Description
Technical Field
The utility model relates to a cutting tool bar with a replaceable blade, and belongs to the field of workover tools.
Background
In the existing well repairing operation, the problem that the drilling tool is blocked or even blocked in the oil pipe frequently occurs, and the oil pipe needs to be cut off under the condition that the drilling tool cannot be blocked greatly so as to facilitate subsequent recovery operation. At present, a special downhole tool is required to be used for cutting the small-diameter oil pipe, a blade is easy to wear in the cutting process, a cutter bar is required to be replaced frequently, and the operation cost is increased. Therefore, it is important to design a cutting tool bar with replaceable blades, and the cutting efficiency can be improved and the operation time can be saved by replacing clamping blades.
Disclosure of Invention
The utility model provides a cutting tool bar with a replaceable blade, which solves the problems of high tool cost and large required inventory space caused by the fact that the tool bar head of the existing cutting tool bar is not replaceable.
The technical scheme adopted for solving the technical problems is as follows:
the cutting tool bar with the replaceable blade comprises a front end tool bar head and a rear end tool bar handle, wherein a blade clamping groove is formed in the upper end face of the tool bar head, a fastening groove is formed in the upper end face of the tool bar head, a long screw hole is formed in the lateral end face of the tool bar head, and an inclined plane is formed in the lateral end face of the tool bar head. The upper end face of the cutter bar handle is provided with a through hole, the rear end face of the cutter bar handle is provided with a screw hole along the axial direction of the through hole, and the rear end face of the cutter bar handle is provided with an arc.
The cutting tool bar with replaceable blades of the utility model is characterized in that: the screw aperture of the long screw hole is M4; the aperture of the through hole is 6mm; the screw hole diameter of the screw hole is M4.
The cutting tool bar with replaceable blades of the utility model is characterized in that: the thickness of the blade clamping groove is 3mm, and a semicircular groove with the radius of 1mm is processed in the blade clamping groove; the thickness of the fastening groove of the cutter head is 3mm.
The cutting tool bar with replaceable blades of the utility model is characterized in that: the length of the screw hole of the cutter bar handle is 8.9mm; the end face of the cutter bar handle is processed with an arc diameter of 16mm.
Compared with the prior art, the utility model has the following beneficial effects:
(1) The cutting tool bar with the replaceable blade adopts an assembly structure, when oil pipes with different sizes are cut, only the blade with the corresponding size is required to be replaced, and the whole cutting tool bar is not required to be replaced when the blade is required to be replaced after the blade is worn, so that the tool use cost is greatly saved.
(2) The cutting tool bar with the replaceable blade is convenient to use, quick to install, and superior to a welding tool bar in use effect, machining quality and the like.
Drawings
FIG. 1 is a front view of a replaceable insert cutting tool holder of the present utility model;
FIG. 2 is a schematic view of the cutting insert holder of the present utility model with replaceable inserts;
in the figure: 1. a cutter bar; 1-1, a blade clamping groove; 1-2, fastening grooves; 1-3, a long screw hole; 1-4, through holes; 1-5, screw holes; 1-6, a semicircular groove; 1-7, arc.
Detailed Description
The utility model is further described with reference to the drawings and detailed description which follow:
the first embodiment is as follows: the utility model discloses a cutting tool bar with replaceable blades, which is shown in the accompanying drawings 1 and 2, wherein the cutting tool bar 1 with the replaceable blades comprises a tool bar 1 head and a tool bar 1 handle, a blade clamping groove is formed in the upper end face of the tool bar 1 head, a fastening groove 1-2 is formed in the upper end face of the tool bar 1 head, a long screw hole 1-3 is formed in the lateral end face of the tool bar 1 head, and an inclined plane is formed in the lateral end face of the tool bar 1 head. The upper end face of the cutter bar 1 handle is provided with a through hole 1-4, the rear end face of the cutter bar 1 handle is provided with a screw hole 1-5 along the axial direction of the through hole 1-4, and the rear end face of the cutter bar 1 handle is provided with an arc 1-7.
The second embodiment is as follows: when the cutter is used, the cutter blade is placed in the cutter blade clamping groove 1-1, and the long screw hole 1-3 of the cutter bar 1 is matched with the screw thread of the screw to fasten the cutter blade and the cutter bar 1 head. The cutter bar 1 passes through the through hole for positioning through the screw rod, the screw passes through the screw hole for limiting the axial rotation of the cutter bar 1 along the through hole, and the cutter bar is arranged on the front end surface of the cutting tool in the downhole oil pipe. The downhole in-tubing cutting tool spreads the cutter bar 1 circumferentially by transmitting torque through rotation of a screw driven through the through-bore 1-4.
And a third specific embodiment: as shown in the accompanying drawings 1 and 2, when the utility model is used, the screw hole diameter of the long screw hole 1-3 is M4; the aperture of the through holes 1-4 is 6mm; the screw hole diameter of the screw holes 1-5 is M4. By the design, the screw is convenient to penetrate through the long screw holes 1-3 and the screw holes 1-5, so that the blade and the cutter bar 1 are convenient to connect and detach. Other components and connection relationships are the same as those of the first or second embodiment.
