Description

Technical Field

[0001] This utility model relates to the civilian explosives industry and is used for the preparation process of industrial electronic detonator leads, specifically an industrial electronic detonator lead trimming, peeling, and bending machine. Background Technology

[0002] Currently, in the domestic civilian explosives industry, there are two ways to connect industrial electronic detonator leads to electronic detonator chips: hook welding and riveting. Hook welding offers better reliability, while riveting makes it easier to automate detonator assembly. When hook welding industrial electronic detonator leads to electronic detonator chips, the leads need to be cut, stripped, and bent. Currently, these three tasks are mostly handled by different equipment. After each process is completed, the leads need to be repositioned on another piece of equipment before subsequent work can proceed. This repetitive positioning severely impacts work efficiency, and if any step is not positioned accurately, it will directly lead to scrapping, resulting in a low yield. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an industrial electronic detonator lead wire cutting, stripping and bending machine. When the industrial electronic detonator lead wire and the electronic detonator chip are connected by hook welding, the machine completes the preliminary preparation work for the industrial electronic detonator lead wire, thereby improving work efficiency.

[0039] Figure 1This utility model includes a frame 1, a chain conveyor 2, a workpiece clamping mechanism 3, a shearing mechanism 4, a peeling mechanism 5, and a bending mechanism 6. The frame 1 includes a panel and a support; the panel is placed on the support, and the chain conveyor 2 is placed on the panel; two wedges 8 are provided on the side plate of the chain conveyor 2, respectively, at both ends; multiple workpiece clamping mechanisms 3 are equally spaced on the support plate of the chain conveyor; when the workpiece clamping mechanism 3 is pushed by the chain conveyor 2 and passes the position of the wedges 8, the left and right clamps of the workpiece clamping mechanism 3 are released, and the electronic detonator lead wire 10 is clamped and picked up at this time; when the workpiece clamping mechanism 3 passes the position of the wedges 8, the left and right clamps of the workpiece clamping mechanism 3 are tightened, and the equipment clamps the workpiece. The mechanism performs shearing, peeling, and bending actions. The shearing mechanism 4, peeling mechanism 5, and bending mechanism 6 are sequentially placed on one side of the chain conveyor 2 along the conveying direction of the chain conveyor 2. It also includes a controller 7, which sequentially associates the actions of the three mechanisms—shearing mechanism 4, peeling mechanism 5, and bending mechanism 6—based on the position of the electronic detonator lead wire 10 when it moves on the chain conveyor 2. The controller controls the motor of the chain conveyor 2 and controls the actions of the cylinders on the shearing mechanism 4, peeling mechanism 5, and bending mechanism 6. This is prior art and not the inventive point of this application, so it will not be described in detail in this embodiment. The distance between the shearing mechanism 4, peeling mechanism 5, bending mechanism 6 and the chain conveyor 2 can be adjusted during equipment debugging as needed.

[0040] Figure 2 , Figure 3In the middle, the workpiece clamping mechanism 3 includes a base 11, a left clamp 12, a right clamp 13, two rollers 14, two pins 15, two compression springs 16, and a small shaft 17; the base 11 has a stepped groove in the middle, which includes a large groove and a small groove located at the lower end of the large groove; the left clamp 12 and the right clamp 13 are symmetrically arranged, and the left clamp 12 and the right clamp 13 include a long arm and a short arm, with clamping walls extending upward from the opposite ends of the two short arms and hinge seats extending downward. The two compression springs 16 are respectively placed below the short arms of the left and right clamps and are hinged to the base 11 via the small shaft 17. The upper end of the compression spring 16 contacts and abuts against the lower end surface of the short arm, and the lower end abuts against the stepped surface of the stepped groove in the middle of the base 11. The two long arms are respectively vertically connected to the lower middle of the two short arms. The lower ends of the two long arms pass through the small groove of the stepped groove and are equipped with rollers 14. The rollers 14 are fixed to the long arms of the left and right clamps by the pin 15. The two ends of the lower end face of the wedge block 8 are inclined upwards to form a slope. When the chain conveyor 2 brings the workpiece clamping mechanism 3 holding the electronic detonator lead wire 10 to the position of the wedge block 8, the two rollers 14 in the workpiece clamping mechanism 3, under the action of the wedge block 8, cause the left clamp 12 and the right clamp 13 to rotate and open along the small shaft 17. At this time, the compression spring 16 is compressed, and the electronic detonator lead wire 10 can be clamped or removed. When the chain conveyor 2 moves the workpiece clamping mechanism 3 holding the electronic detonator lead wire 10 away from the position of the wedge block 8, the compression spring 16 returns to its original position, and the left clamp 12 and the right clamp 13 rotate and close.

