I. Several reasons for the tailstock jumping on a spinning machine and how to solve them?
The tailstock of a spinning machine is prone to jumping. Below are several reasons for this and their corresponding solutions.
1. Operational error: the cutter wheel collides with the tailstock shaft, causing deformation of the tailstock shaft.
2. Insufficient precision in the matching of the tailstock and the tailstock shaft.
3. Wear and tear of the tailstock shaft bearing; abnormal noises occur when the tailstock shaft rotates.
4. Poor assembly precision of the main shaft mold and flange, causing tailstock jumping.
II. What is the impact of tailstock jumping on spin-formed products?
Tailstock jumping on a spinning machine will have a certain impact on spin forming, mainly including the following factors:
1. Stainless steel, due to its poor material ductility and high stress, may fracture at the root due to uneven stress when the tailstock jumps.
2. Aluminum has low hardness, and the spinning process may scratch the bottom of the spin-formed product due to tailstock jumping.
3. Tailstock jumping can reduce the contact area between the sheet and the tailstock, and the spinning force can cause the sheet to move.
4. Tailstock jumping will affect the dimensional accuracy of the finished product, reducing the diameter accuracy of the bottom of the product.
III. Main causes of jamming during the process of large-scale strong spinning of the spinning machine's main shaft
1. The spinning mold is not weight-reduced; the mold is too heavy.
2. The main shaft motor belt is old and loose; adjust the preload.
