[0045] First embodiment

[0046] As Figure 1 shown, the first embodiment of the present application discloses an automatic bending device, characterized in that it comprises:

[0047] The upper die assembly 10 comprises a power element 11 and a plurality of upper bending blocks 12, the lower surface of the upper bending block 12 is provided with a protruding upper bending edge / slot 12a, and any upper bending block 12 is vertically lifted under the driving of the power element 11;

[0048] The lower die assembly 20 comprises a base 21 and a plurality of lower bending blocks 22 installed on the base 21 and corresponding to the upper bending blocks 12, the upper surface of the lower bending block 22 is provided with a lower bending slot / edge 22a matched with the upper bending edge / slot 12a;

[0049] Wherein, when the upper bending block 12 is vertically lowered to tightly press the lower bending block 22, the upper bending edge / slot 12a is matched with the lower bending slot / edge 22a.

[0050] Specifically, the automatic bending device of the present embodiment controls the cooperative action of the upper die assembly 10 and the lower die assembly 20, so that the plurality of upper bending blocks 12 can be automatically pressed on the corresponding plurality of lower bending blocks 22 at the same time or in a very short time, and when the upper bending block 12 tightly presses the lower bending block 22, the upper bending edge / slot 12a of the upper bending block 12 is just embedded in the lower bending slot / edge 22a of the lower bending block 22, so that the workpiece placed on the upper surface of the lower bending block 22 is bent and pressed, thereby forming multiple bends at the predetermined position of the workpiece. With the automatic bending device of the present embodiment, the multiple bends of the workpiece can be formed at one time without manual pressing and bending in multiple times, which facilitates the realization of fully automated assembly line operation, greatly saves manpower and resources, and has good practical value.

[0051] Wherein, the power element 11 driving the vertical lifting of the upper bending block 12 can adopt a pneumatic cylinder, which is a pneumatic actuator commonly used in the automobile industry to convert the pressure energy of compressed gas into mechanical energy in pneumatic transmission, and can usually make reciprocating linear motion. The pneumatic cylinder in the present embodiment as a power element can make up-down reciprocating motion, thereby driving the vertical lifting motion of the upper bending block 12 connected thereto. As Figure 1As shown, the cylinder and the upper folding block 12 can be connected through a piston rod, which is a connecting component supporting the piston to work, usually applied in the cylinder movement execution component, and is a frequently moving component with high technical requirements. The power element of the embodiment is not limited to the cylinder, but can also be an oil cylinder or other components with the same power effect.

[0052] Further, the bottom of the piston rod is provided with a mounting plate 14 and a mounting frame 15 connected to the mounting plate 14. The mounting frame 15 can be provided in a hollow T-shaped structure, and correspondingly, as shown in Figure 2 The upper folding block 12 is provided in an I-shaped structure, so that the upper folding block 12 can be inserted into the mounting frame 15 in a straight insertion manner from the side surface. The bottom of the mounting frame 15 supports the upper beam of the upper folding block 12, avoiding the vertical falling of the upper folding block 12, so that the upper folding block 12 and the mounting frame 15 are connected in a detachable manner. When the upper folding block 12 needs to be removed, it can be pulled out from the side surface of the mounting frame 15, which is very flexible and convenient to operate, and provides great convenience for the adjustment and replacement of the upper folding block.

[0053] Further, the side surface of the mounting frame 15 is also provided with a baffle 16, which can be fixed to the side surface of the mounting frame 15 through a horizontal pivot, so that the baffle 16 can rotate in the vertical plane around the horizontal pivot. When the upper folding block 12 needs to be inserted, the baffle 16 is rotated upward, and after the upper folding block 12 is inserted into the mounting frame 15, the baffle 16 is rotated downward, so that the baffle 16 blocks the upper folding block 12 from falling from the side surface. The design of the baffle 16 makes the detachable installation of the upper folding block 12 more convenient and increases the firmness of the installation.

[0054] In the embodiment, the lower die assembly 20 matched with the upper die assembly 10 includes a plurality of lower folding blocks 22, as shown in Figure 3 and Figure 4 As shown, the upper surface edge of any lower folding block 22 is provided with one or more guide pins 23, and correspondingly, the lower surface of the upper folding block 12 is also provided with guide holes 17 matched with the guide pins 23.

[0055] In addition, the lower folding block 22 of the embodiment is also provided with a positioning component 24, which can be a positioning pin or a positioning hole, matched with the positioning hole or the positioning pin on the base 21, so as to accurately position and install the lower folding block 22 on the base, avoiding position deviation.

