Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal hot processing equipment, in particular to a spring heat treatment rack. BACKGROUND

[0002] The spring is a widely used component, and in the spring production process, the spring needs to be subjected to high-temperature heat treatment so as to have better elasticity and toughness. When heat treatment is performed, a plurality of springs are usually placed on a heat treatment rack, and the heat treatment rack is placed into a heat treatment equipment, so that the springs are in a predetermined high-temperature environment, and the microstructure of the metal material for making the springs is changed to complete strengthening.

[0003] The existing heat treatment rack is made of a tray, and the tray is made of a metal material with good heat resistance. A user places a plurality of springs into the tray, so that the springs can be neatly stacked and placed into the heat treatment equipment.

[0004] The related technical solutions in the above have the following defects: when a plurality of springs are placed in the tray, the side of the spring in contact with the bottom of the tray exchanges heat with hot air in a small amount, resulting in uneven heating of the spring and poor heat treatment effect. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the uniformity of heat treatment on the spring, the present application provides a spring heat treatment rack.

[0006] The spring heat treatment rack provided by the present application adopts the following technical solutions:

[0007] A spring heat treatment rack comprises a base, a support column and a bracket. The base and the bracket are arranged in parallel, and the support column is arranged between the base and the bracket. One end of the support column is fixed to the base, and the other end is fixed to the bracket. A plurality of air holes are formed in the bracket, and the air holes penetrate the bracket.

[0008] By adopting the above technical solutions, the bracket is arranged on the base, and the bracket is supported by the support column, so that a gap is formed between the base and the bracket. When the bracket is placed with springs, the user places the heat treatment rack into the heat treatment equipment, so that the hot air flow can flow through the air holes, and the surface of the side of the spring in contact with the bracket can exchange heat with the hot air flow, so that the overall temperature of the spring is uniform, and the effect of improving the uniformity of heat treatment on the surface of the spring is achieved.

[0009] Optionally, one end of the support column away from the base is fixed with a cross beam, a plurality of cross beams are spliced to form a frame structure, the bracket is clamped in the frame structure surrounded by the cross beams, a plurality of support rods are connected to the cross beam, the length direction of the support rod is perpendicular to the support column, one end of the support rod is fixed to the base, and the other end is fixed to the cross beam.

[0010] By adopting the above technical solution, a crossbeam is set on the support column to form a frame structure, which allows the bracket to be locked in the frame formed by the crossbeam. This makes the bracket and the support column detachable and facilitates the user to move the spring in the bracket.

[0011] Optionally, the bracket is provided with a placement groove, and multiple locking pins are provided in the placement groove for fixing the spring.

[0012] By adopting the above technical solution, a placement groove is opened on the bracket, allowing the spring to be placed in the placement groove. A locking pin is set on the inner wall of the placement groove, allowing the spring to be sleeved on the locking pin. This keeps the spring in a stable position in the placement groove. When the heat treatment rack is placed in the heat treatment equipment, the probability of adjacent springs contacting each other is reduced, resulting in higher heat treatment quality of the spring surface.

[0013] Optionally, the locking pins are horizontally arranged, with multiple locking pins respectively arranged on opposite side walls within the placement slot.

[0014] By adopting the above technical solution, and by setting a locking pin horizontally in the bracket, when the spring is horizontally placed in the placement groove, both ends of the spring can be locked onto the locking pin respectively, thereby keeping the spring in a stable position in the placement groove.

[0015] Optionally, the locking pin is vertically positioned at the bottom of the placement slot.

[0016] By adopting the above technical solution, and by vertically setting the locking pin in the placement slot, the user can vertically sleeve the spring on the locking pin, thereby allowing multiple springs to be vertically placed in the bracket.

[0017] Optionally, the vent holes are arranged at equal intervals along the circumference of the locking pin.

[0018] By adopting the above technical solution, multiple vent holes are opened around the circumference of the locking pin. When hot air flows in the vent holes, gas flows through all the vent holes. When the spring is sleeved on the locking pin, the heating of each part of the spring can be uniform.

