Description

Technical Field

[0001] The utility model relates to the technical field of pipe fixtures, in particular to a pipe fixture clamping device used in high-frequency coil solid solution. Background Art

[0002] Solution treatment refers to a heat treatment process in which the alloy is heated to a high-temperature austenite zone and kept warm, so that the excess phase is fully dissolved into the solid solution and then quickly cooled to obtain a supersaturated solid solution. In the processing of stainless steel pipe fittings, it is necessary to perform solution treatment on them to eliminate the stress generated by the pipe fittings during the processing and restore the crystal structure. In the prior art, the solution treatment of pipe fittings is generally carried out in a solution furnace. However, this treatment method is suitable for large-scale pipe fittings processing, while for small batches of pipe fittings, the processing cost is relatively high; moreover, some companies have not updated their equipment and still use old-fashioned equipment. For old-fashioned equipment, manual hand-held pipe fittings are currently used to perform solution treatment on the pipe fittings through high-frequency coils. In this process, the requirements for operators are relatively high. Not only can the pipe fittings not touch the high-frequency coils, but the heating temperature is also high. The pipe fittings must be kept at high temperature for a certain period of time to achieve the effect of eliminating stress, which places certain requirements on the endurance and stability of the operator. Therefore, in view of the problems existing in the solution treatment of pipe fittings by old-fashioned equipment, the present invention provides a clamping device. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0023] refer to Figure 1-Figure 4 The utility model discloses a pipe clamping device for high-frequency coil solid solution, including an extension rod 1, a trigger 2 is hinged on the side wall of the extension rod 1, one end of the extension rod is bent and arranged to form an "eight" shape together with the trigger, which is convenient for operators to hold and operate. A fixed cylinder 3 is hinged on the end of the extension rod 1 away from the trigger 2. The fixed cylinder 3 is interference fit with one end of the extension rod 1. Under the action of external force, the fixed cylinder 3 and the extension rod 1 maintain a certain angle, and the angle between the two will not change under the action of their own gravity, so as to adapt to the operating habits of different operators. The state of the fixed cylinder clamping the pipe is as follows Figure 5 As shown, the clamping block can be retracted by pulling a trigger to achieve the purpose of fixing from the inside of the pipe 17.

[0024] A plurality of clamping blocks are arranged through the side wall of the fixed cylinder 3, and the clamping blocks move radially along the fixed cylinder 3, that is, the clamping blocks are arranged along the circumference of the fixed cylinder. A control member for controlling the radial movement of the clamping blocks is arranged in the fixed cylinder 3, and one end of the control member is connected to a control line 4, and the other end of the control line 4 is connected to the trigger 2, and can be extended and retracted toward the fixed cylinder at the same time under the action of the control member.

[0025] Furthermore, the control component includes a transmission rod 5 arranged in the fixed cylinder 3 along its axial direction, a retaining ring 6 is fixedly mounted on the transmission rod 5, a partition 7 is arranged in the fixed cylinder 3 for one end of the transmission rod 5 to pass through, the transmission rod and the partition are gap-matched, one end of the transmission rod 5 passing through the partition 7 is connected to the control line 4, a spring 8 is mounted on the transmission rod 5 located between the partition 7 and the retaining ring 6, both ends of the spring abut against the retaining ring and the partition, the partition 7 is arranged at a position close to the extension rod 1, and the other end of the transmission rod 5 is slidably connected to the clamping block through a guide block 9.

[0026] Furthermore, the clamping block includes an internally hollow slide groove 10, and a strip hole 11 is provided at the bottom of the slide groove 10 along its length direction. The length of the strip hole determines the sliding length of the guide block in the slide groove. The cross-section of the guide block 9 is T-shaped and extends into the slide groove 10. The width of the strip hole is smaller than the cross section of the guide block to prevent the guide block from escaping from the slide groove; the bottom surface of the slide groove 10 is an inclined surface and is inclined upward in the direction of the spring 8, so that when the transmission rod moves toward the extension rod, the clamping block moves toward the fixed cylinder under the action of the guide block.

[0027] Furthermore, a fixing block 12 is provided on the top surface of the slide groove 10, and fireproof materials 13, such as fireproof cotton, are provided on both sides of the fixing block 12 to prevent the fixing block from scratching the inner wall of the pipe. The middle part of the fixing block 12 is concavely arranged to clamp pipes of different diameters, for example, pipes with bends or concave shapes can also be clamped.

[0028] Furthermore, a retaining ring 14 is provided on the inner wall of the fixed cylinder 3 between the retaining ring 6 and the partition 7, and one side of the retaining ring 14 abuts against the end face of the slide groove 10, thereby limiting the clamping block and ensuring that the clamping block moves up and down. The inner diameter of the retaining ring 14 is larger than the outer diameter of the retaining ring 6. When the control line pulls the transmission rod, the retaining ring can pass through the retaining ring 14.

[0029] Furthermore, a conical head 15 is provided at the other end of the fixing tube 3. The diameter of the conical head is smaller than that of the fixing tube and mainly plays a guiding role, guiding the fixing tube to be inserted into the pipe fitting.

[0030] Furthermore, a protective tube 16 is provided on the side wall of the extension rod 1 along its length direction, and the control line 4 passes through the protective tube 16 .

[0031] When using the utility model, you only need to press the trigger, and pull the power transmission rod to move linearly under the action of the control line. At the same time, the guide block moves along the slide groove, and slides toward the fixed cylinder under the action of the inclined surface of the bottom surface of the slide groove. At this time, the fixed cylinder is inserted into the pipe fitting, and the trigger is released. Under the action of the spring, the transmission rod is reset, and in this process, the slide groove is reset, so that the fixed block and the inner wall of the pipe fitting are against each other, thereby achieving the clamping effect. Then operate the entire device and insert it into the high-frequency coil for solid solution.
