Description

Technical Field

[0001] The invention relates to the technical field of spring forging, in particular to a heat treatment and forging integrated machine for spring forming. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. Different types of springs require different production equipment. Springs used as large-scale carriers are larger in size, so larger twisting equipment is needed to force the preheated steel into shape.

[0003] At present, large-size springs need to be preheated before processing. During the preheating process, the liner for conveying protective gas in the preheating furnace is too large. Therefore, most preheating furnaces directly preheat the steel. However, this direct preheating will cause impurities on the surface of the steel to oxidize and form a black film. This black film will cause wear on the steel body during the twisting process of the steel. As the internal stress of the steel continues to increase, the wear wounds on the surface of the steel will be compressed and form cracks.

[0004] In view of the above, the present invention designs a spring forming heat treatment and forging integrated machine to solve the above problems. Summary of the invention

[0009] In a preferred example, the present invention can be further configured as follows: the traction bearing mechanism further includes a bottom clamping rod installed in the slide seat, a guide installed on the bottom clamping rod, and a reinforcing spring arranged outside the stress relief pressing piece; The bottom clamping rod is composed of a U-shaped shell and a rotating wheel.

[0010] In a preferred example, the present invention can be further configured as follows: the beam frame is composed of a cushion block and a guide rod, and the guide rod is provided with evenly distributed sockets inside, and the sockets are movably provided with latches inside.

[0011] In a preferred example, the present invention can be further configured as follows: the stress-relieving pressing piece is composed of an elliptical pad and a support rod, and a nut is movably installed on the threaded section at the top of the support rod, and a plurality of evenly distributed annular grooves are formed at the bottom of the elliptical pad.

[0012] In a preferred example, the present invention can be further configured as follows: the pressure-bearing assembly includes a support plate arranged on the guide rod, two clamps installed on the support plate, a limit guide rod movably installed between the two clamps, and a compression spring arranged outside the limit guide rod; A concave hole is formed at one end of the support plate away from the guide rod.

[0014] In a preferred example, the present invention can be further configured as follows: the annular scraper assembly includes two protective shells, a heat-insulating inner pad installed inside the protective shells, a partition fixedly installed outside the protective shells, a pressure-resistant rotor movably installed between the two protective shells, a plurality of scraping heads fixedly installed on the inner wall of the pressure-resistant rotor, four stabilization ducts arranged between the two protective shells, and a fixed column that penetrates into the stabilization duct and is installed on the two protective shells.

[0025] The shaping mechanism 100 includes a first hydraulic component 140 which is horizontally placed and rolls up the preheated steel, a base 110 which is mounted on the outer end of the first hydraulic component 140 through a bearing, a twisting roller 120 which is mounted on one end of the first hydraulic component 140 through a clamp, a clamping seat 130 which is mounted on the twisting roller 120, a bearing column 150 which is mounted on the outside of one of the bases 110, and a second hydraulic component 160 which is installed in the bearing column 150 and is horizontally placed; The clamping seat 130 is an L-shaped structure as a whole, and a rectangular pad is installed at the bottom of the clamping seat 130, and a ring groove for clamping steel is opened at the bottom of the rectangular pad; The traction bearing mechanism 200 includes a slide 210 movably mounted outside the first hydraulic component 140, a top clamping rod 270 mounted on the slide 210, a stress relief pressing member 280 movably mounted in the top clamping rod 270, a beam frame 220 mounted outside the slide 210, and a pressure bearing assembly 230 mounted outside the beam frame 220; A bottom plate 310 installed in the pressure-bearing assembly 230 , an annular scraper assembly 390 installed on the bottom plate 310 , a bracket 350 installed in the bottom plate 310 , and two calibrated end pipes 360 installed on the bracket 350 .

[0026] Before large-sized steel is processed into large springs through rollers, it needs to be preheated in a preheating furnace. However, during the preheating process, black dirt and impurities are easily generated on the surface of the steel during the heating process. If the steel is directly guided to the roller and twisted along the outer spiral of the roller, the black dirt will be pressed by the roller, and the steel itself will be deformed under pressure and will rub against the black dirt. In severe cases, it will cause wear on the surface of the steel. As the spring gradually takes shape, the worn parts will form cracks due to the increase in pressure and distortion, thereby affecting the quality of the formed spring.

