Description

Technical Field

[0001] The present invention relates to the technical field of mesh belt normalizing furnaces, and specifically refers to an auxiliary blanking method for shaft parts of a mesh belt isothermal normalizing furnace. Background Art

[0002] Shaft parts are one of the typical parts often encountered in production. According to different structural forms, shafts can be divided into stepped shafts, taper mandrels, smooth shafts, hollow shafts, crankshafts, camshafts, eccentric shafts, various lead screws, etc. It is mainly used in machinery to support transmission parts such as gears, belt pulleys, cams, and connecting rods to transmit torque and bear loads. When producing such parts, the blank needs to be heat-treated first. The heat treatment of the blank not only has a great impact on the cutting performance but also can refine grains, homogenize the structure, eliminate internal stress, and prepare for the final heat treatment. Currently, normalizing furnaces are commonly used in the industry for normalizing and other heat treatments. Mesh belt normalizing furnaces have the characteristics of high production efficiency and short cycle, and are widely used. However, the shapes and sizes of shaft parts are different, and the position and form when leaving the furnace are also different. The gaps between shafts are large and the space cannot be reasonably utilized. When transferred to the next process, manual labor is still required to uniformly standardize the placement, resulting in heavy work tasks and low work efficiency. Moreover, some shaft parts are large in size and weight, and the temperature is high when leaving the furnace. Prolonged labor will cause irreversible damage to the human body. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an auxiliary blanking method for shaft parts of a mesh belt isothermal normalizing furnace, which can automatically and quickly adjust the placement form of the workpiece when the shaft parts fall from the normalizing furnace and simply place the workpiece.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is: an auxiliary blanking method for shaft parts of a mesh belt isothermal normalizing furnace includes a vibration frame and an aggregate frame. The vibration frame is a cylindrical structure with openings at both the top and bottom. Inside the vibration frame, a first baffle and a second baffle are obliquely and oppositely cross - arranged downward. The first baffle is fixedly connected to the inside of the vibration frame obliquely downward. The lower end of the first baffle is above the lower end of the second baffle. The upper end of the second baffle is rotatably connected to the upper part of the vibration frame. The lower surface of the lower end of the second baffle is rotatably connected to one end of a linear adjustment mechanism. The other end of the linear adjustment mechanism is rotatably connected to the vibration frame. The aggregate frame is arranged below the second baffle. On the two outer vertical surfaces of the vibration frame, a vibration motor is respectively provided. At the four corners of the lower part of the vibration frame, a connecting part is respectively provided, and each connecting part is connected to a first support. Below each first support, a spring and a second support are successively provided. The first support and the second support are respectively fixedly connected to both ends of the spring;

[0005] The linear adjustment mechanism includes a first adjustment member and a second adjustment member. One end of the first adjustment member is rotatably connected to a third support, and the third support is fixedly connected to the vibration frame. The other end of the first adjustment member is sleeved outside the second adjustment member and can move along the second adjustment member. The other end of the second adjustment member is rotatably connected to a fourth support, and the fourth support is fixedly connected to the lower surface of the second baffle.

[0006] The shaft parts first fall onto the first baffle when coming out of the normalizing furnace. The shaft parts are adjusted to be parallel to the first baffle, and then slide down along the first baffle onto the second baffle and are adjusted to be parallel to the second baffle. After being adjusted by the first baffle and the second baffle, the shaft parts fall into the aggregate box from the gap between the first baffle and the second baffle in a unified form, that is, in a form parallel to the intersection line of the first baffle and the second baffle, and the state adjustment can be completed without manual placement; the vibration motor can also be started to drive the vibration frame to vibrate the shaft parts on the baffle, further assisting the large shaft parts to quickly complete the state adjustment.

[0007] Preferably, a number of first through holes are provided on the first adjustment member, and a number of second through holes are provided on the second adjustment member. The first through holes and the second through holes are adapted to each other, and a pin shaft is sleeved in the coincident first through holes and second through holes.

[0008] The beneficial effects of adopting the above technical solutions are as follows: When the shaft parts fall from the normalizing furnace, the present invention can automatically and quickly adjust the placement form of the workpiece, simply place the workpiece, reduce the labor cost, improve the placement efficiency, and increase the economic benefits.

Detailed Embodiment

[0012] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0013] As Figure 1 and 2 shown, an auxiliary blanking method for shaft parts of a mesh belt type isothermal normalizing furnace includes a vibration frame 4 and an aggregate frame 1. The vibration frame 4 is a cylindrical structure with upper and lower openings. Inside the vibration frame 4, a first baffle 2 and a second baffle 3 are arranged diagonally downward and crosswise. The first baffle 2 is fixedly connected to the inside of the vibration frame 4 diagonally downward. The lower end of the first baffle 2 is above the lower end of the second baffle 3. The upper end of the second baffle 3 is rotatably connected to the upper part of the vibration frame 4. The lower surface of the lower end of the second baffle 3 is rotatably connected to one end of a linear adjustment mechanism. The other end of the linear adjustment mechanism is rotatably connected to the vibration frame 4. The aggregate frame 1 is arranged below the second baffle 3. On the two outer vertical surfaces of the vibration frame 4, a vibration motor 9 is respectively arranged. At the four corners of the lower part of the vibration frame 4, a connecting part 8 is respectively arranged. Each connecting part 8 is connected to a first support 5. Below each first support 5, a spring 6 and a second support 7 are successively arranged. The first support 5 and the second support 7 are respectively fixedly connected to both ends of the spring 6.

[0014] Specifically, the linear adjustment mechanism includes a first adjustment part 11 and a second adjustment part 12. One end of the first adjustment part 11 is rotatably connected to a third support 10. The third support is fixedly connected to the vibration frame 4. The other end of the first adjustment part 11 is sleeved outside the second adjustment part 12 and can move along the second adjustment part 12. The other end of the second adjustment part 12 is rotatably connected to a fourth support 13. The fourth support 13 is fixedly connected to the lower surface of the second baffle 3.

[0015] A number of first through holes are arranged on the first adjustment part 11. A number of second through holes are arranged on the second adjustment part 12. The first through holes are adapted to the second through holes. A pin shaft is sleeved in the coincident first through holes and second through holes. The pin shaft fixedly connects the adjusted first adjustment part 11 and the second adjustment part 12 together. If it is necessary to change the gap size between the first baffle 2 and the second baffle 3 according to the diameter size of the shaft part so that the gap can only allow one shaft part to pass through, only the length of the second adjustment part 12 in the first adjustment part 11 needs to be changed and then fixed with a pin shaft. The linear adjustment mechanism can also be a hydraulic cylinder or a pneumatic cylinder.

[0016] The shaft parts come out of the normalizing furnace and first fall onto the first baffle 2. The shaft parts are adjusted to a state parallel to the first baffle 2. The shaft parts slide down along the first baffle 2 onto the second baffle 3 and are adjusted to a state parallel to the second baffle 3. After being adjusted by the two baffles, the shaft parts fall into the aggregate frame 1 from the gap between the first baffle 2 and the second baffle 3 in a unified form (i.e., a form parallel to the intersection line of the first baffle 2 and the second baffle 3), and there is no need for manual placement. When the shaft parts are relatively small, the state adjustment can be completed only by the two baffles. When the shaft parts are relatively large, the vibration motor 9 can be started to vibrate the shaft parts on the baffles so that the state adjustment can be completed quickly and effectively.

[0017] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
