Embodiment 1

[0019] Such as figure 1 As shown in the schematic diagram of the structure of the extrusion coating device, it at least includes the extrusion coating device body part fixed on the frame 11. The extrusion coating device body is composed of the launch section 1, the stabilizing section 7, the same inner diameter of the cylinder to be repaired. The receiving section 10 is composed of the transmitting section 1 and the stabilizing section 7 are fixedly connected by a flange, and the flange connection is sealed by an annular rubber ring or a rubber pad, and the two ends of the cylinder 8 to be repaired are connected to the stabilizing section 7 and the receiving section respectively. The segments 10 are detachably connected by screw rods.

[0020] One end of the launch section 1 is fixedly connected to the stable section 7 through a flange, and the other end is fixed with a plug through the flange. The middle part of the plug is a compressed air inlet 6, and the launch section 1 i...

Embodiment 2

[0028] Such as figure 2 As shown in the structural schematic diagram of the rotary extrusion coating device, the rotary extrusion coating device 2 in the above embodiment is an integrated structure formed by sequentially connecting and fixing the tapered section 20, the helical section 21 and the extrusion coating section 22. The purpose of the tapered section is to save After the alloy powder enters the helical section, the helical thrust makes the rotary extruder rotate, so that the alloy powder enters the cylinder 8 through the extrusion section, and then the alloy powder is more evenly extruded onto the inner wall of the cylinder 8.

Abstract

The invention relates to the field of workpiece repair, and especially to a n inner extrusion coating using vacuum melting method to repair damaged parts. The device at least comprises an extrusion coating device body fixed on a frame (11); the extrusion coating device body is composed of a transmitting section having a same diameter as a cylinder to be repaired (8), a stable section (7) and a receiving section (10). The transmitting section (1) and the stable section (7) are connected and fixed by a flange; two ends of the cylinder to be repaired (8) are respectively detachably connected with the stable section (7) and the receiving (10) through screw rods; a rubber ball (3) is arranged in the transmitting section (1) near a connection end with the stable section (7); and a rotary extrusion coating apparatus (2) is arranged in the transmitting section (1) at the other end. The device can meet inner wall coating process for cylinders with different diameters and lengths, and a vacuum cladding technology is employed to realize the repair of hydraulic oil cylinder and other cylinder parts.

Description

technical field [0001] The invention relates to the field of workpiece repair, in particular to an internal extrusion coating device and an extrusion coating method for repairing damaged parts by adopting a vacuum cladding method. Background technique [0002] Vacuum cladding is a common part repair method in remanufacturing technology. Using vacuum cladding to repair damaged parts, one of the important processes is to evenly coat the prepared self-dissolving alloy powder on the surface of the workpiece according to the thickness required by different parts. [0003] For the coating of the outer circle surface of shaft parts and other external surfaces, it is easier to use rotary scraping and manual local scraping. For cylinder parts, due to the different bore sizes and lengths of cylinder parts, it is more difficult to coat the inner wall. At present, there is no better coating device for the inner wall of cylinder parts at home and abroad. This device is aimed at differ...
