Abstract
A split elastic damping body of a high-speed wire rolling mill is characterized in that a large end head of a balancing device is connected with a cushion block into a whole by adopting a movable connecting structure, so that the sum of the length of the connected cushion block and the length of one side of the large end of the balancing device meets a length value of a use requirement; the movable connecting structure is a threaded connecting structure. The advantage is that the following combinations can be used: 1. a combination of a large end head of a balancing device and a cushion block is used; 2. the cushion block is disassembled, and the large end of the balancing device is directly used, so that the assembling requirement of the minimum roll diameter can be met; the device has low manufacturing cost, simple assembly, practicality and reliability; effectively prolongs the service life of the roller and reduces the roller changing time.
Description
Technical Field
The utility model relates to a high-speed wire closed type rolling mill elastic damping body in the steel industry, in particular to split type high-speed wire rolling mill elastic damping body.
Background
The elastic damping bodies originally designed by a high-speed closed type rolling mill in a rod line section bar factory of Liuzhou steel sharps company have three types of YG550, YG450 and YG400, and the stroke is 50 mm. The minimum roll diameters of the elastic damping bodies of various types of rolling mills which can be used in the three rolling stands are respectively 550mm, 445mm and 370 mm. In order to improve the utilization rate of the roller, reduce the cost of the roller and create more production benefits for each pair of rollers, the elastic damping bodies of the three types of rolling mills are required to be used in three types of rolling mill frames until the minimum roller diameters are respectively 520mm, 430mm and 360 mm. The originally designed elastic damping body of the rolling mill cannot meet the stroke requirement. The following problems are specifically present: 1. when the three rollers are used to the diameters of less than 550mm, 445mm and 370mm, the stroke of the elastic damping body piston rod of the rolling mill with the original design size is shortest, and the elastic damping body piston rod cannot be shortened continuously; 2. the existing three rollers can not be used continuously after the diameters of the rollers are 550mm, 445mm and 370 mm; 3. the original design depth of the installation opening of the elastic damping body on the base of the rolling mill is deepened with great difficulty, and dust and iron oxide scales easily enter the installation opening to be accumulated and blocked. The problems result in low utilization rate of the roller, increased storage, management and maintenance of the roller and low total yield of the roller.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a cost of manufacture is low, and the assembly is simple, practical, reliable, can satisfy the split type altitude rolling mill elastic damping body that minimum roll diameter assembly required.
The utility model discloses a solution is such:
a split elastic damping body of a high-speed wire rolling mill divides a high-pressure balancing device into a large end and a cushion block, the large end of the balancing device is connected with the cushion block into a whole by adopting a movable connecting structure, so that the sum of the length of the cushion block after connection and the length of one side of the large end of the balancing device is equal to the length of the original balancing device, the length value meets the use requirement, and the high-pressure bearing capacity of the balancing device is kept unchanged.
The more specific technical scheme also comprises the following steps: the movable connecting structure is a threaded connecting structure.
Further: the threaded connection structure is a boss with a diameter reduced on the large end side of the balancing device, external threads are machined on the edge of the boss, the cushion block is of a structure with a sinking platform, internal threads are machined on the inner wall of the sinking platform, and the cushion block is connected with the large end of the balancing device into a whole through the threaded connection structure.
The utility model has the advantages that:
(1) the following combinations may be used: 1. a combination of a balancing device and a cushion block is used; 2. only the large end of the balancing device is used, so that the assembly requirement of the minimum roll diameter can be met;
(2) the manufacturing cost is low, and the assembly is simple, practical and reliable;
(3) after the damping bodies are redesigned, the depths of the rollers corresponding to the elastic damping bodies of the YG550, YG450 and YG400 rolling mills which can be used more than once are respectively 30mm, 15mm and 10mm, and the single turning amounts of the three rollers are respectively about 10mm, 7mm and 7mm, so that the three rollers (one set) can be ensured to be turned more than once (namely used more than once), the steel passing amount of the whole set of rollers used once is 24000 tons at least, and the benefit of the one set of rollers used once can be created more than 24000 x 4000 yuan/ton =9600 ten thousand yuan at least according to the average 4000 yuan/ton of unit price of a high-speed wire product; in addition, the design effectively prolongs the service life of the roller and reduces the roller changing time (labor intensity of workers).

Detailed Description
As shown in fig. 1, 2 and 3, the boss with the diameter reduced on the side of the large end head 1 of the balancing device is provided with an external thread on the edge of the boss, the cushion block 2 is of a structure with a sinking platform, an internal thread is processed on the inner wall of the sinking platform, and the cushion block 2 is connected with the large end head 1 of the balancing device into a whole through a threaded connection structure, so that the sum of the length of the connected cushion block 2 and the length of the large end head 1 side of the balancing device is equal to the length of the original balancing device, the length value meets the use requirement, and the high-pressure bearing capacity of the balancing device is kept unchanged.
When in use, if the length of the large end 1 of the balancing device and the cushion block 2 meets the use requirement, the cushion block 2 and the large end 1 of the balancing device are screwed together, so that the whole length meets the use requirement; if the length of the big end 1 of the balancing device and the cushion block 2 does not meet the use requirement, the cushion block 2 is taken down, and the big end 1 of the balancing device is directly used, so that the length of the big end meets the use requirement.
By adopting the design of the structures shown in fig. 1, 2 and 3, the depths of the rollers corresponding to the elastic damping bodies of the rolling mills of the YG550, the YG450 and the YG400 models can be used more than 30mm, 15mm and 10mm respectively, and the single turning amounts of the three rollers are about 10mm, 7mm and 7mm respectively, so that the three rollers (one set) can be turned at least once (namely used more than once), the steel passing amount of the whole set of rollers used once is 24000 tons at least, and the efficiency of the one set of rollers used once can be created more than 24000 x 4000 yuan/ton =9600 ten thousand yuan at least according to the average 4000 yuan/ton of unit price of a high-speed wire product; in addition, the design effectively prolongs the service life of the roller and reduces the roller changing time.
