Abstract
The utility model relates to a protection device for a drill bit resin mold in the petroleum drill bit manufacturing process, which is composed of a support cylinder, an upper end cover, a lower end cover and connecting bolts; the upper end cover and the lower end cover are respectively disposed above and under the support cylinder, wherein the upper end cover is fixed with the support cylinder through threads and the lower end cover is fixed with the support cylinder through a plurality of connecting bolts which are uniformly distributed along the circumference. The device is portable and repeatedly-usable and has low manufacturing cost, and strong universality; a set of the device is used for plural sets of the resin drill bit molds with the same size, thus not only meeting the process requirements, but also improving the utilization ratio of the device and decreasing the manufacturing cost for the drill bit.
Description
Technical field:
The utility model relates to a kind of protective device that is used for oil drilling diamond bit die manufacture.
Background technology:
Diamond bit is that oil drilling is used a kind of of drill bit, adopts usually not have to press to invade and steeps the sintering technology manufacturing.Drill bit mould rapid laser-shaping technique has greatly improved the accuracy of manufacture and the production efficiency of drill bit in the manufacturing successful Application of diamond bit.The mould that adopts rapid laser-shaping technique to produce is made of photosensitive resin material with high costs, and for saving cost, workpiece is often made thin-wall construction.Because resin die itself can not bear pulling force and pressure in the drill bit Mold Making process, need be embedded in the protective sleeve that is processed into by graphite or steel.Adopt these technologies to cause the workpiece heaviness, carrying and operating difficulties, and waste material, contaminated environment.
The utility model content:
The purpose of this utility model be to provide a kind of simply light, utilization rate is high, can reduce the drill bit resin die protective device of oil diamond bit manufacturing cost.
The utility model is to realize like this.This kind mould protective device is made up of support tube, upper end cover, bottom end cover, connecting bolt; its structure, assembled relation are as follows: the support tube upper and lower is respectively equipped with upper end cover and bottom end cover; wherein upper end cover fixes by screw thread and support tube, and bottom end cover is by being connected and fixed along circumferential uniform a plurality of connecting bolts.During use, embed in the bottom end cover end face groove bottom the resin former, cover upper end cover, adjusting upper end button is just fixed mould and is got final product.Can respectively join a cover protective device to the drill bit of several gauge size commonly used, can rotate the upper end for the mould of unidimensional differing heights and buckle and regulate height or replacing support tube, need not to replace with bottom end cover.Compare with previously used graphite overcoat, not only operate simple and easy, safety, not fragile, and can save a large amount of moulds.
The utility model simple light, cost of manufacture is low, highly versatile, and reusable, a covering device can be used for unidimensional many cover resin drill bit moulds to be used, and not only can satisfy arts demand, and can improve the utilization rate of device, reduces the drill bit manufacturing cost.
Description of drawings:
Accompanying drawing is a general structure schematic diagram of the present utility model.Number in the figure " 5 " is the resin former.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is applied explanation.
As shown in the figure, the utility model is made up of upper end cover 1, support tube 2, bottom end cover 3, connecting bolt 4.Wherein, support tube 2 is a cylinder, and its periphery upper end is provided with upper end cover and is connected with fine-tuning end button, and round platform upper edge, lower end circumferentially is evenly equipped with uses bolt hole a plurality of the connection with bottom end cover.Upper end cover 1 is bowl cover shape, and its inboard is provided with fine-tuning end button.Bottom end cover 3 is a hollow dome, and its periphery is evenly equipped with a plurality of connecting bolts hole, and end face is provided with the groove that is used to inlay the resin former.
