Description

A stainless steel heat treatment apparatus Technical Field

[0001] This utility model relates to the field of stainless steel processing, and more particularly to a stainless steel heat treatment apparatus. Background Technology

[0002] After stainless steel is processed, it is often subjected to external forces, which can cause stress. This stress can not only affect the performance and service life of the pipe, but may also lead to safety hazards.

[0003] The conventional method for stress relief of stainless steel is heat treatment. Through the process of heating, holding and cooling, the internal structure of the material is changed, thereby achieving the purpose of stress relief. However, during the heat treatment process, the stainless steel is sequentially placed in an open flame. Because the stainless steel is supported by a support frame, the heat treatment of the stainless steel is insufficient, resulting in inadequate stress relief. Summary of the Invention

[0004] To address the technical deficiencies in the background art, this utility model proposes a stainless steel heat treatment device, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A stainless steel heat treatment apparatus includes: a support base, a cylinder, a vertical plate, and a heating base. At least two support bases are provided. The cylinder is arranged laterally. Gaskets are provided at the front and rear edges of the cylinder. The cylinder is supported above the two support bases by two gaskets. Each gasket is composed of two ring plates, and a plurality of protrusions are provided between the two ring plates. The protrusions are fixed to the outside of the cylinder and arranged sequentially along the circular surface of the cylinder. A placement chamber is provided inside the cylinder. A vertical plate is provided on one side of the cylinder, and a baffle is provided on the other side of the placement chamber. One side of the cylinder is open, and the baffle is placed at the opening of the cylinder. The placement chamber, the vertical plate, and the baffle reciprocate along the opening direction of the cylinder. Each support seat is provided with at least two guide gears, and one edge of each guide gear extends out of the support seat. Each guide gear is meshed with several protrusions. The placement chamber is composed of two semi-circular arc plates, and the ends of the two semi-circular arc plates are spliced ​​together. The heating base is located between the two support seats and the cylinder.

[0006] Each of the support seats has an arc-shaped side that contacts the two washer rings, and the side matches the outer surface of the two washer rings. A slot is formed on the arc-shaped surface of each support seat, and one edge of the guide gear extends out of the slot. A shaft runs through the center of the guide gear and is fixed inside the support seat by the shaft. One of the two support seats has a shaft-rotating motor inside, and the shaft-rotating motor is engaged with the shaft of the guide gear by gears.

[0007] A foot pad is provided below each of the two support seats.

[0008] The cylinder body has several strip-shaped grooves, with a crossbar between every two strip-shaped grooves; one or more of the crossbars of the cylinder body have a sliding groove, and the openings of the sliding grooves face downwards; several sliding blocks are provided at the outer edge of the upright plate, and each sliding block is embedded in a corresponding sliding groove; the upright plate moves back and forth in one direction along the sliding grooves using the sliding blocks.

[0009] The two semi-circular arc plates of the placement compartment are connected at one end by a splicing plate. Each of the two splicing plates has an embedding groove on its upper surface, and the two embedding grooves are connected in a groove shape on opposite sides. An insertion groove is formed on an adjacent vertical surface of each of the two embedding grooves, and a connecting plate is embedded in each insertion groove. A protrusion is formed on the upper or lower surface of the connecting plate, and the protrusion is embedded in one side of the insertion groove. The other end of the two semi-circular arc plates of the placement compartment is connected to a rotating assembly. The rotating assembly is composed of two arc plates and a shaft. An embedding opening is formed at the edge of one arc plate of the rotating assembly, and the other arc plate of the rotating assembly has an extension block. The extension block of the other arc plate is embedded in the embedding opening of the first arc plate, and is connected laterally by a insert rod. One side of one of the two semi-circular arc plates of the placement compartment is fixed to the vertical plate, and the other side of the semi-circular arc plate is fixed to the baffle.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention uses a rolling mechanism to ensure that the stainless steel placed inside is heated evenly, thereby avoiding uneven heating and the need for repeated heat treatment.

[0013] The process involves pulling the placement chamber out of the cylinder, then pulling out a movable semi-circular plate in a fan shape to place the stainless steel to be processed inside.

