Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe stamping equipment, in particular to oil pipe stamping equipment with anti-bulge on both sides. Background Art

[0002] Stamping equipment is an important machine used in metal processing. It mainly applies strong pressure to metal sheets, causing them to undergo plastic deformation under the action of the mold, thereby obtaining workpieces of specific shapes and sizes. Stamping equipment can efficiently carry out large-scale production and can manufacture parts of various complex shapes. It has the advantages of high precision, high production efficiency and low cost. In the manufacturing industry, stamping equipment is widely used in automobile manufacturing, electronic equipment, aerospace and other fields, providing strong support for the development of modern industry.

[0003] In the field of automotive parts manufacturing, metal oil pipes are important fluid transmission components. Stamping equipment is used to locally change the shape of the middle part of the oil pipe to stamp out convex and concave structures. This local forming operation can adapt to specific installation spaces and meet special functional requirements. In some complex mechanical systems, in order to avoid interference between the oil pipe and other components, a concave area needs to be stamped on the oil pipe so that the oil pipe can smoothly bypass other components.

[0004] During the operation of the stamping equipment, because the outer wall of the oil pipe is round, excessive pressure may be applied to the oil pipe locally during stamping, causing the outer wall of the oil pipe to bulge. When the stamping parameters are set improperly, the pressure is too high and the stamping speed is too fast during stamping, the oil pipe will not be able to withstand the instantaneous strong force and will deform, destroying the overall structure of the oil pipe, resulting in damaged sealing of the oil pipe and leakage of fuel and lubricating oil, which not only causes waste of resources, but also pollutes the environment and even causes fire safety accidents, endangering the lives of drivers and passengers. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a double-sided anti-bulge oil pipe stamping device, which aims to improve the problem in the prior art that when stamping the oil pipe, the outer wall of the oil pipe is easily bulged and deformed due to the circular structure of the oil pipe itself.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.
