Description

Technical Field

[0001] The utility model relates to a spraying heat preservation device, in particular to a two-axis movable thermal spraying heat preservation device, belonging to the technical field of spraying heat preservation. Background Art

[0002] In the thermal spraying of workpieces, the spray powder needs to be sprayed on the surface of the workpiece under high temperature to form an ideal spray layer. However, sometimes the temperature of the site and the characteristics of the workpiece itself will cause the temperature of the sprayed surface to lose, which will affect the spraying effect.

[0003] In order to reduce the temperature loss phenomenon during the thermal spraying process of the workpiece, it is extremely necessary to add a heat preservation device. However, since the thermal spraying operation is carried out in a high temperature environment, the heat preservation device cannot be manually operated and used. It is necessary to design a device that can be freely placed and moved in a high temperature environment. The two-axis mobile platform of the utility model can perform reciprocating motion of the XY axis in a high temperature environment, which solves the disadvantages caused by the inability to manually touch the workpiece to be sprayed during the spraying process, and is convenient for moving the heat preservation device at any time. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a two-axis movable thermal spray insulation device, which consists of a two-axis movable platform and an insulation module, and can perform reciprocating motion of the XY axis, and the overall structure is not covered with a protective cover. When the sprayed workpiece needs to be insulated, the insulation module moves to a suitable position and covers the workpiece to be sprayed to provide insulation assistance; when the spraying operation is completed, the insulation module moves to the initial position after the spray gun is removed, and does not affect the placement of the workpiece.

[0005] The technical solutions adopted by the utility model to solve the technical problems are as follows:

[0006] A two-axis movable thermal spray insulation device comprises an insulation module, a two-axis movable platform and a spray gun entry and exit hole, wherein the insulation module comprises a front cover, a flame spray gun mounting frame, a plasma flame spray gun, a flame baffle ring, a spray chamber, a pipeline chamber, a cabinet, a pipeline channel and a rear cover, wherein the pipeline chamber is arranged at the outer end of the spray chamber; the two-axis movable platform comprises an integrated frame, an X-axis movable track, an X-axis servo motor, a Y-axis servo motor, a Y-axis movable track and a fixed foot, the insulation module is arranged on the two-axis movable platform, and the insulation module is driven by the X-axis servo motor or the Y-axis servo motor to move along the X-axis movable track or the Y-axis movable track; the plasma flame spray gun enters and exits the insulation module through the spray gun entry and exit hole.

[0007] There are six plasma flame spray guns, which are evenly installed around the flame baffle ring. Six flame holes are arranged on the flame baffle ring at positions corresponding to the plasma flame spray guns. One end of each plasma flame spray gun is fixed on the corresponding flame spray gun mounting frame, and the other end extends into the spray chamber through the corresponding flame hole, ensuring that the flame can pass through the flame hole without burning the gun body of the plasma flame spray gun installed at the opposite position, thereby forming a high-temperature environment around the workpiece.

[0008] The spray chamber is a hollow structure, which is convenient for covering the workpiece to be sprayed and ensuring the moving space of the spray gun during the spraying operation; the spray chamber and the flame baffle ring are both sandwich designs, and water circulation cooling can be carried out inside to prevent high temperature from damaging the pipeline harness and the plasma flame spray gun.

[0009] The outer wall of the flame retaining ring is provided with a flame retaining ring cooling circulating water inlet, the inner wall is provided with a flame retaining ring cooling circulating water outlet, and a flame retaining ring water storage interlayer is provided inside.

[0011] The pipeline channel is provided with a combustible gas pipeline and a cooling circulating water pipeline. The combustible gas pipeline and the cooling circulating water pipeline are connected to the pipeline warehouse through the pipeline channel through the inside of the cabinet for arrangement and installation. The pipeline parts extending outside the pipeline channel are hoisted on the top of the spray room, which saves space and is convenient for installation and fixation.

[0012] The positive and beneficial effects of the utility model are as follows:

[0013] The utility model is composed of a two-axis mobile platform and a heat preservation module, which can perform reciprocating motion of the XY axis, and the overall structure is not covered with a protective cover.

[0014] The base of the two-axis mobile platform of the utility model is an integrated welded frame, and the power is driven by the servo motor to drive the gear rack to drive the insulation module to reciprocate along the X-axis or Y-axis. When installed, it can be leveled by the ground feet and fixed by the fixed feet. It has a simple structure, convenient operation and strong practicality.

[0015] The two-axis mobile platform of the utility model can perform reciprocating motion of the XY axis in a high temperature environment, which solves the disadvantage that the workpiece to be sprayed cannot be manually touched during the spraying process, and is convenient for moving the heat preservation device at any time.

[0016] The thermal insulation module of the utility model is composed of a front cover, a flame spray gun mounting frame, a plasma flame spray gun, a flame baffle ring, a spray chamber, a pipeline chamber, a cabinet, a pipeline channel and a rear cover.
