The demand for sofas is no longer just for basic sitting and lying functions, but more attention is paid to their comfort, aesthetics and functionality. Today's sofas include heavy-duty sofas, modular sofas and adjustable sofas. Compared with modular sofas and adjustable sofas, heavy-duty sofas are usually equipped with thick cushions and comfortable materials, and have a better sitting feel. Moreover, heavy-duty sofas usually have a higher sense of design and luxury, which can enhance the overall style of the interior. However, heavy-duty sofas are mostly made of solid wood or metal frames, so they are heavy in weight and usually require angle steel brackets to provide additional support to ensure the stability of the structure and reduce deformation or shaking of the sofa. Angle steel bracket is a metal component used to fix plates, usually made of L-shaped steel, easy to install, firm and reliable; when producing existing angle steel brackets, a punching machine is first used to punch the required connection holes on the surface of the angle steel, and these connection holes are used for the assembly and fixation of the angle steel brackets. Then, according to the design drawings and requirements, a punching machine is used to punch the angle steel to be bent, so as to prepare for subsequent bending and welding; then a bending machine is used to bend the angle steel at the punched part, so as to obtain the required L-shaped angle steel bracket, and finally welding and surface treatment are performed to improve the structural strength and corrosion resistance of the angle steel bracket; However, during the production process of the angle steel between the punching machine, the blanking machine and the bending machine, if the angle steel is subjected to uneven pressure or extrusion due to collision, it will cause deformation of the pre-treated part; especially for the blanking part of the angle steel, if deformation occurs, on the one hand, it will cause uneven force on the angle steel during the bending process, affecting the bending effect, and on the other hand, it will cause the welding surface to be uneven, which is easy to produce pores, cracks or weak welds during welding, thus affecting the welding quality; In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes a stamping equipment for producing a smart sofa bracket, which solves the above-mentioned technical problems.

On the one hand, the angle steel is subjected to uniform force during the bending process, thereby improving the bending effect of the angle steel.

[0018] As an embodiment of the present invention, a support plate 25 is provided on the side of the stamping plate 2 close to the punch 14; a flip plate 26 is provided on the side of the support plate 25 close to the observation port 112; the flip plate 26 and the support plate 25 are rotatably connected via a torsion spring; an electromagnetic plate No. 1 261 is embedded inside the flip plate 26; a side of the support plate 25 close to the flip plate 26 is fixedly connected with an electromagnetic plate No. 2 251 which is opposite to the electromagnetic plate No. 1 261; a conveying unit is installed on the upper end of the base 1.

[0019] As an embodiment of the present invention, the conveying unit includes an electric roller 17 ; connecting rods 27 are provided on both sides of the support plate 25 ; one end of the connecting rod 27 is fixedly connected to the support plate 25 , and the other end is connected to the top of the chassis 11 .

[0020] As an embodiment of the present invention, a push plate 28 is provided on the side of the punch 14 away from the observation port 112; the push plate 28 is fixedly connected to the side wall of the chassis 11 by an electric push rod 281; there are two push plates 28; the two push plates 28 are distributed on both sides of the punch 14; a discharge port 18 is opened at the upper end of the base 1; the discharge port 18 is located on the side of the punch 14 away from the electric push rod 281.

