Abstract
The utility model specifically provides a screw assembly type pick, and the screw assembly type pick is used for solving the problem that an existing pick is fixed by welding to result in severe energy source waste, repeated use unavailability, environmental pollution and low production efficiency. The screw assembly type pick comprises a pick main body and a hard alloy head, wherein the front end part of the pick main body is in a stepped structure with front side diameter being smaller than rear side diameter, an external thread is arranged on the side face of the front part of a stepped surface of the pick main body, the connecting position of the hard alloy head is in a conical structure with front side diameter being smaller than rear side diameter, and a thread fastening sleeve with interior being matched with the conical surface of the hard alloy head is screwed at the external thread of the pick main body. The screw assembly type pick provided by the utility model is reasonable and reliable in structural design, and the pick main body can be repeatedly used; the use efficiency of the pick is improved, and the pick is changed quickly to save time; meanwhile, a welding procedure is omitted in pick processing technique, thereby reducing the processing cost and improving the processing efficiency.
Description
Technical field
The utility model relates to coal mining machine and development machine pick, is specially a kind of assembly type pick that screws.
Background technology
Pick is comprised of pick body and the hard alloy head that is fixed on pick body head.Extensively the cutting tooth structure of sale is in the market, and the working portion of hard alloy head is cone, cone angle 60-130 °, and hard alloy head and pick body mating part are cylinder, hard alloy head is fixed by welding in the installing hole of pick body head.The defect of this structure is: 1, welding need to be heated to product the fully fusing of 950 ℃ of above rear scolders, and power consumption is very big, and energy waste is serious, does not meet the requirement of " economizing economy "; 2, the solder and flux that welding is used is expensive, and cost is higher, and welding is very high to the chemical composition composition requirement of solder and flux, and underproof solder and flux or wrong operation very easily cause the welding such as sealing-off, bubble to scrap; 3,, in welding process, borax is subject to have more dust after high temperature and smog produces, and is unfavorable for the healthy of operating personnel, does not meet the requirement of " environment affinity type society "; 4, welding processing process is slow, is unfavorable for the large batch of production of product; 5, in later stage use procedure, once sealing-off, hard alloy head will come off from pick body, and whole pick, by entirely ineffective, no longer has use value; 6, after welding, hard alloy head is difficult to from pick body, take out again, and in the pick that so a large amount of uses are scrapped, expensive hard alloy head is just difficult to again be reused, and has seriously wasted rare mineral resource.
Summary of the invention
The utility model for solve existing pick adopt be welded and fixed exist energy waste serious, can not recycling, contaminated environment and the low problem of production efficiency, a kind of assembly type pick that screws is provided.
The utility model is to adopt following technical scheme to realize: screw assembly type pick, screw assembly type pick, comprise pick body and hard alloy head, the leading section of pick body is the step structure that front side diameter is less than rear side diameter, and the anterior side of pick body cascaded surface is provided with external screw thread, the connecting portion of hard alloy head is the cone structure that front side diameter is less than rear side diameter, and this extracorporeal thread of pick place is screwed with screw threads for fastening cover inner and hard alloy head cone match.
By hard alloy head and with the change of pick body connected mode, make the replacing of hard alloy head quick and convenient, the change of screw threads for fastening cover and pick body leading section structure, guaranteed the firm position of hard alloy head, overcome existing pick adopt be welded and fixed exist energy waste serious, can not recycling, contaminated environment and the low problem of production efficiency.
The utility model reasonable in design is reliable, and pick body is reusable, and cost-saving approximately 40%; And improved the service efficiency of pick, and realize quick-replaceable, save time; In pick processing technology, saved welding sequence, cut down finished cost, improved working (machining) efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-pick body, 2-hard alloy head, 3-external screw thread, 4-screw threads for fastening cover.
The specific embodiment
Screw assembly type pick, comprise pick body 1 and hard alloy head 2, the leading section of pick body 1 is the step structure that front side diameter is less than rear side diameter, and the anterior side of pick body 1 cascaded surface is provided with external screw thread 3, the connecting portion of hard alloy head 2 is the cone structure that front side diameter is less than rear side diameter, and pick body 1 external screw thread 3 places are screwed with screw threads for fastening covers 4 inner and hard alloy head 2 cone match.
