Description
Technical field
The utility model relates to a kind of softening extension fixture, and especially a kind of heat-shrinkable T bush softens extension fixture.
Background technology
Heat-shrinkable T bush is to be made by material contracting with heat, and it can shrink after heating automatically, thereby extensively applies to pipeline, field such as packing.
Heat-shrinkable T bush needs to soften the expansion typing before finished product, i.e. heating is softened heat-shrinkable T bush and utilized external force to pull heat-shrinkable T bush and makes its expansion typing.Expansion typing at present commonly used has two kinds of methods: 1, vacuum expansion method, and with the mould of heat-shrinkable T bush heating, utilize the heat-shrinkable T bush pressure inside to make the heat-shrinkable T bush expanding and shaping through vacuumizing.2, mechanical expansion method with the heat-shrinkable T bush heating, makes its expanding and shaping thereby utilize expansion machinery to tear heat-shrinkable T bush then.Vacuum expansion method is utilized the atmospheric pressure effect, and the power of its generation is limited, is difficult to the expanded dimension that reaches predetermined and mould and employed vacuum equipment complex and expensive for larger-size heat-shrinkable T bush.Traditional mechanical expansion method utilizes two turning cylinders to pull, for example the applying date is the Chinese patent of CN201645820 for the 2010.5.17 publication number, it utilizes the turning cylinder of two spinnings to pull heat-shrinkable T bush, and heater heat hot Heat-Shrinkable Tubings is set below rotating shaft, because heat-shrinkable T bush is less in corner's angle of rotating shaft, therefore forming stress easily concentrates, cause the damage of heat-shrinkable T bush, and its heater only can be heated to the bottom of heat-shrinkable T bush, its top still is in the state of cooling, therefore the temperature difference of top and bottom is bigger, thereby makes that under the pullling of identical power top is different with the expanded dimension of bottom.
The utility model content
Technical problem to be solved in the utility model provides a kind of heating and the softening extension fixture of the uniform heat-shrinkable T bush of active force.
The heat-shrinkable T bush that its technical problem that solves the utility model adopts softens extension fixture, comprise support, travel driving unit, be arranged on turning cylinder and heater on the support, described support is provided with guide runner, turning cylinder is provided with walking mechanism and matches with guide runner, described walking mechanism links to each other with travel driving unit, described turning cylinder is provided with three at least, and described heater is arranged on rotating collar in the stent area that forms.
Further be, turning cylinder is provided with three, and described three turning cylinders are that the center of circle circumferentially evenly is provided with the heater.
Further be, also comprise rotary electric machine, described rotary electric machine links to each other with turning cylinder.
Further be that heater is triangular in shape and its three summits are corresponding respectively with three turning cylinders.
The beneficial effects of the utility model are: by a plurality of turning cylinders are set, thereby heat-shrinkable T bush is supported for polygon, so just can disperse the power of pullling each position to heat-shrinkable T bush, and the angle that the heat-shrinkable T bush that makes the turning cylinder place forms increases, concentrate thereby reduce stress, prevent the damage of heat-shrinkable T bush.Heater is arranged in the zone that heat-shrinkable T bush surrounds, so just can uniform heating to each position of heat-shrinkable T bush, thereby make the softening more even of heat-shrinkable T bush.Thereby turning cylinder can be provided with three complexity that reduce devices, and at the center of three turning cylinders heater is set and makes that heating is more even.Heater can also be set to and three triangles that turning cylinder is similar, thereby makes each face of heat-shrinkable T bush be heated evenly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a front view of the present utility model;
Parts, position and numbering among the figure: support 1, turning cylinder 2, heater 3, guide runner 4, running gear 5, heat-shrinkable T bush 6.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises support 1, travel driving unit, is arranged on turning cylinder 2 and heater 3 on the support 1, described support 1 is provided with guide runner 4, turning cylinder 2 is provided with walking mechanism 5 and matches with guide runner 4, described walking mechanism 5 links to each other with travel driving unit, described turning cylinder 2 is provided with three at least, and described heater 3 is arranged on turning cylinder 2 around in support 1 zone that forms.In use, heat-shrinkable T bush 6 is enclosed within turning cylinder 2, heat-shrinkable T bush 6 has just formed polygon thus.Turning cylinder 2 is in initial position, because the heat-shrinkable T bush 6 of all size is not of uniform size, therefore, the initial position of each turning cylinder 2 can be set according to concrete specification, preferably turning cylinder 2 is arranged in regular polygon, and also can keep regular polygon when keeping turning cylinder 2 with respect to the motion of support 1, promptly its movement velocity is the same, and the direction of motion is consistent with the angle of regular polygon formation.After placing heat-shrinkable T bush 6, both can start heater 3, be positioned at the heat-shrinkable T bush 6 that the middle heater 3 of polygon scatters to heat each position uniformly, thereby make heat-shrinkable T bush 6 thermally equivalents, restart travel driving unit this moment, can be motor, hydraulic means, starting drive etc., make turning cylinder 2 outwards move, thereby enlarge polygon, make heat-shrinkable T bush 6 expand, heater 3 can improve power in good time, thereby finally finishes the expanding and shaping of heat-shrinkable T bush 6.Owing to adopted a plurality of turning cylinders 2, therefore heat-shrinkable T bush 6 is bigger in corner's angle of turning cylinder 2, pull at turning cylinder 2 and to be not easy to form stress in the motion and to concentrate, and heater 3 can be each position heating of heat-shrinkable T bush 6 uniformly, avoided the temperature contrast on the heat-shrinkable T bush 6, therefore, adopt the quality that can improve product behind this device.
In order to simplify structure of the present utility model, as Fig. 1 or shown in Figure 2, turning cylinder 2 is provided with three, and described three turning cylinders 2 are that the center of circle circumferentially evenly is provided with heater 3.After adopting said structure, turning cylinder 2 reality have formed equilateral triangle, have so just reduced the quantity of turning cylinder 2, make device more succinct, and heater 3 is positioned at the center of equilateral triangle, so its heating will be more even.
In order to make heat-shrinkable T bush 6 stressed being heated evenly in heating and pullling, also comprise rotary electric machine, described rotary electric machine links to each other with turning cylinder 2.Utilize the rotation of turning cylinder 2, thereby make heat-shrinkable T bush 6 rotate, therefore be rotated the effect that axle 2 positions that stop also can be subjected to heater 3, the part that contacts with turning cylinder 2 can not contact with turning cylinder 2 in rotation yet, like this, heat-shrinkable T bush 6 is heated with stressed just more even.
In order to make heating more even, as depicted in figs. 1 and 2, heater 3 is triangular in shape and its three summits are corresponding respectively with three turning cylinders 2.Heater 3 can be formed equilateral triangle by three heating surfaces, and the corresponding heat-shrinkable T bush 6 of each heating surface forms the face of equilateral triangle, and heating surface can be made by resistance wire, infrared heater.So just can better guarantee the uniformity that heats, improve the quality of product.
