[0024] As Figure 3 shown in the utility model embodiment, a novel steel plate shearing machine is provided, which comprises a body 1, a shearing unit, a cutter 2 movably arranged on the body 1 and a driving member arranged on the body 1 and used for driving the cutter 2 to reciprocate up and down, a limiting unit comprising a fixed seat 102 fixedly arranged on one side of the body 1 and a movable seat 4 arranged on the body 1 through an adjusting device and away from one end side of the fixed seat 102, at least two sets of limit wheels 401 are rotatably arranged on the fixed seat 102 and the movable seat 4, the movable seat 4 is driven by the adjusting device to be away from or close to the fixed seat 102 on the body 1, and the multiple sets of limit wheels 401 are respectively abutted against two side edges of the steel plate to be sheared.

[0025] The detailed working process of the embodiment is as follows: under the setting of the adjusting device, the movable seat 4 is adjusted to adapt to steel plates of different widths, the movable seat 4 is threadedly connected with the screw rod 5, the movable seat 4 is driven to move close to or away from the fixed seat 102 in the stroke groove 105 by rotating the screw rod 5, the distance between the movable seat 4 and the fixed seat 102 is changed, and the end, away from the machine body 1, of the screw rod 5 is provided with a turbine 502, the worm 501 is engaged with the turbine 502 and arranged on the machine body 1, the turbine 502 is rotated by rotating the worm 501, the screw rod 5 is rotated by the turbine 502, the movable seat 4 is driven to move close to or away from the fixed seat 102 in the stroke groove 105, and the limiting wheels 401 are respectively abutted on both sides of the steel plate, so that the steel plate is limited and fixed, and the worm and gear mechanism has the ability to prevent reverse rotation. The realization of this self-locking mainly depends on the friction coefficient between the worm screw angle and the worm and gear. When the worm screw angle (or called lead angle) is less than the friction angle (or called equivalent friction angle) between the worm and gear, the worm and gear mechanism has self-locking, that is, the movable seat 4 is prevented from loosening by itself and affecting positioning.

[0026] As shown in Figure 2 With Figure 3 As shown, the machine body 1 is detachably provided with a mounting seat 103, and the mounting seat 103 and the movable seat 4 are both rotationally provided with conveying wheels 403.

[0027] The detailed working process of the embodiment is as follows: the conveying wheel 403 is used to reduce the friction between the steel plate and the machine body 1 during movement, and to reduce the work burden of workers.

[0028] As shown in Figure 2 The machine body 1 is symmetrically provided with guide rails 101 on both sides, and the cutting knives 2 are respectively located in the corresponding guide rails 101.

[0029] The detailed working process of the embodiment is as follows: the guide rail 101 is used to limit the cutting knife 2, so that the cutting knife 2 moves along the extension direction of the guide rail 101.

[0030] As shown in Figure 2 The driving member includes a crankshaft 201 rotationally arranged on the machine body 1, and a connecting arm 202 rotationally arranged on the crankshaft 201, the connecting arm 202 is movably connected with the cutting knife 2, and the side, close to the limiting unit, of the cutting knife 2 is provided with a pressing unit for pressing the steel plate.

[0031] The detailed working process of the embodiment is as follows: the crankshaft 201 is drivingly connected with the driving device, the crankshaft 201 is rotated on the machine body 1 by the driving device, so as to drive the cutting knife 2 to reciprocate along the extension direction of the guide rail 101.

[0032] As shown in Figure 2As shown, the pressing unit comprises a pressing strip 3, two upright columns 301 are arranged on the pressing strip 3, two mounting arms 203 are arranged on the side of the cutter 2 close to the limiting unit, the two upright columns 301 are movably arranged on the corresponding mounting arms 203 respectively, and a compression spring 302 is sleeved on each upright column 301, and the two compression springs 302 are located between the corresponding mounting arms 203 and the cutter 2.

[0033] The detailed working process of the embodiment is as follows: the pressing strip 3 is used for pressing and fixing one end of the steel plate to be cut, so as to avoid displacement of the steel plate during cutting and affect the cutting quality; when the cutter 2 moves downward to cut the steel plate, the pressing strip 3 will first contact and abut against the steel plate, and then the cutter 2 cuts off; at this time, the compression spring 302 stores energy; when the cutter 2 moves away, the pressing strip 3 will continue to abut under the elastic force of the compression spring 302; only when the cutter 2 moves away by a certain distance, the pressing strip 3 will leave the steel plate, and then the steel plate can be moved.

[0034] As shown in the figure, Figure 2 A rubber pad 303 is arranged on the cutter 2.

[0035] The detailed working process of the embodiment is as follows: the rubber pad 303 increases the contact stability of the pressing strip 3 and the steel plate.

[0036] As shown in the figure, Figure 2 A scale line 104 is arranged on the machine body 1, and the scale line 104 is located on one side of the stroke groove 105.

[0037] The detailed working process of the embodiment is as follows: under the arrangement of the scale line 104, the movable seat 4 can be adjusted intuitively.

[0038] As shown in the figure, Figure 2 The cutting edge of the cutter 2 forms an angle with the horizontal line along the length direction of the cutting edge.

[0039] The detailed working process of the embodiment is as follows: when the cutting edge forms an angle with the steel plate, the cutting efficiency is higher. Because the cutting edge can cut into the steel plate more quickly, the cutting time and the required cutting force are reduced.

[0040] The implementation principle of the embodiment is as follows: first, the movable seat 4 is adjusted according to the width of the steel plate; after the appropriate position is adjusted, the steel plate is sent into the cutting area between the movable seat 4 and the fixed seat 102; then the crankshaft 201 is driven to rotate, so as to control the cutter 2 to cut the steel plate.