[0056] As an optional embodiment of this method, the base 21 also supports a conveyor plate for placing the workpiece to be processed. Typically, the conveyor plate has bending positioning holes for the lower bending block 22 to pass through, placing the workpiece at its bending position on the lower bending groove / edge 22a of the lower bending block 22. When the upper bending block 12 is pressed down, a bend is formed precisely at the bending position of the workpiece. In this embodiment, the conveyor plate can be equipped with multiple bending positioning holes corresponding to the bending positions as needed, allowing the workpiece to be bent into shape in one operation. Furthermore, the conveyor plate can also be provided with side grooves to facilitate operator handling of the conveyor plate.

[0057] Furthermore, the conveyor plate is also provided with a conveyor plate positioning hole. Correspondingly, the base 21 is provided with a base positioning pin that cooperates with the conveyor plate positioning hole. The conveyor plate positioning hole and the base positioning pin together accurately fix the conveyor plate on the base 21 to prevent positional deviation.

[0058] In addition, the conveyor plate is also equipped with a product positioning pin. The product positioning pin helps to accurately fix the product to be processed on the conveyor plate. Then the conveyor plate is placed on the base 21 for processing. In order to avoid the product positioning pin from colliding with the upper bending block and hindering the pressing, a groove can be provided on the lower surface of the upper bending block 12 to avoid the product positioning pin.

[0059] In a preferred embodiment of this method, a heating device can be installed inside the base 21 to heat the workpiece during bending, thereby accelerating the bending speed and achieving a better bending effect. Accordingly, when a heating device is installed inside the base, a heat insulation device needs to be installed on the surface of the base 21 to prevent damage to equipment or personnel caused by high temperatures.

[0060] It should be noted that the lower surface of the upper folding block 12 in this embodiment is provided with a protruding upper folding blade / groove 12a, and the upper surface of the lower folding block 22 is provided with a matching lower folding groove / blade 22a. Those skilled in the art can easily conceive that the upper folding blade / groove can also be an upper folding groove, and the lower folding groove / blade can also be adjusted to a lower folding blade accordingly, which can also achieve the effect of pressing and folding. Further details will not be elaborated here.

[0061] Second Embodiment

[0062] like Figure 5 As shown, the second embodiment of the present invention discloses an automatic bending device, including: a housing 1, a base plate 2 disposed at the bottom of the housing 1, a linear guide rail 3 mounted on the base plate 2, a control component 4 disposed inside the housing, and an automatic bending device 5 disposed on the linear guide rail. According to the first embodiment of the present invention, the automatic bending device 5 includes:

[0063] The upper die assembly 10 comprises a power element 11 and a plurality of upper bending blocks 12, the lower surface of the upper bending block 12 is provided with a protruding upper bending blade / groove 12a, and any upper bending block 12 is vertically lifted under the driving of the power element 11;

[0064] The lower die assembly 20 comprises a base 21 and a plurality of lower bending blocks 22 installed on the base 21 and corresponding to the upper bending blocks 12, the upper surface of the lower bending block 22 is provided with a lower bending groove / blade 22a matched with the upper bending blade / groove 12a;

[0065] When the upper bending block 12 is vertically lowered to tightly press the lower bending block 22, the upper bending blade / groove 12a is matched with the lower bending groove / blade 22a.

[0066] As can be seen from Figure 5 The base 21 of the automatic bending device 5 can be placed on the linear guide rail 3 so as to be driven by the linear guide rail to transport the finished product to the downstream of the production line. Thus, the pipeline operation can be realized, and the production efficiency is greatly improved compared with manual operation.

[0067] More specifically, the control assembly 4 can comprise a time relay 4a for controlling the processing time, a temperature controller 4b for controlling the heating temperature, and a switching element 4c. Under the cooperation of various control elements, after starting the bending work process, the upper bending block 12 is vertically lowered to press the corresponding lower bending block 22, and stays for a predetermined length of time under suitable temperature conditions, so as to quickly obtain the best bending shape, thereby improving the production efficiency and further improving the bending quality.

[0068] In addition, the outer surface of the casing 1 can also be provided with a man-machine interactive display device, which is convenient for the operator to input setting parameters and other control information, and can also display the working state of the machine in real time, so as to facilitate the operator to monitor in real time and reduce the failure probability.

