Introduction Of Homar Locking Plier

1: What is a strong clamp?

English name locking pliers, is mainly used for clamping parts for riveting, welding, grinding and other processing, which is characterized by jaws can be locked and produce a large clamping force, so that clamped parts will not loosen, and the jaws have a lot of gear adjustment position, for clamping different thickness parts to use, in addition to wrench use

Commonly used strong pliers have: generally strong pliers, sharp mouth with bladed strong pliers, welding with strong pliers, iron strong pliers, C-type strong pliers, chain-type strong pliers, arc teeth plus hard and strong pliers, straight teeth plus hard and strong pliers, sharp mouths with hard and strong pliers

2: The material of the strong clamp

(1) Chromium steel, chemical symbol CRV, is the quality of steel is relatively high-grade, the price is also relatively high;

(2) carbon steel, the quality is relatively poor, now on the market this material is the most, the price is also relatively low

3: Production process

(1) Steel forging

(2) Rough shaping (thick and thin repair) - drilling center holes - rough scraping (to smooth the fit)

(3) Molding milling (milling back, teeth, round, rear teeth) - fine scraping (smooth flat size accurate)

(4) Two pieces match - bevel (milling edge) - knife - press rivets

(5) fitter type (wrong finishing of the edge) - grinding type (grinding wheel rivet grinding, grinding shape, grinding fine neck) - head eye

(6) White whole (clamp handle flatness, rear open gear size, mouth gap)

(7) Heat treatment (HRC42 or more)

(8) Black whole (flexibility and swing) - fine grinding (both sides)

(9) Edge high frequency heat treatment (HRC48-50)

(10) Polishing

(11) Oil packaging

5: Hardness requirements

Clamp HRC42-48, Rivet HRC45-48, Blade HRC54-62, Head HRC44-48

6: The characteristics of the strong pliers

1, the characteristics of the pliers: jaws with chrome tantalum steel or carbon steel overall forging, good toughness, stamping steel plate handle, clamping objects do not deform, heat treatment adjustment rod, easy to adjust the best size and not deformation, jagged jaws, clamp holding force.

2, sharp mouth with bladed strong pliers, welding with strong pliers, iron pliers, C-type strong pliers, chain-type strong pliers characteristics: jaws with chrome tantalum steel or carbon steel as a whole forging, good toughness;

7: The specification of the pliers

Common tong specifications are: 5", total length: 127MM, 6" total length: 165MM; 7", total length: 175MM; 8", total length: 203MM ;9", total length: 228MM; 10", total length: 254MM; 11", total length: 279MM;
