Description

Technical Field

[0001] This utility model relates generally to the technical field of container manufacturing equipment, and more specifically to an automatic sheet metal forming equipment. Background Technology

[0002] As a key load-bearing component in the structural system, the forming quality of the container roof directly affects the overall structural strength, deformation resistance, and service life. Currently, the mainstream roof reinforcement forming technologies mainly include three routes: traditional multi-stage pressing, integral drawing forming, and continuous roll forming. The traditional multi-stage pressing process has technical bottlenecks. This process uses a single-wave sequential pressing method, forming the reinforcement structure step by step through a pressing mold. After each wave is pressed, manual positioning, transfer, and repeated clamping of the sheet material are required, resulting in a long overall production cycle, low automation integration, and limited production efficiency.

[0003] Therefore, there is a need to provide an automatic sheet metal forming machine to at least partially solve the above problems. Utility Model Content

However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0019] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art.

[0020] It should be understood that the terminology used herein is intended only to describe particular embodiments and is not intended to limit the scope of the invention. The singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. When the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0021] The ordinal numbers such as "first" and "second" used in this utility model are merely identifiers and do not have any other meaning, such as a specific order. Furthermore, for example, the term "first component" does not imply the existence of a "second component," and the term "second component" does not imply the existence of a "first component." It should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," and similar expressions used in this utility model are for illustrative purposes only and are not intended to be limiting.

[0022] The terms “center,” “parallel,” “perpendicular,” “aligned,” and “symmetrical” used in this invention do not have to be precise, but can include typical engineering tolerances.

[0023] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0024] As a key load-bearing component in the structural system, the forming quality of the container roof directly affects the overall structural strength, deformation resistance, and service life. Currently, the mainstream roof reinforcement forming technologies mainly include three routes: traditional multi-stage pressing, integral drawing forming, and continuous roll forming. Traditional multi-stage pressing has technical bottlenecks. This process uses a single-wave sequential pressing method, forming the reinforcement structure step by step through a pressing mold. After each wave is pressed, manual or semi-automatic sheet positioning, transfer, and repeated clamping are required, resulting in dispersed processes, numerous operational steps, long overall production cycle time, low automation integration, and limited production efficiency. Furthermore, when the raw material has initial unevenness (such as warping or wavy edges), the sheet is difficult to smoothly enter the mold and achieve precise positioning, easily causing forming deviations or equipment damage. Therefore, when implementing automated production, an additional leveling process must be configured, increasing equipment investment and process complexity, affecting continuous production efficiency and manufacturing cost control.

[0025] To at least partially solve the above-mentioned technical problems, this utility model provides an automatic sheet metal forming device. See below. Figures 1 to 11 The examples shown provide a detailed description of the automatic sheet metal forming equipment according to the present invention.

[0026] See Figures 1 to 4 This utility model provides an automatic sheet metal forming equipment. The automatic sheet metal forming equipment includes a forming device 100, a feeding device 110, a discharge positioning device 150, and a control device.

[0027] The forming apparatus 100 has a feed side 103 and a discharge side 104 spaced apart along the front-rear direction Dfb of the forming apparatus 100. During the process of the sheet 195 moving from the feed side 103 to the discharge side 104, the forming apparatus 100 performs forming processing on the sheet 195.

[0028] The feeding device 110 is correspondingly disposed on the infeed side 103. The feeding device 110 includes a feeding support assembly 111, a side positioning assembly 119, and a pushing assembly 134. The feeding support assembly 111 is used to support the sheet metal 195 to be processed. The side positioning assembly 119 is connected to the feeding support assembly 111 and is used to position the sheet metal in the left-right direction Dlr of the forming device 100. The pushing assembly 134 is connected to the feeding support assembly 111 and is used to drive the sheet metal to move towards the discharge side 104 in multiple strokes.

[0029] The discharge positioning device 150 is correspondingly disposed on the discharge side 104. The discharge positioning device 150 includes a discharge bearing assembly 151 and a plurality of rear positioning assemblies 154. The discharge bearing assembly 151 is used to support the sheet metal. The rear positioning assemblies 154 are connected to the discharge bearing assembly 151. The plurality of rear positioning assemblies 154 are arranged at intervals along the front-rear direction Dfb so as to position the sheet metal 195 when it moves to different positions along the front-rear direction Dfb toward the discharge side 104.

[0030] The control device is connected to the forming device 100, the feeding device 110 and the discharge positioning device 150, so as to control the operating status of the forming device 100, the feeding device 110 and the discharge positioning device 150.

