Abstract
The utility model discloses a crimping die which comprises an upper die plate and a lower die plate. The upper die plate is fixedly provided with a left female die and a right female die respectively, and a lower die plate is fixedly provided with a left positioning block and a right positioning block respectively. The left female die and the right female die correspond to the left positioning block and the right positioning block respectively and mutually and are matched with the left positioning block and the right positioning block respectively and mutually. The bottom of a die cavity of the left female die and the bottom of a die cavity of the right female die are respectively provided with an annular circular-arc-shaped forming groove, wherein the inner diameter of the annular circular-arc-shaped forming groove in the bottom of the die cavity of the left female die is larger than the inner diameter of the annular circular-arc-shaped groove in the bottom of the die cavity of the right female cavity. The crimping die is simple in structure, easy to manufacture and convenient to operate. Through crimping of the station of the left female die and the right female die and the station of the left positioning block and the right positioning block, full circular-arc-shaped crimped edges can be formed, and the flat phenomenon of the circular-arc-shaped crimped edges is eliminated.
Description
Technical field
The utility model relates to mould applications, specifically a kind of die with edge-folded.
Background technology
Wiring dit is that the section bar of tubular is rolled into the mould with circular-arc crimping, and the problem that the circular-arc crimping that general die with edge-folded rolls out easily occurs is that circular arc is inhomogeneous, and the width of circular-arc crimping is greater than its height, and circular-arc crimping presents flat, not full.
Utility model content
The purpose of this utility model is to provide a kind of die with edge-folded, and the crimping by left and right die and two stations of left and right locating piece, can roll out fuller circular-arc crimping.
The technical solution of the utility model is as follows:
A kind of die with edge-folded, include upper and lower template, it is characterized in that: on described cope match-plate pattern, be installed with respectively left and right die, on described lower bolster, be installed with respectively left and right locating piece, described left and right die and left and right locating piece are mutually corresponding and cooperatively interact respectively, the bottom of the die cavity of described left and right die is respectively equipped with annular circular-arc forming tank, and wherein the internal diameter of the circular-arc forming tank of annular of the bottom of left die die cavity is greater than the internal diameter of the circular-arc forming tank of annular of the bottom of right die die cavity.
Described die with edge-folded, is characterized in that: on described left and right locating piece, be placed with respectively workpiece.
The beneficial effects of the utility model:
The utility model is simple in structure, makes easily, and easy to operate, the crimping by left and right die and two stations of left and right locating piece, can roll out fuller circular-arc crimping, has eliminated the flat phenomenon of circular-arc crimping.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of die with edge-folded, include upper and lower template 1,2, on cope match-plate pattern 1, be installed with respectively left and right die 3,4, on lower bolster 2, be installed with respectively left and right locating piece 5,6, left and right die 3,4 and left and right locating piece 5,6 are mutually corresponding and cooperatively interact respectively, the bottom of the die cavity of left and right die 3,4 is respectively equipped with annular circular-arc forming tank 7,8, and wherein the internal diameter of the circular-arc forming tank 7 of annular of the bottom of left die 3 die cavitys is greater than the internal diameter of the circular-arc forming tank 8 of annular of the bottom of right die 4 die cavitys.
In the utility model, on left and right locating piece 5,6, be placed with respectively workpiece.
Claims (2)
1. a die with edge-folded, include upper and lower template, it is characterized in that: on described cope match-plate pattern, be installed with respectively left and right die, on described lower bolster, be installed with respectively left and right locating piece, described left and right die and left and right locating piece are mutually corresponding and cooperatively interact respectively, the bottom of the die cavity of described left and right die is respectively equipped with annular circular-arc forming tank, and wherein the internal diameter of the circular-arc forming tank of annular of the bottom of left die die cavity is greater than the internal diameter of the circular-arc forming tank of annular of the bottom of right die die cavity.
