Description

Technical Field

[0001] The present application relates to the technical field of silicon steel sheet production and processing, and in particular to a silicon steel sheet laser cutting device. Background Art

[0002] Laser cutting machines have high cutting efficiency, small thermal deformation, and high precision when processing workpieces, and are particularly advantageous in the sheet metal thin plate processing industry. However, when laser cutting is applied to the processing of motor stator and rotor products with very thin silicon steel sheets (generally less than 0.5 mm), the problem of poor rigidity and easy deformation caused by the thin thickness of the silicon steel sheets will be encountered, making it impossible to achieve high precision in laser cutting. The fixture structure currently used in existing laser cutting machines cannot completely solve the problems of poor rigidity and easy deformation of silicon steel sheets, making it difficult for laser cutting to meet the high requirements of high precision and consistency tolerance of the size and position of stator and rotor products. This greatly limits the advantages of laser cutting and the application of laser cutting of stator and rotor products in the motor industry.

[0003] The existing silicon steel sheet blanks are mainly placed on a flat table during processing, and the edges of the silicon steel sheet blanks are clamped by a fixture, and then the silicon steel sheet blanks are laser processed to finally form motor silicon steel sheet products. However, the thickness of the processed silicon steel sheet blanks is only 0.2~0.5 mm, so the following problems will occur: (1) Processing accuracy Silicon steel sheet blanks are relatively thin, and conventional fixtures cannot effectively clamp them. When the silicon steel sheet blanks are cut, the high-speed gas ejected from the laser head will cause the silicon steel sheet blanks to shake and deform, seriously affecting the accuracy and dimensional consistency of the processed products, making it impossible to process high-precision products.

[0004] (2) Product burrs Since the silicon steel sheet blank is placed on the platform, during laser cutting, the laser discharge easily forms thick burr defects at the contact point between the bottom surface of the processed product and the table top, resulting in a high product scrap rate.

[0052] The implementation principle of Example 1 is as follows: when different styles of silicon steel sheet products need to be processed, the corresponding placement panel 3 is placed on the upper end of the mounting seat 411, and the sliding seat 43 is pushed to slide, so that the two first baffles 4122 abut against the two sides of the outer frame plate 31, and the knob 442 is turned to rotate the threaded rod 441, so that the threaded rod 441 abuts against the outer wall of the guide rod 42, thereby achieving relative fixation of the sliding seat 43 and the guide rod 42. The piston rod of the first driving cylinder 413 extends, driving the first connecting plate 4123 to move downward, driving the first baffle 4122 to move downward, and driving the first abutting plate 4121 to move downward to abut against the surface of one side of the outer frame plate 31 away from the mounting seat 411, thereby achieving installation of the placement panel 3.

[0053] The silicon steel sheet blank is placed above the placement panel 3, so that the end of the silicon steel sheet blank away from the cabinet door 13 abuts the second baffle 352. After the silicon steel sheet blank is flattened, the piston rod of the second driving cylinder 34 extends, driving the second connecting plate 353 to move downward, driving the second baffle 352 to move downward, and driving the second abutting plate 351 to move downward to abut against the side surface of the silicon steel sheet blank away from the outer frame plate 31. The gas in the connecting channel 3312 enters the second driving cylinder 34 through the first air channel 3314 and the external pipeline, so that the air pressure at the outer air channel 3315 and the inner air channel 3313 is reduced, so that the silicon steel sheet blank is pressed against the placement panel 3 under the action of atmospheric pressure, and the silicon steel sheet blank and the placement panel 3 are relatively fixed.

[0054] The second driving cylinder 34 presses the gas into the limiting groove 123 through the pipeline and the second air channel 113, pushing the piston block 153 to move upward, so that the limiting block 151 extends out of the limiting groove 123. When the cabinet door 13 is closed, the cabinet door 13 abuts against the second chamfer 1511, pushing the limiting block 151 to overcome the elastic force of the second reset member 152 and embed into the limiting groove 123. When the positioning groove 131 and the limiting groove 123 are facing each other, the limiting block 151 is embedded in the positioning groove 131 under the action of the elastic force of the second reset member 152, thereby realizing the relative fixation of the cabinet door 13 and the shell 12.

[0055] After the processing is completed, the piston rod of the second driving cylinder 34 contracts, driving the second connecting plate 353 to move upward, driving the second baffle 352 to move upward, and driving the second abutment plate 351 to move upward and away from the silicon steel sheet blank. The air pressure in the connecting channel 3312 returns to normal atmospheric pressure, and the air pressure in the limit groove 123 drops. The piston block 153 moves downward under the action of gravity, driving the limit block 151 to disengage from the positioning groove 131, so that the lock of the cabinet door 13 and the shell 12 is released.
