Embodiment Construction

[0028] See figure 1 , the present invention is a multi-functional roll installation device, including a fixed shaft 3 with a key 13, a support seat 5, a positioning sleeve 7, an oil cylinder 12, and a driving part installed on the fixed shaft 3. The two parts of the fixed shaft 3 The left bearing seat 2 and the right bearing seat 8 are respectively provided at the end, the support seat 5 and the positioning sleeve 7 are installed on the fixed shaft 3 through the key 13, the roll is installed on the support base 5, and the position corresponding to the roll is on the positioning sleeve 7. There is a positioning hole, the push rod of the oil cylinder 12 passes through the positioning hole to withstand the roll, the positioning sleeve 7 is set on the right side of the support seat 5, and the left side of the support seat 5 is provided with a bearing that can limit the axial movement of the support seat 5. The fixed set 4. The present invention replaces the original roll stand, a...

Abstract

The invention discloses a multifunctional roll mounting device which comprises a fixed shaft with keys, a supporting seat, a locating sleeve, an oil cylinder and a driving part arranged on the fixed shaft, wherein a left bearing seat and a right bearing seat are respectively arranged at the two ends of the fixed shaft; the supporting seat and the locating sleeve are both arranged on the fixed shaft through the keys; a roll is arranged on the supporting seat; the locating sleeve is provided with a locating hole corresponding to the roll; and a push rod of the oil cylinder penetrates through the locating hole to butt against the roll. By adopting the structure, the replacement of the rolls with different specifications can be realized without being dismounted after installation on a frame at one time. When the roll needs to be replaced, the original upper roll lifting mechanism is used, the whole device is lifted and rotated to a certain angle, so that the rolls with different specifications can be dismounted and replaced, and the operation is convenient. In addition, the time for replacing the rolls with different specifications can be saved, and the working efficiency is improved.The structure which is convenient to operate does not need the driving assistance, the working danger is reduced, and the personal safety of operators can be guaranteed.

Description

technical field [0001] The invention relates to a multi-functional roll installation device, in particular to a rough-formed multi-functional roll installation device used for rough-forming three- and four-stand upper rolls during installation and replacement in the production process of high-frequency straight seam welded pipes. Background technique [0002] At present, high-frequency straight seam welded pipe is a commonly used high-quality small and medium-sized steel pipe in oil and natural gas pipelines. It is widely used in gas transmission and steel structure application fields. In the production line of high frequency longitudinal welded pipe, the steel pipe forming method adopts cage forming method, TBS forming method and other methods. The production principle of the TBS forming method is to extrude the steel strip into a circle by the row of rollers arranged on both sides of the steel strip in a V-shaped space that gradually shrinks. , to ensure that the steel s...
