Description

Technical Field

[0001] The utility model relates to the technical field of punching and shearing machines, in particular to a steel plate punching and shearing machine. Background Art

[0002] Steel is a material made of ingots, billets or steel through pressure processing into various shapes, sizes and properties required. Steel has a very wide range of applications, from construction, machinery manufacturing to light industrial products. With the development of the times, steel is now also widely used in the furniture field, such as various metal cabinets, metal sofas, coffee tables and artworks. The application of steel in the furniture field also requires stamping, cutting and other processes. After the steel is processed into plates, the plates need to be punched, notched or bent, and the punching and shearing machine is an indispensable equipment. The staff can achieve the punching, notching and bending of the plates by replacing the punching and shearing heads.

[0003] However, during use, existing punching and shearing machines are often designed with a discharge groove on the lower side of the support block to facilitate the discharge of waste generated when punching or notching the plate. Since the plate is subjected to downward pressure from the punching and shearing head during the punching and shearing process, and the middle part of the plate has no upward support force at this time, the plate can only resist the downward pressure of the punching and shearing head by its own rigidity. If it encounters a thinner plate, it will cause the plate to bend and deform, thereby causing damage to the plate or even scrapping. Utility Model Content

[0004] In response to the shortcomings of existing punching and shearing machines, the utility model provides a steel plate punching and shearing machine, which has the advantages of buffering the pressure applied by the punching shear head, preventing the plate from bending and deformation, increasing the supporting force of the plate, and prompting the punching shear head to be quickly pulled out of the punching and shearing hole of the plate, thereby improving the punching and shearing efficiency, and solving technical problems such as bending of the plate due to the pressure of the punching shear head.

[0005] The utility model provides the following technical solution: a steel plate punching and shearing machine, comprising a punching and shearing machine body, and further comprising:

[0006] A reinforcing plate is fixedly mounted on the bottom of both sides of the punching and shearing machine body, a support block is fixedly connected to the top surface of the lower part of the punching and shearing machine body, a driving cavity is opened inside the upper side of the punching and shearing machine body, a motor is fixedly mounted on the middle part of the side wall of the driving cavity of the punching and shearing machine body, a crankshaft is fixedly connected to the output end of the motor, the crankshaft is inside the driving cavity, a sleeve is rotatably sleeved in the middle part of the crankshaft, and a connecting rod is fixedly connected to the bottom of the sleeve;

[0007] A limiting groove is provided inside the punching and shearing machine body and is located on the lower side of the driving cavity. A slider is slidably connected inside the limiting groove. The middle part of the top surface of the slider is hinged to the bottom end of the connecting rod through a hinge. A punching and shearing head is fixedly installed in the middle part of the bottom surface of the slider. A plate is placed on the upper side of the punching and shearing head. A discharge groove is provided on the inner side of the support block at the lower part of the punching and shearing machine body.

[0008] Preferably, the interior of the punching and shearing machine body includes:

[0009] The movable cavity is provided inside the lower side of the punching and shearing machine body and is located below the support block;

[0010] a magnetic block, fixedly connected to the bottom surface of the active cavity;

[0011] The magnetic slide is slidably connected to the interior of the movable cavity.

[0012] Preferably, the magnetic slide includes:

[0013] The L-shaped plate is fixedly connected to the middle of the top surface of the magnetic slide. The upper part of the L-shaped plate extends out of the movable cavity. The magnetism of the magnetic block is opposite to that of the magnetic slide.

[0014] Preferably, the slider includes:

[0015] a magnetic plate fixedly disposed inside the slider;

[0016] The electromagnetic coil is fixedly arranged inside the punching and shearing machine body and located outside the limiting groove.

[0017] Preferably, the punching and shearing machine body further includes:

[0018] A fixed plate, fixedly connected to the bottom surface of the upper portion of the punching and shearing machine body and located at the rear side of the discharge chute;

[0019] an electromagnet fixedly connected to the lower portion of the fixed plate;

[0020] A chute is provided inside the fixed plate and is located below the electromagnet;

[0021] a magnetic slider, slidably connected to the interior of the slide groove;

[0022] The electromagnet is electrically connected to the output end of the electromagnetic coil through a wire, and the magnetism of the electromagnet is opposite to that of the magnetic slider.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By designing the movable cavity, magnetic block, magnetic slide and L-shaped plate, when the plate is placed on the support block for punching and shearing, the staff manually lifts the L-shaped plate and then places the plate on the lower side of the L-shaped plate. After that, the magnetic slide at the bottom of the L-shaped plate will be affected by the magnetic attraction of the magnetic block, causing the magnetic slide to slide downward. Since the L-shaped plate is pressed on both sides of the plate at this time, the two sides of the plate will be subjected to downward pulling force. However, after the two sides of the plate are subjected to pulling force, the middle part of the plate will generate an upward internal force due to the pulling force on both sides, thereby offsetting the pressure applied by the punching shear head and preventing the plate from bending.

[0025] 2. By designing the magnetic plate, electromagnetic coil, fixed plate, electromagnet and magnetic slider, when the punching shear head presses down to punch and shear the sheet, the slider will drive the magnetic plate to move downward, so that an electromagnetic effect is generated between the magnetic plate and the electromagnetic coil, so that the current generated by the electromagnetic coil is transmitted to the electromagnet, and the electromagnet will adsorb the magnetic slider after being magnetized, so that the sheet will be clamped between the magnetic slider and the electromagnet, and the magnetic slider will support the sheet and offset the pressure applied by the punching shear head as much as possible to prevent the sheet from bending and deformation.

