The utility model provides a novel steel plate punching and shearing machine, firstly, the punching and shearing machine is only suitable for sectional materials with L-shaped sections; then when in use, firstly the section bar needs to be placed in the top of the support frame 4, and after the section bar is positioned in the top opening of the support frame 4, both sides of the section bar are butted on the two groups of supporting rollers 5, then when punching and shearing are carried out by workers, the section bar only needs to be pushed to move towards the punching and shearing hole 3, at the moment, the section bar can directly transit from the supporting rollers 5 into the punching and shearing hole 3, and then the punching and shearing plate of the punching and shearing machine moves downwards or obliquely, so that the section bar is sheared. And after the profile is sheared, the punching shear plate resets, and a worker can push the profile again to move, so that the previous process is carried out until all the profiles are punched and sheared.

When the section bar is pushed, the section bar can directly enter the punching shear hole 3 along the top of the support frame 4 without being aligned by workers, so that the operation convenience is higher, and the workers do not need to hold the section bar in the punching shear plate punching shear and resetting processes, so that the processing strength can be further reduced; meanwhile, in the process of pushing the section bar, workers do not need to bear the weight of the section bar, but only need to overcome the friction force between the section bar and the support frame 4 (the support roller 5), and the method is simple and convenient.

The lengths of the three cross frames 4a in the support frame 4 are equal, but certain differences exist in height and shape, specifically, the cross frames 4a on the two sides are as high as each other, but are all higher than the cross frame 4a in the middle, but the top of the cross frame 4a in the middle is provided with the abdicating groove 6, so that when the L-shaped (or V-shaped) section moves on the support frame 4, the bottom of the section can have a larger distance with the top of the cross frame 4a in the middle (due to the abdicating groove 6), thereby preventing the section from being worn with the cross frame 4a in the middle, prolonging the service life of the equipment, and simultaneously reducing the moving resistance of the section. At the same time, the diameter of the supporting rollers 5 is increased, i.e. the supporting rollers protrude outside the cross-frames 4a on both sides, so that the profile does not contact the cross-frames 4a during the entire movement process.

Secondly, each cross support frame 4a is provided with a plurality of vertical support frames 4b, but the length and the shape of the vertical support frames 4b are different, specifically, the length of the vertical support frame 4b connected with the cross support frame 4a in the middle part is shorter, so that the bottoms of all the vertical support frames 4b can be supported on the ground or a processing field; meanwhile, the vertical support frame 4b at the edge is provided with a first matching hole 9 for matching with a positioning screw rod 10. A plurality of strengthening rods 4c are arranged between the cross frames 4a at the two sides and the cross frame 4a at the middle part, so that the connection stability between the cross frames 4a can be improved, the strength and the stability of the whole support frame 4 frame body structure are improved, and the burden of the connection structure between the support roller 5 and the cross frames 4a is reduced. Wherein the diameter of the consolidation rod 4c is smaller or the position thereof intersects, which does not interact with the profile (preferably the projection of the consolidation rod 4c on the supporting plate 2 is located in the projection of the two groups of supporting rollers 5 on the supporting plate 2).

Wherein, because different section bars have different lengths, if the section bars are shorter, the supporting frame 4 can normally support, but if the section bars are longer, a plurality of adjusting frames 7 are needed to adjust the length of the supporting frame 4; specifically, the adjusting frame 7 is moved to the end of the supporting frame 4, the positioning screws 10 pass through the first matching holes 9, then the positioning nuts are connected to all the positioning screws 10 in a threaded manner, and the adjusting frame 7 and the supporting frame 4 are fixedly connected through the positioning nuts and the positioning screws 10; the shape of the top of the adjusting frame 7 is the same as that of the top of the supporting frame 4, so that the adjusting frame and the supporting frame can be well spliced, and the profile can be well transited and supported; i.e. the profile can pass directly from the regulating roller 8 to the support roller 5.

Moreover, if the length of the whole supporting track needs to be increased, a new adjusting frame 7 can be fixed on the adjusting frame 7 continuously, namely the positioning screw 10 on the new adjusting frame 7 passes through the second matching hole 11 on the adjusting frame 7 at the end part, so that different lengths can be selected according to actual conditions, and the application range is wider.

Meanwhile, it should be understood that the internal structure of the punching and shearing machine (i.e. the main body 1) (including the punching and shearing plate, the power for driving the punching and shearing plate to move, such as a powerful cylinder or a linear motor, and the guide rails for guiding the punching and shearing plate, such as two L-shaped rails on both sides of the punching and shearing plate, etc.) is the same as that of the punching and shearing machine in the market, so that the understanding and implementation of the structure or the scheme actually claimed by the present application are not affected by those skilled in the art even if not described or illustrated; meanwhile, the structure of the punching and shearing machine can be suitable for punching and shearing machines of all models.

It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
