Description

Technical Field

[0001] This utility model relates to the field of flanging and bending equipment technology, and in particular to a flanging machine for metal cabinet panel production. Background Technology

[0002] A distribution cabinet is a general term for a motor control center. A distribution cabinet consists of a cabinet body, busbars, circuit breakers, fuses, indicator lights, meters, ammeters, voltmeters, control buttons, power capacitors, power factor controllers, current-limiting reactors, contactors, and other components. The cabinet body is mostly assembled from cabinet panels.

[0003] Utility model CN216324340U discloses a device for bending and folding distribution cabinet panels. However, existing devices rely on manual panel support, which causes the panels to warp during bending. This warping leads to misalignment during bending and can injure workers, posing a significant safety hazard. The proposed solution includes a base, a hydraulic press, and a screw-slide-type clamping and limiting mechanism. The hydraulic press is mounted above the base, and a bending blade is installed below it. The screw-slide-type clamping and limiting mechanism is mounted on one side of the base. This novel design replaces manual labor with a mechanical structure, effectively preventing panel misalignment during bending, resulting in better bending performance. It can clamp and fix panels of different specifications, further preventing injuries to workers and effectively eliminating safety hazards.

[0004] In the above solution, the first and second clamping plates require adjustment with nuts each time they are used, which is slow; the first and second support rods extend far out but lack a supporting structure, resulting in poor stability when supporting the plates; the first and second support rods cannot be retracted, which affects the normal operation of the staff when they are not in use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the support rod in the existing cabinet panel flanging and bending device cannot be retracted when not in use, and to propose a flanging machine for metal cabinet panel production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flanging machine for producing metal cabinet panels includes a flanging machine body and a bending knife disposed in front of the flanging machine body. A foldable support mechanism is disposed below the bending knife. The support mechanism includes a first support frame and a telescopic unit. The top of the first support frame is hinged to the flanging machine body, and the two ends of the telescopic unit are respectively hinged to the flanging machine body and the lower part of the first support frame.

[0008] Furthermore, the first support frame includes a first frame and a first longitudinal beam. The top of the first frame is hinged to the body of the flanging machine, the lower part of the first frame is hinged to the telescopic unit, and the first longitudinal beam is provided inside the first frame along the direction of cabinet panel entry and exit.

[0009] Furthermore, multiple first longitudinal beams are spaced apart inside the first frame along a direction perpendicular to the cabinet panel's entry and exit.

[0010] Furthermore, a first through hole is provided on the first longitudinal beam, and a clamping mechanism is detachably inserted inside the first through hole.

[0011] Furthermore, the clamping mechanism includes a plug rod passing through the first through hole and a pressure rod pressing on the cabinet plate, with the ends of the plug rod and the pressure rod connected by a connecting block.

[0012] Furthermore, the pressure rod is provided with a plurality of elastic rollers at intervals.

[0013] Furthermore, the support mechanism also includes a second support frame that is pulled out and installed at the bottom of the first support frame.

[0014] Furthermore, the second support frame includes a second frame, a second longitudinal beam, and support legs. The support legs are rotatably arranged inside the second frame, and the second frame and the first support frame are slidably connected through the second longitudinal beam.

[0015] Furthermore, the second longitudinal beam is slidably mounted on the first support frame along the in-and-out direction of the cabinet panel. The first support frame has a pin hole corresponding to the second longitudinal beam, and a pin is detachably installed inside the pin hole.

[0016] Furthermore, an anti-slip layer is provided on the inner wall of the second frame.

[0017] Compared with the prior art, this utility model provides a flanging machine for metal cabinet panel production, which has the following beneficial effects:

[0018] This utility model discloses a flanging machine for producing metal cabinet panels. In use, the telescopic unit is extended, driving the support mechanism to rotate to a horizontal state. Then, the metal cabinet panel to be processed is placed on the support mechanism, and the panel is flanged and bent by a bending knife. When the support mechanism is not needed, the telescopic unit is retracted, driving the telescopic mechanism to rotate to a vertical state, fitting against the front end of the flanging machine body. This avoids obstructing the normal work of the workers. Compared with the prior art, it is more flexible and practical.

[0019] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-5 The present invention relates to a metal cabinet panel production flanging machine, comprising a flanging machine body 1 and a bending knife 2 installed in the middle of the front of the flanging machine body 1. A foldable support mechanism 3 is installed below the bending knife 2. The support mechanism 3 is installed in the lower part of the front end face of the flanging machine body 1 and fits against the front end face of the flanging machine body 1.

[0029] The support mechanism 3 includes a first support frame 4 and a telescopic unit 7. The first support frame 4 is a rectangular frame structure, and the length of the first support frame 4 corresponds to the width of the bending blade 2.

[0030] The top of the first support frame 4 is hinged to the body 1 of the flanging machine, so that the first support frame 4 can rotate forward or downward around its own top crossbeam. The two ends of the telescopic unit 7 are respectively hinged to the lower part of the body 1 of the flanging machine and the first support frame 4. The telescopic unit 7 can be a hydraulic cylinder or an electric cylinder, used to push the first support frame 4 to rotate to a horizontal state and support the first support frame 4 to maintain a horizontal state, so that the metal cabinet plate to be processed can be placed on the first support frame 4.

[0031] The first support frame 4 includes a first frame 401 and a first longitudinal beam 402. The top crossbeam of the first frame 401 is hinged to the flanging machine body 1, and the lower part of the first frame 401 is hinged to the telescopic unit 7. The first longitudinal beam 402 is fixedly connected inside the first frame 401 along the direction of cabinet panel entry and exit. The first longitudinal beam 402 is used to support the metal cabinet panel from the middle of the first frame 401.