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0023] As shown in Figures 1 to 7, a stainless steel heat treatment device includes: a support base 1, a cylindrical body 2, a vertical plate 3, and a heating base 5. At least two support bases 1 are provided. The cylindrical body 2 is arranged horizontally, and gaskets 21 are respectively provided at the front and rear edges of the cylindrical body 2. The cylindrical body 2 is supported above the two support bases by two gaskets 21. Each gasket 21 is composed of two ring plates, and several protrusions 23 are provided between the two ring plates of the gasket 21. The protrusions 23 are fixed to the outside of the cylindrical body 2 and are arranged sequentially along the circular surface of the cylindrical body 2. A placement chamber 30 is provided inside the cylindrical body 2. A vertical plate 3 is provided on one side of the placement chamber 30, and a baffle 31 is provided on the other side of the placement chamber 30. One side of the cylinder 2 is open, and the baffle 31 is placed at the opening of the cylinder 2. The placement chamber 30, the vertical plate 3, and the baffle 31 move back and forth along the opening direction of the cylinder 2. At least two guide gears 12 are provided in each support seat 1, and one edge of each guide gear 12 extends out of the support seat 1. Each guide gear 12 is meshed with several protrusions 23. The placement chamber 30 is composed of two semi-circular arc plates, and the ends of the two semi-circular arc plates are spliced ​​together. The heating base 5 is located between the two support seats 1 and the cylinder 2.

[0024] This invention uses a rolling mechanism to ensure that the stainless steel placed inside is heated evenly, thereby avoiding uneven heating and the need for repeated heat treatment.

[0025] In this process, the placement chamber 30 is pulled out of the cylinder 2. After being pulled out, the movable semi-circular plate is pulled out downwards in a fan shape to place the stainless steel to be processed inside. Then, the movable semi-circular plate is reset and locked. Finally, the placement chamber 30 is reset back into the cylinder 2. At this time, the guide gears 12 of the support seats 1 on both sides engage and roll. The cylinder 2 in the rolling state drives the placement chamber 30 inside to roll, and the stainless steel placed in the placement chamber 30 rolls. The heating seat 5 ignites the flame, allowing the flame to pass through the cylinder 2 and contact the stainless steel in the placement chamber 30, so that the stainless steel can be heat-treated evenly by rolling.

[0026] With the above structure, it should be further explained that each guide gear 12 protrudes to the edge outside the support base 1 and is embedded between the two ring plates of the washer ring 21. This arrangement can prevent left and right movement and derailment when the guide gear 12 meshes with several protrusions 23.

[0027] Furthermore, the washer ring 21 has a certain thickness. When the washer ring 21 is placed outside the support seat 1, it can create a gap between the support seat 1 and the cylinder 2, thereby further preventing the contact area between the support seat 1 and the cylinder 2 from being too large and causing excessive rolling friction.

[0028] The outer surface of the placement chamber 30 has several mesh openings, which allow the flame to come into contact with the stainless steel and also prevent the stainless steel from falling outwards.

[0029] Each support 1 has an arc-shaped side that is in contact with the two washers 21 and matches the outer surface of the two washers 21. A slot is opened on the arc-shaped surface of each support 1, and an edge of the guide gear 12 extends out of the slot. A shaft runs through the center of the guide gear 12 and is fixed inside the support 1 by the shaft. One of the two support 1s has a shaft-rotating motor 11 installed inside it. The shaft-rotating motor 11 is engaged with the shaft of the guide gear 12 by gears.

[0030] With the above structure, it should be further explained that the support base 1 uses the gasket ring 21 to keep the heated cylinder 2 away from its surface, thereby avoiding the heat from affecting the shaft motor 11 inside the support base 1.

[0031] The shaft-rotating motor 11 of this utility model is electrically connected to external control equipment such as computers via conduits. It is also connected to external power sources via control equipment to further control the electrical connection and disconnection between them.

[0032] A foot plate 8 is provided under each of the two support seats 1.

[0033] With the above structure, it should be further explained that the foot plate 8 is used to raise the two support bases 1 and the cylinder 2, thereby exposing the placement space for placing the heating base 5, and also providing space for the heating base 5 to be ignited.

