AI Technical Summary
When the fixing screw holes at the four corners of the traction end face of the tension reducer frame are damaged, the magnetic drill lacks a fixed position, making it difficult to enlarge the hole.
Design a hole-expanding fixture for a tension reduction machine frame, including a pad and a positioning component, which are fixed to the tension reduction machine frame using a fixing rod and a handle, providing sufficient flat area for magnetic drilling.
This allows the magnetic drill to be securely fixed on the tension reduction machine frame, facilitating hole enlargement operations.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of steel pipe processing, and particularly relates to a stretcher leveler rack reaming tool. BACKGROUND
[0002] In the process of processing seamless steel pipes, a stretcher leveler needs to be used.
[0003] For example, Fig. 1-2 Each of the four corners of the traction end face of the stretcher leveler rack is provided with a draw hook 91, specifically: a base 92 is fixed at the corner of the traction end face, two screw holes 93 are arranged on the base 92, and the draw hook 91 is fixed on the base 92 through the cooperation of the fixing bolt 94 and the screw hole 93. In this way, the stretcher leveler can be moved by pulling the draw hook 91.
[0004] The edge behind the base 92 has a process through hole 99, and the process through hole 99 is parallel to the traction end face of the stretcher leveler rack.
[0005] The recessed area between the two draw hooks 91 is provided with a hydraulic pipe 98.
[0006] Because the force (torque) of the movement of the stretcher leveler is transmitted through the fixing bolt 94 and the screw hole 93, sometimes the fixing bolt 94 will fall off from the screw hole 93 (that is, the internal thread of the screw hole 93 is damaged), at this time, the screw hole 93 needs to be reamed, and after reaming, a screw sleeve is screwed on, the inner and outer sides of the screw sleeve are provided with threads, the external thread cooperates with the hole wall thread of the new screw hole 93, and the internal thread cooperates with the fixing bolt 94, so that the repair of the screw hole 93 is completed.
[0007] The difficulty lies in that: when the screw hole 93 is reamed, a magnetic drill is generally used, and the traction end face of the stretcher leveler rack has the base 92 at the four corners and the boss 96 for installing the turnover hole 95 in the middle, so that the basic surface 97 of the traction end face is very small, and the magnetic drill has no place to be fixed. UTILITY MODEL CONTENTS
[0008] The technical problem to be solved by the utility model is: how to design a stretcher leveler rack reaming tool to facilitate the fixation of the magnetic drill.
[0009] The technical scheme of the utility model is specifically as follows:
[0010] A stretcher leveler rack reaming tool, comprising a backing plate and two positioning pieces; the backing plate comprises a first backing plate and a second backing plate, the first backing plate and the second backing plate are fixed together through a fixing rod, the outer end portions of the first backing plate and the second backing plate are both fixed with a convex column, and the convex column is exposed on the outer side of the backing plate; the positioning piece comprises a positioning plate, one end of the positioning plate is provided with a positioning hole, the other end of the positioning plate is welded with a fixed nut, the fixed nut is in threaded cooperation with a resisting bolt, and a strip-shaped hole is arranged on the positioning plate on the inner side of the fixed nut.
[0011] The fixed rod is a door type.
[0012] A handle is fixed on the fixed rod.
[0013] Compared with the prior art, the technical effect of the utility model is that when the utility model is fixed on the tension-reducing machine rack, the outer surfaces of the base, the first pad plate and the second pad plate are on a plane, and the area is large, so that the magnetic force of the magnetic force drill can be fixed by magnetic force adsorption.

[0021] The utility model will be described in detail below in combination with the drawings and the specific implementation.
[0022] As Fig. 3-4 A tension-reducing machine rack reaming tool, comprising a pad plate piece and two positioning pieces.
[0023] As Fig. 3 The pad plate piece comprises a first pad plate 11 and a second pad plate 12, the first pad plate 11 and the second pad plate 12 are fixed together through a fixed rod 10, the outer end portions of the first pad plate 11 and the second pad plate 12 are all fixed with convex columns 13, and the convex columns 13 are exposed on the outer side of the pad plate.
[0024] As Fig. 4 The positioning piece comprises a positioning plate 20, one end of the positioning plate 20 is provided with a positioning hole 21, the other end of the positioning plate 20 is welded with a fixed nut 23, the fixed nut 23 is in threaded cooperation with a resisting bolt 24, and the positioning plate 20 on the inner side (the side close to the positioning hole 21) of the fixed nut 23 is provided with a strip-shaped hole 22.
[0025] As Fig. 5 In order to avoid the hydraulic pipe (see the mark 98 in the attached Fig. 2 The fixed rod 10 is a door type.
[0026] In order to facilitate holding, the fixed rod 10 is fixed with a handle 14. Fig. 5
[0027] The working principle is as follows:
[0028] During processing, the thickness of the first and second pads 11 and 12 matches the thickness of the base 92, and the length of the pad matches the thickness of the tension-reducing machine frame.
[0029] In use, the following steps are included: Fig. 1-7
[0030] S1, a straight rod 88 is first arranged in the process through hole 99 of the base 92, and both ends of the straight rod 88 are exposed.
[0031] S2, the first and second pads 11 and 12 are placed on the base surface 97 between the base 92 and the boss 96, see Fig. 6 .
[0032] S3, one side is fixed, specifically, see Fig. 7 , the positioning hole 21 is sleeved on the protruding column 13, the strip-shaped hole 22 is sleeved on the straight rod 88, the bolt 24 is screwed tightly, and the first and second pads 11 and 12 are tightly attached to the base surface 97.
[0033] S4, the other side is fixed, see step S3.