[0069] The automatic bending device disclosed in the embodiment utilizes the automatic bending device of the first embodiment to perform automatic bending operation, and controls the cooperation of the upper die assembly 10 and the lower die assembly 20 to enable the plurality of upper bending blocks 12 to be automatically pressed on the corresponding plurality of lower bending blocks 22 at the same time or in a very short time. When the upper bending block 12 tightly presses the lower bending block 22, the upper bending blade / groove 12a of the upper bending block 12 is embedded in the lower bending groove / blade 22a of the lower bending block 22. In this way, the product to be processed placed on the upper surface of the lower bending block 22 is bent and pressed, so as to be bent at multiple bending positions. The automatic bending device of the embodiment can make the product to be processed be formed at multiple bending positions at one time, without manual pressing and bending for multiple times, so as to facilitate the realization of fully automatic pipeline operation, greatly save manpower and material resources, and have good practical value.

[0070] The relevant components of the automatic bending device of the present embodiment are similar to those of the first embodiment, and will not be described here.

[0071] Third embodiment

[0072] As shown in Figure 6 , the third embodiment of the present application discloses an automatic bending method for part bending using the above-mentioned automatic bending device, comprising the following steps:

[0073] Step S601, placing the plurality of bending positions of the workpiece to be processed against the plurality of target lower bending grooves / edges of the target lower bending blocks;

[0074] Step S602, controlling the power element to move to drive the plurality of target upper bending blocks corresponding to the plurality of target lower bending blocks to descend vertically in sequence until the upper bending edge / groove of any target upper bending block is pressed into the lower bending groove / edge of the corresponding target lower bending block;

[0075] Step S603, controlling the plurality of target upper bending edges / grooves to stay for a predetermined length of time;

[0076] Step S604, controlling the power element to move to drive the plurality of target upper bending blocks to ascend vertically in sequence, so that the upper bending edge / groove of the target upper bending block is separated from the lower bending groove / edge of the corresponding target lower bending block.

[0077] Specifically, the base carries a conveying plate for placing the workpiece to be processed, and the conveying plate is provided with bending positioning holes; in step S601, the plurality of bending positions of the workpiece to be processed are placed against the plurality of target lower bending grooves / edges of the target lower bending blocks, as shown in Figure 7 , specifically:

[0078] Step S6011, fixing the workpiece to be processed on the conveying plate, and the plurality of bending positions of the workpiece to be processed correspond one-to-one to the bending positioning holes on the conveying plate;

[0079] Step S6012, placing the conveying plate with the workpiece to be processed fixed thereon on the base, and adjusting the positions of the target lower bending blocks installed on the base, the plurality of target lower bending blocks passing through the bending positioning holes to align the plurality of bending positions of the workpiece to be processed with the lower bending grooves / edges of the target lower bending blocks.

[0080] In practice, according to actual needs, a plurality of lower bending blocks can be first installed on the base, for example, when 9 bends are needed to be processed on the FPC, 9 lower bending blocks can be installed at the designated positions of the base; then the product to be processed can be first placed on the conveying plate, the plurality of predetermined bending positions of the product to be processed are made to correspond to the bending positioning holes of the conveying plate one by one through the positioning component, and then the conveying plate on which the product to be processed is placed is placed on the base, so that the lower bending blocks on the base protrude through the bending positioning holes of the conveying plate, thereby placing the plurality of predetermined positions of the product to be processed corresponding to the lower bending grooves / edges. It should be noted that the above process can continuously adjust the positions of the lower bending blocks so that the lower bending blocks can correspond to the bending positioning holes of the conveying plate one by one.

[0081] In step S602, the plurality of target upper bending blocks can be controlled to vertically descend one by one in the first order and at the preset frequency by using a timing device or through a software program. After the bending is completed, in step S604, the plurality of target upper bending blocks are controlled to vertically ascend one by one in the second order and at the preset frequency, and the second order is the same as the first order. Sequential bending instead of simultaneous pressing operation can avoid exceeding the stretching capacity of the area between each bend of the product, thereby avoiding the risk of product breakage. The preset frequency can be optimally set according to practical experience to achieve the best work efficiency.

[0082] The automatic bending method of the embodiment realizes automatic production in a pipeline, has high processing efficiency and good bending quality, and has high practical value.

[0083] In summary, the automatic bending device, equipment and method disclosed by the present application can realize multiple bending at a time under the cooperation of the mechanical structures of the upper die assembly and the lower die assembly, can realize fully automatic bending operation, realizes automatic production in a pipeline, has high processing efficiency, saves manpower and material resources, and has high practical value.
