Abstract

The invention discloses a U-shaped pipe landing leg punching tool, which is characterized in that a U-shaped pipe locating assembly and two side punching assemblies are arranged on the top surface of a horizontal bottom plate, wherein the side walls of a U-shaped pipe locating sleeve in the U-shaped pipe locating assembly are provided with punch via holes, the two side punching assemblies are symmetrical about the U-shaped pipe locating sleeve, a slider in each side punching assembly can slide left and right, the top surface of each slider is fixedly provided with a declivity wedge and a punch stopper, the end face, close to the U-shaped pipe locating sleeve, of each punch stopper is provided with a punch, a punching die is arranged right above the horizontal bottom plate, when the punching die downwards moves, two acclivity wedges push the two declivity wedges in the two side punching assemblies to simultaneously move towards the opposite direction, so that the two sliders can drive the two punches to simultaneously move towards the opposite direction. The U-shaped pipe landing leg punching tool can be used for well locating a U-shaped pipe and further machining holes in landing legs of the U-shaped pipe in a side punching manner, since the U-shaped pipe can be precisely located via the operation, the height error of machined holes in the two landing legs of the U-shaped pipe can be effectively eliminated.

Description

technical field [0001] The invention belongs to the field of tooling fixtures, and in particular relates to a punching tool for a leg of a U-shaped tube, through which holes are punched on two legs of a U-shaped tube. Background technique [0002] In the field of mechanical manufacturing, U-shaped pipe is a widely used pipe fitting. At present, it is often necessary to process holes on the two legs of the U-shaped pipe, and the holes on the two legs cannot have a height difference, that is, the two legs The centerlines of the upper holes must be on the same straight line. [0003] Now, often through the figure 1 The shown tooling drills holes on two legs of the U-shaped pipe, and the drilling tooling mainly consists of a positioning plate assembly 1, a first V-shaped positioning block 2, a second V-shaped positioning block 3 and a drill base 4. Wherein, a first V-shaped positioning block 2 and a drill base 4 are fixed on the top of the positioning plate assembly 1, wherein...
