Embodiment Construction

[0020] refer to figure 1 , figure 2 , the present invention is a kind of manufacturing process of tapered mud door, comprises the following steps:

[0021] 1) Assemble the tooling platform 1 with an inverted cone-shaped inner cavity, and set a number of conical surface templates 11 uniformly distributed at equal angles in the tooling platform 1. The inclination of each conical surface template 11 is equal to the inclination of the cone generatrix of the conical panel 2 degree, and complete the ground sample marking under the tooling platform 1, and determine the center of the flange pipe 3 and the flange 31;

[0022] 2), the tapered panel 2 is divided into several parts according to the circumference and equal angles for blanking and bending processing to form a number of tapered panel assemblies;

[0023] 3), each conical panel assembly is placed upside down in the tooling platform 1 for assembly, and a complete conical panel 2 is formed by welding after the assembly is co...

Abstract

The invention discloses a production process of a conical mud door. According to the production process of the conical mud door, an inverted conical tooling platform is arranged in an inner cavity, so that a conical panel can be positioned and fixed through the tooling platform in the production process of the conical mud door, the problem that an existing conical panel is separately fixed is solved, the production efficiency of the conical mud door can be effectively improved, and the production precision of the conical mud door can be preferably guaranteed. The production process of the conical mud door is used in the production field of dredge mud doors.

Description

technical field [0001] The invention relates to the field of assembling a mud door of a dredger, in particular to a manufacturing process of a tapered mud door. Background technique [0002] The main structural parts of the dredger conical mud door are composed of flange and cone. In the production process of the cone-shaped mud door, the following parameters need to be controlled mainly: including the perpendicularity between the flange end surface and the centerline of the cone; the perpendicularity between the bottom panel of the cone and the centerline of the cone; The flatness of the profile. [0003] Due to the special structure of the conical bottom plate, that is, the curved plate structure of the conical mud door, it is very difficult to control the positioning and precision during the production process of the conical mud door. Contents of the invention [0004] In order to solve the above problems, the present invention provides a manufacturing process of a ta...
