Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a double-station curling and pre-bending engraving machine. Background Art

[0002] For barrel-shaped, columnar and pot-shaped metal products, there are more or less rolled round plates (arc-shaped plate-like structural parts) on them, such as the reinforcing plates at the hanging ears and the reinforcing plates at the hole openings, which are all arc-shaped structures. In addition, in order to facilitate installation and distinguish the processed parts, words are usually engraved on them when processing the above-mentioned arc-shaped plate-like structural parts for marking.

[0003] At present, the method used for rolling circular plates is usually to use a bending machine to bend the entire plate to obtain an annular circle, and then cut the annular circle into multiple rolled circular plates according to the required length. For example, the pre-bent flat plate rolling method disclosed in patent CN103817178A pre-bends the two ends of the flat plate, and then puts the flat plate with pre-bent ends into a three-roller rolling machine for rolling, so as to obtain a product with the required curvature. Although the above method can meet the needs of rolling circular plates, since the rolling machine requires at least three rollers above and below to bend the plate body, the length of the workpiece to be processed needs to be greater than the distance between the axial centers of two rollers at the same height among the three rollers, so that the length of the workpiece to be processed must be longer to be processed. Even after processing, it needs to be cut into multiple rolled circular plates of shorter lengths. The working process is cumbersome and inefficient. In addition, during actual processing, due to the random relative positions of the roller and the workpiece to be processed, engraving cannot be achieved during the rolling process. It is necessary to use a professional industrial engraving machine to perform the engraving operation after the rolling is completed and cut, realizing the step-by-step rolling and engraving. Not only is the cost high, but the product needs to be transferred multiple times, further reducing the processing efficiency and is not conducive to the processing and manufacturing of rolled plates.

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 2 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0026] Figure 1 This is a structural diagram of an embodiment of a double-station pre-bending cutting plotter of the present invention. Figure 1 As shown, the double-station curling and pre-bending engraving machine provided in this embodiment includes: a platform frame 1, a vertical frame 2, a telescopic drive 3 and a curling mold 4.

[0027] Specifically, the platform frame 1 is a frame structure, with two rolling stations 11 located on top. These stations 11 serve as a platform for subsequent bending and curling, facilitating the placement and operation of the rolling die 4. Furthermore, the two rolling stations 11 are spaced apart on the platform frame 1, preventing interference between them during processing and providing enhanced safety. Preferably, the top surface of each rolling station 11 is a platform plate, providing a horizontal, planar support structure, ensuring the stable placement of the rolling die 4 and achieving a more rational structural design.

[0028] Specifically, the stand 2 is arranged on the platform frame 1 in the vertical direction, and the lower end of the stand 2 is fixed to the platform frame 1, so that the stand 2 is stably installed on the platform frame 1. In addition, one rolling station 11 corresponds to one stand 2, so that each rolling station 11 has a stand 2 as an installation structure for the subsequent telescopic drive 3, thereby ensuring that each rolling station 11 can subsequently have a corresponding telescopic drive 3 to cooperate with the work. Preferably, the lower and upper ends of the stand 2 are both provided with support arms protruding toward one side. The support arm at the lower end of the stand 2 is arranged on the outside of the corresponding rolling station 11 to achieve auxiliary support and protection. The support arm at the upper end of the stand 2 extends to the top of the rolling station 11, serving as the installation carrier of the corresponding telescopic drive 3, ensuring that the subsequently installed telescopic drive 3 can face the rolling station 11 in the vertical direction.

[0029] Specifically, each stand 2 is equipped with a telescopic drive 3, and each telescopic drive 3 is arranged vertically downward, so that the driving shaft of the telescopic drive 3 is raised and lowered in the vertical direction, providing conditions for subsequently driving the upper arc-shaped pressing die 41 in the rolling die 4 to approach or move away from the lower arc-shaped pressing die 42 in the vertical direction.

