Description

TECHNICAL FIELD

[0001] The utility model belongs to mould field, and particularly relates to a motorcycle oil tank filler anti-theft cup composite forming die with high processing efficiency, low labor intensity, low cost, high yield. BACKGROUND

[0002] The motorcycle oil tank filler anti-theft cup (as shown in the figure) needs four steps of stretching, extruding, punching and protrusion forming, and needs four sets of dies to process step by step. Figure 3 The step-by-step processing mode can meet certain production requirements, but has defects of low operation efficiency, high labor intensity, high labor cost, poor product consistency, low yield, high die cost and inability to effectively meet production requirements.

[0003] The utility model provides a motorcycle oil tank filler anti-theft cup composite forming die which can be once formed, has high operation efficiency, low labor intensity, low labor cost, good product consistency, high yield, low die cost and can effectively meet production requirements. UTILITY MODEL CONTENTS

[0004] To solve the problems of low operation efficiency, high labor intensity, high labor cost, poor product consistency, low yield, high die cost and inability to effectively meet production requirements in the prior art, the utility model adopts the following technical scheme.

[0005] The utility model provides a motorcycle oil tank filler anti-theft cup composite forming die, including upper die seat, forming concave convex die, unloading plate, punching punch, rammer, lower die seat, stretching concave die and stretching trimming punch head, the unloading plate is located in the bottom of upper die seat, the forming concave convex die is fixed in the middle portion of unloading plate bottom, the punching punch is located in the outer circle of forming concave convex die, the rammer is located in the middle portion of forming concave convex die, the stretching concave die is located on the lower die seat and is provided with forming via in the middle portion, the forming via is matched with forming concave convex die, the stretching trimming punch head is located in the middle portion of stretching concave die and is located below the punching punch, and the stretching trimming punch head is completely matched with the shape of the product to be processed.

[0006] Preferably, four guide columns are arranged on the unloading plate, four guide holes are arranged on the stretching concave die, and the guide columns and the guide holes are one-to-one corresponding.

[0007] The utility model has the advantages that one set of die can complete stretching, extruding, punching and protrusion forming, step-by-step operation is not needed, operation efficiency is high, labor intensity is low, labor cost is low, product consistency is good, yield is high, die cost is low, and production requirements can be effectively met. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 3 Product structure schematic diagram to be processed. Specific implementation

[0011] The preferred embodiment of the utility model is described in detail below with reference to the drawings.

[0012] Please refer to Figure 1 , a motorcycle fuel tank filler anti-theft cup composite forming die, it includes upper die seat 1, forming concave convex mold 2, unloading plate 3, punching punch 4, beat material block 5, lower die seat 6, stretch concave die 7 and stretch trimming punch head 8, the unloading plate 3 is located at the bottom of upper die seat 1, the forming concave convex mold 2 is fixed in the middle of the bottom of unloading plate 3, the punching punch 4 is located at the outer circle inside forming concave convex mold 2, the beat material block 5 is located in the middle inside forming concave convex mold 2, the stretch concave die 7 is located on lower die seat 6 and has forming via in the middle, the forming via is matched with forming concave convex mold 2, the stretch trimming punch head 8 is located in the middle inside stretch concave die 7 and is located directly below punching punch 4, the stretch trimming punch head 8 is completely matched with the appearance of the product to be processed, when operating, first put the plate material on the forming via of stretch concave die, upper die seat moves downward and closes completely, as shown in Figure 2 , when closing, forming concave convex mold cooperates with stretch concave die to stretch out an appearance, then continues to close downward, forming concave convex mold cooperates with stretch trimming punch head, completes all stretching, trimming and two small hole punching of side edge, two convex points are also formed simultaneously, these are completed simultaneously, punching punch carries out central large hole punching, beat material block beats the product formed and is unloaded after punching, unloading plate moves upward and completes unloading, so that the final product is processed.

[0013] Among them, four guide columns 31 are arranged on the unloading plate 3, four guide holes 71 are arranged on the stretch concave die 7, the guide column and the guide hole one-to-one correspondence, ensure that it is more smooth and accurate when closing.

[0014] The utility model has the advantages that: a set of mold can complete stretching, extruding, punching and convex point forming by closing once, without step-by-step operation, high operation efficiency, low labor intensity, low labor cost, good product consistency, high yield, low mold cost, effectively meet the production requirements.

[0015] The above embodiment and drawing are not limited to the product shape and style of the utility model, and any ordinary technical personnel in the technical field can make appropriate changes or modifications, which should be considered as not departing from the patent scope of the utility model.
