Description
Technical Field
The invention relates to the field of stamping dies, in particular to an efficient stamping die.
Background
The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly called a cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part. Along with the improvement of automation technology, new requirements are provided for the working efficiency of the die, the improvement of the efficiency of the die by the existing technology is realized by improving the working rhythm, and in addition, under the condition of high rhythm operation, if the displacement or deformation exists between the upper die and the lower die of the die, if the displacement or the deformation cannot be found in time, the batch scrapping of processed products is caused, and the loss is brought to enterprises.

The invention mainly solves the technical problem of providing the high-efficiency stamping die, which can facilitate the debugging of die assembly stroke of the stamping die, provide a stable high-beat processing process, improve the production efficiency and ensure the stability and reliability of the production process.
In order to solve the technical problems, the invention adopts a technical scheme that: the utility model provides a high-efficient stamping die, mould and lower mould in the package, it still includes control system, displacement detection subassembly and pressure sensor, pressure sensor is embedded at the lower mould upper surface, pressure sensor and control system electric connection, the displacement detection subassembly is by installing go up the rack on the mould and constitute through rotary encoder of support mounting on equipment, install accurate gear in the rotary encoder pivot, rotary encoder with the rack passes through the tooth and contacts the connection, rotary encoder with control system electric connection, control system comprises computational unit, signal converter and display device.
In a preferred embodiment of the present invention, the signal converter converts an analog signal returned by the pressure sensor into a digital signal.
In a preferred embodiment of the present invention, the number of the pressure sensors is 2, and the pressure sensors are respectively embedded in both sides of the upper surface of the lower mold.
In a preferred embodiment of the present invention, the gear ratio of the rotary encoder gear to the rack is 1: 1.
in a preferred embodiment of the present invention, the computing unit is a microcomputer.
In a preferred embodiment of the invention, the control system is installed in a control box on the equipment through a bracket, and the control system further comprises a wireless transmission module.
The invention has the beneficial effects that: according to the efficient stamping die, the high-precision displacement detection device is arranged on the die, so that the die assembly precision of the die is improved, and the debugging work of the production front-end is facilitated. Whether the mould is abnormal or not is judged by checking and comparing the pressure values of the 2 pressure sensors arranged on the lower mould during mould closing, and the reliability and stability of the production process are ensured.
Detailed Description
The following detailed description is given with reference to the preferred embodiments of the present invention so that the advantages and features of the present invention will be more readily understood by those skilled in the art, and the scope of the present invention will be clearly and clearly defined.
The invention relates to a high-efficiency stamping die, which comprises an upper die and a lower die, and further comprises a control system, a displacement detection assembly and a pressure sensor, wherein the pressure sensor is embedded in the upper surface of the lower die, the pressure sensor is electrically connected with the control system, the displacement detection assembly consists of a rack arranged on the upper die and a rotary encoder arranged on equipment through a support, a precise gear is arranged on a rotating shaft of the rotary encoder, the rotary encoder is in contact connection with the rack through teeth, the rotary encoder is electrically connected with the control system, and the control system consists of a calculation unit, a signal converter and a display device.
Further explaining the working principle of the high-efficiency stamping die: the stamping die realizes the processing process of the product through reciprocating stamping action. In the preferred embodiment of the invention, when the upper die moves downwards, the rack arranged on the upper die drives the gear on the rotary encoder contacted with the upper die, at the moment, the rotary encoder works and outputs a digital pulse signal to the computing unit of the control system, and the stroke data of die assembly is sent to the display for displaying through program conversion preset in the computing unit, at the moment, a debugging person can adjust the distance with the shortest die assembly stroke according to the size of a workpiece, so that the effective die assembly stroke is compressed, and the working efficiency is improved. Meanwhile, in the normal production process, the computing unit judges whether the die closing process of the upper die and the lower die is abnormal or not according to die closing stroke data returned by the encoder, so that the production reliability is ensured, and in addition, the computing unit performs punching counting by utilizing the upper die reciprocating data returned by the rotary encoder. When the upper die and the lower die are contacted, the pressure sensors respectively embedded in two sides of the upper surface of the lower die transmit the received pressure signals to the signal converter, the analog pressure signals are converted into digital pressure signals by the signal converter and then transmitted to the calculation unit, the calculation unit compares the preset standard pressure value with the converted pressure, the calculation unit compares the difference value of the two returned pressure signals, if any one of the difference values of the two comparison data exceeds the allowable range, the calculation unit can rapidly send a stop signal to stop the equipment, and the display warns that the pressure difference is abnormal.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
