Description

Technical Field

[0001] The utility model relates to the technical field of machining, and more specifically, to a shearing machine for machining. Background Art

[0002] A shearing machine is a common sheet metal shearing device. The shearing machine applies a shearing force to metal sheets of various thicknesses by means of a moving blade moving reciprocally linearly relative to a fixed blade, causing the sheet metal to break and separate according to the required dimensions.

[0003] Existing shearing machines include a frame and a loading platform for supporting the metal sheet to be cut. There is a cutting opening between the frame and the loading platform. A cutting plate is provided at one side of the loading platform at the cutting opening. A fixed blade is provided on the side of the cutting plate away from the loading platform. A moving blade is provided on the side of the frame close to the cutting plate. A spring pressing foot is provided on one side of the frame. The spring pressing foot is located above the cutting plate. When the shearing machine cuts metal sheets, the operator places the metal sheet to be cut on the loading platform and pushes it into the cutting plate through the cutting opening. The operator adjusts the position of the metal sheet so that the area to be cut on the metal sheet is located between the fixed blade and the moving blade. Subsequently, the spring pressing foot presses the metal sheet onto the cutting plate, and the moving blade moves towards the fixed blade and applies a shearing force to the metal sheet to complete the cutting of the metal sheet.

[0004] However, before being positioned by the spring pressing foot, the metal sheet mainly relies on manual assistance for positioning. Workers need to continuously adjust the position to make the sheet enter the cutting opening in a horizontal posture. During this process, since the sheets generally have a certain mass, it is very labor-consuming for workers when moving, and the metal sheets are prone to displacement.

[0005] Therefore, there is an urgent need to develop a solution for a shearing machine that can solve the above problems and save workers' physical strength. Summary of the Invention

[0006] The technical problem to be solved by the utility model is that before being positioned by the spring pressing foot, the metal sheet mainly relies on manual assistance for positioning. Workers need to continuously adjust the position to make the sheet enter the cutting opening in a horizontal posture.

[0028] As Figures 1 to 3 and Figure 5 shown, the shearing machine for machining includes: a frame 1 and a loading table 2.

[0029] A shearing opening 3 is provided between the frame 1 and the loading table 2. A spring pressing foot 4 and a blade 5 are installed on the frame 1. Two limiting seats 6 are symmetrically fixed on the loading table 2, and a plurality of support rollers 7 are arranged at intervals between the two limiting seats 6.

[0030] The support rollers 7 are movably arranged between the two limiting seats 6 through bearings. A transmission shaft 13 is fixed on each of the plurality of support rollers 7. A belt pulley 14 is installed on the transmission shaft 13. Adjacent belt pulleys 14 are connected by a belt. A motor 15 is installed on the loading table 2, and the output end of the motor 15 is installed on one side of the belt pulley 14.

[0031] Adjacent transmission shafts 13 are connected by a belt to the belt pulley 14. When one of the transmission shafts 13 rotates, the rest of the transmission shafts 13 all rotate in the same direction, driving the plate to be sheared to move towards the shearing opening 3.

[0032] According to one or some embodiments of the present utility model, a receiving cavity 8 is formed on the surface of the loading table 2. A plurality of moving seats 9 are arranged at intervals inside the receiving cavity 8. A limiting component is arranged on one side of the moving seat 9. A guide rail 10 is fixed inside the receiving cavity 8. The guide rail 10 penetrates through the moving seat 9 and is slidably connected to the moving seat 9.

[0033] According to one or some embodiments of the present utility model, a plurality of card slots 11 are formed at intervals on the surface of the moving seat 9. A limiting rod 12 is arranged between adjacent support rollers 7, and the bottom of the limiting rod 12 is engaged with the card slot 11.

[0034] According to one or some embodiments of the present utility model, the limit assembly includes a support base 16, a first stop post 17 and a second stop post 18. The support base 16 is installed on the moving base 9. A sliding post 19 is penetrated through the support base 16. A pressing plate 20 is installed on the top of the sliding post 19. The bottom of the sliding post 19 is fixedly connected with the first stop post.

[0035] According to one or some embodiments of the present utility model, a plurality of pairs of second stoppers 18 are fixedly spaced on one side of the loading platform 2, and the first stop post 17 is located between the two second stoppers 18.

[0036] According to one or some embodiments of the present utility model, a return spring 21 is sleeved on the sliding post 19. One end of the return spring 21 is fixed on the support base 16, and the other end of the return spring 21 is fixed on the pressing plate 20.

[0037] According to one or some embodiments of the present utility model, the distance between the two second stoppers 18 is the same as the diameter of the first stop post.

[0038] According to one or some embodiments of the present utility model, the length of the first stop post is greater than that of the second stopper 18.

[0039] The staff can adjust the position of the moving base 9 according to the size of the metal plate. The specific adjustment method is to press the pressing plate 20 to drive the sliding post 19 and the first stop post 17 to move downward, so that the first stop post 17 disengages from between the two second stoppers 18. At this time, the position of the moving base 9 can be adjusted along the guide rail 10. After the adjustment is completed, release the pressing plate 20. Under the action of the return spring 21, the first stop post 17 can enter between the two second stoppers 18 again. At this time, the fixation of the position of the moving base 9 can be completed, and the operation is simple and convenient.

[0040] Figure 4 It is a schematic diagram showing the support frame 23 according to an embodiment of the present utility model.

[0041] According to one or some embodiments of the present utility model, two mounting plates 22 are symmetrically fixed on one side of the frame 1. The support frame 23 as shown is installed between the two mounting plates 22 through bolts. Figure 4 A transparent plate 24 is installed on the support frame 23.

[0042] According to one or some embodiments of the present utility model, the transparent plate 24 is made of acrylic material.

[0043] A certain gap is left between the bottom of the support frame 23 and the carrier table 2 so that the sheet can enter the inside of the cutting opening 3. By providing the transparent plate 24, on the one hand, it can prevent the worker's fingers from entering the inside of the cutting opening 3, and on the other hand, due to its transparency, it does not affect the staff's observation of the internal condition of the cutting opening 3. The transparent plate 24 is made of acrylic material, which is easy to process and has a high transparency.

[0044] When the present utility model is in use, the staff only needs to adjust the position of the moving seat 9 according to the size of the metal sheet. After the adjustment is completed, the corresponding limiting rod 12 is inserted into the clamping groove 11. During feeding, the sheet is directly placed between the adjacent limiting rods 12, ensuring that the posture of the sheet entering the cutting opening 3 will not shift; by starting the motor 15 to drive the rotation of a plurality of support rollers 7, the sheet can be driven to move towards the cutting opening 3, greatly saving the physical strength of the staff.

[0045] The above description is only an exemplary embodiment of the present utility model and is not used to limit the protection scope of the present utility model. The protection scope of the present utility model is determined by the appended claims.
