[0043] The tempering furnace unit 1 includes a frame 11 and a conveying assembly 12. The frame 11 forms a tempering chamber inside. The conveying assembly 12 is connected to the frame 11 and passes through the tempering chamber. The conveying assembly 12 has a feeding end and a discharging end. The conveying assembly 12 can convey the spring workpiece from its feeding end into the tempering chamber, and then convey it from the tempering chamber to its discharging end.

During the operation process, it can reduce unnecessary transportation during traditional strong pressing and cooling operations, reduce the investment of manpower and material resources, not only increase work efficiency, but also save costs, and achieve the purpose of reducing costs and increasing efficiency.

[0046] The conveying assembly 12 includes a fixing plate 121 , an inverted V-shaped conveying plate 122 , a sprocket chain conveying mechanism 123 , a pushing plate 124 and a pushing rod 125 .

[0049] After the spring workpiece has completed the preceding process, it can be placed on the feed end of the inverted V-shaped conveying plate 122 , and then the spring workpiece can be transported and moved in each gap, and finally leave from the feed end of the inverted V-shaped conveying plate 122 .

[0050] The sprocket chain transmission mechanism 123 is connected to the frame 11. The sprocket chain transmission mechanism 123 is preferably a combination structure of a driving sprocket, a driven sprocket, a chain and a driving motor.

One side of the push plate 124 is connected to a plurality of push rods 125 in its length direction. The plurality of push plates 124 are connected to the chain transmission of the sprocket chain transmission mechanism 123. After the sprocket chain transmission mechanism 123 is started, the chain can drive all the push plates 124 and the push rods 125 to rotate in a circle. When the corresponding push plate 124 is located below the inverted V-shaped transmission plate 122, each push rod 125 on the push plate 124 can pass upward from a corresponding gap. At this time, each push rod 125 can contact the tail end of the corresponding spring workpiece. Under the push of the push rod 125, the spring workpiece can be pushed in the corresponding gap, thereby forming movement.

[0052] The tempering furnace unit 1 further includes a cooling assembly 13 and a heating assembly. The cooling assembly 13 is connected to the frame 11. The bottom of the cooling assembly 13 is located inside the tempering chamber and above the conveying assembly 12 and the spring workpiece.

[0053] The heating component is connected to the frame 11 and is located inside the tempering chamber. In this embodiment, the heating component is preferably a heating tube. The number of heating tubes can be hundreds, evenly distributed above and below the conveying component 12 and the spring workpiece. Since the heating tube is a relatively conventional prior art, it is not shown in the accompanying drawings.

[0054] The cooling assembly 13 includes a fixing frame 131, a cooling motor 132 and a cooling fan 133. The fixing frame 131 is connected to the frame body 11, the cooling motor 132 is connected to the top of the fixing frame 131, the output shaft of the cooling motor 132 extends into the tempering chamber and is in transmission connection with the cooling fan 133, and the cooling fan 133 is located above the conveying assembly 12 and the spring workpiece;

[0058] After the blocking cylinder 141 is started, it can drive the blocking plate 142 to move vertically. The blocking plate 142 can move by sliding between the first slider 143 and the first slide rail 144. When the blocking plate 142 moves downward to the extreme position, it can contact the upper surface of the inverted V-shaped transfer plate 122. At this time, the inside of the tempering chamber can be isolated and the temperature in the tempering chamber can be controlled.

[0059] The application principle of the tempering furnace unit 1 is as follows: the spring workpieces are placed in order in the gap between two adjacent inverted V-shaped conveying plates 122, the heating rod is started to heat, so that the inside of the tempering chamber reaches the specified temperature, the sprocket chain conveying mechanism 123 is started, and the chain transmission drives the push plate 124 and the push rod 125 to move from the feeding end of the conveying assembly 12 to the discharging end, and the push rod 125 can push the corresponding spring workpiece to move in the gap. When the temperature is too high, the cooling motor 132 is started to drive the cooling fan 133 to rotate, thereby dissipating the heat of the tempering chamber. When the spring workpiece at the front is When the spring workpiece needs to be discharged, the blocking cylinder 141 contracts, driving the blocking plate 142 to move upward. After the discharge is completed, the blocking cylinder 141 extends, driving the blocking plate 142 to move downward, and contacts the inverted V-shaped conveying plate 122, thereby temporarily closing the tempering chamber. Through the coordinated application of the above components, the tempering furnace unit 1 can accurately control the temperature inside the tempering chamber. At the same time, with this structure, multiple spring workpieces can be fed at the same time to ensure the tempering efficiency. At the same time, since the spring workpieces in the same row move together, the orderly discharge of the spring workpieces can be guaranteed.

[0060] As an optional embodiment, the strong pressing unit 2 includes a bracket 21, a vertical moving component 22, a strong pressing rod 23, a guide component 24, a lateral moving component 25, a sliding plate 26, a strong pressing tooling 27, a cooling block 28 and a flip feeding component 29.

