Description

一种感温片冲压设备Temperature sensing sheet stamping equipment 技术领域Technical field
本发明涉及冲压模具技术领域，具体涉及一种感温片冲压设备。The invention relates to the technical field of stamping dies, in particular to a stamping device for temperature sensing sheets.
背景技术Background technique
目前，电饭锅温控器的感温片一般是通过条形薄钢板料带冲压成圆形的毛坯件，再通过喷砂工艺在毛坯件的感温面喷砂制成。冲压时，如果是宽度较短的条形薄钢板料带，采用单个冲压工位的方式进行冲压，而对宽度较长的条形薄钢板料带，则采用并排冲压工位冲压的方式进行冲压。无论是单个冲压工位还是并排冲压工位的方式，冲压工位之间的间距大，料带利用率低，造成较大的资源浪费。而喷砂工艺制作感温面，不但容易造成粉尘污染环境，而且需要另外再增加独立的工序，不利于流水线生产。At present, the temperature sensing sheet of the rice cooker thermostat is generally punched into a circular blank by a strip of thin steel strip, and then sandblasted by a sandblasting process on the temperature sensing surface of the blank. When stamping, if it is a strip of strip steel strip with a short width, it is stamped by a single stamping station, while for a strip of strip steel strip with a long width, it is stamped by a side by side stamping station. . Whether it is a single stamping station or a side-by-side stamping station, the spacing between the stamping stations is large, and the utilization rate of the strip is low, resulting in a large waste of resources. The blasting process produces a temperature-sensing surface, which not only causes dust to pollute the environment, but also requires additional separate processes, which is not conducive to the production of the line.
发明内容Summary of the invention

The finished product is molded at one time, no separate sandblasting process is required, which can greatly improve production efficiency, reduce waste of resources and reduce pollution to the environment; the embossing module and the forming slicing module are arranged in a shape of a shape along the feeding direction, and the presser The small spacing between the bits increases the utilization of the tape and reduces the production cost.

Since the material is punched at the time of forming and slicing, the material belt near the forming and slicing station needs to be stressed. Therefore, a large spacing between the forming and slicing modules is required, which can avoid the influence of adjacent stations during forming slicing.

The area indicated by the circle; the embossing module is arranged in a shape of a product along the feeding direction of the stamping zone, and the forming slicing module comprises an upper forming section 12 and a lower set of punches for the forming section punch provided by the upper template 1 The lower mold forming slicing station 22 of the template 2 is matched with the forming slice punch, and the forming slice module is arranged in a shape of a shape along the feeding direction of the stamping zone, and the forming slicing module and the embossing adjacent to the feeding direction The module spacing is more than one station.
优选的，成型切片模组之间的间距大于压花模组之间的间距。由于成型切片时对料带有冲切，成型切片工位附近的料带需要受力，因此需要成型切片模组之间设置较大的间距，可以避免成型切片时相邻工位的影响。Preferably, the spacing between the formed slicing modules is greater than the spacing between the embossing modules. Since the material is punched at the time of forming and slicing, the material belt near the forming and slicing station needs to be stressed.
