Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing and relates to a rolling processing device for a beryllium bronze corrugated gasket. Background Art

[0002] like Figure 4 As shown, the raw material is 0.15mm thick beryllium bronze QBe-2-Y, and the shape is a wavy gasket. From the analysis of the raw material characteristics of beryllium bronze, beryllium bronze is a metal with high hardness and extremely low ductility (2.5%), and sheet metal forming itself is very difficult.

[0003] When the wave shape is pressed by direct stamping, the gasket as a whole will break, so the next best option is to use a punch to have workers stamp it out one wave at a time, but this efficiency is extremely slow. Summary of the invention

[0004] In view of this, the invention provides a beryllium bronze corrugated gasket rolling processing device, which can not only ensure that the gasket will not break during the corrugated pressing process, but also significantly improve the processing efficiency.

[0005] The technical solution of the present invention is:

[0006] A beryllium bronze wave-shaped gasket rolling processing device comprises a driving gear, a driven gear, a top, a keyway mandrel, a torque limiter, a support arm, a countersunk screw, a cover plate, a base, a mandrel, a bolt, a bearing, a small key, a large key and a spring;

[0007] The outer circle of the driving gear is a tooth shape, which is the same as the tooth shape of the wave-shaped gasket to be rolled, and a keyway hole is opened in the center;

[0008] The outer circle of the driven gear is a tooth shape, which is the same as the tooth shape of the wave-shaped gasket to be rolled, with a hole in the center, one end of the hole is chamfered 1×45°, and the center hole can be interference fit with the outer ring of the bearing;

[0009] The tip is cylindrical, with one end being a 90° cone, which matches the chamfer of the center hole of the driving gear;

[0010] The keyway mandrel is a stepped cylinder, the thin section is tightly pressed and fitted with the inner hole of the driving gear and fixed by a small key; the thick section has a keyway, the thick section is gap-fitted with the inner hole of the torque limiter and fixed by a large key;

[0011] The torque limiter is a finished part, one end of which is clamped on the lathe chuck and the other end has an inner hole with a keyway. The rotation of the lathe chuck drives the torque limiter to rotate, and the torque limiter drives the keyway spindle and the driving gear to rotate. When the torque on the driving gear exceeds the set torque of the torque limiter, the torque limiter 7 will lose the torque transmission function and play a protective role.

[0012] The support arm is fork-shaped, and each of the two forks has a hole at the front end, and the hole is interference fit with the core shaft; the tail of the support arm is a square strip, and there is a threaded hole on the end surface; the threaded hole is matched with the bolt; the tail of the support arm is embedded in the groove of the base and can slide, and after embedding, the support arm is flush with the plane on the base;

[0013] The cover plate is provided with four screw holes, and the screw holes are recessed;

[0014] The missing part of the base forms a rectangular parallelepiped after being matched with the cover plate. There are 4 threaded holes on the base, and the cover plate is fixed to the base by countersunk screws.

[0015] There is a long strip groove in the middle of the base, which matches the long strip at the tail of the support arm; there is a countersunk hole at one end of the base, and a small hole is further provided in the middle, and the bolt is inserted into the countersunk hole; a spring is provided around the bolt to provide elastic force.

[0016] The mandrel is cylindrical, connected to the driven gear through a bearing, and tightly matched with the inner hole of the bearing and the two fork-shaped holes of the support arm;

[0017] The bolt is a hexagonal bolt;

[0018] The base is mounted on the lathe tool holder;

[0019] The center is installed on the tailstock of the lathe; and the driving gear and the driven gear must be of the same height and aligned in width;

[0020] The torque limiter is installed on the lathe chuck to set the required limited torque;

[0021] Adjust the position of the tool holder, adjust the alignment of the two gear teeth, and further adjust the position of the tool holder to tighten the spring and provide a certain force.

[0022] Beneficial effects of the present invention:

[0023] The structure of the invention is simple and practical, and can complete the pressing of 0.15mm thick beryllium bronze QBe-2-Y corrugated gaskets, without breaking the gaskets, significantly improving the processing efficiency, and can be continuously rolled, and the efficiency is significantly improved. In addition, the product qualification rate is high, and the waveform is completed by mechanical structure rolling, which is easier to ensure the accuracy than the original manual processing by workers.
