Description

Technical Field

[0001] The invention relates to a mechanical device, in particular to a transformer silicon steel sheet continuous punching and loading device. Background Art

[0002] The amount of silicon contained in silicon steel sheets is usually between 0.8% and 4.8%. Because of its high magnetic conductivity, low iron loss and sufficient mechanical strength, it can reduce hysteresis loss and eddy current loss when working under AC state, thereby improving the efficiency of the transformer and reducing the degree of heat generation. Silicon steel sheets usually appear in the form of stacked sheets in transformers. This structure helps to reduce eddy current losses and increase the filling factor of the core. In the prior art, silicon steel sheets are mostly stamped by molds. The formed silicon steel sheets are collected and stacked by operators in the next stacking process. Since the stamping edge is easily affected by the mold and the end face is easily deformed, the silicon steel sheets need to be stacked in sequence according to the stamping surface before they can be compacted. However, when stacking, operators tend to mix the front and back sides of the silicon steel sheets, resulting in the silicon steel sheets not being able to fit completely, affecting the performance of the finished transformer. Therefore, the inventors adopted a new stamping scheme, such as Fig.12 As shown, the raw material is first punched out with a punching groove 3003 on a punching machine, and at least two connecting ribs 3004 are retained, so that the silicon steel sheet 3002 is connected to the substrate 3001, and then a punching opening is punched out on the connecting rib 3004 to obtain a silicon steel sheet frame. The operator can easily punch out the punching opening with a simple fixture, so as to stack and load the sheets, so as to ensure that the silicon steel sheets are not mixed with the front and back sides. However, due to the large number of silicon steel sheets required, the efficiency of manual punching and stacking is reduced, and the mold needs to be replaced after processing the punching groove 3003 and then the punching opening, which adds an extra process and reduces production efficiency. Therefore, the inventor designed a transformer silicon steel sheet continuous punching and loading device. Summary of the invention

[0003] The object of the present invention is to provide a transformer silicon steel sheet continuous punching and loading device, which can automatically and continuously punch, break and stack silicon steel sheets, thereby greatly improving production efficiency.

[0004] In order to solve the above technical problems, the technical scheme of the present invention is: a transformer silicon steel sheet continuous punching and loading device, comprising a frame, a first cylinder, a slide, an upper die, a lower die, a first guide rod, a first spring, a guide rail mechanism, a left feeding mechanism, a material box mechanism, an insertion mechanism, a material blocking mechanism, a right feeding mechanism, a support, a second cylinder, a locking mechanism, a punching mechanism, and a loading mechanism. The first cylinder is arranged at the upper end of the frame, the slide is arranged at the lower end of the first cylinder, the slide slides along the up and down direction of the frame, the upper die is arranged at the lower end of the slide, the lower die is arranged at the lower end of the frame, the lower die is directly opposite to the upper die, the first guide rod passes through the slide, the first guide rod slides along the up and down direction of the slide, the first spring is arranged on the outside of the first guide rod, and the guide rail mechanism is located at the lower end of the first guide rod and is positioned At the upper end of the lower mold, the guide rail mechanism is connected to the first guide rod by bolts, the left feeding mechanism is arranged on the left side of the lower end of the slide, the material box mechanism is arranged on the left side of the lower end of the frame, the number of the insertion mechanisms is 2, and they are symmetrically arranged along the front and rear directions of the guide rail mechanism, the material blocking mechanism is located at the upper end of the insertion mechanism and located on the outside of the guide rail mechanism, the material blocking mechanism is threadedly connected to the guide rail mechanism, the right feeding mechanism is arranged on the right side of the lower end of the slide, the support is arranged on the right side of the lower end of the frame, the second cylinder is arranged at the lower end of the support, the locking mechanism is arranged at the upper left end of the support and located at the lower end of the guide rail mechanism, the locking mechanism is respectively connected to the support and the guide rail mechanism, the breaking mechanism is arranged at the upper end of the second cylinder, and the loading mechanism is arranged at the upper end of the guide rail mechanism and located on the right side of the right feeding mechanism.

