Embodiment

[0033] Example: such as Figure 1-10 As shown, a clamping mechanism includes a clamping mechanism 10 and an impact mechanism 30. The clamping mechanism 10 includes a shift lever 11, a jaw base 13 and a jaw slide 15, and the jaw slide 15 is fixed on On the jaw base 13 and in the inside of the jaw slide seat, a chute 19 inclined relative to the upper surface of the jaw base is provided. There is a fixed jaw 14, and the driving rod 11 is rotatably connected to the outside of the jaw slide 15, and a second pin 18 is fixed on the sliding jaw 16, and the second pin 18 passes through the jaw slide and Stretch into the driving rod 11 and can slide in the driving rod. In the natural state, the sliding jaw 16 is closed on the fixed jaw 14 under the action of the gravity of the driving rod. The impact force causes the sliding jaw 16 to move upwards away from the fixed jaw 14 . In the present invention, the clamping mechanism 10 is used to fix the drawing pipes such as copper pipes, and...

Abstract

The invention relates to a clamp mechanism. The clamp mechanism comprises a clamping mechanism and a collision mechanism, wherein the clamping mechanism comprises a drawing rod, a jaw base and a jaw slide base, wherein the jaw slide base is fixed on the jaw base, and a slide rod which tilts relative to the upper surface of the jaw base is formed inside the jaw slide base; a slide jaw is formed inthe slide slot; a fixed jaw is fixedly arranged in the jaw base; the drawing rod can be rotatably connected to the outer side of the jaw slide base; a second pin is fixed on the slide jaw; the secondpin is arranged on the jaw slide base in a penetrating mode, extends into the drawing rod, and can slide in the drawing rod; and under action of gravity of the drawing rod, the slide jaw is closed onthe fixed jaw, and the collision mechanism can generate collision force on the drawing rod, so that the slide jaw moves upwards to be away from the fixed jaw. According to the clamp mechanism disclosed by the invention, the clamping mechanism and the collision mechanism are separately arranged, and a gas cylinder is not arranged on a rotary disc barrel, so that the main shaft structure and gas path layout are simplified, and fault points are reduced.

Description

technical field [0001] The invention relates to a clamp mechanism, in particular to a clamp mechanism and a coil drawing machine using the mechanism. Background technique [0002] In the production of precision seamless copper pipes, internal thread equipment, coil drawing machine equipment, etc. are very common to use the motor reducer to drive the coil to rotate as the power device for drawing production. At the beginning of copper tube drawing, the clamps are required to pull the copper tube until the pressure roller (wheel) presses the copper tube to build up sufficient friction. [0003] Such as Figure 10 The clamp mechanism shown is the most commonly used form at present, and its structure mainly includes a flange 1, a cylinder 2, a connecting piece 3, a moving pin 4, a set screw 5, a clamp block 6 and a jaw seat 7. The cylinder rod retracts, the clamp block moves backward, the jaws open, and the pipe head extends into the clamp block; the cylinder rod extends to cla...