[0031] According to an embodiment of the present invention, an automatic sheet metal forming equipment is provided with a feeding device 110 on the feeding side 103 of the forming device 100. A feeding support assembly 111 carries the sheet metal 195 to be processed. A side positioning assembly 119 positions the sheet metal along the left-right direction Dlr. A pushing assembly 134 drives the sheet metal to gradually move towards the discharge side 104 to accommodate multiple forming processes. An discharge positioning device 150 is provided on the discharge side 104 of the forming device 100. A discharge support assembly 151 supports the processed portion of the sheet metal. Multiple rear positioning assemblies 154 sequentially position the sheet metal 195 at corresponding positions along the front-back direction Dfb. This means that after each movement of the sheet metal 195 by the pushing assembly 134, the corresponding rear positioning assembly 154 positions the sheet metal 195 in place. By controlling the forming device 100, the feeding device 110, and the discharge positioning device 150, automatic feeding, positioning, and forming can be achieved. By adopting the above technical solution, the sheet metal 195 can be automatically moved and positioned during the pressing process of the sheet metal by the pressing device 100, making the process more concentrated and continuous, which is conducive to shortening the production cycle and thus improving the degree of automation integration and production efficiency.

[0032] See Figure 3 and Figure 4 The forming device 100 described above includes an upper mold 101 and a lower mold 102. Before the upper mold 101 and the lower mold 102 close, the upper surface of the feeding support assembly 111 is usually flush with or substantially flush with the upper surface of the lower mold 102. During the movement of the sheet metal 195 from the feeding side 103 to the discharging side 104, the portion of the sheet metal 195 between the upper mold 101 and the lower mold 102 can complete one forming process after the upper mold 101 and the lower mold 102 close once. If the sheet metal 195 needs to be formed multiple times, the sheet metal 195 needs to be moved multiple times by the pushing assembly 134. Accordingly, the closing cycle of the upper mold 101 and the lower mold 102 is after each movement of the sheet metal 195. Before each movement of the sheet metal 195, the upper mold 101 and the lower mold 102 separate. The forming device 100 can also be referred to as a press.

[0033] See Figure 9In some embodiments, the loading and supporting assembly 111 includes a base member 112 and a plurality of loading and supporting members 113. The loading and supporting members 113 are connected to the upper part of the base member 112. The plurality of loading and supporting members 113 are arranged at intervals along the left-right direction Dlr. In the plane perpendicular to the vertical direction Dve of the forming device 100, the orthographic projection of the loading and supporting members 113 extends along the front-back direction Dfb. Here, the base member 112 serves as the mounting base for the loading and supporting members 113. The loading and supporting members 113 are used to directly support the plate 195. By arranging the loading and supporting members 113 at intervals, the contact area between the loading and supporting assembly 111 and the plate 195 can be reduced, thereby reducing wear on the plate 195 and also reducing the resistance to movement of the plate 195. Furthermore, since the orthographic projection of the feeding support member 113 extends along the front-to-back direction Dfb in the plane perpendicular to the vertical direction Dve of the forming device 100, the resistance experienced by the plate 195 during movement can be further reduced, and the smoothness of the movement of the plate 195 can be improved.

[0034] Alternatively, the base component 112 may be a thicker plate 195 or a component of a frame structure.

[0035] Optionally, the feeding support 113 is a tubular structure, such as a stainless steel pipe. The tubular structure is generally inverted U-shaped or similar to an inverted U-shape, and both ends of the tubular structure are installed to the base member 112.

[0036] Continue reading Figure 9 In some further embodiments, the feeding device 110 also includes a base 114 and a height adjustment member 115. The base 114 is located below the base member 112. The height adjustment member 115 is connected between the base member 112 and the base 114. For different molding die heights, the height of the base member 112 is adjusted by the height adjustment member 115 to match the height of the molding die. Here, the molding die generally refers to the lower die 102.

[0037] See also Figure 9Furthermore, the height adjustment component 115 includes a vertical transmission rod 116, a horizontal transmission rod 117, and a lifting adjustment member 118. One of the vertical transmission rod 116 and the horizontal transmission rod 117 is provided with or connected to a worm gear. The other of the vertical transmission rod 116 and the horizontal transmission rod 117 is provided with or connected to a worm. The worm gear and the worm engage for transmission. That is, the vertical transmission rod 116 and the horizontal transmission rod 117 achieve vertical reversing transmission through a worm gear transmission structure. The lifting adjustment member 118 is connected to the horizontal transmission rod 117 so that it can be operated to drive the horizontal transmission rod 117 to rotate. The upper end of the vertical transmission rod 116 is connected to the base component 112. When the horizontal transmission rod 117 is driven to rotate by the lifting adjustment member 118, it can drive the vertical transmission rod 116 to move upward or downward, thereby adjusting the height of the base component 112.

[0038] Optionally, the lifting adjustment component 118 is a handwheel. In other embodiments, the lifting adjustment component 118 may be replaced by a motor.

