Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a double-door through trolley type heat treatment furnace. Background Art

[0002] In production scenarios that require large-scale implementation of the same or similar heat treatment processes, such as automotive parts manufacturing, aerospace parts manufacturing, etc., the double-door trolley type heat treatment furnace can effectively improve production efficiency and product quality through rapid workpiece loading and unloading operations and the front-to-back through of the trolley. For cases where multiple heat treatment processes need to be performed on the same workpiece, such as quenching followed by tempering, or multiple quenching treatments, etc., the double-door through design allows the workpiece to move back and forth inside the furnace chamber, facilitating the sequential combination of different processes and ensuring the performance requirements of the final workpiece.

[0003] Chinese Patent CN218811881U discloses a trolley type heat treatment furnace, including: a furnace body, a heat treatment chamber arranged inside the furnace body, and a traction trolley outside. A connecting rail penetrates forward inside the lower end of the heat treatment chamber, and the lower end of the connecting rail is flush with the lower end of the furnace body and is fixed on the ground. By arranging a support slider and a telescopic spring on the upper end of the support plate, the support slider at the lower end of the heat treatment part is pressed down to form a concave surface, and the support slider that is not pressed down forms a convex surface, so that the concave and convex surfaces limit the position of the heat treatment part. At the same time, the heat treatment part can slide on the upper end of the support plate through the rolling of the balls, making it easier to adjust the position of the heat treatment part on the upper end of the support plate. The traction trolley and the support plate are connected through a buffer cross column and a buffer spring, so that the support plate can slide up and down inside the buffer chute through the buffer cross column and the buffering of the buffer spring, reducing the impact of the gravity of the heat treatment part on the support plate and preventing the support plate from deforming under the impact of the heat treatment part, thereby improving the service life.

[0004] The above patent is based on the connection between the traction trolley and the support plate through a buffer spring and a buffer cross column, so as to reduce the impact of the gravity of the heat treatment part on the support plate, and thus improve the service life of the device. However, it does not consider that after the device finishes heating the workpiece, it is necessary for the staff to manually remove the heated workpiece, which will increase the workload of the staff.

[0042] Working steps

[0043] First, the operator places the workpiece to be heated on the top of the mobile cart 19. After starting the equipment, the electric guide rail 18 drives the mobile cart 19 to move smoothly along the set path and sends the workpiece into the heating furnace 20. At this time, the second hydraulic rod 25 is activated, causing the second hydraulic rod 25 to drive the connecting plate 26 to move. Furthermore, through the cooperation of the connecting plate 26 and the tension rope 27, the tension rope 27 drives the second fixing plate 23 to move. When the second fixing plate 23 moves, it will drive the heat preservation cover 21 to rise stably along the guiding rod 22, so that the workpiece is safely enclosed inside the heating furnace 20 for heating.

[0044] After heating is completed, the mobile cart 19 moves the heated workpiece out of the heating furnace 20 and sends it to the other side of the equipment. At this time, the push rod 3 in the driving assembly starts, pushing the moving plate 4 to move along the support frame 2 to an appropriate position. At the same time, the lifting assembly on the moving plate 4 is activated, and the clamping plate 13 is adjusted to an appropriate height through the first hydraulic rod 5, so that the clamping plate 13 automatically opens under the drive of the motor 8 and the semi-gear system, clamps the workpiece. Subsequently, the push rod 3 is started again, and the push rod 3 drives the clamping plate 13 to drive the clamped workpiece to move through the push plate 4. Thus, the clamping plate 13 safely moves the workpiece into the cooling box 17 for rapid cooling treatment.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
