Technical field
The utility model relates to a kind of stretching-machine, especially relates to a kind of structural improvement of processing the automatic stretching-machine of the seamless liquid line special use of macromolecule.
Background technology
The applicant had once applied for the patent (patent No. is 99252858.5) of " bench of PAP " by name in 1999, this patent application discloses a kind of like this pipe drawing machine: be provided with device for drawing die and by motor-driven pipe drawing dolly at an end of frame, wherein, device for drawing die system is by the drawing-die stereotype plate that is fixed on the frame, die holder provided thereon and the die case and the drawing-die composition thereof of phase configuration with it.Though this patent provides a kind of tool of production for producing PAP, but still exist the multiple tube bench and when trombone slide, can not accomplish to automatically reset, and the difficult deficiency that can arbitrarily adjust bore etc.
Summary of the invention
The utility model mainly is that the bench that solves the existing in prior technology multiple tube can not be accomplished to automatically reset when trombone slide, and also difficulty can solve the problem of arbitrarily adjusting bore according to actual needs, makes production efficiency comparatively low; Now provide a kind of production cost low, production efficiency is higher, and can satisfy the stretching-machine of the multiple tube of automatic trombone slide demand.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: comprise pipe drawing dolly that places on the frame and the device for drawing die of being located at frame one end, described device for drawing die is fixed on the frame by shaping rack, described shaping rack is made of mould positioning disk and the guiding ennation of being located at its outside, both are arranged on the same axis, and be provided with retainer plate within it, in described retainer plate, be provided with fairlead, and be provided with reducing mold at the front end of described fairlead.
As preferably, described guiding ennation and described shaping rack are made into integration, and the length of described guiding ennation be 5-15 by the ratio in trombone slide footpath: 1.The comparatively elongated guiding ennation that is coaxially set can improve pipe running orbit steady, straight of trombone slide greatly, thereby the multinomial quality index of body is greatly improved.
As preferably, described reducing mold system is made up of step-like overcoat and the reducing drawing-die be located in it, and the inwall of described reducing drawing-die is taper shape, and its opening tapering is 25 °-35 °.The stretching undergauge of appropriateness can make the glue on inner wall of metal tube and the macromolecular material closely cooperate.
As preferably, is provided with the sprocket wheel that drives through reducing gear by motor by the described drawing-die shaping rack, an end of secondary chain provided thereon links to each other with pipe drawing dolly.
As preferably, described frame is provided with position sensor, and described pipe drawing dolly wheel triggers its action, and does corresponding motion by its control motor.
Because reducing mold overcoat and the firm reducing die case of hard alloy place in the described shaping rack, thereby can change corresponding mould specification at any time according to product requirement, it is comparatively convenient to change.
Therefore, the utlity model has simple and reasonable for structurely, easy to operate, the total quality of the multiple tube of processing is higher, the external diameter homogeneous, and squeezing effect is good, and can be according to needs of production, regulates characteristics such as the different length of processed multiple tube and bore easily.Be particularly useful for the stretching of elongated shape PAP, the forward part operation of extruding composite molding.
Description of drawings
Accompanying drawing 1 is a kind of frame dolly of the present utility model and running part structural representation;
Accompanying drawing 2 is structural representations of a kind of drawing-die shaping rack of the present utility model;
Accompanying drawing 3 is structural representations of a kind of reducing mold of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1, pipe drawing dolly 14 and the device for drawing die 11 of being located at frame 12 1 ends are arranged on the frame 12 on the automatic stretching-machine 1, be provided with position sensor simultaneously.Device for drawing die is fixed on the frame 12 by shaping rack 20, the drawing-die shaping rack 20 other sprocket wheels 19 that drive through reducing gear by motor 25 that are provided with, and an end of secondary chain provided thereon links to each other with pipe drawing dolly 14, and described sprocket wheel 19 is fixed on the bearing block 17.Drawing-die shaping rack 20 is made of mould positioning disk 20A and the guiding ennation 20B that is located at its outside, guiding ennation 20B and described shaping rack 20 are made into integration, both are arranged on the same axis, and the guiding ennation length be 5-15 by the ratio in trombone slide footpath: 1.Mould positioning disk 20A and the guiding ennation 20B that is located at its outside can be by sandbox casting and be processed into one, or be connected with bolt in the junction of the guiding ennation 20B in the mould positioning disk 20A and the outside.And in drawing-die shaping rack 20, be provided with retainer plate 21, and being provided with fairlead 22 in this retainer plate 21, the front end of fairlead 22 is provided with reducing mold 23 (as shown in Figure 2).Reducing mold 23 is made up of step-like overcoat 26 and the reducing drawing-die of being located in it 27, and it is conical that the inwall of reducing drawing-die 27 is, and its opening tapering is 30 ° (referring to Fig. 3).
During use, start, drive decelerator 16 drive sprockets 13 drive main chain bars and rotate to clockwise direction through buncher 15, the dolly chain hook is joined in the main chain bar, and the dolly jaw will vise metal tube automatically, simultaneously to moving clockwise, to the regular length point, trundle is run into limit switch, automatic stopping, start buncher 25 simultaneously, drive worm reduction gear 24, drive auxilliary chain, make dolly sprocket wheel 18 to motion counterclockwise, when dolly wheel is run into limit switch, repeat said process.The function of drawing-die shaping rack is that the metal tube that will get off from last process is inserted in the straightening fairlead 22, and enter the reducing die orifice, and vise metal tube by the dolly jaw, carry out cold drawn, reach metal tube straightening, undergauge, the glue-line on inner wall of metal tube and the macromolecular material is closely cooperated.Reducing mold 23 is made up of overcoat 26 and the firm reducing drawing-die 27 of hard alloy, constitutes one together with fairlead 22, the retainer plate 21 be located in it, and it can change mould specification at any time according to product requirement, only needs to become corresponding specification to get final product above-mentioned each part replacement.
