Description

Technical Field

[0001] The utility model belongs to the technical field of tool heat treatment, and in particular relates to a tool heat treatment complete set device. Background Art

[0002] In the production process of knives, heat treatment is the most critical core technology, which directly affects the product quality of knives and scissors. Appropriate heat treatment can eliminate various defects caused by hot processing processes such as casting, forging, and welding, refine grains, eliminate segregation, reduce internal stress, and make the organization and performance of steel more uniform. The traditional heat treatment process of knife and scissors blanks mainly improves the hardness and toughness of steel, and cannot further process the flatness of the knife blank, thereby failing to further improve the quality of the knife.

[0003] The existing patent (publication number: CN206843541U) discloses a complete set of heat treatment equipment for cutting tools, including a heating system and a cooling system. The heating system transmits the cutting tool blank through a rotating wheel and a conveyor belt, and heats it in a heating box. During the heating process, ammonia is continuously filled into the heating box to drive away the oxygen in the device to ensure that the cutting tool blank is not oxidized. The hydrogen formed by the decomposition of ammonia by heat is burned in the exhaust gas combustion furnace. The heated cutting tool blank is cooled by the cooling system. During cooling, the cutting tool blank is placed between the upper mold and the lower mold. The cooling water cools the cutting tool blank through the water channels of the upper and lower molds. At the same time, the upper and lower molds press the cutting tool blank tightly to make the cutting tool blank smoother.

[0004] The above-mentioned comparative document points out that the device involved performs heat treatment on the knives and scissors, and the surfaces of the knives and scissors are smoother and have higher hardness. However, the device is not provided with a demolding structure. When the upper and lower molds are used to level the cutter, under the action of pressure, the cutter will be leveled and will also fit tightly with the lower mold. The lack of a demolding structure will make it difficult to remove the leveled cutter. Therefore, a set of cutter heat treatment equipment is proposed to solve the above-mentioned problem. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a set of tool heat treatment equipment, which has the advantages of improved heating effect and convenient removal of the flattened tool from the mold. It solves the problem pointed out in the above-mentioned comparative document that the device is not provided with a demolding structure. When the upper and lower molds are used to level the tool, under the action of pressure, the tool will be leveled and will also fit tightly with the lower mold. The lack of a demolding structure will make it difficult to remove the flattened tool.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a complete set of tool heat treatment equipment, comprising a first workbench, two seals and a second workbench, two base plates are fixedly provided on the upper end of the first workbench, heating boxes are fixedly provided on the upper ends of the two base plates, fixed columns are fixedly provided on both sides of the heating boxes, L-shaped adjustment cavities are penetrated through the insides of the two seals, the two fixed columns slide respectively in the insides of the two L-shaped adjustment cavities, and operating rods are fixedly provided on one side of the two seals.

[0007] Baffles are fixedly provided on both sides of the upper ends of the two base plates, two rotating rollers are rotatably provided between the two baffles, and the outer walls of the two rotating rollers are sleeved with conveyor belts, and a driven wheel is fixedly provided on the outer wall of one end of the rotating rollers extending out of the baffle, and a motor is fixedly provided on the upper end of one of the base plates through a fixed plate, and the output end of the motor extends out of the fixed plate and is fixedly sleeved with a driving wheel, and the outer walls of the driving wheel and the driven wheel are sleeved with belts.

[0008] Through the above scheme, the device is equipped with a fixed column, a seal, an L-shaped adjustment cavity and an operating rod. When the conveyor belt transports the tool to the bottom end of the heating box, the seal is moved by the operating rod to adjust the position of the fixed column in the L-shaped adjustment cavity, thereby sealing the gaps between the two sides of the heating box and the upper and lower parts of the conveyor belt, which can reduce heat loss and improve the efficiency of heat treatment.

[0009] Furthermore, a temperature adjustment knob is fixedly provided on one side of the heating box, and the temperature adjustment knob is electrically connected to the heating box.

[0010] Through the above scheme, the temperature control knob is used to adjust the temperature in the heating box.

[0011] Furthermore, a blocking piece is fixedly provided on one side of the two fixing columns.

[0012] Through the above solution, the blocking piece is used to prevent the seal from being separated from the fixing column.

[0013] Furthermore, a guide plate is fixedly disposed inside one end of the two baffles.

[0014] Through the above solution, the tool that has completed heat treatment flows directly to the second workbench through the guide plate under the action of the conveyor belt. The operator can directly put the tool into the lower mold for leveling, reducing the intermediate clamping steps and improving efficiency.

[0015] Furthermore, a first support frame is fixedly provided on the upper end of the second workbench, a first hydraulic push rod is fixedly provided on the lower end of the first support frame, and an upper mold is fixedly provided on the output end of the first hydraulic push rod.

[0016] Through the above solution, the output end of the first hydraulic ejector rod moves downward to drive the upper mold to move downward, thereby allowing the upper mold to level the tool in the mold cavity of the lower mold.

[0017] Furthermore, a lower mold is fixedly arranged at the bottom end of the second workbench, and a push plate is slidably arranged inside the mold cavity of the lower mold.

[0018] Through the above scheme, the tool after heat treatment is placed in the lower mold, and the push plate is used to push out the flattened tool.

[0019] Furthermore, the bottom end of the push plate is fixedly connected to the output end of the second hydraulic push rod, the bottom end of the second hydraulic push rod is fixedly connected to the second support frame, and one end of the second support frame is fixedly connected to the second workbench.

[0020] Through the above solution, the second hydraulic ejector is the driving structure of the demoulding structure.

[0021] Furthermore, legs are fixedly provided around the bottom ends of the first workbench and the second workbench.

[0022] Through the above solution, the legs support the first workbench and the second workbench and raise their heights, making it convenient for workers to operate.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The tool heat treatment complete set device is provided with a fixed column, a seal, an L-shaped adjustment cavity and an operating rod. When the conveyor belt conveys the tool to the bottom end of the heating box, the seal is moved by the operating rod, and then the position of the fixed column in the L-shaped adjustment cavity is adjusted, and then the gap between the two sides of the heating box and the upper and lower parts of the conveyor belt is sealed, which can reduce heat loss and improve the efficiency of heat treatment. By providing a second hydraulic ejector and a push plate, it is convenient to take out the tool. After the tool is leveled, the tool and the lower mold are closely fitted. By providing a demoulding structure, after the leveling is completed, the output end of the second hydraulic ejector rises, and then the push plate rises, so that the push plate pushes the tool out of the cavity of the lower mold.