[0027] Therefore, when the device is in use, by setting two calibration end tubes 360 of the same size as the steel, after one end of the preheated steel passes through the two calibration end tubes 360 and extends into the interior of the protective shell 391 and the anti-pressure rotating wheel 394, the multiple scraping heads 395 evenly distributed on the inner wall of the anti-pressure rotating wheel 394 can adapt to the steel itself. When the black dirt layer exceeds the thickness of the steel itself, the anti-pressure rotating wheel 394 driven by the linkage gear 380 and rotating at a high speed will drive the multiple scraping heads 395 to scrape off the black dirt, thereby not causing damage to the steel itself, and as the steel is delivered to the twisting After the top of the rotating roller 120 is clamped by the clamping seat 130, as the twisting roller 120 rotates, the cleaned steel can be spirally twisted along the outside of the twisting roller 120, and the guide 260 will provide lateral traction to the steel. As the spring is gradually formed, the stress relief pressure piece 280 set in the top clamping rod 270 can adapt and fit the spring. Under the action of the high-intensity pressure of the reinforcing spring 290, the stress relief pressure piece 280 can provide forced compression molding for the spring. In conjunction with the high-temperature processing environment, the stress relief pressure piece 280 can eliminate the stress inside the spring after forming. Embodiment 2:

[0028] Combination Figure 2-Figure 4 As shown, based on the first embodiment, the traction bearing mechanism 200 further includes a bottom clamping rod 250 installed in the slide 210, a guide 260 installed on the bottom clamping rod 250, and a reinforcing spring 290 arranged outside the stress relief pressing piece 280; The bottom clamping rod 250 is composed of a U-shaped housing and a rotating wheel; The beam frame 220 is composed of a cushion block and a guide rod, and the guide rod is provided with evenly distributed plug holes inside, and the plug holes are movably installed with a latch 240; The stress relief pressing piece 280 is composed of an elliptical pad and a support rod, and a nut is movably installed on the threaded section at the top of the support rod, and a plurality of evenly distributed annular grooves are opened at the bottom of the elliptical pad; The pressure bearing assembly 230 includes a support plate 231 disposed on the guide rod, two clamps 233 mounted on the support plate 231, a limiting guide rod 234 movably mounted between the two clamps 233, and a compression spring 235 disposed outside the limiting guide rod 234; A recessed hole 232 is formed at one end of the support plate 231 away from the guide rod.

[0029] When the cup clamp seat 130 at one end of the cleaned steel is fixed on the outside of the twisting roller 120, as the twisting roller 120 rotates, the cleaned steel can be spirally twisted along the outside of the twisting roller 120. At the same time, the hydraulic sub-rod in the second hydraulic component 160 drives the slide 210 to move stably along the outside of the twisting roller 120, and the guide component 260 fixed by the bottom clamp rod 250 can provide the steel with traction energy for spiral twisting, and cooperate with the stress relief pressing component 280 to apply downward pressure on the top of the spiral steel, so that the stress inside the spring after forming can be eliminated. Embodiment three:

[0030] Combination Figure 5-Figure 7 As shown, based on the first embodiment, the wall scale micro-cleaning mechanism 300 further includes a guide member 320 movably mounted in the bottom plate 310, a chassis 330 fixedly mounted on the top of the bottom plate 310, a motor 340 mounted in the chassis 330, a chain 370 driven on the transmission shaft gear in the motor 340, and a linkage gear 380 driven at the other end of the chain 370; The annular scraper assembly 390 includes two protective shells 391, a heat-insulating inner pad 392 installed inside the protective shells 391, a partition 393 fixedly installed outside the protective shells 391, a pressure-resistant rotating wheel 394 movably installed between the two protective shells 391, a plurality of scraping heads 395 fixedly installed on the inner wall of the pressure-resistant rotating wheel 394, four stabilizing ducts 396 arranged between the two protective shells 391, and a fixing column 397 penetrating into the stabilizing duct 396 and installed on the two protective shells 391; The outer portion of the anti-pressure rotating wheel 394 is provided with a tooth opening, and the tooth opening of the outer portion of the anti-pressure rotating wheel 394 is adapted to mesh with the linkage gear 380; The inner wall of the pressure-resistant rotating wheel 394 is provided with a plurality of evenly distributed holes.

