Description
Technical field
The present invention relates to dumbbell technical field, specifically a kind of dumbbell and preparation method thereof.
Background technique
Dumbbell is a kind of auxiliary appliance of weight lifting and exercise, and silent when because of practice is named dumbbell.Current dumbbell
There are mainly three types of production technologies, first is that casting dumbbell: first iron powder melting, then polishing in casting surface, finally carries out surface
Chromium plating；Second is that cement dumbbell: being first blow molded a plastic housing, then the fill concrete inside plastic housing；Third is that clean steel dumbbell:
Steel plate is cut into dumbbell plate, and then dumbbell plate carries out surface polishing, last chromium plating again.
There are the following problems when current dumbbell produces: 1, cast dumbbell: production technology is complicated, and production process is to water and ring
The damage ratio in border is more serious；2, cement dumbbell: small product size is bigger, not firm enough after formed product, is easy breakage；3, clean steel
Dumbbell: production efficiency is low, and production cost is excessively high.
Summary of the invention
The purpose of the present invention is to provide a kind of dumbbells and preparation method thereof, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the invention provides the following technical scheme:
A kind of dumbbell, the raw material including following parts by weight: 95-99 parts of iron powder, 1-5 parts of tackifying resin powder.
As a further solution of the present invention: the raw material including following parts by weight: 96-98 parts of iron powder, tackifying resin powder
2-4 parts.
As a further solution of the present invention: the raw material including following parts by weight: 98 parts of iron powder, 2 parts of tackifying resin powder.
As a further solution of the present invention: the tackifying resin is EVA.
A kind of preparation method of dumbbell, comprising the following steps:
(1) raw material is weighed by weight and is mixed, and mixture is obtained；
(2) mixture is put into mold and is pressed into dumbbell plate model；
(3) dumbbell plate model is put into heating equipment heating, then cooled down；
(4) shell is prepared；
(5) step (3) dumbbell plate model after cooling is put into shell and fixation.
As a further solution of the present invention: the step (3) is that dumbbell plate model is put into heater box to be heated to 75-95
DEG C and keep the temperature 10-30min, then natural cooling.
As a further solution of the present invention: the step (4) is to prepare to match with dumbbell plate model by injection molding machine
Plastic shell, or stamp out the shell matched with dumbbell plate model with stainless steel.
As a further solution of the present invention: being fixed as being screwed in the step (5).
Compared with prior art, the beneficial effects of the present invention are: simplifying production technology, production process does not pollute, and protects
Environment and water source are protected；Production cost reduces 50%, and production cost is low；High production efficiency, product are sturdy and durable.
