DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. EMBODIMENT

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , a kind of upper die clamp for bending machine in the drawing, including fixture main body 1, still including mounting seat 2 in fixture main body 1 upper end, and the connecting mode between mounting seat 2 and fixture main body 1 is fixed connection;Installation rail 3, for the connecting effect to mounting seat 2 and bending machine, installation rail 3 passes through the inside of mounting seat 2 movably;Positioning structure 5, for the locking effect to mounting seat 2, positioning structure 5 is installed in the inside of mounting seat 2.

[0027] Please refer to Figure 5 , the inside of mounting seat 2 is provided with sliding groove 4, the profile shape of installation rail 3 and the connecting portion of mounting seat 2 is equal to the profile shape of sliding groove 4, mounting seat 2 can be moved left and right on installation rail 3 by sliding groove 4, the profile shape of installation rail 3 is "convex" character shape, installation rail 3 is fixedly installed on bending machine, the length of installation rail 3 is equal to the length of bending machine.

[0028] Please refer to Figure 3 , Figure 6 , positioning structure 5 includes the metal plate 501 that can be moved back and forth in the inside of mounting seat 2 by reserving groove, the corner of metal plate 501 is chamfered, silica gel pad 502 is fixedly embedded on the side of metal plate 501 close to installation rail 3, connecting seat 503 is fixedly installed at the center of the side of metal plate 501 away from installation rail 3, the shape of connecting seat 503 is cylindrical, anti-drop piece 504 is movably embedded in the inside of connecting seat 503.

[0029] Please see Figure 6 The anti-detachment plate 504 has a circular cross-sectional shape. An adjusting bolt 505 is fixedly embedded in the center of the side of the anti-detachment plate 504 away from the metal plate 501. The anti-detachment plate 504 can prevent the adjusting bolt 505 from detaching from the connecting seat 503. The adjusting bolt 505 passes through the connecting seat 503. The adjusting bolt 505 can drive the metal plate 501 to move inside the mounting base 2. The adjusting bolt 505 is rotatably connected to the connecting seat 503 through the anti-detachment plate 504.

[0030] Please see Figure 3 , Figure 5 The connection between the adjusting bolt 505 and the mounting base 2 is a threaded connection. There are two sets of positioning structures 5, which are symmetrically distributed. The mounting rail 3 has a toothed array 6 on the side near the silicone pad 502. The connection between the silicone pad 502 and the toothed array 6 is a movable abutment. The toothed array 6 can increase the friction between the silicone pad 502 and the mounting rail 3.

[0031] The working principle of the fixture installation position can be flexibly adjusted: The mounting rail 3 is installed on the bending machine by fixing screws or welding. Its length is equal to the length of the bending machine. When installing the upper die fixture of the bending machine, the operator puts the mounting seat 2 on the main body of the fixture 1 onto the outside of the mounting rail 3. Since the mounting rail 3 is convex, the main body of the fixture 1 will not fall vertically. After moving the main body of the fixture 1 to the designated position, the operator drives the metal plate 501 to move towards the mounting rail 3 by rotating the adjusting bolt 505. This causes the silicone pad 502 to abut against the toothed groove array 6 on the mounting rail 3, locking the position of the main body of the fixture 1 on the mounting rail 3. The position of the main body of the fixture 1 on the mounting rail 3 can be adjusted arbitrarily and without restriction, making the installation position adjustment of the main body of the fixture 1 more flexible. Example

[0032] Please see Figure 2 , Figure 4 This embodiment further explains Example 1: the upper rear end of the mounting base 2 is provided with a second toothed array 7, and the mounting base 2 is engaged with the mounting rail 3 through the second toothed array 7 and the first toothed array 6.

[0033] In this embodiment: Since the bending machine needs to be oiled and maintained regularly, grease may flow into the toothed array 6. The grease and dust impurities mixed together will form dirt that gets stuck in the toothed array 6. At this time, the personnel can engage the toothed array 7 on the rear side of the mounting seat 2 with the toothed array 6, and then move the mounting seat 2 from top to bottom or from bottom to top. This is beneficial for cleaning the dirt in the toothed array 6 of the mounting rail 3 through the mounting seat 2, and prevents the dirt from affecting the contact strength between the silicone pad 502 and the toothed array 6. Example

[0034] Please seeFigure 4 The embodiment is further illustrated for other embodiments, the tooth groove array one 6 is vertically arranged, and the tooth groove array two 7 is obliquely arranged.

[0035] In the embodiment, since the tooth groove array two 7 is obliquely arranged, when the mounting seat 2 is used to clean dirt in the tooth groove array one 6, the mounting seat 2 is in an inclined state, so that the personnel is more labor-saving when cleaning the dirt in the tooth groove array one 6, and the clamp main body 1 can avoid blocking the mounting rail 3.

[0036] It should be noted that the relational terms herein such as first and second and the like are used only to differentiate one entity or operation from another, and do not necessarily require or imply that any such actual relationship or order exists between or among the entities or operations. Moreover, the terms "comprising" or "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that processes, methods, articles or apparatuses including a series of elements not only include those elements, but also include other elements not explicitly listed, or inherent to such processes, methods, articles or apparatuses.
