Abstract
The invention discloses an anti-collision damping oil cylinder of mold casting equipment, and aims to provide better working protection for a mold numerical control machining forming machine, continuously provide a protection effect under the condition that a safety limiting device is damaged or fails and provide variable buffer damping according to the weight of a workpiece. The oil cylinder comprises a cylinder body and a piston in the cylinder body, wherein the cylinder body is of a closed structure; a left chamber and a right chamber on the two sides of the piston are communicated through a buffer flow channel; the middle section of the buffer flow channel is provided with an adjusting cavity and an adjusting plug; the adjusting plug is in threaded connection with the adjusting cavity; openings of the buffer flow channel in the adjusting cavity are positioned in the bottom and the side wall of the buffer flow channel respectively; the section area of the buffer flow channel is smaller than the section areas of the chambers of the cylinder body. According to the scheme, the volume of a circulating part in the adjusting cavity is changed by rotating the adjusting plug, and further the circulation section area of the middle part of the buffer flow channel is changed; free debugging can be realized according to the production condition of the equipment to realize the best damping buffer effect.
Description
Technical field
The present invention relates to the limit damper in a kind of casting mold digital control processing former.
Background technique
Casting mold digital control processing forming technique is the system intergration of the technology such as cad technique, foundry engieering, Numeric Control Technology, cutting technology, is a kind of quick Casting mold manufacturing technology completely newly.Adopt the casting mold numerical control forming machine of this technology can completely without mould, produce the casting sand mold of various shape, for solving the single-piece of foundry goods, the production trial-production of small lot provides new carrier, use this equipment to shorten the manufacture cycle simultaneously, boost productivity, be particularly useful for large part, small lot, the processing of complex-shaped casting mold.Casting mould digital control cutting processing former is made up of the main body containing multiaxis (three axles and more than) moving system, universal or special sand mold cutting tool system and sand-removing system and the special control software design that matches with sand mold milling process.At present, this technology and equipment have been succeeded application in the trial-manufacturing process of the new product exemplar casting molds such as motor.
In casting mold numerical control machining shaping working procedure, three axle linear motion systems are all provided with safety mechanical limit stoper, but once this safety caging device damages or lost efficacy, linear motion system and track girder or other parts of lathe may be caused to collide because of misoperation or misprogrammed, cause the damage of equipment and processing sand mold, even can damage staff time serious.And existing equipment also has the scheme using oil cylinder to carry out stand-by buffer protection, but it can not change its cushioning effect according to the size of equipment and operative workpiece.
Summary of the invention
The invention is intended to provide a kind of casting mold equipment anticollision damping oil cylinder; to provide to casting mold numerical control machining shaping the protection that better works; continue to provide protective action when safety caging device damages or lost efficacy, and variable buffer damping can be provided according to the quality size of workpiece.
Casting mold equipment anticollision damping oil cylinder in this programme, comprise the piston of cylinder body and inside thereof, cylinder body is a seal structure, the left chamber of piston both sides is communicated with by buffer runner with right chamber, buffer runner stage casing is provided with and regulates chamber and adjusting plug, adjusting plug is scyewed joint with adjustment chamber, and the opening of buffer runner in adjustment chamber lays respectively at bottom it and sidewall, and the sectional area of buffer runner is less than the sectional area of cylinder body chamber.
The working principle of this programme is, cylinder body is fixedly connected in the frame of equipment, then by the moving system on the piston rod aligning equipment of cylinder body, when lathe linear motion system exceeds the operation of setting stroke range, piston rod drives piston to move, and because cylinder interior is seal structure, the oil in cylinder body can only be transferred to another chamber by narrow and small buffer runner from a chamber, continue in the moving process of piston to be subject to larger resistance, realize buffer function.The collision produced due to moving system inertia is cushioned by oil cylinder, extends time of collision, makes in the anticollision buffer system outside collisional energy--transfer to moving system, reaches the object of protection moving system and machine tool component.
And this programme can also pass through turn adjusting plug, thus change the volume regulating negotiable part in chamber, and then change the actual internal area in the middle part of buffer runner, according to the PRODUCTION STATUS of equipment, freely can debug, to realize best damping buffering effect.
Further, piston is provided with one-way valve, and fluid when piston resets after action of giving in cylinder body arrives another chamber by one-way valve from a side cavity.When resetting after equipment action of giving, oil need not be refluxed by buffer runner, but can be refluxed by bigbore one-way valve, reduces the cushion effect in reseting procedure, is reset to original state faster.
Further, the bottom of chamber and adjusting plug is regulated to be the taper of mating.Buffer runner can be controlled more accurately and pass through sectional area.
Further, buffer runner is provided with the oil hole with ft connection.Oil hole strictly seals at ordinary times, but can open operations such as carrying out filling oil plant when being necessary.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: cylinder body 1, piston rod 2, piston 3, one-way valve 4, buffer runner 5, oil hole 6, adjustment chamber 7, regulation cock 8.
Embodiment is substantially as shown in Figure 1: cylinder body 1 can need to be fixedly mounted on casting mold numerical control machining shaping according to concrete, then piston rod 2 is connected in the moving system of equipment.Be divided into left cylinder room and right cylinder room by piston 2 in cylinder body 1, piston 3 is provided with bigbore one-way valve 4, and fluid can enter left cylinder room by one-way valve from right cylinder room, when not entering right cylinder room from left cylinder room.
When action of giving, oil plant in cylinder body 1 can only enter right cylinder room by buffer runner 5 from left cylinder room, buffer runner lays respectively at two ends, left and right at the opening of left cylinder room and right cylinder room, left chamber's buffer runner 5 is also provided with and is communicated with outside oil hole 6, and blocked by embolism.
The middle part of buffer runner 5 is provided with and regulates chamber 7, regulate in chamber 7 and be provided with regulation cock 8, regulate the top scyewed joint of chamber 7 and regulation cock 8, its underpart is the taper of form fit, when regulation cock 8 is screwed to bottom, buffer runner 5 is thoroughly blocked, and regulation cock 8 moves up gradually then to regulate in chamber 7 and the sectional area of oil flow warp can be supplied larger.The opening of buffer runner 5 in adjustment chamber 7 lays respectively at bottom it and sidewall.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
