Problems solved by technology

[0002] The processing of the rough bottle is generally divided into two methods: blow blowing and pressure blowing. The pressure blowing method is to press the bottle through the stamping assembly once, and blow it again to form the rough bottle; the existing stamping assembly is made of The die, the mouth ring and the punch are composed of three parts, but the existing stamping assembly will cause many problems due to the unreasonable structural design, which will affect the processing quality of the bottle
[0003] For example, the stroke of the existing punch is too long, which not only increases the pressure of the punch, but also is not conducive to controlling the weight of the product

Embodiment

[0012] Embodiment: A stamping assembly that can reduce stamping pressure, such as figure 1 As shown, it includes the die 1, the mouth ring 2 and the punch 3, and the first through hole 4 and the second through hole 5 for the punch to move in and out are respectively provided in the die 1 and the mouth ring 2, and the mouth ring 2 is set In die 1. The punch 3 is sleeved in the first through hole 4 and the second through hole 5, and the head of the punch 3 is exposed outside the die 1. The convex ring 30 at the lower part of the punch 3 is against the mouth ring 2, and the convex ring 30 is the mouth Stopped by the ring 2, the distance d1 between the bottom end of the mouth ring 2 and the bottom end of the die 1 is 1.0 cm.

[0013] At the punch entrance 11 at the bottom of the die, the inner diameter of the first through hole 4 changes from large to small; at the punch entrance 12 at the bottom of the mouth ring, the inner diameter of the second through hole 5 changes from larg...

Abstract

The invention discloses a stamping assembly capable of reducing stamping pressure. The stamping assembly comprises a die, a port ring and a punch, a first through hole and a second through hole for the punch to pass in and out and move are respectively arranged in the die and the port ring, the port ring is arranged in the die, the punch is sheathed in the first through hole and the second through hole, the head of the punch is exposed out of the die, a convex ring at the lower part of the punch is supported against the port ring, and the distance between the bottom end of the port ring and the bottom end of the die ranges from 0.8-1.1cm. According to the stamping assembly, the distance between the bottom end of the die and the bottom end of the port ring can be adjusted, and the stroke of the punch can be shortened, thereby being capable of reducing the pressure on the punch, and being beneficial to control on the weight of products.

Description

technical field [0001] The invention relates to a rough processing accessory for a bottle, in particular to a stamping assembly capable of reducing stamping pressure. Background technique [0002] The processing of the rough bottle is generally divided into two methods: blow blowing and pressure blowing. The pressure blowing method is to press the bottle through the stamping assembly once, and blow it again to form the rough bottle; the existing stamping assembly is made of The die, the mouth ring and the punch are composed of three parts, but the existing stamping assembly will cause many problems due to the unreasonable structural design, which will affect the processing quality of the bottle. [0003] For example, if the stroke of the existing punch is too long, it will not only increase the pressure of the punch, but also be unfavorable for controlling the weight of the product. Contents of the invention [0004] The present invention overcomes the shortcomings of the...
