Abstract
The invention relates to a crochet head cam of powder metallurgy, which mainly comprises two circular tube sleeves, the sections of which are obliquely anastomotic. The cam is made of hard alloy of powder metallurgy by die-casting. The outer wall of an inner mandrel of each circular tube of the cam is provided with a vertical groove; and a crochet hook is embedded into the groove. When an outer mandrel of the cam rotates, even if the crochet hook moves up and down along a track between cams, the purpose of prolonging the service life of the cams is achieved because the strength of the cam is enhanced. The crochet head cam of powder metallurgy has simple casting technology, abrasion resistance, largely enhanced working efficiency and prolonged service life.
Description
Technical field
The present invention relates to a kind of manufacturing material of crochet head cam, specifically a kind of crochet head cam of powder metallurgy.
Background technology
At present, mostly crochet head cam commonly used is the steel pipe by 45#, mills with anti-shape milling machine to be slit into shape, and its technology is comparatively complicated, and because crochet hook motion up and down for a long time, cam very easily weares and teares, and generally can only use 2-3, has caused waste.
In order to solve existing the crochet head cam difficult and problem easy to wear of technology in use, the present invention proposes an a kind of crochet head cam of powder metallurgy, this cam forms with the alloy powder casting, the crochet head cam of powder metallurgy of carbide alloy material, this cam casting technique is simple, its abrasion strength resistance can improve 2-4 doubly, has improved its operating efficiency greatly, has prolonged the service life of crochet head cam.
The technical solution adopted for the present invention to solve the technical problems is: this powder metallurgy crochet head cam mainly is made up of the pipe cover that two cross sections tilt to coincide; The material of this cam is to be that material forms through die casting with the carbide alloy that the powder smelting is closed; The outer wall of this cam pipe inner spindle has vertical groove, the embedded crochet hook that hangs with of groove; When the outer mandrel of cam rotates, even crochet hook moves up and down along the track between the cam, because the reinforcement of the intensity of cam, thereby reached the purpose that prolongs its service life.
Beneficial effect of the present invention: this crochet head cam of powder metallurgy casting technique is simple, wear-resistant, has improved its operating efficiency greatly, can prolong the service life of crochet head cam.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the example structure schematic diagram of this crochet head cam of powder metallurgy.
Among the figure, 1. crochet hook, 2. mandrel, 3. cam, 4. head cover.
The specific embodiment
In the drawings, this powder metallurgy crochet head cam mainly is made up of the round tubular casing that two cross sections tilt to coincide; The material of this cam 3 is to be that material forms through die casting with the carbide alloy that the powder smelting is closed; The outer wall of these cam 3 pipe inner spindle 2 has vertical groove, the embedded crochet hook 1 that hangs with of groove; When the outer mandrel of cam 3 rotates, even crochet hook 1 moves up and down along the track between the cam 3, because the reinforcement of the intensity of cam 3, thereby reached the purpose that prolongs its service life.
Claims (1)
