Improved structure of metal plate levelling table seat

Abstract

The present invention relates to a metal plate flattening pedestal improving structure. On surface of one side of a lower (upper) supporting seat several parallel spaced grooves, and the projected portions between all the grooves are respectively equipped with several regularly-arranged recessed curved portions for receiving relative several driven idler wheels which are series-connected on a driven wheel shaft, and between the several pressure rollers positioned on the rolling metal plate and idler whells placed on lower (upper) supporting seat several supporting wheel shafts are set, and these supporting wheel shafts can be used for transferring pressure and rotation power, so that said structure can make the pressure rollers retain smooth surface state always so as to ensure the surface smoothness of the rolled metal plate.

Description

technical field [0001] The invention relates to an improved structure of a metal plate leveling platform seat, in particular to a structure that is easy to adjust the flatness and does not leave indentations on the surface of the sheet metal after rolling, so as to ensure the efficiency and quality of the leveling operation. technical background [0002] Common sheet metal leveling devices, such as figure 1 , figure 2 and image 3 As shown, it is mainly to set a rolling chamber 90 through the front and rear in the middle section of a main base body 9. The bottom side of the rolling chamber 90 is fixed with a lower seat 91, and an upper seat 92 is additionally provided above the lower seat 91. The upper seat 92 is driven by a plurality of elevating mechanisms 93 arranged on the top of the main base body 9 to move up and down, and the lower seat 91 is provided with a plurality of neatly arranged idler seats 911, each idler Seat 911 can be used for fixing two adjacent front...

Problems solved by technology

[0004] Yet above-mentioned this kind of structure, it has the following shortcoming when it is used: because each pressure roller 914 (924) needs to bear the great pressure when working, and this pressure roller 914 (924) directly contacts with each front idler wheel again. 912 (922) and rear idler 913 (923) are in contact, and the high pressure can easily cause the contact parts of the pressurized roller 914 (924) to form worn depressions with the front idler 912 (922) and rear idler 913 (923), resulting in When the metal plate 8 is rolled and flattened, indentations are left on the metal plate 8 at the same time, which may easily cause poor processing

Because a plurality of front idler wheels 912 (922) and rear idler wheels 913 (923) are respectively pivoted on a plurality of different independent idler seats 911 (921), and each idler seat 911 (921) is fixed respectively. On the lower seat 91 (upper seat 92), not only the overall processing and assembly are extremely cumbersome, but also the dimensional processing accuracy of the components (especially the lower seat 91 and the upper seat 92) is extremely high, resulting in high development costs, and after assembly. Difficult to adjust, also cause trouble during maintenance
