Description

A lateral moving device for cold heading machine clamps

Technical field

The invention relates to the technical field of cold heading machine manufacturing, and specifically relates to a lateral moving device for cold heading machine clamps, which is used to improve the performance of the cold heading machine.

Background technique

The cold heading machine is a production equipment with a high degree of automation, among which the multi-station cold heading machine is the mainstream. It uses multiple consecutive extrusions to extrude metal into the required shape. Starting from raw materials, the metal enters the inside of the die one by one, and turns into semi-finished products at the first station, then semi-finished products at the second station, until it becomes the final finished product. In order to realize the movement of metal between the upper and lower work stations, clamps are needed to undertake this work.

Clamps are a set of mechanical devices that can perform opening and closing actions. There are pure mechanical structures and electronic servo-driven ones. Each work station, including the cutting station, is equipped with a clamp. All the clamps on the machine form a clamp group and can move laterally. Its working process:

A. The clamp group moves to the position of the previous station;

B. Each clamp is in an open state;

C. The formed semi-finished product is ejected from the mold or scissor plate and enters the clamp of the corresponding station;

D. Each clamp is closed according to the set time to tightly clamp the formed semi-finished product;

E. All clamps act as a clamp group and move laterally to the next station together;

All clamps are opened one by one according to the set time, and the punch of the cold heading machine pushes the semi-finished product into the mold of the next station.

The problems existing in the existing technology are:

In the actual production process, sometimes there are pits or protrusions on the end face of semi-finished parts, and the corresponding protrusions or pits are designed on the front end face of the ejector rod of the die. In this case, if the clamp group simply moves laterally to the next station, there will still be mechanical interference between the ejector rod of the die and the semi-finished part. The protruding part of the ejector rod of the die blocks the lateral movement of the semi-finished part. , which will cause the semi-finished parts to fly out and fall or be offset and skewed, causing the transfer process to fail, as shown in Figure 6.

From a bird's-eye view, the movement trajectory of the clamp group of the current mainstream cold heading machine is shown in Figure 7: The clamp group of some models adopts an A-type trajectory for lateral movement, that is, when the clamp group moves laterally, there is a slight movement. In a certain arc, near the center of the running trajectory, the clamp group moves 5-10 mm along the plane away from the equipment mold.

There are also many models where the clamp group moves laterally using a B-type trajectory, that is, when the clamp group moves laterally, it always moves along a straight line. The distance between the clamp set and the machine mold plane is always fixed.

The above two moving trajectories A and B cannot meet the needs of producing products with protrusions or pits on the end surface.

In view of this situation, the actual cold heading production site urgently needs a safe and reliable equipment to solve such problems.
