Description

Technical Field

[0001] This utility model relates to the field of bending equipment for advertising, specifically to a bending machine. Background Technology

[0002] In the field of advertising signage production, the production of various three-dimensional letters, such as metal letters and neon letters, has always been an important business area. With the continuous development of the advertising industry, increasingly higher demands are being placed on the shape, precision, and production efficiency of the letters.

[0003] Traditional letter bending primarily relies on manual operation or simple bending tools. While manual bending can achieve a certain degree of letter bending and shaping, it has many drawbacks. First, manual operation is highly dependent on the experience and skill level of the workers, resulting in inconsistent shapes and sizes, leading to varying product quality and failing to meet the demands of large-scale standardized production. Second, manual bending is extremely inefficient, consuming significant manpower and time, severely restricting production progress and the company's economic benefits. For example, even a skilled worker may need several hours to complete a relatively complex three-dimensional metal letter, and this inefficient production method becomes even more inadequate when dealing with bulk orders.

[0004] With the development of mechanized processing technology, some simple letter bending machines have begun to appear on the market. These machines have improved the efficiency and accuracy of letter bending to some extent, but they still have significant limitations. Early letter bending machines could mostly only perform bending operations in one direction. For fonts requiring double bends or complex shapes, they often could not achieve one-time forming. This meant that when producing such fonts, multiple machines or multiple clamping and adjustments were needed to complete the process, which not only increased equipment investment costs, but also easily introduced errors during the frequent clamping and adjustment process, reducing the overall accuracy and quality of the product. For example, for artistic fonts with double bends or special curves, existing ordinary letter bending machines have difficulty accurately replicating the design shape, often requiring a lot of subsequent manual trimming work.

[0005] Furthermore, existing letter bending machines have shortcomings in terms of material adaptability. Advertising production uses a wide variety of materials, including metal sheets of varying thicknesses, hardness, and material properties (such as stainless steel and aluminum), as well as some plastic sheets. Traditional letter bending machines often require changing different molds or adjusting numerous parameters when processing different materials, making operation cumbersome and time-consuming. This not only reduces production efficiency but also increases equipment maintenance costs and the workload of operators. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a bending machine with high production efficiency and simple operation.

[0007] The purpose of this utility model is achieved through the following technical measures: a bending machine, including a frame, characterized in that: a material guiding mechanism, a robotic arm feeding mechanism, an encoder detection mechanism, a grooving clamping mechanism, a grooving mechanism, and a double bending mechanism for a letter bending machine are sequentially installed on the frame. The material guiding mechanism is used to guide the material into the robotic arm feeding mechanism. The robotic arm feeding mechanism is provided in two sets, and the two sets of robotic arm feeding mechanisms alternately clamp the material and convey it forward. After being detected by the encoder detection mechanism, the material enters the grooving clamping mechanism for clamping. The grooving mechanism performs grooving work. The grooved material enters the double bending mechanism for letter bending processing.

[0008] As a preferred embodiment: the double bending mechanism of the bending machine includes a base, a drive shaft, a drive gear, a reducer, a motor, a cylinder, a striking bending rod, a lower driven gear, a bending device, a striking and squeezing bending assembly, and an upper driven gear. The drive shaft is fixedly connected to the drive gear, the reducer is drivenly connected to the motor, and the reducer is drivenly connected to the drive shaft. The base, drive shaft, drive gear, reducer, motor, cylinder, striking bending rod, lower driven gear, bending device, and upper driven gear constitute a striking bending mechanism for completing the striking bending action. When the striking bending mechanism is working, the striking and squeezing bending assembly needs to be removed.

[0009] As a preferred embodiment: the drive shaft passes through the base, and an upper drive gear is fixedly connected to one end of the drive shaft at the top of the base. The base, drive shaft, reducer, motor, bender, slap-squeeze bending assembly, and upper driven gear constitute a slap-squeeze bending mechanism.

[0010] As a preferred embodiment: the extrusion bending assembly includes an extrusion bending positioning mechanism, an extrusion bending rotation mechanism, an extrusion bending lower positioning shaft, and an extrusion bending upper fixing plate. The extrusion bending positioning mechanism and the extrusion bending rotation mechanism are rotatably connected, forming an extrusion space between them for extruding profiles. The extrusion bending rotation mechanism is installed inside the extrusion bending lower positioning shaft, and the extrusion bending positioning mechanism is fixedly connected to the bending machine by bolts.

[0011] As a preferred embodiment: both the extrusion bending positioning mechanism and the extrusion bending rotation mechanism are rotatably mounted with several rotating copper columns, the rotating copper columns are axially rotatable, and the extrusion bending positioning mechanism has arc surfaces on both sides near the mounting base.

