Steel-wire belt cut-off device for square-section bead ring

Abstract

The invention discloses a steel-wire belt cut-off device for a square-section bead ring. The device comprises an actuating mechanism and a gas-liquid power system, wherein the actuating mechanism consists of a mounting bracket, a machine nozzle, a cutter, an oil hydraulic cylinder and a cutter connector; the machine nozzle is formed at the lower part of the mounting bracket; the oil hydraulic cylinder is arranged at the upper part of the mounting bracket; the cutter is arranged on a piston rod of the oil hydraulic cylinder through the cutter connector, and a plane Alpha on which a cutter blade and the cutter are arranged is coincided with a plane penetrating the centerline L of the piston rod; the cutter blade corresponds to the outlet of the machine nozzle; the gas-liquid power system is connected with the oil hydraulic cylinder; and the gas-liquid power system is used for pushing the piston rod to move up and down to drive the cutter at the lower part of the piston rod to cut off the steel-wire belt coming out of the machine nozzle. According to the invention, the travel of the cut-off cutter is less than 10 mm, and the device can conduct closed operation to completely eliminate security risks. The service life of the cutter and the machine nozzle is 3-5 times longer than that of similar devices.

Description

technical field [0001] The invention belongs to a cutting device for cutting a steel wire belt, in particular to a device for cutting a steel wire belt used for a steel wire ring with a square section. Background technique [0002] XJL—LG series tire bead ring winding extrusion production line is used for the production of square-section bead rings such as truck tires and construction machinery tires. The cutter device of the equipment has defects such as poor operating safety, high failure rate, and high noise during use, which not only affects the normal production, but also poses hidden dangers to the health and safety of operators. [0003] Its specific analysis is as follows: [0004] Equipment original cutter device such as figure 1 As shown, it is made up of cutter 1-1, machine nozzle 2-1, cutter fixed mount 3-1, lifting cutter cylinder 4-1, bearing pin 5-1 and tension spring 6-1 etc. [0005] It works as follows: [0006] After the winding disk reaches the set nu...

AI Technical Summary

Problems solved by technology

[0008] ⑴There are serious safety hazards

Due to the large stroke range of the cutter (more than 120mm) and the limitation of the space position, safety protection facilities such as protective covers cannot be installed on this part, so it is easy to cause mechanical injury to the employee during the process of falling and lifting the cutter

[0009] ⑵There are many failure points and high failure rate, which affect the normal production

Each shift of the cutter has to move more than 3,000 times. Due to frequent movements and strong impact, it often occurs that the cutter is not working properly due to excessive wear and tear on the cutter fixing frame 3, the piston rod head of the cylinder 4, and the pin shaft 5. Work

[0010] (3) Large maintenance workload, high maintenance costs, and increased production costs

In addition to the above-mentioned faults affecting production, the alloy blade welded to the cutter and machine nozzle by brazing often breaks under frequent impacts, thereby increasing equipment operating costs

[0011] ⑷ During the working process of the cutter falling, cutting and lifting, a lot of impact noise is generated, which affects the physical and mental health of employees