[0005] The present invention is further improved as follows:

[0006] Furthermore, the guide rail mechanism includes a baffle, a loading plate, a guide wheel, a cutting hole, a limiting plate, a slide groove, and a proximity switch. The baffle is located at the lower end of the first guide rod, and the baffle is connected to the first guide rod by bolts. The loading plate is located at the lower end of the baffle, and the loading plate is connected to the baffle by bolts. The guide wheel is located at the lower end of the baffle, and the guide wheel is connected to the baffle by bolts. The cutting hole passes through the main body of the loading plate, and the axis of the cutting hole coincides with the axis of the upper mold and the lower mold respectively. The number of the limiting plates is 2, which are symmetrically arranged at the top of the loading plate. The slide groove is located on the left side of the loading plate. The proximity switch runs through the main body of the carrier plate, and is located at the lower left end of the carrier plate. The proximity switch is connected to the carrier plate by bolts. The gap height between the limiting plate and the carrier plate is 1.1 times the thickness of the side of the silicon steel sheet frame, which is convenient for continuous transportation of the silicon steel sheet frame. At the same time, the guide wheel fits the silicon steel sheet frame to facilitate its continuous transportation. When the silicon steel sheet on the silicon steel sheet frame moves to the cutting hole, the first cylinder drives the upper mold and the lower mold to close the mold to cut the connecting ribs of the silicon steel sheet but not cut it off. The carrier plate floats up and down with the slide, that is, it serves as a carrier of the silicon steel sheet frame, and is in close contact with the lower mold during stamping, effectively avoiding poor stamping caused by shaking.

[0007] Furthermore, the left feeding mechanism includes a slider, a second guide rod, an L-shaped push plate, a first wedge block, a second wedge block, a second spring, a material stripping mechanism, a limiting groove, a ball head, and a first limiting block. The slider is located at the lower end of the slide seat, and the slider is connected to the slide seat by bolts. One end of the second guide rod extends into the slider, and the second guide rod slides along the up and down directions of the slider. The L-shaped push plate is penetrated by the second guide rod and is located at the upper end of the baffle plate. The L-shaped push plate slides along the left and right directions of the second guide rod and the baffle plate. The first wedge block is located on the left side of the slider, and the first wedge block is connected to the slider by bolts. The second wedge block is located on the left side of the first wedge block and on the right side of the L-shaped push plate. The second wedge block is connected to the L-shaped push plate by bolts. The second spring is located on the outside of the second guide rod and on the left side of the L-shaped push plate. The number of the scraping mechanisms is 2, which are arranged in parallel at the lower end of the L-shaped push plate in the left and right directions. The limiting groove runs through the main body of the slider, the ball head is located on the right side of the second guide rod and on the outside of the limiting groove, the ball head is integrally connected to the second guide rod, the first limiting block is located on the inside of the L-shaped push plate and on the outside of the scraping mechanism, and the first limiting block is welded to the L-shaped push plate.

