Description

Technical Field

[0001] The utility model relates to the technical field of quenching furnaces, in particular to a wide-mouth discharge type quenching furnace. Background Art

[0002] Powder metallurgy is a process technology for preparing metal powder or using metal powder (or a mixture of metal powder and non-metallic powder) as raw material, forming and sintering, to manufacture metal materials, composite materials and various types of products. Generally, a quenching furnace is used for firing. Quenching is to put the workpiece into the furnace and heat it to a quenching temperature above the critical point and maintain it for a period of time, and then quickly take the workpiece out of the furnace and put it into the quenching liquid (oil or water) for quenching. For example, a powder metallurgy quenching furnace proposed in the prior art, although this technology improves the uniform heating of the workpiece in the quenching furnace, it is not convenient to put in and take out the quenched objects during use, and the subsequent cleaning of the quenching furnace is also very inconvenient. For this reason, there is an improved technology on the market that proposes a quenching furnace for powder metallurgy, which relates to the field of quenching furnace technology. It includes a base, an opening and closing device and a quenching furnace. The top right side of the base is connected with the opening and closing device, and the top left side of the base is connected with the quenching furnace. When in use, the object is hung on the hook, and the bracket is pushed to drive the rotating rod to rotate in the fixed ring to change the position of the hook. After the object is placed, the hydraulic rod is extended to push the furnace shell to move left, so that the plug block is inserted into the slot to close the quenching furnace. The left heating layer and the right heating layer are operated at the same time to increase the temperature in the furnace for firing. After the firing is completed, the hydraulic rod is retracted to pull the push block and the furnace shell to move backward to open the quenching furnace, so as to facilitate the removal of the object and the subsequent cleaning work. When cleaning, the baffle can be opened to discharge the carbon deposits in the furnace from the discharge pipe;

[0003] However, in the above-mentioned improved technology, although the furnace body is arranged into two parts on the left and right, and has a discharge port with a width consistent with the diameter of the furnace body when opened, but since the rest of the furnace body is fixed except for the part that can be opened and closed, the discharge port is always facing the part of the furnace body that can be opened and closed, that is, when loading and unloading from the front side, only half of the width of the discharge port can be used, resulting in that in actual use it cannot achieve the technical effect of being able to facilitate the removal of objects. In order to improve this problem, it is necessary to further improve the alignment structure. Utility Model Content

DETAILED DESCRIPTION

[0026] 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.

[0027] Reference Figures 1 to 4 The utility model provides a wide-mouth discharge type quenching furnace: comprising a workbench 2, a furnace body and a heating device, the heating device is consistent with the prior art and is arranged on the inner wall of the barrel body;

[0028] like Figure 1 As shown, in order to provide installation positions for the hydraulic cylinder 19 and the guide column 15, the bottom wall of the workbench 2 and near the four corners are fixedly connected with the base 1, and the upper wall of the workbench 2 and near the right end are fixedly connected with the side baffle 14. The hydraulic cylinder 19 is arranged between the side baffle 14 and the barrel body. The side baffle 14 is used as the force point of the hydraulic cylinder 19. The guide column 15 is slidably connected to the inner wall of the side baffle 14 to maintain the stability of the movement of the guide column 15.

[0029] like Figure 1 , Figure 2 as well as Figure 3As shown, in order to reduce interference during discharge, the furnace body is composed of a lower end cover 8, an upper end cover 6 and a barrel body. The lower end cover 8 is rotatably connected to the upper wall of the workbench 2 through a plane bearing. A carbon slag cleaning pipe 9 is fixedly connected to the lower wall of the lower end cover 8. The carbon slag cleaning pipe 9 passes through the inner wall of the workbench 2 and extends to the bottom of the workbench 2. A rotating drive structure for driving the furnace body to rotate along the axis of the carbon slag cleaning pipe 9 is arranged between the carbon slag cleaning pipe 9 and the lower wall of the workbench 2. The rotating drive structure includes a driving motor 11, a first gear 12 and a second gear 13. The driving motor 11 is driven by The fixed plate 10 is fixedly connected to the lower wall of the workbench 2 and is located on the left side of the carbon slag cleaning pipe 9. The first gear 12 and the second gear 13 are respectively fixedly connected to the outer wall of the driving motor 11 and the carbon slag cleaning pipe 9, and the outer wall of the first gear 12 and the outer wall of the second gear 13 are meshed with each other. When the driving motor 11 rotates, the carbon slag cleaning pipe 9 can be driven to rotate by the first gear 12 and the second gear 13, thereby driving the upper end cover 6, the lower end cover 8 and the fixed flap 7 to rotate, and the fixed flap 7 is rotated to the opposite direction of the loading and unloading operation surface, so that the material taking port can be presented to the greatest extent;

[0030] like Figure 1 As shown, in order to maintain the structural strength of the barrel body, the upper end cover 6 is arranged on the upper wall of the workbench 2 through a supporting structure, and the upper end cover 6 is opposite to the lower end cover 8 in the upper and lower directions. The supporting structure includes a column 3 and a suspension 4. The column 3 is fixedly connected to the upper wall of the workbench 2 and is close to the left end. The suspension 4 is fixedly connected to the upper wall of the column 3 and extends toward the upper end of the upper end cover 6. The upper wall of the upper end cover 6 is rotatably connected to one end of the suspension 4 extending to the upper end cover 6 through a rotating shaft 5. The upper end cover 6 is rotatably connected to the upper wall of the workbench 2 through the column 3, the suspension 4, and the rotating shaft 5, which can avoid deformation due to reduced support below the upper end cover 6 after the barrel body is opened, thereby improving the structural strength.

