Specifically, the two trigger switches 13 respectively establish signal linkage with the carrying mechanical arm 10 and the pump body 53, when the connecting shaft 34 reversely rotates after stamping forming to drive the swinging rod 14 to swing and touch the trigger switch 13 on the mounting seat 12, the trigger signals are quickly transmitted to the control system to control the carrying mechanical arm 10 to start and execute preset actions, the ejected formed workpiece is accurately transferred into the storage box 11, the trigger switch 13 touching the bottom of the fixed rod 15 on the upper die 8 is triggered, at the moment, the trigger signals control the pump body 53 to start, and the cooling liquid in the liquid storage box 51 is sprayed to each die through the second connecting pipe 54 to realize cooling.
The working principle is that an operator transfers a hot forging piece (such as a metal blank and a metal plate) to be processed to the upper part of the molding surface of the lower die 4 through the carrying mechanical arm 10, so that the workpiece is stably placed at the top end of the abutting rod 91. The gravity of the workpiece acts on the abutting rod 91, the abutting rod 91 is driven to drive the movable seat 94 to slide downwards along the sliding groove 98, and the reset spring II 97 is compressed. Along with the downward movement of the movable seat 94, one end of the connecting rod 96 slides along the inner wall of the bar-shaped groove 95, and the connecting rod 93 pulls the positioning wheels 92 to synchronously close to the workpiece side until the positioning wheels 92 are tightly abutted with the outer wall of the workpiece, so that the automatic centering and the preliminary positioning of the workpiece are completed, and the initial position of the workpiece is ensured to be accurate.
After the preliminary positioning is completed, the hydraulic cylinder 16 is started, and the driving end of the hydraulic cylinder extends downwards and drives the upper die 8 to synchronously move downwards. In the downward movement process of the upper die 8, the mounting rod 38 fixed at the rear side thereof moves downward along with the downward movement, and then drives the first driving rack 31 at the inner side of the mounting rod 38 to vertically move downward. Since the first driving rack 31 is meshed with the second driving gear 35, the linear motion of the first driving rack 31 is converted into the rotary motion of the second driving gear 35, and the rotary motion is transmitted through the connecting shaft 34 to drive the first coaxially fixed driving gear 33 to synchronously rotate. The first driving gear 33 is meshed with the two driving racks two 39 sliding up and down in the limiting seat 32 at the same time, the rotary motion is converted into synchronous relative horizontal motion of the two driving racks two 39, and the two clamping seats 36 are pushed to be close to each other through the connecting seat 37 until the clamping seats 36 are tightly attached to two sides of a workpiece, so that clamping and fixing of the workpiece are realized, and workpiece displacement in the stamping process is avoided.
With the upper die 8 continuing to move downwards until the upper die is matched with the lower die 4, the stamping force is applied to the workpiece after clamping and fixing by utilizing the molding surface matching of the upper die 8 and the lower die 4, and the stamping forming processing of the hot forging is completed.
After the stamping forming, the driving end of the hydraulic cylinder 16 is contracted upwards to drive the upper die 8 to move upwards synchronously. When the upper die 8 moves upwards, the mounting rod 38 and the first driving rack 31 move upwards, and the connecting shaft 34 is driven to rotate reversely through the gear transmission mechanism. When the connecting shaft 34 reversely rotates, the rotating disc 71 fixedly sleeved in the middle synchronously rotates, and the two hinging rods 73 eccentrically connected with the outer periphery thereof swing to push the moving rod 74 hinged with the rotating disc to move upwards. Because the top end of the moving rod 74 and the bottom end of the ejector rod 75 are both adaptive cambered surfaces, when the moving rod 74 moves upwards, the ejector rod 75 is driven to vertically slide upwards along the inner side of the mounting seat 12, and the first return spring 76 is compressed. The top end of the ejector rod 75 penetrates through the molding surface of the lower die 4, the workpiece after stamping molding is pushed upwards, the workpiece is separated from the molding surface of the lower die 4, and automatic ejection of the workpiece is realized.
In the process of reversely rotating the connecting shaft 34, the end part of the connecting shaft penetrates through the swinging rod 14 outside the mounting seat 12 to swing synchronously, and when the swinging rod 14 touches the trigger switch 13 at the front end of the mounting seat 12, the trigger signal controls the starting of the carrying mechanical arm 10. The carrying mechanical arm 10 moves to the upper side of the lower die 4, grabs the ejected formed workpiece, and transfers the formed workpiece to the storage box 11 to finish storage, so that automatic collection of the processed workpiece is realized.
After the workpiece is stored, the hydraulic cylinder 16 continues to drive the upper die 8 to move upwards, the movable rod 63 fixed at the top of the upper die 8 moves upwards along with the upper die, and the rubber piston in the fixed cylinder 61 is pulled to slide upwards along the cylinder wall, so that the air pressure in the fixed cylinder 61 is increased. Because the check valve on the air jet pipe 64 only allows the air to be ejected outwards, the air in the fixed cylinder 61 is conveyed to the atomizing nozzle at the end part through the air jet pipe 64, and air flow is ejected to the molding surfaces of the upper die 8 and the lower die 4, so that fine scraps generated in the stamping process are blown off the die surface, and automatic cleaning of the die is realized. When the upper die 8 moves up to a preset position, the upper die 8 touches the trigger switch 13 at the bottom of the fixed rod 15, and the trigger signal controls the pump body 53 to start. The pump body 53 extracts cooling liquid from the liquid storage tank 51 through the first connecting pipe 52, distributes the cooling liquid to the second connecting pipes 54 through the conveying pipe 55 and the three-way valve, sprays the cooling liquid to the molding surfaces of the upper die 8 and the lower die 4 through the second connecting pipes 54, realizes quick cooling of the dies, and prepares for the next stamping process.
After the cooling is completed, the pump body 53 stops working, and the hydraulic cylinder 16 drives the upper die 8 to return to the initial upper position. The ejector rod 75 slides downwards to reset under the action of the elastic restoring force of the first reset spring 76, the movable seat 94 slides upwards under the action of the elastic restoring force of the second reset spring 97, the abutting rod 91 and the positioning wheel 92 are driven to reset, and the device is restored to an initial state and can carry out the processing cycle of the next workpiece.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
