Abstract
Description
Technical Field
[0001] This invention relates to the field of cutting device technology, and in particular to a metal cutting device for power bridging components. Background Technology
[0002] Metal plates are used for conductivity in the manufacturing process of a series of power bridging components such as circuit breakers and disconnect switches. Since the metal plates are generally small sheet-like structures, cutting equipment is needed to cut large metal plates into equal parts during production.
[0003] However, existing cutting equipment cannot effectively guarantee the cutting length of products. Therefore, high-precision measuring equipment is generally used to check the cutting length during cutting to ensure that the cutting length meets the standard. However, this method can easily lead to increased production and maintenance costs. A cheaper method is to manually measure and then cut the product. This can easily affect the cutting accuracy, increase labor intensity, and reduce production efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a metal cutting device for power bridging components.
[0005] The technical problem of this invention is mainly solved by the following technical solution:
[0006] A metal cutting device for an electrical bridging component includes a base plate with mounting plates on both sides of its top. Limiting plates are provided on both sides between two sets of mounting plates. A screw I, with its end connected to a corresponding limiting plate via a bearing, is screwed onto each mounting plate. An L-shaped plate, located between the two limiting plates and inverted, is provided on one side of the top of the base plate. The L-shaped plate is driven by an electric push rod. A frame is provided on the other side of the top of the base plate, housing a cutting blade assembly driven by a hydraulic rod. A flat box, on the same side as the cutting blade assembly, is provided on the outer side of the base plate, with its opening facing the cutting blade assembly. An extension plate for clamping the box is provided at the end of the base plate, with a motor connected to the box via a rotating shaft on the extension plate. A strip plate is provided inside the box, with a screw II screwed onto its side wall and connected to a bearing on one end face of the strip plate. A pressure sensor is provided on the other end face of the strip plate.
[0007] Preferably, the bottom of the base plate is provided with a support foot, and the top side of the base plate is provided with a protrusion for fixing the electric push rod.
[0008] Preferably, a collection box is provided at the bottom of one end of the box body and the extension plate.
[0009] Preferably, the mounting plate and the sealing end sidewall of the housing are respectively provided with screw holes for screwing into the corresponding screw I and screw II.
[0010] Preferably, the limiting plate is located on the top surface of the bottom plate on one side of the cutting blade assembly, the cutting blade assembly is located directly above the two sets of mounting plates, and the length of the cutting blade assembly is greater than the distance between the two sets of limiting plates.
[0011] Preferably, the opening of the L-shaped plate is oriented towards the cutting blade assembly, the width of the internal opening of the box is equal to the distance between the two sets of mounting plates, the bottom wall of the box opening is not higher than the top horizontal plane of the bottom plate, and the top wall of the box opening is not lower than the bottom horizontal plane of the horizontal end of the L-shaped plate.
[0012] Preferably, the pivot is located on the side wall of the box away from the box opening, and a support rod for supporting the bottom of the box opening is provided between the two sets of extension plates.
[0013] The beneficial effects of this invention are as follows: This invention drives the L-shaped plate to move via an electric push rod, which in turn moves the metal plate on the base plate, causing the end of the metal plate to slide into the box and stop moving after contacting the strip plate. Then, the hydraulic rod drives the cutting blade assembly to move down to cut the metal plate above the base plate, so that the product length meets the production requirements after cutting. At the same time, the length of the metal plate sliding into the box can be limited by adjusting the position of the strip plate, thereby enabling the cutting of products of various lengths. After cutting, the box is flipped by a motor to facilitate the discharge of the cut products from inside the box. Attached Figure Description

[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0019] A metal cutting device for an electrical bridging component includes a base plate 1 with supporting feet at the bottom, mounting plates 2 on both sides of the top of the base plate 1, and limiting plates 3 on both sides between the two sets of mounting plates 2. A screw rod I4 is screwed onto the mounting plate 2, and its end is connected to the corresponding limiting plate 3 via a bearing. The mounting plate 2 is provided with screw holes for screwing the screw rod I4.
