Description

Technical Field

[0001] This invention relates to the field of sheet metal bending technology, and more particularly to a pressing mold for reinforcing ribs of sheet metal bending parts. Background Technology

[0002] Sheet metal bending parts are widely used in various fields such as automobiles, aerospace, electronic equipment, and construction due to their good structural strength and machinability. To further enhance the rigidity of bending parts and prevent deformation, various reinforcing ribs are usually pressed into the sheet metal parts. This is an economical and effective method of structural strengthening.

[0003] Existing sheet metal reinforcing rib pressing processes typically include steps such as loading, positioning, pressing, and unloading. However, in current technical practice, especially for automated or semi-automated production lines, several significant technical bottlenecks still exist: In the material loading and positioning stages, traditional equipment often lacks efficient and flexible feeding mechanisms. Common practices include using rigid push rods or manual intervention for positioning, which makes it difficult to ensure that sheet metal materials (such as aluminum plates) are continuously and accurately fed to the predetermined position at the center of the mold. Aluminum plate surfaces are easily scratched, and ordinary metal drive wheels not only pose a risk of slippage but can also severely damage the workpiece surface, affecting product aesthetics and performance. Furthermore, how to automatically and seamlessly transport and accurately position the next workpiece after the previous one has been processed is a key challenge for achieving continuous production. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of efficient and flexible feeding mechanisms in traditional equipment. Common practices involve using rigid push rods or manual intervention for positioning, which makes it difficult to ensure the continuous and precise delivery of sheet metal materials (such as aluminum plates) to the predetermined position at the center of the mold. Aluminum plate surfaces are easily scratched, and ordinary metal drive wheels not only pose a risk of slippage but can also severely damage the workpiece surface, affecting product aesthetics and performance. Furthermore, this invention addresses the problem of how to automatically and seamlessly transport and accurately position the next workpiece after the previous one has been processed.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a pressing mold for reinforcing ribs of sheet metal bending parts, comprising: a base plate, a stacking plate, fixedly installed on one side of the base plate, and a limiting component provided on the top of the stacking plate; wherein, the limiting component comprises: a U-shaped frame, two sliding grooves, multiple limiting springs, and a long strip, the two sliding grooves being opened on the inner wall of opposite sides of the U-shaped frame, the long strip being slidably connected inside the two sliding grooves, the multiple limiting springs being fixedly installed on the upper surface of the long strip, the top ends of the multiple limiting springs being fixedly connected to the outer surface of the U-shaped frame, and a feeding component provided at the bottom of the long strip; wherein, the feeding component comprises: a vertical block, a motor, two friction wheels, and a belt, the motor being fixedly installed on one side of the vertical block, a pulley being fixedly installed on the output shaft of the motor, the belt being sleeved on the pulley, the bottom end of the belt being movably sleeved on one end of a rotating rod through the pulley, the rotating rod penetrating through the inner wall of the vertical block through a bearing, and the two friction wheels being fixedly installed on the outer surface of the rotating rod.

[0006] The technical effect of the above-mentioned further solution is as follows: Sheet metal material is piled on the upper surface of the stacking plate. At this time, the elastic force of the second limiting spring limits the long strip, which slides downward inside the groove. This causes the friction wheels on both sides of the vertical block to adhere to the upper surface of the sheet metal material. The motor is started by an external power source, and the motor drives the belt through the pulley. The bottom end of the belt drives the pulley, which in turn drives the second rotating rod to rotate. The second rotating rod passes through the interior of the vertical block via a bearing. The second rotating rod drives the friction wheels on the outer surface to rotate. The rotating friction wheels generate friction with the upper surface of the sheet metal material. The friction wheels are made of polyurethane, which provides excellent driving force, prevents slippage, and ensures smooth movement of the aluminum plate. While providing sufficient friction, it minimizes wear and scratches on the aluminum plate surface. When the aluminum plate moves to the surface opposite the fixed block and the clamping block, the friction wheels stop rotating. Under the elastic force of the second limiting spring, the friction wheels always adhere to the top of the next aluminum plate, enabling continuous feeding.

[0007] As a preferred embodiment, the stack plate 121 is provided with a lifting mechanism or a separating plate to ensure that only the topmost aluminum plate contacts the friction wheel 127 at a time.

