Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe flaring machines, and more particularly to a steel pipe flaring machine for automobile exhaust pipe production. Background Technology

[0002] An exhaust pipe flaring device is a specialized piece of equipment that expands the end of a steel pipe using mechanical force. Its core components include a flaring end, a hydraulic cylinder, and a tapered rod. During operation, the hydraulic cylinder pushes the tapered rod into the tapered hole of the flaring end, causing the equally divided flaring units to open radially evenly, thereby expanding the steel pipe end from the inside out.

[0003] However, conventional flaring devices can generally only flare steel pipes of one specification. When flaring steel pipes of different specifications is required, the pressure head needs to be replaced. However, the existing replacement method is cumbersome and requires a long downtime, which affects production efficiency. Furthermore, when flaring different steel pipes, the center line of the pressure head and the center line of the steel pipe need to be kept at the same height, which requires adjusting the position of the pressure head, which is quite troublesome.

[0004] Therefore, those skilled in the art have provided a steel pipe flaring machine for automobile exhaust pipe production to solve the problems mentioned in the background art. Utility Model Content

The first spring 104 is sleeved on the outer wall of one end of the pull rod 102, so that the inclined block 108 is more firmly fixed inside the slot 106.

[0020] Reference Figure 1 , Figure 2 and Figure 4The positioning mechanism 2 includes a first fixed plate 201, a fixed ring 203 between two side plates 5, multiple dampers 208 on the inner wall of the fixed ring 203, and a second spring 204 sleeved on the outer wall of the damper 208. The other end of the damper 208 and the second spring 204 are connected to a positioning block 205. Through the positioning mechanism 2, the center line positions of different steel pipes can be kept at the same height, thereby saving adjustment time and improving processing efficiency. A motor 202 is set on one side of the outer wall of the first fixed plate 201. The output end of the motor 202 is connected to a bidirectional threaded rod 207. The outer walls of both ends of the bidirectional threaded rod 207 are threaded with sliders 206. A clamping plate 209 is connected to one side of the outer wall of the slider 206. The motor 202 drives the bidirectional threaded rod 207 to rotate, thereby causing the slider 206 to drive the two clamping plates 209 to move, thereby fixing one end of the steel pipe through the clamping plates 209. Hydraulic rods 11 are set on both the upper and lower sides of the outer wall of the second fixed plate 4. The other end of the hydraulic rods 11 are connected to The device is attached to the outer wall of one side of the fixed base 101.

[0021] Working principle: When using this device, the steel pipe is first inserted into the middle of the fixing ring 203. Under the action of multiple dampers 208 and the second spring 204, the steel pipe is fixed by the positioning block 205. Then, the control module 6 controls the motor 202 to drive the bidirectional threaded rod 207 to rotate, thereby causing the two sliders 206 to move the clamping plate 209 on one side of their outer wall towards each other, thus fixing both sides of the steel pipe. Then, the control module 6 controls the two hydraulic rods 11 to move the fixing seat 101 towards one end of the steel pipe, thereby flaring one end of the steel pipe through the pressure head 103. When it is necessary to flare steel pipes of different specifications, pull the pull rods 102 on both sides outward, thereby moving the inclined locking block 108 outward, causing the inclined locking block 108 and the locking groove 106 to disengage, thereby releasing the pressure head 103 from the fixing base 101. When installing another pressure head 103, insert the fixing block 107 into the fixing base 101. When it reaches the designated position, the first spring 104 resets, thereby causing the inclined locking block 108 and the locking groove 106 to re-engage, thereby fixing the pressure head 103.
