Description

Technical Field

[0001] The utility model relates to the technical field of quenching processing equipment, in particular to a large thin-walled ring-type workpiece quenching material tray. Background Art

[0002] Large thin-walled ring workpieces generally refer to ring workpieces with a diameter of more than 2m and a wall thickness of 50-300mm. Such workpieces are prone to deformation during quenching, and are not easy to lift and transport whether in hot or cold states, making quenching difficult.

[0003] Traditionally, thin-walled ring-type workpieces are quenched by passing a special quenching chain through the ring, and the entire ring is lifted and quenched. This method is simple and low-investment, but due to the structure of the parts, the workpiece will have severe elliptical deformation after quenching in this way. Multiple correction steps are required to ensure the deformation of the workpiece, resulting in high production costs and long cycles. If the correction amount is exceeded, the workpiece will be directly scrapped.

[0004] In order to solve the risk of deformation when using chains for direct quenching, high-temperature alloy cast round pallets are currently used, and special lifting fixtures are used for quenching. However, the structure of high-temperature alloy casting pallets is generally complex and bulky, and the clamping efficiency is not high. At the same time, the cost is high and the investment is large, resulting in high quenching costs and low clamping efficiency for large thin-walled ring workpieces. Utility Model Content

[0005] The utility model aims to provide a large thin-walled ring-like workpiece quenching material tray to solve the problems in the prior art that large thin-walled ring-like workpieces are easily deformed during quenching, increase production processes, are inconvenient to clamp and operate, and increase production costs.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model specifically provides a large thin-walled ring-type workpiece quenching material tray, including beam frames arranged on both sides, and a plurality of reinforcing tubes are arranged in parallel between the beam frames; the reinforcing tubes are square tubes with a length of 800-1200mm; the beam frame includes at least one I-beam, and a plurality of connecting tubes are arranged in parallel on the I-beam, one end of the connecting tube is connected to one end of the reinforcing tube; the length of the connecting tube is 150-300mm; a quenching chain is arranged on the periphery of the beam frame, and the upper end of the quenching chain is connected to a crane hook.

[0008] The principles and advantages of this solution are:

[0009] Since large thin-walled ring-like workpieces generally have a diameter of more than 2m and a wall thickness of 50-300mm, the workpieces are easily deformed during quenching due to the force of the clamping hanger, which requires additional correction processes, prolongs the production cycle, and also increases production costs. This solution adopts a beam frame 1 structure to lift the workpiece from the bottom, thereby avoiding the problem of deformation of the workpiece due to uneven force during the quenching process. The beam frame 1 structure can also meet the placement and support of workpieces of various specifications, thereby improving the versatility of the tray. At the same time, this solution adopts reinforcing pipes and connecting pipes, and by reasonably arranging their lengths and relative positions, the strength and hardness of the tray are improved, ensuring that the tray will not deform or crack during repeated hot and cold cycles, improving production safety, extending the service life of the tray, and effectively expanding its scope of use. At the same time, this solution has a simple structure, convenient and quick operation, low manufacturing cost, low difficulty in clamping operation, and greatly improves the efficiency of quenching processing.

[0013] The following is further described in detail through specific implementation methods:

[0014] The reference numerals in the drawings of the specification include: a crossbeam frame 1, a reinforcing pipe 2, an I-beam 3, a connecting pipe 4, a workpiece 5, a quenching chain 6, a crane hook 7, and a fixing ring 8.

