Detailed Description
In order to make the utility model realize that the technical means, technical characteristics, utility model purpose and technological effect are easily understood and known, combine specific figure below, further explain the utility model.
As shown in fig. 1 to 4, for the utility model discloses a bender automatic adjustment lower mould open position device, including preceding clamp plate 1, back clamp plate 2, voussoir group 3, drive adjusting device 4 that voussoir group 3 removed.
The front pressing plate 1 and the rear pressing plate 2 are positioned on two sides of a lower die holder 5 of the bending machine and are transversely and oppositely fixed on two sides of a workbench 6 of the bending machine; the inner sides of the front pressing plate 1 and the rear pressing plate 2 are both provided with oil cylinders 7, and the oil cylinders 7 are connected with the lower die holder 5 of the bending machine; the wedge block group 3 is arranged below a lower die holder 5 of the bending machine; the adjusting device 4 is located at one side of the wedge block set 3 to drive the wedge block set 3 to adjust the position of the lower die holder 5.
The specific structure and connection mode of each component in this embodiment are as follows:
the front pressing plate 1 and the rear pressing plate 2 in the embodiment can be an independent whole pressing plate arranged on the front end face and the rear end face of the workbench 6, and can also be sectional pressing plates, namely a plurality of front pressing plates 1 and rear pressing plates 2 are arranged on the front end face and the rear end face of the workbench 6, and the specific structures and the sizes of the front pressing plates 1 and the rear pressing plates 2 are designed and customized according to the size of the bending machine.
The number of the oil cylinders 7 in the embodiment is determined according to the size of the lower die holder 5, and the oil cylinders in the embodiment are multiple and are arranged on the outer side surfaces of the front pressing plate 1 and the rear pressing plate 2 at equal intervals in parallel to tightly push the lower die holder 5 by applying external force uniformly. In this embodiment, the lower mold support 5 is provided with a plurality of retractable holes 51 into which the retractable rods 71 of the oil cylinders 7 extend, so that the lower mold support 5 is fixed by applying an external force uniformly.
The wedge set 3 in this embodiment includes a first wedge 31 and a second wedge 32 engaged with the first wedge 31, and a guide strip 33 is further provided on an inner side of the first wedge 31 to assist the wedge set 3 to move linearly.
The first wedge 31 is located at the outer side of the second wedge 32, and the relative displacement between the first wedge 31 and the second wedge 32 is adjusted to change, so that the position of the notch of the die 51 installed in the lower die holder 5 is changed, and the accurate positioning effect is further achieved on the notch of the lower die.
The adjusting device 4 in this embodiment includes a servo motor 41 disposed outside the table 6, a ball screw pair 42 in driving contact with the servo motor 41, and a linear guide rail pair 43 located on one side of the ball screw pair 42; the upper slide block of the linear guide rail pair 43 is connected with the first wedge block 31 through a hanging pin, and a proximity switch 44 is arranged on one side of the ball screw pair 42.
