[0060] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0061] Example:

[0062] like Figure 1-Figure 5 As shown, a metal material bending device with a cutting function is used to bend a part 6 to be bent, and includes a frame 1, a chassis 2, a limiting structure 3 and a cutting structure 5;

[0063] The chassis 2 is mounted on the frame 1 and fixedly connected to the frame 1 by a plurality of bolts. A mechanical arm 20 and a pneumatic assembly 21 are mounted on the chassis 2. A driving member 1 is arranged between the pneumatic assembly 21 and the mechanical arm 20. The driving member 1 is used to control the pneumatic assembly 21 to rotate at the end of the mechanical arm 20. An abutment plate 211 is arranged inside the pneumatic assembly 21. An embedding groove adapted to the part to be bent 6 is provided on the abutment plate 211.

[0064] The limiting structure 3 is installed on the frame 1 and fixedly connected to the frame 1 by a plurality of bolts. A bending die 30 is installed on the limiting structure 3. The bending die 30 is provided with a plurality of die grooves 301 corresponding to the embedding grooves one by one. Each of the die grooves 301 is adapted to the bending angle of the part 6 to be bent.

[0065] The chassis 2 is provided with a cylinder 1 201 for controlling the robot arm 20 to control the abutment plate 211 to approach or move away from the bending die 30 along the feeding direction;

[0066] When the abutment plate 211 is fitted with the bending die 30, the die groove 301 and the embedding groove form a bending groove of the part to be bent 6;

[0067] After the bending piece 6 is bent, the part of the bending piece 6 close to the bending mold 30 is embedded in the mold groove 301. Figure 3 As shown;

[0068] The cutting structure 5 is connected to the frame 1 through a support seat 51, a cutting machine 50 is installed on the support seat 51, a driving member 2 is installed inside the support seat 51, a sliding plate 2 511 is fixedly connected to the moving end of the driving member 2, the cutting machine 50 is slidably connected to the support seat 51 through the sliding plate 2 511, and approaches or moves away from the limiting structure 3 through the driving member 2;

[0069] In the first state, the part to be bent 6 slides along the mold groove 301 below the bending mold 30 through the feeding structure, and the single sliding length of the part to be bent 6 is the bending length. Figure 4 As shown in the first state diagram;

[0070] In the second state, the abutment plate 211 is close to the bending die 30 through the cylinder 1 201, and the end of the abutment plate 211 close to the bending die 30 is aligned with the bending end of the bending die 30, and the end of the bending piece 6 away from the bending die 30 is embedded in the corresponding embedding groove on the abutment plate 211. Figure 4 In the process, the whole process is the process of transforming the first state diagram into the second state diagram;

[0071] In the third state, the abutment plate 211 bends the to-be-bent portion of the to-be-bent part 6 under the action of the robot arm 20, the driving member 1 and the cylinder 1 201, and the to-be-bent portion is bent in accordance with the mold groove 301 on the bending mold 30. After bending, the abutment plate 211 is separated from the to-be-bent portion. Figure 4 , the second state diagram is transformed into the third state diagram;

[0072] In the fourth state, the feeding structure continues to feed the part to be bent 6. When the part is fed to the required length for cutting, Figure 4 As shown in the fourth state diagram, thereafter, the cutting machine 50 approaches the bending portion of the part to be bent 6 through the driving member 2, and the cutting machine 50 is started to cut the bending portion of the part to be bent 6.

[0073] By setting a limiting structure 3, the limiting structure 3 is set in the form of a bending mold 30 and a mold groove 301, and combined with the abutment plate 211, an embedding groove corresponding to the mold groove 301 is set on the abutment plate 211, and the bending groove formed by the mold groove 301 and the embedding groove corresponds to the shape of the bending part 6 according to the first state to the fourth state. The formed mold groove 301 is adapted to the bending angle, which can realize multi-stage bending of the material. When performing multi-stage bending, the mold groove 301 is used to limit the bending part in the bending process and the section where the bending part 6 is connected to the bending part, so as to improve the bending stability during the simultaneous multi-stage bending process, and solve the problem in the prior art that when the material is simultaneously bent in multiple stages, the bending section of the material is prone to bending deviation, resulting in poor multi-stage bending effect of the material.

[0074] like Figure 2-Figure 4 As shown, the abutment plate 211 is provided with an adapter plate 212 corresponding to the embedding grooves one by one, and a plurality of the adapter plates 212 are integrally formed with the abutment plate 211, and each of the adapter plates 212 is adapted to the corresponding embedding groove;

[0075] In the second state, the connection between the plurality of adapter plates 212 and the abutment plate 211 is located at the first bending section, and is used to support the to-be-bent component 6 .

