Abstract
The invention provides a blocking key of a blocking and drawing insert. The blocking key comprises a body block, a left body block and a right body block, wherein the left body block and the right body block are respectively located at the two sides of the body block, one side of the front and rear sides of the body block is provided with a square lug, and the other side of the body block, and a square slot is formed by the left body block and the right body block; the square slot is not shorter than the square lug, the square lug is connected with an insert connected with a blocking and drawing die, and the left body block and the right body block are respectively connected with a body retaining body of the blocking and drawing die. According to the blocking key provided by the invention, the right body block and the body retaining wall are glued tightly, the body block and the insert are glued tightly, and the middle of one surface of the blocking key is in a hollow shape, the phenomenon that the insert has cracks or is cracked while being subjected to outwards squeezed applied force can be prevented, the insert can be protected, the cost for taking remedial action for the insert with the cracks can be saved greatly, and the economic benefit of an enterprise can be improved.
Description
Technical field
The invention belongs to automobile die piecemeal drawing insert field, especially relate to a kind of piecemeal drawing insert block key.
Background technology
At present, the usual mounting means being applied to automobile die insert shelves key is: on piecemeal drawing die, and insert block key one side is pasted extremely with body barricade, and another side and insert are pasted extremely, as shown in Figure 1.But when producing or matched moulds situation transfers extra quality, because insert and block key paste extremely completely, insert is being subject under an active force outwards squeezed, often there is crackle or split in insert, the insert material of well-known piecemeal drawing die is all generally Cr12MoV, 1.2379 or better material, if there is crackle and cleavage phenomenon in insert, the scheme of usual solution, insert is carried out high annealing, then repair welding processing processes, or directly changes insert, but this cost and duty cycle are very high.Therefore, need the phenomenon that a kind of novel insert block key can avoid insert to occur crackle and split completely badly, greatly reduce costs and duty cycle.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of piecemeal drawing insert block key, and this structure can conveniently apply to, in automobile die piecemeal drawing insert, can avoid the phenomenon that insert occurs crackle and splits completely.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of piecemeal drawing insert block key, comprise main body block, left body block, right body block, described left body block, described right body block lay respectively at the both sides of described main body block, it is characterized in that: before and after described main body block, on side, side is provided with bumping square, opposite side and described left body block, described right body block form square groove, the length of described square groove is not less than the length of described bumping square, described bumping square is connected with the insert of piecemeal drawing die, and described left body block, described right body block are connected with the body barricade of piecemeal drawing die respectively.
Be provided with the first screw hole between described main body block and described bumping square, described left body block, described right body block are respectively equipped with the second screw hole, the 3rd screw hole.
The length range of described square groove is 40-45mm, and the length range of described bumping square is 30-40mm.
Described second screw hole, described 3rd screw hole are counterbore, the overall diameter scope 12-16mm of described counterbore, and interior diameter scope is 7-10mm.
Described main body block, described left body block, described right body block, described bumping square are integrated formed structure.
Owing to adopting technique scheme; left body block of the present invention, described right body block and body barricade paste extremely; main body block and insert are pasted extremely; in hollow shape in the middle of block key one side; avoid the phenomenon that insert occurs crackle or splits when being subject to the active force outwards squeezed; can playing a protective role to insert, greatly saving occurring that the insert of crackle adopts remedial measures caused cost, improves Business Economic Benefit.

Specific embodiment:
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
As shown in Figure 2,3, a kind of piecemeal drawing insert block key, comprise main body block 21, left body block 22, right body block 23, left body block 22, right body block 23 lay respectively at the both sides of main body block 21, before and after main body block 21, on side, side is provided with bumping square 24, opposite side and left body block 22, right body block 23 form square groove, the length of square groove is greater than the length of bumping square 24, bumping square 24 is connected with the insert 3 of piecemeal drawing die, and left body block 22, right body block 23 are connected with the body barricade 1 of piecemeal drawing die respectively.
Embodiment 1
A kind of piecemeal drawing insert block key, comprise main body block 21, left body block 22, right body block 23, left body block 22, right body block 23 lays respectively at the both sides of main body block 21, before and after main body block 21, on side, side is provided with bumping square 24, opposite side and left body block 22, right body block 23 forms square groove, the length range of square groove is 40-45mm, the length range of bumping square 24 is 30-40mm, the length of square groove is not less than the length of bumping square 24, bumping square 24 is connected with the insert 3 of piecemeal drawing die, left body block 22, right body block 23 is connected with the body barricade 1 of piecemeal drawing die respectively.
As shown in Figure 3,4, the first screw hole 25 for lifting by crane is provided with between main body block 21 and bumping square 24, left body block 22, right body block 23 are respectively equipped with the second screw hole 26, the 3rd screw hole 27, second screw hole 26, the 3rd screw hole 27 are counterbore, its interior diameter scope 7-10mm, overall diameter scope 12-16mm.Main body block 21, left body block 22, right body block 23, bumping square 24 are in integrated formed structure.
Embodiment 2
The feature of this embodiment is substantially the same manner as Example 1, but preferably, the length range of square groove is 40mm, and the length of left body block, right body block is 20mm, and the total length of insert block key is 80mm, and the length range of bumping square 24 is 38mm.As shown in Figure 4, Figure 5, the second screw hole 26, the 3rd screw hole 27 are all designed to counterbore, and counterbore envisaged underneath is via hole, the diameter range 14mm of the second screw hole 26, the 3rd screw hole 27, and the diameter range of via hole is 9mm.
The present invention is compared with traditional insert block key 4, and size makes a big difference.The left body block 22 of piecemeal drawing insert block key, right body block 23 paste extremely with body barricade 1, and bumping square 24 and insert 3 are pasted extremely.Like this when producing or matched moulds situation transfers extra quality, be hollow in the middle of piecemeal drawing insert block key 2 one side, such insert 3 can not be split, and namely giving a piece of bad advice also just bad is block key, can play a protective role, greatly reduce cost to insert 3.And change simple, save the replacement cycle, thus improve economic benefit.
Above two embodiments of the present invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