[0008] In a preferred embodiment, two side plates are fixedly installed on the top of the base plate. Two vertical grooves are formed on the inner wall of each of the two side plates on opposite sides. Rollers are rotatably connected inside the two vertical grooves. Limiting frames are fixedly installed on the side of each of the two side plates near the vertical grooves. Long rods are slidably connected inside the multiple limiting frames. Rectangular blocks are rotatably installed on the outer surface of the multiple long rods. Limiting springs are fixedly installed on the top of the multiple rectangular blocks. Connecting blocks are fixedly installed on the top of the multiple limiting springs. One side of the multiple connecting blocks is fixedly installed on the top of the two side plates.

[0009] The technical effect of adopting the above-mentioned further solution is that: when the aluminum plate is extruded, the aluminum plate will deform and its position around the perimeter will change accordingly. At this time, the side strip moves inside the hollow block. The hollow block rotates around the rectangular block through the round rod. The movable block rotates around the side strip through the rotating rod. The movable block can realize the angle movement, that is, the movable block can be angled to adapt to the movement of the aluminum plate around the perimeter during forming.

[0010] In a preferred embodiment, a round rod is rotatably connected to one side of each of the plurality of rectangular blocks, a hollow block is rotatably mounted on the outer surface of each of the plurality of round rods, a side strip is slidably connected inside each of the plurality of hollow blocks, and a rotating rod is rotatably connected inside each of the plurality of side strips.

[0011] The technical effect of adopting the above-mentioned further solution is that the hollow block can rotate around the rectangular block with the round rod as the center, the movable block can rotate in a semi-circle around the side strip with the rotating rod as the center, and the roller can roll inside the vertical groove, which can be used for the movement trajectory of the aluminum plate during forming.

[0012] In a preferred embodiment, each of the multiple rotating rods has a movable block rotatably mounted on its outer surface, each of the multiple movable blocks has an electric push rod fixedly mounted on one side, each of the multiple electric push rods has a clamping block fixedly mounted on its bottom end, and each of the multiple movable blocks has a fixing block fixedly mounted on one side.

[0013] The technical effect of adopting the above-mentioned further solution is as follows: the electric push rod is started by an external power source, and the electric push rod pushes the clamping block to move downward. At this time, the clamping block and the fixing block fix the aluminum plate. The aluminum plate is clamped on all sides, eliminating the need for manual feeding and positioning of the aluminum plate, which facilitates the forming operation. During extrusion forming, the deformation of the aluminum plate poses certain safety hazards to the surrounding area, which can effectively protect the workers.

[0014] In a preferred embodiment, two electric push rods are fixedly installed on the top of the base plate, and H-shaped strips are fixedly connected to the top of each of the two electric push rods. The two H-shaped strips are located at the bottom of multiple hollow blocks and movable blocks, and connecting strips are fixedly installed on the top of the base plate.

[0015] The technical effect of adopting the above-mentioned further solution is: by starting the electric push rod two, the H-shaped strip moves downward. At this time, the H-shaped strip separates from the bottom of the movable block and the hollow block. The purpose of setting the H-shaped strip is to support the movable block and the hollow block, and to prevent the hollow block from sticking to one side of the side plate when the aluminum plate is about to enter the upper surface of the fixed block, so that the aluminum plate cannot be fed to the upper surface of the fixed block.

[0016] In a preferred embodiment, two cylinders are fixedly installed at the bottom of the connecting strip, pressure blocks are fixedly installed at the bottom of the two cylinders, and a groove is fixedly installed at the top of the base plate.

