Detailed Description

The principles and features of the present invention are described below in conjunction with the accompanying fig. 1-5, which are provided by way of example only to illustrate the present invention and not to limit the scope of the present invention.

A tubular pressure forming machine comprises a bottom plate 1, three lower dies 2, an upper die 3, a frame 4, a first driving mechanism 5 and a second driving mechanism 6. The bottom plate 1 is provided with a guide rail, and the three lower dies 2 are mutually connected and fixed and are respectively connected with the guide rail in a sliding manner. The first driving mechanism 5 is fixedly connected with one of the lower dies 2 and used for driving the lower die 2 to slide. The upper die 3 is fixedly connected with the rack 4, and the second driving mechanism 6 is fixedly connected with the upper die 3 and used for driving the upper die 3 to slide. The upper die 3 can slide downwards to be matched with one lower die 2 to press and form the workpiece. The three lower dies 2 form three stations, when one lower die 2 and the upper die 3 are opposite up and down to carry out pressing operation, the rest two stations can load workpieces at the same time, so that the whole equipment does not need to be stopped, and the working efficiency is improved.

The top of frame 4 is provided with a protruding fixed block 7 that forms, go up fixed block 7 and set up in the top of last mould 3, go up mould 3 fixedly connected with guide bar 8, guide bar 8 passes go up fixed block 7 and frame 4 formation sliding connection. The second driving mechanism 6 is a cylinder, the cylinder is fixedly connected to the top of the frame 4, and the telescopic end of the cylinder penetrates through the upper fixed block 7 to be fixedly connected with the upper die 3, so that the upper die 3 is driven to slide up and down. A spring 9 is arranged between the upper fixed block 7 and the lower die 2, and the spring 9 and the guide rod 8 are coaxially sleeved; the spring 9 has a buffering function and a limiting function, and prevents the upper fixed block 7 from colliding with the upper die 3.

In order to facilitate taking out the workpiece from the lower die 2, a third driving mechanism 10 and a supporting leg 11 are added; the third driving mechanism 10 and the leg 11 are provided between the lower die 2 and the upper die 3. The third driving mechanism 10 is a cylinder, the cylinder is fixedly connected with the frame 4, the telescopic end of the cylinder is connected with the support leg 11, and two sides of the support leg 11 are bent towards the same side, so that the whole support leg 11 is U-shaped. Wherein, the bending parts at the two sides of the support leg 11 are triangular, and the tip end faces the lower die 2. The lower die 2 is provided with a guide groove 12. The third driving mechanism 10 can drive the legs 11 to move the bent portions thereof into the guide grooves 12. After the workpiece is machined, the lower die 2 and the upper die 3 are separated from each other, the third driving mechanism 10 is started to enable the support legs 11 to move towards the guide grooves 12, the workpiece is ejected out, manual operation is avoided, and production efficiency is further improved.
