Abstract
The invention discloses a separation type adjustable forging and pressing punching head, which comprises a punching head body, a guide block, a fixing block and a forming block, wherein the guide block and the fixing block are respectively connected with the two ends of the punching head body, the forming block is connected with the side surface of the punching head body and is positioned between the guide block and the fixing block, and the forming block is connected with the fixing block through a regulating device. The separation type adjustable forging and pressing punching head has the advantages that the structure is in the separation type, and the forming size is adjustable, so the effect that products in various specifications can be processed by one separation punching head can be realized; the fine adjustment of the single-specification products in the tolerance range can be realized, and the product precision is easily ensured; and when components generate flaws of cracks, fracture and the like in the work process, the flaw components can be singly replaced, and the material waste is avoided.
Description
Technical field
The present invention relates to universal joint field, be specifically related to a kind of separation type adjustable forging and press drift.
Background technology
At present in TJ and GI type external sleeve blank of CV joint (structure is as Fig. 1) forging molding process, forging punches used is monolithic devices (structure is as Fig. 2), it is generally to process through line cutting, electric pulse with a round steel material, although this drift can meet the needs of production, but there is many defects: 1, because drift is monolithic devices, therefore, its size must design according to product specification, at least one drift of each specification, cause drift specification various, the expense accumulative total of processing drift is huge, and manageability not; Once the flaw such as crackle, fracture in use appears in 2 drifts, whole drift is scrapped, and causes waste of raw materials; 3, drift specification, size are fixed, and can not carry out adjusted size.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of separation type adjustable forging to press drift, and compact dimensions is adjustable, and a separate type drift can be processed the product of multiple specifications, can change flaw parts, avoids waste of material, and Product Precision easily ensures.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of separation type adjustable forging is pressed drift, comprise punch body, be connected to guide pad and the fixed block at punch body two ends, the forming blocks between guide pad and fixed block in punch body side of interting, described forming blocks is connected with fixed block by adjusting device.
As preferably, described adjusting device comprises the adjusting bolt that is located on fixed block, be located at the first nut that fixed block and adjusting bolt are fixed, and described forming blocks is provided with the first screw socket, and described adjusting bolt coordinates adjusting with screw socket.Adjusting bolt can be carried out compared with precise fine-adjustment the position of forming blocks, and Product Precision easily ensures, and for convenience detach.
As preferably, described punch body is provided with the sliding wing, and the two sides of the described sliding wing are provided with guide rail, and described forming blocks is provided with the groove matching with the sliding wing, and described forming blocks coordinates with guide rail by groove to be interted on the cunning wing.This shaping structures piece difficult drop-off, conveniently moving.
As preferably, described groove adopts oat tail groove structure, and described guide rail adopts the trapezium structure coordinating with oat tail groove structure.The moulding of oat tail groove structure punch die is more convenient, can well be by forming blocks card jail.
As preferably, described punch body is provided with the second screw socket, and described fixed block is provided with the driving screw being connected with the second screw socket, and the outside that is positioned at fixed block on described driving screw is provided with fixed block is fixed on to the second nut in punch body.This structure is easy to regulate, convenient disassembly.
Beneficial effect:
The present invention adopts technique scheme to provide a kind of separation type adjustable forging to press drift, and its compact dimensions is adjustable, can process the product of multiple specifications thereby can realize a separate type drift; Can in the margin of tolerance, finely tune single specification product, Product Precision easily ensures; If there are parts to occur the flaw such as crackle, fracture in the course of work, can change flaw parts separately, avoid waste of material.

Detailed description of the invention
As shown in Fig. 3 to Figure 14, a kind of separation type adjustable forging is pressed drift, comprise punch body 1, be connected to guide pad 3 and the fixed block 4 at punch body 1 two ends, the forming blocks 2 between guide pad 3 and fixed block 4 in punch body 1 side of interting, described forming blocks 2 is connected with fixed block 4 by adjusting device.Described adjusting device comprises the adjusting bolt 5 that is located on fixed block 4, is located at the first nut 7 being fixed with adjusting bolt 5 on fixed block 4, and described forming blocks 2 is provided with the first screw socket 9, and described adjusting bolt 5 coordinates adjusting with the first screw socket 9.Described punch body 1 is provided with two sides and is respectively equipped with the sliding wing 11 of guide rail 111, and described forming blocks 2 is provided with the sliding wing 11, and the two sides of the described sliding wing 11 are provided with guide rail 111, and described forming blocks 2 coordinates with guide rail 111 by groove 21 to be interted on the sliding wing 11.Described groove 21 adopts oat tail groove structure, and described guide rail 111 adopts the trapezium structure coordinating with oat tail groove structure.Described punch body 1 is provided with the second screw socket 10, and described fixed block 4 is provided with the driving screw 6 being connected with the second screw socket 10, and the outside that is positioned at fixed block 4 on described driving screw 6 is provided with fixed block 4 is fixed on to the second nut 8 in punch body 1.
In the present invention, punch structure is separate type, can regulate its compact dimensions by changing different forming blocks 2, can process the product of multiple specifications thereby can realize a separate type drift; Punch body 1 is provided with the sliding wing 11, and by regulating adjusting bolt 5, forming blocks 2 is slided along groove 21 on the sliding wing 11, can in the margin of tolerance, finely tune single specification product, and Product Precision easily ensures; Drift is separate type, if there are parts to occur the flaw such as crackle, fracture in the course of work, can change flaw parts separately, avoids waste of material.In the present invention, punch body 1 can adopt screw bolt and nut to be connected with guide pad 3, also can adopt other connected modes to connect.The present invention is especially better than blank to carry out finishing; Also can rough forge, be suitable for when forging body intensity when lower.
