Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a novel segmented bending machine. Background Technology

[0002] A bending machine is a machine that can bend thin plates. It is an important processing equipment in the sheet metal industry and can press steel plates into parts of various shapes according to requirements.

[0003] In response, Chinese patent application number CN202223082151.5 discloses a novel segmented bending machine. The bending module is installed on the inner wall of the machine body for bending thin plates. It includes a first telescopic rod symmetrically fixed on the top wall of the main module, a fixing plate whose two ends are fixedly connected to the ends of the opposite first telescopic rod, a main shaft whose two ends are fixedly connected to the fixing plates on both sides, multiple bearings fixedly sleeved on the main shaft, multiple annular parts fixedly sleeved on the bearings, a mounting frame fixed in a ring array on the outer surface of the annular parts, a drive assembly installed on one side of the annular parts, and a bending tool fixed on the mounting frame. The first telescopic rod is fixed on the inner wall of the machine body for installing the fixing plate and driving the fixing plate to move up and down. The fixing plate is used to install the main shaft and drive the main shaft to move. The main shaft is used to install the bearings and the annular parts. This novel segmented bending machine has the advantages of quick bending tool replacement and convenient material loading.

[0004] This bending machine features a rotatable annular component that allows adjustment of the angles of multiple bending blades, facilitating the use of the corresponding blades to process objects. However, when bending objects, the entire annular component needs to be brought downwards towards the object, and the bending blades exposed on the front and rear surfaces of the annular component will obstruct the object, thus limiting the bending space and compromising the bending effect, which in turn affects the user experience of the device.

[0005] Therefore, in order to solve the above problems, a new type of segmented bending machine is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a novel segmented bending machine to solve the problem mentioned in the background art that the existing bending machine can adjust the angle of multiple sets of bending blades by setting a rotatable ring component, which is convenient for using the corresponding bending blades to process objects. However, when the bending blades are bending the objects, the entire ring component needs to be brought downwards and close to the objects. The bending blades exposed on the front and rear surfaces of the ring component will block the objects, thus obstructing the bending space of the objects and failing to guarantee the bending effect of the objects, which affects the user experience of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel segmented bending machine, comprising: a machine body, wherein a lower die is mounted on the top surface of the machine body;

[0008] An adjustment structure is installed on the inner side of the machine body. The adjustment structure includes a fixed cylinder, which is movably mounted on the inner wall of the machine body via a bearing. A through groove is opened on the surface of the fixed cylinder, and a movable block is movably installed on the inner side of the through groove. A slot is opened on one end of the movable block, and a bending knife is fixedly connected to the other end of the movable block. A guide rod is fixedly installed on the inner wall of the fixed cylinder, and a spring is sleeved on the outer side of the guide rod. A worm gear is fixedly connected to the left end of the fixed cylinder. A motor is installed on the left side wall of the machine body, and a worm is fixedly connected to the output end of the motor.

[0009] The machine body is equipped with a pushing structure, which includes a fixed block. The fixed block is fixedly installed on the left and right side walls of the machine body. A fixed frame is fixedly connected to the end of the fixed block, and a hydraulic cylinder is installed on the bottom surface of the middle part of the fixed frame.

[0010] Preferably, the bending blade is located outside the fixed cylinder, the two ends of the movable block are sleeved on the outside of the guide rod, and the two ends of the spring are fixedly connected to the fixed cylinder and the guide rod respectively.

[0011] Preferably, the worm gear meshes with a worm wheel.

[0012] Preferably, the fixing frame passes through the fixing cylinder, the hydraulic cylinder is installed vertically, and the hydraulic cylinder corresponds vertically to the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the movable block set in this utility model can extend and retract on the surface of the fixed cylinder, and when bending objects, the bending knife used can extend from the bottom surface of the fixed cylinder, keeping the position and height of the fixed cylinder unchanged, ensuring that the object can be fully bent with the cooperation of the bending knife and the lower die, improving the processing effect of the object, and ensuring the user experience of the device.

