Abstract
The present invention relates to a creeper tread used for a D 375 soil shifter, which belongs to the technical field of cast molding. The present invention is characterized in that the creeper tread is produced by a cast molding technology, reinforcing ribs and a strip-shaped platform for enhancing the base intensity of installation are added on the basis of the basic shape and the structure of an original rolling molding creeper tread, and the integral strength of the creeper tread through cast molding is enhanced so as to prevent cracks in use and overcome the disadvantages that the rolling molding creeper tread has complicated procedures, the section bars depend on import, large equipment is needed during production, and requirements for mass production are high. The manufacturing technology of the creeper tread of the present invention is simplified, the performance of products is superior, the price is low, and the present invention fills the domestic blank that a creeper tread used for a D 375 soil shifter can not be produced.
Description
The present invention relates to a kind of caterpillar block of casting, belong to the casting processing technique field.
At present, the manufacturer of caterpillar block in all parts of the country adopts import crawler belt steel profile, way by mill processing is produced caterpillar block, for some product, as D375 bulldozer of import etc., its caterpillar block is domestic still can not be produced, complete dependence on import, this not only makes the caterpillar block fetch long price, but also can not solve a difficult problem of producing urgent need, and Britain's publication number is the patent of GB 2 231 013, related a kind of vehicle that is used for endless track is especially for the caterpillar block of the vehicle of miniature toroidal crawler belt, though it is a kind of caterpillar block of casting, but should say to be applicable to small-sized caterpillar belt formula vehicle, can not solve the problem of earth mover caterpillar block fully.For this reason, we try out the way of the way replacement roll forming of casting, replace the caterpillar block that the caterpillar block section bar is produced the D375 bulldozer with silicon-manganese steel, find and be not so good as the people to be willing to through test, the caterpillar block of producing often ruptures, especially at the M in B district, two jiaos of N and porose place breaks are more, that have even firm changing, just rupture once on probation, the performance requriements of the caterpillar block of the basic former roll forming of out of reach, we tissue engineering technique personnel carry out earnest analytical study the manufactured parts size are measured for this reason, find that the intact gold of institute's workpieces meets the drawing requirement, illustrate that rupturing is not that the build guality mistake causes, neither problem be arranged material, but reason is arranged in addition, reach a conclusion by the force analysis to use: with the rolling undercapacity of casting the back part instead, fracture is so causes.How to improve the intensity of foundry goods, make its performance requriements that meets the caterpillar block each side, become and can replace the gordian technique difficult problem that rolling type is produced caterpillar block with casting.
Purpose of the present invention is exactly to solve the technical barrier of above-mentioned existence and the design plan of a kind of casting caterpillar block of providing for the public, particularly be applicable to the caterpillar block that the D375 bulldozer uses, this scheme has not only improved the intensity of foundry goods, eliminated the problem that foundry goods easily ruptures, and the caterpillar block that makes casting surpasses the caterpillar block of roll forming on performance, the price of caterpillar block is reduced significantly and solved the urgently needed problem of producing.
The present invention is achieved in that
The rectangle that is shaped as of the present invention, be about 609.6 millimeters, wide about 317.5 millimeters, two side plates upwarp one along one and have a downwarp and certain radian is all arranged, the plate that upwarps along have on one side one to lower convexity and with plate along neat main muscle such as parallel, high about 94 millimeters of main muscle, last seesaw have along the middle part two prevent chain bend the collision caterpillar block breach, breach is outer wide about 102.5 millimeters, two breach line of centerss are at a distance of about 192.5 millimeters, two holes that crawler belt is captiveed joint with the chain band are respectively arranged before and after in the middle of caterpillar block, the vertical axis in hole is apart from being about 82.5 millimeters up and down, horizontal shaft is apart from being about 35 millimeters, the lower surface of caterpillar block is provided with and increases the reinforced rib of caterpillar block intensity to lower convexity, reinforced rib is made up of the diagonal bar that a horizontal bar and two Eight characters separate, parallel with main muscle and the close one side on seesaw edge down of horizontal bar, two diagonal bars that link to each other with horizontal bar link to each other at horizontal bar homonymy the right and left and with main muscle respectively, upper surface at caterpillar block is provided with two bar shaped platforms that raise up that increase caterpillar block installation underlying strength, two bar shaped platforms are the Eight characters and distribute, and have up and down two caterpillar blocks captive joint the hole of using with chain on each bar shaped platform.The diagonal bar of reinforced rib and horizontal bar can be orthogonal, also certain leaning angle can be arranged.Caterpillar block is taked cast shaping process production, and its material is a silicon-manganese steel.
Advantage compared with prior art of the present invention is: 1. adopt casting to replace roll forming and produce the problem that caterpillar block has solved the long-term dependence on import of the rolling section bar of caterpillar block, the caterpillar block productive costs is reduced significantly, solved the urgent need of producing; 2. take casting to produce the blank that caterpillar block has been filled up domestic caterpillar block that can not production import D375 bulldozer etc., save a large amount of foreign exchanges; 3. replace roll forming production caterpillar block with casting production technology is simplified greatly, solved the production of roll forming caterpillar block and needed the big problem of production lot, no matter batch reason size can both be produced; 4. production facilities is simple, small business also can produce, and has broken away from the history that the large-scale factories and miness that only have main equipment in the past could be produced; 5. its performance of the caterpillar block of casting also is better than the caterpillar block of roll forming, makes the production of caterpillar block fundamentally break away from external control.
Description of drawings is as follows:
Fig. 1 is a front view of the present invention;
Fig. 2 is a upward view of the present invention.
Wherein: (1)--caterpillar block, (2)--on the caterpillar block seesaw along, (3)--under the caterpillar block seesaw along, (4)----breach, (6) caterpillar block are captiveed joint hole, (7)--reinforced rib, (8)--platform with chain for main muscle, (5).
Embodiment:
