Vacuum N-shaft N-knife ring-shaped rubber cutting machine

Abstract

The invention relates to a vacuum N-axis N-cutter ring-shaped rubber cutting machine, which consists of a machine table, a main shaft operation device, a vacuum device, a workpiece loading and clamping device, an automatic product unloading device, a cutter motion device and a program control device, wherein the main shaft operation device consists of N main shafts and a spindle and a main shaft transmission device which are connected with the N main shafts, the spindle is sleeved with a to-be-cut rubber workpiece with a ring-shaped cross section, and the transmission device drives the N main shafts to rotate synchronously; the cutter motion device comprises a linear worktable, a servo motor and a feed cylinder, the vacuum device is connected with an inner cavity of the spindle of the main shafts of the cutting machine through pipes and a rotary connector, and the spindle is provided with a row of exhaust holes; the exhaust holes of the spindle are exhaust holes used for the vacuum absorption of the ring-shaped rubber workpiece on the spindle and the fixation of the ring-shaped rubber workpiece on the spindle; the automatic product unloading device consists of a material returning cylinder and a material unloading sleeve linked with the material returning cylinder; and the workpiece loading and clamping device consists of a oblique bottom material box, a roller, a stepper motor, a bracket, a photoelectric sensor, and a tail bracket cylinder part.

Description

technical field [0001] The invention relates to a high-efficiency rubber cutting machine with automatic production process, especially a vacuum N-axis N-knife cutting equipment for ring-shaped rubber cutting. technical background [0002] With the needs of national economic construction and the development of rubber and machinery industries, the application of rubber gaskets and ring-shaped rubber miscellaneous parts is becoming more and more extensive, and the requirements for their performance are also getting higher and higher. Therefore, how to improve the efficiency of the rubber gasket cutting machine and improve the cutting accuracy of the product has become very important. In this regard, some rubber cutting machines have appeared on the market, and the patents of some rubber cutting machines have also been disclosed. [0003] CN2557301 discloses a rubber cutting machine, which is provided with a main shaft, a tail tip seat, a tool holder, and a workpiece mandrel in...

AI Technical Summary

Problems solved by technology

[0008] There are some defects in the rubber cutting machines currently on the market. First, the cutting speed of the single-axis single-knife machine is slow and the work efficiency is low, which cannot meet the needs of mass production.

Secondly, the accuracy of the rubber gasket products made by most cutting machines is not high. The key reason is that ordinary cutting machines use the elastic shrinkage properties of rubber to attach the workpiece to the mandrel of the main shaft for cutting. The elastic recovery of the product, so the actual shape, size and cutting of the product have changed, and the accuracy of the product is difficult to guarantee

Again, most of the current cutting machines are not highly automated
