Description

Technical Field

[0001] The invention relates to the field of angle steel forming processing, in particular to a die-pressing forming device for angle steels of multiple specifications. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other at an angle. It is divided into equal-leg angle steel and unequal-leg angle steel. The cross-section of angle iron is a long steel strip with two sides perpendicular to each other at a right angle. Angle iron is divided into equal-leg angle steel and unequal-leg angle steel. The two vertical sides are the same length for equal-leg angle steel, and one long and one short for unequal-leg angle steel. SMC is a molded intermediate material for dry-process manufacturing of fiberglass products. It is pre-mixed into a paste with unsaturated polyester resin, low shrinkage, low profile additives, initiator, internal release agent, mineral filler, etc., and then mixed with thickener and other ingredients. After mixing evenly, the chopped glass fiber is fully impregnated to form a sheet-like sandwich structure. The SMC molding process is one of the most advanced and important fiberglass forming methods.

[0003] When adopting the molding process to produce angle steel, it is necessary to manually place the raw materials of the sandwich structure in the mold. Due to the high temperature of the mold, when placing the raw materials manually, on the one hand, the high temperature can easily burn the workers, which is dangerous. In addition, the raw materials need to be prepared immediately for placement. During the raw material preparation process, the mold is in a stopped state, which is relatively time-consuming. On the other hand, when placing the raw materials on the mold, the raw materials need to be heated by the mold. During the die-casting process, more time is required, which reduces the die-casting efficiency of the angle steel.

[0004] Therefore, based on the above problems, we invented a die-forming device for angle steels of multiple specifications. Summary of the Invention

[0028] In the present invention, a fixed motor 49 is fixedly installed outside the placement frame 27. The driving shaft of the fixed motor 49 rotates and passes through the placement frame 27 and is coaxially installed with the fixed shaft 33. Two rotating shafts 34 are provided under the placement frame 27. A rotating plate 37 is fixedly sleeved outside the rotating shaft 34. An electric heating plate is embedded in the rotating plate 37. A fixed block 35 is rotated outside the rotating shaft 34. The fixed block 35 is fixedly installed with the placement frame 27. One end of the two rotating shafts 34 rotates and passes through the two fixed blocks 35 and is connected through a residual gear set 38.

[0030] Through the above technical features: the placing frame 27 is placed just above the lower mold 4 by the robotic arm 26, the two rotating shafts 34 are driven to rotate relative to each other by the rotating motor 36, and the two rotating shafts 34 drive the two rotating plates 37 to rotate, so that the sandwich raw material placed on the rotating plate 37 falls directly onto the lower mold 4, and the rotating plate 37 is closed at this time, and the two moving screws 41 are driven to rotate by the moving motor 40, and the moving screw 41 drives the thread block 42 to move, and the thread block 42 drives the V-shaped plate 43 to move, and the V-shaped plate 43 drives the pressing roller 44 to move, and the pressing roller 44 presses the sandwich raw material tightly to make it close to the lower mold 4. During molding, the raw material will not be offset, and the placement of the raw material is more convenient and stable; when the raw material on the rotating plate 37 After the material is placed, the fixed motor 49 drives multiple fixed shafts 33 to rotate, and the fixed shafts 33 drive the partition 28 to rotate. During the rotation of the partition 28, the sandwich raw materials placed on the partition 28 fall down a layer under the action of gravity. At this time, raw materials are added again on the rotating plate 37 layer, and the raw materials are preheated by the electric heating plate in the rotating plate 37. On the one hand, there is no need for manual placement when placing the raw materials, and the safety is higher. On the other hand, the raw materials can be preheated in the placement frame 27, which reduces the heating time of the raw materials in the mold and improves the die-casting efficiency of the angle steel. During the die-casting process, the raw materials can be prepared and placed in the placement frame 27, which improves time utilization and increases the production efficiency of the angle steel.

[0031] Working principle: (1) Adjusting the size of the die-cast angle steel: The two adjusting screws 9 are driven to rotate by the adjusting motor 12, and the two adjusting screws 9 drive the adjusting sleeve 11 to move, and the adjusting sleeve 11 drives the adjusting plate 10 to move until it reaches the appropriate position. The rotating shaft 19 is driven to rotate by the pushing motor 24, and the rotating shaft 19 drives the two pushing screws 50 to rotate, and the pushing screw 50 drives the threaded sleeve 18 to move, and the threaded sleeve 18 drives the L-shaped plate 46 to move, and the L-shaped plate 46 drives the longitudinal pad 16 to move until it reaches the appropriate position, thereby adjusting the placement position of the transverse pad 15. (2) Placing the raw materials: Place the cut raw materials in the placement frame 27 and transport the raw materials to the rotating plate 37. The raw materials are preheated by the electric heating plate in the rotating plate 37. When the mold is opened, the placement frame 27 is placed directly above the lower mold 4 by the robot arm 26. The two rotating shafts 34 are driven to rotate relative to each other by the rotating motor 36. The two rotating shafts 34 drive the two rotating plates 37 to rotate, so that the sandwich raw materials placed on the rotating plates 37 fall directly onto the lower mold 4. At this time, the rotating plate 37 is closed and the two moving screws 41 are driven to rotate by the moving motor 40. The moving screws 41 drive the thread block 42 to move. The thread block 42 The V-shaped plate 43 is driven to move, and the V-shaped plate 43 drives the pressure roller 44 to move. The pressure roller 44 presses the sandwich raw material tightly to make it close to the lower mold 4. When the raw material on the rotating plate 37 is placed, the fixed motor 49 drives multiple fixed shafts 33 to rotate, and the fixed shaft 33 drives the partition 28 to rotate. During the rotation of the partition 28, the sandwich raw material placed on the partition 28 falls down a layer under the action of gravity. At this time, raw materials are added to the rotating plate 37 layer again, and the raw materials are preheated by the electric heating plate in the rotating plate 37. After loading is completed, the placement frame 27 is moved out by the robot arm 26 for mold closing and die casting, and raw materials are prepared.
