The head end of the plug terminal 6 is extruded by the automatic hole shrinking machine to form an outer conical surface outside the head end of the plug terminal 6, so that the guiding effect is achieved, and the head end of the plug terminal 6 is inserted into a conductive jack on a female plug end.

In order to increase the yield of the molded plug-in terminals 6, the number of the positioning seats 31 arranged on the turntable 3 is several, and every two positioning seats 31 are preferably arranged on the turntable 3 at equal intervals. After the stamping mechanism 4 is subjected to stamping forming, the turntable 3 rotates the formed plug-in terminal 6 to the position of the material taking mechanism 5, and the plug-in terminal 6 waiting for stamping is just synchronously rotated to the position below the stamping mechanism 4, so that the stamping waiting time is reduced as far as possible, and the stamping efficiency and the yield are improved.

The specific construction and feeding process of the feeding mechanism 2 are explained below:

as shown in fig. 1, the feeding mechanism 2 includes a vibrating disk 21, a feeding rail 22 and a material stopping mechanism 23, the vibrating disk 21 is driven by the vibrating disk driving mechanism to vibrate so as to convey each of the plug terminals 6 (the structure schematic diagram of the plug terminal 6 please refer to fig. 5) arranged in the feeding rail 22 to the discharging seat 231 of the material stopping mechanism 23 (the installation schematic diagram between the material stopping mechanism 23 and the feeding rail 22 please refer to fig. 2) one by one in an arrangement manner that the head section 61 of the plug terminal 6 is upward and the tail section 62 is downward; the material blocking mechanism 23 sends each plug-in terminal 6 arranged in the feeding track 22 to the positioning seat 31 of the turntable 3 one by one according to a preset time interval.

In order to improve the stamping efficiency, the time interval that the front and rear positioning seats 31 pass through the discharge hole of the material stop mechanism 23 (arranged on the discharge seat 231) is consistent with the feeding time interval of the feeding mechanism 2. Particularly, the discharge time interval of stock stop 23 is unanimous with the intermittent type nature rotation time interval of carousel 3, and after stock stop 23 gave current positioning seat 31 with the ejection of compact of spliced terminal 6, carousel 3 rotated and rotates spliced terminal 6 to press mechanism 4 below and wait for the punching press, and the next positioning seat 31 just in time rotates to the below position department of discharge seat 231 in step this moment, and stock stop follows 23 and again ejection of compact of spliced terminal to positioning seat 31.

The structure of the material blocking mechanism 23 and the intermittent discharging process of the material blocking mechanism 23 are explained as follows:

as shown in fig. 1, 2 and 3, the material stop mechanism 23 includes an upper limiting sleeve, a lower limiting sleeve and a discharging seat 231, the upper limiting sleeve and the lower limiting sleeve are mounted on the sleeve mounting frame 232, the sleeve mounting frame 232 is fixedly mounted on the mounting platform 11 of the automatic pin terminal hole shrinking machine, the discharging seat 231 is disposed at a position below the feeding track port 221 of the feeding track 22, a discharging port 2311 is formed in the discharging seat 231, the pin terminal 6 is conveyed from the feeding track port 221 of the feeding track 22 to the discharging seat 231 and then is conveyed from the discharging port 2311 to the positioning seat 31 on the turntable 3 for positioning, and the upper limiting sleeve and the lower limiting sleeve are mutually matched for movement, so that the pin terminals 6 in the feeding track 22 are conveyed to the positioning seat 31 of the turntable 3 one by one according to a predetermined time interval.

Specifically, as shown in fig. 2, the upper limiting kit includes an upper limiting cylinder 2312 and an upper limiting rod 2313, the lower limiting kit includes a lower limiting cylinder 2314 and a lower limiting rod 2315, when waiting for feeding, the upper limiting cylinder 2312 pulls the upper limiting rod 2313 to be in a contraction state, at this time, the inserting terminals 6 in the feeding track 22 are allowed to enter the discharging seat 231, and meanwhile, the lower limiting cylinder 2314 pushes the lower limiting rod 2315 to block the discharging port 2311 below the discharging bottom 231 so as to prevent discharging;

when feeding is needed, the upper limiting cylinder 2312 pushes the upper limiting rod 2313 to be in an extending state to abut against the penultimate plug terminal to block the feeding track opening 221 of the feeding track 22, so as to prevent the plug terminal 6 in the feeding track 22 from entering the discharging seat 231, the lower limiting cylinder 2314 pulls the lower limiting rod 2315 to be in a contracting state to open the discharging port 2311 of the discharging seat 231, a plug terminal 6 waiting for discharging on the discharging seat 231 falls onto the positioning seat 31 on the turntable 3 through the discharging port 2311 and is positioned, then the lower limiting cylinder 2314 drives the lower limiting rod 2315 to be in an extending state to close the discharging port 2311 of the discharging seat 231, the upper limiting cylinder 2312 pulls the upper limiting rod 2313 to be in a contracting state to open the feeding track opening 221 of the feeding track 22, so that the plug terminal 6 in the feeding track 22 moves downwards by the length dimension of one plug terminal, and the lowest plug terminal enters the discharging seat 231 and is abutted by the lower limiting rod 2315, and preparing for the next feeding.

In order to realize the positioning effect of the plug terminal on the positioning seat 31, as shown in fig. 1, a positioning insertion hole 311 is formed in the center of the positioning seat 31, and the plug terminal 6 falls down from the discharge hole 2311 of the discharge seat 231 into the positioning insertion hole 311 to be positioned on the positioning seat 31.

As a further improved embodiment, in order to ensure effective positioning of the punching process of the plug terminal 6 and ensure processing quality, as shown in fig. 4, the punching head 42 includes a punching rod 421 connected to the punching cylinder 41 and a positioning shaft 422 disposed on the punching rod 421, as shown in fig. 5, the central position of the head section 61 of the plug terminal 6 has an inner hole 611, and the positioning shaft 422 disposed on the punching rod 421 can be inserted into the inner hole 611 on the plug terminal 6 to realize punching positioning of the plug terminal 6.

In order to punch the head section 61 of the plug terminal 6 into an outer circular arc shape, as shown in fig. 4, the punch rod 421 is provided with the annular slope 4211, the annular slope 4211 surrounds the positioning shaft 422, and the punch rod 421 presses the head section 61 of the plug terminal 6 downwards through the annular slope 4211 in the downward punching process, so as to finally press the head section 61 of the plug terminal 6 into the outer circular arc shape.

After punch forming, the rotary disc 3 continues to rotate the formed plug terminals 6 to a material taking area. As shown in fig. 1, the material taking mechanism 5 includes a material taking cylinder 51 and a clamping arm 52, and when the extruded plug terminal 6 rotates to the material taking area along with the turntable 3, the material taking cylinder 51 drives the clamping arm 52 to take the formed plug terminal 6 off the positioning seat 31 and put it into the recycling container.
