Description

Technical Field

[0001] This invention belongs to the field of metallurgical equipment technology, and relates to the adjustment device and adjustment method for the forming roller of a pressure welding machine. Background Technology

[0002] Currently, cold forming and welding technology for structural steel uses a single-channel forming process, with the forming rollers being essentially passive, resulting in a simple equipment structure. Waste-heat bending forming and welding technology for structural steel, on the other hand, involves directly utilizing the residual heat after hot-rolled strip is cut and bent into shape using rollers, making it more environmentally friendly. However, regardless of whether it's cold forming or hot forming welding technology, the forming roller adjustment devices in welding machines used to produce open or closed structural steel of different specifications or shapes cannot adjust the tilt angle and eccentricity of the forming channel. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a forming roller adjustment device and adjustment method for a pressure welding machine, so as to adjust the tilt angle and eccentricity of the forming channel.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The forming roller adjustment device for a pressure welding machine includes a flat roller assembly and a vertical roller assembly. The flat roller assembly includes two drive shafts arranged parallel to each other and supported on an upper support seat and a lower support seat, respectively. Both the upper and lower support seats are connected to lifting devices to allow them to rise and fall relative to the machine frame. The vertical roller assembly includes two vertical roller shafts arranged in a V-shape with adjustable spacing from the two drive shafts. Forming sleeves are fitted on both vertical roller shafts and the two drive shafts to form a U-shaped forming channel. The forming sleeves on one drive shaft are two axially adjustable flat roller sleeves, and the forming sleeves on the other drive shaft are two axially adjustable inclined roller sleeve assemblies arranged opposite each other. The inclined roller sleeve assembly includes a bearing, an inclined roller sleeve fixedly connected to the outer ring of the bearing, an inwardly concave spherical connecting sleeve fixedly connected to the inner ring of the bearing, and an eccentric sleeve matching the spherical connecting sleeve. The eccentric sleeve is fitted on the drive shaft and its axial position is adjustable. A locking inclined sleeve is detachably connected to the inner side of the eccentric sleeve. Several adjusting bolts are spaced apart on the locking inclined sleeve to adjust the tilt angle and eccentricity of the bearing relative to the eccentric sleeve.

[0006] Optionally, a movable bushing is provided between the eccentric sleeve and the drive shaft, and the movable bushing is connected to an axial drive device to drive it to move axially along the drive shaft.

[0007] Optionally, a movable bushing is provided between the eccentric sleeve and the drive shaft. A double-row tapered roller bearing is provided on the outer side of the eccentric sleeve. The inner ring of the double-row tapered roller bearing is fixedly connected to the movable bushing, and the outer ring of the double-row tapered roller bearing is fixedly connected to the movable bearing housing. The movable bearing housing is connected to an axial drive device to drive it to move axially along the drive shaft.

[0008] Optionally, the axial drive device includes a lead screw and nut pair driven by a rotary drive device. The nut of the lead screw and nut pair is fixedly connected to a movable bearing seat and slidably connected to a guide rail arranged parallel to the drive shaft. The guide rail is mounted on a corresponding support seat.

[0009] Optionally, each of the two drive shafts is provided with two sets of forming sleeves arranged at intervals, and the frame is provided with two sets of vertical roller assemblies. The two sets of vertical roller assemblies and the two sets of forming sleeves on the two drive shafts form a double forming channel.

[0010] Optionally, the threaded end of the adjusting bolt passes through a strip-shaped connecting through hole in the locking sleeve and is threadedly connected to a threaded hole in the inner ring of the bearing or in the spherical connecting sleeve.

[0011] Optionally, a pad is provided between the eccentric sleeve and the spherical connecting sleeve.

[0012] The forming roller adjustment method for a pressure welding machine provides a forming roller adjustment device as described above. By adjusting the tilt angle and eccentricity of the spherical connecting sleeve fixedly connected to the inner ring of the bearing relative to the eccentric sleeve, the tilt angle and eccentricity of the inclined roller sleeve fixedly connected to the outer ring of the bearing relative to the eccentric sleeve are adjusted, thereby realizing the adjustment of the eccentricity and tilt angle of the inclined roller sleeve relative to the drive shaft.

[0013] Optionally, adjusting the tilt angle and eccentricity of the inclined roller sleeve includes the following steps: first, loosen all adjusting bolts, then rotate the spherical connecting sleeve to a predetermined angle, and then fix the spherical connecting sleeve onto the locking inclined sleeve using adjusting bolts.

[0014] Optionally, adjusting the eccentricity of the inclined roller sleeve further includes the following steps: setting a shim between the spherical connecting sleeve and the eccentric sleeve, and adjusting the thickness of the shim to adjust the eccentricity of the inclined roller sleeve relative to the drive shaft.

[0015] The beneficial effects of this invention are as follows: by adjusting the tilt angle and eccentricity of the spherical connecting sleeve fixedly connected to the inner ring of the bearing relative to the eccentric sleeve, the tilt angle and eccentricity of the inclined roller sleeve fixedly connected to the outer ring of the bearing relative to the eccentric sleeve are adjusted, thereby realizing the adjustment of the eccentricity and tilt angle of the inclined roller sleeve relative to the drive shaft. This solves the problem that the existing forming roller adjustment device of the pressure welding machine cannot adjust the tilt angle and eccentricity of the forming channel, thus improving the forming efficiency.
