Description

Technical Field

[0001] The invention relates to the technical field of thread processing, in particular to an electric round steel threading machine with an easy-to-clean die. Background Art

[0002] Thread machining is a process that uses tools for making threads, such as cutting, turning, milling, and grinding, to process workpieces. It generally refers to the method of machining threads on workpieces using forming tools or grinding tools, mainly including turning, milling, tapping, threading, grinding, grinding, and whirlwind cutting. When turning, milling, and grinding threads, the machine tool's transmission chain ensures that the turning tool, milling cutter, or grinding wheel moves one lead accurately and evenly along the axial direction of the workpiece for each rotation of the workpiece. When tapping or threading, the tool (tap or die) and the workpiece rotate relative to each other, and the first-formed thread groove guides the tool (or workpiece) to move axially.

[0003] An electric round steel threading machine with easy-to-clean die, with announcement number CN 217253429 U, includes a main body and a movable shaft symmetrically fixed to one side of the main body, a die mechanism is slidably arranged on the movable shaft, and the die mechanism includes a die curved plate frame, a die head, a die sleeve, handle one and handle two. In this application, a slider is fixedly arranged on the upper and lower left and right surfaces of the regular octagonal die head to match the die groove in the die sleeve. The design of the slider and the slide groove facilitates the installation and replacement of the die head, thereby facilitating the cleaning of the die head and the die sleeve. In this application, the die head as a whole is evenly divided into four parts, which are connected and fixed by bolts and can also be separated, so that the inner wall of the processed circular mouth of the die head is further cleaned, so that the die is easier to clean and the cleaning effect is better.

[0004] During use, the following problems still exist:

[0005] The die used cannot be adjusted to different sizes of round steel pipes. Different dies need to be replaced each time they are used.

The circular ring is inclined to open a material guide groove between the die. Blocks are fixed on both sides of the material guide groove. The use of the blocks facilitates the setting of the blades and support springs. Blades are rotatably connected to the blocks. The ends of the blades are close to each other. The inclination line of the blades deviates from the center of the disc. A support spring is connected between one side of the blade and the block.

[0012] As a preferred solution of the electric round steel threading machine with easy-to-clean die of the present invention, a support assembly for supporting the round steel pipe is vertically fixed to one end of the middle part of the slide away from the material guide assembly.

[0013] As a preferred solution of the electric round steel threading machine with easy-to-clean die of the present invention, the support assembly includes a support rod fixed in the middle of the slide, and the support rod can be a telescopic rod to facilitate height adjustment. A connecting plate is provided on one side of the top of the support rod, and elastically contractible springs on both sides are fixed to the end of the connecting plate. Extrusion springs are connected between the two sides of the spring sheet and the two sides of the middle of the connecting plate. By using the extrusion springs, the two sides of the spring sheet can be kept in an elastically raised state at all times.

[0014] As a preferred solution of the electric round steel threading machine with easy-to-clean die of the present invention, a turntable that can move up and down is connected between one side of the top of the support rod and the connecting plate, and the turntable can also be rotated electrically, which can be selected according to the actual situation.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example, see Figure 1 , Figure 2 and Figure 3 This embodiment provides an electric round steel threading machine with easy-to-clean die, including a mounting plate 100, which is similar to a workbench on a machine tool. The present application is made of steel. A sleeve 200 is fixed to the top of one side of the mounting plate 100. The sleeve 200 is used to place a chuck 300 and a fastening disk 400. The chuck 300 is rotatably connected to one side of the sleeve 200, and the fastening disk 400 is rotatably connected to the other side of the sleeve 200. The chuck 300 and the fastening disk 400 are rotatably connected to the sleeve 200 together. The round steel pipe can be clamped by using the chuck 300 and the fastening plate 400. Both the chuck 300 and the fastening plate 400 are electric chucks. The chuck 300 and the fastening plate 400 can rotate inside the sleeve 200. This can be achieved by the engagement of a motor and a gear rack. The rack is installed on the chuck 300 and the fastening plate 400, and the gear is installed at the output end of the motor. The gear rack is engaged with each other. The electric chuck can drive the main shaft to rotate through the motor, and the chuck rotates in unison. This belongs to the prior art. Detailed description is omitted. Two slide rails 500 are laterally distributed on the top of the other side of the mounting plate 100. The two slide rails 500 are respectively distributed at the front and rear positions of the top of the other side of the mounting plate 100. A slide plate 600 is slidably connected to the slide rail 500. The slide plate 600 has a limit pin and the like, and can be installed according to specific actual conditions. A holder 700 is vertically fixed at both ends of the slide plate 600. The holder 700 can be used to select a structure for fixing a disc 800 according to specific usage conditions. The present application adopts a combination of a fastening pin and a fastening spring for fastening, which belongs to the prior art and is omitted here. A disc 800 is clamped on the holder 700. Clamping plates are fixed at both ends of the disc 800 at the position of the holder 700. Adjustable die dies 900 are evenly clamped on the disc 800. By adjusting the size of the die dies 900, thread processing of round steel pipes of different sizes can be facilitated. A guide component 1010 for guiding debris out is fixed at one end of the disc 800 close to the fastening plate 400.

