Description

Technical Field

[0001] The utility model belongs to the field of mechanical processing, and more specifically, relates to a tool holder structure for roller processing. The utility model also relates to a roller production line, which is provided with the tool holder structure for roller processing. Background Art

[0002] Steel rolling is the process of changing the shape of steel ingots and billets between rotating rollers. The purpose of steel rolling is the same as other pressure processes. On the one hand, it is to obtain the required shape, such as steel plates, strips, wires and various steel sections; on the other hand, it is to improve the internal quality of steel.

[0003] The billets coming out of the steel mill are only semi-finished products. They must be rolled in the steel rolling mill before they can become qualified products. The continuous casting billets sent from the steel mill first enter the heating furnace, and then go through the primary rolling mill for repeated rolling before entering the finishing mill. Steel rolling belongs to metal pressure processing. To put it simply, rolling steel plates is like rolling noodles. After repeated squeezing and pushing by the rolling pin, the noodles become thinner and thinner. On the hot rolling production line, the billets are heated and softened, and then sent into the rolling mill by rollers, and finally rolled into the size required by the user.

[0004] Rollers are the main working parts and tools for continuous plastic deformation of metals on rolling mills. Rollers are mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. The shaft head at the transmission end is connected to the gear seat through the connecting shaft to transmit the rotational torque of the motor to the roll. The rolls can be arranged in the form of two rolls, three rolls, four rolls or multiple rolls in the rolling mill frame.

[0005] Generally speaking, due to the large size of the roller, a specific lathe is required for processing. During the processing of the roller, the existing lathe needs to set a support roller at the bottom of the roller to prevent the roller from falling off the lathe due to insufficient clamping force at both ends. However, during the process of cutting the roller by the turning tool, in order to increase the processing efficiency of the roller, the feed amount of the turning tool is generally set to be relatively large, which leads to a higher load on the turning tool. During the process of processing the roller, the structural strength of the existing turning tool mounting frame cannot meet the requirements, and it is impossible to always maintain sufficient processing accuracy during the long processing process, and it is urgently needed to be improved.

Generally speaking, the utility model mainly supports the cutter by arranging a support structure on the lathe, thereby preventing the cutter from uncontrollably deviating due to insufficient lathe strength during the process of cutting the roller, thereby ensuring the processing accuracy of the cutter on the roller.

[0032] Based on the above invention ideas, an implementable technical solution is proposed. In detail, the tool holder structure for roller processing includes a driving mechanism 1, a mounting platform 2 and a fixing mechanism 3, wherein the driving mechanism 1 includes a first lead screw 11 and a first guide rod 12 arranged side by side, and the first lead screw 11 and the first guide rod 12 are both parallel to the first horizontal direction; the mounting platform 2 is used to install the cutter, and the mounting platform 2 is provided with a threaded hole and a guide hole, the threaded hole is threadedly adapted to the first lead screw 11, and the guide hole is slidably adapted to the first guide rod 12, and the mounting platform 2 can move along the first horizontal direction with the rotation of the first lead screw 11; the fixing mechanism 3 includes a first fixing plate 31, a first reinforcing beam 32 and a support rod 33, and the first fixing plate 31 is spaced and Two first screws 11 are arranged side by side, and both ends of the first screw 11 are rotatably adapted to the two first fixed plates 31 respectively. Both ends of the first guide rod 12 are fixedly connected to the two first fixed plates 31 respectively. The first reinforcing beam 32 is arranged side by side with the first screw 11 and is arranged on the side of the first guide rod 12 away from the first screw 11. Both ends of the first reinforcing beam 32 are connected to the two first fixed plates 31 respectively.

Corresponding to the first sliding protrusion, the first reinforcing beam 32 is provided with a first sliding groove extending along the first horizontal direction, and the first sliding protrusion is slidably adapted in the first sliding groove.

[0033] Compared with the prior art, in the specific implementation process of this embodiment, when the cutter is cutting the roller, the mounting table 2 is always subjected to the reaction force of the roller, and the first reinforcing beam 32 and the support rod 33 can support the mounting table 2 to prevent the mounting table 2 from being subjected to excessive force and causing the first lead screw 11 to deform, thereby helping to maintain the processing accuracy of the tool holder structure for roller processing; not only that, during the rotation of the first lead screw 11 in this embodiment, since the support rod 33 is threadedly adapted to the first lead screw 11, the support rod 33 can move with the movement of the mounting table 2 and is always located on one side of the mounting table 2 to support the first lead screw 11 near the mounting table 2 to prevent the first lead screw 11 from bending.

[0034] Based on the above embodiments, a feasible implementation is proposed, where there are two support rods 33, and the two support rods 33 are symmetrically arranged on both sides of the mounting platform 2.