[0021] As an embodiment of the present invention, the push plate 28 is embedded with an electromagnetic plate 282 on one side away from the electric push rod 281; During operation, if the angle steel is subjected to uneven pressure or extrusion due to collision during the production process between the punching machine, blanking machine and bending machine, it will cause deformation of the pre-treated part; especially for the blanking part of the angle steel, if deformation occurs, on the one hand, it will cause uneven force on the angle steel during the bending process, affecting the bending effect, and on the other hand, it will cause the welding surface to be uneven, which is easy to produce pores, cracks or weak welds during welding, thus affecting the welding quality; In this regard, the present invention arranges the punch 14, the die 15 and the stamping plate 2 on the same base 1, so that when the angle steel is stamped on the stamping plate 2, the angle steel can complete the punching and the blanking of the bending part at one time, and then the angle steel after the stamping is transported between the punch 14 and the die 15 for bending processing, so as to avoid the problem of deformation of the angle steel due to uneven pressure or extrusion caused by collision during the production process. On the one hand, the angle steel is subjected to uniform force during the bending process, thereby improving the bending effect of the angle steel. On the other hand, the flatness of the welding part of the angle steel strip after bending is ensured to improve the welding quality, thereby improving the production quality of the angle steel bracket, so that the practicality of the present invention is effectively improved; The user cuts the angle steel according to the design size requirements and obtains the required length, and then puts the cut angle steel into the chassis 11 from the feed port 111; since the angle steel is L-shaped, the vertical edge of the L-shaped angle steel is placed between the two stamping plates 2, so that the two stamping plates 2 clamp the vertical edge of the angle steel through the two driving belts 212 connected thereto, and the horizontal edge of the angle steel contacts the upper end surface of the stamping plate 2 with the stamping groove 24; then the servo motor 22 is controlled to operate, so that the servo motor 22 can drive the rotating roller 211 connected thereto to rotate, so that the rotating roller 211 can drive the driving belt 212 mounted on its surface to rotate around during the rotation; since the driving directions of the two driving motors 192 in the two stamping plates 2 are opposite, the winding directions of the two driving belts 212 are opposite, so that the two The driving belt 212 can synchronously push the angle steel to move in the direction away from the feed port 111; at this time, the user observes the position of the angle steel on the stamping plate 2 through the observation port 112 until the end of the angle steel away from the feed port 111 is aligned with the end of the stamping plate 2 away from the feed port 111, and then controls the servo motor 22 to stop, and then controls the hydraulic cylinder 121 to push the punch 12 down, so that the descending punch 12 contacts the horizontal edge of the angle steel, and because the stamping part of the punch 12 is directly opposite to the stamping hole 23 and the stamping groove 24 on the upper end face of the stamping plate 2, the punch 12 cooperates with the stamping hole 23 and the stamping groove 24 to punch out the horizontal edge of the angle steel, so that the triangular notch required for punching and bending is generated on the horizontal edge of the angle steel, and then controls the servo motor 22 to drive the stamped angle steel to move in the direction of the flip plate 26 through the driving belt 212; In the initial state, the flip plate 26 is perpendicular to the support plate 25 under the action of the torsion spring restoring force; when the driving belt 212 drives the angle steel to the flip plate 26, the horizontal edge of the angle steel contacts the upper end surface of the flip plate 26; since the upper end surface of the flip plate 26 is coated with a coating of PTFE material, the angle steel and the flip plate 26 are in sliding contact, and the flip plate 26 supports the angle steel through the vertical edge of the angle steel, and in order to improve the supporting effect of the flip plate 26 on the angle steel, by embedding a No. 1 electromagnetic sheet 261 inside the flip plate 26, when the angle steel and the flip plate 26 are in sliding contact, the No. 1 electromagnetic sheet 261 inside the flip rod is energized, so that the No. 1 electromagnetic sheet 261 generates a magnetic adsorption force on the angle steel, so that the angle steel can be supported. The first electromagnetic sheet 261 is adsorbed and closely attached to the flip plate 26, thereby improving the supporting effect of the flip plate 26 on the angle steel; when the angle steel completely passes over the driving belt 212, the second electromagnetic sheet 251 is energized, so that the second electromagnetic sheet 251 generates a magnetic pole opposite to the first electromagnetic sheet 261, so that the second electromagnetic sheet 251 generates a magnetic adsorption force on the first electromagnetic sheet 261; since the support plate 25 is connected to the top of the chassis 11 through the connecting rod 27, the support plate 25 will not rotate, so that the support plate 25 is adsorbed by the adsorption force between the second electromagnetic sheet 251 and the first electromagnetic sheet 261, thereby adsorbing the flip