Description

Integral suspension type in-mold tapping device

technical field

The present invention relates to a tapping device, in particular to an integrally suspended in-mold tapping device.

Background technique

The in-mold tapping device is also called the in-mold tapping device. It is a device that cooperates with the metal continuous mold to quickly process the screw holes during the stamping process of the hardware parts.

The in-mold tapping device "integrates" the traditional "stamping" and "tapping" technologies together to form directly in the mold. The in-mold tapping device uses extrusion taps for tapping, so there will be no chips formed by cutting during the thread forming process, which is clean and environmentally friendly, and the strength of the thread has been greatly improved. These are incomparable to traditional craft processing. Because the in-mold tapping machine has the above-mentioned characteristics, the in-mold tapping machine is widely used.

The traditional in-mold tapping machine is a fixed design. Specifically, the main body of the in-mold tapping device is installed on the lower mold plate or the discharge plate of the mold, and the transmission screw part is fixed on the upper plate. Within a certain stamping stroke space, Extruded by the downward movement of the punch slider, the lower tap moves down and rotates to tap the material, and then the punch slider moves upward to drive the tap to reverse movement and reverse rotation, and returns from the tooth hole to complete the whole process. Tapping process.

The traditional die tapping machine, because of the limited installation and working methods, all its power comes from the punch, which can only be designed for fixed connection, which occupies a large part of the stamping stroke space, making the feeding space small, such as using traditional manual During the feeding operation, it will not affect the feeding and discharging, but if the mechanical automatic feeding method is used, when the multi-dimensional feeding manipulator is used, it will bring great inconvenience to the feeding of the automatic feeding mechanism, and it will be fixed in the mold during the stamping stroke. The tapping machine is easy to come into contact with the automatic feeding mechanism or the material itself, which affects the normal operation of the tapping mechanism.

Contents of the invention

The purpose of the present invention is to provide an integral suspension type in-mold tapping device that is suitable for cooperating with the automatic feeding mechanism and can move up and down with the stamping to maximize the feeding space.

In order to achieve the above object, the present invention is achieved through the following technical means.

The overall suspension type in-mold tapping device of the present invention includes an upper backing plate, a lower backing plate, a transmission screw, a transmission cup, a tapping mechanism, and a transmission mechanism.

A transmission screw rod is also fixedly installed on the upper backing plate.

A plurality of springs are also connected and installed between the upper backing plate and the lower backing plate. the

As a preference, the spring is a nitrogen gas spring.

A plurality of positioning guide posts are arranged on the lower surface of the lower backing plate.

The lower backing plate is also rotatably installed with a transmission cup corresponding to the transmission screw.

The drive cup is covered with a driving gear.

The tapping mechanism is fixedly installed on the lower backing plate.

 The tapping mechanism includes a housing, a tap, a floating plate, a driven gear and a screw.

The driven gear is fixedly installed in the housing and can freely rotate along its axis.

Threads are provided on the inner wall of the shaft center hole of the driven gear.

The tail of the screw tap is connected and matched with a screw rod inserted into the shaft center hole of the driven gear.

The floating plate is installed on the lower surface of the shell, and is connected and matched with the shell through a guide post equipped with a spring.

A tap hole corresponding to the position of the tap is provided on the floating plate.

The driving gear and the driven gear are driven and matched through the transmission mechanism installed on the lower backing plate.

The transmission mechanism is composed of multiple gears meshing with each other.

During the work of the present invention, it is integrally fixed on the upper mold base of the mold installed on the punching machine, and is used to cooperate with the stamping product to be moved by manual transfer or other automatic feeding mechanism to carry out the thread forming of the product. Drive down, run until the lower backing plate is in contact with the lower support plate on the lower stamping equipment workbench, start to compress the nitrogen spring, and push the transmission screw, the transmission cup converts the vertical downward movement of the transmission screw into the rotation of the transmission cup , The driving gear on the transmission cup rotates synchronously with the transmission cup, and the driven gear is driven to rotate through the transmission mechanism, and then the driven gear rotates through the screw conversion to drive the rotation and up and down movement of the tap. When the upper mold base goes down to the lowest point, the tapping action is completed and the reset begins. The nitrogen spring on the present invention resets and pushes the lower backing plate to reset, so that the transmission cup reverses, thereby driving the tap to rotate in the opposite direction and retreat. Realize the retraction action.

Compared with the traditional technology, the present invention has the positive effect that the tapping device and the punching machine move up and down synchronously, and when processing, a larger stroke space is reserved for the automatic feeding mechanism, which is convenient for automatic production and processing.
