Description

Technical Field

[0001] This utility model relates to the field of metal bending technology, and in particular to a seamless bending device for metal parts that is easy to position. Background Technology

[0002] A metal part seamless bending device is a specialized equipment or technical system used for bending metal sheets or profiles. Its core objective is to avoid or minimize visible defects such as indentations, scratches, deformations or cracks on the metal surface during the bending process, while maintaining the geometric accuracy and appearance quality after bending.

[0003] Existing seamless bending devices for metal parts lack a positioning structure, resulting in inaccurate positioning of the metal parts before bending. Inaccurate positioning causes uneven stress on the metal parts during bending, leading to structural deformation. The deformed metal parts may not meet the usage requirements or may even become scrap. Utility Model Content

[0004] The purpose of this invention is to provide a seamless bending device for metal parts that facilitates positioning. This device enables easy positioning of metal parts, thus solving the problem of inconvenient positioning of metal parts in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A seamless bending device for easily positioned metal parts includes a base with two vertical plates fixedly connected to its upper end. Each vertical plate has a positioning groove at its upper end, and multiple electromagnets are fixedly connected to the bottom of the positioning groove. A pressure sensor is also fixedly connected to the bottom of the positioning groove and electrically connected to the electromagnets. A bending seat is fixedly connected to the upper end of the base, located between the two vertical plates. A movable frame is slidably mounted on the upper end of the base, with movable plates slidably connected between the inner walls of both sides of the movable frame. A bending plate is fixedly connected to the lower end of each movable plate.

[0007] Preferably, the base has grooves on both sides, and the grooves are slidably connected to the ends of the movable frame.

[0008] Preferably, a screw is rotatably connected inside one of the grooves, and the screw is threadedly connected to the movable frame.

[0009] Preferably, a motor is fixedly connected inside the side wall of the base, and the output end of the motor is fixedly connected to the end of the screw via a coupling.

[0010] Preferably, the lower end of the base is fixedly connected to a plurality of base columns, which are distributed in a rectangular array.

[0011] Preferably, a plurality of hydraulic cylinders are fixedly connected to the upper end of the movable frame, the plurality of hydraulic cylinders are equidistantly arranged, and the output end of the hydraulic cylinders is fixedly connected to the upper end of the movable plate.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The metal part is placed inside two positioning slots. The positioning slots provide a clear placement position and boundary limit for the metal part. Then, the lower end of the metal part is magnetically attracted and fixed by the magnetic force generated by the upper end of the electromagnet, which further enhances the positioning stability of the metal part on the vertical plate. The attraction of the electromagnet can firmly fix the metal part in its original position and prevent it from moving due to force, ensuring that the bending position is always kept in the predetermined middle position, which greatly improves the bending accuracy.

[0014] 2. When the pressure sensor detects that the pressure on the metal part reaches the preset value, the pressure sensor controls the electromagnet to de-energize, and the magnetic force at the upper end of the electromagnet disappears. Then, the movable plate drives the bending plate to slide downward continuously. Through the cooperation between the bending plate and the bending seat, the metal part is bent without leaving marks. This allows the operator to operate and control the part only in a safe area without having to approach the bending area, reducing the possibility of injury and improving the safety of operation.

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-5 A seamless bending device for easily positioned metal parts includes a base 001, with two vertical plates 104 fixedly connected to the upper end of the base 001. A positioning groove 105 is provided at the upper end of each vertical plate 104, and multiple electromagnets 106 are fixedly connected to the bottom of the positioning groove 105. A pressure sensor 107 is fixedly connected to the bottom of the positioning groove 105 and is electrically connected to the electromagnets 106. A bending seat 108 is fixedly connected to the upper end of the base 001, located between the two vertical plates 104. A movable frame 002 is also included. 02 is slidably mounted on the upper end of the base 001. A movable plate 202 is slidably connected between the inner walls of both sides of the movable frame 002. A bending plate 203 is fixedly connected to the lower end of the movable plate 202. The surface of the bending plate 203 and the inside of the bending seat 108 are coated with molybdenum disulfide. When it is necessary to bend the middle section of the plate-shaped iron metal part, the operator places the plate-shaped iron metal part on the upper end of the two vertical plates 104. At the same time, the metal part is located inside the two positioning grooves 105. The lower end of the metal part is in contact with the upper end of the electromagnet 106 and the upper end of the pressure sensor 107. The operator... The operator manually activates electromagnet 106, generating magnetic force at its upper end to magnetically attract and fix the lower end of the metal part, thus securing and positioning it. Simultaneously, pressure sensor 107 monitors the pressure on the metal part in real time. The lower end of the metal part is in contact with the upper end of bending seat 108. After the metal part is fixed in position, movable frame 002, via movable plate 202, drives bending plate 203 to slide laterally, moving bending plate 203 directly above bending seat 108. Then, movable plate 202 drives bending plate 203 to slide downwards, causing bending... The lower end of plate 203 contacts the upper end of the metal part and applies pressure to the metal part. When the pressure sensor 107 detects that the pressure on the metal part reaches the preset value, the pressure sensor 107 controls the electromagnet 106 to be de-energized. The magnetic force at the upper end of the electromagnet 106 disappears. Then, the movable plate 202 drives the bending plate 203 to slide downward continuously. Through the cooperation between the bending plate 203 and the bending seat 108, and through the lubrication performance of molybdenum disulfide, the two ends of the metal part are released from the fixed constraint of the positioning groove 105, and the metal part is bent without marks.

