Cooling device for pneumatic nail gun cushion pad

Abstract

The invention provides a cooling device for a pneumatic nail gun cushion pad, and belongs to the technical field of pneumatic tools. The cooling device for the pneumatic nail gun cushion pad solves the problems that an existing pneumatic nail gun cushion pad is prone to being damaged and is difficult to replace. According to the cooling device for the pneumatic staple gun cushion pad, a pneumatic nail gun comprises a shell, a cavity in the shell is communicated with an air inlet nozzle, and the cushion pad is located in the shell; the cooling device comprises a cooling pipe, a first cooling drum and a second cooling drum, the middle of the cooling pipe is attached to the cushion pad, a first piston is arranged in the first cooling drum, the first cooling drum is divided into a pneumatic cavity and a liquid storage cavity which are not communicated with each other up and down through the first piston, the pneumatic cavity is communicated with the cavity of the shell, the liquid storage cavity is communicated with one end of the cooling pipe, the other end of the cooling pipe is communicated with the second cooling drum, and a reset structure which can enable cooling liquid to flow back to the first cooling drum from the second cooling drum is arranged in the second cooling drum. The cooling device for the pneumatic nail gun cushion pad can prolong the service life of the cushion pad.

Description

technical field [0001] The invention belongs to the technical field of pneumatic tools, and relates to a pneumatic nail gun, in particular to a cooling device for a cushion pad of a pneumatic nail gun. Background technique [0002] Pneumatic nail guns can be used for container pallets, large wooden packing boxes to make fences, wooden structure connections for houses, wooden furniture and other wooden structure connections. It can be stapled quickly and saves labor costs. [0003] Existing pneumatic nail guns, such as Chinese patent literature discloses a pneumatic nail gun [Patent No.: 02241710.9; authorized announcement number: CN2550136Y] with dual-purpose functions of cement and wood, which includes a housing, a cylinder, a cylinder head, a balance valve, Gun cover, gun head, firing pin, nail box, trigger, air intake nozzle, there is a buffer pad between the cylinder and the shell, there is an O-ring between the shell and the cylinder head, and there is an O-ring betwee...

AI Technical Summary

Problems solved by technology

[0004] For the pneumatic nail gun with this structure, when the compressed air is introduced into the gun body from the air inlet, the trigger is pulled and the trigger rod on the gun head is pressed against the nail object, at this time the air valve at the rear of the balance valve is closed, and the balance valve Separated from the cylinder, the compressed air quickly enters the cylinder, pushing the striker to hit the tail of the nail in the nail box, so that the nail is shot out, so as to achieve the purpose of connecting objects with the nail; when the pneumatic nail gun is in use, it generally fires continuously There are multiple nails, and the cushion is made of rubber material. Every time when the nail is shot, the striker will hit the cushion, and the cushion will be deformed after being impacted. The cushion relies on its own deformation to relieve the impact from the striker. Deformation Heat will be generated during the process, and the shell of the pneumatic nail gun is a closed cavity. The heat generated by the collision cannot be dissipated to the outside world. The collision will heat up the cushion pad, accelerate the aging of the cushion pad, and accelerate the damage of the cushion pad. The service life of the pad is short. Once the cushion pad is damaged, it will cause the product function to fail. You need to find a professional or go to a professional maintenance point to replace it, which is troublesome.
