Description

Bar wire rough rolling back crop device

Technical Field

The utility model relates to a steel rolling production technical field specifically is a rod line rolls back crop device roughly.

Background

At present, in steel rolling production, the head of a bar is extruded and deformed in the rolling process after the bar is rolled by a roughing mill, so that the head is easily split and cracks are generated, therefore, the head of a red steel bar needs to be cut before the bar is subjected to finish rolling, the cutting is a process requirement for ensuring normal operation of production, and according to the process requirement, the red steel bar after roughing needs to be cut by a fixed oblique hydraulic shear to ensure that the split and the cracks are completely removed, so that the surface quality is ensured.

The existing method for cutting the bar by adopting manual head cutting has the following defects: 1. the end surface quality of the bar after manual end cutting is not high, the ends of the bar after end cutting are uneven and sometimes contain slag, and the quality of the bar can be influenced in the subsequent rolling process; 2. the cutting head of the acetylene cutter is too dangerous, so that safety accidents are easy to happen; 3. the temperature of the manual crop rod is too high, and the influence on the health of workers is too large.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problems of low efficiency, poor quality and high risk of a traditional bar material adopting a manual head cutting mode are solved.

The utility model provides a crop device behind rod line rough rolling, including the last cutting edge and the lower cutting edge that are relative arrangement from top to bottom, it is fixed to go up the cutting edge, the cutting edge passes through first oil cylinder drive down, and 45-50 jiaos are personally submitted with the level to its traffic direction.

The utility model replaces manual operation, realizes the automation of bar head cutting, has high efficiency and quality, and reduces the danger; the setting of lower shear blade traffic direction makes first hydro-cylinder keep away from being cut red hot rod, and the cinder that peels off during the shearing can not drop on first hydro-cylinder, even take place hydraulic oil and leak, can not cause major accident yet, guarantees equipment safety.

Further, the rod wire rough rolling back crop device also comprises a base, wherein the upper end of the base forms an angle of 45-50 degrees with the horizontal plane, the upper end of the base is provided with a rack, and the first oil cylinder, the upper shear blade and the lower shear blade are arranged on the rack. The running direction of the lower shear blade is realized through the inclined arrangement of the upper end of the base, the structure is simple, and the disassembly and the assembly are convenient.

Furthermore, the two sides of the rack are provided with guide plates which form an L shape and are symmetrically arranged, the guide plates and the rack form guide grooves for installing the two ends of the movable plate of the lower shearing blade are clamped with the guide grooves, and the lower shearing blade is movably guided. So set up, simple structure, processing is convenient.

Furthermore, a second oil cylinder for driving the rack to lift is further arranged at the upper end of the base. When the utility model discloses during out-of-work, second hydro-cylinder drive frame rises, makes the cutting edge be located non-shearing position to improve the production security.

Furthermore, the shearing surfaces of the upper shearing edge and the lower shearing edge are L-shaped and form an included angle of 94-98 degrees. So set up, shear blade intensity is higher, and shock resistance is strong, and is not fragile.

Furthermore, a chute which is obliquely arranged is further installed on the base, the chute is located corresponding to the upper shearing edge and located right below the blanking of the cut bar. After the rod material is cut, the cutting material automatically falls into the chute and falls into a collection position along the chute, so that manual operation is avoided, the working efficiency is improved, and the safety is also improved.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in fig. 1, the utility model relates to a crop device after rod line rough rolling, including base 4, 45 jiaos are personally submitted with the level in the 4 upper ends of base, and frame 5 is installed to the 4 upper ends of base, installs first hydro-cylinder 3 in the frame 5, goes up shear blade 1 and shear blade 2 down, goes up shear blade 1 fixed, and lower shear blade 2 is through the drive of first hydro-cylinder 3. The shearing surfaces of the upper shear blade 1 and the lower shear blade 2 are L-shaped and form an included angle of 94 degrees. So set up, shear blade intensity is higher, and shock resistance is strong, and is not fragile. The running direction of the lower shear blade 2 is realized through the inclined arrangement of the upper end of the base 4, the structure is simple, and the disassembly and the assembly are convenient.

Guide plates 51 which form an L shape and are symmetrically arranged are arranged on two sides of the rack 5, the guide plates 51 and the rack 5 form guide grooves, and the guide grooves are used for clamping two ends of a movable plate of the lower shear blade 2 to realize the movable guide of the lower shear blade 2. So set up, simple structure, processing is convenient.

As shown in fig. 2, the upper end of the base 4 is further provided with a second oil cylinder 6 for driving the frame 5 to ascend and descend. When the utility model discloses during out-of-work, 6 drive frames 5 of second hydro-cylinder rise, make the cutting edge be located non-shearing position to improve the production security.

The base 4 is also provided with a chute 7 which is obliquely arranged, and the chute 7 corresponds to the upper shear blade 1 and is positioned right below the blanking after the bar material is cut. After the rod material is cut, the cutting material automatically falls into the chute 7 and falls into a collection position along the chute 7, so that manual operation is avoided, the working efficiency is improved, and the safety is also improved.

The utility model replaces manual operation, realizes the automation of bar head cutting, has high efficiency and quality, and reduces the danger; the setting of 2 traffic directions of lower shear blade makes first hydro-cylinder 3 keep away from being cut red hot rod, and the cinder that peels off during the shearing can not drop on first hydro-cylinder 3, even take place hydraulic oil and leak, can not cause major accident yet, guarantees equipment safety.

Example two: compared with the first embodiment, the differences are as follows: the upper end of the base 4 forms an angle of 50 degrees with the horizontal plane; the shearing surfaces of the upper shear blade 1 and the lower shear blade 2 form an included angle of 98 degrees.
