Problems solved by technology
However, this nail gun that utilizes the combination of air pressure and hydraulic pressure also has the problem of slow reset speed of the rivet piston.
[0004] Existing nail pulling guns are provided with pressure springs in the gun body relative to the tail of the pull rod piston. After the nail pulling gun completes a riveting operation, the nail pulling gun retreats under the force of the pressure spring at the tail of the pull rod piston. The return speed of the tie rod piston is entirely due to the spring force, and the hydraulic oil returns slowly, resulting in slow return of the tie rod piston, which increases the preparation time for the next riveting operation and reduces production efficiency

The invention discloses a quick restoration rivet gun which comprises a gun body and a cylinder body. The gun body is fixedly connected with the cylinder body. A piston push rod corresponds to a hydraulic oil cavity in the gun body. The quick restoration rivet gun is characterized in that a piston cavity and a sliding valve cavity are respectively formed in the cylinder body, the sliding valve cavity is composed of an upper sliding valve cavity, an air inlet cavity and a lower sliding valve cavity, the air inlet cavity is formed between the upper sliding valve cavity and the lower sliding valve cavity, the upper sliding valve cavity and the lower sliding valve cavity are respectively provided with an air hole communicated with the piston cavity, a double-head sliding valve is arranged in the sliding valve cavity, two valve heads of the two double-head sliding valve respectively correspond to the upper sliding valve cavity and the lower sliding valve cavity, a restoration spring is arranged between the double-head sliding valve and the lower sliding valve cavity, a switch ejector rod is arranged between the double-head sliding valve and the upper sliding valve cavity, corresponds to a trigger part, and is in clearance fit with the upper sliding valve cavity, and an exhaust hole is formed in the bottom of the lower sliding valve cavity. The quick restoration rivet gun is quick in restoration speed after rivet pulling, greatly shortens restoration auxiliary time, and improves production efficiency.
Description
technical field [0001] The invention relates to a nail pulling gun, in particular to a fast reset nail pulling gun. Background technique [0002] Nail pulling gun, also known as rivet gun, is mainly used for riveting of aluminum, iron, and stainless steel plates. The rivet is mainly pulled through the combination of air pressure and oil pressure, and its advantages are fast rivet pulling speed and high rivet pulling force. Pneumatic riveting guns are widely used in decoration, automobile manufacturing and refitting, containers, electrical appliances, home appliances, instruments, luggage and machinery manufacturing industries, and are currently one of the most advanced riveting tools in the world. [0003] The rivet guns on the market mainly use the pneumatic piston push rod to compress the hydraulic oil, so that the pressurized hydraulic oil filling the rivet gun body pushes the pull rod piston in the rivet gun body to retreat, thereby realizing the rivet fastening. Purpo...
