[0002] In the process of building construction, wooden squares are usually used as the keel of the formwork system. Since the strength of wooden squares is relatively low, in order to improve the strength, a common method is to wrap a layer of iron sheet on the outside of the wooden squares. The existing technology of wrapping iron sheet on wooden squares is to use special equipment to make iron sheet square frames of corresponding specifications, and then manually put the wooden squares into the iron sheet square frames. In the process of realizing the present invention, the inventor found that the existing technology has the following disadvantages:

[0074] In the sixth step, after the wood conveying mechanism places the wood 34 on the first mold 1, the first cylinder 23 works, the telescopic rod of the first cylinder 23 drives the push rod 24 to move, and the push rod 24 pushes the wood 34 to move toward the wood pressing groove 17.

[0075] In the seventh step, when the second pressure sensor 38 on the limiting rod 21 detects the pressure of the wooden block 34 on the limiting surface, the first cylinder 23 is reset, and the telescopic rod of the first cylinder 23 drives the push rod 24 to return.

[0076] Step 7: After the first air cylinder 23 is reset, the second hydraulic cylinder 5 starts to work, and the second hydraulic cylinder 5 controls the second pressing head 8 to press the wooden block 34 vertically downward.

[0077] In the eighth step, after the wood 34 is completely pressed into the wood pressing groove 17, the second hydraulic cylinder 5 is reset, and the second hydraulic cylinder 5 drives the second pressing head 8 to return.
