Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a cross-rolled two-roll piercer adopting a cast-welded structure, and to solve the problems of bulky equipment of the all-cast piercer and poor stress state of the main frame of the all-welded piercer In order to solve the problem, a closed frame-type frame was manufactured by adopting a uniformly stressed casting structure, and a non-main force-bearing body was manufactured by taking advantage of the advantages of lightness and beauty of the welded structure, which not only makes the main force-bearing frame good in rigidity and high in strength, Moreover, the overall equipment is light in weight and flexible in movement

Embodiment Construction

[0017] Such as figure 1 , 2 As shown in , 3 and 4, a cross-rolling two-roll piercer adopting a cast-welded structure includes: a main frame 1, two roll devices 2 placed in the main frame, placed on the left and right sides of the main frame 1 The two guide plate devices 3, the guide plate locking device 4, the guide plate adjustment device 5, and the pressing device 6 and the pressing device 7 for respectively adjusting the distance between the two roller devices.

[0018] The main body frame 1 is a casting, which eliminates irregular parts, leaving only a closed frame structure, which improves the casting process; because there is no surrounding redundant material connected to it, it can be designed as a pure The eight-beam and four-column frame body is an ideal stress-receiving body, which specially bears the rolling pressure transmitted by the two rolls 2-1 and 2-2.

[0019] The two roller devices 2 described are installed in the main body frame 1 and are slidably matched...

Abstract

The invention provides a diagonal rolling double-roller puncher having a cast-weld structure and relates to hot rolling seamless tube equipment. The puncher of the invention comprises a main frame, two roller devices arranged in the main frame, two guide boards arranged on the side wall of the main frame, a guide board locking unit and a guide board regulating unit, wherein the main frame is a closed frame casting and the guide board, the guide board locking unit and the guide board regulating unit are respectively welded pieces. The invention solves the problem that a full-casting puncher isheavy and the stress state of an all-welded puncher main frame is inferior. The closed frame is manufactured by using a uniformly stressing cast structure. The secondary force bodies are manufacturedby using the advantages that the welding structure is light and beautiful. The frame has high rigidity and strength and the whole device is light and flexible to move.

Description

technical field [0001] The invention relates to equipment for hot-rolling seamless steel pipes, in particular to a cross-rolling two-roll piercer. Background technique [0002] Existing cross-rolling two-roll piercing machine, in addition to the main frame, is also connected with a guide plate device, and its structure can be divided into two types: one is the full casting type, and the other is the full welding type. The all-cast structure is to cast all the structures that can be fixedly connected with the frame (including the main frame, the guide plate device, the locking and adjusting device of the guide plate, etc.) --The material of the guide plate device is redundant and wasteful, and due to the complex structure, the casting process is poor, which affects the quality of the equipment. The all-welded structure is to weld all the structures that can be fixedly connected with the frame into a whole. Although the structure is light and handy, and the appearance is neat...
