Detailed Description
For better understanding of the technical solutions of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and specific embodiments thereof.
As shown in fig. 1 and 2, an embodiment of the present invention: a stamping forming furnace end supporting frame comprises a furnace end supporting frame 1, wherein the furnace end supporting frame 1 is formed by adopting a stamping process, supporting columns 2 are welded at four corners of the bottom of the furnace end supporting frame 1, the furnace end supporting frame 1 is flush with the bottoms of the supporting columns 2 after welding, then enamel surface treatment is carried out, mounting holes are formed in the bottoms of the supporting columns 2, and rubber pads 3 are fixed in the mounting holes; the whole rectangle frame structure that is of furnace end support frame 1, rectangular hole one has been seted up to the symmetry on furnace end support frame 1's the preceding back hypotenuse, rectangular hole two has been seted up to the symmetry on furnace end support frame 1's the left and right sides hypotenuse, furnace end support frame 1's top symmetry is provided with two furnace end support components.
The invention relates to a forming process for punch forming a furnace end support frame, which comprises the following steps:
(1) stretching the die: the method comprises the steps of installing and fixing a stretching forming die on a 300-ton first punching machine, taking prepared specification materials, coating special stretching lubricating oil on the specification materials, placing the specification materials on the stretching die (the upper surface of the die is provided with positioning, and the materials are placed according to the positioning), starting a switch, pressing the upper die downwards to reach the height required by a workpiece, and controlling the return stroke of the upper die by utilizing an infrared ray. The stretching is cold stretching, and the whole process is carried out from the step of placing the material on the mold to the step of stretching, and then the material is placed on the pallet for about 35 seconds. During stretching, the specific processing temperature is about 26 ℃, the pressure is 180 tons at 160 ℃, and the thickness of the used materials is different and the pressure is also different.
The lubricating oil is scientific lubricating oil with the model of CUT-312, consists of various extreme pressure, lubricating and antirust additives, has moderate viscosity, good adhesiveness and strong extreme pressure, and is used for stamping and drawing processing of medium and high strength steel, stainless steel and the like.

One set of die was used, but two sides were punched. The process is carried out from the step of discharging the materials on the die to the step of punching, and the process takes about 40 seconds after the materials are punched twice and then the materials are taken out and placed on the pallet.
c. Punching the front bevel edge and the rear bevel edge: and c, placing the workpiece processed in the step b on a fourth punching machine of 65 tons, and punching the strip holes on the front bevel edge and the rear bevel edge twice after adding the cutting fluid. One set of die was used, but two sides were punched. The process is carried out from material feeding to punching, and the material is taken out after two punching and then taken out and placed on the pallet for about 40 seconds
d. Flanging the top: and c, placing the workpiece processed in the step c on a top flanging die arranged on a 160-ton second punching machine, and adding lubricating oil to perform top flanging.
e. Flanging the left side and the right side: and d, placing the workpiece processed in the step d on left and right side flanging dies arranged on a third punching machine of 125 tons for side flanging. One set of die is adopted, but two sides are flanged twice. The process is carried out from the process of discharging the materials on the mould to the process of finishing the flanging and taking out the materials, and the process takes about 40 seconds when the materials are placed on the pallet.
f. Flanging the front and rear oblique edges: and e, placing the workpiece processed in the step e on front and rear side flanging dies arranged on a fourth punching machine of 65 tons, and adding lubricating oil to perform front and rear bevel edge flanging. One set of die is adopted, but two sides are flanged twice. The process is carried out from the process of discharging the materials on the mould to the process of finishing the flanging and taking out the materials, and the process takes about 40 seconds when the materials are placed on the pallet.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