[0015] This embodiment is basically as shown in the attached Figure 1 As shown: A large thin-walled ring-type workpiece quenching tray is made of rail steel and ordinary rectangular steel pipes, with low manufacturing cost. Due to the excellent structure of the rail steel, the structure of the reinforcing pipe and the connecting pipe is reasonably set to ensure that the tray will not deform or crack during repeated hot and cold cycles, ensuring production safety, and increasing service life and versatility. Figure 1As shown, it includes a crossbeam frame 1 arranged on both sides, and a plurality of reinforcing tubes 2 are welded in parallel between the crossbeam frames 1. In this embodiment, the reinforcing tube 2 is a square tube made of ordinary steel rectangular tube, and its transverse length is 800-1200mm, so that the distance between the crossbeam frames 1 on both sides is 800-1200mm, and the width of the reinforcing tube 2 is 100-150mm, so as to meet the placement and support of various specifications of workpieces in the width direction. In this embodiment, 3-7 reinforcing tubes 2 are set, and the distance between adjacent reinforcing tubes 2 is 80-400mm, so as to meet the strength of the reinforcing tube 2, and at the same time ensure the longitudinal length distance of the reinforcing tube 2 to match the length of the crossbeam frame 1. In this embodiment, the length of the crossbeam frame 1 is set to 1500-4000mm, so as to meet the support and placement of workpieces of various specifications in the length direction, and at the same time can be applied to the quenching device, which is convenient for holding the workpiece and facilitating the movement of the workpiece, ensuring simple and quick operation.

[0016] As attached Figure 2 As shown, the cross beam frame 1 includes at least one I-beam 3, and a plurality of connecting pipes 4 are welded in parallel on the I-beam 3, and the free end of the connecting pipe 4 is welded to one end of the reinforcing pipe 2, so that the I-beam 3 is welded to the reinforcing pipe 2. In this embodiment, the connecting pipe 4 is a common steel rectangular pipe structure, and the length of the connecting pipe 4 is set to 150-300mm and the width is 100-150mm to ensure the support strength of the cross beam frame 1, improve the hardness of the cross beam frame 1, and avoid deformation or cracking of the cross beam frame 1.

[0017] In this embodiment, the crossbeam frame 1 is welded by two I-beams 3 arranged side by side, and the adjacent I-beams 3 are connected by welded connecting pipes 4, and the connecting pipes 4 are set to 3-7. In this embodiment, the I-beam 3 is made of rail steel with a specification of 43Kg / m-60Kg / m, which ensures the hardness and strength of the I-beam 3 and prevents the material tray from deforming or cracking during repeated hot and cold cycles. In other embodiments, according to the weight of the workpiece 5, 1 or 3 I-beams 3 can be selected to form the crossbeam frame 1. The design structure is simple, the overall weight is light, the manufacturing cost is low, and it can be applied to the lifting of workpieces of various specifications, with higher versatility and effective improvement of quenching efficiency.

[0018] As attached Figure 3 As shown, a quenching chain 6 is also installed on the periphery of the crossbeam frame 1, and the upper end of the quenching chain 6 is connected to the crane hook 7. In this embodiment, two quenching chains 6 are provided, which are respectively wound around the two ends of the crossbeam frame 1, and the crossbeam frame 1 is fixed on the quenching chains 6 from both ends, so as to lift the crossbeam frame 1. In this embodiment, the quenching chain 6 is a special quenching chain, and the ends of the two quenching chains 6 are fixedly connected to the fixing ring 8, and are hung on the crane hook 7 through the fixing ring 8, so as to lift the quenching material tray and move it.

[0019] The specific implementation process is as follows:

[0020] As attached Figure 1 To Attachment Figure 3 As shown, the workpiece 5 is placed on the tray before quenching. During quenching, the special quenching chain 6 on the crane hook 7 is lowered, and the operator passes the lower ends of the two quenching chains 6 through the two ends of the crossbeam frame 1 respectively. After confirming that the crossbeam frame 1 is stably placed on the two quenching chains 6, the crane is operated to rise, and the tray is controlled to drive the workpiece to move, completing the workpiece quenching process. After quenching is completed, the crane is controlled to take out the workpiece.

[0021] In this embodiment, the crossbeam frame 1 is formed into a tray shape, and the workpiece 5 is lifted from the bottom, thereby ensuring the stability of the workpiece 5 during quenching, avoiding deformation of the workpiece, and thus eliminating multiple correction processes, ensuring the quality of the workpiece, improving the yield rate, and also reducing production costs and shortening the production cycle. At the same time, by providing a reinforcing tube 2 and a connecting tube 4, the stability and strength of the tray are improved, ensuring that the tray will not deform or crack during repeated hot and cold cycles, increasing the service life of the tray, and also ensuring production safety. This solution has a simple structure, low manufacturing cost, and convenient clamping and operation, which effectively improves operating efficiency, thereby improving quenching processing efficiency.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
