Description
Technical field
The utility model is related to a kind of molds.Specifically, be for by the punching processing on the upper wall of small-bore flat tube into
The molding die of hole flanging.It is particularly suitable on the fuel gas inlet interface flat tube upper wall of the gas-cooker in caravan etc small space
Hole flanging processing.
Background technology
It is both known about in caravan production industry, the gas-cooker for cooking for occupant is fitted in caravan.Due to caravan
Interior space is smaller, and the bore for being used for the pipe fitting --- -- flat tube for installing gas inlet valve on gas-cooker is also very small.Wherein
Flat tube contain there are two the tube wall that is mutually parallel and two arc tube walls positioned opposite, process and be used as on one arc tube wall
The hole flanging of air inlet during installation, is machined with internal thread, in order to install air intake valve in hole flanging.Process the conventional method of hole flanging
It is the taper bit of high-speed rotation and flat tube mantle friction heat softening flat tube bore area to be bored using hot melt, from one of flat tube
Ecto-entad drills on the outside of arc tube wall.While taper hot melting drill head drills, the surrounding in drilled hole is softened and is formed
One outside thrust so as to form the outward flanging with certain altitude in the surrounding edge in drilled hole, realizes hole flanging
Processing.For the sake of anti-corrosion and beauty, flat tube used is usually all using galvanized pipe, and zinc coat fusing point thereon is low, such as
Fruit is drilled with taper hot melting drill head, and acutely chemical reaction occurs at high temperature with the oxygen in air for the zinc coat in hole flanging area, goes out
Existing combustion phenomena, reaction product zinc oxide is squeezed into hole wall steel matrix or residual hole wall surface, easily causes hole flanging mouth
Crack at edge or cell wall rupture while Zinc coat is destroyed, seriously affect the quality and yield rate of hole flanging.For this purpose,
First the zinc coat of the hole flanging surrounding of flat tube to be processed need to just be removed with acid washing method before hole flanging processing, then it is hot with taper
Molten bit bore.To extend the service life of flat tube, in hole flanging process finishing, also need to plate the corresponding site of flat tube again
Zinc.It can be seen that processing hole flanging using the above method, step is more, complex process, and production cost is higher.In addition, using hot melt
Drill bit is low to process the flange height that hole flanging is formed, and the screw thread lines of the tapping in a lower height of flange is short, it is difficult to meet
The installation of valve needs.Due to processing hole flanging using hot melting drill head, the flange thickness formed is difficult to control so that flange is thick
Spend relatively thin, not only intensity is low, but also flange is easily broken during tapping, high rejection rate.
Utility model content
Problem to be solved in the utility model is to provide a kind of small-bore pipe hole-flanging device.Using this device come in osculum
Hole flanging is processed on the flat tube of footpath, not only step is few, simple for process, production cost is low, but also the flange thickness of the hole flanging processed compared with
It is thick, intensity is high, when tapping is not easy to break through, rejection rate is low.
The above problem to be solved in the utility model is realized by following technical scheme：
As can be seen from the above scheme, since the utility model contains U-shaped seat, U-shaped seat is interior, and there are two gripping block, two clampings
There is longitudinal fluting on the top proximal surface of block, the flat slot for accommodating flat tube is made of two longitudinal flutings.It is useful for compressing in U-shaped seat
The cavity plate of gripping block, cavity plate top are connected with press.There are longitudinal shallow slot, the slot bottom of longitudinal shallow slot and flat slot in the centre of cavity plate lower surface
Slot bottom be arc, the flat hole being adapted to flat tube is formed by longitudinal shallow slot and flat slot, when work is processed flat tube and is placed in flat hole
It is interior, there is punching on flat tube upper side, there is die orifice hole on the cavity plate opposite with punching.Fixed block, two gripping blocks are connected with behind U-shaped seat
There is plug between fixed block, plug rear end is fixed in fixed block, and plug front end is penetrated in the processed flat tube in flat slot.With mould
Have vertical hole on the upside of the corresponding plug of oral pore, there is first longitudinal direction hole in the plug between vertical hole and plug rear end, and vertical hole with
Excessive in streamlined circular arc between first longitudinal direction hole, the diameter in vertical hole and first longitudinal direction hole is equal, and vertical hole or first longitudinal direction
Twice of the diameter difference in hole and die orifice hole≤processed flat tube thickness；Be connected with behind fixed block into pearl seat, into pearl seat on have and the
The second longitudinal direction hole of one longitudinal hole connection.Have above into pearl seat communicated with second longitudinal direction hole into the hole of bead.First longitudinal direction has in hole
Mandril, mandril outer end are connected with cylinder.
During work, entrance is passed sequentially through into first longitudinal direction hole, vertical hole into the steel ball in the hole of bead using mandril and is indulged with first
Streamlined circular arc transition zone and vertical hole between hole, finally make steel ball be ejected out of vertical hole, only need a step, are achieved that flat
The flange processing of punching on pipe, compared with background technology, step is few, simple for process, and production cost is low.Again due to the utility model
It will be justified using mandril into the streamlined passed sequentially through into the steel ball in the hole of bead between first longitudinal direction hole, vertical hole and first longitudinal direction hole
Arc transition zone and vertical hole, finally make steel ball be ejected out of vertical hole, and the ecto-entad for becoming traditional is processed as processing from inside to outside,
The equipment such as taper hot melting drill head are not required to, the flange height formed is high, and the screw thread lines of the tapping in higher-height flange is long,
The installation needs of valve can be met.Hole flanging is processed due to not having to hot melting drill head, the flange thickness formed is substantially with being processed
The pipe thickness of flat tube is identical, and thickness is thicker, and intensity is higher.Again by the flange thickness and the tube wall of processed flat tube that are formed
Thickness is essentially identical, and what flange was easily broken when avoiding tapping happens, and thus greatly reduces rejection rate.
