Description

Technical Field

[0001] This utility model relates to the field of wrist cord heat cutting technology, and in particular to a wrist cord heat cutting device. Background Technology

[0002] In existing technologies, the cutting process of wrist straps usually relies on manual operation. Specifically, the worker needs to manually fix the cutting distance of the wrist strap and then operate the cutter to complete the cutting work. Since it is manual positioning and cutting, the cutting length will have errors due to different operators and slight differences in each operation, resulting in inconsistent lengths of the final product, which affects the consistency and reliability of product quality.

[0003] In addition, the cutter will inevitably wear down after prolonged use and become dull. A dull cutter not only reduces cutting efficiency, but also makes the cut surface uneven and smooth, and may even leave burrs or tears, which is extremely detrimental to the subsequent welding process.

[0004] Therefore, it is imperative to redesign a wrist cord heat-cutting device. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, this utility model provides a wrist rope hot cutting device, which aims to solve the problems of low dimensional accuracy, tool wear affecting cutting quality, and low production efficiency caused by the reliance on manual operation in the prior art for wrist rope cutting.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wrist cord hot-cutting device, including a machine base, on which a hot-cutting lower mold and a hot-cutting component located behind the hot-cutting lower mold are arranged. The output end of the hot-cutting component is located at the upper end of the hot-cutting lower mold. The hot-cutting lower mold consists of a wrist cord positioning part and a cutting positioning part. The upper middle part of the wrist cord positioning part is provided with a left-right wrist cord mounting groove. The upper end of the cutting positioning part is provided with a front-back hot-cutting blade groove. Two left-right single cord fitting arc grooves are provided on the hot-cutting blade groove corresponding to the position of each wrist cord mounting groove. The hot-cutting blade at the output end of the hot-cutting component passes through the hot-cutting blade groove to complete the hot-cutting of the wrist cord in the single cord fitting arc groove.

[0007] Based on the above, the beneficial effects of a wrist cord heat-cutting device are that it solves the problems of low dimensional accuracy, tool wear affecting cutting quality, and low production efficiency caused by manual operation in the prior art for wrist cord cutting; mainly reflected in:

[0008] 1. This utility model, through the hot cutting lower mold and hot cutting components configured on the machine, as well as the wrist rope positioning part and cutting positioning part included in the hot cutting lower mold, especially the wrist rope mounting groove on the cutting positioning part to position the wrist rope body and the single rope adapter arc groove to position the cutting end of the wrist rope, ensures the consistency of the wrist rope placement position each time, thereby greatly improving the accuracy of the cutting size and solving the problem of inconsistent product length caused by manual operation.

[0009] 2. This utility model realizes the hot cutting process through the application of heating elements and hot cutting blades in the hot cutting assembly, avoiding the problem of traditional cutters affecting the cutting quality due to wear. Hot cutting not only ensures the flatness and smoothness of the cut surface, but also effectively prevents the occurrence of burrs or tearing, which is beneficial to the subsequent welding process.

[0010] 3. This utility model also replaces the manual operation method with a hot-cutting component, which reduces labor costs and speeds up production.

[0011] Furthermore, the hot cutting assembly includes a hot cutting frame, a push cylinder, a sliding frame, a hot cutting cylinder, and a heating element. The push cylinder is disposed at the upper end of the hot cutting frame. A sliding rail is provided on the side of the hot cutting frame near the hot cutting lower mold. The sliding frame is disposed at the output end of the push cylinder and is slidably connected to the sliding rail. The hot cutting cylinder is installed inside the sliding frame. The heating element is disposed at the output end of the hot cutting cylinder. The hot cutting blade is disposed at the bottom end of the heating element and passes through the bottom end of the sliding frame to be adapted to the hot cutting blade groove.

[0012] Based on the above, the beneficial effect of the sliding frame moving smoothly up and down along the sliding track under the action of the downward-pushing cylinder is to ensure that the hot cutting blade can accurately reach the predetermined cutting position, thereby improving cutting accuracy and stability; the beneficial effect of the hot cutting blade being set at the bottom of the heating element is to ensure rapid heat transfer, achieve a high degree of controllability of the cutting process, and ensure that consistent results are obtained for each cut.

[0013] Furthermore, the bottom end of the sliding frame is provided with a blade positioning platform, and the blade positioning platform is provided with a blade positioning sliding hole that runs vertically through it, and the hot-cutting blade is slidably fitted into the blade positioning sliding hole.

