Abstract
A combined type stretch-draw cover for high ferro prestressed track board mold, comprises rubber stretch-draw cover, and the outside of described rubber stretch-draw cover is configured with outer steel sleeve, and the described external diameter of rubber stretch-draw cover and the internal diameter of described outer steel sleeve are arranged to male-female engagement face.The combined type stretch-draw cover of this high ferro prestressed track board mold overlaps combination by outer steel sleeve and rubber stretch-draw and forms, overlap on pilot hole by the welded and installed of outer steel sleeve and side template in the stretch-draw of side template during assembling, utilize rubber stretch-draw cover and outer steel sleeve coordinate and rubber stretch-draw cover realized sealing with coordinating of prestressing force pull-rod, while simplified processing process, substantially increase the unfailing performance that stretch-draw cover uses.
Description
Technical field
The utility model relates to high-speed railway concrete track board forming die, is specifically related to a kind of combined type stretch-draw cover of high ferro prestressed track board mold.
Background technology
Stretch-draw cover is the assembly of high ferro pre-stress rail board forming die, and it is arranged in the template of side, for the sealing of deformed bar stretch-draw rod.The rubber sleeve of the rubber stretch-draw cover outstanding seal face for two ends are provided with generally used at present, the two ends seal face of its body and the two sides fitted seal of side template, the simultaneously endoporus of body and stretch-draw rod interference fit, realize rubber stretch-draw be placed in the template of side fix and with being sealed and matched of side template and stretch-draw rod.Because prestressed stretch-draw number of steel bars is many, the skew of its position is comparatively large, and the distortion of mould load change is added in the axial displacement of simultaneous tension reinforced bar stretching elongation, the injury that factors overlaps rubber stretch-draw can be formed, cause rubber stretch-draw to overlap the accidents such as distortion, damage, spillage.In addition, the both sides mating surface of this kind of rubber stretch-draw cover opposite end side template has certain requirement, and for ensureing sealing, usually need the both sides mating surface of opposite end side template to carry out machined, its processing technology is complicated, adds the manufacturing cost of mould.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of combined type stretch-draw cover of high ferro prestressed track board mold, to improve the unfailing performance of stretch-draw cover, and simplifies the processing technology of side template, reduces the manufacturing cost of mould.
The technical scheme realizing above-mentioned purpose is: a kind of combined type stretch-draw cover of high ferro prestressed track board mold, comprise rubber stretch-draw cover, the outside of described rubber stretch-draw cover is provided with outer steel sleeve, and the described external diameter of rubber stretch-draw cover and the internal diameter of described outer steel sleeve are arranged to male-female engagement face.
Further, the endoporus of described rubber stretch-draw cover is anterior with prestressing force pull-rod interference fit.
Further, the anterior external diameter interference fit of overlapping with described rubber stretch-draw of the endoporus of described outer steel sleeve.
The combined type stretch-draw cover of this high ferro prestressed track board mold overlaps combination by outer steel sleeve and rubber stretch-draw and forms, overlap on pilot hole by the welded and installed of outer steel sleeve and side template in the stretch-draw of side template during assembling, utilize rubber stretch-draw cover and outer steel sleeve coordinate and rubber stretch-draw cover realized sealing with coordinating of prestressing force pull-rod, while simplified processing process, substantially increase the unfailing performance that stretch-draw cover uses.
Accompanying drawing explanation
Fig. 1 is the combined type stretch-draw nested structure schematic diagram of this high ferro prestressed track board mold.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described.
As Fig. 1, the combined type stretch-draw cover of this high ferro prestressed track board mold, overlaps 1 by rubber stretch-draw and forms with the outer steel sleeve 2 be assemblied in outside this rubber stretch-draw cover 1.Steep-taper cone is arranged in the front end of described rubber stretch-draw cover 1, and protrude from the front end face of outer steel sleeve 2, the front end face of outer steel sleeve 2 and the medial surface of side template 3 are at same plane, the rear end face of outer steel sleeve 2 protrudes from the lateral surface of side template 3, and the rear end face of rubber stretch-draw cover 1 and the rear end face of outer steel sleeve 2 are at same plane.The outer diameter face of rubber stretch-draw cover 1 arranges a rectangle annular groove, and the aperture surface of outer steel sleeve 2 is arranged the rectangle land that rectangle annular groove overlap 1 with rubber stretch-draw coincide, the male-female engagement face structure of 1 external diameter and outer steel sleeve 2 internal diameter is overlapped in formation rubber stretch-draw.
1 external diameter and outer steel sleeve 2 internal diameter interference fit are overlapped in the rubber stretch-draw of the combined type stretch-draw cover of this high ferro prestressed track board mold, and 1 internal diameter is overlapped in rubber stretch-draw and prestressing force pull-rod interference fit realizes sealing.
As Fig. 1 embodiment, endoporus front portion and the prestressing force pull-rod interference fit of rubber stretch-draw cover 1, the endoporus rear portion of rubber stretch-draw cover 1 coordinates with prestressed stretch-draw nod gap, while its sealing property of guarantee, improves the assembly performance of rubber stretch-draw cover 1 and prestressing force pull-rod.
As Fig. 1 embodiment, the major diameter fit of 1 is overlapped in endoporus front portion and the rubber stretch-draw of outer steel sleeve 2, and the crest clearance that endoporus rear portion and the rubber stretch-draw of outer steel sleeve 2 overlap 1 coordinates, and improves the assembly performance of rubber stretch-draw cover 1 and outer steel sleeve 2 while ensureing its sealing property.
As Fig. 1 embodiment, the rear portion diameter of rubber stretch-draw cover 1 is relatively large, to increase the resistance of rubber stretch-draw cover 1 to vibration inside side template 3.
