Abstract

The invention relates to a four-shaft horizontal forming and bending machine for machining a corrugated culvert pipe. The four-shaft horizontal forming and bending machine is characterized in that a driving shaft A is installed on a left reducer, a driving shaft B is installed on a right reducer, a lifting fulcrum is arranged in the center of the top end of a lifting bracket arranged on the ground located on one side of the left reducer, and a driven forming shaft is arranged on a driven forming shaft head installed at the bottom of the lifting fulcrum; a tensile force frame is arranged in the center of a housing frame, a recoil preventing hydraulic oil cylinder A is installed at the bottom of the tensile force frame, and a round steel plug pin is arranged at the top of the tensile force frame; two recoil preventing hydraulic oil cylinders B are arranged on a base of the forming and bending machine and provided with forming shafts; the inner diameter of right side end wheels of the forming shafts is 16 mm wider than that of left side end wheels; and the outer side of an anti-abrasion nylon sleeve of the driven forming shaft is sleeved with a forming wheel. The four-shaft horizontal forming and bending machine has the beneficial effects that the error of the product produced by the machine is decreased, the product quality is improved, the working efficiency is high, the machining cost of the pipe is reduced, and the profit margin is increased.

Description

technical field [0001] The invention relates to the field of metal products industry, and relates to a production method for replacing reinforced concrete bridges and culverts of railways and highways, as well as reinforced pipes for bridges and tunnels, in particular to a four-axis horizontal integrated corrugated culvert pipe bending machine. Background technique [0002] The diameter error of the product produced by the existing culvert pipe manufacturing equipment is ±3cm, and the wave height error is ±3mm. The flange can be formed and used after welding and grinding. The labor cost is high, which indirectly results in low work efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a four-axis horizontal fully-packed corrugated culvert tube bending machine. The technical solution adopted by the present invention to solve the technical problem is: the four-ax...
