Description

Technical Field

[0001] This invention relates to the field of metal pressure processing equipment technology, and more specifically to a forming equipment for the production of stainless steel pipes. Background Technology

[0002] Stamping and forming equipment for stainless steel pipe production is widely used in the pipe processing field, greatly improving the forming efficiency and consistency of steel pipes, and playing an important role in realizing large-scale and automated production.

[0003] The main structure of stamping forming equipment for stainless steel pipe production typically includes a mechanical body consisting of a bed, slide block, guide rail, and mold mounting base, achieving high-rigidity stamping motion; the drive system uses hydraulic or servo motors to provide power; the control system is responsible for setting operating parameters and monitoring the process; the upper and lower mold groups can be replaced with special tools such as punching dies, bending dies, or necking dies according to process requirements. All parts work together to complete processing tasks such as punching, bending, and end forming of steel pipes, featuring high load capacity, high stability, and repetitive operation. However, the above working method still has the following shortcomings: 1. Low production efficiency is the primary bottleneck of traditional equipment. Existing stamping equipment usually requires multiple clamping and positioning operations. 1. Manual handling not only requires a lot of time and manpower, but also easily causes unnecessary deformation during the stamping process, affecting the quality of the final product; 2. Unstable finished product quality is another prominent problem. During the stamping process, the steel pipe is prone to local collapse and deformation, especially when symmetrically punching. The pipe lacks effective internal support, resulting in insufficient hole accuracy and pipe deformation. The fine waste material from the steel pipe wall generated after punching is easy to accumulate on the punching device, which also affects the punching efficiency; 3. In order to improve production efficiency, the equipment needs to be able to achieve continuous stamping. However, in order to ensure the flexibility of the equipment, frequent adjustments and changes of molds are required. Existing equipment is difficult to achieve a balance between rapid switching and efficient production. Summary of the Invention

[0011] Furthermore, a side plate is provided on the right side of the stabilizing mechanism, and the right side of the side plate is fixedly connected to the left side of the synchronizing screw. Four support springs are provided inside the side plate, and a central disk is fixedly connected to the left side of the side plate.

[0014] The technical effects and advantages of this invention are as follows: This invention features two sets of clamps to ensure clamping stability. The distance between the two sets of clamps is adjusted by a length-adjusting screw to accommodate stainless steel pipes of different lengths. Simultaneously, the feeding motors at the bottom of the two sets of clamps on the right drive them to move along the feeding guide rail, thereby moving the clamped steel pipe so that the inner support mechanism can extend into the interior of the stainless steel pipe for subsequent synchronous support operations. The rollers on the clamps can rotate the stainless steel pipe as needed to meet different processing requirements, thereby improving equipment efficiency and reducing the number of clamping and positioning operations.

[0015] This invention features an internal support mechanism at the center of the device. This internal support mechanism moves synchronously with the stamping part inside the stainless steel pipe. The active ring is driven to rotate by a support motor, which in turn pushes the inclined block to press the support tile against the inner wall of the stainless steel pipe. This provides support to the inner wall of the stainless steel pipe during processing. At the same time, the action of multiple rubber blocks ensures that the pipe adapts to the inner wall without damaging it, thus helping to prevent deformation of the stainless steel pipe due to uneven stress during processing.

[0016] This invention improves production efficiency by providing a turntable below the electric push rod and rotating the punch on the turntable to the processing position under the drive of the conversion motor. The equipment can achieve continuous stamping without frequent adjustment and mold replacement, thus achieving a balance between rapid switching and high-efficiency production.

A length adjusting screw 123 is provided on the right end face of the transverse screw 123. A synchronous belt box 125 is provided. A synchronous screw 1251 is provided on the left side of the synchronous belt box 125. First limit rods 1252 are provided on both sides of the synchronous screw 1251.

[0032] The synchronous belt box 125 drives the inner support mechanism 2 to move simultaneously with the movement of the stamping part 5, ensuring that the two are highly synchronized and preventing the stainless steel pipe from deforming and being damaged during processing due to inadequate support.

[0033] Reference Figure 2 and Figure 12 A feeding motor 1121 is provided in the middle of the feeding base 112. First screw fixing seats 1122 are provided on both sides of the feeding base 112.

