Description

Technical Field

[0001] This utility model relates to the technical field of coil housing processing, specifically a coil housing notch stamping mechanism. Background Technology

[0002] A coil housing is a component used to protect and support the coil, typically made of metal. Its main function is to protect the coil from external environmental influences, preventing mechanical damage, chemical corrosion, electromagnetic interference, and other harmful factors. Furthermore, the coil housing enhances the coil's rigidity and stability, ensuring stable operation. Traditionally, during the stamping process, workers place the coil housing on the stamping equipment, and after stamping, remove it to prepare for the next coil to be stamped.

[0003] Chinese Patent Announcement CN221209546U discloses a coil housing notch stamping mechanism. Its key technical features include: a punch press with a punch head; punch plates disposed on the punch press, forming a clamping channel between the punch plates; two clamping plates driven opposingly by a first driving cylinder within the clamping channel, forming a groove between the two clamping plates for accommodating the coil housing; a fixing member driven by a second driving cylinder to insert and fix the coil housing located in the groove; a first notch formed at the top of the fixing member for stamping the coil housing, and a second notch formed at the bottom of the fixing member for discharging waste material; and an electromagnet installed within the fixing member to attract waste material into the second notch.

[0004] In the above scheme, the waste material falls into the second gap through the first gap and is attracted by the electromagnet. Then the fixing part drives the waste material out of the coil housing. Then the electromagnet is controlled to no longer attract the waste material located in the second gap inside the fixing part. The waste material falls through the second gap, resulting in the following disadvantage: when the stamping mechanism is in use, it cannot automatically discharge the waste material and only relies on its own gravity to fall. Utility Model Content

[0005] The purpose of this invention is to provide a coil housing notch stamping mechanism to solve the problem that the stamping mechanism cannot automatically discharge waste material during use and relies solely on its own gravity to fall.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a coil shell notch stamping mechanism, including a punch, the punch being disposed on a punch press, a punch plate being fixed on the punch press, a movable hole being opened on the top surface of the punch plate, a connecting hole being opened on the left side of the inner wall of the movable hole, a first driving cylinder being fixed on the left side of the punch plate, one end of the telescopic rod of the first driving cylinder being slidably inserted into the connecting hole and fixed with an mounting cylinder, an electric push rod being fixed inside the mounting cylinder, a fixing member being fixed on the right end of the mounting cylinder, one end of the telescopic rod of the electric push rod being slidably inserted into the fixing member, a first notch being opened on the top surface of the fixing member, a second notch being opened on the bottom surface of the fixing member, the second notch being larger than the first notch.

[0007] Preferably, a second drive cylinder is fixed to the front and rear sides of the punch plate, and one end of the telescopic rod of the two second drive cylinders passes through the punch plate and is fixed with an arc-shaped clamping plate.

[0008] Preferably, two sliding grooves are respectively opened on the left and right sides of the inner wall of the movable hole, and sliders are respectively fixed on the left and right sides of the two arc-shaped clamps, and the two sliders are slidably arranged in the two sliding grooves.

[0009] Preferably, the inner walls of the two arc-shaped clamps are respectively fixed with rubber pads, and the inner sides of the two rubber pads are respectively provided with anti-slip texture.

[0010] Preferably, a collection box is fixed on the punch press, and an inclined plate is fixed on the top surface of the collection box.

[0011] Preferably, a partition plate is fixed inside the collection box, a drive motor is fixed to the rear side of the inclined plate, the output shaft of the drive motor passes through the inclined plate, and a blocking plate is fixed thereon.

[0012] Compared with the prior art, the coil housing notch stamping mechanism that adopts the above technical solution has the following advantages:

[0013] 1. In use, through the coordinated use of punch, punch press, punch plate, movable hole, connecting hole, first drive cylinder, mounting cylinder, electric push rod, fixing parts, first notch and second notch, the automatic discharge of waste material is realized, which effectively prevents the waste material from getting stuck inside the fixing parts and further ensures the smooth operation of production;

[0014] Second, during use, the second drive cylinder pushes the two arc-shaped clamping plates closer together until they are tightly fitted against the coil housing, improving the stability of the coil housing during the stamping process. When the arc-shaped clamping plates move back and forth via the second drive cylinder, the slider slides inside the groove, ensuring that the arc-shaped clamping plates do not shift or wobble during movement, thus improving the stability of the arc-shaped clamping plates during movement. This provides protection for the coil housing during clamping, preventing wear on the surface of the coil housing. Simultaneously, the anti-slip texture on the rubber pad surface increases the friction between the two, improving stability.

[0015] Third, during use, waste materials and coil housings automatically slide along the inclined plate into the collection box, ensuring their smooth entry and preventing them from scattering around the punch press. Guiding the coil housings into the right cavity of the collection box achieves separate collection of waste materials and stamped coil housings, facilitating sorting and processing by workers, improving the efficiency of subsequent production processes, and providing convenience for production management.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3As shown, a coil housing notch stamping mechanism includes a punch 1, which is mounted on a punch press 2. Both the punch 1 and the punch press 2 are existing structures, and can be found in Chinese Patent Publication No. CN221209546U. The punch 1 and punch press 2 in this application are the same as those in the referenced document. A punch plate 3 is fixed on the punch press 2. The top surface of the punch plate 3 has a movable hole 4, and the left side of the inner wall of the movable hole 4 has a connecting hole 5. A first driving cylinder 6 is fixed on the left side of the punch plate 3. One end of the telescopic rod of the first driving cylinder 6 is slidably inserted into the connecting hole 5 and a mounting cylinder 7 is fixed thereon. An electric push rod 8 is fixed inside the mounting cylinder 7. A fixing member 9 is fixed on the right end of the mounting cylinder 7. One end of the telescopic rod of the electric push rod 8 is slidably inserted into the fixing member 9. A first notch 10 is opened on the top surface of the fixing member 9, and a second notch 11 is opened on the bottom surface of the fixing member 9. The second notch 11 is larger than the first notch 10.