[0019] Optionally, the bracket is provided with an adjustment mechanism, which includes a screw, a handwheel and a guide rod. The screw is parallel to the length direction of the support column, passes through the bracket and is threadedly connected to the bracket. One end of the screw is rotatably connected to the base, and the other end is connected to the handwheel.

[0020] By adopting the above technical solution, an adjustment mechanism is set on the bracket, allowing the screw to pass through the bracket. The user can rotate the handwheel to make the screw rotate relative to the bracket. The guide rod locks the bracket and limits its position, allowing the bracket to be raised and lowered vertically. This facilitates the adjustment of the bracket height and allows the bracket to be placed in heat treatment equipment of different sizes.

[0021] Optionally, a ventilation mechanism is provided at the bottom of the bracket. The ventilation mechanism includes a fan hood and a duct. The fan hood is configured as an organ pipe, with one end of the organ pipe fixed to the bracket and the other end fixed to the base. One end of the duct is connected to the fan hood, and the other end is connected to a fan.

[0022] By adopting the above technical solution, a ventilation mechanism is set under the bracket, and a wind hood is set between the bracket and the base, so that the wind hood can cover the ventilation holes on the bracket. When the bracket is raised and lowered, the bellows tube can extend and retract with the bracket, thereby keeping the wind hood connected to the ventilation holes. By setting a duct on the wind hood, the fan can vent air into the wind hood through the duct, thereby allowing the airflow to flow through the ventilation holes and accelerating the efficiency of the spring heat treatment on the bracket.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting a bracket on the base and using a support column to support the bracket, a gap is formed between the base and the bracket. When a spring is placed on the bracket, the user can put the heat treatment rack into the heat treatment equipment, which allows the hot air to flow through the vent, so that the surface of the spring in contact with the bracket can exchange heat with the hot air, making the overall temperature of the spring uniform and achieving the effect of improving the uniformity of the heat treatment on the spring surface.

[0025] 2. By opening a placement slot on the bracket, the spring can be placed in the placement slot. By setting a locking pin on the inner wall of the placement slot, the spring can be sleeved on the locking pin, thereby keeping the spring in a stable position in the placement slot. When the heat treatment rack is placed in the heat treatment equipment, the probability of adjacent springs contacting each other can be reduced, resulting in higher heat treatment quality of the spring surface.

[0026] 3. By installing a ventilation mechanism under the bracket and a fan hood between the bracket and the base, the fan hood can cover the ventilation holes on the bracket. When the bracket is raised or lowered, the bellows tube can extend or retract with the bracket, thus keeping the fan hood connected to the ventilation holes. By installing a duct on the fan hood, the fan can ventilate into the fan hood through the duct, thus allowing the airflow to flow through the ventilation holes and accelerating the efficiency of the spring heat treatment on the bracket.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a spring heat treatment rack, as shown in the embodiments below. Figure 1 and Figure 2 The heat treatment rack includes a base 1, support columns 2, and a bracket 3. Multiple support columns 2 are vertically mounted on the base 1, perpendicular to it. The upper side of each support column 2 is detachably connected to the bracket 3. A gap exists between the base 1 and the bracket 3. The support columns 2 support the bracket 3. The bracket 3 holds springs and has multiple ventilation holes 311. When the user places the heat treatment rack in a high-temperature environment, high-temperature gas flows through the ventilation holes 311, ensuring even heating of the multiple springs on the bracket 3 and resulting in better heat treatment performance.

[0035] Reference Figure 3 and Figure 4 The upper end of the support column 2 is provided with a horizontal beam 21. Multiple horizontal beams 21 form a rectangular frame structure. The bracket 3 is inserted into the space between the horizontal beams 21, thus being detachably connected to the base 1. Multiple support rods 22 are provided on the horizontal beams 21. The support rods 22 are vertically arranged. The upper end of the support rod 22 is connected to the horizontal beam 21, and the lower end is fixed to the base 1. The support rods 22 are used to support the horizontal beams 21. When a heavy spring is placed on the bracket 3, the bracket 3 can be stably set on the support column 2.

