Description

Technical Field

[0001] The utility model belongs to the technical field of drilling dies, and in particular relates to a multi-diameter and multi-aperture tube wall drilling die. Background Art

[0002] At present, for the radial hole making operation of thin-walled small-diameter pipe fittings, the usual operation process is: first, manual marking is performed using a ruler and a stone pencil, then a sample punch is used to punch holes (or positioning points), and finally a drilling machine is used to drill holes.

[0003] This operation method is highly dependent on manual labor. Due to the errors in manual marking, if there are multiple diameter holes on the pipe wall, errors will accumulate, the relative position and size of the holes are difficult to guarantee, and the product qualification rate is low. Secondly, manual marking is time-consuming and labor-intensive, with a long production cycle and low efficiency. The drilling machine directly drills holes in thin-walled small-diameter pipes, which can easily cause the pipe wall to bend and deform, and the radial holes are prone to deviation. Utility Model Content

[0004] The utility model provides a multi-diameter and multi-aperture tube wall drilling die, and aims to solve the following technical problems: solving the problem that when radial holes are made on thin-walled small-diameter tubes, a process of manual marking, proofing and drilling is often used, resulting in low product qualification rate, low production efficiency, easy deviation of radial holes, easy deformation of thin-walled tubes and other problems.

[0005] In order to solve the above technical problems, the utility model provides a multi-diameter and multi-aperture pipe wall drilling mold, which is characterized in that it includes a base plate 1, a fixed support 2, a V-shaped block 3, a pressure plate 4, and a drill sleeve 7; the fixed support 2 is fixed on the base plate 1, the V-shaped block 3 is completely fitted with the V-groove at the upper end of the fixed support 2, and is fixed on the fixed support 2 for supporting the pipe fittings, the two ends of the pressure plate 4 are fixed on the fixed support 2, and a row of straight through holes is provided on the pressure plate 4, and the hole spacing is equal to the hole spacing on the pipe fittings; the drill sleeve 7 is installed in the straight through holes on the pressure plate 4.

[0006] Beneficial effects: The utility model eliminates the manual marking and proofing process, reduces the labor intensity of the operator, improves product quality, and improves production efficiency. At the same time, the versatility of the mold is guaranteed. The same mold can be used for drilling holes in pipes with a certain range of diameters. By replacing drill sleeves of different specifications, it can be used for radial hole processing of different diameters. It is suitable for drilling holes in thin-walled pipes with different diameters. By replacing the drill sleeve, it can also be used for drilling radial holes of different diameters. The device has many advantages such as accurate positioning, strong clamping, simple operation, low cost, and convenient maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below.

[0011] The utility model provides a multi-diameter and multi-aperture pipe wall drilling die, comprising a bottom plate 1, a fixed support 2, a V-shaped block 3, a pressing plate 4, a No. 1 slotted screw 5, a No. 2 slotted screw 6, and a drill sleeve 7;

[0012] The base plate 1 is fixed on the bench; there are three fixed supports 2, which are fixed at both ends and the middle position of the base plate 1 to support the pipe fittings; the V-shaped block 3 is completely fitted with the V-groove of the fixed support 2 and fixed on the fixed support 2 to adapt to pipe fittings of different diameters; both ends of the pressing plate 4 are installed on the fixed support 2 by means of No. 1 slotted screws 5. If the aperture on the wall of the produced pipe fitting has only one size specification, the pressing plate 4 and the fixed support 2 can also be fixed as one to make a special tooling mold. There is a row of straight through holes on the pressing plate 4, and the hole spacing is equal to the hole spacing on the pipe fitting; the drill sleeve 7 is installed in the straight through hole on the pressing plate 4, and is an interference fit with the straight through hole; there are three threaded holes on the pressing plate 4, and the pressing plate 4 presses the pipe fitting in the V-shaped block 3 through the threaded holes of No. 2 slotted screws 6 to prevent the axial movement of the pipe fitting.

[0013] The number of parts of the multi-diameter and multi-aperture pipe wall drilling mold is 1 base plate, 3 fixed supports, 3 V-blocks, 1 pressure plate, 4 No. 1 slotted screws, and 3 No. 2 slotted screws. The number of drill sleeves is not fixed and is the same as the number of holes on the pipe wall. The working angle of the V-block is 90°. There must be at least 2mm of clearance between the lower surface of the pressure plate and the outer wall of the pipe. The size of the lug structure at the connection between the fixed support and the pressure plate is designed and determined based on the maximum pipe diameter. The diameter of the straight-through hole on the pressure plate is designed based on the outer diameter of the drill sleeve, and is interference fit with the drill sleeve. The drill sleeve is replaceable and made into drill sleeves of various specifications with the same outer diameter and different inner diameters. In actual use, the drill sleeve specifications are selected according to the diameter of the hole to be drilled. The height of the drill sleeve is 1 to 3mm higher than the pressure plate.

[0014] The utility model is suitable for drilling operations of thin-walled pipe fittings with different diameters. By replacing the drill sleeve, it can also be suitable for drilling radial holes of different pipe fittings. The device has many advantages such as accurate positioning, strong clamping, simple operation, low cost and convenient maintenance.

[0015] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
