Description

Technical Field

[0001] The utility model belongs to the technical field of electric shearing machines, and particularly relates to an electric shearing machine with high safety protection. Background Art

[0002] An electric shearing machine is a processing device used for cutting thin steel plates. The position of a baffle can be adjusted according to processing requirements, and then products with different widths can be cut. When processing, it is driven by a motor, so that a shearing plate and a pressing column descend, and after pressing the steel plate, shearing is performed. However, the existing electric shearing machine has the following deficiencies when in use:

[0003] 1. The pressing mechanism is directly exposed on the outside, lacking a protection mechanism, and there are potential safety hazards during use.

[0004] 2. The baffle will rise and fall together with the shearing plate, and the baffle will rub against the edge of the steel plate, causing wear and affecting product quality.

[0005] Therefore, we propose an electric shearing machine with high safety protection. Content of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies in the prior art that the pressing mechanism is directly exposed on the outside, lacking a protection mechanism, and there are potential safety hazards during use, and the baffle will rise and fall together with the shearing plate, and the baffle will rub against the edge of the steel plate, causing wear and affecting product quality, and to propose an electric shearing machine with high safety protection.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] An electric shearing machine with high safety protection, comprising:

[0009] A frame, on the surface of which a protective cover is fixedly provided. There is a notch at the bottom of the protective cover, and a protective plate is provided on one side of the notch. Two side plates are fixedly provided on one side of the frame, and fixing plates are fixedly provided on one side of each side plate. Inclined guiding grooves are formed on one side of each fixing plate;

[0010] A shearing plate, which is arranged between the two side plates. A connecting frame is fixedly provided at the bottom of the shearing plate. Two sliders are slidably connected to one side of the connecting frame. Adjusting rods are slidably penetrated through one side of each slider. A baffle is fixedly provided at one end of each adjusting rod. Thumbscrews are threadedly penetrated through the surfaces of the sliders, and the thumbscrews are in contact with the adjusting rods. A guiding rod is fixedly penetrated through between the two sliders, and the two ends of the guiding rod are respectively movably connected to the two guiding grooves;

[0011] Two driving mechanisms, both of which are arranged on one side of the frame and are used to drive the shearing plate to rise and fall;

[0012] The pressing mechanism is arranged on one side of the shear plate and is used to press the steel plate.

[0013] In a possible design, the driving mechanism includes a guide rail and a motor. The guide rail is fixedly arranged on one side of the side plate. A lifting plate is slidably connected in the guide rail. The lifting plate is fixed to the shear plate. The motor is fixedly arranged on one side of the frame. One end of the output shaft of the motor is fixedly provided with a turntable. One side of the turntable is rotatably connected with an eccentrically arranged connecting rod. The connecting rod is rotatably connected with the lifting plate.

[0014] In a possible design, the pressing mechanism includes two fixing blocks and two fixing columns. The two fixing blocks are both fixedly arranged on one side of the shear plate. The two fixing columns are both fixedly arranged on the surface of the frame. The two fixing blocks are respectively slidably connected with the two fixing columns. The same pressing plate is slidably connected between the two fixing columns. A plurality of pressing columns are fixedly arranged at the bottom of the pressing plate. A spring is fixedly arranged between the pressing plate and the fixing block. The spring is sleeved on the outer wall of the fixing column.

[0015] In a possible design, two rows of inclined clamping blocks are fixedly arranged on one side of the protective cover. A plurality of inclined clamping grooves are respectively formed on both sides of the protection plate. The clamping blocks are matched with the clamping grooves.

[0016] In a possible design, two inclined guiding plates are fixedly arranged on the surface of the frame.

[0017] In a possible design, a blanking plate is fixedly arranged on one side of the frame. The blanking plate is located between the two side plates.

[0018] In this application, during use, first adjust the position of the protection plate according to the thickness of the steel plate. During adjustment, make the clamping groove dock with the appropriate clamping block. Then adjust the position of the baffle. During adjustment, rotate the setscrew to release the limit on the adjusting rod, then move the adjusting rod to the appropriate position, and then rotate the setscrew again to limit the adjusting rod. Then place the steel plate on the frame, then push the steel plate through the protective cover and against the baffle. Then start the motor. The motor drives the turntable to rotate. The turntable drives the connecting rod to rotate, which in turn drives the lifting plate to descend. The lifting plate drives the shear plate to descend. The shear plate drives the connecting frame to move, which in turn drives the sliding plate, the adjusting rod, the baffle, and the guiding rod to descend. Under the action of the guiding groove, the guiding rod drives the slider to move, so that the baffle moves away from the steel plate to avoid friction. At the same time, the shear plate drives the fixing block to descend, which in turn drives the spring, the pressing plate, and the pressing column to descend. When the pressing column presses the steel plate, the fixing block continues to descend to compress the spring, so that the pressing column presses the steel plate tightly. Then the shear plate shears the steel plate. When the motor drives the turntable to rotate one circle, the connecting rod drives the lifting plate to reset, which in turn drives the rest of the structure to reset. Then continue to push the steel plate against the baffle for processing.

[0020] In the present utility model, for the electric shearing machine with high safety protection, through the arrangement of multiple structures such as a protective cover, a protective plate, and a clamping block, the pressing mechanism can be covered, leaving only a space for the steel plate to pass through, with high safety, and it can be adjusted according to the thickness of the steel plate;

[0021] In the present utility model, for the electric shearing machine with high safety protection, through the arrangement of multiple structures such as a guide rod, a guide groove, and a slider, during processing, when the shearing plate descends, the linkage between the structures can drive the baffle away from the steel plate, avoiding friction and wear with the steel plate and preventing the impact on product quality;
