Description

Technical Field

[0001] The utility model belongs to the technical field of steel plate bending, and in particular relates to a multifunctional steel plate bending device. Background Art

[0002] Metal materials refer to metal elements or materials with metal properties that are mainly composed of metal elements. Metal materials are a common material with a wide range of uses. When using them, they will be bent to facilitate the use of the bent metal materials. Steel plate is a metal material mainly composed of iron, carbon, etc. It is one of the basic materials for manufacturing many products, such as automobiles, mechanical equipment, building structures, etc. Steel plates have the advantages of high strength, corrosion resistance, and wear resistance, so they are widely used in various industries. Before use, steel plates often need to be bent by a bending device to make them easier to use to meet different needs.

[0003] For example, a Chinese patent with publication number CN210907502U discloses a multifunctional automatic steel plate bending machine, including a supporting frame, a connecting cavity is arranged inside the supporting frame, the left end of the connecting cavity is connected to the rotating shaft through a fixed block, the middle part of the rotating shaft is connected to the first motor through a belt, the first bevel gears are arranged at the upper and lower ends of the rotating shaft, the second bevel gear is meshed with the right side of the first bevel gear, the first threaded rod is arranged on the right side of the second bevel gear, the right side of the first threaded rod is connected to the second connecting rod through a bearing seat, the first connecting block is fixedly installed on the right side of the second connecting rod, the limiting light rod and the second threaded rod are respectively installed on the inner and outer sides of the first connecting block, the first threaded rod is installed with a slider, the second connecting plate is arranged on the upper side of the slider at the lower end, the second connecting plate is arranged on the upper side of the second connecting plate, and the movable bending device is arranged on the lower side of the slider at the upper end. The utility model can realize multiple types of bending processing and facilitate the use of the equipment.

[0004] This patent has some shortcomings when used, such as: when the device in this patent bends the steel plate, due to the lack of positioning structure on both sides of the steel plate, the steel plate is prone to deflection during bending or the bending part deviates from the predetermined bending plan, resulting in poor bending accuracy of the steel plate, making the bent steel plate unable to meet actual use requirements; in addition, when the device in this patent bends the metal material, due to the high hardness of the steel plate, the self-stress at the bending part of the steel plate is large when it is bent, making it difficult to bend the steel plate, and when it is hard bent, the accuracy of the bending part is low. In view of this, we propose a multifunctional steel plate bending device. Utility Model Content

[0054] In this embodiment, the flame spraying nozzle 23 is arranged at an angle, and the flame spraying end of the flame spraying nozzle 23 faces the bending position of the steel plate.

[0055] Among them, the working principle of this device is as follows:

[0056] When in use, place the steel plate flat on the upper surface of the bottom plate 1. It is worth adding that a limit assembly is provided on the right side of the upper surface of the bottom plate 1. The limit assembly includes an L-shaped limit plate, and the limit plate is flush with the edge of the bottom plate 1. The limit plate and the bottom plate 1 are slidably matched. A sliding protrusion is provided on the lower surface of one of the sides of the limit plate. A groove for accommodating the sliding protrusion is provided on the lower surface of the bottom plate 1. A spring fixed to the sliding protrusion is provided in the groove. The spring is used to reset the limit plate. Please refer to the attached manual. Figure 6 and 7 This is a prior art, which should be well known to those skilled in the art, and will not be described in detail in this application; when the steel plate is placed on the bottom plate 1, one side of the steel plate can be against the limiting plate, and the limiting plate ensures that when the steel plate is placed on the upper surface of the bottom plate 1, the steel plate itself will not be skewed;

[0057] Then, the clamping mechanism is started, and the electric push rod 11 in the clamping mechanism works. The telescopic rod of the electric push rod 11 moves downward and drives the extrusion block 12 to move downward, forming a match with the upper surface of the bottom plate 1, so as to realize positioning and clamping with the unbent position of the steel plate, so as to prevent the steel plate from warping and deflecting during the bending process, and ensure the accuracy of the steel plate during bending;

[0058] After the steel plate is fixed, the heating component is started, and the gas is passed through the air inlet end of the upper mold 6, and the gas is sprayed out through the nozzles of multiple flame spray nozzles 23, and multiple pulse igniters 25 are started. Multiple pulse igniters 25 form pulse arcs, and the pulse arcs can ignite the gas, so that multiple flame spray nozzles 23 form high-temperature fire columns, and the fire columns and the steel plate are heated at the bending position, thereby reducing the internal stress at the bending position. The entire heating process only needs to be maintained for 1-3 minutes. The operator can determine the heating time according to the thickness of the steel plate. It is not necessary to heat the steel plate to a red temperature state. Stop supplying gas after heating.

[0059] At this time, the multiple hydraulic cylinders 7 are started, and the telescopic rods of the multiple hydraulic cylinders 7 move downward and push the upper mold 6 to move downward, and the upper mold 6 cooperates with the lower mold 5 to achieve bending of the steel plate;

[0060] When the steel plate needs to be bent at different positions or the clamping mechanism needs to be adjusted according to the size of the steel plate, the moving mechanism is started;

[0061] Start the electric slide rail 13, the sleeve 14 can be displaced in the X-axis direction on the electric slide rail 13, and drive the clamping mechanism below to displace on the steel plate, start the motor 2 18, the output shaft of the motor 2 18 rotates, and drives the threaded rod 16 to rotate. Under the action of the thread force, the threaded block 17 is displaced in the Y-axis direction along the slide groove 15, and drives the X-axis moving component to displace synchronously. When the X-axis moving component is displaced, the clamping mechanism below will also be displaced; in addition, further, in order to meet the bending of the vertical side or inclined side of the steel plate, start the motor 18, the output shaft of the motor 18 rotates, and drives the mounting plate 10, the electric push rod 11 and the extrusion block 12 below to rotate through the coupling 9, so that the steel plate can rotate on the upper surface of the base plate 1, and by setting the coupling 9, the shaking of the output shaft of the motor 18 during rotation is reduced, thereby improving the adjustment accuracy of the steel plate during rotation.

[0062] By setting a clamping mechanism and clamping and restraining the steel plate through the extrusion block 12, it is avoided that the steel plate is lifted and offset at the position away from the bending end when bending, thereby ensuring the accuracy of the steel plate when bending; by setting a heating component, the steel plate is preheated by the flame sprayed by the flame nozzle 23, the softness of the steel plate is improved after heating, and the internal stress at the bending position of the steel plate can be greatly reduced, so that the steel plate is easier to bend and the bending accuracy will not be reduced due to excessive internal stress during the bending process; by setting a moving mechanism, the position of the clamping mechanism in the Y-axis and X-axis directions is changed by using the threaded block 17 and the sliding sleeve 14, so that the device can meet the needs of more accurate clamping and positioning of plates of different sizes, improve the stability and reliability of the clamping mechanism during the clamping process of the steel plate, and improve the accuracy of the device when clamping the steel plate.

[0065] Among them, by providing an anti-skid layer on the lower surface of the extrusion block 12, the friction between the clamping mechanism and the steel plate is increased, ensuring that when the steel plate is rotated by the clamping mechanism, the steel plate can follow the rotation.
