Description

Technical Field

[0001] This utility model relates to the field of metal product edge rolling technology, and in particular to an edge rolling device for metal product processing. Background Technology

[0002] Edge rolling equipment, commonly known as edge rolling machine or edge rolling press, is a type of mechanical equipment widely used in industrial production. Edge rolling equipment is required for edge rolling in the processing of metal products (cylinders).

[0003] A search revealed that patent CN220880091U discloses a crimping device for metal product processing; however, this crimping device has the following shortcomings in use:

[0004] During the edge-rolling process, the edge-rolling rod comes into contact with the product. The third motor rotates the base plate to roll the edge of the product. However, during the edge-rolling process, the edge-rolling rod and the product will rub against each other, which will generate a certain amount of heat. If the rolled edge is accidentally touched when the product is removed after the edge-rolling is finished, it can easily cause burns to the hands of the personnel, which is quite inconvenient. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where the edge-rolling rod is in contact with the product during the edge-rolling process, and the edge-rolling operation is carried out by a third motor driving the base plate to rotate. However, during the edge-rolling process, the edge-rolling rod and the product will rub against each other, which will generate a certain amount of heat. If the edge-rolled area is accidentally touched when the product is removed after the edge-rolling is completed, it can easily cause burns to the hands of the personnel, which is quite inconvenient. Therefore, this invention proposes an edge-rolling device for metal product processing.

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

[0007] A metal product processing edge-rolling device includes a support and an edge-rolling bar. A frame is welded to the top of the support. A second cylinder and a first cylinder for adjusting the edge-rolling bar are fixedly installed on the inner wall of the top of the frame. A fixed plate is fixedly installed on the telescopic part of the first cylinder. A conical head is rotatably connected to the bottom of the fixed plate. A rotating plate is rotatably connected to the top of the support, and the rotating plate is located directly below the conical head. A frame is fixedly installed on the telescopic part of the second cylinder. One side of the frame is slidably connected to the inner wall of one side of the frame. An electric push rod for adjusting the edge-rolling bar left and right is fixedly installed on the inner wall of one side of the frame. The telescopic part of the electric push rod passes through one side of the frame. A circular plate is fixedly installed on the telescopic part of the electric push rod. A rotating plate is rotatably connected to one side of the circular plate. A motor for driving the metal product to rotate is fixedly installed on the inner wall of the top of the support. The output end of the motor passes through the top of the support and is fixedly connected to the bottom of the rotating plate.

[0008] A clamping mechanism is installed on a rotating plate to clamp and fix metal products.

[0009] A fixing mechanism is installed on the circular plate to fix the edge-rolling bar;

[0010] The cooling mechanism is installed on the circular plate to cool down the metal products by blowing air during edge rolling.

[0011] In one possible design, the clamping mechanism includes four clamping plates and four U-shaped frames. A second slider is fixedly installed at the bottom of each of the four clamping plates. The top of the rotating plate has four second sliding grooves. The bottom of the second slider is slidably connected to the inner wall of the second sliding groove. The bottom of the four U-shaped frames is fixedly connected to the top of the four clamping plates respectively. The U-shaped frames and clamping plates are an integral structure. The same elastic sleeve is fitted on the four U-shaped frames. The bottom end of the conical head is inserted into the annular space formed by the four U-shaped frames.

[0012] In one possible design, the fixing mechanism includes a threaded rod and a nut. One end of the threaded rod is fixedly connected to one side of the rotating plate. The rolled edge bar has a circular hole adapted to the threaded rod. The rolled edge bar is sleeved on the threaded rod through the circular hole. The nut is threadedly connected to the threaded rod. The rolled edge bar is located between the rotating plate and the nut.

[0013] In one possible design, the cooling mechanism includes a support plate, a blower box, a fan, and a housing. The bottom of the support plate is fixedly connected to the top of the circular plate. One side of the blower box is fixedly connected to one side of the support plate. One side of the housing is fixedly connected to the other side of the support plate. The air outlet of the fan is fixedly connected to and communicates with one side of the housing. The bottom of the blower box has multiple air holes. The top of the housing is fixedly provided with an air pipe that communicates with the blower box. One end of the air pipe is fixedly connected to the top of the blower box.

[0014] In one possible design, both one side of the circular plate and one side of the rotating plate have insertion holes, and the same limiting bracket for preventing the rotating plate from rotating when the nut is turned is inserted into both insertion holes.

