[0018] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 2As shown, the cold-rolled steel processing equipment of the present invention is used for processing tubular workpieces. In this embodiment, the workpiece used for processing is a cold-rolled steel pipe, which includes an equipment body 1, which includes a machine table 2, a hydraulic mechanism 3 installed on the machine table 2, and a power source 4 arranged above the hydraulic mechanism 3. The power source 4 is preferably a motor with stable power output and easy control. The power source 4 is equipped with a protective shell made of metal, and the metal is selected to be steel or aluminum alloy. The outer surface of the protective shell is coated with an anti-rust coating. The output shaft of the power source 4 passes through the mounting plate 41 and is fixedly connected to the upper end of the hydraulic mechanism 3 to drive the hydraulic mechanism 3 to rise and fall to realize stamping work. Two slotting components 6 are symmetrically provided, and the two slotting components 6 are respectively arranged on the left and right sides of the hydraulic mechanism 3. During the stamping process, they are used to slot and punch holes on both sides of the cold-rolled steel pipe to realize integrated operation, simplify the processing flow, and improve the processing efficiency.

[0020] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, the hydraulic mechanism 3 includes a bottom plate 31, a pressing plate 32 and a forming die 5. The forming die 5 is mounted on the upper end surface of the bottom plate 31 and is located directly below the pressing plate 32. The bottom plate 31 is mounted on the upper end surface of the machine table 2 for mounting the forming die 5. The pressing plate 32 is provided with three pressing blocks in parallel on one side facing the forming die 5, which are a second pressing block 9 located on both sides, a third pressing block 10, and a first pressing block 8 located in the middle. The lower part of one end of the first pressing block 8 is an arc surface, which is used to punch out a slope structure for the stamping part when in use. The forming die 5 is composed of The two groups of symmetrically arranged limit modules 51 are composed of two vertical and spaced templates 511, and a plurality of rubber columns 512 arranged between the two templates 511. The rubber columns 512 are used to buffer and reduce shock for the limit modules 51. The two groups of limit modules 51 are arranged in parallel and spaced. The space between the two groups of limit modules 51 forms a mold cavity. The opening of the mold cavity for the cold-rolled steel pipe to extend into is the feed port 52. At the tail end of the forming mold 5, that is, the end facing away from the feed port 52, a bearing Component 7, the bearing component 7 is installed on the bottom plate 31, and the bearing component 7 is composed of an upper clamping block, a lower clamping block and a bearing rod 71. A clamping cavity is provided between the upper clamping block and the lower clamping block, and the clamping cavity is composed of grooves arranged in the upper clamping block and the lower clamping block facing each other. One end of the bearing rod 71 extends into the clamping cavity, and the upper clamping block and the lower clamping block fix the bearing rod 71 inside the clamping cavity by fastening bolts. The part of the bearing rod 71 extending out of the clamping cavity extends into the mold cavity and extends to the feed port 52. In the process of the cold-rolled steel pipe extending into the mold cavity from the feed port 52, the bearing rod 7 1 also extends into the lumen of the cold-rolled steel pipe. The bearing rod 71 is rectangular. The width and height of the bearing rod 71 are both smaller than the inner diameter of the lumen. After insertion, there is a gap between the bearing rod 71 and the inner wall of the lumen. When the cold-rolled steel pipe is inserted into the die cavity, its bottom surface contacts the upper end surface of the bottom plate 31, which plays a supporting role during stamping. The bearing rod 71 plays a supporting and limiting role in the cold-rolled steel pipe, which is convenient for shaping the stamping part. A limit block can also be set on the bearing rod 71 according to the usage, and the limit block is used to limit the length of the bearing rod 71 inserted into the cold-rolled steel pipe.

