Description

Technical Field

[0001] The invention relates to the technical field of steel positioning, and in particular to a steel positioning and punching device for steel processing. Background Art

[0002] Steel is a material of a certain shape, size and performance made by pressure processing of steel ingots, steel billets or steel pipes. Most steel processing is done by pressure processing, which causes plastic deformation of the processed steel (billets, ingots, etc.).

[0003] In mechanical engineering and equipment manufacturing, steel pipes often need to be punched with precise threaded holes. If the pipe is thick and the punching time is long, it is necessary to spray coolant at the hole mouth to deal with the problem of heat accumulation. However, the outer wall of the pipe is curved, which makes it easy for the coolant to flow along the curved surface when sprayed to the hole mouth, resulting in the heat generated during the punching process cannot be taken away in time, affecting the processing accuracy of the threaded hole. Based on this, the present application proposes a steel positioning and punching device for steel processing. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a steel positioning and punching device for steel processing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A steel positioning and punching device for steel processing comprises a base plate, the upper end of the base plate is fixedly connected to a side plate, the outer wall of the side plate is U-shaped, a shell is installed on the lower end surface of the side plate, a drill bit is installed inside the shell, and one end of the drill bit extends to the outside of the shell, and adjustment grooves are provided on the outer walls on both sides of the shell, an adjustment rod is fixedly connected to the bottom of the adjustment groove, an adjustment block is slidably connected to the outer wall of the adjustment rod, connecting rods are fixedly connected to the outer walls on both sides of the adjustment block, an installation groove is provided at the lower end edge of the connecting rod, an elastic rope made of fluororubber material is clamped in the installation groove, and the lowest point of the elastic rope is lower than the horizontal height of the connecting rod and the drill bit end.

[0007] Preferably, a spring is sleeved on the outer wall of the adjusting rod, one end of the spring is fixedly connected to the top of the adjusting groove, and the other end of the spring is fixedly connected to the upper end surface of the adjusting block.

[0008] Preferably, the upper end of the base plate is fixedly connected to a support plate, a connecting block is slidably connected inside the support plate, and the outer walls on both sides of the connecting block are in close contact with the inner wall of the support plate, the side walls of the connecting block are fixedly connected to a fixing plate, the upper end surface of the support plate is fixedly connected to a hydraulic cylinder, and the telescopic end of the hydraulic cylinder is fixedly connected to the upper end surface of the connecting block.

[0009] Preferably, the outer wall of the fixed plate is circular, and a plurality of groups of slide grooves are arranged in an annular manner on the outer wall of the fixed plate. The bottoms of the plurality of slide grooves are fixedly connected with slide rods, and the slide rods are connected with adjustment frames through connecting blocks. The outer walls on both sides of the slide rods are in contact with the inner walls of the slide grooves.

[0010] Preferably, two groups of rubber pads made of silicone rubber material are installed at the corners of the upper end surface of the adjustment frame, and a through groove is provided between the two groups of rubber pads.

[0011] Preferably, a threaded rod is rotatably connected to the center of the fixed plate, and a limit block is fixedly provided at the end of the threaded rod, and the radius of the limit block is larger than the radius of the threaded rod.

[0012] Preferably, a slider is threadedly connected on the threaded section of the threaded rod, and the outer wall of the slider is rotatably connected to multiple groups of connecting plates.

[0013] Preferably, the outer wall of the fixing plate is fixedly connected to a limiting rod, and the sliding block is slidably connected to the outer wall of the limiting rod.

[0014] Preferably, a servo motor is fixedly connected to the center of the fixed plate, and the end of the servo motor output shaft is coaxially fixedly connected to the threaded rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention forms a stable flexible fixing belt on the outer wall of the pipe by arranging an elastic rope. After the coolant is sprayed to the hole, it is effectively gathered and retained in the punching area by the elastic rope, so as to prevent the coolant from losing along the outer wall of the arc-shaped pipe, so that the coolant can fully cover the hole, and timely take away the heat generated in the punching process, thereby preventing the occurrence of overheating problems, thereby maintaining the processing accuracy and quality of the threaded hole.

