Technical Field

[0001] The utility model relates to a numerically controlled gate-type plate shearing device, belonging to the technical field of plate shearing machines. Background Art

[0002] Shearing machine is a machine that shears plates by reciprocating linear motion of one blade relative to another blade. It applies shearing force to metal plates of various thicknesses by using a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap, so that the plates are broken and separated according to the required size; CNC shearing machine refers to a technical machine that realizes the motion control of one or more shearing machines through digital instructions composed of numbers, words and symbols, and is controlled by digital programs by computers.

[0003] When the CNC shearing machine is processing the plate, it is unable to limit the plate. During the shearing process, the plate may warp up. When cutting curved or wrinkled metal sheets, it is easy to warp the edge, which will cause the side of the plate to be uneven, thus affecting the processing accuracy. Utility Model Content

The top end of the movable rod passes through the movable plate, the bottom end of the movable rod passes through the limiting cylinders and is connected to a fixing member.

[0013] The beneficial effects of the utility model are:

[0014] Through the setting of the stabilizing mechanism, when the stabilizing mechanism is in operation, it will drive the stabilizing plate and the protective net to move at the same time. The stabilizing plate moves down and contacts the surface of the plate, so as to fix the plate, thereby achieving the purpose of limiting. The protective net moves down to adjust the distance between the shearing cavity and the plate according to the height of the plate, isolate the staff from the shearing cavity, and avoid injuries to personnel caused by flying debris during the shearing process.

[0015] By coordinating the stabilizing mechanism and the stabilizing plate, the stabilizing plate can be driven downward to contact the surface of the plate, thereby fixing the plate, thereby achieving the purpose of limiting, preventing the plate from warping under the impact force of the shearing tool, ensuring the smooth completion of the shearing action, and improving the shearing quality of the plate.

[0016] Through the setting of the protective net, the protective net is located at the feeding end of the shearing chamber, shielding the workers from the shearing chamber, avoiding injuries to the workers caused by flying debris when shearing the plates, and improving the safety of the shearing machine body.

[0017] Through the coordinated setting of the protective net and the stabilizing mechanism, the protective net also moves with the movement of the stabilizing mechanism. Because the position between the protective net and the stabilizing plate has been fixed with the support plate in advance, when the stabilizing plate comes into contact with the plate, at this time, the distance between the protective net and the bottom of the feed end is just enough for the plate to pass through. Moreover, with the operation of the stabilizing mechanism, the protective net can be driven to adjust according to the height of the plate, thereby avoiding the splashing of debris when shearing the plate with lower thickness, causing injury to the staff, thereby improving the safety of the shearing machine. At the same time, the up and down movement of the protective net can be suitable for the processing of plates of different thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 , Figure 2 The utility model provides a technical solution for a numerically controlled gate-type shearing device, a numerically controlled gate-type shearing device, comprising a shearing machine body 1, a platform 2 is provided on the front of the shearing machine body 1, a shearing cavity is opened in the shearing machine body 1 and at the upper end of the platform 2, a feed end 5 and a discharge end are respectively provided on the front and rear sides of the shearing cavity, a feed chute 3 is provided on the surface of the platform 2, an end of the feed chute 3 corresponds to the feed end 5 of the shearing cavity, a plate is provided on the feed chute 3, and a stabilizing mechanism matching the plate is provided inside the shearing cavity and close to the feed end 5.

[0026] See also Figure 1 , Figure 2 and Figure 3 and Figure 4 The stabilizing mechanism includes a limit rod 8 and a motor 9 fixedly connected at the top of the shearing plate cavity. The output end of the motor 9 is provided with a threaded rod 7. The outer surface of the threaded rod 7 is threadedly connected with a connecting plate 10. The other end of the connecting plate 10 is sleeved on the limit rod 8. A connecting rod 11 is provided at the left and right ends of the connecting plate 10 respectively. The limit rod 8 and the bottom end of the motor 9 are fixedly connected with a fixing plate 6. The left and right ends of the fixing plate 6 are fixedly connected with the inner walls of the two sides of the shearing plate cavity respectively. The bottom ends of the two connecting rods 11 pass through the fixing plate 6 and are connected to a moving plate 12. The bottom end of the movable plate 12 is provided with two limiting cylinders 13, and a movable rod 14 is movably connected inside the limiting cylinder 13. The top end of the movable rod 14 passes through the outside of the movable plate 12, and the bottom end of the movable rod 14 passes through the outside of the limiting cylinder 13 and is connected to a fixing member 16. The bottom end of the fixing member 16 is connected to a support plate 17. The outer surface of the movable rod 14 is sleeved with a spring 15, and the spring 15 is located between the limiting cylinder 13 and the fixing member 16. The top end of the spring 15 is pressed against the bottom end of the limiting cylinder 13, and the bottom end of the spring 15 is pressed against the top end of the fixing member 16. Through the setting of the stabilizing mechanism, the stabilizing plate 19 can be driven to move downward to contact the surface of the plate, and then the plate can be fixed, so as to achieve the purpose of limiting, prevent the plate from warping under the impact force of the shearing tool, ensure the smooth completion of the shearing action, and thus improve the shearing quality of the plate.

