Abstract
The invention discloses a hole slashing mould, which comprises a hole slashing opening on the hole slashing mould and a nozzle limiting structure installed on the hole slashing opening. The limiting structure is composed of two symmetrical limiting stoppers in vertical direction. The cross section of the protruding part of the limiting stoppers is in the shape of a trapezoid. The hole slashing mould is convenient to use, improves production efficiency and product quality, and reduces production cost.
Description
Technical field:
The present invention relates to mould, particularly a kind of hole expansion die.
Background technology:
It is that other tubing inserts connection for convenience that evaporimeter aluminum pipe, the copper pipe mouth of pipe are carried out reaming.In order to control the insertion depth of tubing, it all is manual operations that the mouth of pipe after the reaming is carried out when spacing, extrudes a stopper slot with hand vice or other instrument on the mouth of pipe, do like this exist production efficiency lowly, the distance and the nonstandard problem of the degree of depth of stopper slot.
Summary of the invention:
The purpose of this invention is to provide a kind of do not carry out by hand spacing, enhance productivity, hole expansion die easy to use, task of the present invention is finished like this, a kind of hole expansion die, it comprises the reaming mouth on the hole expansion die, it is characterized in that: add mouth of pipe position limiting structure on the reaming mouth, position limiting structure is made up of two laterally zygomorphic limited blocks.The cross section of the ledge of limited block is trapezoidal.The present invention has following effect: easy to use, improved production efficiency and product quality, and reduced production cost.
Description of drawings:
Fig. 1 is the axial section of hole expansion die of the present invention.
Drawing explanation: 1, mould, 2, the reaming mouth, 3, upper and lower spacing.
The specific embodiment:
Describe embodiment in conjunction with the accompanying drawings in detail, a kind of hole expansion die, it comprises the reaming mouth 2 on the hole expansion die 1, adds mouth of pipe position limiting structure on the reaming mouth, position limiting structure is formed by two laterally zygomorphic upper and lower spacing 3.The cross section of the ledge of limited block is trapezoidal.Make the moulding of mould and press stopper slot to finish synchronously, this hole expansion die is easy to use, has eliminated the distance and the nonstandard problem of the degree of depth of the manual stopper slot of finishing, and has improved production efficiency and product quality.
Claims (2)
1, a kind of hole expansion die, it comprises the reaming mouth on the hole expansion die, it is characterized in that: add mouth of pipe position limiting structure on the reaming mouth, position limiting structure is made up of two laterally zygomorphic limited blocks.