[0034] The cylinder 2 has several strip grooves on its outside, and a crossbar is between every two strip grooves; one or more of the crossbars of the cylinder 2 have a sliding groove 24, and the openings of the sliding grooves 24 face downwards; several sliding blocks are provided on the outer edge of the vertical plate 3, and each sliding block is embedded in a corresponding sliding groove 24. The vertical plate 3 moves back and forth in one direction along the sliding grooves 24 using several sliding blocks.

[0035] With the above structure, it should be further explained that the setting of several sliding grooves 24 allows the upright plate 3 to move back and forth within a limited area, avoiding the occurrence of derailment.

[0036] Several of the grooves in the cylinder 2 are used to guide the flame so that the flame can directly contact the placement chamber 30.

[0037] The two semi-circular arc plates of the placement compartment 30 are connected at one end by a splicing plate 33. Each of the two splicing plates 33 has an embedding groove 35 on its upper surface. The two embedding grooves 35 are connected in a groove shape on their opposite sides. An insertion groove is formed on an adjacent vertical surface of each of the two embedding grooves 35. A connecting plate 36 is embedded in each of the two insertion grooves. A protrusion 37 is formed on the upper or lower surface of the connecting plate 36, and the protrusion 37 of the connecting plate 36 is embedded in one side of the insertion groove. The other end of the connection between the two semi-circular arc plates of the placement compartment 30... One end is connected to a rotating component 34; the rotating component 34 is composed of two arc-shaped plates and a shaft. An insertion opening is opened at the edge of one arc-shaped plate of the rotating component 34, and the other arc-shaped plate of the rotating component 34 is provided with an extension block. The extension block of the other arc-shaped plate is embedded in the insertion opening of the first arc-shaped plate and is connected by a plug rod through laterally; one side of one of the two semi-circular arc-shaped plates of the placement compartment 30 is fixed to the upright plate 3, and the other side of the semi-circular arc-shaped plate is fixed to the baffle 31; a handle 32 is provided on the side of the baffle 31 away from the placement compartment 30.

[0038] With the above structure, it should be further explained that the two semi-circular arc plates of the placement compartment 30 are connected by an extension block embedded in the insertion port at one end, and the semi-circular arc plate is fanned outward along the transverse insertion rod to expose the internal space for placing stainless steel.

[0039] After the stainless steel is placed, the two semi-circular splicing plates 33 are closed, and the two splicing plates 33 are combined to form an embedding groove 35 between and above. The embedded groove 35 is then used to insert the connecting plate 36 into the insertion groove. After the connecting plate 36 is inserted, the two protrusions 37 of the connecting plate 36 pull the splicing plates 33 on both sides to prevent the movable semi-circular plates from falling off.

[0040] The upper surface of the heating base 5 is arc-shaped and recessed inward; several through holes are opened on the arc-shaped surface of the heating base 5, and the heating base 5 is hollow. A gas guide tube is inserted from the outside of the heating base 5. One end of the gas guide tube of the heating base 5 extends into the hollow area of ​​the heating base 5, and the other end of the heating base 5 is connected to the gas valve 53. The gas valve 53 is connected to a gas tank 52 by a gas pipe.

[0041] With the above structure, it should be further explained that the gas valve 53 of this utility model is an electrically controlled gas valve 53. The gas valve 53 is connected to a circuit board 50 by an electrical conduit, and the circuit board 50 is connected to an external control device by an electrical conduit. The external control device controls the opening and closing of the gas valve 53. With this setting, the opening and closing size of the gas valve 53 can be controlled, thereby controlling the output of combustible gas from the gas tank 52, and thus further controlling the size of the flame after ignition.

[0042] The heating base 5 ignites the combustible gas using an ignition structure 51. The ignition structure 51 is also connected to the circuit board 50 by an electrical conduit. The ignition command is transmitted to the circuit board 50 through an external control device, and then the circuit board 50 feeds the command back to the ignition structure 51, thereby igniting the combustible gas.

[0043] The ignition structure 51 used in this utility model is a piezoelectric ceramic igniter.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
