Abstract
The utility model discloses an AT rail hot-forging forming inserting-pin-type quick die changing device which is composed of mutually-embedded connecting pairs and an inserting pin positioning and locking mechanism. The mutually-embedded connecting pairs include a mutually-embedded connecting pair A and a mutually-embedded connecting pair B which are mutually embedded, and the inserting pin positioning and locking mechanism comprises pin holes arranged at corresponding positions of the mutually-embedded connecting pair A and the mutually-embedded connecting pair B, and positioning pins matched with the pin holes. By adopting the technical scheme, forging production efficiency and processing technique level of existing turnout root ends are improved, turnout product yield is increased, die changing operation can be simplified, the objectives of quick die changing, improving of die changing efficiency and reducing of labor intensity of manpower are achieved, and connecting strength of dies is improved.
Description
Technical field
The utility model relates to the frock technical field of AT rail hot-forging forming, is specifically related to a kind of mould changing device.
Background technology
In the production of railway switch, dwarf forms special section frog end (being commonly called as AT rail) need to be configured as to standard section rail by forge hot mode, for circuit on standard section steel rail connect.
Current rail heel end forging field, the replacing pattern of mould is various, ubiquity die change speed is slow, die change action is complicated, the replacing of especially compound extruding loose piece class mould, owing to adopting single bolt arrangement, mould volume is larger, connects rigidity, intensity difference, and die shank connects employing bolted, cause in actual production, cause in forging product conversion production process, mould replacing time is long, personnel's inconvenient operation, the disengaging of mould and attended operation difficulty etc., have a strong impact on the normal production operation that heel end forges.
Summary of the invention
In order to solve, the mould replacing time existing in prior art is long, personnel's inconvenient operation, the problem of the disengaging of mould and attended operation difficulty, and the utility model provides a kind of new technical scheme:
AT rail hot-forging forming bolt-type quick die change device, described quick die change device is comprised of inter-embedding type auxiliary connection and latch location locking mechanism; Described inter-embedding type auxiliary connection comprises chimeric inter-embedding type auxiliary connection A and inter-embedding type auxiliary connection B mutually; Described latch location locking mechanism comprises the pin-and-hole of the correspondence position of being located at inter-embedding type auxiliary connection A and inter-embedding type auxiliary connection B, and the alignment pin coordinating with above-mentioned pin-and-hole.
Inter-embedding type auxiliary connection A is connected by two bolts with mould, and in the technical program, one of them inter-embedding type auxiliary connection A connects manomelia finisher, and another inter-embedding type auxiliary connection A connects long limb finisher, and the auxiliary connection physical dimension of above-mentioned mould is identical.
Described inter-embedding type auxiliary connection B connection mode sleeve, is provided with die shank back-moving spring between described die shank cover and inter-embedding type auxiliary connection B.
Pair in mutual embedded connection is designed to locating hole syndeton, after aligning, inserts special alignment pin by auxiliary connection locating hole, realizes the quick-replaceable location of mould; During die change, alignment pin is extracted, completed the dockingundocking of mould and die shank, hang away the mould of not working subsequently, pack into die needed; After both mold ends auxiliary connection locating hole aligns, insert alignment pin, complete being located by connecting of new die.Whole quick-replaceable process, without the operation that is threaded, is changed action fast succinct;
The beneficial effects of the utility model:
By adopting the technical solution of the utility model to promote existing track switch heel end forging production efficiency and technology level, reach lifting track switch product yield, can simplify die change operation, realize quick die change, improve die change efficiency, alleviate the object of hand labor intensity and improve the bonding strength of mould.
Further technique effect is, the technical solution of the utility model is rational in infrastructure, simple and practical, highly versatile, the feature such as convenient for installation and maintenance, be not only applicable to heel end and forge loose piece class mould die change and use, and design principle and implementation change and have important directive significance other forms of heel end forging mold, can be widely used in the application enhancements of rail part heel end process for forging.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of AT rail hot-forging forming bolt-type quick die change device of the present utility model.
1-mould connects assembly; 2-manomelia finisher; The long limb finisher of 3-; 4-shaping base plate; 5-alignment pin; 6-inter-embedding type auxiliary connection A; 7-rail head mould; 8-inter-embedding type auxiliary connection B; 9-die shank back-moving spring; 10-die shank cover.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described further.
As shown in Figure 1, AT rail hot-forging forming bolt-type quick die change device, it comprises rail head mould 7, and rail head mould 7 is provided with shaping template above, and wherein the left side of rail head mould 7 is provided with manomelia finisher 2; Right side is provided with long limb finisher 3, and AT rail is at above-mentioned mould intermediate heat forging molding.
Described manomelia finisher 2, long limb finisher 3 are connected with inter-embedding type auxiliary connection A6 by two bolt arrangements, die shank cover is connected with inter-embedding type auxiliary connection B8, inter-embedding type auxiliary connection A6 and inter-embedding type auxiliary connection B8 are chimeric mutually, and wherein inter-embedding type auxiliary connection A6 is embedded in inter-embedding type auxiliary connection B8.The position that inter-embedding type auxiliary connection A6 is corresponding with inter-embedding type auxiliary connection B8 is provided with pin-and-hole, and described alignment pin 5 is inserted in above-mentioned pin-and-hole.
As shown in Figure 1, alignment pin 5 locking inter-embedding type auxiliary connection A6 and manomelia finishers 2, mould forms mould with die shank cover and is connected assembly 1; Inter-embedding type auxiliary connection A6 is separated with long limb finisher 3, and mould is separated with die shank cover, is convenient to more mold exchange.
My company is is researching and developing in the development project of 5000 tons of < < rail heel end hot forging forming automatic control system > > that carry out, and automatic mold-change part will adopt technical solutions of the utility model design content by the connection of mould.
