Abstract
The utility model relates to an extrusion device for welded pipe welding. The extrusion device comprises an extrusion roller supporting frame, a fixed extrusion roller and a movable extrusion roller, wherein the fixed extrusion roller is fixedly arranged on the extrusion roller supporting frame through the two ends of a shaft, the movable extrusion roller is arranged above the fixed extrusion roller, the movable extrusion roller is arranged on a slide block on the extrusion roller supporting frame through two ends of a shaft, and the slide block can move up and down along the vertical direction in a sliding chute in the extrusion roller supporting frame; and the extrusion device is characterized in that shafts on the outer sides of the two end faces of the movable extrusion roller are provided with an adjusting draw plate, and an adjusting screw rod is arranged on the adjusting draw plate. According to the utility model, one of the two extrusion rollers is fixedly arranged and the other extrusion roller is movable; the diameter of a corresponding extrusion hole between the extrusion rollers is adjusted through an adjusting screw rod so as to adjust a joint of a steel belt to an appropriate position, the width requirement for the steel belt is not high, therefore, the quality of welding is ensured, and the extrusion device is convenient and simple to operate and use.
Description
Technical field
The utility model relates to a kind of tube-welding device, relates in particular to a kind of tube-welding extrusion machine.
Background technology
In the Welded Pipe Production Process of prior art, general steel band constant speed is by two extruded holes that compression roller forms in the welding pressurizing unit, when steel band process extruded hole, steel band is being squeezed roller extruding and when forming the welded tube circular section, the steel band interface obtains high-frequency welding, existing welded tube unit production line nearly all is to adopt fixed adjustment welding pressurizing unit, namely two compression rollers connect with reverse screw mandrel, rotary screw rod, compression roller tightens up or unclamps, and according to the diameter of intending producing welded tube, regulates corresponding extruded hole diameter between the compression roller by the forward or reverse screw mandrel, in case adjust complete after, in Welded Pipe Production Process, generally can not adjust again corresponding extruded hole diameter between the compression roller, even adjustment is also very inconvenient, therefore, overlap welding appears in interface when steel band is wider, when steel band is narrower, and the slit that interface can occur not welding again, so that welding tube quality does not reach the requirement of national standard, affect quality and the qualification rate of welded tube.
The utility model content
The purpose of this utility model is to provide a kind of tube-welding extrusion machine that can solve the prior art defective.
The purpose of this utility model is achieved through the following technical solutions; A kind of tube-welding extrusion machine, comprise compression roller bracing frame, fixed press roller and movable compression roller, the fixed press roller is fixedly mounted on the compression roller bracing frame by the two ends of axle, movable compression roller is positioned at the top of fixed press roller, the two ends of movable compression roller by axle are installed on the slide block on the compression roller bracing frame, this slide block can vertically move up and down in the chute on the compression roller bracing frame, it is characterized in that, on the axle in the movable compression roller both ends of the surface outside adjusting arm-tie is installed also, at the adjusting arm-tie adjusting screw mandrel is installed.
Further, described adjusting screw mandrel is ball screw.
Further, described adjusting screw mandrel passes through motor-driven.
The utility model compared with prior art its advantage is: the utility model is with a fixed installation in two compression rollers, another can be movable, adjust corresponding extruded hole diameter between the compression roller by an adjusting screw mandrel, the steel band interface is adjusted to suitable position, do not need again steel band to be carried out strict width requirement, guaranteed the quality of welding, easy for operation simple.
Description of drawings
Fig. 1 is tube-welding extrusion machine structural representation of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 1 is tube-welding extrusion machine structural representation of the present utility model, as shown in Figure 1, a kind of tube-welding extrusion machine of the present utility model, comprise compression roller bracing frame 1, fixed press roller 3 and movable compression roller 2, fixed press roller 3 is fixedly mounted on the compression roller bracing frame 1 by the two ends of axle, movable compression roller 2 is positioned at the top of fixed press roller 3, the two ends of movable compression roller 2 by axle are installed on the slide block 5 on the compression roller bracing frame 1, this slide block 5 can vertically move up and down in the chute on compression roller bracing frame 16, also be equipped with on the axle in the movable compression roller 2 both ends of the surface outside and regulate arm-tie 4, at adjusting arm-tie 4 adjusting screw mandrel 7 is installed, adjusting screw mandrel 7 in the present embodiment can be common screw mandrel, also can be ball screw, the upper end of regulating screw mandrel 7 connects the motor 8 that is fixedly installed on the compression roller bracing frame 1, and motor 8 drives regulates the screw mandrel rotation.
The utility model is with a fixed installation in two compression rollers, another can be movable, owing to can move up and down by slide block 5 and chute 6 between movable compression roller 2 and the compression roller bracing frame 1, be converted into moving up and down of adjusting arm-tie 4 by the rotation with motor 8, and then the moving up and down of adjusting activity compression roller 2, thereby can realize very easily adjustment to extruded hole diameter between the compression roller, the steel band interface is adjusted to suitable position, do not need again steel band to be carried out strict width requirement, guaranteed the quality of welding, easy for operation simple.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
