Abstract:
The present invention has the object of providing a shot processing machine capable of constraining the spilling over and dropping of projection material to outside the projection chamber. The shot processing machine of the invention is a shot processing machine for performing surface treatment by projecting projection material onto a workpiece inside a projection chamber, comprising: a cabinet inside of which a projection chamber is formed, an opening disposed on the cabinet for loading and discharging workpieces; and a door movably attached to the cabinet, for opening and closing the opening, whereby a projection material adhesion prevention mechanism for preventing the adhesion of projection material is provided on the inside of the door.
Abstract:
A polishing device includes a processing vessel into which workpieces are charged, a fluidizing unit that fluidizes the workpieces in the processing vessel, an abrasive-feeding unit that feeds an abrasive into the workpieces, and a suction unit that generates an air flow in a direction in which the abrasive passes through the processing vessel, and recovers the abrasive by suction. The abrasive fed from the abrasive-feeding unit is allowed to pass between the workpieces charged into the processing vessel by the air flow generated from the suction unit while coming into contact with the workpieces. Accordingly, the workpieces are polished.
Abstract:
The core sand filling method comprises a step of operating an aeration air supply means, so as to float and fluidize core sand within a sand blow chamber and, when a pressure Pf of the sand blow chamber measured by the first pressure sensor reaches a first pressure, operating a compressed air supply means and a step of stopping the aeration air supply means and compressed air supply means from operating when each of the pressure Pf within the sand blow chamber and a pressure Pc within a sand storage chamber is a second pressure or higher while a differential pressure ΔP=Pc−Pf is a third pressure or lower.

Abstract:
A hanging section is installed at an upper side of a cabinet, and an autorotation mechanism rotates the hanging section around an axis of the hanging section in upward/downward directions of a device. In addition, a hanger unit hanging from the hanging section is installed in a cabinet, and a pair of frame sections is parallelly installed in series to match opening directions. Then, projection machines project a shot media toward the hanger unit. In addition, a loading/unloading device installed outside the cabinet is configured such that arm constituting a part thereof can be inserted into an opening section of the frame section of the hanger unit, and a tray on which a workpiece is placed can be conveyed. The loading/unloading device loads/unloads the tray with respect to the hanger unit by advancing and retracting the arm.
Abstract:
A warp correction apparatus includes an injection mechanism including a nozzle that performs injection treatment, an adsorption table that holds the semiconductor element substrate by adsorption at a principal surface side or a film surface side, a moving mechanism that moves the adsorption table so that the semiconductor element substrate relatively moves with respect to an injection area of an injection particle by the nozzle, an injection treatment chamber that houses the semiconductor element substrate held on the adsorption table and in the interior of which injection treatment is performed, a measurement mechanism that measures a warp of the semiconductor element substrate, and a control device that, based on a difference between a target warp amount and a warp amount measured by the measurement mechanism, performs at least either one of a setting processing of an injection treatment condition of the injection mechanism and an accept/reject determination of the semiconductor element substrate for which injection treatment has been performed.
Abstract:
A method for detecting powder is performed in a powder detection device including a pair of electrodes arranged to be opposed to each other with a gap interposed therebetween and an electric circuit electrically connected to the pair of electrodes. The method includes detecting powder filling in a case where the electric circuit together with powder and the electrodes forms a closed circuit when the powder fills the gap.
Abstract:
First, a nozzle insertion process in which a nozzle is inserted into a water cooling hole having a small diameter which is provided in a back of a mold is performed. Then, an injection process in which a mixed flow of air having a pressure ranging from 0.1 MPa to 1.0 MPa with an injection particle is jetted from a leading end of a nozzle to a distal portion of the water cooling hole. As a result, a shot peening process is performed on the distal portion of the water cooling hole.
