Description

Technical Field

[0001] The utility model relates to the technical field of workpiece bending and positioning, in particular to an auxiliary positioning mechanism for a bending machine. Background Art

[0002] A bending machine is a mechanical device used for processing metal sheets, profiles and other materials. It uses a bending die to bend the material. It is widely used in the fields of automobiles, aviation, elevators, doors, etc. The bending machine mainly drives the bending die through a hydraulic system or a mechanical transmission system to work. In the bending process, the positioning of the workpiece is an important link. In order to ensure the accurate position of the workpiece during the bending process, a positioning block is usually used to position the workpiece.

[0003] However, the existing structure for positioning the workpiece has a shortcoming, that is, after the workpiece is bent, the positioning block cannot clean the waste chips in the bending groove, which will affect the quality of subsequent workpiece bending.

[0004] In order to solve the above problems, the present application proposes an auxiliary positioning mechanism for a bending machine. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes an auxiliary positioning mechanism for a bending machine.

[0006] The utility model provides an auxiliary positioning mechanism for a bending machine, comprising a bending seat and a bending groove provided on the bending seat;

[0007] The bending seat is provided with two fixed blocks located on one side of the bending groove, and a gas cylinder is installed on the side away from the two fixed blocks, and a piston is installed in the two gas cylinders, and an elastic limiter is installed on the opposite side of the two fixed blocks, and the two elastic limiters are respectively slidably inserted into the two gas cylinders and connected to the corresponding pistons;

[0008] Chip blowing pieces are installed at both ends of the bending groove, and the two chip blowing pieces are respectively connected to two air cylinders.

[0009] Preferably, the piston member comprises a piston body, the piston body is slidably arranged in the air cylinder, a pull rod is connected to the piston body and slides through one end of the air cylinder away from the fixed block, and a handle plate is installed at the end of the pull rod away from the piston body.

[0010] Preferably, the elastic limit member includes a limit rod, and the two limit rods respectively slide through the two fixed blocks and the two air cylinders and are connected to the corresponding piston bodies. Limit plates are installed on the opposite ends of the two limit rods. The limit rod is sleeved with a spring located between the fixed block and the limit plate, and the two ends of the spring are respectively connected to the fixed block and the limit plate.

[0011] Preferably, the chip blowing component includes a shaft cylinder, and the two shaft cylinders are respectively installed at the two ends of the bending groove, and a through air blowing channel is opened in the two shaft cylinders. The two shaft cylinders are connected with a conducting pipe at one end away from each other, and the two conducting pipes are respectively connected with the two air blowing channels, and the ends of the two conducting pipes away from the shaft cylinders are respectively connected with the ends of the two air cylinders close to the fixed block.

[0012] Preferably, a material dropping channel communicating with the bending groove is provided at the bottom of the bending seat.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] By means of the arranged air cylinder, piston part, elastic limiting part and chip blowing part, the piston parts on the two air cylinders can be pulled outward, so that the two elastic limiting parts move away from each other. At the same time, external air enters the air cylinder through the chip blowing part, and then the workpiece to be bent is covered on the bending groove and placed between the two elastic limiting parts. The workpiece is clamped by the two elastic limiting parts, and then the workpiece can be stamped and bent by the bending machine. After the workpiece is stamped and bent, the workpiece can be taken down. After the elastic limiting part loses its restriction, the piston part returns to its original position under the elastic force, thereby pushing the air entering the air cylinder into the chip blowing part, and then the waste chips in the bending groove are blown by the chip blowing part. After the workpiece is bent, this structure can push the gas in the air cylinder into the chip blowing part through the returning action of the piston part, and blow the bending groove, which can quickly clean up the waste chips, so that the bending process of the next workpiece can be carried out quickly, thereby improving production efficiency.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] like Figure 1 and Figure 2 As shown, the utility model provides an auxiliary positioning mechanism for a bending machine, comprising a bending seat 1 and a bending groove 2 provided on the bending seat 1;

[0020] In this embodiment, two fixing blocks 3 located on one side of the bending groove 2 are installed on the bending seat 1, and gas cylinders 4 are installed on the sides of the two fixing blocks 3 away from each other, and piston members 5 are installed in the two gas cylinders 4. The piston member 5 includes a piston body 51, which is slidably arranged in the gas cylinder 4, and a pull rod 52 is connected to the piston body 51, which slides through the end of the gas cylinder 4 away from the fixing block 3, and a handle plate 53 is installed on the end of the pull rod 52 away from the piston body 51.

[0021] In this embodiment, elastic stoppers 6 are installed on opposite sides of the two fixed blocks 3, and the two elastic stoppers 6 are respectively inserted into the two gas cylinders 4 and connected to the corresponding piston members 5. The elastic stoppers 6 include stopper rods 61, and the two stopper rods 61 respectively slide through the two fixed blocks 3 and the two gas cylinders 4 and are connected to the corresponding piston bodies 51. The two stopper rods 61 are installed with stopper plates 62 at opposite ends, and the stopper rods 61 are sleeved with springs 63 located between the fixed blocks 3 and the stopper plates 62, and the two ends of the springs 63 are respectively connected to the fixed blocks 3 and the stopper plates 62.

[0022] In this embodiment, a chip blowing member 7 is installed at both ends of the bending groove 2, and the two chip blowing members 7 are respectively connected to the two air cylinders 4. The chip blowing member 7 includes a shaft cylinder 71, and the two shaft cylinders 71 are respectively installed at the two ends of the bending groove 2, and a through air blowing channel is opened in the two shaft cylinders 71. The two ends of the two shaft cylinders 71 are connected to a conducting tube 72, and the two conducting tubes 72 are respectively connected to the two air blowing channels, and the ends of the two conducting tubes 72 away from the shaft cylinder 71 are respectively connected to the ends of the two air cylinders 4 close to the fixed block 3.

[0023] It should be noted that in order to clean the waste chips in the bending groove 2 after the workpiece is bent, the pull rod 52 can be pulled outward by the handle plate 53 to make the piston body 51 move in the air cylinder 4, and the two limit rods 61 respectively enter the corresponding air cylinder 4, so that the two limit plates 62 are separated from each other, and the spring 63 between the fixed block 3 and the limit plate 62 is compressed. When the piston body 51 moves outward, external air can enter the air cylinder 4 through the air blowing channel and the guide pipe 72 opened in the shaft cylinder 71, and then the workpiece to be bent is covered on the bending groove 2 and placed between the two limit plates 62. The workpiece is clamped by the two limit plates 62, and then the workpiece can be stamped and bent by the bending machine. After the workpiece is stamped and bent, the workpiece can be taken down. After the spring 63 loses its restriction, the two limit plates 62 are pushed back to their original positions under the elastic force, and the piston body 51 connected to the limit rod 61 also returns to its original position. During the return movement of the piston body 51 in the air cylinder 4, the air entering therein is discharged along the guide pipe 72 and the air blowing channel opened in the shaft cylinder 71, and then the waste chips in the bending groove 2 are blown by the air discharged from the shaft cylinder 71. After the workpiece is bent, this structure can push the gas in the air cylinder 4 into the chip blowing part 7 through the return action of the piston part 5, and blow the bending groove 2, so as to quickly clean up the waste chips, so that the bending process of the next workpiece can be carried out quickly, thereby improving production efficiency.

[0024] In a specific embodiment, a material dropping channel communicating with the bending groove 2 is provided at the bottom of the bending seat 1 .

[0025] It should be noted that the provided blanking channel facilitates the discharge of waste chips in the bending groove 2 .
