Description
Technical Field
The utility model relates to a forge drift installation fixing device field, especially relate to a split type structure convenient to drift installation is fixed.
Background
Forging and punching are common processes in forging processing. In closed forging, a flange is typically provided on the punch to close the die cavity for forging. In the process of producing a certain high-pressure valve body, a punch penetrates through a die insert firstly, then the die insert moves forwards together with the punch under the thrust of a punch flange to forge a blank, the punch punches a hole, and the die insert closes a die cavity. However, in forging, the die insert size is often larger than the punch flange size, meaning that the punch flange is subjected to greater damaging forces under the same pressure, causing the flange to transmit plastic deformation resulting in premature punch failure.
Usually, the punch is a whole and is made of die steel, and the tail part of the punch is provided with a section of thread for fixing and connecting. Simply increasing the diameter and thickness of the punch flange to increase its strength undesirably increases the cost of the die and also makes the punch aesthetically unpleasing. Secondly, the large-size punch has overlarge quality, and the large-size punch is not easy to mount without a special clamping tool, so that the time cost is increased, and the production efficiency is reduced. Therefore, the flange structure needs to be changed to solve the problems of deformation and difficult installation on the basis of not increasing the size of the flange.

Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
fig. 1 is a structural diagram of a preferred embodiment of a split structure for facilitating punch installation and fixation according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, the embodiment of the present invention includes:
the utility model provides a split type structure convenient to drift installation is fixed, includes drift 1, screw assembly head 3, flange 2, straight flange line of cut, quasi-circular 6, lagging 5, locating hole 4, the main part of drift 1 is cylindrically, the upper end of drift 1 is provided with screw assembly head 3, 1 outer peripheral face of drift of screw assembly head 3 below is provided with flange 2, the section shape of flange 2 has the quasi-circular 6 of the straight flange line of cut of symmetry for both sides, lagging 5 is flat cylindrical structure, the center of lagging 5 seted up the shape size with the same through-hole of quasi-circular 6, lagging 5 and flange 2 accordant connection overlap on the outer peripheral face of flange 2, locating hole 4 has been seted up to lagging 5 global, locating hole 4 extends and link up to the through-hole to lagging 5's center.
The number of the positioning holes is 4, and the interval between every two adjacent positioning holes is 90 degrees.
Further, the distance between the straight-edge cutting line and the outer peripheral surface of the punch 1 is larger than 0.
Further, the thickness of the sleeve plate 5 is larger than that of the flange 2.
Specifically, as shown in the figure, the left side is a forging punch which consists of a punch 1, a flange 2 and a thread 3. And (4) processing punches 1 with different sizes according to the requirements of the punch holes of the forgings and the sizes of the forgings. In order to increase the strength of the punch flange 2, it is often the main method to increase the thickness and diameter thereof. However, in actual work, the punch flange only plays a role in transmitting pressure and is not directly contacted with a high-temperature forging blank, so that the use of die steel is not free and wastes a little in terms of transmitting pressure. Because the whole surface of the punch is smooth, the appearance is basically a cylinder, a proper tightening part cannot be found in the screwing process, and a special screwing tool is needed. Usually, in order to facilitate the screwing operation, a plurality of blind holes are processed at the root part of the punch 1 so as to put a lever into the blind holes for screwing. However, the existence of the blind hole is not preferable because the strength of the punch is lowered, the stress concentration phenomenon is likely to occur, and the punch 1 is broken.
According to the prior art, it is considered to machine the punch flange 2 into a square circular shape. As shown in the right-hand drawing, the punch flange is machined into a square circle 6, and then the race plate 5 is separately made. The inner hole of the sleeve plate 5 is also square and round, the size of the inner hole is consistent with that of the inner hole of the flange 2, a plurality of holes 4 are formed in the sleeve plate 5, and the peripheral size can be changed according to requirements. During installation, the sleeve plate 5 is sleeved on the flange 2, the lever is placed into the hole 4 to rotate, and the sleeve plate 5 drives the punch to rotate together to be screwed tightly; during forging, pressure is transmitted through the sleeve plate 5, and the thickness of the sleeve plate 5 is slightly larger than that of the flange 2, so that the flange 2 can be effectively protected. The sleeve plate 5 can be made of common structural steel, but the hardness of the sleeve plate is not lower than that of the flange, otherwise the sleeve plate can crush the flange 2 once deformed.
For example, in the forging process of a certain valve body, the assembly structure is used, the material cost of a die is reduced by 8%, the service life of a punch is prolonged by 30%, the installation time of the die is reduced by 40%, the efficiency is improved, and the cost is reduced.
The structure of this application has adopted split type structure, adopts the assembly face of non-round face form, can transmit strength. The beneficial effects obtained by the method are as follows:
1. the punch is convenient to mount and fix, and the efficiency is improved;
2. the cost of the die is reduced, and a punch is protected;
3. the sleeve plate can be made into different sizes according to requirements, can be replaced at any time, and has universality;
4. the processing of the sleeve plate is convenient.
To sum up, the utility model provides a split type structure convenient to drift 1 installation is fixed makes the simple to operate of drift swift, has better improved production efficiency, effectively reduces the mould cost simultaneously, increase of service life.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
