Description

Technical Field

[0001] The present invention relates to the field of metal workpiece drilling, and particularly to a metal drilling processing device. Background Art

[0002] When drilling a metal workpiece with soft texture and thin thickness, it is necessary to configure a cushion material to provide corresponding support for the metal workpiece as much as possible. That is, for example, when a drill with a drill bit impacts the metal workpiece, at the moment when the drill bit contacts the metal workpiece, the downward pressure given by the drill bit will cause a concave mutation in the contacted area of the workpiece. Accordingly, placing the cushion material on the opposite side of the contacted position to provide corresponding support can effectively improve the situation of concave mutation.

[0003] As described above, thin pipes made of stainless steel are very common in the drilling process with concave mutation at the contacted position by the drill bit. In this regard, reducing the impact speed is used to improve the mutation situation, but generally speaking, the effect is not clear enough, and there is no exact standard for how to configure different impact speeds for different pipes, and the implementation situation is unclear. Therefore, in combination with the above, taking metal pipes as an example, a metal drilling processing device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a metal drilling processing device to solve the technical problem that when drilling a metal pipe fitting with soft texture and thin thickness, it is easy to generate a concave mutation.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: A metal drilling processing device includes a lifting member, which has a fixed part and a movable part inserted above the fixed part. Among them, the fixed part and the movable part are respectively provided with a platform frame and a supporting column extending outward in the same direction, and a drill is arranged on the platform frame along the height direction of the lifting member and points to the supporting column. Both sides of the drill are configured with a support frame, and the end of the support frame pointing to the supporting column is provided with a clamping part spanning the supporting column. The clamping part has elasticity and is used to tightly press the pipe fitting arranged at the supporting column and combine with the drill to drill the pipe fitting when the movable part retracts into the fixed part.

[0006] Preferably, the pipe fitting is inserted at the supporting column, and the clamping part is always located in the area above the supporting column.

[0007] Preferably, the support frame is movable at the platform frame. Among them, the support frame has a sliding table spanning the platform frame and brackets installed at both ends of the sliding table and extending downward. The sliding table is slidably matched with the platform frame, and the downward extending ends of the two brackets respectively pull one end of the clamping part to make the clamping part span above the supporting column.

[0008] Preferably, a blowing member is provided between the bracket and the clamping portion. The blowing member includes a pushing block that slides in the height direction of the bracket and an airbag disposed within the sliding path of the pushing block. The airbag has a nozzle with its end pointing towards the punching location.

[0009] A pull rod is provided between the pushing block and the clamping portion, with both ends of the pull rod rotatably connected to the pushing block and the clamping portion respectively. When the movable portion retracts into the fixed portion, the clamping portion squeezes the pushing block and compresses the airbag, forcing the air in the airbag through the nozzle to the punching location.

[0010] Preferably, the airbag is located above the pushing block, and there is an elastic member within the airbag. When the pushing block releases the extrusion of the airbag, the elastic member expands the airbag to make the airbag inhale and reset.

[0011] Preferably, a rotating pipe member is provided at the clamping portion, passing through one end of the clamping portion and extending outward from the other end of the clamping portion. The rotating pipe member is movable within the clamping portion, and is exposed outward at the middle of the clamping portion and contacts the pipe member prior to the clamping portion.

[0012] Preferably, the bench includes a bench body and a plurality of screw perforations arrayed along the length direction of the bench body. Any one of the plurality of screw perforations is the fixing position of the drilling rig.

[0013] Preferably, the drilling rig includes a drilling rig body with the drill bit pointing towards the supporting column and a screw rod mounted on the other end of the drilling rig body in the opposite direction. The screw rod passes through the screw perforation and extends upward relative to the bench body. The upward extending portion of the screw rod is surrounded by a locking nut to fix the drilling rig body below the bench body.

[0014] Preferably, the lifting member is one of a hydraulic lifter or a pneumatic lifter. The fixed portion is a cylinder body, and the movable portion is a push rod. The push rod is inserted into the cylinder body and extends outward or retracts into the cylinder body relative to the cylinder body under the action of oil pressure and air pressure.

[0015] Preferably, a base is installed at the bottom of the fixed portion, and the base extends in the same direction as the supporting column and the bench.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, the pipe is placed on the supporting column. During the punching process, in combination with the action of the lifting member, the downward pressure is exerted by tightly pressing the clamping portion against the pipe. After determining the specific punching location on the pipe, the specific punching location is aligned with and contacts the supporting column. With the pressing of the clamping portion, the determined position is fixed, and then the drilling rig drills the specific punching location.

