Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a cylinder head stamping machine for automobile engines. Background Technology

[0002] In the automotive manufacturing industry, the engine is the core component of a car, and its performance directly affects the vehicle's power output, fuel economy, and reliability. The cylinder head, as a key component of the engine, undertakes important functions such as sealing the cylinder and installing valves and spark plugs. Its manufacturing precision and quality play a decisive role in the overall performance of the engine. The stamping process, as an important step in the cylinder head production process, is mainly used for punching holes in the cylinder head. Through the cooperation of a stamping press and stamping dies, holes of various specifications are precisely machined on the cylinder head to meet the assembly requirements of the engine's internal structure.

[0003] Traditional automotive engine cylinder head stamping machines typically use dies with a fixed diameter design. Because different automotive engine cylinder head models have diverse punching specifications, operators must frequently change the matching fixed-diameter dies when producing cylinder heads with different hole diameter requirements. Frequent die changes not only increase equipment downtime and reduce production efficiency but also significantly increase the workload of equipment debugging during production. Furthermore, if any part of the fixed-diameter die is damaged, even a localized problem, the entire die often needs to be replaced. Therefore, developing an automotive engine cylinder head stamping machine that can flexibly adjust the punching size, facilitate disassembly and maintenance, and reduce production costs has become an urgent problem to be solved in the industry. Summary of the Invention

[0004] The purpose of this invention is to provide an automotive engine cylinder head stamping machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping machine for automobile engine cylinder heads, comprising a stamping worktable and a stamping machine for punching, wherein the stamping machine is disposed above the surface of the stamping worktable, and a stamping die is disposed on the surface of the stamping worktable, the stamping die comprising a fixed sleeve, a coarse-diameter die and a fine-diameter die, the fixed sleeve being fixed to the inner top wall of the stamping worktable, the coarse-diameter die being disposed inside the fixed sleeve, and the fine-diameter die being disposed inside the coarse-diameter die.

[0006] Preferably, the inner wall of the fixed sleeve is provided with a first slide rail, and the inner wall of the fixed sleeve above the first slide rail is provided with a first annular limiting groove, and the first slide rail is connected to the first annular limiting groove.

[0007] Preferably, a first knob is fixed on the outer surface of the coarse-diameter mold, and the first slide and the first annular limiting groove are both slidably adapted to the first knob.

[0008] Preferably, the inner wall of the coarse diameter mold is provided with a second slide, the inner wall of the coarse diameter mold above the second slide is provided with a second annular limiting groove, and the interior of the coarse diameter mold below the second slide is provided with a third annular limiting groove, and the second slide, the second annular limiting groove and the third annular limiting groove are connected to each other.

[0009] Preferably, a second knob is fixed on the outer surface of the fine-diameter mold, and the second slide, the second annular limiting groove and the third annular limiting groove are all slidably adapted to the second knob.

[0010] Preferably, the upper end of the coarse diameter die has a coarse die opening, the upper end of the fine diameter die has a fine die opening, the lower end of the fine diameter die is fixed with a hollow operating rod, and the front end of the stamping worktable is rotatably connected to an inspection door.

[0011] This utility model provides a cylinder head stamping machine for automobile engines, which has the following advantages compared with the prior art:

[0012] By designing a dual-diameter die structure, namely a combination of a coarse-diameter die and a fine-diameter die, users can flexibly adjust the punching pattern by whether the fine-diameter die occupies the coarse-diameter die according to the actual punching size requirements of the cylinder head. When a smaller hole diameter is required, the fine-diameter die's small opening is used; when a larger hole diameter is required, the fine-diameter die can be moved out of the coarse opening to fully utilize the function of the coarse-diameter die. Compared with traditional fixed-diameter dies, this design greatly improves the adaptability of the stamping machine to complex punching requirements, effectively avoids the trouble of changing equipment or dies due to mismatched hole diameters, and significantly improves production efficiency.

