Rubber sealing ring bevel cutting device

Abstract

The application relates to the technical field of cutting equipment, and discloses a rubber sealing ring bevel cutting equipment, which is used to solve the problem that the rotary tearing of the cutting knife to the bevel ring-shaped excess material affects the cutting quality of the sealing ring bevel. The sealing ring is pressed into the clamping groove seat by the pressing ring plate to a certain extent through the arrangement of the placing mechanism and the pressing mechanism. Then, the clamping groove seat drives the sealing ring and the pressing ring plate to rotate, so that the pressing ring plate pressed downward can limit the rotation of the bevel ring-shaped excess material through the contact friction force and the pressure effect in the process of cutting the sealing ring by the cutting knife. Therefore, the probability that the cutting quality of the sealing ring bevel is affected is reduced. In addition, the contact stiffness of the sealing ring and the clamping groove seat is increased due to the vertical pressure during the cutting, so that the elastic rebound of the sealing ring at the end of the cutting is inhibited, and the tearing rate of the cutting position of the sealing ring is further reduced.

Description

[0001] The application relates to the technical field of cutting equipment, in particular to a rubber sealing ring bevel cutting equipment. BACKGROUND

[0002] The rubber sealing ring is suitable for hydraulic systems, pneumatic devices, reciprocating oil cylinders and the like, and in order to meet specific sealing requirements, a cutting equipment is usually used to cut the rubber sealing ring at an angle, so as to optimize the sealing performance, installation convenience and environmental adaptability through the inclined cut.

At the same time, in the process of the cutter extending into the sealing ring and cutting the sealing ring by relative rotation, the negative pressure suction force of the inner hole, the outer hole and the bottom hole on the sealing ring reduces the deformation degree of the sealing ring during cutting, so that the cutting quality of the sealing ring is not easily affected.

[0044] By setting the placing mechanism and the pressing mechanism, the sealing ring is extruded by the pressing ring plate to make the sealing ring tightly contact the inner hole, the outer hole and the bottom hole, so that the fixing effect of the sealing ring by the clamping groove seat is further improved, thereby further limiting the rotation of the sealing ring and the subsequent oblique ring-shaped excess material. After the sealing ring is cut, the negative pressure suction force of the inner hole disappears, and then the pressing ring plate is separated from the sealing ring, so that the oblique ring-shaped excess material is restored due to elasticity, thereby generating relative displacement with the sealing ring, thereby promoting the separation of the two. Through this action, the influence of the separation operation on the subsequent operation efficiency of the sealing ring is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0060] In use, the sealing ring to be cut is placed in the clamping groove of the clamping groove seat 30, then the output rod of the pneumatic cylinder 50 is retracted until the main top plate 51 drives the pressing ring plate 55 to approach and press down the sealing ring through the main rod 52, the secondary top plate 53 and the secondary rod 54, then the hydraulic cylinder in the cutter 2 drives the cutter to gradually extend and obliquely insert into the sealing ring, then the power motor 40 is operated to drive the driven gear 43, the integral rod 42 and the clamping groove seat 30 to rotate through the driving gear 41, and the sealing ring, the pressing ring plate 55 and the main rod 52 rotate accordingly. Through the pressing action of the pressing ring plate 55 on the sealing ring, the pressing ring plate 55 pressed will limit the rotation of the oblique ring-shaped excess material through the contact friction force and pressure during the cutting of the cutter, thereby reducing the probability of affecting the cutting quality of the sealing ring. At the same time, due to the vertical pressure on the sealing ring during cutting, the contact stiffness of the sealing ring and the clamping groove seat 30 is increased, thereby suppressing the elastic rebound of the sealing ring at the end of cutting, further reducing the tearing rate of the cutting position of the sealing ring. Finally, when the sealing ring is cut, the pneumatic cylinder 50 drives the pressing ring plate 55 to move upward and reset, the cutter in the cutter 2 is retracted and reset, and the worker takes out the oblique ring-shaped excess material and the oblique sealing ring, which is a working cycle.