[0039] Alternatively, the height position adjustment member 115 can also adopt other structural forms, as long as it can adjust the height of the base member 112 and lock the base member 112 at the corresponding height.

[0040] See also Figure 9 In some embodiments, the side positioning assembly 119 includes a side fixed positioning member 121, a side movable positioning member 122, and a side drive member 123. The side fixed positioning member 121 and the side movable positioning member 122 are located at both ends of the loading and bearing assembly 111 along the left-right direction Dlr. The side drive member 123 is connected to the side movable positioning member 122 and is used to drive the side movable positioning member 122 to move between a first positioning position and a first clearance position along the left-right direction Dlr. The side movable positioning member 122 located at the first positioning position is used to position the plate 195 together with the side fixed positioning member 121 along the left-right direction Dlr. The side movable positioning member 122 located at the first clearance position is used to allow the plate 195 to move between the side movable positioning member 122 and the side fixed positioning member 121. Here, the side fixed positioning member 121 serves as the positioning reference, and the side movable positioning member 122 is driven by the side driving member 123 to move along the left and right direction Dlr. When the side movable positioning member 122 pushes the plate 195 along the left and right direction Dlr to the position where it abuts against the side fixed positioning member 121, the positioning of the plate 195 along the left and right direction Dlr is achieved.

[0041] Optionally, both the side fixed positioning member 121 and the side movable positioning member 122 are constructed as rollers. The rollers are rotatable about an axis parallel to the vertical direction Dve. This reduces wear on the plate 195 and the resistance experienced by the plate 195 as it moves toward the discharge side 104 in the front-to-back direction Dfb.

[0042] See also Figure 9 Furthermore, a front-to-back position adjustment component 124 is provided between the side positioning component 119 and the feeding and bearing component 111. The front-to-back position adjustment component 124 is operated to adjust the position of the side positioning component 119 along the front-to-back direction Dfb. When the dimensions of the forming die along the front-to-back direction Dfb are different, the position of the side positioning component 119 along the front-to-back direction Dfb can be adjusted by operating the front-to-back position adjustment component 124 to improve adaptability and compatibility.

[0043] Optionally, the front-rear position adjustment assembly 124 includes a front-rear adjustment seat 125, a front-rear movable member 126, and a front-rear locking connector. The front-rear adjustment seat 125 is connected to the base member 112. The front-rear movable member 126 is slidably connected to the front-rear adjustment seat 125 in the front-rear direction Dfb. The front-rear movable member 126 is connected to the side positioning assembly 119. The front-rear locking connector is disposed between the front-rear adjustment seat 125 and the front-rear movable member 126. The front-rear locking connector is adapted to be operated to lock the front-rear movable member 126 and the front-rear adjustment seat 125, and to unlock the front-rear movable member 126 and the front-rear adjustment seat 125.

[0044] Specifically, the front and rear adjusting seat 125 has a T-shaped groove extending in the front-rear direction Dfb. The front and rear locking connector includes a bolt with an overall T-shaped shape and a nut that matches the bolt. The front and rear movable member 126 has a through hole for the bolt to pass through. The head of the bolt is slidably fitted into the T-shaped groove. The nut is screwed to the bolt on the outside of the front and rear movable member 126. Tightening the nut locks the position of the side positioning component 119 in the front-rear direction Dfb; loosening the nut allows the side positioning component 119 to move in the front-rear direction Dfb.

[0045] See also Figure 9 Furthermore, the side positioning assembly 119 also includes a left-right position adjustment member 128. The side movable positioning member 122 and the side drive member 123 are connected to the loading and bearing assembly 111 via the left-right position adjustment member 128. The left-right position adjustment member 128 is operated to adjust the position of the side movable positioning member 122 along the left-right direction Dlr. By providing the left-right position adjustment member 128, it is convenient to adjust the position of the side movable positioning member 122 and the side drive member 123 relative to the side fixed positioning member 121 along the left-right direction Dlr as needed to accommodate plates 195 of different widths.

[0046] Optionally, the left and right position adjustment component 128 includes a left and right adjustment seat 129, a left and right adjustment slider, and a left and right adjustment screw 132. The left and right adjustment seat 129 is connected to the feeding and bearing assembly 111, specifically to the aforementioned base component 112. The left and right adjustment slider is slidably connected to the left and right adjustment seat 129 along the left and right direction Dlr. The left and right adjustment screw 132 is rotatably connected to the left and right adjustment slider and the left and right adjustment seat 129 about an axis parallel to the left and right direction Dlr. The left and right adjustment screw 132 is threaded to the left and right adjustment slider or indirectly connected to the left and right adjustment slider through a nut. When the left and right adjustment screw 132 is operated to rotate, the left and right adjustment slider can be moved along the left and right direction Dlr, thereby driving the side movable positioning component 122 and the side driving component 123 to change position along the left and right direction Dlr; when the left and right adjustment screw 132 stops rotating, the left and right adjustment slider can be locked in a certain position, thereby fixing the side movable positioning component 122 and the side driving component 123 in a certain position.

