Adopt the utility model discloses, can eight point location accurate control switch tie lengths on four sides, switch tie tip is difficult for crooked, makes ordinary and high-speed switch tie length aspect qualification rate 100%, and does not hinder the work panel when changing the mould, and easy operation is favorable to improving the steel mould life-span, does not need rubber partition and wedge stuff, and the cost of manufacture is low.
Description
Technical Field
The utility model relates to an elastic length positioner of joint formula switch tie steel mould.
Background
In the currently used communicated switch tie steel mould, a mode that two iron baffles clamp a rubber partition plate device is generally adopted between a sleeper and a sleeper, and the rubber partition plate is fixed by strip-shaped round steel welded on a side plate of the steel mould; and when the wood is molded, the rubber partition plate device is taken out, and two wedge-shaped wood strips are added. The end part of the switch tie produced by the mode is easy to be inclined, the length control of the switch tie is inaccurate, especially the length of the high-speed switch tie is difficult to meet the requirement of +/-5 mm, the length qualified rate is generally below 50 percent, and the position of the strip-shaped round steel is required to be moved and positioned during die change, so that a panel is easy to damage.
Disclosure of Invention
The utility model aims at the aforesaid not enough, provide can accurate control switch tie length, the switch tie tip is difficult for crooked, and does not hinder the work panel when changing the mould, and easy operation is favorable to improving the elastic length positioner of a communicated type switch tie steel mould in steel mould life-span.
The utility model adopts the technical proposal that: the utility model provides an elastic length positioner of communicated switch sleeper steel mould, includes closed framework, is equipped with sliding sleeve and spring in closed framework, and the sliding sleeve is the convex structure, and the rear end of sliding sleeve is equipped with the recess, and the recess at the sliding sleeve is established to the one end of spring, and the front end of sliding sleeve is the protruding portion, and outside the protecgulum of closed framework was stretched out to the protruding portion, the rear end card of sliding sleeve was in closed framework, and the other end of spring links up with the inside wall of the protecgulum of closed framework mutually.
Adopt the utility model discloses, can eight point location accurate control switch tie lengths on four sides, switch tie tip is difficult for crooked, makes ordinary and high-speed switch tie length aspect qualification rate 100%, and does not hinder the work panel when changing the mould, and easy operation is favorable to improving the steel mould life-span, does not need rubber partition and wedge stuff, and the cost of manufacture is low.
Drawings
Fig. 1 is a schematic view of the present invention.
Fig. 2 is a schematic view of the installation on the steel mold of the communicating switch tie.
The numbers in the figure indicate: the switch sleeper steel die comprises a closed frame body 1, a sliding sleeve 2, a groove 3, a front cover 4, a spring 5, a rear cover 6, a bolt 7 and switch sleeper steel die channel steel 8.
Detailed Description
The present invention will be further described with reference to the following specific examples.
Referring to fig. 1 and 2, the elastic length positioning device of the communicated switch tie steel die comprises a closed frame 1, a sliding sleeve 2 and a spring 5 are arranged in the closed frame 1, the sliding sleeve 2 is of a convex structure, a groove 3 is formed in the rear end of the sliding sleeve 2, one end of the spring 5 is arranged in the groove 3 of the sliding sleeve 2, the front end of the sliding sleeve 2 is a protruding part, the protruding part extends out of a front cover 4 of the closed frame 1, the rear end of the sliding sleeve 2 is clamped in the closed frame 1, and the other end of the spring 5 is connected with the inner side wall of a rear cover 6 of the closed frame 1.
When the device is used, the pair of elastic length positioning devices are correspondingly arranged at the position of an iron baffle plate (not marked in the figure) at one end of the switch sleeper steel die channel steel 8 through the bolt 7, the other pair of elastic length positioning devices are correspondingly arranged at the position of an iron baffle plate (not marked in the figure) at the other end of the switch sleeper steel die channel steel 8 through the bolt 7, so that the protruding parts of the sliding sleeves 2 of the two pairs of elastic length positioning devices are opposite, and then the iron baffle plates (not marked in the figure) at the two sides are fixed at the two sides of the elastic length positioning devices through U-shaped clamps; then, add concrete vibration molding in switch sleeper steel mould channel-section steel 8, at this moment, the sliding sleeve 2 of elastic length positioner keeps unchangeable, and the protruding portion of sliding sleeve 2 compresses to the protecgulum 4 plane position that does not exceed closed framework 1 when putting open, and the sleeper rebound primary position again after the drawing of patterns, take out the U type card again after vibration molding can. Because the accurate positioning of eight points through four sliding sleeves 2 in the elastic length positioner, can accurate control switch tie length, switch tie tip also is difficult crooked, simultaneously, if need change the mould, only need move elastic length positioner fixed position can, can not harm switch tie steel mould channel-section steel 8's panel.
