Abstract
The invention provides a method for producing a pick formed by casting and mould pressing, which is finished by a blank casting working procedure 1, a mould pressing working procedure 2, a heat treatment working procedure 3 and a shaping working procedure 4. The method for producing the pick is convenient to produce, has high mechanical degree, ensured quality, good integrity and high production efficiency; an alloy can be blended according to the purpose of a pick body; the produced pick can form picks with various structures and purposes; in addition, the pick has regular and attractive appearance, high strength, wear resistance, no bending, no snapping, lightness and durability; and the invention is suitable for manufacturing and applying the pick bodies in the field of farm tool manufacture.
Description
Technical field
What the present invention proposed is the tool fabrication method of farm implements manufacture field, specifically casting, die forming system pick method.
Background technology
Before the present invention proposed, the employed pick of farm implements normally ironsmith forged and makes, and is divided into pick, pick body two parts.Pick partly encloses with the iron bar annular makes oblateness, and tip side adds hot adhesion with iron, and formation can be installed the pick of pick handle.And pick body part is made with the iron bar beating, and its both upper ends thereof leaves ear.It is with the close pick outside of the ear of pick body that the pick body combines with pick, heats in stove fire, when reaching the fusing point of iron, forges the pick that pick and pick body are connected in one in the junction of pick and pick body.Pick also often adopts the mode of welding to finish with being connected of pick body.
The shortcoming that the method for this system pick exists is, system pick complex procedures, and step is many; And pick and fracture or the disconnection easily of pick body part; The pick body adopts iron to make usually, and intensity is low, flexible distortion, also wearing and tearing easily; The pick body structure is simple, and single, is not easy to make as required shape.
Summary of the invention
In order to overcome the shortcoming of existing system pick method, the present invention proposes casting, die forming system pick method.This method solves the technical problem of being connected of pick and pick body and typing by the bad die forming then of casting.
The scheme that technical solution problem of the present invention is adopted is:
Pick is circular or oval conical tubular body, and its lower end is the big nose end of pick, and the upper end is the pick small bore end, be connected with the pick body in pick one side by the pick connecting portion, the front end of pick body is provided with face crosswise, forms flat oblique pick sword or pointed pick sword, and pick can be provided with pick body air flue on one's body.
(1), cast bad operation: make the blank die cavity according to pick shape, with No. 45 steel or contain the manganese wear-resistant steel furnace melting, be poured in the die cavity, after the cooling, molding becomes pick chaeta base naturally.
(2), mold pressing procedure: make the typing die cavity according to pick shape, pick chaeta base is heated to 1100-1300 ℃, insert in the typing die cavity, patrix is pressurizeed, make pick body formed by hydraulic press.
(3), heat treatment step: the pick body heat is handled, will be heated to 500-800 ℃ through the pick body that mold pressing is finalized the design after, be immersed in the middle of cold water or the cold oil, quench.
(4), the correction of the flank shape operation: will polish through the edge of the pick body that quenches, grind off the part of irregularity, simultaneously orthopedic, become finished product pick.
Good effect, the present invention makes the pick method and is convenient to produce in batches, the mechanization degree height, quality is guaranteed, and alloy can be allocated good integrity, production efficiency height according to pick body and function way.Made pick can form the pick of multiple different structure and purposes, and, neat appearance, attractive in appearance, the intensity height, wear-resisting, not crooked, do not fracture, light, durable.Suitable farm implements are made the manufacturing of field pick body and are used.

The specific embodiment
According to shown in Figure 1, pick 1 is circular or oval conical tubular body, its lower end is the big nose end 2 of pick, the upper end is a pick small bore end 3, be connected with pick body 5 in pick one side by pick connecting portion 4, the front end of pick body is provided with the face crosswise of putting down tiltedly, forms pick sword 6, can be provided with pick body air flue 5.1 in the front of pick body.
According to shown in Figure 2, pick is strip pick as strip.Be used for the dark article of Bao.
According to shown in Figure 3, pick is as strip, and both sides and upside are provided with groove on the pick body, forms pick body air flue 5.1.Be used for the dark and hard soil of Bao.
According to shown in Figure 4, pick body both sides have the pick body to outer arc limit 5.2.Be used for Bao and more shallow soil and the plant roots and stems of shovel.
According to shown in Figure 5, pick body both sides have the pick body to the outer arc limit, and its pick sword 6 is pointed.Be used for loose soil, or Bao gets and cut off the plant underground roots stem, also can be used for shovel time operation simultaneously.
The manufacture method of pick of the present invention
(1), cast bad operation: make the blank die cavity according to pick shape, with No. 45 steel or contain the manganese wear-resistant steel furnace melting, be poured in the die cavity, after the cooling, molding becomes pick chaeta base naturally.
(2), mold pressing procedure: make the typing die cavity according to pick shape, pick chaeta base is heated to 1100-1300 ℃, insert in the typing die cavity, patrix is pressurizeed, make pick body formed by hydraulic press.
(3), heat treatment step: the pick body heat is handled, will be heated to 500-800 ℃ through the pick body that mold pressing is finalized the design after, be immersed in the middle of cold water or the cold oil, quench.
(4), the correction of the flank shape operation: will polish through the edge of the pick body that quenches, grind off the part of irregularity, simultaneously orthopedic, become finished product pick.
Because pick manufacture method of the present invention can make pick be connected with pick body consubstantiality, compare with existing respectively forging pick method processed, the fracture of pick and pick body can not take place. And pick and pick body integral body are made for abrasion-resistant stee, the intensity height, and toughness is big, and is wear-resistant, in light weight, and result of use is good.
Can make the pick of multiple different structure, specification and purposes, and, neat appearance, attractive in appearance, the intensity height, wear-resisting, not crooked, do not fracture, light, durable.
The pick method processed that adopts is convenient to batch production, the mechanization degree height, and quality is guaranteed, and alloy can be allocated good integrity, production efficiency height according to pick body and function way.
The inventive method can be for the manufacture of Bao ground pick, Bao plant pick, and Bao medicinal material pick, Bao stubble pick, shovel ground pick is weeded and loosen the soil ground pick, the multiple pick such as standby ridge pick.
