Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a punching machine for bathroom hardware with automatic punch replacement. Background Art

[0002] In the production process of sanitary valve core gaskets, switch water dividers, etc., a stamping machine is usually required for stamping and manufacturing. The stamping head is driven by a cylinder to stamp the sanitary valve core gaskets and switch water dividers. For example, in the patent number "CN220717394U" and the patent name "A stamping machine", a stabilizing device is set. When the workpiece is placed on the machine body, the pressing block is pressed against the workpiece. At this time, the rotating rod is rotated to press against the sliding sleeve to complete the positioning. The air pump can squeeze the workpiece for stamping, and the rotating rod is rotated. At this time, the pressure spring loses its restraint and generates elastic force to push the pressing block away from the workpiece to remove the workpiece. By setting a stabilizing device, the situation where the workpiece position does not correspond to the air pump is effectively reduced, the stability of the equipment is increased, processing is convenient, and the situation where errors in workpiece stamping are reduced. However, the above structure still has the following problems during actual use:

[0003] In the process of stamping sanitary valve core gaskets, switch water dividers, etc., due to their different production specifications, the required stamping heads and molds are also different. When the punch needs to be replaced, the above-mentioned stamping machine not only needs to be replaced manually, but the replacement process is also complicated and time-consuming, thus greatly reducing the production efficiency.

[0004] Therefore, we proposed a bathroom hardware punching machine with automatic punch replacement that can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a bathroom hardware punching machine with automatic punch replacement, so as to solve the problem raised by the above background technology that when the punch of the punching machine on the market needs to be replaced, not only does it need to be replaced manually, but the replacement process is complicated and time-consuming, thus greatly reducing the production efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a punching machine for bathroom hardware with automatic punch replacement, comprising a base, a column being fixed to the upper surface of the base;

[0007] It also includes: a connecting plate is fixed on the inner side of the column, and a gear ring is slidably connected to the inner side of the connecting plate, and the inner side of the gear ring is fixed to the turntable, and a punching rod is vertically penetrated through the surface of the turntable, and a punching head is fixed to the lower end of the punching rod;

[0008] A servo motor is fixed to the upper surface of the connecting plate by bolts, a rotating shaft is fixed to the output end of the servo motor, a first gear is fixed to the outer side of the rotating shaft, and the outer side of the first gear is meshed with the gear ring.

[0009] Preferably, the lower end of the rotating shaft passes through the interior of the base, and the lower end of the rotating shaft is connected to the base bearing, and a second gear is fixed to the outer side surface of the lower end of the rotating shaft.

[0010] Preferably, a third gear is meshed on the left side of the second gear, and a rotating rod is fixed in the middle of the third gear, and the lower end of the rotating rod is fixed to the base, and the upper end of the rotating rod passes through the upper surface of the base and is fixed to the stamping die.

[0011] Preferably, a stamping groove is provided on the upper surface of the stamping die, and a stabilizing slider is fixed on the lower surface of the stamping die, and the stabilizing slider is connected to the base in a sliding engagement manner.

[0012] Preferably, the punching grooves and the punching heads are arranged in a one-to-one correspondence, and eight groups of the punching heads and the punching grooves are arranged.

[0013] Preferably, a top plate is fixed to the upper end of the column, and a cylinder is vertically fixed through the middle of the top plate, and the lower end of the cylinder is in contact with the punching rod.

[0014] Preferably, the punching rod is vertically slidably connected to the turntable via a return spring, and two ends of the return spring are respectively fixed to the punching rod and the turntable.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the punching machine for bathroom hardware with automatic punch replacement not only does not require manual replacement of the punching rod and the punching head, but also saves time and effort, greatly improves the production efficiency, and does not require a separate replacement of the punching die, which greatly saves time, and is convenient for taking out the bathroom hardware in the punching slot and then putting in new bathroom hardware. The specific contents are as follows:

[0016] (1) The servo motor drives the rotating shaft to rotate, and then the rotating shaft drives the gear ring to rotate together through the first gear, and then the gear ring drives the corresponding punch rod to move to the bottom of the cylinder through the turntable, thereby achieving the effect of automatically replacing the punch head, and there is no need to manually replace the punch rod and the punch head, and the process saves time and labor, greatly improving the production efficiency;

[0017] (2) Furthermore, the rotating shaft will also drive the second gear to rotate together, so that the second gear drives the rotating rod to rotate together through the third gear, and then the rotating rod drives the stamping die fixed at its upper end to rotate together, and then the stamping die drives the stamping slot to rotate together, so that the stamping die drives the stamping slot and the turntable to rotate synchronously, thereby achieving the corresponding punching head and the stamping slot, so that there is no need to replace the stamping die separately, which greatly saves time;

[0018] (3) When the punching die (17) rotates, the stabilizing slider (19) is also driven to rotate together. The sliding engagement connection formed between the stabilizing slider (19) and the base (1) not only makes the punching die (17) more stable when rotating, but also plays a role in supporting the punching die (17);

[0019] (4) By controlling the cylinder to rise, the cylinder no longer squeezes the punch rod. At this time, the elastic force of the reset spring drives the punch rod and the punch head to reset, making it easier to take out the bathroom hardware in the punching groove and put in new bathroom hardware;

[0020] (5) By setting eight sets of punching heads and punching grooves, the use effect is increased, so that it can punch bathroom hardware of different specifications, thereby achieving a better punching effect. BRIEF DESCRIPTION OF THE DRAWINGS
