Description

Technical Field

[0001] The utility model belongs to the technical field of plate shearing machines, and in particular relates to a plate shearing machine with an automatic material plate fixing mechanism. Background Art

[0002] CNC shearing machine is based on the traditional shearing machine, using servo motor, reducer, guide rail, slider, etc. as the transmission system. Among them, the servo motor is used as the power source, and the high-speed rotation of the motor is converted into the movement of the cutting mechanical parts through the reducer, which can be controlled by the program. The guide rail and slider ensure the movement accuracy and stability of the cutting mechanical parts.

[0003] CNC shearing machines generally use two opposing blades with a cutting gap in the middle to allow the material to pass through. In particular, the hydraulic gate CNC shearing machines widely used on the market are suitable for shearing of materials such as aluminum plates and thin iron plates.

[0004] After the material plate enters the cutting gap, several cylinders are set on one side of the gate, and the cylinders are used to lower the pressure blocks to press them. However, the stroke of the cylinder is small at the cutting gap, and the instantaneous acceleration is only dependent on the spring buffering means, especially the pressure blocks directly collide with the material plate, which causes obvious noise during the material plate fixing process. For this reason, we propose a shearing machine with an automatic material plate fixing mechanism. Utility Model Content

[0005] The utility model aims to provide a shearing machine with an automatic material plate fixing mechanism, which can buffer the upper surface of the material plate and avoid hard collision in the process of automatically fixing the material plate to reduce noise.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A shearing machine with an automatic material plate fixing mechanism comprises a casing, an upper gate plate is slidably installed inside the casing, the lower edge of the upper gate plate has an inclination and a plurality of cylinders are fixed at intervals, the output ends of the cylinders all extend downward and are all fixed with alloy columns in the axial direction, a coaxial rubber ring is fixed to the lower edge of the alloy column, the height of the lower end of the rubber ring is less than the height of the lower end of the alloy column, when transporting the material plate, the material plate is sent to the cutting gap between two blades by a feeding conveyor belt, the two blades are controlled to approach each other, and the upper gate plate descends with the upper blade, and at the same time, each cylinder is controlled to push the alloy column and the rubber ring downward, and the rubber rings from low to high along the inclined surface of the upper gate plate contact the material plate in turn, and then the rubber ring is squeezed and deformed, so that the alloy column passes through the rubber ring to stick to the material plate and press down, and is fixed by horizontal friction, and the deformed rubber ring is used as a buffer between the upper surface of the material plate and the alloy column, so as to avoid hard collision in the process of automatically fixing the material plate, thereby reducing noise, and compared with the traditional pressing block, the alloy column has a center of gravity coincident with the axis of the cylinder, is not easy to be skewed, and the squeezing effect is more concentrated.

[0008] An alloy tube is sleeved on the outside of the rubber ring, and the upper edge of the alloy tube is fixedly connected to the outside of the alloy column. The height of the lower end of the alloy tube is greater than the height of the lower end of the alloy column. The rubber ring is limited from the outside so that it can be deformed along the gap between the alloy tube and the alloy column to maintain the ring shape.

[0009] An alloy spring is axially sleeved on the outside of the cylinder output end, and the lower end of the alloy spring is connected to the upper surface of the alloy cylinder. The deformation of the alloy spring is used to buffer and reduce shock when the alloy column hits the material plate.

[0010] A metal ring is embedded and installed inside the rubber ring at a position below the cylinder, and tension is performed on the part where the rubber ring is deformed, so that the part maintains a good roundness and avoids distortion and falling under the alloy column to cause obstruction.

[0011] The upper surface of the alloy cylinder is provided with a plurality of air holes, through which air can flow, so as to facilitate the interval between the alloy cylinder and the alloy column to balance the internal air pressure and prevent the deformation of the rubber ring.

[0012] A flange plate is fixed on one side of the alloy cylinder, and a plurality of threaded holes are opened on the flange plate. The metal plate can be fixed with bolts to connect the alloy cylinders in pairs, so that they can be lifted and lowered synchronously with good coordination, and can also straighten each other to reduce the degree of skewness.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a plate shearing machine with an automatic material plate fixing mechanism. When transporting the material plate, the material plate is sent to the cutting gap between two blades through a feeding conveyor belt, the two blades are controlled to approach each other, and the upper gate plate is lowered along with the upper blade. At the same time, each cylinder is controlled to push the alloy column and the rubber ring downward, and the rubber rings from low to high along the inclined surface of the upper gate plate contact the material plate in turn, and then the rubber ring is squeezed and deformed, so that the alloy column passes through the rubber ring to stick to the material plate and press down, and is fixed by horizontal friction. The deformed rubber ring is used as a buffer between the upper surface of the material plate and the alloy column, so that hard collision in the process of automatically fixing the material plate is avoided to reduce noise. In addition, compared with the traditional pressing block, the center of gravity of the alloy column coincides with the axis of the cylinder, so it is not easy to be skewed, and the squeezing effect is more concentrated.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-5 As shown, a shearing machine with an automatic material plate fixing mechanism includes a casing 1, and the casing 1 can be suitable for HT11K series hydraulic gate shearing machines. An upper gate plate 2 is slidably installed inside the casing 1. The upper surface of the upper gate plate 2 is fixedly connected to the hydraulic system of the casing 1 and can move with the upper blade. The lower edge of the upper gate plate 2 has an inclination and a plurality of cylinders 3 are fixed at intervals. The cylinders 3 can use DNC-50-PPVA model pneumatic components and are connected to the air control system of the shearing machine. The output ends of the cylinders 3 all extend downward and are axially fixed with alloy columns 4. A coaxial rubber ring 5 is fixed on the lower edge of the alloy column 4. The height of the lower end of the rubber ring 5 is less than the height of the lower end of the alloy column 4. The shearing machine can be used with a feeding conveyor belt. When transporting the material plate, the material plate is sent to the cutting gap between the two blades through the feeding conveyor belt. The feeding conveyor belt stops and the shearing machine is sheared. The machine controls the two blades to approach each other, and the upper gate plate 2 descends with the upper blade. At the same time, it controls the extension of each cylinder 3 to push the alloy column 4 and the rubber ring 5 downward. The rubber rings 5 ​​from low to high along the inclined surface of the upper gate plate 2 contact the material plate in turn, and then the rubber ring 5 is squeezed and deformed, so that the alloy column 4 passes through the rubber ring 5 to which it belongs, sticks to the material plate and presses down, and is fixed by horizontal friction. At this time, the rubber ring 5 is completely squeezed to the outside of the alloy column 4, and the deformed rubber ring 5 is used as a buffer between the upper surface of the material plate and the alloy column 4 to avoid hard collision during the automatic fixing of the material plate, thereby reducing noise. In addition, compared with the traditional pressing block, the alloy column 4 has a center of gravity coincident with the axis of the cylinder 3, is not prone to skew, and the extrusion effect is more concentrated until the material plate is cut off. Finally, the hydraulic system lifts the upper gate plate 2, and the cylinder 3 lifts the alloy column 4 and the rubber ring 5 to separate from the material plate.

