Technical Field

[0001] The utility model belongs to the field of casting heat treatment equipment, and particularly relates to a material guiding structure for a casting heat treatment furnace. Background Technique

[0002] In the production and processing of castings, after casting, shaping, cooling, and grinding, a preliminary object with a certain shape, size, and performance is formed. However, at this time, the strength, hardness, and corrosion resistance of the casting are poor, and heat treatment is required. Usually, a heat treatment furnace is used to put the casting into it for heat treatment. During this operation, manual loading and unloading are carried out, which has risks and a large labor intensity. To solve this problem, a structure combining a bracket and a slide rail is adopted to enable the bracket to carry the casting in and out of the heat treatment furnace. However, when the casting on the bracket is removed, it still needs to be manually removed, resulting in poor production efficiency. Content of the Utility Model

[0026] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] As shown in the figure, a material guiding structure for a casting heat treatment furnace includes a base plate 1. On the upper side of the base plate 1, there is a heat treatment furnace 2 and a carrier 4 located in front of the feeding port of the heat treatment furnace 2. The carrier 4 can move back and forth horizontally on the base plate 1 and enter and exit the heat treatment furnace 2. The carrier 4 includes a frame 401 and a turning plate 402 lapped inside the frame 401. The front end of the turning plate 402 is rotatably connected to the front end of the frame 401. A telescopic unit 5 is fixedly connected to the bottom of the base plate 1. The top end of the telescopic part 501 of the telescopic unit 5 passes through the base plate 1 upward and can abut against the bottom of the turning plate 402. In this embodiment, a carrier 4 that can move horizontally in and out of the heat treatment furnace 2 is arranged on the base plate 1. The casting is loaded by the carrier 4 to enter and exit the heat treatment furnace 2, eliminating the need for workers to operate inside the heat treatment furnace 2 to pick up and place materials, greatly improving safety. And a turning plate 402 is arranged on the carrier 4. When it is necessary to move the casting down after heat treatment is completed, one end of the turning plate 402 can be lifted by controlling the telescopic unit 5, so that the casting slides off the turning plate 402 and falls onto the transfer rack placed below in advance, reducing the labor intensity of workers and saving time and effort.

[0028] Two slide rails 3 are fixedly connected to the upper side of the base plate 1, and the slide rails 3 are of an inverted T-shaped structure, extending from the front end of the upper surface of the base plate 1 into the heat treatment furnace 2. The four corners of the bottom of the frame 401 of the carrier 4 are all lapped on the slide rails 3 through I-shaped pulleys 7. On the one hand, the I-shaped pulleys 7 are used for limiting, and on the other hand, movement on the slide rails 3 is realized. In this embodiment, inverted U-shaped connectors are fixedly connected to the bottom of the frame 401 corresponding to the pulleys 7, and the pulleys 7 are all rotatably connected between the two side walls of the connectors through rotating shafts.

[0029] A stop block 8 is vertically fixedly connected to the front end of the slide rail 3 to limit the carrier 4.

[0030] A connection through groove 405 is opened in the middle of the front side of the frame 401. Fixed bosses 406 integrally formed are fixedly connected to the inner walls of both sides of the connection through groove 405 at the bottom of the frame 401. Sockets are opened on the inner side walls of the fixed bosses 406. A connection platform 404 integrally formed and matching the connection through groove 405 is provided in the middle of the front end of the turning plate 402. Rotating columns are fixedly connected to both sides of the connection platform 404, and the rotating columns are rotatably connected in the corresponding sockets.

[0031] Limit edges 403 are fixedly connected upward to the left and right sides and the rear side wall of the frame 401 to prevent parts from detaching from the carrier 4 due to inertia when the carrier 4 moves into the heat treatment furnace 2, especially when producing smaller parts.

[0032] The top end of the telescopic part 501 of the telescopic unit 5 is rotatably connected with an abutting member 6. The abutting member 6 includes an abutting part 601 that can abut against the bottom of the turning plate 402 and connecting parts 602 vertically located on the left and right sides of the abutting part 601. The top end of the telescopic part 501 of the telescopic unit 5 is rotatably connected between the two connecting parts 602 through a rotating pin. And when the abutting part 601 is in a horizontal state, the distance between the abutting part 601 and the top end of the telescopic part 501 of the telescopic unit 5 is less than the horizontal distance from the rotating pin to the front and rear end faces of the abutting part 601, ensuring that when the abutting member 6 does not abut against the carrier 4, when the abutting member 6 is inclined, the abutting part 601 will not completely tilt to one side of the telescopic part 501. Furthermore, when the telescopic unit 5 moves upward, the abutting part 601 can smoothly abut against the bottom of the turning plate 402. In this embodiment, a through hole 101 is provided on the substrate 1 corresponding to the telescopic part 501, and the telescopic part 501 is arranged through the through hole 101.

[0033] Support strips 407 are fixedly connected to the inner wall edges at the left, right and rear sides of the bottom of the frame 401, and the turning plate 402 can be horizontally lapped on the upper side of the support strips 407.

[0034] A groove 102 is provided at the front end of the substrate 1 between the two slide rails 3, which is convenient for the carrier 4 to move to the frontmost end of the slide rails 3. When the turning plate 402 is lifted, the casting can slide off the turning plate 402 and move to the transfer rack below.

[0035] A limiting block 408 is provided at the bottom of the rear side of the turning plate 402, which is used for limiting the abutting part 601 during the sliding process, so as to prevent the telescopic unit 5 from directly turning the turning plate 402 completely over.

[0036] Vertical columns are fixedly connected to the four corners of the bottom of the substrate 1.

[0037] In this embodiment, the telescopic unit 5 is a hydraulic cylinder or an electric telescopic rod.

[0038] The working process of this embodiment is as follows:

[0039] The castings are sequentially placed on the turning plate 402. The opening and closing door at the feeding port of the heat treatment furnace 2 is opened, the carrier 4 is moved to the position of the heat treatment furnace 2, and then the opening and closing door is closed for heat treatment. After the heat treatment is completed, the carrier 4 is moved out of the heat treatment furnace 2 until it moves to the stop block 8. At this time, the telescopic unit 5 is started. When the top end of the telescopic part 501 of the telescopic unit 5 drives the abutting member 6 to move upward until it contacts the turning plate 402 and continues to move upward, at this time, the abutting part 601 fits against the turning plate 402 under the action of the turning plate 402. Then continue to move upward. While the abutting part 601 moves at the bottom of the turning plate 402, it lifts the turning plate 402 for tilting and turning, so that the casting slides off the turning plate 402.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
