Description

Technical Field

[0001] The utility model relates to the technical field of shearing machines, in particular to a shearing machine for mold processing which is convenient for positioning a plate. Background Art

[0002] During the mold processing process, the plate substrate needs to be cut and sheared. The shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear the plate. It uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shearing force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. After searching, the patent with the publication number CN118237657B discloses a precision shearing equipment for stainless steel production with an intelligent positioning function. It uses an electric gripper to control the transmission screw and a clamping base to control the movement of the progressive device. By switching the rotation form of the transmission screw and the movement mode of the progressive device, the two functions of the positioning device width adjustment and the progressive device feeding are switched. The progressive device moves on the transmission screw to achieve high-precision control of the steel plate feeding step. At the same time, it can also control the variable adjustment of the next feeding step in real time, so that the shearing equipment can dynamically adjust the feeding step to achieve cutting of multiple lengths of the same steel plate. The positioning device can intelligently adjust the size to match the width of the steel plate, and then drive the pressing device through the guide device to achieve multi-faceted fixation of the side, top and bottom of the steel plate, so that the steel plate will not have position deviation during the feeding process; the lower pressure roller and the side pressure roller not only position the steel plate, but also prevent the surface of the steel plate from being scratched due to movement. However, the way it unloads through the first electric telescopic rod and the bottom support, the electric telescopic cylinder is always under force, which is easy to be damaged over a long period of time, and then the bottom support is prone to tilt relative to it, thereby posing a risk of hindering the plate from sliding over the bottom support. For this reason, a unloading mechanism with high stability is designed, and in the free state, the unloading drive is not under force, which extends the service life of the unloading mechanism and improves the continuous stability of the overall structural processing, thereby facilitating the positioning of the plate for mold processing shearing machines.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figure 1-7 The cam 24 is provided with an L-shaped support plate 1 and an L-shaped support plate 2 is provided on the cam 24 so that the cam 24 can move relative to the workpiece 1. The cam 24 is provided with an L-shaped support plate 1 and an L-shaped support plate 2 is provided on the cam 24 so that the cam 24 can move relative to the workpiece 1.

[0026] Specifically, the unloading drive component includes a U-shaped frame 12 fixedly mounted on the frame 1, and a full gear 14 is rotatably connected to the U-shaped frame 12. An incomplete gear 15 that can mesh with the full gear 14 is fixedly mounted on one end of the rotating shaft 9. A plurality of meshing teeth 16 that are spaced apart and mesh with the full gear 14 are provided on one circumferential side of the incomplete gear 15. It also includes a drive component that drives the full gear 14 to rotate. Starting the drive component facilitates driving the full gear 14 to rotate counterclockwise for one circle, and through meshing with the plurality of meshing teeth 16, the incomplete gear 15 can be driven to rotate clockwise, and the loading drive cylinder 6 can be made to rotate within the angle range of the plurality of meshing teeth 16, thereby completing one unloading operation, and then under the action of the weight of the support plate itself, the support plate is driven to return to a free state. Further, the drive component includes a unloading motor 13 fixedly mounted on the U-shaped frame 12.

[0027] Specifically, the diameter of the incomplete gear 15 is larger than the diameter of the full gear 14. By making the diameter of the incomplete gear 15 larger than the diameter of the full gear 14, the turning speed of the discharge block can be slowed down, the speed can be reduced, and the discharge stability can be improved.

[0028] Specifically, it also includes a feeding slider 3 that slides back and forth with the frame 1. A positioning drive cylinder 5 is fixedly installed on the feeding slider 3 to drive the L-shaped positioning block 4 to move left and right. A feeding drive cylinder 6 is also fixedly installed on the frame 1 to drive the feeding slider 3 to move back and forth. The positioning drive cylinder 5 is used to drive the L-shaped positioning block 4 to position one side of the plate. The two L-shaped positioning blocks 4 are used to facilitate positioning of the plate. The feeding drive cylinder 6 is used to facilitate driving the feeding slider 3 to slide back and forth, thereby facilitating loading.

[0029] Specifically, a guide mechanism is provided on the frame 1 on the side of the positioning and pushing mechanism. The guide mechanism includes a groove opened on the frame 1, and a plurality of guide rollers 7 are connected to the groove at intervals and rotated. The top of the guide roller 7 is flush with the top of the frame 1, and an elastic friction roller sleeve 8 is fixed on the guide roller 7. Through the guide mechanism, it is convenient to guide the plate during loading, reducing the difficulty of loading and reducing the friction between the plate and the frame 1. By setting the elastic friction roller sleeve 8, the friction between the guide roller 7 and the plate is increased, and the stability of the guide is further guaranteed. At the same time, the elastic friction roller sleeve 8 can be compressed.

[0030] Specifically, shielding curtains 17 are provided at both entrances and exits, and the provision of the shielding curtains 17 facilitates dust prevention.
