Description

Technical Field

[0001] The present application relates to the technical field of clamps, and more specifically, to a feeding clamp for a shearing machine. Background Art

[0002] The shearing machine cuts metal components with a shearing knife, and generally uses a clamp to clamp the metal component during shearing.

[0003] In the related technology, the clamping and fixing effect is achieved by moving the diagonal steel between the clamping plates. For example, the patent with the prior art publication number CN218694312U provides a shearing machine fixing clamp. When adjusting the spacing between the fixed clamping plate and the movable clamping plate, the device first pulls the toggle plate upward to drive the movable block to slide up in the built-in groove, so that the meshing connection of the latch teeth between the movable block and the adjustment groove is released. At this time, the fixation of the adjustment seat is released and it can slide inside the adjustment groove, thereby adjusting the spacing between the fixed clamping plate and the movable clamping plate.

[0004] Although the above-mentioned prior art solution can achieve the effect of clamping and fixing the metal component by setting the fixed clamp and the movable clamp, it still has the following defects: the metal component is not easy to move for a second shearing after being sheared once, the shearing machine cannot be automatically fed, and the staff is required to manually unlock the clamp and then move the metal component, which reduces the shearing efficiency.

[0005] In view of this, we propose a feeding fixture for a shearing machine. Utility Model Content

[0032] The driving mechanism 3 is arranged at the top and both sides of the clamping mechanism 2, and is used to clamp and fix the metal component body 4.

[0033] After a shearing operation, the hydraulic cylinder 101 can drive the hydraulic rod 102 to extend and retract to push the metal component body 4 to move, thereby performing the next shearing operation and improving the shearing efficiency.

Then, the hydraulic rod 102 is extended or shortened by the hydraulic cylinder 101, driving the metal component body 4 to move, thereby achieving the effect of automatic feeding.

[0036] Reference Figure 1 and Figure 2 The clamping mechanism 2 includes a clamping frame 201, a stabilizing slide bar 202 is symmetrically fixedly arranged on the inner side of the clamping frame 201, a movable clamping plate 204 is slidably arranged on the outer side of the stabilizing slide bar 202, a pad 205 is fixedly arranged on the side where the movable clamping plates 204 are close to each other, a notch is provided on the side where the movable clamping plates 204 and the pad 205 are close to each other, an extension plate 2042 is provided on the side where the movable clamping plates 204 are close to each other, and a sliding groove 2041 is symmetrically provided on the inner side of the movable clamping plates 204.

[0037] When the movable clamping plates 204 move closer to or farther from each other, they will slide on the outside of the stabilizing slide bar 202 to stabilize the movement of the movable clamping plates 204. The setting of the extension plate 2042 can support the metal component body 4 during clamping, making it easier to clamp the metal component body 4.

[0038] Reference Figure 1 , Figure 2 and Figure 3A toothed plate 107 is fixedly provided on one side of the receiving plate 103, a sliding platform 203 is slidably provided on the outer side of the toothed plate 107, the sliding platform 203 is fixedly provided on the top of the clamping stand 201, the driving mechanism 3 includes a double-threaded screw 301, and the outer sides of both ends of the double-threaded screw 301 are respectively provided with a first one-way bearing 302 and a second one-way bearing 303, the double-threaded screw 301 is fixedly provided on the inner rings of the first one-way bearing 302 and the second one-way bearing 303, and the outer rings of the first one-way bearing 302 and the second one-way bearing 303 are respectively fixedly provided with a second sleeve 306 and a first sleeve 304 A driving motor 305 is provided at one end of the first sleeve 304, and the first sleeve 304 is fixedly arranged at the output end of the driving motor 305.

The auxiliary gear 307 is meshed and arranged at the bottom end of the gear plate 107. The double-thread screw 301 passes through and is rotatably arranged on the other side of the clamping frame 201. The clamping frame 201 is fixedly arranged on the top end of the receiving frame 108, and the driving motor 305 is fixedly arranged on one side of the receiving frame 108 through a motor bracket.

[0039] The hydraulic rod 102 is shortened by the hydraulic cylinder 101, so that the connecting plate 106 drives the pre-clamping plate 105 and the pre-clamped metal component body 4 to move, and at the same time, the toothed plate 107 is driven by the connecting plate 106 to move, driving the auxiliary gear 307 in the driving mechanism 3 to rotate, so that the auxiliary gear 307 drives the second sleeve 306, the first one-way bearing 302 and the double-thread screw 301 to rotate, and the double-thread screw 301 rotates in the opposite direction, so that the movable clamping plates 204 move away from each other, and due to the setting of the second one-way bearing 303, the first sleeve 304 does not rotate, thereby loosening the metal component body 4, so that the metal component body 4 can move, and after moving into position, the driving motor 305 is driven to make the double-thread screw 301 rotate forward, so that the movable clamping plates 204 move closer to each other, and clamp the metal component body 4 to achieve the effect of automatic feeding.

[0040] Reference Figure 2 and Figure 4 An auxiliary moving assembly 5 is arranged on the inner side of the notch, and the auxiliary moving assembly 5 includes a moving wheel 501, and the moving wheel 501 is arranged on the inner side of the notch, and sliders 502 are rotatably arranged at both ends of the moving wheel 501, and the sliders 502 are slidably arranged on the inner side of the slide groove, and a pressing spring 503 is fixedly arranged on one side of the slider 502, and the pressing spring 503 is fixedly arranged on the inner side of the slide groove.

[0041] When the metal component body 4 is released by the clamping mechanism 2 , the moving wheel 501 in the auxiliary moving assembly 5 slowly pops out from the notch of the driven clamp plate 204 due to the elastic force of the squeezing spring 503 , and fits with the metal component body 4 , facilitating the movement of the metal component body 4 .

[0042] Working principle: put the metal component body 4 between the pads 205, then start the electric telescopic rod 104 to press the pre-clamp 105 downward, the pre-clamp 105 cooperates with the fixed clamp to clamp one end of the metal component body 4, then start the driving motor 305 in the driving mechanism 3, the driving motor 305 drives the first sleeve 304 and the second one-way bearing 303 to rotate, the rotation of the second one-way bearing 303 drives the double-thread screw 301 to rotate, the rotation of the double-thread screw 301 drives the movable clamp 204 in the clamping mechanism 2 to approach each other, so that the pad 205 clamps the metal component body 4, and the shearing machine then shears the other end of the metal component body 4. When continuing to shear the metal component body 4, the hydraulic cylinder 101 drives the hydraulic rod 102 to shorten, so that the connecting plate 106 drives the pre-clamp 105 and the pre-clamped metal component body 4 to move, and at the same time the tooth plate 10 7 will be driven by the connecting plate 106 to move, driving the auxiliary gear 307 in the driving mechanism 3 to rotate, so that the auxiliary gear 307 drives the second sleeve 306, the first one-way bearing 302 and the double-thread screw 301 to rotate, and the double-thread screw 301 rotates in the opposite direction, so that the movable clamping plates 204 move away from each other, and due to the setting of the second one-way bearing 303, the first sleeve 304 will not rotate, thereby loosening the metal component body 4, so that the metal component body 4 can move. At this time, the moving wheel 501 in the auxiliary moving component 5 slowly pops out from the notch of the movable clamping plate 204 due to the elastic force of the extrusion spring 503, and fits with the metal component body 4, which is convenient for the movement of the metal component body 4. After moving into place, the driving motor 305 is driven to make the double-thread screw 301 rotate forward, thereby making the movable clamping plates 204 approach each other, and clamping and fixing the metal component body 4, thereby achieving the effect of automatic feeding.
