Embodiment 1

[0036] Example 1, as Figure 1-5 As shown, the present invention provides an auxiliary device for scribing before beveling of a steel plate, including a plate A1 for laminating the top surface 3 of the steel plate, and a plate B2 for laminating the thickness surface 4 of the steel plate, the plate A1 and the plate A1 B2 is a one-piece structure, the outer long side of the plate A1 coincides with the upper groove line on the top surface 3 of the steel plate, and the outer long side of the plate B2 coincides with the upper groove line on the thickness surface 4 of the steel plate.

[0037] The invention has the advantages of simple structure, scientific and reasonable design, and convenient use. , to ensure the quality of the steel plate beveling, further ensure the quality of the weld, used for fast and convenient scribing, improve work efficiency, simple and practical, with low material cost, simple and efficient use.

[0038] According to the groove angle required by the pro...

Embodiment 2

[0039] Example 2, as Figure 1-5 As shown, the present invention provides an auxiliary device for scribing before beveling of a steel plate, including a plate A1 for laminating the top surface 3 of the steel plate, and a plate B2 for laminating the thickness surface 4 of the steel plate, the plate A1 and the plate A1 B2 is a one-piece structure, the outer long side of the plate A1 coincides with the upper groove line on the top surface 3 of the steel plate, and the outer long side of the plate B2 coincides with the upper groove line on the thickness surface 4 of the steel plate. Plate A1 and plate B2 form an included angle of 90° with each other.

[0040] On the basis of Embodiment 1, this embodiment 2 provides a more preferred structure between the plate A1 and the plate B2, specifically: the plate A1 and the plate B2 form an included angle of 90° with each other. This design can make the plate A1 and the plate B2 adhere more closely to the base metal steel plate, and ensure...

Embodiment 3

[0041] Example 3, as Figure 1-5 As shown, the present invention provides an auxiliary device for scribing before beveling of a steel plate, including a plate A1 for laminating the top surface 3 of the steel plate, and a plate B2 for laminating the thickness surface 4 of the steel plate, the plate A1 and the plate A1 B2 is a one-piece structure, the outer long side of the plate A1 coincides with the upper groove line on the top surface 3 of the steel plate, and the outer long side of the plate B2 coincides with the upper groove line on the thickness surface 4 of the steel plate. Plate A1 and plate B2 are formed by integral bending of color steel tiles.

[0042] On the basis of Embodiment 1, this embodiment 3 provides a more preferred structure of the plate A1 and the plate B2, specifically: the plate A1 and the plate B2 are integrally formed by bending color steel tiles. Such a design, easy to manufacture, and strong practicability. The device is formed by bending and proces...

Abstract

The invention discloses and provides an auxiliary device and an auxiliary method for scribing before steel plate beveling. The technical problem that in the prior art, the steel plate beveling error is large, and consequently the welding seam quality is not ideal is solved. The auxiliary device comprises a plate A and a plate B which are of an integrated structure, the long edge of the outer side of the plate A coincides with the groove line on the top surface of the steel plate, and the long edge of the outer side of the plate B coincides with the groove line on the thickness surface of the steel plate. According to the auxiliary method, a plate A, a plate B, a plate C and a plate D are machined to be attached to cutting lines according to the positions of the groove cutting lines, the surface of a base metal steel plate is cleaned up, the auxiliary device is arranged in the thickness direction of the steel plate to be closely attached, and the slate pencil and the auxiliary device are moved in the length direction of the steel plate to obtain the positions of the two cutting lines; and repeating the operation to obtain all required cutting line positions, and then using a flame cutting machine to align to the cutting lines for cutting. The device is formed by bending and processing the color steel tile, is used for quickly and conveniently grooving and scribing the steel plate, improves the working efficiency, is simple and practical, and ensures the grooving quality of the steel plate.

Description

technical field [0001] The invention belongs to the technical field of steel plate processing equipment, and in particular relates to an auxiliary device and an auxiliary method for scribing before beveling of a steel plate. Background technique [0002] In order to ensure the penetration of the weld on the workpiece, when using arc welding to weld thick materials, it should also be considered to open a groove at the joint. There are four basic forms of grooves commonly used in manual arc welding: I-shaped groove, V-shaped groove, U-shaped groove and X-shaped groove. When welding thick plates with T-shaped or fillet joints, K-shaped grooves can also be opened. bevel. [0003] Depending on the thickness of the welded plate, the groove types of the butt joint are as follows: [0004] 1. I-shaped groove (or flat joint): It is used for welding with a thickness of 1-6mm. In order to ensure the penetration of the welded parts, a gap of 0-2.5mm should be left at the joint. [00...
