TECHNICAL FIELD
[0001] The utility model relates to a trimming tool belongs to shoemaking technical field, specifically a sole trimming device. BACKGROUND
[0002] In the shoemaking process, the production mode of the sole of rubber shoes is to put rubber or polyurethane forming material into the mold and then add high pressure to make it form, and a small part of glue will flow out at the joint of the mold, and the flowed glue is the water gate glue, and the cutting of the water gate glue is the key process to keep the appearance of the sole neat. The cutting of the water gate glue generally adopts machine cutting and manual cutting, and the hardness of the polyurethane sole is relatively large, and machine cutting is generally adopted, but for the sole with small hardness and soft material such as rubber, the effect of machine operation is not ideal, and there are problems of incomplete cutting or excessive cutting, therefore, workers generally use cutting tools to cut the water gate glue of the rubber sole. When trimming the water gate glue with the existing ordinary cutting tool, the following problems exist: the worker holds the cutting tool, the central axis of the cutting tool is perpendicular to the cutting forward direction, and the cutting edge is pushed forward by relying on wrist swing, and since the cutting tool is pushed in this way, the cutting force and direction are not accurate, the cutting is laborious, and the sole is easily cut, which affects the product quality and production efficiency. SUMMARY
[0003] In order to solve the above problems in the prior art, the utility model aims at providing a sole trimming device to accurately and labor-savingly cut the water gate glue.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sole trimming device, comprising a cutting part and a hand-held part, the cutting part is in the form of a sheet and is fixedly arranged at the front end of the hand-held part, and a U-shaped open type cutting edge recessed inward is arranged at the front end of the cutting part.
[0005] As a limitation of the utility model, the plane where the cutting part is located and the hand-held part form an included angle of 20°-30°.
[0006] As a limitation of the utility model, the included angle between the two sides of the cutting edge is 10°-15°, and the opening depth of the cutting edge is 5mm-10mm.
[0007] As a limitation of the utility model, a discharge groove extending to the hand-held part direction is arranged on the cutting part and communicated with the cutting edge.
[0008] As a limitation of the utility model, a hand guard handle convenient for gripping is arranged at the rear end of the hand-held part, and anti-slip lines are fixedly arranged on the outer surface of the hand guard handle.
[0009] As a limitation of the utility model, the cutting part and the hand-held part are integrally formed.
[0010] As the limitation of the utility model: the material of the cutting part and the handheld part is hard alloy.
[0011] Due to the adoption of the above technical scheme, compared with the prior art, the utility model has the beneficial effects that: the utility model opens a U-shaped open blade at the front end of the cutting part, the blade opening and the handheld part are in the same direction, when cutting, the blade is pushed forward by holding the handheld part, without bending the wrist to push, the whole hand to the arm is in the same plane with the sole operation surface, which can accurately and labor-savingly cut off the gate glue; at the same time, the plane where the cutting part is located is arranged at an angle with the handheld part, so that the cutting surface of the blade can always be kept at the connection between the gate glue and the sole, so that the cutting action is more accurate; in addition, the discharge groove can guide the strip-shaped material cut by the blade to the rear part, without blocking the blade, so as to facilitate the operator to accurately judge the cutting condition.
[0012] In summary, the utility model has the advantages of simple structure, convenient operation, accuracy, labor saving and no damage to the sole, and is suitable for cutting the gate glue at the soft sole. BRIEF DESCRIPTION OF DRAWINGS
[0013] The utility model will be further described in detail below in combination with the drawings and specific embodiments.
[0014] Figure 1 It is a structure schematic view of the utility model embodiment;
[0015] Figure 2 It is a use state schematic view of the utility model embodiment.
[0016] In the drawing: 1-cutting part, 2-handheld part, 3-blade, 4-discharge groove, 5-gate glue. DETAILED DESCRIPTION
[0017] The preferred embodiments of the utility model will be described below in combination with the drawings. It should be understood that the shoe sole trimmer described herein is a preferred embodiment, which is only used to illustrate and explain the utility model, and does not constitute a limitation on the utility model.
[0018] The "up", "down", "left", "right" and other orientation words or position relationships in the utility model are based on the orientation relationship of the drawings of the utility model specification, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element must have a specific orientation, a specific orientation structure and operation, therefore, it cannot be understood as a limitation on the content protected by the utility model. EMBODIMENT
[0019] The present embodiment is Figure 1 , Figure 2The image shows a shoe sole trimming tool, comprising a cutting part 1 and a handle part 2. The cutting part 1 is a thin sheet fixed to the front end of the handle part 2. A U-shaped open blade 3, recessed towards the rear end, is formed at the front end of the cutting part 1. The width of the opening of the blade 3 is greater than the width of the U-shaped bottom of the blade 3; when the opening of the blade 3 is large, it can approach a V-shape. The plane containing the cutting part 1 forms an angle of 20° to 30° with the handle part 2, meaning the cutting part 1 is in a bent-head state. The angle formed between the two edges of the blade 3 is 10° to 15°, and the opening depth of the blade 3 is 5mm to 10mm. The width and depth of the blade 3 opening should be selected based on the shape of the sprue residue 5 to be trimmed.
[0020] A discharge groove 4, which is connected to the cutting edge 3, is also provided on the cutting part 1. The discharge groove 4 can guide the material cut off at the U-shaped cutting edge 3 to the rear, so as not to block the cutting edge 3 and thus affect the operator's accuracy in judging the cutting part.
[0021] The cutting part 1 and the hand-held part 2 are made of cemented carbide. The cutting part 1 and the hand-held part 2 can be integrally formed or assembled. A protective handle (not shown in the figure) is provided at the rear end of the hand-held part 2 for easy gripping. The outer surface of the protective handle is fixed with anti-slip texture to facilitate worker gripping and operation.
[0022] When using this embodiment, as Figure 2 As shown, align the U-shaped open blade 3 with the sprue glue 5 on the sole, hold the holding part 2 with your hand, and push forward to cut. Pushing forward with your hand allows you to accurately control the cutting force and direction, making it less likely to damage the sole and saving effort in cutting.
