Description
Technical Field
The utility model belongs to the technical field of pipe welding and cutting, and particularly relates to a cutting and scribing tool for a groove on the section of a thick-wall steel pipe.
Background
In the field of pressure steel pipe manufacturing, the thickness of a steel plate for rolling a pipe joint (5) is relatively thick, in order to ensure the welding quality, a welding groove (51) (comprising an inner groove and an outer groove) is generally required to be formed in the section of the pipe joint before the pipe joint is butted with the pipe joint (5), the groove is generally formed by using a semi-automatic flame cutting machine, a groove contour line is generally required to be drawn before the semi-automatic flame cutting machine is used for cutting, the line is a cutting track line, and the cut groove is ensured to be qualified in size. Because the pipe coupling cross-sectional shape is special, can't accomplish the profile marking off work with general steel rule, if adopt the auxiliary point to rule with the help of appurtenance, can lead to marking off the precision not high, cause the very big waste of time and manpower. The utility model discloses an efficient and accurate line drawing tool which can be used for quickly and accurately drawing the contour line of the groove of the section of a pipe joint.
Disclosure of Invention
In order to solve the problems that the scribing accuracy is low and the time and labor are greatly wasted due to the fact that auxiliary points are adopted for scribing by means of auxiliary tools in the background technology, the utility model provides a thick-wall steel pipe section groove cutting and scribing tool; the structure is simple, the cost is low, the device is small and flexible, the device is not limited by the use place, the process of opening the pipe joint butt joint section groove of the thick-wall steel pipe is flexible and convenient, the scribing precision is high, and the contour line of the pipe joint section groove can be drawn quickly and accurately.
In order to realize the purpose, the utility model is realized by the following technical scheme: the utility model provides a thick wall steel pipe cross-section groove cutting marking tool mainly includes main slide rule, connecting screw, gyro wheel, location lock nut, main slide rule on be equipped with the bar spout, main slide rule front end is equipped with the stone pen draw-in groove, connecting screw pass through location lock nut adjustable mounting on the bar spout of main slide rule, but the gyro wheel passes through the bearing free rotation and installs on connecting screw.
The positioning locking nut is provided with an arc-shaped plate which is convenient for adjusting stress.
The tail end of the main sliding ruler is provided with a hanging hole.
The utility model has the beneficial effects that:
the utility model has simple structure, low cost, small size, flexibility, no limitation of use places, flexibility and convenience in the process of opening the groove of the butt joint section of the pipe joint of the thick-wall steel pipe, high marking precision, capability of quickly and accurately drawing the contour line of the groove of the section of the pipe joint, capability of ensuring that the size of the cut groove is qualified and improving the cutting precision.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.
The utility model discloses a cutting and scribing tool for a section groove of a thick-wall steel pipe, which mainly comprises a main sliding ruler 1, a connecting screw rod 2, a roller 3 and a positioning locking nut 4, wherein the main sliding ruler 1 is provided with a strip-shaped sliding chute 11, the front end of the main sliding ruler 1 is provided with a stone pencil clamping groove 12, the connecting screw rod 2 is adjustably installed on the strip-shaped sliding chute 11 of the main sliding ruler 1 through the positioning locking nut 4, and the roller 3 can be freely and rotatably installed on the connecting screw rod 2 through a bearing; simple structure, with low costs, small and exquisite flexibility does not receive the place of use restriction, and it is nimble convenient at the pipe coupling butt joint cross section groove of thick wall steel pipe open system in-process, and the marking off precision is high, can be fast accurate draw pipe coupling cross section groove contour line, can ensure that the groove size of cutting out is qualified, improves cutting accuracy.
The positioning locking nut 4 is provided with an arc-shaped plate 41 which is convenient for adjusting stress, so that the positioning locking nut is convenient to disassemble, assemble and adjust.
The tail end of the main sliding rule 1 is provided with a hanging hole 13, and the main sliding rule can be used for hanging management when not used, so that the management is convenient.
The working process is as follows:
loosening the positioning locking nut 4, enabling the connecting screw rod 2 to slide in the strip-shaped sliding groove 11, adjusting the connecting screw rod 2 to a target position, locking through the positioning locking nut 4, fixing the connecting screw rod 2 to ensure that the distance from the roller 3 to the stone pen clamping groove 12 is consistent, enabling the roller 3 to be attached to the outer wall surface of the pipe joint 5, placing the stone pen in the stone pen clamping groove 12, pressing through fingers, enabling the roller 3 to be attached to the outer wall surface of the pipe joint 5 to rotate for a circle, and enabling the stone pen to mark a cutting track line on the end surface of the pipe joint 5.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
