Abstract

The invention provides a combination adjustable bent pipe mould. In the prior manufacturing method, in order to bend pipes with different specifications, the pipes can be bent only by replacing corresponding fan shaped disks, but the pipe bending process has high requirement on the rigidity of the fan shaped disk, so that each replacement needs high cost. The combination adjustable bent pipe mould comprises a disk base (1), wherein the disk base (1) is provided with a module slide seat(2) provided with a hole(3); the disk base is fixedly connected with a mould block(4) by a pin; the mould block is provided with a module chute corresponding to the hole of the module slide seat; the disk base is connected with a chute(5) connected with a chute seat(6); and the disk base is connected with a fixing clamping block(7). The combination adjustable bent pipe mould is used to bend pipes in the manufacturing industry.

Description

Combined adjustable bend pipe mould

Technical field:

The present invention relates to a kind of combined adjustable bend pipe mould.

Background technology:

Traditional bend pipe production principle is that sector disk is fixed on the equipment by cross key, by the equipment driven rotary.Fixedly fixture block is installed on the sector disk with screw, forms the straight section of clamping tube.Pipe is put into fixedly fixture block die cavity, movable clip block is by the pressure of oil cylinder or the coupling mechanism force clamping tube of eccentric shaft, chute die cavity confinement tube afterbody rotates, and fixedly fixture block, movable clip block, sector disk together rotate then, realizes the pipe cold bending under the comprehensive function of mould.Traditional production method is for the bending of the pipe of different size, and we can only change corresponding sector disk and come its bending, so and well-known bend pipe process is quite high to the very high cost of changing each time of rigidity requirement of sector disk.

Therefore, design once cover low cost, high accuracy, high efficiency mould become present stage improve the manufacturing development level particularly in a main research direction of bend pipe industry level, many scholars have proposed very effective conception scheme in this regard.

Summary of the invention:

The purpose of this invention is to provide a kind of combined adjustable formula mould, changed traditional integral structure, become by base and several mould piece and form a mold jointly, solved the waste problem of sector disk.

Above-mentioned purpose realizes by following technical scheme:

Combined adjustable bend pipe mould, its composition comprises: disc base, has the module slide on the described disc base, described slide block slide has the hole, and described disc base is by the fixedly connected mould piece of pin, and described mould piece has the module chute, described module chute is corresponding with the hole on the module slide, described disc base connects chute, and described chute connects sliding chute seat, and described disc base is connected and fixed fixture block.

Described combined adjustable bend pipe mould, described module slide are 360 degree by interior circle to cylindrical and evenly distribute on described disc base, described mould piece is one group.

Beneficial effect of the present invention:

In today that mechanical industry develops rapidly, bend pipe is as an important link of manufacturing industry, quality and the cost of merely pursuing bend pipe have not satisfied the flourish needs of manufacturing industry gradually, the desired most important except quality and cost of present machinery manufacturing industry is exactly a production efficiency, the cost of metal industry is than higher as everybody knows, with the bent tube technique is example, the cost of a medium-sized pipe just approximately reaches units up to ten thousand, if mistake in BENDING PROCESS, occurs, off quality, pipe just becomes waste product so, so in actual production processing, we can place the quality of pipe above the other things, this has also caused our processing steps that can slow down in processing in the past, especially in the production of mould, select even on the clamping of mould, all can spend a large amount of time, adding now, our employed mould all is the corresponding pipe of a kind of specification mould object, though this production method can be protected qualitatively bend pipe, but in the processing of mould, consumed a large amount of design production times, reduced bend pipe production efficiency virtually, in addition in small batch is produced every suit mould after use, almost become waste product, so just brought additional cost to process.

The combined type bend pipe mould of our design mainly is to have carried out combination to improve in traditional bend pipe mould, mainly is applicable to tube bending and small batch production that caliber is less.Compared with the prior art, its major advantage is can be in the caliber of a mould adjusted bend pipe mould and the demand of angle of bend, often avoid the more loaded down with trivial details process of mold exchange and saved most of fund that mould is produced, briefly exactly can by regulate above the assembling die the slip tube seat and more the mold exchange piece play to different tube diameters and differently curved radius require satisfied, not only often saved more mold exchange loaded down with trivial details process but also improved the utilization rate problem of mould, saved cost greatly, particularly suitable in small batch is produced.Can save a large amount of grinding tool expenses, and then reduce cost, improve the performance of enterprises.

The specific embodiment:

Embodiment 1:

Combined adjustable bend pipe mould, its composition comprises: disc base 1, has module slide 2 on the described disc base, described slide block slide has hole 3, and described disc base is by the fixedly connected mould piece 4 of pin, and described mould piece has the module chute, described module chute is corresponding with the hole on the module slide, described disc base connects chute 5, and described chute connects sliding chute seat 6, and described disc base is connected and fixed fixture block 7.

Embodiment 2:

Embodiment 1 described combined adjustable bend pipe mould is by a disc base 1, chute 5, sliding chute seat 6 and several mould piece 4 are formed, the quantity of movable mould piece and big I are changed and are regulated according to the pipe situation that will produce, chute is the same with traditional chute effect to have played the effect that tail pushes away, different is that it can be according to size move left and right and replacing on sliding chute seat of caliber, to adapt to the demand of different tube diameters, and chute still designs according to the reversible deformation principle, promptly the resilience principle according to tube bending is designed to oval groove face to mould, each little mould piece is made up of similar fan-shaped ring structure, mould block structure such as Fig. 3, shown in Figure 4, it has added again except his shape with the different place of traditional sector disk can be at a chute of disc base slip, we just can select the flexible mould piece according to the data of pipe behind selected certain pipe, be fixed on the disc base with pin then, the core of combined adjustable mould is exactly these little mould pieces, its operation principle is exactly after the model of pipe is fixing, just according to the size of caliber select the to vary in size mould piece of specification, certainly these mould pieces all are to make in advance well, its manufacturer's standard just is used as standard according to the hole above the chute of disc base, in order to guarantee rigidity, produced each group mould piece all will closely connect after on clamping, not so may bear the incessantly powerful bending force of BENDING PROCESS, be can be customized according to the needs oneself of each producer in these holes of disc base certainly.That is to say if this producer generally only processes three kinds of specification pipes and so just can only make the little mould piece of three covers, so only need on disc base, process three row's circular holes and get final product according to the data of these three kinds of pipes.So both saved complicated procedures of forming and the expense in the manufacture process, and can on a mould, process the pipe of three kinds of specifications, when the little mould piece that changes from a kind of pipe above only need changing when doing to process another pipe, save trouble and convenient and swift, middle-size and small-size workman of pipe just can easy manipulation.

Introduce the structure of disc base at last, it is the disk that has chute above, in order to satisfy rigidity requirement, should select foundry goods for use, by the shape of mould piece as can be known, chute is a T shape structure, and the mould piece can slide in the above, make things convenient for the replacing of mould piece like this, the hole above the chute is designed for the fixed mould piece.And the crooked power of whole combined adjustable mould still adopts traditional roll extrusion mode to carry out.This combined adjustable mould brings very big economic worth can for after dropping into actual production bend pipe industry, wishes that also more designer can put into how better design in the actual production of our mechanical industry.
