Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a handheld Lock ring crimping device. Background Technology

[0002] The current process in the refrigeration industry involves joining two pipes together using a traditional flame welding method, which requires the addition of flux (silver rings) during welding. This traditional welding method, which uses open flames, poses safety hazards, and the silver ring flux used is expensive and requires relatively skilled operators.

[0003] There is an urgent need to develop and design a device that can replace open flame welding, which can meet production efficiency requirements and complete the operation without the use of open flame. Utility Model Content

[0005] This utility model provides the following technical solution: a handheld Lock ring crimping device, comprising:

[0006] The drive unit is a cylindrical structure designed for handheld use.

[0007] The clamp body is threadedly mounted on the front end of the drive unit;

[0008] Two jaw assemblies are provided, with their ends hinged to the jaw body and arranged in a V-shape to form a symmetrical structure. The front ends of the two jaws are movably connected by a first positioning pin, a second positioning pin, and a third positioning pin, respectively.

[0009] Preferably, the driving device includes a cylinder body, a hydraulic cylinder, a top piece, a connector, and a button seat. The hydraulic cylinder is located inside one end of the cylinder body, the connector is threaded to the other end of the cylinder body, one end of the cylinder body is threaded to the clamp body, the piston end of the hydraulic cylinder is connected to the top piece, and the two sides of the top piece respectively abut against and contact the two clamp jaw assemblies. The button seat is detachably installed at one end of the cylinder body.

[0010] Preferably, the jaw assembly includes a jaw and a pressure claw, wherein the end of the jaw is hinged to the jaw body, and one end of the pressure claw is hinged to the front end of the jaw.

[0011] Preferably, the pliers include a body, wherein the front end of the body is provided with a U-shaped groove for mounting the clamping claws, the rear bottom surface of the body is provided with an inclined surface, and a roller is rotatably mounted at the end of the inclined surface.

[0012] Preferably, the front end of the top member is a sharp structure, and both sides of the sharp structure are in contact with the roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a driving device to bring one end of two clamping jaw assemblies closer together, thereby achieving a tight connection between two pipes. This replaces the traditional open flame welding process, which not only greatly reduces the occurrence of safety accidents, but also eliminates the need for flux, significantly reducing costs. Furthermore, the equipment is simple to operate and requires minimal skill from the operator. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0021] This utility model provides a handheld Lock ring crimping device, such as Figure 1-4 As shown, it includes:

[0022] Drive unit 1, drive unit 1 is a cylindrical structure for handheld use;

[0023] The clamp body 2 is threadedly installed at the front end of the drive device 1;

[0024] Two jaw assemblies 3 are provided, with their ends hinged to the jaw body 2 and arranged in a V-shape to form a symmetrical structure. The front ends of the two jaws are movably connected by the first positioning pin 4, the second positioning pin 5, and the third positioning pin 6, respectively.

[0025] The device uses a drive unit 1 to bring one end of two clamping jaw assemblies 3 close to each other, thereby achieving a clamping connection between the two pipes. This replaces the traditional open flame welding process, which not only greatly reduces the occurrence of safety accidents, but also eliminates the need for flux, significantly reducing costs. Furthermore, the device is easy to operate and requires minimal skill from the operator.

[0026] In this embodiment, the drive device 1 includes a cylinder body 11, a hydraulic cylinder 12, a top member 13, a connector 14, and a button seat 15. The hydraulic cylinder 12 is disposed inside one end of the cylinder body 11, and the connector 14 is threadedly connected to the other end of the cylinder body 11. One end of the cylinder body 11 is threadedly connected to the clamp body 2. The piston end of the hydraulic cylinder 12 is connected to the top member 13, and the two sides of the top member 13 respectively abut against and contact the two clamp claw assemblies 3. The button seat 15 is detachably installed at one end of the cylinder body 11.

[0027] Specifically, during operation, pressing the button seat 15 activates the hydraulic cylinder 12. The piston end of the hydraulic cylinder 12 drives the front end of the top piece 13 to move, causing the top piece 13 to squeeze the ends of the two jaw assemblies 3, bringing the other point of the two jaw assemblies 3 closer to each other, thus achieving a tight connection of the pipe body. The operation is simple and convenient, and the use of a hydraulic system ensures the effect and stability of the crimping.

[0028] In this embodiment, the jaw assembly 3 includes a jaw 31 and a pressure claw 32, wherein the end of the jaw 31 is hinged to the jaw body 2, and one end of the pressure claw 32 is hinged to the front end of the jaw 31.

[0029] Specifically, the clamp 31 is in an inclined state, and the pressure claw 32 is in a horizontal state. When the end of the clamp 31 is raised, the pressure claw 32 moves downward under the action of the hinge, thereby achieving the crimping of the tube body.

[0030] In this embodiment, the pliers 31 includes a main body 311, wherein the front end of the main body 311 is provided with a U-shaped groove 312 for mounting the pressure claw 32, the rear bottom surface of the main body 311 is provided with an inclined surface 313, and a roller 314 is rotatably mounted at the end of the inclined surface 313. The front end of the top member 13 is a sharp structure, and the two sides of the sharp structure respectively abut against the roller 314.

[0031] Specifically, when the top member 13 moves forward, both sides of the top member 13 press against the contact roller 314 and cause the roller 314 to rotate. When the top member 13 continues to move forward, in cooperation with the inclined surface, the end of the clamp 31 is raised, thereby causing the pressure claw 32 to move downward and realize the crimping of the tube body.

[0032] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
