Abstract
The invention discloses a manufacturing process of a dredging bucket. The manufacturing process comprises the following steps: 1) discharging: respectively discharging a bucket base plate and a bucket base plate reinforcing plate; 2) combination: connecting and combining the bucket base plate and the bucket base plate reinforcing plate through spot welding; 3) molding: molding the combined whole body by edge rolling through a hydraulic machine; 4) integrated splicing: splicing the molded bucket base plate and bucket base plate reinforcing plate and other parts into a bucket finished product. According to the process, an edge rolling scrap L= 150mm lengthened at the A-end does not need to be reserved, the process can be completed by one-time edge rolling, accordingly, the material utilization rate and the operating efficiency of the bucket during integrated splicing are improved, and the original four working procedures that the bucket base plate and the bucket base reinforcing plate are respectively edge-rolled are changed into one working procedure; the process is completed by the same working procedure, so that the contact surface of the bucket base plate and the bucket base plate reinforcing plate is in good contact, and the application prospect is broad.
Description
Technical field
The present invention relates to bucket machined and manufacture field, be specifically related to a kind of manufacturing process of bucket mechanical shovel bucket.
Background technology
Bottom sheet and the usual technique of bottom sheet stiffener of tradition bucket mechanical shovel bucket adopt gas cutting machine in steel plate loading and unloading, and hold at the A of bottom sheet and bottom sheet stiffener volume circle scrap (bridge) (as shown in Figure 1) lengthening L=150mm, after volume circle, 150mm scrap (bridge) is prescinded, as 43C1758 scraper bowl, each bottom sheet just has more the waste material of one piece of 150 × 999mm, the waste material of one piece of 150 × 310mm is had more (as shown in Figure 1 and Figure 2 at each bottom sheet stiffener, bottom sheet stiffener 3 pieces/platform), altogether create the waste leftover material of 11.2%; After each plate prescinds waste material, forward scraper bowl to always to spell, during total spelling, because each plate rolls up circle respectively, circle rolled up altogether by every platform scraper bowl just can complete one four times, and gradation volume circle makes the radian slightly difference of each plate of the volume of scraper bowl bottom sheet and bottom sheet stiffener circle, therefore, make bottom sheet contact well with bottom sheet stiffener contact surface, quite difficulty, shown in Fig. 1, " d=25mm " size also not easily ensures.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of manufacturing process of bucket mechanical shovel bucket, this manufacturing process lengthens the volume circle scrap (bridge) of L=150mm without the need to reserved A end, only once need roll up that circle is shaping just can be completed, and improves operating efficiency when stock utilization and scraper bowl are always spelled.
Object of the present invention carrys out specific implementation by the following technical programs:
A manufacturing process for bucket mechanical shovel bucket, comprises the following steps:
1) blanking: respectively to bottom sheet and the blanking of bottom sheet stiffener of scraper bowl;
2) component: bottom sheet is connected component with bottom sheet stiffener by spot welding;
3) shaping: the entirety after component is shaping by hydraulic press volume circle;
4) always spell: the bottom sheet after shaping and bottom sheet stiffener and miscellaneous part split are made scraper bowl finished product.
Further, 2), in step, when spot welding connects component, spot welding position strengthens the both sides of plate hole at bottom sheet, and make component when shaping, steel plate extends to both sides, can not cause dislocation position, hole.
The manufacturing process of a kind of bucket mechanical shovel of the present invention bucket, adopt blanking-component-shaping-total spelling can manufacture place's scraper bowl finished product, this technique is adopted to lengthen the volume circle scrap (bridge) of L=150mm without the need to reserved A end, only once need roll up that circle is shaping just can be completed, improve operating efficiency when stock utilization and scraper bowl are always spelled, by technological innovation, original bottom sheet and bottom sheet stiffener are rolled up four round procedures respectively, be embodied as a procedure and complete; Because same procedure completes, make bottom sheet contact well with bottom sheet stiffener contact surface, shown in Fig. 1, " d=25mm " size also can ensure, has broad application prospects.

Detailed description of the invention
As shown in Figure 3, Figure 4, the manufacturing process of a kind of bucket mechanical shovel bucket described in the embodiment of the present invention, comprises the following steps:
1) blanking: respectively to bottom sheet and the blanking of bottom sheet stiffener of scraper bowl;
2) component: bottom sheet is connected component with bottom sheet stiffener by spot welding, when spot welding connects component, spot welding position strengthens the both sides of plate hole at bottom sheet, see Fig. 4 dotted line place, dotted line place is each spot welding position place straight line, spot welding line length 15mm, consecutive points bonding wire interval 200mm, make component when shaping, steel plate extends to both sides, can not cause dislocation position, hole;
3) shaping: the entirety after component is shaping by 1000 t hydraulic press volume circles;
4) always spell: the bottom sheet after shaping and bottom sheet stiffener and miscellaneous part split are made scraper bowl finished product.
As shown in Figure 1 and Figure 2, the technological process adopting the structure shown in flow manufacturing diagram of traditional handicraft scraper bowl manufacturing process to adopt is:
1, bottom sheet (totally 1): blanking-volume circle-cut node head-turn total to spell;
2, bottom sheet stiffener (totally 3, make example for): blanking-volume circle-cut node head-turn total to spell.
Above-mentioned traditional handicraft adopts gas cutting machine in steel plate loading and unloading, and hold at the A of bottom sheet and bottom sheet stiffener the volume circle scrap (bridge) lengthening 150mm, after volume circle, 150mm scrap (bridge) is prescinded, after each plate prescinds waste material, forward scraper bowl to and always spell, during total spelling, because each plate rolls up circle respectively, the radian slightly difference of each plate, therefore, bottom sheet is made to contact well with bottom sheet stiffener contact surface, quite difficulty.
Adopt technique of the present invention: blanking (bottom sheet, three bottom sheet stiffeners)-component-shaping-total spelling can manufacture place's scraper bowl finished product, this technique is adopted to be directly roll up round shaping to entirety by 1000 t hydraulic press, the volume circle scrap (bridge) of L=150mm is lengthened without the need to reserved A end, only once need roll up that circle is shaping just can be completed, improve operating efficiency when stock utilization and scraper bowl are always spelled, pass through technological innovation, original bottom sheet and bottom sheet stiffener are rolled up 4 round procedures respectively, is embodied as one volume sired results sequence and completes; Because same procedure completes, make bottom sheet contact well with bottom sheet stiffener contact surface, shown in Fig. 1, " d=25mm " size also can ensure, has broad application prospects.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; it still can regulate the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
