7results about "Forging hammers" patented technology

The present application relates to the field of aluminum forging forging manufacturing, particularly to a kind of aluminum forging forging press and forging method, including anvil and hammer seat, four corners of the anvil are all fixed with vertical slide rod, the upper end of vertical slide rod is fixed with hydraulic mechanism, the hammer seat is slid through four vertical slide rods and is fixedly connected with the lower end of hydraulic mechanism, the anvil upper end front and rear direction is equipped with semicircular groove, semicircular groove is matched with semicircular seat rotation.The present application includes S1, the plane of semicircular seat is in the same plane with the upper end surface of anvil;S2, aluminum alloy blank is placed in semicircular seat and the upper end surface of anvil, the hammer seat is controlled to slide down by hydraulic mechanism, and the forging of aluminum alloy blank is formed;S3, semicircular seat is controlled to rotate on anvil, the upper end surface of anvil and the plane of semicircular seat form height difference, and aluminum alloy blank is turned over using this height difference, then semicircular seat is rotated again, and forging is carried out again.The present application is convenient for turning over aluminum alloy blank during forging.

The utility model relates to electro -hydraulic hammer technical field discloses a kind of electro -hydraulic hammer with protective device, including installation base, fixed assembly and forging table are provided on the installation base, the outside of the forging table is provided with protective assembly, the side, away from the forging table of the protective assembly, is provided with detection assembly, the side of the fixed assembly is provided with control center;In the utility model, by the protective assembly is set in the position with a certain distance from forging table, avoid the metal scrap that flies out in the forging hammering process and rebound on forging table after hitting protective shell, lead to the forging effect is poor;By setting detection assembly, whether there is staff standing outside protective assembly is detected currently, control center receives signal, control protective assembly adjusts, block metal scrap and fly out, avoid splashing to the face of staff, lead to staff injury, ensure the safety of personnel.

A forming jaw of a rotary swaging tool for shaping a plastically deformable, preferably metallic, workpiece has a jaw main body and a forming body which is a separate component from the jaw main body and is mounted on the jaw main body, preferably connected to the jaw main body. On a side facing the workpiece, the forming body is bounded by a shaping surface designed for shaping a workpiece. A rotary swaging tool has at least one forming jaw of the above-mentioned type.

This invention relates to the field of forging equipment technology, and provides a forging device for manufacturing round magnesium alloy forgings. The device includes a forging machine body, on which a forging die is mounted. The forging die has a forging groove, and a receiving space is provided at the bottom of the forging groove within the forging machine body. An ejector mechanism is installed within this receiving space. This invention overcomes the shortcomings of existing technologies, featuring a reasonable design and compact structure. By using a horizontally movable pressure plate that cooperates with stepped bearing portions on both sides of the receiving space, it avoids long-term heavy loads or impacts on drive components such as screws and gears during ejection, significantly reducing wear and overload damage risks to the drive unit. Initially, the ejector pin is located at the bottom of the forging groove, and after the bottom of the billet is placed in, the exposed portion of its top is less than half of its total length. Manual clamping and support with pliers is required, reducing labor intensity and significantly improving operational safety.

The invention relates to an electric contact element (2) comprising a bent portion (46), the bent portion having a cross-section (10) with at least one corner (26). The invention also relates to a method for manufacturing such an electric contact, e.g. from sheet material by stamping and bending the electric contact element (2). Due to an increased miniaturization of such electric contact elements (2), it is increasingly difficult to ensure that the electric contact elements (2) keep pre-determined position tolerances after bending. It has been observed that the bending process gets more accurate when the corner (26) is chamfered at least in the bent portion (46).

This utility model relates to the field of bearing processing technology and discloses a bearing press for convenient positioning. The positioning assembly consists of a one-way threaded rod, a motor, a first bevel gear, a first slide rod, a first moving block, a first arc-shaped plate, a two-way threaded rod, a second bevel gear, a second slide rod, a second moving block, and a second arc-shaped plate. The one-way threaded rod is rotatably mounted inside the operating table, the motor is fixedly mounted on the side of the operating table, the first bevel gear is fixedly mounted on the surface of the one-way threaded rod, and the first slide rod is fixedly mounted inside the operating table. This convenient bearing press, by starting the motor to rotate the one-way threaded rod, can drive the first arc-shaped plate to move. Under the action of the first and second bevel gears, the two-way threaded rod can be rotated, which can drive the second arc-shaped plate to move. Under the combined action of the first and second arc-shaped plates, the bearing can be positioned, resulting in good performance.
