Abstract
The invention discloses a manufacturing process of a wear-resisting guide plate of a puncher. The preparation process comprises the following steps of: producing the guide plate of the conventional puncher; machining straight-round-hole-shaped grooves in a working arc surface (used for being contacted with blanks) of the guide plate of the conventional puncher; injecting prepared ceramic slurry into the grooves; putting the guide plate injected with the ceramic slurry into a sintering furnace, carrying out sintering, hardening the ceramic slurry to form ceramic blocks, and manufacturing the wear-resisting guide plate; and carrying out polishing and trimming on the surface of the wear-resisting guide plate, and realizing smooth transition between each ceramic block and the guide plate working arc surface. The preparation process of the wear-resisting guide plate of the puncher has the beneficial effects that the hardness, the abrasion performance and the heat resistance of a contact surface of the guide plate with the blanks are enhanced by the wear-resisting guide plate of the puncher; the wear-resisting guide plate of the puncher not only has strength and toughness of metal and but also has high hardness and smoothness of ceramic, and the abrasion performance of the wear-resisting guide plate of the puncher is greatly improved; and the adhering steel degree is decreased, the service life is prolonged, and the surface quality of a produced tubular billet is improved.
Description
Technical field
The present invention relates to punch and Wear-resistant guide plate preparing technical field.
Background technology
When producing hollow billet with punch, the guide plate of punch, roll and top form the pass of annular jointly, and solid blank perforated machine passes hollow hollow billet.The Main Function of its centering guide is the lateral flow of restriction metal, impels metal axial to extend.In production process, blank temperature is more than 1000 DEG C, and is that spiral advances in the pass of punch formation, and guide plate not only bears the effect of high temperature, and is subject to serious frictional force; Also there is the phenomenon of steel bonding, wearing and tearing aggravation when producing stainless steel, cause hollow billet blemish to increase.Due to the working environment very severe of guide plate, it is consumable accessory comparatively outstanding in punch.
The guide plate that current domestic manufacturer uses mostly is nickelic high chromium or high carbon and chromium type, and wherein nickelic chromium type high guide plate cost is higher, and easily producing fracture when boring a hole stainless steel, high-alloy steel blank, causing hollow billet defect, production efficiency reduces; And high carbon and chromium type guide plate easily produces the defect such as steel bonding, pattern cracking.
Summary of the invention
The technical problem to be solved in the present invention is to provide the preparation technology of the punch Wear-resistant guide plate that a kind of hardness is high, wearability is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A preparation technology for punch Wear-resistant guide plate, its method step is as follows:
(1) forging type is adopted to produce guide plate of perforating machine;
(2) in the guide plate work cambered surface of above-mentioned guide plate of perforating machine, the groove that more than 3 spacing are equal is processed;
(3) ceramic size be equipped with is injected in the groove processed, ensure that the upper surface of ceramic size and guide plate work cambered surface seamlessly transit;
(4) the above-mentioned guide plate having injected ceramic size is put into sintering furnace to sinter, ceramic size is hardened and forms ceramic block, prepare Wear-resistant guide plate;
(5) is carried out polishing, repairing in the surface of the above-mentioned Wear-resistant guide plate prepared, realize seamlessly transitting of ceramic block and guide plate work cambered surface.
Described step (2) further groove is cylinder shape groove, and diameter is 10mm-20mm, the degree of depth is 20mm-25mm, spacing is 10mm-20mm.
Described step (2) further groove is truncated cone-shaped groove, and top diameter, base diameter are 10mm-20mm, and base diameter 2mm-3mm larger than top diameter, the degree of depth is 20mm-25mm, spacing is 10mm-20mm.
Groove in described step (2) centering guide work cambered surface adopts forging type and guide plate to process simultaneously, first prepares the core of groove, then casts out the groove in guide plate work cambered surface further.
Beneficial effect of the present invention is as follows:
(1) pottery being evenly distributed with bulk in the cambered surface contacted with blank of punch Wear-resistant guide plate, add the hardness of guide plate and blank contact surface, wearability and heat resistance, add the fineness of guide plate work cambered surface simultaneously, thus reduce frictional force, reduce the axial flow resistance of metal during perforation, the axis being beneficial to metal extends;
(2) punch Wear-resistant guide plate of the present invention not only has intensity, the toughness of metal, and has both the high rigidity, the smoothness that there are pottery, substantially increases its wearability.Compared with traditional guide plate of perforating machine, punch Wear-resistant guide plate of the present invention reduces steel bonding degree, extends service life, improves the surface quality of the hollow billet that it is produced.
