Description

A thread rolling machine with a separating device

technical field

The utility model relates to a thread rolling machine used for thread processing, in particular to a thread rolling machine with a separating device.

Background technique

The thread rolling machine is a special mechanical equipment for producing screws, screw fasteners and outer circumferential threads. The thread rolling machine is to use the parallel sliding of parallel tooth plates to form threads, which is a kind of cold extrusion processing. The thread rolling machine has various specifications, such as automatic thread rolling machine, flat plate thread rolling machine, semi-automatic thread rolling machine, automatic thread rolling machine, high-speed thread rolling machine, etc.

After the screw is threaded by the thread rolling machine, the surface of the screw coming out of the thread rolling machine contains a large amount of iron filings and cooling oil, which are directly collected into the storage box, making the surface of the screw difficult to clean, and the iron filings are easy to scratch the thread The surface affects the quality of the screw, and the cooling oil cannot be recycled in time, causing environmental pollution and waste.

Utility model content

The technical problem to be solved by the utility model is to provide a thread rolling machine with a separation device. This separation device realizes the separation of the iron filings and cooling oil from the screw after the screw is completed through the thread rolling process, so that the screw can be obtained This ensures more timely and convenient cleaning, avoids iron filings from scratching the screw surface, and the cooling oil is recycled and reused at the same time, which protects the environment and saves costs.

In order to solve the problems of the technologies described above, the technical solution adopted by the utility model is:

A thread rolling machine with a separating device, including a conveying device, a thread rolling device and a screw containing box, and also includes a separating device, the separating device is located between the thread rolling device and the screw containing box, and the separating device includes The conveying cylinder and the conveying worm, the conveying cylinder and the conveying worm are equal in length and diameter, they are installed in parallel, and there is a gap between them, the gap is large enough to allow the shank of the screw to enter, and the nut part of the screw Supported between the two; the pitch and tooth height of the thread on the conveying worm should correspond to the size of the screw, so that the screw can be inserted between the teeth of the conveying worm, and a power device for the separation device is provided.

Preferably, both the conveying cylinder and the conveying worm are driven by a power device, and both rotate in the same direction.

Preferably, the conveying worm is driven by a power device, and the conveying cylinder does not move.

As a preference, a cooling oil collection box is also installed below the separation device.

Preferably, a protective cover 4 fixedly connected to the frame is provided above the separating device to prevent the screw from falling into the space outside the separating device after thread rolling.

The beneficial effect produced by adopting the above technical scheme is: in the traditional thread rolling machine, after the screw is threaded by the thread rolling device, the surface of the screw coming out of the thread rolling device has a large amount of iron filings and cooling oil, which are directly collected into the container. In the box, it is difficult to clean the surface of the screw, and the iron filings are easy to scratch the thread surface, which affects the processing quality, and the cooling oil cannot be recycled in time, causing environmental pollution and waste. In this scheme, a separation device for iron filings and cooling oil is set between the thread rolling device and the screw holding box, so that after the screw has completed the thread rolling process, the iron filings and cooling oil are separated from the screw through the separation device. The surface of the screw is cleaned more timely and conveniently, and iron filings are prevented from scratching the surface of the screw, and the cooling oil is recycled and reused at the same time, which protects the environment and saves costs.

The names of each drawing number are: 1—conveying cylinder; 2—conveying worm; 3—screw; 4—protective cover.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the utility model includes a conveying device, a thread rolling device and a screw holding box, and also includes a separating device, the separating device is located between the thread rolling device and the screw holding box, and the separating device includes a conveying cylinder 1 and the conveying worm 2, the conveying cylinder 1 and the conveying worm 2 are equal in length and equal in diameter, the two are installed in parallel, and there is a gap between the two, the size of the gap can allow the shaft of the screw 3 to enter, and the screw 3 The nut part is supported between the two; the pitch and tooth height of the thread on the conveying worm 2 should correspond to the size of the screw 3, so that the screw 3 can be inserted between the teeth of the conveying worm 2, and set A power unit with a separation device. When working, the screw 3 is conveyed by the conveying device first, enters the thread rolling device to process the thread, and after the thread rolling is completed, enters the separation device, the screw 3 enters the gap between the conveying cylinder 1 and the conveying worm 2, passes through the conveying cylinder 1 and the conveying worm 2 in the opposite direction, so that the screw moves forward along the axial direction of the two. At the same time, during the movement, the iron filings and cooling oil attached to the surface of the screw will flow from the gap between the conveying cylinder 1 and the conveying worm 2. Falling, so as to achieve the separation of iron filings and cooling oil, and the collected cooling oil can also be reused to save production costs. After passing through the separation device, the cleaned screws can be collected into the screw holding box.

Further, both the conveying cylinder 1 and the conveying worm 2 are driven by the power device, and both rotate in the same direction, which can reduce the friction force, or the conveying worm 2 is driven by the power device, and the conveying cylinder 1 does not move, so that the power device can be reduced and the energy consumption; there is also a cooling oil collection box under the separation device, which can more conveniently collect the cooling oil falling from the screw, achieve the recovery of the cooling oil for secondary use, and save energy; and can be fixed above the separation device The protective cover 4 connected on the frame prevents the screw 3 from falling into the space outside the separation device after thread rolling, and scatters into the ground or the machine, causing difficulties in collection or damage to the machine, saving labor and ensuring continuous work.