[0033] When in use, the size of the die 900 is adjusted to adapt to round steel pipes of different sizes. The steel pipe passes through the chuck 300 and the fastening disk 400 and then enters the disc 800, and contacts the die 900. The round steel pipe is then fastened by the chuck 300 and the fastening disk 400. The rotation of the chuck 300 and the fastening disk 400 drives the round steel pipe to rotate on the die 900 to achieve the purpose of thread processing. By moving the position of the slide plate 600 on the slide rail 500, it is beneficial to move the die 900 on the position of the round steel pipe, and it is convenient to process it to the appropriate position. The threaded debris is exported from the guide assembly 1010 to the die 900 to facilitate cleaning at the die 900.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The die 900 includes a fixing plate 901 evenly distributed on the disc 800. The fixing plate 901 can be increased with scale lines according to the specific distance. The fixing plate 901 can be better installed through the scale lines. The intersection of the extension line of the end of the fixing plate 901 coincides with the center of the disc 800, so that the end of the fixing plate 901 is at the same center of the circle to prevent the end of the fixing plate 901 from being at the same center of the circle, causing a part of the thread to fail to be processed or be shallow, affecting normal use. The end of the fixing plate 901 is provided with an arc groove 902. The use of the arc groove 902 facilitates the installation of the tooth body 903. The arc groove A thread body 903 is slidably connected to the groove 902. The thread body 903 is used to facilitate normal thread processing. The material used for the thread body 903 has a certain elasticity to prevent the lack of elasticity from causing the normal size adjustment. An installation groove 906 is opened in the middle of one side near the end of the fixing plate 901. The installation groove 906 is used for the installation of a telescopic part 907. The installation groove 906 has a telescopic part 907 connected to the top of the middle part of the thread body 903. The telescopic part 907 uses a hydraulic cylinder or an additional air cylinder, which is selected specifically according to the elasticity of the thread body 903.

[0035] When in use, the telescopic member 907 can be extended or retracted according to the diameter of the specific round steel pipe. The extension and retraction of the telescopic member 907 squeezes the tooth body 903 in the arc groove 902, so that the curvature at the tooth body 903 becomes larger, thereby adapting to round steel pipes of different sizes. At the same time, it is necessary to adjust the position of the fixed plate 901 on the disc 800 to facilitate the adaptation of the teeth 903 to the same center position due to the increased curvature. When it is necessary to adjust the size, the telescopic member 907 is retracted. The retraction of the telescopic member 907 pulls up the tooth body 903 in the arc groove 902, so that the curvature at the tooth body 903 becomes smaller, thereby adapting to round steel pipes of different sizes. At the same time, it is necessary to adjust the position of the fixed plate 901 on the disc 800 to facilitate the adaptation of the teeth 903 to the same center position due to the reduced curvature.

[0036] Reference Figure 1 , Figure 2and Figure 4 The die 900 also includes a limiting groove 904 opened in the middle of the die body 903, and a limiting rod 905 is distributed in the limiting groove 904. The distribution of the limiting rod 905 should not be too crowded, that is, the number does not need to be too large to prevent the arc from being restricted too much and causing the effect of extrusion deformation. The limiting rod 905 is fixedly connected to the end of the fixed plate 901 to limit the change of the arc.

[0037] When in use, the changes of the tooth body 903 in the limiting groove 904 are all carried out under the limiting sliding of the limiting groove 904 at the position of the limiting rod 905.

[0038] Reference Figure 1 , Figure 2 and Figure 5 The guide assembly 1010 includes a circular ring 1011 fixed at one end of the disc 800. The circular ring 1011 is made of a steel circular iron plate. The circular ring 1011 is inclined to open a guide groove 1012 between the die 900. The use of the guide groove 1012 is convenient for the export of the stripped debris and the determination of the export direction. Blocks 1013 are fixed on both sides of the guide groove 1012. The use of the block 1013 facilitates the setting of the blade 1014 and the support spring 1015. The block 1013 is rotated A blade 1014 is connected, and the inclination line of the blade 1014 deviates from the center of the disc 800, and the debris in strips is discharged from between the blades 1014. When stuck, it is only necessary to rotate the chuck 300 in the opposite direction to retract the debris in strips, so that the blades 1014 are close to each other, and then the debris in strips is cut off, so that the debris in strips is no longer stuck and can be used normally. A support spring 1015 is connected between one side of the blade 1014 and the block 1013, and the position of the blade 1014 can be maintained by using the support spring 1015.

