Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, for the utility model discloses a frock for flattening die-cut burr, including frame 1, frame 1 is "concave" style of calligraphy and its recess sets up along the horizontal direction. A lower pressing tool 2 is fixedly arranged on the rack 1, an upper pressing tool 3 is arranged on the rack 1 and is lifted right above the lower pressing tool 2, and a hydraulic cylinder 4 for driving the upper pressing tool 3 to move along the vertical direction is also fixedly arranged on the rack 1. The bottom of the upper pressing tool 3 is fixed with an extrusion block 5, the extrusion block 5 and the lower pressing tool are arranged in a vertically staggered mode, and two mutually close edges of the extrusion block 5 and the lower pressing tool 2 are mutually parallel and located on the same vertical surface. Frame 1 is gone up and is fixed in extrusion piece 5 under and is provided with flexible post 6, and 6 inner chamber fixedly connected with reset spring 7 of flexible post, the fixed stopper 8 that is provided with in 6 tops of flexible post, stopper 8 top are higher than down tamp 2 and are close to stopper 8 one end under the spring is in natural state. When flattening die-cut burr operation, the sheet metal component that will treat processing is placed under on tamp 2, and align its shear plane with the laminating of stopper 8, tamp 2 downstream under the driving motor drive, in the motion process, extrusion piece 5 and stopper 8 contact each other, press stopper 8 to its top be less than down tamp 2 and be close to stopper 8 one end, an arris that is close to tamp 2 on the extrusion piece 5 this moment plays a role, take place shearing action with die-cut face, and in the motion process constantly with die-cut face on die-cut burr flatten on die-cut face, accomplish the getting rid of die-cut burr.
The end of the upper end face of the lower pressing tool 2, which is far away from the limiting block 8, and the end of the bottom of the upper pressing tool 3, which is far away from the limiting block 8, are inclined downwards by 30-50 degrees. One end of a processing molded surface consisting of the upper end surface of the lower pressing tool 2 and the lower end surface of the upper pressing tool 3 inclines downwards, and a certain angle is formed between the punching surface and the extrusion motion direction of the extrusion block 5, so that the extrusion block 5 can conveniently flatten punching burrs on the punching surface.
Referring to fig. 1 and 2, the fixed spacing 9 that is provided with of die-cut face direction along the sheet metal component that the perpendicular to was treated to process of 2 up end of holding down press, spacing 9 and last holding down press 3 are crisscross setting from top to bottom, and spacing 9 is not fixed to be set up on the direction of motion of last holding down press 3 promptly, and when the sheet metal component of the downstream processing of last holding down press 3 removed burr operation, spacing 9 can not produce the interference, influences the deburring effect. On the contrary, spacing 9 and stopper 8 mutually perpendicular, when arranging the sheet metal component in the processing position, spacing 9 and stopper 8 mutually support, will treat that the sheet metal component of processing fixes on the processing position better, make its die-cut face laminate with stopper 8, are favorable to improving the effect of follow-up die-cut burr that flattens. The joint of the lower end face of the upper pressing tool 3 and the extrusion block 5 is provided with a chamfer 10, and the chamfer 10 flattens the punching burrs close to one end of the lower end face of the upper pressing tool 3 on the punching face inwards in the movement process of the extrusion block 5, so that the burr removing effect is further improved.
Referring to fig. 1, a fixing plate 11 is fixedly disposed between the upper press 3 and the hydraulic cylinder 4 and between the lower press 2 and the frame 1, and the upper press 3, the lower press 2 and the telescopic column 6 are respectively fixed on the corresponding fixing plate 11 by bolts. Go up tamp 3 and tamp 2 down and can dismantle the setting on fixed plate 11, when the deburring demand to the sheet metal component of treating processing of different shapes, the supporting tamp 3 and the tamp 2 down of quick replacement to make whole device have better processing adaptability. Two parallel and vertical slideways 12 are fixedly arranged on the frame 1, the two slideways 12 are respectively positioned at two sides of the upper pressing tool 3, and two sides of the upper pressing tool 3 respectively extend into the two slideways 12 and are movably clamped and connected with the slideways. When the hydraulic cylinder 4 drives the upper pressing tool 3 to move, the slide rail 12 limits the moving direction of the upper pressing tool and can only move along the length direction of the slide rail 12, namely the vertical direction, so that the deflection of the upper pressing tool 3 and the extrusion block 5 on the upper pressing tool in the moving process is reduced, the punching surface of a sheet metal part to be machined cannot be accurately aligned, the burr removing effect on the punching surface of the sheet metal part is influenced, and when the deflection is serious, the sheet metal part to be machined can be even damaged.
Referring to fig. 1, an adhesive layer 13 is fixedly arranged on the upper end surface of the lower pressing tool 2 along the length direction of the limiting strip 9, and the adhesive layer 13 plays a role in buffering and can relieve the pressure effect of the upper pressing tool 3 on the sheet metal part to be processed; simultaneously glue film 13 can also increase the sheet metal component of treating processing and push down the frictional force between the utensil 2, after treating that the machined part is arranged in the station of processing, glue film 13 can alleviate the sheet metal component of treating processing and follow the phenomenon that 2 upper surfaces of lower tamp slided downwards and break away from the processing position because of the action of gravity, is favorable to improving the deburring effect of device.
The utility model discloses a theory of operation and beneficial effect do: on the sheet metal component that will treat processing is arranged in holding down press 2, and the die-cut face of the sheet metal component that will treat processing aligns with stopper 8, 3 downstream of holding down press in pneumatic cylinder 4 drive, go up the in-process that 3 downstream of holding down press, extrusion piece 5 constantly is close to holding down press 2, push down stopper 8 downwards earlier, then contact with the die-cut face of the sheet metal component that treats processing, inwards flatten the burr on it, after flattening completely, drive hydraulic cylinder 4 and lift up holding down press 3, take out the sheet metal component after the burr removal. The utility model discloses an go up tamp 3 and be close to the extrusion each other between the tamp 2 down, flatten die-cut burr on the face of punching, reach the effect of deburring, the device is simple, through the mode of back processing, effectively solves the problem of die-cut burr, and is efficient, uses manpower sparingly greatly.
The above, only do the preferred embodiment of the present invention, not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
