Description

Technical Field

[0001] The present invention relates to the technical field of metal product processing dies, and more particularly to a multifunctional metal part continuous forming device and a continuous processing method thereof. Background Art

[0002] In the field of metal product processing, especially in the production process involving complex-shaped parts, the application of molds is of vital importance. In the existing technology, for products that need to complete forward processing, bending forming and U-shaped bending forming in sequence, three sets of independently set molds are usually used, namely forward molds, bending molds and U-shaped bending molds. This traditional processing mode requires that the products be processed in sequence at three independent workstations, and each workstation is usually equipped with a dedicated processing equipment; specifically, the multiple products on the forward mold are mostly tilted. In order to adjust the posture of the product before bending, an operator is required to be arranged in front of each device to be responsible for the loading, product posture adjustment and unloading operations of the workstation.

[0003] This step-by-step, decentralized production method can still meet production needs when the product variety is simple and the output is low. However, with the growing market demand for products, especially when the product output increases significantly, this traditional model has exposed significant drawbacks.

[0004] First, the three independent workstations and equipment result in a large production area, high equipment investment and maintenance costs. Secondly, each workstation needs to be equipped with a dedicated operator. When the output increases, the number of operating workers required also increases sharply. Not only does the labor cost rise significantly, but it is also difficult to recruit, train and manage a sufficient number of skilled workers in a short period of time, resulting in labor becoming a key bottleneck restricting the improvement of production efficiency. In addition, the management and coordination of multiple workstations, multiple equipment, and multiple personnel is complex, and it is difficult to unify operating standards. Problems such as product damage and unstable processing accuracy caused by human factors (such as operating errors, fatigue, lack of concentration, etc.) also occur frequently, making it difficult to continuously and reliably guarantee product quality. At the same time, transportation between workstations may also introduce additional errors and time losses, further affecting the overall production efficiency and product consistency.

[0005] Therefore, the existing technology's multi-station, multi-equipment, and multi-personnel separate processing model has become inefficient, costly, and difficult to manage in the face of growing production needs. A more integrated, automated, and efficient production solution is urgently needed to overcome the above technical problems. Summary of the Invention

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the following will be a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work shall fall within the scope of protection of the present invention.

[0037] Example 1:

[0038] A multifunctional metal parts continuous forming device according to a preferred embodiment of the present invention is as follows: Figure 1-2 As shown, the apparatus comprises a lower base plate 01, which serves as a base support. Lower base plate 01 is provided with a sequentially arranged feed module 11 for punching a material strip 02 containing semi-finished products 22 and loading the products 22; a posture adjustment module 12 for adjusting the processing posture of the products 22; a bending module 13 for bending the opposite ends of the products 22; and a U-shaped bending module 14 for bending the opposite sides of the products 22. Lower base plate 01 is also provided with a pick-up assembly 15 for sucking the products 22, and a transfer assembly 16 for moving the pick-up assembly 15 between the sequential feed module 11, the rotating platform 123, the bending module 13, and the U-shaped bending module 14.

[0039] This device integrates the processes of forward feeding, posture adjustment, bending, and U-shaped bending into one device through the use of a transfer component and a material-retrieving component. This transforms the originally dispersed and manually dependent complex processing flow into a continuous, efficient, and low-cost automated production. Products can be quickly and automatically transferred between various workstations, greatly shortening the production cycle. The automated posture adjustment, material-retrieving, and transfer processes are precisely controllable, facilitating subsequent product processing and avoiding problems such as inaccurate posture adjustment and pick-and-place errors that may arise from manual operation. This ensures that the product is in the same state before processing at each workstation.

[0040] In this embodiment, the device also includes an upper substrate 03 corresponding to the lower substrate 01, and a second lifting component (not shown in the figure) that drives the upper substrate 03 closer to or away from the lower substrate 01. The second lifting component can be a hydraulic cylinder or a drive cylinder or a screw linear drive module in the prior art.

[0041] Forwarding module 11:

[0042] The forwarding module 11 is mainly used to process the metal strip 02 with semi-finished products.

[0043] like Figure 3As shown, the material strip 02 includes a substrate 21; a plurality of semi-finished products 22 have been pre-punched or processed on the substrate 21; the two ends of the semi-finished products 22 are connected to the substrate 21 only by a thin connecting strip 23; in this embodiment, the semi-finished product 22 is an unfolded plan view, and in order to further improve the utilization rate of the substrate 21, the plurality of semi-finished products 22 are generally tilted and laid flat on the substrate 21.

