Embodiment 2

[0029] This embodiment is optimized on the basis of embodiment 1, such as Figure 5-Figure 8 As shown, the inner side of the outer ring cutter 2 is provided with a limit step along the circumferential direction, the bush 4 extends between the outer ring cutter 2 and the inner ring cutter 1 and a limit receiving platform is correspondingly provided. The limit receiving platform on the top of the bushing 4 can be stuck on the inner limit step of the outer ring cutter 2 .

[0030] Further, the bushing 4 is a tubular structure, and the thickness of the bottom of the bushing 4 is equal to the thickness of the asbestos washer 5 .

[0031] The present invention has reasonable design structure and convenient operation. When processing the asbestos washer 5, the sheet material of the asbestos washer 5 can be punched into an annular washer at one time. Pop-up, improve processing efficiency.

[0032] Other parts of this embodiment are the same as those of Embodiment 1, so details are n...

Embodiment 3

[0034] This embodiment is optimized on the basis of embodiment 1 or 2, as figure 1 As shown, the punching ends of the outer ring cutter 2 and the inner ring cutter 1 are flush. The inner ring cutter 1, the outer ring cutter 2 and the bushing 4 are all made of die steel and prepared through quenching-tempering treatment; the spring 3 is made of spring 3 steel wire and subjected to low-temperature tempering to eliminate stress get. The inner ring cutter 1, the outer ring cutter 2 and the bushing 4 are all made of mold steel, and the strength and wear resistance of the mold are improved after quenching and tempering. The spring 3 is made of spring 3 steel wire and tempered at low temperature. Stress relief, dimensional and elastic stability.

[0035] Other parts of this embodiment are the same as those of Embodiment 1 or 2 above, so details are not repeated here.

Abstract

The invention discloses a punching tool of an asbestos washer for an ignition electric nozzle. The punching tool comprises an outer ring cutter, an inner ring cutter, a spring and a bush. The outer ring cutter sleeves the outer side of the punching end of the inner ring cutter, one end of the outer ring cutter is fixedly connected with the inner ring cutter, a punching cavity is formed between theouter ring cutter and the inner ring cutter, and the width of the punching end of the punching cavity is the same as the thickness of the asbestos washer. The bush is slidably arranged in the punching cavity, the bush is connected with the top end of the punching cavity through the spring, a limiting device corresponding to the bush is arranged on the inner side of the outer ring cutter so as toprevent the bush from sliding out of the punching cavity, and the sliding stroke of the bush is larger than or equal to the height of the asbestos washer. The punching tool of the asbestos washer forthe ignition electric nozzle is reasonable in design structure and convenient to use and operate, when the asbestos washer is machined, an asbestos washer plate can be punched into an annular washer at a time, after the spring is punched and formed, the asbestos washer can be automatically ejected out of a combined die, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of punching devices, and in particular relates to a punching tool for an asbestos washer for an ignition tip. Background technique [0002] Aeroengine ignition nozzle is a product that realizes energy conversion in the engine ignition system. It discharges the high-energy pulse voltage from the ignition device to the side electrodes through the center electrode, breaks down the air, generates electric sparks, and ignites the combustion chamber in the engine. The mixture of oil and air to start the aeroengine. The asbestos gasket for the ignition nozzle is located between the porcelain part inside the nozzle and the force-bearing end of the nozzle, which can buffer the external torque and protect the porcelain tube. Its existing processing method is to utilize two toolings of the inner and outer ring diameters of the gasket to be punched into shape. During processing, the inner ring is punched out with the s...
