Description

Terminal Crimping Device {TERMINAL PRESS APPARATUS}

The present invention relates to a terminal crimping device for producing a wire having a terminal to constitute a wire harness or the like.

A terminal crimping device for performing terminal crimping includes a flywheel driven by a motor. The flywheel rotates at a constant speed and has a crank arm attached to an eccentric pin that pivots around the pivot axis.

The crank arm vertically reciprocates the ram pivotally attached to the crank arm by the shaft pin via the connecting arm, and the connecting arm reciprocates vertically the presser integrally connected to the ram. In this way, the presser and the anvil cooperating with it press the stripped wire end of the wire into the barrel of the terminal and press it.

Such compaction apparatus is suitable for mass production because the compactor is vertically reciprocated at high speed. However, as the compactor momentarily passes through the lower dead center of the compactor (ie, does not stop at the lower dead center), the compaction operation of the compactor is instantaneous and the crimped terminal has insufficient tensile strength.

In order to solve this problem, Japanese Utility Model Registration No. 94-25911 discloses a pressing device having a pressing machine which is vertically moved by the rotation of the lead screw.

Such lead screw type compaction apparatus requires a larger apparatus to obtain a greater compaction pressure. In addition, the operating speed of the device is generally slow, which has the disadvantage of poor manufacturing efficiency.

In addition, there are disadvantages in that various types of sensors are required to determine whether the terminal is correctly crimped or manual determination is required. In addition, the screw mechanism is not suitable for fine adjustment of the crimp height.

In addition, the above-described conventional crimping device has the trouble of completely disassembling the device in order to set the working conditions of the machine according to the type or size of the terminal strip supplied.

Accordingly, an object of the present invention is to solve the above-described problem, and in particular, to provide a terminal crimping apparatus capable of controlling the terminal crimping apparatus without using a sensor.

Another object of the present invention is to provide a terminal crimping device that can easily set the position of the terminal guide.

In order to achieve the object of the present invention, according to one aspect of the present invention, the terminal crimping device having a vertical reciprocating motion to squeeze the terminal to the exposed conductive portion of the wire by operating in the vertical direction by the operating means A spring member comprising: a movable member, a pitch adjusting screw connected to the movable member, a pivot member for moving the movable member in a longitudinal direction, a compression spring for constantly applying a traction force to the pivot member, and the movable member has a spring force. There is provided a terminal crimping device comprising a terminal positioning unit having a longitudinal positioning screw for restricting movement by the.

Hereinafter, a terminal crimping apparatus according to an embodiment of the present invention with reference to the drawings will be described in more detail.

Referring to FIGS. 1 and 2, in which the terminal crimping device and the compactor are shown in an exploded view, the terminal crimping device according to the present invention includes a base plate 2 and side plates disposed on each side of the base plate 2. On the side of the side plate, a presser A operated by an electric servo motor is mounted.

Compressor A has a cylinder, pneumatically or hydraulically actuated, and a ram 14 coupled to the piston rod end of the cylinder. The ram 14 has a recess in its lower end. The recess of the ram is arranged to face an anvil 17 installed directly below the ram 14 as shown in FIGS. 3 and 4.

The side plate is also provided with a terminal positioning unit. The terminal positioning unit includes a movable member 20, a pitch adjusting screw 22 connected to the movable member, a pivot member 24 for moving the movable member 20 in the longitudinal direction, and one end of the pivot member. A compression spring 26 which is fixed to the member 24 and the other end is fixed to the side plate, and always applies traction to the pivot member, and is installed on the side plate, one end protrudes out of the side plate and the other end is movable And a longitudinal positioning screw 30 in contact with the member.

The operation of the terminal positioning unit according to the present invention will be described with reference to FIGS. 5 and 6.

After turning the lever 40 formed at one end of the terminal guide plate upward, one end of the terminal strip is pulled up to the anvil 17 with the terminal strip disposed between the terminal guide members 42.

Thereafter, the pitch adjusting screw 22 is operated to move the guide of the terminal positioning unit. Then, the longitudinal position adjusting screw 30 is operated to move the movable member. The movement of the movable member here is made by a spring 26, and the longitudinal positioning screw merely serves to prevent the movable member from moving further following the spring force.

Finally, the lever 40 is pulled downward so that the terminal strip is completely positioned on the terminal guide member, so that the preparation for the terminal crimping operation is completed.

According to the above-described configuration of the present invention, the present invention is suitable for the tank because it uses a cylinder operated by hydraulic pressure with a press. Since the ram pauses at the bottom dead center, the crimped terminal will have sufficient tensile strength.

In addition, since the terminal positioning unit made of screws is provided, the operator can easily and quickly adjust the initial conditions of the device according to the type of the terminal to be crimped.
