Description

Technical Field

[0001] This utility model relates to a heat cutting device, specifically a heat cutting device for ultra-thick steel leaf spring materials. Background Technology

[0002] Leaf springs are the most widely used elastic element in automotive suspensions. They are composed of several alloy spring leaves of equal width but unequal length, forming an elastic beam of approximately equal strength. Due to their excellent load-bearing and shock absorption capabilities, leaf springs are widely used in automobile manufacturing. In the manufacturing process of leaf springs, multiple steel plates need to be cut to obtain steel plates of specific lengths for assembly into leaf springs.

[0003] Some leaf springs are assembled from ultra-thick steel plates. Due to their large thickness, ultra-thick steel plates are difficult to cut using ordinary methods, which is time-consuming and labor-intensive. In the prior art, flame cutting is usually used to cut ultra-thick steel plates. Chinese patent application CN108480818A discloses a flame cutting method for ultra-thick steel plates, which includes the following steps: evacuating a container sealed on the lower surface of the steel plate to a vacuum of 85-95 kPa; preheating the steel plate to 90-110°C; positioning the flame gun head 13-17 mm above the steel plate, tilting the gun head 10°-15° relative to the vertical direction to perform uniform pre-cutting of the steel plate; when the pre-cutting reaches 1 / 4 to 1 / 2 of the steel plate thickness, positioning the flame gun head vertically above the steel plate to perform uniform final cutting.

[0004] Before flame cutting ultra-thick steel plate springs, the ultra-thick steel plate needs to be preheated. The ultra-thick steel plate is heated, and it is not possible for a person to directly contact and move it, which is dangerous. In addition, the ultra-thick steel plate is thicker, which increases its weight and makes manual handling more difficult, which greatly affects the cutting efficiency. Utility Model Content

[0018] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1-3 As shown, a hot-cutting device for ultra-thick steel plate spring material includes a base 1. A long, narrow conveying trough 11 is provided in the center of the top surface of the base 1. Several conveying rollers 12 are arranged along the length of the conveying trough 11 within the conveying trough 11. A flame-cutting position 13 is provided in the center of the conveying trough 11. A first clamping assembly a and a second clamping assembly b, with identical structures, are respectively provided on both sides of the flame-cutting position 13, corresponding to the front and rear sides of the conveying trough 11, for clamping ultra-thick steel plates. The first clamping assembly a includes a first clamping block 21 and a second clamping block 22 symmetrically arranged to clamp both sides of the ultra-thick steel plate. The first clamping assembly a and the second clamping assembly b can simultaneously clamp and release the ultra-thick steel plate. The conveying trough fixes several conveying rollers to form a conveying line, and a flame-cutting position is formed between two widely spaced conveying rollers in the center of the conveying trough. This design ensures that the conveyor rollers avoid the flame, preventing damage to them. Flame cutting is an existing technology and will not be elaborated here. Before flame cutting, ultra-thick steel plates require preheating to prevent excessive deformation that could prevent them from being assembled into leaf springs. The first and second clamping components are located at the front and rear of the flame cutting position, respectively, and clamp the two sections of ultra-thick steel plate formed after cutting using the first and second clamping blocks for easy transfer and fixation. This eliminates the need for manual handling of the preheated ultra-thick steel plate, improving safety and reducing labor. Simultaneously, clamping and fixing the ultra-thick steel plate during cutting prevents it from shifting or loosening, ensuring accurate cutting position and quality. Furthermore, the cut plate can be directly transferred via the conveyor rollers, effectively improving the cutting and transfer efficiency of ultra-thick steel plates.

