[0003] In the process of material processing, in order to meet actual needs, it is often necessary to use bending devices to bend the materials to form bent materials.

[0004] When bending strip profiles and column materials, existing bending devices can bend the materials to the required degree of bending. However, when bending multiple materials at the same time, some bending sections are prone to bending deviation, which affects the bending effect. Summary of the Invention

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] In this invention, the metal material bending device includes a frame;

[0010] A bending mold connected to the top of the frame is provided above the frame, and the bending mold has multiple mold slots.

[0011] The bending die has a lower positioning plate on the outer side of the bending end. The lower positioning plate is connected to the drive component three installed on the frame and is driven by the drive component three to reciprocate in the direction of approaching or moving away from the bending die. The direction from the bending die to the lower positioning plate is the feeding direction. The top of the lower positioning plate is connected to the upper positioning plate through the cylinder two and is used to clamp and transfer the bent part.

[0012] The frame is also equipped with a cylinder, the actuating end of which is connected to one end of the robotic arm to drive the robotic arm to reciprocate in the feeding direction; the other end of the robotic arm is connected to the abutment plate through a drive component, which drives the abutment plate to rotate; one side of the abutment plate is provided with an embedding groove corresponding to the mold groove.

[0013] The surface of the abutment plate with the embedded groove can be driven by cylinder 1, robotic arm 1 and drive component 1 to gradually move from below the bending end of the bending mold to above the bending mold. During this process, the abutment plate will fit against the top surface of the bending mold. When it fits, the mold groove and the embedded groove form the bending groove of the workpiece to be bent, and the workpiece to be bent in the mold groove and bending groove is bent at this time.

[0014] The bending die and the lower positioning plate are integrated, and a cutting machine is also provided on the outside. The cutting machine is connected to the frame through a second driving component. The second driving component drives the cutting machine to perform linear reciprocating motion, and the cutting machine cuts the bent part during the motion.

[0015] Furthermore, the abutment plate is provided with an adapter plate that corresponds one-to-one with the embedding groove. Multiple adapter plates are integrally formed with the abutment plate, and each adapter plate is adapted to the corresponding embedding groove.

[0016] Furthermore, two symmetrically arranged support structures are installed on the frame, and the two symmetrically arranged support structures are used to place the receiving frame;

[0017] The frame is also equipped with an inclined feeding plate; two supporting structures are located at the lower inclined end of the feeding plate.

[0018] Furthermore, a frame is provided on the frame, and the frame and the surface of the frame form a material collection frame, and a flow pipe is integrally formed on the frame;

[0019] The frame is provided with a discharge trough adapted to the flow pipe. The flow pipe is embedded in the discharge trough, and the gaps are sealed by a sealing element. The discharge trough is semi-cylindrical, and the bottom of the discharge trough is lower than the inner bottom of the frame.

[0020] Furthermore, the flow pipe is located inside the frame with a rounded corner on one side, and the outer arc of the rounded corner contacts the bottom of the discharge trough.

[0021] Furthermore, a stirring structure connected to the robotic arm is provided. The stirring structure includes multiple connecting plates, and each connecting plate has an elastic brush at the end away from the robotic arm.

[0022] Furthermore, multiple disturbance cavities are formed on the elastic brush.

[0023] Furthermore, the bending die is detachably connected to the limiting structure via an mounting component, and the limiting structure is connected to the frame;

[0024] The mounting component includes two symmetrically arranged mounting plates, each with a plurality of corresponding threaded holes, and the bending die has a plurality of insertion holes.

[0025] A method for bending a metallic material, the method comprising:

[0026] The part to be bent slides along the mold groove in the bending mold through the feeding structure in the feeding direction, and the single sliding length of the part to be bent is the bending length.

[0027] The abutment plate moves to the bending end of the bending die through the cylinder. At this time, the end of the abutment plate near the bending die is aligned with the bending end of the bending die, and the part of the part to be bent is embedded in the embedding groove on the abutment plate.

[0028] Under the action of the robotic arm, drive component 1 and cylinder 1, the abutment plate bends the part to be bent, so that the part to be bent fits the mold groove on the bending mold and bends. After bending, the abutment plate is separated from the part to be bent.

