Cross rolling device for wrench processing

Abstract

The invention discloses a cross rolling device for wrench processing. The cross rolling device for wrench processing comprises a feeding and conveying mechanism, a cross rolling mechanism, a base, a control mechanism and a mobile manipulator mechanism. The base comprises a base chassis, a left side foundation pillar and a right side foundation pillar; the cross rolling mechanism comprises a positioning assembly, an upper roller, a lower roller, an upper roller drive motor, a lower roller drive motor, and a power transmission system for driving the upper roller and the lower roller to co-rotateat the same speed; the upper roller is connected with the upper roller drive motor; the lower roller is connected with the lower roller drive motor; the upper roller drive motor, the lower roller drive motor, the power transmission system and the control mechanism are connected; the mobile manipulator mechanism is matched with the control mechanism; and the mobile manipulator mechanism is matchedwith the cross rolling mechanism. According to the cross rolling device for wrench processing provided by the invention, the automation degree is high, one initial rod material enters the cross rolling device, two rod materials can be processed at one time, the production efficiency is high, and the raw materials are saved by 10 percent to 20 percent.

Description

【Technical field】 [0001] The invention relates to the technical field of cross rolling, in particular to a cross rolling device used for wrench processing. 【Background technique】 [0002] Cross wedge rolling refers to the continuous local deformation of the cylindrical billet between the dies of two rollers or between two flat dies, and the shape of the rolled part is consistent with the shape of the groove at the bottom of the die. Cross wedge rolling can be roughly divided into two categories: roll cross wedge rolling and plate cross wedge rolling. Among them, the forming principle of roller cross wedge rolling: two rollers rotate in the same direction, driving the circular billet to rotate in the opposite direction, so that the shape of the rolled part is consistent with the shape of the groove at the bottom of the mold. [0003] At present, in the process of processing wrenches, the rolling method commonly used in cross wedge rolling of round steel is to first cut the w...

Problems solved by technology

[0003] At present, in the process of processing wrenches, the rolling method commonly used in cross wedge rolling of round steel is to first cut the whole round steel into short bars of corresponding length according to the length of the rolled piece, and then roll them. However, only one part can be processed each time the roll rotates one revolution, and the processing efficiency is low, resulting in waste of steel and increased production costs.