A length adjusting motor 141 is provided on the side of the length adjusting base 14. The top and left side of the length adjusting base 14... The bottom of the second base 13 is fixedly connected, and a bidirectional screw 132 is provided in the middle of the second base 13. A first transverse base 134 is provided on both sides of the bidirectional screw 132. Two second guide blocks 133 are provided on the inner bottom surface of the second base 13. The bottom surface of the first transverse base 134 is fixedly connected to the bottom surface of the clamping base plate 41. A transverse motor 1211 is provided on the left side of the stamping base 121. A second motor 131 is fixedly connected to the front side of the second base 13. There are two second bases 13 and four clamps 4.

[0034] Driven by the length adjustment motor 141, the distance between the two sets of clamps 4 can be shortened, thus ensuring that the device can adapt to shorter stainless steel pipes. At the same time, increasing the distance between the two sets of clamps 4 can adapt to longer stainless steel pipes. The second motor 131 drives the bidirectional screw 132 to rotate, causing the two first transverse bases 134 to bring the clamps 4 on their tops closer together, thereby clamping the stainless steel pipe. Then, the feeding motor 1121 drives the feeding base 112 to move to the right, sending the fixed stainless steel pipe into the processing position.

[0035] Reference Figure 11 A linkage plate 15 is fixedly connected to the front side of the stamping frame 124. A push arm 152 is movably connected to the bottom of the linkage plate 15. A second spring 151 is provided on the upper part of the push arm 152. A conveyor belt 16 is provided at the bottom of the device base plate 11. A roller seat 162 is provided on the rear side of the conveyor belt 16. A helical rack 161 is provided at the four corners of the conveyor belt 16. The top of the helical rack 161 is fixedly connected to the bottom of the device base plate 11.

[0036] The stamping frame 124 drives the push arm 152 at the bottom of the linkage plate 15 to move, so that the push arm 152 continuously pushes the inclined rack 161 on the conveyor belt 16 while adjusting left and right, thereby realizing the conveying of metal waste generated during the processing, preventing metal waste from accumulating in the device, and ensuring stable operation of the equipment.

[0037] Reference Figure 3 , Figure 4 and Figure 5 The inner support mechanism 2 has an inner support body 21 in the middle. The front side of the inner support body 21 is fixedly connected to a first base 24. The rear side of the inner support body 21 is provided with a first guide block 25. The two sides of the inner support body 21 are provided with active rings 23. The upper and lower sides of the inner support body 21 are provided with support tiles 22. The top and bottom of the inner support body 21 are each fixedly connected with two return springs 211. The middle of the return springs 211 is provided with a limit barrel 212. The right side of the first base 24 is fixedly connected to a support motor 241. The two sides of the support motor 241 are provided with drive gears 2411.

The outer side of the support tile 22 is provided with twenty-five rubber blocks 223.

[0038] The drive gears 2411 on both sides of the support motor 241 drive the active ring 23 to rotate. The active ring 23 pushes the two rollers 222 on the support tile 22, causing the support tiles 22 on the upper and lower sides of the inner support body 21 to move away from the axis. The return spring 211 is in a stretched state so that the support tile 22 can return to its original position in the subsequent action. The linear movement of the support tile 22 is ensured by the action of the first guide block 25 and the limiting barrel 212.

[0039] Reference Figure 6 Two secondary guide columns 224 are fixedly connected to the left side of the support tile 22, and two main guide columns 2211 are fixedly connected to the bottom of the support base 221. A first spring 2231 is provided at the bottom of the rubber block 223. Through the cooperation of the main guide column 2211 and the limiting barrel 212, as well as the cooperation of the secondary guide column 224 and the first guide block 25, the stability of the support process is ensured and the deviation is prevented. The spring 2231 enables each rubber block 223 to better fit the inner wall of the stainless steel pipe.

[0040] Reference Figure 7 Two fixed rods 233 are fixedly connected to the middle of the active ring 23. A toothed ring 232 is provided on the inner side of the active ring 23. Two inclined blocks 231 are fixedly connected to the outer side of the active ring 23. By replacing different inclined blocks 231, the movement stroke of the support tile 22 can be adjusted, thereby adapting to stainless steel pipes of different diameters.

[0041] Reference Figure 8 A side plate 31 is provided on the right side of the stabilizing mechanism 3. The right side of the side plate 31 is fixedly connected to the left side of the synchronous screw 1251. Four support springs 32 are provided inside the side plate 31. A central disk 33 is fixedly connected to the left side of the side plate 31. Four swing arms 34 are provided on the side of the central disk 33. Guide wheels 35 are provided at the ends of the swing arms 34. The stabilizing mechanism 3 supports the synchronous screw 1251, preventing the synchronous screw 1251 from bending excessively due to the weight of the internal support mechanism 2, and ensuring the normal operation of the equipment.