The shearing cylinder 22 is fixed on the shearing cylinder seat plate 21 at the upper end of the shearing seat 20. The top end of the telescopic rod of the shearing cylinder 22 is fixed to the shearing slide seat 24. When the chain conveyor 2 brings the workpiece clamping mechanism 3 holding the electronic detonator lead wire 10 to the shearing mechanism 4, the control system 7 controls the shearing cylinder 22 to complete the shearing operation of the workpiece and reset it. Then the electronic detonator lead wire 10 enters the next station with the chain conveyor 2.

When the chain conveyor 2 brings the workpiece clamping mechanism 3 holding the electronic detonator lead wire 10 to the peeling mechanism 5, the control system 7 controls the vertical cylinder 22 and the horizontal cylinder 28 to complete the peeling operation of the workpiece and reset. Then the electronic detonator lead wire 10 enters the next station with the chain conveyor 2.

[0043] Figure 6 The bending mechanism 6 in this utility model is fixed to the frame 1 via another base plate 19 and another bracket 18. The bending mechanism 6 includes a bending seat 40, an upper bending blade 34 and a lower bending blade 35, and a bending cylinder 42 for driving the upper bending blade 34 to rise and fall.

The bending cylinder 42 is fixed on the bending cylinder seat plate 41 at the upper end of the bending seat 40, and the top end of the extension rod of the bending cylinder 42 is fixed to the bending slide 44.

[0044] In another embodiment, a guide frame 9 is provided at the unloading end of the chain conveyor 2 and on the panel of the frame 1. The middle part of the guide frame 9 is bent upward into an arc shape, and the upper end of the guide frame 9 is slightly higher than the upper end face of the clamping arm of the workpiece clamping mechanism 3. When the chain conveyor 2 carries the electronic detonator lead wire 10 through the wedge block 8 at this end, the workpiece clamping mechanism 3 releases the workpiece, and the guide frame 9 slides the electronic detonator lead wire 10 off the chain conveyor 2.

[0045] Working process: The chain conveyor runs counterclockwise from right to left with intermittent movement. When the workpiece clamping mechanism 3 passes the right wedge 8, the left and right clamps 12 and 13 in the workpiece clamping mechanism 3 are released. At this time, the electronic detonator lead wire 10 is inserted into the clamp. It is manually inserted and positioned. When the workpiece clamping mechanism 3 leaves the wedge 8, the workpiece clamping mechanism 3 clamps the workpiece and moves to the left. When the workpiece clamping mechanism 3 reaches the shearing mechanism 4, the controller 7 gives a command, and the chain conveyor 2 stops running. At the same time, the shearing mechanism 4 shears the electronic detonator lead wire 10. After the shearing operation is completed, the chain conveyor 2 continues to run. When the workpiece clamping mechanism 3 reaches the stripping mechanism 4... When the peeling mechanism 5 is in operation, the chain conveyor 2 stops running, and the peeling mechanism 5 performs a peeling operation on the electronic detonator lead wire 10. After the peeling operation is completed, the chain conveyor 2 continues to run. When the workpiece clamping mechanism 3 reaches the bending mechanism 6, the chain conveyor 2 stops running, and the bending mechanism 6 performs a bending operation on the electronic detonator lead wire 10. After the bending operation is completed, the chain conveyor 2 continues to run. When the workpiece clamping mechanism 3 reaches the left wedge block 8, the left and right clamps 12 and 13 in the workpiece clamping mechanism 3 are released, and the electronic detonator lead wire 10 is either manually unloaded or slides out of the chain conveyor under the action of the guide frame 9 and the chain conveyor 2.
