Description

Technical Field

[0001] This utility model relates to the field of sheet metal production technology, specifically to a pressing and molding device for sheet metal production. Background Technology

[0002] Sheet metal refers to standard-sized, flat, rectangular building material panels used in the construction industry for components such as walls, ceilings, or floors. It also often refers to metal sheets that have been forged, rolled, or cast. Sheet metal production requires pressing and shaping, necessitating the use of pressing and shaping equipment.

[0003] Currently, some existing pressing and molding devices cannot automatically push out the molded sheet material, requiring workers to manually remove the pressed sheet material from the mold. This is very inconvenient, causing trouble for workers and reducing work efficiency, thus failing to meet the needs of workers.

[0004] Meanwhile, some existing compression molding devices may encounter problems such as sticking or difficulty in demolding the sheet after molding. Simply using mechanical ejection may cause the edge of the sheet to crack due to uneven local resistance, resulting in economic losses. It will also affect the automatic ejection structure and reduce the practicality of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a pressing and molding device for sheet metal production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressing and forming device for sheet metal production, comprising a worktable and a mold fixedly connected to its top, and further comprising:

[0007] A U-shaped plate is fixedly connected to the top of the workbench. A cylinder is fixedly connected to the top of the inner surface of the U-shaped plate. A pressure plate is fixedly connected to the output end of the cylinder. An L-shaped plate is fixedly connected to the bottom of the workbench. A motor is fixedly connected to the upper surface of the L-shaped plate.

[0008] A push mechanism is installed at the output end of the motor. A bottom template is installed on the top of the push mechanism. A transmission mechanism is installed on the upper surface of the L-shaped plate. A hammer is installed on the top of the transmission mechanism.

[0009] Preferably, the pushing mechanism includes a reciprocating lead screw fixedly connected to the output end of the motor, a slider is mounted on the outer surface of the reciprocating lead screw, a connecting plate is fixedly connected to one side of the slider, and a plurality of push rods are fixedly connected to the top of the connecting plate.

[0010] Preferably, the transmission mechanism includes a transmission rod rotatably connected to the upper surface of the L-shaped plate, a full gear fixedly connected to the outer surface of the transmission rod, a half gear meshing with the full gear, and a torsion spring fixedly connected to the bottom of the worktable.

[0011] Preferably, a buffer sleeve is provided on one side of the striking hammer, and the buffer sleeve is made of rubber.

[0012] Preferably, slide rods are fixedly connected to both sides of the bottom of the workbench, and slide sleeves are slidably connected to the outer surface of the slide rods. One side of the slide sleeves is fixedly connected to one side of the connecting plate.

[0013] Preferably, a limiting sleeve is fixedly connected to the bottom of the slide rod, and the diameter of the limiting sleeve is larger than the diameter of the slide rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the configuration of a motor, a bottom template, and a pushing mechanism, allows the motor to drive the bottom template upwards via the pushing mechanism, automatically ejecting the pressed sheet material. This facilitates direct removal of the sheet material by workers, reducing their workload and improving work efficiency through rapid material removal. Simultaneously, the motor, through the pushing mechanism, drives the bottom template upwards and, via a transmission mechanism, drives a hammer to strike the mold, separating the pressed sheet material from the mold for easy ejection. This prevents the sheet material from cracking at the edges due to uneven local resistance caused by simple mechanical ejection, thus improving the practicality of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a pressing and forming device for sheet metal production includes a workbench 1, a mold 2 fixedly connected to the top of the workbench 1, a U-shaped plate 3 fixedly connected to the top of the workbench 1, a cylinder 4 fixedly connected to the top of the inner surface of the U-shaped plate 3, a pressure plate 5 fixedly connected to the output end of the cylinder 4, and the cylinder 4 pushes the pressure plate 5 downward to perform pressing and forming. An L-shaped plate 7 is fixedly connected to the bottom of the workbench 1, a motor 8 is fixedly connected to the upper surface of the L-shaped plate 7, a pushing mechanism 9 is installed at the output end of the motor 8, and a bottom template 13 is installed on the top of the pushing mechanism 9. The motor 8 drives the bottom template 13 upward through the pushing mechanism 9. The device can automatically eject the pressed and shaped sheet material, making it convenient for workers to remove the sheet material directly, reducing their hassle and improving work efficiency by quickly removing the material. The upper surface of the L-shaped sheet 7 is equipped with a transmission mechanism 6, and the top of the transmission mechanism 6 is equipped with a hammer 12. The motor 8 drives the bottom template 13 to move upward through the pushing mechanism 9, and at the same time drives the hammer 12 through the transmission mechanism 6 to strike the mold 2, which can separate the pressed and shaped sheet material from the mold 2, thus facilitating ejection and preventing the sheet material edges from cracking due to uneven local resistance when using mechanical ejection alone, thereby improving the practicality of the device.

