It is high.Also, in traditional processing, hole position processing for specific location on pipe, it is necessary on pipe marking, then to shining into
Row drilling, precision are low.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of equipped with size positions reference, rotatable tubular and carries out
The high accuracy circular pipe perforating die of circumferential punching.
Technical solution is used by the utility model solves its technical problem：A kind of high accuracy circular pipe perforating die, bag
Include：
Die holder, the die holder upper end are equipped with the groove being adapted to pipe outer contour；
Cavity plate, the cavity plate are the circular stock being adapted with round tube inside diameter, and cavity plate is arranged on along groove length direction level
Above groove, during so that pipe is plugged on cavity plate, lower end fitting groove, cavity plate upper end edge is axially arranged with blowpit, cavity plate
End, which is equipped with, rotates reference circle, for the reference of pipe rotational angle；
Upper mold seat, the axial direction of lower face along the cavity plate of the upper mold seat are provided with sliding slot, are inserted on the outside of the sliding slot with pipe
The first insertion end being connected on cavity plate is equipped with slide scale for zero point；
Punch-pin, the punch-pin are slidably mounted in sliding slot, its lower end corresponds to blowpit and is equipped with punch, is corresponded on punch-pin
The axis of punch is equipped with a sliding pointer, and the indication end of the sliding pointer is arranged on the outside of slide scale, for the cunning of punch-pin
Move apart from reference.
Preferably, the punch sets one to be used to form the taper that lower end is big, upper end is small.
Preferably, some jacking blocks are equipped with the blowpit, the jacking block upper surface matches with cavity plate outer surface, with
Punching position is formed for being bonded round tube inner wall, and by two jacking blocks separated.
The beneficial effects of the utility model are：First, the cavity plate being plugged in pipe is set, pipe can be avoided in punching
Integrally flattened in journey；Second, punch-pin is slidably set, and is correspondingly arranged blowpit on cavity plate, it can be achieved that the hole position of diverse location
Processing；3rd, upper mold seat sets slip reference of the slide scale for punch-pin, is set on cavity plate and rotates reference circle for pipe
Rotate with reference to, it can be achieved that the precise positioning of processing hole position, machining accuracy higher.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is the structure diagram of the utility model.
Embodiment
With reference to Fig. 1, the utility model is a kind of high accuracy circular pipe perforating die, including：
Die holder 3,3 upper end of die holder are equipped with the groove being adapted to pipe outer contour；
Cavity plate 4, the cavity plate 4 are the circular stock being adapted with round tube inside diameter, and cavity plate 4 is set along groove length direction level
Above groove, during so that pipe is plugged on cavity plate 4, lower end fitting groove, 4 upper end edge of cavity plate is axially arranged with blowpit, recessed
The end of mould 4, which is equipped with, rotates reference circle, for the reference of pipe rotational angle；
Upper mold seat 1, the axial direction of lower face along the cavity plate 4 of the upper mold seat 1 are provided with sliding slot, and the sliding slot outside is with pipe
The first insertion end being plugged on cavity plate 4 is equipped with slide scale 11 for zero point；
Punch-pin 2, the punch-pin 2 are slidably mounted in sliding slot, its lower end corresponds to blowpit and is equipped with punch 21, punch-pin 2
The axis of upper corresponding punch 21 is equipped with a sliding pointer, and the indication end of the sliding pointer is arranged on the outside of slide scale 11, with
In the sliding distance reference of punch-pin 2.
In order to reduce the abjection resistance that back punching head is completed in punching, the punch 21 set one to be used to being formed lower end is big, upper end
Small taper.Preferably 1 ° to 5 ° of the taper.And the slip positioning of punch-pin 2, it can come in one lock-screw of setting outside the side wall of sliding slot
The part that is matched with sliding slot of locking punch-pin 2 or in setting lock-screw on punch-pin 2 come between locking on the outside of punch-pin 2 and sliding slot
Relative position.
When and hole position relatively thin in tube wall sets larger, above-mentioned punching pattern also brings along certain tube wall deformation, because
Some jacking blocks are equipped with blowpit described in this present embodiment, the jacking block upper surface matches with 4 outer surface of cavity plate, for patch
Round tube inner wall is closed, and punching positions are formed by two jacking blocks that separate, the above problem is overcome with this.
Using the punching die of the present embodiment, pipe to be processed is inserted into from the left end (direction as shown, similarly hereinafter) of cavity plate 4
To the dead-center position of the right part of cavity plate 4, i.e. slide scale 11, then move punch-pin 2 to setting machining position and be punched out processing.If
It is when needing circumferential hole position processing, rotates the standardized line of reference in one end of reference circle in close on circular tube external wall, then compare rotation point
Degree circle rotates pipe to predetermined angular and is punched out.If light wall pipe is processed, then before pipe is inserted into, in corresponding on cavity plate 4
Predetermined hole position place one jacking block of left and right ends placement, then be processed by above-mentioned steps.
A kind of high accuracy circular pipe perforating die of the present embodiment, first, the cavity plate 4 being plugged in pipe is set, can be avoided
Pipe integrally flattens in punch process；Second, punch-pin 2 is slidably set, and be correspondingly arranged blowpit on cavity plate 4, it can be achieved that
The hole position processing of diverse location；3rd, upper mold seat 1 sets slip reference of the slide scale 11 for punch-pin 2, is set on cavity plate 4
Rotate reference circle and be used for the rotation of pipe with reference to, it can be achieved that the precise positioning of processing hole position, machining accuracy higher.Overall structure letter
It is single, it is highly practical.
Above-described embodiment is the preferred solution of the utility model, and the utility model can also have other embodiments.Ability
The technical staff in domain can also make equivalent variations or replacement on the premise of without prejudice to the utility model spirit, these equivalent changes
Type or replacement are all contained in the scope set by the application claim.