[0030] Specifically, a rolling die 4 is provided between each telescopic drive 3 and the corresponding rolling station 11. At this time, the rolling die 4 includes an upper arc-shaped pressing die 41 and a lower arc-shaped pressing die 42. During processing, the strip plate to be processed is placed between the upper arc-shaped pressing die 41 and the lower arc-shaped pressing die 42. The strip plate to be processed is bent by the mutual extrusion between the upper arc-shaped pressing die 41 and the lower arc-shaped pressing die 42 to achieve rolling processing. In addition, it is preferred that the upper arc-shaped die 41 is a concave die, and the lower arc-shaped die 42 is set as a convex die corresponding to the upper arc-shaped die 41. During installation, the upper arc-shaped die 41 is installed on the driving shaft of the corresponding telescopic driver 3, so that the upper arc-shaped die 41 can move up and down in the vertical direction. At the same time, the lower arc-shaped die 42 is movably placed on the rolling station 11, so that the upper arc-shaped die 41 can approach or move away from the lower arc-shaped die 42, which provides conditions for the subsequent bending of the strip plate to be processed between the upper arc-shaped die 41 and the lower arc-shaped die 42. In addition, the lower arc-shaped die 42 movably placed on the rolling station 11 can automatically adjust its position when pressing down, ensuring that the lower arc-shaped die 42 can fully cooperate with the upper arc-shaped die 41, realizing adaptive bending operation, higher structural flexibility, and simplifying the loading process. In addition, a letter-shaped protrusion 43 is provided on the inner wall of the concave side of the upper arc-shaped pressing die 41 or on the outer wall of the convex side of the lower arc-shaped pressing die 42, so that when the upper arc-shaped pressing die 41 and the lower arc-shaped pressing die 42 are closed to bend the strip plate, the letter-shaped protrusion 43 can simultaneously engrave words on the strip plate, thereby realizing simultaneous bending and engraving, thereby improving processing efficiency.

[0031] More specifically, the platform frame 1 is provided with a drive circuit 5, which comprises a fuel tank, a pump body, a tee connector, and a control valve. During assembly, the pump body's liquid inlet is connected to the fuel tank, while one port of the tee connector is connected to the pump body's oil outlet. The other two ports of the tee connector are connected to the liquid inlets of the two telescopic actuators 3, respectively. This allows the pump body to supply hydraulic oil from the fuel tank to the two telescopic actuators 3, powering their movement. Simultaneously, the liquid outlets of the two telescopic actuators 3 are connected to the fuel tank, enabling oil return from the telescopic actuators 3 and thus recycling the hydraulic oil. Furthermore, control valves are provided on the connecting pipes between the two ports of the tee connector and the corresponding telescopic actuators 3. That is, a control valve is provided between each telescopic actuator and the tee connector. The control valves regulate the opening and closing of the corresponding connecting pipes, thereby controlling the movement of different telescopic actuators 3 and meeting the subsequent independent control requirements of the different telescopic actuators 3.

[0032] More specifically, the two control valves used to respectively control the two telescopic actuators 3 are in opposite opening and closing states, that is, when one control valve is opened, the other control valve is closed, and conversely, when one control valve is closed, the other control valve is opened, so that only one of the two telescopic actuators 3 is actuated during each operation, that is, the two telescopic actuators 3 form an interlocking structure, which avoids the operational risks of the two telescopic actuators 3 actuating at the same time. In addition, the pump body only needs to provide power to one telescopic actuator 3 at a time, meeting the use requirement of a set of drive circuits 5 to provide power for two telescopic actuators 3. The utilization rate of structural parts is higher, and the manufacturing and use costs are reduced.

[0033] More specifically, the two control valves used to control the opening and closing of the connecting pipes of the two telescopic actuators 3 are both solenoid valves. In this case, the control circuits of both control valves are connected to control pedals, which means that the operator can control the movement of the corresponding telescopic actuator 3 through the control pedals, making operation more convenient. In addition, the two control pedals are arranged separately, which effectively avoids safety issues caused by interference when the operator uses the control pedals, and the structural design is more reasonable.

[0034] More specifically, the drive circuit 5 also includes two one-way valves. At this time, the two one-way valves are arranged on the connecting pipeline between the two control valves and the liquid inlets of the two corresponding telescopic drives 3, which effectively avoids the problem of reverse flow during the hydraulic oil transportation process and ensures the stability and reliability of the hydraulic oil supply.

