Referring to fig. 1 to 5, a bending mechanism for steel pipe production includes a substrate 100, wherein a bending region 110 and positioning regions 120 disposed at two sides of the bending region 110 are disposed on the substrate 100. The positioning assembly 200 is assembled in the positioning area 120, and the positioning assembly 200 is used for positioning the steel pipe 400. The bending region 110 is provided with a first bending component 300 and a second bending component 310 which are oppositely arranged, a first bending channel is arranged on the opposite surface of the first bending component 300, and a second bending channel is arranged on the opposite surface of the second bending component 310; when bending, the first bending assembly 300 and the second bending assembly 310 move in opposite directions and are abutted, and the first bending channel and the second bending channel cooperate to bend the steel pipe 400.
Specifically, the positioning assembly 200 includes a positioning seat 210, and a radial positioning groove for placing the steel pipe 400 is provided on the positioning seat 210. The radial positioning groove is internally provided with an axial positioning block 220. The design of the positioning assembly 200 ensures that the steel pipe 400 can be stably supported and positioned during the bending process, thereby improving the bending precision and efficiency.
In the present invention, the first bending component 300 and the second bending component 310 are designed as separate structures, and each of the first bending component and the second bending component includes a plurality of bending press blocks that are assembled adjacently, and the bending press blocks are assembled with the substrate 100 through the guide rail 350. The bending press block is provided with grooves on opposite surfaces. When bending is carried out, adjacent grooves are matched to form a first bending channel or a second bending channel. The design disperses the bending processing of a plurality of bends of the steel pipe 400 on a plurality of bending press blocks, so that a worker can replace different bending press blocks to be suitable for different bending processes without replacing the whole first bending assembly 300 and the second bending assembly 310, thereby being beneficial to reducing the replacement cost.
In particular, the bending press blocks are divided into a driving press block 320 and a driven press block 321, the driving press block 320 is positioned in the middle of the bending zone 110, and the driven press blocks 321 are positioned at both sides of the driving press block 320. The number of the driven pressing blocks 321 is at least 2. The bottom of the driving pressing block 320 is provided with a first driving shaft 322, the first driving shaft 322 is provided with a pressing plate 330 in a sliding manner, and the pressing plate 330 is used for pushing all the driven pressing blocks 321 on the same side to move forward so as to perform bending operation. The pressing plate 330 is provided with a second driving shaft 331. The design can make the drive control of initiative briquetting 320 and driven briquetting 321 mutually independent, and initiative briquetting 320 can advance driven briquetting 321 in order to fix a position steel pipe 400 and carry out first bending, avoids initiative briquetting 320 and driven briquetting 321 to bend steel pipe 400 simultaneously when steel pipe 400 take place the skew and lead to bending the problem that does not accord with the technological requirement. The design of the pressing plate 330 can enable the driven pressing block 321 to synchronously apply force when bending, so as to ensure bending precision.
In addition, in order to further improve stability and buffering effect in the bending process, the driving pressing block 320 and the driven pressing block 321 are connected through a hysteresis buffer structure 340. The hysteresis buffer structure 340 includes a guide groove 341, a guide post 342 is fixedly assembled in the guide groove 341, a guide block 343 is slidably assembled on the guide post 342, and a buffer spring 344 is assembled between the side wall of the guide post 342 and the guide block 343, which is used for fixing the guide post 341. The structure can provide certain buffering and damping effects in the bending process, and the stability and durability of the mechanism are protected.
In addition, in order to improve the service life of the mechanism and reduce noise, the driving pressing block 320 and the driven pressing block 321 are provided with a first gasket 360 on the surface facing the pressing plate 330, and the first gasket 360 can provide proper support and buffer, so that the direct contact between the bending pressing block and the pressing plate 330 is avoided, and friction and abrasion are reduced.
The second gasket 370 is assembled in the groove, and the second gasket 370 can protect the surface of the steel pipe 400 and prevent the surface of the steel pipe 400 from being damaged by friction with the groove when the steel pipe 400 is bent and deformed.
When the bending mechanism is used, firstly, the steel pipe 400 is placed in a radial positioning groove of the positioning assembly 200, and the accurate positioning of the steel pipe 400 is ensured through the matching of the radial positioning groove and the axial positioning block 220. The steel pipe 400 is first placed in the positioning assembly 200 to achieve accurate positioning of the steel pipe 400. Then, the driving pressing block 320 of the first bending assembly 300 and the second bending assembly 310 is controlled to move forward by the driving system driving the first driving shaft 322, the steel pipe 400 is bent for the first time, the primary effect of the first bending is to position the center of the steel pipe 400, and the problem that when the driving pressing block 320 and the driven pressing block 321 bend the steel pipe 400 at the same time, the steel pipe 400 is deviated to cause bending not to meet the process requirement is avoided. Then, the second driving shaft 331 is driven by the driving system to control the pressing plates 330 of the first bending assembly 300 and the second bending assembly 310 to move forward, so as to bend the steel pipe 400 for the second time.