[0076] By providing a plurality of adapter plates 212 corresponding to the embedded grooves one by one, the adapter plates 212 are used to support the first bending section during bending, thereby improving the stability during the bending process and further reducing the problem of the bending section being easily offset during the bending process, resulting in poor bending effect.

[0077] like Figure 1 , Figure 3-Figure 4As shown, the bending device also includes a positioning structure 4, which is installed with the frame 1 through a base, and includes a lower positioning plate 40 and an upper positioning plate 41, wherein the upper positioning plate 41 is located above the lower positioning plate 40 and is moved closer to or away from the lower positioning plate 40 through a cylinder 2 411;

[0078] The lower positioning plate 40 is slidably connected to the base via a plurality of slide plates 401;

[0079] A driving member 3 is installed inside the base, and the moving end of the driving member 3 drives a plurality of slide plates 401 to drive the lower positioning plate 40 to approach or move away from the bending mold 30;

[0080] The upper positioning plate 41 is provided with a plurality of positioning grooves adapted to the to-be-bent member 6 at one end thereof close to the lower positioning plate 40;

[0081] The surface of the lower positioning plate 40 close to the upper positioning plate 41 is level with the bottom surface of the part to be bent 6;

[0082] In the fifth state, before the cutting structure 5 in the fourth state cuts, the driving member 3 controls the lower positioning plate 40 to be close to the bending portion of the to-be-bent member 6, the upper surface of the lower positioning plate 40 contacts the to-be-bent member 6, the bending portion is located between the lower positioning plate 40 and the upper positioning plate 41, and the cylinder 2 411 drives the upper positioning plate 41 to be close to the lower positioning plate 40, the positioning groove provided on the upper positioning plate 41 contacts the corresponding bending portion, and the bending portion is clamped and positioned, as shown in FIG. Figure 4 As shown in the fourth state diagram and the fifth state diagram.

[0083] By providing the positioning structure 4, the bending part of the to-be-bent part 6 is positioned using the positioning structure 4, 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 to-be-bent parts.

[0084] like Figure 1 As shown, two symmetrically arranged supporting structures 11 are installed on the frame 1, and the two symmetrically arranged supporting structures 11 are used to place the material receiving frame;

[0085] The positioning structure 4 is provided with an inclined blanking plate 42;

[0086] The two supporting structures 11 are located at the inclined lower end of the blanking plate 42;

[0087] In the initial state, the lower positioning plate 40 is located above the blanking plate 42;

[0088] After cutting by the cutting structure 5, the bent part clamped by the positioning structure 4 returns to the initial state under the action of the driving member 3, and 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 along the blanking plate 42 to the receiving frame placed between the two supporting structures 11.

[0089] By providing the unloading plate 42, the collection of the cut materials is facilitated and the whole operation process is simple.

[0090] like Figure 3 As shown, the bending die 30 is detachably connected to the limiting structure 3 via a mounting member 31;

[0091] The mounting member 31 includes two symmetrically arranged mounting plates 311 , and the two mounting plates 311 are provided with a plurality of threaded holes 313 corresponding to each other. The bending die 30 is provided with a plurality of insertion holes 312 .

[0092] The installation part 31 is provided to facilitate the disassembly and replacement of the bending mold 30 . Meanwhile, a plurality of sockets 312 are provided on the bending mold 30 , and the bending mold 30 is plugged in using the sockets 312 , thereby achieving dual stability in the installation of the bending mold 30 .

[0093] like Figure 6-Figure 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, and a flow pipe 102 is integrally formed on the frame 10;

[0094] 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 embedded gap is sealed by a seal, the discharge trough 101 is semi-columnar, and the bottom of the discharge trough 101 is lower than the inner bottom of the frame 10;

[0095] During cutting, the cutting liquid and the clean water used for cooling the metal enter into the collecting frame for collection, flow through the discharge trough 101 , and flow out through the circulation pipe 102 .

[0096] By setting the discharge trough 101 and opening the discharge trough 101 on the frame 1, the bottom of the discharge trough 101 is lower than the inner bottom of the frame 10, which is convenient for the outflow of cutting fluid containing metal chips. At the same time, the circulation pipe 102 can facilitate the installation of the drainage pipe to realize the discharge of the cutting fluid and the clean water used for metal cooling.

[0097] It should be noted that, in the specific use process, the water can be drained quantitatively, and when the water accumulates to a certain depth in the frame 10, it is discharged together, which can achieve a better discharge effect and prevent the problem that the water is shallow and is not conducive to the discharge of debris.

[0098] like Figure 8As shown, the circulation pipe 102 is located on one side of the frame 10 with a rounded corner, and the outer arc of the rounded corner portion 103 contacts the lower end of the discharge trough 101, which further facilitates the discharge of chips from the cutting liquid and the clean water used for metal cooling.