[0035] Figure 2 This is a cross-sectional view of a rolling die according to a preferred embodiment of the present invention. Figure 1 and Figure 2As shown, each telescopic actuator 3's drive shaft is mounted with an upper mounting block 31. This expands the mounting area at the end of the drive shaft, facilitating the subsequent connection of the upper arc-shaped die 41. The center of the upper mounting block 31 is connected to the drive shaft of the telescopic actuator 3, ensuring balanced force after installation. Furthermore, several fixing holes 311 are provided on the outer sides of the upper mounting block 31. The corresponding upper arc-shaped die 41 is connected to the fixing holes 311 on the upper mounting block 31, achieving a more convenient connection between the upper arc-shaped die 41 and the upper mounting block 31.

[0036] More specifically, a plurality of connection holes 411 are provided on the inner wall of the concave side of the upper arc-shaped pressing die 41, extending vertically upward and penetrating the upper arc-shaped pressing die 41. Each connection hole 411 corresponds to a fixing hole 311, facilitating the subsequent connection of the connection holes 411 and the fixing holes 311 to achieve connection between the upper arc-shaped pressing die 41 and the upper mounting block 31. During installation, a connection bolt is provided in each connection hole 411, which penetrates into the corresponding fixing hole 311 and is threadedly connected. That is, the connection bolt passes through the connection hole 411 and is threadedly connected to the corresponding fixing hole 311, thereby achieving rapid disassembly and assembly between the upper arc-shaped pressing die 41 and the upper mounting block 31, facilitating replacement of the rolling die 4.

[0037] More specifically, the fixing holes 311 on the upper mounting block 31 are blind holes. Each fixing hole 311 is arranged vertically downward, thus maintaining the integrity of the upper surface of the upper mounting block 31 and preventing dust accumulation and other issues that affect cleaning. Furthermore, the connecting holes 411 are countersunk, and the countersunk ends of the connecting holes 411 are located on the inner wall of one side of the concave cavity of the upper arc-shaped die 41, so that the connecting holes 411 are located on the bottom surface of the upper arc-shaped die 41. Furthermore, the ends of the connecting bolts are embedded in the countersunk ends of the connecting holes 411, achieving concealed installation of the connecting bolts. This prevents the problem of failing to fully press the strip plate when bending it, ensuring accuracy in bending.

[0038] More specifically, two parallel and spaced ridges 421 are provided on the bottom surface of the lower arc-shaped pressing die 42. When the lower arc-shaped pressing die 42 is placed on the rolling station 11, it can contact the rolling station 11 through the ridges 421, reducing the contact area between the bottom surface of the lower arc-shaped pressing die 42 and the rolling station 11, so that in the subsequent bending process, the position of the lower arc-shaped pressing die 42 can be adaptively adjusted, and the structural design is more reasonable.

[0039] More specifically, a protective baffle 6 is provided around the periphery of each rolling station 11, and a protective structure is formed on the outside of the rolling station 11 through the protective baffle 6. At this time, the corresponding lower arc-shaped pressing die 42 is placed in the area surrounded by the protective baffle 6, which can prevent the lower arc-shaped pressing die 42 from slipping off the rolling station 11, and provide higher safety protection.

[0040] The double-station pre-bending plotter provided in this embodiment includes a platform frame 1, a stand 2, a telescopic drive 3 and a rolling die 4; two rolling stations 11 are arranged on the platform frame 1, and each rolling station 11 is equipped with a telescopic drive 3 arranged vertically downward through the stand 2. At the same time, a rolling die 4 is provided between the telescopic drive 3 and the corresponding rolling station 11, and the upper arc-shaped pressing die 41 of the rolling die 4 is installed on the driving shaft of the telescopic drive 3, and the lower arc-shaped pressing die 42 is movably placed on the corresponding rolling station 11, and the upper arc A letter-shaped protrusion 43 is provided on the upper arc-shaped pressing die 41 or the lower arc-shaped pressing die 42 and on the opposite side of the two. The strip plate to be processed between the two is bent by closing the upper arc-shaped pressing die 41 and the lower arc-shaped pressing die 42 and engraved with the letter-shaped protrusion 43, thereby realizing the simultaneous processing of rolling and engraving. The steps are simple and the processing efficiency is higher. At the same time, there is no need to consider the length of the strip plate to be processed during the bending process. The length of the strip plate can be selected according to the required length, avoiding the problem of needing to cut after rolling in the later stage, which is beneficial to the processing and manufacturing of the rolled plate.

[0041] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
