Abstract
The utility model relates to a connecting device for bender and bending upper die, in particular to a fast clamp for the upper die of bender. The technical scheme is that the fast clamp for the upper die of bender comprises a front plate at the upper surface of a rear plate, wherein the bottom edge of the front plate is reduced upwards from the bottom edge of the rear plate, to dislocate the front plate and the rear plate; the top end face of the rear plate is provided with a tapered iron fixedly connected with the front plate; the front plate is provided with a lock plate; the bottom edge of the lock plate extends downwards from the bottom edge of the front plate; the rear plate extending downwards from the bottom edge of the front plate and the lock plate forms a clamp groove; the lock plate is connected with the front plate via at least two bolts above the clamp groove; the back surface of the lock plate is provided with a mounting groove; and an elastic press bar is protruded and embedded in the mounting groove. The fast clamp device can clamp bending upper die via surface contact, having the advantages of good clamp effect and eliminated limitation on the length of upper die.
Description
Technical field
The utility model relates to the jockey of a kind of bender and bending patrix, especially a kind of fast fixture of bender patrix.
Background technology
The fast fixture of bender patrix is widely used on all kinds of benders, is the jockey of bender and Bending Mould, and it is installed on the bender as clamping bending patrix.The bending patrix is contained between jam plate 1 and the back plate 3, usually jam plate 1 is adjusted between 13.2～13.5mm with the back spacing between the plate 3, and during eccentric shank of the key above pressing lower locking plate 1, jam plate 1 is a fulcrum with 2-M10 * 1, jam plate 1 top ejects, jam plate 1 bottom play compress used.Upwards cocked when eccentric handle, reply at jam plate 1 top, returns to spacing 13.2～13.5mm between jam plate 1 and the back plate 3, and at this moment, Bending Mould and this device (rapid connection plate) unclamp, and pull out mould to the left or to the right and can change fast.Because the clamping die shank national standard of Bending Mould is 13 ± 0.018mm, but at this moment there are following several point defects:
When (1), jam plate 1 compresses by eccentric handle, because of off-centre is fixed, and jam plate 1 and the back spacing between the plate 3 is necessarily greater than the die shank thickness of mould, jam plate 1 produces certain angle certainly, thus can only push down a line on die shank plane when compressing, and cannot keep under control the plane, the result is the mould instability, when particularly pressing the weak point mould, cannot keep under control, fall cutter easily.
(2), fix, can not adjust, tight or loose phenomenon often occur because of handle off-centre.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and clamps the bending patrix, clamps effective, as not to be subjected to the bender patrix of patrix length restriction fast fixture with the face way of contact.
The technical scheme that provides according to the utility model, the fast fixture of described bender patrix, comprise the header board that is provided with on the plate front surface of back, the bottom edge of header board is from the bottom edge indentation that makes progress of back plate, making header board be with the back plate shifts to install, the top end face of back plate is provided with header board and is the wedge of fixedlying connected, on header board, be provided with jam plate, the bottom edge of described jam plate is stretched out downwards from the bottom edge of header board, the back plate and the jam plate that stretch out the bottom edge of header board downwards form the clamping cell body, jam plate is connected with header board by two above bolts that clamp the cell body top, on the rear surface of jam plate, have the installation cell body, be embedded with from the elastic compression bar of this installation cell body internal projection at this installation cell body.
Hexagonal lock screw between two bolts, being provided with on the jam plate of upper end.
The utlity model has with the face way of contact clamp the bending patrix, clamp effective, be not subjected to advantage such as patrix length restriction.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the jam plate overall structure schematic diagram in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the utility model mainly is made of jam plate 1, header board 2, back plate 3, wedge 4, elastic compression bar 5 and interior hexagonal lock screw 6 etc.
The fast fixture of bender patrix of the present utility model, comprise the header board 2 that is provided with on plate 3 front surfaces of back, the bottom edge of header board 2 is from the bottom edge indentation that makes progress of back plate 3, making header board 2 be with back plate 3 shifts to install, the top end face of back plate 3 is provided with header board 2 and is the wedge 4 of fixedlying connected, on header board 2, be provided with jam plate 1, the bottom edge of described jam plate 1 is stretched out downwards from the bottom edge of header board 2, the back plate 3 that stretches out the bottom edge of header board 2 downwards forms with jam plate 1 and clamps cell body, jam plate 1 is connected with header board 2 by two above bolts that clamp the cell body top, on the rear surface of jam plate 1, have the installation cell body, be embedded with from the elastic compression bar 5 of this installation cell body internal projection at this installation cell body.
Hexagonal lock screw 6 between two bolts, being provided with on the jam plate 1 of upper end.
In the utility model, 1 is jam plate, and it is to be connected with back plate 3 with the interior hexagonal of 2-M10 * 1 long 40mm (grade is 12.9), adds two Φ 16 * Φ 2 * 23 stage clips resetting as jam plate 1 on 2-M10 * 1 hexagon socket head cap screw.2 is header board, and it is to be connected and fixed with back plate 3 with 2-M10 * 25 hexagon socket head cap screws and 2-Φ 5 spring catch.4 is wedge, and it is to be connected with header board 2 with 2-M8 * 30 hexagon socket head cap screws, and its inclined-plane contacts with the inclined-plane of back plate 3, regulates the height up and down of back plate 3 and wedge 4 by its move left and right.
The utility model improves jam plate 1, on the contact-making surface of jam plate 1 and mould, has inlayed the elastic compression bar 5 of the thick PVC material of 3mm, and eccentric handle changes hexagonal lock screw 6 in adjustable M16 * 1.5 into, like this, no matter the length mould can both compress.Because of the certain decrement of the elastic compression bar 5 of PVC material, can effectively protect die shank, and can have only the compression of adjusting degree of tightness amount.
