Turnout Snow Melting Fixture Standing Processing Device

Abstract

The invention provides a setting treatment device for a turnout snow-melting fixture. The setting treatment device comprises a support; a support panel is provided with a guide groove; one side of the guide groove is provided with a first positioning pin; the other side of the guide groove is provided with a second positioning pin; a plurality of limiting holes are disposed between the first positioning pin and the second positioning pin; the limiting holes are detachably provided with limiting pins; the guide groove penetrates through two side surfaces of the support panel; the first positioning pin, the second positioning pin and the limiting holes are all disposed at one side of the support panel; the other side of the support panel is provided with a force-applying mechanism; the force-applying mechanism is provided with a roller shaft at the end close to the guide groove; and the roller shaft is vertical to the support panel and penetrates through the guide groove. The setting treatment device is simple in operation and low in cost and can realize setting treatment for a plurality of turnout snow-melting fixtures. Besides, the setting treatment is convenient for mechanism installation and adjustment, is suitable for large-scale production and can realize the setting treatment of the turnout snow-melting fixture and guarantee the quality of the fixture.

Description

technical field

[0001] The invention belongs to the technical field of metal processing, and in particular relates to a standing processing device for a turnout snow-melting jig. Background technique

[0002] Snow-melting jigs are new products to ensure the safe conversion of railway speed-up turnouts in winter. There are many types of snow-melting jigs, such as image 3 , Figure 4 As shown, this type of fixture is a spring product, and the use conditions are harsh. It requires that the clamping force be within a certain force range after installation, and at the same time, the fixture must not be damaged due to excessive opening when it is installed, and it must have a large deformation capacity. From this, it can be concluded that the fixture needs standing treatment; the standing treatment is that the spring is compressed (stretched, twisted) to the height (length, torsional deformation angle) under the test load and unloaded quickly, and the cycle is repeated successive...