[0044] like Figure 4 As shown, the forwarding module 11 includes a first lower mold assembly 111 fixedly mounted on the lower base plate 01, and a first upper mold assembly 112 fixedly mounted on the upper base plate 03 and corresponding to the first lower mold assembly 111; optionally, the first upper mold assembly 112 can also be independently movably mounted above the first lower mold assembly 111. The first lower mold assembly 111 is provided with a material discharge position 113 for placing the feed belt 02; the first upper mold assembly 112 is provided with a plurality of punching heads 114 for punching connecting belts 23; the first lower mold assembly 111 is provided with a plurality of avoidance grooves 115 corresponding one-to-one to the punching heads 114; the plurality of connecting belts 23 all correspond one-to-one to the openings of the avoidance grooves 115, ensuring that the downward path of the plurality of punching heads is unobstructed, and the precise cooperation of the upper and lower molds ensures that the punching positions are accurate.

[0045] When the second lifting assembly drives the upper baseplate downward toward the lower baseplate, multiple punching heads simultaneously and precisely cut away the corresponding connecting strips, separating individual semi-finished products from the material strip, completing preliminary processing and forming independent products ready for transfer. The first lower die assembly features a clearance slot corresponding to each punching head, allowing it to pass smoothly as it descends.

[0046] Posture adjustment module 12

[0047] The posture adjustment module 12 is located after the forwarding module 11 and is used to adjust the posture of the product separated from the material belt to adapt to the subsequent bending and U-shaped forming processes.

[0048] like Figure 5 As shown, the posture adjustment module 12 includes a base plate 121 fixedly connected to the lower base plate 01; the base plate 121 is rotatably connected to a U-shaped mounting frame 122 via a rotary bearing, which can realize the horizontal rotation of the U-shaped mounting frame 122; the posture adjustment module 12 is also equipped with a rotating platform 123 at the opening at the upper end of the U-shaped mounting frame 122, on which the product can be placed for positioning; the two ends of the rotating platform 123 are rotatably connected to the two supporting legs of the U-shaped mounting frame 122 via two rotating shafts 124;

[0049] The posture adjustment module 12 also includes a flipping assembly 125 that drives the rotating platform 123 to rotate longitudinally to turn the product 22 over, and an angle adjustment assembly 126 that drives the rotating platform 123 to rotate horizontally to adjust its horizontal angle, which can achieve more precise and multi-degree-of-freedom posture adjustment of the workpiece; wherein, the flipping assembly 125 ((for example, a rotating motor in the prior art)) is fixed on any supporting foot, and its output end is fixedly connected to the corresponding rotating shaft 124; it drives the rotating platform to rotate longitudinally 180° around its own axis to achieve the product flipping operation.

[0050] In this embodiment, the angle adjustment assembly 126 is used to drive the entire U-shaped mounting frame (together with the rotating platform) to rotate horizontally to adjust the angle of the product relative to the processing coordinate system. In this embodiment, the angle adjustment assembly 126 includes a telescopic cylinder 1261 disposed on one side of the U-shaped mounting frame 122. The output end of the telescopic cylinder 1261 is rotatably connected to the U-shaped mounting frame 122 via a connector 1262, and the cylinder end is fixedly connected to the base plate 121 via an angle adjuster 1263. In this embodiment, the angle adjuster 1263 can be a universal joint or a specific angle locking mechanism in the prior art. After the telescopic cylinder 1261 is adjusted to a preset angle via the telescopic angle adjuster 1263, the length of its output push rod is controlled to drive the horizontal rotation of the U-shaped mounting frame 122. By controlling the travel of the telescopic cylinder and the angle adjuster, the U-shaped mounting frame (and the product on the rotating platform) can be precisely rotated to the desired angle, improving the device's adaptability to different product designs and processing requirements.