[0017] The technical effect of adopting the above-mentioned further solution is that the cylinder is started by an external power source to push the pressure block downward, and the aluminum plate is squeezed into the interior of the groove for forming.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this embodiment of the invention, sheet metal material is stacked on the upper surface of the stacking plate. At this time, the elastic force of the limiting spring two limits the long strip, and the long strip slides downward inside the slide groove, so that the friction wheels on both sides of the vertical block are in contact with the upper surface of the sheet metal material. The motor is started by an external power source, and the motor drives the belt to move through the pulley. At this time, the bottom end of the belt drives the pulley to move, and the pulley drives the rotating rod two to rotate. The rotating rod two passes through the interior of the vertical block through the bearing. The rotating rod two drives the friction wheel on the outer surface to rotate. The friction wheel rotates and generates friction with the upper surface of the sheet metal material. The material used for the friction wheel is polyurethane, which can provide excellent driving force, prevent slippage, and ensure the smooth movement of the aluminum plate. While providing sufficient friction, it minimizes wear and scratches on the surface of the aluminum plate. When the aluminum plate moves to the surface opposite to the fixed block and the clamping block, the friction wheel stops rotating. Under the action of the elastic force of the limiting spring two, the friction wheel is always in contact with the top of the next aluminum plate, which can realize continuous feeding.

[0019] 2. In this embodiment of the invention, the aluminum plate is located directly below the pressure block and directly above the groove. The cylinder is activated by an external power source to push the pressure block downward, and the aluminum plate is squeezed into the interior of the groove for forming. During the extrusion of the aluminum plate, the aluminum plate will deform, and its position around its perimeter will change accordingly. At this time, the side strips move inside the hollow block. The hollow block rotates around the rectangular block via a round rod, and the movable block rotates around the side strip via a rotating rod. The movable block can achieve angular movement to adapt to the movement of the aluminum plate around its perimeter during forming. The aluminum plate is clamped around its perimeter, eliminating the need for manual feeding and positioning of the aluminum plate, which facilitates the forming operation. The deformation of the aluminum plate during extrusion forming poses a certain safety hazard to the surrounding area, which can effectively protect the workers.

[0020] 3. In this embodiment of the invention, the electric push rod one is started by an external power source. The electric push rod one pushes the clamping block to move downward. At this time, the clamping block and the fixed block fix the aluminum plate. After fixing, the electric push rod two is started to drive the H-shaped strip to move downward. At this time, the H-shaped strip separates from the bottom of the movable block and the hollow block. The purpose of setting the H-shaped strip is to support the movable block and the hollow block and prevent the hollow block from sticking to one side of the side plate when the aluminum plate is about to enter the upper surface of the fixed block, so that the aluminum plate cannot be fed to the upper surface of the fixed block.

[0021] 4. In this embodiment of the invention, the descent of the H-shaped bar can simultaneously release the bottom supports of all hollow blocks and movable blocks, allowing multiple clamping units to adjust their positions freely and synchronously to adapt to the deformation of the aluminum plate. That is, by raising or lowering a single H-shaped bar, the support for all surrounding clamping units can be simultaneously released or provided, enabling them to synchronously and coordinately adapt to the deformation of the aluminum plate during the pressing process. This avoids the tediousness of adjusting each unit individually, improves the stability and efficiency of the overall forming process, and produces a synergistic effect. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 8 This embodiment provides a technical solution: a pressing mold for reinforcing ribs of sheet metal bending parts, comprising: a base plate 101, a stacking plate 121, fixedly installed on one side of the base plate 101, and a limiting component provided on the top of the stacking plate 121; wherein, the limiting component includes: a U-shaped frame 122, two sliding grooves 123, multiple limiting springs 124, and a long strip 125, the two sliding grooves 123 are both opened on the inner wall of opposite sides of the U-shaped frame 122, the long strip 125 is slidably connected inside the two sliding grooves 123, and the multiple limiting springs 124 are fixedly installed on the upper surface of the long strip 125. The top of the second component 124 is fixedly connected to the outer surface of the U-shaped frame 122, and a feeding assembly is provided at the bottom of the long strip 125. The feeding assembly includes: a vertical block 126, a motor 128, a belt 129, a rotating rod 130, and two friction wheels 127. The motor 128 is fixedly installed on one side of the vertical block 126, and a pulley is fixedly installed on the output shaft of the motor 128. The belt 129 is sleeved on the pulley, and the bottom end of the belt 129 is movably sleeved on one end of the rotating rod 130 via the pulley. The rotating rod 130 passes through the inner wall of the vertical block 126 via a bearing. The two friction wheels 127... Fixedly installed on the outer surface of the rotating rod 130, sheet metal material is piled on the upper surface of the stacking plate 121. At this time, the elastic force of the limiting spring 124 limits the long strip 125, and the long strip 125 slides downward inside the slide groove 123, so that the friction wheels 127 on both sides of the vertical block 126 are in contact with the upper surface of the sheet metal material. The motor 128 is started by an external power source. The motor 128 drives the belt 129 to move through the pulley. At this time, the bottom end of the belt 129 drives the pulley to move, and the pulley drives the rotating rod 130 to rotate. The rotating rod 130 passes through the interior of the vertical block 126 through the bearing. The rotating rod 130 drives the friction wheel 127 on the outer surface to rotate. The friction wheel 127 rotates and generates friction with the upper surface of the sheet metal material. The friction wheel 127 is made of polyurethane, which can provide excellent driving force, prevent slippage, and ensure the smooth movement of the aluminum plate. While providing sufficient friction, it minimizes wear and scratches on the surface of the aluminum plate. When the aluminum plate moves to the surface opposite to the fixed block 115 and the clamping block 114, the friction wheel 127 stops rotating. Under the elastic force of the limit spring 124, the friction wheel 127 is always in contact with the top of the next aluminum plate, which can realize continuous feeding.