[0015] In one possible design, a first groove is provided on one inner wall of the frame to reduce friction caused by frame movement, and a first slider is fixedly provided on one side of the frame, with one side of the first slider slidably connected to the inner wall of the first groove.

[0016] In one possible design, multiple cooling rods are fixedly installed on the bottom inner wall of the housing to improve the cooling effect.

[0017] In this application, when installing the edge-rolling bar, the limiting bracket is inserted into the insertion holes of the round plate and the rotating plate, then the edge-rolling bar is sleeved on the threaded rod, then the nut is taken out and sleeved on the threaded rod, and rotated so that the rotating plate and the nut are tightly attached to the edge-rolling bar, thereby installing and fixing the edge-rolling bar and facilitating replacement.

[0018] In use, first remove the limiting brackets inserted into the holes of the circular plate and rotating plate. Connect the air and power sources to the first and second cylinders. Connect the power sources to the first motor, electric push rod, cooling rod, and fan. Connect the external controller to control the first cylinder, second cylinder, first motor, electric push rod, cooling rod, and fan. Place the metal product (cylindrical) to be rolled onto the rotating plate and fit it onto the four clamps. Start the cooling rod and the first cylinder. The extension and retraction of the first cylinder's telescopic part drives the movement of the fixed plate and the conical head. The device moves downwards and inserts into the space formed by the four clamping plates. The downward pressure of the conical head spreads the four clamping plates, ensuring they are tightly pressed against the metal product, thus clamping and fixing it in place. Then, the electric push rod is activated. The extension and retraction of the electric push rod's telescopic part moves the rotating plate, the edge-rolling rod, and the cooling mechanism, moving the edge-rolling rod above the top edge of the metal product. Subsequently, the second cylinder is activated. The extension and retraction of the second cylinder's telescopic part moves the frame, which in turn moves the electric push rod, the edge-rolling rod, and the cooling mechanism. Move the device to a suitable height, start the motor and fan. The motor output drives the rotating plate and the metal product on it to start rotating. While the metal product is rotating, the second cylinder gradually lowers the curling rod, making it fit against the top of the metal product. Through the downward pressure of the curling rod and the rotation of the metal product, the edge is curled. During the curling process, the fan generates airflow, which is cooled by the cooling rod inside the box and blown onto the curled part of the metal product through multiple air holes at the bottom of the air box. This cools the curled part of the metal product, reducing the possibility of burns to the hands. The cooling rod effectively improves the cooling effect of the curled part of the metal product. After the curling is completed, the first cylinder lifts the conical head. During the lifting process, the four clamps return to their initial position through the elastic sleeve. The elastic sleeve can be an elastic band, rubber band, elastic belt, or metal spring. Then, the second cylinder raises the curling rod, and the metal product can be removed. The power supply for the cooling rod can be installed through a small hole in the box for easy installation of the power cord.

[0019] The beneficial effects of this utility model are as follows:

[0020] In this utility model, the metal product processing edge-rolling device places the metal product (cylindrical shape) to be rolled onto the rotating plate and sleeves it on four clamping plates through the clamping mechanism. The extension and retraction of the first cylinder extension and retraction part drives the movement of the fixed plate and the conical head. The conical head moves downward and inserts into the space formed by the four clamping plates. The downward pressure of the conical head opens the four clamping plates, so that the clamping plates are close to the metal product, thereby clamping and fixing the metal product.

[0021] In this utility model, the edge-rolling equipment for metal product processing uses a fixing mechanism to fit the edge-rolling rod onto the threaded rod. Then, a nut is taken out and fitted onto the threaded rod, and rotated to make the rotating plate and the nut tightly adhere to the edge-rolling rod, thereby allowing the edge-rolling rod to be installed and fixed, and easy to replace.

[0022] In this utility model, the edge-rolling equipment for metal product processing uses a cooling mechanism. The start of the fan generates airflow, which is cooled by the cooling rod inside the box. The cooled air is then blown onto the edge-rolling part of the metal product through multiple air holes at the bottom of the air box, thereby cooling the edge-rolling part of the metal product and reducing the possibility of burns to the hands of personnel.

[0023] In this invention, the clamping mechanism can clamp and fix the metal product, the fixing mechanism can install and fix the rolled edge rod and make it easy to replace, and the cooling mechanism can blow air to cool down the rolled edge of the metal product, reducing the possibility of burns to people's hands.

[0033] The telescopic part of the second cylinder 4 is fixedly connected to the frame 12. One side of the frame 12 is slidably connected to the inner wall of one side of the frame 2.
