An automatic edge trimming machine for multi-standard o-rings

Abstract

The invention discloses an automatic trimming machine for multi-standard O-shaped sealing rings. The device includes a machine base, a trimming table, a driven wheel assembly, a driving wheel assembly, a linear module, a tool assembly, and a man-machine interface. The edge trimming workbench is installed on the machine base, and is used for installing the driven wheel assembly and the cutter assembly. The driven wheel assembly and the driving wheel assembly together realize the installation and driving of the sealing ring. Under the control of the control system, the speed regulating motor drives the driving wheel to rotate and drives the sealing ring to move. The linear module is used to drive the driving wheel assembly to move left and right to realize the tension control of the sealing ring. The cutter assembly is used for trimming the sealing ring; the trimming knife has two symmetrical blades up and down, which can trim the upper and lower sides of the sealing ring at the same time. The multi-standard O-ring automatic trimming machine of the present invention is simple in structure, easy to operate, can quickly and accurately complete the automatic trimming of O-rings of different specifications and sizes in relatively large specifications, and improves the trimming efficiency.

Description

technical field [0001] The invention specifically relates to a grinding and polishing equipment, in particular to an O-shaped sealing ring trimming machine. Background technique [0002] In the production process of rubber products, in order to prevent lack of rubber, the rubber filled in the mold cavity will maintain a certain excess. At the stage of molding vulcanization, the rubber material quickly fills the mold cavity, and the excess rubber material overflows through the parting surface of the mold or the joint with the metal insert to form burrs. Once the burr is formed, it must be trimmed to get a good product, so that the product has a neat and beautiful appearance. [0003] At present, manual trimming is mostly used, that is, the operator holds a knife and gradually removes the flash along the outer and / or inner edges of the product. Especially compared to soft rubber parts, it is difficult to fix them better through mechanical structures, and then quickly trim th...

Problems solved by technology

However, the manual trimming method is time-consuming, labor-intensive and inefficient. It is easy to leave tooth marks and gaps on the product body, resulting in scrapping. The quality is difficult to guarantee, and the product consistency is poor.

There are also some sealing ring trimming machines on the market. Although the function of automatic trimming has basically been realized, there are generally two problems: first, only small sealing rings can be fixed and trimmed, and for diameter For larger sealing rings, no effective method has been found so far; second, the current method of fixing the sealing rings is to use mold fixing, and put the sealing rings into the grooves of the corresponding molds

Although this equipment uses the groove chuck to solve the problem of fixing the soft sealing ring, it needs a large number of molds to meet the fixing of sealing rings of different specifications and requires frequent replacement of molds; at the same time, manual adjustment of the tool position is used. way, it is difficult to guarantee product quality, and the production efficiency is low