[0029] The feeding structure feeds the workpiece to be bent. When the workpiece reaches the required cutting length, the drive unit 2 is activated, causing the cutting machine to cut the bent workpiece.

[0030] Furthermore, the feeding structure feeds the workpiece to be bent, and after feeding it to the required cutting length, it also includes:

[0031] When the third drive unit and the second cylinder move, the bent part is clamped between the lower positioning plate and the upper positioning plate. At this time, the bent part is positioned in the positioning groove opened on the upper positioning plate. Then the second drive unit moves to cut the bent part.

[0032] The driving component three and cylinder two actuate to move the cut and bent workpiece away from the bending mold and release it from the clamping of the lower and upper positioning plates.

[0033] (III) Beneficial Effects

[0034] This invention provides a metal material bending device and method. Compared with the prior art, it has the following advantages:

[0035] Beneficial effects:

[0036] By setting a limiting structure, which is in the form of a bending mold and a mold groove, and combined with an abutment plate, an embedding groove corresponding to the mold groove is set on the abutment plate. Through the bending groove formed by the mold groove and the embedding groove, the workpiece to be bent according to the first to fourth states is bent. The mold groove is adapted to the bending angle, which can realize multi-segment bending of the material. When performing multi-segment bending, the mold groove is used to limit the bending part and the section connecting the workpiece to be bent to the bending part during the bending process, which improves the bending stability during simultaneous multi-segment bending. This solves the problem in the prior art that the bending segment of the material is prone to bending deviation when the material is simultaneously bent in multiple segments, resulting in poor multi-segment bending effect.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] This application provides a metal material bending device and method, which solves the problem in the prior art where bending segments of the material are prone to deviation when bending multiple segments simultaneously, thereby improving the bending effect during the bending process.

[0056] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0057] Example:

[0058] like Figures 1-5 As shown, a metal material bending device is used to bend a workpiece 6, including a frame 1, a housing 2, a limiting structure 3, and a cutting structure 5.

[0059] The chassis 2 is mounted on the frame 1 and is fixedly connected to the frame 1 by multiple bolts. The chassis 2 is equipped with a robotic arm 20 and a pneumatic assembly 21. A drive component is provided between the pneumatic assembly 21 and the robotic arm 20. The drive component is used to control the rotation of the pneumatic assembly 21 at the end of the robotic arm 20. An abutment plate 211 is provided inside the pneumatic assembly 21. The abutment plate 211 has an embedded groove adapted to the part 6 to be bent.

[0060] The limiting structure 3 is installed on the frame 1 and is fixedly connected to the frame 1 by multiple bolts. A bending die 30 is installed on the limiting structure 3. The bending die 30 has multiple die slots 301 that correspond one-to-one with the embedding slot. Each die slot 301 is adapted to the bending angle of the workpiece 6 to be bent.

[0061] The machine box 2 is equipped with a cylinder 201, which is used to control the robotic arm 20 to control the contact plate 211 to move closer to or away from the bending mold 30 along the feeding direction.

[0062] When the abutment plate 211 is in contact with the bending die 30, the die groove 301 and the embedding groove form the bending groove of the workpiece 6 to be bent.

[0063] After the bending part 6 is bent, the portion of the bending part 6 near the bending die 30 is embedded inside the die groove 301, specifically as follows: Figure 3 As shown;

[0064] The cutting structure 5 is connected to the frame 1 via a support base 51. A cutting machine 50 is mounted on the support base 51. A second driving component is installed inside the support base 51. A second sliding plate 511 is fixedly connected to the moving end of the second driving component. The cutting machine 50 is slidably connected to the support base 51 via the second sliding plate 511 and moves closer to or further away from the limiting structure 3 via the second driving component.

