Abstract

The utility model relates to a capacitor coil pre-flattening device comprising a working cylinder, an upper die, a lower die and a frame, wherein the lower die is fixed on the frame, the upper die is fixed above the lower die through the working cylinder and capable of moving up and down along with the working cylinder, and the upper die and the lower die are equipped with electric heaters and temperature sensors. The capacitor coil pre-flattening device applies pressure and heat to the reeled coils through the upper die and lower die which are provided with the heaters to realize shaping the coils, and enables the coils not to deform when sent into a flattening machine, thereby reducing defective and waste products and increasing the rate of qualified product.

Description

Capacitor volume core precompressed flat package is put

Technical field

The utility model relates to a kind of capacitor process equipment, and specifically a kind of capacitor volume core precompressed flat package is put

Background technology

At present in process of production at high-power flat capacitor such as cbb61 type capacitor, need manually the volume core of winding is pinched flat put into flatting mill again and flatten setting after, just can put into the shell of moulding of flat.Yet, manual the volume core pinched flat operation not only waste time and energy, labour intensity is big, and because operating personnel's human factor and volume core circulate after spooling easy deformation in the process of flattening process, cause volume core waster more, production cost is higher.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art part, provides a kind of capacitor volume core precompressed flat package to put, and the volume core of winding is flattened typing in advance, makes when sending into flatting mill indeformablely, can reduce volume core time waste product, improves product percent of pass.

The technical solution adopted in the utility model is: it comprises working cylinder, upper die and lower die and frame, counterdie is fixed on the frame, patrix is fixed on the counterdie top by working cylinder and can moves up and down with working cylinder, and electric heater unit and temperature sensor are housed on the upper and lower mould.During work, the volume core of winding is placed on the counterdie, working cylinder drives the descending matched moulds of patrix, will roll up the core compression, and the upper and lower mould through heating adds thermal finalization to rolling up core simultaneously.

Priority scheme of the present utility model is: it also comprises a discharge cylinder, described discharge cylinder is located on the frame of counterdie one side, the piston rod of discharge cylinder is and is horizontally disposed with, and piston rod can be passed a station with the volume of the capacitor on counterdie core at least to the range of counterdie one side shifting.

Because the volume core is subjected to thermal finalization to need a period of time, the utility model scheme more preferably is: the length of upper and lower mould on the discharge cylinder piston rod is axial can be held two capacitors volume cores at least.Pass to counterdie one side station by the discharge cylinder piston rod behind the volume core pressurized and continue heating, can prolong volume core heated time on counterdie like this, can shorten upper and lower mould matched moulds pressing time, improve the operating efficiency of this device.

The utility model pressurizes to the volume core of spooling by the upper and lower mould of being with heater and adds thermal finalization, and is indeformable when feasible volume core is sent into flatting mill, can reduce the inferior waste product of volume core, the raising product percent of pass.

Embodiment

As shown in Figure 1, the utility model is made up of working cylinder 3, discharge cylinder 1, patrix 4, counterdie 9 and frame 11, counterdie 9 is fixed on the frame 11, patrix 4 is fixed on counterdie 4 tops by working cylinder 3 and can moves up and down with working cylinder 3, be fixed with guide post 12 on the patrix 4, frame 11 is provided with the pilot hole that cooperates with guide post 12, and

heating wire

5,10 and thermocouple 6,8 are housed on the upper and lower mould 4,9.Discharge cylinder 1 is located on the frame 11 of counterdie 9 one sides, and the piston rod of discharge cylinder 1 is and is horizontally disposed with, and piston rod can be passed a station as shown in Figure 3 with the volume of the capacitor behind the pre-setting on counterdie core 7 to the range of counterdie 9 one side shiftings.The length of upper and lower mould on the discharge cylinder piston rod is axial can be held four capacitors volume cores in this example.

During work, as shown in Figure 1, the volume core 2 of winding is placed on the counterdie 9; Then, sensitive switch (among the figure draw in the end) action when starting working cylinder 3 and driving patrixes 4 and go downwards to desired location on the frame 11, working cylinder stops action, and as shown in Figure 2, upper and

lower mould

4,9 matched moulds will roll ups that core compresses and to its heating; After the certain hour heating, working cylinder 3 drives patrix 4 up returning, and this moment, 1 work of discharge cylinder was passed a station to the right with the volume core behind the pre-setting, and as shown in Figure 3, the 4th volume core 7 of counterdie 9 right-hand members is pushed out; Discharge cylinder 1 resets then, and as shown in Figure 4, material loading carries out next circulation again.Because volume core residence time on counterdie is long, be heated fully, pre-setting is effective, and the upper and lower mould matched moulds time can shorten the working (machining) efficiency height simultaneously.
