They not only enhance the structural strength of the equipment but also provide reliable support points for other components. Balance rods 106 are fixedly connected to the front sides of the movable tables 105.

It is necessary to select a suitable mold 003 according to the shape and size of the workpiece and ensure that the mold 003 is firmly fixed to prevent displacement during the working process. When the lifting cylinder 204 is started, through the transmission of the chain 206 and the follower sprocket 207, the long fence 203 rises along the guide groove 205. The function of the lifting fence 002 is to provide safety protection during the processing to prevent the operator from contacting the dangerous area and ensure that no accidents occur during the working process.
