[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] See also Figures 1 to 3 A crimping knife die with axial rotation and adjustable shape comprises a fixed knife body 1 and an adjustable knife body 2. The fixed knife body 1 cooperates with the adjustable knife body 2 to perform crimping operations on copper and aluminum terminal blocks.

[0023] The fixed blade body 1 and the adjusting blade body 2 are respectively mounted on a fixed base 3 and a movable column 4 of the hydraulic pliers. Positioning guide columns 5 and magnets 6 are mounted on the top of the fixed blade body 1 and the bottom of the adjusting blade body 2. The magnets 6 are symmetrically distributed on both sides of the positioning guide columns 5. The positioning guide columns 5 and the magnets 6 enable the fixed blade body 1 and the adjusting blade body 2 to be precisely positioned.

[0024] The magnet 6 is embedded in the top of the fixed blade body 1 and the bottom of the adjustable blade body 2. The magnet 6 causes the fixed blade body 1 and the fixed base 3 as well as the adjustable blade body 2 and the movable column 4 to be attracted and positioned, thereby preventing the fixed blade body 1 and the adjustable blade body 2 from falling off during use.

[0025] The positioning guide column 5 is connected to the positioning hole of the fixed base 3 and the positioning hole of the movable column 4 respectively, so as to avoid the phenomenon of front-back misalignment.

[0026] A retaining edge 7 is disposed on the right side of the fixed base 3, and the retaining edge 7 is used to prevent the fixed blade body 1 from rotating, thereby playing a role of limiting.

[0027] A guide piece 8 is provided on the left side of the fixed blade body 1, and the guide piece 8 is used to guide the adjusting blade body 2, so that the fixed blade body 1 and the adjusting blade body 2 can cooperate more accurately, and at the same time prevent the adjusting blade body 2 from rotating when the movable column 4 moves, thereby affecting the crimping accuracy.

[0028] The guide piece 8 is provided with a clearance groove 9, which is used for the rotation of the adjusting blade body 2 to prevent the front and rear side edges of the adjusting blade body 2 from rubbing against the surface of the guide piece 8 when the adjusting blade body 2 rotates, so that the adjusting blade body 2 can rotate smoothly, thereby being able to perform two size changes without disassembling the fixed blade body 1 and the adjusting blade body 2.

[0029] A fixed knife crimping boss blade 10 is provided at the bottom center of the fixed knife body 1, and a fixed knife positioning boss 11 and a fixed knife positioning groove 12 are respectively provided on both sides of the fixed knife crimping boss blade 10. The two sides of the fixed knife crimping boss blade 10 are respectively connected to the left fixed knife positioning boss 11 and the right fixed knife positioning groove 12, and the left fixed knife positioning groove 12 is located between the left fixed knife positioning boss 11 and the guide plate 8.

[0030] An adjusting knife crimping opening groove 13 is provided at the top center of the adjusting knife body 2, and an adjusting knife positioning boss 14 and an adjusting knife positioning groove 15 are respectively provided on both sides of the adjusting knife crimping opening groove 13, and the two sides of the adjusting knife crimping opening groove 13 are respectively connected to the left adjusting knife positioning groove 15 and the right fixed knife positioning boss 11, and the left and right side walls of the adjusting knife body 2 are symmetrically provided with rotation grooves 16, and the rotation grooves 16 have the same function as the give way groove 9, both of which are to leave enough rotation space for the adjusting knife body 2 when rotating to avoid contact between the adjusting knife body 2 and the guide plate.

[0031] The side wall of the adjusting blade body 2 is in contact with the guide plate, so that the adjusting blade body 2 can move up and down along the guide plate, thereby ensuring the accuracy of crimping.

[0032] A bell mouth 17 is provided at the adjusting knife crimping opening groove 13 , and the edge of the bell mouth 17 crimping area plays a transition role.

[0033] The bottom of the fixed blade crimping boss blade 10 and the bottom of the adjusting blade crimping opening groove 13 are both provided with an arc surface 18, and the arc surface 18 is used for crimping.

[0034] When the crimping size needs to be changed, the boss part on the left side of the adjusting knife body 2 is moved to the give way groove 9 through the movable column 4, and then the adjusting knife body 2 is manually rotated 180° and continued to be used, so that the place where the fixed knife positioning boss 11 was originally in contact with the adjusting knife positioning groove 15 and the fixed knife positioning groove 12 was in contact with the adjusting knife positioning boss 14 becomes the place where the fixed knife positioning boss 11 is in contact with the adjusting knife positioning boss 14 and the fixed knife positioning groove 12 is spaced from the adjusting knife positioning groove 15, thereby achieving the purpose of crimping different sizes and enabling it to be converted between two sizes without disassembling the blade.

[0035] Compared with the prior art, the present invention provides an axially rotatable and adjustable crimping knife die, which can be changed into two sizes without removing the knife blade. The knife body can be directly rotated and adjusted by the provided guide piece to crimp terminals of copper and aluminum connecting wires of different sizes. There is no need to take out the knife blade. The positioning boss and the positioning groove have clearly positioned the crimping dimensions of the copper and aluminum connecting terminals to be crimped. There is no need to adjust the crimping height dimension and crimping can be performed directly. The upper and lower guide pillars and the magnet are precisely positioned, and the knife body will not fall off or be misaligned front and back. The operation is simple and efficient. The height and width dimensions of the terminals for crimping copper and aluminum connecting wires are more accurate, and the market requirements for crimping dimension accuracy can be better met.