[0017] 2. The present invention drives multiple groups of adjustment frames to slide toward the edge or circle of the fixed plate through servo motors and threaded rods, so as to clamp and fix the pipe from the inside. The multiple groups of adjustment frames slide synchronously, and the clamping force on the pipe is evenly distributed around the pipe. This uniform clamping force can prevent deformation or damage of the pipe due to excessive force on a single point, ensure stability during the processing, and ensure that the force on the pipe during the clamping process is evenly distributed.

[0018] 3. The present invention arranges rubber pads on the outer walls of multiple groups of adjustment frames. During the fixing process, the rubber pads have good flexibility and elasticity, which reduces the risk of deformation or damage of the pipes during processing and ensures the structural integrity and processing accuracy of the pipes. In addition, the use of rubber pads also improves the stability of the entire processing process and avoids indentations or scratches on the surface of the pipes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] Embodiment 1:

[0028] Reference Figure 1-5, a steel positioning and punching device for steel processing, comprising a bottom plate 1, a side plate 2 is fixedly connected to the upper end of the bottom plate 1, the outer wall of the side plate 2 is U-shaped, a shell 8 is installed on the lower end surface of the side plate 2, a drill bit 9 is installed inside the shell 8, and one end thereof extends to the outside of the shell 8, and the outer walls on both sides of the shell 8 are provided with adjustment grooves 22, an adjustment rod 23 is fixedly connected to the bottom of the adjustment groove 22, an adjustment block 25 is slidably connected to the outer wall of the adjustment rod 23, and connecting rods 10 are fixedly connected to the outer walls of the adjustment block 25 on both sides of the adjustment block 25, and a mounting groove is opened at the lower end edge of the connecting rod 10, and an elastic rope 11 made of fluororubber material is clamped in the mounting groove, and the lowest point of the elastic rope 11 is lower than the horizontal height of the connecting rod 10 and the end of the drill bit 9, and a spring 24 is sleeved on the outer wall of the adjustment rod 23, one end of the spring 24 is fixedly connected to the top of the adjustment groove 22, and the other end of the spring 24 is fixedly connected to the upper end surface of the adjustment block 25;

[0029] Specifically: when punching a threaded hole into a steel pipe, the elastic rope 11 is pre-contacted with the outer wall of the pipe, and fits tightly to the surface of the pipe with its own elasticity. The elastic rope 11 is wrapped around the pipe with appropriate tension to form a flexible fixing belt, so that when the coolant is sprayed at the hole, the coolant can be retained in the elastic rope 11, which can effectively limit the loss of the coolant and make the coolant gather in the punching area to fully cover the hole. The spring 24 is arranged in conjunction with the elastic performance of the spring 24 itself, so that the elastic rope 11 can fit tightly to the outer wall of the pipe, thereby improving the tightness of the elastic rope 11 when in contact with the outer wall of the pipe, and further avoiding the loss of the coolant.

[0030] Embodiment 2:

[0031] Reference Figure 1 and Figure 6 , Figure 7 , the upper end of the bottom plate 1 is fixedly connected to a support plate 3, a connecting block 5 is slidably connected inside the support plate 3, and the outer walls on both sides of the connecting block 5 are in contact with the inner wall of the support plate 3, the side walls of the connecting block 5 are fixedly connected to a fixing plate 6, the upper end surface of the support plate 3 is fixedly connected to a hydraulic cylinder 4, the telescopic end of the hydraulic cylinder 4 is fixedly connected to the upper end surface of the connecting block 5, the outer wall of the fixing plate 6 is circular, and a plurality of groups of slide grooves 12 are arranged in an annular distribution on the outer wall of the fixing plate 6, the bottom of the plurality of groups of slide grooves 12 are fixedly connected to sliding rods 13, the sliding rods 13 are connected to an adjusting frame 14 through a connecting block 21, the outer walls on both sides of the sliding rods 13 are in contact with the inner wall of the slide groove 12, and two groups of rubber pads 15 made of silicone rubber material are installed at the corners of the upper end surface of the adjusting frame 14, and a through groove 16 is provided between the two groups of rubber pads 15;