[0036] Reference Figure 2 The bracket 3 has a placement groove 31 for placing springs. A vent 311 is provided at the bottom of the placement groove 31. Multiple locking pins 32 are provided in the placement groove 31, and the ends of the springs can be sleeved on the locking pins 32, so that the multiple springs in the placement groove 31 do not contact each other. When the heat treatment rack and the springs are heat treated, the surface of each spring is heated evenly.

[0037] Reference Figure 2Multiple locking pins 32 are disposed on the inner side wall of the placement groove 31. The length direction of the locking pins 32 is horizontal, and the multiple locking pins 32 are spaced apart along a straight line. The locking pins 32 are disposed on opposite side walls of the placement groove 31 and their positions correspond one-to-one. When the spring is placed in the placement groove 31, both ends of the spring can be respectively fitted onto a locking pin 32, thereby making the spring stably disposed in the placement groove 31. When the heat treatment rack is misaligned, it can reduce the probability of the spring rolling and abutting against each other in the placement groove 31.

[0038] Reference Figure 3 In other embodiments, the locking pin 32 is vertically disposed at the bottom of the placement groove 31, and the spring is vertically disposed in the bracket 3 with its lower end sleeved on the locking pin 32. Vent holes 311 are arranged at intervals around the circumference of the locking pin 32. When the spring is sleeved on the locking pin 32, hot air flows through the vent holes 311, thereby making the heat treatment of the spring more uniform.

[0039] Reference Figure 3 and Figure 4 The bracket 3 is equipped with an adjustment mechanism 4, which includes a screw 41, a handwheel 42, and guide rods 43. The screw 41 passes through the bracket 3 and is threadedly connected to it. The length direction of the screw 41 is parallel to the length direction of the support column 2. The lower end of the screw 41 is rotatably connected to the base 1, and the upper end is connected to the handwheel 42. Multiple guide rods 43 are provided and installed on the crossbeam 21. The length direction of the guide rods 43 is parallel to the length direction of the support column 2. The guide rods 43 pass through the edge of the bracket 3, allowing the bracket 3 to slide and connect with the guide rods 43. By turning the handwheel 42, the user can rotate the screw 41, thereby allowing the bracket 3 to move vertically back and forth relative to the screw 41. When the length of the spring placed on the bracket 3 is large, the user can adjust the position of the bracket 3 to change the overall height of the heat treatment rack, so that the heat treatment rack and spring can be placed into the heat treatment equipment.

[0040] In other embodiments, the screw 41 is movably connected to the base 1. By turning the screw 41, the user can make the screw 41 move vertically relative to the bracket 3, thereby causing the top of the screw 41 to abut against the base 1, thus achieving the effect of making the bracket 3 move vertically.

[0041] Reference Figure 5 A ventilation mechanism 5 is provided below the bracket 3. The ventilation mechanism 5 includes a fan hood 51 and a duct 52. The duct 52 can be a bellows pipe, with one end connected to the bottom of the bracket 3 and the other end connected to the base 1. The bellows pipe hood is located outside the vent hole 311 of the bracket 3. One end of the duct 52 is connected to the fan hood 51, and the other end is connected to a fan. The fan is used to ventilate the fan hood 51 through the duct 52, thereby allowing airflow to pass through the vent hole 311. By providing a ventilation mechanism 5 below the bracket 3, the airflow speed can be accelerated, thereby improving the heat treatment quality of the springs on the bracket 3.

[0042] The implementation principle of this application embodiment is as follows: By setting a support column 2 on the base 1, setting a bracket 3 above the support column 2, and opening multiple ventilation holes 311 at the bottom of the bracket 3, airflow can be allowed to pass through the ventilation holes 311, thereby improving the heat treatment quality of the spring on the bracket 3. By setting multiple locking pins 32 on the bracket 3, one end of the spring can be sleeved on the locking pins 32. When the heat treatment rack is placed in the heat treatment equipment, the probability of the springs hitting each other can be reduced, so that the surface of the spring can be in uniform contact with the hot air, and the heat treatment quality of the spring is better.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
