Abstract

The utility model discloses an inserted handle hammerhead, comprising a hammerhead body and a hammer handle, wherein the hammer handle is inserted into the inside of the hammerhead body; a through hole is punched in the connected part of the hammer handle and the hammerhead body; a pin shaft is inserted into the through hole and fixes the hammer handle and the hammerhead body together with a movable block. The condition that a hammer crusher safely and reliably runs is ensured by a design of connecting the movable block, the pin shaft and a cotter pin into a whole; just the hammerhead body needs to be quickly exchanged or replaced when the inserted handle hammerhead is in maintenance, so that metal material consumption is greatly reduced and the labor intensity of a worker is greatly lightened. In order to ensure that the hammerhead body does not crack in the rotation process, the hammer handle is welded by excellent A3 steel, the movable block adopts forged 45# steel, the pin shaft and the cotter pin adopt 35# steel, and are rigidly and mechanically connected with the hammerhead body, the hammerhead hardness is HRC60-64 after thermal treatment, the impact toughness is 8-10J/cm<2>, the inserted handle hammerhead has high comprehensive wear-resisting property, and the service life is 2-3 times that of ordinary alloyed steel, and is 3-4 times that of the traditional high manganese steel.

Description

A kind of inserting handle formula tup

Technical field

The utility model relates to a kind of tup of broken clinker, is specially a kind of inserting handle formula tup.

Background technology

Tup in existing equipment is easily fracture under high-intensity operation, changes the high and progress that dallies over one's work of tup expense, and labor strength is large, loses time.

Utility model content

The purpose of this utility model is to provide a kind of inserting handle formula tup, to solve tup in prior art, easily ruptures, and changes the high progress that dallies over one's work of tup expense, and labor intensity is large, the problem of losing time.

In order to achieve the above object, the technical scheme that the utility model adopts is:

An inserting handle formula tup, includes tup and hammer handle, and it is inner that described hammer handle inserts tup, and hammer handle and tup coupling part are equipped with through hole, and bearing pin inserts in through hole and together with loose piece, hammer handle and tup is fixed together.

Described a kind of inserting handle formula tup, is characterized in that: described bearing pin afterbody is equipped with split pin.

Described a kind of inserting handle formula tup, is characterized in that: described tup working position, for outside sweep circular-arc.

The utility model has the advantages that:

The design linking into an integrated entity by loose piece, bearing pin, split pin, guarantee that hammer mill running is safe and reliable, during maintenance, only need Quick-changing or change tup, greatly reducing metal material consumption and labor strength, for guaranteeing not rupture in tup operation process, hammer handle adopts the welding of high-quality A3 steel, loose piece adopts and forges 45# steel, and bearing pin and split pin adopt 35# steel, are connected with tup rigid mechanical, tup hardness HRC60 ~ 64 after heat treatment, impact flexibility 8 ~ 10J/cm ², there is higher comprehensive anti-wear performance, be common steel alloy service life 2 ~ 3 times, 3 ~ 4 times of traditional potassium steel.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Fig. 2 is side sectional view of the present utility model.

The specific embodiment

Referring to accompanying drawing.An inserting handle formula tup, includes tup 1 and hammer handle 2, and described hammer handle 2 inserts tup 1 inside, and hammer handle 2 and tup 1 coupling part are equipped with through hole, and bearing pin 4 inserts in through hole and together with loose piece 3, hammer handle 2 and tup 1 is fixed together.

Described bearing pin 4 afterbodys are equipped with split pin 5.

Described tup 1 has passed through the heat treatment that 3 ~ 5min+whole wind is quenched 5 ~ 10min+ high tempering, 4 ~ 6h of quenching of whole mist, and tup hardening heat is 1000 ~ 1020 ℃, and temperature is 450 ~ 500 ℃, and tup Q-tempering is organized as acicular martensite+eutectic carbide M ₇c ₃ten proeutectoid carbides+retained austenite.

Described tup 1 working position, for outside sweep circular-arc.
