Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically a mold steel feeding device with an anti-pinch mechanism. Background Technology

[0002] In the field of mold steel processing, the unloading process after mold steel cutting is crucial for ensuring production safety and processing quality. Traditional mold steel cutting devices often cause the cut mold steel to fall directly onto the unloading channel or conveyor mechanism, generating significant impact. On the one hand, this easily leads to dents and scratches on the mold steel, affecting its surface quality and subsequent processing accuracy; on the other hand, the significant impact can also damage the conveying equipment, shortening its service life and increasing maintenance costs.

[0003] In addition, the existing discharge device has shortcomings in controlling the discharge rhythm and cannot effectively control the amount of material discharged at one time. This may result in multiple mold steels being discharged and piling up at the same time, which not only affects the subsequent processing flow, but may also pose a safety hazard of operators being pinched due to manual intervention in sorting materials.

[0004] Therefore, those skilled in the art have provided a die steel unloading device with an anti-pinch mechanism to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a die steel feeding device with an anti-pinch mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A die steel unloading device with an anti-pinch mechanism includes a belt conveyor guide rail. The front end of the belt conveyor guide rail is provided with an unloading chute. The unloading chute is located below the cutting mechanism and is connected to the cutting part. A side opening is opened on the side of the unloading chute near the lower end. A base plate is fixedly installed at the bottom of the unloading chute at the position of the side opening by bolts. A rotating disk is rotatably connected to the upper end of the base plate. A connecting column is fixedly connected to the upper end of the rotating disk. Five levers arranged in a ring are fixedly connected to the outer wall of the connecting column.

[0008] As a further embodiment of this utility model: a connecting arm and a rotating block are rotatably connected to the upper end of the base plate, and a hook is fixedly connected to the front end of the connecting arm.

[0009] As a further improvement of this utility model: five slots corresponding to the lever are formed at equal angles on the outer wall of the rotating disk, and the hooks are adapted to the slots.

[0010] As a further embodiment of this utility model: a drive motor is fixedly installed at the lower end of the base plate, and the output shaft of the drive motor is fixedly connected to the rotating block through a reducer.

[0011] As a further embodiment of this utility model: a protrusion 1 is fixedly connected to one side of the connecting arm, and a protrusion 2 is fixedly connected to the outer wall of the rotating block.

[0012] As a further embodiment of this utility model: a guide sleeve is fixedly installed on the upper end of the base plate on one side of the connecting arm, a return spring is provided inside the guide sleeve, and a guide rod is provided at the front end of the return spring and slidably connected to the guide sleeve, with the front end of the guide rod abutting against the connecting arm.

[0013] As a further improvement of this utility model: the front end of the guide rod is provided with a hemispherical abutment, and the connecting arm is provided with an arc-shaped groove at the position corresponding to the hemispherical abutment.

[0014] As a further embodiment of this utility model: connecting plates are fixedly installed on both sides of the unloading chute near the lower end by bolts, and the unloading chute is fixedly connected to the belt conveyor rail through the connecting plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model provides a rotating disc with a lever at the bottom of the unloading chute. When the mold steel slides down, it is first blocked by the lever, which effectively buffers the impact force of the falling mold steel and prevents the mold steel from directly impacting the belt conveyor rail or other conveying mechanisms. This not only protects the surface of the mold steel from bumps and scratches and ensures the quality of the mold steel, but also reduces the risk of equipment damage due to impact, extends the service life of the equipment, and reduces maintenance costs.

[0017] 2. By utilizing the combination of hooks and slots, as well as the linkage of components such as drive motors, rotating blocks, and connecting arms, only one mold steel is released at a time, precisely controlling the quantity and rhythm of material output. No manual intervention is required in the material output process, avoiding the risk of operators being pinched while handling materials, and significantly improving production safety.

[0018] 3. The abutment structure between the guide rod and the connecting arm, in conjunction with the return spring, enables the connecting arm to return to its stable position, ensuring that the hook accurately engages with the slot and maintaining the stability and reliability of the device's operation; the annular layout design of the rotating disk, connecting column, and lever can evenly withstand the impact force of the falling mold steel, further enhancing the stability of the device.

[0024] 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.

[0025] Example 1

[0026] Reference Figures 1-4 This embodiment provides a mold steel unloading device with an anti-pinch mechanism, including a belt conveyor rail 1. Continuous conveying is achieved through the belt conveyor rail 1, avoiding manual handling, reducing labor intensity and minimizing the risk of pinching injuries. The front end of the belt conveyor rail 1 is provided with an unloading chute 2, which is located below the cutting mechanism and connects to the cutting part. The unloading chute 2 connects the cutting mechanism and the belt conveyor rail 1, guiding the cut mold steel blank to slide down a preset path and using gravity to achieve initial unloading. A side opening 3 is provided on the side of the unloading chute 2 near its lower end. A base plate 7 is fixedly installed at the bottom of the unloading chute 2 at the position of the side opening 3 by bolts. A rotating disk 13 is rotatably connected to the upper end of the base plate 7. A connecting column 4 is fixedly connected to the upper end of the rotating disk 13. Five levers 5 arranged in a ring are fixedly connected to the outer wall of the connecting column 4.

