Description

Technical Field

[0001] The utility model relates to the technical field of pipe structure and processing thereof, in particular to an extrusion part structure of large-caliber thick-wall high-efficiency pipe processing equipment. Background Art

[0002] In the hydrometallurgical process, a dissolution reactor is usually used to achieve heat exchange between ore raw materials and steam, aqueous solution or other liquids. The heat exchange tubes in the dissolution reactor serve as heat exchange channels for ore raw materials (e.g., metallurgical slurry). In order to reduce the scaling of metallurgical slurry in the heat exchange tubes, it is usually necessary to make the metallurgical slurry have a higher flow rate, which aggravates the scouring and wear of the inside of the heat exchange tubes, resulting in a reduction in service life; and in order to ensure that the heat exchange time is long enough, the size of the heat exchange tubes needs to be designed to be longer, and the overall equipment size needs to be larger.

[0003] Therefore, the applicant has designed a large-diameter, thick-walled, high-efficiency pipe to solve the above technical problems. At the same time, the applicant has also designed a large-diameter, thick-walled, high-efficiency pipe processing equipment, including an extrusion part structure and a rotary feeding part structure. However, how the extrusion part structure should be designed to have a simpler and more reasonable structural design, better complete the processing, and more uniform force on the workpiece during the processing has become a further technical problem to be solved.

[0010] In this way, the driving cylinder is used for driving, the operation is more reliable, and the layout is also more convenient.

[0011] Furthermore, the front end of the extrusion head is designed to be a hemispherical structure.

[0012] In this way, the structural design of the extrusion head is simpler and more reasonable.

[0013] Furthermore, the mounting frame includes two frame plates arranged vertically and spaced apart along the longitudinal direction of the frame, a through hole is respectively provided at the center position of the two frame plates, and the two through holes together form the workpiece passage opening; the mounting plate is provided between the two frame plates, and the longitudinal ends of the mounting plate are respectively connected and fixed to the inner side surfaces of the frame plates.

[0014] In this way, the structural design of the mounting frame is simpler, the overall structure is more stable, and the mounting plate can be more conveniently arranged.

[0015] Furthermore, reinforcing rib plates are respectively arranged on both lateral sides of the outer surface of the mounting plate, and both ends of the reinforcing rib plates are respectively connected and fixed to the inner side surface of the frame plate.

[0016] In this way, stability can be improved by designing a reinforcing rib plate.

[0017] Furthermore, a stabilizing rib plate is respectively arranged between the two ends of the two reinforcing rib plates, and the lower side and the outer side of the stabilizing rib plate are respectively connected and fixed to the mounting plate and the frame plate.

[0018] In this way, by providing the stabilizing ribs, the structural strength of the mounting frame can be improved.

[0019] Furthermore, the mounting frame also includes a horizontally arranged mounting support plate at the lower end; and the lower end of the frame body plate is connected and fixed to the mounting support plate; and fixed rib plates are arranged in pairs between one of the frame body plates and the mounting support plate.

[0020] In this way, by providing a mounting support plate and arranging the mounting frame on the mounting support plate, installation and fixing can be more convenient.

[0021] Furthermore, the rack includes a support frame at one end, and the mounting support plate is fixed to the support frame by fixing screws.

[0022] In this way, the structural design of the rack is simpler, and the separately designed support frame can more conveniently adjust the longitudinal distance size.

[0023] Furthermore, a supporting cylinder arranged vertically upward is installed on the inner surface of one of the frame plates and through an installation support block, an arc-shaped supporting plate is connected to the working end of the supporting cylinder, and the supporting cylinder can drive the arc-shaped supporting plate to move upward and support it on the lower side of the workpiece in the workpiece passage opening.

[0024] In this way, by providing the supporting cylinder box arc-shaped supporting block, the workpiece can be supported, and the sagging of one end of the workpiece can be better prevented, thereby better ensuring the processing quality. BRIEF DESCRIPTION OF THE DRAWINGS