[0047] Optionally, to facilitate the operation of the left and right adjustment screw 132, an adjustment handwheel 133 can be provided at the end of the left and right adjustment screw 132.

[0048] Optionally, the aforementioned side drive component 123 is a cylinder.

[0049] See also Figure 9 In some embodiments, the feeding assembly 134 includes a feeding member 135a and a multi-stroke drive member 136. The feeding member 135a protrudes at least partially from the upper surface of the feeding support assembly 111. The multi-stroke drive member 136 is connected to the feeding member 135a and is used to drive the feeding member 135a to move in multiple strokes along the front-rear direction Dfb toward the discharge side 104. By driving the feeding member 135a to move in the front-rear direction Dfb by the multi-stroke drive member 136, the plate 195 can be fed while moving toward the discharge side 104. Since the multi-stroke drive member 136 can drive the feeding member 135a to move in multiple strokes in stages, the plate 195 can be fed multiple times or in steps, thereby adapting to the cycle time of the pressing device 100 for multiple pressing processes.

[0050] Optionally, the pusher 135a includes a pusher plate. The multi-stroke drive component 136 includes a plurality of pusher cylinders 137 connected in sequence. Each pusher cylinder 137 is used to achieve a single stroke of propulsion. The plurality of pusher cylinders 137 are combined to achieve the propulsion purpose of multiple strokes.

[0051] In the illustrated example, there are five pusher cylinders 137. The cylinder body of the first pusher cylinder 137 is fixed to the base member 112. The cylinder body of the second pusher cylinder 137 is connected to the telescopic rod of the first pusher cylinder 137. The cylinder body of the third pusher cylinder 137 is connected to the telescopic rod of the second pusher cylinder 137. The telescopic rod of the third pusher cylinder 137 is connected to a pusher frame 135b. A pusher cylinder 137 is provided at each end of the pusher frame 135b. The telescopic rod of the pusher cylinder 137 located on the pusher frame 135b is connected to the pusher plate. During pushing, the first pusher cylinder 137, the second pusher cylinder 137, and the two pusher cylinders 137 located on the pusher frame 135b operate sequentially. During resetting, the two pusher cylinders 137, the second pusher cylinder 137, and the first pusher cylinder 137 located on the pusher frame 135b reset sequentially.

[0052] In other examples, the multi-stroke drive component 136 is a stepper motor. A lead screw and nut structure is provided between the stepper motor and the pusher component 135a. The stepper motor is connected to the lead screw. The lead screw is connected to the nut. The nut is directly or indirectly connected to the pusher component 135a. When the stepper motor is working, the stepper motor steps according to the input signal to realize the sequential pushing of the plate 195.

[0053] See Figure 11 In some embodiments, the rear positioning assembly 154 includes a rear positioning member 155 and a rear positioning drive member 156. The rear positioning drive member 156 is connected to the rear positioning member 155 and is used to drive the rear positioning member 155 to be movable in a second positioning position and a second clearance position along the vertical direction Dve of the forming device 100. The rear positioning member 155 in the second positioning position protrudes from the upper surface of the discharge bearing assembly 151 and is used to prevent the sheet 195 from moving in the front-rear direction Dfb. The rear positioning member 155 in the second clearance position does not protrude from the upper surface of the discharge bearing assembly 151 to allow the sheet 195 to move.

[0054] Continue reading Figure 11 Furthermore, the discharge support assembly 151 includes a discharge support plate 152 and a discharge connecting frame 153. The discharge support plate 152 is connected to the forming device 100. The discharge support plate 152 is arranged horizontally and extends in the front-rear direction Dfb. The upper surface of the discharge support plate 152 is used to support the plate 195. The plate 195 has a through hole 152a. The discharge connecting frame 153 is located below the discharge support plate 152 and is detachably connected to the discharge support plate 152 by fasteners such as bolts. The rear positioning drive member 156 is connected to the discharge connecting frame 153. The rear positioning member 155 is connected to the rear positioning drive member 156. The rear positioning member 155 is arranged corresponding to the through hole 152a so as to be movable through the through hole 152a of the support plate 195.

[0055] Optionally, the rear positioning member 155 is a cylindrical structure. The rear positioning drive member 156 is a rear positioning cylinder. The support plate 195 has an adjustment hole 152b. The adjustment hole 152b is suitable for inserting fasteners to connect the discharge connecting frame 153. The adjustment hole 152b is an elongated hole, and the length direction of the elongated hole is consistent with the front-rear direction Dfb. The adjustment hole 152b facilitates the adjustment of the position of the discharge connecting frame 153 along the front-rear direction Dfb or the adjustment of the distance between two adjacent discharge connecting frames 153 along the front-rear direction Dfb. Adaptively, the above-mentioned through hole is also an elongated hole extending along the front-rear direction Dfb.

