Description

Technical Field

[0001] The utility model relates to a heat treatment processing device for a bimetallic barrel. Background Art

[0002] The barrel is an important part of an extruder. In order to improve the service life and load-bearing capacity of the barrel, save raw materials and energy consumption, a bimetallic barrel has been proposed. This alloy layer is compounded in a common nitrided barrel by centrifugal casting. First, the common barrel is processed, alloy powder is added into the barrel, the two ends are closed with covers, and then heated to melt the alloy powder. Then, the barrel is placed flat on rollers, and the barrel is driven by the rollers to rotate around its axis, so that the liquid alloy in the barrel generates centrifugal force and adheres to the inner wall of the barrel. After that, it is gradually cooled to form an alloy layer in the barrel wall. The end cover and the barrel are fixed by welding. The welding process is troublesome, and after the alloy layer is formed, the welded parts at both ends of the barrel need to be cut. The cut end covers need to be processed and reused, which further increases the processing procedures and reduces the work efficiency. Content of the Utility Model

Detailed implementation mode

[0023] As Figure 1-2 shown, a heat treatment processing device for a bimetallic barrel of the present utility model includes a heat treatment box 1. A rotating shaft 2 is horizontally installed in the middle of the heat treatment box 1. There are two groups of rotating shafts 2 symmetrically arranged along the front-rear direction, and the rotation directions of the two groups of rotating shafts 2 are the same. Both ends of the rotating shaft 2 pass through the heat treatment box 1 and are connected to the bearing seat 4. One end of the rotating shaft 2 is connected to the driving motor 6 through the pulley assembly 5. A heating element 3 is installed on the upper part of the heat treatment box 1. The heating element 3 is arranged along the axial direction of the rotating shaft 2. An arc surface 31 is processed at the lower part of the heating element 3. The length of the heating element 3 is greater than the length of the barrel 10. Side openings 12 are symmetrically processed on both sides of the heat treatment box 1 for the barrel 10 to pass through;

[0024] An auxiliary material platform 9 is arranged on the right side of the heat treatment box 1. A positioning groove 91 is processed on the upper part of the auxiliary material platform 9 for placing the barrel 10. The cross-sectional shape of the positioning groove 91 is V-shaped (see Figure 3 ). Above the auxiliary material platform 9, there is a hoisting mechanism 8. The lifting hook 81 is installed at the lower part of the hoisting mechanism 8 through the pulley mechanism 82. There are two groups of lifting hooks 81;

[0025] An end cover 11 is detachably installed at both ends of the barrel 10 through bolts. Threaded process holes 102 are processed on the end faces of the barrel 10 in a matching manner. A hanging buckle 111 is fixedly arranged on the outside of the end cover 11;

[0026] Pull rods 7 are arranged on the left side of the heat treatment box 1 and the right side of the auxiliary material platform 9. Hooks 71 are arranged at the ends of the pull rods 7 facing the heat treatment box 1;

[0027] After alloy powder is evenly poured into the barrel 10, end covers 11 are installed at both ends and placed on the auxiliary material platform 9. The pull rod 7 pulls the barrel 10 into the heat treatment box 1 and between the rotating shafts 2. The rotating shaft 2 drives the barrel 10 to rotate. The heating element 3 supplies heat to the barrel 10. After the alloy powder is heated, it evenly adheres to the inner wall of the barrel 10 and forms an integral alloy layer 101 after cooling (see Figure 4 ).

[0028] The device installs detachable end caps with buckles at both ends of the barrel, pulls the barrel into the heat treatment box by means of a pull rod, positions the barrel by using two groups of parallel rotating shafts, and drives the barrel to rotate by the frictional force between the surface of the rotating shaft and the barrel. It cooperates with the heating element to perform heat treatment on the barrel, so that the alloy powder melts and adheres to the inner wall surface of the barrel to form an alloy layer. Then, the barrel is pulled out by the pull rod. The barrel is convenient for feeding and discharging materials, and the end caps can be reused, the positioning is convenient, and the cost is saved.

[0029] When specifically used, to facilitate the understanding of the present invention, it is described in conjunction with the accompanying drawings:

[0030] The barrel has a margin at both ends during processing, and threaded process holes are processed at both ends of the barrel. During operation, first, alloy powder is evenly poured into the barrel. Then, end caps are installed at both ends of the barrel through bolts, and a closed space is formed inside the barrel. The whole barrel is lifted by a hoisting mechanism and placed on an auxiliary material platform. Hooks are provided on the outer side of the end caps and are connected to the lifting hooks below the hoisting mechanism. Then, the pull rod on the left side of the heat treatment box passes through the side openings on both sides of the heat treatment box, and the hook at the end of the pull rod is connected to the buckle on the end cap. The pull rod pulls the barrel from the auxiliary material platform into the heat treatment box and between the rotating shafts. The surface of the rotating shaft supports the barrel. After the rotating shaft rotates, the frictional force between the surface of the rotating shaft and the barrel is used to drive the barrel to rotate (see Figure 5 ), at the same time, the heating element supplies heat to the barrel, and the alloy powder in the barrel adheres evenly to the inner wall of the barrel after being heated. After the heating element is heated for a period of time and then turned off, the liquid alloy forms an alloy layer integrated with the barrel after cooling; after the heat treatment is completed, the rotating shaft stops rotating, and the pull rod on the right side of the auxiliary material platform pulls the barrel from the heat treatment box to the auxiliary material platform. Then, the barrel is removed from the auxiliary material platform through the hoisting mechanism. After removing the end caps, the parts with threaded process holes at both ends of the barrel are cut off.
