Description

Technical Field

[0001] The present invention relates to the technical field of bending equipment, and in particular to bending equipment for production of construction site elevators and a use method thereof. Background Art

[0002] With the acceleration of urbanization and the increase in high-rise buildings, construction site elevators, as an indispensable and important means of transportation in construction, play a vital role in ensuring construction efficiency and safety. The main structural components of construction site elevators include columns, beams, door panels, etc. These components need to be precisely bent during the manufacturing process to ensure that they meet the design requirements. When bending the elevator door panel, most processing methods are to bend one side of the elevator door panel first, then flip the elevator door panel through a robotic arm, and put the other side of the elevator door panel into a bending machine for bending, which is time-consuming and labor-intensive, and has low production efficiency.

[0003] After searching the Chinese patent publication number (CN118122837A), a bending device for elevator door panel processing was found. The device drives the panel to move closer to the lower plate through the upper plate, so that the bending plates on both sides of the lower plate can bend the long edge of the panel synchronously and simultaneously in two sections during the downward movement of the lower plate. Compared with the conventional multiple bending of the long sides of the panel, the processing efficiency of the elevator door panel is greatly improved, and through the movement of the arc block and the first arc groove, the flipping point position of the bending plate is not hindered by the hinge to affect the bending effect of the panel, so that the panel can be bent smoothly. In addition, the opening formed by the bending plate and the arc block is movable, so that the upper plate can drive the panel to smoothly and quickly separate from the lower plate, thereby realizing rapid unloading of the bent panel.

[0004] Although this type of equipment solves the above-mentioned problems, there are still some problems in actual use. When the elevator door panel is bent, the four sides of the panel need to be bent. However, when this type of equipment bends the panel, the two longer sides are first bent, and then the panel is removed and bent by another device for bending the two short sides. This adds some processing steps, which is time-consuming and labor-intensive. At the same time, after the two longer sides of the door panel are bent into shape, they are inwardly wrapped, and the sides hold the two opposite sides of the support plate. Therefore, when disassembling, the door panel needs to be pulled out from the front or back of the support plate. Due to the large area of ​​the panel, it is inconvenient to unload.

[0036] The embodiment of the present invention provides a bending device for the production of construction site elevators and a method for use. The bending device for the production of construction site elevators and the method for use can realize the bending of the four sides of a plate through a bending component. First, the two longer sides are bent, and then the two shorter sides are bent. The bending of the four sides of the plate is completed at one time without the need to transfer to the next process for processing, thereby reducing the work steps and greatly improving efficiency.

[0037] The bending device for production of construction site elevator and the method of use are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0038] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings and specific implementation methods. Example 1

[0039] See also Figure 1 and Figure 2 The present embodiment provides a bending device for production of construction site elevators, comprising: a processing table 1, a loading table 11 and a unloading table 12 are fixedly connected on opposite sides of the processing table 1, a mounting groove 13 is provided on the processing table 1, a bending table 14 is fixedly installed at the bottom of the mounting groove 13, a contour plate 15 is provided on the bending table 14, an electromagnet 16 is provided inside the contour plate 15, and a hydraulic station 17 is provided inside the processing table 1; a bending component, the bending component is provided on the mounting groove 13, and is used to bend the elevator door panel; a unloading component is provided on the contour plate 15; grooves 4 are respectively provided on the loading table 11 and the unloading table 12, and feeding components are respectively provided inside the two grooves 4.

[0040] When in use, the plate is placed on the loading platform 11, and the contour plate 15 moves to the top of the loading platform 11, and the magnetism of the electromagnet 16 is used to adsorb the plate, and then the plate is transferred to the bending platform 14, and the plate is clamped by the contour plate 15 and the bending platform 14, and then the bending component is started by the hydraulic station 17, and the four sides of the plate are bent by the bending component. After the processing is completed, the formed elevator door panel is moved to the unloading platform 12, and at the same time, the electromagnet 16 is powered off and loses its magnetism, and the adsorption of the elevator door panel is released. The unloading component is started by the hydraulic station 17, and the unloading component runs to separate the elevator door panel from the contour plate 15, and then the contour plate 15 moves to the loading platform 11 again to grab the material for processing. The feeding component will be started when the contour plate 15 moves. When it moves to the right, the feeding component on the unloading platform 12 is started to transport the elevator door panel to the unloading area. When it moves to the left, the feeding component on the loading platform 11 is started to transport the plate to the designated area for the contour plate 15 to grab and process. Example 2

[0041] See also Figure 2 and Figure 6On the basis of Example 1, the feeding assembly includes a support roller 41, a transmission roller 42, a sprocket 43, a chain 44 and a conveyor belt 45. The two support rollers 41 are arranged between the inner walls on the opposite sides of the two grooves 4, the transmission roller 42 is arranged between the inner walls on the opposite sides of the two grooves 4 near the middle position, the sprocket 43 is arranged outside the support roller 41 and the transmission roller 42 near the two ends, the chain 44 is located between the sprockets 43 on the same side, and the conveyor belt 45 is arranged between the outsides of the two chains 44. Active grooves 46 are respectively opened at the top of the loading platform 11 and the unloading platform 12 near the bottom end of the column 5, and the rotating shafts of the opposite ends of the two transmission rollers 42 are respectively provided with transmission rods 47, and the opposite ends of the two transmission rods 47 extend to the inside of the two active grooves 46 respectively, and the opposite ends of the two transmission rods 47 are respectively provided with transmission gears 48, and the two transmission gears 48 are connected to the two ratchet wheels 57 through a transmission chain.