[0008] Furthermore, the stripping mechanism includes a swivel seat, a third guide rod, a stripping finger, a third spring, a second limit block, and a clamping port. The swivel seat is located at the lower end of the L-shaped push plate, the swivel seat is hinged to the L-shaped push plate, the third guide rod is located at the lower end of the swivel seat, the third guide rod is threadedly connected to the swivel seat, the stripping finger is located on the outside of the third guide rod, the stripping finger is connected to the third guide rod with a clearance fit, the third spring is located on the inside of the stripping finger and at the lower end of the third guide rod, the second limit block is located on the right side of the swivel seat and on the left side of the first limit block, and the The second limit block is welded to the swivel seat, and the clamping port is located at the lower right end of the material removal finger. The clamping port penetrates the material removal finger. When the first cylinder drives the guide rail mechanism to move downward, the lower mold contacts the carrier plate first, and the left feeding mechanism performs continuous conveying operations, which are as follows: the slider moves downward with the slide seat, driving the first wedge block to push the second wedge block downward. After the first wedge block is subjected to force, it moves in the direction away from the upper mold, thereby driving the L-shaped push plate to slide along the second guide rod and the baffle plate, and the material removal mechanism hinged to the L-shaped push plate rotates counterclockwise without performing any action on the silicon steel sheet frame in the carrier plate;When the first cylinder drives the guide rail mechanism to move upward, the slider moves upward with the slide seat, and the second spring resets to push the L-shaped push plate to slide along the second guide rod and the baffle plate. After the material-removing mechanism rotates counterclockwise to return to its initial position, the first limit block and the second limit block fit together, and the clamping opening at the lower end of the material-removing finger extends into the spacing groove on the silicon steel sheet frame to push the silicon steel sheet frame along the cavity composed of the limit plate and the carrier plate by a set distance (the distance is set to the width of the silicon steel sheet). Repeating the above actions can continuously feed the silicon steel sheet frame, and the ball head is in the limit position. The inner side of the groove slides to ensure the smooth and accurate movement of the L-shaped push plate. The axis of the pick-up mechanism forms an angle of 5° with the axis of the upper die, which can effectively prevent the situation where the lower end of the pick-up mechanism does not rotate after contacting the silicon steel sheet frame. Since the third spring is arranged on the inner side of the pick-up finger, an elastic floating connection is formed between the pick-up finger and the third guide rod, which can ensure the safety of the silicon steel sheet. The structure of the right feeding mechanism is the same as that of the left feeding mechanism. When assembling, the pick-up finger in the right feeding mechanism and the pick-up finger in the left feeding mechanism are in the same direction. The first limit block and the second limit block are both on the right side of the material removal mechanism, and the rest are symmetrically installed. This design can ensure the continuous transportation of the silicon steel sheet frame. The transportation process of the right feeding mechanism is as follows: when the first cylinder pushes the slide seat down, the driving slide block moves down, and the first wedge block pushes the second wedge block downward. After the first wedge block is subjected to force, it drives the L-shaped push plate to slide along the second guide rod and the baffle plate. Because the first limit block and the second limit block are fitted together for limiting, the material removal finger extends to the lower end of the material removal mechanism. The silicon steel sheet on the silicon steel sheet frame is pushed into the spacing groove on the silicon steel sheet frame along the baffle to set the distance. At the same time, the L-shaped push plate pushes the push rod to slide in the sheet loading seat, thereby pushing the silicon steel sheet adsorbed by the negative pressure of the suction cup ring into the sheet feeding groove. When the first cylinder pushes the slide seat downward, the first limit block and the second limit block are separated, and the material removal mechanism hinged with the L-shaped push plate rotates counterclockwise and does not move. Repeating the above actions can continuously feed the silicon steel sheet frame with equal spacing and continuously feed the silicon steel sheet after punching. ;

[0009] Furthermore, the material box mechanism includes an upper shell, a material box, a lower shell, a servo electric cylinder, a lower push plate, a fourth guide rod, an upper push plate, a fourth spring, and a spreader. The upper shell is located on the right side of the lower end of the frame, and the upper shell is connected to the frame by bolts. The material box is placed on the inner side of the upper shell, and the lower shell is located at the lower end of the upper shell. The lower shell is connected to the upper shell by bolts. The servo electric cylinder is located on the inner side of the lower shell, and the servo electric cylinder is connected to the lower shell by bolts. The lower push plate is located at the upper end of the servo electric cylinder and on the inner side of the lower shell. The lower push plate is connected to the servo electric cylinder by bolts. The lower push plate slides along the upper and lower directions of the lower shell. The fourth guide rod penetrates the lower push plate. The lower push plate slides in the up and down directions, the upper push plate is located at the upper end of the fourth guide rod, the upper push plate is threadedly connected to the fourth guide rod, the fourth spring is located on the outside of the fourth guide rod and between the upper push plate and the lower push plate, the number of the spreader is 2, and they are symmetrically arranged at the upper end of the upper shell body. When the proximity switch is triggered, the guide rail mechanism moves down with the first cylinder and fits with the upper shell body, and the servo electric cylinder pushes the lower push plate up. After the upper push plate is acted upon by the fourth spring, it pushes the stacked silicon steel sheet frame in the material box to move upward a set distance until the side of the top silicon steel sheet frame fits with the limiting plate. During this process, the spreader separates the silicon steel sheets, and the fourth spring elastically supports the upper push plate to form a flexible connection, thereby ensuring that the stacked silicon steel sheet frame is not damaged to the greatest extent.

[0010] Furthermore, the insertion mechanism includes a fifth guide rod, a connecting rod, a fifth spring, an insert rod, a limit sleeve, and a steel ball. The fifth guide rod is located outside the material loading plate, the fifth guide rod is threadedly connected to the material loading plate, the connecting rod is penetrated by the fifth guide rod, the connecting rod is connected to the fifth guide rod with clearance fit, the fifth spring is located outside the fifth guide rod and outside the connecting rod, the insert rod is located outside the connecting rod and penetrates the slide groove, the insert rod is connected to the connecting rod with interference fit, and the limit sleeves are 2 in number, which are symmetrically arranged along the front and rear directions of the insert rod. The steel ball passes through the insertion rod and is located on the inner side of the limit sleeve. When the proximity switch is triggered, the material box mechanism pushes the uppermost silicon steel sheet frame into place, and the second cylinder drives the inclined push head fixed to the support plate to move downward. Due to the action of the spreader, the two adjacent silicon steel sheets are separated. The fifth spring reset pushes the insertion rod fixed to the connecting rod through the slide groove and inserted between the uppermost silicon steel sheet frame and the second silicon steel sheet frame in the loading plate, thereby completing the loading of the silicon steel sheet frame. The steel ball rotates freely in the limit sleeve, thereby ensuring that the feeding mechanism continuously feeds the silicon steel sheet frame smoothly and without obstruction.