[0021] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a part of the slotting assembly 6 is arranged on the bottom plate 31 on one side of the forming mold 5, and the other part is arranged on the machine table 2. The part arranged on the bottom plate 31 includes a base 65 and a slotting knife 61 slidably connected to the base 65, and the part arranged on the machine table 2 is a traction member; wherein a slide rail is provided on the base 65, and the slotting knife 61 is composed of a knife seat, a punching knife and a drill bit. The knife seat is placed in the slide rail for sliding connection. The punching knife and the drill bit are both arranged on the side of the knife seat facing the forming mold 5, and the drill bit is located below the punching knife. A stopper 62 is provided at one end of the base 65 away from the forming mold 5, and a traction groove communicating with the slide rail is provided below the stopper 62. The side of the traction groove facing the outside has an opening, and a traction plate is provided at the bottom of the side of the knife seat away from the punching knife. The traction plate is placed in the slide rail and can extend into the traction groove; the traction member is composed of a fixed rod 63 fixed on the machine table 2, a connecting rod threadedly connected to the traction plate, and a spring 64 connected between the fixed rod 63 and the connecting rod. The function of the traction member is to pull the completed stamping operation The slotting knife 61 is reset by the tensile force of the spring 64; when in use, a through slot is opened on the limit module 51, and the through slot can accommodate the extension of the base 65 and the knife seat. The two slotting components 6 move synchronously under the drive of the second pressing block 9 and the third pressing block 10. The contact surface between the knife seat and the second pressing block 9 and the third pressing block 10 is an arc surface, which is convenient for the second pressing block 9 and the third pressing block 10 to press down without obvious obstruction. The height of the first pressing block 8 is less than that of the second pressing block 9 and the third pressing block 10, and the punching knife is at least A deep groove is pressed out on the side of the cold-rolled steel pipe, and the length of the deep groove corresponds to the length of the stamping part. The drill bit punches a hole on the cold-rolled steel pipe below the deep groove. During stamping, the stamping knives on both sides simultaneously press against the left and right sides of the cold-rolled steel pipe. With the pressure applied by the second pressing block 9 and the third pressing block 10, the two stamping knives move toward each other until the deep groove is opened. At this time, the drill bit also synchronously passes through the side wall of the cold-rolled steel pipe and extends into the tube cavity. The stamping knife and the drill bit can support the first pressing block 8 in stamping the cold-rolled steel pipe. like Figure 1-Figure 5As shown, the support assembly arranged on the machine 2 is used to install the power source 4, which includes a plurality of support rods 42 and a mounting plate 41 arranged on the support rods 42. The support rods 42 are respectively arranged at the four corners of the machine 2. The power source 4 is fixed to the upper end surface of the mounting plate 41. The output shaft of the power source 4 passes downward through the mounting plate 41 and is connected to the upper end surface of the pressing plate 32 through a flange, so as to drive the pressing plate 32 to move up and down along the guide assembly. The guide assembly is composed of a plurality of optical axes and a shaft sleeve arranged on the lower end surface of the pressing plate 32. An axial hole communicating with the shaft sleeve is opened on the pressing plate 32. The shaft sleeve corresponds to the optical axis one by one. The shaft sleeve is arranged on the optical axis. The top of the optical axis passes through the shaft sleeve and the shaft hole respectively and passes through the upper end surface of the pressing plate 32. When the pressing plate 32 moves, the shaft sleeve arranged on the pressing plate 3 is synchronously driven 2, the three pressing blocks on the lower end face move, wherein the first pressing block 8 is located just above the die cavity and is used to stamp the upper end face of the cold-rolled steel pipe extending into the die cavity, the second pressing block 9 and the third pressing block 10 are respectively on the left and right sides of the first pressing block 8, and are respectively inserted between the stopper 62 and the knife holder of the two slotting assemblies 6 when moving downward, because the stopper 62 is fixedly arranged on the base 65, and the interval between the initial position of the knife holder on the slide rail and the stopper 62 is smaller than the width of the second pressing block 9 and the third pressing block 10, the second pressing block 9 and the third pressing block 10 are squeezed into the interval through the large width, thereby squeezing the knife holder, and then realizing the movement of the driving knife holder, and the two photoelectric sensors arranged on the hanger are used to detect the lifting height of the pressing plate 32 to improve the accuracy of stamping.