[0042] When the hydraulic push rod 53 moves to the right, the ratchet wheel 57 on the left rotates, and then drives the transmission gear 48 on the left to rotate through the transmission chain, and the transmission gear 48 drives the transmission roller 42 to rotate, and the transmission roller 42 drives the sprocket 43 to mesh with the chain 44, and then drives the chain 44 to drive the conveyor belt 45 to move. The two support rollers 41 limit the movement trajectory of the chain 44, so that the conveyor belt 45 on the unloading platform 12 transports the formed elevator door panel to the unloading area for unloading. Since the ratchet wheel 57 on the right is idling, the ratchet wheel 57 on the right will not be transmitted, so that the plate It stops on the loading platform 11. When the hydraulic push rod 53 moves to the left, the ratchet 57 on the right rotates. According to the above principle, the conveyor belt 45 on the loading platform 11 conveys the plate to the designated position to wait for grabbing. The transmission ratio of the ratchet 57 and the transmission gear 48 is equal to the moving distance of the slider 52, so that when the slider 52 moves from the fixed position on the right to the fixed position on the left, the conveyor belt 45 on the loading platform 11 just conveys the plate to the designated position. Conversely, the conveyor belt 45 on the unloading platform 12 just moves the formed elevator door panel to the unloading area, so that the entire processing process is smooth and the processing efficiency is improved. Example 3

[0043] See also Figure 3 and Figure 8 On the basis of Example 1, the bending assembly includes a base 2, a bending plate 21, a bending cavity 22, a bending rod 23 and a piston 24. The base 2 is arranged around the bending table 14, the bending plate 21 is arranged on the base 2, two bending cavities 22 are opened on the base 2, the bending rod 23 is arranged inside the bending cavity 22, and the piston 24 is arranged inside the bending cavity 22. The four bending plates 21 are all arranged in an L-shaped structure, and the four bending plates 21 are respectively arranged opposite to the four sides of the contour plate 15, one end of the bending rod 23 is connected to the bending plate 21, and the other end of the bending rod 23 is connected to the piston 24, and the hydraulic pipes of the hydraulic station 17 are respectively connected to the two ends of the bending cavity 22 and are conductive with the inside.

[0044] Grab the plate from the loading platform 11 and place it on the bending platform 14. When bending the plate, send hydraulic oil into the cavity from the top of the bending cavity 22 through the hydraulic pipe of the hydraulic station 17. First, send the hydraulic oil into the bending cavity 22 of the left and right bases 2. After the hydraulic oil enters, it pushes the internal piston 24 to move to the lower end. The piston 24 pushes the bending rod 23 to extend out of the bending cavity 22. The bending plate 21 is pushed to deflect through the bending rod 23. The bending plates 21 on the left and right sides fold the two longer sides of the plate toward the center. The two long sides are folded After completion, the hydraulic station 17 is used to control the hydraulic oil to be sent into the bottom end of the bending cavity 22, and the hydraulic oil in the other cavity returns to the hydraulic station 17, thereby causing the piston 24 to move toward the top of the bending cavity 22, and the bending plates 21 on the left and right sides are driven to open to both sides through the bending rods 23, and then the bending rods 23 on the front and rear sides are controlled by the hydraulic station 17 to bend the two shorter sides of the plate according to the same principle as above. After the bending is completed, the bending rods 23 on the front and rear sides return to the initial state, thereby bending the plate into shape at one time. Example 4

[0045] See also Figure 4 and Figure 5 as well as Fig. 9 On the basis of Example 1, the unloading assembly includes a first side plate 31, a second side plate 32, a first piston rod 34 and a second piston rod 36. The peripheral sides of the contour plate 15 are respectively provided with receiving grooves 3. The first side plate 31 is arranged inside the receiving groove 3. The second side plate 32 is arranged inside the receiving groove 3 on the front and rear opposite sides. Two main hydraulic chambers 33 are respectively provided at positions adjacent to the two first side plates 31 inside the contour plate 15. The first piston rod 34 is arranged inside the main hydraulic chamber 33. The first piston rod 34 is respectively connected to the first side plate 31 on the same side. Auxiliary hydraulic chambers 35 are respectively provided at positions adjacent to the two second side plates 32 inside the contour plate 15. The second piston rod 36 is arranged at the auxiliary hydraulic chambers 33. Inside the cavity 35, one end of the second piston rod 36 is respectively connected to the second side plate 32 on the same side, the hydraulic pipes of the hydraulic station 17 are respectively connected to the two main hydraulic chambers 33 and the two auxiliary hydraulic chambers 35. Guide grooves 37 are respectively opened at the positions between the two main hydraulic chambers 33 inside the contour plate 15, and guide rods 38 are respectively provided inside the two guide grooves 37. The two guide rods 38 are respectively connected to the opposite sides of the two first side plates 31. Limiting grooves 39 are respectively opened at the positions on both sides of the auxiliary hydraulic chamber 35 inside the contour plate 15. Limiting rods 310 are respectively provided inside the two limiting grooves 39, and the two limiting rods 310 are respectively connected to the opposite sides of the two second side plates 32.

