Problems solved by technology

Especially for hinges with greater stress, the thickness of the top plate is thicker, which increases the weight of the hinge, which is not only economical, but also unfavorable for transportation
[0003]Usually, the hinges are processed by casting. Since the top plate of the existing hinge is relatively thick, and there are multiple reinforcing ribs on the top plate and the connecting hole plate, during the casting process Casting cracks, cold shuts or shrinkage defects due to poor flow of casting liquid affect the casting quality of hinges

Embodiment 1

[0028] This example figure 1 and figure 2 The one shown is a straight arm hinge, the connecting orifice plate 2 on the hinge is provided with a shaft hole 8 connected with the supporting shaft on the fixed hinge seat, the top of the connecting orifice plate 2 is a Y-shaped structure, and there are two radial ribs 4. The bottoms of the two radial ribs 4 are connected to the connecting hole plate 2, and the tops of the two radial ribs 4 are connected to the bottom of the horizontal top plate 1 near the edge. Positioning strips 10 are arranged on both sides of the top plate 1, and a group of fixing holes 9 connected with the gate arm are arranged on the top surface of the top plate 1. The positioning is carried out by the positioning strip 10, and it is connected with the gate through the fixing hole 9. Two radial ribs 4 form a triangle with the top plate 1, and three transverse ribs 5 are arranged in the triangle, one in the middle and one on each side. A set of reinforcing ...

Embodiment 2

[0030] This example image 3 and Figure 4 What is shown is an oblique arm hinge. In this example, the connecting orifice plate 2 on the hinge is provided with a shaft hole 8 connected to the supporting shaft on the fixed hinge seat. The top of the connecting orifice plate 2 is a Y-shaped structure with three radial ribs. Plate 4, the bottom of three radial ribs 4 is connected to the connecting hole plate 2, the top of the middle of the three radial ribs 4 is connected to the middle of the bottom of the top plate 1, and the top of the other two radial ribs 4 is connected to the bottom of the top plate near the edge of the top plate, The top plate 1 is arranged obliquely. Positioning strips 10 are arranged on both sides of the top plate 1, and a group of fixing holes 9 connected with the gate arm are arranged on the top surface of the top plate 1. The positioning is carried out by the positioning strip 10, and it is connected with the gate through the fixing hole 9. Three ra...

Abstract

The invention discloses a method for reducing the weight of an arc door hinge and improving casting quality and a hinge structure. The method is to set the top of the existing connecting orifice plate so that the thickness is much smaller than the radial rib plate of the connecting orifice plate. The thickness of the radial rib plate is 1 / 5 to 1 / 3 of the thickness of the lower part of the connecting orifice plate. Connection: Since the joint between the radial rib plate and the top plate is closer to the edge of the top plate, the deformation of the edge of the top plate can be effectively prevented, so the thickness of the top plate can also be reduced accordingly, thereby reducing the overall weight of the hinge. The invention effectively reduces the weight of the hinge, improves the fluidity of the casting liquid during casting, reduces the cracks, cold shut and shrinkage defects caused by casting, and helps to improve the casting quality. The deficiency of the prior art is well solved.

Description

technical field [0001] The invention relates to a method for reducing the weight of an arc door hinge and improving casting quality and a hinge structure, belonging to the technical field of hinge production in water conservancy and hydropower projects. Background technique [0002] In water conservancy and hydropower projects, the arc gate is connected with the support arm through the hinge, and the hinge is the key component to ensure the reliable and flexible rotation of the arc gate. The hinge mainly includes a top plate connected with the support arm and a connecting orifice plate hinged with the supporting shaft of the fixed hinge seat of the gate. The connecting orifice plate and the top plate are connected in a T shape. This makes the distance between the connecting orifice plate and the arm flange plate farther. In order to improve the strength of the hinge, on the one hand, the thickness of the top plate can be increased, and a reinforcing rib can be set between t...
