In order to achieve the purpose, the technical scheme of the invention is as follows:

the utility model provides a die mould metal sheet elastic sliding ball support, includes fixed baseplate, the last interlock portion that is equipped with of fixed baseplate is equipped with the ball spout in the interlock portion, is equipped with a plurality of balls in the ball spout, the upper portion of ball spout inwards draws in, and the ball spout is exposed at the top of ball.

Furthermore, the spring piece clamping grooves are formed in the side walls of the two sides of the ball sliding groove, the two sides of the spring piece are clamped in the corresponding spring piece clamping grooves, and the balls are placed on the spring piece.

Further, when the spring piece is in an initial state, the distance between the spring piece and the top opening surface of the ball chute is between 2D/3 and 3D/4, the distance between the spring piece and the bottom surface of the ball chute is between D/4 and D/3, wherein D is the diameter of the ball.

Furthermore, the width of the spring piece is the same as the diameter of the balls, and the number of the spring pieces is the same as the number of the balls.

Furthermore, the break angle between the lower side wall of the spring piece clamping groove and the side wall of the ball sliding groove is of a round angle structure.

Furthermore, the upper part and the two ends of the ball sliding groove are both in a round angle structure.

Furthermore, the ball sliding groove is a through long groove arranged at the occlusion part, and two ends of the ball sliding groove in the length direction are clamped with stop blocks matched with the cross section of the ball sliding groove in shape.

Furthermore, the ball sliding groove is provided with a stop screw at the outer side of the stop block.

The invention has the advantages that: the metal sheet contacts with a plurality of balls arranged in the support, when the metal sheet stretches on the support, the balls are driven to roll, so that the metal sheet is prevented from being abraded, meanwhile, spring pieces are arranged under the balls, and when the metal sheet is bent and modeled, the spring pieces can deform along with the pressure of the balls to adapt to the bending requirement, so that the metal sheet is guaranteed to be in smooth contact with the metal sheet constantly, and the metal sheet is suitable for the modeling construction of a complex metal sheet.

Detailed Description

The present invention will be described in further detail with reference to examples.

The present embodiment provides a profiled metal sheet elastic sliding ball bearing, as shown in fig. 1 to 7, which includes a fixed base 1, wherein the fixed base 1 is composed of a fixed plane 11, a supporting sheet 12 and an engaging portion 13 from bottom to top. The fixing plane 11 and the support sheet 12 are in an inverted T shape, and the fixing plane 11 is fixed with the structure through screws.

The shape of the occlusion part 13 is trapezoidal, a through long ball chute 131 is arranged at the upper part, a through long spring piece clamping groove 132 is arranged on the side wall of the two sides of the ball chute 131, and the spring piece 2 is inserted into the spring piece clamping groove 132 along the spring piece clamping groove. Establish a plurality of balls 3 in the ball spout 131, the metal sheet installation is accomplished the back and is contacted with ball 3, when the metal sheet produces flexible on the support, can drive ball 3 rolls to avoid wearing and tearing the metal sheet. Ball 3 with spring leaf 2 cooperation is used, and ball 3 is equal with 2 numbers of spring leaf promptly, and 2 widths of spring leaf equal to 3 diameters of ball, can guarantee like this that every ball 3 receives pressure when, spring leaf 2 changes separately, each other does not influence, and after pressure disappears, can in time kick-back again, make ball 3 return. The arrangement of the spring pieces 2 ensures that the spring pieces 2 can deform along with the pressure of the balls 3 when the metal plate is bent to meet the bending requirement, ensures smooth contact with the metal plate constantly and is suitable for the construction of complicated metal plate molding.

In order to design the ball sliding groove 131 more reasonably, the size of the ball sliding groove 131 is designed in the embodiment. As shown in fig. 5, the height of the ball chute 131 is composed of A, B, C three sections, and the sum of the heights of ABC three sections is the diameter D of the balls 3. Wherein, the length A is equal to the radius D/2 of the ball 3, and the length B is 1/3-1/2 of the radius of the ball 3, namely D/4-D/6. In the range of height B, the two sides of the ball sliding groove 131 are folded inwards, so that the balls 3 can be ensured not to slide out from the top opening after sliding in from the end of the ball sliding groove 131. The height of the O point in fig. 5 is the height of the center of the ball 3 after the original installation, and the position of the P point is the position of the midpoint of the spring plate 2 after the original installation, so when the spring plate 2 is not deformed, the lowest point of the ball 3 after the installation is located at the position of the P point, the top of the ball 3 is exposed out of the ball chute 131 between D/4-D/3, and the distance from the spring plate 2 to the bottom surface of the ball chute 131 is between D/4-D/3, that is, the length of C. The space from the spring plate 2 to the bottom surface of the ball slide 131 is used for accommodating the balls 3 pressed downward.

In this embodiment, the angle between the lower sidewall of the spring slot 132 and the sidewall of the ball sliding slot 131 is a rounded corner 6, so as to ensure the downward smooth spring pressure of the spring piece 2. The upper part and both ends of the ball chute 131 are both of the structure of the round angle 6, which can avoid the sharp corner from scratching the parts which are displaced.

The two ends of the ball chute 131 in the length direction are clamped with the stop blocks 4 matched with the cross section of the ball chute 131 in shape, after the spring piece 2 and the balls 3 are installed, the stop blocks 4 are inserted from the two ends of the ball chute 131 in the length direction, the spring piece 2 and the balls 3 are tightly pressed, meanwhile, the stop screws 5 are installed and screwed on the outer side, and the stop blocks 4 are ensured to be fixed in the ball chute 131.

The above embodiments are only used for explaining the concept of the invention, and not for limiting the protection of the invention, and any insubstantial modifications of the invention using this concept shall fall within the scope of the invention.
