Abstract
The invention discloses a manufacture technology of a door-opening beam and aims to solve the problems of great whole processing difficulty and uninsured manufacture precision of a welded ultra-big door-opening beam. A vertical box-shaped member and a horizontal box-shaped member are respectively scribed and mechanically processed at a joint and then assembled into a whole, central belt lines of the members are aligned so that the quality of tolerance between the verticality and the parallelism reaches an IT6 class, and the two qualified members are combined and welded with reinforcing plates. The invention has the advantages of high processing precision, simple and practical method, and the like.
Description
Technical field
The invention belongs to large-sized structural parts machined field, be specifically related to a kind of manufacture technology of door-opening beam.
Background technology
The beam that opens the door is the important component of coke over machinery ram, it is used for finishing the work that coke pushing moves forward and backward fire door, its version vertical and horizontal two parts box beam of serving as reasons connects into a T type structure, the high 8200mm box beam of long 12000mm size 800mm * 600mm, do not vibrate for guaranteeing to move forward and backward steadily, it should have good rigidly and high accuracy.
Process the such structural member of the similar beam that opens the door at present, the technology that adopts is the whole processing of postwelding usually.The medium and small beam that opens the door of this manufacture method processing can guarantee precision; But just can not realize for the ultra-large type this process of beam of opening the door, also not guarantee the accuracy of manufacture.
Summary of the invention
The present invention seeks to provides a kind of manufacture technology of door-opening beam at open the door beam processing of ultra-large type.
The present invention be with vertical and level two box-type members in the junction separate machined, be assembled into one then, and increase connecting plate so that assemble in two member junctions.
Described separate machined promptly is line and machined.
Draw the side of member and the cross center stringcourse of faying face for vertical box-type member, with the cross center stringcourse of side and faying face is that benchmark is drawn the junction and engaged upper thread, guarantees to engage the center waist line parallel, vertical with the center stringcourse of faying face of upper thread and side; With cross center, side stringcourse is that benchmark is drawn each hole line; Cross center stringcourse with faying face is that benchmark is drawn each rail level line.
Draw the side of member and the cross center stringcourse of faying face for horizontal box-type member, with the cross center stringcourse of side and faying face is that benchmark is drawn the junction and engaged upper thread, guarantees to engage the center waist line parallel, vertical with the center stringcourse of faying face of upper thread and side; Cross center stringcourse with side and faying face is that benchmark is drawn each rail level, guarantees the center waist line parallel, vertical with the center stringcourse of faying face of each rail level and side.
For vertical box-type member machined, the cross center stringcourse of centering side and faying face, the boring and milling faying face guarantees the center waist line parallel, vertical with the center stringcourse of faying face of faying face and side; Each rail level of boring and milling guarantees that the center stringcourse with the side is vertical, and the center waist line parallel of faying face; Each hole of boring guarantees the center waist line parallel, vertical with the center stringcourse of faying face of each hole and side.
For horizontal box-type member machined, each rail level of boring and milling guarantees the center waist line parallel, vertical with the center stringcourse of faying face of each rail level and side.
Described assembling promptly is that vertical and level two box-type member strictnesses are assembled by cross center stringcourse centering separately, the center stringcourse that should guarantee two box-type members during assembling is perpendicular or parallel mutually, same position of related features grade has also been made regulation, requires the perpendicularity and the depth of parallelism grade of tolerance to reach IT6 level (micron order).
The present invention is owing to resolve into two less members with a large-scale beam that opens the door, and line is processed, and then is assembled into one, processes this difficult problem for solution large-sized structural parts postwelding new manufacturing process is provided; It has the machining accuracy height, advantages such as method simple and feasible.
Description of drawings
The present invention is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the assembly schematic diagram of beam two box-type members of opening the door;
Fig. 2 is the vertical box-type member schematic diagram of the beam that opens the door;
Fig. 3 is the horizontal box-type member schematic diagram of the beam that opens the door.
Specific embodiment
As shown in Figure 1, open the door being assembled into one of beam two box-type members.
As shown in Figure 2, the vertical box component 1:A. that rules draws member 1 center stringcourse 3,4; B. be that benchmark is drawn junction joint upper thread 5 with center stringcourse 3,4, it is parallel, vertical with center stringcourse 4 with center stringcourse 3 to guarantee to engage upper thread; C. be that benchmark is drawn each hole line 11, is that benchmark is drawn each rail level line 6 with center stringcourse 4 with center stringcourse 3 equally;
Process vertical box component 1:A. centering center stringcourse 3,4, boring and milling faying face 5 guarantees that faying face 5 is parallel, vertical with center stringcourse 4 with center stringcourse 3; B. each rail level 6 of boring and milling guarantees vertical, parallel with center stringcourse 4 with center stringcourse 3; C. each hole 11 of boring guarantees that each hole 11 is parallel, vertical with center stringcourse 4 with center stringcourse 3.
As shown in Figure 3, line horizontal box member 2:A. draws member 2 center stringcourses 7,8; B. be that the benchmark check off closes upper thread 9 with center stringcourse 7,8, guarantee vertical with center stringcourse 7,8 in conjunction with upper thread 9; C. be that benchmark is drawn each rail level 10 with center stringcourse 7,8 equally, guarantee that each rail level is parallel, vertical with center stringcourse 8 with center stringcourse 7.
Each rail level 10 of level of processing box component 2:A. boring and milling.
For guaranteeing the dimensional accuracy of assembling back integral structure component, it is perpendicular or parallel with cross center stringcourses separately relatively to require two box-type members to interconnect the faying face 5 at place, and requiring the perpendicularity and the depth of parallelism grade of tolerance to reach IT6 level (micron order), the assembling position grade of tolerance has also been done corresponding raising.
Assemble two members: align two member center stringcourses 3,4,7,8, make the center stringcourse 3 of member 1 vertical, make the center stringcourse 4 of member 1 concentric with center stringcourse 8 with center stringcourse 7; After qualified with two members the merging gusset of burn-oning.