[0020] like Figure 2-3As shown, the first clamping block 21 includes a first horizontal portion 211 that abuts against one side of the top surface of the ultra-thick steel plate, and a first vertical portion 212 that abuts against the side wall of one side of the ultra-thick steel plate and is perpendicularly connected to the first horizontal portion 211. The second clamping block 22 includes a second horizontal portion 221 that abuts against the other side of the top surface of the ultra-thick steel plate, and a second vertical portion 222 that abuts against the side wall of the other side of the ultra-thick steel plate and is perpendicularly connected to the second horizontal portion 221. The bottom of the first vertical portion 212 is provided with a plurality of first support rods 213 extending toward the bottom of the ultra-thick steel plate and abutting against the bottom surface of the ultra-thick steel plate. The bottom of the second vertical portion 222 is provided with a plurality of second support rods 223 extending toward the bottom of the ultra-thick steel plate and abutting against the bottom surface of the ultra-thick steel plate. Both the first support rods 213 and the second support rods 223 can extend into the gap between two adjacent conveying rollers 12. The top surface of the first horizontal portion 211 is provided with... A first drive arm 23 extends laterally toward the second horizontal portion 221, and a second drive arm 24 extends laterally toward the first horizontal portion 211 on the top surface of the second horizontal portion 221. The first drive arm 23 and the second drive arm 24 are arranged in parallel. The first horizontal portion, the first vertical portion, the second horizontal portion, and the second vertical portion abut against the top and side surfaces of the ultra-thick steel plate, forming a top limit and a lateral limit on the ultra-thick steel plate. Together with the first support rod and the second support rod, they support the bottom of the ultra-thick steel plate, forming a limit and fixation of the ultra-thick steel plate, preventing the ultra-thick steel plate from shifting laterally or longitudinally, and ensuring the stability of the ultra-thick steel plate during cutting. The first drive arm and the second drive arm can be connected to the first clamping block and the second clamping block to maintain the clamping action of the first clamping block and the second clamping block, and ensure the stability of the first clamping block and the second clamping block when they move relative to each other.

[0021] like Figure 1-3As shown, a transmission gear 25 is provided between the first drive arm 23 and the second drive arm 24. The side walls of the first drive arm 23 and the second drive arm 24 are respectively provided with a first gear set 231 and a second gear set 241 that mesh with the transmission gear 25. A drive motor 251 is provided above the transmission gear 25. A top plate 26 is fixed to the top of the drive motor 251. The drive motor 251 is fixed to a fixing bracket 261 connected to the bottom of the top plate 26. The output shaft of the drive motor 251 passes through the fixing bracket 261 and connects to the shaft of the transmission gear 25. The bottom sides of the top plate 26 are respectively provided with gears that mesh with the first drive gear 25. The first fixed block 27 and the second fixed block 28 connect the drive arm 23 and the second drive arm 24. The top surfaces of the first drive arm 23 and the second drive arm 24 are respectively provided with a first T-shaped groove 232 and a second T-shaped groove 242 arranged along the moving direction. The bottoms of the first fixed block 27 and the second fixed block 28 are respectively provided with a first T-shaped block 271 and a second T-shaped block 281 that mate with the first T-shaped groove 232 and the second T-shaped groove 242. Two U-shaped brackets 14 are provided above the base 1, spanning both sides of the base 1 and located above the first clamping assembly a and the second clamping assembly b. A drive cylinder 141 is provided on the top of the U-shaped bracket 14. The cylinder rod of the drive cylinder 141 passes downward through the U-shaped bracket and connects to the top surface of the top plate 26. The first drive arm and the second drive arm are respectively provided on opposite sides. The first and second gear sets are meshed with the two sides of the transmission gear, so that the rotation of the transmission gear can drive the first drive arm and the second drive arm synchronously through the first and second gear sets. This allows the first drive arm and the second drive arm to drive the first clamping block and the second clamping block to move relative to each other, thereby realizing the clamping action of the first clamping block and the second clamping block, ensuring the stability and reliability of the clamping. The drive motor can drive the transmission gear, so that the transmission gear rotates to drive the first drive arm and the second drive arm to move relative to each other. At the same time, when the first drive arm and the second drive arm move, the first drive arm and the second drive arm are slidably connected to the first T-shaped block and the second T-shaped block at the bottom of the first fixed block and the second fixed block through the first T-shaped groove and the second T-shaped groove at the top. This allows the first drive arm and the second drive arm to slide relative to each other under the support of the top plate and the drive of the transmission gear, thereby realizing the action of the first clamping block and the second clamping block.

[0022] Before flame cutting the ultra-thick steel plate, the ultra-thick steel plate is clamped and fixed on the front and rear sides of the flame cutting position by the first clamping assembly and the second clamping assembly. Then, the ultra-thick steel plate is lifted by the drive cylinder through the upward control of the top plate, so that the ultra-thick steel plate is separated from the conveying roller. This avoids the wear on the bottom surface of the ultra-thick steel plate caused by the continuous rotation of the conveying roller during cutting, and avoids the need to stop the conveying roller during cutting, which would increase the energy consumption and equipment wear due to frequent shutdowns. After the ultra-thick steel plate is lifted, it can be flame cut. After the cutting is completed, the ultra-thick steel plate cut to the specified length is moved down and placed on the conveying roller for transfer. The remaining ultra-thick steel plate can be moved down and placed on the conveying roller at the same time, and directly transported through the flame cutting position for continuous cutting. This realizes the mechanized continuous cutting of ultra-thick steel plates and effectively improves the cutting efficiency and cutting safety.

[0023] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
