Double-cutter sealing strip cutting-off machine

Abstract

The invention discloses a double-cutter sealing strip cutting-off machine. The double-cutter sealing strip cutting-off machine comprises a workbench which is provided with a cutter adjusting rail anda sealing strip placement plate in the length direction of the workbench in parallel; the cutter adjusting rail is slidably provided with two cutter frames, and the same sides of the two cutter framesare connected with air cylinders located above the sealing strip placement plate correspondingly; and piston rods of the two air cylinders are downward in the vertical direction and stretch out synchronously, and cutters transversely perpendicular to the length direction of the sealing strip placement plate are detachably fixed to the lower ends of the piston rods. According to the double-cuttersealing strip cutting-off machine, through the two cutters, the two ends of the sealing strip can be cut at the same time in the natural state, the cutting length of the sealing strip meets the requirement, the machining precision of the sealing strip is improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of sealing strip processing equipment, in particular to a double-knife sealing strip cutting machine. Background technique [0002] Automobile sealing strip is one of the important parts of automobiles. It is widely used in doors, windows, body and other parts. It has the functions of sound insulation, dustproof, water seepage prevention and shock absorption, and maintains and maintains the environment inside the car, thus protecting the interior of the car. Personnel and equipment play a protective role. During the production and processing of automobile sealing strips, the sealing strips are often cut, and a cutting machine is required for cutting. Sealing strips are usually mass-produced and have more precise length specifications, so there is a higher requirement for the cutting length accuracy of the sealing strips. [0003] The Chinese patent whose authorized notification number is CN103085100B discloses a cutt...

AI Technical Summary

Problems solved by technology

[0004] The cutting equipment in the above-mentioned prior art has the following defects: the cutting equipment needs to lock and fix the sealing strip before cutting, and the cutting position will be locked and squeezed, resulting in certain deformation, especially when cutting a fixed-length sealing strip. When the sealing strip is cut, there will be a large error compared with the required length, which makes it difficult to install the sealing strip accurately, which not only results in a low product qualification rate, but also wastes materials.
