Description
Technical field
The present invention relates to a kind of production methods to belong to high more particularly, to a kind of method for producing motor-car elbow piece
Iron motor-car rubber product technical field.
Background technology
Currently, high ferro motor-car is in the process of moving, there are uneven phenomenons with compartment bonding pad in compartment, thus easily
Windage is generated, excessive windage can influence the consumption of energy；It is energy-saving and environment-friendly instantly in promotion, it should to reduce energy as far as possible
Consumption；Meanwhile high ferro can be made by pressure, outside by pulling force when turning on the inside of the junction between compartment and compartment
Rub between compartment interconnecting piece, influence its service life；In addition, since junction air-tightness is bad, when high ferro is in height
While speed traveling, noise problem can make passenger feel uncomfortable caused by air-tightness is bad, influence the service quality of railway.
For this reason, it may be necessary to which soft strength elbow is arranged between compartment and compartment, conventional soft strength elbow combines for canopy cloth, one
As using sewing bonding method, not only influence beautiful, the defects of also sewing falls off, rain leakage；And conventional canopy cloth etc.
Traditional material is rigidly big, under the effect of external force, is not likely to produce ess-strain, and bullet train generates stretching when turning lane change
Compressive deformation is larger, is highly vulnerable to breakage fixing piece aluminium section bar or causes to be sewed and connected thread breakage；Meanwhile traditional conventional material is fire-retardant past
It is fire-retardant to be more considered as combustion fumes density and smog poison according to the reality of train sealing space toward oxygen index (OI), Fire retardant grade is focused on
Property, it is more secure to personal safety in this way；In addition, bullet train service condition is severe, deflect repeatedly, the round-the-clock exposure of high/low temperature
In outdoor, the materials such as conventional rubber parts easily ageing failure；Therefore, there is an urgent need for a kind of completely new soft strength elbow structures and production
Method solves the above problems.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide the high motor-car elbow piece productions of a kind of production, efficiency of assembling
Method.
The object of the present invention is achieved like this：
A kind of motor-car elbow piece production method, the method include following steps：

The width on defective material side；
The step realizes that the grinding device includes the guide rail being installed on ground, the walking based on grinding device
The traveling wheel of trolley walks on guide rail, and the side wall of the walking dolly is equipped with a pair of of polishing roller and at least a pair of of niproll,
Above-mentioned offset plate is held between niproll and polishes the surface of offset plate to form two bond regions by roller of polishing；
Step 2 is cut：The offset plate for polishing bond regions is cut into sheet material of corresponding size；
Step 3, hot pressing：The step is based on hot press, the hot press include the pushing mold that is mounted on the base and
The upper die tool being installed on pressure head, the both sides of upper die tool are equipped with acupuncture treatment, on the bottom surface of the upper die tool vertically
It is vertically provided with positioning column, the location hole being inserted into for positioning column is provided on the top surface for pushing mold；Sheet material is positioned over down
Between compression mould and upper die tool, during pressure head drives upper die tool to move down, sheet material is by thermal softening, at this time by sheet material both sides
Puncture is articulated in acupuncture treatment, and then pressure head drives upper die tool to continue to move down until sheet material is pressed together on completely and push mold and upper
It is molded between compression mould；
Step 4, sizing：Elbow piece after molding is positioned over cooling and shaping on shaper；The shaper includes
Lower shaper and upper shaper are provided with fixed slot on the upper surface of the lower shaper, and the upper shaper is embedding
It is placed in fixed slot, the both sides of the top surface of the upper shaper are equipped with handle, and elbow piece after molding is positioned over sizing
In slot, it is then inserted into shaper；
Step 5, deburring：By the extra residual rim charge excision of surrounding.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is hot-forming by rubber, greatly improves preparation efficiency；And grinding device is utilized before cutting
It is polished edge bonded part consequently facilitating improving cohesive force when being bonded, therefore substitute often using quickly cohesive mode
Traditional sewing mode is advised, equipment efficiency is greatly improved；And make it not by the design of acupuncture treatment in hot pressing
Meeting contraction distortion, to greatly improve the quality of product.