[0031] The base plate 310 is movably installed in the recessed hole 232, and is movably installed in the guide member 320 in the base plate 310, and the limiting guide rod 234 penetrates into the interior of the guide member 320. At the same time, under the elastic pressure of the compression spring 235, once the steel material applies pressure to the two calibration end tubes 360 and causes the base plate 310 to rotate, the limiting guide rod 234 and the compression spring 235 can provide a stable supporting force for the guide member 320 to avoid the problem of excessive rotation angle of the base plate 310 due to the increase of steel pressure. At the same time, the internal transmission shaft of the running motor 340 will cooperate with the chain 370 to drive the linkage gear 380, and the high-speed rotating anti-pressure wheel 394 can combine with multiple scraping heads 395 to mechanically scrape off the black dirt on the surface of the steel.

[0032] The working principle and use process of the present invention are as follows: a plurality of scraping heads 395 are uniformly installed in the plurality of holes on the inner wall of the pressure-resistant rotating wheel 394 in advance, and the blades of the plurality of scraping heads 395 are oriented toward the center of the circle of the pressure-resistant rotating wheel 394. Then, two protective shells 391 are movably installed at the two ends of the pressure-resistant rotating wheel 394, and then the two protective shells 391 are fixed by using four pressure-resistant rotating wheels 394 and four fixing columns 397. The two heat-insulating inner pads 392 installed on the inner walls of the two protective shells 391 can be symmetrical with the holes of the pressure-resistant rotating wheel 394. At this time, the two protective shells 391 are connected to each other. The movable gear 380 is movably installed in the gap between the two partitions 393, and the gear at one end of the linkage gear 380 is located outside one of the partitions 393. Then, the two combined protective shells 391 are fixedly installed on the top of the bottom plate 310, and the motor 340 fixed to the bottom plate 310 through the chassis 330, the gear on the internal transmission shaft and the gear on the linkage gear 380 are connected by the chain 370, and the bracket 350 is fixedly installed in the horizontal groove at one end of the bottom plate 310. At this time, the two calibration end tubes 360 are fixed respectively. The bottom plate 310 is then movably mounted in the concave hole 232, and the other end of the bottom plate 310 is movably mounted on the pressure-bearing component 230 and movably mounted on the outside of the limiting guide rod 234. The compression spring 235 arranged on the outside of the limiting guide rod 234 has one end away from the chuck 233 pressed against the end surface of the guide member 320. When the preheated steel enters the two calibration end tubes 360 and the pressure-resistant wheel 394, the bottom plate 310 is movably mounted in the concave hole 232, and the other end of the bottom plate 310 is movably mounted on the pressure-bearing component 230 and movably mounted on the outside of the limiting guide rod 234. After the wheel 394 is inside, the steel material that is in tension and running in stretching will be compressed and act on the bottom plate 310. In order to reduce the interference of the calibration end tube 360 ​​on the steel material, the bottom plate 310 as a whole can rotate along the outside of the limit guide rod 234. At this time, the support plate 231 is fixed to the rod body of the beam frame 220 by the pin 240. At this time, the pressure-bearing component 230 as a whole can provide a sufficiently safe discharge gap for the wall scale micro-cleaning mechanism 300 to avoid the gap between the bottom plate 310 as a whole and the first hydraulic component 140 being too small to cause the preheated steel material to tilt. When in use, when one end of the preheated steel is pulled by the pliers and extends along one of the calibration end tubes 360, until the steel passes through the support of the two heat-insulating inner pads 392 and finally extends out of the other calibration end tube 360, the hole inside the pressure-resistant wheel 394 can maintain a safe gap with the steel, and the multiple scraping heads 395 installed on the pressure-resistant wheel 394 can have a blade that adapts and fits along the black dirt on the surface of the steel. When the dirt accumulates on the surface of the steel and its thickness exceeds the thickness of the steel itself, the blade of the scraping head 395 can perform circular scraping on the black dirt on the steel that is stretched out at a uniform speed, and the end of the steel with the black dirt scraped off needs to be delivered to the clamp seat 130. At the bottom, as the twisting roller 120 runs, the clamp seat 130 that is pressed downward can clamp and fix one end of the steel. When the twisting roller 120 cooperates with the clamp seat 130 to clamp and rotate one end of the steel, the hydraulic sub-rod of the second hydraulic component 160 in operation will drive the guide component 260 to laterally stretch the inclined steel. When the steel is twisted and gradually forms a spring structure, the stress relief pressing component 280 that is pressed by the reinforcing spring 290 and fits against the top of the spring can provide forced pressure to the initially formed steel. At this time, the steel that has been forcibly twisted can be forced to be pressurized on the outside of the twisting roller 120, and the stress inside the spring can be reduced with the preheated high temperature.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
