Detailed Description

The present invention will be described in further detail with reference to specific examples.

Examples:

as shown in fig. 2 to 3, an in-mold automatic riveting device of the present invention includes a central riveting mold and a plurality of feeders (a first feeder 21 for providing riveted objects 11 and a second feeder 22 for providing riveted objects 12) disposed around the riveting mold, wherein the riveting mold includes a lower mold 3 and an upper mold 4, a feeding surface of the feeder is located between the lower mold 3 and the upper mold 4, the lower mold 3 is pivoted with a rotating disk 31 through a vertical rotating rod 311, the rotating rod 311 is driven by a power device 32 capable of controlling a rotation angle, the upper mold 4 is provided with a pressing plate 41 capable of driving the rotating disk 31 to descend, and blanking riveting dies 312 (two in this case) having the same number as the feeders are uniformly distributed on the rotating disk 31 around a shaft, and the blanking riveting dies 312 have a blanking function and a riveting function. The riveting die is in fact a progressive die with stations arranged on a circumference. The specific working principle is as follows: the rotary disk 31 is stopped at the initial position, so that one blanking riveting die 312 is positioned below the material belt of the riveted object 11 sent by the first feeder 21, and the other blanking riveting die 312 is positioned below the material belt of the riveted object 12 sent by the second feeder 22; then, the blanking riveting cutting die 312 below the material belt of the riveting object 11 is clamped for the first time, the material belt of the riveting object 11 is cut off from the material belt and directly falls on the blanking riveting cutting die 312; then the power device 32 drives the rotary disk 31 to rotate 180 degrees so as to enable the two blanking riveting dies 312 to replace, the cut rivet 11 reaches the lower part of the material belt of the rivet 12, the rivet is also sent to the riveting dies, and the two dies are riveted while being clamped. Therefore, riveting of the former product and cutting of the riveted object 11 of the latter product are completed by one mold closing, the process is continuous, the manufacturing is quick, and the positioning is convenient. Therefore, the rotary disc with the blanking riveting cutting die is used for riveting, so that the riveting efficiency is improved, the riveting positioning is facilitated, and the riveting precision is improved.

As shown in fig. 2 and 3, the feeder has a first feeder 21 and a second feeder 22, the first feeder 21 and the second feeder 22 are arranged in parallel, and two blanking riveting dies 312 arranged at 180 ° with each other are arranged on the rotating disc 31. Typically, there are at least two parts to be riveted, so at least two feeders are used to complete the riveting operation. However, if there are more complex components of a particular construction, it is also contemplated that more feeders and stations may be used.

As shown in fig. 2, the lower die 3 is provided with a movable punch 33 capable of floating, and the upper side of the movable punch 33 abuts against the lower surface of the rotary disk 31. The movable beating rod 33 is used as an auxiliary for stripping, and when the die is opened, the movable beating rod 33 can provide a force on the periphery of the rotary disc 31, so that the rotary disc 31 is jacked up.

As shown in fig. 2, the top of the movable driving lever 33 is horizontally pivoted with a roller 331 contacting the rotating disk 31. When the mold is opened, the rotary disk 31 rotates around the longitudinal axis and moves relative to the movable beating rod 33, and the roller 331 can generate smaller rolling friction force to enable the mechanism to operate more smoothly.

As shown in fig. 2, the lower die 3 is provided with a lower stopper post 34 for guiding the position of the rotating disk 31 and the belt during mold clamping, and the upper die 4 is provided with an upper stopper post 42 for guiding the position of the rotating disk 31. The upper and lower stop posts 42, 34 allow the strip to be in the proper relative position with the rotary disk 31, ensuring that the product is cut and riveted in place.

As shown in fig. 2 and 3, an induction block (not shown) is provided at an edge of the rotary disk 31, and an inductor 5 for detecting a position of the induction block is provided at one side of the caulking mold, and the inductor 5 is used for controlling a rotation angle of the power device 32. The normal operation of the device depends on the rotation precision of the rotating disc 31, coarse positioning can be more accurate by sensing through the sensor 5, and thus the die can be crashproof by positioning by using the limiting column 42 and the lower limiting column 34.

What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
