Description

Pipe fitting floating punch punch die

Technical field

This utility model belongs to machined die technical field, more specifically, it relates to a kind of pipe fitting floating punch punch die.

Background technology

At present, it is to be injected in core rod by blank pipe part that the blank pipe part such as side of steel pipe, copper pipe etc. is processed the method for side opening, then with drift punching, wherein, core rod is arranged and dodges hole and make drift pass through.But, the method typically can only process the side opening that aperture is less, and as aperture is slightly larger, then blank pipe wall is easily deformed, and especially for the pipe fitting of lateral symmetry punching, its crudy is the most worse.

Utility model content

The purpose of this utility model is to provide a kind of pipe fitting floating punch punch die, solves the technical problem of existing blank pipe punching quality difference, to overcome the deficiency in the presence of prior art.

The technical scheme in the invention for solving the technical problem is: pipe fitting floating punch punch die, on including, die shoe, on, lower bolster, on, lower bolster, also include loading and unloading material plate, lower stripper, on, lower stripper is respectively placed in, between lower bolster, upper, float between lower stripper and die socket is set, die socket is built-in with die, square tube can be inserted to die and make die stretch in square tube, drift it is provided with over and under at die, die is provided with through hole, at the through hole two ends of die, floating upper mold core is set, floating lower mold core, some spring eyes are set in floating lower mold core, spring eye interpolation shock mount hook.

It is provided with guide pin bushing and guide pillar between described upper and lower die holder.

Arranging cylinder block and ejection block in the side of die socket, cylinder can promote ejection block to be inserted in square tube.

Arranging little guide pin bushing in described die socket, little guide pillar slides in little guide pin bushing, and the top of little guide pillar connects limited block.

Between described lower stripper and die shoe, discharging screw is set, sheathed brute spring on discharging screw.

Between described loading and unloading material plate and upper bolster, discharging screw is set, sheathed brute spring on discharging screw.

Support spring is set between described lower bolster and die socket.

The beneficial effects of the utility model are:

After have employed the scheme of float mould core punching, the profile of die is adaptive with blank pipe, and punch process die floats with drift, alleviates the impact to blank pipe, makes punching operation quality be greatly improved, and the drift life-span is extended.

In floating lower mold core, carbine is set, makes punched scrap be held up by carbine, then pushed away the via of core rod by material jacking mechanism, it is to avoid fall to damage low punch under punched scrap.

Detailed description of the invention

Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, and the most same or similar label represents same or similar element or has the element of same or like function.The embodiment described below with reference to accompanying drawing is exemplary, is only used for explaining this utility model, and it is not intended that to restriction of the present utility model.

In description of the present utility model, it will be appreciated that, term " " center ", " laterally ", " on ", D score, "left", "right", " vertically ", " level ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship; be for only for ease of description this utility model and simplifying and describe; rather than instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance or the implicit quantity indicating indicated technical characteristic.Thus, define " first ", one or more this feature can be expressed or impliedly be comprised to the feature of " second ".In description of the present utility model, except as otherwise noted, " multiple " are meant that two or more.

In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " is installed ", " being connected ", " connection " should broadly understood, and connects for example, it may be fixing.Can also be to removably connect, or be integrally connected；Can be to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can understand that above-mentioned term is at concrete meaning of the present utility model with concrete condition.

As Figure 1-4, pipe fitting be cross section be the square tube of rectangle, need to symmetrical punching on upper lower wall surface.Floating punch punch die includes upper bolster 13, die shoe 5, upper padding plate 12, lower bolster 6, cope match-plate pattern 11, lower bolster 7, also include loading and unloading material plate 10, lower stripper 8, upper and lower stripper is respectively placed between upper and lower template, float between upper and lower stripper and die socket 1 is set, die socket is built-in with die 9, die 9 is provided with the through hole dodging upper and lower round punch, upper and lower end at through hole is respectively arranged with floating upper mold core 26, floating lower mold core 27, and square tube can be inserted to die and make die stretch in square tube, is provided with round punch 15 over and under at die.

Guide pin bushing 16 and guide pillar 17 it is provided with between upper and lower die holder.Arranging little guide pin bushing 19 in die socket 1, little guide pillar 20 slides in little guide pin bushing 19, and the top of little guide pillar 20 connects limited block 18.Owing to being provided with limited block 18, make the stroke that fluctuates of die socket limit, die rebound too can be prevented high and depart from from die socket and come.Between lower stripper 8 and die shoe 5, discharging screw 4 is set, sheathed brute spring on discharging screw.Meanwhile, between loading and unloading material plate and upper bolster, it is also provided with discharging screw 4, same sheathed brute spring on discharging screw.Support spring 21 is set between lower bolster 7 and die socket 1.

The oral area internal diameter of floating lower mold core is less than main wall portion internal diameter, and, the oral area surrounding in floating lower mold core is uniformly arranged four spring eyes 28, and spring eye interpolation shock mount hook 29, the coupler body of carbine 29 freely stretches in the through hole of floating lower mold core.Arrange cylinder block 3 and ejection block 2 in the side of die socket 1, cylinder can promote ejection block to be inserted in square tube.During punching, punch press makes the round punch 15 on cope match-plate pattern 11 impact downwards square tube, under powerful momentum effect, die socket, the square tube being enclosed within fovea superior die holder are descending with round punch, the round punch being press directly against on lower bolster, the punching on the upper and lower wall of square tube of two drifts, waste material moves with round punch, when round punch resets, the coupler body elasticity of carbine 29 is opened, punched scrap is held up by four coupler bodies, is then extend in the through hole of die (passageway arranging ejection block in die) by ejection block, punched scrap is pushed away die.

Embodiment the most of the present utility model; it will be understood by those within the art that: in the case of without departing from principle of the present utility model and objective, these embodiments can be carried out multiple change, revise, replace and modification; scope of the present utility model is limited by claim and equivalent thereof; without creative work improvements introduced etc., within should be included in protection domain of the present utility model.
