Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal processing, and in particular relates to a flattening device for flattening sheet metal parts. Background Art

[0002] In sheet metal processing, flattening refers to the process of transitioning a workpiece with a certain shape to a flat surface.

[0003] Existing sheet metal flattening equipment can usually only perform simple flattening operations on workpieces, such as setting the flattening part horizontally. However, for some workpieces with special structures, such as Figure 1 and Figure 2 As shown, it includes a workpiece body 10 and an internal reinforcement member 20. The workpiece body 10 extends in a straight line, has a V-shaped cross section, and has two side panels 11 intersecting into a V shape. The top edges of the two side panels 11 are formed with inner flanges 12 that fit with the inner walls of the side panels. The two ends of the inner flanges 12 are flush with the two ends of the workpiece body 10; the reinforcement member 20 strengthens the workpiece body 10, and is slidably inserted into the interior of the workpiece body 10, and the two long sides of the reinforcement member 20 are respectively fitted with the bottom surfaces of the inner flanges 12 of the two side panels 11. The length of the reinforcement member 20 is less than the length of the workpiece body 10, so at least one of the two ends of the reinforcement member 20 is located on the inner side of the same end of the inner flange 12, as shown in FIG. Figure 2 The part within the dotted box b is the flattened part of the workpiece body.

[0004] Since the flattening part is located on the inclined side panel of the workpiece body, that is, the flattening part is tilted, the existing flattening equipment cannot perform the flattening operation on such workpieces, and can only be flattened manually, which is inefficient and difficult to ensure the flattening quality.

[0062] In some embodiments of the present application, a flattening device is provided for flattening and shaping a flattened portion of a workpiece 1 .

[0063] The structure of workpiece 1 is as follows Figure 1 and Figure 2 As shown, it includes a workpiece body 10 and an internal reinforcement 20. The workpiece body 10 extends in a straight line and has a V-shaped cross section. It has two side panels 11 that intersect in a V shape. The top edges of the two side panels 11 are formed with inner flanges 12 that fit into the inner walls of the side panels 11. The two ends of the inner flange 12 are flush with the two ends of the workpiece body 10.

[0064] The reinforcement 20 strengthens the workpiece body 10. When installed, the reinforcement 20 is slidably inserted into the interior of the workpiece body 10, and the two long sides of the reinforcement 20 are respectively in contact with the bottom surfaces of the inner flanges 12 on the two side plates 11. The length of the reinforcement 20 is less than the length of the workpiece body 10, so that at least one of the two ends of the reinforcement 20 is located on the inner side of the same end of the inner flange 12, so that Figure 2 Taking the part in the dotted box b as an example, the left end of the reinforcement 20 is located on the inner side of the left end of the inner flange 12, and the flattened part is the part where the left end of the inner flange 12 exceeds the left end of the reinforcement 20, that is, part b; similarly, if both ends of the reinforcement 20 are located on the inner side of the corresponding ends of the inner flange 12, that is, the left end of the reinforcement 20 is located on the inner side of the left end of the inner flange 12, and the right end of the reinforcement 20 is located on the inner side of the right end of the inner flange 12, the flattened part is the part where the left end of the inner flange 12 exceeds the left end of the reinforcement 20, and the part where the right end of the inner flange 12 exceeds the right end of the reinforcement 20.

[0065] Reference Figures 3 to 11 The flattening equipment includes a positioning and pressing device 100, which is used to position and press the workpiece 1 to be flattened. It includes a pressing upper mold 110, a positioning lower mold 120 and a positioning and pressing power component 130 that drives the pressing upper mold 110 to rise and fall.

[0066] The flattening device includes a flattening device 200, which is used to flatten the part of the workpiece 1 (i.e. Figure 2 and Figure 9 The flattening of part b) includes a flattening upper die 210 (also called a flattening punch), a flattening lower die 220 and a flattening power component 230 that drives the flattening upper die 210 to rise and fall.

