Steel backing plate wiredrawing equipment and method

A steel backing plate wiredrawing method, comprising the following specific steps:

• step S1:
• superposing and stacking two layers of steel plates on a support plate (6), and aligning edges;
• step S2:
• using a numerical control cutting machine (11) to simultaneously cut, according to a numerical control programming language, the two layers of steel plates to obtain a steel backing plate member;
• and by decreasing the power of the cutting machine and a cutting depth, further cutting the top-layer steel plate only to obtain a reinforcing rib subassembly (81) on the steel backing plate;
• step S3:
• using a vacuum chuck at a bottom end of a vacuum cylinder (13) to pull in the reinforcing rib subassembly (81);
• using a glue dispenser (19) to perform a glue dispensing operation to dispense a structural adhesive on an upper end surface of the bottom-layer steel plate (71);
• then placing the reinforcing rib subassembly (81) on the structural adhesive;
• step S4:
• after the glue dispensing operation is terminated, since the whole glue dispensing operation does not spend much time, and the structural adhesive on the bottom-layer steel plate (71) is not completely cured yet, at the time, using a pressure roller (16) to roll the top-layer steel plate so that the bottom-layer steel plate (71) is combined with the reinforcing rib subassembly (81) on the top layer more closely;
• step S5:
• after the cutting of the reinforcing rib subassembly (81) is completed, since a remaining part of the top-layer steel plate becomes a waste, using a hoisting device to remove the waste;
• step S6:
• using a spot welder (15) to perform a spot welding operation on the bottom-layer steel plate (71) and the reinforcing rib subassembly (81) on the top layer:
• performing spot welding on inner edges of connection surfaces of the bottom-layer steel plate and the reinforcing rib subassembly;
• and
• step S7:
• finally, taking out the prepared steel backing plate structure.