[0014] This invention features an adjustment and a pushing structure. When the motor is started, it drives a worm gear to rotate. The worm gear meshes with a worm wheel, and the rotation of the worm gear, in turn, drives the fixed cylinder to rotate. The fixed cylinder rotates within the machine body, causing the inner bending blades to adjust their angle. This allows the corresponding bending blade to be positioned below the fixed cylinder according to usage requirements. When an object is placed on the top surface of the lower die, the hydraulic cylinder is activated. The cylinder extends and inserts its extended end into a slot on the surface of a set of movable blocks located directly below the fixed cylinder. This pushes the movable blocks downwards, causing them to move downwards outside the guide rod and compress a spring. The movable blocks then move within the through slot, causing the corresponding bending blade to descend and approach the lower die. At this point, the fixed cylinder is in a fixed position. Therefore, the bending blades located on the front and rear sides of the fixed cylinder will not obstruct the bending of the object, ensuring that the object is fully bent with the cooperation of the bending blades and the lower die. This improves the processing effect and enhances the user experience of the device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a novel segmented bending machine:

[0022] The body 1, lower mold 11, motor 29 and hydraulic cylinder 33 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A novel segmented bending machine includes: a machine body 1, on the top surface of which a lower die 11 is mounted;

[0024] An adjustment structure 2 is installed on the inner side of the machine body 1. The adjustment structure 2 includes a fixed cylinder 21, which is movably installed on the inner wall of the machine body 1 via a bearing. A through groove 22 is opened on the surface of the fixed cylinder 21. A movable block 23 is movably installed on the inner side of the through groove 22. A slot 24 is opened on one end of the movable block 23. A bending knife 25 is fixedly connected to the other end of the movable block 23. A guide rod 26 is fixedly installed on the inner wall of the fixed cylinder 21. A spring 27 is sleeved on the outer side of the guide rod 26. A worm gear 28 is fixedly connected to the left end of the fixed cylinder 21. A motor 29 is installed on the left side wall of the machine body 1. A worm 210 is fixedly connected to the output end of the motor 29. The movable block 23 can extend and retract on the surface of the fixed cylinder 21. When bending objects, the bending knife 25 can extend from the bottom surface of the fixed cylinder 21, keeping the position and height of the fixed cylinder 21 unchanged. This ensures that the object can be fully bent with the cooperation of the bending knife 25 and the lower die 11, improving the processing effect of the object and ensuring the user experience of the device.

[0025] A pushing structure 3 is installed on the body 1. The pushing structure 3 includes a fixing block 31, which is fixedly installed on the left and right side walls of the body 1. A fixing frame 32 is fixedly connected to the end of the fixing block 31, and a hydraulic cylinder 33 is installed on the bottom surface of the middle part of the fixing frame 32.

[0026] Furthermore, the bending blade 25 is located outside the fixed cylinder 21, and the two ends of the movable block 23 are sleeved on the outside of the guide rod 26. The two ends of the spring 27 are fixedly connected to the fixed cylinder 21 and the guide rod 26 respectively. The movable block 23 can move stably on the guide rod 26, and the spring 27 provides power for the movable block 23 to reset on the guide rod 26, so that the movable block 23 can be stably stored inside the fixed cylinder 21.

[0027] Furthermore, the worm 210 meshes with the worm wheel 28, and the rotation of the worm 210 can drive the fixed cylinder 21 to rotate through the worm wheel 28.

[0028] Furthermore, the fixing frame 32 passes through the fixing cylinder 21, and the hydraulic cylinder 33 is installed vertically. The hydraulic cylinder 33 corresponds vertically to the slot 24. The hydraulic cylinder 33 is located inside the fixing cylinder 21. When the hydraulic cylinder 33 extends, it can be inserted into the slot 24 and push the movable block 23 on the lower side of the fixing cylinder 21 to move straight down, which facilitates the bending of the object with the lower mold 11.

[0029] Working principle: When in use, the motor 29 can be started, and the motor 29 drives the worm 210 to rotate. The worm 210 meshes with the worm wheel 28. The rotation of the worm 210 drives the fixed cylinder 21 to rotate through the worm wheel 28. The fixed cylinder 21 rotates inside the machine body 1 and drives the bending blade 25 inside to adjust its angle so that the corresponding bending blade 25 can be adjusted to the lower side of the fixed cylinder 21 according to the usage requirements.

[0030] The object is placed on the top surface of the lower mold 11, and the hydraulic cylinder 33 is activated. The hydraulic cylinder 33 extends and inserts its extended end downward into the slot 24 on the surface of a set of movable blocks 23 located directly below the fixed cylinder 21. This pushes the set of movable blocks 23 downward, causing the movable blocks 23 to move downward outside the guide rod 26 and compress the spring 27. The movable blocks 23 then move inside the through groove 22, which can drive the corresponding bending blade 25 downward, so that the bending blade 25 moves downward closer to the lower mold 11. At this time, the position of the fixed cylinder 21 is fixed, so the bending blades 25 located on the front and rear sides of the fixed cylinder 21 will not obstruct the bending of the object. This ensures that the object is fully bent with the cooperation of the bending blade 25 and the lower mold 11, improving the processing effect of the object and ensuring the user experience of the device.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
