Description

Cutting equipment for bolt production and processing Technical Field The invention relates to the technical field of cutting devices, in particular to cutting equipment for bolt production and processing. Background The bolt is used as an important mechanical base piece and is widely applied to various mechanical equipment and structures, in the automatic production process of the bolt, cutting and blanking of materials are first key procedures, and the cutting precision directly influences the processing quality of subsequent cold heading, thread rolling and other procedures and the size consistency of a final product. In the bar cutting equipment of current bolt production, especially when adopting disc cutting blade to cut, because the disc cutting blade can exert a pressure when pressing to the material, and the shearing force when cutting, in order to guarantee the stability and the positioning accuracy of material when cutting, can set up centering mechanism in cutting station the place ahead, carry out centering centre gripping spacing to wire rod or bar, in the present scheme, a common mode is that adopts three-jaw anchor clamps to carry out centering fixed to the bar, this type of structure can realize better centering effect, but in the cutting process, need carry out centering fixed to the bar earlier, release the claw dish after the cutting is accomplished again, so that feeding equipment continuously pushes away the bar to the cutting station, then again centering locking is carried out cutting next time, three-jaw anchor clamps need carry out centering locking and release action repeatedly in the use, feeding action and locking action are gone on in turn, be difficult to adapt to continuous cutting requirement under the continuous feeding state, thereby influence whole production beat and cutting efficiency, still can adopt V type piece centering mechanism to be used for cutting cutter front centering mechanism, V type piece centering mechanism is by the setting up by the relative V type of centering mechanism, V type piece centering mechanism is realized by the relative motion of a V type of a relative motion piece, the relative V type of device is realized, the relative V type of the relative motion is realized, the relative V type piece is realized, the relative V type is realized, and the relative cutter is generally has a relative type of the device is used to be realized, and is provided with the relative to the V type is shaped to the type a cutter. The prior V-shaped block type centering mechanism has limited application range and poor adaptability in practical application, particularly, the size and the included angle of the opening of the V-shaped groove of the traditional V-shaped block are usually fixed, the effective centering diameter range is strictly limited in a smaller interval, when production tasks need to be switched among bolt products with different specifications, the original V-shaped block cannot always provide effective centering clamping, even the material is swayed or positioned inaccurately due to the mismatching of the included angle of the opening of the V-shaped groove, particularly, when the diameters of bars needing centering are smaller, the V-shaped blocks are abutted against each other, the bars with relatively smaller diameters cannot be stably contacted, and when the bars with relatively larger diameters are locked in a centering way, the edge of the V-shaped block is in contact with the surface of the bar, but the inclined plane of the V-shaped block is not in contact with the surface of the bar, the contact area of the V-shaped block and the bar is relatively narrow, the stability of centering locking is relatively poor, the bar is easy to separate from the V-shaped block or scratch the surface of the bar when tangential force and vibration force generated by cutting are applied, further, scratches are also generated on the surface of the bar when the bar is conveyed, and therefore, in the existing cutting equipment, continuous feeding and continuous cutting are difficult to be considered, or stable centering locking under bars with multiple specifications is difficult to be considered, further, the problems of insufficient support, inaccurate positioning and surface abrasion are easy to occur to the bar in the cutting process, and the stability and the processing consistency in the cutting process are poor. Disclosure of Invention The invention aims to provide cutting equipment for bolt production and processing, which improves the universality and suitability of centering locking during continuous feeding, further ensures the stability of bars in the cutting process and improves the processing consistency of cutting processing. In order to achieve the above purpose, the invention is realized by the following technical scheme: The cutting equipment for bolt production and processing comprises a cutting tool assembly and a front cutter centering convey
