Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in FIG. 1, the blank of the filter housing comprises a circular cylinder 1 with one open end, and the wall thickness of the circular cylinder 1 is equal to ensure that the subsequent processing is convenient.
The other end of the round tube 1 is provided with a sealing part 2, the thickness of the sealing part 2 is larger than the wall thickness of the round tube 1, and the radial structural strength of the round tube 1 far away from the open end can be improved by the different designs of the sealing part 2 and the thickness, so that the reliability of the filter structure is ensured.
The inner end surface of the closed part 2 is vertical to the axis of the round tube 1. Secondly, the outer end face of the sealing part 2 inclines towards the hexagonal column 4 side, and the outer end face of the sealing part 2 forms an included angle smaller than 90 degrees with the axis of the circular cylinder 1.
An inner chamfer 10 is forged and formed at the inner side of the open end of the round barrel 1, and the inner chamfer 10 is an inclined chamfer. The inclined surface of the inclined chamfer extends to the half position of the end surface of the open end so as to ensure the structural strength of the open end after forging.
The connecting part of the inner wall of the circular cylinder 1 and the sealing part 2 is connected with an inner convex reinforcing part 3, specifically, the inner wall of the inner convex reinforcing part 3 is provided with an inclined slope surface 30 and an arc concave surface 31 which are sequentially connected and distributed from the opening of the circular cylinder 1 to the sealing part 2, the inclined slope surface 30 is connected with the circular cylinder 1 through an arc transition concave surface one 32, and the arc concave surface 31 is connected with the inner end surface of the sealing part 2 through an arc transition concave surface two 33.
The radial structure can be reinforced by the inward convex reinforcing part 3 and the closed part 2 in cooperation, so that the deformation resistance is improved.
As shown in fig. 1 and 2, a hexagonal prism 4 is provided in the center of one end surface of the closing portion 2 away from the circular tube 1 and the axis of the hexagonal prism 4 coincides with the axis of the circular tube 1. After finally punching through sealing part 2 and hexagonal post 4, the tooth then can be attacked to hexagonal post 4 inside this moment, just also can realize being connected with the screw rod, through forging hexagonal post 4 in advance it can omit the welding in later stage to and the location when hexagonal post 4 can be used for punching, can improve the meshing degree of attacking tooth screw and screw rod and being connected.
The hexagonal column 4 is simple in forging and forming and stable in size, and positioning can be achieved as long as the hexagonal hole is designed on the drilling tool for the insertion of the hexagonal column 4.
As shown in fig. 1 and 3, an annular avoidance step 40 is provided at an end of the hexagonal cylinder 4 remote from the closing part 2, and specifically, the annular avoidance step 40 includes an annular inclined surface 400 provided on an upper side of a lower end face of the hexagonal cylinder 4, and a cylindrical surface 401 connected to the annular inclined surface 400. Step 40 is dodged to the annular can prevent that contact of mutual casing in the transportation from resulting in the hexagonal column to gouge, influences the subsequent smoothness of inserting in the hexagonal hole.
