At the same time, it is necessary to measure again to determine the adjustment size, which is more cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 2 The present embodiment provides a multi-station limiting bracket feeding die, comprising a lower die 1, a guide channel 2 is provided on the upper side of the lower die 1, a punching groove 3 is provided on the inner wall of the bottom of the guide channel 2, and a limiting mechanism 4 is provided on the side wall of the guide channel 2. The product to be processed is moved along the guide channel 2 toward the punching groove 3. In order to reduce the excessive deviation of the processed product during the movement, resulting in the non-corresponding punching position, the limiting mechanism 4 is provided to limit the processing product and limit the movement of both sides of the processed product.

[0021] The specific structure is that the limiting mechanism 4 includes two limiting rods 5 arranged opposite to each other, and the lower mold 1 is provided with a receiving groove 6 on both side walls of the guide channel 2 for the limiting rod 5 to pass through, and the inner wall of the receiving groove 6 is fixedly installed with a shaft column 7, and the limiting rod 5 is rotatably installed on the surface of the shaft column 7, and a linkage unit 8 for maintaining the synchronous rotation of the two limiting rods 5 and a spring 9 for driving the two limiting rods 5 to rotate toward the middle of the guide channel 2 is installed on the lower mold 1 and in the receiving groove 6.

[0022] In the right Figure 1When processing the automobile parts in the mold, the automobile parts are first placed in the guide channel 2, and then moved along the guide channel 2 in the direction of the punching groove 3, passing through the limit rod 5 on the way, thereby opening the two limit rods 5. Because the two limit rods 5 are arranged opposite to each other, and the two limit rods 5 rotate synchronously under the action of the linkage unit 8, when the automobile parts push the two limit rods 5, the limit rods 5 are kept symmetrical with respect to the middle part in the width direction of the lower mold 1 regardless of their positions, and then under the action of the limit rods 5, the automobile parts are always kept in the middle position, and when the tail of the automobile parts moves to the limit rods 5, under the action of the spring 9, the two limit rods 5 abut against the side wall of the tail of the automobile parts again, thereby automatically realizing the limit operation of the automobile parts and improving the processing accuracy.

[0023] See also Figure 3 and Figure 4 The linkage unit 8 includes two mutually parallel guide rods 81 fixedly installed in the middle part of the width direction of the lower mold 1, the axial direction of the guide rod 81 is parallel to the length direction of the lower mold 1, and a slider 82 is slidably installed on the two guide rods 81. Connecting rods 83 are hinged on both sides of the slider 82, and a transfer rod 84 is hinged on the side of the connecting rod 83 away from the slider 82. The spring 9 is installed on the guide rod 81, and one side of the spring 9 is fixedly connected to the slider 82. A limit block 85 for guiding the transfer rod 84 to move along the width direction of the lower mold 1 is fixedly installed on the lower mold 1, and a push plate 86 is fixedly installed on the side of the transfer rod 84 away from the connecting rod 83. The limit rod 5 is located on one side of the placement groove 6 and abuts against the push plate 86.

[0024] When the automobile parts push the two limit rods 5 to rotate around the shaft column 7 respectively, the limit rod 5 will push the push plate 86 to move in the direction of the connecting rod 83, thereby driving the transmission rod 84 to move together. Figure 4 It can be seen that the axes of the two connecting rods 83 form an angle with each other, so that when the transmission rod 84 moves, the ends of the two connecting rods 83 away from the slider 82 will be pushed to move toward each other synchronously, thereby pushing the slider 82 to move away from the transmission rod 84. The movement of the slider 82 drives the spring 9 to stretch, so that under the action of the elastic potential energy of the spring 9, the two limit rods 5 abut against the two sides of the automobile part. When the two limit rods 5 suddenly lose the abutment with the side wall of the head of the automobile part, under the action of the elastic potential energy of the spring 9, the two limit rods 5 will move to the middle of the guide channel 2, and then abut against the side wall of the tail of the automobile part, and realize the limit again.

[0025] See also Figure 1 The guide rod 81 is located at one side of the guide channel 2 and is rotatably mounted with a roller 10, the roller 10 being axially perpendicular to the bottom wall of the guide channel 2. The roller 10 contacts the side wall of the automobile part, thereby reducing the scratches of the limit rod 5 on the automobile part.

[0026] See also Figure 3 and Figure 4The limiting rod 5 is connected to the push plate 86 through the bearing rod 11, and the bearing rod 11 is fixedly connected to the limiting rod 5. A sleeve 12 is rotatably mounted on the surface of the bearing rod 11, and the sleeve 12 abuts against the push plate 86. Thus, the sliding friction between the push plate 86 and the bearing rod 11 is converted into the rolling friction between the push plate 86 and the sleeve 12, reducing energy loss.

[0027] See also Figure 3 and Figure 4 A baffle 13 is slidably mounted on the two guide rods 81, a side of the spring 9 away from the slider 82 is fixedly mounted on the baffle 13, a positioning unit for adjusting the position of the baffle 13 is mounted on the lower die 1, the positioning unit includes a threaded rod 14 rotatably mounted on the lower die 1, a threaded hole 15 threadedly matched with the threaded rod 14 is opened on the baffle 13, a driving member 16 for driving the threaded rod 14 to rotate is mounted on the lower die 1, and the driving member 16 can be manually operated or operated by a motor.

[0028] By rotating the threaded rod 14, the threaded rod 14 drives the baffle 13 to move axially along the guide rod 81. When the baffle 13 moves away from the slider 82, the spring 9 will continue to stretch, and the internal elastic potential energy will increase, thereby increasing the interaction force between the limit rod 5 and the automobile parts. When the baffle 13 moves in the direction of the slider 82, the spring 9 will contract. The internal elastic potential energy will decrease, thereby reducing the interaction force between the limit rod 5 and the automobile parts, thereby facilitating the control of the limit force of the limit rod 5 on the automobile parts, facilitating installation and disassembly, and facilitating the control of the clamping and limiting force of the limit rod 5 on the automobile parts.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
