Abstract

The utility model provides a fore device of a swing type cold mill, which belongs to the techniques of manufacturing and rolling aluminum. The device comprises a framework (12), and a roller flattening device (17), cross beams (18), a nozzle beam (19) and a guide plate (20) which are fixed on the framework. The device is provided with a framework swing mechanism, wherein the upper end of a hydraulic cylinder (6) of the framework swing mechanism is hinged with the framework through an upper cross beam (9), the framework (12) is a frame structure whose left portion and right portion are symmetrical, a pin shaft (13) which is matched with an axle hole is traversed through the axle hole of the framework and the other end of the pin shaft is connected with a base (16), which forms a structure that the framework can be swung corresponding to the base around the pin shaft under the function of the hydraulic cylinder. The cold mill adopts the structural mode that the framework swing mechanism enables the framework to be swung around the pin shaft, the use is convenient and flexible, no block exists and the manufacturing, the assembly and the regulation are easy,. The assembly mode between the pin shaft in the mill and the framework of the utility model can play the functions of supporting and locating and can satisfy the requirements of flexible swing and convenient assembly and maintenance of the fore device.

Description

Device before the swing type cold-rolling mill machine

Technical field

The utility model belongs to aluminium processing rolling technique, relates generally to the preceding device of a kind of swing type cold-rolling mill machine.

Background technology

Device is the important component part of feed program before the cold-rolling mill before the cold-rolling mill machine, and it mainly acts on is the supporting guiding, adjust blank steadily enters rolling district.At present, device mostly is horizontal movable type before the machine of using on the domestic Aluminium Cold Rolling machine, promotes the front and back motion on slide rail of left and right sides frame by two hydraulic cylinders.This horizontal movable type structure has following shortcoming: at first, because machine frame at two sides is yielding, the perpendicularity of its L type chute reaches with other assembling bit position tolerance and is difficult to guarantee.Directly cause the gap between left and right sides frame and the copper coin to be difficult to guarantee that block through regular meeting, promptly its repeatable accuracy is bad when hydraulic cylinder promotes left and right sides gantry motion.Secondly, want first leveling two wood side-guides during assembling, and scraping copper coin on it, not only work difficulty is bigger, and the result of leveling is not very desirable.The 3rd, owing to there is not the depth of parallelism to adjust benchmark on this device,, increased field erected workload so when each roller center line assembles in manufactory with respect to the depth of parallelism of roll on the frame, be difficult for adjustment, thereby do not reach designing requirement.The 4th, dismounting bothers during maintenance, need expend a large amount of time, man power and material.

Summary of the invention

The purpose of this utility model promptly is to propose a kind of processing, assembling, adjustment to install before the swing type cold-rolling mill machine more simply and easily, thereby overcomes the existing in prior technology deficiency.

The utility model adopts following technical proposals to finish its invention task: device before a kind of swing type cold-rolling mill machine comprises frame and nip rolls device, crossbeam and the jet beam and the guide plate that are fixed on the frame; Be provided with the frame swing mechanism; Its upper end of the hydraulic cylinder of described frame swing mechanism is hinged by entablature and frame, described frame is symmetrical frame structure, pass in its axis hole with the bearing pin of its matched in clearance and the bearing pin other end and base are connected and composed frame can be under the hydraulic cylinder effect around the structure of the relative base swing of bearing pin.

The utility model adopts by the frame swing mechanism and makes the frame mode of frame around the bearing pin swing, and is easy to use flexible, no jam.This swing type structure is easy to processing, assembling, adjusts, as long as with boring together behind the location of the pin shaft hole on two frames, just can guarantee the precision of reference for assembling, in assembling in the processing, the connecting mode of each several part adopts the mode of pin location, bolted, and is fairly simple.When adjusting each roller depth of parallelism, be benchmark with the bearing pin simultaneously, require each roller to reach requirement with respect to the depth of parallelism of benchmark, each roller also reaches designing requirement with respect to the depth of parallelism of roll.The assembling mode of bearing pin and frame can play support, the two kinds of effects in location in the utility model, and can satisfy device flexible swinging and dismounting before the machine, needs easy to maintenance.
