A pipe notch-flanging press according to an embodiment of the present invention is described below with reference to fig. 1 to 7.

The pipe notch flanging press according to the embodiment of the utility model, as shown in fig. 1 to 7, comprises:

the base 100, the top of the base 100 is provided with a mounting seat 101 and a mounting frame 102;

the positioning column 200 is horizontally arranged on one side of the mounting seat 101, the upper end of the positioning column 200 is horizontally provided with a mounting surface 201, the mounting surface 201 is provided with a lower die 202, the edge of the mounting surface 201 is positioned outside the outer side wall of the lower die 202, and the positioning column 200 is used for sleeving the pipe 400 and enabling the lower die 202 to be positioned in the pipe 400;

go up mould 300, can set up on mounting bracket 102 with going up and down, the bottom of going up mould 300 is provided with recess 301, goes up mould 300 decline in-process, and lower mould 202 can stretch into in the recess 301 to the clearance of setting for the distance is reserved between the lateral wall of lower mould 202 and the inside wall of recess 301.

In this embodiment, when the surrounding portion of the notch of the tube 400 needs to be flanged, the end of the tube 400 with the notch is sleeved on the positioning column 200, and the notch of the tube 400 is upward, while the edges of the notch are positioned right above the lower mold 202, and then the upper mold 300 is moved downward, when the upper die 300 moves to a set position, the bottom end of the upper die 300 can be attached to the position around the notch of the pipe 400, which is a set distance away from the edge of the notch, and then the upper die 300 is continuously moved downwards, so that the lower die 202 can extend into the groove 301, that is, the upper die 300 can be sleeved outside the lower die 202, in the process, the pipe 400 is folded at the position between the edge position of the notch and the position where the pipe 400 is attached to the bottom end of the upper die 300, and is positioned in a gap between the outer sidewall of the lower mold 202 and the inner sidewall of the groove 301, thereby forming a burring, and after the burring is completed, the upper mold 300 is moved upward, and then the pipe 400 is pulled away from one end of the positioning column 200 far away from the mounting seat 101. According to the pipe notch flanging punch press provided by the embodiment of the utility model, when the peripheral part of the notch of the pipe 400 needs to be flanged, the operation is simple, the time and the labor are saved, and the flanging quality is better compared with the manual flanging.

It should be noted that, the positioning column 200 is horizontally disposed on one side of the mounting seat 101, which means that one end of the positioning column 200 is connected to the mounting seat 101, the positioning column 200 is entirely located on one side of the mounting seat 101, and an axial direction of the positioning column 200 is a horizontal direction, so as to conveniently sleeve the pipe 400. The upper end of the positioning column 200 is horizontally provided with an installation surface 201, a partial structure can be cut off at the top end of the positioning column 200 to form the installation surface 201, the installation surface 201 can also be integrally formed with the positioning column 200, and only the installation surface 201 needs to be horizontally arranged. The length direction of installation face 201 can be followed reference column 200's axial extension, and the both sides of installation face 201 length direction can extend to the lateral wall of reference column 200, and the one end that installation face 201 kept away from mount pad 101 can extend to the terminal surface of the one end that reference column 200 kept away from mount pad 101 to the position turns over around of the breach of mould 300 to tubular product 400 is gone up in the convenient cooperation. The length direction of lower mould 202 can be along the axial extension of reference column 200, and the border of installation face 201 is located outside the lateral wall of lower mould 202, and in the vertical direction that is, the projection of lower mould 202 lateral wall is located the inside of the projection at installation face 201 border to the position is turned over around the breach of tubular product 400 is conveniently gone up in the cooperation of mould 300. After reference column 200 is established to tubular product 400 cover, lower mould 202 is located tubular product 400, in order to carry out the turn-ups to the position around the breach of tubular product 400, the border of the breach of tubular product 400 need be located lower mould 202 directly over, that is to say in vertical direction, the projection at the border of the breach of tubular product 400 is located the inside of the projection of lower mould 202 lateral wall, only under this kind of condition, when going up mould 300 and descending, just can act on the position around the breach of tubular product 400, thereby realize the turn-ups. A gap with a set distance is reserved between the outer side wall of the lower die 202 and the inner side wall of the groove 301, and the gap can be slightly larger than the thickness of the pipe 400, so that the influence on the surrounding part of the notch of the pipe 400 caused by the undersize or oversize gap is avoided.
