Description

Split quenching spring support

Technical Field

The invention belongs to the field of heat treatment, and relates to a projectile body quenching process of a stepping heat treatment production line by using a split quenching projectile holder.

Background

The projectile body is a revolving body workpiece with an opening at one end, and the stepping production line is adopted for heat treatment production. During quenching, the projectile body is sent into the transfer mechanism bullet support by the quenching discharging machine, and the projectile body oral area is in the quenching oil in the oil groove along with the bullet support entering downwards, for the quenching effect of guaranteeing the projectile body, is equipped with at quenching oil tank bottom portion and spouts the mechanism of quenching, installs under the station that the bullet support corresponds promptly and spouts the quenching pipe. The quenching and cooling operation is completed by the rising and falling of the projectile body along with the projectile support. The quenching bullet holds in the palm the welding on the lifter plate, and the lifter plate is fixed on transfer mechanism with four bolts, and production process because of the projectile type difference, need change different bullet holds in the palm according to the different bores of projectile during the time of the conversion.

The size of the quench oil groove is

When the quenching bullet support is replaced, in order to ensure safety, quenching oil in the quenching oil groove needs to be completely placed, and the safety ladder is stepped for replacement, so that the working strength is increased, and the working efficiency is reduced.

Disclosure of Invention

In order to solve the problems of high working strength and long replacement time of replacing the bullet holder, a split quenching bullet holder is designed, namely, a fixed quenching bullet holder and a lifting plate are welded into a whole, the lifting plate is fixed on a transfer mechanism by four bolts, and a movable quenching bullet holder is manufactured according to the overall dimension of a bullet body. In the production process, because the types of the bullets are different, the quenching bullet holders do not need to be replaced and adjusted and fixed during the process of changing the production, and only different movable bullet holders need to be replaced according to different calibers of the bullets.

The invention is realized by the following technical scheme: the split quenching bullet holder is characterized by consisting of a fixed bullet holder and a movable bullet holder; the fixed bullet support is in an L shape, and the lower end of the fixed bullet support is provided with a circular ring with a stepped hole; welding a triangular reinforcing rib plate at the L-shaped right-angle position of the fixed bullet support; the movable bullet support consists of an upper end outer edge, a bullet support bottom with holes at the bottom end, and a plurality of uniformly distributed connection rib plates for connecting the bullet support and the outer edge; the height of the outer edge of the upper end of the movable bullet support is the same as the depth of a stepped hole in the upper end of the fixed bullet support, and the diameter of the outer edge of the upper end of the movable bullet support is smaller than the inner diameter of the upper end of the stepped hole in the fixed bullet support.

Furthermore, threaded holes are uniformly distributed in the side wall of a stepped hole at the upper end of the fixed bullet support, blind holes are uniformly distributed at the same position on the outer edge of the upper end of the movable bullet support, and then the fixed bullet support and the movable bullet support are fixed by screws, so that the fixed bullet support and the movable bullet support are integrated.

Further, the number of the threaded holes and the blind holes is 3.

Further, the movable bullet support is designed according to the characteristics of the overall dimension of the bullet body, and the movable bullet support is replaced according to the product type, namely the appearance of the bullet body.

Furthermore, the fixed elastic support is welded with the lifting plate to form a whole, and is fixed on the transfer mechanism by four bolts.

Furthermore, a triangular reinforcing rib plate is welded at the right-angle position between two sides of the L-shaped fixed elastic support.

Further, the device comprises 8 connecting rib plates for connecting the outer edge of the upper end and the elastic support of the lower end.

The invention has the beneficial effects that:

the invention has novel design, convenient installation, simple operation and safety. The requirement of fast changing production is met, the labor intensity of replacing the cartridge holder is reduced, the production efficiency is improved, and the product quality is guaranteed.

Detailed Description

The invention relates to a split quenching bullet holder, which consists of a fixed bullet holder and a movable bullet holder.

Wherein the fixed bullet holds in the palm 3 and becomes "L" type, and the upper end forms an organic whole with the lifter plate welding, fixes on transfer mechanism with four bolts, and fixed bullet holds in the palm the lower extreme and is the ring that the hole processed into the shoulder hole. In order to increase the strength of the fixed bullet support and prolong the service life, a triangular reinforcing rib plate is welded at the L-shaped right-angle position of the fixed bullet support.

The movable bullet support 4 is replaceable and has different shapes designed according to the external dimension characteristics of the bullet body, and consists of an upper end outer edge 6, a bottom end bullet support bottom with holes and 8 evenly distributed connecting rib plates 7 which are connected with the upper end and the lower end of the bullet support.

The height of the outer edge of the upper end of the movable bullet support is the same as the depth of the stepped hole at the upper end of the fixed bullet support, and the diameter of the outer edge of the upper end of the movable bullet support is slightly smaller than the inner diameter of the stepped hole at the upper end of the fixed bullet support. For preventing that the projectile body from getting into and taking out the time fixed bullet holds in the palm and removes the bullet and hold in the palm the emergence separation, hold in the palm 3 screw holes of upper end shoulder hole lateral wall equipartition at fixed bullet, hold in the palm 3 blind holes of the outer identical position equipartition of edge of upper end at the removal bullet simultaneously, then hold in the palm with the fixed bullet of screw fixation and remove the bullet and hold in the palm, make fixed bullet hold in the palm and remove the bullet and hold in the palm and become an organic whole.

The working process of the invention is as follows:

the fixed quenching bullet holder 3 and the lifting plate are welded into a whole, the lifting plate is fixed on the transfer mechanism by four bolts, and an inner hole at the upper end of the fixed bullet holder is processed into a stepped hole 4; the movable bullet holds in the palm 5 and designs according to body overall dimension characteristics, and the outer edge 6 height of the upper end of the movable bullet holds in the palm is the same with the 4 degree of depth of fixed bullet support upper end shoulder hole, and the diameter slightly is less than fixed bullet support upper end shoulder hole 4 internal diameter. For preventing that the projectile body from getting into and taking out the time fixed bullet holds in the palm 3 and removes 5 emergence separations of bullet support, hold in the palm 3 screw holes of 4 lateral walls equipartitions of upper end shoulder hole at fixed bullet, hold in the palm 3 blind holes of 6 same position equipartitions in the removal bullet simultaneously, then hold in the palm 3 and remove bullet support 5 with the fixed bullet of screw, make fixed bullet hold in the palm 3 and remove bullet support 5 and become an organic whole.

In the production process, when a product changes, the height of the fixed bullet support 3 does not need to be disassembled and adjusted, the movable bullet support 5 only needs to be replaced according to the product type, namely, the loose screws are taken out to move the bullet support 5, the new product needs to be replaced by the movable bullet support 5 and then the screws are fastened, and the bullet support replacement is completed. This has shortened the time of changing the bullet support greatly, has improved production efficiency, has reduced the machine that changes the bullet support and has repaiied personnel's intensity of labour.