[0042] Reference Figure 9 A flipping motor 42 is provided above the clamping base plate 41. A transmission belt 43 is provided on the right side of the flipping motor 42. Two rollers 44 are provided on the right side of the transmission belt 43. Rubber strips 441 are provided on the sides of the rollers 44. The flipping motor 42 drives the two rollers 44, so that the stainless steel pipe can be rotated as needed, thereby completing multi-angle processing.

[0043] Reference Figure 10 An electric push rod 52 is provided in the middle of the support frame 51. A fixing plate 53 is fixedly connected to the bottom of the electric push rod 52. A conversion motor 54 is provided on the left side of the fixing plate 53. A turntable 55 is provided below the conversion motor 54. Four punches 56 are provided at the bottom of the turntable 55.

[0044] The working principle of this invention is as follows: During the feeding stage, based on the required length of the stainless steel pipe to be processed, the length adjusting motor 141 drives the length adjusting base 14 to move laterally along the second base 13, adjusting the distance between the two second bases 13. Subsequently, the second motor 131 drives the bidirectional screw 132 to rotate, causing the first transverse bases 134 on both sides to move towards the center. The first transverse bases 134 then drive the upper clamps 4 to move closer together, and the rubber strips 441 on the roller 44 contact the surface of the stainless steel pipe, thus fixing the stainless steel pipe. Then, driven by the feeding motor 1121 at the bottom of the second base 13 on the right, the feeding base 112 moves along the feeding guide rail 111, causing the stainless steel pipe to move to the right and the stabilizing mechanism 3 to penetrate into the stainless steel pipe. Under the action of the four support springs 32, the guide wheel 35 at the end of the swing arm 34 is pressed tightly against the inner wall of the stainless steel pipe. Through the support of the stabilizing mechanism 3, the synchronous screw 1251 and the first limit rod 1252 are prevented from bending excessively due to gravity, so that the inner support mechanism 2 can be moved to the corresponding position as needed.

[0045] During the processing stage, after the stainless steel pipe moves to the processing position under the drive of the right clamp 4, the stamping frame 124 drives the support frame 51 on top to move along the transverse screw 123 under the drive of the transverse motor 1211. According to the processing needs, the stamping part 5 is moved to the preset position. The punch 56 required for processing is rotated to the processing position by the conversion motor 54 on the side of the electric push rod 52. The electric push rod 52 pushes the fixed plate 53 and the turntable 55 to move downward, so that the punch 56 performs the required processing operation on the surface of the stainless steel pipe. After processing, the electric push rod 52 returns it to its original position for flipping or replacing the punch 56. The metal waste generated during processing falls onto the conveyor belt 16 at the bottom of the device. The stamping frame 124 drives the push arm 152 at the bottom of the linkage plate 15 to move, so that the push arm 152 continuously pushes the inclined rack 161 on the conveyor belt 16 while adjusting left and right, thereby realizing the conveying of the metal waste generated during processing, preventing the metal waste from accumulating in the device and ensuring the stable operation of the equipment.

[0046] During the synchronous support stage, while the transverse motor 1211 drives the transverse screw 123 to rotate, the synchronous screw 1251 rotates synchronously through the transmission action of the synchronous belt box 125, thereby driving the inner support mechanism 2 to move synchronously along the synchronous screw 1251. Under the action of the synchronous belt box 125, the inner support mechanism 2 and the stamping part 5 move synchronously, so that the inner support mechanism 2 is always below the processing position in the stamping part 5. When the inner support mechanism 2 moves to the processing position, the support motor 241 drives the active rings 23 on both sides to rotate. Through the contact between the inclined surface at the end of the inclined block 231 and the roller 222 at the bottom of the support tile 22, the support tiles 22 on the upper and lower sides of the inner support mechanism 2 are pushed to move away from the axis. The rubber blocks 223 set on the support tile 22 are attached to the inner wall of the stainless steel pipe. Under the support of the support tiles 22 on both sides, the stainless steel pipe will not deform due to uneven force during the processing.

[0047] During the flipping stage, the flipping motor 42 drives the upper and lower rollers 44 to rotate, thereby causing the stainless steel pipe to rotate to the next processing position as required, and then perform the same processing operation.

[0048] After processing, the second base 13 on the right side drives the clamp 4 on its upper part to remove the stainless steel pipe, thus completing the processing operation.
