Abstract
The invention discloses a device for locking the jacking state of a maintaining furnace. The device is mainly composed of a rack, a walking locking block horizontal adjusting device, a locking oil cylinder, a walking locking block, a proximity switch and the maintaining furnace. The locking oil cylinder and the walking locking block are arranged on the rack, and the walking locking block is driven by the locking oil cylinder to move. The position of the walking locking block is detected by the proximity switch. The position and angle of the walking locking block can be finely adjusted by the walking locking block horizontal adjusting device in the horizontal direction. A locking adjusting block is arranged on the maintaining furnace through a rear bearing plate. Self-locking angles are arranged on the contact faces of the walking locking block and the locking adjusting block. The requirement for safety production of the maintaining furnace of an aluminum wheel hub air injection machine can be met, the safety coefficient is greatly improved, and in addition, the device has the beneficial effects of being simple in structure, low in manufacturing cost, easy to operate and the like.
Description
Technical field
The present invention relates to casting equipment, relate to the holding furnace on casting machine specifically.
Background technology
Along with the development of society, the security of equipment more and more comes into one's own.Aluminium wheels air injection machine by air pressure by the aluminium hydraulic pressure in holding furnace in mould, operation holding furnace tightly touch frame lower surface by hydraulic cylinder jacking, in holding furnace, the ejection of aluminium water is one of major Safety of aluminium wheels air injection machine existence, and high temperature aluminum water threatens the safety of operating personnel.And the reason that aluminium water sprays from holding furnace occurs just have after holding furnace is connected with frame by hydraulic cylinder jacking, because fault holding furnace glides automatically, and in jacking state holding furnace, air pressure does not lower, and the phenomenon of aluminium water ejection holding furnace can occur.Aluminium wheels air injection machine frame and holding furnace part is in Fig. 1.
Summary of the invention
The object of the invention is the device that a kind of holding furnace jacking state auto lock will be provided.
Technical scheme of the present invention is: a kind of holding furnace jacking state locking device, comprises frame, walking lock dog leveling device, locking cylinder, walking lock dog, proximity switch, locking adjustment block, adjustment bolt, load-bearing bolt, rear support plate.
Locking cylinder and walking lock dog are arranged in frame, and locking cylinder drives the motion of walking lock dog.Locking adjustment block is arranged on holding furnace by rear support plate.Walking lock dog and locking adjustment block all arrange Self-locking angle on the contact surface, and Self-locking angle scope is 3 °-10 °, and load-bearing bolt coordinates with locking adjustment block, and adjustment bolt coordinates with locking adjustment block.
Proximity switch detects walking lock dog position; Walking lock dog leveling device can finely tune walking lock dog position and angle in the horizontal direction; The height of load-bearing bolt adjustment locking adjustment block, the angle of adjustment bolt adjustment locking adjustment block.
When holding furnace needs work, first by holding furnace by hydraulic cylinder jacking to frame 1 lower surface, the locking cylinder action simultaneously of holding furnace both sides afterwards, is inserted into walking lock dog below locking adjustment block, and proximity switch detects holding furnace after walking lock dog puts in place and just can normally work.When holding furnace needs to fall, the locking cylinder action simultaneously of holding furnace both sides, is withdrawn into home position by walking lock dog, after proximity switch detects signal, then by hydraulic jack, holding furnace is dropped to lowest limit position.
And after using for a long time, due to wearing and tearing and holding furnace distortion, the mating surface of walking lock dog and locking adjustment block can be not parallel, at this moment need by walking lock dog leveling device fine setting walking lock dog position in the horizontal direction and angle, jointly adjusted height and the angle of locking adjustment block by load-bearing bolt and adjustment bolt, finally reach the object of its mating surface locking.
The present invention can meet the safety in production needs of aluminium wheels low pressure casting machine holding furnace, greatly improves safety coefficient, also has that structure is simple in addition, low cost of manufacture, is easy to the advantages such as operation.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is air injection machine frame and holding furnace schematic diagram.
In figure: 1-frame, 2-walks lock dog leveling device, 3-locking cylinder, and 4-walks lock dog, 5-proximity switch, 6-locks adjustment block, and 7-adjusts bolt, 8-load-bearing bolt, 9-rear support plate, 10-holding furnace jacking state forced locking device, 11-holding furnace.
Detailed description of the invention
Details and the working condition of the concrete device proposed according to the present invention is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a device for holding furnace jacking state locking, is made up of frame 1, walking lock dog leveling device 2, locking cylinder 3, walking lock dog 4, proximity switch 5, locking adjustment block 6, adjustment bolt 7, load-bearing bolt 8, rear support plate 9, holding furnace.Locking cylinder 3 and walking lock dog 4 are arranged in frame 1, and locking cylinder 3 drives walking lock dog 4 to move.
Locking adjustment block 6 is arranged on holding furnace by rear support plate 9; Walking lock dog 4 contact surface arranges 5 ° of Self-locking angles, locking adjustment block 6 contact surface arranges 7 ° of Self-locking angles.
Proximity switch 5 detects walking lock dog 4 position; Walking lock dog leveling device 2 can finely tune walking lock dog 4 position and angle in the horizontal direction; Load-bearing bolt 8 and adjustment bolt 7 jointly adjustment lock height and the angle of adjustment block.
In force, by holding furnace by hydraulic cylinder jacking, drive walking lock dog 4 moves by the locking cylinder 3 at two ends afterwards, and walking lock dog 4 runs to and the position of locking adjustment block 6 close contact.Now proximity switch 5 detects that signal is sent to control system, and control system just allows holding furnace to carry out work after acknowledging receipt of signal.
