Description

Technical Field

[0001] This utility model relates to the field of hydraulic bending machine technology, specifically a hydraulic bending machine with a stable support structure. Background Technology

[0002] Hydraulic bending machines are widely used in the metal processing field. During operation, they apply hydraulic pressure to bend metal materials at specific angles. In the process of using a hydraulic bending machine, the workpiece needs to be stably supported before bending. During bending, debris falls from the surface of the workpiece at the bending position, accumulating over time and making cleaning difficult. To overcome this defect, prior art 1 (Chinese patent application No. 201821140400.2, filed on 2018-07-18) describes a quick-access hydraulic bending machine. During operation, air blown from the vent carries away debris from the bending groove, preventing debris accumulation. This eliminates the need to stop the machine for cleaning, thus maintaining bending efficiency. The lower die is fixed to a trapezoidal fixing block via a connecting plate. The trapezoidal fixing block is fixed in place by installation; turning the handwheel separates the lower die from the mounting groove, allowing for easy removal, replacement, and maintenance of the lower die.

[0003] Due to the irregular shape of the debris, it may get stuck on the surface of the collection device. The device in the above application does not have a structure with multiple auxiliary feeding, resulting in incomplete debris collection, which will still cause unnecessary trouble for the staff. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic bending machine with a stable support structure to solve the problem mentioned in the background art, which is that the lack of a structure with multiple auxiliary feeding results in incomplete debris collection and still causes unnecessary trouble for workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic bending machine with a stable support structure, comprising an equipment box, a motor bolted to the outer wall of the equipment box, a fixed rod fixedly connected to the upper surface of the equipment box, and an auxiliary rod rotatably mounted on the upper surface of the equipment box; a clamping plate slidably mounted inside the equipment box, a fixed plate bolted to the upper surface of the equipment box, a hydraulic rod fixedly connected to the surface of the fixed plate, and a push plate fixedly connected to the output end of the hydraulic rod; a limit plate fixedly connected to the outer wall of the equipment box, and a receiving plate slidably mounted on the surface of the limit plate; an outer connecting plate fixedly connected to the outer wall of the equipment box, a movable plate sleeved on the surface of the outer connecting plate, and a striking rod fixedly connected to the upper surface of the movable plate.

[0006] Preferably, the output end of the motor is fixedly connected to a threaded rod, and the surface of the threaded rod is threadedly connected to the clamping plate, and a long pin is fixedly connected to the inner wall of the equipment box.

[0007] Preferably, the long pin extends through the interior of the clamping plate.

[0008] Preferably, a connecting plate is fixedly connected to the outer wall of the equipment box, and a connecting shaft is rotatably provided inside the connecting plate. A traction rope is fixedly connected to the surface of the push plate, and the other side of the traction rope is wound and fixedly connected to the surface of the connecting shaft.

[0009] Preferably, a cam is fixedly connected to the end of the connecting shaft, and a torsion spring is fixedly connected to the surface of the connecting shaft. The other side of the torsion spring is fixedly connected to the inner wall of the connecting plate. A first spring is fixedly connected to the surface of the receiving plate, and the other side of the first spring is fixedly connected to the inner wall of the limiting plate.

[0010] Preferably, the receiving plate is inclined, and a guide plate is fixedly connected to the upper surface of the receiving plate. The guide plate is also inclined and is symmetrically distributed on both sides of the receiving plate.

[0011] Preferably, a lower connecting rod is fixedly connected to the lower surface of the receiving plate, and a force-bearing block is fixedly connected to the upper surface of the movable plate. The force-bearing blocks are evenly distributed on the upper surface of the movable plate, and the ends of the force-bearing blocks are arc-shaped.

[0012] Preferably, a second spring is fixedly connected to the lower surface of the movable plate, and the other side of the second spring is fixedly connected to the inner wall of the outer plate, and the striking rods are evenly distributed on the upper surface of the movable plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the hydraulic bending machine with a stable support structure adopts a novel structural design, the specific details of which are as follows:

[0014] (1) In the process of using the hydraulic bending machine with a stable support structure, the workpiece is placed between the fixed rod and the clamping plate, and then the motor is started. When the motor is working, it drives the threaded rod to rotate. At this time, the clamping plate moves closer to the position of the fixed rod under the action of the threaded rod and the long pin. Finally, the clamping plate clamps the workpiece. At this time, the hydraulic rod is started so that the push plate can complete the bending function.

[0015] (2) When the hydraulic rod drives the push plate to work, the push plate drives the connecting shaft to rotate through the traction rope. At this time, the cam will intermittently push the receiving plate. Then, under the action of the thrust, the limit plate and the first spring, the receiving plate will make reciprocating linear motion in the horizontal direction. At this time, the receiving plate is in a state of slight vibration, which can quickly discharge the debris.

[0016] Furthermore, during the movement of the receiving plate, the lower connecting rod moves synchronously. At this time, the lower connecting rod intermittently pushes the force block, and the force block and the movable plate, under the action of the thrust, the outer connecting plate and the second spring, make reciprocating linear motion in the vertical direction. At this time, the movable plate intermittently strikes the lower surface of the receiving plate through the striking rod, thereby optimizing the material discharge effect of the receiving plate, improving work efficiency, and preventing the occurrence of debris adhesion residue.

[0017] (3) When the connecting shaft rotates inside the connecting plate, it will stretch the torsion spring. When the push plate moves back, the connecting shaft will lose the tension of the traction rope. At this time, the connecting shaft will rotate under the action of the torsion spring, and then the connecting shaft will rewind the traction rope, which is convenient for the next use of the connecting shaft and the traction rope.

