It is generally widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industry, etc. Among them, galvanized steel sheet is usually made into auto parts by stamping in the automotive field. Stamping refers to a processing method in which a press and a mold are used to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. The purpose of stamping is to obtain parts of better quality, prevent the steel plate from rusting, and increase its service life.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Combination Figures 1 to 4 As shown, a galvanized steel sheet stamping forming device according to an embodiment of the present invention comprises a base 1, a mounting seat 2 is fixedly connected to the top of the base 1, a support plate 3 is fixedly connected to the top of the mounting seat 2, a platform is installed on the top of the support plate 3, a cylinder 4 is fixedly connected above the platform, a compressor is externally connected to the cylinder 4, and high-pressure gas is produced by the matched compressor. Under the push of the high-pressure gas, the cylinder 4 can be used normally, a piston rod 5 is telescopically connected to the bottom of the cylinder 4, a solenoid valve 6 is fixedly connected to the bottom end of the piston rod 5, a pressing piece 61 is fixedly connected to the rear of the solenoid valve 6, a punch 7 is fixedly connected to the middle of the bottom end of the solenoid valve 6, and recovery components are installed on both sides of the solenoid valve 6, and the recovery components are used to collect the formed galvanized steel sheet workpiece and stamping burrs to prevent the galvanized steel sheet workpiece from accumulating after discharge. The support plate 3 is in chaos. The inner wall of the support plate 3 is slidably connected with an extrusion seat 8. A pushing component is installed in the middle of the front of the extrusion seat 8. The pushing component includes an electric telescopic cylinder 84 installed on the side of the extrusion seat 8. The pushing component is used to remove the galvanized steel sheet workpiece stuck in the stamping and forming equipment due to extrusion, so as to facilitate the next use. The top of the mounting seat 2 is located in front of the support plate 3 and is fixedly connected with a stamping table 9. A through groove is provided in the stamping table 9 for limiting the galvanized steel sheet workpiece. A forming component is installed inside the stamping table 9. The forming component stamps the galvanized steel sheet through a downward movement. The galvanized steel sheet is pressed down into the interior of the stamping table 9. Under the constraint of the through groove, the two sides move closer to the middle. Under the action of the closing force, the galvanized steel sheet is extruded into a shape corresponding to the punch 7.

[0023] During work, after the galvanized steel sheet workpiece is stamped and formed, the galvanized steel sheet workpiece needs to be collected and processed after being discharged. In the premise scenario of stamping and forming in a small workshop, since the price of manipulator to take materials is expensive and the cost is high, most of the materials are taken manually. However, this method is relatively inefficient, and the galvanized steel sheet workpiece will fall off fine burrs on the equipment due to the extrusion effect during stamping and forming, which is not only inconvenient to clean, but also difficult to ensure safety performance, and it is easy to stab the hand. Using the embodiment of the present invention, the stamping and forming equipment is first placed next to the feeding machine equipment, and the galvanized steel sheet workpiece is The workpiece is placed on the feeder. After the feeder equipment is started, the galvanized steel sheet workpiece is transported to the top of the punching table 9. At this time, the motor of the feeder is stopped, and the cylinder 4 is started. The high-pressure gas generated by the compressor is used to transport the compressed gas to the piston rod 5. The piston rod 5 moves downward to squeeze the solenoid valve 6 and the punch 7. The solenoid valve 6 and the punch 7 move downward to punch the galvanized steel sheet workpiece. After being punched, the galvanized steel sheet workpiece contacts the forming component. By starting the forming component, the galvanized steel sheet workpiece is pressed down, twisted, and brought close to the galvanized steel sheet workpiece, and the galvanized steel sheet workpiece is squeezed into a specified shape; After completing a stamping process, the formed galvanized steel sheet workpiece will be left inside the equipment. In order to facilitate the next use, the formed galvanized steel sheet workpiece needs to be removed, that is, the driving force when the punch 7 is pressed down is used to make the punch 7 drive the lower pressure piece 61 to move synchronously downward, and the lower pressure piece 61 moves downward to squeeze the pushing component, and the pushing component is triggered to start working. At this time, the pushing component will first move downward with the lower pressure piece 61. When the pushing component moves to the bottom end of the support plate 3, the pushing component is flush with the height of the remaining workpiece. After the pushing component senses the position of the formed galvanized steel sheet workpiece, the pushing component starts and extends the electric telescopic cylinder 84 to push out the galvanized steel sheet workpiece formed inside the stamping table 9, thereby facilitating the next use; it should be noted that the loading machine equipment is a prior art and will not be described in detail.

