AI Technical Summary

Problems solved by technology

This method has the following problems: First, the cutting accuracy is low, especially for arc-shaped material pieces, and the dimensional accuracy cannot meet the technical requirements for material lap joints; There is air residue in the joint part, forming air defects, which seriously affects the performance and reliability level of the machine; third, the quality of the chamfering depends entirely on the operator's operation level and experience, and the individual products have large differences, and the lap joint edge disengagement defect occurs from time to time; Fourth, the work efficiency is low, which has become the production bottleneck of the insulation layer manufacturing

Embodiment 1

[0032] Example 1: A thermal insulation material requires a thickness of 5mm and a diameter of 300mm:

[0033] Put the rolled thermal insulation material flat on the heat preservation platform on the base, control the temperature of the thermal insulation material to 7±2°C, adjust the positions of the gantry frame and the slide frame in turn, so that the cutting head is located above the piece to be cut, The universal wheel presses the heat insulation material, inputs parameters into the control system, and controls the angle, direction, travel speed and rotation speed of the cutting knife (in order to ensure the accuracy of the parameters, the process parameters can be explored before the production of the formal product, so as to obtain the best results. Optimum parameters), start it, and the cutting can be completed quickly.

Embodiment 2

[0034] Example 2: A thermal insulation material is 5mm thick and 300mm in diameter, and needs to be chamfered at an angle of 45 degrees:

[0035] Put the rolled thermal insulation material flat on the heat preservation platform on the base, control the temperature of the thermal insulation material to 7±2°C, adjust the positions of the gantry frame and the slide frame in turn, so that the cutting head is located above the piece to be cut, The universal wheel presses the heat insulating material, inputs parameters into the control system, controls the angle, direction, travel speed and rotation speed of the cutting knife, and when it is started, the edge can be quickly completed.

Abstract

The invention discloses an automatic slitting machine and a slitting method thereof. The slitting machine comprises a base, wherein guide tracks are arranged on two sides of the base; a portal frame is mounted on the guide tracks; a slide track is mounted on a cross beam of the portal frame; a slide block is mounted on the slide track and is connected with a slitting machine head seat; and a slitting machine head is mounted on the slitting machine head seat. When the automatic slitting machine is used, a rolled thermal insulation material is flatly placed on the base, the positions of the portal frame and the slide block are successively adjusted so that the slitting machine head is positioned above the thermal insulation material to be slit, then the angle, the direction, the traveling speed and the rotating speed of a slitting knife are controlled to slit the thermal insulation material, and finally, clipping and chamfering to the thermal insulation material are finished. The slitting machine has been applied to various products successfully, the dimension precision of cut slices is + / - 0.1 mm, and the surface of a cutting part is flat; a landing edge part does not have air defects; the clipping period of the slices of the single product is shortened within 2 hours from the original 32 hours; the quality of the product meets design requirements; and the product has been passed the test.

Description

technical field [0001] The invention belongs to the technical field of manufacturing thermal insulation layers of solid rocket motors, and in particular relates to an automatic cutting machine and a cutting method thereof. Background technique [0002] The thermal insulation material belongs to the rubber-based composite material reinforced by particles and fibers, and has flexible and high elastic properties. During construction, it needs to be cut according to design requirements. There are two main steps in the cutting of thermal insulation materials, one is to cut and shape according to the calculated shape and size, and the other is to chamfer the edges according to the requirements of lap joints. Now adopt the manual cutting method, first roll into pieces according to different thickness requirements, first mark the required shape with a pen, then cut with a blade or scissors, and finally use a cobbler's knife to cut the right-angled edge into a beveled edge. This me...
