Description

Technical Field

[0001] The utility model relates to the technical field of flange production, in particular to forging quenching equipment for connecting flange production. Background Art

[0002] The connecting flange, also known as flange flange or flange, is a disc-shaped part. The basic principle of flange connection is to fix two pipes, pipe fittings or equipment to be connected on a flange plate, then add a flange gasket between the two flange plates, and finally tighten the two flange plates with bolts to make them tightly combined, thereby achieving connection and sealing.

[0003] In the production process of connecting flanges, quenching technology is often used to improve the overall performance. Although the current traditional forging quenching equipment can meet basic usage requirements, in actual use, water quenching is required for cooling after quenching, and the water quenching method of traditional quenching equipment mostly sprays liquid directly on the workpiece through a nozzle. This method cannot ensure that the cooling speed of various parts of the workpiece in the water is consistent, so it will cause quenching stress concentration, deformation or cracking caused by local cooling too fast or too slow. Therefore, there is an urgent need for a forging quenching equipment for connecting flange production. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a forging quenching device for connecting flange production.

[0007] In addition, a preferred structure is that a quenching machine body is provided on one side of the quenching machine platform, and an electromagnetic coil is installed on one side of the quenching machine body.

[0008] In addition, a preferred structure is that a drainage pipe is provided on one side of the bottom of the quenching machine.

[0009] In addition, a preferred structure is that a driving motor is installed in the middle of the mounting seat, and the output end of the driving motor extends out of the top wall of the mounting seat and is connected to the bottom wall of the rotating disk.

[0010] In addition, a preferred structure is that a plurality of side spray nozzles are installed on the outer side of the mounting plate.

[0012] In addition, a preferred structure is that a baffle is rotatably mounted on one side of the inner wall of the mounting groove, and a torsion spring is provided at the rotating connection of the baffle.

[0013] In addition, a preferred structure is that a main spray nozzle is fixedly mounted on one side of the baffle, and one end of the main spray nozzle is connected to a water pipe.

[0014] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A forging quenching equipment for connecting flange production includes a quenching machine 1, a rotating disk 3 is rotatably installed in the middle of the quenching machine 1 through a mounting seat 6, a plurality of heat-insulating cylinders 11 are installed on the upper part of the rotating disk 3 through a mounting disk 8, a cooling column 9 is sleeved and installed in the heat-insulating cylinder 11, the bottom of the cooling column 9 is connected to an electric push rod 14, and an installation groove 91 is opened inside the cooling column 9, and a main spray nozzle 12 is rotatably installed in the installation groove 91.

[0024] Furthermore, a quenching machine body 4 is disposed on one side of the quenching machine platform 1 , and an electromagnetic coil 41 is installed on one side of the quenching machine body 4 .

[0025] Furthermore, a drainage pipe 2 is provided at one side of the bottom of the quenching machine 1 , and waste water after water quenching is discharged through the drainage pipe 2 .

[0026] Furthermore, a driving motor 7 is installed in the middle of the mounting seat 6 , and an output end of the driving motor 7 extends out of the top wall of the mounting seat 6 and is connected to the bottom wall of the rotating disk 3 .

[0027] Furthermore, a plurality of side spray nozzles 10 are arranged on the outer side of the mounting plate 8 , and the side spray nozzles 10 can effectively cool the outer wall of the flange 5 .

[0028] Furthermore, a plurality of electric push rods 14 are installed at the bottom of the rotating disk 3 , and the telescopic ends of the electric push rods 14 pass through the rotating disk 3 and extend into the heat insulation tube 11 , and are connected to the bottom wall of the cooling column 9 .

[0029] Furthermore, a baffle 15 is rotatably mounted on one side of the inner wall of the mounting groove 91 , and a torsion spring 151 is provided at the rotation connection of the baffle 15 . The torsion spring 151 has a return torsion force during the torsion process, which effectively ensures the ejection effect of the main spray nozzle 12 .

[0030] Furthermore, a main spray nozzle 12 is fixedly mounted on one side of the baffle 15 , and one end of the main spray nozzle 12 is connected to a water pipe 13 .

[0031] In this embodiment, the flange 5 is placed on the mounting plate 8 on the rotating plate 3, and the driving motor 7 arranged in the mounting seat 6 drives the rotating plate 3 to rotate, and makes the flange 5 rotate to the electromagnetic coil 41. At this time, the quenching machine body 4 controls the electromagnetic coil 41 to heat the flange 5. Then, after the heating is completed, the electric push rod 14 arranged at the bottom of the rotating plate 3 is extended, and the cooling column 9 sleeved inside the insulation tube 11 is pushed out, wherein the main spray nozzle 12 in the cooling column 9 pops out from the mounting groove 91, and cooperates with the water pipe 13 to spray the liquid, and at the same time cooperates with the side spray nozzle 10 arranged on the outside of the mounting plate 8 to spray and cool the inner and outer walls of the flange 5 at the same time.

[0034] Among them, it is worth noting that the quenching machine body 4 and the electromagnetic coil 41 are existing quenching equipment, which convert electrical energy into thermal energy through the electromagnetic coil 41, so that the workpiece (flange 5) reaches the quenching temperature in a short time. Its specific principles and specific components are technical common sense well known to technical personnel in this field, so they will not be elaborated on.

[0035] In the utility model, after the quenching machine body 4 completes heating of the flange 5, the cooling column 9 rises under the action of the electric push rod 14, and the main spray nozzle 12 arranged inside pops out, and cooperates with the side spray nozzle 10 to spray and cool the inner and outer walls of the flange 5 at the same time. Compared with traditional quenching equipment, this mechanism can cool the flange 5 in a timely and effective manner, ensure uniform contact with the workpiece, ensure consistent cooling speed, improve quenching quality, reduce scrap rate, and improve work efficiency.
