Problems solved by technology

[0005] The above-mentioned guide rails are generally made of aluminum alloy, steel and other metals. There is rolling friction between the rollers and the bottom plate during the process of pushing and pushing the handcart. In the long run, there will be quality problems such as burrs and scratches on the surface of the bottom plate, which will cause its surface roughness and resistance. Increased, the handcart is laborious to move between the stations, which needs to be improved

Embodiment 1

[0058] A switch cabinet slide rail, such as figure 1 As shown, it is installed in the two opposing chambers of the vacuum circuit breaker of the switch cabinet, and cooperates with the rollers on both sides of the handcart vacuum circuit breaker to play the role of guiding and limiting. Its structure includes a side plate 1 connected to the inner side of the cabinet, and the side plate 1 is fixedly connected with a limit strip 2, a track plate 3, and a fixed plate 4 from top to bottom. The surface of the side plate 1 is provided with a plurality of mounting holes 11 , relief notches 12 and clamping holes 13 . The installation hole 11 is used for screwing in, so that the side plate 1 is fixedly connected with the cabinet body; the relief gap 12 is used to give way to other electrical components in the switch cabinet; the clamping hole 13 is located at the opening of the side plate 1 towards the cabinet body One end is used to fix the vacuum circuit breaker.

Embodiment 2

[0061] The production process of slide rail in embodiment one is as follows:

[0062] S1 Preheating: Heat the ingot cylinder to 380°C at a heating rate of 85°C / H, then put the aluminum rod in, and heat it to 460°C at a heating rate of 90°C / H, keep it for 2H, select according to the section of the slide rail Extrusion die designed and manufactured, heated to 440, heat preservation 3H;

[0063] S2 Extrusion: install the heated aluminum rod and mold on the extruder, the extruder works, the aluminum rod is extruded, the extrusion speed is ≤180kg / cm2, and the temperature is 400°C;

[0064] S3 Quenching: The exit of the extruder is quenched by spraying water mist to reduce the temperature of the profile to below 50°C;

[0065] S4 Stretch Straightening: Use a straightening machine to pull the end to straighten the profile;

[0066] S5 cutting: cutting the profile so that its length is 70cm;

[0067] S6 cold punching: use cold punching process to punch out mounting holes 11, relief...

Abstract

A switch cabinet slide rail and its production process are disclosed, A switch cabinet slide rail comprises a side plate connected to an inner side of that cabinet, the side plate is fixedly connectedwith a finite position bar from the top to the bottom, a track plate, a fixing plate, a slide way for the hand-car roller to be clamped between the limit strip and the track plate, a fixing cavity for the hand-car bottom table to be clamped between the fixing plate and the track plate, a plurality of mounting holes, a concession notch and a clamping hole on the surface of the side plate, and an abrasion-resistant layer on the side of the track plate facing the limit strip; The production process is as follows: S1 preheating; S2 extrusion; S3 quenching; S4 stretch straightening; S5 cutting; S6cold blanking; S7 milling; S8 Wear resistant treatment. The invention has the advantages of high abrasion resistance of the rail plate, cannot become rough after long-term use, and ensures smooth driving of the handcart.

Description

technical field [0001] The invention relates to the field of switch cabinets, in particular to a slide rail of a switch cabinet and a production process thereof. Background technique [0002] Switchgear is a kind of electrical equipment, whose main function is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The structure of the switch cabinet is simple, including a cabinet body and a hinged door, and its interior is used to install vacuum circuit breakers, disconnectors and other components. Among them, there are rollers on both sides of the bottom of the handcart vacuum circuit breaker, and the two opposite inner walls of the handcart chamber of the switch cabinet are provided with slide rails that cooperate with the rollers, which is convenient for the vacuum circuit breaker to be disassembled and moved between the working position and the test position....