[0013] The combination of the coarse-diameter die, the fine-diameter die, the first knob, and the fixed sleeve allows for convenient assembly and disassembly of the coarse-diameter die and the fine-diameter die assembly within the fixed sleeve. The operation is simple and efficient, greatly saving installation and disassembly time, reducing the labor intensity of workers, and facilitating the daily maintenance and repair of the die. Since the combination of the coarse-diameter die and the fine-diameter die can be assembled and disassembled independently, when the die opening is damaged, users can selectively replace the specific coarse-diameter die or the fine-diameter die according to the actual damage, without having to replace the entire die, effectively reducing maintenance costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a cylinder head stamping machine for automobile engines, including a stamping worktable 1 and a stamping machine 3 for punching. The stamping worktable 1 serves as the basic support structure of the entire equipment, supporting the stamping die and the cylinder head workpiece to be processed. The stamping machine 3 is located above the table surface of the stamping worktable 1, and provides punching power. The stamping machine 3 applies pressure to the cylinder head workpiece through the punching head to complete the punching operation. A stamping die 4 is provided on the table surface of the stamping worktable 1. The stamping die 4 includes a fixed sleeve 5 and a roughing die. The coarse-diameter die 6 and the fine-diameter die 7 are used to adjust the punching die structure of the coarse-diameter die 6. The fine-diameter die 7 has a fine die opening 17 at the upper end for processing holes with smaller diameters. The fixed sleeve 5 is fixed on the inner top wall of the stamping worktable 1. The coarse-diameter die 6 is set inside the fixed sleeve 5, and the fine-diameter die 7 is set inside the coarse-diameter die 6. By combining the coarse-diameter die 6 and the fine-diameter die 7 and adjusting their positions, the punching modes of "large diameter" and "small diameter" can be switched to adapt to the processing requirements of different hole diameters in the cylinder head.

[0021] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the inner wall of the fixed sleeve 5 is provided with a first slide rail 9, and the inner wall of the fixed sleeve 5 above the first slide rail 9 is provided with a first annular limiting groove 10. The first slide rail 9 and the first annular limiting groove 10 are connected. The outer surface of the coarse diameter mold 6 is fixed with a first knob 8. The first slide rail 9 and the first annular limiting groove 10 are both slidably adapted to the first knob 8. The inner wall of the coarse diameter mold 6 is provided with a second slide rail 13, and the inner wall of the coarse diameter mold 6 above the second slide rail 13 is provided with a second annular limiting groove 14. The interior of the coarse diameter mold 6 below the second slide rail 13 is provided with a third annular limiting groove 15. The second slide rail 13, the second annular limiting groove 14 and the third annular limiting groove 15 are connected.

[0022] Further as Figure 4 As shown, it is worth noting that a second knob 12 is fixed on the outer surface of the fine-diameter mold 7, and the second slide rail 13, the second annular limiting groove 14 and the third annular limiting groove 15 are all slidably adapted to the second knob 12. The upper end of the coarse-diameter mold 6 is provided with a coarse mold opening 16, the upper end of the fine-diameter mold 7 is provided with a fine mold opening 17, the lower end of the fine-diameter mold 7 is fixed with a hollow operating rod 11, and the front end of the stamping worktable 1 is rotatably connected to an inspection door 2.

[0023] This solution has the following working process: Before use, the fine-diameter die 7 slides into the second annular limiting groove 14 or the third annular limiting groove 15 along the second slide 13 of the coarse-diameter die 6 via the second knob 12. When the height is adjusted, the second knob 12 is turned to the second annular limiting groove 14 or the third annular limiting groove 15. This allows the fine-diameter die 7 and the coarse-diameter die 6 to be used in combination. When the cylinder head needs to be punched with a small hole, the fine-diameter die 7 replaces the coarse die opening 16 of the coarse-diameter die 6 with a smaller fine die opening 17. When the cylinder head needs to be punched with a larger hole, the fine-diameter die 7 is adjusted to the height of the third annular limiting groove 15 of the coarse-diameter die 6. The fine-diameter die 7 can be removed from the coarse die opening 16 of the coarse-diameter die 6 so that the coarse die opening 16 can cooperate with the corresponding punching head to perform punching operation. The combination formed by the coarse-diameter die 6 and the fine-diameter die 7 can replace the traditional fixed-diameter punching die opening and adapt to complex punching application requirements.

[0024] During use, the combination of the fine-diameter die 7 and the coarse-diameter die 6 is lifted to the height of the first annular limiting groove 10 along the first slide 9 of the fixed sleeve 5 by the first knob 8. Finally, the first knob 8 is screwed into the first annular limiting groove 10 of the fixed sleeve 5. In this way, the combination of the coarse-diameter die 6 and the fine-diameter die 7 is assembled and disassembled in the fixed sleeve 5. The availability of a replacement combination of the coarse-diameter die 6 and the fine-diameter die 7 makes it convenient to replace them independently as needed after the die opening is damaged.