[0067] The flattening device further includes a control unit, which is used to control at least the working states of the positioning and pressing power component 130 and the flattening power component 230 .

[0068] The flattening device includes a body frame 300, which includes a workbench 310. The flattening device 200 and the positioning and pressing device 100 are arranged on the workbench 310, which is convenient for operation and realizes an integrated design, making the flattening device a whole, which is conducive to the rational use of space. The body frame 300 plays a certain safety protection role, and the control unit can be arranged in the space below the workbench 310 on the body frame 300.

[0069] In some embodiments of the present application, Figure 3 、 Figure 4 、 Figure 6 and Figure 8 As shown, the flattening power component 230 is a cylinder, which is arranged above the flattening body 240, the cylinder piston rod is vertically downward, the flattening upper mold 210 is connected to the output end of the cylinder piston rod, and the flattening upper mold 210 is located directly above the flattening lower mold 220. The flattening power component 230 drives the flattening upper mold 210 to move vertically downward, and after the flattening upper mold 210 contacts the part to be flattened of the workpiece 1, pressure is applied to the part to be flattened of the workpiece 1 through the flattening upper mold 210, so that the flattening upper mold 210 cooperates with the flattening lower mold 220 to realize the flattening forming of the flattened part of the workpiece 1, that is, the part to be flattened is formed into the flattened part on the workpiece 1.

[0070] The flattening upper die 210 includes a horizontal bottom surface 212 and a flattening plane 211. There are two flattening planes 211, which are located above the opposite sides of the horizontal bottom surface 212 and are symmetrically arranged. The flattening planes 211 are inclined relative to the horizontal bottom surface 212; the flattening lower die 220 includes a recessed accommodating portion 221 adapted to the outer contour of the workpiece 1, and a positioning plane 222 cooperating with the flattening plane 211. The recessed accommodating portion 221 is V-shaped, wide at the top and narrow at the bottom, and the opening is facing upward. The two opposite inner side surfaces of the recessed accommodating portion 221 correspond one-to-one to the two flattening planes 211, and the inclination direction and angle are consistent. The two opposite inner side surfaces of the recessed accommodating portion 221 constitute the positioning plane 222.

[0071] The inclined flattening plane 211 cooperates with the inclined positioning plane 222 to achieve flattening of the inclined flattening part.

[0072] When shooting normal, Figure 1 and Figure 2The workpiece 1 shown is supported in the recessed accommodating portion 221 of the flattening lower die 220. The outer contour of the workpiece 1 at the flattening portion is in contact with the positioning plane 222 of the flattening lower die 220. The portion to be flattened faces upward. The flattening upper die 210 moves vertically downward under the drive of the flattening power component 230 until the flattening plane 211 of the flattening upper die 210 contacts the portion to be flattened of the workpiece 1. The flattening upper die 210 continues to move downward, applying pressure to the portion to be flattened, squeezing the portion to be flattened between the flattening plane 211 of the flattening upper die 210 and the positioning plane 222 of the flattening lower die 220, gradually achieving flattening. After flattening, the portion to be flattened forms a flattened portion.

[0073] The flattening lower die 220 not only cooperates with the flattening upper die 210 to realize the flattening processing, but its recessed accommodating portion 221 can also play a role in positioning and supporting the workpiece 1, thereby helping to improve the processing quality of the workpiece 1; the above-mentioned flattening equipment can realize the automatic flattening of the inclined flattening parts on the workpiece 1, thereby improving the flattening quality and efficiency of such workpieces 1.

[0074] Correspondingly, the positioning plane 222 is the inner side surface of the recessed receiving portion 221, which is an inclined surface adapted to the flattening plane 211. The inclined flattening plane 211 cooperates with the inclined positioning plane 222 to achieve flattening of the inclined flattening portion.

[0075] like Figure 8 and Figure 9 As shown, the end of the workpiece 1 is placed in the recessed receiving portion 221 of the flattening lower die 220, the outer wall of the workpiece body 10 is fitted with the recessed receiving portion 221, and the inclined flattening plane 211 cooperates with the inclined positioning plane 222 to achieve flattening of the inclined flattening portion.

