Description

Technical Field

[0001] This utility model relates to the technical field of lifting tools for forging steel production lines, and specifically to a heat treatment combined anti-detachment lifting tool. Background Technology

[0002] Currently, domestic automated production lines for forged steel blanks are highly flexible, and most can flexibly switch between production of crankshaft or connecting rod blanks within their production capacity by changing forging dies and heat treatment hangers. Furthermore, an increasing number of blank manufacturers are adopting a "forging line + continuous through-line heat treatment" layout and production method. In addition, due to the high quality requirements of crankshaft and connecting rod blanks, suspended heat treatment is mostly used, which offers high heat treatment efficiency and high product quality reliability.

[0003] The so-called suspended heat treatment refers to the process of suspending the heat treatment load hanger on an automated production line through mechanical assembly. After the blank forging is completed, a robot loads the crankshaft or connecting rod blank onto the heat treatment hanger. Then, the electronic control system controls the suspension chain to rotate downwards, transporting the hanger and the workpiece blank placed on the hanger.

[0004] However, currently, during the overhead conveyor's movement, due to production pauses or workstation stoppages, the lifting device sways due to inertia, easily causing the blanks to frequently sway in the same direction and fall off. Workers need to spend time and manpower to put the fallen blanks back in place, and the blanks may be damaged due to the fall, resulting in unnecessary economic and quality losses, safety hazards, and reduced production efficiency. Existing suspended heat treatment lifting devices have poor flexibility, making changeovers laborious, time-consuming, and have long changeover cycles. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a heat treatment suspension hanger that is universal for connecting rods and crankshaft blanks and prevents them from falling off. This reduces the cost of heat treatment hangers and the frequency of production changes, while also preventing the blanks from falling off due to unidirectional swaying caused by pauses in the cycle or workstation stops during travel. The technical solution is as follows:

[0006] A heat treatment combined anti-detachment lifting device includes a lifting ring and a rectangular main frame. The lifting ring is fixed to the top of the rectangular main frame. A set of material feeding mechanisms is provided above and below the rectangular main frame, and the two sets of material feeding mechanisms are symmetrically arranged. Each material feeding mechanism includes two first material feeding plates and two second material feeding plates. The two first material feeding plates are respectively fixed to both sides of one side plate of the rectangular main frame and are symmetrically distributed. The two second material feeding plates are respectively fixed to both sides of the other side plate of the rectangular main frame and are symmetrically distributed. The first material feeding plates and second material feeding plates on the same side are symmetrically distributed. A first material supporting rod and a second material supporting rod are fixed between the first material feeding plates and the second material feeding plates on the same side. The first material supporting rod is located at the bottom of the first material feeding plates and the second material feeding plates, and the second material supporting rod is located on the top side of the first material feeding plates and the second material feeding plates away from the rectangular main frame.

[0007] A connecting rod hanging plate is fixed in the middle of the rectangular main frame. The top of the connecting rod hanging plate is provided with two symmetrically distributed rectangular hanging ports, which are located on both sides of the rectangular main frame.

[0008] Preferably, the top of both the first and second material placement plates is provided with arc-shaped grooves, and the four arc-shaped grooves are symmetrically distributed in pairs.

[0009] Preferably, both the first and second material placement plates are inverted right-angled trapezoids, and the hypotenuses of both the first and second material placement plates are located on the side of the material placement plate away from the rectangular main frame.

[0010] Preferably, support rods are fixed at the top, middle and bottom of the rectangular main frame. The three support rods are, from top to bottom, the first support rod, the second support rod and the third support rod. The two ends of the support rods are respectively fixedly connected to the two side plates of the rectangular main frame.

[0011] Preferably, two reinforcing rods are fixed between the first support rod and the second support rod. The two reinforcing rods are located on both sides of the connecting rod plate, and the two reinforcing rods and the first support rod form an inverted triangle.

[0012] Preferably, a base rod is fixed between the two reinforcing rods, and the base rod passes through the connecting rod plate and is fixed to the connecting rod plate.

[0013] Preferably, a vertical support rod is fixed between the second support rod and the third support rod.

[0014] Preferably, the lifting ring is in the shape of an isosceles triangle, with the apex of the ring being arc-shaped.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model includes a material placement plate and a support rod, which together form a feeding mechanism for placing crankshaft blanks. When the crankshaft blank is placed, its two ends are positioned in the arc-shaped grooves on the material placement plate, while the portion with the balance iron is located between the first and second material placement plates. The first and second material placement plates provide axial restraint for the crankshaft blank, while the second support rod and the rectangular main frame provide radial restraint. The first support rod provides support for the crankshaft blank. The material placement plate and support rod provide multi-directional restraint for the crankshaft blank, effectively preventing the blank from falling off due to shaking or sudden stopping of the lifting device, thus improving the anti-detachment effect of the lifting device.

