Description

Nine-link mechanical press

technical field

The utility model relates to metal forming processing equipment without cutting, in particular to a mechanical press.

Background technique

In the field of metal forming processing, especially in sheet metal stamping, forming, and sheet drawing processes, mechanical presses are one of the main processing equipment. However, the traditional mechanical press cannot effectively control the stamping forming speed, and it is difficult to avoid the springback phenomenon of stamping parts. In recent years, servo presses have appeared, such as connecting rod presses from Amino Corporation in Japan, Komatsu HF series presses in Japan, double toggle presses from Ohio State University in the United States, and presses from Qiqihar Second Machine Tool Group. The speed characteristics and dynamic performance of the slider are improved, and a variety of different pressure working curves are obtained, but the manufacturing cost is relatively high.

Contents of the invention

The purpose of the utility model is to solve the shortcomings of existing metal forming presses such as poor forming quality and difficulty in suppressing the springback of stamping parts. The utility model provides a nine-link mechanical press, which is driven by a fixed-speed motor , lower stamping speed and longer stop time at the bottom dead center can be obtained to meet the requirements of high-quality stamping operations.

The technical scheme of the utility model is: a nine-link mechanical press, the press includes a first gear, a second gear, a first connecting rod, a second connecting rod, three auxiliary components, a swing rod, and a frame , the hammer connecting rod and the hammer, the first gear and the second gear are respectively connected to the frame through the rotating pair, the first gear and the second gear are meshed with each other, the first connecting rod and the first gear are connected through the rotating pair, The second connecting rod is connected with the second gear through a rotating pair, the first connecting rod, the second connecting rod and the three secondary components are connected at the same place through a rotating pair, and the three secondary components are respectively connected with the pendulum and the hammer through a rotating pair The rods are connected, the swing rod is connected with the frame through a rotary pair, the end of the hammer connecting rod is connected with the punch through a rotary pair, and the punch is in the fixed guide rail.

The beneficial effects of the utility model are: lower stamping speed and longer stop time at the bottom dead center can be obtained, which solves the problems of poor stamping quality and springback of stamping parts in traditional mechanical presses; at the same time, the press has great advantages Good force transmission characteristics.

Fig. 1 is the structural representation of the specific embodiment of the utility model.

Detailed ways

The specific embodiment of the utility model shown in Figure 1 is a nine-link mechanical press, which includes a first gear 1, a second gear 2, a first connecting rod 3, and a second connecting rod 4 , three sub-components 5, pendulum 7, frame 6, hammer connecting rod 8 and hammer 9, the first gear 1 and the second gear 2 are connected with the frame 6 through the rotating pair respectively, the first gear 1 and the second The two gears 2 mesh with each other, the first connecting rod 3 is connected with the first gear 1 through a rotating pair, the second connecting rod 4 is connected with the second gear 2 through a rotating pair, the first connecting rod 3, the second connecting rod 4 and The three sub-components 5 are connected at the same place through the rotating pair, and the three sub-components 5 are respectively connected with the swing rod 7 and the hammer connecting rod 8 through the rotating pair, the swing rod 7 is connected with the frame 6 through the rotating pair, and the hammer is connected with each other. The end of the rod 8 is connected with the hammer 9 through the rotary joint, and the hammer 9 is in the fixed guide rail.

When working, the first gear 1 rotates under the drive of the fixed-speed motor, and the second gear 2 rotates under the drive of the first gear 1. Under the action of the first gear 1 and the second gear 2, the second gear The first connecting rod 3, the second connecting rod 4 and the three sub-members 5 make complex plane movements respectively, the pendulum 7 swings back and forth around the frame 6, and the hammer connecting rod 8 makes a plane movement. During this process, the hammer 9 Also start to move under the effect of ram connecting rod 8, because be subjected to the horizontal direction limit of guide rail, and ram connecting rod 8 and ram 9 are mutually hinged again, so ram 9 can only punch up and down in the guide rail.
