Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of moulds, in particular to a continuous die for hardware stamping. Background Art
[0002] Hardware parts refer to tools made of metals such as gold, silver, copper, iron, and tin through processing and casting, and are used for fixing, processing, or decorative purposes. A continuous die for hardware stamping is a die used for metal processing, which can complete multiple processes simultaneously at different positions of a press. Its working principle is that an automatic feeding system pushes a metal strip through all stations of the continuous die, and each station completes one or more stamping processes until the finished product;
[0003] Generally, spring columns are arranged on the bottom die of the continuous die. When the upper die stamps the workpiece, the main function of the spring columns is to provide a reciprocating elastic force to the upper die, ensuring that the die can perform stamping operations smoothly and continuously, and the elastic force of the spring columns helps to reduce the direct impact during stamping, thereby protecting the die and the workpiece from damage;
[0004] However, in practical applications, the spring columns are prone to deformation during continuous stamping operations, and their elastic performance will gradually weaken. Since the deformation of the spring columns is often gradual and difficult to directly observe with the naked eye, it is impossible to give an early warning in time for the operator to take necessary maintenance or replacement measures.
[0005] To solve the above problems, a continuous die for hardware stamping is proposed in this application. Summary of the Utility Model
[0006] Based on the technical problems existing in the background art, the utility model proposes a continuous die for hardware stamping.
[0007] The continuous die for hardware stamping proposed by the utility model includes a lower die and an upper die arranged above the lower die;
[0008] A fixed cylinder is installed at the edge position of the lower die and below the upper die. A cavity is formed in the fixed cylinder, and an elastic buffer is inserted into the cavity from the top of the fixed cylinder;
[0009] Connecting cylinders are installed on both sides of the fixed cylinder. Pressure warning components are installed on the inner walls of the far ends of the two connecting cylinders away from each other. Elastic top components are inserted into the cavity at the near ends of the two connecting cylinders, and the two elastic top components respectively abut against both sides of the bottom end of the elastic buffer.
[0010] Preferably, the elastic buffer includes a buffer rod, a top plate, a first spring, and a first conical head. The buffer rod slides through the top of the fixed cylinder and extends into the cavity. The top plate is installed at the top end of the buffer rod. The first spring is sleeved on the buffer rod and is located between the fixed cylinder and the top plate, and both ends of the first spring are connected to the top of the fixed cylinder and the bottom of the top plate respectively. The first conical head is installed at the bottom end of the buffer rod and is located in the cavity.
[0011] Preferably, the pressure warning member includes a pressure sensor and an alarm. The two pressure sensors are respectively installed on the inner walls of the two connecting cylinders at the ends away from each other, and the two alarms are respectively installed at the ends away from each other of the two connecting cylinders.
[0012] Preferably, a controller is installed on the outer periphery of the fixed cylinder, and the pressure sensor and the alarm are both communicatively connected to the controller.
[0013] Preferably, the elastic top member includes a top rod. The two top rods respectively slide through the ends of the two connecting cylinders close to each other. Second conical heads located in the cavity are installed at the ends of the two top rods close to each other. The two second conical heads respectively abut against both sides of the bottom of the first conical head. A second spring located between the connecting cylinder and the second conical head is sleeved on the top rod, and both ends of the second spring are connected to the connecting cylinder and the second conical head respectively.
[0014] Preferably, a laser displacement sensor is inserted into the top of the fixed cylinder, and the laser displacement sensor is flush with the top of the fixed cylinder. The laser displacement sensor is located below the top plate, and the laser displacement sensor is communicatively connected to the controller.
[0015] The above technical solution of the present utility model has the following beneficial technical effects:
[0016] By providing the elastic buffer, the pressure warning member, and the elastic top member, when the upper die continuously moves downward to punch the workpiece, the bottom of the upper die directly applies pressure to the elastic buffer. After being compressed, the elastic buffer moves downward, pushing the two elastic top members away from each other, and respectively pressing the pressure warning members in the two connecting cylinders. The pressure warning member can be used to monitor the pressure applied to the elastic top member in real time. By providing the elastic top member at the bottom of the elastic buffer, the buffering force when the upper die moves downward can be increased. This structure integrates the elastic buffer and the pressure warning member to realize the real-time monitoring of the deformation state of the elastic buffer during the stamping process of the upper die, effectively warning the weakening of the elastic performance of the elastic buffer, which is convenient for the operator to maintain or replace in time.

