[0018] Figure 2 for Figure 1 Left view of . DETAILED DESCRIPTION Example
[0019] like Figure 1 and Figure 2As shown, a molybdenum wire automatic tensioning device includes a wire cutting machine wall 180, a guide rail 101 arranged in the upper and lower directions is installed in the middle of the wire cutting machine wall 180, fixed wire wheels 114 are installed on the left and right sides of the wire cutting machine wall 180, an upper sliding block 103 is installed on the guide rail 101, and a lower sliding block 102 is installed on the guide rail 101. The lower sliding block 102 is located below the upper sliding block 103, and the upper sliding block 103 is connected to the upper sliding block 103. The tensioning seat 104 is connected to the padding block 105. The tensioning seat 104 and the padding block 105 are integrally formed. A guide column 106 is provided on the padding block 105. A guide wheel seat 107 is provided on the guide column 106. A tensioning guide wheel 113 is installed on the guide wheel seat 107. A linear bearing 109 is provided between the guide column 106 and the guide wheel seat 107. The linear bearing 109 is slidably fitted on the guide column 106. The guide wheel seat 107 is fixed to the linear bearing 109, and the top of the guide column 106 is provided with a guide column retaining ring 112. The guide column 106 is provided with a first spring 108 at the guide column position between the guide wheel seat 107 and the guide column retaining ring 112. The two ends of the first spring 108 are in contact with the linear bearing 109 and the guide column retaining ring 112 respectively; the guide column 106 is provided with a second spring 11 1. The guide column 106, the guide column retaining ring 112, the first spring 108, the linear bearing 109 and the second spring 111 are all in two groups, and are arranged symmetrically with the guide wheel seat 107 as the center; the lower sliding block 102 is connected to the top raising block 110, the bottom of the top raising block 110 is connected to the electric screw, and the electric screw is installed on the wire cutting machine wall 180; the top of the top raising block 110 can be pushed and connected, and can be withdrawn and separated from the tensioning seat 104.
[0020] Working principle: The electric screw drives the top pad 110 and the lower sliding block 102 to move upward, and the top pad 110 pushes and contacts the tensioning seat 104, pushing the upper sliding block 103, the pad 105, the guide wheel seat 107 and the tensioning guide wheel 113 to move upward until the bottom of the tensioning guide wheel 113 is higher than the top of the fixed wire wheel 114 and stops. The wire cutting wire passes through the top of the fixed wire wheels 114 on the left and right sides, and the wire cutting wire in the middle part of the fixed wire wheels 114 on both sides is mounted from the bottom of the tensioning guide wheel 113. The wire cutting wire moves forward to complete the threading, and the electric screw drives the top pad 110 and the lower sliding block 102 to move downward to return to the initial lowest position. The top of the top pad 110 retreats and is always separated from the tensioning seat 104. At this time, the upper sliding block 103, the tensioning seat 104, the pad 105, the guide wheel seat 107 and the tensioning guide wheel 113 move downward due to gravity. The tensioning guide wheel 113 forms a constant gravity ballast on the wire cutting wire in the middle part of the fixed wire wheels 114 on both sides, thereby realizing the tensioning operation of the wire cutting wire.