[0027] See also Figure 1 Figure 2 and Figure 3 The bottom end of the support plate 17 is provided with a protective net 4, and a plurality of stabilizing rods 18 are provided on both sides of the bottom end of the protective net 4. The bottom end of the stabilizing rod 18 is provided with a stabilizing plate 19, and the bottom ends of the protective net 4 and the stabilizing plate 19 penetrate into the feeding end 5, and the bottom end of the stabilizing plate 19 contacts the top of the plate. Through the cooperation of the protective net 4 and the stabilizing mechanism, the protective net 4 also moves with the movement of the stabilizing mechanism. Due to the position between the protective net 4 and the stabilizing plate 19 and the prior fixation with the support plate 17, when the stabilizing plate 19 contacts the plate, at this time, the distance between the protective net 4 and the bottom end of the feeding end 5 is just enough for the plate to pass through, and with the operation of the stabilizing mechanism, the protective net 4 can be driven to adjust according to the height of the plate, thereby avoiding the situation where debris splashes out when shearing a plate with a lower thickness, causing injuries to the staff, thereby improving the safety of the shearing machine. At the same time, the up and down movement of the protective net 4 can be suitable for the processing of plates of different thicknesses.

[0028] See also Figure 2 and Figure 3 and Figure 4 The surface of the fixed plate 6 is provided with two movable holes 1 that cooperate with the connecting rod 11, the movable plate 12 is provided with two movable holes 2 that cooperate with the movable rod 14, and a control box is provided on one side of the top of the shearing machine body 1, and the motor 9 is electrically connected to the control box.

[0029] When in use, first place the sheet on the surface of the feed slide 3. With the assistance of the feed slide 3, the sheet enters the interior of the shearing cavity from the front of the platform 2. When the sheet enters the interior of the shearing cavity, the sheet may deviate during the process of driving the sheet forward. At this time, the staff can make appropriate adjustments to the position of the sheet according to the actual situation of the sheet entering. Subsequently, the stabilizing plate 19 in the stabilizing mechanism can be started to fix the sheet. The motor 9 is started by controlling the external switch. The rotation of the motor 9 drives the threaded rod 7 to rotate. Under the limit of the limit rod 8, the threaded rod 7 rotates and drives the connecting plate 10 to move up and down along the length direction of the threaded rod 7. The connecting plate 10 drives the connecting rod 1 1. The movable plate 12 moves, and the movable plate 12 drives the limiting cylinder 13, the spring 15 and the fixing part 16 to move. The fixing part 16 moves and drives the supporting plate 17 and the stabilizing rod 18 and the stabilizing plate 19 at the bottom of the supporting plate 17 to move up and down. The stabilizing plate 19 moves downward until it contacts the surface of the plate, and then the plate can be fixed, thereby achieving the purpose of limiting, preventing the plate from warping under the impact force of the shearing tool, ensuring the smooth completion of the shearing action, thereby improving the shearing quality of the plate, and then starting the shearing machine body 1 to shear the plate (the shearing machine body 1 in this application is a prior art, so it is not described in detail here).

[0030] At the same time, the protective net 4 also moves with the movement of the stabilizing mechanism. Because the position between the protective net 4 and the stabilizing plate 19 and the prior fixation with the support plate 17 are achieved, when the stabilizing plate 19 comes into contact with the plate, at this time, the distance between the protective net 4 and the bottom of the feed end 5 is just enough for the plate to pass through. Moreover, with the operation of the stabilizing mechanism, the protective net 4 can be driven to adjust according to the height of the plate, thereby avoiding the situation where debris splashes out of the shearing machine body 1 when shearing plates with lower thickness, causing injuries to the staff, thereby improving the safety of the shearing machine body 1.

[0031] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
