CN104043814A - Automatic cleaning batch seam sand burning technology for casting part main runner - Google Patents

Abstract

The invention belongs to the field of casting part sand removing processes, and discloses an automatic cleaning batch seam sand burning technology for a casting part main runner. According to the automatic cleaning batch seam sand burning technology for the casting part main runner, a runner cleaning tool is utilized, and the sand blasting and vibrating processes are combined. The technology comprises the following steps of conducting surface sand removing treatment, using the sand vibrating technology for shot blasting, cleaning arbors, punching a hole with an electric drill with the drill bit, chopping off the arbors with an iron chopper, clamping out the arbors with a clipper, removing main runner burrs, cleaning the bent runner arbors, blowing off one bent runner arbor with oxygen, removing black sand inside the runner, beating a casting part with an iron hammer, enabling the sand inside the runner to flow out through vibration, then conducting secondary sand vibration and shot blasting, and conducting endoscopy. The automatic cleaning batch seam sand burning technology has the advantages of being reasonable, convenient to operate, applicable to the casting part with the complex runner, good in sand removing effect and the like.

Description

Cast member sprue Automatic clearance is criticized seam scab technique

Technical field

A kind of cast member sprue Automatic clearance that the present invention relates to cast cleaning operation field is criticized seam scab technique.

Background technology

Casting field at present, the cleaning of core is the technological difficulties of casting industry, the cleaning of core directly has influence on the quality of foundry goods, about the cleaning of core, common method has quick-fried sand and the sand that shakes at present, and quick-fried sand is to adopt the heating that heats up, resin bed to core destroys, and reaches the object of cleaning core; The sand that shakes is under the vibration of certain frequency, destroy its bonding force, thereby its sand is dropped, to reach the object of sand removal, although quick-fried sand and the sand that shakes can be cleared up most of core, cannot clean out for the core in runner and the traditional quick-fried sand of the arbor sand technique of shaking.

Summary of the invention

The object of the invention is the deficiency existing for the core of the inner flow passage of intricate casting and arbor cleaning for current casting field, utilize runner cleaning tool to criticize seam scab technique in conjunction with the quick-fried sand a kind of cast member sprue Automatic clearance that sand operation proposes that shakes.

The present invention is achieved by the following technical solutions:

A kind of cast member sprue Automatic clearance is criticized seam scab technique, it is characterized in that: foundry goods sprue and batch seam scab processing comprise following operation:

1) surperficial sand removal processing: with the sand technique ball blast that shakes, be not less than 15 minutes at every turn, remove surperficial sand grains, the residual cast gate grains of sand are smooth with large grinder buffing, plane roughing 4-5mm on foundry goods;

2) cleaning arbor: with the punching of 8.5mm drill bit electric drill, cut arbor is chopped off with iron, arbor is chopped off from punching and poured out arbor one by one, with sharp-crested clamp knockout bone, cleaning sprue burr, takes out arbor;

3) curved runner arbor cleaning: blow a curved runner arbor off with oxygen;

4) black sand cleaning in runner: beat foundry goods with iron hammer, by vibration, the sand in runner is flowed out, use powerful sand spray machine sand spray after having beaten, sand residual in runner is removed, till spraying without black sand in hole, then carry out the secondary sand ball blast that shakes;

5) endoscopy.

The foundry goods of above-mentioned sand removal technique to inner flow passage complexity, particularly cannot take out by traditional quick-fried sand sand work technique of shaking the arbor in curved runner, punch by electric drill for the arbor in runner by electric drill and veneer clipper, cut arbor segmentation is chopped off with iron, then take out with veneer clipper.

The present invention compared with prior art has following beneficial effect:

1. technique is reasonable, easy to operate;

2. be suitable for runner intricate casting, sand removal is effective.

Detailed description of the invention

The quick-fried sand of a kind of use that the present invention be directed to the design invention of the runner intricate casting sand technique of shaking is removed the method for core and arbor in conjunction with electric drill and veneer clipper.

Foundry goods sprue and batch seam scab treatment process comprise the following steps:

Surface sand removal processing: with the sand technique ball blast that shakes, be not less than 15 minutes at every turn, remove surperficial sand grains, the residual cast gate grains of sand are smooth with large grinder buffing, plane roughing 4-5mm on foundry goods;

Cleaning arbor: with the punching of 8.5mm drill bit electric drill, cut arbor is chopped off with iron, arbor is chopped off from punching and poured out arbor one by one, with sharp-crested clamp knockout bone, cleaning sprue burr, takes out arbor;

Curved runner arbor cleaning: blow a curved runner arbor off with oxygen;

Black sand cleaning in runner: beat foundry goods with iron hammer, by vibration, the sand in runner is flowed out, use powerful sand spray machine sand spray after having beaten, sand residual in runner is removed, till spraying without black sand in hole, then carry out the secondary sand ball blast that shakes;

Endoscopy.