[0012] As a preferred embodiment, the bending device is fixedly connected to the base by bolts.

[0013] Due to the adoption of the above technical solution, the advantages of this utility model compared with the prior art are:

[0014] This utility model discloses a bending machine, including a frame. The frame is sequentially equipped with a material guiding mechanism, a robotic arm feeding mechanism, an encoder detection mechanism, a grooving clamping mechanism, a grooving mechanism, and a double bending mechanism for letter bending. The material guiding mechanism guides the material into the robotic arm feeding mechanism. Two sets of robotic arm feeding mechanisms are provided, and the two sets alternately clamp and convey the material forward, resulting in very high efficiency. The double bending mechanism can perform both slapping and extrusion bending on sheet metal or profiles. Different bending mechanisms can be selectively chosen to perform letter bending work according to different materials and user needs.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0022] Example: As attached Figure 1 Only attached Figure 6 As shown, the bending machine includes a frame, on which are sequentially mounted a material guiding mechanism 1, a robotic arm feeding mechanism 2, an encoder detection mechanism 3, a grooving clamping mechanism 4, a grooving mechanism 5, and a double bending mechanism 6. The material guiding mechanism 1 is used to guide the material into the robotic arm feeding mechanism 2. The robotic arm feeding mechanism 2 is provided with two sets, and the two sets of robotic arm feeding mechanisms 2 alternately clamp the material and convey it forward. After being detected by the encoder detection mechanism 3, the material enters the grooving clamping mechanism 4 for clamping. The grooving mechanism 5 performs grooving work. The grooved material enters the double bending mechanism 6 of the bending machine for bending and lettering processing.

[0023] It should be noted that the material guiding mechanism 1, the robotic arm feeding mechanism 2, the encoder detection mechanism 3, the grooving clamping mechanism 4, and the grooving mechanism 5 in this application are all existing technologies and equipment. Their working principles and composition structures should be known to those skilled in the art, so they will not be described in detail here.

[0024] The double bending mechanism 6 of the bending machine includes a base 61, a drive shaft 62, a drive gear 63, a reducer 64, a motor 65, a cylinder 66, a striking bending rod 67, a lower driven gear 68, a bending device 69, a striking and squeezing bending assembly 610, and an upper driven gear 611. The drive shaft 62 is fixedly connected to the drive gear 63, and the reducer 64 is drivenly connected to the motor 65 and the drive shaft 62. The base 61, drive shaft 62, drive gear 63, reducer 64, motor 65, cylinder 66, striking and bending rod 67, lower driven gear 68, bending device 69, and upper driven gear 611 form a striking bending mechanism to complete the striking bending action. When the striking bending mechanism is working, the striking and squeezing bending assembly 610 needs to be removed.

[0025] The drive shaft 62 passes through the base 61, and an upper drive gear 621 is fixedly connected to one end of the drive shaft 62 at the top of the base 61. The base 61, drive shaft 62, reducer 64, motor 65, bender 69, slap-squeeze bending assembly 610 and upper driven gear 611 constitute a slap-squeeze bending mechanism.

[0026] The base 61 is provided with a processing space, and the patting bending mechanism and the patting extrusion bending mechanism are located in the processing space. When the patting extrusion bending assembly 610 is installed in the processing space, the patting bending rod 67 is retracted and located at the bottom of the base 61.

[0027] The extrusion bending assembly 610 includes an extrusion bending positioning mechanism 71, an extrusion bending rotation mechanism 72, an extrusion bending lower positioning shaft 73, and an extrusion bending upper fixing plate 74. The extrusion bending positioning mechanism 71 and the extrusion bending rotation mechanism 72 are rotatably connected, forming an extrusion space between them for extruding profiles. The extrusion bending rotation mechanism 72 is installed inside the extrusion bending lower positioning shaft 73, and the extrusion bending positioning mechanism 71 is fixedly connected to the bending device 69 by bolts.

[0028] Both the patting and bending positioning mechanism 71 and the patting and bending rotating mechanism 72 are rotatably mounted with several rotating copper columns. The rotating copper columns are axially rotatable. The patting and bending positioning mechanism 71 has arc surfaces on both sides near the mounting base 61.

[0029] The bending device 69 is fixedly connected to the base 61 by bolts.

[0030] It should be noted that the patting bending mechanism and the patting extrusion bending mechanism in this application operate independently and cannot operate simultaneously.

[0031] Traditional patting and bending mechanisms can easily leave marks on sheet metal, affecting its appearance. This new mechanism can perform both patting and bending of sheet metal or profiles, as well as extrusion bending. Both mechanisms have several copper pillars that rotate axially. These rotating pillars position the material and perform the patting and bending process. The presence of these rotating copper pillars avoids the drawback of leaving patting marks.
