The invention discloses an improved feeding roll for straightener, which comprises a plastic inner ring and a plastic outer ring. The plastic inner ring and a plastic outer ring are provided with several radially uniformly distributed connecting rods, and a reinforcing ring is also provided between the plastic inner ring and the plastic outer ring. The reinforcing ring and the connecting rod intersect and fixedly connect, and the plastic inner ring is provided with a reinforcing ring. The outer surface of the plastic outer ring is a curved surface sunken from the edge to the center. The plastic outer ring is covered with a rubber layer. A number of rubber bumps are evenly distributed on the rubber layer. The two sides of the plastic outer ring are provided with annular baffles, and the annular baffles and the plastic outer ring can be detachably connected. The invention reduces the quality and cost. The pressure of the invention on the pipe is small. Because the friction force between the rubber layer and the rubber bump is large, the friction force on the pipe is large when the pipe is pushed, and the pushing effect is good. At the same time, the scratch and indentation on the surface of the pipe are not left.
【技术实现步骤摘要】
一种改进的矫直机送料辊
本专利技术涉及矫直机领域,具体的说涉及一种改进的矫直机送料辊。
技术介绍
矫直机上的送料辊功能是将管材通过送料辊和管材之间的摩擦力推送进矫直机构内,现有技术中送料辊一般为钢及钢合金制成,送料辊和管材之间摩擦力取决于送料辊对管材的压力,对管材表面可能留下擦伤、压痕,影响管材表面质量。
技术实现思路
本专利技术为了克服上述的不足,提供了一种改进的矫直机送料辊,包括塑胶内圈和塑胶外圈,所述塑胶内圈和塑胶外圈之间设有若干径向均匀分布的连接杆,塑胶内圈和塑胶外圈之间还设有加强圈,所述加强圈和连接杆相交并固定连接,塑胶内圈内设有转动轴,塑胶内圈和转动轴过盈配合,塑胶外圈外表面为由边缘向中心凹陷的曲面,塑胶外圈外包覆橡胶层,所述橡胶层上均匀分布若干橡胶凸点,所述橡胶层和橡胶凸点为一体结构,塑胶外圈的两侧均设有环形挡板,环形挡板和塑胶外圈可拆卸连接。优选的,所述橡胶层厚度为15-25mm。优选的,所述橡胶凸点直径为5-10mm。优选的,所述挡板伸出塑胶外圈10-20mm。本专利技术的有益效果是:本专利技术结构上大大减少了钢及钢合金的用量,降低了质量,也减少了成 ...
