Description

Technical Field

[0001] The invention relates to the technical field of steel processing, in particular to a drawing device for processing alloy stainless steel profiles. Background Art

[0002] Stainless steel profiles are used in engineering construction, thanks to their excellent corrosion resistance, enabling structural components to permanently maintain the integrity of engineering designs. Chromium-containing stainless steel also combines mechanical strength and high ductility, making it easy to fabricate components and meeting the needs of architects and structural designers. Following the success of its initial practical application, stainless steel profiles are now available in standard sizes of stainless steel angles, flat bars, and square bars.

When there is wear or damage inside, the profile mold cannot be used and requires more materials for repair or replacement; 2. During the forming process of stainless steel, the stainless steel in the molten state is prone to blockage problems, and some muddy stainless steel cannot be used and accumulates and compresses inside the equipment.

DETAILED DESCRIPTION

[0047] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0048] See also Figures 1 to 13 , the present invention provides a technical solution: Figure 1 、 Figure 2 and Figure 3 As shown, it includes an alternative mechanism 7 for selecting and processing different profile molds. A double-head frame 2 is provided on the outside of the alternative mechanism 7, and a frame plate 1 is fixedly connected to the bottom of the double-head frame 2;

[0049] A hydraulic cylinder 3 is fixedly installed on the outside of the double-head frame 2, and the output end of the hydraulic cylinder 3 is inserted into one end of the double-head frame 2;

[0050] A transition frame 4 is fixedly installed on the inner side of the double-head frame 2;

[0051] The traction platform 5 is used for limiting the traction of the stainless steel pipe. The traction platform 5 is fixedly installed on the transition frame 4.

[0052] The bottom of the inner cavity of the transition frame 4 is fixedly connected to the No. 1 rail 6 , and the end surface of the No. 1 rail 6 is fixedly connected to the limit plate 8 .

[0053] The alternative mechanism 7 includes an external frame 71, which is fixedly connected to the outer side of the double-head frame 2, and a rotating platform 72 is rotatably mounted on the bottom of the external frame 71;

[0054] The top of the rotating platform 72 is fixedly connected to the second rail 73;

[0055] The outer side of the sleeve frame 74 is sleeved with an inserting frame 75 , and the bottoms of the sleeve frame 74 and the inserting frame 75 are both slidably adapted to the second rail 73 ;

[0056] The interior of the sleeve frame 74 is respectively provided with a No. 1 forming component 76 and a No. 2 forming component 77. When the operator rotates the rotating table 72 in the forward direction, the No. 2 rail 73 fixedly connected to the top thereof will rotate, and the top of the No. 2 rail 73 is slidably adapted with the sleeve frame 74, wherein the number of the No. 2 rail 73, the sleeve frame 74 and the insert frame 75 are all two, and the interiors of the two sleeve frames 74 and the insert frame 75 are both provided with a No. 1 forming component 76 and a No. 2 forming component 77. Therefore, by rotating the rotating table 72, one of the predetermined No. 2 rails 73 can be selected and placed on the same horizontal line with the No. 1 rail 6, and then the sleeve frame 74 and the insert frame 75 on the No. 2 rail 73 are respectively moved along the No. 2 rail 73 and the No. 1 rail. 6 enters the transition frame 4 until it is restricted by the limit plate 8. Finally, the center parts of the No. 1 forming component 76 and the No. 2 forming component 77 will coincide with the center parts of the traction table 5, the transition frame 4 and the double-head frame 2 respectively, thereby playing a role in quickly replacing profile molds of different shapes. At the same time, two identical profile molds can be placed on the two No. 2 rails 73, so that when one of the profile molds is blocked or worn during the processing, the other profile mold can be quickly replaced for replacement processing, thereby playing a role in alternating replacement processing between the same profile molds, and always maintaining the processing effect of the profile.

[0057] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown, the No. 1 molding assembly 76 includes a No. 1 sleeve joint 81 , and the outer end surface of the No. 1 sleeve joint 81 is fixedly connected to a compensation mold 82 ;

[0058] An internal threaded tube 83 is inserted into the outer end face of the No. 1 sleeve joint 81, and the internal thread of the internal threaded tube 83 is connected to a screw 84, and the outer side of the screw 84 is fixedly connected to a fixed sleeve 85, and the outer side of the fixed sleeve 85 is extruded and adapted with a bearing 86; the inner wall of the internal threaded tube 83 has threads only on a small section close to the screw 84, and the part where the screw 84 is connected to the fixed sleeve 85 is not threaded, and the rest are all threads.

[0059] An external connecting ring 87 is fixedly connected to the inner side of the insertion frame 75;

[0060] The insert head 88 is used to limit the external ring 87 and the insertion frame 75. The insert head 88 is fixedly connected to the side of the external ring 87 away from the insertion frame 75. The end of the insert head 88 away from the external ring 87 is fitted with the No. 1 socket 81;

[0061] The internal threaded tube 83 is inserted into the surface of the second sleeve 91 and extends into the interior thereof. Notches 801 are symmetrically formed on both sides of the internal threaded tube 83.

