Hydraulic Crimping Tool with a Pressure Indicator

Abstract

A hydraulic crimping tool with a pressure indicator includes a pump body having a first end connected to a handle and a second end connected to a head. The pump body includes a pressure switch disposed at a side, with the pressure switch having a lever mounted thereto. The head includes a second jaw and a first jaw, with the first jaw comprising a piston, and with the piston being actuated by the pump body. The hydraulic crimping tool also includes a lower die disposed on the piston and an upper die disposed on the second jaw. The head also includes an indicator mounted thereto for displaying a pressure reading. The indicator includes a panel disposed at a side of the head and a strain gauge mounted to the second jaw. The strain gauge is electrically connected to the panel.

1 . The hydraulic crimping tool with a pressure indicator comprising:
 a pump body having a first end and a second end including a handle and a head connected thereto respectively, with the head being comprised of a first jaw and a second jaw, with the fist jaw including a piston moved by hydraulic fluid disposed in the pump body, with the piston including a lower die defined thereof, and with the second jaw including a upper die defined thereof,   a pressure switch being disposed at a side of the pump body, with the pressure switch including a lever mounted thereto such that the user can use to operate the pressure switch and;   an indicator mounted to the head for displaying a pressure reading including a panel and a strain gauge affixed to the second jaw, with the strain gauge being electrically connected to the panel.   
   
   
       2 . The hydraulic crimping tool with a pressure indicator as claimed in  claim 1  wherein the panel includes a plurality of push buttons used for powering on, powering off, setting pressure, storing pressure reading and zeroing of the indicator. 
   
   
       3 . The hydraulic crimping tool with a pressure indicator as claimed in  claim 2  wherein the indicator includes an alarm, with the alarm being adapted for warning the user that the preset pressure for the hydraulic crimping tool is obtained. 
   
   
       4 . The hydraulic crimping tool with a pressure indicator as claimed in  claim 3  wherein the indicator includes a plurality of warning lights installed on the panel, with the warning lights being adapted for representing power status of the indicator and indicating whether the preset pressure is achieved. 
   
   
       5 . The hydraulic crimping tool with a pressure indicator as claimed in  claim 1  wherein the upper die and the lower die define a space. 
   
   
       6 . The hydraulic crimping tool with a pressure indicator as claimed in  claim 5  wherein the space is in a shape of a hexagon.
