A combined knife cutting machine on a steel cord cutting production line

Abstract

The invention relates to a combined knife cutting machine on a steel cord cutting production line, which comprises a fuselage body, a rectangular lower knife and a disc upper knife; There is a lower knife seat; the rectangular lower knife is installed on the lower knife seat through the quick locking device of the lower knife; the upper disc knife is installed on the linear guide rail through the headstock, and the headstock is equipped with a servo Motor and toothed belt, the upper knife on the disc moves on the linear guide rail under the drive of the servo motor; the inner side of the upper knife on the disc is provided with a cylinder that sticks to the disc knife, and when the cylinder is pushed, the bottom of the upper knife on the disc The side of the lower knife is attached to the side of the rectangular lower knife; the inner side of the lower knife seat is provided with a refilling roller, and the refilling roller conveys the rubber material, and a material turning device is also installed on the lower knife seat; the material turning device A material-pressing device is arranged above, and the material-pressing device is installed on the beam and is located outside the upper knife on the disc. The invention is convenient to operate and convenient to assemble and disassemble.

Description

technical field [0001] The invention belongs to the technical field of tire production and processing equipment, in particular to a combined knife cutting machine on a steel cord cutting production line. Background technique [0002] At present, the belt layer and steel cord cutting machine commonly used in the market is in the form of rectangular knives on the upper and lower knives (referred to as the rectangular knives cutting machine). The working principle is similar to scissors. From an angle (such as 1°), use the falling of the upper knife to achieve cutting with the lower knife to cut or shear the steel wire and steel cord rubber. It has the advantage of high efficiency and can cut about 20 times per minute. The disadvantage is that the overall cost is relatively high, and it is troublesome to change the tool and adjust the gap between the two tools. [0003] The structure of the rectangular knife cutting machine is as follows: figure 1 and figure 2 , including t...

Problems solved by technology

[0006] In addition, before the rectangular knife cutting machine works, it is necessary to adjust the gap between the upper and lower knives in the X direction, that is, the total length of 4100mm. The gap state is about the clearance fit between the two ends of the two knives, and the interference fit in the middle part (the specific value has a gap Pre-adjustment table, that is, the coordinate value on 4100mm), it is troublesome to adjust, and you must have experience

In addition, the upper and lower rectangular knives are installed with 21 countersunk screws at the upper and lower sides, a total of 42 M16 countersunk screws. When the blade is not fast enough, these screws need to be removed when changing the knife, which is troublesome and wastes time.