[0014] Based on the above, the beneficial effect of having blade positioning sliding holes in the blade positioning stage is to ensure that the hot cutting blade always maintains a straight line when moving up and down, avoiding lateral offset or shaking, which helps to achieve a more accurate and straight cutting line, and improves the dimensional consistency and quality stability of the product.

[0015] Furthermore, a pressure sensor is installed inside the blade positioning stage to detect the contact force between the blade positioning stage and the cutting positioning part.

[0016] Furthermore, the blade positioning stage is also equipped with an ultrasonic generator.

[0017] Based on the above, the beneficial effect of the ultrasonic generator is that it generates ultrasonic vibrations to assist the hot-cutting blade in cutting the wrist strap.

[0018] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0023] like Figures 1-3 As shown, a wrist strap heat-cutting device includes a machine base 1, on which a heat-cutting lower mold 2 and a heat-cutting component 3 located behind the heat-cutting lower mold 2 are arranged. The output end of the heat-cutting component 3 is located at the upper end of the heat-cutting lower mold 2. The heat-cutting lower mold 2 is composed of a wrist strap positioning part 21 and a cutting positioning part 22. The upper middle part of the wrist strap positioning part 21 is provided with a left-right wrist strap mounting groove 211. The upper end of the cutting positioning part 22 is provided with a front-back heat-cutting blade groove 221. The heat-cutting blade groove 221 is provided with two left-right single-strand adapter arc grooves 222 corresponding to the position of each wrist strap mounting groove 211. The heat-cutting blade 31 at the output end of the heat-cutting component 3 passes through the heat-cutting blade groove 221 to complete the heat cutting of the wrist strap in the single-strand adapter arc groove 222.

[0024] The hot cutting assembly 3 includes a hot cutting frame 36, a push cylinder 32, a sliding frame 33, a hot cutting cylinder 34, and a heating element 35. The push cylinder 32 is disposed at the upper end of the hot cutting frame 36. A sliding rail 361 is provided on the side of the hot cutting lower mold 2 near the hot cutting frame 36. The sliding frame 33 is disposed at the output end of the push cylinder 32 and is slidably connected to the sliding rail 361. The hot cutting cylinder 34 is installed inside the sliding frame 33. The heating element 35 is disposed at the output end of the hot cutting cylinder 34. The hot cutting blade 31 is disposed at the bottom end of the heating element 35 and passes through the bottom end of the sliding frame 33 to be adapted to the hot cutting groove 221.

[0025] The bottom end of the sliding frame 33 is provided with a blade positioning platform 331, and the blade positioning platform 331 is provided with a blade positioning sliding hole 3311 that runs vertically through it. The hot cutting blade 31 is slidably fitted into the blade positioning sliding hole 3311.

[0026] The blade positioning stage 331 is equipped with a pressure sensor to detect the contact force between the blade positioning stage 331 and the cutting positioning part 22.

[0027] The blade positioning stage 331 is also equipped with an ultrasonic generator.

[0028] In summary, the specific implementation of this utility model is as follows: First, the operator places the wrist rope to be cut into the wrist rope positioning part 21 in the hot cutting lower die 2 on the machine 1. Specifically, the wrist rope is placed into the left and right wrist rope mounting groove 211 to ensure that the wrist rope is correctly positioned.

[0029] Then, the push cylinder 32 drives the sliding frame 33 to push downward along the sliding track 361, so that the bottom end of the blade positioning table 331 contacts the cutting positioning part 22. During this process, the pressure sensor continuously monitors the contact force between the blade positioning table 331 and the cutting positioning part 22 to avoid excessive pressure.

[0030] Next, the hot-cutting cylinder 34 drives the hot-cutting blade through the blade positioning sliding hole 3311 that runs vertically through the bottom of the sliding frame 33 and the blade positioning table 331, and into the hot-cutting groove 221 to perform a rapid and precise hot cut on the end of the wrist rope positioned in the single rope adapter arc groove 222. During this process, the heating element 35 provides heating to the hot-cutting blade 31, and the ultrasonic generator provides ultrasonic vibration to the hot-cutting blade 31 to assist in cutting. It should be noted that the ultrasonic generator helps to reduce the adhesion of the wrist rope to the blade and reduce cutting resistance.

[0031] After the hot cutting is completed, the hot cutting blade 31 will quickly retract under the action of the hot cutting cylinder 34, disengaging from the wrist rope and the hot cutting blade groove 221. The push cylinder 32 will then drive the sliding frame 33 back to the initial position, ready for the next round of operation.

[0032] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