[0011] Furthermore, the material blocking mechanism also includes a hanging plate, a third cylinder, a support plate, and an oblique pushing head. The hanging plate is located at the lower end of the loading plate, and the hanging plate is connected to the loading plate by bolts.

The support plate is located at the upper end of the third cylinder, and the support plate is connected to the third cylinder by bolts. The oblique pushing head is located at the upper end of the support plate and at the upper end of the hanging plate, and the oblique pushing head is connected to the support plate by bolts and slides along the up and down directions of the hanging plate.

[0012] Furthermore, the locking mechanism also includes a locking cylinder, a locking rod, a latch, a sixth spring, a guide portion, and a locking groove. The locking cylinder is arranged at the upper end of the support, the lower end of the locking rod extends into the locking cylinder, the upper end of the locking rod is connected to the guide rail mechanism, one end of the latch extends into the locking cylinder, the sixth spring is arranged on the outside of the latch, the guide portion is arranged at the other end of the latch, and the locking groove passes through the locking rod.

[0013] Furthermore, the breaking mechanism also includes a top plate, a sixth guide rod, a seventh spring, a cutting head, a rubber column, and a force head. The top plate is located at the upper end of the second cylinder, the top plate is connected to the second cylinder by bolts, the sixth guide rod passes through the top plate and the support, the sixth guide rod is threadedly connected to the support, the seventh spring is located at the upper end of the top plate and located on the outside of the sixth guide rod, the cutting head is located at the center of the upper end of the top plate, the cutting head is connected to the top plate by bolts, the number of rubber columns is 2, which are symmetrically arranged along the left and right directions of the cutting head, and the force head is arranged on the outside of the top plate and is tightly attached to the guide part.

[0014] Furthermore, the film loading mechanism also includes a film loading seat, a film pushing rod, a cylinder body, a piston assembly, a gas distribution cylinder, a quick connector, a one-way valve, a connecting frame, a seventh guide rod, an air storage box, an eighth spring, a rubber airbag, a film loading box, a punching groove, a suction cup ring, a buffer groove, a ventilation cover, a film feeding groove, a regulating groove, and a spring. The film loading seat is arranged on the right side of the material loading plate, one end of the film pushing rod extends into the film loading seat, and the other end of the film pushing rod is connected to the right feeding mechanism. The cylinder body is arranged at the upper end of the film loading seat, and the lower end of the piston assembly extends into the cylinder body. The gas distribution cylinder is arranged at the upper end of the piston assembly, and the gas distribution cylinder is respectively connected to the piston assembly and the film loading seat, the quick connector is arranged outside the cylinder body, and the one-way valve is arranged at the lower end of the quick connector. The connecting frame is located on the right side of the gas distribution cylinder, the connecting frame is connected to the gas distribution cylinder, the seventh guide rod slides along the up and down direction of the connecting frame, the air storage box is arranged at the lower end of the seventh guide rod, the air storage box is connected to the quick connector through a hose, the eighth spring is arranged on the outside of the seventh guide rod, the rubber airbag is arranged at the lower end of the air storage box, the cavity of the rubber airbag is communicated with the cavity of the air storage box, the film loading box is arranged on the right side of the film loading seat, the punching groove is arranged on the left side of the film loading seat, the suction cup ring is arranged at the top of the punching groove, the buffer groove is arranged at the upper left end of the film loading seat, the cavity of the buffer groove is communicated with the cavity of the vent hole of the suction cup ring, the ventilation cover is arranged on the top of the buffer groove, and the ventilation cover is connected to the one-way valve The two springs are connected by a hose, the film conveying groove penetrates the film loading seat from left to right, the regulating groove is arranged on the right side of the film loading seat, the regulating groove penetrates the film conveying groove, and the spring is arranged on the upper end of the inner side of the film loading box. When the stacking height of the silicon steel sheets in the film loading box increases, the downward movement of the rubber airbag is blocked, and the eighth spring is compressed and moves upward for compensation, and at the same time exerts a reaction force to make the silicon steel sheets stacked neatly. When the first cylinder pushes the slide seat downward, it drives the right feeding mechanism to continuously transport the broken silicon steel sheets through the film conveying groove to the regulating groove, and is unable to fall into the film loading box due to the resistance of the spring. When the gas distribution cylinder moves downward, the piston assembly and the connecting frame move downward accordingly. When the piston arranged in the piston assembly moves downward with the gas distribution cylinder, the air in the cylinder body is first pressed into the rubber airbag so that the rubber airbag The bag expands slowly, and at the same time, the rubber airbag moves down and extends into the silicon steel sheet. In this process, the silicon steel sheet moves down under the limit of the spring and the action of the rubber airbag. When the height of the piston in the piston assembly is lower than the height of the quick connector, since the upper end opening of the cylinder body is the same as the atmosphere, the rubber airbag shrinks immediately, and the silicon steel sheet falls into the loading box under the action of gravity. By repeating the above actions, the silicon steel sheets can be automatically stacked in the loading box. When the gas distribution cylinder moves upward, the one-way valve is unidirectional, thereby sucking the vent hole of the suction cup ring into negative pressure through the ventilation cover and the buffer groove. When the second cylinder pushes the cutting mechanism upward to separate the silicon steel sheet from the silicon steel sheet frame and send it into the punching groove, the suction cup ring absorbs the silicon steel sheet due to the negative pressure at the suction cup ring to prevent it from falling off.

