Auxiliary forced opening component of billet clamping device

Abstract

This invention relates to an auxiliary forced opening component for a billet clamping device. The billet clamping device has two clamping feet and an upper and lower crossbeam, spaced apart and connected to the clamping feet. Two chains are suspended from the bottom of the upper crossbeam. The auxiliary forced opening component includes two hook fasteners spaced apart on the lower crossbeam and corresponding to the two chains. Each hook fastener has a connecting plate and a fastening portion and an mounting portion on both sides of the connecting plate. The mounting portion is located on the lower crossbeam. One side of the fastening portion forms a mating opening, and the top forms a guide surface above the mating opening and corresponding to one of its chains. When the two chains move downwards and abut against the guide surfaces of the two hook fasteners, they can move along the guide surfaces towards the opening of the mating opening and automatically engage with it.

Claims

1. An auxiliary forced opening component for a billet clamping device, which is disposed in a billet clamping device having two clamping feet and an upper crossbeam and a lower crossbeam spaced apart and connected to the two clamping feet. A hydraulic control system is provided between the upper and lower crossbeams, and two chains are suspended from the bottom of the upper crossbeam. The auxiliary forced opening component of the billet clamping device comprises: two hook fasteners, which are spaced apart from each other on the lower crossbeam and correspond to the two chains. Each hook fastener has a connecting plate, a mounting part, and a fastening part. The mounting part is disposed at the bottom of the connecting plate and can be assembled on the lower crossbeam. The fastening part is disposed at the top of the connecting plate and has a mating opening and a guiding surface. The mating opening is formed on one side of the fastening part, and the guiding surface is formed on the top of the fastening part and located above the mating opening, corresponding to one of the chains. The upper crossbeam can be controlled to move towards the lower crossbeam, so that the two chains can respectively abut against the guide surfaces of the two hook fasteners and move along the guide surfaces toward the opening side of the mating opening of the two hook fasteners, and automatically engage with the mating opening.

2. The auxiliary forced opening component of the billet clamping device as described in claim 1, wherein, The guide surface of each hook and fastener extends downward at an angle toward the opening of the mating opening, and the top and bottom surfaces of the mating opening are parallel to the guide surface.

3. The auxiliary forced opening component of the billet clamping device as described in claim 1 or 2, wherein, The auxiliary forced opening component of the billet clamping device includes two bases, which are respectively disposed on the lower crossbeam and located below the two chains. The two hook fasteners are respectively detachably disposed on the two bases.

4. The auxiliary forced opening component of the billet clamping device as described in claim 3, wherein, Each of the hook fasteners has an mounting hole, and each of the bases has a connecting hole. The auxiliary forced opening component of the billet clamp device includes two pins, which are detachably inserted into the mounting holes of the two hook fasteners and the connecting holes of the two bases.

5. The auxiliary forced opening component of the billet clamping device as described in claim 3, wherein, Each of the hooks includes two positioning blocks, which are disposed on opposite sides of the connecting plate and extend downward, and can abut against the base at the corresponding position.

6. The auxiliary forced opening component of the billet clamping device as described in claim 4, wherein, Each of the hooks includes two positioning blocks, which are disposed on opposite sides of the connecting plate and extend downward, and can abut against the base at the corresponding position.
