Description

A kind of seal cutter sweep

Technical field

The utility model relates to a kind of seal cutter sweep, and particularly a kind of seal that is used to intercept certain-length is produced the seal cutter sweep of sealing ring.

Background technology

Sealing ring is commonly employed at machinery, hydraulic pressure, pneumatic industry, be mainly used to prevent that working media from leaking or preventing introduced contaminants access arrangement inside from machine, its material is generally rubber, it is shaped as the annulus of sectional area for circular (or rectangle, Y shape, U-shaped etc.), mainly by the mould press forming.

In order to satisfy the demand of various parts, factory need lay in the sealing ring of all size, size.And in order to reduce the quantity in stock of sealing ring, cut the waste, improving capital turnover, sealing strip arises at the historic moment.The sectional area shape of sealing strip is the same with sealing ring, and circle, rectangle etc. are arranged, but it is not the annulus of sealing, but the bar of ten meters of radicals.In use, select the sealing strip of different cross section as required, intercept the sealing strip of respective length then, the two ends of sealing strip with intercepting are bonded as circular rings by glue again, produce sealing ring.

When maintenance activity, also can run into the sealing ring that does not promptly have required specification, there is not the situation of corresponding sealing strip yet.Generally can adopt in this case and select one or two sealing rings that sectional area is identical, then by cutting, bondingly produce required sealing ring.

No matter be to intercept on sealing strip or sealing ring is cut, it all has identical requirement to the seal of cutting.Fig. 1 is the seal schematic diagram of well cutting, and as shown in Figure 1, two of seal 100 are used for bonding cross section 101,102 must be smooth smooth; The sectional area equal and opposite in direction in two cross sections 101,102; The parallel identical cutting angle that promptly has is wanted in the cross section in two cross sections 101,102.

Existing cutting method to seal is that operating personnel hold seal with hand basically, two cross sections are cut respectively, be difficult to like this guarantee that two cross sections have identical cutting angle, the size in two cross sections is often also unequal, and since fixing seals well cause in the cutting process, the seal that is cut slides, thereby make the cut surface out-of-flatness, therefore, make that the bonding sealing ring of producing is undesirable.

Summary of the invention

For addressing the above problem, the utility model provides a kind of seal cutter sweep, cuts simultaneously by two cross sections to the required cutting of seal, guarantee that cut surface is smooth, and two cross sections has identical cutting angle.

For achieving the above object, seal cutter sweep of the present utility model comprises a handle, a knife rest, two blades, a base and two seal holddown grooves, and an end of described handle and described knife rest is by being threaded; The other end of described knife rest is connected by bearing pin with an end of described base, and knife rest can rotate around bearing pin; Described two blades are parallel to each other, and are fixed on the described knife rest by screw; Described two seal holddown grooves are fixed on the described base by screw, and two seal holddown grooves lay respectively at the both sides of two blades.

On the described base rubber blanket is arranged, described rubber blanket is positioned at the below of described two blades, and the width of described rubber blanket is greater than the spacing of two blades.

Seal cutter sweep of the present utility model has good stability in cutting process, can cut two cross sections of seal simultaneously, and the plane of being cut is smooth smooth, and two planes of being cut are parallel to each other.Seal cutter sweep of the present utility model is applicable to the seal of different cross section shape.

The specific embodiment

Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 2 is the schematic diagram of seal cutter sweep of the present utility model, and Fig. 3 is the schematic top plan view of seal cutter sweep among Fig. 2.As shown in the figure, seal cutter sweep of the present utility model comprises a handle 10, knife rest 20, two blades 30, base 40, two seal holddown grooves 50, and an end of handle 10 and knife rest 20 is by being threaded; The other end of knife rest 20 is connected by bearing pin 24 with an end of base 40, and knife rest 20 can rotate around bearing pin 24; Two blades 30 are parallel to each other, and are fixed on the knife rest 20 by screw 23; Two seal holddown grooves 50 are fixed on the base 40 by screw 45, and two seal holddown grooves 50 lay respectively at the both sides of two blades 30.

On base 40, be provided with rubber blanket 60, its be positioned at two blades 30 under.The width of rubber blanket 60 is greater than the spacing of two blades 30, and mainly being provides a support during for the cutting sealing part, and simultaneously because rubber is softer, blade that can blade 30 provides a better protect.

The length direction of seal holddown groove 50 and blade 30 make seal when cutting at an angle, and the cut surface of seal has bigger area.

Fig. 4 is the schematic diagram of Fig. 2 intermediate slide, and wherein (a) is the front view of knife rest, (b) is the left view of knife rest, and as shown in the figure, knife rest 20 is provided with a plurality of screw holes 230, is used for fixing blade 30, also is useful on the groove 21 that blade 30 is installed on the knife rest 20.Two blades 30 are installed on knife rest 20 simultaneously, cutting twice is converted into once cutting, can guarantee that like this movement locus of cutting twice keeps identical; The groove 21 that is used to blade 30 is installed can be guaranteed the parallel of two blades 30 by machine tooling acquisition better parallel degree.

One end of knife rest 20 has screwed hole 12, is used for fixing handle 10; The other end of knife rest 20 has pin shaft hole 240, is used for and being connected of base 40.

Fig. 5 is the schematic diagram of base among Fig. 2, and wherein (a) is the front view of base, (b) is the vertical view of base.As shown in the figure, can offer the two ends that 42, two the seal holddown grooves 50 of groove that are used to install seal holddown groove 50 place groove 42 respectively on the base 40, the groove 42 other screw holes 450 that are used for fixing seal holddown groove 50 that are provided with.Also can offer the rubber blanket mounting groove 41 that is used to place rubber blanket 60 on the base 40.

Fig. 6 is the schematic diagram of seal holddown groove among Fig. 2, and wherein (a) is the front view of seal holddown groove, (b) is the vertical view of seal holddown groove.The external form of seal holddown groove 50 is the U type, and the breach 52 of one end is to dodge blade 30 after being installed on the base 40, with groove 42 couplings among Fig. 5.The big I of seal holddown groove 50 is selected according to the size of seal and the shape of different sealing spare, makes the width of the sectional dimension of seal greater than seal holddown groove 50 upper grooves 51.Also can be according to the shape of different sealing spare since the size in seal cross section greater than the width of groove 51, after seal is installed in groove 51 on the seal holddown groove 50, rely on itself intrinsic elasticity fix.

When seal cutter sweep of the present utility model cuts seal, only need needs cutting sealing part is fixed in two seal holddown grooves 50, depress handle 10, just can cut simultaneously two cross sections of seal, the plane of being cut is smooth smooth, and two planes of being cut are parallel to each other.