[0051] Furthermore, the U-shaped mounting frame 122 has a first state for loading the product 22 before the posture is adjusted during the horizontal rotation process, and a second state for waiting for the product 22 after the posture is adjusted; in this embodiment, the first state is an inclined state that is the same as the initial loading state of the product 22, which is convenient for directly placing the semi-finished product 22 (first state) that is usually in an inclined state coming from the forwarding module 11, and changing it into a horizontal vertical or horizontal correction state (second state) through adjustment to meet the processing requirements of subsequent processes; for precise positioning, the angle adjustment assembly 126 also includes two limit blocks 1264 arranged on the other side of the U-shaped mounting frame 122; of the two limit blocks 1264, one limit block 1264 abuts against the U-shaped mounting frame 122 in the first state, and the other limit block abuts against the U-shaped mounting frame 122 in the second state; the two limit blocks 1264 correspond to the initial loading state and the adjusted waiting state of the product, respectively. They can ensure that the U-shaped mounting bracket stops accurately and reliably when rotating to these two key positions, avoiding angular deviation and providing a precise starting position for subsequent processes;

[0052] Optionally, the posture adjustment module 12 further includes a support plate 127 horizontally disposed below the rotating platform 123, and a first lifting assembly 128 for driving the support plate 127 to move along the Z-axis. In this embodiment, the first lifting assembly 128 includes two Z-direction slide rails provided on the opposite inner sides of the two supporting legs of the U-shaped mounting frame 122, two sliding blocks slidably connected to the two Z-direction slide rails, and a lifting motor or telescopic cylinder for driving the support plate 127 to move along the two Z-direction slide rails. The two sliding blocks are fixedly connected to both ends of the support plate 127.

[0053] Furthermore, movable grooves 1232 are provided on both sides of the rotating platform 123 and are connected to the product placement groove 1231 therein; a locking block 1233 is movably provided in the movable groove 1232 and engages with the outer edge of the product, and a first reset elastic member (not shown in the figure) provides the locking block 1233 with a tendency to move toward the product; Figure 6 As shown, the support plate 127 is vertically provided with an unlocking plug 1271 that is inserted into the movable groove 1232 to release the locking block 1233 from securing the product. In the initial state, the locking block 1233 is maintained in a protruding position toward the product placement groove 1231 on the rotating platform under the action of the first return elastic member. When it is necessary to place or remove a product, the first lifting assembly 128 is simply controlled to drive the unlocking plug 1271 on the support plate 127 into the movable groove 1232 on the rotating platform 123. The first return elastic member is compressed into a non-free state, causing the locking block 1233 to move away from the product placement groove 1231, thereby releasing the product. When it is necessary to securely position the product in the product placement groove, the first lifting assembly 128 is controlled to drive the unlocking plug 1271 on the support plate 127 away from the rotating platform. The first return elastic member is not affected by external pressure and returns to a free state, allowing the locking blocks on both sides to continue clamping the product, further improving positioning accuracy.

[0054] The posture adjustment module 12 integrates multiple functions such as flipping, horizontal angle adjustment, precise positioning and auxiliary support products. It can accurately, reliably and automatically adjust semi-finished products from the material strip and with different postures to the optimal state required for subsequent processing, ensuring the smooth, efficient and high-precision operation of the entire continuous molding process.

[0055] Bending module 13

[0056] The bending module is used to bend the two ends of the product after the posture is adjusted.

[0057] like Figure 7As shown, the bending module 13 includes a second lower mold assembly 131 fixedly set on the lower base plate 01, and a second upper mold assembly 132 fixedly set on the upper base plate 03 and corresponding to the second lower mold assembly 131; optionally, the second upper mold assembly 132 can also be independently movably set above the second lower mold assembly 131.

[0058] An upper pressing block 133 is provided on the lower surface of the second upper mold assembly 132; the two end edges of the upper pressing block 133 correspond to the inner side surfaces of the bends at both ends of the product; a first groove 134 is provided on the second lower mold assembly 131; first bending inserts 135 are fixedly installed at both ends of the first groove 134; the two first bending inserts 135 correspond to and support the two ends of the product 22 respectively, and a first forming groove 136 for inserting the upper pressing block 133 is provided between the two first bending inserts 135; a lower pressing block 137 is movably provided in the first forming groove 136 to cooperate with the upper pressing block 133 to press and position the middle part of the product 22, and a first elastic top that drives the lower pressing block 137 to move in and out of the first forming groove 136 along the Z axis The material assembly 138 can not only eject the product or the lower pressure block after the bending is completed, but also drive the pressure block to automatically reset, which is convenient for the next workstation to take the material or the repeated operation of the current workstation, thereby improving the degree of automation and efficiency. The upper edge of the first bending insert 135 facing the lower pressure block 137 is provided with a first bending portion 1351 that cooperates with the bending part of the end of the product 22. In this embodiment, the first bending portion 1351 can be a rotating shaft rotatably connected to the first bending insert 135, and at least a part of the rotating shaft protrudes outside the first bending insert 135 and contacts the product 22; the first bending portion 1351 can also be rotatably formed into an arc-shaped protrusion or a right-angle protrusion on the outer edge of the first bending insert 135.

