Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically a shearing machine with blade adjustment function. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It utilizes a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. Shearing machines belong to the forging and pressing machinery category and are primarily used in the metal processing industry. Shearing machines are a widely used shearing equipment in machining, capable of shearing steel plates of various thicknesses. Commonly used shearing machines are divided into three types: flat shearing, roller shearing, and vibratory shearing. Products are widely used in industries such as aerospace, light industry, metallurgy, chemical industry, construction, shipbuilding, automotive, power, electrical appliances, and decoration, providing the necessary specialized machinery and complete sets of equipment.

[0003] When processing sheet metal, if the thickness and hardness of the sheet metal do not vary within a large range, the shearing machine can use the same blade gap. However, when the thickness and hardness of the sheet metal vary too much, it is necessary to adjust the blade gap of the shearing machine to prevent burrs from forming during sheet metal processing and to improve the quality of sheet metal processing. Therefore, a shearing machine with blade adjustment function is proposed. Utility Model Content

[0025] Example

[0026] Please see Figure 1-5 This utility model provides a technical solution: a shearing machine with blade adjustment function, including a support base 1, a base 2 installed on the top of the support base 1, an adjustment component installed on the base 2, and a positioning component provided on one side of the base 2.

[0027] By setting an adjustment component, the distance between the lower blade 5 and the upper blade 15 can be adjusted to meet the shearing of plates of different thicknesses and prevent burrs from appearing on the sheared plates. The adjustment component includes a lead screw 4, a lower blade 5, and a worm gear 6. The top of the base 2 has a mounting groove 3. The lead screw 4 is rotatably connected to the inside of the mounting groove 3. The bottom of the lower blade 5 is installed inside the mounting groove 3 and sleeved on the outside of the lead screw 4. The lower blade 5 abuts against the top of the base 2. The lower blade 5 is threaded to the outside of the lead screw 4. The worm gear 6 is fixedly sleeved on the outside of the lead screw 4. The mounting groove 3... The internal rotating connection is a worm gear 7, which is meshed with the outside of the worm wheel 6. One end of the worm gear 7 extends to the outside of the base 2 and is fixedly connected to a turntable 8. The outside of the turntable 8 is provided with an arc-shaped groove 9, and one end of the base 2 is provided with a limit component. By rotating the turntable 8, the worm gear 7 is driven to rotate. The worm gear 7 drives the lead screw 4 to rotate through the worm wheel 6. The lead screw 4 then drives the lower blade 5 to move, thereby adjusting the distance between the lower blade 5 and the upper blade 15. Moreover, the arrangement of the worm wheel 6 and the worm gear 7 can prevent the lead screw 4 from rotating under force, thereby improving the accuracy of plate shearing.

[0028] To prevent burrs from forming during sheet metal cutting, the limiting assembly includes a square guide post 10, a limiting plate 11, and a telescopic spring 12. The square guide post 10 is fixedly connected to one end of the base 2, the limiting plate 11 is movably sleeved on the outside of the square guide post 10, and the outside of the telescopic spring 12 is movably sleeved on the outside of the square guide post 10. One end of the telescopic spring 12 is fixedly connected to one side of the limiting plate 11, and the other end of the telescopic spring 12 is fixedly connected to one end of the base 2. After the cutting blade 5 is adjusted, the limiting plate 11 is released, and the limiting plate 11 will reset under the force of the telescopic spring 12, causing one end of the limiting plate 11 to move into the interior of the arc groove 9, thus completing the limiting of the turntable 8 and preventing the turntable 8 from rotating under external force.

[0029] When the turntable 8 is rotated, the limiting plate 11 is pushed to move outside the square guide post 10. At this time, the telescopic spring 12 is compressed and one end of the limiting plate 11 is disengaged from the inside of the arc groove 9, so that the turntable 8 can be rotated.

[0030] To facilitate the shearing of sheet metal, the positioning assembly includes a sliding column 17, a baffle 18, and a fixing bolt 19. The sliding column 17 is fixedly connected to one side of the base 2. The baffle 18 is movably sleeved on the outside of the sliding column 17. The fixing bolt 19 is threadedly connected to the top of the baffle 18, with one end of the fixing bolt 19 abutting against the outside of the sliding column 17. By rotating the fixing bolt 19 in the opposite direction, one end of the fixing bolt 19 disengages from the outside of the sliding column 17, thereby pushing the baffle 18 to move on the outside of the sliding column 17. The position of the baffle 18 is fixed by measuring the distance between the baffle 18 and the upper blade plate 15. During fixing, the baffle 18 is fixed by rotating the fixing bolt 19 in the forward direction, with one end of the fixing bolt 19 abutting against the outside of the sliding column 17.

[0031] Guide pillars 13 are fixedly connected to both ends of the top of the base 2. A slide 14 is movably sleeved on the outer side of the guide pillars 13. An upper blade 15 is installed on one side of the slide 14. A fixed seat is installed on the top of the guide pillars 13. A cylinder 16 is installed on the top of the fixed seat. The piston rod of the cylinder 16 is installed on the top of the slide 14. During processing, the piston rod of the cylinder 16 extends and pushes the slide 14 to move outside the guide pillars 13. The upper blade 15 on the slide 14 moves downward, which can cut the sheet metal.

[0032] The working principle or structural principle is as follows: based on the thickness of the sheet material, the limiting plate 11 is pushed to move outside the square guide post 10. At this time, the telescopic spring 12 is compressed, and one end of the limiting plate 11 is disengaged from the inside of the arc groove 9. Then, the rotating turntable 8 drives the worm gear 7 to rotate. The worm gear 7 drives the lead screw 4 to rotate through the worm wheel 6. The lead screw 4 drives the lower blade plate 5 to move, thereby adjusting the distance between the lower blade plate 5 and the upper blade plate 15 to meet the shearing of sheet materials of different thicknesses and prevent burrs from appearing on the sheared sheet material. Moreover, the setting of the worm wheel 6 and the worm gear 7 can prevent the lead screw 4 from rotating under force, improving the accuracy of sheet material shearing. After the lower blade plate 5 is adjusted, the limiting plate 11 is released. The limiting plate 11 will be reset under the force of the telescopic spring 12, so that one end of the limiting plate 11 moves into the inside of the arc groove 9, thus completing the limiting of the turntable 8 and preventing the turntable 8 from rotating under external force.

[0033] Next, according to the required cutting dimensions of the sheet material, by rotating the fixing bolt 19 in the reverse direction, one end of the fixing bolt 19 disengages from the outside of the sliding column 17, which pushes the baffle 18 to move outside the sliding column 17. By measuring the distance between the baffle 18 and the upper blade 15, the position of the baffle 18 is fixed. During fixing, by rotating the fixing bolt 19 in the forward direction, one end of the fixing bolt 19 abuts against the outside of the sliding column 17, which completes the fixing of the baffle 18, so as to facilitate the cutting of the sheet material. During processing, the solenoid valve of the cylinder 16 is controlled by the switch group, and the piston rod of the cylinder 16 extends to push the slide 14 to move outside the guide column 13. The upper blade 15 on the slide 14 moves downward, which can cut the sheet material.