[0062] The rod connector 89 is rotatably connected to the outer side of the screw rod 84, and the interior of the rod connector 89 is fixedly connected to the first magnetic block 80;

[0063] A return spring 802 is fixedly connected to the interior of the second sleeve joint 91. The end of the return spring 802 away from the second sleeve joint 91 is fixedly connected to the slider 803. The return spring 802 is used to reset the slider 803.

[0064] An extension block 804 is fixedly connected to one end of the slider 803 away from the return spring 802;

[0065] The second magnetic block 805 and the first magnetic block 80 attract each other. When the second magnetic block 805, the first magnetic block 80 and the notch 801 are in the same straight line, the second magnetic block 805 will bring the extension block 804 to fit into the notch 801 under the action of magnetic attraction. Next, the stainless steel rod to be processed is placed inside the traction platform 5. The hydraulic cylinder 3 is then activated, inserting its output end into the traction platform 5 and pushing the stainless steel rod inward, causing it to move along the traction platform 5 and the transition frame 4 until it enters the space enclosed by the sleeve frame 74 and the insert frame 75. The sleeve frame 74 and the insert frame 75 fit together perfectly. The inner wall of the sleeve frame 74 is connected to the second sleeve joint 91, while the inner side of the insert frame 75 is connected to the external connecting ring 87. Therefore, when the operator rotates the fixed sleeve 85 counterclockwise, the screw 84 connected to it will spiral outward along the internal threaded tube 83. The outer side of the fixed sleeve 85 is connected to the external connecting ring 87 via a bearing 86. A rod connector 89 is rotatably mounted on the screw 84, and the inner side of the rod connector 89 is connected to the first magnetic block 80. The rod connector 89 is heavy enough to prevent deflection. As the rod connector 89 moves outward, the No. 1 magnetic block 80 is no longer in the same straight line with the notch 801 and the No. 2 magnetic block 805. Therefore, the attraction between the No. 1 magnetic block 80 and the No. 2 magnetic block 805 will be blocked, and the extension block 804 connected to the No. 2 magnetic block 805 will pass through the slider 803 and be received in the No. 2 sleeve joint 91 under the compression force of the return spring 802. At the same time, the extension block 804 will also extend outward from the notch 801 and will no longer limit the internal threaded tube 83, thereby playing the role of quickly separating the No. 2 sleeve joint 91 and the No. 1 sleeve joint 81. Compared with the one-piece mold, when a certain part inside it is damaged, only the sleeve joint associated with that part needs to be replaced, and the other sleeve joint can continue to be used, thereby playing the role of quick separation, quick installation and cost reduction.

[0066] The second forming assembly 77 includes a second sleeve joint 91, which is fixedly installed inside the sleeve frame 74, wherein the second sleeve joint 91 and the first sleeve joint 81 are fitted with each other and assembled into a structure for drawing and forming stainless steel profiles.

[0067] The inner side of the No. 2 sleeve joint 91 is fixedly connected to the No. 1 mold 92, and the bottom of the No. 2 sleeve joint 91 is provided with a liquid outlet 94;

[0068] The second mold 93 is fixedly connected to the first mold 92, and a gap is left in the center of the second mold 93 and the first sleeve 81;

[0069] The outer side of the No. 1 mold 92 is fixedly connected to the No. 3 rail 95, and the inner sliding adapter of the No. 3 rail 95 is equipped with a shift block 96. The side of the shift block 96 away from the No. 3 rail 95 is fixedly connected to a limiting plate 97, wherein the two ends of the limiting plate 97 are slidably adapted to the No. 1 sleeve 81 and the No. 1 mold 92 respectively. The bottom of the shift block 96 is fixedly connected to a driving telescopic rod 98, and the driving telescopic rod 98 is fixedly connected to the inner side of the No. 2 sleeve 91. Then the stainless steel rod will hit the combined form of mold No. 1 92 and mold No. 2 93 respectively. Because the stainless steel rod needs to be heated and softened during the drawing process, the hardness of the stainless steel rod is much smaller than that of mold No. 1 92 and mold No. 2 93, and it has a certain toughness. At this time, the stainless steel rod will be compressed and become muddy, and move outward from the space enclosed by the inner cavity of mold No. 2 93 and the No. 1 sleeve joint 81. The shape of the inner cavity of the No. 1 sleeve joint 81 matches the outer surface of the required molded profile. Finally, the muddy stainless steel material will be reshaped between mold No. 2 93 and sleeve joint No. 1 81, and initially form the shape of the required profile, and then be discharged outward from the compensation mold 82 and the insertion frame 75 in turn. In addition, when the stainless steel rod is compressed and becomes muddy, the subsequent stainless steel rods that have not been squeezed will push the muddy stainless steel to accumulate and compress between the No. 1 mold 92 and the No. 2 mold 93. If the force of the accumulation and compression is too large, the muddy stainless steel will squeeze the flow limiting plate 97, and the squeezed flow limiting plate 97 will move outward along the No. 3 track 95 through the shift block 96 and compress the drive telescopic rod 98. The four flow limiting plates 97 are initially formed into a circle and prevent the muddy stainless steel from overflowing. However, as the flow limiting plates 97 move outward, a gap will appear in the circle. At this time, part of the muddy stainless steel will overflow, thereby relieving the pressure of the muddy stainless steel that has been accumulated and compressed too much, and avoiding damage to the internal part of the equipment caused by excessive accumulation.