[0065] In the first state, the workpiece 6 to be bent slides along the mold groove 301 below the bending mold 30 via the feeding structure. The single sliding length of the workpiece 6 to be bent is the bending length, as detailed below. Figure 4 As shown in the first state diagram;

[0066] In the second state, the abutment plate 211 approaches the bending die 30 via the cylinder 201. The end of the abutment plate 211 approaching the bending die 30 is aligned with the bending end of the bending die 30. The end of the part to be bent 6 away from the bending die 30 is embedded in the corresponding embedding groove on the abutment plate 211, specifically as follows: Figure 4 In this process, the entire process is the transformation of the first state diagram into the second state diagram;

[0067] In the third state, under the action of the robotic arm 20, the drive unit 1, and the cylinder 201, the abutment plate 211 bends the part of the workpiece 6 to be bent. The part to be bent conforms to the mold groove 301 on the bending mold 30 and is bent. After bending, the abutment plate 211 detaches from the part to be bent, specifically as follows: Figure 4 In the process, the second state diagram transforms into the third state diagram;

[0068] In the fourth state, the feeding structure continues to feed the workpiece 6 to be bent until it reaches the required cutting length, specifically as follows: Figure 4 As shown in the fourth state diagram, the cutting machine 50 then approaches the bending portion of the workpiece 6 to be bent via the second drive component and starts cutting the bending portion of the workpiece 6.

[0069] By setting a limiting structure 3, which is configured as a bending mold 30 and a mold groove 301, and combined with an abutment plate 211, an embedding groove corresponding to the mold groove 301 is set on the abutment plate 211. Through the bending groove formed by the mold groove 301 and the embedding groove, the workpiece 6 to be bent of the corresponding shape is bent according to the first to the fourth state. The mold groove 301 is adapted to the bending angle, which can realize multi-segment bending of the material. When performing multi-segment bending, the mold groove 301 is used to limit the bending part and the segment connecting the workpiece 6 to the bending part during the bending process, thereby improving the bending stability during the simultaneous multi-segment bending process. This solves the problem in the prior art that the bending segment of the material is prone to bending deviation when the material is simultaneously bent in multiple segments, resulting in poor multi-segment bending effect.

[0070] like Figures 2-4 As shown, the abutment plate 211 is provided with an adapter plate 212 that corresponds to the embedding groove one by one. Multiple adapter plates 212 are integrally formed with the abutment plate 211, and each adapter plate 212 is adapted to the corresponding embedding groove.

[0071] In the second state, the joints between the multiple adapter plates 212 and the abutment plate 211 are located in the first bending section, which is used to support the part 6 to be bent.

[0072] By setting multiple adapter plates 212 that correspond one-to-one with the embedding slots, the adapter plates 212 support the first bending segment during bending, thereby improving the stability during the bending process and further reducing the problem that the bending segment is prone to displacement during bending, resulting in poor bending effect.

[0073] like Figure 1 , Figures 3-4As shown, the bending device also includes a positioning structure 4, which is installed on the frame 1 via a base. The positioning structure 4 includes a lower positioning plate 40 and an upper positioning plate 41. The upper positioning plate 41 is located above the lower positioning plate 40 and moves closer to or further away from the lower positioning plate 40 via a cylinder 411.

[0074] The lower positioning plate 40 is slidably connected to the base via multiple sliding plates 401;

[0075] The base is equipped with a driving component three. The moving end of the driving component three drives multiple sliding plates 401 to move the lower positioning plate 40 closer to or away from the bending mold 30.

[0076] The upper positioning plate 41 has multiple positioning grooves that are adapted to the bending part 6 at one end near the lower positioning plate 40.

[0077] The surface of the lower positioning plate 40 near the upper positioning plate 41 is horizontal with the bottom surface of the part to be bent 6.

[0078] In the fifth state, before the cutting structure 5 in the fourth state is cut, the driving component three controls the lower positioning plate 40 to approach the bent portion of the workpiece 6 to be bent. The upper surface of the lower positioning plate 40 contacts the workpiece 6 to be bent, and the bent portion is located between the lower positioning plate 40 and the upper positioning plate 41. The cylinder two 411 drives the upper positioning plate 41 to approach the lower positioning plate 40. The positioning groove on the upper positioning plate 41 contacts the corresponding bent portion and clamps and positions the bent portion, as detailed below. Figure 4 The fourth and fifth state diagrams are shown in the diagram.

[0079] By setting up the positioning structure 4, the bent part of the part to be bent 6 is positioned, thereby improving the stability of the subsequent cutting process of the cutting machine 50 and reducing the error generated when the cutting machine 50 cuts multiple parts to be bent.

[0080] like Figure 1 As shown, two symmetrically arranged support structures 11 are installed on the frame 1, and the two symmetrically arranged support structures 11 are used to place the receiving frame.