Specific embodiments
[0022] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0023] As Figures 1-4 shown, the continuous die for hardware stamping proposed by the present utility model includes a lower die 1 and an upper die 2 arranged above the lower die 1;
[0024] In this embodiment, a fixed cylinder 3 is installed at the edge position of the lower die 1 and below the upper die 2. A cavity 10 is opened in the fixed cylinder 3. An elastic buffer 4 inserted into the cavity 10 is installed at the top of the fixed cylinder 3. The elastic buffer 4 includes a buffer rod 41, a top plate 42, a first spring 43 and a first conical head 44. The buffer rod 41 slides through the top of the fixed cylinder 3 and extends into the cavity 10. The top plate 42 is installed at the top end of the buffer rod 41. The first spring 43 is sleeved on the buffer rod 41 and is located between the fixed cylinder 3 and the top plate 42. The two ends of the first spring 43 are respectively connected to the top of the fixed cylinder 3 and the bottom of the top plate 42. The first conical head 44 is installed at the bottom end of the buffer rod 41 and is located in the cavity 10.
[0025] In this embodiment, connection cylinders 5 are installed on both sides of the fixed cylinder 3. Pressure warning components 6 are installed on the inner walls of the far ends of the two connection cylinders 5 away from each other. The pressure warning component 6 includes a pressure sensor 61 and an alarm 62. The two pressure sensors 61 are respectively installed on the inner walls of the far ends of the two connection cylinders 5 away from each other, and the two alarms 62 are respectively installed at the far ends of the two connection cylinders 5 away from each other. A controller 9 is installed on the outer periphery of the fixed cylinder 3. The pressure sensor 61 and the alarm 62 are both communicatively connected to the controller 9.
[0026] In this embodiment, elastic top components 7 located in the cavity 10 are inserted into the near ends of the two connection cylinders 5. The two elastic top components 7 respectively abut against both sides of the bottom end of the elastic buffer component 4. The elastic top component 7 includes a top rod 71. The two top rods 71 respectively slide through the near ends of the two connection cylinders 5 away from each other. Second conical heads 72 located in the cavity 10 are installed at the near ends of the two top rods 71 away from each other. The two second conical heads 72 respectively abut against both sides of the bottom of the first conical head 44. A second spring 73 located between the connection cylinder 5 and the second conical head 72 is sleeved on the top rod 71, and both ends of the second spring 73 are respectively connected to the connection cylinder 5 and the second conical head 72.
[0027] It should be noted that when the upper die 2 continuously moves downward to punch the workpiece, the bottom of the upper die 2 directly applies pressure to the top plate 42. After the top plate 42 is stressed, it pushes the buffer rod 41 and the first conical head 44 to move downward. The first spring 43 connected to the top plate 42 is compressed. When the first conical head 44 moves downward, it pushes the two second conical heads 72 and the two top rods 71 away from each other. The second spring 73 then undergoes elastic deformation, enabling the top rod 71 to apply pressure to the pressure sensor 61. The pressure applied by the top rod 71 to the pressure sensor 61 can be monitored in real time. When the force applied by the top rod 71 to the pressure sensor 61 is greater than or less than the threshold value, a warning instruction can be sent to the alarm 62 through the controller 9 to notify the staff in a timely manner. And by setting the second spring 73, the buffering force of the first spring 43 can be increased. This structure integrates the elastic buffer component 4 and the pressure warning component 6 to realize real-time monitoring of the deformation state of the first spring 43 during the stamping process of the upper die 2, effectively warning of the weakening of the elastic performance of the first spring 43, and facilitating the operator to maintain or replace it in a timely manner.
[0028] In a further embodiment, a laser displacement sensor 8 is inserted into the top of the fixed cylinder 3, and the laser displacement sensor 8 is flush with the top of the fixed cylinder 3. The laser displacement sensor 8 is located below the top plate 42. The laser displacement sensor 8 is communicatively connected to the controller 9.
[0029] It should be noted that: by means of the provided laser displacement sensor 8, the displacement can be measured by irradiating the bottom surface of the top plate 42 with a laser beam and receiving the reflected light. After the position of the top plate 42 changes, the controller 9 can transmit a warning message to the alarm 62 for warning. With the cooperation of this structure and the function of the laser displacement sensor 8, the elastic performance of the first spring 43 can be further warned.

Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
