Manual hydraulic pressure strong pulling rivet gun

Abstract

The invention belongs to a powerful hand riveter and particularly relates to a manually-operated hydraulic powerful riveter, which comprises a machine body, a push-and-pull switching device and a riveter head, and is characterized in that the machine body is a hydraulic machine body mainly composed of a fixed handle, a movable handle, an oil storage bag and an oil return valve. The push-and-pull switching device consists of a piston, a cylinder sleeve, a bar, a rigging screw and a connecting sleeve. The riveter head mainly comprises a clamping sleeve, a three-jaw, a top core and a riveter head sleeve. The hand riveter has the beneficial effects that the structure is unique; the riveting action is completed by using the reinforcement of the hydraulic machine body for the first time; the exerted force is strong; the use is convenient; the hand riveter can be used for large-diameter self-plugging rivets, particularly for the riveting of steel rivets; the riveting strength is enhanced; the scope of riveting application is expanded; no electricity or compressed air is needed for supplying power; the hand riveter is energy-saving, environment-friendly, and particularly suitable for use in operation places such as the field, high altitude, underwater, etc.

Description

technical field [0001] The invention belongs to a strong riveting gun, in particular to a manual hydraulic strong riveting gun. Background technique [0002] At present, there are only manual rivet guns, electric rivet guns and pneumatic rivet guns. The manual riveting gun relies on manpower to complete the riveting of blind rivets. Due to the small output, only aluminum rivets can be riveted, and the connection strength is low. It can only be used for thin plates or riveting that does not require a firm connection, and the use is limited. Although electric and pneumatic rivet guns can rivet large-diameter aluminum rivets or steel rivets, the structure is complex and the cost is high. Moreover, because of the need for electricity or compressed air as power, there are many inconveniences in use. SUMMARY OF THE INVENTION [0003] The present invention mainly aims to overcome the above-mentioned deficiencies of the prior art, and provides a manual hydraulic strong riveting g...
