Description

Technical Field

[0001] The utility model relates to the technical field of identification plate production, in particular to a bending device for identification plate production. Background Art

[0002] A bending device for signboard production uses a hydraulic system to drive a slider up and down, using a mold to precisely bend the sheet metal. The slider's speed and pressure are controlled by a CNC system to achieve bending requirements at various angles and shapes. This equipment is widely used in the metalworking industry, efficiently and accurately completing complex bending tasks. Adjusting the hydraulic system pressure and slider position allows for the processing of metal components at various angles and shapes.

[0003] After searching, the Chinese patent document announcement number: CN217191789U discloses a bending and forming device for the production of signboards, including a base, a bending groove is provided on the base, a vertical groove is provided on the base, a horizontal groove connected to the vertical groove is provided on the base, a stop block is slidably connected to the vertical groove, and a limit member is provided on the base for limiting the movement of the stop block, a rotating block is hinged on the base, and the rotating block is connected to a connecting block by bolts, a notch is provided on the connecting block, a card block with an extending slot is slidably connected to the connecting block, and the side wall of the card block is fixedly connected to a side block slidably connected to the notch, a spring is fixedly connected to the notch, and the end of the spring is fixedly connected to the bottom of the side block.

[0004] The beneficial effects of the above patent specification mentions that "by adjusting the stop block according to the size of the sign to move in the corresponding transverse groove, when the stop block moves to the specified position, the round rod is passed through the round hole through the stop block and extended into the transverse groove, so that the stop block is restricted, and then the position of the connecting block is adjusted. A plurality of screw holes are provided at the connection between the connecting block and the rotating block. The bolts are screwed into the screw holes at different positions to adjust the distance between the rotating block and the connecting block. Under the action of the spring, the card block can be extended into the card slot provided on the stop block, so that the position of the connecting block is fixed. Therefore, sign boards of different sizes can be bent between the blocks. The operation is relatively convenient and quick, eliminating tedious steps." Although the above patent can be adjusted in real time according to the size of the sign board, the technical solution lacks an anti-slip material device when in use, causing it to slide and break during processing. For this reason, a bending device for sign board production is proposed to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the existing technology and provide a bending device for the production of identification plates, which solves the problem of damage caused by sliding of identification plates during processing by adding an anti-slip material device.

[0016] As a further description of the above technical solution:

The electric push rod pulls the transmission rod downward to rotate the rotating plate 1 and the rotating plate 2, and changes from a horizontal bias to a longitudinal bias, so that the fixed plate is pressed down to fix the identification plate on the surface of the material placement plate, thereby preventing the material from slipping when the identification plate is bent, thereby greatly ensuring the quality of the product.

[0024] 2. The utility model can buffer the pressure generated by the pressing knife through the buffer component. When the pressing knife presses down and contacts the identification plate, the identification plate is squeezed and bent toward the inside of the bending groove. When it contacts the buffer cap, the buffer spring at the bottom of the buffer cap is deformed to relieve part of the pressure. The piston rod is squeezed downward by the pressure, and the internal hydraulic oil flows through the liquid outlet to relieve the pressure. At the same time, the presence of the hydraulic oil can prevent the buffer spring from rebounding so quickly to affect the squeezing of the pressing knife, greatly reducing the risk of early damage to the identification plate due to excessive pressure from the pressing knife.

[0025] In summary, the utility model has the advantages of preventing the identification plate from sliding during processing, which may lead to processing failure, and preventing the material from being damaged due to excessive pressure from the pressing knife. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Reference Figure 1 , Figure 2 , Figure 5 , wherein the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that: the buffer assembly includes a buffer assembly shell 20 for fixing the internal assembly, the buffer assembly shell 20 is fixedly connected to the interior of the body 1, the inner wall of the buffer assembly shell 20 is fixedly connected to a liquid storage tank 18 for storing hydraulic oil and other damping media, the inner wall of the liquid storage tank 18 is slidably connected to a hydraulic piston 17, the hydraulic piston 17 plays a buffering role in squeezing the internal liquid, the interior of the hydraulic piston 17 is provided with a liquid outlet 21 to facilitate the flow of the damping medium, and at the same time, holes of different sizes can also control the rebound speed of the spring, so that the buffer spring 16 placed inside the buffer assembly rebounds quickly.

[0039] The top of the hydraulic piston 17 is fixedly connected to a piston rod 19 for transmitting pressure. The top of the piston rod 19 is fixedly connected to a buffer cap 15 for bearing the pressure of the pressing knife 22. The bottom of the buffer cap 15 is fixedly connected to a buffer spring 16 for buffering the pressure of the pressing knife 22. The top of the body 1 is fixedly connected to a hydraulic cylinder 25 for providing power to the pressing knife 22 to press it down. The driving end of the hydraulic cylinder 25 is fixedly connected to a pressure rod 24, which drives the pressing knife 22 to be pressed down or raised by the up and down movement of the pressure rod 24. The bottom of the pressure rod 24 is fixedly connected to a fixed plate 23 for fixing the pressing knife 22. The bottom of the fixed plate 23 is fixedly connected to the pressing knife 22. A bending groove 27 is provided inside the body 1 to facilitate deformation of the plate squeezed by the pressing knife 22.

[0040] Working steps

[0041] Step 1. When the sign needs to be extruded and bent, the sign to be processed is placed on the surface of the loading plate 2, and then the electric push rod 3 is started. The electric push rod 3 pulls the transmission rod 4, and the downward movement of the transmission rod 4 drives the rotating rod 6 to move downward. The downward movement of the rotating rod 6 causes the rotating plate 1 7 and the rotating plate 2 9 to rotate, from a horizontal bias to a longitudinal bias, so that the fixed plate 13 is pressed down to fix the sign on the surface of the loading plate 2. At the same time, the hydraulic cylinder 25 is started to drive the fixed plate 23 and the pressing knife 22 to press down. At this time, the cylinder 28 is started to drive the loading plate 2 to move upward. While the pressing knife 22 is pressed downward, the loading plate 2 moves upward to bend the plate, and the existence of the bending groove 27 makes the sign bent into shape.

[0042] Step 2. During the process of the pressing knife 22 pressing down, it is inevitable that part of the plate will be damaged or bent excessively due to excessive force due to excessive pressure. The pressure generated by the pressing knife 22 can be buffered by the buffer component. When the pressing knife 22 presses down and contacts the identification plate, the identification plate is squeezed and bent into the bending groove 27. When it contacts the buffer cap 15, the buffer spring 16 at the bottom of the buffer cap 15 sends a deformation to relieve part of the pressure. The piston rod 19 is squeezed downward by the pressure, and the hydraulic oil flows through the liquid outlet 21 to relieve the pressure. At the same time, the presence of the hydraulic oil can prevent the buffer spring 16 from rebounding so quickly to affect the squeezing of the pressing knife 22.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