plate 26 and rotating it in the direction close to the support plate 25, so that the flip plate 26 drives the angle steel downward When the angle steel is flipped to an inclined state, the angle steel will slide downward along the flip plate 26 under the action of its own gravity, so that the lower end of the vertical side of the angle steel contacts the electric roller 17, and is blocked by the electric roller 17, so that the angle steel no longer slides down. As the flip plate 26 continues to rotate, the flip plate 26 pulls the angle steel to fit with the first electromagnetic sheet 261 through the adsorption force, so that the flip plate 26 drives the angle steel to rotate synchronously with it, so that the lower end of the vertical side of the angle steel contacts the electric roller 17, and the horizontal side of the angle steel contacts the flip plate 26 at the same time, until the flip plate 26 flips 90°, at which time the vertical side of the angle steel flips to the bottom, and the side with the punched holes and the triangular notch is in the vertical direction. At this time, the first electromagnetic sheet 261 and the second electromagnetic sheet 251 are controlled to be powered off. At this time, the flip plate 26 is reset under the action of the torsion spring restoring force. Since the flip plate 26 no longer adsorbs the angle steel through the first electromagnetic sheet 261, the angle steel is pushed by the flip plate 26 and slides away from the flip plate 26. Because the vertical edge of the angle steel is provided with a punch hole and a triangular notch at this time, the mass of the vertical edge is less than the mass of the horizontal edge, so that the center of gravity of the angle steel located on the electric roller 17 is lowered, so that when the flip plate 26 pushes the angle steel to slide along the electric roller 17, the angle steel will not be overturned by the flip plate 26; then the electric roller 17 is controlled to rotate so that the electric roller 17 can drive the angle steel to move in the direction close to the punch 14;Since the female die 15 is located in the mounting groove 151 in the initial state, the angle steel will not be blocked by the female die 15 when the electric roller 17 drives the angle steel to the top of the mounting groove 151, so that the angle steel can pass between the male die 14 and the female die 15 until the angle steel contacts the side of the chassis 11 away from the feed port 111. At this time, the triangular notch of the angle steel is located between the male die 14 and the female die 15, and the edge of the notch of the angle steel is aligned with the bending center line of the mold. In order to prevent the triangular notch of the angle steel from contacting the male die 14 during the bending process and to avoid the interference of the notch edge with the male die 14 during the bending process, the present invention uses the push plate 28 and the electric push rod 28 to prevent the triangular notch of the angle steel from contacting the male die 14 during the bending process. 1, the electric push rod 281 is extended, so that the electric push rod 281 pushes the push plate 28 close to the angle steel; the push plate 28 contacts the angle steel and pushes the angle steel to move away from the electric push rod 281; when the side of the push plate 28 away from the electric push rod 281 and the side of the punch 14 away from the electric push rod 281 are in the same plane, at this time, the angle steel drives its triangular notch to pass over the punch 14, the electric push rod 281 is controlled to stop extending, and at the same time, the hydraulic push rod 16 is controlled to push the punch 14 and the die 15 close to each other, so that the punch 14 and the die 15 clamp the angle steel; then the electric push rod 281 is controlled to retract, and then the hydraulic push rod 16 pushes the punch 14 and the die 15 to clamp the angle steel. The die 14 and the die 15 bend the angle steel; after the angle steel is bent, the hydraulic push rod 16 is controlled to pull the punch 14 and the die 15 away from each other until the bottom of the cavity of the die 15 is in the same plane as the base 1, and the electric push rod 281 is controlled again to push the bent angle steel to move toward the discharge port 18 through the push plate 28. At this time, the angle steel at the upper end of the die 15 is pushed and slides to contact with the base 1; since the angle steel is located on the die 15 after bending and is in a V shape, when the angle steel slides to the base 1 through the die 15, the angle steel will tilt and deflect to one side under the action of gravity. If the angle steel deflects and causes part of it to go beyond one side of the discharge port 18, If the protruding portion is large, it is easy to cause the push plate 28 to be unable to effectively push the angle steel into the discharge port 18. For this, the present invention sets an electromagnetic plate 282 so that the push plate 28 controls the electromagnetic plate 282 to be energized during the process of pushing the angle steel to move, so that the push plate 28 adsorbs the angle steel through the electromagnetic plate 282, so that the angle steel and the electromagnetic plate 282 are in close contact, and then after the angle steel goes out of the die 15, the adsorbed angle steel will not deflect until the push plate 28 pushes the angle steel to the discharge port 18, and controls the electromagnetic plate 282 to be deenergized. At this time, the angle steel falls into the discharge port 18 under the action of its own gravity, so that the user can collect the bent angle steel conveniently. ;

