Technical Field
The utility model relates to a chassis punches a hole type mould's mould structure especially relates to a chassis punches a hole type mould's hole flanging drift structure.
Background
On the existing progressive die/single-sequence die, the punching process is still the most common processing process. The punch of the existing punching die is arranged on the punch fixing plate, when the punch is damaged and needs to be replaced, the upper die is detached from the punching machine tool, and then the punch fixing plate is detached from the upper die, so that time and labor are wasted in detachment and installation, the labor intensity of workers is increased, and production is delayed.
A standard punch is shown in fig. 1, and typically the punch 00 will have some degree of wear at the ends (i.e., contact surfaces). If the punch 00 is worn seriously, the whole set of dies needs to be detached from the machine tool, and then the dies are opened (the bottom plate/fixing plate and the like need to be unscrewed in a common situation), so that the punch can be knocked out and replaced by a new punch.
The above-described manner of replacing the punch has the following problems: 1. the material cost is high, and the cost of one complete punch is about more than one hundred yuan. 2. The time required for replacing the punch is long, and if the punch is damaged in the using process, the product cannot be smoothly completed on time if the punch is not replaced in time. 3. The process of replacing the punch is complex, a skilled die master is required to replace the punch, and the labor cost is too high.
How to design out and change the hole flanging drift structure of convenient, the good and low chassis punching die of replacement cost of suitability, just become the utility model discloses a direction that the designer thinks.
In view of this, the present invention provides a hole flanging punch structure for a chassis punching die, which is capable of improving the problems of the prior art by means of the research and development and the manufacturing experience of the related industries for many years, and the long-term research and development.
SUMMERY OF THE UTILITY MODEL

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a chassis punches a hole type mould's hole flanging drift structure, is including installing in the body spare of fixed plate and demountable installation in the drift section of body spare below, the drift section set up the mounting hole along the axial, the mounting hole become two segmentation structures including the cover in the outer last hole of body spare and lower hole, the lower downthehole clamp plate of installing, clamp plate and body spare can dismantle and be connected and press the drift section admittedly.
The utility model discloses further preferred scheme: the head of the body piece is provided with a connecting piece of a frustum structure, and the diameter of the lower end of the connecting piece is smaller than that of the upper end of the connecting piece.
The utility model discloses further preferred scheme: the wall surface of the upper hole is a conical surface, the structure of the upper hole is matched with the structure of the connecting piece, and the punch head section is sleeved outside the connecting piece.
The utility model discloses further preferred scheme: the connecting piece be provided with the bolt hole, the clamp plate pass through fixing bolt and connecting piece and can dismantle the connection.
The utility model discloses further preferred scheme: the screw rod of the fixing bolt is inserted into the bolt hole, and the bolt head of the fixing bolt is positioned in the lower hole.
The utility model discloses further preferred scheme: the diameter of the lower hole is larger than that of the lower end face of the upper hole.
The utility model discloses further preferred scheme: the diameter of the pressure plate is smaller than that of the lower hole.
Compared with the prior art, the utility model has the advantages of the body spare is installed at the fixed plate, and drift section demountable installation is in body spare below. That is to say, use the utility model discloses a mould receives to damage under the cracked condition at the hole flanging drift, only need follow body spare on with the drift section dismantle, change new drift section. Compare in the structure setting of traditional whole hole flanging drift of changing, the utility model discloses only need change new drift section, replacement cost reduces to original fifth. The die structure does not need to be disassembled, and the replacement is quick and simple. The mounting hole is of a two-section structure and comprises an upper hole and a lower hole which are sleeved outside the body piece, a pressing plate is arranged in the lower hole, and the pressing plate is detachably connected with the body piece and presses and fixes the punch head section. Make the utility model discloses a stable in structure, the quality of punching a hole is not influenced. The utility model discloses but wide application in type of punching a hole mould.
