Description

Technical Field

[0001] The invention relates to the technical field of metal parts processing, in particular to a metal parts punching device. Background Art

[0002] Metal parts refer to the metal blocks, metal bars, metal tubes, etc. of various specifications and shapes made of metal materials;

[0003] When processing some common metal pipe parts, it is often necessary to punch holes on them to meet the needs of parts use;

[0004] As a type of metal tube, thin-walled round tubes are widely used in various mechanical products. However, due to the characteristics of thin-walled round tubes themselves, they have the following defects during the punching production process:

[0005] 1. Since the inner wall thickness of thin-walled round tubes is relatively thin, for example, when the diameter of air-conditioning copper tubes is 6 to 20 mm, the tube wall thickness is 0.3 to 0.7 mm, and the pressure resistance during the punching process is relatively poor. During the punching process, the hole position is very susceptible to the impact of the punching equipment, causing deformation and depression of the metal tube surface, affecting product quality;

[0006] 2. Due to the cylindrical structure of the thin-walled round tube, its conventional horizontal processing table cannot meet the fixing work during the punching process, and an additional clamp is required to clamp and fix it. The traditional clamps are divided into two ways of fixing thin-walled round tubes: external clamping and internal support. The external clamping (such as the clamping structure of the utility model with announcement number CN215616502U) is not easy to accurately control the clamping force. In order to achieve sufficient clamping and stabilization effect on the thin-walled round tube, the clamping force of the thin-walled round tube needs to be increased. Increasing the clamping force is easy to cause deformation of the outer wall. The internal support method requires manual adjustment, and the adjustment process is relatively cumbersome. The internal support components are easy to hinder the punching equipment, making it impossible to complete the punching operation.

[0007] Therefore, a metal parts punching device is proposed. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 11 , the present invention provides a technical solution:

[0040] A metal parts punching device, comprising a base 4, a processing cylinder 2 fixed on the base 4, a top cover 1 distributed on the upper side of the processing cylinder 2, the rear side of the processing cylinder 2 and the top cover 1 are fixedly connected via a side plate 13, a motor 41 is fixedly connected inside the base 4, a fixed seat 5 is fixedly connected inside the processing cylinder 2, and a rotating seat 6 is rotatably connected to the fixed seat 5, and the middle part of the lower end surface of the rotating seat 6 is connected to the output shaft of the motor 41;

[0041] The outer ring of the rotating seat 6 is provided with three fixing mechanisms 3 at equal distances, and the upper side of the rotating seat 6 is provided with a hole opening member 8 at a position corresponding to the fixing mechanism 3;

[0042] The fixing mechanism 3 includes a rotating member 33 rotatably connected to the rotating seat 6, a stretching member 32 movably connected to the rotating member 33, and a driving member 31 distributed in the stretching member 32. The driving member 31 is in contact with the extrusion plate 22 fixed to the inner wall of the processing cylinder 2, and a thin-walled round tube is sleeved on the outside of the stretching member 32 and the driving member 31.

[0043] Specifically, if Figure 5 picture, Figure 6 , Figure 7 and Figure 8 As shown, the outer surface of the processing cylinder 2 is provided with an opening 21, and the inner wall of the processing cylinder 2 is fixedly connected to the extrusion plate 22 of an annular structure at the corresponding position of the opening 21, and the extrusion plate 22 and the opening 21 are in an arc-shaped structure design corresponding to the opening 21, and the rotating member 33 includes a rotating disk 332 distributed outside the rotating seat 6, and a rotating shaft 338 is fixed in the middle of the rotating disk 332, and the rotating shaft 338 extends to the inner wall of the rotating seat 6 and is rotatably connected to the rotating seat 6, and the connecting part of the rotating shaft 338 and the rotating seat 6 is embedded in the inner wall. An electromagnet 2 337 is connected, an angle sensor 336 is embedded in the outer portion of the rotating seat 6 and is connected to the corresponding position of the turntable 332, a gear ring 1 331 is rotatably connected to the outer portion of the turntable 332, and an electromagnet 1 335 is arranged between the gear ring 1 331 and the turntable 332, a gear ring 2 334 is arranged on the outer side of the fixed seat 5 near the upper end and at a position corresponding to the gear ring 1 331 on the outer side of the turntable 332, and the gear ring 1 331 is meshedly connected with the gear ring 2 334, and the gear ring 2 334 is fixedly connected to the fixed seat 5.