[0024] Different cylinders 3 have different strokes, and the impact effects on the sheet are also different. As the stroke of the cylinder 3 increases, the length of the rubber ring 5 can be adjusted to increase for better buffering. Part of the rubber ring 5 is fixedly connected to the alloy column 4, and when it is deformed, it turns up around the part and can restore its deformation after being separated from the sheet.

[0025] Among them, since the rubber ring 5 is selected for buffering, the cylinder 3 can be replaced with an SXTL model electric push rod telescopic rod, which does not need to connect a special air pump and an adapter, can reduce the number of pipes inside the casing 1, and optimize the internal space layout of the casing 1. In this way, after the electric push rod telescopic rod is extended, it will not drive the alloy column 4 to collide hard with the workbench downward.

[0026] like Figure 1 and Figure 4 As shown, an alloy tube 6 is sleeved on the outside of the rubber ring 5, and the upper edge of the alloy tube 6 is fixedly connected to the outside of the alloy column 4. The height of the lower end of the alloy tube 6 is greater than the height of the lower end of the alloy column 4, and will not collide with the material plate. The rubber ring 5 is limited from the outside so that it can be deformed along the gap between the alloy tube 6 and the alloy column 4, so as to maintain the ring shape.

[0027] like Figure 2 and Figure 4 As shown, an alloy spring 7 is axially sleeved on the outside of the output end of the cylinder 3, and the lower end of the alloy spring 7 is connected to the upper surface of the alloy cylinder 6. The deformation of the alloy spring 7 is used to buffer and reduce shock when the alloy column 4 hits the material plate.

[0028] like Figure 4 and Figure 5 As shown, a metal ring 8 is embedded and installed inside the rubber ring 5 below the cylinder 3, and the deformed part of the rubber ring 5 is tensioned to facilitate the part to maintain good roundness and avoid distortion and falling below the alloy column 4 to cause obstruction.

[0029] like Figure 4 and Figure 5 As shown, a plurality of air holes 9 are provided on the upper surface of the alloy cylinder 6 , through which air can flow, thereby balancing the internal air pressure between the alloy cylinder 6 and the alloy column 4 and preventing the deformation of the rubber ring 5 .

[0030] like Figure 3 and Figure 4 As shown, a flange plate 10 is fixed on one side of the alloy cylinder 6. The flange plate 10 is provided with a plurality of threaded holes, and a metal plate can be fixed by bolts to connect the alloy cylinders 6 in pairs, so that they can be lifted and lowered synchronously with good coordination, and can also straighten each other to reduce the degree of skewness.

[0031] The working principle of the utility model is: when transporting the material plate, the material plate is sent to the cutting gap between the two blades through the feeding conveyor belt, the feeding conveyor belt stops, the shearing machine controls the two blades to approach each other, the upper gate plate 2 drops with the upper blade, and at the same time, each cylinder 3 is controlled to extend, pushing the alloy column 4 and the rubber ring 5 downward, and the rubber ring 5 from low to high along the inclined surface of the upper gate plate 2 contacts the material plate in turn.

[0032] Then the rubber ring 5 is squeezed and deformed, so that the alloy column 4 passes through the rubber ring 5 and sticks to the material plate and presses down, and is fixed by horizontal friction. At this time, the rubber ring 5 is completely squeezed to the outside of the alloy column 4, and the deformed rubber ring 5 is used as a buffer between the upper surface of the material plate and the alloy column 4 to avoid hard collision in the process of automatically fixing the material plate, thereby reducing noise. In addition, compared with the traditional pressing block, the center of gravity of the alloy column 4 coincides with the axis of the cylinder 3, and it is not easy to be skewed, and the squeezing effect is more concentrated.

[0033] Until the material plate is cut off, the hydraulic system finally lifts the upper gate plate 2, and the cylinder 3 lifts the alloy column 4 and the rubber ring 5 to separate from the material plate.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