[0056] Optionally, a ruler can be attached to the edge of the discharge bearing plate 152 for easy observation and adjustment of the distance.

[0057] See Figure 1 , Figures 6 to 8In some embodiments, the automatic sheet metal forming equipment further includes a centering and positioning device 160. The centering and positioning device 160 includes a positioning base plate 161, a bottom support member 162, a positioning reference member 166, a positioning movable member 167, and a centering drive member 168. The positioning base plate 161 is a flat plate inclined to the vertical direction Dve of the forming apparatus 100. The bottom support member 162 is connected to the lower end of the positioning base plate 161 and protrudes from the upper surface of the positioning base plate 161 to support the sheet metal located on the positioning base plate 161. The positioning reference member 166 and the positioning movable member 167 are spaced apart on the positioning base plate 161 along the horizontal direction Dho. The centering drive member 168 is connected to the positioning movable member 167 and drives the positioning movable member 167 to move along the horizontal direction Dho between a third positioning position and a third clearance position. The positioning movable member 167, located at the third positioning position, is used to position the sheet metal 195 together with the positioning reference member 166 along the horizontal direction Dho. The positioning movable member 167, located in the third clearance position, allows the plate 195 to move between the positioning movable member 167 and the positioning reference member 166. In use, the plate 195 is first placed on the positioning base plate 161, so that the plate 195 abuts against the positioning base plate 161 and is supported by the bottom support member 162, and the plate 195 is positioned between the positioning reference member 166 and the positioning movable member 167; then, the centering drive member 168 is activated, which drives the positioning movable member 167 to push the plate 195 along the horizontal direction Dho until the positioning movable member 167 moves to the third positioning position, so that the two ends of the plate 195 along the horizontal direction Dho abut against the positioning reference member 166 and the positioning movable member 167 respectively, thus completing the centering operation along the horizontal direction Dho. When placing the plate 195 onto the positioning base plate 161, it is not necessary to place the plate 195 directly onto the bottom support 162. For example, the plate 195 can be placed at a position spaced apart from the bottom support 162, and then the plate 195 can slide down to the bottom support 162 by its own weight. At the same time, by supporting the unleveled plate 195 with the positioning reference plate, the flatness of the unleveled plate 195 can be improved, thereby facilitating accurate gripping by the robot and loading into the loading device 110.

[0058] In the application state, the surface of the positioning substrate 161 that is used to contact the plate 195 is oriented towards the feeding device 110 and the forming device 100 in the front-to-back direction Dfb.

[0059] Optionally, a stop portion 166a is provided at the end of the positioning reference member 166 facing away from the positioning substrate 161 along a direction perpendicular to the positioning substrate 161. The stop portion 166a is used to prevent the plate member 195 located on the positioning substrate 161 from disengaging from the positioning substrate 161.

[0060] See Figure 6 and Figure 7Furthermore, the centering and positioning device 160 also includes a guide limiting member 169. The guide limiting member 169 is connected to the bottom support member 162. The guide limiting member 169 is opposite to and spaced apart from the positioning base plate 161. An upward-opening positioning groove 160a is formed between the guide limiting member 169, the bottom support member 162, and the positioning base plate 161. The positioning groove 160a is adapted to accommodate the plate 195. The opening size of the positioning groove 160a decreases from top to bottom. By providing the guide limiting member 169, the plate 195 located on the positioning base plate 161 can be limited in a direction perpendicular to the positioning base plate 161. On the other hand, with the opening of the positioning groove 160a properly set, the plate 195 can be shaped (e.g., flattened) at its lower edge to further improve the flatness of the plate 195.

[0061] Optionally, the opening of the positioning groove 160a is slightly larger than the thickness of the plate 195.

[0062] Optionally, the opening of the positioning groove 160a is less than 1.5 times the thickness of the plate 195.

[0063] Optionally, the guide limiting member 169 has a plate-like structure. The guide limiting member 169 includes a guide plate portion and a limiting plate portion. The guide plate portion and the limiting plate portion are arranged intersectingly. The guide plate portion is located above the limiting plate portion. The distance between the guide plate portion and the positioning substrate 161 decreases from top to bottom. The limiting plate portion is parallel to the positioning substrate 161. Along a direction parallel to the positioning substrate 161 and perpendicular to the horizontal direction Dho, the limiting plate portion protrudes from the surface of the bottom support member 162 used to support the plate 195. The surface of the bottom support member 162 used to support the plate 195 is perpendicular to the positioning substrate 161.

