Description

Technical Field

[0001] The utility model belongs to the technical field of shopping cart production, in particular to a shopping cart frame bending machine. Background Art

[0002] A shopping cart is a device used to temporarily store the selected goods when we shop in a supermarket. It is usually a trolley, which is usually composed of a basket, a base frame, armrests and wheels. Some shopping carts can also be used to carry children. Using a shopping cart when shopping in a supermarket allows you to easily select goods, and you can settle the bill at the end of the purchase, which provides great convenience for customers.

[0003] In the prior art, when producing shopping cart baskets, the metal bars need to be bent and then welded. During long-term use and observation, it is found that when the current metal bar bending machine bends the metal bars, if you want to change the curvature of the turn, you need to replace the bending seats of different sizes. When replacing the bending seats, auxiliary tools are needed to disassemble and assemble the bending seats, which makes the process of processing metal bars with different curvatures more cumbersome.

[0004] To this end, the utility model provides a shopping cart frame bending machine. Utility Model Content
