Description

Technical Field

[0001] The utility model belongs to the technical field of wire drawing dies, and particularly relates to a material supporting frame structure of a wire drawing die grinding machine. Background Technique

[0002] A wire drawing die is a die specifically used for metal drawing to manufacture metal wires. The wire drawing die includes an outer sleeve and a die core. In the processing of the wire drawing die, it is necessary to perform hole grinding on the die core of the wire drawing die; the wire drawing die material supporting frame is a structure on the wire drawing die grinding machine for supporting and placing the wire drawing die blank. The existing wire drawing die material supporting frame is a fixed structure. Although the wire drawing die is driven by the driving runner at the bottom during the processing, the height of the wire drawing die cannot be adjusted. This makes the position and height of the wire drawing die unable to change when it is being ground. The grinding position of the wire drawing die by the grinding needle is fixed, and the metal debris generated by grinding is likely to scratch the inner wall of the wire drawing die under the drive of the grinding needle, affecting the finished product effect of the wire drawing die. Content of the Utility Model

[0003] The purpose of the utility model is to provide a material supporting frame structure of a wire drawing die grinding machine to solve the problems of the existing wire drawing die in the using process mentioned in the above background technique.

[0006] Preferably, the load-carrying tray is made of rubber material, and a through hole is arranged at the center of the load-carrying tray.

[0007] Preferably, one or two groups of lifting cylinders are selected, and the lifting cylinders drive the support plates to perform lifting and fine adjustment.

[0008] Preferably, the outer surface of the guide rod is polished, and a sliding sleeve is arranged at the connection position between the frame plate and the guide rod.

[0009] Preferably, the number of the support plates is set based on the number of the lifting cylinders, and the support plates and the frame plates are integrally formed.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The lifting cylinder can drive the rack plate to make periodic lifting micro-movements, so that during the processing, the contact height between the inner hole of the wire drawing die core and the grinding needle is variable. The metal chips generated by grinding will fall due to the gap between the grinding needle, thus ensuring that the inner wall is not scratched during the grinding process and ensuring the quality of the processed wire drawing die.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Refer to Figure 1 , a material supporting rack structure of a wire drawing die grinding machine, including a bottom plate 1, a front baffle 2 is arranged on the bottom plate 1, two groups of guide rods 3 perpendicular to the bottom plate 1 are arranged at the rear side of the front baffle 2, a group of rack plates 4 are sleeved on the two groups of guide rods 3, multiple groups of material trays are installed on the rack plate 4, a group of support plates 5 are installed at the bottom of the rack plate 4, and a lifting cylinder 6 is arranged at the bottom of the support plate 5, and the lifting cylinder 6 drives the rack plate 4 to make a lifting movement along the guide rod 3.

[0016] Aiming at the problem that the material supporting rack of the existing wire drawing die grinding machine is a fixed structure, and during the grinding process of the wire drawing die, the metal chips generated by grinding are likely to scratch the inner wall of the wire drawing die under the drive of the grinding needle, affecting the finished product effect of the wire drawing die, this technical solution is provided with a group of movable and liftable material supporting racks. Specifically, multiple groups of material trays are arranged on the rack plate 4, and the wire drawing dies are placed on the material trays in batches for processing. The two ends of the rack plate 4 are respectively sleeved on the guide rods 3, and the bottom of the rack plate 4 is connected with a lifting cylinder 6 through a support plate 5. The lifting cylinder 6 drives the rack plate 4 to make a lifting movement, and the guide rod 3 limits the movement of the rack plate 4 to keep the rack plate 4 stable during lifting. Thus, during the grinding process of the wire drawing die, the blank of the wire drawing die is adjusted periodically up and down, the contact height between the grinding needle and the inner hole of the wire drawing die core is variable, and the metal chips generated by grinding will fall due to the gap between the grinding needle, so as to ensure that the inner wall is not scratched during the grinding process and ensure the quality of the processed wire drawing die.

[0017] Furthermore, the material tray includes a driving runner 7 and a load tray 8, and the load tray 8 is arranged directly above the driving runner 7.

[0018] With this technical solution, the driving runner 7 is connected by a belt driving mechanism, and the driving mechanism drives the driving runner 7 to rotate, thereby driving the load tray 8 and the wire drawing die blank placed on the load tray 8.

[0019] Furthermore, the load tray 8 is made of rubber material, and a through hole is provided at the center of the load tray 8.

[0020] With this technical solution, the load tray 8 is directly used to support and carry the wire drawing die blank. The load tray 8 is made of rubber material, which can buffer deformation and absorb vibration. At the same time, the load tray 8 made of rubber material has a high friction coefficient, which can effectively prevent the wire drawing die from falling off.

[0021] Furthermore, one or two lifting cylinders 6 are selected, and the lifting cylinders 6 drive the support plate 5 to make lifting fine adjustment.

[0022] The lifting cylinders 6 are symmetrically arranged along the symmetry line of the frame plate 4. When one lifting cylinder 6 is set, the lifting cylinder 6 is exactly set at the symmetry center line of the frame plate 4. When two lifting cylinders 6 are set, the two lifting cylinders 6 are respectively arranged on the left and right sides of the symmetry line of the frame plate 4, and the two groups are symmetrically arranged. The setting of the lifting cylinders 6 can make the lifting movement of the frame plate 4 more stable, so that the lifting movements at different positions on the frame plate 4 are synchronized; the movement mode of the lifting cylinders 6 is set by program control and performs periodic lifting. The fine adjustment of the lifting cylinders 6 means that the amplitude of the lifting movement is small, and the lifting height is less than the thickness of the wire drawing die blank.

[0023] Furthermore, the outer surface of the guide rod 3 is polished, and a sliding sleeve is provided at the connection position between the frame plate 4 and the guide rod 3.

[0024] Furthermore, the outer surface of the guide rod 3 is smooth and is connected to the frame plate 4 through a sliding sleeve, which is beneficial to reducing friction and making the lifting of the frame plate 4 stable.

[0025] Working principle: The material supporting frame is set to be liftable and movable. Multiple groups of material trays are arranged on the frame plate 4. The wire drawing dies are placed on the material trays in batches for processing. The two ends of the frame plate 4 are respectively sleeved on the guide rods 3. The bottom of the frame plate 4 is connected with a lifting cylinder 6 through a support plate 5. The lifting cylinder 6 drives the frame plate 4 to make a lifting movement. The guide rods 3 limit the movement of the frame plate 4 to keep the lifting of the frame plate 4 stable. When processing the wire drawing die, the lifting cylinder 6 can drive the frame plate 4 to perform periodic lifting fine adjustment, so that during the processing, the contact height between the inner hole of the wire drawing die core and the grinding needle is changed, and the metal chips generated by grinding will fall because there is a gap between them and the grinding needle, thereby ensuring that the inner wall is not scratched during the grinding process and ensuring the quality of the processed wire drawing die.