[0064] Optionally, the centering drive component 168 is a centering cylinder. The positioning movable component 167 is a plate-like structure.

[0065] Optionally, the number of positioning reference members 166 is at least two. The two positioning reference members 166 are spaced apart in a direction parallel to the positioning substrate 161 and perpendicular to the horizontal direction Dho. The number of positioning movable members 167 is at least two. The two positioning movable members 167 are spaced apart in a direction parallel to the positioning substrate 161 and perpendicular to the horizontal direction Dho.

[0066] In the illustrated example, the number of positioning actuators is the same as the number of positioning moving parts 167.

[0067] See Figure 8Furthermore, the bottom support 162 has a drainage hole 165. The drainage hole 165 extends through the bottom support 162 along an inclined direction Dob parallel to the positioning substrate 161 and perpendicular to the horizontal direction Dho. By providing the drainage hole 165, dust and other foreign objects attached to the plate 195 can be discharged after falling onto the bottom support 162, thereby preventing the accumulation of dust and other foreign objects on the bottom support 162 and reducing positioning accuracy.

[0068] Continue reading Figure 8 Furthermore, the bottom support 162 includes a bottom support strip 163 and a plurality of support blocks 164. The bottom support strip 163 extends horizontally in the direction of Dho. The plurality of support blocks 164 are connected between the bottom support strip 163 and the positioning base plate 161. At least a portion of the plurality of support blocks 164 are spaced apart horizontally in the direction of Dho to form a perforation 165 between adjacent support blocks 164. The perforation 165 here has the same function as the perforation 165 described above, so it will not be described again. The difference lies in the specific structure of the perforation 165. During installation, the bottom support strip 163 serves as the base for mounting the support blocks 164. Each support block 164 can be pre-installed on the bottom support strip 163 before being installed as a whole onto the positioning base plate 161. The support blocks 164 can be installed on the bottom support strip 163 using a detachable connection method such as bolt connection, thereby facilitating replacement operations. In application, the plate 195 is mainly supported by the support blocks 164.

[0069] See also Figure 8 Optionally, the support block 164 is made of a square block. At least a portion of the support block 164 has a chamfer 164a. The chamfer 164a is located at the upper end of the support block 164 and faces away from the positioning reference member 166. The chamfer 164a is provided to prevent the plate 195 from being obstructed by the corner of the support block 164 during the process of the positioning movable member 167 pushing the plate 195 against the positioning reference member 166 in the horizontal direction.

[0070] See Figure 1 , Figure 4 as well as Figure 5In some embodiments, the automated sheet metal forming equipment further includes a sheet metal conveyor line 170 and a transfer device 180. The sheet metal conveyor line 170 is used to convey the sheet metal parts 195 to be formed. The transfer device 180 includes a multi-axis robot 181 and a clamp 182. The multi-axis robot 181 is connected to the clamp 182 to move the clamp 182 to the sheet metal conveyor line 170, the centering and positioning device 160, and the loading device 110. The clamp 182 is used to grip and release the sheet metal. In operation, the multi-axis robot 181 moves the gripper 182 to the sheet metal conveyor line 170 and grips the sheet metal 195 to be pressed. Then, the multi-axis robot 181 moves the gripper 182 and the gripped sheet metal 195 to the centering and positioning device 160, releasing the sheet metal 195 to the centering and positioning device 160 for shaping and centering. Afterward, the multi-axis robot 181 moves the gripper 182 to grip the centered sheet metal 195 and transfers it to the loading device 110. By setting up the transfer device 180, the transfer of the sheet metal 195 can be completed automatically, reducing manual intervention, lowering labor intensity, and facilitating adaptation to automated production cycles. Because the centering and positioning device 160 can center the sheet metal 195 and improve its flatness, the flatness and positional accuracy of the sheet metal 195 transferred to the loading device 110 can be better guaranteed.

[0071] See Figure 5 Furthermore, the fixture 182 includes a mounting frame 183, a first material-grabbing member 184, and a plurality of second material-grabbing members 189. The plurality of second material-grabbing members 189 are arranged at intervals along a first direction D1 and a second direction D2 perpendicular to the first direction D1.

[0072] The first material-grabbing component 184 includes a material-grabbing cylinder 185, a first air guide rod 186, a first spring 187, and a first suction cup 188. The material-grabbing cylinder 185 is connected to the mounting bracket 183. The first air guide rod 186 is telescopically connected to the telescopic rod of the material-grabbing cylinder 185 along a third direction D3 perpendicular to the first direction D1 and the second direction D2. The first suction cup 188 is connected to the end of the first air guide rod 186. The first spring 187 is connected between the telescopic rod and the first suction cup 188.

