Abstract

The utility model relates to a fast clamping device for die loading in a bender which comprises a posterior plate, an anterior plate arranged at the front surface of the posterior plate and a lock plate arranged in front of the anterior plate. The anterior plate is arranged between the posterior plate and the lock plate, the bottom edge of the anterior plate retracts upwards, the posterior plate,the anterior plate and the lock plate are arranged in a interlocking manner, the lower parts of which form a clamped groove body; the upper end surface of the posterior plate is provided with a wedgetightly connected with the anterior plate, the lock plate, the anterior plate and the posterior plate are connected by two bolts, the bolts are sleeved with springs which are pressed between the lockplate and the posterior plate. The fast clamping device for die loading in the bender is characterized in that: a transversal handle groove is arranged above two bolt holes of the lock plate, the inner end of the handle groove is articulated with an eccentric handle, and the eccentric handle adpresses the front surface of the anterior plate when folding. The fast clamping device for die loading inthe bender has the advantages of quick and easy operation, stable structure and good clamping effect, being not limited by the time of die loading and the like.

Description

A kind of bender patrix fast fixture

Technical field

The utility model relates to the jockey of a kind of bender and bending patrix, especially a kind of bender patrix fast fixture.

Background technology

A kind of bender patrix clamping device is widely used on all kinds of benders, is the jockey of bender and Bending Mould, and it is mounted on the bender as clamping bending patrix.The bending patrix is contained between jam plate and the back plate, the clamping device that some is arranged on common every bender, the hexagon socket head cap screw that two M10 * 1 are arranged on each clamping device usually, like this when installing or change patrix, just need tens M10 of degree of tightness * 1 hexagon socket head cap screw, requiring great effort time-consuming and needing is equipped with special spanner, very inconvenient; Because the length size of bending patrix is not all identical, the short patrix that has can be cannot kept under control when clamping in addition, falls cutter easily, and is that metal directly contacts with metal, and the easy die surface that damages during clamping causes the product quality produced bad.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of bender patrix fast fixture that a kind of efficient and convenient, Stability Analysis of Structures, clamping are effective, be not subjected to the restriction of patrix length is provided.

The purpose of this utility model realizes by following technical scheme: described bender patrix fast fixture comprises the back plate, be arranged at the header board of back plate front surface and be arranged at the jam plate in header board the place ahead, described header board is between back plate and jam plate, the indentation that makes progress of its base end, back plate, header board, jam plate are and shift to install, and their bottom forms one and clamps cell body; Plate upper surface, described back is equipped with wedge, wedge and header board are fastenedly connected, described jam plate, header board and back plate are connected by two bolts, are set with spring on the bolt, and described spring is pressed between jam plate and the back plate, it is characterized in that: the top of two bolts hole of described jam plate is provided with horizontal handle groove, the inner hinge setting-up eccentricity of handle groove handle when described eccentric handle is closed up, presses the front surface of header board, by lever principle, jam plate compresses the mould that clamps in the cell body.

As further improvement of the utility model, described jam plate bottom has mounting groove on the rear surface, is embedded with the elastic compression bar in the mounting groove, and the surface of described elastic compression bar exceeds the rear surface of jam plate bottom.

As further improvement of the utility model, described elastic compression strip adoption non-metallic elastic material such as silicon rubber, polyamine fat or engineering nylon manufacturing.

The utility model compared with prior art clamps the bending patrix by being easy to open the eccentric handle of closing up, and has advantage swift and convenient to operate; The elastic compression bar of She Zhiing has certain decrement in addition, can increase frictional force and effectively protect the portion that is held of bending patrix, Stability Analysis of Structures, clamp effective, not limited by patrix length.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a positive front view of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in Figure 1 and Figure 2, described bender patrix fast fixture comprises back plate 1, be arranged at the header board 2 of back plate 1 front surface and be arranged at the jam plate 3 in header board 2 the place aheads, described header board 2 is between back plate 1 and jam plate 3, the indentation that makes progress of its base end, back plate 1, header board 2, jam plate 3 are and shift to install, and their bottom forms one and clamps cell body; Plate 1 upper surface, described back is equipped with wedge 9, wedge 9 is fastenedly connected with header board 2, described jam plate 3, header board 2 and back plate 1 are connected by two bolts 10, are set with spring 6 on the bolt 10, and described spring 6 is pressed between jam plate 3 and the back plate 1, the top of two bolts hole 5 of described jam plate 3 is provided with horizontal handle groove 7, handle groove 7 inner hinge setting-up eccentricity handles 8 when described eccentric handle 8 is closed up, press the front surface of header board 2, by lever principle, jam plate 3 compresses the mould that clamps in the cell body.

As shown in Figure 1, described jam plate 3 bottom has mounting groove on the rear surface, is embedded with elastic compression bar 4 in the mounting groove, and it can adopt silicon rubber, polyamine fat or engineering nylon manufacturing, the thickness of described elastic compression bar 4 is 3～5mm, and its surface exceeds the rear surface of jam plate 3 bottoms.

In the utility model, jam plate 3 adopts the hexagon socket head cap screw 10 of two M10 * 1 long 40mm to be connected with back plate 1, is respectively installed with the spring 6 of Φ 16 * Φ 2 * 23 on it, with the jam plate 3 that resets; Header board 2 adopts the hexagon socket head cap screw of two M10 * 25 and the spring catch of two Φ 5 to be connected and fixed with back plate 1; Wedge 9 adopts the hexagon socket head cap screw and the header board 2 of two M8 * 30 to be fastenedly connected, and inclined-plane, wedge 9 lower end contacts with inclined-plane, plate 1 upper end, back, regulates the height up and down of back plate 1 and wedge 9 by the move left and right of wedge 9.

In actual applications, the bending patrix is mounted between jam plate 3 and the back plate 1, when eccentric handle 8 is closed up, the front surface that presses header board 2, jam plate 3 is that the fulcrum trace rotates with two bolts 10 of its below, receives in jam plate 3 bottoms, compresses the bending patrix by elastic compression bar 5; When eccentric handle 8 made progress cocked opening, jam plate 3 is homing under spring 6 effects, and the bending patrix can unclamp and take off.
