Description

Technical Field

[0001] The utility model relates to the technical field of core rods for knurling machines, in particular to a core rod mechanism for loading and unloading equipment for knurling machines. Background Art

[0002] Since the knurled product is hollow, it is necessary to use a core rod to install it into the inner cavity of the product before knurling to prevent the product from being deformed by the pressure of the knurling machine during the knurling process. After the knurling is completed, it is necessary to use a core rod removal mechanism to remove the core rod from the inner cavity of the product and reuse the core rod repeatedly.

[0003] In the core rod removal operation, mechanical grippers are mostly used for contact-type removal and placement of the core rod. This method is prone to cause scratches, wear and even breakage of the core rod during operation, affecting the service life of the core rod and product quality. Utility Model Content

[0004] The utility model aims to provide a core rod mechanism for loading and unloading equipment of a knurling machine, so as to solve the problems raised by the above-mentioned background technology.

[0019] Preferably, a gasket is installed on the surface of the inner cavity of the card block.

[0020] Preferably, support columns are installed at the four corners of the bottom end of the base.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The utility model adopts the electromagnetic sucker to take out the core rod, which effectively reduces the physical damage to the core rod during the operation and prolongs the service life of the core rod.

[0023] Since the electromagnetic chuck of the utility model can adjust the magnetic force, this design not only improves the flexibility of operation, but also can achieve optimal magnetic adsorption for core rods with different materials and surface characteristics, thereby minimizing damage to the core rod while ensuring the stability of taking and placing.

[0024] The utility model uses a soft material pad at the contact point between the card block and the product. This design can effectively disperse the pressure, reduce direct contact damage to the product, and further protect the product surface to avoid scratches or wear.

[0025] The utility model provides an electromagnetic sucker for core rod removal, thereby improving the efficiency and safety of core rod removal operation, reducing the difficulty of operation, saving labor costs, and also reducing damage to the core rod, extending the service life of the core rod, and reducing production costs.

[0040] By setting the clamping block 201, when the product is placed into the unloading mechanism 102 by the transplanting mechanism 103, the first cylinder 2 is started, and the output rod of the first cylinder 2 drives the clamping block 201 to move, and the product can be clamped through the rectangular groove 5 to prevent the product from moving when the core rod is removed.