[0024] After the formed galvanized steel sheet workpiece is pushed out, it will fall forward. Although the recycling box can be used to complete the recycling, the galvanized steel sheet workpiece will be deformed when being punched, and the surface will fall off during the deformation to form burrs, which will remain at the bottom of the equipment. The burrs need to be processed after recycling, and it is difficult to process the burrs simultaneously during recycling. Therefore, when the punch 7 is pressed down, the recycling component will be pushed to move simultaneously. The punch 7 presses down to push the recycling component forward, and when it moves forward, it detaches from the initial position above the formed galvanized steel sheet workpiece and slides to The final position of the outer edge of the bottom wall of the punching table 9 is that after the stamping is completed, the punch 7 is pressed down and reset upward to reset the formed galvanized steel sheet workpiece to its original position; it should be noted that the action of the solenoid valve 6 is controlled by the existing foot switch or double-button switch; when recovering the formed galvanized steel sheet workpiece and burrs, it is necessary to start from the outlet of the bottom wall of the punching table 9, and after fitting the outer edge of the bottom wall of the punching table 9, block the fallen burrs to ensure that the burrs do not remain at the bottom of the equipment, and then cooperate with the reciprocating action to complete the recovery.

[0025] Combination Figure 1 , Figure 2 , Figures 7 and 8 As shown: the recovery component includes an inclined block 601 installed on both sides of the solenoid valve 6, and a receiving rod 602 is fixedly connected to the front of the two inclined blocks 601, and a swing bar 603 is fixedly connected to the bottom end of the receiving rod 602. The top of the swing bar 603 is transferred to an assembly plate 604, and a fixing frame 605 is fixedly connected to the middle of the bottom of the assembly plate 604. A discharge hopper 606 is transferred between the two swing bars 603, and a recovery box is arranged on the side of the discharge hopper 606 away from the solenoid valve 6; bolts are connected through the inner cavity of the swing bar 603 and the inner wall of the assembly plate 604, and the bolts are used to assist the deflection of the swing bar 603. The initial position of the discharge hopper 606 is located directly above the galvanized steel sheet workpiece stamped on the top of the stamping table 9. After being pushed by the receiving rod 602, the discharge hopper 606 will move to a position where the bottom wall of the stamping table 9 is flush with the outer edge; the punch 7 is in the shape of a "light bulb", and the size of the punch 7 is adapted to the opening in the middle of the stamping table 9; During operation, after the galvanized steel sheet workpiece is stamped and formed, it is necessary to recycle the formed galvanized steel sheet workpiece. During collection, burrs will remain at the bottom of the equipment, making it difficult to recycle the two synchronously at one time. Using the embodiment of the present invention, the piston rod 5 moves downward, the piston rod 5 squeezes the solenoid valve 6, the punch 7 moves, the solenoid valve 6 moves linearly downward, the solenoid valve 6 drives the inclined block 601 and the receiving rod 602 to move, the receiving rod 602 first squeezes the swing bar 603 to move forward, the swing bar 603 drives the discharge hopper 606 to move synchronously, the initial position of the discharge hopper 606 is above the galvanized steel sheet workpiece, which is convenient for protecting the stamping position, and the discharge hopper 606 gradually separates from the initial position after movement, and the material is discharged. The hopper 606 moves to the outer edge of the bottom wall of the stamping table 9, reserving the position for stamping and forming. At this time, the punch 7 presses down to complete the stamping and forming process of the galvanized steel sheet workpiece, and the formed galvanized steel sheet workpiece and the burrs remaining from the stamping and forming fall into the discharge hopper 606, and will move downward along the inner wall of the discharge hopper 606, and finally be collected in the recycling box at the other end through the discharge hopper 606; after the processing is completed, as the punch 7 rises, the discharge hopper 606 is reset to its initial position, blocking the stamping and forming position, thereby protecting the position of the stamped galvanized steel sheet workpiece, and at the same time facilitating the synchronous recovery of the formed galvanized steel sheet workpiece and the burrs detached due to stamping and forming.

[0026] Combination Figures 5 to 7 As shown, the forming assembly includes two positioning plates 91 installed on the top of the punching table 9, two fixed shafts 92 are fixedly connected to the front of the front of the punching table 9, the outer periphery of the two fixed shafts 92 are fixedly connected with tension springs 93, and the top of the tension spring 93 is fixedly connected with a fixed shaft 2 94, and the inside of the punching table 9 has two transfer dies 95; there is a space reserved between the die 95 and the bottom of the through groove of the punching table 9, the bottom of the positioning plate 91 has a positioning pin, and the top of the punching table 9 is provided with a hole corresponding to the positioning pin, and the positioning pin is used to insert into the hole to form a positioning; the die 95 is a combined shape, and the inner surface of the die 95 is adapted to the outer surface of the punch 7.

