Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Example 1: as shown in the attached drawings 1-8, the manual thin steel plate bending press comprises a base 10 and a handle 1, wherein the base 10 is connected with four guide posts 9 and two supports 11, the guide posts 9 are provided with a first sliding sleeve 6 and a second sliding sleeve 4, the first sliding sleeve 6 is connected with two symmetrical vertical plates 13, the vertical plates 13 are connected with a flat plate 17, the second sliding sleeve 4 is connected with a fixed frame 16, the fixed frame 16 is provided with a threaded sleeve 3, a screw rod 2 penetrates through the threaded sleeve 3 to be connected to the flat plate 17, the handle 1 is connected to the top end of the screw rod 2, the vertical plates 13 are provided with a bearing seat 5 and connected with a bending shaft 14 through a bearing, a bearing shaft 8 is arranged between the supports 11, and a plurality of bearings 7 are.

Further, the support 11 is vertically and symmetrically arranged between the guide posts 9, symmetrical grooves 20 are formed in the support 11, and two ends of the bearing shaft 8 are located in the grooves 20. The grooves 20 are symmetrically arranged in three pairs, have different heights and are of arc structures, so that the requirements of different bending sizes can be met.

Further, the bending shaft 14 is horizontally arranged above the bearing shaft 8 and parallel to the axis of the bearing shaft 8. The press bending shaft 14 and the two bearing shafts 8 form three line contact surfaces with a thin steel plate to be bent, the thin steel plate to be bent horizontally penetrates between the press bending shaft 14 and the bearing shafts 8, the bearing shafts 8 are fixed in the vertical direction, the flat plate 17 is driven to move downwards by shaking the handle 1, at the moment, the press bending shaft 14 can move downwards slowly, the press bending operation is performed on the thin steel plate, the bearings are arranged at the two ends of the press bending shaft 14, the press bending shaft 14 can roll instead of slide in the press bending process, and the steel plate cannot be damaged by pulling.

Furthermore, the bearing 7 adopts a ball bearing, which is an innovative point, when the steel plate is bent downwards, the friction and the contact abrasion of the steel plate can be reduced through the rolling characteristic of the ball bearing, and the shape integrity of the steel plate is kept.
