TECHNICAL FIELD
[0001] The utility model belongs to the battery zinc cylinder preparation technical field, specifically relates to a horizontal battery zinc cylinder forming die. BACKGROUND
[0002] Zinc manganese dry battery is cylindrical battery, and the forming of the shell zinc cylinder is formed by the flowing of zinc particle metal under the action of the extruding machine force with the help of the die (that is, cold extrusion forming). Most of the existing battery zinc cylinder forming adopts vertical single station punching forming. The die is mainly composed of two parts: upper die (punching rod) and lower die (die). The zinc cylinder forming process: the upper die (punching rod) moves downward quickly with the slide block of the punch press, extrudes the zinc particles in the lower die (die) cavity, and the zinc particles flow upward between the upper die and the lower die to form the zinc cylinder (extrusion forming) while being extruded quickly. Then the upper die (punching rod) moves upward to exit the lower die (die) cavity, and the zinc cylinder is unloaded from the upper die (punching rod) by the unloader and pushed out of the machine table by the discharging mechanism to the next process for further processing. In this way, the extrusion forming process of the zinc cylinder is completed. In the battery zinc cylinder forming process, the traditional die adjusting mechanism has the problems of low adjusting accuracy, complex adjusting process and low efficiency, which makes it difficult to guarantee the size accuracy and consistency of the produced battery zinc cylinder, and the reason is:
[0003] ①, Since the dry battery shell zinc cylinder is cylindrical, it is required that the uniformity of the wall thickness and the bottom thickness of the outer cavity is as high as possible. The vertical single station punching is adjusted by manually hammering the lower die seat after stopping to adjust the wall thickness deviation. If the force is too strong or insufficient during hammering, it will cause uneven wall thickness. In order to obtain qualified products, experienced workers need to adjust repeatedly for many times. When adjusting the bottom thickness deviation, it is also necessary to stop and adjust the stroke of the punch press slide block and the perpendicularity of the upper die and the lower die, so that the adjustment of the die is very troublesome.
[0004] ②, The vertical single station punching is difficult to achieve uniform wall thickness by manually hammering the lower die seat to adjust the wall thickness. The adjustment deviation is usually between ±0.05mm, so the product accuracy is not high.
[0005] ③, The vertical single station punching can only punch one at a time, and about 80 can be produced per minute, so the production efficiency is low, the production cost is high, and the production demand cannot be met. UTILITY MODEL CONTENTS
[0006] In view of the above-mentioned technical problems, the utility model provides a horizontal battery zinc cylinder forming die to solve the problems of low adjustment precision, complex adjustment process and low efficiency of the existing die adjusting mechanism, the utility model discloses a horizontal battery zinc cylinder forming die, through the design of optimizing the adjusting mechanism, the accurate control of the die adjusting is realized, the production efficiency and product quality are improved, and the production cost is reduced.

[0010] Further, the up and down adjustment eccentric shaft and the left and right adjustment eccentric shaft are provided with fixing nuts for locking the base and the adjusting plate.
[0011] The horizontal battery zinc cylinder forming die is changed from the original vertical single-station punching to horizontal double-station punching in order to punch out battery zinc cylinders with higher quality. Only after the lower die mechanism is fixed and the perpendicularity of the upper die and the lower die is adjusted, the relative position of the adjusting plate and the base can be adjusted by adjusting the rotation angle of the up-down adjusting eccentric shaft and the left-right adjusting eccentric shaft in the horizontal strip hole and the vertical strip hole in the upper die mechanism, so that the punch rod of the upper die mechanism can be adjusted at 360 degrees, thereby obtaining uniform wall thickness with a deviation range generally controlled within ±0.01mm, and the adjustment is convenient and fast. The front and rear movement of the second inclined block in the upper die mechanism is adjusted by adjusting the lifting screw rod, so that the front and rear movement of the upper die punch rod is adjusted, so that two battery zinc cylinders with the same bottom thickness are punched out in the same punch slide block. The punched battery zinc cylinders flow out of the machine table by their own gravity to the next process, and the discharge mechanism pushing out of the machine table in the vertical single-station punching is cancelled, so that the battery zinc cylinders avoid the defect of concave and obtain better appearance quality.