[0032] Since the sheet metal used for metal cabinet panels is generally thin, the first longitudinal beam 402 can prevent the metal cabinet panel from falling towards the middle when placed on the first frame 401. Compared with the existing technology which only has a first support rod and a second support rod, this is more conducive to the flat placement of the water inlet cabinet panel.

[0033] Multiple first longitudinal beams 402 are installed at intervals inside the first frame 401 along the direction perpendicular to the entry and exit of the cabinet panels. Their function is to support metal cabinet panels of different widths and, in conjunction with the clamping mechanism, clamp the metal cabinet panels of different widths.

[0034] A first through hole 403 is machined on the first longitudinal beam 402. The first through hole 403 is machined in a direction perpendicular to the direction of the metal cabinet panel's entry and exit (parallel to the width direction of the bending knife 2). A clamping mechanism 6 is detachably installed inside the first through hole 403. The clamping mechanism 6 restricts the metal cabinet panel on the first support frame 4 to prevent the metal cabinet panel from shifting or tilting.

[0035] Specifically, the clamping mechanism 6 includes an insert rod 601 that passes through the first through hole 403 and a pressure rod 603 that presses against the cabinet plate. The ends of the insert rod 601 and the pressure rod 603 are connected by a connecting block 602. When the insert rod 601 is inserted into the first through hole 403, a gap is left between the pressure rod 603 and the front of the first longitudinal beam 402. In use, the metal cabinet plate is located in this gap.

[0036] The insertion rod 601, connecting block 602, and pressure rod 603 form a U-shaped structure. In use, after the metal cabinet plate is laid on the first support frame 4, the insertion rod 601 is inserted into the first through hole 403 from both sides of the metal cabinet plate towards the middle, so that the pressure rod 603 is located on the metal cabinet plate, limiting the metal cabinet plate and preventing the metal cabinet plate from tilting up significantly.

[0037] Multiple elastic rollers 604 are installed at intervals on the pressure rod 603. The rollers 604 can be rubber wheels. The rollers 604 roll along the in-and-out direction of the metal cabinet panel, which facilitates the adjustment of the position of the metal cabinet panel and changes the length of the metal cabinet panel entering the bending knife 2.

[0038] The support mechanism 3 also includes a second support frame 5 that is pulled out and installed at the bottom of the first support frame 4. The second support frame 5 is installed on the first support frame 4 in a pull-out connection manner. When the length of the first support frame 4 is insufficient, the second support frame 5 is pulled out to help increase the length of the first support frame 4, so as to facilitate the support of longer metal cabinet panels.

[0039] The second support frame 5 includes a second frame 501, a second longitudinal beam 502, and support legs 503. The second frame 501 is also a rectangular frame structure with a smaller length, mainly used to install the support legs 503. The bottom of the support legs 503 has a rounded end face. The support legs 503 are mounted inside the second frame 501. When the first support frame 4 rotates to a horizontal position, the second frame 501 is pulled forward and extended to a suitable length. Then, the support legs 503 are rotated downward so that they support the ground. The two support legs 503 provide support to the second support frame 5 from positions near both sides, avoiding the situation in the prior art where the first and second support rods lack supporting structures, thus affecting their supporting effect.

[0040] The second frame 501 is slidably connected to the first support frame 4 via a second longitudinal beam 502. The second longitudinal beam 502 is arranged parallel to the first longitudinal beam 402. A third through hole is machined on the crossbeam of the first frame 401 on the side away from the bending knife 2. The size of the third through hole corresponds to the second longitudinal beam 502. The second longitudinal beam 502 is movably slidably inserted into the third through hole. One end of the second longitudinal beam 502 located on the outside of the first support frame 4 is connected to the second frame 501. A stop is installed on the end of the second longitudinal beam 502 located on the inside of the first support frame 4 to prevent the second longitudinal beam 502 from being pulled out and separated from the third through hole.

[0041] There are multiple second longitudinal beams 502, which are arranged at intervals. This serves two purposes: first, it can enhance the structural strength of the second support frame 5; second, it can also provide support for the metal cabinet panel from the middle position.

[0042] The second longitudinal beam 502 is slidably mounted on the first support frame 4 along the inlet and outlet direction of the cabinet panel. The first support frame 4 is machined with a pin hole 505 corresponding to the second longitudinal beam 502. The pin hole 505 passes through the side wall on the front side of both the first support frame 4 and the second longitudinal beam 502. A pin 504 is detachably installed inside the pin hole 505. Its function is that after each use, when the second support frame 5 is retracted into the first support frame 4, the pin 504 is inserted into the pin hole 505 to prevent the second support frame 5 from automatically sliding out of the first support frame 4 when the first support frame 4 is retracted.

[0043] An anti-slip layer is installed on the inner wall of the second frame 501. The anti-slip layer can be a rubber pad. After the support leg 503 is retracted into the second frame 501, the outer wall of the support leg 503 and the inner wall of the second frame 501 are provided with sufficient friction through the rubber pad to prevent the support leg 503 from automatically rotating out of the inside of the second frame 501 during the opening of the second support frame 5.

[0044] Working principle: When in use, the telescopic unit 7 is extended, which drives the first support frame 4 to rotate to a horizontal state. The metal cabinet panel to be processed is placed on the first support frame 4. Then, the clamping mechanism 6 is used to clamp the metal cabinet panel from both sides to prevent the metal cabinet panel from shifting and tilting. Finally, the edge of the metal cabinet panel is bent by the bending knife 2.

[0045] When the length of the first support frame 4 is insufficient, the pin 504 is pulled out, and the second frame 501 is pulled outward. After reaching the appropriate length, the support leg 503 is rotated downward to a vertical position to support the second support frame 5, which is used to further support the metal cabinet panel.

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.
