Description

Floated paint film forming die

Technical Field

The utility model relates to a forming die of enameled wire, especially a floated film forming die.

Background

Before entering an enamelling furnace, the enamelled wire after painting needs to be subjected to a paint film forming process, so that the thickness and the roundness of a paint layer on the surface of the enamelled wire can reach specified standards. The traditional paint film forming process is that an enameled wire passes through felts which are mutually jointed, and redundant paint on the surface of the enameled wire is wiped off by utilizing the joint surface of the felts; however, the forming mode is difficult to control the size of the paint film, and the enameled wire can leave obvious creases on the position of the binding face in the continuous wiring process, so that the felt cannot completely wipe the paint film at the crease positions.

In order to solve the problems, the conventional paint film forming method for the enameled wire is to arrange a fixed forming die on an enamelling machine, and the enameled wire passes through an inner hole of the forming die, so that a paint film can form an outer circle with the same diameter as the inner hole after passing through the inner hole of the die, and the forming precision of the paint film is effectively improved. However, the enameled wire can float up and down along with the equipment during routing, so that the enameled wire can often pass through a forming die at an inclined angle during film forming, bending and surface indentation of the enameled wire are caused, the processing quality of the enameled wire is affected, and the wire breaking risk exists. In addition, in order to ensure the forming quality of the enameled wire, the process has higher requirements on the position precision of a forming die; therefore, the processing precision and the positioning precision of the forming die need to be correspondingly improved, and the production and use cost of the forming die is increased. Therefore, the existing paint film forming die for the enameled wire has the problems that the enameled wire is easy to damage and the production cost is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a floated film forming die. The enameled wire has the characteristics of difficult damage and low production cost.

The technical scheme of the utility model: the utility model provides a floated paint film forming die, is equipped with a plurality of suspension grooves including the rack that is located the enamelling machine front end on the rack, and the suspension groove is including standing groove and the trough that communicate each other, and the tip of standing groove and trough communicates with the outside respectively, is equipped with the design mold core of over-and-under type in the standing groove, and design mold core inboard is equipped with the one-tenth die cavity that is used for walking the line.

In the suspended paint film forming die, the forming cavity is conical, and the conical angle of the forming cavity is 10-35 degrees.

In the suspension paint film forming die, the upper surface of the suspension groove is communicated with the outside, and a gap is reserved between the bottom surface of the suspension groove and the bottom surface of the placing frame.

In the suspended paint film forming die, the lower end of the placing frame is detachably connected to an enamelling machine between the painting roller and the oven.

In the suspension paint film forming die, the placing frames are arranged on the enamelling machine in a multi-row staggered mode.

Compared with the prior art, the utility model has the advantages that the suspension groove and the shaping mold core are matched, so that the shaping mold core can be matched with the enameled wire to freely lift in the suspension groove when working, thereby ensuring that the enameled wire can be in a linear state when passing through the shaping mold core, effectively avoiding the bending or indentation phenomenon of the enameled wire and improving the forming stability of a paint film; the shaping mold core does not need to be positioned, and the height position of the shaping mold core can be mutually adaptive to the enameled wire, so that the shaping mold core can remove a fixed structure of the shaping mold core, the processing cost and the precision requirement on the shaping mold core are reduced, the reduction of the shaping effect caused by positioning deviation is avoided, and the shaping stability of the enameled wire is further improved; through the structural optimization of the forming cavity, the forming effect on the paint film can be guaranteed, and the damage of the paint film caused by overlarge angle when the forming cavity extrudes the paint film is prevented.

Furthermore, the utility model discloses a be multirow dislocation set with the rack, make and to leave the interval between each rack to the convenience is to the installation of rack and the regulation on the transverse position, and then improves the shaping effect of design mold core. Therefore, the utility model has the characteristics of the enameled wire is difficult damaged, low in production cost.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. The utility model provides a floated paint film forming die, constitutes as shown in figure 1, including the rack 1 that is located the enamelling machine front end, is equipped with a plurality of vertical suspension grooves on the rack 1, and the suspension groove is including standing groove 2 and the trough 3 of mutual intercommunication, and the tip of standing groove 2 and trough 3 communicates with the outside respectively, is equipped with the design mold core 4 of over-and-under type in the standing groove 2, and design mold core 4 inboard is equipped with the shaping chamber 5 that is used for walking the line.

The shape of the forming cavity 5 is conical, and the conical angle of the forming cavity 5 is 10-35 degrees.

The upper surface of suspension groove and outside intercommunication leave the interval between the bottom surface of suspension groove and the bottom surface of rack 1.

The lower end of the placing rack 1 is detachably connected to an enamelling machine between an enamelling roller and a baking oven.

Rack 1 is the multirow dislocation set on the enamelling machine, and a plurality of rack 1 are a plurality of horizontal rows along walking the line direction and set up respectively on the enamelling machine promptly, leave the interval between the rack 1 of every horizontal row, and the mutual dislocation set between the rack 1 of different horizontal rows corresponds the enameled wire that should the region respectively.

The utility model discloses a theory of operation: the utility model discloses when using, install rack 1 in proper order in the stokehold position of enameling machine earlier to make every design mold core 4 that suspends the inslot pass respectively and correspond an enameled wire. After the placing frame 1 is fixed, the shaping mold core 4 is placed in the placing groove 2, and then the enameled wire sequentially passes through the forming cavity 5 and the wiring groove 3 to enter the enameled furnace, so that the excircle of a paint film on the surface of the enameled wire is gradually reduced along with the inner diameter of the forming cavity 5, and redundant insulating paint on the surface of the enameled wire is removed; meanwhile, the paint liquid forms extrusion force in the forming cavity, so that the forming mold core is kept in a suspension state and freely ascends and descends along with the enameled wire in the processing process, the problem of bending of the enameled wire or damage of the paint film due to friction is avoided, and the forming effect of the paint film is effectively improved.