[0059] The lower pressing block and the upper pressing block cooperate to press the middle part of the product into position before bending, which can prevent the product from shifting or rotating during the bending process, ensuring the accuracy and quality of the bending, and at the same time drive the product to punch downward into the first forming groove 136, so that the two ends of the product are bent respectively with the cooperation of the two first bending parts.

[0060] The reliable middle pressing and clamping and the flexible first bending part design in the bending module 13 can efficiently, accurately and consistently bend the two ends of the product with adjusted posture, laying a good foundation for the subsequent U-shaped bending forming process.

[0061] U-shaped bending forming module 14

[0062] The U-shaped bending module is used to bend the two sides of the product to form a U-shaped structure.

[0063] like Figure 8As shown, the U-shaped curved forming module 14 includes a third lower mold assembly 141 fixedly set on the lower base plate 01, and a third upper mold assembly 142 fixedly set on the upper base plate 03 and corresponding to the third lower mold assembly 141; optionally, the third upper mold assembly 142 can also be independently movably set above the third lower mold assembly 141.

[0064] The third upper die assembly 142 is provided with a vertically downward punching head 143 and a second reset elastic member 144 that provides elastic force to the punching head 143. The second reset elastic member 144 is a spring that is vertically accommodated in the third upper die assembly 142 and is used to provide a rebound force to the punching head 143 after the punching is completed, so that it can automatically rebound to its original shape after the punching is completed, so as to facilitate the next process (such as taking the material). One end of the second reset elastic member 144 is fixedly connected to the third upper die assembly 142, and the other end is fixedly connected to the upper end of the punching head 143. The third lower die assembly 141 is provided with a second groove 145; the second groove 145 is provided on both sides thereof. A second bending insert 146 is fixedly installed; the two second bending inserts 146 correspond to and support the two side edges of the product 22 respectively, and a second forming groove 147 for the punch head 143 to be inserted is provided between the two second bending inserts 146; a movable block 148 is movably provided in the second forming groove 147 to cooperate with the punch head 143 to press and position the middle part of the product 22, and a second elastic lifting component 149 that drives the movable block 148 to move in and out of the second forming groove 147 along the Z axis; the second bending insert 146 has an upper edge facing the movable block 148 on one side thereof. A second bending portion 1461 is provided that is bent in cooperation with the bending portion of the side surface of the product 22.

[0065] While cooperating with the punch head 143 for press-fitting and positioning, the movable block 148 also drives the product downward into the second forming groove 147, thereby forcing centering and firmly clamping the product. This effectively prevents displacement or rotation of the product during the bending process, thereby ensuring bending accuracy. In this embodiment, the second bending portion 1461 can also be configured as a rotating shaft rotatably connected to the second bending insert 146, with at least a portion of the rotating shaft protruding from the second bending insert 146 to contact the product 22. The second bending portion 1461 can also be formed as an arc-shaped protrusion or a right-angled protrusion on the outer edge of the second bending insert 146.

[0066] The movable block and the punch head cooperate to press the center of the product into position, while simultaneously driving the product downward into the second forming groove 147. This causes the two sides of the product to bend in cooperation with the two second bending portions 1461, forming a U-shaped interior. The second elastic lifting assembly can lift the movable block after bending is complete, facilitating material removal.

[0067] It is worth noting that the working surface of the forwarding module 11 , the working surface of the posture adjustment module 12 , the working surface of the bending module 13 and the working surface of the U-shaped bending module 14 are all on the same straight line and at the same height.