[0081] An inclined feeding plate 42 is installed on the positioning structure 4;

[0082] The two supporting structures 11 are located at the inclined lower end of the blanking plate 42;

[0083] In the initial state, the lower positioning plate 40 is located above the material feeding plate 42;

[0084] After the cutting structure 5 cuts, the positioning structure 4 clamps the cut bent part and returns to the initial state under the action of the driving component 3. The cylinder 2 411 controls the upper positioning plate 41 to move away from the lower positioning plate 40. The bent part 6 cut between the upper positioning plate 41 and the lower positioning plate 40 slides down along the unloading plate 42 into the receiving frame placed between the two supporting structures 11.

[0085] By setting the feeding plate 42, the collection of cut materials is convenient, and the whole operation process is simple.

[0086] like Figure 3 As shown, the bending die 30 is detachably connected to the limiting structure 3 via the mounting part 31;

[0087] The mounting component 31 includes two symmetrically arranged mounting plates 311, each with a plurality of corresponding threaded holes 313, and the bending die 30 has a plurality of insertion holes 312.

[0088] By setting the mounting part 31, it is easy to disassemble and replace the bending die 30. At the same time, multiple insertion holes 312 are opened on the bending die 30, and the bending die 30 is inserted into the insertion holes 312 to achieve dual stability of the installation of the bending die 30.

[0089] like Figures 6-8 As shown, a frame 10 is provided on the frame 1, and the frame 10 and the surface of the frame 1 form a material collection frame. A flow pipe 102 is integrally formed on the frame 10.

[0090] The frame 1 is provided with a discharge trough 101 adapted to the flow pipe 102. The flow pipe 102 is embedded in the discharge trough 101, and the gap is sealed by a sealing element. The discharge trough 101 is semi-cylindrical, and the bottom of the discharge trough 101 is lower than the inner bottom of the frame 10.

[0091] During cutting, the cutting fluid and the water used for cooling the metal enter the collection frame, flow through the discharge trough 101, and flow out through the flow pipe 102.

[0092] By setting up a discharge trough 101, which is opened on the frame 1, the bottom of the discharge trough 101 is lower than the inner bottom of the frame 10, which facilitates the outflow of cutting fluid with metal chips. At the same time, the flow pipe 102 facilitates the installation of the drain pipe, realizing the discharge of cutting fluid and clean water used for metal cooling.

[0093] It should be noted that in actual use, water can be drained in a measured amount. When the water accumulates to a certain depth inside the frame 10, it can be discharged all at once, which can achieve a better discharge effect and prevent the problem that shallow water is not conducive to the discharge of debris.

[0094] like Figure 8As shown, the flow pipe 102 is located inside the frame 10 with a rounded corner on one side, and the outer arc of the rounded corner 103 contacts the lower end of the discharge trough 101, which further facilitates the discharge of chips from the cutting fluid and the clean water used for metal cooling.

[0095] like Figure 1 , Figure 6 as well as Figures 8-9 As shown, an agitation structure 22 is installed at the connection between the robotic arm 20 and the housing 2. The agitation structure 22 includes multiple connecting plates 221, and each connecting plate 221 is provided with an elastic brush 222 at the end away from the robotic arm 20.

[0096] Multiple disturbance cavities 223 are formed on the elastic brush 222;

[0097] When the robotic arm 20 controls the contact plate 211 to move closer to or further away from the bending die 30 along the feeding direction, the agitation structure 22 moves synchronously within the frame 10 and disturbs the water flow within the frame 10, reducing the deposition of debris and facilitating the discharge of water within the frame 10. Multiple agitation chambers 223 can enhance the disturbance effect of the agitation structure 22 on the water flow, further improving the discharge effect of water within the frame 10.

[0098] Specifically, each of the connecting plates 221 is integrally formed with the corresponding elastic brush 222. In use, the end of the elastic brush 222 away from the connecting plate 221 comes into contact with the water flow inside the frame 10.

[0099] It should be noted that the entire device is equipped with a water tank structure for cooling during metal cutting; this is existing technology and will not be elaborated upon.

