Description

Vertical turnover device for heavy tool for steel rail forging and pressing

Technical Field

The utility model relates to a turning device, concretely relates to perpendicular turning device of heavy frock of rail forging and pressing.

Background

The two-station compound extrusion die in the existing mode is provided with an upper large die carrier tool and a lower large die carrier tool except a module, wherein the upper die carrier weighs about 9 tons, and the lower die carrier weighs about 25 tons. The up-and-down action of the press machine mainly realizes the left-and-right opening and closing of the rail web loose piece die through the upper die frame, thereby realizing different step forging and pressing die forming operations. An inclined plate connecting plate is arranged between the upper die frame and the die, is arranged on two sides of a T-shaped opening of an inner cavity of 27 degrees of the upper die frame and is connected through M24 socket head cap screws; the purchasing cost of a single upper mold frame is about 30 thousands, the period is more than 6 months, while the purchasing cost of the inclined plate is only 0.5 thousands, and the period is 7 days; the inclined plate mainly reduces the abrasion, tearing, running-in and impact on the upper die frame during the opening and closing of the die; the inclined plate parts are replaced regularly according to design requirements, otherwise, the quality of forged and formed steel rails fluctuates due to abrasion, deformation, fatigue fracture and fixation failure in long-term use, mounting screws of the steel rails are fractured, and even an upper die frame is scrapped and damaged in advance, so that the production process is stopped.

Before and after disassembling the machine in 9 months in 2020, the inclined plate is replaced in 10 months in 2018; follow end forging and pressing is invalid because of equipment running state on the one hand, and on the other hand long-term fatigue operation, the whole fracture of swash plate fastening screw two-thirds, and the fracture takes place almost for swash plate itself, goes up 27 inner chambers of die carrier body and is extruded the fracture indentation of the degree of depth about 0.5mm, and the rethread follows end forging and pressing quality rail end fluctuation unusual, can't follow mould design shaping rail spare, and it is very serious to see its influence nature. During the period from 2010 to 2020, the upper mold frame inclined plates are replaced 5 times, and the upper mold frame inclined plates are replaced 3 times from 2014 to 2020, the heel forging yield 2010-2014 is about 0.6 ten thousand heels, and the heel yield is dramatically increased to 1.5 ten thousand from 2015 to 2019.

Therefore, the installation state of the inclined plate of the upper die carrier must be fully ensured in the future, and the inclined plate needs to be replaced once in 3 months in a factory on the basis of 6-month replacement period of an original factory, so that the upper die carrier body is protected, the inspection force of the die carrier tool is increased, and the real operation state of the press machine equipment and the die is objectively inspected; and on the other hand, the working condition of the forging and forming die is stabilized, and the product quality is stabilized.

The replacement operation of the inclined plate is mainly divided into 2 parts, namely, the turnover of the upper die frame and the disassembly and assembly of the inclined plate; the turning of the upper die frame (namely the workpiece to be turned) is one of the most dangerous operations in the current profiling process; in the existing overturning mode, a crown block and manual operation mode is adopted, a steel wire rope is mainly hung on one side of a die carrier, after the crown block is lifted to the upright state of the die carrier, the crown block moves transversely and the die carrier topples over to complete the overturning action under the condition that the die carrier is not suspended; in the previous die carrier overturning process, the impact tonnage is far greater than the dead weight of a workpiece at the moment of the upper die carrier overturning, the overall up-and-down elastic fluctuation and shaking of the crown block is serious, and the surface of a steel wire rope has a strand breakage phenomenon after single overturning and needs to be replaced; the hoisting process is difficult to control effectively, major operation safety accidents such as steel wire rope breakage, crown block damage, die carrier falling and ground smashing and the like are easy to occur, and improvement is urgently needed.