[0026] 3. By designing the magnetic plate, electromagnetic coil, fixed plate, electromagnet and magnetic slider, when the punching and shearing of the plate is completed, the electromagnet is located above the plate, so that the electromagnet will limit the plate, and the punching shear head will slide upward at this time. The limit of the electromagnet allows the punching shear head to be quickly pulled out from the punching and shearing hole on the plate, avoiding the punching and shearing head from being stuck on the punching and shearing hole of the plate, thereby improving the punching and shearing efficiency of the plate.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-4 The cam 7 is fixed on the top of the cam 7 and the bottom of the cam 7 is fixed on the top of the cam 7. The cam 7 is fixed on the top of the cam 7 and the bottom of the cam 7 is fixed on the top of the cam 7.

[0034] See also Figures 1-4 A movable cavity 31 is provided inside the lower side of the punching and shearing machine body 1, below the support block 3. A magnetic block 32 is fixedly welded to the bottom surface of the movable cavity 31, and a magnetic slide 33 is slidably connected to the inside of the movable cavity 31 to ensure that the magnetic block 32 can adsorb the magnetic slide 33, so that the magnetic slide 33 slides down.

[0035] See also Figures 1-4 An L-shaped plate 34 is fixedly welded to the middle of the top surface of the magnetic slide 33, and the upper part of the L-shaped plate 34 extends out of the movable cavity 31. The magnetism of the magnetic block 32 is opposite to that of the magnetic slide 33, ensuring that the magnetic slide 33 slides down and applies a downward pulling force to the L-shaped plate 34, thereby utilizing the contact between the L-shaped plate 34 and the plate 12 to make the downward pulling force act on the plate 12.

[0036] See also Figures 1-4 A magnetic plate 101 is fixedly provided inside the slider 10, and an electromagnetic coil 102 is fixedly provided inside the punching and shearing machine body 1 on the outside of the limiting groove 9 to ensure that an electromagnetic effect can be generated between the magnetic plate 101 and the electromagnetic coil 102.

[0037] See also Figures 1-4The bottom surface of the upper part of the punching and shearing machine body 1 is located on the rear side of the discharge trough 13 and is fixedly welded with a fixed plate 131. The lower part of the fixed plate 131 is fixedly welded with an electromagnet 132. The interior of the fixed plate 131 is located at the lower side of the electromagnet 132 and is provided with a slide groove 133. The interior of the slide groove 133 is slidably connected with a magnetic slider 134. The electromagnet 132 is electrically connected to the output end of the electromagnetic coil 102 through a wire. The magnetism of the electromagnet 132 is opposite to that of the magnetic slider 134, ensuring that the magnetic slider 134 can support the plate 12, and the electromagnet 132 can also limit the plate 12, so that after the punching and shearing of the plate 12 is completed, the punching and shearing head 11 can be smoothly pulled out of the punching and shearing hole on the plate 12.

[0038] When the plate 12 needs to be punched and sheared, the staff lifts the L-shaped plate 34, places the plate 12 on the support block 3 and places it on the lower side of the L-shaped plate 34, and then loosens the L-shaped plate 34. After that, the magnetic slide 33 at the bottom of the L-shaped plate will be affected by the magnetic attraction of the magnetic block 32, causing the magnetic slide 33 to slide downward, so that the L-shaped plate 34 will fix the plate 12, and then turn on the motor 5. The motor 5 drives the crank shaft 6 to rotate, and through the cooperation of the sleeve 7 and the connecting rod 8, the slider 10 will slide up and down inside the limit groove 9. When the slider 10 slides down, the slider 10 will drive the punching shear head 11 to move down and punch and shear the plate 12. Since the L-shaped plate 34 is pressed on both sides of the plate 12 at this time, the two sides of the plate 12 will be subjected to downward pulling force. However, after the two sides of the plate 12 are subjected to pulling force, the middle part of the plate 12 will generate an upward internal force due to the pulling force on both sides, thereby offsetting the pressure applied by the punching shear head 11, preventing the plate 1 2 bending, while the slider 10 is moved up and down in the limiting groove 9, an electromagnetic effect is generated between the magnetic plate 101 and the electromagnetic coil 102, so that the current generated by the electromagnetic coil 102 is transmitted to the electromagnet 132, and the electromagnet 132 is magnetized and attracts the magnetic slider 134, so that the magnetic slider 134 and the electromagnet 132 clamp the sheet 12, and the magnetic slider 134 supports the sheet 12 and offsets the pressure applied by the punching shear head 11 as much as possible to prevent the sheet 12 from bending and deforming. Secondly, when the punching and shearing of the sheet 12 is completed, since the electromagnet 132 is above the sheet 12, the electromagnet 132 limits the sheet 12, and the punching shear head 11 at this time slides upward, and the limit of the electromagnet 132 is used to quickly pull the punching shear head 11 out of the punching hole on the sheet 12, thereby preventing the punching shear head 11 from being stuck on the punching hole of the sheet 12, thereby improving the punching and shearing efficiency of the sheet 12.