[0027] During operation, in the process of stamping the galvanized steel sheet workpiece, the stamping process often requires multiple operation steps such as blanking, punching, and stretching. It is difficult to perform one-time forming processing on complex movements. Even if there is a one-time forming stamping equipment, the cost is relatively expensive and is not suitable for small galvanizing workshops. Using the embodiment of the present invention, first adjust the positioning plate 91 to a suitable position, and then insert the positioning pin into the top of the stamping table 9. After adjusting the position, the galvanized steel sheet workpiece is conveyed between the two positioning plates 91. At this time, the compressor is driven, and the compressor conveys compressed air to the cylinder 4. The cylinder 4 pushes the piston rod 5 to move. The piston rod 5 squeezes the solenoid valve 6 and the punch 7 to move synchronously. The punch 7 presses down in the direction of the galvanized steel sheet workpiece. As the punch 7 continues to press down, the galvanized steel sheet workpiece moves downward from the middle of the stamping table 9, and the galvanized steel sheet workpiece is deformed. , and gradually sinks downward, the punch 7 pushes the die 95 to move downward, the die 95 moves downward and contacts the inner bottom wall of the through groove of the punching table 9, the die 95 drives the fixed shaft 2 94 to move synchronously, the fixed shaft 2 94 drives the stretching spring 93 to move, the stretching spring 93 gradually becomes longer, and the fixed shaft 1 92 supports the stretching spring 93, the inner bottom wall of the punching table 9 is pressed down by the die 95 and blocked, and the two dies 95 are squeezed toward the middle close to the galvanized steel sheet workpiece. After the galvanized steel sheet workpiece is squeezed close together, the two sides of the galvanized steel sheet workpiece are folded toward the middle and fit on the side of the punch 7. Under the action of the two dies 95 squeezing toward the middle, the galvanized steel sheet workpiece is gradually stamped into a shape corresponding to the punch 7, simplifying the cumbersome steps of bending, pressing holes, and interlacing, with the function of one-time stamping forming, so that the equipment has the effect of rapid stamping forming.

[0028] Combination Figures 3 to 5 As shown: the pushing assembly includes a limiting cylinder 81 installed in the middle of the front of the extrusion seat 8, the limiting cylinder 81 is connected to the electric telescopic cylinder 84, a controller 83 is installed on the back of the extrusion seat 8, a sensor 82 is fixed to the bottom of the extrusion seat 8, and a sensing seat 85 is clamped at the bottom of the sensor 82; the outer part of the electric telescopic cylinder 84 is slidably connected to the limiting cylinder 81, and the electric telescopic cylinder 84 penetrates the extrusion seat 8 and is connected to the controller 83; a circular groove corresponding to the electric telescopic cylinder 84 is opened in the middle of the limiting cylinder 81, and an electromagnetic block that is convenient for embedding in the support plate 3 is installed in the extrusion seat 8; During operation, when the punch 7 is stamping the galvanized steel sheet downward, although the punch 7 can stamp the galvanized steel sheet, the galvanized steel sheet formed after stamping still remains in the two concave dies 95, and may even be tightly embedded in the stamping table 9 due to the strong stamping force. If the material is not removed in time, it will cause an obstacle to the next stamping. When the solenoid valve 6 moves linearly downward, the solenoid valve 6 drives the pressing piece 61 to move synchronously, and the pressing piece 61 moves downward to squeeze the extrusion seat 8, and the extrusion seat 8 gradually slides downward along the side wall of the support plate 3, and the controller 83 and the sensor 82 gradually move synchronously with the extrusion seat 8, and the sensor 82 is gradually inserted into the interior of the sensing seat 85. When the sensor 82 and the induction seat 85 are connected, when the extrusion seat 8 slides to a position flush with the galvanized steel plate discharge port, the electromagnetic block is inserted into the support plate 3 and stops to form a positioning, and the electrical signal of the movement of the extrusion seat 8 is fed back to the inside of the controller 83. The controller 83 inputs the electrical signal to the electric telescopic cylinder 84. After the electric telescopic cylinder 84 is energized, it gradually becomes longer and extends from the inside of the limit cylinder 81. The electric telescopic cylinder 84 is in the shape of a circular ring. The electric telescopic cylinder 84 gradually pushes the galvanized steel plate forward. After the galvanized steel plate is pushed out, it is convenient for normal use next time. It should be noted that the induction seat 85 feeds back the stamping height to the sensor 82, so that when the subsequent electric telescopic cylinder 84 is extended, it will not be misaligned with the formed galvanized steel plate.

