A new type of tooling fixture

Abstract

This utility model discloses a novel tooling fixture, including a base and a lower die mounted on the base. The lower die works in conjunction with a stamping machine to shear raw materials. A roller is driven to contact the side of the raw material, guiding its movement on the lower die and changing the stamping position. A linear adjustment mechanism changes the distance between two inverted U-shaped frames to accommodate long strips of raw materials of different widths. A cylinder pushes a clamping plate to fix the raw material during stamping, preventing stamping obstruction. A synchronous motor simultaneously drives a lead screw to rotate, allowing the inverted U-shaped frames to move synchronously closer or further apart. The lower die, fixed with bolts, is easy to disassemble and replace. A fixing plate, along with bolts, secures the base to the stamping table. A guide ramp guides and collects the stamped parts.

Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a novel tooling fixture. Background Technology

[0002] Originally, textiles referred to the general concepts of spinning and weaving. However, with the continuous development and improvement of textile knowledge and disciplines, especially with the emergence of technologies such as nonwoven textile materials and three-dimensional composite weaving, it has expanded beyond traditional hand spinning and weaving to include nonwoven fabric technology, modern three-dimensional weaving technology, and modern electrostatic nanofiber web forming technology, producing apparel, industrial, and decorative textiles. Therefore, modern textiles refer to a multi-scale structural processing technology for fibers or fiber assemblies. Textile machines, also known as spinning machines, looms, cotton spinning machines, etc., are machines used in textile production. They are the tools used to process raw materials such as thread, silk, and hemp into yarn and then weave it into fabric. They include machines such as spinning wheels, spinning spools, treadle looms, modern mechanical looms, and modern CNC automatic looms. Current textile machines contain various components, some of which are typically manufactured by stamping (such as metal tension sheets). During the production of textile components, raw materials (most textile components are made of long strips of metal) need to be continuously fed into the stamping machine. Tooling fixtures are installed below the stamping machine to hold and fix the raw materials to be stamped, thus preventing the raw materials from deviating during stamping and causing stamping problems. However, current tooling fixtures are not convenient for adjusting the position of long strips of raw materials, requiring manual repositioning, which is very troublesome and poses certain dangers. Therefore, a new type of tooling fixture is needed to solve the above problems. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a novel tooling fixture. The technical solution adopted includes a base and a lower mold disposed on the base. An installation groove is formed on the upper surface of the base, and the installation groove is located on the left and right sides of the lower mold. A linear adjustment mechanism is disposed within the installation groove. A clamping unit is disposed above the lower mold. The clamping unit includes an inverted U-shaped frame, a drive roller, a cylinder, and a clamping plate. There are two inverted U-shaped frames, which are symmetrical front and back. The lower part of the vertical plates at the left and right ends of the inverted U-shaped frames is connected to the linear adjustment mechanism, and the two inverted U-shaped frames move closer or further apart synchronously. The horizontal plate of the inverted U-shaped frame... The lower surface contacts the upper surface of the lower die. The driving roller is uniformly rotated and set on the inner side of the horizontal plate of the inverted U-shaped frame. The cylinder is set on the outer side of the left and right ends of the horizontal plate of the inverted U-shaped frame. The telescopic shaft of the cylinder extends into the inner side of the inverted U-shaped frame and connects to the clamping plate. The lower die cooperates with the stamping machine to shear the raw material. The driving roller contacts the side of the raw material, so that it can be guided and moved on the lower die, thereby changing the stamping position. The distance between the two inverted U-shaped frames is changed by the linear adjustment mechanism to accommodate long strip raw materials of different widths. The cylinder pushes the clamping plate to fix the raw material during stamping and avoid the occurrence of stamping problems.

[0004] As a preferred technical solution of the novel tooling fixture of this utility model, the adjustment mechanism includes a fixed block, a lead screw, a slide rod, and a synchronous motor. The fixed block is set at both ends of the mounting groove. The lead screw and the slide rod are respectively rotatably and fixedly set between the two fixed blocks. The synchronous motor is set on the fixed block, and the output shaft of the synchronous motor is connected to the lead screw. The vertical plate of the inverted U-shaped frame is threaded to the lead screw and slidably sleeved on the slide rod. The synchronous motor drives the lead screw to rotate simultaneously, thereby realizing the synchronous approach or departure of the inverted U-shaped frame.

[0005] As a preferred technical solution of the new tooling fixture of this utility model, the lower mold is fixed to the base by bolts, and the lower mold fixed by bolts is easy to disassemble and replace.

[0006] As a preferred technical solution of the new tooling fixture of this utility model, the bottom of the base is provided with a fixing plate, and the fixing plate is provided with fixing holes. The base can be fixed on the stamping table by means of the fixing plate and bolts.

[0007] As a preferred technical solution of a novel tooling fixture of this utility model, the base is provided with a guide slope and is located below the lower mold. The guide slope can guide and collect the molded products after stamping and separation.

