Abstract
The utility model discloses a five or six grades of shift fork hot straightening dies, affiliated field is transmission element design technical field, including last mould, lower mould, type groove, counter bore, the main part that goes up mould and lower mould is the cuboid structure, lies in the bottom surface of mould and the top surface of lower mould and has all processed the type groove, and the type groove flute profile altogether that goes up mould and lower mould is the same with the entity shape of five or six grades of shift forks, lies in on the bilateral symmetry line of mould and lower mould the front and back and respectively processes a counter bore, and upward when mould and lower mould compound die, adoption threaded connection spare is connected both fixed, connection convenience, firmly, the utility model discloses a five or six grades of shift fork hot straightening dies, all sharp edge that go up mould and lower mould all fall into 1 45 oblique angles, and the security is good, and the roughness value in type groove is 0.8mm, and the shaping precision of five or six grades of shift forks meets the demands the reasonable price.
Description
Technical field
This utility model relates to driving parts design field, particularly relates to a kind of five or six grades of shift fork thermal recalibration moulds。
Background technology
Shift fork is one gearshift auxiliary component extremely common in the various vehicles and plant equipment, its shape is less regular, traditional shift fork mostly is casting, shift fork efficiency and the precision of the method processing are all very low, easily cause the damage etc. of driving parts in train, shift fork can also adopt forging method to process, forging die in the past is unreasonable due to structural design, delivery bothers, precision is low, affects the service life of driving parts, therefore designs a kind of upper and lower mould easy to connect, firm, safety is good, and five or six grades of shift fork thermal recalibration moulds of reasonable price seem very necessary。
Utility model content
The purpose of this utility model is contemplated to overcome prior art processing shift fork complex process, and efficiency is low, the troublesome defect of delivery, devises a kind of five or six grades of shift fork thermal recalibration moulds, and upper and lower mould is easy to connect, firm, and safety is good, reasonable price。
Solve the technical problem that required by this utility model and can be achieved through the following technical solutions:
A kind of five or six grades of shift fork thermal recalibration moulds, including upper die and lower die, the main body of described upper mould and described counterdie is rectangular structure, also include type groove, counterbore, the end face of the bottom surface and described counterdie that are positioned at described upper mould has all processed described type groove, described upper mould is identical with the physical form of five or six grades of shift forks with the described type groove of described counterdie flute profile altogether, one described counterbore of each processing before and after being positioned on the symmetrical line of described upper mould and described counterdie。
All sharp edges of described upper mould and described counterdie all change into 1 × 45 ° of oblique angle。
The surface roughness value of described type groove is 0.8mm。
Owing to have employed above technical scheme, this utility model has the advantage that
Adopt five or six grades of shift fork thermal recalibration moulds of upper die and lower die, type groove, counterbore combined together design, all sharp edges of upper die and lower die all change into 1 × 45 ° of oblique angle, and safety is good, and the surface roughness value of type groove is 0.8mm, the forming accuracy of five or six grades of shift forks meets requirement, reasonable price。

Fig. 1 is this utility model structure forward sight complete section schematic diagram；
Fig. 2 is this utility model lower die structure schematic top plan view；
In figure each assembly and accompanying drawing labelling be respectively as follows: 1, upper mould；2, counterdie；3, type groove；4, counterbore。
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further。
A kind of five or six grades of shift fork thermal recalibration moulds, including upper mould 1, counterdie 2, type groove 3, counterbore 4, the main body of upper mould 1 and counterdie 2 is rectangular structure, the end face of the bottom surface and counterdie 2 that are positioned at mould 1 has all processed type groove 3, upper mould 1 is identical with the physical form of five or six grades of shift forks with the type groove 3 of counterdie 2 flute profile altogether, before and after being positioned on the symmetrical line of mould 1 and counterdie 2 during the 2-in-1 mould of one counterbore 4 of each processing, upper mould 1 and counterdie, threaded connector is adopted both to be connected fixing, easy to connect, firm。
All sharp edges of upper mould 1 and counterdie 2 all change into 1 × 45 ° of oblique angle, and safety is good。
The surface roughness value of type groove 3 is 0.8mm, and the forming accuracy of five or six grades of shift forks meets requirement, reasonable price。
Five or six grades of shift fork thermal recalibration moulds disclosed in the utility model, all sharp edges of upper mould 1 and counterdie 2 all change into 1 × 45 ° of oblique angle, and safety is good, and the surface roughness value of type groove 3 is 0.8mm, and the forming accuracy of five or six grades of shift forks meets requirement, reasonable price。
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described。Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model。This utility model claims scope and is defined by appending claims and equivalent thereof。
