The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration, and do not represent the only embodiment.

[0030] The utility model will be further described in combination with the drawings and specific embodiments.

[0031] In combination Figures 1-6 The embodiment discloses a transformer silicon steel sheet cutting equipment, which aims to reduce the frictional resistance of the silicon steel sheet in the cutting process by optimizing the design of the feeding mechanism, improve the feeding smoothness, thereby improving the cutting efficiency and product quality.

[0032] The transformer silicon steel sheet cutting equipment comprises a cutting table 100 arranged horizontally, in order to enhance the stability and bearing capacity of the cutting table 100, the cutting table 100 is a horizontal rectangular plate body structure, the bottom of the cutting table 100 is provided with supporting legs 101 to support the whole cutting equipment, the height and number of the supporting legs 101 can be adjusted according to actual needs to ensure the levelness and stability of the cutting table 100.

[0033] The cutting table 100 is provided with an "n"-shaped support 200, the bottom of the support 200 is arranged on the cutting table 100, and is fixed through welding to provide a stable support structure.

[0034] The support 200 is equipped with a lifting drive component 210, which is specifically a cylinder. The main body of the lifting drive component 210 is fixed on the support 200. Its transmission output end is vertically downward and connected to a lifting module 220. The lifting module 220 includes a lifting plate that can be controlled to move up and down by the lifting drive component 210. The lifting plate is a horizontal rectangular plate with its length direction parallel to the left and right directions. The bottom of the lifting plate is equipped with a cutting blade 221 with the blade facing downward. The top of the cutting blade 221 is detachably connected to the lifting plate through a blade holder, which facilitates the replacement of the cutting blade 221.

[0035] The cutting table 100 is located directly below the cutter 221 and has a retraction groove 102 to prevent interference during the cutting process and to facilitate smooth retraction after cutting. During operation, the lifting drive 210 can drive the cutter 221 to move vertically downward to cut the silicon steel sheet located below.

[0036] To optimize the design of the feeding mechanism, the cutting table 100 has three spaced-apart first hollow slots 103 on both sides of the blade relief groove 102. The first hollow slots 103 longitudinally penetrate the cutting table 100, and feeding rollers 300 are fitted with a clearance fit at the bottom of each slot. The feeding rollers 300 are horizontally positioned, and their axial ends are connected to the linkage frame 310 via bearings, forming a rolling support structure. During operation, the silicon steel sheets can be placed on the feeding rollers 300 during loading and unloading. The feeding rollers 300 provide suitable elastic support, elevating the silicon steel sheets away from the cutting table 100, effectively reducing friction during loading and unloading and improving feeding smoothness.

[0037] The cutting table 100 is located at the bottom of the linkage frame 310 and is equipped with a support plate 105, which is an "L" shaped plate structure. The four support plates 105 and the support springs 106 are evenly supported at the bottom of the linkage frame 310 so that each feed roller 300 can move up and down synchronously.

[0038] A support spring 106 is provided between the top of the tray 105 and the bottom of the linkage frame 310, in conjunction with... Figure 6 As shown, the support spring 106 is a simplified drawing. In reality, the support spring 106 is constrained by the limiting groove on the support plate 105 and the linkage frame 310 to maintain a stable vertical posture. The longitudinal extension stroke of the support spring 106 at the top of the feeding roller 300, which supports the silicon steel sheet, is greater than the exposed height of the top of the feeding roller 300 relative to the cutting table 100. This allows the top of the feeding roller 300 to sink below the first hollow groove 103 after the linkage frame 310 receives appropriate downward pressure. In other embodiments, to further ensure the accuracy and reliability of the lifting path of the feeding roller 300, a vertical guide rod is also provided between the linkage frame 310 and the cutting table 100.

[0039] In order to improve the cutting accuracy and stability, the lifting module 220 is provided with a plurality of elastic pressure rods 222 on the front and rear sides of the cutter 221. In the free state, the bottom end of the elastic pressure rod 222 is lower than the bottom end of the cutter 221, and after the elastic pressure rod 222 is pressed down to hold the silicon steel sheet, the bottom end of the elastic pressure rod 222 can be elastically displaced above the bottom end of the cutter 221, ensuring smooth cutting while performing stable and reliable material pressing treatment, preventing the silicon steel sheet from shifting or warping during cutting.

[0040] Further, the lifting module 220 is also provided with a top block 223 on the left and right sides of the cutter 221, the top end of the top block 223 is connected with the lifting plate, and the bottom end of the top block 223 is a free end. The second hollow groove 104 is vertically through the cutting table 100, and the top block 223 can pass through the second hollow groove 104 and press down the linkage frame 310 after following the lifting plate downward, so as to make the material feeding roller 300 sink, so that the silicon steel sheet is attached to the cutting table 100, and the elastic pressure rod 222 realizes a more ideal material pressing control effect.

[0041] It should be noted that the bottom end of the top block 223 is lower than the bottom end of the cutter 221, which makes the cutter 221 not reach the cutting position, and the bottom of the top block 223 completes the effect of pressing down the linkage frame 310 in advance.

[0042] In order to make the structure more flexible, it is convenient to replace the top block 223 of different height specifications according to the actual production needs, and a detachable connection structure is arranged between the top of the top block 223 and the lifting plate, which is realized by bolt locking.

[0043] In the specific implementation process, the silicon steel sheet is fed from the front side of the cutting table 100 and placed on the top of the material feeding roller 300 in the front side area. The material feeding roller 300 provides elastic support, which is conducive to reducing the rigid collision of the silicon steel sheet before cutting, ensuring the integrity of the quality, and the material feeding roller 300 also has the effect of rolling feeding, so that the silicon steel sheet can easily and smoothly enter the cutting position. When cutting, the lifting drive 210 drives the lifting plate to move downward, synchronously driving the cutter 221, the elastic pressure rod 222 and the top block 223 to move downward, the top block 223 passes through the second hollow groove 104 to press down the linkage frame 310, so that the material feeding roller 300 sinks synchronously, the silicon steel sheet in the cutting position loses the support of the material feeding roller 300 and is attached to the flat top surface of the cutting table 100, and then the elastic pressure rod 222 holds and fixes it, ensuring that it will not easily slide out of position during cutting. Finally, the cutter 221 moves downward to the cutting height to cut the silicon steel sheet, and after completion, the lifting module 220 moves upward to reset, and the material feeding roller 300 also moves upward to reset, again supporting the silicon steel sheet for easy material feeding operation.

[0044] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