[0015] Compared with the prior art, the transformer silicon steel sheet continuous punching and loading device, when working, first loads the silicon steel sheet frame into the material box in the material box mechanism, and then pushes the uppermost silicon steel sheet frame into place, the blocking mechanism is actuated, and the fifth spring in the insertion mechanism is reset to insert the insertion rod between the uppermost silicon steel sheet frame and the second silicon steel sheet frame, and the uppermost silicon steel sheet frame stays in the area composed of the limiting plate and the insertion rod, then the material box mechanism is reset, the first cylinder pushes the slide seat up and down to drive the left feeding mechanism to continuously transmit the silicon steel sheet frame with equal step distance, and when the silicon steel sheet frame When the silicon steel sheet on the upper reaches the cutting hole, the first cylinder pushes the guide rail mechanism downward, and the guide rail mechanism first contacts the lower mold and stops moving downward. The upper mold connected to the slide seat moves further downward with the first cylinder and closes the mold with the lower mold to cut the connecting ribs of the silicon steel sheet but does not cut it off. Then, the first cylinder moves up and resets, and the above steps are repeated until the silicon steel sheet frame moves to the right feeding mechanism. When the right feeding mechanism transports the silicon steel sheet frame to the top of the punching mechanism, the punching mechanism punches the silicon steel sheet from the silicon steel sheet frame and sends it into the loading mechanism, and then under the continuous transportation of the right feeding mechanism, the stacking loading is completed. The device has a simple structure, and can perform cutting and equal-spaced feeding operations through a single action of a single first cylinder, realizing the punching, punching and stacking of silicon steel sheets, greatly improving production efficiency.

