Description

Technical Field

[0001] This utility model relates to the field of pipe forging technology, specifically a forging machine for producing high-pressure forgings. Background Technology

[0002] In the production of high-pressure forgings, especially in the processing of pipe forgings, precise forging of the pipes is required to ensure their strength, pressure resistance, and other properties. Traditional forging machines suffer from problems such as poor support and limiting of the pipes, inconvenient adjustment of the forging position, and poor compatibility with different pipe specifications, which affect the quality of forgings and production efficiency. Therefore, a forging machine that can be precisely adjusted, stably supported, and adapted to the forging of various pipe materials is needed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forging machine for producing high-pressure forgings, comprising a support mechanism, an adjustment mechanism, an intermediate forging auxiliary mechanism, and upper and lower forging mechanisms. The support mechanism provides basic support for the entire equipment and includes a frame plate with a strip groove. It also includes a support that mates with the frame plate and a base for overall equipment mounting and fixing, with mounting holes on the base. The adjustment mechanism is used to achieve position adjustment and includes a slidably mounted slide with a threaded hole. A column is fitted onto the slide, and a locking screw is inserted into the threaded hole to lock the slide's position. The intermediate forging auxiliary mechanism... The forging aid for the middle section of the pipe includes a fixing clip for placing the forming block of the middle section of the pipe to be forged. The fixing clip has a mating hole in which a fastening bolt is installed. The fixing clip can fix the forming block of the middle section of the pipe. The upper and lower forging mechanism is used to perform vertical forging operations on the pipe. It includes an external forging assembly, a connecting frame, and a hydraulic press that provides forging power. The hydraulic press is connected to a movable shaft. It also includes a fixing frame installed on the front side of the fixing frame plate. The adjusting mechanism is installed on the frame plate of the supporting mechanism. The intermediate forging auxiliary mechanism is adapted to the adjusting mechanism. The upper and lower forging mechanism is erected above the supporting mechanism. All mechanisms work together to complete the pipe forging operation.

[0007] As a further embodiment of this utility model: the frame plate of the support mechanism is a cuboid frame structure, the strip groove is opened along the length direction of the frame plate, and is used to provide sliding guidance and installation space for the slide of the adjustment mechanism. The bottom of the slide of the adjustment mechanism is adapted to the strip groove structure of the frame plate of the support mechanism and can slide along the strip groove. The column is vertically installed on the upper surface of the slide and is used to support and connect the intermediate forging auxiliary mechanism.

[0008] As a further embodiment of this utility model: the fixing clip of the intermediate forging auxiliary mechanism is a semi-circular arc structure. The two fixing clips cooperate to initially limit the position of the pipe. The upper surface of the forming block in the middle of the pipe is an arc-shaped surface adapted to the inner contour of the pipe.

[0009] As a further improvement of this utility model: the base of the support mechanism is a rectangular plate structure, and there are two mounting holes, which are respectively opened at the front and rear ends of the base, for use with bolts to fix the equipment in the work site. The locking screw of the adjustment mechanism is a hand-tightening bolt. After tightening, the end of the locking screw abuts against the side wall of the frame plate of the support mechanism to lock the position of the slide.

[0010] As a further improvement of this utility model: the fastening bolts of the intermediate forging auxiliary mechanism are hexagonal socket head cap screws, which are embedded in the mating hole to avoid interfering with the forging operation; the fixing frame of the upper and lower forging mechanisms is a portal frame structure, spanning the front end of the frame plate of the support mechanism, providing stable support for the front hydraulic press and the external forging assembly of the pipe.
