Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically a shearing machine for shearing transformer cores. Background Technology

[0002] Transformer cores are typically made of silicon steel sheets. Silicon steel is a type of steel containing silicon, with a silicon content ranging from 0.8% to 4.8%. Silicon steel is used for transformer cores because it is a highly permeable magnetic material. In a current-carrying coil, it can generate a large magnetic induction intensity, thus allowing for a smaller transformer size. During the manufacturing process of transformer cores, a shearing machine is used to cut the material into the required dimensions.

[0003] The prior art, with publication number CN222710964U, discloses a shearing machine for shearing transformer cores, including an equipment frame and a top frame. The top frame is fixed on the equipment frame, and a bottom groove is opened on the surface of the equipment frame. Supporting hydraulic cylinders are all installed at the bottom of the equipment frame. A processing platform is connected to the output end of the supporting hydraulic cylinders and is located in the bottom groove. A feeding and straightening component is set on the processing platform, a shearing component is set on the processing platform and the top frame, and a pushing component is set on the processing platform. The pushing component includes a pair of long grooves, both of which are opened on the surface of the processing platform, and notches are opened at both ends of the long grooves.

[0004] The current shearing machine can only fix one side of the material cutting position during use, while the other side lacks a fixing structure. This causes the unfixed side of the material to wobble during cutting, resulting in poor fixing effect and poor cutting stability. This may affect the flatness of the cut and reduce the quality of shearing. Therefore, a shearing machine for transformer core cutting is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a shearing machine for shearing transformer cores, which has advantages such as good fixing effect and stable shearing. It solves the problem that existing shearing machines for shearing transformer cores can only fix one side of the material being cut, while the other side lacks a fixing structure, causing the unfixed side of the material to easily shake during shearing, resulting in poor fixing effect and thus poor shearing stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shearing machine for shearing transformer cores, comprising a frame, a processing table fixedly connected to the inner side of the frame, and a gantry frame fixedly connected to the top of the frame, wherein a positioning component is provided on the gantry frame;

[0007] The positioning assembly includes a first hydraulic cylinder fixedly installed on the top of the gantry and a connecting frame fixedly installed on the output shaft of the first hydraulic cylinder. Two mounting columns penetrating to the inside of the gantry are fixedly installed at the bottom of the connecting frame. A positioning plate is fixedly connected to the lower end of the mounting columns, and a shearing mechanism is provided on the upper side of the positioning plate.

[0008] The shearing mechanism includes a fixed frame located inside the gantry frame. The fixed frame is fixedly installed between two mounting columns. A second hydraulic cylinder is fixedly installed on the upper side of the fixed frame. A mounting plate is fixedly installed on the output shaft of the second hydraulic cylinder. A shearing blade is fixedly installed on the bottom of the mounting plate.

[0009] Furthermore, a discharge plate is provided on one side of the processing table, the discharge plate is inclined, and a guide component is provided on the side of the gantry away from the discharge plate.

[0010] Furthermore, the guide assembly includes two fixed plates fixedly connected to the top of the processing table, and each of the two fixed plates is elastically connected to a guide plate on one side facing each other.

[0011] Furthermore, electric push rods are installed between the two fixed plates and the corresponding guide plates, and arc-shaped plates are fixedly connected to the ends of the two guide plates away from the gantry frame, with the two arc-shaped plates being symmetrical to each other.

[0012] Furthermore, a fixed column is fixedly connected to the top of the gantry frame, and a first slider is fixedly connected to the outer wall of the mounting column. A first sliding groove is provided on the outer wall of the fixed column, and the first slider slides in cooperation with the inner side of the first sliding groove.

[0013] Furthermore, a second slider is fixedly connected to the side of the mounting plate, and a second groove is provided on the outer wall of the mounting column, with the second slider slidably connected to the inner side of the second groove.

[0014] Furthermore, the positioning plate has a vertically extending slot, which is opposite to the position of the shearing blade.

[0015] Furthermore, a shearing groove adapted to the shearing blade is provided on the outer wall of the processing table, and the shearing groove is positioned opposite to the strip opening.

[0016] Furthermore, an annular rubber pad is fixedly connected to the bottom of the positioning plate, and the annular rubber pad has a through-center design.

[0017] Furthermore, multiple conveying rollers are rotatably mounted on the inner side of the processing table.

[0018] Compared with the prior art, this utility model provides a shearing machine for cutting transformer cores, which has the following advantages:

[0019] 1. This transformer core shearing machine integrates the positioning component and the shearing mechanism. When shearing materials, the positioning plate fixes the materials. Since the materials are fixed around the shearing blade, both sides of the material's shearing position are well fixed. Compared with setting a fixing structure only on one side of the material, this method can better ensure the stability of the shearing, improve the shearing quality, and has high practicality.

[0020] 2. The shearing machine for shearing transformer cores has a set of guiding components that facilitate the guidance and conveying of materials, which helps to ensure that the materials are placed neatly and improves the shearing quality. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 7 The transformer core shearing machine in this embodiment includes a frame 1, a processing table 2 fixedly connected to the inside of the frame 1, and a gantry frame 3 fixedly connected to the top of the frame 1.