The bracket 21 is preferably in the form of a gantry, so as to effectively improve the structural strength. When necessary, the bracket 21 can be connected to the frame 11 to form an integral structure.

[0062] The vertical moving assembly 22 includes a high-pressure electric cylinder 221 and a lifting block 222.

In this embodiment, the guide assembly 24 preferably includes a guide shaft, and the two guide shafts are fixedly connected to the bracket 21 and are movably connected to the lifting block 222, thereby forming a guiding effect on the moving lifting block 222.

After the sliding cylinder is started, it can drive the sliding plate 26 and all the strong pressure fixtures 27 to move synchronously horizontally. There is a strong pressure fixture 27 corresponding to each strong pressure rod 23 below it. In this embodiment, the number of strong pressure fixtures 27 and strong pressure rods 23 corresponds to the number of inverted V-shaped transmission plates 122. The attached drawings preferably show a structural form with a number of twelve;

[0066] The sliding plate 26 preferably includes a main board located on a horizontal plane and a guide plate connected to the main board, each guide plate corresponds to a group of strong pressing tooling 27 and a strong pressing rod 23, and the guide plates are preferably located on both sides of the path where the spring tooling slides and falls into the strong pressing tooling 27, one side of which can be a vertical plate and the other side is an inclined plate, one side of the inclined plate is close to the flip feed plate 292 described below, so that it can form a docking with the flip feed plate 292 in the flipped state, so that the spring workpiece can slide into the strong pressing tooling 27 more accurately.

[0067] The cooling block 28 is connected to the bracket 21 and is connected to the water-cooling circulation unit 3.

The cooling block 28 is located below the spring workpiece, so that it can play a temporary supporting role for the spring workpiece. The front end of the cooling block 28 is preferably provided with an inclined surface, which can facilitate the free fall of the spring workpiece.

[0068] The flip feed assembly 29 includes a flip feed shaft 291, a flip feed plate 292 and a flip feed cylinder 293.

[0069] The application principle of the strong pressure unit 2 is as follows: when not in use, the flip feed cylinder 293 does not work, and the flip feed plate 292 is in a horizontal state. When the spring workpiece moves to the corresponding position of the flip feed plate 292, the flip feed cylinder 293 starts to extend, driving the flip feed plate 292 to flip and form an inclined state. The spring workpiece can slide to the inside of the strong pressure fixture 27 through the sliding plate 26, and then the strong pressure electric cylinder 221 starts to drive the lifting block 222 and all the strong pressure rods 23 to move downward with the assistance of the guide shaft, so that the bottom of the strong pressure rod 23 extends into the inside of the strong pressure fixture 27, and the spring workpiece located inside the strong pressure fixture 27 is strongly pressed. At the same time, the liquid spraying port of the cooling block 28 sprays coolant to cool the spring workpiece while it is being strongly pressed.

[0070] After complete forced cooling, the flip feed cylinder 293 is retracted, the flip feed plate 292 is reset, and the forced electric cylinder 221 is started, driving the lifting block 222 and all the forced rods 23 to move upward with the assistance of the guide shaft, and then the sliding cylinder is started, driving the sliding plate 26 to move in the direction away from the tempering furnace unit 1. During this process, all the forced pressing fixtures 27 move synchronously and separate from the cooling block 28 supporting the spring workpiece. The spring workpiece inside the forced pressing fixture 27 falls freely due to gravity and slides from the inclined surface of the front end of the cooling block 28 to the external collection unit. Then the sliding cylinder is started, driving the sliding plate 26 to move in the direction of the tempering furnace unit 1, forming a reset for the next use;

[0071] The above-mentioned components can simultaneously complete the strong pressing process and the cooling process for the spring workpiece, and reduce the transportation steps, shorten the transportation time, and better save costs.

The water storage tank 31 is connected to each high-pressure fixture 27 through a circulation pipeline 32. The water outlet of the circulation pipeline 32 at each high-pressure fixture 27 actually corresponds to the liquid spraying port on the cooling block 28. The coolant stored in the water storage tank 31 can be transported to the water outlet through the circulation pipeline 32, and then sprayed from the corresponding liquid spraying port to cool the spring workpiece inside each high-pressure fixture 27. The sprayed coolant can drip freely by gravity.

[0074] The water tank 34 is located below the above structure and is used to receive and collect dripping coolant. The water pump 33 is connected to the water tank 31 and the water tank 34 respectively through the circulation pipeline 32. The number of water pumps 33 is preferably two, which are located on both sides respectively, so as to effectively improve the efficiency. After the water pump 33 is started, it can drive the coolant to self-circulate in the water cooling circulation unit 3. When the coolant needs to be sprayed, the water pump 33 is started to drive the coolant inside the water tank 34 to enter the water tank 31. At the same time, the coolant inside the water tank 31 is transported to the high-pressure tooling 27 through the circulation pipeline 32. The sprayed coolant can drip downward back into the water tank 34, thereby completing the self-circulation of the coolant, effectively reducing the consumption of the coolant, and further reducing the cost.