[0068] Retrieving assembly 15 and transplanting assembly 16

[0069] like Figure 2 As shown, in this embodiment, the material picking assembly 15 includes at least one cantilever 151. The free end of the cantilever 151 is provided with a plurality of suction cups 152; the suction cups can adopt vacuum suction cups or electromagnetic adsorption devices in the prior art for picking up and placing products. The transfer assembly 16 is a multi-degree-of-freedom manipulator or linear transmission mechanism in the prior art (such as a gantry manipulator, a SCARA manipulator or a belt / chain conveyor with a transfer station), and the cantilever 151 is fixedly connected to the end of the manipulator or the slider of the linear transmission mechanism; the transfer assembly 16 can drive the material picking assembly to move accurately and quickly between the working areas of the forwarding module, the posture adjustment module (rotating platform), the bending module and the U-shaped bending forming module, thereby realizing the automatic flow of products and continuous processing of products without manual participation, low cost and high yield rate.

[0070] Example 2:

[0071] The present invention also provides a continuous processing method of a multifunctional metal piece continuous forming device, which uses a multifunctional metal piece continuous forming device as described in the first embodiment, and includes the following steps:

[0072] Step 1: Forward processing and preliminary separation.

[0073] The material strip containing semi-finished products is placed on the unloading position of the forwarding module. The device is activated, and the upper base plate is lowered by the second lifting assembly. The punching head of the first upper die assembly cuts off the connecting strip, separating the individual semi-finished products from the material strip to form the products to be transferred, making it easier for the retrieving assembly to directly remove the materials. The upper base plate then rises and resets. This completes the initial processing of the individual products and forms the products to be transferred.

[0074] Step 2: Adjust product posture.

[0075] The transfer component drives the picking component to move to the bottom of the forward module to pick up the product that has just been separated. The transfer component moves the product to the rotating platform of the posture adjustment module and places it. The posture adjustment module performs the adjustment action: first, the angle adjustment component (such as a telescopic cylinder) drives the U-shaped mounting frame and the rotating platform to rotate, and adjusts the product to a preset horizontal angle (for example, from an inclined state to a horizontal state); then, the flipping component drives the rotating platform to rotate around its own axis to flip the product so that its posture fully meets the requirements of the subsequent bending process; after the adjustment is completed, the first lifting component can appropriately adjust the height of the support plate to support the flipped product, so that the picking component can pick up the material.

[0076] Step 3: Bend both ends.

[0077] The transplanting assembly drives the picking assembly again to pick up the product with adjusted posture, and moves it precisely to the working area of the bending module (above the first groove). The picking assembly releases the product. The second upper mold assembly descends, and the upper pressure block is inserted into the first forming groove. The lower pressure block, under the action of the first elastic lifting assembly or synchronously descends, presses the middle part of the product. The upper pressure block continues to press down, pushing the two ends of the product against the first bending part of the first bending insert, completing the bending of the two ends. The upper pressure block and the second upper mold assembly rise and reset, and the first elastic lifting assembly lifts the lower pressure block to facilitate material removal.

[0078] Step 4: U-shaped bending.

[0079] The transplanting assembly drives the picking assembly to pick up the product with both ends bent, and moves it precisely to the working area of the U-shaped bending forming module (above the second groove). The picking assembly releases the product. The third upper die assembly descends (or only the punch head descends), the punch head is inserted into the second forming groove, and the movable block descends synchronously under the action of the second elastic ejection assembly to press the middle part of the product. The punch head impacts downward under the action of the second reset elastic member (or directly by the driving mechanism), pushing the two sides of the product to press against the second bending part of the second bending insert to form a U-shaped structure. The punch head and the third upper die assembly rise and reset, and the second elastic ejection assembly lifts the movable block to facilitate material removal.

[0080] Step 5: Finished product output.

[0081] The transfer component drives the material taking component to pick up the final product that has completed the U-shaped bending and transport it to the completion processing area (such as a collection box, a conveyor belt or the entrance of the next process).

[0082] Throughout the entire processing process, the movements of each module (such as upper substrate lifting, angle adjustment, flipping, punching, bending, and U-bending) as well as the movement of the transplanting and retrieving components are precisely coordinated and controlled by a central control system on a background computer (such as a PLC or industrial computer) to ensure that each step is carried out in an orderly and efficient manner.

[0083] By integrating multiple processing stations into a single device and incorporating automated posture adjustment, material removal, and transfer systems, this invention enables continuous automated processing of metal parts, from forward feeding, posture adjustment, bending, to U-bending. This not only significantly improves production efficiency and product quality consistency, but also significantly reduces production costs and management complexity. It is particularly suitable for mass production of complex metal parts and has broad application prospects.

[0084] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
