Description

Technical Field

[0001] The utility model belongs to the technical field of powder metallurgy parts shaping, in particular to a sealing rod roller shaping die. Background Art

[0002] The sealing rod is a one-piece component manufactured using powder metallurgy technology. From back to front, it consists of the rod end, the rod shaft, and the rod head. The rod head is disc-shaped, and the end face of the rod end is round, with the diameter of the rod end face smaller than that of the rod head. After sintering, this part will have some bending deformation, requiring reshaping to correct the coaxiality between the rod end, the rod shaft, and the rod head.

[0003] The shaping method in the prior art is to manually press and shape the two half-circle shaping blocks one at a time with a pneumatic press, which has the following disadvantages:

[0004] 1. Manual shaping is affected by the operator's proficiency and the shaping speed is low;

[0005] 2. Inconsistent rotation angles during manual shaping will result in a certain deviation in the size after shaping;

[0006] 3. Unable to connect to automated equipment and realize automated shaping;

[0007] 4. During shaping, the product rotation will cause friction with the shaping die, causing wear of the shaping die;

[0008] 5. During the shaping process, the shaping mold needs to be manually moved. If the pneumatic press is started abnormally, the operator's hand may be crushed, which poses a certain safety hazard.

[0009] Therefore, a sealing rod roller shaping die is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0049] Example 1

[0050] like Figures 1 to 7As shown, a sealing rod roller shaping mold is used to shape a sealing rod 1. The sealing rod is an integrated structure, and comprises, from back to front, a rod tail 2, a rod body 3, and a rod head 4. The rod head is disc-shaped, the rod tail is circular, and the diameter of the rod tail end face is smaller than the diameter of the rod head. The roller shaping mold includes two support baffles 5 symmetrically arranged front and back; a shaping component is provided between the support baffles.

[0051] The shaping assembly includes an outer hoop 6, a roller 7, and a central shaft 8;

[0052] The outer hoop is fixedly arranged between the two support baffles, and the roller is rotatably arranged at the center of the outer hoop through the central shaft; the central shaft is fixedly connected to the roller, and both ends of the central shaft pass through the corresponding support baffles and are rotatably connected to the support baffles through bearings 9;

[0053] The outer hoop is C-shaped, and the opening of the outer hoop is located on the upper left side; the inner ring profile of the outer hoop matches the sealing rod; and the outer ring profile of the roller matches the sealing rod.

[0054] The head portion 10 of the outer hoop is a plane, which is tilted and points to the upper right; the tail portion 11 of the outer hoop is an arc-shaped surface.

[0055] The roller shaping die further comprises a guide plate 12 ; the guide plate is arranged tilted to the lower right, pointing to the gap between the outer hoop head and the roller.

[0056] The roller shaping die further comprises a blanking plate 13, which is arranged on the outside of the tail of the outer hoop and tilted to the lower left.

[0057] The inner ring of the outer hoop has, from front to back, a rod head shaping groove A14, a rod body shaping protrusion A15, and a rod tail shaping groove A16;

[0058] The outer ring of the roller is provided with a rod head shaping groove B17, a rod body shaping protrusion B18, and a rod tail shaping groove B19 from front to back.

[0059] The spacing between the rod head shaping groove A and the rod head shaping groove B matches the rod head of the sealing rod; the spacing between the rod shaft shaping protrusion A and the rod shaft shaping protrusion B matches the rod shaft of the sealing rod; and the spacing between the rod tail shaping groove A and the rod tail shaping groove B matches the rod tail of the sealing rod. A shaping cavity is formed between the outer hoop and the roller.

[0060] Working principle:

[0061] When this embodiment is in use, the sealing rod enters the roller shaping mold from the gap between the head of the outer hoop and the roller, and the central shaft drives the roller to rotate clockwise. When the roller rotates, it drives the sealing rod to rotate counterclockwise, and then passes through the shaping cavity to complete the shaping and escape from the tail of the outer hoop. During the rotation and rolling process of the sealing rod in the shaping cavity, the coaxiality and size of the two ends and the middle part of the product will be shaped to the process requirements due to the limitations of the contouring structure of the roller and the outer hoop.

[0062] Furthermore, the sealing rod can be guided into the over-shaping cavity by a guide plate, and then guided out by a blanking plate after the shaping is completed.

[0063] The central axis of the utility model can be connected to a motor through existing technology, so that the shaping can be mechanized and automated.

[0064] When the motor is not in use, the central shaft can also be manually rotated to drive the roller to rotate. In order to facilitate the rotation of the central shaft, a corresponding handle can be installed on the central shaft.

[0065] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Any technical deformation made according to the technical solution of the present invention falls within the protection scope of the present invention.
