Background In modern industrial production, rectangular steel pipes are widely applied to numerous fields such as building structures, mechanical manufacturing, transportation and the like due to good structural strength and stability. The quality and the precision of the rectangular steel pipe play a key role in the performance and the safety of the final product, so that the steel pipe is required to be shaped in the production process, and the appearance of the steel pipe is extruded into a specified size so as to meet the requirements of practical application. Currently, there are many types of rectangular steel pipe shaping devices on the market. For example, in the prior art, a rectangular tube shaping device (bulletin number: CN 214160955U), a shaping space is formed by arranging a first roller, two second rollers and a third roller, and the first roller and the third roller are arranged in a staggered manner, and the two second rollers are arranged in a staggered manner, so that six third driving mechanisms can be started to control the movement of a lower roller shaft, a middle roller shaft and an upper roller shaft, the size of the shaping space is increased or reduced, the device is suitable for shaping rectangular tubes with different sizes, and the production cost is effectively reduced, but the prior art still has the following technical problems: 1. The rollers in the prior art are arranged in a staggered manner in space, the contact stress part of the tube and a single roller can be subjected to uneven stress in the process of being extruded by the rollers, the localized stress concentration on the surface of the tube can be caused during extrusion molding of the tube, the surface deformation is caused, and the dimensional accuracy after shaping is difficult to control. 2. Because the equipment is in long-term production process, the roller is in extrusion contact with the pipe, the forming surface of the roller can be worn, particularly the main driving roller bears active rolling force, the load is larger, the condition that the forming surface is worn into an inclined surface is more likely to occur, and the shape deviation of the pipe after shaping is larger. Disclosure of utility model The utility model provides a rectangular steel pipe shaping device, which can solve the problems that in the shaping process of a pipe by equipment in the prior art, uneven stress is easily caused on contact points of the pipe, so that surface deformation is caused, and further, the forming precision of the pipe is reduced.