[0044] By adopting the above technical solution, when the roller 87 moves to the groove 12, under the action of the spring 2 84, the drill rod 86 is separated from the thin-walled circular tube; then when the user needs to drill holes at different positions outside the thin-walled circular tube, the controller controls the electromagnet 2 337 to cut off the electromagnetic attraction, the electromagnet 1 335 is conductive, the gear ring 1 331 and the turntable 332 are magnetically fixed, so that when the rotating seat 6 rotates, the turntable 332 will rotate under the meshing action of the gear ring 1 331 and the gear ring 2 334, and the rotation angle data is collected by the angle sensor 336 and fed back to the controller, and the angle data is preset in the controller. When the data matches, the on and off states of electromagnet 1 335 and electromagnet 2 337 are automatically controlled to meet the angle rotation of the thin-walled circular tube, thereby realizing the hole opening operation at different positions on the surface of the thin-walled circular tube. It is worth noting that when the drill rod 86 is located in the drill hole of the thin-walled circular tube, the thin-walled circular tube cannot be rotated. Therefore, it is sufficient to collect the rolling data of roller 87. A sensor is also built into roller 87. Only when roller 87 is completely located in groove 12 can the rotating part 33 be controlled to operate. When the thin-walled circular tube does not need to be rotated, electromagnet 2 337 is in the on state and electromagnet 1 335 is in the off state.

[0045] Specifically, if Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , Fig.11 As shown, the stretching member 32 includes an annular slide groove 333 which is equidistantly arranged on the side of the turntable 332 away from the rotating seat 6, and a slider 322 is slidably connected in the slide groove 333, a spring 323 is fixed between the slider 322 and the slide groove 333, an arc-shaped stretching plate 321 is fixedly connected to the outside of the slider 322, and a hole groove 324 is arranged on the outside of the stretching plate 321, the slider 322 and the slide groove 333 are T-shaped and cannot be separated, the driving member 31 is located inside the three stretching plates 321 and is movably connected to the stretching member 32, the driving member 31 includes a connecting tube 311 with a hemispherical structure design at one end, and the inside of the connecting tube 311 is The connecting tube 311 is empty, and a connecting rod 313 is movably connected in the connecting tube 311. A spring three 314 is arranged in the connecting tube 311, and one end of the spring three 314 is fixed to the inner wall of the connecting tube 311, and the other end is fixed to the connecting rod 313. A conical disk 312 with a conical structure is fixed to the outside of the connecting tube 311, and the surface of the conical disk 312 on one side close to the connecting rod 313 is inclined. The inner walls of the three stretching plates 321 are designed at an inclined angle. A steel ball 315 is embedded in the hemispherical end of the connecting tube 311, and the steel ball 315 is arranged to fit the outside of the extrusion plate 22. The end of the connecting rod 313 away from the connecting tube 311 is fixed to the turntable 332.

[0046] By adopting the above technical solution, when working, first the external controller is connected with the power supply, electromagnet, angle sensor 336, and motor 41, and the controller controls the motor 41 to drive the rotating seat 6 to rotate, so that the fixing mechanism 3 on the rotating seat 6 corresponds to the opening 21 outside the processing cylinder 2, and then the user sleeves the thin-walled circular tube on the surface of the stretching member 32 and the driving member 31 on the fixing mechanism 3 through the opening 21, and then the motor 41 rotates counterclockwise to drive the rotating seat 6 and the fixing mechanism 3 with the thin-walled circular tube sleeved on the outside to rotate. During the rotation process, the connecting tube 311 at the hemispherical end of the driving member 31 contacts the extrusion plate 22 in the processing cylinder 2, and under the action of the hemispherical end of the connecting tube 311 and the steel ball 315, the connecting tube 311 is squeezed and displaced along the arc surface of the extrusion plate 22, and the connecting tube 311 is guided and displaced outside the connecting rod 313, and the connecting rod 313 moves relatively to extend to the inside of the connecting tube 311, and the movement process of the connecting tube 311 The cone disk 312 fixed on its surface moves together. Under the design of the outer inclination angle of the cone disk 312 and the action of the inner wall inclination angle of the support plate 321 in the support member 32, the three groups of support plates 321 are driven to expand outward under the sliding connection of the slider 322 and the slide groove 333 on the surface of the rotating disk 332. The slider 322 stretches the spring 1 323. At this time, the support plate 321 expands outward synchronously and contacts with the inner wall of the thin-walled circular tube sleeved on the outside and stretches and fixes it. The inner wall of the thin-walled circular tube after being stretched and fixed is supported by the support plate 321, and the stress at the punching place can be shared during the subsequent punching process of the hole opening member 8 to avoid stress concentration causing surface deformation at the punching place. The hole groove 324 designed on the outside of the support plate 321 is also matched with the hole opening member 8 to avoid the support plate 321 affecting the movement of the hole opening member 8 and affecting the hole opening. The hole groove 324 can be designed according to the size and shape of the thin-walled circular tube hole during actual use.

