Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a mechanism for improving the service life of an OTP die feeding claw and a cable processing die. Background Art

[0002] The OTP mold is a mold used for wire harness processing, which is mainly divided into OTP straight mold, OTP horizontal mold, OTP single-particle mold, OTPU mold and other types. When producing cables / wire harnesses, it is usually necessary to crimp the cables and terminals together. In order to achieve this production purpose, a mold is usually set up in the terminal machine, and the terminals and cables are crimped together through the mold. The terminals are usually produced by stamping. Before the terminals are crimped, the terminals and the strips are connected together. The material claws constantly move the strip holes on the strips, thereby continuously conveying the terminals. However, when the material claws convey the terminal strips, the needle tip of the material claws will contact the bottom plate, which is easy to wear, and the service life of the material claws is short. At the same time, when the needle tip of the material claws is worn, the conveyed strips will be offset, affecting the feeding accuracy.

[0003] For example, Chinese patent application number: CN201922327400.4 A terminal feeding assembly specifically discloses "the lower end of the pin is thinner and is used to insert into the positioning hole of the terminal strip. The terminal strip is in the shape of a strip, on which terminals are integrated, and a positioning hole is provided. After the pin is inserted into the positioning hole of the terminal strip, the terminal strip can be pushed forward." This design causes the tip of the pin to wear faster and has a shorter life. When the pin tip is severely worn, the transported strip will be offset, affecting the feeding accuracy.

[0004] For example, please refer to Figure 5 As shown: The material-dispensing claw moves the hole of the material strip to realize the loading of the material strip. When the material-dispensing claw is transferring the terminal material strip, the needle tip of the material-dispensing claw will contact with the bottom plate, which is easy to wear and has a short service life. When the needle tip of the material-dispensing claw is worn too much, the transported material strip will be offset, affecting the loading accuracy. Utility Model Content

[0028] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the present utility model, which is a mechanism for improving the service life of the feeding claw of an OTP mold.

[0029] Among them, when the pushing claw 20 retracts, the main body part 21 slides upward along the first inclined surface 31, so that the pushing claw 20 can be lifted along the first inclined surface 31 of the first limiting block 30, and the tip 24 of the pushing claw 20 is separated from the feeding seat 10 accordingly, thereby reducing the wear of the pushing claw 20, improving the service life of the pushing claw 20, and being beneficial to ensuring the feeding accuracy.

[0030] The present application provides a mechanism for improving the life of the feeding claw of an OTP mold, including a feeding seat 10 and a limiting seat 13, wherein the limiting seat 13 is arranged on the feeding seat 10, and a feeding channel 14 is formed between the limiting seat 13 and the feeding seat 10; a first limiting block 30 is arranged on the feeding seat 10, and the first limiting block 30 has a first inclined surface 31; a material-moving claw 20 includes a main body 21 and a claw 23; the main body 21 slides back and forth on the first inclined surface 31; the claw 23 extends to the side of the feeding channel 14, and the claw 23 moves the feeding material in the feeding channel 14 forward. The limiting seat 13 can be arranged on the feeding seat 10 by screws, and a feeding channel 14 is formed between the limiting seat 13 and the feeding seat 10, and the material belt 52 is restricted in the feeding channel 14 (at this time, the terminal 53 and the material belt 52 are connected together), so that the terminal 53 and the material belt 52 will not deviate. When feeding, the material-discharging claw 20 moves forward, the main body 21 moves downward along the first inclined surface 31, and the material-discharging claw 20 penetrates into the material belt 52 hole of the material belt 52, and pushes the material belt 52 forward at the same time. When the material-discharging claw 20 retreats, the main body 21 moves upward along the first inclined surface 31, and the material-discharging claw 20 can be lifted along the first inclined surface 31 of the limit block, and the needle tip 24 of the material-discharging claw 20 is separated from the feeding seat 10, thereby reducing wear, improving the service life of the material-discharging claw 20, and ensuring the feeding accuracy.

[0031] Preferably, a first groove 11 is provided on the feed seat 10; the claw 23 can extend into the first groove 11. The claw 23 is provided with a needle tip 24, and the needle tip 24 can penetrate into the hole of the material belt 52. The first groove 11 has a certain depth. The material belt 52 spans across the first groove 11, and the first groove 11 can reserve a certain escape space for the needle tip 24. The claw 23 can press the material belt 52 into the notch position of the first groove 11, and the needle tip 24 of the claw 23 passes through the hole of the material belt 52 and partially extends into the first groove 11. The needle tip 24 will not rub against the inner wall of the first groove 11, so that the needle tip 24 will not be worn, and the material belt 52 will not deviate when feeding.

[0032] Preferably, the first limit block 30 is provided with a narrow and long mounting hole 32, through which the first fastener 33 passes, and fastens the first limit block 30 to the feeding seat 10. The first fastener 33 may be a screw or a latch. The number of the mounting holes 32 is not specifically limited. The first fastener 33 cooperates with the mounting hole 32 to conveniently adjust the mounting position of the first limit block 30, and the layout is more flexible.

[0033] Preferably, the material pushing claw 20 is arranged on the driving mechanism 40, and the driving mechanism 40 includes a slide rail 42, a slider 43, a first spring 44, and a mounting bracket 45; the output end of the first driving source is connected to the slider 43 and drives the slider 43 to slide on the slide rail 42; the mounting bracket 45 is hinged to the slider 43, and the first spring 44 pulls the first end of the mounting bracket 45; the material pushing claw 20 is arranged at the second end of the mounting bracket 45. The first driving source can be a cylinder or a servo motor. The driving rod 41 of the first driving source drives the slider 43 to slide on the slide rail 42. The first spring 44 pulls the first end of the mounting bracket 45, so that the claw portion 23 can swing downward, facilitating the needle tip 24 to penetrate into the hole of the material tape 52. Working principle of the driving mechanism 40: 1. The first driving source pushes the slider 43, and the main body portion 21 moves downward along the first inclined surface 31. The elastic force of the first spring 44 enables the material pushing claw 20 to smoothly penetrate into the hole of the material tape 52, and at the same time advances the material tape 52. 2. The first driving source pulls the slider 43, and the main body portion 21 moves upward along the first inclined surface 31. The first inclined surface 31 causes the material pushing claw 20 to withdraw from the hole of the material tape 52. Repeat step 1, and the needle tip 24 penetrates into another hole of the material tape 52.

[0034] Preferably, a second groove 12 is provided on the material feeding seat 10, the first limiting block 30 has a limiting convex block 34, and a part of the material extends into the second groove 12, and the limiting convex block 34 presses on the material. A second limiting block 15 is further provided on the material feeding seat 10; the second limiting block 15 is located on the upstream side of the first limiting block 30 and can press the material. A part of the terminal 53 extends into the second groove 12, the limiting convex block 34 presses the material tape 52, and the second limiting block 15 presses the material tape 52. In this way, the movement trajectories of the terminal 53 and the material tape 52 are both restricted, so the feeding accuracy is more guaranteed, and neither the terminal 53 nor the material tape 52 will deviate. The material can be a terminal and a material tape, or other materials.

[0035] Preferably, a second inclined surface 22 is provided on the side of the main body portion 21 close to the first inclined surface 31, and the first inclined surface 31 and the second inclined surface 22 are parallel. The main body portion 21 is in a stepped shape, which is more beneficial for layout and is more compact and convenient to assemble. Since the first inclined surface 31 and the second inclined surface 22 are parallel, the main body portion 21 can slide back and forth on the first inclined surface 31 more smoothly without jamming problems.
