Detailed Description
The utility model provides a sheet metal component cut-out press, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the embodiment is lifted to follow with reference to the attached drawing the utility model discloses do further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1, the utility model provides a sheet metal part punching die, which comprises an upper die plate 1, a lower die plate 2 and a punch 3 arranged at the bottom of the upper die plate 1; the lower template 2 is provided with a positioning groove 4 matched with the sheet metal part in shape, and the positioning groove 4 is used for positioning the sheet metal part; the vertical projection of the punch 3 is positioned in the positioning groove 4.
The upper die plate 1 is fixed to the bottom of a press ram (not shown) of the press, and the lower die plate 2 is fixed to a table (not shown) of the press. Before punching a hole to the sheet metal component, in the constant head tank 4 was arranged in to the sheet metal component, through the location of constant head tank 4, when punching a hole at every turn, the position homoenergetic that the sheet metal component was arranged in on lower bolster 2 was accomplished unanimously to the position that the messenger was gone out the through-hole on the different sheet metal components of same specification can not have the difference, has ensured that the quality of sheet metal component can not descend.
In addition, as shown in fig. 1 and 2, the edge of the positioning groove 4 is provided with a stop column 6. The retaining pillar 6 may be provided in plurality, and the retaining pillar 6 is distributed at least on one side edge of the positioning slot 4. When arranging the sheet metal component in on constant head tank 4, block 6 and can block the sheet metal component to make the sheet metal component can pinpoint constant head tank 4 on, further ensured that the quality of the sheet metal component towards having the through-hole can not descend.
As shown in fig. 1 and 2, further, the lower template 2 is provided with an opening 5 on a side surface, and the positioning groove 4 extends to the opening 5. Set up opening 5 through the side at lower template 2, the operating personnel of being convenient for place the sheet metal component at constant head tank 4, also be convenient for simultaneously the operating personnel take away the sheet metal component from constant head tank 4 to can improve the efficiency of the operation of punching a hole.
As shown in fig. 3, further, the lower template 2 is provided with a first blanking hole 7 matched with the punch 3. Waste materials generated by punching can fall into a collecting device (not shown in the attached drawing) below the workbench of the punching machine through the first blanking hole 7, so that after each punching is finished, the waste materials generated by punching are not required to be moved out of the lower template 2 by an operator, and the efficiency of the punching operation can be improved. In addition, in order to allow the waste material produced by punching to fall into the collecting device located below the punch press table, a tunnel corresponding to the first blanking hole 7 should be opened in the existing punch press table.
As shown in fig. 1 and 3, further, the sheet metal part punching die further comprises a base 8; the base 8 is arranged below the lower template 2, and a damping spring 9 is arranged between the base 8 and the lower template 2. When punching a hole, 1 decline drive drift 3 of cope match-plate pattern impact sheet metal component, and when assaulting the sheet metal component, lower bolster 2 can receive decurrent impulsive force and compress damping spring 9 downwards, and the end back of punching a hole, damping spring 9 upwards resets and lifting lower bolster 2. Through set up damping spring 9 between base 8 and lower bolster 2, the impulsive force that lower bolster 2 received can not transmit on the workstation of base 8 and punch press for base 8 can not counteract lower bolster 2, and lower bolster 2 receives the degree of strikeing and can descend, thereby has prolonged the life of mould.
As shown in fig. 1 and 3, further, the base 8 includes an upper plate 801 and a lower plate 802; the area of the lower bottom plate 802 is larger than that of the upper bottom plate 801, and two positioning rods 10 are symmetrically arranged on the lower bottom plate 802; and the bottom of the upper template 1 is provided with a positioning cylinder 11 respectively matched with the two positioning rods 10. When the upper die plate 1 descends to drive the punch 3 to impact the sheet metal part, the positioning rod 10 is inserted into the positioning barrel 11, so that the upper die plate 1 can be accurately positioned during punching, and the punching accuracy is ensured.
As shown in fig. 3, a second blanking hole 12 corresponding to the first blanking hole 7 is further provided on the base 8. The second blanking holes 12 are formed through the upper plate 801 and the lower plate 802, thereby ensuring that the waste material produced by punching can be dropped into the collection device through the base 8 and the table of the punching machine.
In addition, the damping spring 9 is arranged at the periphery of the second blanking hole 12, and the normal falling of the waste materials cannot be influenced. Further, the damping springs 9 may be selectively provided on the upper plate 801 or the lower plate 802 according to the shape of the upper and lower forms 2.
To sum up, the utility model provides a sheet metal component cut-out press is through setting up the constant head tank on the lower bolster of mould to set up the bumping post at the edge of constant head tank, before punching a hole to the sheet metal component, in the constant head tank can accurately be arranged in to the sheet metal component, through the location of constant head tank, when punching a hole at every turn, the position homoenergetic on the lower bolster is arranged in to the sheet metal component can accomplish unanimously, thereby the position that makes the through-hole that dashes out on the different sheet metal components of same specification can not have the difference, has ensured that the quality of sheet metal component can not descend.
It should be understood that equivalent alterations and modifications can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such alterations and modifications should fall within the scope of the appended claims.
