Chain riveting method utilizing oil pressure

Abstract

A chain riveting method utilizing oil pressure includes step 1, placing a chain with pins into a chain passage, aligning a first chain link required to be riveted to a riveting die; step 2, starting a hydraulic cylinder and a moving plate driving device by a control device, and enabling the hydraulic cylinder to drive the riveting die to realize primary riveting; step 3, driving a moving plate to drive the chain to move by the moving plate driving device after finishing the primary riveting; and step 4, repeating the step 2 and the step 3 to complete riveting of the whole chain. By combination of a PLC control device and an oil pressure system, full-automatic, intelligent and multifunctional riveting can be realized, four-side riveting and two-side riveting can be realized, and by the chain riveting method, one link of the whole chain can be free of riveting while the other links are riveted, so that the chain can be cut off conveniently for subsequent detection.

Description

technical field [0001] The invention relates to the chain manufacturing industry, in particular to a method for riveting a chain head by using oil pressure. Background technique [0002] In the chain manufacturing industry, the assembled chain must be riveted. However, because the current chain riveting equipment adopts the principle of mechanical linkage, the design of the riveting machine is complex in structure and bulky, and the strength and speed of mechanical stamping riveting are completely unacceptable. control, the quality of the riveting head cannot be adjusted to the best state, and all the chain links are riveted, and the function of skipping the joint cannot be realized, resulting in a lot of waste. In addition, the noise of mechanical stamping is large, which can no longer meet the requirements of construction of energy-saving and environmental protection. According to the requirements of the society, the equipment transformation of the chain manufacturing indu...

Problems solved by technology

However, this kind of riveting head machine can only adapt to the riveting heads of small and medium chains. If a larger chain needs to be riveted, the up and down movement range of the riveting head frame needs to be increased, the pitch of the chain is increased, and the size of the feed plate needs to be enlarged. Whether it is the cam that drives the riveting head frame or the driving cam that drives the mobile version, the specifications need to be greatly increased, and it is inevitable to design a large and complex riveting head machine.

Moreover, such a riveting machine has no flexibility at all. The 4 riveting dies or 2 riveting dies connected to the riveting head frame can only be moved up and down with the riveting head frame, and all of them are passively chamfered against the chain. head, instead of four-sided riveting head and two-sided riveting head for the chain according to the needs

And it is impossible to realize the jumping riveting head. In the subsequent chain cutting process, because the pin shaft of the chain with the cut off head is riveted, it cannot be ejected smoothly by the cutting device, causing related connection damage, so as to manufacture a 50-section chain. Take the chain as an example, every 50 chains will lose a chain in the subsequent cutting process, resulting in great waste

[0004] To sum up, in the current chain manufacturing industry, chain riveting heads are far from meeting people's requirements for the environment, chain quality, and low production loss.
