Description

Technical Field

[0001] This utility model relates to the field of wedge cross rolling heat treatment technology, specifically to a material preparation device for a split mesh belt normalizing furnace. Background Technology

[0002] The wedge cross rolling process uses two rollers with wedge-shaped dies, rotating in the same direction along the wedge's advance, driving the workpiece to rotate in the opposite direction. Through radial compression and axial extension, the billet is gradually rolled into a long, stepped rotating shaft. This process offers advantages such as high material utilization, high efficiency, low noise, and low pollution. Heat treatment includes tempering, normalizing, quenching, and annealing. Normalizing often employs a split-type mesh belt isothermal normalizing furnace. This equipment consists of three main parts: a heating furnace, an air-cooling chamber, and an isothermal furnace. The shafts rolled by the wedge cross rolling process are sequentially transferred from the heating furnace to the air-cooling chamber and then to the isothermal furnace. The height of the three furnace sections decreases progressively, resulting in height differences during the transfer. During each stage of transmission, the shafts frequently become irregularly arranged and jam the mesh belt, causing equipment failures and downtime. Based on these problems, a high-temperature and impact-resistant material handling device for a split-type mesh belt normalizing furnace needs to be developed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a split-type mesh belt normalizing furnace material preparation device with simple structure, convenient disassembly and assembly, high temperature resistance, impact resistance, and good stability. It can effectively solve the problem of material jamming and machine stoppage caused by irregular material dropping of shaft parts.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a material handling device for a split-type mesh belt normalizing furnace, including a clamping sleeve, a conical sleeve, a connecting plate, a support shaft, a first support, a second support, a baffle, a cylinder, a third support, a proximity switch, a rotating shaft, a connecting piece, and a bushing. The first support and the second support are respectively fixedly connected to the outer walls of both sides of the normalizing furnace. The support shaft passes through the normalizing furnace, and the two ends of the support shaft are rotatably connected to the first support and the second support through bearings. One end of the support shaft extends out of the second support and is fixedly connected to one end of the connecting plate. The other end of the connecting plate is rotatably connected to the connecting piece through a rotating shaft. A bushing is sleeved and connected to the outside of the support shaft. The support shaft and the bushing are connected by a pin. The baffle is located above the baffle bar of the normalizing furnace and is fixedly connected to the bushing. The connecting piece is fixedly connected to the piston rod of the cylinder, and the tail of the cylinder is rotatably connected to the third support.

[0005] Preferably, a tapered sleeve is fixedly connected to the connecting plate by bolts, a clamping sleeve is fitted outside the tapered sleeve and fixedly connected to the tapered sleeve by bolts, the tapered sleeve is fitted outside the support shaft, and the tapered sleeve and the clamping sleeve together fix the support shaft and the connecting plate together.

[0006] Preferably, the tapered sleeve includes a flange portion and a tapered cylinder portion. The flange portion is fixedly connected to the connecting plate by bolts, and the outer circle of the tapered cylinder portion is conical, while the inner circle is adapted to the support shaft.

[0007] Preferably, the conical section is evenly divided into at least three parts along the radial direction, with a gap between each two parts to form a conical claw-shaped structure.

[0008] Preferably, the inner circle of the clamping sleeve is a conical hole that matches the outer circle of the conical part of the conical sleeve.

[0009] Preferably, the diameter of the shaft hole of the connector is larger than the diameter of the rotating shaft, and a proximity switch is provided at the end near the connecting plate.

[0010] The beneficial effects of adopting the above technical solution are as follows: This utility model has a simple structure, is easy to assemble and disassemble, is highly practical, is resistant to high temperature and impact, and has stable transmission. It can effectively solve the problem of material jamming and furnace shutdown caused by irregular arrangement of shafts during the material feeding process, effectively improving production efficiency and reducing equipment maintenance costs.

[0011] The support shaft of this utility model is fitted with a connecting bushing, and the baffle is welded to the bushing. The bushing and the support shaft are connected by a pin. When disassembling, simply remove the pin and then pull the support shaft out of the bushing. Disassembly and maintenance are particularly convenient.

