Description

TECHNICAL FIELD

[0001] The utility model relates to cold shears cutting edge technical field, concretely relates to a kind of adjusting cutting edge spacing device for cold shears. BACKGROUND

[0002] Cold shears, also known as cold shearing machine, is a heavy machinery for shearing rolled piece at room temperature, which is widely used in metal processing, scrap metal recycling and building material processing and other fields. The composition of cold shears mainly includes the following core parts: power transmission system, shearing execution mechanism, control system and auxiliary system, etc. The shearing execution mechanism mainly includes clutch and shearing body. The shearing body refers to the component assembled with cutting edge. The shearing body is divided into upper shearing body and lower shearing body. The upper shearing body is movably connected with the cold shears frame. In order to increase the service life of the cold shears frame, a sliding plate is detachably connected between the upper shearing body and the cold shears frame. The lower shearing body is fixed on the cold shears frame and located directly below the upper shearing body. The upper cutting edge is installed on the upper shearing body, and the lower cutting edge is installed on the lower shearing body. The upper cutting edge moves up and down linearly to shear the rolled piece. Since the upper shearing body is movably connected with the sliding plate, the shearing edge and the rolled piece interact at the moment when the shearing edge contacts the rolled piece for shearing, which causes the wear of the sliding plate and the increase of the horizontal distance between the upper cutting edge and the lower cutting edge. In the subsequent shearing work, since the upper cutting edge is not perpendicular to the lower cutting edge, it causes the problems of non-perpendicularity of the cut surface of the rolled piece, excessive bend of the rolled piece and burr.

[0017] Example

[0018] like Figures 1 to 4 As shown: A device for adjusting the blade spacing of a cold shear machine includes a support block 1, a wedge 1 2, and a wedge 2 3. The support block 1 is bolted to a cold shear machine frame 13. The wedge 1 2 is slidably connected to the support block 1. A screw 8 is fixedly connected to the wedge 1 2, and the screw 8 movably passes through the cold shear machine frame 13. A limit block 6 is fixedly connected to the screw 8, located above the wedge 1 2 and below the cold shear machine frame 13. A handwheel 7 is threadedly connected to the screw 8, and the handwheel 7 is rotatably connected to the cold shear machine frame 13. The wedge 2 3 is slidably connected to the wedge 1 2. The cold shear machine frame 13 and the support block 1... Both the first and second inclined irons are provided with strip-shaped through holes 12, which are divided into three sections. Each section of the strip-shaped through hole 12 has a bolt 9 that moves through it. The bolt 9 is threadedly connected to the second inclined iron 3. The second inclined iron 3 is bolted with a sliding plate 4. The sliding plate 4 is made of copper alloy, model: ZCuA19Fe4Ni4Mn2. The sliding plate 4 is slidably connected to the upper shear body 5. The free end of the bolt 9 is fixed with a handle 10. Each handle 10 is a ring handle. The handle 10 abuts against the cold shear frame 13. The support block 1, the first inclined iron 2, the second inclined iron 3 and the sliding plate 4 are all the same length as the upper shear body 5.

[0019] The implementation method of this embodiment is as follows: When the upper shear body 5 is offset due to wear of the slide plate 4, and it is necessary to reduce the lateral distance between the upper and lower shear blades, first loosen the bolt 9, then turn the handwheel 7 to move the screw 8 upward, causing the wedge 1 2 to move upward relative to the support block 1, thereby causing the wedge 2 3 to move to the right relative to the support block 1. At this time, the lateral distance between the upper and lower shear blades is reduced. The bolt 9 moves with the wedge 2 3 in the strip-shaped through hole 12. When the upper and lower shear blades are perpendicular, then stop turning the handwheel 7, and finally tighten the bolt 9 and the wedge 2 3. At this time, the handle 10 abuts against the cold shear frame 13, so that the support block 1 and the wedge 1 2 are fixed. When the slide plate 4 is excessively worn and needs to be replaced, increase the lateral distance between the upper and lower shear blades. First, move the screw 8 downward through the handwheel 7, thereby causing the wedge 2 3 to move to the left relative to the support block 1, thereby increasing the lateral distance between the upper and lower shear blades.

[0020] The above is only the embodiment of the present application, and the well-known specific structure and characteristics and other common knowledge in the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
