Manual tube bending machine convenient for placing wheel mould

Abstract

The invention discloses a manual tube bending machine convenient for placing a wheel mould. The manual tube bending machine comprises a workbench, wherein a tube bending mechanism is arranged on the workbench; the tube bending mechanism comprises a wheel mould mechanism; the wheel mould mechanism comprises a wheel mould body connected with the workbench; a blocking column is arranged at the outerside of the periphery of the wheel mould body; a bulge is arranged at the periphery of the wheel mould body; the bulge is connected with a handle; a tube bending matched hole is formed in the bulge; atube bending matched slot is further formed in the periphery of the wheel mould body; the tube bending matched slot and the tube bending matched hole are formed in the same medial surface, and are parallel to each other; a clamping mechanism is further arranged on the workbench; and the medial surface of the clamping mechanism is parallel to that of the wheel mould body. The manual tube bending machine has the advantages of being relatively time-saving in placing the wheel mould, and being relatively low in manufacturing cost.

Description

technical field [0001] The invention relates to a pipe bending machine, in particular to a manual pipe bending machine which is convenient for changing wheel molds. Background technique [0002] The pipe bender is a tool for bending the pipe and bending the pipe into a certain angle or arc. Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines and so on. However, the cost of CNC pipe bending machines and hydraulic pipe bending machines is relatively high. For customers who process a small number of pipe bends, the cost is too high, and it is wasteful for the machine to be idle. It is necessary to design a manual pipe bender that can adjust the bending radius that meets the needs. [0003] However, when the existing manual pipe bender bends non-standard pipes, it is necessary to replace the wheel dies with corresponding specifications. Since the existing manual pipe bender needs to replace the wheel mold, it is necessa...

Problems solved by technology

[0003] However, when the existing manual pipe bender bends non-standard pipes, it is necessary to replace the wheel mold of the corresponding specification

Since the existing manual pipe bender needs to replace the wheel mold, it is necessary to remove the wheel mold frame first, then replace the wheel mold of the required specification, and finally install the matching wheel mold frame to complete the replacement of the wheel mold, so this wheel mold The replacement method is relatively time-consuming

And because the existing manual pipe bender needs to design and manufacture a set of wheel molds with different specifications and matching wheel mold frame sets, the manufacturing cost of the existing manual pipe bender is relatively high

Therefore, the existing pipe bender has the disadvantages of time-consuming replacement of the wheel mold and high manufacturing cost.
