Description

Technical Field

[0001] The present application relates to the technical field of steel strands, and in particular to a tunnel-type pickling and phosphating device for steel strands. Background Art

[0002] Stranded steel wire is a steel product consisting of multiple steel wires twisted together. The carbon steel surface can be coated with galvanized layer, zinc-aluminum alloy layer, aluminum clad layer, copper plating layer, epoxy resin coating, etc. as needed. The manufacturing process is divided into single wire manufacturing and stranded wire manufacturing. (Cold) wire drawing technology is used to make single wire. Depending on the product, the material can be high carbon steel wire rod, stainless steel wire rod or medium and low carbon steel wire rod. If galvanizing is required, electroplating or hot-dip galvanizing should be carried out on the single wire.

[0003] The existing patent (publication number: CN215163175U) has announced a steel strand pickling device, including a pickling tank, a support plate and a hoisting vibration mechanism; the hoisting vibration mechanism includes a mounting plate and a hanging plate, the hanging plate and the mounting plate are connected by at least two hangers, the at least two hangers are movably mounted on the support plate, the hanger is provided with a spring at a position between the support plate and the mounting plate, a vibrator is installed on the bottom surface of the mounting plate, and the hanging plate is provided with a hanging part for hanging the wire rod for the steel strand to be pickled. In this design, the support plate can move in the vertical direction to meet the requirements of the pickling state of the steel strand wire rod and the hanging cooling state after pickling, that is, to remove the pickling liquid carried by the wire rod, to prevent the wire rod from carrying too much pickling liquid into the cleaning tank, and to improve the subsequent water cleaning effect; at the same time, in this design, the setting of the vibrator allows the wire rod to vibrate and clean when immersed in the pickling liquid, thereby improving the pickling effect of the wire rod.

[0004] During the use of the above-mentioned document, since the steel strands are in a tightly wound state during pickling, it will be difficult to pickle the steel strands evenly, and since the flow of the pickling liquid is small, it will be difficult for the pickling liquid to enter the gaps of the steel strands, affecting the pickling effect of the steel strands.

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a plurality of fixed plates 10 are fixedly connected to a stirring plate 13 on a side away from each other, and the plurality of stirring plates 13 are distributed in a circle. The installation of the plurality of stirring plates 13 can stir the pickling liquid in the pickling frame 3, so that it can have an impact force to facilitate the pickling of the steel strands. A plurality of fixed frames 14 distributed in a circle are fixedly connected to the right side of the rotating ring 11, and a plurality of fixed frames 14 close to each other are slidably inserted with impact rods 15 on a side.

[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The outer surface of the pickling frame 3 is rotatably connected with a gear ring 18, and a motor 19 is installed on the right side of the support seat 2. The output end of the motor 19 is fixedly connected with a rotating rod 20, and the right end of the rotating rod 20 is fixedly connected with a gear 21. The gear 21 is meshed with the gear ring 18. The motor 19 can drive the rotating rod 20 to rotate, so that the gear 21 can mesh with the gear ring 18, thereby driving multiple fixed frames 14 to perform circular motion, so that the impact rod 15 can impact the pickling frame 3.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The left and right sides of the pickling frame 3 are fixedly connected with extension tubes 24, and the two extension tubes 24 are symmetrical. Installing the extension tubes 24 and keeping them horizontal with the pickling frame 3 can prevent the pickling liquid in the pickling frame 3 from being discharged, so that the pickling liquid can be stably stored in the pickling frame 3. Multiple springs 7 are in a reset state, and multiple elastic members 16 are in a reset state. Installing multiple elastic members 16 can push the impact rod 15 to impact the pickling frame 3 through the elastic deformation force of the elastic member 16, so that the vibration is transmitted to the pickling frame 3. Multiple fixing frames 14 are fixedly connected to the right side of the gear ring 18, and multiple impact rods 15 are in contact with the pickling frame 3. The gear 21 can drive the fixing frame 14 to make a circular motion during the rotation, so that the impact rod 15 contacts the top block 17 and compresses the elastic member 16.

[0038] A tunnel-type pickling and phosphating device for steel strands in the present embodiment can, by installing elastic pushers, sliding members, and extrusion members, enable multiple extrusion members to contact the steel strands during the pickling process of the steel strands, and the contact between the elastic plate and the fixed plate can drive the fixed frame to swing slightly, so that the multiple contact members can rotate in the opposite direction to the texture of the steel strands, so that the multiple steel wires of the steel strands can move away from each other, and the pickling liquid can enter the gaps between the multiple steel wires. When the pickling is completed, the multiple steel wires will fit together again, thereby improving the pickling efficiency of the steel strands.

[0039] The working principle of the above embodiment is as follows: first, the steel strand is put into the extension tube 24 on the left, and passes through the pickling frame 3 and out of the extension tube 24 on the right. At this time, the motor 19 is started and drives the rotating rod 20 to rotate. The rotating rod 20 can drive the gear 21 to mesh with the gear ring 18 during the rotation, and then drive the gear ring 18 to rotate. The gear ring 18 can drive multiple fixed frames 14 to make circular motions during the rotation. The fixed frame 14 can drive the impact rod 15 to contact the top block 17 when making a circular motion, and compress the elastic member 16. When the impact rod 15 is separated from the top block 17, the elastic deformation force of the elastic member 16 can push the impact rod 15 to collide with the pickling frame 3. By colliding with the pickling frame 3, the vibration can be transmitted to the pickling frame 3, and the pickling liquid can enter the gaps of multiple steel wires through vibration. When multiple fixed frames 14 make a circular motion, they can drive the rotating The moving ring 11 rotates, and the rotating ring 11 can drive the multiple fixed plates 10 to make circular motions during the rotation, so that the fixed plate 10 can drive the multiple stirring plates to stir the pickling liquid in the pickling frame 3, so that the pickling liquid can have impact force, and at the same time, the fixed plate 10 can drive the rotating frame 8 to rotate, and the rotating frame 8 can drive the multiple elastic pushers 9 to contact with the multiple sliding members 5 during the rotation, so that the multiple sliding members 5 can push the multiple extrusion members 6 to approach each other and contact the steel strands, and at the same time, the fixed plate 10 can push the elastic plate 12, so that the elastic plate 12 can drive the fixed frame 4 to swing slightly, at this time, the multiple extrusion members 6 can reversely twist the steel strands, so that the multiple steel wires forming the steel strands can be temporarily separated, so that the pickling liquid can enter the gaps between the multiple steel wires, and when the pickling is completed, the multiple steel wires will be re-attached together, thereby improving the pickling efficiency of the steel strands.