[0070] The bottom of the flow limiting plate 97 is fixedly connected to a bottom connecting rod 99, and an inner connecting head 901 is provided directly below the bottom connecting rod 99. The inner connecting head 901 is fixedly connected to the top of the liquid outlet 94, and the outer side of the inner connecting head 901 is appropriately embedded with a blocking plate 90. The bottom of the blocking plate 90 is fixedly connected to a reset telescopic rod 902, and the bottom of the reset telescopic rod 902 is fixedly connected to a strap plate 903, which is fixedly connected to the inner wall of the liquid outlet 94. When irregular accumulation and compression occur, or blockage occurs inside the equipment, the four flow limiting plates 97 will continue to move outward along the No. 3 track 95, and the bottom connecting rod 99 fixedly connected to the bottom of the lower flow limiting plate 97 will also move downward and squeeze the blocking plate 90. The squeezed blocking plate 90 will compress the resetting telescopic rod 902 and intersect with the inner connecting head 901. Then, the excess muddy stainless steel will be discharged outward along the liquid outlet 94, thereby increasing the pressure relief treatment of the muddy stainless steel and reminding the operator that there is a problem with the equipment.

[0071] When the present invention is in use: first, the operator rotates the rotating table 72 in the forward direction, causing the No. 2 rail 73 fixedly connected to its top to rotate, and the top of the No. 2 rail 73 is slidably adapted with a sleeve frame 74, wherein the number of the No. 2 rail 73, the sleeve frame 74 and the insertion frame 75 is two, and the interiors of the two sleeve frames 74 and the insertion frames 75 are both provided with a No. 1 forming component 76 and a No. 2 forming component 77. Therefore, by rotating the rotating table 72, one of the predetermined No. 2 rails 73 can be selected and placed on the same horizontal line as the No. 1 rail 6, and then the sleeve frame 74 and the insertion frame 75 on the No. 2 rail 73 are respectively entered into the transition frame 4 along the No. 2 rail 73 and the No. 1 rail 6 until they are restricted by the limit plate 8, and finally the center parts of the No. 1 forming component 76 and the No. 2 forming component 77 will coincide with the center parts of the traction table 5, the transition frame 4 and the double-head frame 2 respectively. Then, the stainless steel rod is placed into the interior of the traction platform 5, and then the hydraulic cylinder 3 is started so that its output end is inserted into the traction platform 5 and pushes the stainless steel rod inward.

[0072] The stainless steel rod is squeezed by the output end of the hydraulic cylinder 3, causing it to enter the space surrounded by the sleeve frame 74 and the insertion frame 75 along the traction table 5 and the transition frame 4 respectively, and then the stainless steel rod will respectively collide with the combination of mold No. 1 92 and mold No. 2 93. Because the stainless steel rod needs to be heated and softened during the drawing process, the hardness of the stainless steel rod is much smaller than the hardness of mold No. 1 92 and mold No. 2 93, and has a certain toughness. At this time, the stainless steel rod will be compressed and become muddy, and move outward from the space surrounded by the inner cavity of mold No. 2 93 and the No. 1 sleeve joint 81, where the shape of the inner cavity of the No. 1 sleeve joint 81 matches the outer surface of the required formed profile. Finally, the muddy stainless steel material will be reshaped between mold No. 2 93 and sleeve joint 81, and initially form the shape of the required profile, and then be discharged outward from the compensation mold 82 and the insertion frame 75 in turn. In addition, when the stainless steel rods are compressed and become muddy, the subsequent stainless steel rods that have not been squeezed will push the muddy stainless steel to accumulate and compress between the No. 1 mold 92 and the No. 2 mold 93. If the force of the accumulation and compression is too large, the muddy stainless steel will squeeze the flow limiting plate 97, and the squeezed flow limiting plate 97 will move outward along the No. 3 track 95 through the shift block 96 and compress the telescopic rod 98. The four flow limiting plates 97 are initially formed into a circle and prevent the muddy stainless steel from overflowing. However, as the flow limiting plates 97 move outward, a gap will appear in the circle, and at this time, part of the muddy stainless steel will overflow outward, so as to achieve the dumping treatment of excessive muddy stainless steel.

[0073] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