[0018] 2. After the clamping part contacts the pipe, the pull rod serves as the supporting part in the present invention, causing the pushing block to move upward relative to the continuously pressing bracket, thereby squeezing the airbag, and making the air in the airbag spray to the drilling position through the snake tube.

[0019] 3. Taking the supporting column as the axis, the present invention uses a rope to contact the pipe and rotates the pipe by combining friction in the pulling rope. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0029] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] In this embodiment, a metal punching processing device is proposed, including a lifting member 11. Please refer to Figures 1-3 , the lifting member 11 is a hydraulic lifting member, which includes a cylinder block and two push rods inserted into the cylinder block. The push rods extend upward or retract into the cylinder block relative to the cylinder block under the action of oil pressure. Accordingly, the gantry 10 is installed at the heads of the two towing rods, and the supporting column 2 is installed at the cylinder block. It should be noted that the gantry 10 and the supporting column 2 extend in the same direction, and in addition, the gantry 10 and the supporting column 2 are parallel to each other;

[0032] Please refer to Figures 1-3 , a drilling machine 8 is arranged on the gantry 10 along the height direction of the lifting member 11 and points to the supporting column 2. In addition, supporting frames are arranged on both sides of the drilling machine 8 and installed at the gantry 10. The end of the supporting frame pointing to the supporting column 2 is provided with a clamping portion 4 that straddles the supporting column 2. For the clamping portion 4, it should first have elasticity, and second, it should always be located above the supporting column 2. Accordingly, when the push rod retracts into the cylinder block, the clamping portion 4 contacts and presses tightly the pipe fitting inserted at the supporting column 2 during the retracting movement, and combines with the drilling machine 8 to perform punching processing on the pipe fitting.

[0033] The above description elaborates on the entire structural configuration of how the pipe fitting is supported at the contact surface during pipe fitting punching in this embodiment, that is, first, the pipe is placed on the supporting column 2 (when the pipe diameter is larger than the diameter of the supporting column 2, the part above the center of the supporting column 2 is used to support the pipe), and second, during punching, in combination with the movement of the lifting member 11, the downward pressure is reflected by tightly pressing the pipe with the clamping portion 4. Thus, after determining the specific punching position on the pipe, the specific punching position is aligned with and contacts the supporting column 2, and in combination with the pressing of the clamping portion 4, the determined position is fixed, and the drilling machine 8 is combined to perform drilling processing on the specific punching position.

[0034] Embodiment 2

[0035] In this embodiment, a metal punching processing device is proposed, including a lifting member 11. Please refer to Figures 1-3 , the lifting member 11 is a hydraulic lifting member, which includes a cylinder block and two push rods inserted into the cylinder block. The push rods extend upward or retract into the cylinder block relative to the cylinder block under the action of oil pressure. Accordingly, the gantry 10 is installed at the heads of the two towing rods, and the supporting column 2 is installed at the cylinder block. It should be noted that the gantry 10 and the supporting column 2 extend in the same direction, and in addition, the gantry 10 and the supporting column 2 are parallel to each other;

[0036] Please refer to Figures 1-3, a drilling rig 8 is arranged on the gantry 10 along the height direction of the lifting member 11 and points to the supporting column 2. In addition, support frames are arranged on both sides of the drilling rig 8 and installed at the gantry 10. It should be noted that the support frames are movable at the gantry 10, and a clamping portion 4 spanning the supporting column 2 is provided at the end of the support frame pointing to the supporting column 2. For the clamping portion 4, it should first have elasticity, and secondly, it should always be located above the supporting column 2. Accordingly, when the push rod moves towards the cylinder body and retracts, the clamping portion 4 contacts and presses tightly the pipe fitting inserted at the supporting column 2 during the retraction movement, and the drilling rig 8 is combined to punch the pipe fitting.

[0037] Different from Embodiment 1, in this embodiment, the support frame is movable at the gantry 10, that is, considering that some pipes are not straight vertical pipes, accordingly, in order to better enable the clamping portion 4 to fasten the special-shaped pipes, by adjusting the relative position of the support frame to the gantry 10, the clamping portion 4 installed at the corresponding support frame contacts the special-shaped pipe at a more appropriate angle.

[0038] This embodiment is an expansion example of Embodiment 1. Specifically, the support frame has a sliding table 7 spanning the gantry 10 and brackets 6 installed at both ends of the sliding table 7 and extending downward. The sliding table 7 is slidably matched with the gantry 10, and the downward extending ends of the two brackets 6 respectively pull one end of the clamping portion 4, so that the clamping portion 4 spans above the supporting column 2.

