Description

Technical Field

[0001] This utility model relates to a tooling device capable of stamping insulating gaskets of different specifications. Background Technology

[0002] The amount of insulating gaskets used in transformer coils is very large. Each coil must be spaced apart with insulating gaskets, and a certain width of oil channel must be left between each coil to allow transformer oil to flow through the oil channel, which plays the role of insulation and heat dissipation.

[0003] Currently, most large transformer coil insulation gaskets are either slotted or dovetail shaped. In traditional insulation gasket processing, a set of stamping equipment is required for each size of insulation gasket. Some transformer products have a limited number of identical models manufactured, resulting in a set of stamping equipment being idle after producing one type of matching insulation gasket. This leads to very low utilization of the equipment and the need for regular maintenance, causing unnecessary waste. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tooling equipment that can stamp insulating gaskets of different specifications. It can solve the problem that currently, each size of insulating gasket requires a set of tooling equipment for stamping insulating gaskets, resulting in high equipment idle rate and unnecessary waste.

[0005] The purpose of this utility model is achieved as follows: a tooling device for stamping insulating gaskets of different specifications includes an upper die and a lower die; The lower die includes a lower concave die, which is fixed to the lower concave frame by pins. A gasket guide plate is bolted to the top of the lower concave die. The lower surface of the gasket guide plate has a continuous insulating gasket guide groove. The gasket guide plate has a hole that matches the size and shape of the upper punch (i.e., the tool for processing the insulating gasket). This hole is connected to the insulating gasket guide groove. The lower concave die below this hole has a through hole for discharging waste material. A baffle guide rail is connected to the gasket guide plate. The baffle guide rail is bolted to the front end of the gasket guide plate near the right edge. The baffle guide rail has an axial elongated hole. A gasket positioning baffle is slidably connected to the baffle guide rail. After the bolt of the gasket positioning baffle passes through the axial elongated hole from the top of the baffle guide rail, tightening the nut located below the gasket positioning baffle can limit the position of the gasket positioning baffle.

[0006] The upper mold includes an upper punch, which is installed at the bottom of the punch fixing plate. The shape of the front half of the upper punch is the same as the shape of the tail end of the insulating gasket, and the shape of the rear half of the upper punch is the same as the shape of the head end of the insulating gasket. The punch fixing plate is connected to the upper mold frame by bolts.

[0007] The punch fixing plate is also fixed with a downward extending ejector pin, which is located in front of the upper punch.

[0008] Finally, install the upper and lower dies onto their respective punch presses and calibrate them before use.

[0009] The advantages of this invention are: This device can produce insulating gaskets of different lengths by adjusting the baffle to the desired length according to the operating steps. It solves the problem that currently, each size of insulating gasket requires a separate stamping fixture, and for some transformer products with a small production run, a single stamping fixture can only produce one type of matching insulating gasket, leaving the fixture idle and resulting in low equipment utilization. Furthermore, regular maintenance of the stamping fixture leads to unnecessary waste. Attached Figure Description

Detailed Implementation

[0011] The following is combined Figure 1-4 The present invention will be further described below; A tooling device for stamping insulating gaskets of different specifications includes an upper die and a lower die; The lower mold includes a lower concave mold 2, which is fixed to the lower concave frame 1 by pins. A gasket guide plate 3 is bolted to the top of the lower concave mold. The lower surface of the gasket guide plate is provided with a continuous insulating gasket guide groove 10. The gasket guide plate is provided with a hole 11 that is adapted to the shape and specifications of the upper punch 6. The hole is connected to the insulating gasket guide groove. The lower concave mold below the hole is provided with a waste discharge through hole. A baffle guide rail 4 is connected to the gasket guide plate 3. The baffle guide rail is bolted to the front end of the gasket guide plate near the right edge. The baffle guide rail is provided with an axial elongated hole 12. A gasket positioning baffle 5 is slidably connected to the baffle guide rail. After the bolt of the gasket positioning baffle passes through the top of the axial elongated hole of the baffle guide rail, tightening the nut located below the gasket positioning baffle can realize the limitation of the gasket positioning baffle.

[0012] The upper mold includes an upper punch 6, which is installed at the bottom of the punch fixing plate 7. The shape of the front half of the upper punch is the same as the shape of the tail end of the insulating gasket, and the shape of the rear half of the upper punch is the same as the shape of the head end of the insulating gasket. The punch fixing plate is connected to the upper mold frame 9 by bolts.

[0013] The punch fixing plate is also fixed with a downward extending ejector pin 8, which is located in front of the upper punch; the ejector pin can gently knock the stamped insulating pad into the receiving box, preventing the pad from accumulating or splashing at the equipment outlet.

[0014] Finally, install the upper and lower dies onto their respective punch presses and calibrate them before use.

[0015] Working Process: Adjust the pad baffle to the designated position according to the required insulation pad length and tighten the nut to fix it. Then, feed the raw insulation paperboard from the rear end of the pad guide plate into the insulation pad guide groove, ensuring that the front end of the raw insulation paperboard contacts the pad baffle. Operate the punch press to make the upper die press downwards on the insulation paperboard in the insulation pad guide groove, dividing it into two insulation pads. This simultaneously forms the beginning and end of two adjacent insulation pads. Remove the front insulation pad and continue moving the raw insulation paperboard towards the pad baffle, ensuring that its beginning end contacts the pad baffle. The punch press operates again, making the upper die press downwards on the insulation paperboard in the guide plate groove, continuing to divide it into two insulation pads. The end of the front insulation pad is now processed. Repeat the above steps to continuously produce pads. This process is convenient, stable, fast, and produces good forming results. The cycle continues.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