[0039] During use, the stripped chips are discharged from the guide groove 1012 and enter between the blades 1014. When stuck, the chuck 300 is rotated in the opposite direction to retract the stripped chips. The retraction of the stripped chips drives the blades 1014 to rotate in opposite directions, thereby cutting off the stripped chips. The chuck 300 is then rotated forward for normal thread processing. The stripped chips pass between the blades 1014. When passing through, the support spring 1015 will be squeezed to a certain extent, thereby increasing the distance between the blades 1014 to prevent the stripped chips from being blocked by slight deformation, so as to facilitate normal use.

[0040] Reference Figure 1 A support assembly 1020 for supporting the round steel pipe is vertically fixed to one end of the middle part of the slide plate 600 away from the material guide assembly 1010. The support assembly 1020 can be used to support the round steel pipe during thread processing to prevent the round steel pipe from being squeezed during thread processing and causing deformation at the processing location.

[0041] Reference Figure 1 , Figure 3 , Figure 6 and Figure 7 The support assembly 1020 includes a support rod 1021 fixed to the middle of the skateboard 600. The use of the support rod 1021 facilitates the installation of the connecting plate 1022. A connecting plate 1022 is provided on one side of the top of the support rod 1021. The ends of the connecting plate 1022 are fixed with elastically contractible springs 1023 on both sides. Protective accessories such as protective covers are attached to the outer sides of the springs 1023. Extrusion springs 1024 are connected between the two sides of the springs 1023 and the two sides of the middle of the connecting plate 1022. By using the extrusion springs 1024, the two sides of the springs 1023 can be kept in an elastically lifted state. The extrusion springs 1024 are made of stainless steel, and other materials require rust-proof covers on the outer sides.

[0042] When in use, the end of the round steel pipe is inserted into the outside of the spring piece 1023, and the two sides of the spring piece 1023 are elastically supported by the compression spring 1024. Since the two sides of the spring piece 1023 can change in size, it can adapt to the use of round steel pipes of different sizes.

[0043] Reference Figure 1 , Figure 3 , Figure 6 and Figure 7 A turntable 1025 that can move up and down is connected between the top side of the support rod 1021 and the connecting plate 1022. The turntable 1025 can be made directly of bearings, as long as the outer ring and the inner ring are respectively fixed on the support rod 1021 and the connecting plate 1022, but a limiting structure needs to be added.

[0044] When in use, by using the turntable 1025, the spring piece 1023 can rotate along with the round steel pipe.

[0045] Reference Figure 1 The rear side of the top of the slide plate 600 is rotatably connected with a pipe cutter 1030 for cutting round steel pipes, which can facilitate the length selection of the round steel pipes after thread processing and is practical for cutting.

[0046] When in use, after the thread processing is completed, the round steel pipe of a suitable distance is cut by the pipe cutter 1030.

[0047] The pipe cutter 1030 includes a slide bar rotatably connected to the rear side of the top end of the slide plate 600, and a clamping plate with a limiting function and a cutting knife are relatively slidably connected to the slide bar.

[0048] When in use, the distance and position between the cutting knife and the clamping plate can be adjusted by adjusting the clamping plate and the cutting knife on the sliding rod, so as to facilitate the use of round steel pipes of different sizes.

[0049] An external gear is provided at the bottom of the slide rail 500, a rotating rod is connected to the bottom of the slide plate 600, and a gear is meshed at the outer side of the rotating rod at a position corresponding to the external gear.

[0050] When in use, the rotation of the rotating rod drives the gear to rotate, and the rotation of the gear drives the slide plate 600 to move back and forth on the slide rail 500 through the gear meshing.

[0051] Usage process: first, according to the size of the round steel tube, the telescopic member 907 is extended or retracted, and the position of the fixing plate 901 on the disc 800 needs to be adjusted to adapt to the several teeth 903 caused by the curvature change to be at the same center position, and then the round steel tube is passed through the chuck 300 and the fastening disk 400, so that the end of the round steel tube is inserted into the outer position of the spring piece 1023; during processing, the strip-shaped debris is discharged from the guide groove 1012 and passes between the blades 1014. When the column is stuck, you only need to rotate the chuck 300 in the opposite direction to make the blade 1014 cut off the strip-shaped debris of the stuck column. It is easy to use.