[0047] Specifically, if Figure 2 , Figure 7 , Fig. 9 and Fig.10As shown, a fixing column 71 is fixedly connected to the top of the rotating seat 6, and a fixing plate 7 is fixedly connected to the top of the fixing column 71. The upper end surface of the fixing plate 7 is movably connected to the opening member 8 at a position corresponding to the stretching member 32 in the lower fixing mechanism 3. The opening member 8 includes a fixing rod 81, and a movable groove 85 is provided at the bottom of the fixing rod 81. A drill rod 86 is threadedly connected to the inner thread of the movable groove 85. The outside of the fixing plate 7 passes through and is movably connected to the fixing rod 81. A guide groove 82 is provided inside the fixing plate 7, and a guide block 83 is movably connected in the guide groove 82. The guide block 83 is fixedly connected to the fixing rod 81, and a spring 2 84 is fixed between the guide groove 82 and the guide block 83. A roller 87 is rotatably connected to the top of the fixing rod 81. A protrusion 11 with an arc structure is fixed at a position corresponding to the roller 87 on the lower end surface of the top cover 1, and a groove 12 with an arc structure is provided on one side of the protrusion 11. The number of the protrusion 11 and the groove 12 is a plurality of intervals and is designed in a ring structure.

[0048] By adopting the above technical solution, after the stretching member 32 cooperates with the driving member 31 to stretch and fix the thin-walled round tube, the motor 41 continues to drive the rotating seat 6 and the thin-walled round tube to rotate and move in the processing cylinder 2. At this time, the upper side and the fixed disk 7 connected to the rotating seat 6 through the fixed seat 5 and the hole-opening member 8 on the fixed disk 7 move together. An hole-opening member 8 is set on the upper side of each fixing mechanism 3. When the hole-opening member 8 moves with the rotating seat 6, the top roller 87 contacts the lower end surface of the top cover 1. When the roller 87 contacts the protrusion 11 on the arc-shaped surface of the lower end surface of the top cover 1 as it moves, the roller 87 moves downward relatively. The fixing rod 81 is displaced, and then the fixing rod 81 cooperates with the guide block 83 and the guide groove 82 to move downward, and then the spring 2 84 is compressed. At this time, the drill rod 86 threadedly connected to the lower end of the fixing rod 81 moves downward to open a hole in the lower thin-walled circular tube. Since the drill rod 86 and the fixing rod 81 are threadedly connected, the user can conveniently adjust the common length of the drill rod 86 and the fixing rod 81 according to the thickness of the thin-walled circular tube. The subsequent user can also design the fixing rod 81 on the fixing plate 7 in the form of a strip plate, and selectively install the drill rod 86 at the threaded holes at different positions on the bottom of the corresponding fixing rod 81 to meet the needs of opening holes at different positions of the thin-walled circular tube.