[0023] In operation, the operator first places the coil shell to be processed into the movable hole 4 of the punch plate 3. Then, the first drive cylinder 6 is activated, and its telescopic rod slides smoothly in the connecting hole 5, driving the mounting cylinder 7 to move to the right. This allows the fixing part 9 to accurately enter the interior of the coil shell for fixation. Then, the punch 1 is driven by the punch press 2 to perform a stamping operation on the coil shell. The waste material generated during the stamping process falls into the second notch 11 below through the first notch 10. After the stamping is completed, the first drive cylinder 6 is controlled to retract, and the fixing part 9 pulls the waste material out of the coil shell. At the same time, the operator activates the electric push rod 8, whose telescopic rod extends into the fixing part 9, pushing the waste material out of the second notch 11. The waste material then falls through the movable hole 4, and the stamped coil shell also falls through the movable hole 4. This simplifies the production process, reduces the tedious steps of manually removing the stamped coil shell, improves production efficiency, and reduces the safety risks that operators may suffer from direct contact with the equipment during operation, providing a higher level of safety for production operations. By using punch 1, punch press 2, punch plate 3, movable hole 4, connecting hole 5, first drive cylinder 6, mounting cylinder 7, electric push rod 8, fixing part 9, first notch 10 and second notch 11 in combination, the automatic discharge of waste material is realized, which effectively prevents the waste material from getting stuck inside the fixing part 9 and further ensures the smooth progress of production.

[0024] like Figures 1-3 As shown, the front and rear sides of the punch plate 3 are respectively fixed with second drive cylinders 12, and one end of the telescopic rod of the two second drive cylinders 12 passes through the punch plate 3 and is respectively fixed with arc-shaped clamping plates 13.

[0025] During use, after the coil housing is initially fixed by the fixing component 9, the operator immediately activates the two second drive cylinders 12 to push the two arc-shaped clamps 13 closer together until they are tightly attached to the coil housing for further clamping and fixing. After the stamping operation is completed, the second drive cylinders 12 are activated again to move the two arc-shaped clamps 13 away from each other and release the clamping of the coil housing. At this time, the stamped coil housing falls from the movable hole 4 under the action of gravity, which improves the stability of the coil housing during the stamping process.

[0026] like Figure 2 and Figure 3 As shown, two sliding grooves 14 are respectively opened on the left and right sides of the inner wall of the movable hole 4. Slider 15 is fixed on the left and right sides of the two arc-shaped clamps 13 respectively. The two sliders 15 are slidably arranged in the two sliding grooves 14. Rubber pads 16 are fixed on the inner walls of the two arc-shaped clamps 13 respectively. Anti-slip textures 17 are provided on the inner side of the two rubber pads 16 respectively.

[0027] During use, when the arc-shaped clamping plate 13 moves back and forth via the second drive cylinder 12, the slider 15 slides inside the groove 14, ensuring that the arc-shaped clamping plate 13 does not shift or wobble during movement, thus improving the stability of the arc-shaped clamping plate 13 during movement. When the arc-shaped clamping plate 13 clamps and fixes the coil shell, the rubber pad 16 makes close contact with the outer wall of the coil shell, which can protect the coil shell during clamping and prevent wear on the surface of the coil shell. At the same time, the anti-slip texture 17 on the surface of the rubber pad 16 increases the friction between the two, improving stability.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a collection box 18 is fixed on the punch press 2, an inclined plate 19 is fixed on the top surface of the collection box 18, a partition plate 20 is fixed inside the collection box 18, a drive motor 21 is fixed on the rear side of the inclined plate 19, the output shaft of the drive motor 21 passes through the inclined plate 19, and a blocking plate 22 is fixed thereon.

[0029] During use, when scrap or stamped coil housings fall from the movable hole 4, they first land on the inclined plate 19 on the top surface of the collection box 18. Since the inclined plate 19 has a certain angle of inclination, the scrap and coil housings will automatically slide into the interior of the collection box 18 along the inclined plate 19, so that they can enter the collection box 18 smoothly and avoid the scrap and coil housings from scattering around the punch press 2. The partition plate 20 inside the collection box 18 divides the collection box 18 into two chambers, left and right. When waste material falls from the movable hole 4, the operator starts the drive motor 21. The output shaft of the drive motor 21 drives the baffle plate 22 to rotate clockwise, guiding the waste material into the left chamber of the collection box 18. When the stamped coil shell falls from the movable hole 4, the drive motor 21 is started again, causing the baffle plate 22 to rotate counterclockwise, guiding the coil shell into the right chamber of the collection box 18. This achieves the separate collection of waste material and stamped coil shell, making it easier for operators to classify and process waste material and coil shell, improving the efficiency of subsequent production processes, and also providing convenience for production management.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
