Detailed Description

The invention will now be described in detail with reference to the accompanying drawings and specific examples.

As shown in fig. 1-12, a side bending structure for pressing materials comprises an upper die holder 1, an upper base plate 2, an upper clamping plate 3, a pressing plate 5 and a lower die holder 13 are sequentially arranged below the upper die holder 1, a lower base plate 12, a lower die plate 11, a leaning block 7, a slide block fixing seat 9 and a processing mechanism for pressing and fixing a product 22 for bending are arranged above the lower die holder 13, the processing mechanism comprises a cutting assembly fixed on the upper die holder 1 and a pressing bending assembly arranged in the slide block fixing seat 9, a stop block 8 for blocking a downward running path of the limiting pressing bending assembly is arranged between the slide block fixing seat 9 and the pressing bending assembly, the cutting assembly comprises two first cutting blades 20 and second cutting blades 4 with different lengths, the pressing bending assembly comprises a side pressing block 18 and a side bending block 6 corresponding to the first cutting blade 20 and the second cutting blade 4, a lower die forming block 15 for pressing and bending a product 22 in a matched manner with the side bending block, a spring for completing the processing is arranged on the pressing assembly, a first cutting blade fixing seat 9 and the stop block is arranged between the pressing bending assembly and the pressing bending assembly, the stop block is provided with a first cutting blade 20 and a second cutting blade 4 for preventing the first cutting blade from being bent at the upper end and the lower cutting assembly from being bent by a return end of the upper die holder, the stop block is provided with a second cutting block 4 corresponding to the upper die seat, and a return spring is provided with a return end of the upper cutting block 4 is provided with a stop block for preventing the upper die seat for bending material from being bent, a platen insert 17 is provided under the platen 5 for assisting the platen 5 in compressing the product 22.
