1, by bending, shaping influence, pipe port is irregular, not rounding, cannot assemble by hand, cannot use.If 2 design, process special mouth of pipe shaping tooling, the manufacturing cycle is longer and manufacturing cost is too high, cannot meet the requirement for delivery of high efficiency, low cost.
Summary of the invention
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, processing, simple and easy stainless steel mouth of pipe apparatus for shaping easy to use, this device can ensure the assembling instructions for use of manual exemplar, greatly reduces manufacturing cost, meets the exemplar demand of paying fast.
For solving the problem, the utility model adopts following technical scheme:
A kind of simple and easy stainless steel mouth of pipe apparatus for shaping, it has a punch and a die, forming surface between punch and die is respectively equipped with mutually corresponding semi-circular recesses, the semi-circular recesses of punch and die is combined into a circular vestibule, for realizing the shaping of the stainless steel mouth of pipe; Forming surface between punch and die is respectively equipped with the trapezoid boss cooperatively interacted and trapezoidal groove, and described semi-circular recesses is located at the middle part of trapezoid boss and trapezoidal groove respectively.
Preferably, described punch and die are arranged up and down.
Preferably, after described punch and die matched moulds, profile is a cylinder, so that process and improve the matched moulds angle of punch and die.
Preferably, be respectively equipped with a plane in punch upper end and die lower end, so that the placement of punch and die and matched moulds, shaping operation.
Preferably, the vertical height of described trapezoid boss is less than the vertical depth of trapezoidal groove.
Preferably, the gap between the upper surface of described trapezoid boss and the inner bottom surface of trapezoidal groove is 0.1-1mm.
Preferably, the plane of punch upper end and die lower end is respectively equipped with screw, so that install.
Preferably, be also provided with a punch die, punch die is ladder shaft-like, and the diameter of axle and the internal diameter matched in clearance treating the shaping mouth of pipe of punch die path one end, to realize the shaping treating shaping internal wall of pipe orifice.
The beneficial effects of the utility model are:
1, owing to the forming surface between punch and die being respectively equipped with the trapezoid boss and trapezoidal groove that cooperatively interact, therefore, it is possible to ensure the closing precision of punch and die, ensure that pipe fitting there will not be folder rib when clamping, shaping.
2, structure is simple, processing, easy to use, and machining accuracy is high, low cost of manufacture; Versatility is good, can meet assembling, instructions for use, greatly reduce manufacturing cost after the simple shaping of the stainless steel exemplar mouth of pipe in automobile egr system assembly, meets the exemplar demand of paying fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view after Fig. 1 removes punch die.
In figure: die 1, trapezoidal groove 101, plane 102, punch 2, trapezoid boss 201, plane 202, semi-circular recesses 3, screw 4, punch die 5, pipe fitting 6.
Detailed description of the invention
As shown in the figure, the one that the utility model relates to simple and easy stainless steel mouth of pipe apparatus for shaping, comprise a punch 2 and a die 1, mutually corresponding semi-circular recesses 3 is respectively equipped with in the middle part of forming surface between punch 2 and die 1, punch 2 is combined into a circular vestibule, for realizing the shaping of the stainless steel mouth of pipe with the semi-circular recesses 3 of die 1.Forming surface between punch 2 and die 1 is respectively equipped with the trapezoid boss 201 and trapezoidal groove 101 that cooperatively interact, described trapezoid boss 201 is inserted in trapezoidal groove 101, the vertical height of described trapezoid boss 201 is less than the vertical depth of trapezoidal groove 101, namely a gap is left between the upper surface of trapezoid boss 201 and the inner bottom surface of trapezoidal groove 101, as preferably, described gap is 0.1-1mm.The semi-circular recesses 3 of described punch 2 and die 1 is located on trapezoid boss 201 and middle part in trapezoidal groove 101 respectively.
As preferably, described punch 2 and die about 1 are arranged.
As preferably, after described punch 2 and die 1 matched moulds, profile is a cylinder, so that process and improve the matched moulds angle of punch 2 and die 1.Be provided with a plane 202 in punch 2 upper end, be provided with a plane 102 in die 1 lower end, so that the placement of punch 2 and die 1 and matched moulds, shaping operation.The plane 102 of the plane 202 in punch 2 upper end and die 1 lower end is respectively equipped with vertically two screws 4, for realizing the installation of punch 2 and die 1.