[0031] Please see Figure 1 and Figure 2 The gantry 3 is equipped with a positioning assembly 4, which includes a first hydraulic cylinder 401 fixedly mounted on the top of the gantry 3 and a connecting frame 402 fixedly mounted on the output shaft of the first hydraulic cylinder 401. Two mounting columns 403, penetrating to the inside of the gantry 3, are fixedly mounted on the bottom of the connecting frame 402. A positioning plate 404 is fixedly connected to the lower end of each mounting column 403. The first hydraulic cylinder 401 drives the connecting frame 402 and the mounting columns 403 to move downwards, thereby causing the positioning plate 404 to move downwards, enabling the positioning plate 404 to clamp and fix the material on the processing table 2.

[0032] Please see Figure 5 and Figure 6 It should be noted that the positioning plate 404 has a vertically through slot 405, and the bottom of the positioning plate 404 is fixedly connected to an annular rubber pad 406, which has a through-center design.

[0033] It should be noted that a fixed column 407 is fixedly connected to the top of the gantry 3, and a first slider 408 is fixedly connected to the outer wall of the mounting column 403. A first sliding groove is provided on the outer wall of the fixed column 407, and the first slider 408 slides in cooperation with the inner side of the first sliding groove. The cooperation between the first slider 408 and the fixed column 407 can guide the mounting column 403 and improve the stability of the structure.

[0034] Please see Figure 1 , Figure 3 and Figure 4The positioning plate 404 is provided with a shearing mechanism 5 on its upper side. The shearing mechanism 5 is located on a fixed frame 501 inside the gantry frame 3. The fixed frame 501 is fixedly installed between two mounting columns 403. A second hydraulic cylinder 502 is fixedly installed on the upper side of the fixed frame 501. A mounting plate 503 is fixedly installed on the output shaft of the second hydraulic cylinder 502. A shearing blade 504 is fixedly installed on the bottom of the mounting plate 503. The second hydraulic cylinder 502 can drive the mounting plate 503 to move downward, thereby driving the shearing blade 504 to move, which facilitates the shearing operation.

[0035] It should be noted that the strip-shaped opening 405 is positioned opposite to the shearing blade 504, and the strip-shaped opening 405 is located directly below the shearing blade 504. This allows the shearing blade 504 to pass through the positioning plate 404 to shear the material below it. The outer wall of the processing table 2 is provided with a shearing groove that is compatible with the shearing blade 504. The shearing groove is positioned opposite to the strip-shaped opening 405, and the shearing groove is located directly below the strip-shaped opening 405. The shearing groove allows the shearing blade 504 to easily penetrate deep into the material, ensuring complete shearing.

[0036] It should be noted that a second slider 505 is fixedly connected to the side of the mounting plate 503, and a second groove is provided on the outer wall of the mounting column 403. The second slider 505 is slidably connected to the inner side of the second groove. The cooperation between the second slider 505 and the mounting column 403 can guide the mounting plate 503 and improve the stability of the structure.

[0037] In addition, a discharge plate 7 is provided on one side of the processing table 2. The discharge plate 7 is inclined, and a guide component 6 is provided on the side of the gantry frame 3 away from the discharge plate 7.

[0038] Please see Figure 1 and Figure 7 The guide assembly 6 includes two fixed plates 601 fixedly connected to the top of the processing table 2. Each of the two fixed plates 601 is elastically connected to a guide plate 602 on one side facing each other. An electric push rod 603 is installed between each of the two fixed plates 601 and the corresponding guide plate 602. An arc plate 604 is fixedly connected to the end of each guide plate 602 away from the gantry 3. The two arc plates 604 are symmetrical to each other. The two arc plates 604 facilitate the guidance of materials between the two guide plates 602. The electric push rod 603 is fixedly installed on the fixed plate 601. The guide plate 602 is fixedly connected to the output shaft of the electric push rod 603. The position of the guide plate 602 is adjusted by the electric push rod 603 to adapt to materials of different widths.

[0039] It should be added that multiple conveying rollers 8 are rotatably installed on the inner side of the processing table 2. The upper surface of the conveying rollers 8 is higher than the upper surface of the processing table 2, so as to minimize the contact area between the material and the surface of the processing table when conveying the material, thereby reducing wear.

[0040] The working principle of the above embodiments is as follows:

[0041] In use, the guide plate 602 is moved by the electric push rod 604. The two guide plates 602 are adjusted to a suitable distance according to the material width. The material to be cut is guided by the two arc plates 604 and conveyed between the two guide plates 602 to ensure that the material is neatly arranged. When the material is pushed to the bottom of the gantry 3 by the conveying roller 8, the first hydraulic cylinder 401 is activated to drive the connecting frame 402 and the mounting column 403 to move downward, and also to drive the positioning plate 404 to move downward, so that the positioning plate 404 can clamp and fix the material. Then, the second hydraulic cylinder 502 is activated to drive the mounting plate 503 to move downward, and also to drive the shearing blade 504 to pass through the positioning plate 404 to cut the material. Since the material is fixed around the shearing blade 504, both sides of the material cutting position are well fixed, ensuring the stability of the cutting.

[0042] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