[0049] Working principle: During operation, first, the external controller is connected to the power supply, electromagnet, angle sensor 336, and motor 41, and the controller controls the motor 41 to drive the rotating seat 6 to rotate, so that the fixing mechanism 3 on the rotating seat 6 corresponds to the opening 21 outside the processing cylinder 2, and then the user sleeves the thin-walled circular tube on the surface of the stretching member 32 and the driving member 31 on the fixing mechanism 3 through the opening 21, and then the motor 41 rotates counterclockwise to drive the rotating seat 6 and the fixing mechanism 3 with the thin-walled circular tube sleeved on the outside to rotate. During the rotation process, the connecting tube 311 at the hemispherical end of the driving member 31 contacts the extrusion plate 22 in the processing cylinder 2, and under the action of the hemispherical end of the connecting tube 311 and the steel ball 315, the connecting tube 311 is squeezed and displaced along the arc surface of the extrusion plate 22, and the connecting tube 311 is displaced and guided outside the connecting rod 313, and the connecting rod 313 moves relatively to extend to the inside of the connecting tube 311, and during the movement of the connecting tube 311, its The conical disk 312 fixed on the surface moves together. Under the design of the outer inclination angle of the conical disk 312 and the action of the inner wall inclination angle of the support plate 321 in the support member 32, the three groups of support plates 321 are driven to expand outward under the sliding connection of the slider 322 and the slide groove 333 on the surface of the rotating disk 332. The slider 322 stretches the spring 1 323. At this time, the support plate 321 expands outward synchronously and contacts with the inner wall of the thin-walled circular tube sleeved on the outside and stretches and fixes it. The inner wall of the thin-walled circular tube after being stretched and fixed is supported by the support plate 321. In the subsequent punching process of the hole opening member 8, the stress at the punching location can be shared to avoid stress concentration causing surface deformation at the punching location. The hole groove 324 designed on the outside of the support plate 321 is also matched with the hole opening member 8 to avoid the support plate 321 affecting the movement of the hole opening member 8 and affecting the hole opening. The hole groove 324 can be designed according to the size and shape of the thin-walled circular tube hole during actual use.

[0050] After the stretching member 32 cooperates with the driving member 31 to stretch and fix the thin-walled round tube, the motor 41 continues to drive the rotating seat 6 and the thin-walled round tube to rotate and move in the processing cylinder 2. At this time, the fixed disk 7 connected to the rotating seat 6 through the fixed seat 5 and the hole-opening member 8 on the fixed disk 7 move together. An hole-opening member 8 is set on the upper side of each fixing mechanism 3. When the hole-opening member 8 moves with the rotating seat 6, the top roller 87 contacts the lower end surface of the top cover 1. When the roller 87 contacts the protrusion 11 on the arc-shaped surface of the lower end surface of the top cover 1 as it moves, the roller 87 moves downward relatively, and then The fixing rod 81 cooperates with the guide block 83 and the guide groove 82 to move downward, and then the spring 84 is compressed. At this time, the drill rod 86 threadedly connected to the lower end of the fixing rod 81 moves downward to open a hole in the lower thin-walled circular tube. Since the drill rod 86 and the fixing rod 81 are threadedly connected, it is convenient for the user to adjust the common length of the drill rod 86 and the fixing rod 81 according to the thickness of the thin-walled circular tube. The subsequent user can also design the fixing rod 81 on the fixing plate 7 in the form of a strip plate, and selectively install the drill rod 86 at the threaded holes at different positions on the bottom of the corresponding fixing rod 81 to meet the needs of opening holes at different positions of the thin-walled circular tube.

[0051] When the roller 87 moves to the groove 12, under the action of the spring 2 84, the drill rod 86 is separated from the thin-walled circular tube; then when the user needs to drill holes at different positions outside the thin-walled circular tube, the controller controls the electromagnet 2 337 to cut off the electromagnetic attraction, the electromagnet 1 335 is conductive, the gear ring 1 331 and the turntable 332 are magnetically fixed, so when the rotating seat 6 rotates, the turntable 332 will rotate under the meshing action of the gear ring 1 331 and the gear ring 2 334, and the rotation angle data is collected by the angle sensor 336 and fed back to the controller. The angle data is preset in the controller. When the data matches The on and off states of electromagnet 1 335 and electromagnet 2 337 are automatically controlled to meet the angular rotation of the thin-walled circular tube, thereby realizing the hole opening operation at different positions on the surface of the thin-walled circular tube. It is worth noting that when the drill rod 86 is located in the drill hole of the thin-walled circular tube, the thin-walled circular tube cannot be rotated. Therefore, the rolling data of roller 87 can be collected. A sensor is also built-in inside roller 87. Only when roller 87 is completely located in groove 12 can the rotating part 33 be controlled to operate. When the thin-walled circular tube does not need to be rotated, electromagnet 2 337 is in the on state and electromagnet 1 335 is in the off state.

[0052] The purpose of spring one 323 and spring two 84 is to be used for subsequent reset;

[0053] When the processed thin-walled round tube moves to the opening 21 again after a circle of displacement, the hemispherical end of the connecting tube 311 corresponds to the opening 21 to squeeze it. At this time, the user can remove the thin-walled round tube through the opening 21.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
