DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the embodiment, Figure 1 and 2 A hydraulic shearing machine for metal product production is provided, comprising a base 1, the top of the base 1 is fixedly connected with four support arms 2, the four support arms 2 are connected through a mounting seat 3, the inner side of the mounting seat 3 is fixedly connected with a hydraulic cylinder 4, the output end of the hydraulic cylinder 4 is fixedly connected with an ear block 5, the inner side of the ear block 5 is fixedly connected with a fixed shaft 6, the outer side of the fixed shaft 6 is fixedly connected with an upper tool platform 7, the bottom end of the upper tool platform 7 is fixedly connected with an upper tool holder 8, the front end of the upper tool holder 8 is detachably connected with three upper cutting blades 10, the bottom surfaces of the three upper cutting blades 10 are all inclined at 10° with the top surface of the base 1, and the upper The left and right ends of the cutting blade 10 are in close contact with the upper cutting blade 10 on the left and the upper cutting blade 10 on the right, respectively. Two guide assemblies 11 are arranged between the mounting seat 3 and the base 1. The two guide assemblies 11 are fixedly connected to the left and right ends of the upper tool platform 7, respectively. The top of the base 1 is fixedly connected with a lower tool holder 12, and the rear end of the lower tool holder 12 is detachably connected with three lower cutting blades 13. The bottom surfaces of the three lower cutting blades 13 are parallel to the top surface of the base 1, and the left and right ends of the lower cutting blade 13 in the middle are in close contact with the lower cutting blade 13 on the left and the lower cutting blade 13 on the right, respectively.

[0020] Through the above arrangement, the metal product is placed on the lower tool holder 12, and the hydraulic cylinder 4 is started. The output end of the hydraulic cylinder 4 moves downward, so that the ear block 5, the fixed shaft 6, the upper tool table 7, the upper tool holder 8 and the three upper cutting blades 10 move downward. The upper cutting blade 10 on the right first contacts the metal product, and then cooperates with the lower cutting blade 13 on the right to cut the metal product during the continuous downward movement. Then, the middle upper cutting blade 10 cooperates with the middle lower cutting blade 13 to continue cutting. Finally, the upper cutting blade 10 on the left cooperates with the lower cutting blade 13 on the left to complete the last part of cutting, thereby completing the cutting work of the metal product. The three upper cutting blades 1 The bottom surfaces of the base 1 and the bottom surfaces of the base 1 are inclined at 10° with the top surface of the base 1, so that the three upper cutting blades 10 cooperate with the three lower cutting blades 13 to cut the metal products in turn. Compared with the three upper cutting blades 10 cutting the metal products at the same time, the resistance is smaller, making the metal products easier to cut. When one of the three upper cutting blades 10 and the lower cutting blade 13 is worn or curled, it can be disassembled and replaced. Since the number of the upper cutting blades 10 and the lower cutting blade 13 is three instead of one, one of the worn or curled blades can be replaced, which is more cost-effective than replacing an entire blade, and the replacement process is simpler.

[0021] Reference Figure 1 and 2, wherein the guide assembly 11 comprises a guide column 111, the guide column 111 is fixedly connected between the mounting seat 3 and the base 1, the outer side of the guide column 111 is fixedly connected to a limiting sleeve 112, the outer side of the guide column 111 is slidably connected to a sliding sleeve 113, and the sliding sleeve 113 is fixedly connected to the upper tool platform 7;

[0022] Through the above-mentioned structural setting, the sliding sleeve 113 slides upward or downward along the outer side of the guide column 111 to play a guiding role, and the limiting sleeve 112 can resist the sliding sleeve 113 to limit the sliding sleeve 113 from further moving downward, thereby preventing the upper tool table 7, the upper tool holder 8 and the three upper cutting blades 10 from being displaced too much, causing the upper cutting blade 10 to touch the base 1 and cause the upper cutting blade 10 to be damaged.

[0023] Reference Figure 1 and 2 , wherein the front end of the upper tool holder 8 and the rear end of the lower tool holder 12 are both provided with a plurality of bolts 9, the outer sides of the plurality of bolts 9 are all threadedly connected with nuts 14, and the plurality of nuts 14 are respectively in close contact with the rear ends of the three upper cutting blades 10 and the front ends of the three lower cutting blades 13;

[0024] Through the above-mentioned structural setting, when the three upper cutting blades 10 and the three lower cutting blades 13 are worn or curled, the corresponding bolts 9 and nuts 14 can be screwed, removed and replaced with corresponding parts. The disassembly and assembly process is simple and convenient, which is beneficial to the actual production of the enterprise.