[0022] like Figure 1-Figure 6 As shown, the cold-rolled steel processing technology of the present invention is realized based on the cold-rolled steel processing equipment, and the process includes the following steps: Step 1, raw material cutting, dividing the raw material into a number of cold-rolled steel pipes of equal length, and stacking them beside the equipment for standby; Step 2: Adjustment before stamping: manually extend one end of a single cold-rolled steel tube into the die cavity, and extend the bearing rod 71 into the tube cavity of the cold-rolled steel tube. The diameter of the bearing rod 71 is smaller than the inner diameter of the tube cavity, so that the stamping part can be pressed out for the upper end of the cold-rolled steel tube during stamping. After the cold-rolled steel tube is sleeved on the bearing rod 71, the four sides of the bearing rod 71 are not in contact with the inner wall of the tube cavity, and the bottom of the cold-rolled steel tube is placed on the bottom surface of the die cavity; Step 3: Steel pipe stamping. After the cold-rolled steel pipe is adjusted into place, the power source 4 is started to drive the pressing plate 32 to move downward along the optical axis. The three pressing blocks arranged on the lower end surface of the pressing plate 32 move downward synchronously. At this time, the first pressing block 8 extends into the mold cavity and presses on the upper end surface of the cold-rolled steel pipe. The second pressing block 9 is inserted between the stopper 62 and the knife seat of the left slotting component 6. The initial interval between the stopper 62 and the knife seat is not enough to accommodate the second pressing block 9. Therefore, when the second pressing block 9 is inserted, the knife seat is driven to move along the slide rail toward the mold cavity. The third pressing block 10 drives the slotting component 6 on the right in the same way to achieve the same action. When the three pressing blocks move When in place, the first pressing block 8 presses down to make the part of the cold-rolled steel pipe extending into the die cavity, and a stamping part with a length of 5-15cm, preferably 13cm, and a sinking depth of 1.5cm is pressed out on the top of the whole. On the cold-rolled steel pipe below the stamping part, a deep groove is pressed out on both sides by the stamping knife. The length of the deep groove is the same as that of the stamping part, and the depth of the deep groove is 0.5-2.5cm. The drill bit moving synchronously with the stamping knife punches a through punching hole on the side wall of the cold-rolled steel pipe. After stamping, the part where the stamping part transitions to the cold-rolled steel pipe is a curved surface, and the curvature of the curved surface is 5-20°, preferably 10°; Step 4: stamping detection. When the pressing plate 32 moves downward in step 3, two photoelectric sensors arranged on the rack detect the height of the pressing plate 32 when it is lifted or lowered, so as to adjust the moving distance of the pressing plate 32 during stamping and set the parameters of the stamping depth of the stamping part. Step 5: Reset the punching. After the punching is completed, the power source 4 drives the pressing plate 32 to rise upward, the first pressing block 8 is separated from the die cavity, and the second pressing block 9 and the third pressing block 10 are synchronously separated from the slot assembly 6. The movement of the knife seat during punching stretches the spring 64. After the punching is completed, the knife seat that loses the driving force moves toward the stopper 62 under the action of the spring 64 until the traction plate is inserted into the traction slot, and the knife seat reset is completed. Step 6: Finished product inspection: pull the cold-rolled steel pipe out of the die cavity, check the stamping part, deep groove and punching hole, and place it in the storage area after it passes the inspection. Repeat the above steps to achieve uninterrupted processing of the cold-rolled steel pipe.

[0023] By setting up a hydraulic mechanism 3 and a slotting component 6 that can be linked, and using the same power source 4 to drive, the effects of stamping, slotting and punching can be achieved in one processing process, which greatly simplifies the processing process, reduces cost investment, and improves processing efficiency. Combined with the processing technology, the cold-rolled steel pipe can be quickly produced and processed to achieve a technical effect of short process and high efficiency; at the same time, the protective measures of the load-bearing rod 71 and the photoelectric sensor are set to increase the processing accuracy, prevent the stroke of the pressure block from being too large during stamping, and improve the yield rate.