[0076] In some embodiments of the present application, Figure 7 and Figure 9 As shown, the flattening plane 211 and the horizontal bottom surface 212 are connected by a downward convex arc surface 213 to avoid damage to the workpiece 1 caused by the sharp connection.

[0077] An escape groove 223 is formed at the bottom tip of the recessed accommodating portion 221 to play an escape role and provide a certain escape buffer space for the workpiece 1 to move downward under the pressure of the flattening upper mold 210.

[0078] For Figure 1 and Figure 2In the straight, long workpiece 1 shown, the reinforcement 20 extends along the extension direction of the workpiece body 10, and the two side edges of the reinforcement 20 are respectively fitted with the bottom surfaces of the inner flanges 12 on the two side plates 11; the length of the reinforcement 20 is smaller than the length of the workpiece body 10, and the two ends of the reinforcement 20 are respectively located between the two ends of the inner flange 12, and both ends of the inner flange 12 need to be flattened, that is, at this time the workpiece 1 has two flattened parts at both ends, and the reinforcement 20 is located between the flattened parts at both ends.

[0079] If the lengths of the flattened parts at both ends need to be equal, the reinforcement 20 needs to be aligned with the workpiece body 10, that is, the distance between one end of the reinforcement 20 and the corresponding end of the workpiece body 10 needs to be equal to the distance between the other end of the reinforcement 20 and the corresponding end of the workpiece body 10. Therefore, before flattening, the reinforcement 20 needs to be aligned with the workpiece body 10.

[0080] In order to achieve automatic centering adjustment of the reinforcement 20 relative to the workpiece body 10, in some embodiments of the present application, the leveling device also includes a centering mechanism 400, which is used to drive the reinforcement 20 to slide relative to the inner flange 12 to a position aligned with the workpiece body 10 before leveling.

[0081] Specifically, before flattening, when the reinforcement 20 is placed into the workpiece body 10, it can be inserted from one end of the workpiece body 10 into the workpiece body 10 in the form of insertion until the reinforcement 20 is completely located in the workpiece body 10 and both ends are at a certain distance from the two ends of the workpiece body 10.

[0082] Then, the workpiece 1 is placed on the leveling device and put into position.

[0083] Before flattening, the centering mechanism 400 is operated to slide the reinforcement member 20 relative to the inner flange 12 to a position aligned with the workpiece body 10 .

[0084] In some embodiments of the present application, Figure 4 and Figure 11 As shown, the centering mechanism 400 is located outside the end of the workpiece 1, and includes a centering power component 410 and a centering pushing component 420 connected to the output end of the centering power component 410. The centering power component 410 is used to drive the centering pushing component 420 to move telescopically along the extension direction of the workpiece body 10. When the centering pushing component 420 is extended, it pushes the reinforcement 20 relative to the inner flange 12 to a position aligned with the workpiece body 10. After centering, the centering power component 410 drives the centering pushing component 420 to return to its position.

[0085] In some embodiments of the present application, a centering mechanism 400 is provided on each outer side of the two ends of the workpiece 1, and the centering pushing components 420 of the two sets of centering mechanisms 400 extend synchronously to push the reinforcement 20 relative to the inner flange 12 to a position aligned with the workpiece body 10.

[0086] That is, the two sets of centering mechanisms 400 extend synchronously from both ends of the reinforcement 20. Before centering, no matter which end of the reinforcement 20 is biased towards the workpiece body 10, there is a corresponding centering mechanism 400 to push it to slide to the centering position, thereby improving the efficiency and reliability of centering adjustment.

[0087] In some embodiments of the present application, the centering mechanism 400 further includes a guide component 430, such as Figure 5 As shown, the guide component 430 is fixedly arranged and has a guide channel 431 adapted to the cross-sectional profile of the centering pushing component 420 , and the centering pushing component 420 passes through the guide channel 431 .

