Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the movable extrusion die set of the present invention includes an extrusion die 2 fixed on a lower die plate 1, and an extrusion punch 5 matched with the extrusion die, wherein a correction die 5 capable of pressing down a blank placed in the extrusion die 2 for correction after being extruded by the extrusion punch is installed above the lower die plate, the correction die is installed on a correction die support 4 capable of being driven to move towards X, Z, the correction die support is slidably and vertically installed on the lower die plate 1, and the correction die is located above the extrusion die at an initial position and is coaxially arranged; and the lower template is provided with a discharging mechanism capable of moving in the X direction.
The further technical improvement is that the correcting die bracket is connected with correcting hydraulic cylinders 3 which are positioned at two opposite sides of the extrusion female die and are not arranged in the X direction, and the correcting hydraulic cylinders drive the correcting hydraulic cylinders to move and lift in the Z direction; the X-direction arranged sliding installation frame for installing the correcting hydraulic cylinder 3 is connected with the X-direction arranged moving hydraulic cylinder, and the moving hydraulic cylinder can drive the sliding installation frame to move on the lower template in the X direction so as to drive the correcting hydraulic cylinder to move in the X direction.
Specifically, the number of the correcting hydraulic cylinders is two, and may also be other numbers, such as four, and two are arranged on each side, which is not limited specifically.
In a further technical improvement, the discharging mechanism comprises a discharging plate 10 coaxially positioned right above the correcting die and a discharging plate supporting rod 6 which supports the discharging plate above the lower die plate and can move in the X direction under the driving energy.
It should be noted that the stripper plate is a conventional part for separating the extrusion punch from the formed counter-extrusion workpiece, and when the extrusion punch returns, the stripper plate moves upwards to allow the extrusion punch to pass through but not the workpiece because the diameter of the stripper hole on the stripper plate is smaller than that of the workpiece, so that the purpose of unloading is achieved, and the details are not described for the conventional technology.
The technical improvement is that the stripper plate support rods 6 are multiple and form two groups, and the two groups are respectively arranged on the outer sides of the correcting hydraulic cylinders along the X direction. Specifically, each group is at least two and is arranged at intervals
The technical improvement is that the bottom end of the stripper plate supporting rod is provided with a guide part, and the lower template is provided with a pair of oppositely arranged guide grooves (such as T-shaped grooves), and the cross section of each guide groove is matched with the shape of the guide part.
The action flow is as follows:
the initial position is shown in fig. 2-3. First, the hydraulic displacement cylinder 9 pushes the correction die out of the range of the extrusion die 2, as shown in fig. 4 to 5. And putting the hot blank into the extrusion female die 2, and moving the hydraulic cylinder 9 to pull the correction die to the coaxial position of the extrusion female die 2. The extrusion punch 7 is moved downward and pressed against the calibration die 5 so that the billet is extruded downward by about 50mm, calibrating the billet. The jack cylinder is now compressed as shown in figure 6. The extrusion punch 7 is returned until it leaves the correcting die 5, and the correcting die 5 is simultaneously lifted up by the correcting cylinder 3. The mobile hydraulic cylinder 9 pushes the correction die 5 again, moving out of the range of the extrusion female die 2. As shown in fig. 7. The extrusion punch 7 moves downward to extrude the straightened billet, and the extrusion is completed as shown in fig. 7. 7 return strokes of extrusion drift, through stripper 6 with extruded article and 7 separation of extrusion drift, the extruded article drops into the extrusion die. The stripper 6 is pushed back by the stripper cylinder 8 and out of the area of the extrusion die 2, as shown in fig. 8. The extrusion piece is taken out, a new blank is put in, and the next extrusion is started.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
