Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
The manufacturing process of the drainer pull rod shell as shown in fig. 1 to 2 comprises the following steps:
and a material cutting procedure, namely cutting the blank with the corresponding length according to the volume of the product. Specifically, based on the volume of a pull rod shell of the drainer to be manufactured, a required blank is cut on a stainless steel material by utilizing staggered knife edges of an inner cutter and an outer cutter;
and a flattening procedure, namely pushing the blank into a flattening die cavity and flattening the cut end surface of the blank. Mechanically pushing the cut blank into a pre-assembled initial flattening die cavity, punching the cut blank in a high-hardness and high-precision die cavity at a high temperature and a high speed by a front punching rod, leveling the cut blank to form a lower water heater pull rod shell initial shape with the same design shape and size of the die cavity, and ejecting the flattened blank by utilizing the recoil force of the die back punching;
and a shaping procedure, namely pushing the blank into a shaping die cavity to extrude the blank with the shape corresponding to the shape of the shell of the lower water device pull rod. Different die cavities are generally divided into a die cavity with a bottom and a die cavity with a through hole according to different blank requirements, the angle and the shape of the bottom of the die cavity are also different, and the shaping of the peripheral shape of the die cavity is designed and manufactured according to the requirements of products. The bottom of the shaping die cavity of the lower drainer pull rod shell is a semi-through arc bottom, and after a blank with the shape corresponding to that of the lower drainer pull rod shell is extruded, the blank is ejected by a rear punch of the die and sent to the next link;
and a material distribution process, namely pushing the flattened or shaped blank into a material distribution die cavity, and performing material distribution treatment on each part of the blank. Specifically, a portion of the billet is rapidly extruded to the dimensions required to form the various portions of the tie rod shell under rapid impact extrusion of a front punch within a fixed shape of the die cavity. Due to the different shapes of various parts of the shell of the drainer pull rod, the required size and the extruded part of the billet are different. After the material distribution process, extruding the blank into the corresponding shape of each part of the shell of the pull rod of the drainer, and then ejecting the blank out of the rear punch of the die to enter the next step;
and a rod section forming procedure, wherein the divided blank is pushed into the rod section forming procedure, and the depth and the outer diameter of the die cavity are designed according to the length and the outer diameter of the drainer pull rod. The middle rod section of the lower drainer pull rod shell is provided with a step semi-surrounding support body with the required size and angle of the lower drainer pull rod shell being the outer diameter by the die cavity at the outer edge part of the die. The front half part is fixed by the die cavity, and the rear half part is pressed and collided by the front punch to form a fixed body and is fixed by the front punch. The front rod diameter and height are quickly punched, a part of the blank is extruded to the outer edge of the die cavity in the die cavity to form the nodal surface of each shape, and then the external shape and the size which are consistent with those of the lower drainer pull rod shell are formed, so that the standard lower drainer pull rod shell is formed.
It should be noted that, in the present invention, the material shape of the material cutting process can be used to cut off blanks of different shapes, such as a circle, a square, a triangle or an irregular shape, according to the different shapes required by the product.
In the present invention, the sequence of the flattening step, the material dividing step, the shaping step, and the bar section molding step is determined by the shape and the type of the downcomer tie rod casing. When the types or shapes of the manufactured drainer pull rod shells are different, the sequence of the processes can be adjusted correspondingly or the processes can be reused, for example, the manufacturing process of the first embodiment shown in fig. 1 adopts the following steps: a material cutting process, a shaping process, a material distributing process and a rod section forming process;
the manufacturing process of the second embodiment shown in fig. 2 adopts the following steps: the method comprises the following steps of material cutting, flattening, shaping, material distribution, rod section forming and rod section forming.
As mentioned above, the manufacturing process of the drainer pull rod shell adopts the forging manufacturing mode to form at one time, so that the manufacturing process of the drainer pull rod shell is simpler, the production cost of the pull rod shell is reduced, and the quality and the efficiency of the drainer pull rod are improved.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and those modifications and variations assumed in the above are also considered to be within the protective scope of the present invention.