[0073] The second material handling component 189 includes a second air guide rod 191, a second spring 192, and a second suction cup 193. The second air guide rod 191 is telescopically connected to the mounting bracket 183 along a third direction D3. The second suction cup 193 is connected to the end of the second air guide rod 191. The second spring 192 is connected between the mounting bracket 183 and the second suction cup 193.

[0074] The first air guide rod 186 and the second air guide bar are respectively used to connect to the air source through air passage pipes, solenoid valves, etc. The solenoid valve is used to control and change the air passage state.

[0075] In operation, the clamp 182, driven by the multi-axis robot 181, first moves towards the workpiece 195 to be gripped. Then, the clamp 182, driven by the multi-axis robot 181, presses against the workpiece 195. During this process, the first suction cups of the multiple second picking components 189 come into contact with the workpiece 195. Then, by activating the picking cylinder 185, the first suction cup 188 comes into contact with the workpiece 195. Finally, by controlling the airflow in the air passage, the first suction cup 188 and the second suction cup 193 generate suction force, thereby holding the workpiece 195 in place, thus achieving the gripping of the workpiece 195.

[0076] When the plate 195 being gripped is uneven, multiple second picking components 189 arranged at intervals along the first direction D1 and the second direction D2 perpendicular to the first direction D1 can adaptively grip different parts of the plate 195. The second suction cups 193 of the multiple second picking components 189 are positioned differently or not completely the same relative to the mounting frame 183 along the third direction D3.

[0077] Multiple second material-grabbing components 189 can be used to grip both flat and uneven plates 195. The first material-grabbing component 184 can position the gripped plate 195 in the first direction D1 and the second direction D2 to ensure that the plate 195 is accurately gripped and released.

[0078] Optionally, there are two sets of first picking members 184. The two sets of first picking members 184 are spaced apart along a first direction D1 of the mounting frame 183. A plurality of second picking members 189 are located between the two sets of first picking members 184.

[0079] Optionally, the first spring 187 and the second spring 192 are compression springs. The first spring 187 is sleeved on the outside of the first air guide rod 186. The first spring 187 is located between the mounting bracket 183 and the first suction cup 188. The first spring 187 is compressed when the first suction cup 188 approaches the mounting bracket 183. The second spring 192 is sleeved on the outside of the second air guide rod 191. The second spring 192 is located between the mounting bracket 183 and the second suction cup 193. The second spring 192 is compressed when the second suction cup 193 approaches the mounting bracket 183.

[0080] Optionally, the length of the first air guide rod 186 is less than that of the second air guide rod 191. The extension and retraction of the first spring 187 is less than that of the second spring 192. That is, the maximum retraction of the first air guide rod 186 relative to the mounting bracket 183 is less than the maximum retraction of the second air guide rod 191 relative to the mounting bracket 183. This ensures that after the first material-grabbing member 184 grips the plate 195, it can suppress the displacement or sway of the plate 195 along the perpendicular third direction D3, thus guaranteeing positioning accuracy compared to the technical solution that only sets the second material-grabbing member 189.

[0081] Alternatively, the multi-axis robot 181 can be an existing robot.

[0082] Continue reading Figure 5 Optionally, the mounting bracket 183 is detachably connected to the end effector of the multi-axis robot 181. The mounting bracket 183 has a connection portion 183a adapted for connection with the multi-axis robot 181. The connection portion 183a is, for example, a flange.

[0083] See Figure 4 and Figure 10 In some embodiments, to address the technical problem that the sheet metal 195 is difficult to enter the forming equipment due to factors such as sheet metal deformation and inconsistent mold height, the automatic sheet metal forming equipment of this utility model further includes an upper guide assembly 197. The upper guide assembly 197 is located on the feeding side 103 of the forming device 100. The upper guide assembly 197 is directly or indirectly connected to the upper mold 101 of the forming device 100. The upper guide assembly 197 includes an upper guide plate 197a. The lower surface of the upper guide plate 197a has a higher end and a lower end opposite in the front-rear direction Dfb. The higher end is positioned higher than the lower end in the vertical direction Dve. Along the front-rear direction Dfb, the distance between the higher end and the upper mold 101 is greater than the distance between the lower end and the upper mold 101. The lower end is flush with the lower surface of the upper mold 101. By setting the upper guide plate 197a, the plate 195 is easily guided so that the plate 195 can smoothly enter the space between the upper mold 101 and the lower mold 102.

[0084] Optionally, the upper guide assembly 197 further includes a mounting beam 197b and a guide leg 197c. The mounting beam 197b is directly or indirectly connected to the upper die 101. For example, the mounting beam 197b is connected to the press slide, which is connected to the upper die 101. One end of the guide leg 197c is connected to the mounting beam 197b, and the other end of the guide leg 197c is connected to the upper guide plate 197a.

