Working principle: in this embodiment, the present invention further provides a method for using the terminal crimping machine, including the following steps:
firstly, a foot switch 8, a hydraulic cylinder 11, an electric push rod 28 and a servo motor are respectively and electrically connected with a control box 3 through leads, then a worker places one end of a cable of a terminal to be crimped on a supporting plate 10, pushes the cable of the terminal to be crimped between a fixed die holder 5 and a movable die holder 6 along the supporting plate 10, enables the rear end of a terminal sleeved on the cable to be abutted against a butting net frame 31, and further can avoid the condition that the terminal is excessively fed when being fed through the arrangement of a blocking assembly;
secondly, after an uncrushed terminal on a cable wire stretches into a space between an upper crimping mechanism and a lower crimping mechanism, at the moment, a hydraulic cylinder 11 is started through a foot switch 8 to drive a connecting seat 26 connected with a stabilizing block 12 to descend, the descending connecting seat 26 drives a movable die holder 6 to descend, the stability and the deviation prevention effect of the movable die holder 6 during descending can be improved under the action of a guide post 13, when the movable die holder 6 descends, a fixed clamping block 14 in the movable die holder 6 can abut against a movable clamping block 15 in the fixed die holder 5 to descend obliquely, meanwhile, a fixed clamping block 14 in the fixed die holder 5 can reversely abut against a movable clamping block 15 in the movable die holder 6 to ascend, and as the sliding paths of the two movable clamping blocks 15 are obliquely moved towards the terminal, the two movable clamping blocks 15 can synchronously face the terminal to perform crimping operation, the terminal abuts between the two fixed clamping blocks 14, and then the two fixed clamping blocks 14 and the movable clamping blocks 15 cooperate, so that synchronous crimping operation on six end faces of the terminal is realized;
step three, before the movable clamping block 15 moves in place due to the abutting force, at the moment, a small amount of hydraulic oil in a hydraulic cavity can be extruded into the thrust through a liquid supply pore canal under the action of the stabilizing column 17 and the sealing plug plate 23 in the guide assembly, when the hydraulic oil enters the thrust, the sealing push plate 24 can be pushed to move outwards in the thrust cavity under the action of the liquid thrust, and the shaping clamping plate 27 is pushed to extrude and dent the end faces of the terminals, which are preliminarily pressed on two sides, for the second time, so that an anti-slip groove is conveniently stamped on the press-connection surface of the primary molded terminals, the anti-deflection effect of the terminals and copper wires in the cable after press-connection can be further improved, and the anti-loosening performance of the terminals after press-connection is improved; the method has the advantages that only two of six crimping surfaces of the terminal can be subjected to local secondary small-amplitude pressing operation, and the situation that the connection between the cable and the terminal is unbalanced or broken due to excessive applied force is effectively avoided;
step four, when the crimping operation of the tail end is carried out on the terminal on the cable, at the moment, the electric push rod 28 is synchronously started to drive the shaping clamping plate 27 to move towards the annular piece end of the terminal, the outer wall of the terminal annular piece can be extruded into a corrugated surface shape through the two shaping clamping plates 27 which are relatively close to each other, the anti-slip effect of the terminal annular piece after installation is improved, the anti-slip surface is stamped on the annular piece part of the terminal, and meanwhile, the terminal annular piece which is subjected to bending deformation can be flattened, so that the terminal crimping is facilitated, and meanwhile, the terminal body is rapidly shaped;
step five, after the crimping of the terminal on the cable wire is completed, the hydraulic cylinder 11 is started to lift up with the movable die holder 6 and the crimping mechanism inside the movable die holder 6, when the movable die holder 6 lifts up, the movable clamping blocks 15 at the moment can return rapidly under the action of the return springs 19, at the initial stage of returning of the movable clamping blocks 15, when the movable die holder 6 lifts up slightly, the pressing groove blocks 22 at the moment retract under the action of the return springs 25 and the sealing push plates 24, so that the pressing groove blocks 22 can be kept flush with the vertical pressing surfaces of the movable clamping blocks 15 again after being used, and then the two movable clamping blocks 15 can also finish the resetting synchronously along with the continuous lifting of the movable die holder 6, and wait for the crimping operation of the terminal next time;
step six, after the movable die holder 6 is lifted, then take down the cable conductor of crimping good terminal, if need to clear up the top surface rear end of frame 2, drive lead screw 32 through start servo motor 33 and carry out reciprocal positive and negative rotation, then make the movable die holder drive L type pole 34 and clean horizontal pole 35 and carry out the back and forth cleaning operation to the interior bottom surface of frame 2, be convenient for clean the broken bits into the sediment mouth, then the broken bits drop inside collecting box 9 through the sediment mouth.