[0022] As an embodiment of the present invention, the lower end surface of the punching groove 24 is configured as an inclined surface; the lower end surface of the punching groove 24 is rotatably connected with a ball 241 .

[0023] As an embodiment of the present invention, a strip groove 19 is provided on the upper end surface of the base 1; a screw rod 191 is rotatably connected in the strip groove 19; the threads at both ends of the screw rod 191 are oppositely arranged; the stamping plate 2 is connected to the screw rod 191 by spiral transmission; a drive motor 192 is fixedly installed on one side of the chassis 11; the drive motor 192 is used to drive the screw rod 191 to rotate.

[0024] As an embodiment of the present invention, the surface of the screw rod 191 is sleeved with a bellows 193; the end of the connecting rod 27 away from the support plate 25 is slidably connected to the top of the chassis 11; the support plate 25 is fixedly connected to the stamping plate 2; During operation, after the punch 12 cooperates with the punching hole 23 and the punching groove 24 to punch the horizontal edge of the angle steel to obtain the required punching holes and triangular notches required for bending, the punched metal waste will fall into the punching hole 23 and the punching groove 24. Since the punching hole 23 is connected to the discharge groove 13 below the punching plate 2, the metal waste that falls into the punching hole 23 will fall into the discharge groove 13. If the surface friction of the metal waste is large, it is easy to cause the waste that falls into the punching groove 24 to be difficult to fall into the discharge groove 13, so that the user needs to clean it manually, which increases the punching time of the entire production line and reduces the production efficiency of the present invention. For this, the lower end face of the punching groove 24 is set to be an inclined surface, and the lower end inclined surface of the punching groove 24 rotates A ball 241 is connected; after the waste material falls into the punching groove 24, the triangular waste material will contact the ball 241, so that the triangular waste material and the bottom of the punching groove 24 are in point contact due to the action of the ball 241, which greatly reduces the friction between the triangular waste material and the bottom of the punching groove 24, and because the bottom of the punching groove 24 is an inclined slope, the triangular waste material falling on the ball 241 is in an inclined state, so that the inclined triangular waste material rolls down from the side of the punching groove 24 away from the angle steel under the action of its own gravity, so that the triangular waste material can fall into the discharge groove 13 through the punching groove 24, thereby eliminating the need for manual cleaning by the user, reducing the time for producing and punching the angle steel, and improving the production efficiency of the present invention; Since the thickness of the angle steel required for sofas of different weights is also different, the thicker the angle steel, the stronger the supporting effect. Therefore, the heavier the sofa, the thicker the angle steel used. Therefore, in order to be able to stamp angle steels of different thicknesses; the present invention sets a screw rod 191, the threads at both ends of the screw rod 191 are set oppositely, and the two stamping plates 2 are spirally connected to the two ends of the screw rod 191. Therefore, when the driving motor 192 drives the screw rod 191 to rotate, when it is necessary to stamp the thicker angle steel, it is necessary to control the driving motor 192 to drive the two stamping plates 2 through the screw rod 191. The stamping plates 2 move in a direction away from each other, so that the distance between the two stamping plates 2 increases, so as to ensure that the two driving belts 212 just clamp the thicker angle steel, so that the driving belt 212 can drive the thicker angle steel to move along the stamping plate 2 in a direction away from the feed port 111, thereby realizing the present invention to stamp angle steels of different thicknesses, so that the practicality of the present invention is further improved; by setting the end of the connecting rod 27 away from the support plate 25 and slidingly connected to the top of the chassis 11, and the support plate 25 is fixedly connected to the stamping plate 2; so that the stamping plates 2 are mutually During the process of moving away, the stamping plate 2 will drive the support plate 25 to move away from the observation port 112, and the connecting rod 27 is slidably connected to the top of the chassis 11, so as to facilitate the stamping plate 2 to drive the flip plate 26 to move through the support plate 25; so that the flip plate 26 stretched to a horizontal state by the torsion spring will not block the vertical edge of the thicker angle steel, so as to ensure that the support plate 25 can effectively support and flip the angle steel through the flip plate 26, thereby improving the practicality of the present invention; when the driving belt 212 drives the stamped angle steel to move away from the feed port 111 When moving, the angle steel and the stamping plate 2 are in sliding contact, so that the burrs on the lower end surface of the angle steel caused by stamping will fall off due to the friction of the stamping plate 2. In the process of the angle steel passing over the strip groove 19, the burrs that fall off the angle steel fall into the strip groove 19. The setting of the bellows 193 is to prevent the burrs that fall into the strip groove 19 from clogging the threads on the surface of the screw 191, thereby avoiding the burrs blocking the normal transmission of the screw 191 and the stamping plate 2, thereby ensuring the driving effect of the screw 191 on the stamping plate 2, so that the actual application effect of the present invention is further improved.
