Description

Technical Field

[0002] A shearing machine is a machine that uses one blade to make reciprocating linear motion relative to another blade to shear plates. It uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shearing force to metal plates of various thicknesses, so that the plates can be broken and separated according to the required size. A shearing machine is a type of forging machinery. Its main function is in the metal processing industry. Its products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electricity, electrical appliances, decoration and other industries to provide the required special machinery and complete equipment.

[0003] During operation, most existing shearing machines use multiple hydraulic mechanisms to press the plates at multiple fixed points and then shear them. During the shearing process, plates with special materials (especially thin plates) will inevitably deform due to the difference in force between the shearing machine and the hydraulic mechanism, resulting in the final sheared plates not meeting the process requirements.

DETAILED DESCRIPTION

[0019] Please refer to the attached Figure 1-Figure 2 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] The utility model proposes a material pressing mechanism for a CNC shearing machine. Before use, a pair of limit plates 11 are at the farthest relative position, a pair of lifting plates 14 and a lifting plate 2 3 are at the highest position. When using the device, a plate is placed on a workbench, one end of the plate is passed through one end of the feed port of a shell 1, and after one end of the plate is passed through the other end of the feed port, a motor 8 is started, the motor 8 drives a lead screw 10 to rotate, the lead screw 10 drives a pair of sliders 9 to slide in a direction close to each other along the groove, the pair of sliders 9 drive the corresponding limit plates 11 to slide in a direction close to each other, and the pair of limit plates 11 slide along the workbench to close to each other The pair of limiting plates 1 drive the corresponding straight groove plates 15 to slide in the direction of approaching each other, the pair of straight groove plates 15 drive the corresponding lifting plates 14 to slide in the direction of approaching each other, and the pair of lifting plates 14 drive the corresponding guide rods 4 to slide in the through groove in the direction of approaching each other. When the opposite side of the pair of limiting plates 1 is in contact with one side of the plate (do not fit tightly, which is inconvenient for subsequent feeding), the motor 1 8 is turned off, and the plates of different widths are limited by the limiting structure, so that the plates are always fed in a straight line motion to avoid the situation that the plates are tilted during shearing, resulting in unqualified shearing. The pair of motors 2 5 are started, and the pair of motors 2 5 drive The corresponding lead screw 26 rotates, and a pair of lead screws 26 drives the corresponding slider 27 to slide downward along the corresponding straight groove plate 15, and a pair of sliders 27 drives the corresponding lifting plate 14 to slide downward, and a pair of lifting plates 14 drives the lifting plate 23 to slide downward through the corresponding guide rod 4. When the lower sides of the two groups of pressing rollers 13 and a group of pressing rollers 2 12 press the upper side of the plate, the pair of motors 25 are turned off, which is convenient for pressing plates of different thicknesses. The two groups of pressing rollers 13 cooperate with a group of pressing rollers 2 12 to replace the traditional multi-point fixing method, which increases the pressing area and avoids deformation caused by the difference in force between the multi-point fixing and the workbench (especially for thinner plates). The plate is pushed (or the plate is pushed by the feeding mechanism), and the plate slides along the workbench and two sets of pressure rollers 13 and one set of pressure rollers 12 toward the direction of the shearing plate assembly 16. Through the cooperation between the limiting structure and the pressing structure, the two sides and the middle of the plate of different widths are limited and pressed to ensure that the plate maintains a straight feeding. At the same time, the pressure rollers 13 and 12 can roll to make the plate feeding smoother. If the plate is thicker and heavier, the limiting structure can be directly started, and the plate itself will not be warped due to shearing. After use, the device is restored to its initial state.