[0023] The base 001 has grooves 101 on both sides. The grooves 101 are slidably connected to the end of the movable frame 002. The grooves 101 guide and limit the lateral sliding of the movable frame 002.

[0024] One of the grooves 101 is rotatably connected to a screw 102, which is threadedly connected to the movable frame 002. When the screw 102 rotates, the movable frame 002 moves laterally through the threaded engagement between the screw 102 and the movable frame 002.

[0025] A motor 103 is fixedly connected inside the side wall of the base 001. The output end of the motor 103 is fixedly connected to the end of the screw 102 through a coupling. The output end of the motor 103 drives the screw 102 to rotate. The motor 103 is manually switched on and off by the operator.

[0026] The lower end of the base 001 is fixedly connected to multiple base columns 109, which are distributed in a rectangular array to support the base 001.

[0027] Multiple hydraulic cylinders 201 are fixedly connected to the upper end of the movable frame 002. The multiple hydraulic cylinders 201 are equidistantly arranged. The output end of the hydraulic cylinder 201 is fixedly connected to the upper end of the movable plate 202. The hydraulic cylinder 201 is used in conjunction with an external hydraulic pump. The output end of the hydraulic cylinder 201 pushes or pulls the movable plate 202 to slide up and down.

[0028] In this utility model, when it is necessary to bend the middle section of a plate-shaped iron metal part, the operator places the plate-shaped iron metal part on the upper end of two vertical plates 104, while the metal part is located inside two positioning grooves 105. The lower end of the metal part is in contact with the upper end of the electromagnet 106 and the upper end of the pressure sensor 107. The operator manually turns on the electromagnet 106, and the upper end of the electromagnet 106 generates magnetic force to magnetically attract and fix the lower end of the metal part, thereby fixing and positioning the metal part. At the same time, the pressure sensor 107 monitors the pressure on the metal part in real time, and the lower end of the metal part is in contact with the upper end of the bending seat 108.

[0029] After the metal parts are fixed in place, the screw 102 is driven to rotate by the output end of the motor 103. Through the threaded engagement between the screw 102 and the movable frame 002, the movable frame 002 drives the bending plate 203 to slide laterally via the movable plate 202. The side wall of the movable frame 002 is in contact with the inner right wall of the groove 101. The bending plate 203 moves to directly above the bending seat 108, and then the output end of the hydraulic cylinder 201 pushes the movable plate 202 to slide downward. The movable plate 202 drives the bending plate 203 to slide downward, so that the bending plate 203... The lower end contacts the upper end of the metal part and applies pressure to the metal part. When the pressure sensor 107 detects that the pressure on the metal part reaches the preset value, the pressure sensor 107 controls the electromagnet 106 to be de-energized. The magnetic force at the upper end of the electromagnet 106 disappears. Then the movable plate 202 drives the bending plate 203 to slide downward continuously. Through the cooperation between the bending plate 203 and the bending seat 108, and through the lubrication performance of molybdenum disulfide, the two ends of the metal part are released from the fixed constraint of the positioning groove 105, and the metal part is bent without marks.

[0030] When it is necessary to remove the bent metal part, the output end of the hydraulic cylinder 201 pulls the movable plate 202 upward to slide it, so that the bending plate 203 is separated from the metal part. Then, the output end of the motor 103 drives the screw 102 to rotate. Through the threaded engagement between the screw 102 and the movable frame 002, the movable frame 002 drives the bending plate 203 to slide laterally through the movable plate 202. The side wall of the movable frame 002 fits against the inner wall of the left side of the groove 101, and the bending plate 203 moves laterally out from above the bending seat 108. Then, the operator can take out the bent metal.

[0031] 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.
