The invention provides a gas spring necking machine, and belongs to the technical field of machines. The gas spring necking-in machine solves the technical problem that the end portion of an existing gas spring steel tube is large in extrusion deformation during the necking process. The gas spring necking machine comprises a machine frame, the machine frame comprises a top plate and a bottom plate, and the top plate and the bottom plate are fixedly connected through a supporting plate. The top plate is fixedly provided with a worktable plate, a guide rail is fixedly disposed on the worktable plate, a sliding block is connected with the guide rail in a sliding mode, a necking-in wheel is arranged on the sliding block, and the worktable plate is further fixedly provided with a first drive device used for driving the sliding block to move in the length direction of the guide rail. The gas spring necking machine further comprises a pneumatic chuck which comprises a cylinder, a hollow shaft is connected with the inside of the cylinder in an inserted mode, a clamping jaw is inserted into the hollow shaft, and the supporting plate is fixedly provided with a second drive device used for driving the hollow shaft to rotate. An adjusting device used for adjusting the height of a steel tube is arranged under the pneumatic chuck. When necking is carried out on the end portion of the steel tube, extrusion deformation of the end portion of the steel tube is small, and the gas spring necking machine can meet different requirements for necking sizes.
Description
technical field [0001] The invention belongs to the technical field of machinery and relates to a gas spring necking machine. Background technique [0002] Gas spring is an industrial accessory with functions of support, cushioning, braking, height adjustment and angle adjustment, depending on its characteristics and application fields. According to the structure and function of the gas spring, it can be divided into free gas spring, self-locking gas spring, traction gas spring, random stop gas spring and so on. Gas springs in the prior art generally include steel pipes, piston rods, pistons, sealing guide sleeves, fillers, in-cylinder control elements, out-of-cylinder control elements and joints. During the processing of the gas spring, it is necessary to shrink the steel pipe. [0003] The necking of steel pipes in the prior art is usually formed by integral cavity extrusion, which shrinks the large circle into a circle with a small diameter. When the diameter difference...