[0039] Embodiment 3

[0040] In this embodiment, a metal punching processing device is proposed, including a lifting member 11. Please refer to Figures 1-3 , the lifting member 11 is a hydraulic lifting member, which includes a cylinder body and two push rods inserted into the cylinder body. The push rods extend upward or retract into the cylinder body relative to the cylinder body under the action of oil pressure. Accordingly, the gantry 10 is installed at the heads of the two drag rods, and the supporting column 2 is installed at the cylinder body. It should be noted that the gantry 10 and the supporting column 2 extend in the same direction, and in addition, the gantry 10 and the supporting column 2 are parallel to each other;

[0041] Please refer to Figures 1-3 , a drilling rig 8 is arranged on the gantry 10 along the height direction of the lifting member 11 and points to the supporting column 2. In addition, support frames are arranged on both sides of the drilling rig 8 and installed at the gantry 10. It should be noted that the support frames are movable at the gantry 10, and a clamping portion 4 spanning the supporting column 2 is provided at the end of the support frame pointing to the supporting column 2. For the clamping portion 4, it should first have elasticity, and secondly, it should always be located above the supporting column 2. Accordingly, when the push rod moves towards the cylinder body and retracts, the clamping portion 4 contacts and presses tightly the pipe fitting inserted at the supporting column 2 during the retraction movement, and the drilling rig 8 is combined to punch the pipe fitting.

[0042] Different from the embodiment 2, a blowing member 5 is arranged between the bracket 6 and the clamping portion 4. The blowing member 5 includes a push block 52 sliding along the height direction of the bracket 6, and an air bag 51 arranged in the sliding path of the push block 52. It should be noted that, please refer to Figure 2 The airbag 51 is combined with the coiled tube 9 at the hole punching position of the nozzle. In addition, the push block 52 has a first adapter end 53, the clamping portion 4 has a second adapter end 55, and a pull rod 54 is provided between the first adapter end 53 and the second adapter end 55. Accordingly, the two ends of the pull rod 54 are rotatably connected to the first adapter end 53 and the second adapter end 55 respectively, and then when the push rod is retracted and moved into the cylinder body, the clamping portion 4 pushes the push block 52 and squeezes the airbag 51, and squeezes the air in the airbag 51 to the hole punching position.

[0043] The punching place is usually accompanied by the generation of chips. Based on this, there is currently a method of combining a high-pressure air pump with a nozzle to perform air spraying treatment on the punching place. However, in this embodiment, after the clamping part 4 contacts the pipe, the pull rod 54 serves as a support part, so that the push block 52 moves upward compared to the bracket 6 that is constantly pressing down, thereby squeezing the air bag 51, so that the air in the air bag 51 is sprayed from the coil 9 to the punching place.

[0044] Different from Example 2, this embodiment makes corresponding improvements to the clamping portion 4, that is, a rotating tube member 3 is provided at the clamping portion 4, which passes through one end of the clamping portion 4 and extends outward from the other end of the clamping portion 4. The rotating tube member 3 is movable in the clamping portion 4, and the rotating tube member 3 is exposed outward in the middle of the clamping portion 4 and contacts the pipe before the clamping portion 4.

[0045] For details, please refer to Figure 5 and Figure 7 The clamping portion 4 includes a soft plate 42 and rope channels 41 arranged at both ends of the soft plate 42 with the middle of the soft plate 42 as the boundary. Accordingly, the rope 31 included in the rotating tube member 3 passes through the rope channel 41 on one side, emerges in the middle of the soft plate 42 and passes through the rope channel 41 on the other side again before emerging. At this point, the rope 31 is located below the soft plate 42, so that it can contact the pipe before the soft plate 42.

[0046] The improvement of the clamping part 4 is that the supporting column 2 is used as the axis, a rope 31 is used to contact the pipe, and the pipe is rotated based on the friction force when the rope 31 is pulled. Specifically, rope handles 32 are installed at both ends of the rope 31 to provide corresponding fulcrums for use when pulling the rope 31.

[0047] In Embodiments 1, 2, and 3, the test stand 10 used has a test stand body 102 and a plurality of screw perforations 101 arranged along the length direction of the test stand body 102. It should be noted that any one of the plurality of screw perforations 101 is a fixed position for the drill 8. For the drill 8, it includes a drill body 81 with a drill bit pointing to the support column 2 and a screw 83 mounted on the other end of the drill body 81 in the opposite direction. Among them, the screw 83 passes through the screw perforation 101 and extends upward relative to the test stand body 102. The upward extending part of the screw 83 is looped by a locking nut 82, so that the drill body 81 is fixed below the test stand body 102.

[0048] In Embodiments 1, 2, and 3, a base 1 is installed at the bottom of the cylinder block. It should be noted that the base 1 extends in the same direction as the support column 2 and the test stand 10.

[0049] In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under", and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0050] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
