Description

Technical Field

[0001] The utility model relates to the technical field of reinforced steel positioning tools, in particular to a PVC profile reinforced steel positioning tool. Background Art

[0002] The installation and fixation of reinforced steel or other PVC window reinforced linings is an important part of PVC window production, and is also related to the overall strength and stability of PVC windows. At present, large-scale PVC window manufacturers generally use fully automatic PVC profile cutting, processing, and fully automatic PVC profile and reinforced steel fastening production lines. However, in the step of inserting reinforced steel into PVC profiles, due to the difficulty of material identification and machinery, it is often done manually. During the production process, the operator is generally located on one side of the material conveying equipment, and the conveyor belt transports the PVC profile and reinforced steel from both sides to the front of the operator. After the operator identifies the material and checks the size, he manually inserts the reinforced steel into the PVC profile, and then the conveyor belt transports the combined profile to the next process.

[0003] According to the relevant provisions in the national standards, there are strict requirements on the distance range between the reinforced steel and the end of the PVC profile after penetration. At the same time, if the position of the reinforced steel in the PVC profile is not centered, it will cause uneven force on the corners of the profile after the entire frame is welded, affecting the overall strength and stability of the PVC window. In the actual production process, there are also cases where the reinforced steel is penetrated too deep, causing the steel to exceed the end of the PVC profile. Utility Model Content
