Description

Line hook finishing die

Technical field

The invention belongs to field of mechanical technique, particularly a kind of shaping dies that is used for the production line hook.

Background technology

The line hook is requisite parts on the apparatuses such as bundled device, belt tightener.The shape of line hook is shown in Fig. 9-1 and Fig. 9-2, and the line hook is to be formed through bending ram by metal wire rod or sheet material.

At present, line generally will adopt four procedures when being hooked in and producing, promptly blank, bend to U-shaped, pressing and bending forming.This four procedure is finished with different moulds by production equipment independently, and the production equipment that needs is more, and the site area that takies is big.Simultaneously, because this four procedure is to finish on different punch presses, semi-finished product need constantly to change machining location, and its production efficiency is low, the processing cost height of product.

Summary of the invention

To the objective of the invention is in order addressing the above problem, a kind of line hook finishing die to be provided, make the line hook can on this mould, finish all manufacturing procedures, thereby improve production efficiency, the reduction production cost of products of line hook.

Purpose of the present invention can realize by following technical proposal: this line hook finishing die comprises a base and a core rod, a recess that supplies wire rod to pass through is arranged on the core rod, it is characterized in that, the top of described core rod is provided with a U-shaped slide block, each side be provided with a pressing slide block at core rod, be provided with a forming punch in the dead ahead of core rod, also be provided with and control the control device that each piece slide block slides.

In above-mentioned line hook shaping mould, the sidepiece of described U-shaped slide block is provided with a wire rod shearing device.After wire rod enters core rod, utilize shearing device to downcut the length of wire that can be made into a line hook.

Cut wire rod at first enters in the recess of core rod, by control device, makes each slide block enter punching press according to certain inferior ordered pair wire rod then, makes it become line hook product.Particularly, wire rod is to be made by following step:

1, the U-shaped slide block strikes out wire rod the semi-finished product of U-shaped;

2, the pressing slide block of the left and right sides flattens half-finished the latter half of U-shaped;

3, the shaping slide block makes semi-finished product the latter half bending of flattening, gets finished product.

Compared with prior art, this line hook shaping mould is positioned over wire rod in the core rod in use, utilizes each slide block from different directions it to be carried out punching press then, that is to say on this mould and can finish all manufacturing procedures, so the speed of production of line hook is fast, high efficiency.Slip by control device control slide block can realize the automated production of line hook, simplifies the cost of production technology and reduction product.

The specific embodiment

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, this line hook finishing die comprises base 1, core rod 5 and each slide block 2, and wherein slide block 2 has the U-shaped slide block 21 that is in core rod 5 tops, is in two pressing slide blocks 22 of core rod 5 left and right sides and is in the forming punch 42 in core rod 5 dead aheads.In the present embodiment, line hook finishing die also comprises a wire rod shearing device 7.This device 7 is made up of counterdie 72 that is in wire rod 8 belows and the patrix 71 that is in wire rod 8 tops, and counterdie 72 is fixed on the base 1, and patrix 71 is fixed on the U-shaped slide block 21.

As shown in Figure 1, be provided with location-plate 6 at the opposite side of U-shaped slide block 21, location-plate 6 is fixed on the base 1.Behind the recess 51 of wire rod 8 by this shearing device 7 and core rod 5, the last roof pressure of its front end is on location-plate 6.At this moment, U-shaped slide block 21 moves down, and patrix 71 is pressed down, and wire rod 8 is cut off.

As shown in Figure 6, in the present embodiment, base 1 is provided with guide rail 11, and each piece slide block 2 all is to be embedded in the guide rail 11 of base 1.Under the effect of external force, slide block 2 can slide along base 1.Two pulleys 3 are all arranged on every slide block 2, and pulley 3 is that secured in parallel is on slide block 2.Pulley 3 can rotate, and between two pulleys 3 certain space is arranged.

As shown in Figure 7 and Figure 8, controlling the control device that each piece slide block 2 slides is a controll block 4 that is arranged at core rod 5 dead aheads and can moves forward and backward.Fixing the control strip 41 with slide block 2 equal numbers on the controll block 4, each control strip 41 is embedded in respectively between two pulleys 3 of above-mentioned each piece slide block 2, and the edge of control strip 41 contacts with pulley 3.In the present embodiment, control strip 41 has three.

Obviously, along with moving forward and backward of controll block 4 and control strip 41, pulley 3 rotates, and slide block 2 also moves.Simultaneously, the curved shape of control strip 41 has determined the direction that slide block 2 slides.

As shown in Figure 7 and Figure 8, in the present embodiment, drift 42 also is fixed on the controll block 4.

As shown in Figure 5, core rod 5 inserts in the base 1, and a fixed mount 52 that is connected with base 1 is arranged in the rear end of core rod 5, is provided with a spring 53 between fixed mount 52 and core rod 5 rear ends.Under the effect of spring 53, core rod 5 is in the position of stretching out forward.

Also be provided with push rod 43 on controll block 4, the circular hole 12 that passes for push rod 43 is arranged on the base 1, push rod 43 can pass circular hole 12 roof pressures on core rod 5.

In fact, to the moving of core rod 5 directions, can disposablely finish whole operations that the line hook is produced by controll block 4.Particularly, the course of work of this line hook finishing die is such:

1, cut off: as shown in Figure 1, wire rod 8 enters in the line hook finishing die, until its front end roof pressure on location-plate 6.At this moment, controll block 4 moves to core rod 5 directions, and the U-shaped slide block 21 that is in core rod 5 tops is moved down, and the patrix 71 that drives shearing device 7 cuts downwards, and wire rod 8 is cut off.

2, strike out U-shaped: as shown in Figure 2, U-shaped slide block 21 continues to move down, and the head of U-shaped slide block 21 bends two of wire rod 8, makes wire rod 8 become the semi-finished product of U font.

3, flatten: as shown in Figure 3, along with the continuation of controll block 4 is moved, U-shaped slide block 21 retreats to initial position; Simultaneously, the pressing slide block 22 that is in core rod 5 left and right sides flattens half-finished the latter half of U-shaped respectively to the center pressing.

4, be shaped: as shown in Figure 4, when controll block 4 was moved further, pressing slide block 22 also stopped pressing, and return initial position; Simultaneously, push rod 43 can pass base 1, and roof pressure is in the rearward end of core rod 5, and makes core rod 5 overcome the elastic force retraction backward of spring 53.At this moment, the semi-finished product of line hook are deviate from from the recess 51 of core rod 5.Meanwhile, drift 42 roof pressures on the controll block 4 are also punching press forward in the half-finished middle part of line hook, makes it to bend to hook-type.Like this, just obtain the line hook finished product shown in Fig. 9-1 and Fig. 9-2.

In fact, varying number and difform control strip 41 can be set, thus the quantity and the manufacturing procedure of the concrete slide block that uses 2 of decision, to produce difform line hook finished product.

As shown in Figure 5, be provided with a shaping pulley 9 below core rod 5, shaping pulley 9 is axially fixed on the base 1.When the drift punching press, shaping pulley 9 plays reduces friction, the effect that the line hook is shaped easily.

After the manufacturing process of finishing a line hook, controll block 4 retreats to original position.Correspondingly, each slide block 2 is also got back to initial position, to carry out work next time.
