Description

Technical Field

[0001] This utility model belongs to the field of flange processing technology, and in particular relates to a flange punching die. Background Technology

[0002] Flange punching mainly involves using a drilling machine to create bolt holes for connection on the periphery of the flange. The typical processing method is to use multi-axis drilling equipment to perform punching operations on the flange simultaneously, which results in high equipment processing efficiency.

[0003] When using multi-axis drilling equipment, a pressure plate mold and a support mold are generally required to work together to clamp the flange in the clamping groove between the pressure plate mold and the support mold. Existing molds used in multi-axis drilling equipment can only fix flat flanges. However, for flanges with necks, the structure of one end face makes it impossible for existing molds to provide a good clamping effect, which makes it impossible to use efficient multi-axis drilling equipment for punching operations.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a flange punching die, applied to the drilling process of flange part 400, where flange part 400 has a neck structure, such as... Figures 1-5 As shown, the flange punching die includes:

[0024] The pressure plate 100 and the support 200 are provided. The support 200 is provided with a main bearing groove 201 for supporting the flange 400. The outside of the support 200 is provided with a hydraulic mechanism for operating the lifting and lowering of the pressure plate 100. Under the action of the hydraulic equipment, the pressure plate 100 holds the end of the flange 400 away from the neck in the main bearing groove 201.

[0025] An auxiliary pressure cylinder 300 is assembled on a pressure plate 100. The pressure plate 100 includes a base plate 110 and a limiting mechanism for fixing the auxiliary pressure cylinder 300. The pressure plate 100 has a receiving hole 101, which communicates with a fixing cavity 301 in the auxiliary pressure cylinder 300. As the pressure plate 100 is lifted by the hydraulic equipment, the receiving hole 101 and the fixing cavity 301 are nested on the outer side of the necked end of the flange 400. The circumferential side of the receiving hole 101 is provided with several sets of drill holes 102 for accommodating the through-holes of a multi-axis drilling machine shaft.

[0026] In this embodiment, the receiving hole 101 helps the necked end of the flange 400 pass through the pressure plate 100, while the fixing cavity 301 in the auxiliary pressure cylinder 300 is adapted to the structure of the necked side of the flange 400. The fixing cavity 301 is pressed against the outer side of the necked flange 400. Under the pressing action of the hydraulic equipment, the pressure plate 100 causes the wall of the fixing cavity 301 to generate a pressing force on the flange 400, thereby completing the fixing action of the flange 400 and improving the fixing effect of the necked flange 400 during the drilling process.

[0027] The auxiliary pressure cylinder 300 has a locking slot 302 on its side wall. The limiting mechanism includes a sliding groove 130 around the receiving hole 101 and a T-shaped locking slider 140 inside the sliding groove 130. The locking slider 140 slides in the sliding groove 130 and is inserted into the locking slot 302. The pressure plate 100 and the auxiliary pressure cylinder 300 are engaged and connected by several sets of locking sliders 140. The height of the locking slot 302 is the same as the height of the locking slider 140, and the width of the insertion surface of the locking slot 302 is adapted to the widest part of the locking slider 140.

[0028] In this application, before processing, the auxiliary pressure cylinder 300 uses a fixed cavity 301 of appropriate specifications to fix the flange 400 as needed, thereby improving the fixing effect of the flange 400. At the same time, the auxiliary pressure cylinder 300 adopts a detachable structural design, which allows the auxiliary pressure cylinder 300 to be customized and adapted according to the structure of the stiffened side of the flange 400. As processing needs, the auxiliary pressure cylinder 300 with a fixed cavity 301 of different shapes can be replaced, thereby improving the structural applicability and reducing mold investment costs.

[0029] In a preferred embodiment of this invention, the sliding groove 130 is provided with a locking screw hole, the locking slider 140 is provided with a countersunk hole structure, and the locking slider 140 is provided with a locking bolt that is fixedly connected to the base plate 110 through the countersunk hole structure and the locking screw hole.

[0030] In this embodiment, as Figure 3 As shown, the sliding groove 130 is provided with four sets of locking screw holes; the locking screw holes are arranged in pairs to form different locking modules. When the locking slider 140 is fully retracted into the sliding groove 130, the locking bolt can be assembled in one set of locking modules. When the locking slider 140 extends out of the sliding groove 130 and is inserted into the locking slot 302 on the side wall of the auxiliary pressure cylinder 300, the locking slider 140 is assembled in another set of locking modules.

[0031] In this embodiment, the number of sliding grooves 130 and locking sliders 140 is at least two sets and they are distributed in a ring array on the ring side of the receiving hole 101. The locking sliders 140 are used to restrict the torsion of the auxiliary pressure cylinder 300 and prevent the auxiliary pressure cylinder 300 from rising.

[0032] In a preferred embodiment of this invention, the support 200 includes a base 210 and a transverse support plate 220. There are two sets of both the base 210 and the transverse support plate 220. The transverse support plates 220 are arranged opposite each other to form a main bearing groove 201.

[0033] In this embodiment, the overall structure of the support 200 is basically the same as that of the existing support. In the traditional technology, the base 210 and the transverse support plate 220 are mostly welded. In addition to welding, the base 210 and the transverse support plate 220 of this application can also adopt a bolt fixing structure, which makes it easy to replace the transverse support plate 220. When the outer diameter of the flange 400 changes, the transverse support plate 220 with the main bearing groove 201 that is compatible with the flange 400 can be replaced.
