Description

Technical Field

[0001] The present invention relates to the field of steel bar rust removal equipment, and particularly relates to a pre-treatment device and method for steel bars used in precast beams. Background Art

[0002] In civil engineering, reinforced concrete and prestressed reinforced concrete are the main building components, playing an extremely important load-bearing role. In order to facilitate construction, generally, beams are prefabricated. During construction, the beams are then pulled over for erection and forming, thus completing the installation of the beams and making the construction simpler. Mainly, concrete bears the pressure and steel bars bear the tension. Rust on steel bars will not only reduce their cross-sectional area, causing the load-bearing capacity of components to decline, but also reduce the bond strength between the steel bars and the concrete, affecting the performance of their combined work. To meet the requirements of the project, it is necessary to remove the rust from the steel bars before use. In the prior art, when removing rust from steel bars, a grinding machine is generally used, and the steel bars are ground and rust-removed by a rotating grinding disc. However, the steel bars often bend, resulting in insufficient contact between the bent parts of the steel bars and the grinding components, thus affecting the grinding effect. At the same time, burrs often occur after the steel bars are ground, which can cause harm to workers during subsequent use. Therefore, we propose a pre-treatment device and method for steel bars used in precast beams to solve the above-mentioned problems. Summary of the Invention

[0008] Preferably, a set of straightening wheels is arranged on one side of the mounting frame. The straightening wheels are respectively arranged on the upper and lower parts of the steel bar body.

[0009] Preferably, a fixing frame is arranged on the side of the mounting frame away from the straightening wheels. The fixing frame is installed on one side inside the machine shell.

The fixing ring is fixedly connected to the outer periphery of the mounting ring, and the mounting ring is fixedly connected to the outer periphery of the mounting sleeve.

The ends of the spring sleeves away from the rotating plates are all rotatably connected to the upper parts of one ends of the fixing plates.

[0013] Preferably, a method for pretreating steel bars for prefabricated beams comprises the following steps: S1. In actual use, people first pass the steel bar body to be ground into the material port at the inlet end, and use the straightening wheel to straighten the steel bar body before grinding. The straightened steel bar body will continuously contact multiple rust removal rollers, and the servo motor uses the rotating shaft to drive each rust removal roller to rotate, and the steel bar body is fully ground and rusted by the continuous multiple rust removal rollers; S2. During the grinding process, the electric push rod drives the driving plate to move, and the meshing teeth on the inner side of the reserved groove on the driving plate drive the various fixed gears meshing with it to rotate synchronously, and the fixed gears drive the various rust removal rollers to deflect during the grinding process, so that the rust removal rollers are in more comprehensive contact with the steel bar body; S3, by staggering the rust removal rollers and then deflecting them during the working process of the rust removal rollers, the steel bar body is further corrected and supported during the grinding process of the steel bar body, so that when the rust removal rollers are grinding, the steel bar body is fully subjected to the friction force applied by the rust removal rollers, thereby avoiding bending of the steel bar body in the middle; S4. After being polished by the rust removal roller, the steel bar body will pass through the installation sleeve, and the grinding block inside the installation sleeve will further polish the steel bar body. The elastic support ring at the bottom of the grinding block will support the grinding block, so that the grinding blocks will fully contact with each other and wrap the steel bar body to a certain extent. S5. After grinding is completed, the air pump discharges high-impact airflow through the nozzle to clean the steel bar body, thereby blowing off the grinding debris attached to the steel bar body, and then the grinding wheel is used to grind and remove the larger burrs produced by grinding the steel bar body.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In actual use, people can first pass the steel bar body to be ground into the material port at the inlet end, and use the straightening wheel to straighten the steel bar body before grinding, so as to avoid the situation that the steel bar body is bent during the grinding process, resulting in the bending part not being able to fully contact with the grinding component and affecting the grinding effect. The straightened steel bar body will continuously contact multiple rust removal rollers, and the servo motor can use the rotating shaft to drive each rust removal roller to rotate. The continuous multiple rust removal rollers can achieve sufficient grinding and rust removal of the steel bar body, and the bristles intermittently arranged on the rust removal roller can sweep away the grinding debris on the steel bar body during the grinding process, so as to avoid the debris affecting the subsequent grinding of the steel bar body by the rust removal roller.