[0008] As a preferred technical solution of the new tooling fixture of this utility model, after the telescopic shaft of the cylinder retracts, the clamping plate is located outside the driving roller. By restricting the retraction position of the clamping plate, it is possible to prevent the clamping plate from affecting the movement of raw materials.

[0009] The beneficial effects of this utility model are as follows: This utility model uses a lower die to cooperate with a stamping machine to shear the raw material. By driving the roller to contact the side of the raw material, it can be guided and moved on the lower die, thereby changing the stamping position. A linear adjustment mechanism can change the distance between the two inverted U-shaped frames to accommodate long strip-shaped raw materials of different widths. A cylinder pushes the clamping plate to fix the raw material during stamping, avoiding stamping obstruction. A synchronous motor drives the lead screw to rotate simultaneously, thereby realizing the synchronous approach or departure of the inverted U-shaped frames. The lower die, fixed with bolts, is easy to disassemble and replace. A fixing plate, together with bolts, can fix the base to the stamping table. A guide slope can guide and collect the formed products after stamping separation. By limiting the contraction position of the clamping plate, it can prevent the clamping plate from affecting the movement of the raw material. Attached Figure Description

Detailed Implementation

[0014] Example 1

[0015] like Figures 1 to 3As shown, this utility model discloses a novel tooling fixture. The technical solution includes a base 1 and a lower mold 2 mounted on the base. The lower mold 2 is fixed to the base 1 by bolts, facilitating disassembly and replacement. A guide ramp 103 is provided on the base 1, located below the lower mold 2. The guide ramp 103 guides and collects the stamped parts after separation. A fixing plate 102 is provided at the bottom of the base 1, with fixing holes. The base 1 is fixed to the stamping table by bolts. An mounting groove 101 is provided on the upper surface of the base 1. The mounting slots 101 are located on the left and right sides of the lower mold 2; a linear adjustment mechanism 3 is provided inside the mounting slots 101; a clamping unit 4 is provided above the lower mold 2, the clamping unit 4 including an inverted U-shaped frame 41, a driving roller 42, a cylinder 43 and a clamping plate 44. There are two inverted U-shaped frames 41, which are symmetrical front and back. The lower part of the vertical plates at the left and right ends of the inverted U-shaped frames 41 is connected to the linear adjustment mechanism 3, and the two inverted U-shaped frames 41 move closer or further away at the same time. The lower surface of the horizontal plate of the inverted U-shaped frame 41 contacts the upper surface of the lower mold 2. The driving roller 42 is uniformly rotated and is set on the inner side of the horizontal plate of the inverted U-shaped frame 41. The cylinder 43 is set on the inverted U-shaped frame 41. On the outer sides of the left and right ends of the horizontal plate, the telescopic shaft of the cylinder 43 extends into the inner side of the inverted U-shaped frame 41 and connects to the clamping plate 44. The adjusting mechanism 3 includes a fixed block 31, a lead screw 32, a slide rod 33, and a synchronous motor 34. The fixed block 31 is located at the front and rear ends of the mounting groove 101. The lead screw 32 and the slide rod 33 are respectively rotatably and fixedly mounted between the two fixed blocks 31. The synchronous motor 34 is mounted on the fixed block 31, and the output shaft of the synchronous motor 34 is connected to the lead screw 32. The vertical plate of the inverted U-shaped frame 41 is threaded to the lead screw 32 and slidably sleeved on the slide rod 33. The synchronous motor 34 drives the lead screw 32 to rotate simultaneously, thereby realizing the inverted U-shape. When the frame 41 moves closer or further away, the telescopic shaft of the cylinder 43 retracts, and the clamping plate 44 is located outside the drive roller 42. By limiting the retraction position of the clamping plate 44, it can prevent the clamping plate 44 from affecting the movement of the raw material. The lower die 2 cooperates with the stamping machine to shear the raw material. The drive roller 42 contacts the side of the raw material, so that it can be guided to move on the lower die 2, thereby changing the stamping position. The linear adjustment mechanism 3 changes the distance between the two inverted U-shaped frames 41 to accommodate long strip raw materials of different widths. The cylinder 43 pushes the clamping plate 44 to fix the raw material during stamping and avoid the occurrence of stamping problems.

[0016] The working principle of this utility model is as follows: The base 1 is fixed to the stamping table using bolts and fixing holes on the fixing plate 102. The strip-shaped raw material is placed on the lower mold 2. The synchronous motor 34 is started, and the two inverted U-shaped frames 41 move closer to each other, driving the roller 42 to contact the side of the raw material. When stamping begins, the cylinder 43 is started, the clamping plate 44 extends to clamp the raw material, and the upper mold descends to start stamping. The stamped product falls to the guide slope 103 and is then discharged. After stamping is completed, the upper mold rises, the cylinder 43 retracts, and then pushes the raw material, driving the roller 42 to rotate and guide the raw material, thus changing the stamping position of the raw material. The above process is repeated to perform uninterrupted stamping. The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.