[0031] like Figure 1 , Figure 2 as well as Figure 3 As shown, in order to realize wide-mouth discharging, the barrel body is composed of a fixed flap 7, a first movable flap 17 and two groups of second movable flaps 18. The fixed flap 7 is fixedly connected between the upper end cover 6 and the lower end cover 8 and is located on the left side of the two groups of steps 22. The arc length of the outer wall of the fixed flap 7 in a top view is one-fifth of the circumference of the outer wall of the barrel body. By constraining the dimensional relationship between the arc length of the fixed flap 7 and the barrel body diameter, the connection strength between the upper end cover 6 and the lower end cover 8 can be maintained, and a sufficiently large discharging port can be obtained after the barrel body is opened;

[0032] like Figure 1As shown, in order to maintain the accuracy of the barrel body when it is closed, the first movable flap 17 is slidably connected to the left side of the side baffle 14 through a guide structure, and the two groups of second movable flaps 18 are respectively rotatably connected to the front and rear sides of the first movable flap 17 through multiple groups of hinges. The guide structure includes two groups of guide columns 15, and the two groups of guide columns 15 are distributed up and down and fixedly connected to the side of the first movable flap 17 away from the fixed flap 7 in sequence. The sides of the two groups of guide columns 15 away from the first movable flap 17 all penetrate the side baffle 14 and are slidably connected thereto. The outer walls of the two groups of guide columns 15 and located between the first movable flap 17 and the side baffle 14 are sleeved with springs 16. When the barrel body is opened and closed, the first movable flap 17 is maintained by the two groups of guide columns 15. The position of the direction other than the axial direction of the guide column 15 when moving left and right ensures that it can be accurately closed after each opening and closing. The spring 16 is for the hydraulic cylinder 19 to drive the first movable flap 17 and the second movable flap 18 to open and close. When the second movable flap 18 takes precedence over the first movable flap 17;

[0033] like Figure 1 , Figure 2 As shown, an opening and closing driving structure for driving the second movable flap 18 and the first movable flap 17 to open and close is provided between the second movable flap 18 and the side baffle 14. The opening and closing driving structure includes two groups of hydraulic cylinders 19 and support rods 20. The two groups of hydraulic cylinders 19 are rotatably connected to the side of the side baffle 14 facing the first movable flap 17 and are respectively located at the front and rear sides of the guide structure. The two groups of support rods 20 are respectively fixedly connected to the ends of the extended shafts of the two groups of hydraulic cylinders 19. The ends of the two groups of support rods 20 away from the hydraulic cylinders 19 are respectively rotatably connected to the outer walls of the two groups of second movable flaps 18 through two groups of rotating seats 21. The upper end cover 6 is relatively close to the lower end cover 8. Steps 22 are provided between the sides, and the barrel body is provided between the upper end cover 6 and the lower end cover 8. When the hydraulic cylinder 19 extends the shaft, the second movable flap 18 and the first movable flap 17 are driven to move toward the two sets of steps 22 through the support rod 20, and finally enclosed with the fixed flap 7 to form a completed barrel body, and the enclosing force is maintained. The connecting surfaces of the barrel body are sealed by common insulation sealing materials on the market, and the barrel body is insulated by insulation materials consistent with the prior art. When the hydraulic cylinder 19 extends the shaft and retracts, it can drive the second movable flap 18 and the first movable flap 17 to move toward the side baffle 14 to open the barrel body to form a discharge port.

[0034] Working principle: When the hydraulic cylinder 19 extends its shaft, it drives the second movable flap 18 and the first movable flap 17 to move toward the two sets of steps 22 through the support rod 20, and finally closes with the fixed flap 7 to form a complete barrel body and maintains the closing force. The connecting surfaces of the barrel body are sealed by common insulation sealing materials on the market. When the hydraulic cylinder 19 extends its shaft and retracts, it can drive the second movable flap 18 and the first movable flap 17 to move toward the side baffle 14 to open the barrel body to form a discharge port. The first movable flap 17 is maintained by two sets of guide columns 15 when moving left and right except for the position along the axial direction of the guide column 15, ensuring that it can be accurately closed after each opening and closing. The spring 16 is for the hydraulic cylinder 19 to drive the first movable flap 17 and the second movable flap 18 to open and close the second movable flap 18. The flap 18 takes precedence over the first movable flap 17 in action. The arc length of the outer wall of the fixed flap 7 when viewed from above is one-fifth of the circumference of the outer wall of the barrel body. By constraining the dimensional relationship between the arc length of the fixed flap 7 and the diameter of the barrel body, the connection strength between the upper end cover 6 and the lower end cover 8 can be maintained, and a sufficiently large discharge port can be obtained after the barrel body is opened. The upper end cover 6 is rotatably connected to the upper wall of the workbench 2 through the column 3, the suspension 4, and the rotating shaft 5, which can avoid deformation due to reduced support below the upper end cover 6 after the barrel body is opened, thereby improving the structural strength. When the driving motor 11 rotates, the carbon slag cleaning pipe 9 can be driven to rotate through the first gear 12 and the second gear 13, thereby driving the upper end cover 6, the lower end cover 8 and the fixed flap 7 to rotate, and the fixed flap 7 is rotated to the opposite direction of the loading and unloading operation surface, so that the material taking port can be presented to the greatest extent.