[0100] During operation, step one: the external feeding structure feeds the workpiece 6 to be bent, and the entire device is in the first state. At this time, the workpiece 6 to be bent slides along the mold groove 301 below the bending mold 30 through the feeding structure. The single sliding length of the workpiece 6 to be bent is the bending length, as detailed below. Figure 4 As shown in the first state diagram;

[0101] Step Two: The entire device moves from the first state to the second state. At this time, the abutment plate 211 approaches the bending die 30 via cylinder 201. The end of the abutment plate 211 approaching the bending die 30 is aligned with the bending end of the bending die 30. The end of the bent part 6 away from the bending die 30 is embedded in the corresponding embedding groove on the abutment plate 211, specifically as follows: Figure 4 In this process, the entire process is the transformation of the first state diagram into the second state diagram;

[0102] Step 3: The entire device moves from the second state to the third state. At this time, under the action of the robotic arm 20, the drive component 1, and the cylinder 201, the abutment plate 211 bends the part to be bent 6. The part to be bent conforms to the mold groove 301 on the bending mold 30 and is bent. After bending, the abutment plate 211 detaches from the part to be bent, specifically as follows: Figure 4 In the process, the second state diagram transforms into the third state diagram;

[0103] At the same time, when the robotic arm 20 controls the contact plate 211 to move closer to or further away from the bending die 30 along the feeding direction, the agitation structure 22 moves synchronously within the frame 10 and disturbs the water flow within the frame 10.

[0104] Step 4: The entire device moves from the third state to the fourth state. At this time, the feeding structure continues to feed the workpiece 6 to be bent. When the feed reaches the required cutting length, the entire device moves from the fourth state to the fifth state. Driver 3 controls the lower positioning plate 40 to approach the bent portion of the workpiece 6 to be bent. The upper surface of the lower positioning plate 40 contacts the workpiece 6 to be bent. The bent portion is located between the lower positioning plate 40 and the upper positioning plate 41. Cylinder 2 411 drives the upper positioning plate 41 to approach the lower positioning plate 40. The positioning groove on the upper positioning plate 41 contacts the corresponding bent portion and clamps and positions the bent portion. Specifically, as shown... Figure 4 The fourth and fifth state diagrams are shown in the diagram.

[0105] Step 5: Finally, the cutting machine 50 approaches the bent part of the part to be bent 6 through the second drive component and starts cutting the bent part of the part to be bent 6. After the cutting structure 5 cuts, the positioning structure 4 clamps the cut bent part and returns to the initial state under the action of the third drive component. The cylinder 2 411 controls the upper positioning plate 41 to move away from the lower positioning plate 40. The part to be bent 6 cut between the upper positioning plate 41 and the lower positioning plate 40 slides down along the unloading plate 42 into the receiving box placed between the two supporting structures 11.

[0106] It should be noted that the die groove 301 on the bending die 30, the embedding groove on the abutment plate 211, and the positioning groove on the upper positioning plate 41 are adapted to the shape of the part 6 to be bent, and can process columnar materials or strip profiles, as shown in the following example. Figure 4 The columnar embodiment and Figure 5 Strip structure diagram.

[0107] In summary, compared with existing technologies, it has the following beneficial effects:

[0108] 1. By setting a limiting structure 3, which is in the form of a bending mold 30 and a mold groove 301, and combined with an abutment plate 211, an embedding groove corresponding to the mold groove 301 is set on the abutment plate 211. Through the bending groove formed by the mold groove 301 and the embedding groove, the bending part and the section connecting the workpiece 6 to the bending part during the bending process are limited by the mold groove 301, which improves the bending stability during the simultaneous multi-segment bending process. This solves the problem in the prior art that when the material is bent in multiple segments simultaneously, the bending segment of the material is prone to bending deviation, resulting in poor multi-segment bending effect.

[0109] 2. By setting up the positioning structure 4, the bent part of the part to be bent 6 is positioned, which improves the stability of the subsequent cutting process of the cutting machine 50 and reduces the error generated when the cutting machine 50 cuts multiple parts to be bent.

[0110] 3. By setting up the discharge trough 101, the discharge trough 101 is opened on the frame 1, so that the bottom of the discharge trough 101 is lower than the inner bottom of the frame 10, which facilitates the flow of cutting fluid with metal chips. At the same time, the flow pipe 102 can facilitate the installation of the drain pipe, so as to realize the discharge of cutting fluid and clean water used for metal cooling.
