The pipe end portion upsetting device comprises a cylindrical punch located at the upper portion and a die located at the lower portion, wherein a top board is integrally formed at the top of the punch, a mandrel is integrally formed in the center of the bottom of the punch, an upsetting shaft hole and a containing shaft hole are sequentially formed in the middle of the die from top to bottom, the outer diameter of the punch is equal to the inner diameter of the upsetting shaft hole, the outer diameter of the mandrel is equal to the inner diameter of a pipe to be machined, the inner diameter of the containing shaft hole is equal to the outer diameter of the pipe to be machined, the punch is provided with a fixing board in a sleeved mode, and the edge of the fixing board is provided with a plurality of connection holes. The pipe end portion upsetting device is simple in structure, the pipe blank is formed by punching and upsetting at a time between the punch and the die, the machining efficiency is high, and the forming effect is good.

Description

Pipe end upsetting apparatus
Technical field
The utility model belongs to machining equipment technical field, relates in particular to a kind of pipe end upsetting apparatus.
Background technology
In prior art, the outside workpiece that has an axis hole for stairstepping inside carries out machine-shaping as the mode of the general employing machine toolings such as sealing shroud, outer pipe wall is circumferentially processed removal redundance.Above-mentioned processing mode general step is more loaded down with trivial details, and the pretreatment that need to carry out and parameter arrange often, and the time of machine-shaping is also long.By contrast, adopt the processing mode of drop stamping, gauge, the other end are carried out in one end of tubing and carry out the mode of jumping-up and have obvious superiority.
Utility model content
The utility model provides a kind of simple in structure, pipe end upsetting apparatus that punching press jumping-up is effective for solving the technical problem existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: pipe end upsetting apparatus comprises the punch die that is positioned at the columniform drift of top and is positioned at below, one-body molded at the top of described drift have that top board, bottom centre are one-body molded a mandrel, and the middle part of described punch die is provided with jumping-up axis hole and accommodating axis hole from top to bottom successively; The external diameter of described drift equals the internal diameter of described jumping-up axis hole, and the external diameter of described mandrel equals the internal diameter of tubing to be processed, and the internal diameter of described accommodating axis hole equals the external diameter of tubing to be processed; On described drift, be also arranged with edge with the fixed head of a plurality of connecting holes.
Advantage of the present utility model and good effect are: owing to having adopted above-mentioned design, the utility model is simple in structure.Tubing blank is the moulding of a punching press jumping-up between drift and punch die, and working (machining) efficiency is high, good forming effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model and half sectional view.
In figure: 1, fixed head; 2, top board; 3, connecting hole; 4, drift; 5, mandrel; 6, jumping-up axis hole; 7, accommodating axis hole; 8, punch die.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, the utility model comprises the columniform drift 4 that is positioned at top and the punch die 8 that is positioned at below.On drift 4, be also arranged with edge with the fixed head 1 of a plurality of connecting holes 3, for drift 4 is fixed.
One-body molded at the top of drift 4 have that top board 2, bottom centre are one-body molded a mandrel 5, and the middle part of punch die 8 is provided with jumping-up axis hole 6 and accommodating axis hole 7 from top to bottom successively.
Wherein, the external diameter of drift 4 equals the internal diameter of jumping-up axis hole 6, and the external diameter of mandrel 5 equals the internal diameter of tubing to be processed, and the internal diameter of accommodating axis hole 7 equals the external diameter of tubing to be processed.
Tubing blank after heating is positioned in accommodating axis hole 7, and drift 4 is downward, and mandrel 5 inserts in the centre bore of tubing blank, and drift 4 pushes jumping-up by the tubing blank part that is positioned at jumping-up axis hole 6 to surrounding.
