Description

Technical Field

[0001] The utility model belongs to the technical field of heat treatment of steering knuckles, in particular to a movable hanger and a material rack for a steering knuckle heat treatment furnace using the movable hanger. Background Art

[0002] At present, automobile steering knuckles are mainly made of aluminum alloy, and casting occupies a major position. In the processing and manufacturing process of cast aluminum alloy automobile steering knuckles, heat treatment is a very important step, which directly determines the mechanical properties and internal structure of aluminum alloy automobile steering knuckles.

[0003] For example, a Chinese patent (authorization publication number CN 206308390 U) discloses a material rack for a continuous furnace for casting aluminum steering knuckles, which includes a basic support frame with several layers of load-bearing base plates arranged horizontally. The adjacent load-bearing base plates are grouped in pairs. Based on the shape of the part, at least three support tubes are welded on each group of load-bearing base plates, which are distributed at predetermined angles and are centered on the load-bearing base plate and extend to both sides thereof.

[0004] However, due to the high temperature in the furnace, the linear support tube of the above-mentioned prior art is prone to softening during the high-temperature heat treatment process at 510℃~550℃. Coupled with the weight of the steering knuckle, the support tube will undergo a large degree of linear deformation, which will cause the steering knuckle to be unable to be stably suspended on the support tube and may slip off the support tube, making the heat treatment quality of the steering knuckle very unstable. In addition, the deformed support tube will affect subsequent use and cause the material rack to be scrapped. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a movable hanger and a material rack for a steering knuckle heat treatment furnace using the movable hanger. By detachably mounting the movable hanger on the material rack, the direction of the movable hanger can be changed at any time after being deformed during use, thereby avoiding the material rack from being scrapped, prolonging its service life, and avoiding waste of costs.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A movable hanger comprises a rod body and a hook body, wherein the hook body has a connecting plate, one end of the rod body is perpendicularly arranged on the outer wall of the connecting plate, and both sides of the inner wall of the connecting plate are extended outwardly to form hanging plates with a symmetrical structure;

[0008] Two mirror-image hooks are provided in the middle of the outer side of the hanging plate, with a certain distance between the two hooks. A semicircular arc groove is formed between the inner wall of the hook and the hanging plate, and two concave arc grooves in a mirror-image structure are provided at the upper and lower ends of the outer side of the hanging plate.

[0009] The present utility model also provides a material rack for a steering knuckle heat treatment furnace, comprising a frame and the movable hanger as described above, wherein at least one of the front and rear vertical surfaces of the frame is provided with a plurality of transverse support rods arranged in a parallel and spaced array, and the movable hanger can be movably coordinated with two adjacent upper and lower transverse support rods, wherein the upper transverse support rod is clamped in the semicircular arc groove on the upper part of the movable hanger, and the lower transverse support rod is abutted and fitted with the concave arc groove on the lower part of the movable hanger; when the movable hanger is coordinated with the frame, the rod can be tilted upward.

[0010] In one embodiment, the distance between the center of the semicircular groove and the connecting plate is smaller than the distance between the center of the inwardly concave groove and the connecting plate. This ensures that the other end of the rod is tilted upward. Similarly, if the distance between the center of the semicircular groove and the connecting plate is larger than the distance between the center of the inwardly concave groove and the connecting plate, the other end of the rod will droop downward.

[0011] The angle of the rod body is 5 degrees. The movable hanger is specially designed to be tilted 5 degrees when installed on the frame so that the steering knuckle can be stably suspended on the rod body when the material rack is fed into the furnace to prevent the steering knuckle from slipping off the rod body.

[0012] In one embodiment, the movable hook has a plurality of through-holes spaced evenly apart at the rear end of the rod. Steel rods or wire ropes can be inserted into the through-holes to act as a stopper and prevent the steering knuckle from slipping off the end of the rod when the rod deforms, ensuring that the steering knuckle remains suspended on the rod. The multiple through-holes can be adapted to the number of steering knuckles suspended on the rod, and the through-hole position for the stopper can be selected based on the number of steering knuckles.

[0013] In one embodiment, the movable hook comprises a welded connection between the rod and the connecting plate. Because the rod bears the entire weight of the steering knuckle, the connection between the rod and the hook must be extremely strong and stable. Welding allows the hook and rod to form a single, integrated unit, providing high strength and stability, thus enabling them to withstand significant loads and pressure.

