Roller extrusion forming roller steel wire tension spring reset device for cylinder parts with variable wall thickness

Abstract

The invention discloses a roller extrusion forming roller steel wire tension spring resetting device of a variable-wall-thickness barrel part. The resetting device relates to a forming device. Each layer of roller squeezing mechanism comprises three roller wheels and a corresponding resetting device. The resetting device comprises a seat body, a steel wire rope, a first pulley, a second pulley, atension spring, a limiting plate, a baffle, a nut and a limiting bolt. The roller wheel shaft penetrates out of the seat body and is sleeved by the limiting plate. The baffle is arranged on the limiting plate. The limiting bolt is arranged on the seat body to abut against the baffle. The positions of roller wheel shafts are controlled by controlling the contact length between the limiting bolt andthe baffle. The limiting bolt is connected with the nut. The nut is screwed after the position of a roller wheel type groove is adjusted. The second pulley is fixedly arranged on the roller wheel shaft. The lower end of the steel wire rope is connected with the first pulley and the second pulley in a winding mode, the tension spring is installed at the middle of the steel wire rope, and the upperend of the steel wire rope is connected with an upper cross beam. By means of the roller extrusion forming roller steel wire tension spring resetting device of the variable-wall-thickness barrel part, the assembling and adjusting difficulty of the forming device is reduced, and rapid resetting is realized. Moreover, quick online adjustment can be carried out, so that the continuity of productionis easily ensured. Neither air cylinders nor air pumps are needed. The structure is simple. The cost is low.

Description

technical field [0001] The invention relates to the technical field of metal precision plastic forming, in particular to a roll extrusion forming roller steel wire tension spring reset device for variable wall thickness cylinder parts. Background technique [0002] Most of the cylindrical parts with variable wall thickness are made of high-strength alloy steel. The traditional production method adopts the "pressing-punching-extension" process to form a straight-walled cylinder, and then machine cutting to process different wall thicknesses, and the material utilization rate is extremely low. (Many products are less than 40%), the tool consumption is large, and the production cost is high. In addition, the method of powerful spinning can also form this kind of parts, but there are disadvantages such as many times of spinning, long production cycle, low production efficiency, and difficulty in releasing the cylinder from the mandrel after spinning. Therefore, it is impossible...
