Preferably, the first driving mechanism is an oil cylinder.

Preferably, the second driving mechanism is an air cylinder.

Preferably, the third driving mechanism is an oil cylinder.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions:

Put the product into the bending punch and position it well; then, the third driving mechanism drives the upper platen to move downward, so that the upper platen presses the product; then, the first driving mechanism pushes the bending die forward and approaches the bending Then, the pressure is maintained for 2-3 seconds; then, the third driving mechanism drives the upper platen to reset upwards, and under the action of the second driving mechanism, the bending punch is driven to push the product up. Stripping; finally, take out the product to complete a seamless bending. The mold has the advantages of simple structure, convenient operation and low cost.

In order to illustrate the structural features and functions of the utility model more clearly, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

detailed description

Please refer to Fig. 1 and shown in Fig. 2, it has shown the concrete structure of the preferred embodiment of the present utility model, comprises lower seat plate 11, upper seat plate 12, lower backing plate 13, bending die 14, bending The punch 15 , the upper platen 16 , the first driving mechanism 17 , the second driving mechanism 18 and the third driving mechanism 19 .

The upper seat plate 12 is suspended and installed directly above the lower seat plate 11 through the contour column 21, and the lower base plate 13 is arranged on the surface of the lower seat plate 11; in this embodiment, the lower seat plate 11 is a square frame plate , there are multiple equal-height columns 21 .

The bending die 14 and the bending punch 15 can be arranged on the lower backing plate 13 to move back and forth left and right, and the bending die 14 and the bending punch 15 cooperate with each other and face each other; the upper pressing plate 16 can move up and down. It is arranged directly above the bending die 14 and the bending punch 15 , and the upper pressing plate 16 is located below the upper seat plate 12 .

The first driving mechanism 17 and the second driving mechanism 18 are both arranged on the lower seat plate 11. The first driving mechanism 17 drives the bending die 14 to move back and forth and away from or close to the bending punch 15.
