Problems solved by technology

However, during the production process, due to factors such as deformation and welding positioning, the welding convex part 100 at the end of the semi-finished fan blade is rotated and displaced, and cannot coincide with the welding concave part 200 at the end of another semi-finished fan blade, which affects the cross-flow fan. The welding accuracy of the finished welding part 300 leads to a low production pass rate of cross-flow fan blades, and also reduces production efficiency

[0052] see Figure 9-Figure 12 , the front mold core adjustment mechanism of the cross-flow fan blade is different from the first embodiment in that: the adjustment member is an adjustment gear 16, and one end is provided with an adjustment function part 21, and the periphery is provided with a tooth part 24; The side of the front mold core 7 is provided with a tooth fitting part 25, and the tooth fitting part 25 is engaged with the tooth part 24 for transmission.

[0053] The action part 21 is adjusted by a tool or manually, and the driving adjustment gear 16 is positioned and rotated on the front mold base 13. When the adjustment gear 16 is positioned and rotated, the front mold core 7 is driven to rotate by the engagement of the tooth portion 24 and the tooth matching portion 25. Between the front mold base 13 and the mold seat plate 14.

[0054] Specifically, the regulating action part 21 of the regulating gear 16 is designed as an inner hexagon, which is used to cooperat...

Abstract

The invention discloses a front mold core adjusting mechanism of a cross-flow fan blade. The mechanism includes a front mold core, a front mold blank, and a mold seat plate, the front mold blank is arranged on the mold seat plate, the front mold core is arranged between the front mold blank and the mold seat plate, and is provided with a mold chamber consistent with a fan blade semi-finished product welding concave part, an adjusting part is arranged on the front mold blank or the mold seat plate, the adjusting part rotates on the front mold blank or the mold seat plate in a positioning mode,and is connected with the front mold core in a driving mode when rotating in a positioning mode, and the front mold core rotates between the front mold blank and the mold seat plate through the driving of the adjusting part. According to the mechanism, through the improvement of the structure, so that the mold chamber on the front mold core can adjust an angle at any time according to the deformation of the cross-flow fan blade and the welding requirement, the produced welding concave part can be consistent with a welding protrusion in high precision, so that the welding precision of the cross-flow fan blade can be improved, the production cost can be lowered, and the production efficiency and qualified rate can be improved.

Description

technical field [0001] The invention relates to a front mold core adjustment mechanism of a cross-flow fan blade. Background technique [0002] The structure of the finished cross-flow fan blades on the market is as follows: Figure 14 As shown, it consists of several such as Figure 15 , Figure 16 The semi-finished fan blade is formed by superimposing the welding convex part 100 and the welding concave part 200 at the end, and then ultrasonic welding. However, during the production process, due to factors such as deformation and welding positioning, the welding convex part 100 at the end of the semi-finished fan blade is rotated and displaced, and cannot coincide with the welding concave part 200 at the end of another semi-finished fan blade, which affects the cross-flow fan. The welding accuracy of the finished welding part 300 leads to a low production pass rate of the cross-flow fan blade, and also reduces production efficiency. Therefore, further improvement is nece...
