Description

A kind of adjustable type eccentric reducing Taper Pipe lock molding die

Technical field

This application involves the manufacturing technology field of airplane parts, especially a kind of lock of eccentric reducing Taper Pipe part is molded Mold.

Background technique

In the development process of novel aircraft number, there are a large amount of Taper Pipe parts, structure is eccentric reducing tube shape, variable taper 2~20 ° of degree, 100~400mm of bus length.Current such part forming does not have special tooling, is to borrow to produce conventional round tube The lock compression mould of part is formed.Since the maximum difficult point of such part forming is caliber consecutive variations and bias, own Bus it is different in size.So need to increase corresponding auxiliary element to mold when borrow round tube lock compression mould carrys out formation of parts, It also needs to continuously adjust the operating attitude of mold at work, it is required successive when adapting to Taper Pipe forming parts Movement it is compound.This depends greatly on the operative skill and experience of worker, requires the technical capability of worker very high.Pass through This mode forming part, production efficiency is low, and Forming Quality is unstable, does not adapt to the accurate fast of new model airplane parts completely Speed manufacture requires.

In addition, since such part size specification, quantity are more, a kind of traditionally method, the part of specification is needed Corresponding one set of die, if design specialized mold, tooling quantity is excessive, and the production cost is very high.It is therefore desirable to consider a kind of operation Simply, wide, the adaptable universal mold of adjustable range is molded come the lock for solving eccentric reducing Taper Pipe part.

Summary of the invention

The purpose of the application is to provide a kind of general lock compression mould of adjustable type eccentric reducing Taper Pipe, may be implemented to permit lathe Perhaps the eccentric reducing Taper Pipe part high quality, high efficiency of arbitrary dimension, the lock of low cost are molded in range.

To achieve the above objectives, the application, which adopts the following technical scheme that, is achieved:

A kind of general lock molding die of adjustable type eccentric reducing Taper Pipe, including upper die component, lower mold assemblies, wedge-shaped machine Structure；Upper die component includes punch-pin fixing seat and lock belling mould, and punch-pin fixing seat top is tight by machine tool fixture with lathe top shoe It is solidly connected, bottom is equipped with the holding tank of perforation, and lock belling mould and holding tank are coupled use, and one end is fixed, and the other end can be It is moved up and down in holding tank, the punch-pin fixing seat outer end face of lock belling mould movable terminal is equipped with high scale line；Lower mold assemblies packet Lower die holder, left module, right mould block, spring are included, lower die holder is placed in the guide groove in the lower table face of lathe and presss from both sides by lathe Tool is connected and fixed, and lower die holder length direction is equipped with wedge block guide groove, and width direction is equipped with symmetrical oblong slots, left module Be mounted on the upper surface of lower die holder with right mould block and one end be mounted in oblong slots, lower die holder be equipped with lower graduation mark, 0 point For the lateral surface of left and right module, spring is fixed on the inside of left and right module one end；Wedge mechanism includes wedge block and adjusting spiral shell Bar, wedge block are mounted in guide groove, and adjusting screw rod pushes wedge block to move between the module of left and right along guide groove, push left and right Module moves in oblong slots.

The application utilizes profiling molding and punching press principle, realizes and becomes size eccentric reducing Taper Pipe part quickly and effectively lock It is molded, it is molded to eccentric reducing Taper Pipe lock that there is general applicability.

Attached drawing is described in further detail this application with reference to embodiments.

Specific embodiment

Referring to FIG. 1 to FIG. 2, woollen 1 is unfolded before eccentric reducing Taper Pipe part lock is molded, shape is trapezoidal plate；Lock It is taper tube components 2 after molded.In a particular application, trapezoidal plate expansion woollen lock is molded for eccentric reducing Taper Pipe zero Part.

Referring to Fig. 3~Fig. 8, a kind of general lock molding die of adjustable type eccentric reducing Taper Pipe, including upper die component 3, under Membrane module 4, wedge mechanism 5；Upper die component 3 includes punch-pin fixing seat 7 and lock belling mould 9, on 7 top of punch-pin fixing seat and lathe Sliding block is fastenedly connected by machine tool fixture, and bottom is equipped with the holding tank 8 of perforation, and lock belling mould 9 is coupled with holding tank 8 to be made With one end is fixed, and the other end can move up and down in holding tank 8,7 outer end face of punch-pin fixing seat of 9 movable terminal of lock belling mould It is equipped with high scale line 6；Lower mold assemblies 4 include lower die holder 10, left module 11, right mould block 12, spring 13, and lower die holder 10 is placed on It is connected and fixed in the guide groove in the lower table face of lathe and by machine tool fixture, 10 length direction of lower die holder is led equipped with wedge block To slot 16, width direction is equipped with symmetrical oblong slots, and left module 11 and right mould block 12 are mounted on the upper surface of lower die holder 10 simultaneously And one end is mounted in oblong slots, lower die holder 10 be equipped with lower graduation mark 17,0 point for left module 11, right mould block 12 outside Face, spring 13 are fixed on the inside of left module 11,12 one end of right mould block；Wedge mechanism 5 includes wedge block 14 and adjusting screw rod 15, Wedge block 14 is mounted in guide groove 16, and adjusting screw rod 15 pushes wedge block 14 to move to left module 11, right mould along guide groove 16 Between block 12, left module 11, right mould block 12 is pushed to move in oblong slots.

It is formed using the molding die, comprising the following steps:

1 is moved to 9 one end of lock belling mould needed for the molding of part taper in holding tank 8 from the 0 of high scale line 6 point At the graduation mark of designated position；Wedge block 14 pushes left module 11 to form cone tank with right mould block 12, reaches size at its big end Size needed for forming part taper；

Part plate is placed on left and right module 11,12 upper surfaces by corresponding code requirement by 2, and lathe top shoe drives Upper die component 3 moves downward, and plate is pressed into the cone tank that left and right module 11,12 surrounds by lock belling mould 9 completes a molding Movement, lathe top shoe drive 3 uplink of upper die component, the plate stroke as defined in the Taper Pipe radial feed again, lathe top shoe It drives lock belling mould 9 to be pressed into plate in the cone tank that left and right module 11,12 surrounds again, it is dynamic to complete second of molding Make ... .. with the continuous feed of plate, constantly repeats lock and press work, plate feed motion presses to be formed with 9 lock of lock belling mould Compound motion, so that Taper Pipe part is realized eccentric molding in forming process；

After the completion of 3 moldings, adjusting mold makes lock belling mould 9 be reset to original state；Adjusting screw rod 15 pulls wedge block 14 It retreats, left module 11, right mould block 12 are reset to original state under the action of spring 13.
