Abstract
The invention discloses a fan frame with a casting not provided with locking lugs. The fan frame comprises a die casting upper cover and a punching base body. The casting upper cover is fixedly connected with the punching base body to form the fan frame; and the punching base body is provided with a connecting structure fixedly connected with a computer. According to the fan frame with the casting not provided with locking lugs, due to the fact that the connecting structure connected with the computer is arranged on the high-strength punching base body, the structure of the die casting upper cover is simplified, molding of the die casting is facilitated, subsequent machining and testing processes are simplified, cost is reduced, the finished product rate of products is increased, and subsequent use stability is improved.
Description
Technical field
The present invention relates to a kind of computer cooling fan, particularly a kind of foundry goods is without the fan frame of lock ear.
Background technique
Radiation fan on computer comprises the die casting upper cover of die casting, by the punching press matrix of metallic plate punching, flabellum and fan axle etc., wherein die casting upper cover and punching press matrix are fixedly connected to form the framework of whole fan, the current fan structure of installing on computers covers to arrange lock ear and realize in die casting, die casting cover except there being lock ear, the closure structure be combined with punching press matrix phase in addition (includes but not limited to lock tooth hole, riveted riveting post etc.), but this structure easily causes certain difficulty to die cast, because ear is thin little, shaping easy defectiveness: slight crack, the problems such as Sha Kong, intensity not easily reaches, and lock ear shaping rear workshop section complex procedures cost is high: infer test because doing, resist and fall test, CNC processing etc., said structure causes die casting upper cover molding rate low, and rate of good product is low, following process and detection complex procedures, cost of production remains high, and product later stage stability in use is poor.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides the fan frame of a kind of foundry goods without lock ear, this foundry goods is easy to manufacturing without the fan frame of lock ear, and rate of good product is high, and cost of production is low, uses stable.
The present invention in order to the technological scheme solving its technical problem and adopt is: a kind of foundry goods is without the fan frame of lock ear, comprise die casting upper cover and punching press matrix, described die casting upper cover and punching press matrix are fixedly connected to form fan frame, and described punching press matrix is provided with the linkage structure be fixedly connected with computer.
As a further improvement on the present invention, the linkage structure that described punching press matrix is fixedly connected with computer is at least three lock ear structures being located at punching press matrix border, and each lock ear structure is provided with the perforation worn for link.
As a further improvement on the present invention, on the lock ear structure of described punching press matrix, perforation is elongate holes.
As a further improvement on the present invention, described each lock ear structure is uniformly distributed on punching press matrix border.
As a further improvement on the present invention, described punching press matrix is fixedly connected with by stud or rivet with die casting upper cover.
The invention has the beneficial effects as follows: the present invention is by being arranged on the high punching press matrix of intensity by the linkage structure be connected with computer, simplify die casting superstructure, be convenient to the shaping of die castings, simplify following process and test step, save cost, improve finished product rate and follow-up stability in use.

Fig. 2 is die casting upper cover plan view;
Fig. 3 is punching press matrix plan view;
Fig. 4 is structural principle plan view of the present invention.
Embodiment
Embodiment: a kind of foundry goods, without the fan frame of lock ear, comprises die casting upper cover 1 and punching press matrix 2, described die casting upper cover 1 is fixedly connected to form fan frame with punching press matrix 2, and described punching press matrix 2 is provided with the linkage structure be fixedly connected with computer.The linkage structure be fixedly connected with computer is designed in punch pad, intensity is guaranteed, and processing is more reasonable, the processing of stamping part is simpler and easy, avoid and design linkage structure on die casting upper cover 1, be convenient to the shaping of die castings, simplify following process and test step, save cost, improve finished product rate and follow-up stability in use.
The linkage structure that described punching press matrix 2 is fixedly connected with computer is at least three lock ear structures 3 being located at punching press matrix 2 edge, each lock ear structure 3 is provided with the perforation 4 worn for link, link is connected with computer by the perforation 4 of lock ear, and then realize by fan fixed installation on computers, this structure is simple, be convenient to shaping, portion affects fan internal structure.
On the lock ear structure 3 of described punching press matrix 2, perforation 4 is elongate holes, can avoid because machining error causes the situation being difficult to be connected with computer.
Described each lock ear structure 3 is uniformly distributed on punching press matrix 2 edge, uniform force, stable connection.
Described punching press matrix 2 is fixedly connected with by stud or rivet with die casting upper cover 1, realizes die casting upper cover 1 sealed with punching press matrix 2.
