Description

Apparatus and method for combining lock block

The present invention relates to an air conditioning cooling circuit, and more particularly, to an apparatus and method for coupling a lock block in a horizontal pressurization manner to an end of a connecting pipe of a high pressure hose through which a refrigerant of an air conditioner passes.

The cooling circuit, in particular the cooling circuit of an air conditioner used in a vehicle, consists of a compressor, a condenser, a dryer, an evaporator, and an expansion valve. An air conditioner hose is installed as a passage of the refrigerant gas between these components constituting the cooling circuit.

The air conditioner hose is divided into a suction hose and a discharge hose according to the pressure of the refrigerant gas. The low pressure hose is a passage of refrigerant gas having a relatively low pressure, and is generally used as a circulation passage of a refrigerant from an evaporator to a compressor in a vehicle cooling circuit. High pressure hoses, on the other hand, are passages of relatively high pressure refrigerant gas, and are generally used as circulation passages of refrigerant from the compressor to the condenser in the cooling circuit of a vehicle.

In general, the air conditioner hose is composed of a lock block (lock block), a connecting pipe, and a fixing member, of which the lock block is coupled to the components of the cooling circuit to which the air conditioner hose is connected to serve to fix the air conditioner hose.

As a method of coupling the lock block to the pipe of the air-conditioning hose, conventionally, a pipe is cut directly to form a coupling groove or a coupling protrusion, and then the lock block is fitted into the coupling groove or the coupling protrusion.

However, when using such a conventional method, the thickness of the cut part of the pipe may become thinner than the thickness of the uncut part, which may damage the pipe. In addition, the configuration of the device for cutting pipes is complicated and there are problems such as debris in the process of cutting pipes.

Therefore, a new way to join lock blocks without cutting pipes is needed.

The technical problem to be achieved by the present invention is to provide an apparatus for coupling the lock block to the end of the connection pipe of the high pressure hose through which the refrigerant of the air conditioner passes in a horizontal pressure manner.

Another technical problem to be achieved by the present invention is to provide a method of coupling the lock block to the end of the connecting pipe of the high pressure hose through which the refrigerant of the air conditioner passes in a horizontal pressure manner.

Lock block coupling apparatus according to an embodiment of the present invention for achieving the above technical problem includes a lock block feeding unit, and a lock block punching unit. The lock block feeding part buffers and provides the lock block using a slope. The lock block punching part fits the lock block to the end of the pipe by inserting the lock block into the end of the pipe and then punching the end of the pipe one or more times in the horizontal direction.

At this time, the lock block punching portion includes the first to third lock block punches. The first lock block punch inserts the provided lock block into the end of the pipe, and then punches the end of the pipe to form an escape preventing protrusion for preventing the detachment of the fixed block. A second lock block punch punches the end of the pipe to form the release preventing protrusion into blocking beads. The third lock block punch includes a third lock block punch to punch the end of the pipe to form a locking bead. The lock block is coupled to the end of the pipe in a manner secured between the blocking bead and the locking bead, and the lock block is provided to the first lock block punch while the third lock block punch performs punching. .

Meanwhile, the lock block punching unit may include a plurality of lock block punches, wherein the lock block coupling device further includes a punch control unit to control on / off of each of the plurality of lock block punches, and the pipe The end is punched by the lock block punches controlled to be on among the plurality of lock block punches.

According to another aspect of the present invention, there is provided a method of combining a lock block by buffering a lock block using a slope, and inserting the lock block into an end of a pipe, and then closing the end of the pipe. Coupling the lock block to the end of the pipe by punching one or more times in a horizontal direction.

At this time, the step of coupling, after inserting the provided lock block to the end of the pipe, punching the end of the pipe to form a separation preventing projection for preventing the separation of the fixed block, punching the end of the pipe Shaping the release preventing protrusion into blocking beads, and punching an end of the pipe to form a locking bead, wherein the lock block is fixed between the blocking bead and the locking bead. Coupled to the other end of the lock block is provided during the forming of the locking bead.

Meanwhile, in the joining step, an end of the pipe may be punched more than once with a plurality of lock block punches, wherein the lock block joining method controls on / off of each of the plurality of lock block punches. Further comprising a step, wherein the pipe end is punched by lock block punches controlled to be on among the plurality of lock block punches.

As described above, the lock block coupling device according to the present invention can prevent damage to the pipe by coupling the lock block to the pipe in a horizontal pressurizing manner without cutting the pipe, and simplify the process of coupling the lock block to the pipe. There are advantages to that.
