Description of drawings

Below, referring to the accompanying drawings, the above and other objects, features and advantages of the present invention will be apparent to those skilled in the art from the detailed description of the present invention.

Fig. 1 is the structural representation of the utility model pneumatic puncture crimping machine;

Fig. 2 is a partial sectional view of the upper and lower dies 10 in Fig. 1;

FIG. 3 is an exploded schematic view of the upper and lower molds 10 in FIG. 1 .

Detailed ways

Please refer to Fig. 1, the pneumatic piercing crimping machine of the present utility model comprises a base 5, and the frame 7 that is fixed on it, is provided with a cylinder 11 on the frame 7 above the base 5, passes through one side The air pipe 2 is connected to a pneumatic driving part, the pneumatic driving part is composed of a gas meter 4, a regulating valve 3 and a waterproof valve 12, and a slider seat 9 and a solenoid valve 8 are fixed on the side frame 7, and on the base 5 Upper and lower molds 10 are arranged between the top of the mold and the frame 7. The upper and lower molds 10 are composed of two parts. The upper punch 21 is fixed to the upper frame 7 through a slider seat 9, and the lining plate 25 and the terminal fixing plate 24 are fixed on the base 5. In addition, the A power supply box (not shown) is also arranged in the base 5 , and a switch 6 for controlling the power supply is arranged on a side of the base 5 .

The structure of the upper and lower molds will be introduced below with reference to Figures 2 and 3. As mentioned above, the upper and lower molds include two parts that are opposite up and down. From the exploded schematic diagram given in Figure 3, it can be seen that the lower mold includes a liner 25, and the center of the liner 25 Offer a groove, there is a terminal fixing plate 24 on the top of the lining plate 25, the shape of this plate is a rectangular frame with one side opening, the branch line clamping groove 26 is fixedly arranged on the opening side of the terminal fixing plate 24 on the lining plate 25, and its locking Slot side up. The upper mold consists of two parts, the front and the rear. The front side in the figure is the foot-wrapping punch 21, and the rear crimping punch 22. The size and shape of the two punches are similar. The difference lies in the foot-wrapping punch 21 and the crimping punch. The functions of the punch below the line punch 22 are different, and the punch arc of the wrapping punch 21 is larger than that of the line punch 22 . The upper mold is fixed on the slider seat 9, and can slide left and right along with the slider seat 9 to determine the matching position with the lower mold.

The working principle and usage of the pneumatic piercing and crimping machine of the present utility model will be described in detail below. First turn on the switch 6 of the power box located in the base 5 to turn on the solenoid valve 8, then turn on the air pressure switch regulating valve 3, adjust the air valve to 6-8KG, check whether the adjusting screw 1 is loose, and put the terminal with one side up into the terminal Push the inside of the fixing plate 24 tightly, then put the cable core wires into the branch line slot 26 according to the chromatographic arrangement specified in the work instruction book, and then press the switch 6 with both hands. The core wire is snapped into the slot of the terminal 23, and at the same time, the foot-wrapping punch 21 and the crimping punch 22 spring back to their original positions; take out the terminal 23 with one side connected to the core wire and put the other side up into the terminal fixing plate 24, Also put the core wire into the slot of the terminal 23, and press the switch 6 with both hands to complete the crimping on the other side of the terminal.

By adopting the pneumatic piercing and crimping machine of the utility model, one employee can independently complete a finished connecting wire. This equipment has changed from electric to pneumatic, greatly reducing production costs and labor resources, and improving the working environment. This equipment is small in size, can change the mold type at will, adjust the pressure, the foot is firm, the contact performance is good, the operation is simple, the production speed is fast, the equipment performance is stable, the maintenance is convenient, the service life is long, the safety is low, and the cost is low.

The above embodiments are only for illustrating the utility model, rather than limiting the utility model, and those skilled in the art can also make various transformations or changes without departing from the spirit and scope of the utility model Therefore, all equivalent technical solutions should also belong to the category of the present utility model and should be defined by each claim.
