Being connected by guide pillars and bushes between upper die and lower die, guide pillar connects upper mold, and guide pillar is provided with damping spring, under guide pin bushing connects
Mould, upper mold lower surface is provided with punch, and lower mold upper surface is provided with die, and punch is provided with drift, and drift includes being arranged at nose of punch
Cutting edge and the reaming mould of root, the diameter of reaming mould is more than cutting edge, by conical surface transition between reaming mould and cutting edge, at die
With the material-dropping hole that lower mold is provided with corresponding cutting edge, die is additionally provided with groove, and groove is for placing the slide bar for spacing tubing, sliding
Bar includes base, slide bar post and the circular arc clevis coordinated with groove type, and slide bar is driven by the driving means being arranged on die,
Driving means includes sensor and controller.
Further, cutting edge plane and the central axis of punch.
Further, groove is arranged on the centre of die upper surface, and groove is T font.
Further, the sealing two ends of groove.
Further, slide bar post and base by thread connect.
Further, driving means is for driving slide bar to reciprocatingly slide along groove and/or the opening or close of circular arc clevis
Degree.
Further, slide bar includes the first slide bar and the second slide bar, can drive and be clipped in circle during one of them sliding bar
Tubing in arc folder moves.
Further, cylindrical cavity is formed between material-dropping hole and die and lower mold.
By such scheme, this utility model has the advantage that
A kind of punching die of the present utility model, simple in construction, convenient processing and manufacture, low cost；By reaming mould and sword
The deformation quantity of tubing when conical surface transition between Kou reduces punching press, reduces the frictional force of punch and tubing, improves simultaneously
The Forming Quality in hole；According to practical situation, driving means controls the reciprocating motion of the slide bar of spacing tubing and circular arc clevis
Opening and closing degree, it is adaptable to the punching of the tubing of same tubing different parts and different size, improves working (machining) efficiency,
Save processing cost.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and can being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
See Fig. 1, a kind of punching die described in this utility model one preferred embodiment, including upper mold 2 and lower mold 4, on
Being connected by two guide pillars 6 and two guide pin bushings 8 between mould 2 and lower mold 4, guide pillar 6 is welded in upper mold 2, is cased with damping outside guide pillar
Spring 10, guide pin bushing 6 connects lower mold 4, and upper mold 2 lower surface is provided with punch 12, and lower mold 4 upper surface is provided with die 14, and punch 12 is provided with
Drift 16, drift 16 includes the reaming mould of cutting edge and the root being arranged at drift 16 end, and the diameter of reaming mould is more than cutting edge, sword
Mouth plane and the central axis of punch 12, by conical surface transition between reaming mould and cutting edge, be provided with on die 14 and lower mold 4
The material-dropping hole 18 of corresponding cutting edge, forms cylindrical cavity between material-dropping hole and die and lower mold, the centre of die 14 upper surface is also
It is provided with the groove 26 of T font, the sealing two ends of groove 26, in groove 26, places the slide bar for spacing tubing, sliding including first
Bar and the second slide bar, slide bar includes that the base 24 with T font, base 24 are connected, often with cylindrical slide bar post 20 by screw thread
The top of individual slide bar post 20 is respectively provided with two panels circular arc clevis 22, and slide bar is driven by the driving means being arranged on die 14, drives
Dynamic device includes sensor and controller.
Operation principle of the present utility model is as follows: be placed in circular arc clevis 22 by the tubing needing punching, sensor sense
Answer circular arc clevis 22 stress size, signal is passed to controller, controller action, adjusts the Guan Bi degree of circular arc clevis 22, from
And tubing is clamped, then stamping machine is applied in upper mold 2, makes guide pillar 6 move downward, and upper mold 2 is moved to lower mold 4, drift 16
Inserting in tubing, complete puncture motion, waste material is fallen into by material-dropping hole 18 in the container collecting waste material.When needs are on same tubing
During punching, one of them slide bar is fixed, and as the first slide bar is fixed, driving means drives the circular arc clevis 22 on the first slide bar
Open, then drive the second slide bar to slide into the next position along T font groove 26, drive and be clipped in the second slide bar circular arc clevis 22
Tubing slides, and now driving means drives the circular arc clevis 22 on the first slide bar to close, and is again clamped by tubing, punching position pair
The another one position that quasi-tubing need to punch, repeats puncture motion.The first slide bar and second can be driven to slide according to practical situation
Bar moves along groove simultaneously.According to the external diameter size of different tubing, the Guan Bi degree of circular arc clevis 22 is different, it is possible to fixing difference
The tubing of size, thus complete punching pipes, improve working (machining) efficiency, save processing cost.
The above is only preferred implementation of the present utility model, is not limited to this utility model, it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, it is also possible to do
Going out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
