Abstract

The utility model discloses a kind of welded in butt weld pipe to stitch leveling plug, it includes ontology 1, and ontology 1 is equipped with venthole 2, ventilating microhole 3, sizeable diameter, the utility model structure is simple, easy to process, and interior leveling effect is fine, it is not easy to scratch inner wall of welded pipe, and can guarantee effective implementation of lower part process, make straight-seam pipes production line in long-term production operational process, achievees the effect that not only to guarantee product quality but also improve production efficiency.

Description

Welded in butt weld pipe seam leveling plug
Technical field
The utility model relates to a kind of inside welds to flatten plug, specifically a kind of welded in butt weld pipe seam leveling core Stick.
Background technique
In straight seam welded pipe production process, in the welding process, molten metal is under the effect of gravity for the tubing of forming The phenomenon that will appear the increase of position while welding tubing thickness, this thickness increment are weld reinforcement.The appearance of reinforcement will lead to conveying The energy consumption of pipeline increases.Therefore, it is necessary to use interior leveling plug to reduce welded in butt weld pipe seam reinforcement.Currently, in straight seam welded pipe In production, due to the relationship of the shape and size designing of interior leveling plug, it may go out in the actual production process of straight seam welded pipe It is existing: first is that, inner wall of welded pipe is scratched by plug, and interior protection gas is blocked by plug can not continue to protect welded tube in subsequent handling;Second is that Inner wall of welded pipe and plug both make to cannot keep cleaning, interior leveling effect is bad, directly because the metal fillings that friction generates not can be removed Seam welded tube product quality cannot be guaranteed.
Summary of the invention
The purpose of the utility model is to provide the welded in butt weld pipe seam leveling plugs that effect is flattened in a kind of raising.
The utility model, which adopts the following technical scheme that, realizes its goal of the invention, a kind of welded in butt weld pipe seam leveling core Stick rolls the ontology of section including being equipped with, roll section one end be it is non-roll leading portion, the other end be it is non-roll back segment, it is non-to roll leading portion The center of one end is equipped with screw hole, and the outer diameter of the ontology and the diameter difference of straight seam welded pipe internal diameter are the ㎜ of 0.68 ㎜~0.85, described One end of screw hole is equipped with to a section venthole for direction extension is rolled, and venthole one end is connected to screw hole, and the other end is without departing from non-stone roller The end of leading portion is pressed, ontology is evenly distributed at least one set of ventilating microhole on the non-circumference for rolling leading portion, ventilating microhole and logical Channel is equipped between stomata, one end of the channel is connected to venthole, and the other end is to rolling the inclination of section direction and connect with ventilating microhole It is logical.
The utility model is the metal fillings for removing inner wall of welded pipe and ontology and generating by friction, the center line in the channel with The angle of body axis is 48 °~60 °.
For the utility model in order to guarantee not scratch inner wall of welded pipe, the ontology both ends are equipped with rounded corner.
Due to the adoption of the above technical scheme, the utility model preferably realizes goal of the invention, and structure is simple, processing side Just, interior leveling effect is fine, and is not easy to scratch inner wall of welded pipe, can remove the gold that straight seam welded pipe inner wall and ontology are generated by friction Belong to bits, the two is made to remain clean, meanwhile, protection gas can also pass through effective implementation that ontology guarantees subsequent processing, make Straight-seam pipes production line achievees the effect that not only to guarantee product quality but also improves production efficiency in long-term production operational process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, a kind of welded in butt weld pipe seam leveling plug, the ontology 1 of section 6 is rolled including being equipped with, rolls section 6 one Leading portion 7 is rolled to be non-in end, and the other end rolls back segment 5 to be non-, and the non-center for rolling 7 one end of leading portion is equipped with screw hole 8, the ontology 1 Outer diameter 4 and the diameter difference of welded tube internal diameter be the ㎜ of 0.68 ㎜~0.85, one end of the screw hole 8, which is equipped with, prolongs to rolling 6 direction of section The venthole 2 stretched, 2 one end of venthole are connected to screw hole 8, and the other end is without departing from the non-end for rolling leading portion 7, and ontology 1 is in non-stone roller It presses and is evenly distributed at least one set of ventilating microhole 3 on the circumference of leading portion 7, channel 9 is equipped between ventilating microhole 3 and venthole 2, 9 one end of channel is connected to venthole 2, the other end to roll 6 direction of section tilt and be connected to ventilating microhole 3.
The utility model is the metal fillings for removing inner wall of welded pipe and ontology 1 and generating by friction, the center line in the channel 9 Angle with 1 axis of ontology is 48 °~60 °.
The utility model is to guarantee not scratch inner wall of welded pipe, and 1 both ends of ontology are equipped with rounded corner 10.
The outer diameter 4 of ontology 1 described in the present embodiment and the diameter difference of welded tube internal diameter are 0.8 ㎜, and the ontology 1 is rolled non- It is evenly distributed with two groups of ventilating microholes 3 on the circumference of leading portion 7, every group sets that there are three ventilating microholes 3, and three ventilating microholes 3 are at this Body 1 is non-to roll the radially even distribution of leading portion 7, the corresponding channel 9 of each ventilating microhole 3, the center line in the channel 9 with The angle of 1 axis of ontology is 60 ° in use, ontology 1 is set in welded tube, and 1 both ends of ontology are equipped with rounded corner 10, can effectively prevent Ontology 1 scratches inner wall of welded pipe, removes the metal fillings that inner wall of welded pipe and ontology 1 are generated by friction by ventilating microhole 3, the two is made to begin Keep clean eventually, meanwhile, protection gas can also pass through effective implementation that the utility model guarantees subsequent processing.
