Description

Technical Field

[0001] The utility model relates to the technical field of quenching hoisting, in particular to a connecting rod quenching tooling. Background Art

[0002] Quenching is an important process in the forging process of connecting rods. To reduce the deformation of the connecting rods during quenching, the workpiece must be placed vertically into the quenching pool. Therefore, a reasonable quenching tooling can not only effectively ensure the deformation of the workpiece, but also improve the quenching efficiency.

[0003] Traditionally, generally single connecting rods are quenched. A holding clamp (similar to a vise in structure) is used to clamp one end of the connecting rod and lift it for quenching. When there are many connecting rods, the total quenching time is long and the production efficiency is low; the holding clamp and the connecting rod enter the quenching pool at the same time. The holding clamp is unevenly heated for a long time, and contacting with the quenching liquid results in high replacement and maintenance frequency and high cost; when taking out of the furnace, the working temperature is extremely high, up to more than 900 degrees, and the operation time of the operator is long, increasing the safety risk. Summary of the Utility Model

[0004] The utility model aims to provide a connecting rod quenching tooling to solve the technical problem of low quenching efficiency caused by the unreasonable structure of the existing connecting rod quenching tooling.

[0005] The basic scheme provided by the utility model is as follows: a connecting rod quenching tooling, comprising a lifting ring, a plurality of first ropes, a plurality of second ropes, a bracket, a plurality of multi-connecting rod mounting members and a plurality of limiting members; the lifting ring and the bracket are connected by a plurality of first ropes; the bracket and a plurality of limiting members are connected by a plurality of second ropes; at least two limiting members are connected to one multi-connecting rod mounting member, and at least one limiting member is movably connected to the multi-connecting rod mounting member; a plurality of the multi-connecting rod mounting members are symmetrically distributed under the bracket; there is a distance between adjacent limiting members mounted on the multi-connecting rod mounting member, and the distance is used for spacing and mounting a plurality of connecting rods.

[0006] The working principle and advantages of the utility model are as follows: Hang the lifting ring on the overhead crane hook, pass the multi-connecting rod mounting member through a plurality of connecting rods and at least two limiting members, and lift and send the whole into the quenching pool for quenching. The number of connecting rods mounted on each multi-connecting rod mounting member is the same and the positions are symmetrical. On the basis that the multi-connecting rod mounting members are symmetrically distributed under the bracket, the whole tooling remains balanced after lifting a plurality of connecting rods.

[0007] This tooling has a simple structure, can be reused, and the manufacturing and maintenance costs of the easily damaged contact components are low; by using this tooling, the number of quenched connecting rods in one batch is increased, batch quenching of connecting rods is achieved, the time used for quenching during batch production of connecting rods is reduced, and the energy consumption of the heat treatment furnace is lowered; the symmetric distribution structure of the multi-connecting rod mounting parts effectively improves the stability and safety during the quenching of connecting rods; it is convenient to operate, reducing the labor intensity of the operator and the safety risks due to working in a high-temperature environment for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic structural diagram of a connecting rod quenching tooling provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0009] The following will be further described in detail through specific embodiments:

[0010] The reference signs in the accompanying drawings of the specification include: lifting ring 1, connecting ring 2, first rope 3, second rope 4, bracket 5, cross bar 51, steel bar 6, limiting ring 7, connecting rod 8.

[0011] Embodiment 1

[0012] Basically as shown in the appendix Figure 1 shown: A connecting rod 8 quenching tooling includes a lifting ring 1, a plurality of first ropes 3, a plurality of second ropes 4, a bracket 5, a plurality of multi-connecting rod mounting parts and a plurality of limiting parts; it also includes a plurality of connecting rings 2.

[0013] The lifting ring 1 and the bracket 5 are connected by a plurality of first ropes 3; the lifting ring 1 is connected to the plurality of first ropes 3 through a plurality of connecting rings 2, and one connecting ring 2 is correspondingly connected to one first rope 3; the bracket 5 and the plurality of limiting parts are connected by a plurality of second ropes 4; at least two limiting parts are connected to one multi-connecting rod mounting part, and at least one limiting part is movably connected to the multi-connecting rod mounting part; the plurality of multi-connecting rod mounting parts are symmetrically distributed below the bracket 5; there is a spacing between adjacent limiting parts mounted on the multi-connecting rod mounting parts, and the spacing is used for installing a plurality of connecting rods 8 at intervals.

[0014] The connecting rod 8 has a large end and a small end, and the small end has a mounting hole. The connecting rod 8 is installed on the multi-connecting rod mounting part by passing the mounting hole through the multi-connecting rod mounting part, and the cross-sectional dimension of the multi-connecting rod mounting part that fits through the mounting hole is adapted to the size of the mounting hole.

[0015] In this embodiment, the bracket 5 includes two cross bars 51 and two vertical bars. Among them, the two cross bars 51 are parallel, and the two vertical bars are symmetrically installed between the two cross bars 51 and perpendicular to the two cross bars 51 to ensure the balance of the bracket 5 itself. The length of the cross bar 51 is 2500 mm, the diameter is 30 mm, the length of the vertical bar is 1000 mm, the diameter is 20 mm, and the material is 40CrNiMo steel, which has effects such as high temperature resistance, corrosion resistance, and anti-deformation.

