Abstract
The invention relates to the technical field of vehicle manufacturing, and provides an integrated frame and a manufacturing method thereof. The frame is directly formed by casting, so that the strength and the rigidity of the frame are improved to ensure safety.
Description
Technical Field
The invention belongs to the technical field of vehicle manufacturing, and particularly relates to an integrated frame and a manufacturing method thereof.
Background
The motorcycle frame is one of the core components of a motorcycle, supporting the weight of the body, rider and all cargo, and assumes important safety functions. At present, the motorcycle frame structure is very complicated, a space three-dimensional structure is formed by welding a plurality of metal single parts, and a plurality of functional lugs and metal plates are welded according to the actual installation requirement. Motorcycle frames are almost formed by welding, in addition, in order to meet welding requirements, the welding fixtures are integrated on one fixture plate, a large number of tool fixtures are needed, the production and maintenance cost is increased due to the fact that the large number of tool fixtures are manufactured, welding cracks are easily generated due to changes of welding personnel, equipment, processes, materials and environments due to the adoption of the welding process, the service life is shortened, and dangerous factors are increased.
In the actual production process, the welding process cannot ensure sufficient strength and rigidity. Therefore, the traditional welding process is changed, and a novel frame manufacturing method and a frame are provided.
Disclosure of Invention
In view of the above-mentioned drawbacks, an object of the present invention is to provide a new frame manufacturing method and a new frame, and an integrated frame includes an integrated rear frame including a rear fork including a left leg arm and a right leg arm, which are integrated.
The integrated frame is a motorcycle frame.
The invention also discloses a manufacturing method of the integrated frame, which comprises the following steps:
s1: introducing compressed air into a sealed container filled with casting liquid, acting on a casting liquid surface maintaining a set pouring temperature, and enabling the sealed container to be in a first pressure state;
s2: injecting a casting liquid into the casting mold cavity through the sealed container in a first pressure state, and changing the air pressure of the sealed container to a second pressure state after the casting liquid is filled in the casting mold cavity;
s3: crystallizing, solidifying and forming the casting liquid.
Preferably, the method comprises the following steps:
after completion of S2 and before beginning of S3, the pressure value of the closed container is changed after the mold cavity is maintained for a rated time, the mold cavity communicated with the closed container is in a third pressure state, and the casting liquid is crystallized and molded under the state of the third pressure value.
Preferably, the third pressure value is greater than the second pressure value and the first pressure value.
The invention directly adopts integral casting molding, and improves the strength and rigidity of the frame to ensure safety. Therefore, the frame type of the bicycle can adapt to various frame types with complex structures, the frame structure is compact, welding cracks are avoided, the weight of the frame is reduced, the strength is greatly improved, welding materials and labor resources are effectively saved, the production cost is reduced, the product appearance is attractive and elegant, and the process requirements of energy conservation and environmental protection are met.

The integrated frame is a motorcycle frame.
The invention also discloses a manufacturing method of the integrated frame, which comprises the following steps:
s1: introducing compressed air into a sealed container filled with casting liquid, acting on a casting liquid surface maintaining a set pouring temperature, and enabling the sealed container to be in a first pressure state;
s2: injecting a casting liquid into the casting mold cavity through the sealed container in a first pressure state, and changing the air pressure of the sealed container to a second pressure state after the casting liquid is filled in the casting mold cavity;
s3: crystallizing, solidifying and forming the casting liquid.
Preferably, the method comprises the following steps:
after completion of S2 and before beginning of S3, the pressure value of the closed container is changed after the mold cavity is maintained for a rated time, the mold cavity communicated with the closed container is in a third pressure state, and the casting liquid is crystallized and molded under the state of the third pressure value.
Preferably, the third pressure value is greater than the second pressure value and the first pressure value.
The invention directly adopts integral casting molding, and improves the strength and rigidity of the frame to ensure safety. Therefore, the frame type of the bicycle can adapt to various frame types with complex structures, the frame structure is compact, welding cracks are avoided, the weight of the frame is reduced, the strength is greatly improved, welding materials and labor resources are effectively saved, the production cost is reduced, the product appearance is attractive and elegant, and the process requirements of energy conservation and environmental protection are met.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
