Embodiment 1

[0053] For pipes with different cut lengths, each pipe is required to keep Figure 6 The case where the length L1 of the middle and non-diameter section is uniform: wherein, the left slide rail 623 between the left front cylinder mounting block 622 and the left support block 624 is covered with a spring, and the left front cylinder mounting block 622 can slide on the left slide rail 623 , when the push rod 502 pushes the pipe to the clamping position, the front end of the pipe contacts the left front baffle plate 631 at the protruding position to push the left front block cylinder mounting block 622 to move, and the push rod 502 pushes the rear end of each pipe to the The left fixed clamping block 641 is clamped at the same position (that is, the rear end position of each pipe is kept uniform under the condition of different cutting lengths of the pipes), and then the left front baffle 631 retreats and resets, and the left electric spindle 801 advances and shrinks each time Th...

Embodiment 2

[0079] The same as the first embodiment will not be repeated, the difference is that this embodiment is suitable for keeping each pipe after shrinking such as Figure 7 The case where the length L2 of the reduced diameter section shown is uniform. Among them, before processing, first adjust the left front block cylinder mounting block 622 to slide to an appropriate position on the left slide rail 623 and then use screw locking to fix the relative position of the left front block cylinder mounting block 622 and the left slide rail 623, when the push rod 502 When the pipe is pushed to the clamping position, the front end of the pipe is in contact with the protruding left front baffle 631. Since the position of the left front baffle 631 is locked and fixed, it cannot be pushed, so that the front end of each pipe is at the same position, and then clamped (That is, the front end position of each pipe is kept uniform under the condition of different cutting lengths of the pipes), an...

Abstract

The invention discloses a short metal pipe diameter reducing device. The device comprises a machine frame which is arranged on a table top plate, a bilateral hopper mechanism, a bilateral clamping andopening reducing mechanism, a bilateral pushing mechanism and a control system, and the bilateral hopper mechanism, the bilateral clamping and opening reducing mechanism, the bilateral pushing mechanism and the control system are arranged on the machine frame; the bilateral hopper mechanism comprises a hopper mechanism which is symmetrically provided with two stock bins; the bilateral clamping opening reducing mechanism comprises two clamping and opening reducing mechanisms which are oppositely arranged on the table top plate and are positioned on the two sides of the hopper mechanism; the bilateral pushing mechanism comprises two pushing mechanisms symmetrically arranged on the bottom surface of the table top plate, wherein two transverse feeding mechanisms are symmetrically and transversely fixed on the upper surface of the table top plate and are opposite to the discharge port of the hopper mechanism, and a longitudinal pushing mechanism is longitudinally and fixedly arranged between the two clamping and opening reducing mechanisms; and the control system comprises a touch screen connected with a circuit and a PLC. According to the device, the machining efficiency is high, thequality is good, the precision is high, the device is suitable for opening reducing machining of metal pipes with different lengths and machining parameters, operation is simple, and the automation degree is high.

Description

technical field [0001] The invention relates to a metal pipe shrinking device, in particular to a short metal pipe diameter reducing device used for thin-walled metal pipes. Background technique [0002] Patent: CN 205816584U (Notice No.) discloses a spinning type automatic copper tube necking machine, including a spinning compression device, a linear propulsion mechanism, a length-setting mechanism, a workpiece clamping mechanism, a feeding device and a discharging device. The copper pipe is pushed out from the hopper, and the rear-end cylinder pushes the pipe to the positioning plate to realize positioning, and then the clamping mechanism clamps the copper pipe, and the spinning device is close to the copper pipe under the action of the linear propulsion mechanism to realize shrinkage, and then realizes through the unloading device. Blanking. [0003] The patent CN 205816584U (announcement number) has the following disadvantages: [0004] First, its processing actions in...