[0020] An L-shaped plate 5 is provided on one side of the top of the base plate 1, located between two sets of limiting plates 3 and inverted. The L-shaped plate 5 is driven by an electric push rod 6. A protrusion is provided on one side of the top of the base plate 1 to fix the electric push rod 6. A frame 7 is provided on the other side of the top of the base plate 1. A cutting blade assembly 8 driven by a hydraulic rod 9 is provided inside the frame 7.
[0021] A flat box 10, on the same side as the cutting blade assembly 8, is provided on the outer side of the base plate 1. The opening of the box 10 faces the cutting blade assembly 8. An extension plate 11 for clamping the box 10 is provided at the end of the base plate 1. A motor 12 connected to the box 10 via a rotating shaft 12 is provided on the extension plate 11. A strip plate 14 is provided inside the box 10. A screw II 15, which is connected to a bearing on one end face of the strip plate 14, is screwed onto the side wall of the box 10. A screw hole for screwing the screw II 15 is provided on the sealed end side wall of the box 10. A pressure sensor 16 is provided on the other end face of the strip plate 14.
[0022] like Figure 1 , 2 As shown, a collection box 17 is provided at the bottom right end of the box body 10 and the extension plate 11.
[0023] like Figure 1 As shown, the limiting plate 3 is located on the top surface of the bottom plate 1 on one side of the cutting blade assembly 8, the cutting blade assembly 8 is located directly above the two sets of mounting plates 2, and the length of the cutting blade assembly 8 is greater than the distance between the two sets of limiting plates 3.
[0024] In this embodiment, the opening of the L-shaped plate 5 is set towards the cutting blade group 8. The width of the internal opening of the box body 10 is equal to the distance between the two sets of mounting plates 2. The bottom wall inside the opening of the box body 10 is not higher than the top horizontal plane of the bottom plate 1, and the top wall inside the opening of the box body 10 is not lower than the bottom horizontal plane of the horizontal end of the L-shaped plate 5.
[0025] like Figure 2 As shown, the rotating shaft 13 is set on the side wall of the box 10 at a distance from the opening of the box 10, and a support rod 18 is provided between the two sets of extension plates 11 to support the bottom of the opening end of the box 10, thereby improving the stability of the suspended end of the box 10.
[0026] The method of using this invention is as follows: The distance between the two sets of limiting plates 3 is adjusted according to the width of the metal plate. The steps are as follows: the screw I4 is rotated to rotate in the screw hole on the side wall of the mounting plate 2 and in the bearing on the back of the limiting plate 3, thereby driving the limiting plate 3 to move on the base plate 1, thereby expanding or reducing the distance between the two sets of limiting plates 3 so that the distance between them matches the width of the metal plate. Then, the metal plate is placed on the base plate 1 between the two sets of limiting plates 3, and the metal plate is moved to the left so that its left end slides into the opening of the L-shaped plate 5. The L-shaped plate 5 fixes the end of the metal plate and prevents it from moving up and down.
[0027] During cutting, the strip plate 14 can be moved according to the final cutting length of the product. The specific steps are as follows: rotate the screw II 15 to rotate it in the screw hole on the sealing end of the box and in the bearing on the back of the strip plate 14, thereby pushing the strip plate 14 to adjust its position within the box 10, so that the distance between the strip plate 14 and the cutting blade assembly 8 meets the production requirements. Then, the electric push rod 6 drives the metal plate above the base plate 1 to move to the right on the two sets of limit plates 3 through the L-shaped plate 5. Finally, the end of the metal plate slides into the box 10 and interacts with the strip plate 14 and the pressure sensor. After the pressure sensor 16 is pressed by the end of the metal plate, the electric push rod 6 stops working. At this time, the hydraulic rod 9 drives the cutting blade assembly 8 to move down to cut the metal plate. Most of the small pieces of metal plate obtained by cutting are located in the opening of the box 10. Then, the box 10 can be driven by the motor 12 and the rotating shaft 13 to rotate clockwise around the rotating shaft 13. Finally, the opening of the box 10 is turned downward so that the products inside can slide into the collection box 17 for collection. Then the box 10 is reset and the above steps are repeated to cut the metal plate.
[0028] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
