Description
Technical Field
The utility model relates to a pipe fitting height concave surface dashes and lacks forming die, especially a pipe fitting height concave surface once dashes and lacks forming die.
Background
The high-low concave surface part of the pipe fitting is shown in figures 1 and 2, a punching concave high surface A and a punching concave low surface B in the high-low concave surface part of the pipe fitting need to adopt a one-time punching and notching technology, the traditional processing mode is that the pipe fitting is placed into a die cavity and then is notched for three times to obtain a shape, the side surface notching is carried out firstly, and then the high-low concave die is notched for two times, so that the production efficiency is low. Therefore, a one-step punching forming die for the high and low concave surfaces of the pipe fitting needs to be designed.
Disclosure of Invention
To the above-mentioned current phenomenon, the utility model provides a pipe fitting height concave surface once dashes and lacks forming die, dashes to lack original cubic and becomes once dashing to lack, has solved the part and has dashed the machining efficiency who lacks.
In order to achieve the above purpose, the technical scheme of the utility model is that: a pipe fitting high-low concave surface one-time punching forming die comprises a female die, a male die, a core rod and a cutter, wherein an arc cutting area used for wrapping pipe fitting high-low concave surface parts is arranged in the female die, a convex surface spliced with the female die is arranged at the front part of the male die, a through hole used for the cutter to penetrate into is also arranged in the male die, the shape of the core rod is matched with the inner shape of the pipe fitting high-low concave surface parts, and a punching concave notch of the high-low concave surface parts is arranged; the front end part of the cutter is provided with two material guide inclined planes and two 90-degree right-angle notch planes.
Further, the cutter is formed by combining two petals.
Further, the right-angle notch surface at the lower end of the material guide inclined surface is a punched concave high-surface cut surface, and the right-angle notch surface on the front end surface of the lower part of the cutter is a punched concave low-surface cut surface.
Further, during processing, the high-low concave part of the pipe fitting is placed in the core rod and then penetrates into the female die, the convex surface of the male die is spliced with the female die, and the cutter cuts the high-low concave part of the pipe fitting after penetrating through the through hole in the male die.
The utility model has the advantages that:
the utility model discloses dash and lack former cubic and become once to dash and lack, very big improvement the machining efficiency that the part dashes and lacks.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in fig. 3 and 4, the utility model discloses a high concave surface of pipe fitting once dashes and lacks forming die, including die 1, terrace die 2, cutter 3, plug 4. The die 1 is internally provided with an arc cutting area for wrapping the pipe fitting high-low concave part 5, the front part of the male die 2 is provided with a convex surface spliced with the die, the male die 2 is also internally provided with a through hole for a cutter to penetrate, the outer shape of the core rod 4 is matched with the inner shape of the pipe fitting high-low concave part, and the male die is provided with a concave punching notch of the high-low concave part. As shown in fig. 5 and 6, the cutter 3 is formed by combining two petals. The front end part of the cutter 3 is provided with two guide slopes 3-1 and two 90-degree right-angle notch surfaces, wherein the right-angle notch surface positioned at the lower end of the guide slope 3-1 is a punched concave high-surface cut surface 3-2, and the right-angle notch surface positioned on the front end surface of the lower part of the cutter is a punched concave low-surface cut surface 3-3.
The working principle is as follows: the pipe fitting high-low concave surface part 5 is placed into the core rod 4, then the pipe fitting high-low concave surface part 5 with the core rod 4 penetrates into the female die 1, the convex surface of the male die 2 moves to the left horizontally and is spliced with the female die 1, and the cutter 3 moves to the left horizontally to cut the pipe fitting high-low concave surface part 5. When the pipe fitting is retracted, the cutter 3 horizontally retracts first, the male die 2 horizontally moves to the right, and the pipe fitting high-low concave surface part 5 is taken out.
The core rod 4 is discharged by punching the concave low surface B, and discharged by punching the concave high surface A through the concave die 1.