[0029] Working principle: In the process of stamping galvanized steel sheet workpieces, stamping often requires multiple operation steps such as blanking, punching, and stretching. It is difficult to perform one-time forming on complex movements. Even if there is a one-time forming stamping equipment, the cost is relatively expensive and is not suitable for small galvanizing workshops. Using the embodiment of the present invention, first adjust the positioning plate 91 to a suitable position, and then insert the positioning pin into the top of the stamping table 9. After adjusting the position, the galvanized steel sheet workpiece is conveyed between the two positioning plates 91. At this time, the compressor is driven, and the compressor conveys compressed air to the cylinder 4. The cylinder 4 pushes the piston rod 5 to move. The piston rod 5 squeezes the solenoid valve 6 and the punch 7 to move synchronously. The punch 7 presses down in the direction of the galvanized steel sheet workpiece. As the punch 7 continues to press down, the galvanized steel sheet workpiece moves downward from the middle of the stamping table 9, and the galvanized steel sheet workpiece is formed. The punch 7 pushes the die 95 to move downward, and the die 95 moves downward to contact the inner bottom wall of the through groove of the punching table 9. The die 95 drives the fixed shaft 2 94 to move synchronously, and the fixed shaft 2 94 drives the stretching spring 93 to move. The stretching spring 93 gradually becomes longer, and the fixed shaft 1 92 supports the stretching spring 93. The inner bottom wall of the punching table 9 is blocked after being pressed down by the die 95. The two dies 95 are squeezed toward the middle close to the galvanized steel workpiece. After the galvanized steel workpiece is squeezed close together, the two sides of the galvanized steel workpiece are folded toward the middle and fit on the side of the punch 7. Under the action of the two dies 95 squeezing toward the middle, the galvanized steel workpiece is gradually stamped into a shape corresponding to the punch 7, simplifying the cumbersome steps of bending, pressing holes, and interlacing, and having the function of one-time stamping and forming, thereby enabling the equipment to have the effect of rapid stamping and forming; During the process of the punch 7 stamping the galvanized steel sheet downward, although the punch 7 can stamp the galvanized steel sheet, the galvanized steel sheet formed after stamping still remains in the two concave dies 95, and may even be tightly embedded in the stamping table 9 due to the strong stamping force. If the material is not removed in time, it will cause an obstacle to the next stamping. When the solenoid valve 6 moves linearly downward, the solenoid valve 6 drives the pressing piece 61 to move synchronously, and the pressing piece 61 moves downward to squeeze the extrusion seat 8, and the extrusion seat 8 gradually slides downward along the side wall of the support plate 3, and the controller 83 and the sensor 82 gradually move synchronously with the extrusion seat 8, and the sensor 82 is gradually inserted into the interior of the sensing seat 85. At this time, the sensor The sensor 82 and the induction seat 85 are connected. When the extrusion seat 8 slides to a position flush with the discharge port of the galvanized steel plate, the electromagnetic block is inserted into the support plate 3 and stops to form a position. The electric signal of the movement of the extrusion seat 8 is fed back to the inside of the controller 83. The controller 83 inputs the electric signal to the electric telescopic cylinder 84. After the electric telescopic cylinder 84 is energized, it gradually becomes longer and extends from the inside of the limit cylinder 81. The electric telescopic cylinder 84 is in the shape of a ring. The electric telescopic cylinder 84 gradually pushes the galvanized steel plate forward. After the galvanized steel plate is pushed out, it is convenient for normal use next time. It should be noted that the induction seat 85 feeds back the stamping height to the sensor 82, so that the subsequent electric telescopic cylinder 84 will not be misaligned with the formed galvanized steel plate when it is extended; After the galvanized steel sheet workpiece is stamped and formed, it is necessary to recycle the formed galvanized steel sheet workpiece. During collection, burrs will remain at the bottom of the equipment, making it difficult to recycle the two synchronously at one time. Using the embodiment of the present invention, the piston rod 5 moves downward, the piston rod 5 squeezes the solenoid valve 6, the punch 7 moves, the solenoid valve 6 moves linearly downward, the solenoid valve 6 drives the inclined block 601 and the receiving rod 602 to move, the receiving rod 602 first squeezes the swing bar 603 to move forward, the swing bar 603 drives the discharge hopper 606 to move synchronously, the initial position of the discharge hopper 606 is above the galvanized steel sheet workpiece, which is convenient for protecting the stamping position, and the discharge hopper 606 gradually separates from the initial position after movement. 06 moves to the outer edge of the bottom wall of the stamping table 9, reserving the position for stamping and forming.