[0046] The contour plate 15 moves the formed elevator door panel to the unloading platform 12, and then the hydraulic oil enters the cavity from the outermost ends of the main hydraulic chamber 33 and the auxiliary hydraulic chamber 35 through the hydraulic station 17. After the hydraulic oil enters, it pushes the first piston rod 34 to retract into the main hydraulic chamber 33, and the second piston rod 36 to retract into the auxiliary hydraulic chamber 35. When the first piston rod 34 and the second piston rod 36 move, they will drive the two first side plates 31 and the two second side plates 32 to move into the storage groove 3. At the same time, the two first side plates 31 and the two second side plates 32 will drive the two The guide rod 38 and the limiting rod 310 move to retract the guide rod 38 into the guide groove 37, and the limiting rod 310 retracts into the limiting groove 39, thereby starting the guiding function for the first side plate 31 and the second side plate 32, and the two ends of the two first side plates 31 and the two second side plates 32 are respectively designed with a flat angle, and the two first side plates 31 and the two second side plates 32 are adjacent to each other. After being retracted into the storage groove 3, the two first side plates 31 and the two second side plates 32 are assembled into a rectangular parallelepiped, so that the storage can be opened without affecting the storage. The plate is supported by the two first side plates 31 and the two second side plates 32 when the plate is bent, so that the four edges of the bent plate are wrapped on the two first side plates 31 and the two second side plates 32. When the two first side plates 31 and the two second side plates 32 are received in the storage slot 3, the elevator door panel loses support and falls off from the contour plate 15 under the action of gravity, and falls on the unloading platform 12 to complete the unloading. Then, the hydraulic station 17 controls the hydraulic oil to flow from the main hydraulic chamber 33 and the auxiliary hydraulic chamber 35. The end closest to the center enters the cavity, pushing the first piston rod 34 and the second piston rod 36 out, and at the same time, the hydraulic oil in the outermost cavity flows back to the hydraulic station 17, and the two first side plates 31 and the two second side plates 32 are pushed out of the receiving groove 3 by the first piston rod 34 and the second piston rod 36, so that they return to the initial position, and the guide rod 38 is pushed out from the guide groove 37, and the limit rod 310 is pushed out from the limit groove 39. The first piston rod 34 and the second piston rod 36 are sealed with the main hydraulic chamber 33 and the auxiliary hydraulic chamber 35. Example 5

[0047] See also Figure 2 and Figure 7On the basis of Example 2, the tops of the loading platform 11 and the unloading platform 12 are fixedly connected to the columns 5 respectively, and two symmetrically arranged guide rails 51 are fixedly connected between the two columns 5. Slide blocks 52 are arranged outside the two guide rails 51, and a hydraulic push rod 53 is arranged on the front side of the slide block 52. A connecting plate 54 is arranged at the bottom end of the hydraulic push rod 53, and the bottom of the connecting plate 54 is connected to the top of the contour plate 15.

A driving motor 58 is arranged on one side of one column 5, and one end of the driving shaft of the driving motor 58 is connected to one end of the threaded rod 55 on one side.

[0048] The threaded rod 55 is driven to rotate by starting the driving motor 58. When the threaded rod 55 rotates, it is screwed with the threaded block 56, thereby driving the threaded block 56 to drive the slider 52 to move outside the two guide rails 51. When the slider 52 moves, it will drive the hydraulic push rod 53 to move. The hydraulic push rod 53 is connected to the contour plate 15 through the connecting plate 54, thereby controlling the contour plate 15 to move. The driving motor 58 is a forward and reverse motor. By controlling the reverse rotation of the driving motor 58, the contour plate 15 is controlled to move left or right. By controlling the hydraulic push rod 53 to eject or retract, the contour plate 15 can be driven to move upward or downward. During processing, the contour plate 15 is controlled to move right, and the plate is grabbed from the loading table 11 and placed on the bending table 14. When moving to the right, the threaded rod 55 will drive the ratchet 57 on the left to rotate and the ratchet 57 on the right to rotate idly. When moving to the left, the ratchet 57 on the right rotates and the ratchet 57 on the left to rotate idly.
