Abstract
The utility model relates to a combined steel pipe forming roller. The combined steel pipe forming roller comprises a roller body and rotating shafts, wherein the roller body comprises a plurality of roller units connected in a spliced mode in the axial direction, each rotating shaft is arranged in the middle of the corresponding roller unit in a sleeved mode, the rotating shafts and the roller units are connected through keys, threads are arranged at the two ends of each rotating shaft, and each rotating shaft is sleeved with a fastening nut matched with the threads. The combined steel pipe forming roller is simple in structure and reasonable in design, production cost can be effectively controlled while the stability of the whole roller in the working process is guaranteed, when some portion of the roller is broken or has other quality problems, the single roller unit can be replaced, replacement of all the roller units is not needed, cost is greatly reduced, and meanwhile effective operation of the device can be guaranteed.
Description
Technical field
The utility model relates to the thick molding roller of a kind of steel pipe, is specifically related to a kind of combined steel pipe molding roller.
Background technology
In existing steel pipe forming roll, conventionally be all integral structure, but in actual application, exist many problems for roll: be 1. easy to cause local fragmentation for the roll of integral structure, thereby cause whole roll to be scrapped, replacement cost is too high; 2. the roll of integral structure making quality cannot be guaranteed, and what need at diverse location is different quality requirements, and integral structure adopts same material and surface treatment, does not possess professionalism; 3. for the improvement of traditional roll structure, its connected mode is carried out to new innovation and design simultaneously, can more efficientlyly assemble and coordinate and fix.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of combined steel pipe molding roller of the high in cost of production problem that can effectively improve traditional roll is provided.
For achieving the above object, the technical scheme of taking is:
A kind of combined steel pipe molding roller, comprise roll body and rotating shaft, described roll body comprises the roll unit of multiple spliced connections vertically, the middle part of roll unit is set with rotating shaft, rotating shaft is all connected by key with roll unit, two ends in rotating shaft are also provided with screw thread, are set with the nut that tightens up mating with screw thread in rotating shaft.
Between described roll unit and roll unit, be connected location by detent and positioning boss.
The end of described rotating shaft is flat, and offers bar-shaped trough, is provided with the clamping bolt at bar-shaped trough inner part for fixed placement in the end of rotating shaft.
Adopt technique scheme, obtained beneficial effect is:
The utility model is simple in structure, reasonable in design, in ensureing the stability of the whole roll course of work, can effectively carry out the control of production cost, the quality problems such as fragmentation occur in roll a part is, can carry out the replacing of single roll unit, and without carrying out whole replacements, greatly reduce cost, can ensure effective operation of equipment simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of roll unit matching.
Sequence number in figure: 1 is that roll unit, 2 is that rotating shaft, 3 is that detent, 5 is that positioning boss, 6 is that bar-shaped trough, 7 is clamping bolt for tightening up nut, 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Referring to Fig. 1, Fig. 2, a kind of combined steel pipe molding roller of the utility model, comprise roll body and rotating shaft 2, described roll body comprises the roll unit 1 of multiple spliced connections vertically, the middle part of roll unit 1 is set with rotating shaft 2, rotating shaft 2 is all connected by key with roll unit 1, two ends in rotating shaft 2 are also provided with screw thread, in rotating shaft 2, be set with mate with screw thread tighten up nut 3, between described roll unit 1 and roll unit 1, be connected location by detent 4 and positioning boss 5, detent 4 mates spacing with positioning boss 5.
The end of described rotating shaft 2 is flat, and offers bar-shaped trough 6, is provided with the clamping bolt 7 at bar-shaped trough 6 inner parts for fixed placement in the end of rotating shaft 2.
The utility model is simple in structure, reasonable in design, in ensureing the stability of the whole roll course of work, can effectively carry out the control of production cost, the quality problems such as fragmentation occur in roll a part is, can carry out the replacing of single roll unit, and without carrying out whole replacements, greatly reduce cost, can ensure effective operation of equipment simultaneously.
