TECHNICAL FIELD
[0001] The utility model relates to die manufacturing technical field more specifically, it relates to a cold upsetting forming die. BACKGROUND
[0002] Although cold upsetting forming has the advantages of high material utilization rate and high production efficiency, for the final forming of a workpiece, it needs to be realized by step-by-step multi-pass cold upsetting, otherwise the workpiece forming quality is poor or cannot be cold upset. Therefore, the cold upsetting die for completing the forming of a workpiece usually has a plurality of forming grooves arranged in sequence thereon to realize the step-by-step cold upsetting forming of the workpiece, but manual displacement is required between adjacent processes, which is complicated to operate and has safety hazards, and the overall effect is not good. Accordingly, the utility model provides a cold upsetting forming die. SUMMARY
[0003] The utility model aims at overcoming the defects of the prior art, and provides a cold upsetting forming die, which has the characteristics of automatic displacement and high forming quality.
[0004] To solve the above technical problems, the utility model aims at realizing the following: the utility model relates to a cold upsetting forming die, which comprises a die body, and forming grooves are arranged on the die body in sequence from left to right. A bar groove is formed on the die body on the front and back of each forming groove. One end of the bar groove is connected to the forming groove, and the other end is connected to the outside. An activity plate is arranged below the bar groove. The activity plate moves up and down relative to the die body. A fixed plate is fixedly connected to the die plate body on the right side of each activity plate. The top of the fixed plate and the top of the activity plate are both inclined from left to right. The lowest point of the upper end surface of the fixed plate is higher than the upper end surface of the die body.
[0005] The utility model is further provided with a linear reciprocating mechanism for controlling the up-and-down movement of the activity plate.
[0006] The utility model is further provided with a pneumatic push rod or a hydraulic push rod as the linear reciprocating mechanism.
[0007] In summary, the utility model has the following advantages: the cold upsetting forming die of the utility model has the advantages of automatic displacement, high forming quality, perfect overall function, and strong practicability, by reserving excess material of the bar groove at both ends of the workpiece, so that the excess material and the workpiece can be moved out of the forming groove when the activity plate moves up. When the activity plate moves up to the point where the lowest point of the upper end surface is higher than the highest point of the upper end surface of the fixed plate on the right side, the excess material and the workpiece automatically slide to the next station. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1It is the whole structure schematic diagram of the utility model. DETAILED DESCRIPTION
[0009] In order to make the person skilled in the art better understand the technical scheme of the utility model, the preferred embodiment of the utility model is described below in combination with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, and not for limiting the utility model patent claim. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.
[0010] The utility model is further illustrated below in combination with the drawings and preferred embodiments.
[0011] Embodiment 1
[0012] Referring to Figure 1 The utility model relates to a kind of cold heading forming die, including mould body 1, mould body 1 is equipped with the forming groove 2 of process in turn from left to right, the front and back of each forming groove 2 is equipped with bar recess 3 opened on mould body, one end of bar recess 3 is connected with the forming groove 2, the other end is connected with outside, the lower of bar recess 3 is equipped with movable plate 4, movable plate 4 moves up and down relative to the mould body 1, the right side of each movable plate 4 is equipped with a fixed plate 5 fixedly connected on mould plate body 1, the top of fixed plate 5 and movable plate 4 is all left high right low inclined arrangement, the upper end surface lowest point of fixed plate 5 is higher than the upper end surface of mould body 1.
[0013] Further, movable plate 4 is equipped with the linear reciprocating mechanism 6 of control up and down motion, linear reciprocating mechanism 6 is pneumatic push rod or hydraulic push rod.
[0014] In the embodiment, forming groove 2 is used as rotary workpiece cold heading forming, the leftmost side is the forming groove for first cold heading forming, the middle is the forming groove for second cold heading forming, and the rightmost side is the forming groove for third cold heading forming. The reserved bar recess 3 is used as extending the reserved bar excess material on workpiece to cooperate with inter-transmission mechanism, realizes automatic switching station function.
[0015] Among them, the principle of automatic switching station is as follows: first, when the workpiece with reserved bar excess material at both ends is placed in the first forming groove to complete cold heading forming, movable plate 4 moves up, and the workpiece is lifted upward until the lowest point of the upper end surface of movable plate 4 is higher than the highest point of the upper end surface of fixed plate, and then stops. At this time, the bar excess material carries the workpiece down the slope, and the workpiece is automatically moved into the second forming groove. In this way, the workpiece will be transferred to the third forming groove in the future, and finally the automatic unloading function is realized.
[0016] The utility model relates to a cold upsetting forming die, through the excess material of the workpiece both ends reserved extension bar groove, make in movable plate make upper shift, can with workpiece excess material from forming groove removal, wait for movable plate upper shift to upper end surface lowest point higher than right side fixed plate's upper end surface highest point, excess material carries workpiece automatic slip to next work station, reach automatic displacement's effect, forming quality is high, integral function is perfect, the practicality is strong.
[0017] Unless otherwise stated, in the utility model, if there are terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship, it is based on the actual shown orientation or positional relationship, just for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the device or element must have a particular orientation, with a particular orientation structure and operation, therefore the utility model describes the orientation or positional relationship term only for example, and can not be understood as the restriction of the patent, for ordinary skilled in the art, can be combined with the embodiment, and according to the specific situation, the specific meaning of the above-mentioned term is understood.
[0018] Unless otherwise stated and limited, in the utility model, if there are terms "set", "connected" and "connected", it should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected, can be directly connected, or indirectly connected through intermediate medium, can be the communication of two elements inside.For ordinary skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to the specific situation.