[0026] like Figures 1 to 8 As shown, in one embodiment, two side plates 102 are fixedly installed on the top of the base plate 101. Two vertical grooves 103 are formed on the inner walls of opposite sides of each side plate 102. Rollers 105 are rotatably connected inside each of the two vertical grooves 103. Limiting frames 104 are fixedly installed on the side of each side plate 102 near the vertical grooves 103. Long rods 106 are slidably connected inside each limiting frame 104. Rectangular blocks are rotatably installed on the outer surfaces of each long rod 106. Limiting springs 108 are fixedly installed on the top of each rectangular block. Each limiting spring 108 has a connecting block 107 fixedly installed on its top. One side of each connecting block 107 is fixedly installed on the top of the two side plates 102. When the aluminum plate is extruded, the aluminum plate will deform and its position will change accordingly. At this time, the side strip 110 moves inside the hollow block 109. The hollow block 109 rotates around the rectangular block through the round rod 1081. The movable block 112 rotates around the side strip 110 through the rotating rod 111. The movable block 112 can move within a certain angle through 106 to adapt to the movement of the aluminum plate around its perimeter during forming.

[0027] like Figures 1 to 8 As shown, in one embodiment, a circular rod 1081 is rotatably connected to one side of a plurality of rectangular blocks, and hollow blocks 109 are rotatably mounted on the outer surface of the plurality of circular rods 1081. Side strips 110 are slidably connected inside the plurality of hollow blocks 109, and rotating rods 111 are rotatably connected inside the plurality of side strips 110. The hollow blocks 109 can rotate around the rectangular blocks with the circular rods 1081 as the center. The movable block 112 rotates semi-circularly around the side strips 110 with the rotating rods 111 as the center. The rollers 105 roll inside the vertical grooves 103 and can be used for the movement trajectory of the aluminum plate during forming.

[0028] like Figures 1 to 8 As shown, in one embodiment, movable blocks 112 are rotatably mounted on the outer surfaces of multiple rotating rods 111. Electric push rods 113 are fixedly mounted on one side of each movable block 112. Clamping blocks 114 are fixedly mounted on the bottom ends of each electric push rod 113. Fixed blocks 115 are fixedly mounted on one side of each movable block 112. When the electric push rods 113 are started by an external power source, they push the clamping blocks 114 downward. At this time, the clamping blocks 114 and the fixed blocks 115 fix the aluminum plate. The aluminum plate is clamped around its perimeter, eliminating the need for manual feeding and positioning of the aluminum plate. This facilitates the forming operation. During extrusion forming, the deformation of the aluminum plate poses a certain safety hazard to the surrounding area, which can effectively protect the workers.

[0029] like Figures 1 to 8As shown, in one embodiment, two electric push rods 116 are fixedly installed on the top of the base plate 101. H-shaped strips 117 are fixedly connected to the top of each of the two electric push rods 116. The two H-shaped strips 117 are located at the bottom of the multiple hollow blocks 109 and the movable block 112. A connecting strip 120 is fixedly installed on the top of the base plate 101. By starting the electric push rods 116, the H-shaped strips 117 are driven to move downward. At this time, the H-shaped strips 117 are disengaged from the bottom of the movable block 112 and the hollow block 109. The purpose of setting the H-shaped strips 117 is to support the movable block 112 and the hollow block 109, and to prevent the hollow block 109 from sticking to one side of the side plate 102 when the aluminum plate is about to enter the upper surface of the fixed block 115, so that the aluminum plate cannot be fed to the upper surface of the fixed block 115.

