Description

Technical Field

[0001] The utility model relates to the technical field of grouting sleeve processing, in particular to a novel automatic pipe shrinking and feeding machine. Background Art

[0002] A grouting sleeve is a grouting splicing device used for steel bar connection. It is mostly tubular in shape. There are many tubular forms of grouting sleeves. Among them, the variable-diameter grouting sleeve is one of them. Its specific operation is to preheat and roll one end of the pipe diameter to cause deformation of one end of the grouting sleeve and reduce the diameter of the pipe orifice.

[0003] In the prior art, the above operations all require manual feeding and processing of the grouting sleeve, which leads to unstable working efficiency and relatively average working efficiency. In order to avoid such problems, a novel automatic pipe shrinking and feeding machine is proposed to solve the existing problems. Content of the Utility Model

The guide plate is fixedly arranged on the top of the bottom plate through a bracket. A high-frequency heating coil is fixedly arranged on the top of the bottom plate and on one side of the guide plate through a bracket. A three-axis roller press is fixedly connected to the top of the bottom plate and on one side of the high-frequency heating coil. An electric telescopic rod is fixedly connected to the top of the bottom plate through a bracket. A feeding ring sleeve is fixedly connected to one side of the extending end of the electric telescopic rod. A plurality of clamping frames are slidably arranged around the surface of the feeding ring sleeve. An extrusion ring is fixedly connected to the top of the bottom plate through a bracket and is used in cooperation with the clamping frame. A metal pipe is placed inside the guide plate.

[0006] Preferably, a limiting sleeve is fixedly connected to the bottom of the guide plate through a bracket. A limiting rod is slidably connected inside the limiting sleeve. A first return spring is fixedly connected between the limiting rod and the limiting sleeve.

[0007] Preferably, a bearing bracket is fixedly connected to the top of the limiting rod.

[0009] Preferably, one side of the adjacent slider is fixedly connected to the inner wall of the clamping frame.

[0010] Beneficial effects

[0011] The utility model provides a new type of automatic pipe shrinking and feeding machine. Compared with the existing technology, it has the following beneficial effects: by arranging a feeding ring sleeve at the top of the bottom plate and arranging a movable clamping rack inside the feeding ring sleeve, the metal pipe can be easily clamped and fed through the driving of the electric telescopic rod and the clamping cooperation between the feeding ring sleeve and the clamping rack, thereby facilitating the clamping and feeding of the metal pipe and improving its processing efficiency.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0018] Please refer to Figures 1-4 , the utility model provides a technical solution: a new type of automatic pipe shrinking and feeding machine, including a bottom plate 1 and a material guiding plate 2. The material guiding plate 2 is fixedly arranged on the top of the bottom plate 1 through a bracket. A high-frequency heating coil 3 is fixedly arranged on the top of the bottom plate 1 and on one side of the material guiding plate 2 through a bracket. A three-axis roll press 4 is fixedly connected to the top of the bottom plate 1 and on one side of the high-frequency heating coil 3. A metal pipe 16 is placed inside the material guiding plate 2. As a detailed explanation: The high-frequency heating coil 3, also known as an electric heating coil and a heating coil, can convert electrical energy into heat energy to heat an object, which is a form of utilization of electrical energy. Compared with general fuel heating, electric heating can obtain a higher temperature (such as arc heating, with a temperature of more than 3000 °C), and it is easy to realize automatic temperature control and remote control.

[0019] Further: To facilitate the automatic clamping, preheating, feeding, and rolling processing of the metal pipe 16, an electric telescopic rod 5 is fixedly connected to the top of the bottom plate 1 through a bracket. One side of the extending end of the electric telescopic rod 5 is fixedly connected to a feeding ring sleeve 6. A plurality of clamping frames 7 are slidably arranged around the surface of the feeding ring sleeve 6. An extrusion ring 8 that is used in conjunction with the clamping frame 7 is fixedly connected to the top of the bottom plate 1 through a bracket. A limiting sleeve 9 is fixedly connected to the bottom of the guide plate 2 through a bracket. A limiting rod 10 is slidably connected inside the limiting sleeve 9. A first return spring 11 is fixedly connected between the limiting rod 10 and the limiting sleeve 9. The top of the limiting rod 10 is fixedly connected to a supporting bracket 12. A plurality of sliding grooves 13 are equidistantly arranged around one side of the feeding ring sleeve 6. A slider 14 is slidably connected inside the sliding groove 13. A second return spring 15 is fixedly connected between the adjacent slider 14 and the sliding groove 13. One side of the adjacent slider 14 is fixedly connected to the inner wall of the clamping frame 7.

[0020] During use, first place the metal pipe 16 on the top of the guide plate 2 and the supporting bracket 12. Then start the high-frequency heating coil 3 and the electric telescopic rod 5. The high-frequency heating coil 3 is started for preheating to heat the processing surface of the subsequent metal pipe 16. The electric telescopic rod 5 is started to drive the feeding ring sleeve 6 to move to the right. When the feeding ring sleeve 6 moves to the right, it will enclose one end of the metal pipe 16 inside itself. Then the feeding ring sleeve 6 continues to move to the right. When the feeding ring sleeve 6 continues to move to the right, it will drive the inclined surface of the clamping frame 7 to come into extrusion contact with the extrusion ring 8. The specific extrusion state is as follows: The extrusion ring 8 annularly extrudes the outermost surface of a plurality of clamping frames 7 to cause the clamping frames 7 inside the feeding ring sleeve 6 to clamp the metal pipe 16. As the extending end of the electric telescopic rod 5 drives the feeding ring sleeve 6 to continue to move, the feeding ring sleeve 6 drives the processing end of the metal pipe 16 to pass through the high-frequency heating coil 3 through the clamping frame 7. The heated end of the metal pipe 16 will move to the central clamping part of the three-axis roll press 4 as it moves. Finally, start the three-axis roll press 4 to roll and reduce the diameter of the heated end of the metal pipe 16.
