[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A copper tube cutting device comprises two symmetrically arranged copper tube placement platforms 1, on which matching copper tubes are arranged; a cutting platform 2 is arranged between the two copper tube placement platforms 1, on which a reciprocating mechanism 3 is arranged, and on which cutting knives 4 are arranged at both ends of the reciprocating mechanism 3, respectively; and a cutting knife groove 11 is arranged on the copper tube placement platform 1 at a position corresponding to the cutting knife 4.

[0022] In the present invention, the steel pipe is pushed from front to back by the staff, and can also be pushed by a pushing mechanism. This is common knowledge in the field, and technical personnel in this field can set it according to actual conditions; the reciprocating mechanism moves left and right, and is used to cut the copper pipes on the copper pipe placement tables on the left and right sides: improve work efficiency and reduce labor costs.

[0023] The reciprocating mechanism 3 includes a moving crossbar 31 and a reciprocating mechanism 32 . The moving crossbar 31 performs reciprocating motion under the drive of the reciprocating mechanism 32 . The cutting blade 4 is rotatably mounted at both ends of the moving crossbar 31 .

[0024] In the present invention, for example, the cutting knife is a circular cutting knife, the circular cutting knife is rotatable, the axis of the circular cutting knife is vertically arranged to the moving cross bar, the center of the circular cutting knife is connected to the output shaft of the motor, the rotation of the motor drives the circular cutting knife to rotate, and the circular cutting knife cooperates with the cutting knife groove on the copper tube placement table to cut the copper tube; the motor is not shown in the accompanying drawings, but the motor can be fixedly installed on the rear side of the end of the moving cross bar or other positions. This is common knowledge in the field, and technical personnel in this field can set it according to actual conditions.

[0025] The reciprocating mechanism 32 includes a forward driving component and a counter-reciprocating driving component. The forward driving component includes a disc 3211 rotatably mounted on the cutting table 2. The disc 3211 is provided with a first push rod 3212 perpendicular to the disc surface of the disc 3211. The moving cross bar 31 is connected with a first transmission rod 3213. The first push rod 3212 pushes the first transmission rod 3213 driven by the disc 3211, and the first transmission rod 3213 drives the moving cross bar 31 to move rightward. The counter-reciprocating driving component cooperates with the disc 3211 to drive the moving cross bar 31 to move leftward.

[0026] In the present invention, it should be noted that a motor can be installed at the center of the disc, or a motor can be embedded in the cutting table (not shown in the figure) to drive the disc to rotate. The axis of the disc is vertically arranged, and the first push rod is arranged on the upper surface of the disc; the first transmission rod is T-shaped, and the short side of the first transmission rod is arranged parallel to the moving cross bar, and the short side of the first transmission rod is fixedly connected to the moving cross bar, and the end of the long side of the first transmission rod extends forward to the disc; when the disc rotates clockwise under the action of the motor, there must be a period of time so that the first push rod on the disc contacts the first transmission rod and pushes the first transmission rod to move to the right, so that the moving cross bar moves to the right.

[0027] The reciprocating drive assembly includes a second push rod 3221 perpendicular to the surface of the disc 3211, and a second transmission rod 3222 is connected to the moving cross bar. The second push rod 3221 pushes the second transmission rod 3222 driven by the disc 3211, and the second transmission rod 3222 drives the moving cross bar 31 to move leftward.

[0028] The second push rod 3221 is symmetrically arranged with the first push rod 3212; the second transmission rod 3222 is L-shaped, the corner of the second transmission rod 3222 is connected to the axis of the cutting table 2, the second transmission rod 3222 is rotatably connected to the cutting table 2, the second transmission rod 3222 includes a first connecting rod 32221 and a second connecting rod 32222 that are integrally connected, the first connecting rod 32221 is provided with a waist-shaped hole, the moving cross bar 31 is provided with a third push rod 323, and the third push rod 323 can be slidably installed in the waist-shaped hole; the end of the second connecting rod 32222 is arranged along the disc 3211 and cooperates with the second push rod 3221.

[0029] In the present invention, the angle between the first connecting rod and the second connecting rod is less than 90 degrees. Since the second push rod is symmetrically arranged with the first push rod, when the first push rod contacts the first transmission rod and pushes the first transmission rod, the moving cross rod moves to the right and drives the third push rod to move to the right synchronously, so that the second transmission rod rotates clockwise around the turning angle, and the second push rod does not affect the movement of the second transmission rod; when the first push rod reaches the last contact point with the first transmission rod, that is, when the first push rod reaches the pushing limit of the first transmission rod, the second push rod symmetrical to the first push rod contacts the second transmission rod and pushes the second transmission rod to move upward, so that the second transmission rod rotates counterclockwise around the turning angle, and at this time, the first connecting rod moves to the left, and the moving cross rod moves to the left under the action of the waist-shaped hole of the third push rod and the first connecting rod.

[0030] Rollers 22 are respectively disposed at the front and rear sides of the end of the moving cross bar 31 . The roller shaft 21 of the roller 22 is fixedly mounted on the cutting table, and the outer surface of the roller 22 matches with the moving cross bar 31 .

[0031] The cutting table 2 is provided with a limiting groove matched with the moving cross bar 31 .

[0032] In the present invention, Figure 2-3 As shown, the limit groove is 3 / 4 of the circle of the steel pipe, and there is a height difference between the two sides of the limit groove. The moving cross bar is limited by the limit groove to prevent it from moving away from the cutting knife. Figure 1 As shown, the roller shaft of the roller is fixedly arranged on the cutting table, and the roller is used to increase the movement reliability of the moving cross bar, so that the movement is smooth. At the same time, the setting of the roller can further prevent the moving cross bar from moving forward and backward.

[0033] The cutting table 2 is fixedly connected with a limiting member 23 which matches with the moving cross bar 31 .

[0034] In the present invention, for example, the limit piece is U-shaped, the opening of the limit piece is set downward, and the two ends of the moving cross bar are respectively provided with through grooves matching the limit piece. The two ends of the limit piece are respectively fixedly connected to the cutting table on the front and rear sides of the moving cross bar. By setting the limit piece, the moving cross bar is prevented from moving quickly and falling out upward during cutting.

[0035] In the present invention, any copper tube is manually pushed to a cutting position, and the cutting is performed by the circular cutting knives at both ends of the moving crossbar.
