Description

Hydraulic punching machine with sliding block bottom dead center capable of being repeatedly positioned at high precision
The technical field is as follows:
the utility model relates to a sheet metal processing machinery, especially hydraulic press.
Background art:
the hydraulic punching machine is a machine for punching and shearing metal plates by pushing a sliding block to move back and forth through an oil cylinder, and different sliding block strokes and sealing heights are required to be matched according to the process requirements and the die heights of different products. At present, in the hydraulic punching machine produced in China, the position precision of the sliding block to the bottom dead center is greatly changed due to the temperature change of hydraulic oil, the sensitivity reflected by an electrical element and the compressibility of the hydraulic oil, and the position precision of the sliding block to the bottom dead center needs to be adjusted for many times, but the precision of the sliding block to the bottom dead center cannot be guaranteed, so that a hydraulic punching machine which can be conveniently, accurately and rapidly adjusted is urgently needed to guarantee the high-precision repeated positioning of the sliding block to the bottom dead center.
The invention content is as follows:
in order to overcome the not enough of current hydraulic press slider to bottom dead center repeated positioning accuracy, the utility model provides a slider bottom dead center can high accuracy repeated positioning's hydraulic press, it can eliminate aforementioned problem.
The utility model provides a technical scheme that its technical problem adopted is: the hydraulic punching machine comprises a wall plate, an adjusting screw, an adjusting nut, a worm wheel, a worm, a limiting block, a speed reducer and a hand wheel, wherein the hand wheel is arranged on the outer side of the wall plate on one side of the hydraulic punching machine, the speed reducer and a motor are arranged on the outer side of the wall plate on the other side of the hydraulic punching machine, the hand wheel and the speed reducer are connected with two ends of the worm, the worm is arranged on a worm wheel shell (the worm wheel shell is arranged on a punching machine body); the worm wheel is arranged on the adjusting screw rod, and the adjusting screw rod is provided with an adjusting nut; the limiting block is arranged on the punch slide block. The beneficial effects of the utility model are that according to the technological requirement and the mould height of different products, carry out high accuracy repeated positioning to the slider and adjust.
Description of the drawings:
figure 1 is a front view of the present design.
FIG. 2 is a cross-sectional view of the design
Figure 3 is a cross-sectional view of the present design (large stroke small closure height).
Figure 4 is a cross-sectional view of the present design (small stroke large closure height).
In each figure: the device comprises an adjusting screw rod 1, an adjusting nut 2, a worm wheel shell 3, a worm 4, a worm wheel 5, a limiting plate 6, a fine adjustment hand wheel 7, a speed reducer 8, a motor 8, a machine body 9, a sliding block 10, a guide plate 11, a guide key 12 and a wall plate 13.
The specific implementation mode is as follows:
the following description of the design is given by way of example in conjunction with the accompanying drawings.
As shown in fig. 1 and 2, the existing hydraulic press mainly comprises a body 9, a slider 10, an oil cylinder 13, a hydraulic control system, an electrical system and the like, wherein a speed reducer motor (8) is installed on the outer side of a side wall plate (13) of the body, a worm (4) is installed on a worm gear shell (3), the worm gear shell (3) is fixed on the body (9), and the worm (4) is meshed with a worm gear (5); the worm wheel (5) is arranged at the upper end of the adjusting screw rod (1), the adjusting screw rod (1) is provided with an adjusting nut (2), the adjusting nut (2) is provided with a guide key (12), and the lower end of the adjusting screw rod (1) is provided with a support; a guide plate (11) is arranged on a vertical plate in the middle of the machine body (9); a fine adjustment hand wheel (7) is arranged on the other side wall plate (13) of the machine body (9); the large end of the limiting plate (6) is arranged at the upper end of the sliding block (10), and the other end of the limiting plate (6) is inserted into the upper end of the adjusting nut (2); when the stroke (closing height) needs to be adjusted, the worm (4) can be rotated to drive the worm wheel (5) to rotate, the worm wheel (5) drives the adjusting screw rod (1) to rotate, and the adjusting nut (2) is limited by the guide key (12) and can only move up and down along the chute of the guide plate (11), so that the distance between the adjusting nut (2) and the limiting plate (6) is changed, and the purpose of adjusting the stroke (closing height) is achieved, as shown in fig. 3 and 4; when the stroke (the sealing height) is adjusted, the motor (8) or the hand wheel (7) is rotated to drive the adjusting nut (2) to move up and down to the required stroke (the sealing height) according to the process requirements of the product. Due to the effect of the design, the adjustment of the stroke (closing height) of the sliding block becomes simple, convenient and accurate, the time is saved, and the repeated positioning precision from the sliding block (10) to the bottom dead center is greatly improved.