[0012] The present invention provides a tapered sleeve and a clamping sleeve between the support shaft and the connecting plate. The tapered part of the tapered sleeve has a tapered claw structure. The clamping sleeve is fitted outside the tapered part. By cooperating with the tapered surface of the tapered part, the tapered part tightly hugs the support shaft, thus fixing the support shaft and the connecting plate together. This replaces the conventional key connection method, making disassembly and assembly convenient, the connection firm, and the power transmission stable and reliable.

[0013] This utility model is equipped with a proximity switch, and the diameter of the rotating shaft is smaller than the diameter of the shaft hole of the connecting piece. By utilizing the gap between the rotating shaft and the shaft hole, the connecting plate can rotate at a small angle to cut off the proximity switch and control the extension and retraction of the cylinder. This design concept and structure are both ingenious and simple. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] like Figure 1-2 As shown, the material handling device includes a clamping sleeve 1, a conical sleeve 2, a connecting plate 3, a support shaft 4, a first support 6, a second support 7, a baffle 8, a cylinder 9, a third support 10, a proximity switch 11, a rotating shaft 12, a connecting piece 13, and a bushing 14. The first support 6 and the second support 7 are fixedly connected to the outer walls of the normalizing furnace on both sides. The support shaft 4 passes through the normalizing furnace 5, and its two ends are rotatably connected to the first support 6 and the second support 7 via bearings. One end of the support shaft 4 extends out of the second support 7 and then passes through the connecting plate 3 and the conical sleeve 2 in sequence. The flange of the conical sleeve 2 is fixedly connected to one end of the connecting plate 3 by bolts. The other end of the connecting plate 3 is rotatably connected to the connecting piece 13 via the rotating shaft 12. The connecting piece 13 is fixedly connected to the piston rod of the cylinder 9, and the tail of the cylinder 9 is rotatably connected to the third support 10.

[0017] The conical part of the tapered sleeve 2 is evenly divided into four sections, with a gap between each pair of sections, forming a conical claw structure. The outer circle of the conical part is conical, and the inner circle is a circular hole. The inner circle of the clamping sleeve 3 is conical. The support shaft 4 is fitted inside the tapered sleeve 2, and the clamping sleeve 3 is fitted outside the conical part. Bolts fix the clamping sleeve 3 to the flange of the tapered sleeve 2. The tighter the bolts are tightened, the closer the clamping sleeve 3 is to the flange, the smaller the gap between the sections of the conical part, the smaller the inner circle of the conical part is compressed, and the tighter the conical part is gripped by the support shaft 4. The tightening force of the bolts should be such that the support shaft 4 and the tapered sleeve 2 do not rotate relative to each other.

[0018] For ease of disassembly and maintenance, a bushing 14 is fitted over the support shaft 4, and the support shaft 4 and bushing 14 are connected by a pin. The baffle 8 is located above the baffle 51 at the bottom of the furnace and is fixedly connected to the bushing 14.

[0019] The normalizing furnace body is divided into three parts, with a height difference between adjacent parts. When a shaft falls from one part into another, the irregularly shaped shaft impacts the baffle 8 and falls parallel to the baffle 8 onto the conveyor belt of the other part, where it is stopped by the baffle 8 and the guide strip 51 on the conveyor belt, thus adjusting its posture. When the shaft impacts the baffle 8, the baffle 8 causes the support shaft 4 to rotate a small angle, which in turn causes the connecting plate 3 to rotate a small angle. A proximity switch 11 is located near the end of the connecting plate 3. When the connecting plate 3 rotates a small angle, the proximity switch 11 is disconnected. Upon receiving the signal from the proximity switch 11, the cylinder 9 is controlled by the PLC control module to extend the piston rod of the cylinder 9, causing the connecting plate 3 and the support shaft 4 to rotate. The support shaft 4 then causes the baffle 8 to rotate, and the shaft stopped by the baffle 8 falls into the next part of the furnace with the same posture. Subsequently, the piston rod of cylinder 9 retracts, the baffle 8 and connecting plate 3 return to their original positions, and the proximity switch 11 is in the connected state, waiting for the next shaft to strike the baffle 8. It should be noted that, as... Figure 3 As shown, the diameter of the shaft hole of the connecting piece 13 must be larger than the diameter of the rotating shaft 12 to meet the condition of small-angle rotation of the connecting plate 3. When the connecting plate 3 rotates at a small angle, it will not affect the cylinder 9.

[0020] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
