Description
Technical field
The present invention relates to electric capacity groove forming mould and the shaping and demoulding method of electric capacity pillow.
Background technology
On railway track, every 100m left and right, an electric capacity pillow can be set; electric capacity was exposed on railway ballast in the past, caused capacitance damage, stolen, affected the problem of the normal maintenance work of circuit; the electric capacity pillow of the railway department design be in recent years all self with form of grooves, electric capacity has been formed to good protection.Although electric capacity pillow consumption is less, on circuit, must arrange again, different track layings is the sleeper of different model simultaneously, sleeper model has reached kind more than ten at present, if the electric capacity pillow mould of buying Multiple Type can cause very large expense.
Summary of the invention
In order solving, in prior art, to prepare the electric capacity of different model and to rest the head on the technical matters that need to use the electric capacity pillow mould of different model and cause productive costs to improve, the invention provides a kind of electric capacity groove forming mould that is applicable to any electric capacity pillow mould.
The electric capacity groove forming mould of electric capacity pillow of the present invention, is located on electric capacity pillow punching block housing, comprising: fixing steel plate, electric capacity groove forming panel and builtin-nut, and described electric capacity groove forming panel is fixed on fixing steel plate by the first registration device; Described builtin-nut is fixed on fixing steel plate by the second registration device; Electric capacity groove forming panel and builtin-nut are positioned at the homonymy of fixing steel plate.
Builtin-nut is the permanent fixture of staying in sleeper, packs in punching block before production, after the sleeper demoulding, also no longer takes out, and while being convenient to add a cover over cap on the electric capacity groove of electric capacity pillow, over cap is fixed.
Preferably, described the first registration device comprises the first knock hole, locating bush and dowel bolt, and the quantity of the first knock hole, locating bush and dowel bolt matches; Wherein said the first knock hole is opened on fixing steel plate; Locating bush is arranged in the first knock hole; Described electric capacity groove forming panel is provided with internal thread hole corresponding to the position of the first knock hole below, and described dowel bolt is fixed in described internal thread hole through locating bush.
Because the punching block housing of a set of production sleeper has the die space of 8 ~ 10 sleepers, so electric capacity groove forming panel just should have 8 ~ 10 mutually, each groove forming mould can produce certain error adding man-hour, the spacing of the first knock hole on fixing steel plate adds and also has certain error man-hour, so need to increase locating bush, reserves some free gaps and adjusts these errors.
Preferably, in described the first knock hole, be provided with negative thread, described locating bush one end is provided with for being fixed in the outside thread on fixing steel plate, the thickness matching of externally threaded length and fixing steel plate, the outer rim shape of the other end is mated with spanner holding part, and the first knock hole is threaded fixing with locating bush.Locating bush is designed to such shape, on the one hand in order to be combined with fixing steel plate more firmly, on the other hand, also makes locating bush be convenient to dismantle with spanner.The first knock hole is provided with negative thread, conveniently when not producing electric capacity pillow, directly with bolt, blocks, and can produce regular sleeper like this.
Preferably, described locating bush prolongs central axis direction and is provided with through hole, and the diameter of through hole is greater than the diameter of dowel bolt.The through hole that is split into light circle in locating bush, gives exactly the certain free gap of dowel bolt and guarantees that each groove forming panel can exchange.
Preferably, the number of described the first registration device is at least 2.
Preferably, the number of described the second registration device and default nut matches, and the second registration device comprises the second knock hole and dowel bolt, and dowel bolt and the second knock hole quantity match; The second knock hole is opened on fixing steel plate, and builtin-nut is provided with internal thread hole corresponding to the position of the second knock hole below, and dowel bolt is positioned internal thread hole place through the second knock hole.
Preferably, described the second knock hole is provided with the negative thread mating with dowel bolt, and the second knock hole is threaded fixing with dowel bolt.
Preferably, the number of described builtin-nut and the second registration device is all at least 2.
Preferably, described electric capacity groove forming panel is the half round post along center shaft rip cutting, its tangent plane and fixing steel plate laminating; Described fixing steel plate is welded on punching block housing.Fixing steel plate is forever stayed in punching block after being welded on punching block housing, while producing electric capacity pillow, packs electric capacity groove forming mould and builtin-nut into, while producing regular sleeper, directly with bolt, the first knock hole and the second knock hole is blocked.
The present invention also provides a kind of shaping and demoulding method of electric capacity groove forming mould of above-mentioned electric capacity pillow, is that electric capacity groove forming panel and builtin-nut are assembled on fixing steel plate, becomes one with punching block housing, and sleeper is produced in concreting; After maintenance finishes, first unload whole dowel bolts, make sleeper demoulding together with electric capacity groove forming panel, and then use and draw yard instrument from sleeper, to take out electric capacity groove forming panel;
The described yard instrument that draws, comprise bracing frame, header board and draw a yard bolt, support frame as described above is surrounded by 4 stay bearing plates, header board is fixed on bracing frame top and is provided with for the perforation of drawing yard bolt to pass, wherein, the base length of every stay bearing plate is all greater than the corresponding length of side of electric capacity groove forming panel and fixing steel plate contact surface; The internal thread hole number of perforation number and electric capacity groove forming panel matches.
Above-mentioned structure of drawing yard instrument, the quiet empty planar dimension that 4 stay bearing plates are surrounded is slightly larger than each direction of electric capacity groove forming panel tangent plane planar dimension, be mainly that while considering to pull out electric capacity groove forming panel with bolt, the bad words of contraposition may be pushed up on stay bearing plate, causing can not the demoulding; But too large words have some damages to surrounding concrete, may be with brokenly a part of surrounding concrete, so the annular that back-up block forms is mainly that groove cement concrete is around formed to certain protection.
Beneficial effect of the present invention: electric capacity pillow electric capacity groove forming mould of the present invention easy disassembly, the electric capacity that can adapt to various models is rested the head on, and has reduced die cost, also have simple in structure, easy operating, the features such as strong adaptability, the electric capacity pillow that can be widely used in various models is produced.