[0026] 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.

[0027] This utility model provides the following technical solution: a hydraulic bending machine with a stable support structure.

[0028] Example 1: The bending function can be quickly achieved using the motor 2 and hydraulic rod 9, such as... Figures 1-2 As shown, the device includes a housing 1, a motor 2 bolted to the outer wall of the housing 1, a fixed rod 6 fixedly connected to the upper surface of the housing 1, and an auxiliary rod 7 rotatably mounted on the upper surface of the housing 1; a clamping plate 5 slidably mounted inside the housing 1, a fixed plate 8 bolted to the upper surface of the housing 1, a hydraulic rod 9 fixedly connected to the surface of the fixed plate 8, and a push plate 10 fixedly connected to the output end of the hydraulic rod 9; a threaded rod 3 fixedly connected to the output end of the motor 2, and a clamping plate 5 threadedly connected to the surface of the threaded rod 3; and a long pin 4 fixedly connected to the inner wall of the housing 1, the long pin 4 penetrating the interior of the clamping plate 5.

[0029] During use, the workpiece is placed between the fixed rod 6 and the clamping plate 5. Then, the motor 2 is started. When the motor 2 is working, it drives the threaded rod 3 to rotate. At this time, the clamping plate 5 moves closer to the fixed rod 6 under the action of the threaded rod 3 and the long pin 4. Finally, the clamping plate 5 clamps the workpiece. At this time, the hydraulic rod 9 is started so that the push plate 10 can complete the bending function.

[0030] Example 2: Unlike Example 1, the reciprocating receiving plate 14 allows for rapid collection and removal of debris, such as... Figures 3-6 As shown, a limiting plate 16 is fixedly connected to the outer wall of the equipment box 1, and a receiving plate 14 is slidably provided on the surface of the limiting plate 16; a connecting plate 11 is fixedly connected to the outer wall of the equipment box 1, and a connecting shaft 12 is rotatably provided inside the connecting plate 11; a traction rope 13 is fixedly connected to the surface of the push plate 10, and the other side of the traction rope 13 is wound and fixedly connected to the surface of the connecting shaft 12.

[0031] A cam 23 is fixedly connected to the end of the connecting shaft 12, and a torsion spring 22 is fixedly connected to the surface of the connecting shaft 12. The other side of the torsion spring 22 is fixedly connected to the inner wall of the connecting plate 11. A first spring 20 is fixedly connected to the surface of the receiving plate 14, and the other side of the first spring 20 is fixedly connected to the inner wall of the limiting plate 16. The receiving plate 14 is inclined, and a guide plate 15 is fixedly connected to the upper surface of the receiving plate 14. The guide plate 15 is also inclined and is symmetrically distributed on both sides of the receiving plate 14.

[0032] When the pusher plate 10 is working, it drives the connecting shaft 12 to rotate inside the connecting plate 11 via the traction rope 13. At this time, the connecting shaft 12 intermittently pushes the receiving plate 14 via the cam 23. When the receiving plate 14 is pushed, it slides on the surface of the limiting plate 16. At this time, the first spring 20 is squeezed. When the cam 23 continues to rotate until it stops pushing the receiving plate 14, the receiving plate 14 moves back under the action of the first spring 20. The above process is repeated, and the receiving plate 14 makes reciprocating linear motion in the horizontal direction. At this time, the receiving plate 14 can better discharge the debris and improve the working efficiency.

[0033] Example 3: Unlike Example 2, the movable plate 18 and the striking rod 19 are used to accelerate the discharge of debris from the receiving plate 14, preventing debris from sticking and remaining. Figure 7 As shown, an outer plate 17 is fixedly connected to the outer wall of the equipment box 1, and a movable plate 18 is sleeved and connected to the surface of the outer plate 17. A striking rod 19 is fixedly connected to the upper surface of the movable plate 18, a lower connecting rod 24 is fixedly connected to the lower surface of the receiving plate 14, a force-bearing block 25 is fixedly connected to the upper surface of the movable plate 18, and the force-bearing blocks 25 are evenly distributed on the upper surface of the movable plate 18. The ends of the force-bearing blocks 25 are arc-shaped. A second spring 21 is fixedly connected to the lower surface of the movable plate 18, and the other side of the second spring 21 is fixedly connected to the inner wall of the outer plate 17. The striking rod 19 is evenly distributed on the upper surface of the movable plate 18.

[0034] During the movement of the receiving plate 14, the lower receiving rod 24 will move synchronously. At this time, the lower receiving rod 24 will intermittently push the force block 25. When the force block 25 is pushed, the force block 25 and the movable plate 18 will move in the direction of squeezing the second spring 21. When the force block 25 is not pushed, the movable plate 18 rises under the action of the second spring 21 (the outer plate 17 makes the movable plate 18 move only in the vertical direction). Then, under the action of the pushing force, the outer plate 17 and the second spring 21, the movable plate 18 will make reciprocating linear motion in the vertical direction. At this time, the movable plate 18 will intermittently strike the lower surface of the receiving plate 14 through the striking rod 19, thereby optimizing the material discharge effect of the receiving plate 14, improving work efficiency, and preventing the occurrence of debris adhesion residue.

[0035] When the connecting shaft 12 rotates inside the connecting plate 11, it will stretch the torsion spring 22. When the push plate 10 moves back, the connecting shaft 12 will lose the tension of the traction rope 13. At this time, the connecting shaft 12 will rotate under the action of the torsion spring 22, and then the connecting shaft 12 will rewind the traction rope 13, making it convenient for the next use of the connecting shaft 12 and the traction rope 13.

[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
