Embodiment 1
[0024] exist figure 1 , figure 2 In the shown embodiment, an adjustable mold base for a punching machine includes a rectangular base plate 2 and a mold adjusting base 1 with a rectangular box structure. The opening of the mold adjusting base 1 is connected to the base plate 2 downwards. Four guide post installation holes are arranged on the four corners, four bearing installation grooves are arranged on the mold adjusting base 1 corresponding to the four guide column installation holes, and the inner sides of the four bearing installation grooves on the mold adjusting base 1 are respectively provided with Four oil chambers 15 (see Figure 4 ). The bottom plate 2 and the mold adjusting base 1 are connected together through four sets of guiding mechanisms, which are respectively arranged at the four corners between the mold adjusting base 1 and the base plate 2. The guiding mechanisms include guiding columns 5 and sliding bearings 13, and the guiding columns 5 is fixedly con...

The invention discloses an adjustable mold base of a punching machine, which comprises a baseboard and a mold adjusting base, wherein a guide mechanism and a height adjusting mechanism are arranged between the baseboard and the mold adjusting base. The height adjusting mechanism comprises a transmission box, a large chain wheel, a first small chain wheel, a motor, a second small chain wheel, a piston, an adjusting sleeve and an adjusting seat, wherein an oil cavity is arranged on the mold adjusting base, a piston rod of the piston is fixedly connected with the baseboard, the upper end of the piston is arranged in the oil cavity, the adjusting seat is sleeved on the piston to be fixedly connected with the mold adjusting base, the adjusting sleeve is arranged to be matched with the piston, the adjusting sleeve is movably connected with the adjusting seat, and the large chain wheel is sleeved on the piston to be fixedly connected with the lower end of the adjusting sleeve. Through the technical scheme, a crank is lightened in weight, shock of the punching machine is reduced, accumulated errors of the whole machine tool are reduced, and processing accuracy of the high-speed operating punching machine is led to be greatly improved.
Description
technical field [0001] The invention relates to the technical field of punching machines, in particular to an adjustable die base of a punching machine. Background technique [0002] During the stamping process of the punching machine, the mold height needs to be adjusted according to the shape, thickness, and material of the workpiece to suit different workpieces. The accuracy and reliability of the mold height adjustment is a key factor restricting the performance of the punching machine. In the prior art, the adjustment of the height of the punching machine is mostly realized by adjusting the length of the crankshaft connecting rod and relying on adjusting the stroke of the movable die. [0003] Chinese patent literature (announcement date: September 21, 2011, announcement number: CN201979723U) discloses a punch die height adjustment mechanism, including an air motor, a worm, a worm wheel, a worm gear, and a lifting adjustment shaft. The output of the air motor The shaft...
