Hydraulic tool working head

A hydraulic tool working head comprising:

• a frame comprising a first section having a hydraulic cylinder area, an opposite second section and a middle section connecting the first and second sections to each other, wherein the frame comprises a one-piece metal member;
• a ram movably located in the hydraulic cylinder area and extending out of the first section of the frame towards the opposite second section of the frame;
• and
• a connection between the ram and the middle section of the frame, wherein the connection comprises the one-piece metal member at the middle section of the frame having a T shaped section along an interior facing side of the middle section which faces an area of movement of the ram between the first and second sections, and the ram comprising two cantilevered hook sections which generally face towards each other, wherein the hook sections have ends slidably located behind a head section of the T shaped section, and wherein the interior facing side of the middle section comprises two ram hook mounting slots into an end of the T shaped section adapted to allow the ends of the hook sections to be located behind the head section of the T shaped section.

A method of manufacturing a hydraulic tool working head comprising:

• providing a frame comprising a first section having a hydraulic cylinder area, an opposite second section and a middle section connecting the first and second sections to each other, wherein the middle section comprises a T shaped section along an interior facing side of the middle section which faces a ram movement area between the first and second sections;
• providing a ram comprising two cantilevered hook sections with ends which generally extend towards each other;
• inserting the ram into the hydraulic cylinder area;
• and
• locating the hook section of the ram along opposite respective exterior sides of the middle section with the ends of the hook sections extending into slots behind a head section of the T shaped section.

A hydraulic tool working head comprising:

• a frame comprising a first frame member forming at least a portion of a first section having a hydraulic cylinder area, and a one-piece second frame member connected to the first frame member, wherein the second frame member comprises a second section located opposite the first section and a middle section connecting the first and second sections to each other;
• a ram movably located in the hydraulic cylinder area and extending out of the first section of the frame towards the opposite second section of the frame, wherein the ram comprises a one-piece movable die holder member;
• and
• a movable connection between the one-piece movable die holder member and the middle section of the one-piece second frame member, wherein the movable connection comprises at least one portion of the one-piece movable die holder member wrapping around at least one exterior portion of the middle section of the one-piece second frame member to slidably attach the one-piece movable die holder member to the middle section of the one-piece second frame member.