[0017] Meanwhile, this utility model also includes a connecting rod hanging plate for hanging connecting rod blanks, enabling the simultaneous placement of crankshaft blanks and connecting rod blanks, thus improving the versatility of the lifting tool. Furthermore, the rectangular hanging opening on the connecting rod hanging plate significantly reduces the possibility of the connecting rod blank falling off.

[0018] This utility model has a simple and reliable structure, low manufacturing cost, good anti-detachment effect, and is easy and convenient to use. It is conducive to improving the timeliness and efficiency of heat treatment and reducing the production cycle. Attached Figure Description

[0025] Combined with appendix Figure 1 -Appendix Figure 3 A heat treatment assembly anti-detachment lifting device includes a lifting ring 1 and a rectangular main frame 15. The lifting ring 1 is fixed to the top of the rectangular main frame 15. The lifting ring 1 is in the shape of an isosceles triangle, with an arc-shaped apex. The shape of the lifting ring 1 facilitates the lifting of the device, thereby facilitating its removal and replacement, and improving the efficiency of heat treatment production changeover. The triangular design of the lifting ring 1 also enhances its structural stability and strength.

[0026] The rectangular main frame 15 is made of heat-resistant steel. A set of feeding mechanisms is provided above and below the rectangular main frame 15, and the two sets of feeding mechanisms are symmetrically arranged. The feeding mechanism includes two first feeding plates 2 and two second feeding plates 3. The two first feeding plates 2 are respectively fixed to both sides of one side plate of the rectangular main frame 15, and the two first feeding plates 2 are symmetrically distributed. The two second feeding plates 3 are respectively fixed to both sides of the other side plate of the rectangular main frame 15, and the two second feeding plates 3 are symmetrically distributed. The first feeding plates 2 and the second feeding plates 3 on the same side are symmetrically distributed. A first supporting rod 12 and a second supporting rod 13 are fixed between the first feeding plates 2 and the second feeding plates 3 on the same side. The first supporting rod 12 is located at the bottom of the first feeding plates 2 and the second feeding plates 3, and the second supporting rod 13 is located at the top of the first feeding plates 2 and the second feeding plates 3 on the side away from the rectangular main frame 15.

[0027] A connecting rod hanging plate 10 is fixed in the middle of the rectangular main frame 15. The top of the connecting rod hanging plate 10 has two symmetrically distributed rectangular hanging openings 11, located on opposite sides of the rectangular main frame 15. In use, the connecting rod blank is suspended by engaging the holes at either the large or small end of the connecting rod with the rectangular hanging openings 11. Specifically, after the connecting rod blank is hung in the rectangular hanging opening 11, the end face of the connecting rod blank at one end of the rectangular hanging opening 11 is lower than the top surface of the rectangular hanging opening 11, further preventing the connecting rod blank from falling off during travel. More specifically, the length of the bottom edge of the rectangular hanging opening 11 is greater than the thickness of the connecting rod blank.

[0028] The top of the first material plate 2 and the second material plate 3 are provided with arc-shaped grooves 4. The four arc-shaped grooves 4 are symmetrically distributed in pairs. The arc-shaped grooves 4 are used to support the end of the crankshaft blank and play a role in preventing it from falling off and positioning it.

[0029] Specifically, both the first material placement plate 2 and the second material placement plate 3 are inverted right-angled trapezoids, and the hypotenuses of the first material placement plate 2 and the second material placement plate 3 are located on the side of the material placement plate away from the rectangular main frame 15.

[0030] Specifically, support rods are fixed at the top, middle, and bottom of the rectangular main frame 15. The three support rods, from top to bottom, are the first support rod 5, the second support rod 6, and the third support rod 7. The two ends of each support rod are fixedly connected to the two side plates of the rectangular main frame 15. A vertical support rod 14 is fixed between the second support rod 6 and the third support rod 7. The first support rod 5, the second support rod 6, the third support rod 7, and the vertical support rod 14 enhance the strength of the rectangular main frame 15, increasing the load-bearing capacity of the lifting device and thus increasing the number and weight of blanks that the lifting device can hold.

[0031] Specifically, two reinforcing rods 8 are fixed between the first support rod 5 and the second support rod 6. The two reinforcing rods 8 are located on both sides of the connecting rod hanging plate 10. The two reinforcing rods 8 and the first support rod 5 form an inverted triangle, forming a triangular reinforcement structure, which improves the overall rigidity of the lifting device.

[0032] Specifically, a base rod 9 is fixed between the two reinforcing rods 8, and the base rod 9 passes through the connecting rod mounting plate 10 and is fixed to the connecting rod mounting plate 10. The base rod 9 further improves the structural strength of the connecting rod mounting plate 10.

[0033] In use, the shaft portions at both ends of the crankshaft blank are placed in the arc-shaped grooves 4 on the placement plate, with the portion containing the balance iron located between the first placement plate 2 and the second placement plate 3. The connecting rod is then hung on the connecting rod hanging plate 10 through the fit between the hole at its end and the rectangular hanging port 11. During travel, the lifting device travels in the axial direction of the crankshaft blank placed on it.