[0016] There are 4 connecting rings 2, with a diameter of 30 - 20 mm (outer diameter - inner diameter); there are 4 first ropes 3, with a length of 2000 mm, and 4 second ropes 4, with a length of 2000 mm. Both the first rope 3 and the second rope 4 are steel wires, and the model can be a steel wire with a diameter of 10 mm. The setting of the lengths of the two ropes can ensure that the height of the workpiece placed in the quenching furnace meets the quenching requirements; there are 2 multi-link mounting parts, and the structure of the multi-link mounting part is a strip structure, which can be a steel bar 6, with a length of 3000 mm and a diameter of 30 mm; there are 4 limit parts, and the limit parts are limit rings 7, with a diameter of 45 - 32 mm (outer diameter - inner diameter), which is adapted to the diameter of the steel bar 6, and the diameter difference is 2 - 15 mm, facilitating the perforated movable connection with the steel bar 6. Since the steel bar 6 is used to hang the connecting rod 8, after long-term use, friction occurs between the steel bar 6 and the connecting rod 8, which will cause damage to the steel bar 6. Therefore, the perforated movable connection makes the replacement and maintenance of the steel bar 6 convenient in the later stage.

[0017] Above each end of each cross bar 51, a first rope 3 is connected, and below each end, a second rope 4 is connected. To ensure strength and durability, the two ends of the cross bar 51 and the ropes (steel wires) are connected together by welding, and all the welding points are reasonably distributed to ensure that the bracket 5 remains balanced and the force is reasonable when the crane lifts the entire workpiece; in other embodiments, the number of the first ropes 3 can be increased, connected to the middle or other positions of the cross bar 51, reducing the force on each first rope 3 and strengthening the balance stability of the bracket 5; the number of the second ropes 4 can be increased, reducing the force on each second rope 4 and strengthening the stability of the steel bar 6. The number of the first ropes 3 and the number of the second ropes 4 can be different, respectively meeting the different stability requirements of the bracket 5 and the steel bar 6.

[0018] At the other end of each second rope 4 away from the cross bar 51, a limit ring 7 is connected; 4 second ropes 4 correspond to 4 limit rings 7; there are two limit rings 7 below each cross bar 51, and a steel bar 6 passes through between the two limit rings 7. The distance between the two limit rings 7 on the steel bar 6 is limited by the welding position of the two second ropes 4 on the cross bar 51. Therefore, the welding position of the second rope 4 on the cross bar 51 not only needs to ensure the balance and stability of the steel bar 6 but also ensure that the distance between the two limit rings 7 on the steel bar 6 meets the placement space of multiple connecting rods 8.

[0019] In other embodiments, the first rope 3 and the second rope 4 are an integral rope; both ends of the two cross bars 51 are welded to the preset positions of 4 integral ropes. The length of the integral rope is 4000 mm, and the preset positions are at 2000 mm. Similarly, all welding points need to ensure the overall balance of the bracket 5.

[0020] The main specific usage process is as follows:

[0021] Hang the lifting ring 1 on the overhead crane hook. After lifting, the bracket 5 is in a balanced suspended state. The limit ring 7 and the small end mounting hole of the connecting rod 8 are at the same height. Pass the steel rod 6 through the two limit rings 7 and several small end mounting holes of the connecting rods 8. The connecting rods 8 are arranged in the same way during furnace loading, and the small end mounting holes are on the same horizontal line. Generally, one can first pass through one limit ring 7, then sequentially pass through several small end mounting holes of the connecting rods 8, adjust the position of each connecting rod 8, and finally pass through another limit ring 7; the number of connecting rods 8 installed on the two steel rods 6 is the same, and the position of the connecting rods 8 on the other steel rod 6 is adjusted correspondingly according to the position of the connecting rods 8 on the previous steel rod 6, so that after the entire tooling lifts several connecting rods 8, the lifting will send the whole into the quenching pool for quenching, and the whole remains balanced. The number of connecting rods 8 that each steel rod 6 can hang is ≤10, and the spacing is 50 mm. While ensuring the batch quenching of the connecting rods 8, it ensures that the overall weight of the tooling and multiple connecting rods 8 is reasonable, and the spacing meets the requirements for single connecting rod 8 quenching.

[0022] A connecting rod quenching tooling provided by this embodiment has a simple structure, can be reused, and the manufacturing and maintenance costs of easily damaged contact parts such as steel rods are low; using this tooling, the number of connecting rods quenched at one time is increased, batch quenching of connecting rods is realized, the time used for quenching during batch production of connecting rods is reduced, and the energy consumption of the heat treatment furnace is reduced; the symmetric distribution structure of the multi-connecting rod mounting parts effectively improves the stability and safety during connecting rod quenching; it is convenient to operate, reduces the labor intensity of the operator and the safety risk of working in a high-temperature environment for a long time.

[0023] Embodiment Two

[0024] Different from Embodiment One, a plurality of limit grooves are opened on the multi-connecting rod mounting part. The position of each limit groove is correspondingly set according to the position of the limit piece, the number of connectable connecting rods, and the hanging spacing requirements, so that the limit groove limits the corresponding limit piece and connecting rod, ensuring that during the lifting and moving process and the quenching process, the limit piece and the connecting rod never shift, ensuring the balance and stability of the tooling and the connecting rod, guaranteeing the quenching quality. At the same time, the setting of the limit groove can also improve the installation efficiency of the connecting rod and the limit piece, enabling the connecting rods on both sides to quickly reach balance, avoiding adjustment, improving the installation efficiency and the overall balance and stability of the tooling and the connecting rod, and ensuring the safety of connecting rod quenching.