[0099] like Figure 1 , Figure 6 as well as Figure 8-Figure 9 As shown, a stirring structure 22 is installed at the connection portion between the mechanical arm 20 and the chassis 2, and the stirring structure 22 includes a plurality of connecting plates 221, and an elastic brush 222 is provided at one end of each connecting plate 221 away from the mechanical arm 20;

[0100] A plurality of disturbance cavities 223 are formed on the elastic brush 222;

[0101] When the robot arm 20 controls the abutment plate 211 to approach or move away from the bending mold 30 along the feeding direction, the stirring structure 22 moves synchronously in the frame 10 and disturbs the water flow in the frame 10 to reduce the deposition of debris and facilitate the discharge of the water flow in the frame 10. The multiple disturbance chambers 223 can enhance the disturbance effect of the stirring structure 22 on the water flow and further enhance the discharge effect of the water flow in the frame 10.

[0102] Specifically, each of the connecting plates 221 is integrally formed with the corresponding elastic brush 222 . When in use, one end of the elastic brush 222 away from the connecting plate 221 contacts the water flow in the frame 10 .

[0103] It should be noted that the entire device is equipped with a water tank structure for cooling down during metal cutting. This is a prior art and will not be described in detail.

[0104] During operation, step 1: the external feeding structure feeds the part to be bent 6, and the entire device is in the first state. At this time, the part to be bent 6 slides along the mold groove 301 below the bending mold 30 through the feeding structure, and the single sliding length of the part to be bent 6 is the bending length. Figure 4 As shown in the first state diagram;

[0105] Step 2: The entire device moves from the first state to the second state. At this time, the abutment plate 211 approaches the bending die 30 through the cylinder 1 201, and the end of the abutment plate 211 close to the bending die 30 is aligned with the bending end of the bending die 30. The end of the bending piece 6 away from the bending die 30 is embedded in the corresponding embedding groove on the abutment plate 211. Figure 4 In the process, the whole process is the process of transforming the first state diagram into the second state diagram;

[0106] Step 3: The entire device moves from the second state to the third state. At this time, the abutment plate 211 bends the part to be bent of the part 6 to be bent under the action of the robot arm 20, the driving member 1 and the cylinder 1 201. The part to be bent is bent in accordance with the mold groove 301 on the bending mold 30. After bending, the abutment plate 211 is separated from the part to be bent. Figure 4 , the second state diagram is transformed into the third state diagram;

[0107] At the same time, when the robot arm 20 controls the abutment plate 211 to approach or move away from the bending die 30 along the feeding direction, the stirring structure 22 moves synchronously in the frame 10 and disturbs the water flow in the frame 10;

[0108] Step 4: The entire device moves from the third state to the fourth state. At this time, the feeding structure continues to feed the part to be bent 6. When the material is fed to the required length for cutting, the entire device moves from the fourth state to the fifth state. The driving member 3 controls the lower positioning plate 40 to approach the bending portion of the part to be bent 6. The upper surface of the lower positioning plate 40 contacts the part to be bent 6. The bending portion is located between the lower positioning plate 40 and the upper positioning plate 41. The 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 bending portion and clamps and positions the bending portion. Figure 4 As shown in the fourth state diagram and the fifth state diagram;

[0109] Step 5: Finally, the cutting machine 50 approaches the bending part of the part to be bent 6 through the driving member 2, and starts the cutting machine 50 to cut the bending part of the part to be bent 6. After the cutting structure 5 cuts, the positioning structure 4 clamps the cut bending part and returns to the initial state under the action of the driving member 3. 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 along the blanking plate 42 to the receiving frame placed between the two supporting structures 11.

[0110] It should be noted that the mold groove 301 on the bending mold 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 to be bent 6, and can process columnar materials or strip profiles. Figure 4 Columnar embodiment in Figure 5 Bar chart.

[0111] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0112] 1. By setting a limiting structure 3, the limiting structure 3 is set in the form of a bending mold 30 and a mold groove 301, and combined with the abutment plate 211, an embedding groove corresponding to the mold groove 301 is set on the abutment plate 211, and the bending groove formed by the mold groove 301 and the embedding groove is used to limit the bending part in the bending process and the section where the part to be bent 6 is connected to the bending part by the mold groove 301, thereby improving the bending stability during the simultaneous multi-stage bending process, and solving the problem in the prior art that when the material is simultaneously bent in multiple stages, the bending section of the material is prone to bending deviation, resulting in poor multi-stage bending effect of the material.

[0113] 2. By setting a positioning structure 4, the bending part of the bending part 6 to be bent is positioned using the positioning structure 4, 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.

[0114] 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 is convenient for the outflow of cutting fluid with metal chips.
