[Previous technology] According to the manufacturing of ratchet elements in hand sanitizers such as ratchet wrenches, the ratchet is formed into a tooth shape on the outer side. The processing method is driven by a punching die 7 to gradually process the tooth shape of the material. Processing a relatively sparsely distributed, low-tooth pattern. Through three to four meeting points, 3α and a main four-person stamping process, the materials are gradually manufactured with complete tooth shape and complete tooth shape interval. The method requires several seven broaches to process 'cost ^ and slow operation speed, the reason for the slow operating speed' is to worry about the longitudinally arranged broaches, such as only one broach facing the material at a time, directly punching out the tooth shape This means that the end face of the broach is a horizontal part that hits a relatively horizontal end face. $ The broach is likely to suffer a lot of resistance, causing processing difficulties, rapid wear of the broach, or insufficiently shaped teeth. Redundant, complete and even broken. [New content] The creator has re-designed the above-mentioned method of processing the tooth shape of the ratchet element in actual use.

The knife seat and the movable die are elastically connected. There are buffers for the movable die to be elastically extended 2. The peripheral surface of the tool holder is used to penetrate the other end of the different basic die of the driving rod. The center of the tool holder is also provided with a broach for processing and forming the ratchet element. In order to achieve the above-mentioned creative purpose, the technical means used in the present invention is to provide a broach for a ratcheting machine.

In this creation, the material must be calibrated so that the material b is fed into the broach at the correct position. Among them, the movable mold is set to the elastic movable M240303 type. A correction seat with an inner diameter equivalent to the outer diameter of the material is set in the movable mold. The material is pushed by a power source to compress the movable mold and provide it after the movable mold abuts the knife seat. One is used to correct the position of the material, so that the material smoothly enters the broach to form correctly. 2. The broach of this creation has especially straightened material and low resistance, so that the material can be processed into tooth shape smoothly in one lift.

As shown in the third and fourth figures, the power source (i) continues to apply force. Overcoming correction base (4 3) The friction force between the diameter and the outer diameter of the material (30) drives the movable die (40) to slide along the screw (46) axially and compress the spring (47) until it hits one or two pieces (4 丄) ( 5)), and the driving shaft (11) continues to drive the driving rod (26) and the basic mold (20) forward until the material (30) enters the slot (65) of the broach (60), as As shown in Figure 7, because the broach (60) has a chamfered lead angle (66) at the end angle of the tooth groove (65), it can reduce the instant impact resistance of the material (30) entering the broach (60). Not only does it have a mutual supportiveness for secondary correction, the drive shaft (1 1) is thus started to push the material (30), and the outside of the material (30) enters the tooth groove (65) The tooth profile is cut out of the material part (30) by the tooth groove (65). The tooth profile does not need to be formed in sections. It is cut directly from the tooth tip to the tooth bottom. The scrapped material is M240303. 2) The inclined plane escapes and will not gather in the broach (60). The drive shaft (1 1) will stop until the set point position. [Setting the stroke method, the end of the drive shaft (ii) can be screwed with a screw as shown in the figure. Show The cap head is the setting when the cap head hits the end face of the power source body and stops. Because this is a generally known technology, it is not described in detail in the text.] As shown in the fifth figure, the power source (1 0) makes the drive The shaft (1 1) is displaced in the reverse direction, and the movable die (40) is not pressed by the base die (20), so it is released by the returning elastic force of the spring (47) to release the contact with the knife seat (50). Movable mold 0) quickly moved forward toward the basic mold (20), so that the movable mold (40) and the tool holder (50) returned to a spaced state, and at the same time, the drive shaft (11) /, the basic mold (20) ), While driving the lever (2 6) in the reverse displacement, the joint seat (72) ❸ unloading lever (70) is extended into the broach (60) to push out the material part (30), and let the material part (30) The material can be unloaded between the movable die (40) and the knife I (50). As shown in the eighth figure of the finished product after the material piece (30) is processed, a ratchet element with a tooth shape (32) is formed on the outside. The aforesaid material piece (30) can be completely penetrated outside the feed broach (60), without the need for a return rod (70), so that the material piece (30) forms a tooth shape (32) throughout the axial direction, It is not necessarily restricted to form as shown in the eighth figure. 12 M240303 [Brief description of the diagram] (I) Schematic part The first picture: a top sectional view of the overall configuration of this creation.
