4 results about "Shape matching" patented technology

A tool system for brake forming having a punch or a die and at least one insert. In one embodiment, two inserts are removably attached to a die. The die has a defined shape running along a longitudinal axis. Each insert has a protrusion with a particular cross-sectional shape running along the same longitudinal axis. The die has two cavities, each cavity having a cross-sectional shape matching the cross-sectional shape of the protrusion of one of the inserts. In another embodiment, the die has two protrusions and each insert has a cavity for receipt of one of the protrusions of the die. When one of the protrusions is inserted into one of the cavities, the insert is removably fixed to the die. At least one surface of each insert corresponds to and combines with the defined shape of the die, forming a bending surface against which a sheet of metal is formed. After press braking, the sheet of metal is substantially conformed to the defined shape of the die. In another embodiment, an insert is removably attached to a punch such that the insert forms the entire surface of the punch system that contacts the sheet of metal to be shaped during press braking. The inserts are positioned such that they encounter most of the wear caused by the brake forming, whereas the punch and the die encounter only minimal wear. As a result, the inserts are inexpensively repaired or replaced when needed, but the punch and the die remain in good condition during extended use.

The invention discloses a secondary mixing device for dry-mixed mortar, which comprises a cylinder (1), a cover (2) and a mixing rod (4). The top of the side wall of the cylinder (1) is provided with a gap, the seal The cover (2) closes the upper opening of the cylinder (1), and the lower end of the cover (2) is connected with a positioning protrusion (3) corresponding to the position of the notch of the cylinder (1) and matching in size and shape. The positioning protrusion (3) ) into the gap of the cylinder (1). The central part of the cover (2) is provided with a circular perforation, the mixing rod (4) passes through the circular perforation of the cover (2), and the lower end of the mixing rod (4) is in contact with the inner bottom of the cylinder (1) touch. The invention can carry out secondary mixing on the dry-mixed mortar transferred by the transfer device to a specific construction position, which can prevent the dry-mixed mortar from partially solidifying, thereby avoiding the waste of resources and the potential safety hazard of discarding the solidified dry-mixed mortar during high-altitude operations.

The invention discloses an on-line login identity authentication method based on palm shape matching. The method comprises the following steps that when application for registration is carried out, palm shape information of an applicant is extracted, and the palm shape information and user name information of the applicant are sent to an identity authentication management center to be stored; when a login user logins on line, palm shape information of the login user is extracted, and user name information inputted by the login user and the palm shape information of the login user are sent together to the identity authentication management center; the palm shape information of the login user is matched with the palm shape information of the applicant by the identity authentication management center; when the information is matched, the login user enters an operation interface from a login interface; and when the information is not matched, the login user is prohibited to enter the operation interface. The on-line login identity authentication method based on the palm shape matching has the advantage that through the palm shape information matching, safety of online transaction is greatly improved.

A 3D processing device configured to attach a decorative film on a surface of a 3D glass, the 3D processing device includes a decorative film pre-deformation unit and a attachment unit. The decorative film pre-deformation unit includes an upper mould and a lower mould opposite to the upper mould, wherein the upper mould engages the lower mould to press the decorative film and cause the decorative film to have a shape matching a surface of the 3D glass. The attachment unit defines a sealing chamber, and includes a mould and a gas bag within the sealing chamber, wherein the mould is configured to support the 3D glass. The present disclosure further provides a method thereof.
