Pressing device for steel casting machining

Abstract

The invention discloses a pressing device for steel casting machining. The pressing device comprises a first shell, two second shells and third shells; square through holes are formed in two sides ofthe first shell; a placing table is fixedly mounted at the bottom of the first shell; the second shells and the third shells are positioned in the first shell; the third shells are positioned on the two second shells; a limiting block comprises a long main plate; bosses are symmetrically arranged on two sides of the main plate, and are provided with multiple positioning holes; the distances from the circle centers of the positioning holes to the circle center of the long main plate are the same; and the positioning holes cooperate with clamping plates. Plates for production of steel safety doors are placed in the first shell, and meanwhile, are fixed in the first shell; and the parts needing to be polished or trimmed are machined at the external of the first shell, so that the stability and the tidiness of the plates in the machining process are effectively guaranteed, and the product pass percent and the production efficiency are effectively improved.

Description

technical field [0001] The invention relates to the technical field of compression, in particular to a compression device for processing steel castings. Background technique [0002] The full name of anti-theft door is "anti-theft safety door". It has both anti-theft and safety performance. According to the "General Technical Conditions for Anti-theft Safety Doors", a qualified anti-theft door cannot be pried open by ordinary hand tools such as chisels, screwdrivers, crowbars, and portable electric tools such as electric hand drills within 15 minutes or a 615 square millimeter hole can be opened on the door leaf. opening, or a 38 mm2 opening within a semicircle of 150 mm2 at the locking point. And the lock used on the security door must be the special lock for the security door with anti-drilling function after passing the test by the Testing Center of the Ministry of Public Security. Anti-theft doors can be made of different materials, but only those doors that have pass...

Problems solved by technology

[0003] During the processing and production of steel anti-theft doors, it is necessary to trim and polish the periphery of the door. However, during the trimming and polishing process, the anti-theft door is prone to slipping, which makes the grinding uneven. During the grinding process, all kinds of dust and debris will adhere to the surface of the door body. Before the next step, the surface needs to be wiped manually, which not only affects the processing quality of the security door, but also makes the processing process time-consuming and labor-intensive. For this reason, we propose a pressing device for steel casting processing
