Description

Technical Field

[0001] The utility model relates to the technical field of annealing equipment, in particular to a stress relief annealing device for die steel. Background Art

[0002] Annealing treatment is required in the processing and production of mold steel. The metal or alloy is heated to an appropriate temperature, kept warm for a certain period of time, and then slowly cooled. This heat treatment process is called annealing, which is generally carried out in a trolley-type annealing furnace.

[0003] Chinese utility model patent: Publication number CN218561510U, discloses a furnace body including a support platform and a support plate and a slide plate are slidably provided at the top of the support platform, a side plate is provided on the outside of the support platform, a rotating shaft 1 is rotatably provided on the outer wall of the side plate, a rotating shaft 2 is provided on the top of the support platform near one end of the rotating shaft, a rope is provided on one side of the outer wall of the slide plate, a steel chain is provided on the other side of the outer wall of the slide plate, a hook is provided on the outer wall of the steel chain, a hanging hole matching the hook is provided on the side wall of the support plate, a multi-section cylinder is provided on the side wall of the furnace body, through holes are symmetrically provided on the side wall of the support plate, and cooling components are symmetrically provided on the outer wall of the side plate.

[0004] In the existing technology, when CN218561510U is in use, by setting the furnace body, rope, support plate, nozzle and support plate, the slide plate can pull the steel chain, so that the equipment can carry out continuous production and occupy a more concentrated space. During annealing processing, there is no need to carry it back and forth to multiple places in the factory, and the mold steel can be continuously heated and cooled, thereby improving production efficiency.

[0005] However, the inlet and outlet design of the currently used mold steel stress relief annealing device is only set on one side. This design requires the annealing process to remove the annealed mold steel before putting in the new mold steel. This single inlet and outlet design limits the work efficiency, so a mold steel stress relief annealing device is needed to solve the above problem. Utility Model Content

[0006] The utility model aims to provide a stress relief annealing device for mold steel, which has the advantages of simultaneously loading new mold steel and unloading annealed mold steel, thereby improving work efficiency and solving the problem that the annealing device design with a single inlet and outlet limits work efficiency.

[0007] To achieve the above object, the utility model provides the following technical solutions: a mold steel stress relief annealing device, comprising a support frame, a base is fixedly installed in the middle of the inner side of the support frame, a protective frame is fixedly installed on the upper surface of the support frame outside the base, and also includes a landing gear and a transmission roller;

[0008] The transmission rollers are rotatably mounted on both ends of the inner side of the support frame;

[0009] Among them, the two transmission rollers are connected by steel wire rope transmission;

[0010] The landing gear is movably mounted on the outside of the protective frame.

[0011] When using a mold steel stress relief annealing device in the technical solution, the landing gear is raised by starting the electric telescopic rod. At this time, the mold steel to be annealed can be placed on the steel wire rope on one side of the protective frame. By starting the driving mechanism body, the mold steel to be annealed can be moved to the upper surface of the base through the steel wire rope. At this time, the electric telescopic rod can be started again to make the landing gear fall down and the inner space of the protective frame relatively sealed, and then the starter body is started to heat and keep the inner side of the protective frame through the resistance heater. After that, the mold steel is annealed by slow cooling. When it is necessary to take out the current annealed mold steel, the subsequent mold steel to be annealed is placed on the steel wire rope on one side of the protective frame, and the landing gear is raised. The subsequent mold steel to be annealed is moved to the upper surface of the base through the steel wire rope. At the same time, the mold steel that has been annealed is moved out from the other side above the base, thereby realizing the operation of loading new mold steel and unloading annealed mold steel at the same time.

[0012] Preferably, second limiting grooves are provided at both upper and lower ends of the base, and the steel wire rope passes through the second limiting grooves.

[0013] By opening second limiting grooves at both ends of the base and passing the steel wire rope through the second limiting grooves, the base can prevent the steel wire rope from getting stuck after carrying heavy objects. In addition, the second limiting grooves can also limit the movement of the steel wire rope.

[0014] Preferably, a mounting groove is provided on the top of the protection frame, a controller body is fixedly mounted on the top of the protection frame outside the mounting groove, a resistance heater is fixedly mounted on the bottom of the controller body, and the resistance heater is located inside the mounting groove.

[0015] By fixing a resistance heater at the bottom end of the controller body and installing the resistance heater inside the installation groove, the mold steel inside the protective frame can be heated and kept warm by the resistance heater.

[0016] Preferably, the outer walls of the two transmission rollers are each provided with a first limiting groove, the first limiting groove is provided with a convex pattern perpendicular to the wire rope, the wire rope passes through the first limiting groove, and the front ends of the two transmission rollers pass through the support frame and are fixedly mounted with a driven sprocket.

[0017] By opening a first limiting groove on the outer wall of the transmission roller, and opening a convex pattern perpendicular to the wire rope in the first limiting groove, and allowing the wire rope to pass through the first limiting groove, when the transmission roller rotates, the wire rope can be limited by the first limiting groove, and the friction with the wire rope can be increased by the convex pattern.

[0018] Preferably, a driving mechanism body is fixedly installed in the middle of the front end of the support frame, a driving sprocket is installed in the front end of the driving mechanism body, and a limiting plate is fixedly installed in a rectangular array on the upper surface of the support frame.

[0019] By fixing the limit plates in a rectangular array on the upper surface of the support frame, the size of the mold steel can be limited by two limit plates on the same side, thereby preventing the excessively wide mold steel from being placed incorrectly.

[0020] Preferably, the driven sprocket and the driving sprocket are connected via a transmission chain.

[0021] The driven sprocket and the driving sprocket are connected by a transmission chain, so that when the driving sprocket rotates, the two driven sprockets can be driven to rotate synchronously, thereby realizing the rotation of the two transmission rollers in the same direction.

[0022] Preferably, reserved grooves are respectively provided on both sides of the bottom of the landing gear, and the steel wire rope passes through the reserved grooves, and the landing gear is movably installed with the protective frame through an electric telescopic rod.

[0023] By opening reserved grooves on both sides of the bottom of the landing gear respectively and passing the steel wire rope through the reserved grooves, the sealing of the inner side of the protective frame is ensured while avoiding damage to the steel wire rope.

[0024] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0025] The utility model provides a landing gear and a transmission roller, and the transmission roller is rotatably installed at the two ends of the inner side of the support frame, and the two transmission rollers are connected by steel wire rope transmission, and the landing gear is movably installed on the outer side of the protection frame. When performing specific operations, the landing gear is raised by starting the electric telescopic rod, and the mold steel to be annealed can be placed on the steel wire rope on one side of the protection frame. By starting the driving mechanism body, the mold steel to be annealed can be moved to the upper surface of the base through the steel wire rope. At this time, the electric telescopic rod can be started again to make the landing gear fall down, and the inner space of the protection frame can be adjusted. A relative seal is performed, and then the starter body is started, so that the inner side of the protective frame is heated and kept warm by the resistance heater, and then the mold steel is annealed by slow cooling. When the current annealed mold steel needs to be taken out, the mold steel to be annealed is placed on the steel wire rope on one side of the protective frame, and the landing gear is raised. The mold steel to be annealed is moved to the upper surface of the base through the steel wire rope. At the same time, the mold steel that has been annealed is moved out from the other side above the base, so as to achieve the effect of loading new mold steel and unloading annealed mold steel at the same time, thereby improving work efficiency.
