Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 4, the present invention provides a scratch-free bending die, which is characterized by comprising: the bending device comprises a base 1, a bending piece 2, a positioning piece 3 and a pressing block 4; the base 1 is provided with a pair of bases 1 which are arranged oppositely and at intervals according to a preset distance, the preset distance corresponds to the length of a product, one side of the top of the base 1 is provided with a containing groove 11, the positioning piece 3 is fixed on one side of the containing groove 11, namely the positioning piece 3 and the containing groove 11 are arranged side by side, the containing groove 11 is arranged at the top end of one side opposite to the pair of bases 1, the bending piece 2 is cylindrical, the bending piece 2 is matched with the containing groove 11, the bending piece 2 is placed in the containing groove 11, the circle center of the bending piece 2 is rotationally connected with the side walls at two ends of the containing groove 11 through a rotating shaft, the bending piece 2 can rotate in the containing groove 11, the bending piece 2 is provided with a V-shaped groove 21, the two ends of the bending piece 2 are respectively provided with a counterweight 22, the counterweight 22 is positioned under the groove 21, and the counterweight 22 is used for resetting the bending piece 2, make recess 21 up all the time under the effect of balancing weight 22 when being in unused state, briquetting 4 is located a pair of between the base 1, the distance of being separated by between the size of this briquetting 4 and the base 1 corresponds, during the use, briquetting 4 is connected through the drive arrangement with the external world, panel is placed between two setting elements, when briquetting 4 pushes down, briquetting 4's both sides are pressed on the adjacent one side of a pair of recess 21, under briquetting 4's effect, 2 rotatory drives of bending, and then drive the product and produce deformation, and paste on briquetting 4, thereby accomplish and bend, when briquetting 4 rose, it rises together to drive the product, 2 the effort that loses briquetting 4 of bending this moment, balancing weight 22 drives 2 resets of bending under gravity, be convenient for bend next time.

It can be understood that, through setting up a pivoted 2 of bending on base 1 to set up one on 2 of bending and be the recess 21 of "V" shape, make the product drive 2 of bending under the effect of briquetting 4 and rotate, bend 2 and press the tip of product on 4 outer walls of briquetting, thereby make the product bend, and the product does not have the fish tail, simple structure, the assembly is simple and easy.

Further, holding tank 11 and base 1 keep away from one side interval setting of setting element 3 to make briquetting 4 withstand by base 1 when descending, thereby make its lower base height by base 1 restriction, avoid briquetting 4 to push down too much, make the cooperation between 2 and the briquetting 4 of bending more agree with simultaneously.

Further, for making the mould of bending more harmonious and make the piece 2 of bending more atress, durable, the height of the relative one side of a pair of base 1 will be less than the base 1 and be close to the one side height that is equipped with the setting element to make briquetting 4 avoid being withstood by the side of base 1 when pushing down, and lead to unable messenger's piece 2 of bending rotatory.

Further, the positioning member includes: the fixed station, clamp splice 32, centre gripping spring 33, wherein fixed station and base 1 fixed connection, and be located one side of holding tank 11, be equipped with rectangular channel 311 on one side that the fixed station is close to holding tank 11, clamp splice 32 is located in the both ends of rectangular channel 311 respectively, centre gripping spring 33 sets up between clamp splice 32 and fixed station, its one end and clamp splice 32 butt, the other end and fixed station butt, thereby make clamp splice 32 be close to each other in the effect of spring, thereby can be cliied by clamp splice 32 when making the product place between clamp splice 32, when placing the product, can be according to the width of product, enlarge the distance between the clamp splice 32 under the restriction of product, thereby make the mould of bending can adapt to the product of more sizes, promote the suitability of the mould of bending.

Further, the included angle of the V-shaped groove 21 is smaller than or equal to 90 °, in this embodiment, preferably equal to 90 °, and when the pressing block 4 is away from the certain distance, the side walls of the groove 21 and the pressing block 4 are perfectly attached to each other, so that the product can be formed more standard when being bent.

Further, for the convenience of putting the product between the clamping blocks 32, a chamfer 34 is arranged on the top of one side of the clamping block 32, which is far away from the clamping spring 33, so that the product is more smooth, convenient and quick when being put in.

In summary, the base 1 is provided with the rotatable bending piece 2, and the bending piece 2 is provided with the V-shaped groove 21, so that the product drives the bending piece 2 to rotate under the action of the pressing block 4, the end part of the product is pressed on the outer wall of the pressing block 4 by the bending piece 2, and the product is bent, and the product is free of scratches, simple in structure and easy to assemble.

The above examples, which merely represent one or more embodiments of the present invention, are described in more detail and in more detail, but are not to be construed as limiting the scope of the utility model.
