Problems solved by technology
Since the mold base is a rigid structure, it is easy to generate reaction force during stamping, which will cause cracks in the metal powder blank and cause damage to the compressed part blank, resulting in low cost.
[0003] At present, the metal powder stamping machines that can be provided in China all have the same problem, and none of them have the application of buffer and balance devices.

The invention provides an elastic deformation balancing mechanism for an adjustable mould. An upper mould frame supporting component is provided with a second upper punch and a first upper punch through a second upper punch supporting component and a first upper punch supporting component; a female die, a first lower punch and an elastic deformation compensation mechanism are arranged below the first lower punch; and the outer sides of a lower core rod and a supporting component of the first lower punch are provided with a second lower punch, a second lower punch limiting and supporting component, a first lower punch limiting and supporting component, a third lower punch, a third lower punch limiting and supporting component and a pedestal respectively. The periphery of a punch lever consisting of the first lower punch, the second lower punch and the third lower punch is provided with a cushion block A and a cushion block B through pre-tightening bolts and locking bolts; a disc spring is arranged and a compensating regulation and measurement station is reserved between the cushion blocks; and the cushion blocks are fastened by large adjusting nuts. The blanks of punched powdered metal parts have stable and consistent shape and size, and quality and production efficiency can be improved. The mechanism is suitable for machining the parts in a powdered metal metallurgy industry.
Description
technical field [0001] The invention proposes an adjustable mold elastic deformation balance mechanism for metal processing in the mechanical field. Background technique [0002] At present, for metal powder metallurgy to manufacture mechanical parts, the metal alloy powder is generally squeezed out in stages through punches of different heights to make it into a set shape. After the punch punches the metal powder in the cavity, the metal powder will be densely filled into the cavity to form a compressed part that is powdery and consistent with the cavity of the mold. Due to the rigid structure of the mold base, it is easy to generate reaction force during stamping, which will cause cracks in the metal powder blank, resulting in damage to the compressed part blank, resulting in low cost. [0003] At present, the metal powder stamping machines that can be provided in China all have the same problem, and there is no application of buffer and balancing devices. [0004] It is...