[0032] Specifically, with the help of multiple groups of adjustment frames 14 extending outward or contracting inward to slide, the rubber pads 15 provided can clamp and fix the pipe from the inside of the steel, ensuring that the pipe remains stable during processing, while evenly applying clamping force to avoid local stress concentration and reduce the risk of pipe deformation or damage. The rubber pads 15 can be in close contact with the inner wall of the pipe after the adjustment frame 14 slides, thereby enhancing the clamping force. At the same time, the rubber pads 15 have certain flexibility and adaptability, and can adapt to the inner walls of pipes of different shapes and materials within a certain range.

[0033] A threaded rod 17 is rotatably connected at the center of the fixed plate 6, and a limit block 26 is fixedly provided at the end of the threaded rod 17. The radius of the limit block 26 is larger than the radius of the threaded rod 17. A slider 19 is threadedly connected to the threaded section of the threaded rod 17. The outer wall of the slider 19 is rotatably connected to multiple groups of connecting plates 20. The positions of the multiple groups of connecting plates 20 correspond to the positions of the multiple groups of adjustment frames 14 one by one. The other ends of the multiple groups of connecting plates 20 are rotatably connected to the adjacent adjustment frames 14 respectively. The outer wall of the fixed plate 6 is fixedly connected to the limit rod 18. The slider 19 is slidably connected to the outer wall of the limit rod 18. A servo motor 7 is fixedly connected at the center of the fixed plate 6. The end of the output shaft of the servo motor 7 is coaxially fixedly connected to the threaded rod 17.

[0034] Specifically, by means of the rotation of the threaded rod 17, the slider 19 is driven to slide horizontally, and the sliding movement drives the multiple groups of adjustment frames 14 to slide toward the edge or the center of the fixed plate 6, so that the clamping force on the pipe is evenly distributed around the pipe. This uniform clamping force can prevent the pipe from being deformed or damaged due to excessive force at a single point, thereby ensuring stability during the processing.

[0035] The functional principle of the present invention can be explained through the following operation mode: first, the steel pipe to be processed is sleeved on the outside of multiple groups of adjustment frames 14, and the hydraulic cylinder 4 is started so that its telescopic end pushes the connecting block 5 to slide up and down, and the height of the fixed plate 6 is further adjusted to better adapt to the outer diameter of the pipe. Then, the servo motor 7 is started to drive the threaded rod 17 to rotate, so that the slider 19 slides horizontally along the limit rod 18. According to the diameter of the pipe, by adjusting the position of the slider 19, the multiple groups of adjustment frames 14 are driven to slide synchronously toward the edge or center of the fixed plate 6. During the sliding process of the adjustment frame 14, the two groups of rubber pads 15 gradually approach the inner wall of the pipe, so that the rubber pads 15 are in close contact with the inner wall of the pipe to form a uniform clamping force, and the rubber pads 15 evenly apply clamping force during the fixing process to avoid local stress concentration and ensure that the pipe remains stable in the subsequent processing.

[0036] The hydraulic cylinder 4 drives the pipe to slide, and the elastic rope 11 is gradually close to the outer wall of the pipe until it is in contact with the outer wall of the pipe. At this time, the outer wall of the pipe does not contact the ends of the connecting rod 10 and the drill bit 9. The elastic performance of the spring 24 can make the elastic rope 11 fit tightly to the outer wall of the pipe, ensuring that the elastic rope 11 surrounds the pipe to form a stable flexible fixing belt, providing protection for the subsequent injection of coolant, and then the drill bit 9 is used to punch the threaded hole. After the drill bit 9 starts drilling, the coolant is sprayed to the hole mouth through the external cooling device. The elastic rope 11 can effectively gather the coolant in the drilling area to prevent the coolant from flowing along the outer wall of the arc-shaped pipe, fully cover the hole mouth and promptly take away the heat generated during the drilling process.

[0037] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