[0088] The guide component 430 can support and guide the centering pushing component 420, thereby preventing the centering pushing component 420 of the cantilever structure from being completely deformed under its own weight.

[0089] The guide member 430 may be a block-shaped structure or a sheet-shaped structure, and may be fixed on the workbench 310 or on the flattened lower mold 220 .

[0090] To enhance the structural strength of the centering push component 420, it includes a fixed portion 421 and a push portion 422. The push portion 422 is perpendicularly connected to the fixed portion 421, and the fixed portion 421 is fixedly connected to the output end of the centering power component 410. Because the push portion 422 extends into the workpiece body 10 and contacts the reinforcement member 20 to push it, the push portion 422 can be relatively small. The fixed portion 421 is larger to enhance the overall structural strength of the centering push component 420 and increase the contact area with the output end of the centering power component 410, thereby improving connection reliability.

[0091] For a horizontally placed workpiece 1 , the centering power component 410 drives the centering pushing component 420 to move horizontally, which can be a horizontally installed multi-axis cylinder set on the workbench 310 or the leveling body 240 .

[0092] For positioning and clamping mechanisms, such as Figure 10 As shown, the clamping upper mold 110 includes a clamping part 111 and a connecting part 112, and the clamping part 111 and the connecting part 112 are connected as a whole. The connecting part 112 is connected to the power output end of the positioning and clamping power component 130. The positioning and clamping power component 130 drives the clamping part 111 to rise and fall through the connecting part 112, so that the clamping upper mold 110 cooperates with the positioning lower mold 120 to achieve clamping of the workpiece 1.

[0093] The positioning lower die 120 of the positioning and clamping mechanism has a recessed positioning portion 121 adapted to the outer contour of the workpiece 1 . The recessed positioning portion 121 opens upward, and the workpiece 1 fits and is positioned in the recessed positioning portion 121 , so that the workpiece 1 can be reliably positioned.

[0094] In some embodiments of the present application, the positioning and pressing device 100 also includes a base 140, and the positioning lower mold 120 and the positioning and pressing power component 130 are fixed on the base 140. The positioning and pressing power component 130 pulls the pressing upper mold 110 downward to move downward, thereby pressing the workpiece 1.

[0095] The positioning and pressing device 100 has a compact and stable structure with a low center of gravity. By pulling down the upper die 110 to press the workpiece 1 , the upper die 110 moves smoothly and reliably, thereby further improving the positioning and pressing effect of the workpiece 1 .

[0096] like Figure 10 As shown, the positioning lower mold 120 and the positioning and clamping power component 130 are arranged side by side on the base 140. The positioning and clamping power component 130 is relatively high and adopts a multi-axis cylinder arranged upright and upward. The clamping upper mold 110 is in a horizontal L-shape, and its horizontal part is the connecting part 112, which is fixed to the output end of the multi-axis cylinder by screws. The vertical part of the clamping upper mold 110 is downward to form a clamping part 111, which is located directly above the positioning lower mold 120.

[0097] The multi-axis cylinder has a large contact area with the connecting portion 112, so that the downward pulling force transmitted to the pressing portion 111 is large and uniform, so that the pressing force of the pressing portion 111 on the workpiece 1 is as balanced as possible, making the pressing reliable.

[0098] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the flattening device further includes a supporting component 500 for auxiliary supporting the workpiece 1 .

[0099] The support member 500 may be a support column, the top of which has a support groove adapted to the outer contour of the workpiece 1, and the workpiece 1 is supported in the support groove. For a long workpiece 1, multiple support members 500 may be arranged at intervals along the length direction of the workpiece 1.

[0100] The supporting member 500 is also provided on the workbench 310 of the machine body frame 300 .

[0101] The positioning and pressing device 100 and the centering mechanism 400 can be arranged on the workbench 310 or on the flattening machine body 240 , and are respectively located on opposite sides of the flattening lower mold 220 .
