During feeding and discharging, the rolling wheels upwards stretch out of the lower die tool arranged on the lower die base plate in a bearing mode through the roller holes, and under driving of the rolling wheel driving mechanism, rolling of the rolling wheels drives the lower die tool to move for feeding and discharging.

Description

Technical Field

[0001] The utility model relates to a press with lower die belt conveying. Background Art

[0002] In the production of some sheets, several sheets need to be pressed together by a press. When the sheets are pressed together, they are placed in a mold tooling. In the subsequent production process, the mold tooling is required to further process the pressed sheets. At this time, the press requires the mold tooling and the product to be pressed up and down synchronously. On the other hand, in this case, the mold tooling and the product are not suitable for transfer using a suction cup manipulator. Summary of the invention

[0003] The problem to be solved by the utility model is the automation problem of loading and unloading when the mold tooling and the product are not suitable for loading and unloading by a suction cup manipulator.

DETAILED DESCRIPTION

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] Figure 1An example of a press with a lower die and a lifting conveyor is provided. The press comprises a frame 1, a lower die base plate 2 and an upper die mechanism 3 arranged on the frame 1. The frame 1 comprises a base 11, four vertical columns 12 arranged at the four corners of the base 11, and a top frame 13 arranged at the top of the four columns 12. The lower die base plate 2 is arranged on the base 11. The upper die mechanism 3 comprises an upper die frame 31 and a pressing power mechanism 32. In this embodiment, the pressing power mechanism 32 is composed of two cylinders arranged on the top frame 13. The upper die frame 31 is located directly above the lower die base plate 2, and a lifting guide mechanism is arranged between the upper die frame 31 and the four columns 12, which is connected to the pressing power mechanism 32. The upper die frame 31 can be lifted and lowered under the drive of the pressing power mechanism 32, and the lifting driven by the pressing power mechanism 32 realizes the downward pressing of the lower die base plate 2 by the upper die frame 31, thereby completing the pressing operation of the press. When the press of this embodiment is pressing, the material is placed on the lower die tooling. The upper die frame 31 is provided with an upper die that cooperates with the lower die tooling. When pressing materials, the lower die tooling is placed on the lower die base plate 2. In order to facilitate the lower and upper movement of the lower die tooling on the press, in this embodiment, the press is also equipped with a jacking and conveying mechanism 4. The jacking and conveying mechanism 4 is used for loading and unloading materials on the press.

[0018] Reference Figure 2 , Figure 3 and Figure 4 The lifting and conveying mechanism 4 includes a lifting frame 41, rollers 42, a lifting power mechanism 43 and a roller driving mechanism 45. The lifting frame 41 is arranged on the base 11 through the lifting power mechanism 43 and is located below the lower die base plate 2, so that the lifting frame 41 can be raised and lowered under the drive of the lifting power mechanism 43. The rollers 43 and the roller driving mechanism 45 are arranged on the lifting frame 41, so that the rollers 43 and the roller driving mechanism 45 can be raised and lowered synchronously with the lifting frame 41. The lower die base plate 2 is provided with a roller hole 21 adapted to the roller 43. When the lifting frame 41 is lifted or lowered under the drive of the lifting power mechanism 43, the roller 43 can extend upward or retract downward through the roller hole 21 provided on the lower die base plate 2. When the roller 43 extends upward through the roller hole 21, it can carry the lower die tooling set on the lower die base plate 2; when the roller 43 retracts downward, the weight of the lower die tooling on the lower die base plate 2 is borne by the lower die base plate 2, so that when the upper die frame 31 is pressed downward, the pressure of the upper die frame 31 on the lower die tooling is borne by the lower die base plate 2. The roller 43 is connected to the roller drive mechanism 45. When the roller 43 extends upward through the roller hole 21 and carries the lower die tooling set on the lower die base plate 2, the roller 43 can roll under the drive of the roller drive mechanism 45, thereby driving the lower die tooling to move, thereby realizing the loading and unloading of the lower die tooling on the press.

[0019] In this embodiment, the lifting power mechanism 43 is composed of four cylinders arranged at the four corners of the lifting frame 41. Those skilled in the art understand that in another embodiment, the lifting power mechanism 43 can also be implemented in other ways, such as a gear rack connected to a motor.

[0020] In addition, in this embodiment, in order to achieve smooth horizontal lifting of the lifting frame 41, the lifting frame 41 is guided by four guide column and guide sleeve mechanisms 44 at the four corners.

[0021] Further, in this embodiment, the roller 41 is divided into two groups: a first roller group 4201 and a second roller group 4202. The first roller group 4201 and the second roller group 4202 each have a plurality of rollers 42 arranged in a straight line. And these rollers 42 are all located at the same level. Correspondingly, the roller holes 21 provided on the lower die base plate 2 are also divided into two groups, and each group of roller holes has a plurality of roller holes 21 arranged in a straight line. Correspondingly, the roller drive mechanism 45 includes a motor 451, a synchronous shaft 452, a chain 453 and a sprocket 454. The first roller group 4201 and the second roller group 4202 are connected to the chain 453 through the sprocket 454, and are connected to the synchronous shaft 452 through the chain 453 and the sprocket 454. The synchronous shaft 452 is connected to the motor 451. Thus, the motor 451 can drive the roller 42 to rotate through the synchronous shaft 452, the chain 453 and the sprocket 454.

[0022] Those skilled in the art understand that, in order to make the rollers 41 better support the lower die tooling, in another optional embodiment, the rollers 41 can also be divided into three groups, four groups or five groups, each group has a number of rollers arranged in a straight line. Correspondingly, the roller holes 21 on the lower die base plate 2 are also divided into a corresponding number of groups, and each group of roller holes has a number of roller holes 21 arranged in a straight line.
