Double-cylinder nailing method

Abstract

The invention discloses a double-air-cylinder nailing method. The method comprises the steps that A, a needle tube assembly is pressed till a preset condition is met; b, driving a main piston to move from the front end to the rear end of the main air cylinder through the firing pin, meanwhile, moving an auxiliary piston from the rear end to the front end of the auxiliary air cylinder, enabling high-pressure gas in the main air cylinder to enter the auxiliary air cylinder, and enabling the firing pin to enter a limiting state when the firing pin moves to a set position; c, the auxiliary piston moves from the front end of the auxiliary air cylinder to the rear end of the auxiliary air cylinder, so that the high-pressure gas in the auxiliary air cylinder enters the main air cylinder till the pressure of the high-pressure gas in the main air cylinder reaches a set value; and D, limiting of the firing pin is relieved, the main piston moves at a high speed from the rear end of the main air cylinder to the front end of the main air cylinder under the driving effect of the high-pressure gas in the main air cylinder, and the firing pin is driven to instantly shoot out the shoot nail preset in the needle tube assembly. According to the method, the nailing power can be automatically adjusted according to needs, and the micro-leakage amount can be automatically compensated when gas in a cylinder is subjected to micro-leakage, so that the better nailing power is ensured; and meanwhile, the product structure is simplified, and the size is reduced.

Description

technical field [0001] The invention belongs to the technical field of nailing, and in particular relates to a double-cylinder nailing method. Background technique [0002] A nailer is a fastening tool that uses blank bullets, gas or compressed air as power to drive nails into buildings. Compared with the traditional methods of pre-embedding and fixing, drilling and pouring, bolting, welding, etc., the nailer has many advantages, such as: it is convenient for on-site and high-altitude operations, fast operation, and short construction period, which can greatly reduce the labor intensity of workers. Reliable and safe, save money, reduce construction costs, and even solve some construction problems that were difficult to solve in the past. [0003] Double-cylinder electric nail driver is a commonly used nail-shooting fastening technology. Because it can effectively and stably achieve nail-shooting fastening, it is more and more widely used in the construction industry or othe...

AI Technical Summary

Problems solved by technology

[0005] Firstly, this technology uses a crank-rocker structure for gas compression energy storage, but this structure has difficulties in achieving effective compression of high-pressure gas , resulting in less nailing power

In order to improve the nailing power, the volume of the magnetic parts must be increased, but this will lead to an increase in the weight and volume of the equipment.

[0006]Secondly, this technology can also drive the adjustable valve plug to change the size of the air chamber cavity of the additional small cylinder by turning the screw mechanism to adjust the nailing power However, due to the small volume of the small cylinder itself, it also has the problem of a small adjustable range of power

[0007]Finally, when the gas in the cylinder leaks slightly, it cannot realize the automatic compensation of the gas, which will lead to the decrease of nailing power