When the first cylinder 2 drives the guide rail mechanism 8 to move downward, the lower mold 5 first contacts the loading plate 802, and the left feeding mechanism 9 performs continuous conveying operations, which are as follows: the slider 901 moves downward with the slide seat 3, driving the first wedge block 904 to push the second wedge block 905 downward. After the first wedge block 905 is subjected to force, it moves in the direction away from the upper mold 4, thereby driving the L-shaped push plate 903 to slide along the second guide rod 902 and the baffle 801.The material stripping mechanism 907 hinged to the L-shaped push plate 903 rotates counterclockwise without performing any action on the silicon steel sheet frame in the loading plate 802; when the first cylinder 2 drives the guide rail mechanism 8 to move upward, the slider 901 moves upward with the slide seat 3, and the second spring 906 resets to push the L-shaped push plate 903 to slide along the second guide rod 902 and the baffle 801. After the material stripping mechanism 907 rotates counterclockwise to return to its initial position, the first limit block 910 and the second limit block 915 fit together, and the clamping port 916 at the lower end of the material stripping finger 914 extends into the spacing groove 3003 on the silicon steel sheet frame to push the silicon steel sheet frame along the cavity formed by the limit plate 805 and the loading plate 802 by a set distance (the distance is set The width of the silicon steel sheet is determined by repeating the above-mentioned actions, so that the silicon steel sheet frame can be continuously fed. The ball head 909 slides inside the limiting groove 908 to ensure the smooth and accurate movement of the L-shaped push plate 903. The axis of the material stripping mechanism 907 forms an angle of 5° with the axis of the upper mold 4, which can effectively prevent the lower end of the material stripping mechanism 907 from not rotating after contacting the silicon steel sheet frame. Since the third spring 914 is arranged on the inner side of the material stripping finger 913, an elastic floating connection is formed between the material stripping finger 913 and the third guide rod 912, which can ensure the safety of the silicon steel sheet. The structure of the right feeding mechanism 13 is the same as that of the left feeding mechanism 9. During assembly, the material stripping in the right feeding mechanism 13 Finger 913 is installed in the same direction as the material-removing finger 913 in the left feeding mechanism 9 (as shown in the figure, the clamping port 916 is horizontally facing the right side), and the first limit block 910 and the second limit block 916 are both on the right side of the material-removing mechanism 907, and the rest are symmetrically installed. Such a design can ensure the continuous transportation of the silicon steel sheet frame. The transportation process of the right feeding mechanism 13 is as follows: when the first cylinder 2 pushes the slide 3 to move downward, the driving slider 901 moves downward, and the first wedge block 904 pushes the second wedge block 905 downward. After the first wedge block 905 is subjected to force, it drives the L-shaped push plate 903 to slide along the second guide rod 902 and the baffle 2. Because the first limit block 910 and the second limit block 916 are fitted together for limiting, the material-removing The clamping opening 916 at the lower end of the finger 914 extends into the spacing groove 3003 on the silicon steel sheet frame to push the silicon steel sheet on the silicon steel sheet frame along the baffle 801 to set the distance. At the same time, the L-shaped push plate 903 pushes the push rod 1802 to slide in the sheet loading seat 1801, and then pushes the silicon steel sheet adsorbed by the negative pressure of the suction cup ring 1815 into the sheet conveying groove 1818. When the first cylinder 2 pushes the slide 3 downward, the first limit block 910 and the second limit block 916 separate, and the material removal mechanism 907 hinged to the L-shaped push plate 903 rotates counterclockwise and does not move. Repeating the above actions can continuously feed the silicon steel sheet frame with equal spacing and continuously feed the silicon steel sheet after punching.

When the stacking height of the silicon steel sheets in the film loading box 1813 increases, the rubber airbag 1812 is blocked from moving downward, and the eighth spring 1811 is pressed and moves upward for compensation, and at the same time exerts a reaction force to make the silicon steel sheets stacked neatly. When the first cylinder 2 pushes the slide 3 to move downward, it drives the right feeding mechanism 13 to continuously transport the broken silicon steel sheets to the regulating groove 1819 through the film conveying groove 1818.The resistance of the spring piece 1820 prevents it from falling into the film loading box 1813. When the gas distribution cylinder 1805 moves downward, the piston assembly 1804 and the connecting frame 1808 move downward accordingly. When the gas distribution cylinder 1805 moves downward, the piston in the piston assembly 1804 first presses the air in the cylinder into the rubber airbag 1812 to slowly expand the rubber airbag. At the same time, the rubber airbag 1812 moves downward and extends into the silicon steel sheet. In this process, the silicon steel sheet moves downward under the limit of the spring piece 1820 and the action of the rubber airbag 1812. When the height of the piston in the piston assembly 1804 is lower than the height of the quick connector 1806, due to the cylinder 180 3 has the same upper opening as the atmosphere, the rubber airbag 1812 shrinks immediately, and the silicon steel sheet falls into the sheet loading box 1813 under the action of gravity. By repeating the above actions, the silicon steel sheet can be automatically stacked in the sheet loading box 1813. When the gas cylinder 1805 moves upward, the one-way valve 1807 is unidirectional, so that the vent hole of the suction cup ring 1815 is sucked into negative pressure through the ventilation cover 1817 and the buffer groove 1816. When the second cylinder 15 pushes the cutting mechanism 17 upward to separate the silicon steel sheet from the silicon steel sheet frame and send it into the punching groove 1814, due to the negative pressure at the suction cup ring 1815, the suction cup ring 1815 absorbs the silicon steel sheet to prevent it from falling off.