[0027] Example 2

[0028] Reference Figures 1-4This embodiment is based on the previous embodiment, but differs in that a connecting arm 8 and a rotating block 9 are rotatably connected to the upper end of the base plate 7. A hook 12 is fixedly connected to the front end of the connecting arm 8. Five slots 14 corresponding to the levers 5 are equally spaced on the outer wall of the rotating disk 13. The hooks 12 are adapted to the slots 14. The rotating disk 13 serves as a support base for the levers 5, and intermittent rotation is achieved through the cooperation of the slots 14 and the hooks 12. The connecting column 4 is fixed at the center of the rotating disk 13 and is used to install five levers 5 arranged in a ring. The number of slots 14 is the same as that of the levers 5 to ensure accurate rotation angle each time. The connecting arm 8 serves as a lever structure, and the engagement and disengagement of the hooks 12 and the slots 14 are controlled by rotation. When the hooks 12 and the slots 14 are engaged, the rotating disk 13 is locked, and rotation is allowed when they are disengaged.

[0029] Furthermore, a drive motor 15 is fixedly installed at the lower end of the base plate 7, and the output shaft of the drive motor 15 is fixedly connected to the rotating block 9 through a reducer; a protrusion 10 is fixedly connected to one side of the connecting arm 8, and a protrusion 21 is fixedly connected to the outer wall of the rotating block 9; the rotating block 9 is driven by the drive motor 15 through the reducer, which causes the protrusion 21 to periodically press the protrusion 10, and the protrusion 211 pushes the connecting arm 8 to rotate, thereby realizing the unlocking action of the hook 12.

[0030] Furthermore, a guide sleeve 16 is fixedly installed on one side of the connecting arm 8 at the upper end of the base plate 7. A return spring is provided inside the guide sleeve 16. The front end of the return spring is provided with a guide rod 17 that is slidably connected to the guide sleeve 16. The front end of the guide rod 17 abuts against the connecting arm 8. A hemispherical abutment is provided at the front end of the guide rod 17. An arc-shaped groove is provided at the position of the connecting arm 8 corresponding to the hemispherical abutment. When the second protrusion 11 presses against the first protrusion 10, the guide rod 17 compresses the return spring and stores elastic potential energy. After the second protrusion 11 leaves, the return spring pushes the guide rod 17 to reset, so that the hook 12 relocks the next slot 14. The hemispherical abutment at the front end of the guide rod 17 cooperates with the arc-shaped groove of the connecting arm 8 to reduce frictional resistance.

[0031] Furthermore, the unloading chute 2 is fixedly installed with connecting plates 6 on both sides near the lower end by bolts, and the unloading chute 2 is fixedly connected to the belt conveyor rail 1 through the connecting plates 6.

[0032] Working principle: In the initial state, the slot 14 on the rotating disk 13 is engaged with the hook 12 at the front end of the connecting arm 8, and the rotating disk 13 is fixed and cannot rotate. The five levers 5 are arranged in a ring around the connecting column 4, with one lever 5 located directly below the side opening 3 of the unloading chute 2, forming a blocking structure to receive the falling mold steel. After the cylindrical mold steel is cut into a disc shape, it slides down through the unloading chute 2. Since the rotating disk 13 is locked, the falling mold steel will hit the lever 5 in the blocking position. The lever 5 absorbs the impact force of the mold steel and blocks the high-speed falling mold steel, preventing it from falling directly to the belt conveyor rail 1 and causing a large impact, thereby protecting the mold steel and the belt conveyor rail 1. After the mold steel is blocked by the lever 5, the drive motor 15 at the lower end of the base plate 7 starts to work. The output shaft of the drive motor 15 drives the rotating block 9 to rotate slowly through the reducer. The reducer's function is to lower the rotational speed and increase the torque, ensuring smooth rotation of the rotating block 9. As the rotating block 9 rotates, the second protrusion 11 on its outer wall gradually approaches the first protrusion 10 on the connecting arm 8. When the second protrusion 11 slides past the first protrusion 10, it pushes the connecting arm 8 to rotate around its rotation point with the base plate 7. The connecting arm 8 drives the front end hook 12 to exit the slot 14, and at the same time, the connecting arm 8 pushes the guide rod 17 to slide into the guide sleeve 16, squeezing the return spring. At this time, the rotating disk 13 loses the restriction of the hook 12. After the rotating disk 13 is unlocked, it begins to rotate under the gravity of the mold steel, driving the lever 5 to rotate, causing the blocked mold steel to slide down onto the belt conveyor guide rail 1. The belt conveyor guide rail 1 starts, transporting the mold steel to the subsequent station, completing the unloading process of a single mold steel. After the mold steel slides onto the belt conveyor guide rail 1, the rotating disk 13 continues to rotate at a certain angle. Under the elastic force of the return spring, the guide rod 17 pushes the connecting arm 8 forward to reset, so that the hook 12 hooks the next slot 14 on the rotating disk 13 again, and the rotating disk 13 is locked again, waiting to receive the next falling mold steel. This cycle repeats to achieve orderly and buffered discharge of mold steel.