[0030] A preferred embodiment is that the H-shaped strip 117 is horizontally arranged, with its two upper flanges extending into and supporting the area below the connection between the multiple hollow blocks 109 and the movable block 112, to provide support in the non-working state.

[0031] like Figures 1 to 8 As shown, in one embodiment, two cylinders 118 are fixedly installed at the bottom of the connecting strip 120, and pressure blocks 119 are fixedly installed at the bottom of the two cylinders 118. A groove 2 is fixedly installed at the top of the base plate 101. When the cylinders 118 are started by an external power source, they push the pressure blocks 119 downward, and the aluminum plate is squeezed into the interior of the groove 2 for forming.

[0032] Working principle: During use, sheet metal material is piled on the upper surface of the stacking plate 121. At this time, the elastic force of the limiting spring 124 limits the long strip 125, which slides downward inside the slide groove 123. This causes the friction wheels 127 on both sides of the vertical block 126 to adhere to the upper surface of the sheet metal material. The motor 128 is started by an external power source. The motor 128 drives the belt 129 to move through the pulley. At this time, the bottom end of the belt 129 drives the pulley to move, and the pulley drives the rotating rod 130 to rotate. The rotating rod 130 passes through the interior of the vertical block 126 through a bearing. The rotating rod 130 drives the rotation of the vertical block 126. The friction wheel 127 on the outer surface rotates, generating friction with the upper surface of the sheet metal material. The friction wheel 127 is made of polyurethane, which provides excellent driving force, prevents slippage, and ensures smooth movement of the aluminum plate. While providing sufficient friction, it minimizes wear and scratches on the surface of the aluminum plate. The aluminum plate moves on the upper surface of the stacking plate 121. After moving to the opposite surface of the fixing block 115 and the clamping block 114, the friction wheel 127 stops rotating. Under the elastic force of the limit spring 124, the friction wheel 127 is always in contact with the upper surface of the next aluminum plate, which can realize continuous feeding.

[0033] A preferred embodiment is that a guide plate or conveyor roller is provided on the base plate 101 between the stacking plate 121 and the fixing block 115. After being driven by the friction wheel 127, the aluminum plate moves along the guide structure to above the fixing block 115.

[0034] At this time, the electric push rod 113 is activated by the external power supply. The electric push rod 113 pushes the clamping block 114 to move downward. At this time, the clamping block 114 and the fixing block 115 fix the aluminum plate. After fixing, the electric push rod 116 is activated to drive the H-shaped strip 117 to move downward. At this time, the H-shaped strip 117 disengages from the bottom of the movable block 112 and the hollow block 109. The purpose of setting the H-shaped strip 117 is to support the movable block 112 and the hollow block 109, and to prevent the hollow block 109 from sticking to one side of the side plate 102 when the aluminum plate is about to enter the upper surface of the fixing block 115, so that the aluminum plate cannot be fed to the upper surface of the fixing block 115. At this time, the aluminum plate is located directly below the pressure block 119 and directly above the groove 2. The cylinder 118 is started by an external power source to push the pressure block 119 downward. The aluminum plate is squeezed into the interior of the groove 2 for forming. During the extrusion of the aluminum plate, the aluminum plate will deform, and its position around it will change accordingly. At this time, the side strip 110 moves inside the hollow block 109. The hollow block 109 rotates around the rectangular block via the round rod 1081. The movable block 112 rotates around the side strip 110 via the rotating rod 111. The movable block 112 can achieve angular movement to adapt to the movement of the aluminum plate around its perimeter during forming. The aluminum plate is clamped around its perimeter, eliminating the need for manual feeding and positioning of the aluminum plate, which facilitates the forming operation. The deformation of the aluminum plate during extrusion forming poses a certain safety hazard to the surrounding area, which can effectively protect the workers.
