Rubber part production device for high-speed rail framework sealing ring

Abstract

The invention discloses a rubber part production device for a high-speed rail framework sealing ring. The rubber part production device comprises an extruder, the mold is connected to an outlet of the extruder; an inner die head; the cutting mechanism comprises a cutter, a rotating mechanism, a cutter driving assembly and a first horizontal reciprocating motion assembly; the rotating mechanism is fixedly arranged at the output end of the first horizontal reciprocating motion assembly, the cutter driving assembly is fixedly arranged at the output end of the rotating mechanism, the rotating axis, driving the cutter driving assembly to rotate, of the rotating mechanism is coaxial with the inner die head, and the cutter driving assembly comprises a driving air cylinder and a sliding rail; the cutter is fixedly arranged on the cutter fixing seat, and the driving cylinder drives the cutter fixing seat to change the distance from the rotation axis, so that the cutter is in contact with or away from a rubber tube at a mold outlet; after the cutter makes contact with the rubber pipe, the first horizontal reciprocating motion assembly drives the rotating mechanism to move from the first position to the second position in the moving direction of the rubber pipe, and the rotating mechanism drives the cutter driving assembly to rotate so that the cutter can cut the rubber pipe.

Description

technical field [0001] The invention belongs to the technical field of sealing ring production, and in particular relates to a production device for rubber parts for high-speed iron skeleton sealing rings. Background technique [0002] As the name implies, the sealing ring is used for sealing at the joint of two parts or at the position where the two parts move relative to each other. The existing sealing ring is often produced with rubber as the base material. See Figure 4-5 , Because the sealing ring is usually a ring structure, in the traditional process, the sealing ring is usually kneaded and honey-melted and then rolled to a certain thickness, and then cut into strip-shaped rubber strips 810, and slanted openings 822 are cut at both ends of the rubber strip. / 821, finally the workers spliced ​​the oblique openings 822 / 821 at both ends of the rubber strip and then used glue to bond them into a ring-shaped rubber ring 800; although the traditional molding method can mee...

AI Technical Summary

Problems solved by technology

See Figure 4-5 , because the sealing ring is often in the form of a ring structure, in the traditional process, the sealing ring is first rolled to a certain thickness after kneading and honey mixing, and then cut into strips 810, and bevels 822 are cut at both ends of the rubber strip / 821, finally the workers spliced ​​the oblique openings 822 / 821 at both ends of the rubber strip and glued it into a ring-shaped rubber ring 800 with glue; although the traditional molding method can meet the molding requirements of the sealing ring, it has the following disadvantages : 1. Cutting strips, bevel opening, bevel splicing and glue bonding all need to be done manually, and the glue curing also takes a long time, which makes the production efficiency not high, and it is more difficult for mass production ; 2. Although the method of oblique splicing and glue bonding can meet the basic requirements of the daily use of molding, but because the connection strength and fastness of the interface 820 are lower than the rubber ring itself, it is often easy to connect after a period of use. If there is a fracture at the place and the seal fails, then the life and stability of the seal ring are often difficult to guarantee, and the product quality is difficult to improve; 3. Due to the process itself, the seal ring itself cannot have sufficient strength, and some applications with high pressure or higher requirements will there will be greater difficulties

[0003] The application number is 201410275133.X, a method of manufacturing a polymer material sealing ring. The polymer material is extruded first, and then laser cutting is used to obtain the sealing ring. However, the problem is that it can only First extrude the polymer material to form a cylinder, then remove and fix the cylinder and then cut it by laser. It requires the cooperation of multiple machines to complete the production, which increases the process and requires repeated positioning, and the positioning accuracy is high. , otherwise it will lead to inaccurate laser cutting position and product defects; in addition, it will undoubtedly increase the production process, increase production costs and reduce production efficiency