[0014] In one embodiment, the frame includes a base, a fixing frame, and a fence plate. The fixing frame is welded vertically to the center of the base, and the fence plate is mounted within the fixing frame. The fence plate is provided with a plurality of transverse support rods arranged in a parallel array and a plurality of vertical support plates arranged in a parallel array. The transverse support rods pass through the vertical support plates. The vertical support plates provide a certain degree of support for the transverse support rods, preventing deformation of the transverse support rods that could cause instability in the mounting of the movable hanger thereon.

[0015] The base comprises a plurality of square steel pieces welded and fixed in a crisscross pattern, with a plurality of drainage holes evenly arranged on the bottom of the square steel pieces to quickly drain away water accumulated in the quenching station.

[0016] The fixing frame includes four longitudinal channel steels and two transverse channel steels, and reinforcement ribs are welded and fixed on the outer sides of adjacent longitudinal channel steels and between transverse channel steels and longitudinal channel steels. The reinforcement ribs are added to prevent deformation of the fixing frame during heat treatment.

[0017] An inclined support reinforcement rod is provided between the fixing frame and the base, a vertical extension rod is provided on the support reinforcement rod, and a horizontal extension rod is provided on the fixing frame, and the horizontal extension rod is fixedly connected to the vertical extension rod to ensure the stability of the connection between the fixing frame and the base.

[0018] Compared with the prior art, the advantages of the present invention are: the structure is simple and the cost is low; by hanging the movable hanger on the adjacent transverse support rods of the frame, the transverse support rods at the top are clamped in the semicircular arc groove of the upper part of the movable hanger, and the transverse support rods at the bottom are abutted and fitted with the concave arc groove of the lower part of the movable hanger. Finally, when the movable hanger is matched with the frame, the rod body of the movable hanger can be tilted upward, and the hanging position of the movable hanger can be adjusted automatically, which is very flexible and convenient; when the movable hanger is deformed during use, it only needs to be turned 180 degrees in one direction, so that the deformed downward direction is changed to the upward direction and it can be used again, thereby achieving the purpose of being able to replace the rod body at any time after use, improving the service life of the material rack and avoiding waste.

DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive and should not limit the scope of protection of the present invention.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] Example 1:

[0029] like Figure 1 As shown, this embodiment proposes a movable hanger 1, a rod body 10 and a hook body 11, the hook body 11 has a connecting plate 111, one end of the rod body 10 is perpendicularly arranged on the outer wall of the connecting plate 111, and hanging plates 112 with a symmetrical structure are extended outward on both sides of the inner wall of the connecting plate 111; two hook parts 113 with a mirror structure are arranged in the middle position of the outer side of the hanging plate 112, and there is a certain distance between the two hook parts 113, and a semicircular arc groove 114 is formed between the inner wall of the hook part 113 and the hanging plate 112, and two concave arc grooves 115 with a mirror structure are arranged at the upper and lower ends of the outer side of the hanging plate 112.

[0030] The movable hanger can be detachably mounted on two cylindrical shafts. It is sufficient to ensure that the upper cylindrical shaft is clamped in the semicircular arc groove on the upper part of the movable hanger and the lower cylindrical shaft is abutted and fitted with the concave arc groove on the lower part of the movable hanger. The movable hanger can also be rotated 180 degrees and installed and used in the same manner. It is very flexible and convenient. Workpieces such as automobile steering knuckles can be suspended on the rod body of the movable hanger.

[0031] Example 2:

[0032] like Figures 2 to 5 As shown, this embodiment provides a material rack for a steering knuckle heat treatment furnace, comprising a frame 2 and a movable hanger 1 as described in Example 1, wherein at least one of the front and rear vertical surfaces of the frame 2 is provided with a plurality of parallel and spaced array-arranged transverse support rods 231 from top to bottom, and the movable hanger 1 can be movably matched with the two adjacent upper and lower transverse support rods 231, wherein the upper transverse support rod 231 is stuck in the semicircular arc groove 114 on the upper part of the movable hanger 1, and the lower transverse support rod 231 is abutted and fitted with the concave arc groove 115 on the lower part of the movable hanger 1; when the movable hanger 1 is matched with the frame 2, the rod 10 can be tilted upward.