[0023] The pushing mechanism 9 includes a reciprocating lead screw 901 fixedly connected to the output end of the motor 8. A slider 902 is mounted on the outer surface of the reciprocating lead screw 901. A connecting plate 903 is fixedly connected to one side of the slider 902. Several push rods 904 are fixedly connected to the top of the connecting plate 903. The top of the push rods 904 is fixedly connected to the bottom of the bottom template 13. Through the pushing mechanism 9, the motor 8 drives the reciprocating lead screw 901 to rotate. The reciprocating lead screw 901 drives the slider 902 to move upward. The slider 902 drives the connecting plate 903, push rods 904 and bottom template 13 to move upward. This can automatically push out the pressed sheet material, making it convenient for workers to remove the sheet material directly, reducing the trouble for workers, and improving work efficiency by quickly picking up the material.

[0024] The transmission mechanism 6 includes a transmission rod 603 rotatably connected to the upper surface of the L-shaped plate 7. A full gear 602 is fixedly connected to the outer surface of the transmission rod 603, and a half gear 601 is meshed with the full gear 602. The inner surface of the half gear 601 is fixedly connected to the outer surface of the reciprocating lead screw 901. A torsion spring 604 is fixedly connected to the bottom of the worktable 1, and one side of the torsion spring 604 is fixedly connected to the outer surface of the transmission rod 603. Through the transmission mechanism 6, the reciprocating lead screw 901 rotates while simultaneously driving the half gear 601 to rotate, and the half gear 601 drives... The full gear 602 and transmission rod 603 rotate. While the transmission rod 603 rotates, it applies pressure to the torsion spring 604. The transmission rod 603 drives the hammer 12 to strike the mold 2, which can separate the pressed sheet from the mold 2, thus facilitating ejection. This prevents the sheet from cracking at the edge due to uneven local resistance when using mechanical ejection alone, improving the practicality of the device. When the half gear 601 rotates to the gearless position, it releases the pressure on the push rod 904. The push rod 904 can drive the U-shaped plate 3 and the hammer 12 to reset, thus allowing for repeated hammering separation.

[0025] A buffer sleeve is provided on one side of the hammer 12. The buffer sleeve is made of rubber. The rubber buffer sleeve can buffer the impact during the hammering and prevent the excessive impact force from damaging the mold 2.

[0026] Both sides of the bottom of the workbench 1 are fixedly connected to slide rods 10. Slide sleeves 11 are slidably connected to the outer surface of the slide rods 10. One side of the slide sleeves 11 is fixedly connected to one side of the connecting plate 903. Through the slide sleeves 11 and slide rods 10, the connecting plate 903 can be moved up and down, and its movement is more stable.

[0027] A limiting sleeve is fixedly connected to the bottom of the slide rod 10, and the diameter of the limiting sleeve is larger than the diameter of the slide rod 10. By setting the limiting sleeve, the sliding sleeve 11 can be prevented from falling off the slide rod 10 when moving up and down, thereby preventing the connecting plate 903 from being unable to keep moving up and down.

[0028] It is worth noting that the technical features such as mold 2 and pressure plate 5 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0029] Working principle: First, the sheet material to be pressed is placed into mold 2. Then, cylinder 4 is turned on, pushing pressure plate 5 downwards for pressing. Next, motor 8 is turned on, driving reciprocating screw 901 to rotate. Reciprocating screw 901 drives slider 902 upwards, which in turn drives connecting plate 903, push rod 904, and bottom template 13 upwards, automatically ejecting the pressed sheet material. This allows workers to easily remove the sheet material, reducing their workload and improving work efficiency through rapid material removal. Simultaneously, the rotation of reciprocating screw 901 drives the half-gear. When 601 rotates, the half gear 601 drives the full gear 602 and the transmission rod 603 to rotate. While the transmission rod 603 rotates, it applies pressure to the torsion spring 604. The transmission rod 603 drives the hammer 12 to strike the mold 2, which can separate the pressed sheet from the mold 2, thus facilitating ejection. This prevents the sheet from cracking at the edge due to uneven local resistance when using mechanical ejection alone, improving the practicality of the device. When the half gear 601 rotates to the gearless position, it releases the pressure on the push rod 904. The push rod 904 can drive the U-shaped plate 3 and the hammer 12 to reset, thus allowing for repeated hammering separation.
