Description

Technical Field

[0001] The utility model relates to the field of metal sheet forming, in particular to a metal sheet hot stamping heating pretreatment bin. Background Art

[0002] The metal sheet hot stamping heating pretreatment chamber is a special equipment for heat treatment of metal sheets. It is used to improve the forming performance of metal sheets in the subsequent stamping process and the quality of the final product. It is mainly used in the field of automobile manufacturing. It heats the metal sheets to a certain temperature, then performs stamping, and then quickly cools them to obtain high-strength, precisely formed parts.

[0003] After searching the Chinese patent document announcement number CN215686650U, a heating chamber is disclosed, including: a shell assembly, a heating chamber body and a rotation drive assembly; the shell assembly has a first cavity, and the heating chamber body is rotatably arranged in the first cavity; the heating chamber body has a second cavity for accommodating a container pot, and the heating chamber body also has at least one group of heating components; the rotation drive assembly is connected to the heating chamber body to drive the heating chamber body to flip. The heating chamber provided by the utility model has the characteristics of simple structure, easy operation and high efficiency.

[0004] The beneficial effects in the above patent specification mention that "the heating chamber provided by the utility model has the characteristics of simple structure, easy operation and high efficiency. The guide roller is in rolling contact with the shell assembly, especially with the front panel, to guide and support the rotation of the heating chamber. In the case where both the upper fixed plate and the lower fixed plate are provided with heating components, single-sided heating or double-sided heating can be selected during the cooking process, and the provision of a heat preservation component can improve the energy utilization rate. The provision of a heat insulation component can, on the one hand, avoid heat overflow and scalding the operator, and on the other hand, ensure the temperature of other devices to avoid safety hazards such as spontaneous combustion due to excessive temperature. Problem. The rotary drive assembly is used to rotate the heating chamber during the cooking process so that the food is heated and mixed evenly. The structure and position design of the front panel of the chamber door and the inner frame of the chamber door make the chamber door of the heating chamber hollow, which can prevent the door panel from overheating. The electromagnetic lock is provided to provide reliable locking for the chamber door, which improves the safety of the equipment when in use. "Although the above patent can solve the safety problems caused by heat overflow and the problem of low energy utilization, in the existing structure, it is easy to heat the metal sheet unevenly when heating it, which may affect the material properties: uneven heating will cause inconsistent internal organizational structure of the material, thereby affecting the mechanical properties of the material, such as strength, hardness and toughness. This inconsistency in performance will cause unpredictable risks and deformation defects in subsequent processing and use. Uneven heating will cause uneven shrinkage of metal materials during cooling, causing deformation and internal stress. These deformations and stress concentration areas may become the starting point of cracks, reducing the reliability and durability of parts. In addition, if the waste after stamping is not recovered in time, the next stamping movement may be affected and the utilization rate of raw materials is low, resulting in increased costs.

[0035] Reference Figure 1 , Figure 4 , Figure 5The middle part of the inner wall of the warehouse body 1 is fixedly connected with a heat insulation plate 26, which is used to separate the heating area and the stamping area to protect the stamping structure. The top of the bevel gear 1 9 is meshed with the top of the bevel gear 2 10. Through the meshing connection between the bevel gear 1 9 and the bevel gear 2 10, the power of the motor 4 is transmitted to the clamp structure to make it telescopic and rotatable. The bottom of the bevel gear 2 10 is rotatably connected to the inner wall of the heat insulation box 19, and the inner wall of the lifting column 20 is slidably connected to the outer wall of the support column 25, which plays a role in fixing the lifting structure so that it can be horizontally moved. The direction is stable, the rotating column 44 is rotatably connected to the bottom of the warehouse body 1, the top of the threaded rod 14 is in contact with the adjacent side of the two cylindrical blocks 16, and the two cylindrical blocks 16 are opened and closed by the movement of the threaded rod 14, driving the clamp structure to open and close, the top of the spring 30 is fixedly connected to the top inner wall of the installation box 29, the top of the cleaner 41 is in contact with the outer wall of the lower mold 34, the top of the hydraulic cylinder 27 is fixedly connected to the top inner wall of the warehouse body 1, and the bottom of the collection box 36 is fixedly connected to the bottom inner wall of the warehouse body 1.

[0036] Working principle: First, the operator opens the warehouse door 2, puts the metal sheet at the bottom of the warehouse body 1, turns on the motor 4 to make it work, and drives the rotating column 5 to rotate. When the internal protrusion 6 of the rotating column 5 contacts the protrusion 2 8 fixedly connected to the top of the telescopic column 7, the telescopic column 7 starts to rotate, thereby driving the bevel gear 19 to rotate, driving the bevel gear 2 10 meshing with it to rotate, driving the sleeve 11 to rotate, and making the threaded rod 14 move forward. The forward movement of the threaded rod 14 causes the two cylindrical blocks 16 to move to the far side, driving the clamp tail 15 to move to the far side, and driving the clamp head 18 to open through the connecting shaft 17. At the same time, due to the forward movement of the threaded rod 14, the entire clamp structure moves forward. When it moves to contact with the metal sheet, the motor 4 operates in the reverse direction, and the entire rotating structure rotates in the reverse direction. The threaded rod 14 moves backward, and when it moves out of between the two cylindrical blocks 16, the two cylindrical blocks 16 close, driving the chuck 18 to move to the adjacent side to clamp the metal sheet, turning the handle 2 43, driving the rotating disk 2 42 to rotate, driving the rotating column 2 44 to rotate, thereby driving the pulley 24 to rotate, causing the steel rope 23 to move, driving the lifting block 22 to move vertically, and through the fixing effect of the connecting block 21, driving the lifting column 20 to move vertically on the outer wall of the support column 25, adjusting the lifting mechanism to reach the corresponding height, due to the reverse operation of the motor 4, when the threaded rod 14 moves backward to the inner bottom end of the sleeve 11, the threaded rod 14 and the sleeve 11 perform the same rotational motion, driving the slider 12 to rotate, and transmitting to the clamp structure through the connecting column 13, driving the entire clamp structure to rotate, and at the same time turning on the heating plate 3 for heating operation.

[0037] The operator turns on the hydraulic cylinder 27 to make it operate, and transmits the power to the mounting box 29 through the hydraulic column 28, so that the upper mold 33 at the bottom of the mounting box 29 moves downward. After being squeezed in contact with the lower mold 34, the spring 30 inside the mounting box 29 is compressed due to the reaction force, reducing the reverse pressure on the hydraulic column 28 and the hydraulic cylinder 27, thus completing one stamping. Subsequently, by turning the handle 1 37, the rotating disk 1 38 is driven to rotate, thereby driving the sleeve 2 39 and the threaded rod 2 40 to rotate. Since the cleaner 41 is in contact with the lower mold 34 and will not rotate, the threaded rod 2 40 moves forward, driving the cleaner 41 to move forward, pushing the waste generated by the stamping onto the U-shaped track 35. Due to the action of gravity, the waste moves into the collection box 36.