[0033] By hanging the movable hanger 1 on the adjacent transverse support rod 231 of the frame 2, the transverse support rod 231 at the top is stuck in the semicircular arc groove 114 on the upper part of the movable hanger 1, and the transverse support rod 231 at the bottom is abutted and fitted with the concave arc groove 115 at the lower part of the movable hanger 1. Finally, when the movable hanger 1 is matched with the frame 2, the rod 10 of the movable hanger 1 can be tilted upward; when the movable hanger 1 is deformed during use, it only needs to be turned 1180° in one direction and hung on the transverse support rod 231 again, so that the direction that was originally deformed and drooping is changed to the upward direction and it can be used again, thereby achieving the purpose of being able to replace the rod at any time after use, thereby improving the service life of the material rack and avoiding waste.

[0034] The design that ensures that the rod 10 on the movable hook 1 can tilt upward after installation is that the distance between the center of the semicircular arc groove 114 and the connecting plate 111 is smaller than the distance between the center of the inwardly concave arc groove 115 and the connecting plate 111. This ensures that the other end of the rod can tilt upward. Similarly, if the distance between the center of the semicircular arc groove and the connecting plate is greater than the distance between the center of the inwardly concave arc groove and the connecting plate, the other end of the rod will droop downward.

[0035] After the movable hanger 1 is installed, the rod 10 tilts up at an angle of 5 degrees. The 5-degree tilt when the movable hanger is installed on the frame is specially designed so that the steering knuckle can be stably suspended on the rod when the material rack is fed into the furnace, preventing the steering knuckle from slipping off the rod.

[0036] In this embodiment, the movable hook 1 has a plurality of through-holes 101 spaced evenly apart at the rear end of the rod 10. The rod is a solid round bar with a diameter of 20 mm. The four through-holes are arranged 5 mm apart. Steel rods or wire ropes can be inserted into these through-holes to act as a stopper, preventing the steering knuckle from slipping off the end of the rod when the rod deforms, ensuring that the steering knuckle remains suspended from the rod. The multiple through-holes allow for the selection of the through-holes for the stopper based on the number of knuckles to be mounted on the rod.

[0037] In this embodiment, the movable hook 1 is welded between the rod 10 and the connecting plate 111. Because the rod bears the entire weight of the steering knuckle, the connection between the rod and the hook must be very strong and stable. Welding allows the hook and rod to form a single unit, providing high strength and stability, allowing them to withstand heavy loads and pressure.

[0038] In this embodiment, the frame 2 includes a base 21, a fixing frame 22, and a fence plate 23. The fixing frame 22 is vertically mounted in the middle of the base 21 by welding, and the fence plate 23 is mounted within the fixing frame 22. The fence plate 23 is provided with 28 transverse support rods 231 arranged in a parallel array and 9 vertical support plates 232 arranged in a parallel array. The transverse support rods 231 horizontally pass through the vertical support plates 231. The vertical support plates provide a certain degree of support for the transverse support rods, preventing deformation of the transverse support rods that would otherwise cause instability in the installation of the movable hanger thereon.

[0039] The base 21 comprises a square steel member 211 welded together in a crisscross pattern, 10 longitudinally and 7 transversely. Drain holes 212 are evenly distributed across the bottom of the member. These holes allow for rapid drainage of water accumulated in the quenching station.

[0040] The fixing frame 22 includes four longitudinal channel steels 221 and two transverse channel steels 222. Reinforcement ribs 223 are welded to the outer sides of adjacent longitudinal channel steels 221 and between the transverse channel steels 222 and the longitudinal channel steels 221. The reinforcement ribs are added to prevent deformation of the fixing frame during heat treatment.

[0041] An inclined support reinforcement rod 24 is provided between the fixing frame 22 and the base 21. A vertical extension rod 25 is provided on the support reinforcement rod 24. A horizontal extension rod 26 is provided on the fixing frame 22 and is fixedly connected to the vertical extension rod 25. The coordinated action of the support reinforcement rod, the horizontal extension rod, and the vertical extension rod ensures the stability of the connection between the fixing frame and the base.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