[0015] During the grinding process, the electric push rod can drive the driving plate to move, and the meshing teeth on the inner side of the reserved groove on the driving plate can drive the various fixed gears meshing with it to rotate synchronously, and the fixed gears can drive the various rust removal rollers to deflect during the grinding process, so that the rust removal rollers can be in more comprehensive contact with the steel bar body, thereby avoiding the situation where the rust removal rollers are in contact with the steel bar body at only a single point, resulting in excessive wear and affecting the service life, which is beneficial to actual use.

[0016] By staggering the rust removal rollers and then deflecting them during their operation, the steel bar body can be further corrected and supported during the grinding process. This allows the steel bar body to be fully subjected to the friction force applied by the rust removal rollers when the rust removal rollers are grinding, thereby avoiding bending of the steel bar body in the middle, resulting in insufficient contact and affecting grinding, which is beneficial to actual use.

[0017] After being polished by the rust removal roller, the steel bar body will pass through the installation sleeve. The grinding block inside the installation sleeve can be used to further polish the steel bar body. The elastic support ring at the bottom of the grinding block can support the grinding block so that the grinding block can fully contact with the grinding block. Since the grinding block is a soft grinding material, the grinding block can wrap the steel bar body to a certain extent, making the grinding effect of the steel bar body more outstanding.

[0018] After grinding is completed, the air pump can discharge high-impact airflow through the nozzle to clean the steel bar body, thereby blowing off the grinding debris attached to the steel bar body and completing the cleaning of the steel bar body. Afterwards, the grinding wheel can be used to remove the larger burrs produced after grinding the steel bar body, avoiding subsequent injuries to workers and facilitating actual construction work.

[0019] The working of the reduction motor can drive the driving gear to rotate, and the driving gear can use the ring tooth groove to drive the mounting ring to rotate, and the mounting ring can drive the mounting sleeve and each rotating plate to rotate, thereby driving each grinding block and grinding wheel to rotate synchronously, so that the steel bar body can be fully ground and cleaned, which is beneficial to actual use.

[0028] Among them, a method for pretreating steel bars for prefabricated beams comprises the following steps: S1. In actual use, people can first pass the steel bar body 104 to be ground into the material port 102 at the inlet end, and use the straightening wheel 110 to straighten the steel bar body 104 before grinding.

At the same time, By staggering the rust removal rollers 125 and then deflecting them during the working process of the rust removal rollers 125, the steel bar body 104 can be further corrected and supported during the grinding of the steel bar body 104, so that when the rust removal rollers 125 are grinding, the steel bar body 104 can be fully subjected to the friction force applied by the rust removal rollers 125, thereby avoiding bending of the steel bar body 104 in the middle, resulting in insufficient contact and affecting the grinding, which is beneficial to actual use. After being ground by the rust removal rollers 125, the steel bar body 104 will pass through the installation sleeve 113, and the grinding block 114 inside the installation sleeve 113 can further grind the steel bar body 104, and the elastic support ring 122 at the bottom of the grinding block 114 can be used to achieve The support of the grinding block 114 is now provided, so that the grinding block 114 can fully contact with the grinding block 114. Since the grinding block 114 is a soft grinding material, the grinding block 114 can wrap the steel bar body 104 to a certain extent, so that the grinding effect of the steel bar body 104 can be more outstanding. After the grinding is completed, the air pump 121 can discharge a high-impact airflow through the nozzle 123 to clean the steel bar body 104, so that the grinding debris attached to the steel bar body 104 can be blown off, and the finishing cleaning work of the steel bar body 104 can be completed. Afterwards, the grinding wheel 108 can be used to grind and remove the larger burrs generated after the grinding of the steel bar body 104, so as to avoid subsequent injuries to the workers, which is beneficial to the actual construction work. In this process,The working of the reduction motor 111 can drive the driving gear 112 to rotate, and the driving gear 112 can use the ring tooth groove 119 to drive the mounting ring 118 to rotate, and the mounting sleeve 113 and each rotating plate 120 can be driven to rotate through the mounting ring 118, thereby driving each grinding block 114 and the grinding wheel 108 to rotate synchronously, so that the steel bar body 104 can be fully polished and cleaned, which is beneficial to actual use.
