Problems solved by technology

[0003] The terminal molds in the prior art can only use preformed terminal strips, and the tails of the terminals are pre-bent into a U shape, and the U-shaped tails are higher than the plane of the terminal strips, resulting in a significant reduction in winding density and low capacity of the terminal disk; at the same time, the terminal strips are It is easy to get stuck when winding and unwinding, and each layer needs to be separated by a partition such as paper tape or plastic film, which increases the difficulty of winding and causes waste of paper tape

[0066] Embodiment 2. Single-channel terminal crimping system and crimping method

[0067] like Figure 5 As shown, a single-channel terminal crimping system includes the terminal machine main part 4, the single-channel mold assembly 1 described in Embodiment 1, the feeding assembly 5, the installation base plate 6 and the controller, the terminal machine main part 4 and The mold assembly 1 is installed on the installation base plate 6, the punch of the terminal machine main part 4 is connected with the hammer head mounting plate 15 of the mold assembly 1, the feeding assembly 5 is installed on the body base plate of the terminal machine main part 4, and the feeding assembly Part 5 contains a group of feeding channels 7, the terminal channel 3 corresponds to the feeding channel 7, and the controller is used to control the operation of the terminal crimping system.

[0068] like Image 6 and Figure 7As shown, the feeding assembly 5 includes a group of feeding channels 7, a f...

Embodiment 3

[0079] Embodiment 3, double channel mold assembly

[0080] The mold assembly in this embodiment is basically the same as the mold assembly in Embodiment 1. For the sake of simplicity, only the differences will be described below.

[0081] like Figure 8 As shown, a double-channel mold assembly 1 includes a lower die base 11, a lower template 12, an upper template 13, an upper back plate 14, and a hammerhead mounting plate 15, and the lower mold base 11 is equipped with a lower template 12, and the hammerhead mounting plate Install the upper back plate 14 and the upper formwork 13 in sequence under 15 steps, and a guide structure 2 is provided between the lower formwork 12 and the upper formwork 13; two sets of terminal channels 3 are provided in the middle of the mold assembly. Two sets of terminal channels can be crimped with different terminal strips. The two sets of terminal passages in Figure 9 are used for crimping fork 4 terminal strips and pin 1 terminal strips respec...

Abstract

The invention discloses a mold assembly, a terminal crimping system and a crimping method. One or more than one group of terminal channels are arranged in the mold assembly; and each group of terminal channels comprises a terminal tail folding tool group, a thrust tool group and a crimping tool group. The terminal crimping system comprises the mold assembly. According to the terminal crimping method, a flat terminal strip is crimped through the terminal crimping system; and molding of a terminal tail, thrusting of a terminal and the terminal strip and crimping of the terminal and an electric wire are finished through once stamping. By the crimping method, three functions of molding the terminal tail, thrusting the terminal and the terminal strip and crimping the terminal and the electric wire can be finished through once stamping; the processing process is simplified; the processing time is shortened; the non-preformed flat terminal strip can be utilized; the risk of clamping stagnation during winding and emptying is removed; interlayers of a paper bag and the like are omitted; and the capacity of a terminal plate is increased.

Description

technical field [0001] The invention relates to the field of electric wire processing, in particular to a mold assembly, a terminal crimping system and a crimping method. Background technique [0002] In the wire processing industry, wire making equipment often requires crimping terminals on the ends of wires. In the prior art, the crimping between the terminal and the electric wire is to send the wire whose insulation layer has been stripped into the tail of the pre-formed terminal, jog the punch, and the punch pushes the upper knife group and the stationary lower knife group. Squeeze the tail of the terminal to complete the crimping of the terminal and the wire, while the severing knife cuts the terminal from the strip. [0003] The terminal molds in the prior art can only use preformed terminal strips, and the tails of the terminals are pre-bent into a U shape, and the U-shaped tails are higher than the plane of the terminal strips, resulting in a significant reduction i...
