Description

Technical Field

[0001] This utility model relates to the field of necking equipment technology, specifically a necking device for automobile frame support tubes. Background Technology

[0002] The car frame is a frame structure that spans the front and rear axles of a car, commonly known as the main beam, and is the base of the car. The car frame support tube is a part of the frame. When the end of the support tube is connected to other parts, it is often necessary to use a reducing machine to reduce the diameter of the tube opening, so that the tube opening has a smaller diameter front end.

[0003] However, existing shrinking machines only clamp and fix the support tube using fixtures, lacking support and blocking measures for the non-shrinking end of the support tube. When the shrinking machine shrinks the support tube, relying solely on the fixture for fixation, the support tube is prone to axial movement, thus affecting the shrinking quality. Furthermore, the excessively long sections of the support tube lack support. Therefore, a shrinking device for automotive frame support tubes is proposed. Utility Model Content

[0024] In use, the length of the telescopic rod of the through-hole control adjustment cylinder 9 can be adjusted to regulate the distance between the shrinking machine 6 and the clamping base plate 5.

[0025] The drive mechanism consists of a motor 12, a lead screw 19, and a movable block 21. The movable block 21 is fixedly installed at the bottom of the baffle 11.

[0032] In use, the support tube is placed in the slot of the clamping base plate 5. The height of the clamping top plate 4 is adjusted by controlling the length of the telescopic rod of the lifting cylinder 3. The clamping top plate 4 is moved downward to clamp the support tube. Then, the length of the telescopic rod of the adjusting cylinder 9 is adjusted by controlling the through hole to adjust the distance between the shrinking machine 6 and the clamping base plate 5. The shrinking nozzle 10 of the shrinking machine 6 is controlled to squeeze the end of the support tube to complete the shrinking work. Multiple support plates 15 set on the processing table 1 can support the bottom of the excessively long support tube. The support plates 15 are slidably connected to the processing table 1 through the sliding component. The distance between the multiple support plates 15 can be adjusted to support support tubes of different lengths. The baffle 11 can support the end of the support tube to prevent the support tube from sliding when the shrinking nozzle 10 squeezes the support tube. The drive mechanism on the baffle 11 can freely adjust the distance between the baffle 11 and the clamping base plate 5 to ensure that the baffle 11 can be used for support tubes of different lengths.
