedly sleeved on the outside of the vibration frame 6, and a vibration spring 62 is elastically connected between the movable disk 61 and the hollow guide column 5. The vibration spring 62 is sleeved on the outside of the vibration frame 6.

[0029] The lifting frame 2 is moved upward away from the processing pool 1 by hoisting equipment or manual control. The steel bars are stacked in the storage basket 4. Then the storage basket 4 is moved downward into the processing pool 1. The card seat 7 at the bottom of the storage basket 4 is engaged and installed on the vibration frame 6. An appropriate amount of pickling solution is added to the processing pool 1. The surface of the steel bars in the storage basket 4 comes into contact with the pickling solution, thus completing the surface treatment of the workpiece.

[0030] The operation of the waterproof electric telescopic rod 8 controls the drive rod 9 to move laterally back and forth. The drive rod 9 drives the vibration frame 10 to move laterally synchronously. When the vibration frame 10 moves laterally, it acts on the outside of the storage basket 4, pushing the storage basket 4 to move laterally synchronously. When the storage basket 4 moves laterally, it drives the vibration frame 6 below to move synchronously through the card seat 7. The vibration frame 6 slides through the hollow guide column 5. Under the elastic thrust of the vibration spring 62, the vibration frame 6, card seat 7 and storage basket 4 reciprocate in the lateral direction, thereby dispersing the bar steel inside the storage basket 4, keeping the bar steel in full contact with the pickling solution inside the processing tank 1, and also making the pickling solution evenly dispersed, thus improving the surface treatment effect of the bar steel.

[0031] Example 2: Please refer to Figures 1-8 Based on Embodiment 1, a driving mechanism is also disclosed, the specific structure of which is as follows: A driving mechanism for lifting and dispersing steel bars to assist in pickling is provided in the processing tank 1. The driving mechanism includes a guide column 11 fixedly installed on the bottom surface of the processing tank 1, through which a T-shaped frame 12 is slidably connected. The T-shaped frame 12 is located directly below the storage basket 4, and the T-shaped frame 12 moves upward through the bottom of the storage basket 4.

[0032] The T-shaped frame 12 has a horizontally opened sliding groove 13, and a sliding column 14 is slidably connected in the sliding groove 13. A rotating rod 15 is rotatably connected to the sliding column 14, and the other end of the rotating rod 15 is rotatably connected to the guide column 11.

[0033] A protruding rod 16 is fixedly connected to the rotating rod 15, and a driven round rod 17 is fixedly connected to the end of the protruding rod 16. The driven round rod 17 is correspondingly arranged on the side of the vibration frame 10.

[0034] When the vibrating frame 10 moves laterally, it contacts and presses against the driven round rod 17. The driven round rod 17 is pressed and drives the protruding rod 16 and the rotating rod 15 to rotate. When the rotating rod 15 rotates, it pushes the sliding column 14 to engage in the sliding groove 13 and slide. With the cooperation of the rotating rod 15 and the sliding column 14, the T-shaped frame 12 can be lifted, so that the T-shaped frame 12 moves longitudinally through the guide column 11. When the T-shaped frame 12 moves upward, it lifts the steel bars piled up in the storage basket 4. The piled steel bars are continuously lifted and then fall. Combined with the lateral vibration of the storage basket 4, the distance between the piled steel bars is larger, and the pickling liquid can flow into the gaps of the steel bars, further improving the surface treatment effect of the steel bars.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