[0085] Furthermore, the upper guide plate 197a includes an upper horizontal plate and an upper inclined plate. The upper horizontal plate is parallel to the horizontal plane. The upper inclined plate is inclined in the vertical direction Dve. The height of the lower surface of the upper inclined plate increases in the direction away from the upper horizontal plate. The upper horizontal plate is used to restrict the upward movement of the plate 195 in the vertical direction Dve. The upper inclined plate is used to guide the plate 195 towards the upper horizontal plate.

[0086] See Figure 4 and Figure 9 In some embodiments, the automatic sheet metal forming equipment further includes a lower guide assembly 198. The lower guide assembly 198 is mounted to the feeding device 110 and is arranged opposite to the upper guide assembly 197. The lower guide assembly 198 includes a lower guide plate 198a, an elastic element 198b, and a guide post. The lower guide plate 198a is connected to the upper end of the guide post. The guide post is slidably connected in the vertical direction (Dve) to a guide hole on the base member 112. The elastic element 198b is connected between the lower guide plate 198a and the base member 112. The elastic element 198b provides an elastic restoring force to move the lower guide plate 198a to a higher position. The upper surface of the lower guide plate 198a supports the sheet metal 195. The height of the upper surface of the lower guide plate 198a first increases and then decreases in the direction away from the discharge side 104. The lower guide plate 198a is arranged opposite to the upper guide plate 197a to guide the plate 195 during its spatial movement between the upper mold 101 and the lower mold 102. In short, the lower guide plate 198a is installed on the base component 112 in a flexible, floating manner. This not only meets the need to guide the plate 195 but also helps prevent rigid collisions between the upper guide plate 197a and the lower guide plate 198a when the upper mold 101 and lower mold 102 are closed, thus protecting both the upper guide plate 197a and the lower guide plate 198a.

[0087] Optionally, the lower guide plate 198a includes a lower horizontal plate and two lower inclined plates. The two lower inclined plates are disposed opposite each other at both ends of the lower horizontal plate. The lower horizontal plate is parallel to the horizontal plane. The lower inclined plates are inclined in the vertical direction Dve. The two lower inclined plates are inclined in opposite directions. The lower horizontal plate is used to support the plate 195. The lower inclined plates are used to guide the plate 195.

[0088] The control device is connected to the pressing device 100, the feeding device 110, the pushing component 134, the side positioning component 119, the discharge positioning device 150, the centering positioning device 160, and the transfer device 180, etc., so as to automatically control the transfer, positioning, and feeding operations of the sheet material to achieve the purpose of automated pressing.

[0089] Optionally, the control device can be an industrial computer, a host computer, or a controller including a PLC or a microcontroller.

[0090] In the illustrated example, the forming device 100, the feeding device 110, the sheet material conveying line 170, and the centering and positioning device 160 are installed on a base 194 such as a floor or ground. The sheet material conveying line 170 includes multiple rows of conveying rollers. Each row of conveying rollers is arranged along the left-right direction Dlr. The conveying rollers can rotate about an axis parallel to the front-back direction Dfb. The sheet material conveying line 170 can convey stacked sheets 195. The transfer device 180 destacking the stacked sheets 195 one by one and transferring them sequentially to the centering and positioning device 160 and the feeding device 110.

[0091] Optionally, a guide rail 196 extending in the front-to-back direction Dfb is provided on the bottom base 194. The forming device 100 and the sheet material conveying line 170 are adjustablely connected to the guide rail 196 in the front-to-back direction Dfb. The forming device 100 and the sheet material conveying line 170 are also provided with adjustable feet. When the adjustable feet are in contact with the bottom base 194, the movement of the forming device 100 and the sheet material conveying line 170 in the front-to-back direction Dfb can be restricted, thereby maintaining the adjusted position.

[0092] The automatic sheet metal forming equipment of this utility model can transform the manual positioning and transfer of flat sheet metal single-wave forming into continuous automatic single-wave forming, requiring only manual material unloading and reducing personnel. The use of mechanized operation reduces labor intensity and helps ensure consistent forming efficiency and quality during continuous long-term operation. The centering and positioning device 160 ensures that unleveled sheet metal can be flattened and positioned, thereby guaranteeing product centering accuracy. A robot places the first wave of sheet metal into the mold, and by controlling the press closing height, the unleveled sheet metal 195 can smoothly enter the mold, reducing the need for leveling operations in the previous process. Because the sheet metal is unleveled, a higher closing height is required when entering the press; however, subsequent pressing work does not require such a high closing height since the material has already entered the mold. An excessively high press closing height would affect the overall efficiency of the equipment. By automatically controlling the closing height of different waves of the press, the working time of a single press cycle is reduced, thereby improving the overall efficiency of the equipment.
