2results about How to "Prevent affecting subsequent use" patented technology

The utility model relates to oil pressure machine technical field, and disclose a kind of oil pressure machine convenient to cool, including support platform, fixed mounting frame in the upper portion of support platform, cooling liquid tank fixedly installed in the bottom of support platform, through support fixed mounting in the left side of cooling liquid tank and be sent material pump, hydraulic pump fixedly installed in the upper portion of mounting frame, upper die fixedly connected in the output end of hydraulic pump, lower die fixedly installed in the upper portion of support platform, and the connecting assembly being set in the side of support platform, the connecting assembly includes the cooling mechanism being set in the lower portion of support platform, the cooling liquid tank is internally provided with stirring mechanism, the input end of be sent material pump is communicated with cooling liquid tank through absorption pipe and is set up. The utility model solves the problem that the existing oil pressure machine does not have cooling effect, so that the workpiece after stamping forming cannot be rapidly cooled, demoulding is inconvenient, and then the workpiece is taken out by artificial, and the applicability of the device is affected.

This utility model relates to the field of anchor bolt drill bit technology and discloses an adjustable soil enlargement head anchor bolt drill bit, including a drill rod, a main drill bit fixedly installed on the left side of the drill rod, and a connecting assembly disposed inside the drill rod. The connecting assembly includes an adjustment mechanism disposed inside the drill rod, a heat dissipation mechanism disposed inside the drill rod, a limiting ring slidably connected to the inner wall of the drill rod, a spring at the end away from the pressure block fixedly connected to the inner wall of the drill rod, a solid column at the outer end fixedly connected to a conical block, a micro fan input end connected to the outside through an air inlet pipe, and an exhaust pipe at the end away from the exhaust box located outside the driver. This utility model solves the problem that existing anchor bolt drill bits require different models of drill bits to meet different hole diameters during the drilling process, resulting in high operating costs, reduced construction efficiency, and limited practicality.