[0024] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

The cold-rolled steel material processing equipment according to claim 7, characterized in that: An "L"-shaped bracket is also provided on the mounting plate (41), and at least two photoelectric sensors are provided on the bracket. The two photoelectric sensors are arranged with a spacing up and down, and the detection heads of the photoelectric sensors face the hydraulic mechanism (3). The photoelectric sensors are used to detect the lifting height of the pressure plate (32).

10. A cold rolled steel material processing process, based on the cold rolled steel material processing equipment according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Cut the raw materials into several cold-rolled steel pipes of equal length and stack them beside the equipment for standby use; Step 2: Adjustment before stamping: manually insert one end of a single cold-rolled steel tube into the die cavity, and insert the bearing rod (71) into the tube cavity of the cold-rolled steel tube. The diameter of the bearing rod (71) is smaller than the inner diameter of the tube cavity, so that a stamping portion can be pressed out for the upper end of the cold-rolled steel tube during stamping. After the cold-rolled steel tube is sleeved on the bearing rod (71), the four sides of the bearing rod (71) are not in contact with the inner wall of the tube cavity, and the bottom of the cold-rolled steel tube is placed on the bottom surface of the die cavity. Step 3: Steel pipe stamping. After the cold-rolled steel pipe is adjusted into place, the power source (4) is started to drive the pressing plate (32) to move downward along the optical axis. The three pressing blocks arranged on the lower end surface of the pressing plate (32) move downward synchronously. At this time, the first pressing block (8) extends into the mold cavity and presses on the upper end surface of the cold-rolled steel pipe. The second pressing block (9) is inserted between the stopper (62) and the knife seat of the left slotting assembly (6). The initial spacing between the stopper (62) and the knife seat is not enough to accommodate the second pressing block (9). Therefore, when the second pressing block (9) is inserted, the knife seat is driven to move along the slide rail toward the mold cavity. The third pressing block (10) drives the slotting on the right in the same way. Component (6) realizes the same action. When the three pressing blocks move into place, the first pressing block (8) presses down to make the part of the cold-rolled steel pipe extending into the die cavity, and a stamping part with a length of 5-15 cm and a depth of 1-5 cm is pressed out on the top of the whole. On the cold-rolled steel pipe below the stamping part, a deep groove is pressed out on both sides by the stamping knife. The length of the deep groove is the same as that of the stamping part, and the depth of the deep groove is 0.5-2.5 cm. The drill bit moving synchronously with the stamping knife punches a through punch hole on the side wall of the cold-rolled steel pipe. After stamping, the part where the stamping part transitions to the cold-rolled steel pipe is an arc surface, and the curvature of the arc surface is 5-20°. Step 4: stamping detection. When the pressing plate (32) moves downward in step 3, two photoelectric sensors arranged on the bracket detect the height of the pressing plate (32) when it is lifted or lowered, so as to adjust the moving distance of the pressing plate (32) during stamping and set the parameters of the stamping depth of the stamping part. Step 5, stamping reset. After the stamping is completed, the power source (4) drives the pressing plate (32) to rise upward, the first pressing block (8) is separated from the die cavity, and the second pressing block (9) and the third pressing block (10) are synchronously separated from the slot assembly (6). The movement of the knife seat during stamping causes the spring (64) to be stretched. After the stamping is completed, the knife seat that loses the driving force moves toward the stop block (62) under the action of the spring (64) until the traction plate is inserted into the traction slot, and the knife seat reset is completed; Step 6: Finished product inspection: pull the cold-rolled steel pipe out of the die cavity, check the stamping part, deep groove and punching hole, and place it in the storage area after it passes the inspection. Repeat the above steps to achieve uninterrupted processing of the cold-rolled steel pipe.
