Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically to a cutting tool structure for bending processing. Background Technology

[0002] Metal bending is a common operation in the field of mechanical manufacturing. Bending knives are used to perform edge bending operations on cabinet panels, cabinet doors, etc. For example, hinge knives are used for bending. Another example is a plastic crusher knife with a bending head structure, as announced in CN201154319Y. The knife body and the knife head are set separately and independently. The knife head is also an independent split structure. The knife head and the knife body are connected as one piece by bolts.

[0003] However, current replaceable cutting heads are fixed to the cutting head body with a single bolt. When subjected to external forces in different directions during processing, the bolt is prone to loosening, causing the cutting head to deviate. Therefore, we propose a cutting head structure for bending processing to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this utility model is to provide a cutting head structure for bending processing, so as to solve the problem mentioned in the background art that the existing replaceable cutting head is fixed to the cutting head by a single bolt, which is prone to loosening of the bolt and causing the cutting head to deviate when subjected to external forces in different directions during processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending tool head structure, including a tool holder, a groove is provided inside the lower end of the tool holder, a tool head is provided below the groove, a slider is provided at the upper end of the tool head, the slider and the tool head are integrally formed, and the tool head is slidably connected to the groove in the tool holder through the slider. Both sides of the tool holder are provided with transverse threaded holes that penetrate into the slider, and the rear end of the tool holder is provided with a longitudinal threaded hole that penetrates into the slider.

[0006] Preferably, the two sides of the tool holder are threadedly connected to the slider through transverse screw holes and transverse locking screws.

[0007] Preferably, the rear end of the tool holder is threadedly connected to the slider via a longitudinal threaded hole and a longitudinal locking screw.

[0008] Preferably, two side limiting guides are provided on both sides of the inside of the slide groove, and two guide grooves are provided on both sides of the slider, and the guide grooves of the slider are slidably connected to the side limiting guides.

[0009] Preferably, a rubber pad is provided on the inner wall of the chute.

[0010] Preferably, the upper end of the tool holder is provided with a connecting block, and the connecting block is integrally formed with the tool holder.

[0011] Preferably, both the tool holder and the tool head are made of alloy material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The tool head and tool holder of this utility model are connected by sliding block, and the tool head is locked and fixed from two directions by transverse locking screw and longitudinal locking screw respectively. In this state, the tool head is subjected to transverse and longitudinal locking forces at the same time, which has strong stability. When the processing force is applied, it can offset multi-directional stress and extend the processing life. This solves the problem that the existing replaceable tool head is fixed to the tool body by a single bolt. When subjected to external forces in different directions during the processing, the bolt is easy to loosen and the tool will deviate.

[0014] (2) When the slider of the cutter head is slidably connected with the slide groove on the cutter holder, the guide grooves on both sides of the slider can engage with the side limit guide strip of the slide groove sidewall, thereby playing the role of upper and lower limit support and further improving the stability of the cutter head after connection.

[0015] (3) By setting a rubber pad on the inner wall of the slide groove, the rubber pad is a flexible material. On the one hand, it can avoid the situation that the cutter head and the cutter holder are both made of hard alloy material and the sliding connection is prone to wear. On the other hand, it can provide a certain damping force. When the cutter head slider is slidably connected to the slide groove on the cutter holder, the cutter head can be initially fixed due to the elastic damping effect of the rubber pad, which facilitates the subsequent installation of the transverse locking screw and the longitudinal locking screw.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a bending cutting head structure, including a cutting head 1. A groove 3 is provided inside the lower end of the cutting head 1. A cutting head 4 is provided below the groove 3. A slider 401 is provided at the upper end of the cutting head 4. The slider 401 and the cutting head 4 are integrally formed and the cutting head 4 is slidably connected to the groove 3 in the cutting head 1 through the slider 401. Both sides of the cutting head 1 are provided with transverse screw holes 5 that penetrate into the slider 401. The rear end of the cutting head 1 is provided with a longitudinal screw hole 7 that penetrates into the slider 401. Both sides of the cutting head 1 are threadedly connected to the slider 401 through the transverse screw holes 5 and transverse locking screws 6. The rear end of the cutting head 1 is threadedly connected to the slider 401 through the longitudinal screw hole 7 and longitudinal locking screws 8. A connecting block 2 is provided at the upper end of the cutting head 1 and the connecting block 2 is integrally formed with the cutting head 1. Both the cutting head 1 and the cutting head 4 are made of alloy material.

[0023] The tool holder 1 is fixed to the mounting base via the connecting block 2. When installing the tool head 4, the tool head 4 is first slid into the groove 3 at the lower end of the tool holder 1 via the slider 401 on the tool head 4. After the tool head 4 presses against the inner wall of the groove 3, the longitudinal locking screw 8 is rotated and inserted along the longitudinal screw hole 7 at the rear end of the tool holder 1 to fix it to the rear end of the slider 401 of the tool head 4. After fixing, the two transverse locking screws 6 are respectively installed to the transverse screw holes 5 on both sides of the tool head 4. The transverse locking screws 6 are used to fix both sides of the slider 401 of the tool head 4. In this state, because the tool head 4 is simultaneously subjected to transverse and longitudinal locking forces, it has strong stability and can offset multi-directional stress when subjected to processing force, thus extending the processing life.

[0024] Please see Figure 1 and Figure 3 Two side limiting guide bars 9 are provided on both sides of the inside of the slide groove 3, and two guide grooves 402 are provided on both sides of the slider 401. The guide grooves 402 of the slider 401 are slidably connected with the side limiting guide bars 9. When the slider 401 of the cutter head 4 is slidably connected with the slide groove 3 on the cutter holder 1, the guide grooves 402 on both sides of the slider 401 can engage with the side limiting guide bars 9 on the side wall of the slide groove 3, thereby achieving the effect of upper and lower limiting support and further improving the stability of the cutter head 4 after connection.

[0025] Please see Figure 4 A rubber pad 10 is provided on the inner wall of the slide groove 3. The rubber pad 10 is made of flexible material. On the one hand, it can avoid the wear caused by the sliding connection between the cutter head 4 and the cutter holder 1, which are both made of hard alloy material. On the other hand, it can provide a certain damping force. When the slider 401 of the cutter head 4 slides and connects with the slide groove 3 on the cutter holder 1, the elastic damping effect of the rubber pad 10 can initially fix the cutter head 4, which is convenient for subsequent installation of the transverse locking screw 6 and the longitudinal locking screw 8.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
